Over-the-Counter (OTC) hearing aids have emerged as a game-changer in the hearing healthcare industry, offering increased accessibility and affordability to individuals with mild to moderate hearing loss. This paradigm shift in the availability of hearing aids is largely due to the FDA's groundbreaking policy, which has paved the way for OTC devices to enter the market without the need for a prescription or professional fitting.
One of the primary reasons OTC hearing aids are more affordable is the elimination of professional services such as evaluations, fittings, and ongoing support. By bypassing these services, manufacturers can reduce production costs and pass on the savings to consumers.
However, despite the availability of OTC hearing aids, many individuals still face barriers to accessing these devices. Factors such as lack of awareness, stigma surrounding hearing loss, and limited distribution channels can hinder people's ability to obtain OTC hearing aids.
Recognizing these challenges, Wellue is on a mission to make OTC hearing aids accessible to everyone. Wellue aims to raise awareness about hearing health and empower individuals to take control of their hearing by providing high-quality, affordable OTC hearing aids.
Here's the key features of OTC hearing aids:
Digital noise reduction is a vital feature that enhances listening performance in noisy environments. By selectively blocking out background noise, this technology makes it easier to hear and understand speech, even in challenging noisy conditions. According to a survey, a majority of respondents identified digital noise reduction as the most important feature they desired in a hearing aid, highlighting its significance in improving overall hearing satisfaction.
Crystal-clear hearing, even in noisy environments: restaurants, subways, or windy outdoors. We've got you covered.
Directional microphones play a crucial role in improving speech understanding, especially in noisy environments. These microphones identify and amplify sounds coming from the front while reducing background noise from the rear or sides, creating a clearer listening experience. They work best when you're close to the sound source, capturing more sound details.
You can hear more of the person you're talking to and fade background noise away. Focus on what matters.
Feedback suppression technology is designed to minimize the occurrence of high-pitched whistling sounds, commonly known as feedback. This feature is particularly useful when using telephones or experiencing slight movements of the hearing aid within the ear. By reducing feedback, users can enjoy improved sound quality and comfort during daily activities.
Comfortable listening experience in everyday life.
Rechargeable hearing aid batteries have simplified the maintenance process by eliminating the need for frequent battery replacements. Users can recharge their devices overnight by placing them in a charging dock, ensuring they are ready for use the next day. This convenient feature not only saves time and money but also promotes environmental sustainability by reducing battery waste.
Say goodbye to tiny batteries. Charge at night and you're ready to go in the morning.
Advanced OTC hearing aids offer multiple preprogrammed settings for various listening needs and environments. This allows users to seamlessly switch between settings optimized for different environments
Improve the overall comfort and clarity of your hearing - wherever you go.
Some hearing aids connect wirelessly to smartphone applications for remote control, enable users to fine-tune settings without touching the device. Users could also adjust the left & right hearing aids seperately.
Precise & remote control over your hearing aids.
Some hearing aids with phone application offer free in-app hearing test. Users can also input their audiogram, the device will automatically adjusts the setting to best fit you.
Precise hearing compensation tailed to your unique hearing loss.
Getting used to a hearing aid is a gradual process that requires patience and perseverance. As you embark on this journey, you'll likely notice a gradual improvement in your ability to hear and engage with the world around you. It's important to understand that wearing a hearing aid will alter your hearing experience, including the way your own voice sounds.
While it won't restore your hearing to normal, the device improves your ability to hear. Give yourself time to adapt, practicing in different environments to familiarize yourself with the varied listening experiences. Seek support from family, friends, or support groups. By wearing your hearing aid regularly, you can maximize its benefits and find one that enhances your ability to hear and communicate effectively, ultimately improving your quality of life.
Wellue OTC hearing aids combines cutting-edge technology with affordability, ensuring that everyone can access high-quality hearing solutions. With a commitment to improving hearing health for all, Wellue is leading the way towards a future where better hearing is within reach for everyone.
The instrument provides measurements of the gestational age of animals such as equine, bovine, ovine, swine, feline, and canine. By measuring the gestational sac (GS), body length (BL), heart length (HL), stomach length (SL), umbilical ridge length (USD), head circumference (HC), biparietal diameter (BPD), crown-rump length ( CRL) and other parameters, the instrument automatically displays the corresponding gestational age (gestational week).
Operation procedure
Press the “OBC” button to display the obstetric table menu as shown below:
Use the up and down keys to select the corresponding maternity table set, press the "OK" button to select the measurement item. After selecting the obstetric episode of the corresponding animal, the distance value of the selected parameter is measured according to the distance measurement method, and the corresponding gestational age data is automatically displayed on the left side of the screen, and the gestational age is displayed after the “W-D”.
Examination procedure:
1. Keep the sow in a standing position.
2. The probe is placed at the left or right side of the center of the abdominal wall of the ventral side, close to the abdominal wall, just above the teat and from the cranial bone to the side of the hind leg. If there is mud on the skin of this part, it should be washed first with water to prevent the structure of the abdominal pelvis from not being correctly presented.

3. To measure the long axis of the heart, the screen should display the maximum vertical axis value of the heart. As the gestational age increases, the fetal heart long axis increases regularly. The measurement method is as follows:
Schematic diagram of pig's heart long axis measurement
4. The distance value of the selected parameter is measured according to the distance measurement method, and the corresponding gestational age data is automatically displayed on the left side of the screen.
1. Keep the pig in a standing position.
2. The probe is placed at the left or right side of the center of the abdominal wall of the ventral side, close to
the abdominal wall. If there is mud on the skin of this part, it should be cleaned with water first to prevent the
structure of the abdominal pelvis from not being correctly presented.
3. The screen should be able to display the maximum vertical axis value of the stomach. As the gestational
age increases, the regularity of the fetal stomach long axis increases.
The method of measuring the longest axis of the stomach is shown in the figure:
Schematic diagram of pig's stomach long axis measurement
4. The distance value of the selected parameter is measured according to the distance measurement method, and the corresponding gestational age data is automatically displayed on the left side of the screen.
Procedure:
1. Clean up the excrement in the rectum of the bovine.
2. A preliminary assessment of the pregnancy status is then made by hand palpation to determine the reproductive tissue that will be scanned with B-ultrasound.
3. Hold the probe and insert hand and probe together into the rectum of the bovine. Hold the probe tightly to
ensure that any conditions that occur later can be felt first by hand, hand placed between the rectal wall and the
probe.
4. The internal structure of the cow is displayed on the screen, and the longitudinally intersecting part is the
bladder, followed by the cervical tissue and the uterus. Viewed horizontally, the uterine horn usually looks
circular. The probe moves inside the ventral back until the junction of the uterine horn and the uterus is observed, and then slowly deflects toward the uterine horn, as shown below:
5. To measure the diameter of the fetal torso, a longitudinal section should be chosen, ie through the sides of
the fetal neck, chest and abdomen from both sides. The torso diameter can be measured between 60 and 150 days
of pregnancy. The method of measuring the diameter of the trunk is shown in the figure:
6. The distance value of the selected parameter is measured according to the distance measurement method, and the corresponding gestational age data is automatically displayed on the left side of the screen.

There are two ways to detect pregnant ewes with B-ultrasound:
For the detection of the abdomen, use a mechanical sector probe or a line array probe; for the rectum, use a
rectal probe. These two methods are useful for confirming whether pregnant or not. According to some published materials, we believe that both methods have proven effective in the diagnosis of pregnancy.
— The method of rectal examination within 35 days of pregnancy is more accurate than the method of abdominal examination;
— Both methods are equally useful within 35 to 70 days of pregnancy. — After 70 days of pregnancy, the method of detecting with the abdomen is better because the uterus becomes larger at the time and this method is more practical.
1. Abdominal testing can be performed while the ewes are standing or lying/sitting. The probe is placed in a predetermined area of the skin without hair on the skin in the middle of the abdomen.
2. If there is mud on the skin of this part, it should be washed first with water to prevent the structure of the abdominal pelvis from not being correctly presented.
3. The length of the trunk is measured.
4. The distance value of the selected parameter is measured according to the distance measurement method.

Equine examination procedure:
1. Clean up the excrement in the horse's rectum.
2. A preliminary assessment of the pregnancy status is then made by hand palpation to determine the
reproductive tissue that will be scanned with B-ultrasound.
3. Insert the probe into the rectum of the horse with your hand and hold the probe tightly to ensure that any conditions that occur later can be felt first by hand, hand is on back side, between the rectal wall and the transducer.
4. The internal structure of the horse is displayed on the screen, and the longitudinally intersecting part is the bladder, followed by the cervical tissue and the uterus. Viewed horizontally, the uterine horn usually looks circular. The probe moves in the ventral back until the junction of the uterine horn and the uterus is observed, and then slowly deflects toward the horn, as shown in the following figure:

5. The measurement method of the diameter of the gestational sac is as follows, and the measurement can be performed from the horizontal direction or the vertical direction. There is no difference between the two methods.
Horse gestational age measurement
6. The distance value of the selected parameter is measured according to the distance measurement method. By measuring, we can create a chart to determine the growth curve and use this to determine the pregnancy time corresponding to the size of the embryo. Gestational age refers to the date of mating rather than counting from the date of fertilization.
Measuring the diameter of the head is to measure the maximum diameter of the interior of the skull from between the ventral and dorsal sides. This diameter can be measured before 8 weeks of pregnancy. The method of measuring the diameter of the head is as follows:
Cat head diameter measurement diagram
After the formation of the fetal head, BPD measurement has become a routine for ultrasound examination. Measuring method:
1. The plane of the fetal head axis is scanned and the standard plane of BPD measurement is searched from
top to bottom.
2. The distance value of the selected parameter is measured according to the distance measurement method.

Sleep apnea is a sleep disorder that causes a person to stop breathing for short periods while sleeping. The most common type of sleep apnea is obstructive sleep apnea, which occurs when the airway becomes partially or completely blocked during sleep. If left untreated, sleep apnea can lead to a range of health problems, including high blood pressure, heart disease, and stroke. Here are some warning signs of sleep apnea:
This is the most common sign of sleep apnea. It is usually loud and may include pauses or gasps.
This can be a sign that you have stopped breathing and your body is trying to get air.
If you feel tired during the day despite getting enough sleep at night, you may have sleep apnea.
Sleep apnea can cause low oxygen levels in the blood, which can lead to headaches in the morning.
Sleep apnea can cause daytime fatigue, which can make it hard to focus and concentrate.
Sleep apnea can cause irritability, depression, and other mood changes.
Breathing through the mouth can cause dry mouth or sore throat.
If you toss and turn a lot during sleep, it may be a sign of sleep apnea.
If you experience any of these symptoms, it is important to see a doctor for a diagnosis and treatment.
Here are some steps to diagnose sleep apnea:
1. Consult a doctor
If you suspect you have sleep apnea, the first step is to visit a doctor. Your doctor will take a medical history and perform a physical exam.
2. Discuss symptoms
Tell your doctor about your symptoms, including loud snoring, gasping for air during sleep, feeling tired after a full night's sleep, and morning headaches.
3. Take a sleep study
A sleep study, also called a polysomnogram, is the most common way to diagnose sleep apnea. You may be asked to spend the night at a sleep center, where your breathing, heart rate, and brain activity will be monitored.

Hypoxemia is caused by having low blood oxygen levels. Whether you have breathing issues or due to another cause such as piloting, hypoxemia can be serious and lead to hypoxia.
Hypoxia tends to come after hypoxemia. This is a condition that is caused by your body tissue not getting enough oxygen. When this happens, it can lead to brain, lung, and other parts of your body being damaged.
When you have hypoxia, your skin may change color and you may feel disoriented. It can be hard to breathe and you may sweat or feel anxiety. Should you suspect you have hypoxia, it is important for you to seek help ASAP. Hypoxia can have long-lasting effects, and it can be fatal.
If you feel the urge to cough, avoid doing so. This can cause stress on your lungs and lead to damage. It’s important to remain as calm as possible when seeking help for hypoxia.
When you seek help, you will go to the hospital and get your oxygen level checked out. You may have oxygen pumped into you until your levels go back to normal. Sometimes, you may be given an inhaler or another medicine that helps with your oxygen levels. Hypoxia treatments can range from being quick to involving complex machinery, depending on how severe it is.
Hypoxia can happen at any age. In childhood, it could be due to asthma issues. If you have other issues like COPD, bronchitis, pneumonia, and fluid in the lungs, it can lead to hypoxia as well.
Some medications that can make it hard for you to breathe can lead to hypoxia as well. This includes strong painkillers, so talk to your doctor before you have it. Heart issues and anemia can lead to hypoxia as well. While this is very unlikely, being poisoned by cyanide can lead to hypoxia as well.
If you have asthma, it’s important for you to take care of yourself. Eat right, exercise, and avoid anything that triggers it. In addition, it’s important for you to have triggers as well.
When you are a pilot, you are susceptible to hypoxia. The most common form you may encounter is known as altitude hypoxia. This tends to happen because you are flying in an aircraft that is not pressurized.
As you go higher in the air, the air molecules start to spread. This causes the partial pressure to go down. What does this mean? Basically, when you go high enough, it’s difficult for your lungs to transfer oxygen to your body.
If you are flying in an aircraft that is not pressurized, it’s important for you to take precautions and have backup oxygen in case if a pressurized aircraft starts losing pressure. All commercial aircrafts will have supplemental oxygen in case something happens.
Sometimes, you may not experience a reaction. This is due to the fact that there are several factors that will determine how you react. For one thing, it can be due to how fast you ascend and how long you spend in the air. It can be determined by what physical activity you are doing when you’re in the air, as well as the temperature in the air. How fit you are can determine your reaction, too.
Whether you’re a pilot or you have a condition that makes it possible to be exposed to hypoxia, it’s important to monitor the oxygen in your blood. This can help you figure out whether or not you are at risk, and allow you to get help as soon as possible. There are many different monitoring devices to help measure your levels, from fitness watches to O2 rings.
One O2 ring you should consider is the Wellue O2 ring. This is a ring you put over your finger, and it monitors your oxygen levels up to 16 hours on a single charge.
It is meant to be an overnight tracker, but it can also be worn on a long flight, too. When you are flying, having a ring over your finger can ensure security. Should your oxygen levels drop below a certain level, the ring will alert you through a vibration.
Like any other fitness tracker, you can use an app to keep track of your stats. You can also share your reports with your doctor. With that said, you do not need to have a smartphone to make it work, which is important when you’re high up in the air. It’s affordable, yet is made from tech that will deliver accurate readings every time of day.
Should your levels go down, you will get an alert. You may want to descend and get some oxygen ASAP in that case.
Hypoxia is no joke. Your body needs oxygen to live, and as soon as it’s not getting enough, it can start shutting down. In some cases, not treating hypoxia can lead to various health problems along the way. When you are a pilot or when you have health issues, it’s important to keep track of your blood oxygen levels and don’t hesitate when they drop below a certain level to seek help.
As mentioned, it can happen to airline pilots, but anyone of any career can experience it as well. Before you fly high in the air or before you do anything major while having breathing conditions, get yourself an oxygen monitor. You will be glad that you did whenever you are able to monitor your blood levels and get help as soon as your levels drop.
