Description

Breath analyzer

[ technical field ] A method for producing a semiconductor device

The utility model relates to a human medical technology field, specificly relate to a breath analyzer.

[ background of the invention ]

One example of an abnormality in breathing during Sleep is Sleep apnea (Sleep Apnoea), a possibility of Sleep disturbance. Patients often suffocate with apnea many times during sleep (10 seconds more pauses in breathing) or semi-apneic (50% of the respiratory flow remains and lasts more than 10 seconds). The patient will therefore struggle to wake up as a result of the decreased respiration, which will result in a decreased blood oxygen content. After waking up, the breath returns to normal and then enters sleep again. The medicine can be repeatedly taken ten to hundreds of times every night, and is averagely repeated for more than 5 times every hour.

Sleep apnea can also be divided into two categories, the first being Obstructive Sleep apnea (obsessive Sleep apnea), with hundreds of ninety Sleep apnea patients belonging to this category. When a patient sleeps, soft tissues near the throat are loosened to block the upper respiratory tract, so that the respiratory tract is narrowed to cause asphyxia. The second is Central brain Sleep apnea (Central Sleep Apnoea), where the patient's brain fails to give respiratory instructions due to damage from stroke, trauma, etc., such that normal breathing rhythm cannot proceed.

If the patient is not properly diagnosed, the patient can affect the health for a long time, such as hypertension, heart failure, impaired lung function, stroke, traffic accident and even sudden death. The huge number of patients in China is a heavy burden for the national medical system and the economy.

In view of the above, it is desirable to provide a breath analyzer to overcome the deficiencies of the prior art.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 4, the present invention provides a breath analyzer.

In an embodiment of the present invention, the breath analyzer comprises a vest-shaped wearable device 10 and a data processing device 20;

the vest-shaped wearable device 10 comprises a vest-shaped fabric 11, an extensible tension belt 12 tied on the vest-shaped fabric 11, a tension sensor 13 arranged on the extensible tension belt 12, a circuit board 14 and a power supply 15; the circuit board 14 is provided with an amplifying module 16 electrically connected with the tension sensor 13, an analog-to-digital conversion module 17 electrically connected with the amplifying module 16, and a radio communication transmission module 18 electrically connected with the analog-to-digital conversion module 17;

the data processing device 20 includes a radio communication receiving module 21 wirelessly connected to the radio communication transmitting module 18, a processing module 22 electrically connected to the radio communication receiving module 21, and an alarm/display reporting module 23 electrically connected to the processing module 22.

It can be understood that the principle of the respiration analyzer is to sense the respiration of a person by using the contraction and expansion of the abdomen, and calculate whether the respiration of the patient is stopped or too little. The human respiratory cycle consists of the first half of the week "exhaling" and the second half of the week "inhaling" to form a complete respiratory cycle. The first half of the cycle is to expel air from the lungs, where the diaphragm moves upwards and the stomach becomes smaller. The second half of the cycle is when air is drawn into the lungs, where the diaphragm moves downward and the stomach expands.

In order to sense the contraction and expansion of the abdomen, the stretchable tension band 12 is designed in a loop shape or called a loop having a length just one turn around the abdomen by putting the vest-shaped fabric 11 on the human body, and the material is highly elastic and stretchable. Thus, the circumference of the extensible tension band 12 will follow the expansion and contraction of the abdomen without exerting too much pressure on the patient's abdomen as with the belt of pants. When the patient breathes, the abdomen is correspondingly contracted and expanded, the tension sensor 13 detects the change of the circumference of the abdomen and transmits a signal to the amplifying module 16, the amplifying module 16 amplifies the signal and then wirelessly transmits the amplified signal to the radio communication receiving module 21 through the analog-to-digital conversion module 17, and the processing module 22 stores and analyzes the output received by the radio communication receiving module 21 and finally controls the alarm/display reporting module 23.

At the beginning of use, the system will first analyze using default standard parameters. At the same time, the system will use the initial part time data to make self-correction of normal respiration, and the period and amplitude of respiration will be different with time. The system will first detect the respiratory cycle and then count the frequency density and amplitude of the cycle to assess whether sleep apnea is occurring. The normal person sleeps with a breathing rate of about 16 to 18 breaths per minute, and the system uses this number as a default value, and the user can also adjust to the number he or she believes to be correct. When the system counts that the breathing cycle is within this range, no alarm signal is issued, but when the number is outside this range, the system will issue a warning. The system also warns when the amplitude of the breath is 50% or more less than normal. Of course, 50% is only a default value, which allows the user to adjust to other numbers. The number is calculated by the area of the amplitude and time of the respiratory cycle, and the default statistical time of the frequency and the amplitude is one minute, so that the teaching can be freely carried out.

Because the data is transmitted in a radio mode, doctors can observe the sleeping condition and the illness process of the patients in a house separated by one wall, the parameters can be adjusted at any time without disturbing the patients, and the optimal diagnosis and analysis effects are achieved. During the period, even if an alarm exists, the alarm can be set to be sent to the doctor and not to the patient, so that the sleep can be continued, the observation can be more durable, and the decision is made to be owned by the doctor. All the original data parameters and the processing results are stored in the process for the user or doctor to refer to later.

The respiration signal is stored and processed in real time after being received. The signal processing includes finding the amplitude and period of respiration, and when the amplitude of the signal is too weak, it is considered that there is no respiration. When a plurality of consecutive respiratory signals are not expected to occur, the patient is considered to have a sleep apnea episode. The system may then emit audio or other means such as vibration or glare, waking the patient, caregiver, or family.

Further, referring to fig. 2, the tension sensor 13 includes a reaction frame 131 and 4 strain gauges 132 disposed on the reaction frame 131. The reaction frame 131 is generally made of a metal material because the metal is generally relatively long in extensibility. The reaction frame 131 is attached with 4 strain gauges 132(strain gauge), and the four strain gauges 132 are respectively attached to four symmetrical positions of the reaction plate to form a wheatstone bridge for sensing the strain at the position. Under this configuration, as the pulling force increases, the strains of two of the strain gauges 132 increase and increase in the same magnitude, while the strains of the other two decrease; when the pulling force is reduced, the strains of two of the strain gauges 132 are reduced, and the strains of the other two are increased. Due to the symmetry, the strain gauges 132 of the 4 strain gauges 132 will have the same magnitude whether they are increased or decreased.

The Strain gauge 132(Strain gauge) is a basic sensing component of the present invention, and its equivalent circuit is a variable resistor. The four strain gauges 132 are connected to form a Wheatstone bridge (Wheatstone bridge), and the signals from the left two resistors and the right two resistors are push-pull interacted. That is, when the voltage between the two left resistors increases, the voltage between the two right resistors decreases by the same magnitude. Thus, the tension variation will produce a double electrical signal variation and the environmental noise (including temperature variation and radio wave interference) will cancel each other out. This is also an advantage of the bridge circuit.

In one embodiment, the vest-shaped fabric 11 includes three sizes of a large size, a medium size, and a small size. So as to adapt to patients with different body sizes.

In one embodiment, the extensible tension band 12 is a length adjustable waist band. The size of the utility model can be adjusted to adapt to patients with different body sizes.

In one embodiment, the wearable device 10 and the data processing device 20 are two separate components, and are wirelessly connected to the wireless communication receiving module 21 through the wireless communication transmitting module 18.

Compared with the prior art, the utility model provides a pair of breath analyzer's beneficial effect lies in: the breathing cycle of a patient is detected through a tension sensor on a vest-shaped wearable device, then data are transmitted to a data processing device through a radio signal, the data processing device can evaluate whether breathing problems occur or not according to the change of the breathing amplitude and the cycle time, and can send an alarm to wake up the patient so as to stop the duration of the asphyxia condition and avoid the life danger caused by serious health problems; meanwhile, the user can judge whether to agree with the judgment made by the system or not according to the acquired data and the processing result, so that the system has a certain basis, and the accuracy is improved; the data and results can also be stored for follow-up by a physician or other practitioner.
