Problems solved by technology

This patent can only judge whether the breathing has stopped, the depth of breathing, and the irregular breathing by the size of the response value. It does not monitor the time ratio of exhalation and inhalation. The porous humidity sensing material has a large response current under low humidity conditions. Safety level, the current is too small, it is not easy to monitor, and it is easy to be interfered by other external factors
[0014] For devices that are in close contact with the patient's airway, it is one of the clinical requirements to discard them after use. However, many devices for monitoring breathing in the prior art are complex in structure, expensive, and reusable, and their cleaning facilities are not complete, and there are not enough High purity, combined with reduced levels of patient immunity to bacteria and viruses, makes contaminated reusable devices prone to cross-contamination between different patients

Embodiment 1

[0052] Such as figure 2 As shown, an ultra-light wearable breathing monitoring instrument includes a wearable device 3 on which a breathing detector 2 and a sensing circuit are installed.

[0053] The respiration detector 2 is used to detect changes in humidity, respiration time, etc. during respiration, and is an elastomer prepared by uniformly mixing and curing an elastic conductive colloid with a chain structure and a flexible high molecular polymer.

[0054] The sensing circuit is used to provide power and output signals, and includes power and signal output equipment. The power supply provides the voltage required by the respiration detector; the signal output device can output the physical sign data obtained by the respiration detector in a wired or wireless manner (such as Bluetooth or wifi signal or infrared).

[0055] The wearable device 3 may be a face mask, a watch, a bracelet, etc., and a breath detector is installed on the wearable device, which can conveniently detect ...

Embodiment 2

[0059] Using the ultra-light wearable breathing monitoring instrument prepared in Example 1, the breathing status can be monitored in real time through relevant response electrical parameters. The relevant response electrical parameters can be one or more of the direct parameters of response current, response voltage, resistance, resistivity, and impedance, or derived parameters obtained by direct parameter processing. In this embodiment, the response electrical parameters all adopt response Current.

[0060] The monitoring method of the ultra-light wearable respiratory monitoring instrument includes the following steps: placing the ultra-light wearable respiratory monitoring instrument in the environment to be tested, the respiratory detector absorbs or releases moisture to cause the conductivity to change, and The sensing circuit sends out an output signal, and according to the output signal, it monitors the number of breathing, frequency, pause, intensity, and the time ratio o...

Embodiment 3

[0069] The breathing detector described in Example 1 can be prepared according to the following method: mix the elastic conductive material and the flexible high molecular polymer in a volume ratio of 1:3~4:1; shape the mixture; heat the molded mixture to solidify , The curing temperature is 50~120℃, and the curing time is 1~12h. The elastic conductive colloid can be prepared in accordance with the Chinese patent application with the announcement number CN104558699A and the invention title "An elastic conductive colloid, preparation method and application". The flexible high molecular polymer can be polydimethylsiloxane, or polyolefin elastomer, or ethylene-vinyl acetate copolymer, or EPDM rubber.

[0070] The raw materials of the breathing detector can also be modified by adding inorganic materials. The breathing detector made by mixing inorganic materials, elastic conductive colloids and flexible high molecular polymers has an increased surface area, which can enhance its water...

Description

Technical field [0001] The invention belongs to the field of sensors, and particularly relates to an ultra-light wearable breathing monitoring instrument and a monitoring method thereof. Background technique [0002] Breathing is an important vital sign that helps to understand a person's overall health and sleep quality. Respiration rate and breathing pattern are also considered to reflect the basic health of individuals. As a kind of physiological parameter, respiratory rate is a sensitive indicator of acute respiratory dysfunction, and both doctors and nurses regard it as one of the vital signs. Therefore, the respiratory rate sensor is particularly important. The respiratory rate sensor can reflect the respiratory status in real time, record the number of breaths within a respiratory unit time and display the current respiratory rate. This can help doctors and researchers grasp the patient's condition in real time, and timely Make effective treatments to save the lives of p...
