Description

Physiological detection system

The present invention relates to medical assistance systems, and more particularly to a physiological detection system that utilizes a respiratory state.

In medical assistance systems, respiratory devices are primarily used to provide patients with insufficient lung function to achieve adequate gas exchange, such as patients with chronic lung disease, or asthma patients. The conventional breathing apparatus comprises a cover and a respirator connected to the mask by a gas supply pipe, the mask is used to cover the mouth and nose of the patient, and the respirator can provide oxygen or air into the mask to make oxygen or air. Enter the lungs of the patient.

Some patients who use breathing apparatus will suddenly have respiratory instability and even symptoms of respiratory arrest, but there may not be medical staff next to them, especially when the patient sleeps at night. Although the conventional breathing apparatus can sense the breathing state of the patient, including flow pressure or related breathing parameters, the sensing point is mainly set inside the respirator, and the breathing state of the patient needs to be felt through the air supply tube. It is measured, so there is not only the shortcoming of detecting the reaction time delay, but also the piezoresistive phenomenon caused by the gas passing through the air supply pipe reduces the detection accuracy of the breathing device.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a physiological detection system for quickly and accurately detecting a user's breathing condition, thereby evaluating and diagnosing whether a user has a respiratory abnormality.

In order to achieve the above objective, the physiological detection system provided by the present invention comprises a mask for a user to wear, a processing unit, a first transmission unit, and a sensor disposed on the mask. The sensor is configured to sense a gas state in the mask, and generate a sensing signal according to the gas state to be transmitted to the processing unit by the first transmission unit.

The gas state in the present invention may be the temperature, humidity, flow rate, pressure or carbon dioxide content of the gas. The temperature, humidity, flow rate, pressure and carbon dioxide content of the gas in the mask change due to the user exhaling and inhaling. The sensor is relatively close to the user's mouth and nose due to the mask. The sensing unit senses the change of the user's breathing, so the processing unit can use the sensing signal to quickly and accurately calculate the breathing condition of the user, such as the frequency of the breathing frequency or the amplitude and the period of the amplitude, etc., thereby evaluating and diagnosing the user's breathing. Is there an abnormality, such as a sudden or slow breathing, or a pause in breathing?

Another object of the present invention is to provide a physiological detection system that can supply gas to a user and can change the air supply condition according to the breathing condition of the user.

In order to achieve the above object, the physiological detection system provided by the present invention may further include a respirator connected to the mask by an air supply tube for supplying gas into the mask. Thereby, the processing unit can further control the respirator such that the respirator adjusts the air supply condition according to the breathing condition of the user to help the user resume normal breathing.

The Applicant first describes the same or similar elements or structural features thereof in the embodiments and the drawings which will be described below.

Referring to the first to third figures, a physiological detection system 10 according to a first preferred embodiment of the present invention includes a cover 20, a sensor 40, a first transmission unit 50, and a processing device. 60.

The mask 20 is for a user to wear and covers the mouth and nose of the user. The sensor 40 is disposed on the mask 20 for sensing a gas state in the mask 20, such as temperature, humidity, flow, pressure or carbon dioxide content of the gas, and transmitting a sensing signal by the first transmission Unit 50 is transmitted to one of processing units 62 of processing device 60.

When the user exhales and inhales, the temperature, humidity, flow rate, pressure, and carbon dioxide content of the gas in the mask 20 are changed. Therefore, the processing unit 62 can use the sensing signal to calculate the breathing state of the user. For example, respiratory rate or strength and so on. The processing device 60 can store the parameters calculated by the processing unit 62 for the medical staff to evaluate and diagnose whether the user's breathing has an abnormality, such as a rapid or slow breathing change, or a pause in breathing, and the like. Alternatively, the processing device 60 may upload the parameters calculated by the processing unit 62 to the analysis software, and may also evaluate and diagnose whether the user's breathing has an abnormality.

As shown in the first figure, in the embodiment, the first transmission unit 50 transmits the sensing signal in a wireless manner. However, the first transmission unit 50 can also transmit the sensing signal in a wired manner (eg, The fourth picture shows). In addition, the processing device 60 can be a notebook computer, a smart phone, a flash drive, etc., in addition to a notebook computer.

As shown in the fourth embodiment, the physiological detection system 10 according to a second preferred embodiment of the present invention further includes a respirator 70 connected to the mask 20 by an air supply tube 72 for supplying Oxygen or air is introduced into the mask 20. Thereby, the parameter calculated by the processing unit 62 can be used to feedback the respirator 70 so that the respirator 70 adjusts the air supply condition according to the breathing condition of the user to help the user resume normal breathing.

As shown in the fifth figure, in the embodiment, the processing unit 60 transmits one of the sensing parameters to the control unit 74 of the respirator 70 by a second transmission unit 80 to control the The air supply status of the respirator 70. The second transmission unit 80 can be a wired or wireless transmission unit.

As shown in the sixth embodiment, in the physiological detection system 10 according to a third preferred embodiment of the present invention, the respirator 70 has a processing unit 76 in addition to the control unit 74, and thus, the The physiological detection system 10 may not include the processing device 60 and the second transmission unit 80. The sensor 40 transmits the sensing signal to the processing unit 76 by the first transmission unit 50, and the processing unit 76 A sensing parameter is calculated by the sensing signal for the control unit 74 to control the air supply condition of the respirator 70.

In the physiological detection system 10 provided by the present invention, since the sensor 40 is disposed on the mask 20 and is relatively close to the mouth and nose of the user, the change of the user's breathing can be detected quite directly, so the physiological detection The measurement system 10 can quickly and accurately detect the breathing condition of the user. Moreover, the physiological detection system 10 has a function of detecting breathing even if the respirator 70 is not included, and can be used as a simple respiratory state detection and diagnosis tool for home monitoring.
