Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and specifically discloses a pressure detection device for a breathing balloon safety valve. Background Technology

[0002] A breathing bag is an emergency artificial ventilation device, primarily used to assist patients' breathing during cardiopulmonary resuscitation or respiratory failure. Its core function is to deliver oxygen or air to the patient's lungs by manually squeezing the bag, while simultaneously forming a seal between the bag and the patient's face through a mask to ensure effective ventilation. A pressure safety valve is usually installed on the outer wall of the airway; when the delivered air pressure exceeds a set value (typically 40-60 cmH2O for adults, and even lower for children), the pressure automatically releases to prevent barotrauma to the patient's airway.

[0003] Existing breathing bags passively release excessive air pressure through pressure limiting valves (such as spring-loaded relief valves), which has the following drawbacks:

[0004] It cannot monitor pressure in real time, and can only release pressure when it is over-pressured. It cannot provide real-time airway pressure data, and medical staff cannot quantify and evaluate the ventilation effect.

[0005] The valve body is prone to aging or blockage and cannot provide timely warnings, making the malfunction highly concealed and posing a safety hazard. Utility Model Content

[0006] This invention proposes a pressure detection device for a breathing bag safety valve. The pressure gauge displays the pressure value in real time, and the piezoresistive sensor detects the airway pressure simultaneously. If the pressure exceeds a preset threshold, a buzzer and an LED warning light are immediately triggered to provide a dual warning of sound and light, ensuring that medical personnel can quickly identify abnormal high pressure during emergency treatment and significantly reducing the risk of barotrauma.

[0007] This invention is implemented as follows: a pressure detection device for a breathing balloon safety valve, comprising:

[0008] The three-way connector has a first end that is a mask interface end, a second end that is a balloon connection end, and a third end that is a detection airway.

[0009] A pressure detection module, comprising a pressure gauge and an electronic alarm, wherein the pressure gauge is connected to the detection air passage via a Bourdon tube, and the electronic alarm is fixedly installed on the outer wall of the detection air passage;

[0010] A safety regulating valve is located at the junction of the three-way connection body and the detection air passage.

[0011] As a preferred embodiment of the pressure detection device for a breathing balloon safety valve according to this utility model, the outer wall of the safety regulating valve is provided with a pressure relief port.

[0012] As a preferred embodiment of the pressure detection device for a breathing balloon safety valve according to this utility model, the outer wall of the three-way connecting body is fixedly connected to a connection port, and the detection air passage and the connection port are threadedly connected.

[0013] As a preferred embodiment of the pressure detection device for a breathing bag safety valve according to this utility model, the electronic alarm includes a piezoresistive sensor, a buzzer, and an LED warning light disposed on the inner side of the detection airway, and an adjustment button is provided on the outer wall of the electronic alarm.

[0014] As a preferred embodiment of the pressure detection device for a breathing balloon safety valve according to this utility model, the inner wall of the mask interface end is provided with a connecting internal thread, and the outer wall of the balloon connection end is fixedly connected with a convex ring.

[0015] As a preferred embodiment of the pressure detection device for a breathing bag safety valve according to this utility model, the end of the detection airway is an L-shaped bend, and the inner wall of the L-shaped bend is polished.

[0016] As a preferred embodiment of the pressure detection device for a breathing balloon safety valve according to this utility model, the pressure gauge is a mechanical pressure gauge with a scale range of 0-80cmH2O.

[0017] The beneficial effects of this utility model are:

[0018] The gas pressure in the airway is detected and transmitted to a mechanical pressure gauge through a Bourdon tube, which displays the pressure value in real time. A piezoresistive sensor detects the airway pressure simultaneously. If the pressure exceeds a preset threshold, the buzzer and LED warning light will be triggered immediately by setting the button, achieving a dual warning of sound and light. This ensures that medical staff can quickly identify abnormal high pressure (such as airway obstruction or hyperventilation) during emergency treatment, significantly reducing the risk of barotrauma.

[0019] The safety regulating valve is located at the junction of the three-way body and the detection airway. When the pressure continues to rise, the valve body is pushed open by the air pressure, and excess gas is discharged through the pressure relief port to avoid lung damage caused by excessive airway pressure. The pressure relief threshold can be adjusted by rotating the safety regulating valve to adapt to the lung compliance needs of different patients such as adults and children. The L-shaped bend at the end of the detection airway reduces airflow turbulence, and the polished inner wall reduces pressure loss to ensure the accuracy of the test data.

Simultaneously, some gas is diverted to the detection airway 4. The gas pressure in the detection airway 4 is transmitted to a mechanical pressure gauge 5 via a Bourdon tube 7, displaying the pressure value in real time.
