Problems solved by technology

[0005] In the existing safety valve, a large part of the gas in the spontaneous breathing airway will be released directly into the whole machine, and is not guided to the outside of the whole machine, causing pollution to other parts in the machine, breeding bacteria, and causing crossover between different patients Infect
However, the existing safety valve is an integral structure. To clean the safety valve, the whole machine must be disassembled, which also increases the difficulty of sterilizing the safety valve.

Embodiment 1

[0037] This embodiment provides a safety valve.

[0038] Please refer to figure 1 and 3 , the safety valve includes a base 1 , an electromagnet 2 and a quick release assembly 100 .

[0039] The quick release assembly 100 includes a valve body 3 , an opening and closing member 4 , a screw cap 5 and a one-way valve 6 .

[0040] The base 1 is used to be fixed on the frame of the ventilator as the base of the entire safety valve, and plays a role of restraining other components of the safety valve. It is not in contact with any breathing gas, and only serves as a fixed support for the quick release assembly 100 .

[0041] In this embodiment, the base 1 has an installation cavity 11 through which two sides pass through. The base 1 can be fixed on the frame by means of threaded connection, screw fastening or clamping.

[0042] The electromagnet 2 is fixed on the base 1, such as figure 2 As shown, it can be fixed on the base 1 by means of screw locking. The position of the el...

Embodiment 2

[0075] Please refer to Figure 11 , the second embodiment provides a safety valve.

[0076] The difference between the safety valve and the first embodiment is that the quick release assembly 100 in the second embodiment includes an independent pipe 8 fixed on the valve body 3 and one end of which extends out of the safety valve.

[0077] When the diaphragm 42 is not deformed, the self-breathing port 32 is in sealing communication with the independent pipe 8 , which can be realized by, for example, adding a sealing member at the connection.

[0078] The independent pipeline 8 can communicate the main airway 31 with the external environment, that is, in the second embodiment, the autonomous breathing port 32 communicates with the independent pipeline 8 to form a complete autonomous breathing airway. The sealing of the spontaneous breathing airway is realized by adding a sealing member (such as a sealing ring) at the connection.

Embodiment 3

[0080] This embodiment provides a safety valve, which includes a base and a quick release assembly 100, wherein the base is installed on the frame of the breathing apparatus, and the quick release assembly 100 is detachably installed on the base, wherein the quick release assembly 100 is integrated There is an airway for communication between the patient's respiratory system and the flow control system.

[0081] In this embodiment, the integrated air passage of the safety valve quick release assembly 100 includes a main air passage, and the main air passage includes an air intake end;

[0082] A one-way valve may be provided at the inlet end of the main airway.

Abstract

The invention discloses a safety valve and a breathing apparatus. The safety valve comprises a base, a driving part and a quick release assembly, wherein the quick release assembly comprises a main airway, an autonomous breathing airway and an opening and closing part, wherein the autonomous breathing airway extends to the outside of the safety valve in a sealed manner and is communicated with an external environment; the main airway and the autonomous breathing airway are both arranged on the quick release assembly, so that airflow is isolated from the base and the driving part and is completely not contacted with the base and the driving part, and the condition that air in the autonomous breathing airway moves to the base, the driving part or other parts in the breathing apparatus and pollutes the parts is reduced or completely eliminated. Furthermore, the quick release assembly taken as a part, directly contacted with air, in the safety valve can be dismounted from the base conveniently, and is disinfected and sterilized independently and easily.

Description

technical field [0001] The application relates to a medical device, especially a ventilator and a safety valve thereof. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. [0003] Safety valves are a common component of ventilators. It belongs to the pressure control valve assembly, which can be directly used as the inhalation inlet of the patient, and also has the function of pressure protection of the gas circuit system. The safety valve is usually located near the patient's inspiratory end in the air circuit system of the ventilator. Its upstream is connected to the inspiratory flow control system, and its downstream is directly used as the gas output port of the whole machine (that is, the patient's inspiratory port) to connect with respiratory equipment, such as breat...
