Embodiment 2

[0062] The airbag pressure management device provided by Embodiment 2 of the present invention differs from Embodiment 1 in that another airbag interface structure is adopted, and the specific differences are as follows:

[0063] combine Figure 7 and Figure 8 As shown, the sleeve 11 can be made of rubber material, and its exhaust end is sleeved on the outer wall of the intake end of the first valve body 32, and is connected with the intake end of the first valve body 32 with an interference fit. The air inlet end of 11 is thicker than the exhaust end of sleeve pipe 11, and forms first annular gap 19 between the air inlet end of first valve body 32; There is a second annular gap 18 between the insertion portion and the outer wall of the top cover, and the annular insertion portion is inserted into the first annular gap 19 , thereby making the connection between the push rod 13 and the sleeve 11 tighter. At the exhaust end of the airbag interface, the end face of the push ro...

Embodiment 3

[0065] The airbag pressure management device provided by Embodiment 3 of the present invention differs from Embodiment 2 in that another airbag interface structure is adopted, and the specific differences are as follows:

[0066] Such as Figure 9 As shown, the inner wall of the exhaust end of the sleeve 11 is provided with a rubber layer 111, and the exhaust end of the sleeve 11 forms an interference fit connection with the intake end of the first valve body 32 through the rubber layer 111: the rubber layer 111 of the second embodiment The contact between the layer and the intake end of the first valve body 32 is surface contact, and the contact between the rubber layer in the structure of this embodiment and the intake end of the first valve body is line contact, so the structure of this embodiment is more convenient than the second embodiment when installing. , the method of use is the same as in Example 2

Abstract

The invention relates to the field of medical instruments, and provides an airbag pressure management device. The device comprises an airbag interface and an inflation interface which are communicated through a connecting pipe; the inflation interface and an inflation device can be connected in an on-off cooperation mode, and the airbag interface and an airbag inflation valve can be connected in an on-off cooperation mode; the connecting pipe is provided with a pressure monitoring module. Due to the fact that the airbag interface and the inflation interface of the device both can achieve an on-off function on the condition that it is guaranteed that an airbag does no leak air in the state that the airbag inflation valve and the inflation device are connected, the device not only can monitor the pressure of the airbag and supplement air at any time but also can ensure leakproofness of the device in the monitoring and air supplementing process, the monitoring process is simple and efficient, and the air leakage phenomenon cannot occur; the pressure monitoring module can adopt parts such as a pressure sensor, and therefore a more accurate and more reliable monitoring result is achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, and in particular provides an airbag pressure management device. Background technique [0002] During invasive mechanical ventilation, the role of the air bag of the tracheal intubation (oral intubation and tracheotomy intubation) includes fixing the position of the tracheal intubation, sealing the airway, and preventing air leakage and aspiration. The ideal pressure in the air bag is required to block the air leakage between the endotracheal tube and the airway without affecting the blood circulation of the tracheal mucosa. Therefore, reasonable balloon pressure management plays a very important role in clinical care. [0003] Clinically, in order to ensure that the air sac pressure remains within a reasonable range, it is common practice to require an air sac pressure test every 4 hours. When the pressure is lower than the lower limit of the reasonable pressure value, the inflation operation ...
