Gasbag pressure measurement connects

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an air sac pressure measuring joint.

The insertion of an endotracheal tube through an oral/nasal endotracheal tube or a tracheotomy to establish an artificial airway is a prerequisite for ensuring smooth progress of invasive mechanical ventilation treatment, and the safety management of an endotracheal tube balloon is an important link for the care of the artificial airway. The air bag is reasonably inflated to seal the airway, fix the catheter and ensure the tidal volume, and can also prevent oropharynx secretion from entering the lower respiratory tract and prevent aspiration, thereby reducing pulmonary infection.

The ideal air sac pressure can prevent air leakage between the air sac and the tracheal wall and avoid the air sac from pressing the tracheal wall to cause ischemia and necrosis. The mechanical ventilation guideline of the medical science of the China medical society of serious illness suggests that the pressure of an air sac is detected 3 times a day, and the pressure in the air sac of an artificial trachea cannula is kept between 25 and 30cmH ₂ O can effectively seal the airway and is not higher than the capillary osmotic pressure of the mucous membrane of the inner wall of the trachea.

There are a variety of balloon measurement methods in the clinic, most commonly using hand-held balloon pressure gauges (CPM) measurements. The inflating interface of the trachea cannula air bag is connected with an air bag pressure gauge inflating valve. The balloon was slowly squeezed under manometer test to gradually inflate until the balloon pressure reached 25cmH2O-30cmH2O.

(2) When the air bag pressure gauge is removed, air leakage and pressure reduction are generated, so that 2-3cm H2O of air leakage is generated when the pressure measuring pipe is separated, the air leakage is compensated by +2cmH2O on an ideal pressure value, and the air leakage is also required to be calibrated periodically;

(3) In addition, often many patients clinically share a balloon pressure monitor, increasing the risk of cross-infection.

The using method comprises the following steps:

step 1: when the pressure measuring device is used for the first time, the valves 6 arranged on the first interface 2 and the second interface 3 are in a closed state, the first interface 2 is connected with the joint of the trachea cannula air bag, and the trachea cannula air bag is communicated with the pressure measuring joint;

step 2: the injector or the air bag pressure gauge is connected with the second interface 3 by pumping back about 10ml of air, a valve 6 arranged on the second interface 3 is opened, and the air is injected, so that the numerical value on the pressure gauge 5 is about 30cmH 2O;

step 3: opening a valve 6 arranged on the first interface 2 to enable the trachea cannula air sac to be communicated with the pressure measuring joint, observing the numerical change of the pressure gauge 5 and reading;

step 4: pushing or sucking the syringe or the balloon pressure gauge to maintain the pressure gauge 5 value between 25cmH2O and 30cmH 2O;

step 5: the valve 6 provided on the second port 3 is closed and the syringe or the balloon pressure gauge is withdrawn.

In addition, when the trachea cannula air bag leaks, the injector or the air bag pressure gauge can be plugged again, the valve 6 arranged on the second interface 3 is opened, and the air is supplemented to a certain extent through the injector or the air bag pressure gauge.

After the inflation equipment can be guaranteed to be disconnected in the use process of the pressure measuring connector, the air leakage phenomenon can not occur to the air bag pressure, the condition of different air leakage caused by different user manipulation problems can not occur, the measuring accuracy and consistency are guaranteed, and meanwhile, the pressure meter 5 can continuously observe the change of the pressure in the air bag of the tracheal intubation.
