Technical Field

The application relates to the technical field of medical instruments, in particular to a plunger type air bag pressure monitoring device.

Background

In clinical application, for avoiding oropharynx secretion, stomach content mistake income air flue, prevent that gaseous by the palirrhea condition of upper respiratory tract etc. from taking place, need set up the gasbag between artifical air flue and patient's air flue to guarantee effective air volume. When the artificial airway and the air bag are used for ventilation, in order to prevent air leakage of the air bag and injury of airway mucosa, the pressure of the air bag on the artificial airway needs to be monitored and managed.

The existing air bag pressure monitor mainly comprises: a hand-held pressure gauge with a pressure gauge and an automatic adjusting air pump type pressure monitor. Specifically, for monitoring the pressure of the air bag, patent CN214426888U proposes that a handheld pressure gauge uses a spring tube mechanical pointer type pressure gauge to perform pressure detection without battery power supply; patents CN214209099U and CN209500465U propose pressure sensors for pressure detection and display on a display screen with numerical values, and the device needs to be powered.

For the adjustment of the pressure of the air bag, for example, a pressure gauge held by a patent CN214426888U is pressurized by squeezing a rubber handle with a one-way valve, and is decompressed by pressing a decompression button, so that the automatic adjustment of the pressure of the air bag cannot be realized; the CN214209099U patent realizes the pressure rise and fall by using an inflator pump and an electromagnetic valve, and the CN209500465U patent realizes the pressure rise and fall by using the inflator pump, both of which can realize the automatic regulation of the air bag pressure. When the inflator pump and the electromagnetic valve are combined, the electromagnetic valve needs to be opened and closed for air release by controlling the electromagnetic valve, due to the difference of the quality of the electromagnetic valve, the control of the air displacement is not accurate, the risk of VAP is increased due to excessive air exhaust of the electromagnetic valve, the working frequency of the inflator pump is increased, and the service life of the inflator pump is shortened. When the pressure of the air bag is automatically adjusted by using the charging pump, the target pressure does not exceed 30cmH usually ₂ And O, in the pressure state, the inflation and suction pump needs to continuously adjust the inflation and suction state to reach the set pressure, and the precision is reduced and the service life is shortened due to frequent rotation of the motor.

The indication and alarm aiming at the continuous monitoring of the pressure of the air bag, such as a handheld pressure measuring meter uses a dial plate with a color mark to visually prompt and warn the pressure; the patent CN209500465U uses a warning lamp to prompt information. In the process of continuously monitoring the pressure of the air bag, a patient is possibly in a coma or sleep state, only alarm information is prompted through a dial plate with a color mark or an alarm lamp, medical workers cannot find and handle the alarm information immediately, and therefore the risk of increasing VAP of the patient due to delay in treatment is possibly caused.
