Novel PEEP valve based on electromagnetic control technology

Abstract

The invention belongs to the technical field of PEEP valves and discloses a novel PEEP valve based on an electromagnetic control technology. The novel PEEP valve comprises a valve body, a fixed seat is fixedly mounted on the wall surface of the upper bottom of the valve body, a valve seat is slidably connected in the fixed seat, an ejector pin sleeve is arranged in the fixed seat, an ejector pin is fixedly mounted in the ejector pin sleeve, a coil holder is arranged in the valve seat, a coil is wound on the side wall of the coil holder, a U-shaped cup is fixedly installed on the inner bottom wall face of the valve seat, and a magnet is magnetically attracted to the middle of the inner bottom wall face of the U-shaped cup. According to the novel PEEP valve, the magnetic field reaction is changed through the cooperation of a first capillary tube and a second capillary tube, precise control over different pressures can be completed with extremely low power consumption, gas consumption is not needed, pressure control is facilitated through electromagnetic control, the situation that the air pressure needs to be repeatedly adjusted when the air pressure is provided is avoided, the treatment efficiency is improved, the effect of improving the response speed is achieved through electromagnetic control, and the effect of saving cost is achieved while the effect is improved.

Description

technical field [0001] The invention relates to the technical field of PEEP valves, in particular to a novel PEEP valve based on electromagnetic control technology. Background technique [0002] Positive end-expiratory pressure (PEEP) is to maintain a certain positive pressure in the airway at the end of expiration when using a ventilator (usually only use positive pressure during inhalation, and the pressure drops to zero during exhalation) to avoid early alveolar closure, It expands some of the alveoli that have lost ventilation function due to exudation, atelectasis, etc., and increases the reduced functional residual capacity to achieve the purpose of increasing blood oxygen. PEEP is similar to intermittent positive pressure breathing, but because it takes longer to act, it has a greater impact on the respiratory and circulatory systems. Positive end-expiratory pressure (PEEP) can increase the functional residual capacity, make the alveoli less prone to trapping at the ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are existing PEEP valves for ventilators on the market. When ventilators use electronic PEEP valves, there will be a problem of slow response caused by complex control methods. , because of the instability of the air pressure, the air consumption of the existing PEEP valves on the market increases with the instability of the air pressure, resulting in excessive waste
