Abstract

The invention provides a positive expiratory end pressure (PEEP) valve and an anesthesia machine with the same. The PEEP valve comprises a first module (1), a second module (2), a valve core (6), a valve core mounting groove (21) and a first air passage (23), wherein a gas pipeline is arranged in the first module (1); the second module (2) is buckled with the first module (1); the valve core (6) is movably arranged in the cavity of the first module (1) and provided with a rolling film (5); the valve core mounting groove (21) is formed in one side of the second module (2) facing the first module (1) and corresponds to the valve core (6); and the first air passage (23) is formed in the second module (2) and used for communicating the valve core mounting groove (21) to a control gas source. Compared with the prior art, the PEEP valve has the advantage of simplicity in structure and installation.

Description

technical field [0001] The invention relates to the field of air control valves, in particular to a PEEP valve and an anesthesia machine with the PEEP valve. Background technique [0002] The PEEP valve (Positive Expiratory End Pressure) is a common device for ventilators and anesthesia machines, and it is installed in the circuit manifold. With the help of the PEEP valve, the anesthesia machine or ventilator can effectively control the patient's positive end-expiratory pressure. [0003] figure 1 It shows an exploded view of a PEEP valve in the prior art, which includes a valve body 3', a valve core assembly and a valve cover 7', wherein the valve core assembly consists of a diaphragm 4', a rolling film 5' and a 4' and the valve core 6' of the rolling film 5', the diaphragm 4' is stuck on the outside of the lower plate 61' of the valve core 6', and the curved part of the rolling film 5' is accommodated on the valve core upper plate 62' and in the groove 63' between the l...
