Abstract

The invention provides a PEEP (positive end expiratory pressure) valve and a respirator with the same. The PEEP valve comprises a throttling part and a gas controlling part, wherein the inlet end of the throttling part is connected with a dynamic gas source of the respirator; the inlet end of the gas controlling part is connected with the outlet end of the throttling part; the outlet end of the gas controlling part is connected with an exhalation valve; and the gas controlling part responds to the throttling amount of the throttling part to change the pressure applied to the exhalation valve to realize continuous adjustment of PEEP. According to the invention, the PEEP functions are integrated inside the respirator host via the mechanical PEEP valve, such as mechanical gas flow control, scale indication, digital display and closed-loop control, and the valve not only improves the reliability of PEEP realization and lowers the requirements for the hardware platform of the respirator, but also meets the clinical demands in terms of comfort and has simple design and low cost.

Description

technical field [0001] The invention relates to a PEEP (positive end expiratory pressure) valve, in particular to a built-in PEEP valve used in a ventilator used in the medical field. In addition, the present invention also relates to a ventilator with the PEEP valve. Background technique [0002] Ventilators have been widely used in medical treatment, and PEEP, as a special therapeutic function for ventilators, has special clinical significance. The ventilator uses the PEEP valve to keep the airway at a certain positive pressure during the expiratory phase, so that the function of PEEP is to expand and fix the alveoli, to prevent the small airway from collapsing early at the end of expiration, and to re-expand the collapsed alveoli. Increasing alveolar volume can also increase the contact area between alveoli and microvessels to increase diffusion and oxygenation, improve uneven ventilation and perfusion, and redistribute water in the lungs (excessive water will reduce gas...
