Abstract

The invention discloses a negative-pressure control valve, which comprises a valve core and a valve base, wherein the longitudinal section of the valve core is conical, trapezoidal or circular; the valve base is provided with a concave base which is matched with the valve core; a convex ring is arranged on the upper part of the valve core; a groove formed at a corresponding position on the valve base is locked with the convex ring on the valve core; the valve core is turned around the groove; the valve core and the valve base are provided with through holes; the diversion flow is determined by the coincidence area of two through holes; and the through hole on the valve base is communicated with a valve base connecting tube. A negative-drainage bottle adopting the negative-pressure control valve comprises a drainage bottle, a negative-pressure control valve and a drainage tube, wherein the drainage tube is connected with the negative-pressure control valve and the drainage bottle; and the drainage bottle is a vacuumized negative-pressure bottle.

Description

technical field [0001] The invention relates to a negative pressure control valve and a negative pressure drainage bottle used for drainage of operation wound or body cavity. Background technique [0002] There are many kinds of open materials in the prior art, which provide a negative pressure drainage device for surgical wound or body cavity drainage, such as CN201110321672.9 discloses a negative pressure drainage device, including a cylinder, a drainage tube, a piston plate, a piston Rod and bracket, the piston plate divides the inner cavity of the cylinder into a lower cavity and an upper cavity, the upper cavity communicates with the atmosphere, and a detachable liquid storage device is connected to the bottom of the lower cavity; the drain port of the drainage tube communicates with the lower cavity, and the drainage tube A valve is arranged on the upper side; a vent hole connecting the upper chamber and the lower chamber is arranged on the piston plate.
