Adjustable negative pressure drainage and flushing set

Abstract

The invention discloses an adjustable negative pressure drainage and flushing set. The set comprises a drainage cylinder, an anti-skid unit, a flushing unit, a drainage unit, a flushing fluid supply unit and an exhaust unit. The drainage cylinder: the middle of the lower end of the drainage cylinder is in threaded connection with a screw rod, the upper end of the screw rod is connected to a leather cushion piston, the leather cushion piston and the interior of the drainage cylinder are installed in a matching mode, the middle of the upper end of the drainage cylinder communicates with an interface, and a three-way device is arranged at the upper end of the drainage cylinder; the anti-skid unit: the anti-skid unit is located at the lower end of the screw rod; the flushing unit: the flushingunit is located at the right end of the three-way device; the drainage unit: the drainage unit is located at the upper end of the three-way device; and the flushing fluid supply unit: the flushing fluid supply unit is located at the left end of the three-way device. The set not only can provide fixed negative pressure suction, but also can control the magnitude of the provided negative pressure,and can realize the flushing function on the premise of ensuring the drainage function.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable negative pressure drainage and flushing set. Background technique [0002] In the field of medical technology, for patients, the drainage of effusion and the cleaning of the injured part are indispensable parts of medical care, but the current drainage device has certain defects. On the one hand, the existing clinical drainage device, although It can provide fixed negative pressure suction, not only can adjust the negative pressure according to clinical needs, but on the other hand, most of the current clinical application drainage structures are purely negative pressure drainage, which cannot improve the flushing function, and at the same time, the operation is complicated, which limits the wide application of the product. Therefore, we propose an adjustable negative pressure drainage and irrigation suit. Contents of the invention [0003] The technical ...
