Combined negative pressure drainage device

Abstract

The invention discloses a combined negative pressure drainage device. The device comprises a plurality of drainage bottle components which are sequentially connected in series, wherein each drainage bottle component comprises a cover body, a negative pressure drainage bag and a jacket bottle; a drainage tube is connected to a drainage tube joint of the drainage bottle component at the front end of the drainage bottle components connected in series, and a drainage joint is connected to the other end of the drainage tube; a negative pressure tube is connected to a negative pressure tube joint of the drainage bottle component at the tail end of the drainage bottle components connected in series, and the other end of the negative pressure tube is connected with a pressure control valve which is connected with a negative pressure device through a negative pressure device connecting tube. According to the combined negative pressure drainage device, the drainage bottle components are connected in series, so that the drainage capacity is improved; negative pressure suction force is provided by the negative pressure device, so that a better drainage effect is achieved, and pressure differences between the negative pressure drainage bags and the jacket bottles can be kept stable; the jacket bottles can be used for many times, so that the practicability of the whole device is improved.

Description

technical field [0001] The invention relates to a drainage device, specifically a negative pressure drainage combination device with large capacity, avoiding infection and high practicability, which belongs to the technical field of medical devices. Background technique [0002] Negative pressure drainage devices are widely used in the medical field. The general drainage devices are separate drainage bags, drainage bottles, etc., and the drainage capacity is small, and these drainage devices generally rely on the negative pressure attraction generated by the treatment of the drainage container in advance. The pressure suction effect is poor, reflux infection is prone to occur, and the drainage container is easily damaged during use, causing leakage and pollution, which is very inconvenient to operate. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a negative pressure drainage combined ...
