Problems solved by technology

At present, there is no special tool to solve the above problems. Medical personnel generally use disposable scalp needles and disposable syringes to make their own tools in clinical operations. The disadvantage of self-made tools is that it is troublesome to obtain materials, and they can only be used after artificial processing. It is time-consuming, has low work efficiency, and prolongs the operation time of patients. In addition, there are hidden dangers of unstable negative pressure effect and unreliable fixed point fixation.

Abstract

The invention discloses an injection type negative pressure drainage device and belongs to medical equipment. The injection type negative pressure drainage device comprises a cylindrical casing, wherein one end of the cylindrical casing is connected with a drainage pipe, and both the cylindrical casing and the drainage pipe are transparent. A piston mandrel is arranged in the cylindrical casing, a fixing rod is arranged on one side of the piston mandrel, and the fixing rod and the piston mandrel are in detachable connection through a cloth adhesive tape. A plurality of side holes are formed on the side wall at the tail end of the drainage pipe. The injection type negative pressure drainage device is a disposable plastic device, all parts except the cloth adhesive tape are made of medical disposable plastic materials and are low in cost, easy to replace during use and reliable in fixing, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an injection type negative pressure drainage device. Background technique [0002] In clinical orthopedic surgery, a simple negative pressure device is needed to achieve the purpose of draining the accumulated blood and fluid from the surgical site. At present, there is no special tool to solve the above problems. Medical personnel generally use disposable scalp needles and disposable syringes to make their own tools in clinical operations. The disadvantage of self-made tools is that it is troublesome to obtain materials, and they can only be used after artificial processing. It is more time-consuming, has low work efficiency, and prolongs the operation time of the patient. In addition, there are hidden dangers of unstable negative pressure effect and unreliable fixed point fixation. Therefore, a dedicated tool is needed to solve the above problems.
