Multi-cavity infusible drainage pipeline

Abstract

The invention discloses a multi-cavity infusion drainage pipeline that includes a guide needle, the guide needle connecting section, the cavity drainage section and the groove drainage section which are sequentially arranged in the threading direction; the tail end of the guide needle is connected with the head end of the guide needle connecting section, the guide needle connecting section and thecavity drainage section are integrally formed, the cavity drainage section and the groove drainage section are integrally formed, infusion cavities are formed in the tube walls of the cavity drainagesection and the groove drainage section, the cavity drainage section is further provided with a drainage cavity, and an infusion device is further included. The multi-cavity infusible drainage pipeline is simple in structure, convenient to machine, easy to operate and high in drainage efficiency; when a medical institution conducts effective drainage on effusion or inflammatory secreta in the body of a surgical patient, the closed channel is used for conveying medicine and feeding medicine or air to a focus, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-chamber infusion drainage tube. Background technique [0002] Drainage tubes are generally used after surgical operations, and are mainly used to guide pus, waste blood, and waste liquid accumulated in human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. At present, there are many kinds of drainage tubes used in clinical surgery, and most of them use polymer material tubes with various shapes of side holes and circular end holes. There are two common problems in the existing drainage tubes: 1. The holes are easy to be damaged. Human tissue fragments, physiological residues and blood clots are blocked, especially under negative pressure, the drainage is not smooth, the treatment effect is not good, and it is difficult to extubate after the end, which aggravates the suffering of patients and increase...

Problems solved by technology

At present, there are many kinds of drainage tubes used in clinical surgery, and most of them use polymer material tubes with various shapes of side holes and circular end holes. There are two common problems in the existing drainage tubes: 1. The holes are easy to be damaged. Human tissue fragments, physiological residues and blood clots are blocked, especially under negative pressure, the drainage is not smooth, the treatment effect is not good, and it is difficult to extubate after the end, which aggravates the suffering of patients and increases the labor intensity of medical staff; 2. Domestic general The drainage tube is open and easy to contaminate, and the puncture needle cannot be used to place the drainage tube. 3. The pressure in the human body is low after a long period of negative pressure drainage, resulting in a pressure difference between the body and the outside of the body that cannot meet the drainage requirements and affects the drainage effect; 4. Some patients need to administer drugs at the lesion site in the body. Most of the existing drainage tubes cannot realize this function, or the operation is cumbersome, which increases the burden on the medical staff and causes pain to the patients.
