Continuous negative pressure drainage device for orthopedic internal fixation operation

Abstract

The invention discloses a continuous negative pressure drainage device for an orthopedic internal fixation operation. The continuous negative pressure drainage device comprises a supporting assembly,a drainage assembly and a dredging assembly, wherein the supporting assembly is located at the lowermost portion of the continuous negative pressure drainage device; the drainage assembly is arrangedabove the supporting assembly; and the dredging assembly is arranged on the drainage assembly. The continuous negative pressure drainage device is scientific and reasonable and is safe and convenientto use; the device can be carried out without any human operation in the whole process; blockages in a drainage tube are dredged by utilizing a pressurization method of superposition and centralized release of normal negative pressure suction force, so that a surgical patient does not need to pay attention to observation all the time to avoid the phenomenon of blockage of the drainage tube; a large-flow one-way valve main body, a blocking ball moving groove, a blocking ball and a flow channel are designed, and a one-way valve in the prior art is not adopted, so that it is guaranteed that lumpscannot block the one-way valve in a drainage process, and the design is not prone to causing blocking; and multiple drainage bottles are designed to communicate with one another, and when one drainage bottle is full, the empty drainage bottle does not need to be replaced immediately, so that the use continuity of the device is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a continuous negative pressure drainage device for orthopedic internal fixation. Background technique [0002] In the existing medical technology means, pus and blood and other filth will continue to flow out of the patient's wound after the operation. In order to clean up the filth and prevent the patient's wound infection, a negative pressure drainage device was born, but the negative pressure in the prior art The drainage device requires medical staff and patients to always pay attention to whether the drainage bottle is full and needs to be replaced, and the drainage tube is easily blocked by blood clots and other lumps. During thoracic surgery, the patient can squeeze out the blockage by coughing to restore the drainage effect of the drainage device , but the drainage after orthopedic internal fixation and other operations cannot be timely and effectively cleaned up the blo...

Problems solved by technology

[0002] In the existing medical technology means, pus and blood and other filth will continue to flow out of the patient's wound after the operation. In order to clean up the filth and prevent the patient's wound infection, a negative pressure drainage device was born, but the negative pressure in the prior art The drainage device requires medical staff and patients to always pay attention to whether the drainage bottle is full and needs to be replaced, and the drainage tube is easily blocked by blood clots and other lumps. During thoracic surgery, the patient can squeeze out the blockage by coughing to restore the drainage effect of the drainage device , but the drainage after orthopedic internal fixation and other operations cannot be timely and effectively cleaned up the blockage, the general drainage time is 1-3 days, because the time is long, if the drainage tube is blocked for a long time, and no one finds it Under normal circumstances, it is extremely unfavorable to the recovery of the patient's wound, and if no one finds that the drainage bottle is full, it will also affect the normal drainage and the surrounding environment. Therefore, people need a continuous negative pressure drainage device for orthopedic internal fixation to solve the problem. above question
