Postoperative drainage device for thyroid and breast surgery

Abstract

The invention relates to a postoperative drainage device for the thyroid and breast surgery department. The problem that in the prior art, during postoperative drainage of a patient, many negative pressure machines need to be occupied or frequent manual operation of medical staff is needed is effectively solved. According to the technical scheme, the device can correspondingly control a rubber negative pressure ball to act according to changes of the negative pressure environment in a collecting bottle, so that the negative pressure environment in the collecting bottle is adjusted, and automatic adjustment of the air pressure environment in the collecting bottle is completed under the condition that a negative pressure machine and medical staff are not needed; the use of a negative pressure machine is reduced, and the complexity caused by repeated manual operation of medical staff frequently going to and out of each ward is also avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a drainage device after nail breast surgery. Background technique [0002] After thyroid breast surgery, drainage is usually performed on the affected part of the patient. The main function is to drain the blood, fluid, and gas in the deep or shallow parts of the body. The existing drainage is usually divided into passive drainage and active drainage. Passive drainage is mainly Through the gravity of the drainage object itself or the pressure of the drainage port, it flows from a high place to a low place, and then collects the effusion in the drainage bottle, which belongs to passive drainage. Active drainage uses the negative pressure principle in physics, mainly through drainage. The negative pressure generated by the ball itself absorbs the drainage material, so as to discharge the blood and fluid from the affected area out of the human body; [0003] Pas...

AI Technical Summary

Problems solved by technology

[0004] However, there are certain deficiencies in the above two situations. Either each patient needs to be equipped with a negative pressure machine and the negative pressure machine needs to be in working condition all the time (it takes up and consumes a lot of resources in the hospital), or the medical staff needs to be active and frequent. Manually control the air pressure environment in the drainage ball by going to and from each ward (enhancing the workload of medical staff);
