Active closed drainage mechanism for thoracic and abdominal cavity surgery

Abstract

The invention discloses an active closed drainage mechanism for thoracic and abdominal cavity surgery, and particularly relates to the field of medical treatment. The active closed drainage mechanismcomprises a drainage storage bag, a portable hanging rope, a drainage needle tube and an active drainage device; a driving mechanism is fixedly installed on the surface of the active drainage device,and the top face of the drainage storage bag and the bottom face of the active drainage device are detachably installed; the liquid inlet end of the active drainage device is connected with one end ofthe drainage needle tube, the drainage storage bag comprises a liquid storage bag body, a release valve tube is arranged at the bottom end of the liquid storage bag body, an installation plate is arranged on the top face of the liquid storage bag body, and a liquid inlet tube opening is formed in the surface of the installation plate. According to the scheme, the medical drainage mechanism adoptsan active drainage mode, the active drainage device is controlled to work through transmission driving of the driving mechanism, and exudation, hydrops and the like in the body of a patient or in thedeep part of a local operation are guided out of the body through peristaltic pumping; bacteria urine infection and other postoperative risks caused by long-time retention of liquid such as hydrops in the body of a patient are avoided, and the practicability of the drainage mechanism is improved.

Description

technical field [0001] The invention relates to the field of medical technology, and more specifically, the invention is an active sealing drainage mechanism for thoracoabdominal surgery. Background technique [0002] Drainage bag is a commonly used post-operative care tool, especially for wounds in the abdominal cavity and thoracic cavity that cannot be closed due to high internal pressure, or the wound surface formed by skin ulceration. When dealing with the above problems, domestic medical institutions generally use gauze to lay on wounds that cannot be closed. Pleural effusions are often caused by pathogenic bacteria such as bacteria (tuberculosis is the most common), fungi, parasites, mycoplasma and viruses. Tuberculous exudative pleurisy, tuberculous empyema and other diseases, and metastatic cancer caused by the pleura itself (primary) or pleural metastasis (secondary) of malignant tumors in other parts. In addition, in connective tissue diseases such as systemic Sex...

[0002] Drainage bag is a commonly used post-operative care tool, especially for wounds in the abdominal cavity and thoracic cavity that cannot be closed due to high internal pressure, or the wound surface formed by skin ulceration. When dealing with the above problems, domestic medical institutions generally use gauze to lay on wounds that cannot be closed. Pleural effusions are often caused by pathogenic bacteria such as bacteria (tuberculosis is the most common), fungi, parasites, mycoplasma and viruses. Tuberculous exudative pleurisy, tuberculous empyema and other diseases, and metastatic cancer caused by the pleura itself (primary) or pleural metastasis (secondary) of malignant tumors in other parts. In addition, in connective tissue diseases such as systemic Lupus erythematosus, rheumatoid arthritis, etc. may also be accompanied by pleural effusion, which can easily lead to large-scale overflow of exudate, which in turn leads to skin infection and aggravates wound ulceration

[0003] The existing thoracoabdominal surgical drainage mechanism mainly consists of a drainage needle tube and a drainage bag. The drainage needle tube is mainly used to penetrate the wound inside the abdominal cavity and thorax of the human body. Drainage and drainage of fluids such as effusion and oozing blood to prevent secondary damage to the human body caused by effusion in the chest and abdomen. However, the existing drainage mechanism adopts positive pressure drainage without active drainage, and the drainage efficiency is low. Long-term storage in the human body leads to infection of the patient's wound

[0004] In addition, clinically, thoracentesis is often used to perform intermittent drainage for patients with a large amount of pleural effusion. The existing surgical drainage mechanism does not have the automatic detection function of the pleural effusion, which makes it impossible for medical staff to judge the pleural effusion after the operation. Due to the effusion situation, it is impossible to discharge the effusion in time. After thoracentesis, another catheter is fixed for continuous drainage, which makes the patient in pain for a long time; Due to the change of pressure, the traditional drainage mechanism has no protective function against sucking back, and it is easy to cause the liquid that has entered the drainage bag to flow back into the body, resulting in secondary infection of the wound in the patient's body, and may lead to the death of the patient in severe cases, which has certain defects
