Thoracic surgery drainage tube

Abstract

A thoracic surgery drainage tube is disclosed. In the prior art, a drainage tube with good overall rigidity is not convenient to bend and fix and great pain is brought to a patient in the treatment process, and once a liquid inlet hole at the highest position of the drainage tube is exposed out of the exudate level, the whole drainage tube is out of action. The above problem is solved by the application of the thoracic surgery drainage tube. The thoracic surgery drainage tube comprises a negative pressure drainage tube formed by a soft drainage tube body, and is characterized in that a plurality of metal wire rings which are arranged in a linear array along the extension direction of the tube body are arranged on the drainage tube wall of the drainage tube body; a lateral suction head is arranged at the front end of the drainage tube body of the negative pressure drainage tube; and a drainage box connecting part is arranged at the rear end of the drainage tube body. The thoracic surgery drainage tube of the invention has advantages of reasonable design, compact structure, high radial strength, good axial flexibility, large capillary force for liquid suction, wide liquid suction range, small pain feeling of patients and short drainage time, and is beneficial to rapid postoperative recovery.

Description

technical field [0001] The invention belongs to the technical field of medical drainage tubes, and in particular relates to a thoracic surgery with high radial strength, good axial softness, large capillary force for absorbing liquid, wide liquid absorbing range, less pain to the patient, and conducive to rapid postoperative recovery Drainage tube. Background technique [0002] After thoracic surgery, the complete elimination of pleural exudate and pneumatosis is one of the most important treatment methods in thoracic surgery. Since the respiratory function of the lungs is realized under the negative pressure environment formed by the expansion and contraction of the thorax, the drainage after chest surgery is all closed drainage under negative pressure conditions. In order to prevent the drainage tube from being crushed by the internal and external pressure difference or the patient turning over on the hospital bed, the drainage tube needs to have a certain rigidity; pati...

In addition, for the purpose of allowing the drainage tube to drain fluid and gas in the pleural cavity in a wider range, multiple liquid inlet holes are usually set at the suction end of the drainage tube; however, the disadvantage of this approach is that once the drainage tube When the liquid inlet hole at the highest position on the top is exposed beyond the seepage liquid level, the entire drainage tube will lose its function
