Nursing drainage device for thoracic surgery department

Abstract

The invention relates to a nursing drainage device for the thoracic surgery department. The device comprises a puncturing needle, the tail end of the puncturing needle penetrates through an adhesive piece and extends into an upper liquid collection chamber, an outlet end of the upper liquid collection chamber is provided with an upper biological nano-membrane, the whole upper liquid collection chamber is sleeved with a lower liquid collection chamber, and an outlet end of the lower liquid collection chamber is provided with a lower biological nano-membrane and connected with a drainage tube; the drainage tube comprises an upper drainage tube body and a lower drainage tube body which are communicated with each other through a rubber hose, the upper drainage tube body is provided with a one-way valve, the lower drainage tube body is provided with a fixing device, a negative pressure air-suction device and a flow meter, and the tail end of the lower drainage tube body is communicated witha drainage bag. By means of the nursing drainage device, the situations that infection occurs in the thoracic cavity and liquid flows back can be avoided, and the device is convenient to fix, easy tooperate and capable of filtering liquid in the thoracic cavity and not polluting the environment; the biological nano-membranes replace water seal and valves, so that the device is convenient to carry and good in use effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a nursing drainage device for thoracic surgery. Background technique [0002] After thoracic surgery patients undergo surgery, a drainage tube needs to be inserted into the chest cavity to drain pus and some tissue fluid from the patient's body. The drainage device is to put one end of the drainage tube into the chest cavity, and the other end is connected to a lower place Seal the bottle with water to expel gas or collect fluid in the pleural cavity, so that the lung tissue can reopen and restore function. Otherwise, pus and some tissue fluid exist in the patient's body, and the patient needs to slowly eliminate and transform it, which will affect the healing of the postoperative wound. , as a treatment device, the drainage device is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of...

AI Technical Summary

Problems solved by technology

The previous drainage device is only a simple gravity drainage, which cannot control the drainage speed and degree, and is inconvenient to carry and adjust. It will also cause the backflow of the liquid in the drainage tube. If the drainage tube is not fixed well, it is easy to cause air to enter the chest cavity and affect the doctor's work efficiency; drainage The water-sealed bottle used is inconvenient to inject physiological saline in the case of first aid, and the valve is used as the filter medium, which is costly and inconvenient to replace
