Description

Safe double-cavity closed thoracic drainage tube capable of performing thoracic injection

Technical Field

The utility model relates to a medical treatment drainage technical field, more specifically say, the utility model relates to a safe type two-chamber thorax closed drainage tube that can carry out thorax injection.

Background

Closed thoracic drainage is to put one end of the drainage into the thoracic cavity and put the other end into a water-sealed bottle lower than the drainage end so as to discharge gas or collect liquid in the thoracic cavity and rebuild negative pressure of the pleural cavity. Besides the drainage function, the thoracic cavity injection can be carried out through a closed thoracic cavity drainage tube. Some therapeutic drugs are directly injected into the chest cavity to play a role in local treatment. However, the currently clinically used closed thoracic drainage tubes are straight tubes, and when thoracic injection treatment or diagnosis is needed, a syringe needle needs to be used to pierce the closed thoracic drainage tube for thoracic injection, so that the risk of occupational exposure caused by needle stick injury exists. And silica gel drainage tube texture is harder, adopts 7 and above needles to go on mostly clinically, pulls out the needle back, leaves the puncture hole, though clinical adoption pastes the film and carries out the puncture hole cover, still has the risk of being connected with the external world in the chest pipe, and then arouses complication such as pneumothorax, infection.

In order to reduce the pain of the patient after the closed thoracic drainage operation and increase the comfort, the diameter of the closed thoracic drainage tube is gradually reduced. The specifications and types of the closed thoracic drainage tubes which are commonly used clinically at present are Fr16-Fr 32. However, most of the connectors of the existing thoracic closed drainage bottles are standard fittings, which causes the current situation that the diameter of the thoracic closed drainage tube is reduced and the connector is not changed. When connecting thorax closed drainage bottle, medical personnel need spend more strength and remove fixed connection, and because not supporting, only the coupling part phenomenon can appear, easily arouses the unexpected separation of junction, causes complications such as pneumothorax, and then influences the quick recovery of patient, extension time in hospital.

The closed thoracic drainage tube which is commonly used clinically at present is calibrated by zero from the head end, and is usually marked to 25cm, so that the lower segment part has no scale. And the clinician can cut out the length of entering the pipeline according to the actual need of the patient sometimes, when the exposed part has no scale display, the built-in length can not be recorded, and the exposed length needs the nurse to take the ruler to measure, thus increasing the workload.

It is therefore desirable to provide a safe dual-lumen closed thoracic drain that allows for thoracic injection.
