Technical Field

The utility model relates to the technical field of medical equipment.

Background

The drainage tube is a medical appliance for drainage in clinical surgery, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. Surgical drainage is used for guiding pus, blood and liquid accumulated in human tissues or body cavities to the outside of a body so as to prevent postoperative infection and influence on wound healing. The drainage tube is generally a tube placed in a body cavity and is mainly used for draining blood, pus and other liquids after operation.

The clinical surgical drainage tubes are of various types, and the drainage tubes are placed in the thoracic cavity, the abdominal drainage tubes are placed in the abdominal cavity, and further comprise a stomach tube, a digestive juice draining gastrointestinal tract, a urinary tube and the like. In the case of a drainage tube, the condition of the drainage tube, including whether the drainage tube is unobstructed, the amount of drainage material from the drainage tube, and the nature of the drainage material from the drainage tube, is bloody, purulent, or otherwise observed each day.

At present, clinical drainage tubes are various in variety, and the size, the shape and the design of drainage tube joints are different, for example, nasobiliary tube drainage tube joints, PTCD tube drainage tube joints are all spiral joints, T tube drainage tube joints, wound drainage tube joints and the like are cylindrical joints such as 12Fr, 16Fr, 18Fr, 20Fr and 22Fr, and however, drainage bag and gastrointestinal pressure reducer joints which are common in clinic are all pagoda head joints. And the size of the joints with different specifications is different, so that the problem that the joint of the drainage tube is not matched with the joint of the drainage bag or the gastrointestinal pressure reducer frequently occurs when the drainage tube is used.

At present, medical workers mainly use a self-made tee joint, 2ml of injection, a sterilized rubber tube for connection or bridging of sterilized tourniquet materials, but the connection modes are all not firm, and the tourniquet is easy to fall off due to stress in the use process, so that adverse effects are caused to the health of patients.

In summary, how to design a multifunctional joint adapter capable of connecting various types of drainage tube joints with drainage bags and gastrointestinal pressure reducer joints is a technical problem which needs to be solved urgently at present.
