Abstract
Description
Technical Field
[0001] The utility model relates to a medical device, in particular to a drainage tube connector capable of inserting a sub-tube. Background Art
[0002] At present, although the anastomosis technology in gastrointestinal surgery has developed relatively maturely, anastomotic leakage still occurs from time to time. Anastomotic leakage is a serious complication of gastrointestinal resection and anastomosis surgery, which can lead to severe abdominal cavity infection in patients, malnutrition caused by fasting, and even septic shock, organ failure and death. For such patients, most of them adopt conservative treatment, that is, using a drainage tube to irrigate the abdominal cavity, strengthening anti-infection, nutritional support and other treatments. At present, during gastrointestinal surgery, the commonly used drainage tubes are rubber drainage tubes and silicone drainage tubes. Most of the drainage tubes do not come with a flushing sub-tube. Using such drainage tubes without a sub-tube, flushing cannot be carried out, and there is currently no drainage tube connector capable of inserting a sub-tube. It is necessary to insert a flushing drainage tube to carry out flushing and drainage. In view of this, the utility model deeply studies the above defects of the drainage tube without a sub-tube, and thus this case is generated. Content of the Utility Model
[0003] Aiming at the above problems, the purpose of the utility model is to provide a drainage tube connector capable of inserting a sub-tube, and the sub-tube of the drainage tube is inserted through the connector to solve the problems raised in the above background art.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a drainage tube connector capable of inserting a sub-tube, which is characterized in that: it includes a drainage tube connector cap, a drainage tube connector tube, a drainage bag interface, a sub-tube interface, a sealing threaded tube, and a nut; the drainage tube connector tube, the drainage bag interface, and the sub-tube interface are integrally formed structures. It is characterized in that: the sub-tube interface can insert the sub-tube of the drainage tube, and can insert pipelines such as an infusion set, a blood transfusion set, an extension tube, etc. for flushing.
[0005] The inner diameter of the drainage tube connector cap gradually decreases, which can seal and fix the drainage tube connector tube. When not in use, it can be connected to the drainage tube connector tube to avoid contamination and maintain sterility;
[0006] The drainage tube connector tube can be connected to the drainage tube, has threads on the surface, and the caliber decreases in a trapezoidal shape. The gradually decreasing diameter of the helix can keep the connection of the drainage tube stable;
[0007] The drainage bag interface of the connector is made of an elastic material, can be connected to the connector of the drainage bag, and the elastic material can keep the connection stable and at the same time seal to prevent the drainage fluid from overflowing;
[0008] The sub-tube interface of the connector has an elastic spiral ring and a sealing threaded tube on its tube wall. When not in use, this interface can be connected to a nut to close the sub-tube interface. When a sub-tube is inserted, the sealing threaded tube can be used to rotate and squeeze the elastic spiral ring to seal the sub-tube;
[0009] The sealed threaded tube is of a circular structure, with anti-slip threads on the surface and internal threads, and can be rotatably and fixedly connected to the elastic coil (5). After the sub-tube is inserted, by rotating the sealed threaded tube, the elastic material of the drainage tube of the sub-tube can be squeezed to seal the drainage tube of the inserted sub-tube and prevent the drainage fluid from overflowing.
[0010] The elastic coil has threads on the surface and is made of a highly elastic material. Rotating the sealed threaded tube can squeeze the highly elastic material to seal the sub-tube.
[0011] The nut is internally provided with a highly elastic rubber plug, which can block the interface of the sub-tube to prevent exposure to infection and the overflow of the drainage fluid.
[0012] Preferably, the angle between the drainage tube joint tube 2 of the drainage tube joint and the drainage bag interface 3 is an obtuse angle, and the angle between the drainage tube joint 2 and the sub-tube interface 6 is an obtuse angle; the angle between the drainage bag interface 3 and the sub-tube interface 6 is an acute angle.
[0013] Preferably, the drainage tube joint tube, the drainage bag interface, and the sub-tube interface of the drainage tube joint are in the same plane.
[0014] Preferably, the color of the drainage tube joint tube 2 is blue, and the drainage tube interface and the sub-tube interface are colorless and transparent.
[0015] The beneficial effects of the present utility model are as follows: When connecting the drainage tube, the drainage tube joint can insert the sub-tube of the drainage tube. The material of the sub-tube can be commonly used clinical materials such as an infusion set, a blood transfusion set, and an extension tube. It is convenient to use and has a stable structure. At the same time, by sealing the drainage tube with the sealed threaded tube, the overflow of the drainage fluid and air leakage can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The sub-tube interface 6 can be fixed and sealed with a nut 8. It closes the sub-tube interface through a highly elastic rubber plug 7 to achieve the purpose of sealing the interface, and has good sealing performance.
[0031] The sub-tube interface 6 of the drainage tube connector can be inserted into the sub-tube of the drainage tube. As Figure 3 shown, the material of the sub-tube can be commonly used clinical materials such as an infusion set 13, a blood transfusion set, and an extension tube. Cut off the needle head part of the infusion set, and insert the remaining pipeline through the sub-tube interface to act as the sub-tube. After insertion, the sub-tube can be sealed by selecting the sealing threaded tube 4 to squeeze the elastic coil 5; at the same time, this sub-tube interface can be applicable to sub-tube materials of different sizes, improving the convenience of use.
[0032] In this embodiment, the drainage tube connector tube 2 is made of plastic material, and the hard material can ensure the stable connection of the drainage tube;
[0033] In this embodiment, the drainage bag interface is made of elastic material, and the elasticity can ensure the sealing performance.

The treatment among the three included angles can be a straight-arm angulation, but is not limited to straight-arm angulation, and an arc treatment can be adopted.
[0035] In this embodiment, the elastic coil 5 is made of elastic material, has threads on the surface, and matches the inner thread 9 of the sealing threaded tube 4. The diameter of this elastic material gradually increases, and different-sized sub-tubes can be sealed after rotation.
[0036] In this embodiment, the drainage tube connector tube 2, the drainage bag interface 3, and the sub-tube interface 6 are on one plane, but are not limited to a plane.
[0037] In this embodiment, the color of the drainage tube connector tube 2 is blue, and the colors of the drainage bag interface 3 and the sub-tube interface 6 are colorless and transparent, but are not limited to any color.
