Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a connector for a T-shaped drainage tube. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage, directing pus, blood, and fluids accumulated between tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. One end of the drainage tube is inserted into the patient's body, while the other end is connected to a drainage bag, where the accumulated fluid is directed. Drainage tubes come in a variety of shapes and sizes for different conditions. T-shaped drainage tubes, in particular, are thinner and do not match the diameter of the drainage bag connector, making them difficult to securely connect directly to. A connector is needed to quickly and stably connect the T-shaped drainage tube to the drainage bag.

[0003] The Chinese patent document with authorization publication number CN214679555U discloses a connection structure for a T-tube and a drainage bag specifically for hepatobiliary and pancreatic surgery, comprising a T-tube and a drainage bag, wherein the drainage bag is connected to the drainage tube, the end of the T-tube being fixedly connected to a first connector tube, the inner wall of the first connector tube being provided with an internal thread, the end of the drainage tube being connected to a second connector tube, the outer surface of the second connector tube being provided with an external thread that mates with the internal thread of the first connector tube. The T-tube and the drainage tube of the utility model are connected via threads between the first connector tube and the second connector tube, which is convenient and quick and not easy to fall off. Moreover, when the drainage bag is not in use, the first connector tube can be plugged with a plug, avoiding the risk of bile leakage caused by the poor sealing of existing materials and the risk of infection caused by bacterial infiltration due to local loose plugging of the connector. The utility model involves the redesign and improvement of the T-tube and drainage bag, which is too expensive, and the improved T-tube and drainage bag cannot be used in other occasions, which easily leads to waste and loss of resources, resulting in poor practicality of the utility model.

DETAILED DESCRIPTION

[0020] The present invention is further described below through specific embodiments, but the scope of the present invention is not limited thereto.

[0021] Example 1

[0022] A T-shaped drainage tube connector, the structure of which is as follows Figure 1-Figure 3 As shown, it includes a connected drainage section and a connecting section. The drainage section includes a fixed tube 1 that mates with the connector 14 of the drainage bag 13. The connecting section includes a plug-in tube 7 that mates with the T-shaped drainage tube 12. The plug-in tube 7 is fixedly connected to the connecting tube 2, which is fixedly connected to the fixed tube 1. The diameters of both the fixed tube 1 and the plug-in tube 7 are smaller than the diameter of the connecting tube 2. A plug-in handle 3 is fixedly connected to the end of the connecting tube 2 near the plug-in tube 7. The plug-in handle 3 is a circular ring structure coaxial with the connecting tube 2. The fixed tube 1 is an elastic tube; the connecting tube 2 and the plug-in tube 7 are both rigid tubes; the plug-in handle 3 is a rigid handle.

[0023] The plug-in tube 7 is provided with connecting threads 8 that mate with the T-shaped drainage tube 12. The plug-in tube 7 is hollow and conical in shape, and is fitted with an elastic ring 6 that fits within it. A traction connection ring 4 is provided on the side of the plug-in handle 3 near the plug-in tube 7. This traction connection ring 4 is connected to the elastic ring 6 via a traction connection line 5. The plug-in tube 7 has a thicker end near the connecting tube 2 and a thinner end away from the connecting tube 2. A scale 10 and an exhaust pipe 9 are provided on the connecting tube 2. A pipe clamp 11 is provided on the fixed tube 1.

[0024] The drainage section is fixedly connected to the joint 14 of the drainage bag 13 through the fixed tube 1, and the connecting section inserts the insertion tube 7 into the interface of the T-shaped drainage tube 12 through the insertion handle 3 on the connecting tube 2. The connecting thread 8 can increase the friction between the insertion tube 7 and the T-shaped drainage tube 12, thereby reducing the probability of the insertion tube 7 and the T-shaped drainage tube 12 being detached; then, the position of the elastic ring 6 is adjusted so that the elastic ring 6 is tightly stretched on the interface of the T-shaped drainage tube 12, further improving the connection stability between the T-shaped drainage tube 12 and the insertion tube 7, and the traction connecting ring 4 limits the elastic ring 6 by traction connecting line 5 to prevent the elastic ring 6 from detaching from the insertion tube 7.

[0025] When measuring the drainage volume of a patient within a certain period of time, close the tube clamp 11 on the fixed tube 1, so that the drainage fluid is gathered in the connecting tube 2, and the gas is discharged from the connecting tube 2 along the exhaust pipe 9. After the set time is reached, the drainage volume is read through the scale 10 on the connecting tube 2, which is convenient for doctors to evaluate and diagnose the patient's condition.

[0026] Example 2

[0027] A connector for a T-shaped drainage tube, which differs from Example 1 in that: the annular structure includes a pressing ring sleeved on the connecting tube 2, and pressing handles are symmetrically arranged on the pressing ring.

[0028] The above description is only a preferred embodiment of the present invention, but is not limited to the above examples. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
