A drainage tube connector

technical field

The utility model relates to a component of a medical appliance, in particular to a drainage tube connector.

Background technique

Drainage tube is a common clinically used surgical catheter. Its main function is to guide pus, blood or fluid accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing.

In the existing clinical medical treatment process, one end of the drainage tube is connected to the human body, and the other end needs to be connected to an external drainage bag. As shown in Figure 1, it is a schematic diagram of the connection between the drainage tube and the drainage bag in the prior art. The left half of the figure is the end of the drainage tube, and its structure is a simple open tube; the right half is the extension of the drainage bag. The leading tube that comes out has a tapered head with a small front and a big rear. In actual use, the two ends need to be connected to lead the liquid to the inside of the drainage bag. And because the drainage tube and the drainage bag are two different items, their sizes, specifications, and manufacturers are different, so when they are connected together, many mismatches will occur, resulting in the need for medical personnel to do so in the actual operation process. It can only be connected violently, which has caused a lot of unnecessary troubles. Simultaneously, the connection mode of the drainage tube in the prior art cannot realize the effect of flushing the tube, which is very inconvenient. Flushing is to flush the pipeline with normal saline before certain special medication.

Therefore, there is an urgent need for an easy-to-use drainage tube connector to solve the above problems.

By adopting the above-mentioned technical solution, the positional relationship between the drainage tube and the drainage bag can be connected through the connection head, and the connection head is set to be hollow, and an opening is provided at the end, and the diameter of the opening is further adjusted. It can be well matched with the tube on the drainage bag for insertion. Compared with the connection mode between the drainage tube and the drainage bag in the prior art, it is more convenient in the specific operation process, and can solve the problems such as size mismatch between the drainage tube and the drainage bag.

Preferably, a fastening device is also connected between the extension section and the connector.

Preferably, the fastening device includes a fixed sleeve sheathed at the joint between the extension section and the connector, the end of the fixed sleeve opposite to the connector is provided with an internal thread, and the outer surface of the connector is provided with an outer thread that cooperates with it. thread; the position of the extension section opposite to the fixed sleeve is provided with a limit ring, and the inner diameter of the connection part between the fixed sleeve and the extension section is smaller than the diameter of the limit ring. Through the above technical solution, the connection head and the extension section can be further fixedly connected through the fixing sleeve, one end of the fixing sleeve is fastened to the connection head through the thread, and the other end is through the limit ring arranged on the extension section, which can It is limited in the axial direction, so that the fit between the connecting head, the extension section and the connecting end is tighter.

Preferably, a first sealing cap is provided at the opening of one end of the connecting head connected to the drainage bag. The first sealing cap functions as a cover, which can well seal the drainage tube.

Preferably, a flushing hole is provided on the surface of the first sealing cap, and a second sealing cap for sealing the flushing hole is arranged on the flushing hole. The setting of the flushing hole can facilitate the operation of the medical staff to flush the tube before special medication, and at the same time, the second sealing cap can well seal the flushing hole so that it can be opened for flushing when needed. Time to close and seal.

Preferably, the first sealing cap is fixedly connected to the connection head.

Preferably, the second sealing cap is fixedly connected to the first sealing cap. Such an arrangement allows the first sealing cap, the second sealing cap and the connecting head to be fixed as a whole, so that the sealing cap will not be discarded and lost when the sealing cap is opened.

Compared with the prior art, the utility model has the advantages that it is more convenient for medical personnel to connect the drainage tube and the drainage bag, and at the same time, it can perform the flushing operation in the tube before medication according to different situations.

Detailed ways

Referring to Fig. 1 to Fig. 2, an embodiment of a drainage tube connector of the present invention will be further described.

As shown in Figure 2, it is a schematic diagram of an embodiment of the drainage tube connector of the present invention, where the extension section 2 provided at the end of the drainage tube is connected with a connector 3, and this connector 3 is connected to the extension section 2 at the end of the drainage tube. It is detachably connected. In this embodiment, for more convenience in actual use, the connecting head 3 is sheathed on the outside of the end of the extension section 2 . Further, the connector 3 is set as a hollow tube, one end has a larger inner diameter and the other end has a smaller inner diameter, the smaller end of the connector 3 is connected to the extension section 2, and the larger end is connected to the drainage bag.
