Description

Technical Field

[0001] This utility model relates to medical devices, and in particular to a disposable anal tube. Background Technology

[0002] Rectal administration refers to the delivery of medication into the intestines through the anus, where it is rapidly absorbed through the rectal mucosa and enters the systemic circulation to exert its therapeutic effect on systemic or local diseases. There are three main methods of rectal administration: retention enema, rectal drip, and suppository insertion. Disposable rectal tubes are often required during rectal administration.

[0003] The rear end of the anal tube needs to connect with the sewage pipe. Since there is no constraint at the rear end of the anal tube, it will slowly enter the sewage pipe under the pushing force of the front end, causing the front end of the anal tube to detach. Therefore, the connection structure between the anal tube and the sewage pipe needs to be designed to prevent the detachment phenomenon. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a disposable anal tube to solve the problem of the anal tube coming loose after being connected to the sewage pipe.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a disposable anal tube, comprising a front tube, a middle tube, a rear tube connected to a sewage pipe, and a medicine tube connected to the middle tube. The outer wall of the connection between the rear tube and the middle tube is provided with a bowl-shaped plug, the diameter of which is larger than the diameter of the rear tube. An arc-shaped groove is formed on the side of the plug facing the sewage pipe. Several sealing rings are provided on the surface of the rear tube. The principle of this utility model is as follows: the anal tube is inserted into the patient's anus from the front end and connected to the sewage pipe from the rear end. Medication is injected through the medicine tube. During connection, the rear tube is inserted into the sewage pipe. The sealing rings on the outer wall of the rear tube enhance the reliability of the connection between the rear tube and the sewage pipe, preventing sewage from leaking out through the gap between them. The end of the sewage pipe is located within and abuts against the arc-shaped groove of the plug, preventing the anal tube from further entering the sewage pipe and thus preventing the front end of the anal tube from dislodging.

[0006] As an improvement, the front section pipe, middle section pipe, rear section pipe, plug and sealing ring are integrally injection molded.

[0007] As an improvement, the outer wall of the front tube is provided with several drug delivery holes.

[0008] As an improvement, a water-stop clamp is provided on the middle section of the pipe.

[0009] As an improvement, the length of the front section of the tube is 17-18cm, the length of the middle section of the tube is 30-35cm, and the length of the rear section of the tube is 8-12cm.

[0010] The beneficial effects of this utility model compared with the prior art are:

[0011] The anal tube is inserted into the patient's anus from the front end and connected to the sewage pipe from the rear end. Medication is injected through the medication tube. During connection, the rear section of the tube is inserted into the sewage pipe. The sealing ring on the outer wall of the rear section of the tube can enhance the reliability of the connection between the rear section of the tube and the sewage pipe, and prevent sewage from leaking out from the gap between the rear section of the tube and the sewage pipe. The end of the sewage pipe is located in the arc-shaped groove of the plug and abuts against it. The plug can prevent the anal tube from entering the sewage pipe further, thereby preventing the front end of the anal tube from dislodging. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the present invention.

[0013] Figure 2 This is a cross-sectional view of the junction between the anal tube and the sewage pipe. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 , 2 As shown, a disposable anal tube includes a front tube 1, a middle tube 2, a rear tube 3 connected to a drain pipe 9, and a medication tube 6 connected to the middle tube 2. The front tube 1 is 17-18 cm long, the middle tube 2 is 30-35 cm long, and the rear tube 3 is 8-12 cm long. The outer wall of the front tube 1 has several medication holes. The medication tube 6 delivers the medication into the anal tube, which then enters the body through the medication holes at the front end of the anal tube. The middle tube 2 is equipped with a water-stop clamp 7. After the medication is injected into the body, the water-stop clamp 7 clamps the middle tube 2 to prevent the medication from leaking from the rear end of the anal tube into the drain pipe 9, thus keeping the medication absorbed within the body for a period of time. The outer wall of the connection between the rear section pipe 3 and the middle section pipe 2 is provided with a bowl-shaped plug 4. The diameter of the plug 4 is larger than the diameter of the rear section pipe 3. The plug 4 forms an arc-shaped groove on the side facing the sewage pipe 9. After the anal pipe is connected to the sewage pipe 9, the plug 4 abuts against the sewage pipe 9. The surface of the rear section pipe 3 is provided with several sealing rings 5. The sealing rings 5 ​​are integrally formed with the rear section pipe 3. The sealing rings 5 ​​are flexible and can be deformed and inserted into the sewage pipe 9. The front section pipe 1, the middle section pipe 2, the rear section pipe 3, the plug 4, and the sealing rings 5 ​​are integrally injection molded.

[0016] The principle of this invention is as follows: The anal tube is inserted into the patient's anus from the front end and connected to the sewage pipe 9 from the rear end. Medication is injected from the medicine tube 6. During connection, the rear section of the tube 3 is inserted into the sewage pipe 9. The sealing ring 5 on the outer wall of the rear section of the tube 3 can enhance the reliability of the connection between the rear section of the tube 3 and the sewage pipe 9, and prevent sewage from leaking out from the gap between the rear section of the tube 3 and the sewage pipe 9. The end of the sewage pipe 9 is located in the arc-shaped groove of the plug 4 and abuts against it. The plug 4 can prevent the anal tube from entering the sewage pipe 9 further, thereby preventing the front end of the anal tube from dislodging.
