[0039] ​The utility model relates to a medical instrument for retaining enema operation treatment, in particular to an anal tube for enema operation. In order to understand the above-mentioned purpose, features and advantages of the utility model more clearly, the utility model will be described in further detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without mutual conflict.

[0040] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the scope described herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0041] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the anal tube of the utility model has an anal tube body 1 and a support guide wire 2.

[0042] Specifically, the forming structure of the anal tube body 1 adopts the existing latex flexible structure. The anal tube body 1 has an insertion front end (part inserted into the patient's body) and a drainage rear end (part retained outside the patient's body). The anal tube body 1 is a hollow tube structure with a head at the insertion front end. A plurality of oil storage sacs 4 are arranged on the outer wall of the head top end of the insertion front end of the anal tube body 1 in a capillary hole structure, and each oil storage sac 4 is filled with paraffin lubricating oil.

[0043] When performing enema operation on the patient, the insertion front end head of the anal tube body 1 is extruded with the perianal tissue of the patient, and the paraffin lubricating oil in the oil storage sac 4 is extruded and overflowed, lubricating the anal tube body 1 and the perianal tissue of the patient, facilitating the smooth and easy insertion of the anal tube body 1 into the patient's body, and reducing the damage and pain to the patient's skin.

[0044] Two front and rear staggered liquid filling holes 3 are also provided on the tube wall of the insertion front end of the anal tube body 1. During enema operation, the enema liquid is output from the liquid filling hole 3 through the hollow structure of the anal tube, and the patient is treated with enema.

[0045] An elastic sac 8 is arranged on the outer wall of the rear side of the liquid filling hole 3 of the insertion front end of the anal tube body 1, and the elastic sac 8 is composed of an elastic film connected to the outer wall of the anal tube body 1 in a sealed structure. A catheter 9 connected to the drainage rear end of the anal tube body 1 is connected to the elastic sac 8.

[0046] Further, the tube wall of the anal canal body 1 is provided with a U-shaped buried groove along the length direction, which is used as the buried conduit 9 and limits the conduit 9. The conduit 9 is embedded in the U-shaped buried groove on the tube wall of the anal canal body 1 along the length direction and extends outward from the drainage rear end of the anal canal body 1. The rear end of the extended conduit 9 is connected with a control valve for controlling the on / off state of the conduit 9. During the enema operation, according to the technical requirements of plugging or compression hemostasis, the medical staff opens the control valve, injects the inflation medium (such as normal saline / air) into the elastic bag 8 through the conduit 9, closes the control valve, and makes the elastic bag 8 keep radial expansion on the outer periphery of the anal canal body 1. At this time, the expanded elastic bag 8 can perform compression hemostasis on the bleeding site in the enema of the patient or plug the anus at the anus, and also can make the anal canal body 1 relatively fixed in the anus of the patient; when the enema treatment is finished, the medical staff opens the control valve, and the inflation medium in the elastic bag 8 is discharged through the conduit 9. At this time, the elastic bag 8 after pressure relief is elastically contracted and attached to the anal canal body 1, which is convenient for the extraction of the anal canal body 1.

[0047] Further, the drainage rear end of the anal canal body 1 is bifurcated into a tapered interface 5 and a luer lock interface 6, and the tapered interface 5 and the luer lock interface 6 respectively have corresponding plugs, which do not affect the switching use of the two. The tapered interface 5 and the luer lock interface 6 can be flexibly matched with commonly used syringes, drainage devices, drainage bags and the like in clinical use. It should be noted that when one of the joints is connected with the syringe, the drainage device, the drainage bag and the like, the other interface needs to be plugged with a plug.

[0048] In order to adjust the insertion hardness of the flexible structure of the anal canal body 1, the anal canal further has a support guide wire 2 for auxiliary support, the diameter of the support guide wire 2 is smaller than the inner diameter of the anal canal body 1, and one end of the support guide wire 2 has a guide wire operation head 7. In the enema operation, according to the adjustment requirement of the insertion hardness, the medical staff holds the guide wire operation head 7 and inserts the support guide wire 2 into the inner hole of the anal canal body 1 from the tapered interface 5, and the annulus between the outer wall of the support guide wire 2 and the inner wall of the anal canal body 1 does not affect the flow of the enema liquid. The front segment of the support guide wire 2 inserted in place abuts against the inner wall of the inner hole of the insertion front end of the anal canal body 1, at this time, the medical staff positions and connects the guide wire operation head 7 with the tapered interface 5 at the drainage rear end of the anal canal body 1, that is, the support guide wire 2 and the anal canal body 1 form an integral structure.

[0049] When the anal canal body 1 is inserted into the predetermined position of the patient in the enema operation, the medical staff detaches and separates the guide wire operation head 7 from the tapered interface 5, holds the guide wire operation head 7 and separates the support guide wire 2 from the inner hole of the anal canal body 1, at this time, the anal canal body 1 is inserted and positioned in the patient's body, and the subsequent enema operation can be performed.

[0050] While the preferred embodiments of the application have been described, those skilled in the art will note that various modifications and changes can be made thereto without departing from the spirit and scope of the application. Accordingly, it is intended that all such modifications and changes be included within the scope of the application as claimed.

[0051] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
