Description

Disposable emulsion anal fistula drainage device

Technical Field

The utility model relates to a simple drainage device specially used for anal fistula drainage and made of medical emulsion, belonging to the technical field of medical appliances.

Background

Anal fistula is a surgical common benign anal disease, forming an infectious fistula of the skin-rectum, often occurring after perianal abscess, and is prone to recurrent attacks and prolonged disunion. The anal fistula hanging wire drainage is a common mode of anal fistula treatment, can be used for drainage of a pus cavity before anal fistula treatment and can be used for forming a regular fistula, the anal fistula hanging wire can also be used for treatment, and the anal sphincter necrosis is caused by tightening the hanging wire for treatment.

The thread for anal fistula is generally cotton thread, and the thread for surgical suture is used in practical work, or can be soaked on cotton thread or thread as a method for treatment. The method has the advantages that although the method is easy to obtain, the method is inconvenient, particularly for patients, the strands of silk threads are often wet, and the silk threads and silk threads are sticky with excrement, so that the skin feel uncomfortable, the inflammation is easy to cause, and the anal fistula drainage is difficult to clean.

Disclosure of Invention

Aiming at the problems, the utility model provides a simple drainage device specially used for anal fistula drainage, which is made of medical emulsion and is used for being placed into a patient in an outpatient clinic without suffering. So as to solve the discomfort of the thread hanging drainage, avoid the excrement from entering the fistula, and carry out the operations such as flushing, etc.

In order to achieve the technical purpose, the utility model adopts the following scheme:

a disposable emulsion anal fistula drainage device comprises an anorectal part of the drainage device, a skin part of the drainage device and a plastic strip part. One end of the anorectum part of the drainage device is provided with a round cap which is connected with a hollow straight pipe, the outer wall of the straight pipe is provided with a side hole, and the outer side wall of the straight pipe is provided with a raised tenon structure. One end of the skin part of the drainage device is provided with a round cap which can be used for connecting the syringe, the round cap is connected with a hollow straight pipe, and mortise holes are formed in the wall of the straight pipe. The anorectum part of the drainage device can be placed in the plastic strip part in an auxiliary mode and is clamped and fixed with the skin part of the drainage device through the mortise and tenon structure.

Further, the diameter of the circular cap of the anorectal part of the drainage device is 1.0-3.0cm, the outer diameter of the straight pipe is 0.3-0.7cm, and the inner diameter of the straight pipe is 0.1-0.2cm. The side holes arranged on the outer wall of the straight pipe are 3-6 groups.

Further, the diameter of the circular cap of the skin part of the drainage device is 1.0-2.0cm.

Further, the diameter of the plastic strip part round bar structure is 0.3cm, one end of the plastic strip part round bar structure is a blunt end, and a small concave is arranged at the blunt end.

Further, the anorectal part of the drainage device and the skin part of the drainage device are made of medical emulsion, and the plastic strip is made of plastic.

The utility model provides a simple drainage device specially used for anal fistula drainage, which is made of medical emulsion and has the following advantages: (1) easy placement, no need of anesthesia, and easy implementation, and can be completed during clinic consultation; (2) the drainage can be smooth, and the patient can wash the device when taking a bath, so that the discomfort of the patient with a plurality of wet threads for drainage is obviously reduced; (3) the latex tube may assist in the formation of a relatively straight drainage sinus wall and a thin tube at its inner orifice may be used for irrigation. The flushing water/drug outlet leaves 3-6 fine holes at the straight tube of the rectum side of the fistula drainage; (4) when the patient defecates, the inner circular cap of the drainage device can cover the inner opening of the rectum side of the fistula due to the increase of the pressure in the rectum, so that the excrement does not enter the fistula.

Detailed Description

Embodiments of the present utility model will be described in detail below with reference to fig. 1-3. It should be noted that the present utility model is briefly and clearly illustrated by a disposable latex anal fistula drainage device as illustrated in the accompanying drawings, which should not be construed as limiting the scope of the utility model.

As shown in fig. 1, the anorectal portion 1 of the drainage device has a circular cap 11 at one end, which can be used for fixation, and the circular cap 11 is connected with a hollow straight pipe 12. The outer wall of the straight pipe is provided with a side hole 13, and the outer side of the straight pipe is provided with a raised tenon 14 for being clamped with the skin part of the drainage device.

As shown in fig. 2, the skin portion 2 of the drainage device has a circular cap 21 at one end for fixing, the circular cap 21 has an opening 22 connected with a hollow straight tube 23, and the opening 22 can be used for connecting a syringe. The wall of the straight pipeline 23 is provided with mortise holes 24.

As shown in fig. 3, the plastic strip 3 has a blunt end 31 at one end, and a dimple 32 is provided at the blunt end 31. Here, the blunt tip 31 and the dimple 32 have two roles: (1) the small concave 32 is used for binding the silk threads and preventing the silk threads from falling off; (2) the force at the blunt tip 31 is not too great or does not readily form a passageway when inserting the plastic strip.

When in use, the plastic strip part is inserted from the anal fistula external orifice of the skin, the plastic strip is led out from the anus rectum along the fistula, and is tied by the medical silk thread after being pulled out of the anus, and is tied with the straight pipe of the anus rectum part of the drainage device. Further, the anorectum part of the drainage device is pulled into the fistula from the outside of the anus and pulled out of the skin, the tightness of the anorectum part of the drainage device is adjusted to be not loose and not tight, and the circular cap of the anorectum part of the drainage device is attached to the inner opening of the rectal wall. Then, the redundant straight pipelines of the anorectum part are sheared off and sleeved into the straight pipelines of the skin part of the drainage device, so that the protruding tenon structures of the anorectum part of the drainage device are clamped with mortise holes of the skin part of the drainage device, and at least three groups of tenons and mortise holes are clamped. Wherein, the interval between the tenon is unanimous with the interval between the mortise in order to the block. The length of the cutting tube is enabled to be clung to the external opening of the anal fistula, thus the purpose of placing the anal fistula drainage in the clinic is achieved.

In summary, while embodiments of the present utility model have been described, it will be understood that the above embodiments are illustrative, and not limiting, and that variations, modifications, substitutions and alterations of the above embodiments may be made by those skilled in the art without departing from the spirit and principles of the present utility model, and such variations, modifications, substitutions and alterations are also to be seen as being within the scope of the present utility model.
