[0001]

[Industrial applications]

 The present invention relates to a disposable hemorrhoids treatment tool for hemorrhoids cold therapy, and more particularly, to a highly safe and disposable hemorrhoids treatment tool that is mainly effective for the treatment of internal hemorrhoids and does not have a risk of immersing in the rectum.

[0002]

[Prior Art]

  Background of the Invention Hemorrhoids, or hemorrhoids, is a varicose vein disease that occurs near the anus and is roughly divided into internal hemorrhoids and external hemorrhoids with the anus ring as the boundary. Along with this, bleeding from internal hemorrhoids is particularly remarkable.

[0003] Conventionally, surgery has been recommended for the radical treatment of hemorrhoids, but due to postoperative pain and concerns about sequelae such as deformity of the anus, many patients cannot complete the surgery and the effect is not satisfactory. There are quite a lot of cases where reliance on topical medication such as suppositories is still sufficient. Therefore, relatively recently, a rod-shaped body containing a cooling medium liquid called cryotherapy was frozen in a freezer and then inserted into the anus for a short time to stimulate veins in the affected area. Therapies for relieving varicose veins are being performed with active blood flow, and a leaking head 23 is already formed at the rear of the synthetic resin rod 22 containing the cooling medium liquid C as shown in FIG. Product 21 marked with is on the market.

Problems of the Prior Art However, since the above-mentioned known product 21 is not disposable, it is not possible to remove the resistance to re-cool it in a freezer containing food after use. In addition, since the picking part (head 23) is small, not only the fingertip may touch the anus during the insertion operation, but it may be accidentally immersed in the rectal cavity due to the force of insertion, and it may be removed medically. There are even cases that required treatment.

[0005]

[Problems to be solved by the device]

 In view of the above circumstances, the present invention is not unclean and has a sufficient length for insertion and grasping, so it is easy and clean to handle, the insertion state is stable, and there is no risk of over-insertion at a low cost. An object is to provide a disposable hemorrhoidal treatment device for cooling therapy.

[0006]

[Means for Solving the Problems]

  Concept The inventors of the present invention have obtained the following recognition as a result of various examinations from the clinical point of view on the characteristics that should be possessed by the hemorrhoid treatment device for cooling therapy.

(A) In order to prevent slipping out due to the strain that inevitably occurs at the time of insertion, it is preferable that the whole is a rod-shaped body that is not so thick, but on the other hand, since the content cooling medium liquid amount decreases, To make up for it, the total length should be quite long. Moreover, the extension of this major axis should facilitate gripping during insertion.

(B) If a brim is provided in the middle of the rod-shaped body, over-insertion can be completely prevented, and finger contact with the anus can be effectively prevented.

(C) On the other hand, in order to obtain a low-cost, disposable product, there is nothing but hollow molding of general-purpose thermoplastic plastics, but then it becomes difficult to mold the tsuba. That is, it is difficult to form a thin flange due to the female structure, and if the flange is hollowed out with a large diameter, the wall thickness of the edge becomes too thin and there is a risk of rupture due to freezing of the cooling medium liquid inside. To be. Furthermore, even if it does not rupture, the low-temperature cooling medium liquid in the collar may adversely affect lesions such as fissures. Therefore, it is possible to apply it to the treatment of external hemorrhoids by making the collar part separate and filling the inside with cooling medium liquid as needed.

[0010] Based on the above findings, the present invention can be stably inserted into the rectal cavity as a whole, and at the same time has a sufficient length for grasping with a fingertip, and the inside is filled with a cooling medium liquid. A gist of the present invention is a disposable hemorrhoid treatment tool comprising a hollow rod-shaped body made of synthetic resin and a detachable collar that can be locked at an intermediate portion of the rod-shaped body. In the following, the various elements that make up the device will be described separately by item.

Hollow Rod-Shaped Body The hollow rod-shaped body in the present invention is, for example, a straight rod-shaped body having an outer diameter of about 10 ^m / _m . The whole is preferably integrally manufactured from a harmless general-purpose soft synthetic resin having a low embrittlement temperature such as polypropylene, polyethylene, and polyurethane by a hollow molding means. The length from the collar attachment position to the tip of the rod-shaped body is usually an appropriate length (for example, 70 to 80 mm) to reach the inside of the rectum beyond the anal ring. This is in order to prevent contact with the internal hemorrhoid sufficiently and at the same time to prevent it from coming out due to the unavoidable stress that occurs during insertion. The thickness is set to an outer diameter that allows it to pass through the anal ring comfortably (for example, around 10 ^m / _m ), but if possible, a larger diameter will improve the cooling capacity.

The rod-shaped body should be provided with an engaging means such as an engaging ridge or a step for engaging the collar at the intermediate collar mounting position. It is preferable to provide a plurality of these engaging means, if necessary, so that the installation position of the collar can be adjusted.

The tsuba functions as a stopper for preventing over-insertion, and for this purpose, it is usually configured as a disk body having a diameter of 20 ^m / _m or more, preferably 30 ^m / _m or more. In addition, in order to soften the irritation to the anus as much as possible, this product is made of rubber or soft synthetic resin, and is made into a hard sponge-like shape that functions as a stopper or is shaped into a hollow shape. Is preferred. The shape of the hollow disk body is a torus, that is, a so-called donut shape or a shape close thereto. If necessary, the hollow portion can be filled with a cooling medium liquid for cooling external hemorrhoids.

Gripping Part Since the rear part of the rod-shaped body from the brim installation position serves as a gripping part at the time of insertion, the length is not particularly limited. However, specifically, it is preferable that the length is 20 mm or more. A flat fusion-bonding portion is provided at the rear end of the main grip portion, but it is convenient to remove the post-treatment by making a hole in this fusion-bonding portion and passing a string through this hole.

Cooling medium liquid The inside of the rod-shaped body needs to be filled with a cooling medium liquid. This is because the liquid of the cooling medium does not reach the inside of the expanded portion when it is horizontally placed in the freezer and hinders the cooling effect unless it is fully filled or close to it. However, it does not have to be completely full in a complete sense, and if a freezing liquid is used as the cooling medium liquid, it is rather prevented from abnormal expansion or rupture due to freezing. It is preferable to be in a state close to fullness with room for expansion.

Examples of the cooling medium liquid include water, ethanol, isopropanol, glycerin, ethylene glycol, propylene glycol, butylene glycol and other monohydric or polyhydric alcohols or aqueous solutions thereof, urea aqueous solutions, sodium chloride or chloride. An electrolyte solution such as potassium, magnesium chloride or sodium sulfate, an aqueous solution of a polysaccharide such as carboxymethyl cellulose, or the like is used, but it is not limited thereto. However, since ice is the most commonly used material with the highest latent heat of melting, it is rational to select a composition that freezes water mainly at freezer temperatures (around -20 ° C). As a typical composition, for example, propylene glycol, sodium polyacrylate, potassium chloride or sodium chloride alone or in an aqueous mixed solution is exemplified.

Manufacture Normally, after the cooling medium liquid is injected from the rear part of the rod body with the engaging means manufactured by using the blow molding means, the ends are heat-sealed. The formation of partition lines associated with ordinary blow molding should be avoided as much as possible, and especially, the residual cutting line at the tip of the rod-shaped body is not preferable. Therefore, it is preferable to form by injection blow method. Is desirable. The product obtained is preferably gas-sterilized and then sealed in a sterile outer packaging.

[0018]

[Action]

 Since the hemorrhoid treatment device according to the present invention has the brim in the middle of the rod-shaped main body, over-insertion is completely prevented, and a grip portion having a sufficient length behind the brim is formed. Therefore, the insertion operation is easy, and there is no risk of the finger touching the anus. Moreover, since the collar part is separate from the main body, it is not subject to various restrictions due to the molding method, and a flexible and free material, shape and structure can be adopted for the anus part, and the installation position can be changed appropriately. Occurs.

Furthermore, since the whole is disposable, not only the unclean feeling of re-cooling in the freezer is wiped out, but also clean instruments can always be used hygienically.
