The present invention further relates to a safe hemorrhoid treatment tool for cold therapy, which can be easily taken out by forceps even if it is additionally immersed 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.

Surgery has been conventionally recommended for the curative treatment of hemorrhoids, but many patients are unable to operate due to post-operative pain, deformity of the anus, etc. There are very many cases that rely on local medication such as. Therefore, relatively recently, a rod-shaped body containing a cooling medium solution called cryotherapy was frozen in a freezer, and then inserted into the anus for a short time to stimulate the veins of the affected area, thereby reducing blood flow. A therapy for relieving varicose veins is being performed with a vigorous flow, and as shown in FIG. 10, a leaking head 3 ′ is already provided at the rear of the synthetic resin rod 2 containing the cooling medium solution 4. Product 1'with a mark is commercially available.

However, in the known product 1 ′ described above, since the cooling medium liquid 4 exists only inside the rod-shaped body 2, it cannot be applied to the cooling therapy for external hemorrhoids, and at the time of insertion operation. In some cases, not only the fingertips may touch the anus, but they accidentally immerse themselves in the rectum and require medical treatment for removal. In addition, since it is not disposable, it is not possible to dispel the feeling of recooling it in a freezer containing food after using it.

[0005]

[Problems to be solved by the device]

 In view of the above circumstances, the present invention is not only applicable to cooling therapy for external hemorrhoids, but there is no risk of the fingertips touching the anus during insertion, and a disposable disposable hemorrhoids therapy tool for cooling therapy is provided. The purpose is to provide.

[0006]

[Means for Solving the Problems]

  In order to solve the above problems, the present invention is a hollow rod-shaped body made of a synthetic resin, the interior of which is filled with a cooling medium liquid, wherein the rod-shaped body is provided with a disc-shaped enlarged portion in the middle thereof. In addition, the rear end of the enlarged portion forms a holding portion for gripping with a finger pad, and the length from the enlarged portion to the tip portion is appropriate for insertion into the rectum. The main feature is a disposable hemorrhoids treatment tool. Hereinafter, various elements constituting the device will be described in terms of each item.

Hollow Rod-Shaped Body The hollow rod-shaped body according to the present invention is characterized in that it is provided with a disc-shaped enlarged portion in an intermediate portion. The whole is preferably integrally manufactured by a hollow molding means from a harmless general-purpose soft synthetic resin having a low embrittlement temperature such as polypropylene, polyethylene, or polyethylene terephthalate. The length from the plate-like enlarged portion to the tip portion is usually a length (eg, 70 to 80 mm) suitable for exceeding the anal ring and reaching the inside of the rectum. This is to prevent contact with the internal hemorrhoids and to prevent them from coming out due to 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.

It is suitable for contacting the external hemorrhoid nucleus portion that the above-mentioned plate-shaped enlarged portion has an outer diameter of about 20 to 40 ^m / _m experimentally, but of course, it is not limited to this size. . Further, the thickness thereof does not have to be constant, but rather a so-called leaking or frustoconical outer shape whose diameter gradually increases or decreases from the central portion to the peripheral portion, as shown in Embodiment 2 or 3 below. Is more suitable for contact with the external hemorrhoid. In particular, the one provided with the enlarged portion of the flanged bulb type which is a modification of the truncated cone shape shown in the third embodiment has a great cooling effect on the external hemorrhoidal nucleus and at the same time can prevent erroneous insertion.

There is no particular limitation on the length of the grip portion located behind the board-shaped enlarged portion. However, from a practical point of view, it is desirable that the length be at least as long as it can be grasped by the fingertip for insertion. Specifically, it is preferable that the length is 20 mm or more. Is formed (Example 3) or the rearmost part thereof is enlarged in a disk shape (Example 4), the insertion operation is further facilitated.

[0010] In still another aspect, the gripping portion can be provided with an engaging means such as a projection (fifth embodiment) for engaging forceps, a step portion (sixth embodiment), or a ring, whereby erroneous insertion is performed. It is easy to remove the time.

Cooling medium liquid The inside of the rod-shaped body needs to be filled with a cooling medium liquid. This is because the cooling medium liquid does not reach the inside of the expansion part when it is laid horizontally horizontally in the freezer unless it is full or close to it, which impedes the cooling effect. 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 body with a disk-shaped enlarged part manufactured by using 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. As shown in Example 6 described later, a cap with a screw may be used for heat welding.

[0014]

[Action]

 The hemorrhoid treatment device according to the present invention is provided with a disk-shaped enlarged portion in the middle portion thereof and is filled with the cooling medium liquid, so that the cooling medium liquid can be placed in the enlarged portion even if it is placed in a freezer in any posture. Is frozen in a state of being filled. Therefore, when this is inserted into the anus, the enlarged portion comes into contact with the external hemorrhoidal nucleus portion, so that a sufficient cooling effect can be obtained also on the enlarged hemorrhoidal portion, and thereby the healing effect is comprehensively increased. Moreover, since the grip portion is provided behind the disc-shaped enlarged portion, it is possible to avoid contact of the finger with the anus portion during insertion. Further, since the whole is disposable, not only the unclean feeling of recooling in the freezer is wiped out, but also the always sterilized instrument can be used hygienically.

It should be noted that, as one of the preferred embodiments, if the holding portion is provided with a projection or a step portion or a ring for engaging forceps, the safety when it is erroneously inserted into the rectum is guaranteed.

EXAMPLES Hereinafter, embodiments of the invention will be described with reference to examples, but the exemplification is merely for the purpose of explanation, and does not mean a limitation or limitation of the idea of the invention.

Embodiment 1 FIG. 1 is a cutaway perspective view showing a basic example of the invention.

The whole 1 is made of a soft polyethylene resin by a blow molding means, and the cooling medium liquid C (composition below) is almost completely filled inside the main body 2 having the disk-shaped enlarged portion 3. The rod-shaped portion behind the enlarged portion forms the grip portion 4. Then, heat welding 5 is performed at the rear end of the portion. The dimensions of each part in this example are almost the same as those already described in the section “Means for solving the problems” (paragraph 6).

[Composition of cooling medium liquid (unit:% by weight)] Propylene glycol 2 Sodium polyacrylate 0.2 Potassium chloride 3 Purified water 94.8

In use, after freezing in a freezer, it is inserted into the rectum from the anus so as to contact the external hemorrhoidal part. If desired, a hole may be bored in the heat-welded portion 5 and a string for assisting removal may be passed directly or through a ring.

Embodiment 2 FIG. 2 is a cutaway perspective view showing an improved example of that of FIG.

In the therapeutic device of this example, since the disk-shaped enlarged portion 3 expands in a leaking manner, a larger amount of cooling medium liquid can be accommodated as compared with the previous example, and a tapered portion of the enlarged portion. Since 3a adheres closely to the anus, it exerts a greater cooling effect on external hemorrhoids. The length of the grip portion 4 in this example is shorter than that in the previous example.

Example 3 FIG. 3 is a cutaway front view of an embodiment slightly different from those of the previous two examples, and FIG. 4 is a plan view of the same.

In the treatment tool of this example, the enlarged portion 3 has a substantially bulbous shape, and the heat-welded portion 5 at the rear portion thereof forms the flat gripping portion 4 (knob 7) via the collar portion 6. Therefore, this therapeutic device has a larger contact area with the external hemorrhoidal nucleus than that of the previous example, and even if it is inserted excessively, the collar 6 prevents it from immersing into the rectum.

Embodiment 4 FIG. 5 is a plan view of the heat-welding portion 5 of FIG. 2 to which a disc-shaped pressing body 8 is added, and FIG. 6 is a sectional view taken along line XX of FIG.

In the treatment tool of this example, since the disc-shaped pressing body 8 is further attached to the heat-welding portion 5 at the rear end of the gripping portion 4, when it is inserted, it is pressed by the fingertip via the top surface 8a of the 8 Not only is it easy to do, but excessive insertion is prevented by the pressing body 8. The pressing body 8 is joined to the completed heat-welded portion 5 by, for example, friction bonding means and pressure-bonding and joining a separately manufactured disc-shaped pressing body 8.

Embodiment 5 FIG. 7 is a cutaway front view showing still another example of the invention, and FIG. 8 is a partial side view showing a main part of FIG.

The treatment tool of this example is substantially the same as that of the second embodiment, except that a pair of protrusions 9 and 9 are formed on the grip portion 4. These projections are projections for engaging the forceps as described above (paragraph 10).

Embodiment 6 FIG. 9 is a cutaway front view showing still another example of the invention.

The treatment tool of this example is also essentially similar to that of the second embodiment, but unlike the same as that of the second example, a male screw 10 is formed around the grip portion 4, and the cap 11 cannot be re-opened. It is screwed onto and the liquid of the content cooling medium is sealed. The stepped portion 12 between the open end of the cap 11 and the holding portion base portion having a concave arc shape is also used for the forceps engagement. Incidentally, since the head of the cap 11 in this example is flat, it can be easily inserted into the rectum.
