Description

Antipruritic structure for plaster-covered limbs

The invention relates to the field of antipruritic structures, in particular to an antipruritic structure for plaster-coated limbs, which can be extended into gypsum to calm the skin in a cold manner to achieve an antipruritic effect.

Plastering is a common medical method used to fix fractures, ligament tissue damage, or limbs of surgical patients. Plastering is used to apply pressure to the affected limbs to prevent displacement of the wounds and promote healing. When a patient is cast, the most common condition is the itching of the skin in the plaster-covered area, in addition to the pain from the affected area and the pressure on the limbs. Due to the poor breathability of gypsum, it is easy to cause the skin sweat in the covered area to be difficult to remove, so it is easy to cause allergies and itchy skin problems, especially the elderly, those with allergies, those with diabetes, and those with abnormal liver and kidney function. Good hair. In order to eliminate the patient's itching and discomfort, the current common methods include scratching itching with a hand or a hard object such as a ruler, a pen, a rigid scratching device, or spraying an antipruritic spray, vaseline and lotion to reduce the discomfort.

However, the antipruritic effect on the skin in the plaster is different from the skin in the general open area. Because the plaster covers the injured limbs, care must be taken not to damage the skin during the scratching process to avoid proliferating wounds and other diseases. . In the current antipruritic method, if you pick your hands or scratch it with a hard object, it is easy to form pressure points and cause skin damage, and the hard object must reach into the plaster. If it gets stuck in the plaster, it will also compress the skin and cause damage. . On the other hand, in order to ensure that the plaster has sufficient fixing strength to the affected limbs, there is only a small gap between the plaster and the skin. The method of spraying antipruritic spray, vaseline and emulsion can reduce direct contact with the skin with hard objects. It may cause damage, but its implementation is extremely inconvenient and the antipruritic effect is not good. And spraying other external substances on the skin of the limbs of the affected area is also likely to cause adverse effects on the affected area.

In view of this, the research and development team gathered related experiences and conceived an antipruritic structure for plaster-covered limbs, which can achieve an excellent antipruritic effect while preventing skin damage.

An object of the present invention is to provide an antipruritic structure for plaster-coated limbs, which can gently and not hurt the skin, so that the itching sensation on the skin of the plaster-coated limbs can be eliminated.

It can reduce friction to prevent skin damage such as peeling, and reduce the adverse effects of wound hyperplasia on patients. Among them, these ice-cooled balls 12 can be made of materials that can have a temperature lower than the human skin under normal conditions or through cooling methods, such as metal, materials with high thermal conductivity, ceramics, etc., so that patients with gypsum can feel cold.

In order to facilitate the anti-itching structure 1 to penetrate into the plaster to achieve the anti-itching effect on the skin of the covered area by using the cold and rolling contact of the ice-cooling balls 121, the anti-itching structure 1 is slender as a whole. By holding the hand-held portion 10, the anti-itching portion 12 and a part of the middle portion 11 can be extended into the plaster to prevent itching.

In particular, the anti-itching structure 1 of the present invention aims to stop the plaster bag of a gypsum patient. Cover itching on the limbs to eliminate the discomfort of the patient, and based on the medical instructions for patients with plaster, that is, plaster-covered limbs are not suitable for directly scratching, scraping, or pressing hard to stop itching. Roller 121 replaces the method of directly scratching the skin to achieve the antipruritic effect by virtue of its cold and rolling contact characteristics, avoids the damage caused by pressing and rubbing the skin by rolling contact, and uses conventional techniques to press against the skin. The use of friction varies.

Preferably, since the distance between the plaster and the skin covering the limb is extremely small, it is disclosed in this embodiment that the thickness of the antipruritic portion 12 is between 0.5 and 1.45cm, so as to prevent the antipruritic portion 12 from being too thick and unable to extend. Into the plaster, or too thin, it is difficult to install the ice-cooled balls 121 and the structural rigidity is insufficient. After setting in the foregoing range, the anti-itching structure 1 is also easier to move in contact with the skin when placed in the plaster. In addition, in order to increase the contact area between the ice-cooled balls 121 and the skin in the gypsum to prevent the skin from being directly damaged by the friction of the surface of the anti-itchy part, the present invention also has further technical features.

That is, the total area and A of the ice-cooled balls 121 account for more than 25% of the area (BA) of the surface of the antipruritic portion 12 where the ice-cooled balls 121 are not provided. For example, as shown in this embodiment, when the ice-cooling balls 121 are disposed on one surface of the anti-itching portion 12 and the surface area thereof is B, the total area and A of the ice-cooling balls 121 occupies one of the anti-itching portions 12. About 27% of the area (BA) of the ice ball 121 is not provided on the surface. The area of the ice-cooling balls 121 refers to the round area protruding from the surface of the anti-itching part 12, and depending on the setting requirements, the ice-cooling balls 121 may use small-sized balls and be closely arranged to make the ice-cooling The total area of the balls 121 and A account for 30%, 50%, or 80% of the area (BA) of the antipruritic portion 12 where the ice-cooled balls 121 are not provided. In addition, in order to make the antipruritic structure 1 have a larger contact area with respect to the skin, when the distance between the adjacent ice-cooled balls 121 is D and the diameter of the ice-cooled balls 121 is R, it conforms to 1.5R. The relationship is ≦ D ≦ 2R, so that the cold rolling balls 121 have a large contact area with respect to the skin, which reduces the possibility that the skin directly contacts the surface of the antipruritic portion 12 and causes friction damage. Wherein, depending on the installation requirements, the distribution of the ice-cooled balls 121 may be a matrix, or arranged in a rectangle, a circle, etc. In this embodiment, the arrangement of the ice-cooled balls 121 in a rectangular shape is taken as an example. such cold when the balls 121 to the long side of the arrangement pitch D ₁ may 2R, are arranged in the short side may be a distance D ₂ 1.6R, so that the pitch of the balls 121 to cool these are arranged in different directions to the different state.

On the other hand, it is preferable that the vertical height of each of the ice-cooling balls 121 protruding from the surface of the anti-itching portion 12 is between In this way, it is more conducive to the rolling and rolling of the ice-cooled balls 121, which can have better contact performance with respect to the skin, and at the same time, has a better set strength, so as to prevent the ice-cooled balls 121 from falling off the itchy portion 12. In order to improve the stability of the user when handling, the hand-held portion 10 may be provided with a plurality of anti-sliding ribs 101.
