Body protection pad that can be vacuum shaped and reused

The invention relates to a limb protection pad, in particular to a limb protection pad which can be vacuum shaped and reused, so that the user can stably surround the limb protection pad and abut on a limb surface (eg, head, foot and foot fracture) After the surface of the neck or sprain, only the air in the limb protection pad needs to be withdrawn, and the limb protection pad presses a plurality of particles filled therein to make the particles abut each other, thereby Assisting the limb protection pad with the contour of the limb to form a pseudo-solid shape (the hardness or elasticity depends on the amount of air extracted) to protect the limb (eg, absorbing and slowing the impact of external force on the head, The fracture of the hand and foot can be regenerated after obtaining a stable fixation position, or the neck and neck sprain can get enough support).

According to the statistics of the World Health and Medical Organization, at least about 10% of the world's population will be "gypsum" due to limb fractures or surgery, although "plaining" is a common and not particularly surprising thing. However, the patient must still be mentally prepared and willing to take some time to adjust to it and understand it so that he can successfully pass the day of gypsum treatment.

Generally speaking, the physician will select the most suitable gypsum material according to the actual injury situation of the patient. It may be plaster cast or synthetic or resin cast made of gypsum powder, among which gypsum powder gypsum It is made of gypsum powder plus gauze; resin gypsum is made of glass fiber plus PU resin. However, no matter which gypsum material is used, in the first week of gypsum treatment, the injured limb will usually continue to swell, causing the gypsum to be too tight, resulting in poor blood circulation and pain; the second week, when the patient begins to swell When you dissipate, you will feel that the plaster is too loose and lacks a fixed effect. Therefore, at the beginning, the patient needs a few days to adjust to it. A few days before the plaster is applied, the patient will always feel it, and because the patient may or may not be able to do it before the injury. Things must be slowed down in order to slowly adjust and match their physiological limitations. During the activity, they will not cause damage to the affected parts. Any negative impact. In addition, within the next two weeks, the first visit is still needed. However, when the patient encounters the following conditions, he/she should immediately return to the doctor for proper treatment after the diagnosis: 1. When the affected limb is in pain; Feel that the plaster mold is too tight and sad; 3, the plaster mold is slowly loose, cracked or cracked; 4, when the plaster feels the pressure of compression or friction; 5, the skin next to the plaster mold feels continuous When it is cold or white, blue; or 6, when the finger or toe of the plaster mold position, there is pain, numbness or persistent tingling.

After a certain period of time, Dr. Yan diagnosed that the fracture site of the patient had matured due to the callus, and when it was completely restored, a specially designed plaster saw was used to remove the plaster mold from the affected limb. This kind of plaster saw has special The design only cuts the anhydrite without cutting the soft skin. The process of removing the plaster mold is fast and painless. However, the potential danger still exists. Therefore, the patient must be able to fully cooperate with the doctor to be dangerous. Minimized.

According to the above, in the days of gypsum treatment, in addition to the above problems and many discomforts caused by the plaster mold on the affected limb, after the completion of the treatment, a large number of the removed plaster molds become medical waste. A significant burden and a huge waste of resources.

Therefore, how to design a limb protection pad, in addition to allowing the user to stably surround the limb protection pad and abut against the surface of the affected limb (eg, the surface of the fracture of the hand and foot), only need to be in the limb protection pad The air is drawn out, so that the limb protection pad presses a plurality of particles filled therein, so that the limb protection pads are molded into a pseudo-solid with the contour of the affected limb after the particles are abutted against each other (the The hardness or elasticity depends on the amount of air extracted. In addition, the fractures of the hands and feet can be regenerated after obtaining a stable fixed position. After the gypsum treatment is completed, the patient only needs to introduce air into the limb protection pad. The particles filled in the limb protection pad are loose and returned to a soft state, so that the patient can remove the limb protection pad, inspect, clean, apply medicine, etc., and can recover according to the initial self. The contour of the affected limb, re-adjusting the shape of the limb protection pad, so that the affected limb can continue to obtain comfortable, good and sufficient support during the rehabilitation process, until it is completely healed, which becomes the important point of the present invention. problem.

In view of the fact that the plaster can not be shaped for the contour of the affected limb and cannot be repeated Using the above-mentioned shortcomings, the inventor has, after many years of practical experience, after many experiments and researches, finally designed a vacuum-shaped and reusable limb protection pad of the present invention, which can effectively solve the conventional plaster. The use of many problems, and allows the user to reuse the limb protection pad during the treatment of the affected limb, or during the rehabilitation of the affected limb, or during the protection of the limb. And by re-adjusting the body protection pad to shape the limb, the limb can get the best treatment, rehabilitation and protection.

The object of the present invention is to provide a limb protection pad which can be vacuum shaped and reused. The limb protection pad comprises an inner bag, a plurality of particles, an outer bag, a gas nozzle and at least one tightening element, wherein the inner body The bag is made of a gas permeable material, the periphery of which is sealed to form a first accommodating space therein, and the inner side surfaces of the inner bag are respectively disposed at a position spaced apart from each other and are respectively provided with a positioning component, and the positioning is respectively provided. The component can divide the first receiving space into a plurality of positioning spaces, and the adjacent positioning spaces are separated from each other but communicate with each other, so that the section of the first receiving space is always maintained at a predetermined flatness The particles are filled in the positioning spaces of the inner bag and are movable between the positioning spaces, and the particle diameter of each of the particles is larger than the gas permeable aperture of the gas permeable material; a gas impermeable material, the periphery of which is hermetically sealed to form a second receiving space therein, the second receiving space for receiving the inner bag, the outer bag surface corresponding to the second receiving space Location is open Opening, the opening is in communication with the second receiving space; the bottom periphery of the nozzle is hermetically sealed at a position corresponding to the opening of the outer bag surface, and an air is disposed in the nozzle a passage for allowing an air suction device (eg, a vacuum cleaner) to evacuate the accommodation space through the air passage; the tightening member (eg, a tightening strap or a devil felt) can stably stabilize the limb protection pad Surrounding and abutting on the surface of a limb (such as a head, a broken foot or a neck and a sprain), and adjusting the limb protection pad to cover the tightness of the limb.

In this way, after the limb protection pad is stably covered on the surface of the limb, the user only needs to use the air suction device to evacuate the outer bag through the air passage. At this time, the inner bag can be completely prevented. The particles filled therein are sucked out, so that only the air in the first receiving space and the second receiving space is extracted by the air extracting device, causing the outer bag to deform inward, and the inner bag is pressed and The particles are filled therein such that the particles abut each other, thereby enabling the limb protection pad to be molded into a pseudo-solid shape (the hardness or elasticity depending on the degree of vacuum) along the contour of the limb to protect the Limbs, such as: absorbing and slowing the impact of external forces on the head, causing fractures of the hands and feet Regenerate after obtaining a stable fixed position, or get enough support for the neck and sprain.嗣, when the user does not need to use the limb protection pad, only the air is introduced into the outer bag, so that the particles filled in the inner bag can be loosened, thereby making the limb protection pad soft and convenient. Collection and reuse for the next time.

Thus, after the particles 40 are filled in the positioning spaces 331 of the inner bag 30, the particles 40 can move within the positioning spaces 331, but the positioning elements 35 make the first The section of the accommodating space 33 is always maintained at a predetermined flat shape. Therefore, the particles 40 are evenly dispersed to the positioning spaces 331 so that the positioning spaces 331 are maintained at a relatively uniform thickness. All piled up in one place. Moreover, since the particle size of each of the particles 40 is greater than the gas permeable aperture of the inner bag 30, the particles 40 can only move in the positioning spaces 331 without being displaced outside the inner bag 30. According to the above description, it is only a preferred embodiment of the present invention. The positioning component 35 of the present invention is not limited to the line body when actually applied, and includes With the body, other soft and hard connectors or positioning points, according to those skilled in the relevant art, after the technical content of the present invention is applied, the positioning elements 35 are changed to other tapes or soft and hard connectors. Instead of, or instead of being replaced by a positioning point of zero length (the inner side of the inner bag is directly connected), the adjacent positioning spaces 331 are separated from each other but communicate with each other, and the section of the first receiving space 33 is always Maintaining the predetermined flat shape should not deviate from the protection scope of the positioning member 35 of the present invention.

Referring to Figures 1 and 2, the outer bag 10 is made of a gas impermeable material (e.g., an air impermeable plastic film), and its periphery is hermetically sealed to form a second receiving space therein. The second receiving space 13 is configured to receive the inner bag 30. The surface of the outer bag 10 defines an opening 14 at a position corresponding to the second receiving space 13. The opening 14 is connected to the second receiving space. 13 is connected to each other; the gas nozzle 20 includes a mouth holder 21 and a lid body 23, the mouth holder 21 is made of a gas-impermeable material, and the bottom periphery of the nozzle holder 21 is hermetically sealed in the outer bag 10 An air passage 211 is defined in the nozzle seat 21 to allow the air passage 211 to pass through the air passage 211 to the second receiving space 13 and the position corresponding to the opening 14 in the outer surface. The first accommodating space 33 is evacuated, and the cover body 23 can be closed to the top of the mouth base 21 to hermetically seal the air passage 211; the tightening member 15 can be a tight band, the bundle The two ends of the tight band are respectively firmly connected to the corresponding portions of the limb protection pad A, so that the limb protection pad A can stably surround and abut on a limb B ( : the surface of the head, the fracture of the hand and foot or the sprain of the neck and the waist), and the limb protection pad A is adjusted to cover the tightness of the limb B, and the particles 40 filled in the inner bag 30 can follow The limb B contour is positioned in the positioning spaces 331.

Thus, as shown in FIGS. 1 and 2, when the limb protection pad A is stably surrounded and abuts against the surface of the limb B, the user only needs to use an air suction device (eg, a vacuum cleaner) to pass through the The air passage 211 is configured to evacuate the outer bag 10. At this time, since the inner bag 30 can completely prevent the particles 40 filled therein from being sucked out, only the first receiving space 33 and the second receiving portion are provided. The air in the space 13 is drawn by the air extracting device, causing the outer bag 10 to deform inwardly, thereby pressing the inner bag 30 and the particles 40 filled therein so that the particles 40 abut each other, The limb protection pad A can be molded with a pseudo-solid shape (the elasticity or hardness depends on the degree of vacuum) to protect the limb B, such as: absorbing and slowing the impact of external force on the head, and the hands and feet The fracture can be regenerated after obtaining a stable fixation position, or the neck and neck sprain can get enough support. When the user does not need to use the limb protection pad A, only air is introduced into the outer bag 10, That is, the particles 40 filled in the inner bag 30 can be loosened, and the limb protection pad A can be restored to a soft shape for convenient collection and reuse for the next time.

In other embodiments of the present invention, as shown in FIG. 2, the gas nozzle 20 can also be designed as a one-way check valve or a gas valve according to actual needs, and the one-way check valve still includes an airtight seal. a valve 22, which is made of a gas impermeable material (such as an air impermeable plastic material), and is movably mounted in the air passage 211 to pass through the air passage 211 at the air suction device. When the first accommodating space 33 and the second accommodating space 13 are evacuated, the airtight valve 22 may be unidirectionally opened. Otherwise, the air pressure outside the outer bag 10 is equal to or larger than the first accommodating space 33. The airtight valve 22 automatically and hermetically closes the air passage 211 when the air pressure in the second receiving space 13 is; the air valve can be opened or closed to make the air passage 211 conductive or non-conductive. State.
