Description

Splint auxiliary device for preventing heel pressure ulcers and splint unit including the same

The present embodiments relate to a splint auxiliary device and a splint, and more specifically, to a splint auxiliary device for preventing the occurrence of pressure ulcers on the heel and a splint including the same.

A splint is a corrective device that immobilizes body parts for stability when trauma, fracture, dislocation, or sprain occurs. Medical splints include a method that uses a plaster bandage that is flexible before hardening but remains firmly fixed after hardening, and a method that places a support bar on the damaged body part and wraps it with a bandage.

When applying a splint, pressure is concentrated on a specific area and there is a risk of developing bedsores. Bedsores are caused by continuous or repeated pressure or friction, and the likelihood of occurrence increases because ventilation is difficult to achieve inside the splint. Preventing bedsores is most important, so you should change your position periodically to avoid long-term pressure, and using soft bedding or keeping it clean is also helpful.

The risk of developing bedsores increases when bones are close to the skin, and the heel is a typical area where bedsores occur. When applying a splint to the lower leg, there are attempts to prevent heel bedsores, such as placing a soft object on the heel area and wrapping a bandage, but most of them only disperse the pressure and have limitations that do not fundamentally remove the pressure.

The present embodiments were developed in the background described above and relate to a splint assist device that prevents heel bedsores by preventing pressure from occurring on the heel when fixing the lower leg with a splint, and a splint unit including the same.

According to the present embodiments, a fixed part supported on the back of the lower leg, a movable part connected to the bottom of the fixed part and supported on the heel, and a support force provided to the movable part in a direction toward the heel, the support force includes a removable support part, , a splint assist device in which the moving part retracts and is spaced away from the heel when the support force is resolved may be provided.

Additionally, according to the present embodiments, a splint unit including a splint aid may be provided.

According to the present embodiments, heel bedsores can be prevented by preventing pressure from occurring on the heel when fixing the lower leg with a splint.

According to the present embodiments, a fixing part 111 supported on the back of the lower leg, a moving part 112 connected to the lower end of the fixing part 111 and supported on the heel, and a supporting force on the moving part 112 in the direction toward the heel Provided is a splint auxiliary device 110 where the support force includes a removable support portion 113, and when the support force is eliminated, the moving portion 112 retreats and is spaced away from the heel.

Additionally, according to the present embodiments, a splint unit 100 including a splint assist device 110 is provided.

The splint unit 100 according to the present embodiments is fixed to the lower leg, including the splint auxiliary device 110 according to the present embodiments. According to one embodiment, the splint unit 100 includes a splint 120 and a splint auxiliary device 110, and the splint auxiliary device 110 may be located between the splint 120 and the lower leg. The splint 120 is not particularly limited in shape and type, such as cast type or semi-cast type. The splint 120 and the splint auxiliary device 110 can be, for example, wrapped with a bandage and firmly fixed to the lower leg. The splint auxiliary device 110 prevents pressure from being generated on the heel, thereby preventing the development of bedsores.

1 and 2 show the splint auxiliary device 110 and the splint unit 100 according to the present embodiments from the side. The splint auxiliary device 110 according to the present embodiments includes a fixing part 111, a moving part 112, and a support part 113.

The fixing part 111 is supported on the back of the lower leg (see reference numeral A). After the supporting force of the support part 113 is eliminated and the moving part 112 is separated from the heel, only the fixed part 111 remains in contact with the body. The fixing part 111 may be made of a material with a soft surface, such as sponge, silicone, or a fiber material, to reduce stress on the skin. However, the structure of the fixing part 111 does not change and maintains appropriate hardness to stably support the body. In particular, the fixing part 111 can firmly support the Achilles tendon.

The moving part 112 is connected to the lower end of the fixing part 111 and is supported on the heel (see reference numeral B). When the supporting force of the support part 113 is relieved, it is provided to be spaced apart from the heel. The fixed part 111 and the moving part 112 may be formed integrally or separately. Due to the holding force of the support unit 113, the front of the moving unit 112 is supported on the heel before applying the splint, during the application of the splint, and until the application of the splint is completed. When the support force of the support part 113 is resolved after completion of splinting, the moving part 112 retreats and the front part is spaced away from the heel. Accordingly, as shown in FIG. 2, an empty space is formed between the moving part 112 and the heel, and the heel takes the form of floating in the air, so no pressure is applied to the heel, thereby preventing the occurrence of bedsores. . The shape and method by which the moving part 112 retreats are not particularly limited.

The support part 113 provides support to the moving part 112 in a direction toward the heel, and the support force provided by the support part 113 to the moving part 112 can be resolved. The fact that the support force can be resolved means that not only the support force provided to the moving part 112 is removed, but also the support force provided to the moving part 112 is less than the level necessary for the heel to be stably supported by the moving part 112. This includes weakening. In order for the splint to firmly and stably fix the body, the support part 113 provides sufficient support to the moving part 112 and the heel is maintained supported on the moving part 112 until the splinting is completed.

The support part 113 is sufficient as long as it can provide a removable support force to the moving part 112, and its structure or shape is not particularly limited. The drawing shows an embodiment in which the support part 113 has a predetermined volume on the rear side of the moving part 112, but it is not necessarily limited to this and the support part 113 may be attached to the back side of the moving part 112. Alternatively, it may be located in front of the moving unit 112. In addition, the support force provided by the support part 113 to the moving part 112 is sufficient as long as it allows the moving part 112 to be supported on the heel and can be resolved, and its type or shape is not particularly limited.

According to one embodiment, the support part 113 is supported on the rear side of the moving part 112 and may provide support. That is, the moving part 112 is located between the support part 113 and the heel, and the support part 113 can provide support from the back of the moving part 112 to the front.

Referring to FIG. 3 , when the supporting force provided by the support part 113 is eliminated, the connection portion between the fixed part 111 and the moving part 112 may be folded or bent, and the moving part 112 may be separated from the heel. When the supporting force of the support part 113 is eliminated, the moving part 112 moves while the fixing part 111 is fixed and is spaced apart from the heel. When the support force of the support portion 113 is eliminated, the moving portion 112 moves in a direction away from the heel from its position before the support force was eliminated. The entire moving part 112 may move in a direction away from the heel, or only a portion of the moving part 112 supported by the heel may move in a direction away from the heel.

According to one embodiment, when the supporting force of the support part 113 is relieved, the connection portion between the fixed part 111 and the moving part 112 is folded and the moving part 112 can retreat (see (A) in Figure 3). ). The connection portion between the fixed part 111 and the moving part 112 may be made of a flexible material such as rubber or silicone, or may be connected by a mechanism such as a hinge. When the connection portion of the fixed part 111 and the moving part 112 is folded, the moving part 112 rotates as a whole with respect to the fixed part 111, as shown in the drawing, and the front of the moving part 112 is spaced away from the heel. It can take the form of

According to one embodiment, the moving part 112 has a restoring force in the direction opposite to the direction toward the heel, and when the supporting force of the supporting part 113 is resolved, the moving part 112 can retreat due to the restoring force. (Figure (See (B) in 3). The moving part 112 is made of an elastic material such as rubber, and may have a restoring force in a direction opposite to the direction toward the heel. The supporting force of the supporting part 113 acts on the moving part 112 in a direction that resists the restoring force of the moving part 112, and when the supporting force of the supporting part 113 is relieved, the shape of the moving part 112 is changed by the restoring force. separated from the heel. Due to the restoration of the moving part 112, as shown in the drawing, the moving part 112 is bent from the area adjacent to the fixed part 111 to the opposite end, and the front of the moving part 112 is spaced from the heel. can be taken.

According to one embodiment, the volume of the support portion 113 is reduced and the support force can be eliminated. That is, the support force provided to the moving part 112 may be provided by the force by which the support part 113 expands. And, the support force provided to the moving part 112 may be relieved as the support part 113 contracts. The support part 113 is located in a space having a predetermined volume, and support force can be provided to the moving part 112 by expanding the support part 113 in the space. When the volume of the support part 113 decreases and the support force is eliminated, the connection part between the fixed part 111 and the moving part 112 may fold, or the moving part 112 may retreat due to the restoring force of the moving part 112. there is.

Referring to FIG. 4 , the support part 113 includes a fluid 410, and the support force of the support part 113 may be provided by the hydraulic pressure of the fluid 410. The type of fluid 410 is not particularly limited and may be, for example, water or air. The support portion 113 may be a capsule or pocket that accommodates the fluid 410. As the fluid 410 is supplied to the support part 113, the support part 113 expands and support force may be provided to the moving part 112. And, after applying the splint, as the fluid 410 is recovered from the support part 113, the support part 113 contracts and the support force provided to the moving part 112 can be relieved. Although not shown in the drawing, fluid supply and recovery can be performed through a separate flow path connected to the support portion 113. When the fluid in the support part 113 is recovered and the support force is eliminated, the connection part between the fixed part 111 and the moving part 112 may be folded, or the moving part 112 may retreat due to the restoring force of the moving part 112. there is.

According to one embodiment, the support portion 113 may include an elastic body that provides support. The elastic body is supported on the moving part 112 and may provide support in a direction toward the heel. The type of elastic body is not limited and may be, for example, spring, rubber, etc. After completing the implementation of the splint, the support portion 113 is removed by releasing the support of the elastic body to the moving portion 112, removing or weakening the elastic force of the elastic body, or changing the direction in which the elastic force is provided to the moving portion 112. The support force can be resolved. When the support provided by the elastic body 520 is eliminated, the connection portion between the fixed part 111 and the moving part 112 may be folded, or the moving part 112 may retract due to the restoring force of the moving part 112.

Referring to Figure 5, the fixing part 111 includes an extension part 510 on which one end of the elastic body 520 is supported, and the elastic body 520 is between the extension part 510 and the moving part 112. It can provide support in a direction that pushes the moving part 112 from the extension part 510.

Referring to FIG. 6 , the supporting force of the support portion 113 may be relieved by electrical and/or magnetic signals. The splint assist device 110 according to the present embodiments may further include a signal generator that generates an electric and/or magnetic signal to relieve the support force of the support portion 113. According to one embodiment, the signal generated by the signal generating unit may be directly transmitted to the support unit 113. By a signal directly transmitted to the support part 113, for example, the volume of the support part 113 may be reduced or the elastic force of the elastic body of the support part 113 may be weakened and the support force may be eliminated. Alternatively, according to one embodiment, the signal generated by the signal generation unit 610 may not be directly transmitted to the support unit 113. The signal generated by the signal generator 610 may be transmitted, for example, to a device for recovering fluid from the support portion 113.

According to the splint assist device and splint unit having such a shape, heel bedsores can be prevented by preventing pressure from being generated on the heel when fixing the lower leg with a splint.
