Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clavicle fracture fixation band used for fracture treatment by fixing the affected part of a fractured clavicle.

[Conventional technology]

The clavicle connects the sternum and the shoulder blades and has the function of preventing the shoulder from falling forward. When the clavicle is fractured, the shoulder loses its support and falls forward, causing the fractures to move inside each other (long axis shortening), and the central bone fragment (sternal side) moves upward, and the peripheral bone fragment (shoulder side) moves downward. Reduction of this fractured clavicle restores long-axis shortening by pulling the shoulders back and exposing the chest.
As a result, the shoulder is pulled upward, causing the inferior bone fragment to move upward, and the central bone fragment is then pressed from above to return it to its normal position. The clavicle is a bone that recovers extremely quickly, and even if it is slightly deformed, its function is not affected, so recovery can be achieved simply by maintaining the reduced position with a fixation band rather than safe fixation.

The basic structure of this fixed belt is sash-kake (8-shaped belt), in which the belt that comes out from the top of the backrest goes around the shoulders.
It returns to its original position through the axilla.
Although this structure has a strong force that pulls the shoulder backwards, the belt digs into the axilla, causing a lot of pain and, in some cases, causing blood vessel and nerve damage. Various efforts have been made, such as using materials with good elasticity, but nothing satisfactory has yet been achieved.

[The problem that the idea attempts to solve]

With conventional fixation straps, the reason why the pressure on the axilla increases in particular is that during wearing, the two belts connected to the upper part of the backrest gradually open to the left and right due to the tension applied to the belts. This is because the entire belt slides up along with the back rest. When the belt slides up in this way, the pressure on the axilla becomes large, and due to fluctuations in the fixation position of the belt, appropriate pressure is not applied to the fracture site, which poses a problem in treatment.

The purpose of this invention is to prevent the part of the tightening belt that touches the fracture site from shifting inward and outward or back and forth, so that the fracture site can be securely compressed and fixed.As a result, the compression force applied to the axillary region can be minimized, and the To provide a clavicle fracture fixing band which prevents the band from being misplaced and hitting the base of the neck.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a back rest and two fasteners whose upper ends are connected to the left and right sides of the upper part of the back rest, and whose lower ends are connected to the left and right sides of the lower part of the back rest, passing from the shoulder to the armpit. The upper end of each tightening belt has a substantially V-shape made of a material having greater rigidity than the tightening belt and extends along the tightening belt from the connection part of each tightening belt to the upper part of the back rest toward the shoulder. The belt is fixed to the upper part of the back rest via a tightening belt opening angle fixing plate having a shape such that the opening angle of both tightening belts at the upper part of the back rest can be maintained at a predetermined value by the tightening belt opening angle fixing plate.

The term "substantially V-shaped" as used in the present invention is not limited to the V-shape, but may also include a similar U-shape, or a shape that protrudes in the opening direction of the tightening belt.

[Effect]

In this invention, the back support is placed along the patient's spine, the tightening belt is extended above the back support, over the shoulders, and placed under the axilla so as to hit the clavicle fracture site, and is connected to the lower part of the back support. The parts of both tightening belts that protrude from the upper part of the backrest are uniquely fixed by a rigid tightening belt opening angle fixing plate, so that the opening angle of both tightening belts is constant. It has a certain value and remains stable without changing while being worn.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a developed view of one embodiment of the present invention, FIG. 1a is a front view thereof, and FIG. 1b is a rear view thereof.

The upper end 4 of a tightening belt 3 is connected to the upper part 2 on the left and right so as to extend slightly diagonally upward, and the lower end 5 is a free end and a hook-and-loop fastener 6 is attached to the end. A shoulder pad 7 is attached to a portion of the tightening belt 3 that corresponds to the clavicle, and has a wide enough to cover the clavicle and has an appropriate hardness so as to apply compressive force to the clavicle. This shoulder pad 7 may be formed integrally with the tightening belt 2, or may be formed separately so that it can be connected. Further tightening belt 2
A V-shaped tightening belt opening corner fixing plate 8 is attached to the connecting portion to the backrest 1. The enlarged front view and bottom view are shown in FIGS. 2a and 2b. This tightening belt opening angle fixing plate 8 is made of a material that is more rigid than the tightening belt and has a hardness that does not easily deform. It has an extending length and can be attached by being sewn into the tightening belt 3 and the backrest 1.

Rings 10 are attached to the left and right sides of the lower part 9 of the backrest 1, and the lower end 5 of the tightening belt 3 is inserted into these rings 10 and folded back, so that the hook-and-loop fastener 6 can be tied to the tightening belt 3. There is.

The tightening belt opening angle fixing plate may be U-shaped as shown in the front and bottom views of Figures 3a and b, or the part located in the center of the upper part of the back rest may be hollowed out downwards to compress the upper part of the back rest. Any shape other than V-shape or U-shape may be used as long as the shape does not cause pain and has a portion that protrudes in the opening direction of the tightening belt.

Next, a method of attaching this fixing band will be explained with reference to FIG. Note that FIG. 4a is a front view of the installed state, and FIG. 4b is a rear view thereof.

Place the backrest 1 on the patient's back so as to almost follow the spine, pass the tightening belt 3 from the upper part of the backrest 2 over the shoulders, and place the shoulder pad 7 over the clavicle fracture site to pass through the axilla; The lower end 5 of the tightening belt 3 is inserted into the ring 10 of the lower back support 9, and the hook-and-loop fastener 6 is tied onto the tightening belt 3 by applying tension so as to apply appropriate pressure to the fracture site. In this manner, both tightening belts 3 are fixed at the opening angle of the fixing plate by the tightening belt opening angle fixing plate 8 at the upper part of the back rest, and this opening angle is fixed to the opening angle of the tightening belt opening angle fixing plate 8 during use. 3 does not change even if forces are applied from various directions.

FIG. 5 is a developed view of another embodiment of the present invention.
Figure a is its front view, and Figure 5b is its rear view.

This embodiment differs from that shown in FIG. 1 in that the backrest is elongated and has a support, and that the tightening belt is divided into two.

Reference numeral 21 denotes a back support, which is elongated and made of a material that is flexible and has good cushioning properties at least on the side that touches the back, and a column 22 that is made of an elastic material on the outside, that is, on the opposite side to the side that touches the back.
is installed. The struts 22 may be sewn into the backrest, or a strut cover may be attached to the backrest so that the struts can be inserted therein so that the struts can be removed during washing.

Upper ends 25 of shoulder belts 24 are connected to the upper part 23 of the backrest 21 on the left and right so as to extend slightly diagonally upward, and the free ends of the shoulder belts 24 are provided with hook-and-loop fasteners 2.
6 is provided. Backrest 21 of shoulder belt 24
As in the case of FIG. 1, a V-shaped shoulder belt opening angle fixing plate 27 is attached to the connecting portion.

Rings 29 are fixed to the left and right sides of the lower part 28 of the backrest 21, and the lower end 31 of the axillary belt 30 is connected to the rings 29.
The lower end 31 of the axillary belt 30 can be connected to the back rest lower part 28 by inserting it into the axillary belt 30, folding it back, and tying the hook-and-loop fastener 32 provided at the lower end 31 onto the axillary belt 30. A shoulder pad part 33 is provided at the other end of the axillary belt 30, and this shoulder pad part 33 has a width that can cover the clavicle similarly to the one in FIG. It is hard and its outer surface is made of a material to which hook-and-loop fasteners can be attached.

The fixing band is attached as follows. The back rest 21 is placed on the patient's back so as to almost follow the spine, the shoulder part 33 of the axillary belt 30 whose lower end is connected to the lower part of the back rest 28 is placed on the fracture site, and the free end of the shoulder belt 24 is placed on top of the shoulder part 33 The hook-and-loop fastener 26 of the shoulder belt 24 is placed on the shoulder belt 24 in such a way that an appropriate compression force is applied to the fracture site by adjusting the mutual position and attachment angle of both, and the axillary belt 30 does not cause pain in the axilla. Shoulder part 3
3 Press and tie on top. Due to this binding, the shoulder belt 24 and the axillary belt 30 are integrated to form a tightening belt. In this embodiment, the shoulder pads are provided on the axillary belt side, but they may be provided on the shoulder belt side. In this embodiment, the tightening belt is divided into two parts, and the shoulder pad part is provided on either the shoulder belt or the axillary belt, so that the shoulder pad part can be applied freely to the appropriate position of the fracture site, and the patient can fracture the bone. Regardless of the location or body shape, both peripheral and central bone fragments can be reliably held, and the angle from the fracture site to the axilla can be adjusted to suit the body shape, resulting in extremely minimal pain in the axilla.Furthermore, the belt position This can be adjusted, so even if you increase the fixation force by making the part that hits your collarbone harder, it won't hit your axilla and cause pain. In addition, in this embodiment, by using a back support with pillars, a distance is secured between the connection points of the shoulder belt and the axillary belt to the back support, and the axillary belt can be fixed in a state almost perpendicular to the axilla, so that it is possible to secure the axillary belt almost perpendicularly to the axilla. There is less pain, and the belt does not shift and the distance does not change when you exercise or sleep, so the pressure on the fracture site does not change, and because it uses an elastic support, it fits the roundness of your back and allows you to exercise. It has the advantage of not causing any discomfort at times.

The material for the backrest is required to have cushioning properties to reduce pain by dispersing the compressive force as a core material, to prevent direct contact with metal fittings and supports, and to retain its shape so that it does not deform even after long-term use. Suitable are felt, thick (approximately 2 mm or more) non-woven fabrics, and other materials such as urethane foam (including compressed urethane foam), polyvinyl chloride foam, soft polyester foam, neoprene rubber foam, and natural rubber foam can also be used. can do. The cover material (surface fabric) must be comfortable to the skin so that it does not rub against the skin or cause a rash, and must have sweat absorption properties to prevent stuffiness and stickiness, such as cotton, rayon, acrylic, nylon, polyester, etc. Although knitted products can be used, it is preferable to use knitted fabrics made of sweat-wicking materials (product names such as "Control" and "Shield Sensor") or tubed knitted fabrics.

If the width of the tightening belt is narrow, it will not hold the collarbone firmly in place and will easily dig into the body. If it is wide, it will hit the neck and put a lot of pressure on the axilla, so the width should be between 3 and 7 cm. , non-stretchable material,
For example, polyester belts, cotton belts, acrylic belts, etc. can be used.

A suitable tightening belt opening angle fixing plate has a length of 7 to 10 cm in the part that is combined with the tightening belt. If this length is too long, it will not fit the curved surface of the shoulder when worn, making it impossible to obtain an appropriate therapeutic effect, and if it is too short, the tightening belt will not have a sufficient effect of fixing the opening angle. Width is 1/2 of the tightening belt
A width of about 3/5 is good; if it is wide enough to cover the entire width of the tightening belt, the contact and pressure of the tightening belt will increase and pain will increase; if it is too narrow, the fixing effect of the opening angle will be weakened. The thickness should be as thin as possible in order to prevent excessive pressure, reduce weight, workability, etc., but from the viewpoint of strength, 1 to 2 mm is usually suitable. The material is a non-stretchable sheet-like material with hardness that does not easily deform, such as plastic sheets or foam sheets of polyethylene, polypropylene, styrene, etc.
Vinyl chloride, urethane, etc. can be used. A soft material with cushioning properties, such as a soft urethane sheet or thick non-woven fabric, is pasted on the surface of this tightening belt opening angle fixing plate, and it is inserted into the bag-shaped tightening belt and attached to the back rest. It is preferable to do so.

The shoulder pads provided on the tightening belt can be made of the same material as the back rest.

A resilient material such as a leaf spring is used as the support that is attached to the backrest.

[Effect of idea]

According to the present invention, by attaching the tightening belt opening angle fixing plate across the tightening belt and the back rest and keeping the opening angle of the tightening belt constant above the back rest, (1) Since the fixed angle at the fracture site does not change, the tightening belt can always be held at the appropriate compression position on the fracture site.(2) A constant distance can be maintained between the neck and the tightening belt, It does not rub against the neck and cause problems such as pain. (3) Since the backrest does not slide up, the pressure on the armpits is reduced, resulting in a more effective effect.
