TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical splint used for a cast, and more particularly to a medical splint having excellent air permeability by using a nonwoven fabric and preventing infection from an affected part by an antibacterial treatment of a part contacting the affected part. About splint.
[0002]
[Prior art]
A splint is commonly used for bone injuries and fractures or joint injuries due to various accidents. That is, a splint is used to partially or totally tie an affected part, such as a fractured part, in order to join a bone having a fracture or Reto or fix an injured joint.
For this purpose, a commonly used casting method is to wrap a bandage coated with a gypsum material around the injured area. Such a casting method can effectively wrap the wound site at the time of winding the gypsum bandage around the fracture site, but after the gypsum material hardens, the gypsum material shrinks and floats from the injured site. was there. If a gap is formed between the fracture site and the splint, the splint cannot effectively fix the injured site, thereby causing the affected area to flow and hinder the treatment. In addition, this method requires a considerable amount of time in bandaging, in order to wrap the affected area until a sufficient thickness is obtained. In addition, the bandaged area has poor ventilation, especially in the summer season when sweating increases. In addition, in the case of fracture, a splint must be worn for a long period of time, usually about 8 weeks. In summer, pruritus and other problems may occur.
In order to solve these various disadvantages, splints have been developed and used as shown in FIGS. A glass fiber containing a known type of hardened body is provided inside the splint. An endothelium (2) is provided inside the glass fiber (1), that is, at a position where the fracture site of the patient contacts. Further, an outer skin (3) is provided outside the glass fiber (1).
When a part such as an elbow or a knee is wound on the splint configured as described above, it is inevitable that a wrinkle (4) occurs as shown in the figure. That is, a wrinkle is naturally formed by the thickness of the glass fiber (1). If such a splint becomes inferior in moldability that can be wrapped well along the bent shape of the injured part, as described above, the splint floats from the injured part, and The site will not be able to be tightly anchored, thus adversely affecting the treatment of the fracture. In addition, the splint shown is made of glass fiber and cannot be incinerated, so that the environment is destroyed or the dust of the glass fiber itself causes respiratory diseases and pruritus. Even with the splint having such a structure, the problem of securing the air permeability has not been solved.
As a further problem, the endothelium adhered to the affected area contains various bacteria, and there is a disadvantage that such bacteria invade the affected area, delaying treatment and causing various diseases.
[0003]
[Problems to be solved by the invention]
The present invention has been devised in order to solve the above-mentioned drawbacks, and an object of the present invention is excellent in moldability and air permeability, can be fixed to an affected part in close contact, and can prevent infection by various bacteria. To provide medical splints.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the medical splint of the present invention comprises an antimicrobial skin composed of a multilayered polypropylene non-woven fabric to which an antimicrobial agent is added, and a moisture hardener. An outer skin composed of an added polyester (polyester) and having a plurality of vent holes and an outer skin having an adhesive means attached to the antibacterial skin at an edge portion which is composed of a divided microfine yarn and is adhered to an edge portion thereof. It is characterized by.
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the operation and effect of each component will be described in detail with reference to the accompanying drawings through preferred embodiments of the medical splint according to the present invention.
FIG. 3 is a perspective view showing a medical splint according to one embodiment of the present invention, FIG. 4 is an exploded perspective view of a medical splint according to one embodiment of the present invention, and FIG. FIG.
As shown in the figure, the medical splint according to one embodiment of the present invention has a non-woven fabric made of polypropylene having a plurality of layers, an antimicrobial agent is added thereto, and an antimicrobial skin (5) covering the affected part, and a polyester (polyester). ), A moisture hardening agent for hardening moisture is added, and the cured skin (6a) is formed. The hardened skin (6, 8 ') is adhered to the edge of the antibacterial skin by adhesive means (8, 8'). The outer skin (7) covering in order to fix the affected area in layers.
The medical splint thus constructed according to one embodiment of the present invention is tightly adhered to the affected part before it is hardened by the above-mentioned water hardening agent which absorbs water from a method of dipping in water and contains water, and is bandaged. It is fixed by such as. As the moisture curing agent, a polyurethane resin is preferably used.
At this time, the antibacterial skin (5) forms a layer with a plurality of nonwoven fabrics so that water can quickly pass through the antibacterial skin (5) to the hardened skin (6). A large amount of water can be absorbed, and after the curing agent absorbs water, air flows between the nonwoven fabrics. In addition, the antibacterial agent added to the antibacterial skin (5) prevents the growth of harmful bacteria and, after the hardened skin (6) is hardened, prevents any more moisture from penetrating into the skin and causes an unpleasant odor. Does not cause discomfort. The antimicrobial agent added to the antimicrobial skin (5) is preferably arbekacin or zinc omadine, and other antimicrobial agents that can be directly used on the skin may be used.
A vent (6a) is formed in the hardened skin (6), and after the hardening agent is in close contact with the affected area, it hardens quickly, and even in a bent part such as an elbow or a knee, from a conventional medical splint. Adhered without generating wrinkles as seen.
The outer skin (7) is made of divided microfine yarns, preferably a knitted fabric made of divided microfine yarns of polyamide and polyester. Adhesive means (8, 8 ') which are adhered to the edge of the antibacterial skin (5) and which integrally fix the antibacterial skin (5), the hardened skin (6) and the outer skin (7) are provided on the edge of the outer skin (7). The bonding means (8, 8 ') are preferably made of double-sided tape.
Another embodiment of the medical splint of the present invention is shown in FIG.
As shown in the figure, a medical splint in which the antibacterial skin (5), the hardened skin (6) and the outer skin (7) are sequentially layered can be manufactured so as to be used for a fractured waist region (9). .
The antibacterial effect of the antibacterial skin was requested by a FITI TESTING & REASERCH INSTITUTE, a government-approved institution, and an experiment was conducted as in the following examples.
Example 1
[experimental method]
As shown in Table 1, 1.6 * 10 ⁵ bacteria (Staphylococcus aureus ATCC 6538) were respectively introduced into a polypropylene nonwoven fabric and a polypropylene nonwoven fabric containing arbekacin as an antibacterial, and the bacteria remaining after 18 hours passed. Was detected. In this way, 1.4 * 10 ⁵ other bacteria (Klebsiella pneunoniae ATCC 4352) were introduced and the antibacterial test was repeated.
[Experimental result]
Eighteen hours after the bacteria were injected, the number of bacteria in the polypropylene nonwoven fabric increased to 6.6 * 10 ⁶ from the first experiment, and the number of bacteria increased in the polypropylene nonwoven fabric containing Arbekacin (10 or less bacteria). In the next experiment, the polypropylene nonwoven fabric had 5.2 * 10 < ⁶ > bacteria, and the polypropylene nonwoven fabric containing Arbekacin also had fewer bacteria than 10 bacteria.
The experimental results are shown in Table 1 below.
【table 1】

[0005]
【The invention's effect】
Since the nonwoven fabric containing the antibacterial agent comes into contact with the skin, the medical splint according to the present invention as described above can prevent infection by harmful bacteria and prevent pruritus. The hardened skin has ventilation holes, and the outer skin is made of divided ultrafine yarns, so that even after hardening, air permeability is improved and a comfortable state can be maintained.
