That is, the self-adhesive layer 20 in which the mono yarns 20a or the metal yarns 20b are woven in a velvety ring structure at the upper end (outer surface opposite the skin) and the lower end (skin contact surface) of the mesh layer 10. Among them, the self-adhesive layer 20 formed on the upper end of the mesh layer 10 is to increase the area in contact with the orthopedic splint (gypsum bandage or hydrosetting cast tape, etc.) to be subsequently performed, even in the patient's many movements. The function of preventing the separation from each other, even during the procedure can maintain the surgical splint of the splint by the self-adhesive layer, and the self-adhesive layer 20 formed on the bottom of the mesh layer 10 is woven surface It maintains its elasticity and keeps tightness, improves breathability, and facilitates the discharge of moisture (sweat) to prevent secondary infections such as sores and odors.

Thereafter, the cast skin protection bandage 100 of the present invention inserted into the affected part of the arm or leg is wound with a plaster bandage or a hydrosetting casting tape (hydraulic polyurethane splint) and the like, thereby completing the Gibbs procedure.

Here, another embodiment of the fitted skin protection bandage of the present invention will be described in detail with reference to the accompanying drawings.

3A and 3B are schematic views illustrating a fitted skin protection bandage according to another embodiment of the present invention.

Fitted skin protection bandage 200 according to another embodiment of the present invention is a mesh layer 10 woven mono mesh of two or more stages of the mesh structure, and a mono yarn (top or bottom, top and bottom of the mesh layer) 20a) or the self-adhesive layer 20 in which the metal yarn 20b is woven in a velvet-shaped ring structure, and woven into a predetermined shape in the mesh layer 10 along its longitudinal direction to prevent antibacterial, anti-odor and anion radiation. Skin protection bandage fabric is the same as the above embodiment in that the use of a skin protection bandage fabric consisting of a functional yarn 30 to be woven in a flat state, in this flat state Woven skin protection bandage fabric is characterized in that it is bonded by a joining means to be cut into a predetermined length and width to be cylindrical to be fitted to the affected part.

That is, as shown in Figure 3a attached skin protection bandage 200 according to another embodiment of the present invention folded the skin protection bandage fabric in half along the width direction, then bonded the both ends It is made into a cylindrical shape that can be joined by means.

Or, as shown in the accompanying Figure 3b is fitted skin protection bandage 200 according to another embodiment of the present invention, after superimposing two sheets of the skin protection bandage fabric to each other, the two ends of each sheet as a bonding means It is made of a cylindrical shape that can be joined together.

Thus, the fitting skin protection bandage 200 according to another embodiment of the present invention made of a cylindrical by the joining means is also produced in a continuous manner while being bonded in a cylindrical shape in the production line, as shown in Figs. 1 and 2 ( As shown in a), a predetermined length is rolled on a roll to produce a product.

Similarly, after the cut-out type skin protection bandage 200 according to another embodiment of the present invention is cut to fit the affected size of the arm or leg, the affected part of the arm or leg as shown in (c) of FIGS. 1 and 2. Since it is only necessary to insert into the body, as in one embodiment, the operator can be provided with the convenience of the procedure, and the patient can be provided with various skin protection functions (ventilation, antibacterial, deodorant, sweat release, etc.) and at the same time have a mesh structure and elasticity. It can provide comfort without any foreign object.

On the other hand, as the bonding means for bonding the skin-protective bandage fabric in a cylindrical shape, any one selected from a sewing machine, an ultrasonic device, a high frequency device, a thermal bonding device, a double-sided tape, and an adhesive may be used.

In the case of using the sewing machine (not shown), there is a disadvantage in that a bonding line is formed at the bonding portion of the skin-protective bandage fabric, but in the case of using the ultrasonic device, the bonding line is hardly generated at the bonding portion of the skin-protective bandage fabric. Most preferably, an ultrasonic device is used as the bonding means.

That is, by passing both side ends, which are the joint portions of the skin-protective bandage fabric, at a constant speed to the ultrasonic irradiation part of the ultrasonic device, ultrasonic vibration is applied to the joints of the skin-protective bandage fabric, whereby the joints of the skin-protective bandage fabric are It can be easily bonded without the creation of a bonding line, and eventually it is possible to provide a cylindrical fitting skin protection bandage 200 with a beautiful appearance.

Here, look at in detail the method of manufacturing the fit-type skin protection bandage according to the present invention using ultrasonic waves.

5 and 6 are schematic views illustrating a method of manufacturing a fitted skin protection bandage according to the present invention using an ultrasonic apparatus.

The ultrasonic equipment 50 provided to manufacture the fitted skin protection bandage of the present invention is an ultrasonic oscillator 52 (AMP), the vibrator 54 and the horn 56, and the ultrasonic welding of the fitted skin protection bandages. The cutting blade 58 which cuts along the fusion surface is comprised.

Referring to the arrangement of the ultrasonic equipment 50, as shown in the accompanying FIG. 5, the ultrasonic oscillator 52 and the vibrator 54 are connected so as to exchange signals, and the horn 56 on the vibrator 54 It is integrally inserted and coupled, the cutting blade 58 is disposed on the upper surface of the horn 56.

At this time, the operating frequency of the ultrasonic oscillation amplifier 52 for manufacturing the fitted skin protection bandage is applied at 5kHz ~ 60kHz, preferably 20kHz, the output is 200Watt ~ 8000Watt, preferably 3000 Watt, input power AC220V / single phase, 50 ~ 60 Hz.

In addition, the frequency of the vibrator 54 and the horn 56 for manufacturing the fitted skin protection bandage is applied at 5kHz ~ 60kHz, preferably 20kHz, because the skin protection bandage fabric as follows This is to facilitate the melting of the junction part by frictional heat by ultrasonic vibration energy.

Accordingly, the junction portion of the skin-protective bandage fabric is passed between the horn 56 and the cutting blade 58 along the traveling direction indicated by the arrow of FIG. 5, wherein the vibrator 54 is formed by the ultrasonic oscillator 52. Is finely vibrated up and down, and due to the vibration is bonded by the cut portion of the skin protection bandage fabric by the friction of the horn 56 and the cutting blade 58 is fused.

That is, since mechanical vibration energy is transmitted from the ultrasonic oscillation amplifier 52 to the vibrator 54 and the horn 56 to generate strong frictional heat at the joint of the skin protection bandage fabric, the joint of the skin protection bandage fabric is melted and bonded. At the same time, the remaining piece of fabric except for the portion that is melted and bonded at the same time is to be cut off by the cutting blade (58).

On the other hand, the cutting blade 58 is a disk shape, while pressing the joint of the skin protection bandage fabric and serves to cut off the rim portion, the edge of the edge of the blade as shown in Figure 6 attached to the radius of curvature ( It is preferable to use one formed with an oval cross section having R) of 0.1 to 1.0. If the width is less than 0.1, the bonding area of the skin-protective bandage fabric is too small to bond well. This is because the junction width becomes too large to provide a foreign body feeling to the skin.

The process of manufacturing the fitted skin protection bandage of the present invention by such an ultrasonic apparatus will be described in more detail as follows.

First, an electrical signal of 50 to 60 Hz is converted into an electrical signal of 20 kHz (or 35 kHz) by the ultrasonic oscillator 52, and the voltage at the input is generally AC200 to 240 V, but inside the ultrasonic oscillator 52 It is amplified close to 1000V and transmitted to the vibrator 54.

Next, the 20 kHz (or 35 kHz) electric signal amplified by the ultrasonic oscillator 52 is transferred from the ultrasonic oscillator 52 to the vibrator 54 and converted into mechanical vibration energy.

At this time, the piezoelectric element embedded in the vibrator 54 changes the electrical signal into mechanical vibration energy, the dimension (thickness) of the piezoelectric element changes when the AC voltage is supplied. Expression.

Accordingly, the 20 kHz vibrator 54 generates 20,000 vibrations per second, and the vibration energy is transmitted to a horn 56, which is a kind of resonance body.

Therefore, a strong frictional heat is generated at the junction of the skin-protective bandage fabric by the vibration energy transmitted to the horn 56, and the temperature of the frictional heat is raised to a temperature for instantaneously melting the skin-protective bandage fabric, and at the same time the cutting The blade 58 presses the joints of the skin-protective bandage fabric, so that the joints of the skin-protective bandage fabric are melted and joined, and at the same time, the remaining cut edge fabric except for the joined portion is rotated and driven. 58) is cut and removed, and is manufactured with a cylindrical fit skin protection band that can be easily inserted into the affected arm or leg.

As described above, according to the present invention, by preparing a skin-protective bandage in which a two-stage mesh layer structure woven with mono yarns and various functional characteristics such as antibacterial, anti-odor, and sterilization are manufactured in a cylindrical shape, orthopedic splints By allowing the user to simply fit the arm or leg for the purpose of skin protection before the procedure, the operator may be provided with the convenience of the procedure and the patient may be provided with various skin protection functions and comforts.
