Abstract

The present invention relates to a method for collecting debris and particles generated by cutting of an orthopedic cast bandage by an oscillating cast cutter, the method comprising applying a tape strip to the surface of an orthopedic cast to be cut, The tape strip includes a thick adhesive layer attached to the surface to be cut, the adhesive layer being thick and tacky to promote the capture of particles caused by saw blades when the cast material is cut, thereby resulting in the cutting process. The particles are attached to the adhesive material in the strip.

Description

Orthopedic cast dust collection method {METHOD FOR COLLECTING ORTHOPEDIC CAST DUST}

1 is a perspective view showing an embodiment of the dust collecting tape of the present invention before being applied to the cast material to be cut.

Fig. 2 is a perspective view of the dust collecting tape of the present invention applied to the cast material cut by the saw blade through the middle of the strip, showing the result of collecting dust generated by the saw blade.

The present invention relates to an adhesive tape used to collect dust particles generated during cutting of a cast article. More specifically, it relates to an adhesive tape used to collect dust particles when the orthopedic cast material is removed by cutting the cast with a motor driven cast saw. The material of the adhesive tape has a property of deteriorating aesthetics and sticking to dust particles which are unhealthy.

In the orthopedic field, it is widely used to add orthopedic cast materials to fix injured limbs or to remove broken bones. Fixed casts are usually removed after a treatment period. In the early days of the prior art, various structures of scissors or saws were used, which often caused serious problems with skin or soft tissue. More recently, vibratory round cast cutters are commonly used for the removal of cast bandages. However, they generate a large amount of dust, and these dusts fill up around them, deteriorating aesthetics and making them unhealthy.

Attaching a vacuum device to the height of the cutting blades of the cast cutter is a commonly used way to suck in the generated dust particles. However, the vacuum device is heavy, cumbersome and generates a lot of noise. In a treatment facility such as a hospital, when this noise is added to the noise of an electric cast cutter, it becomes very uncomfortable for the patient and bothers the patient. Moreover, additional equipment, auxiliary personnel and additional personnel are needed and therefore expensive.

Dust particles from removing cast bandages have been found to cause serious health problems. The amount of dust particles dispersed around can be significant. Dust from the fly plaster can cause serious injury to the eyes, bronchitis and other airborne diseases. Dust from fiberglass can cause dermatitis and can cause serious lung diseases, including lung cancer and mesothelioma. Therefore, it is desirable to remove the dispersed particles or to prevent the particles from dispersing in the original position.

Therefore, the technical object of the present invention is to make it possible to easily collect the dust generated in the cutting operation.

The present invention relates, in particular, to a tape of novel construction, which is attached to the surface of an orthopedic cast material and can remain in place during the cutting process. The composite structure of the tape has a central layer 1 of adhesive material, the main characteristic of which is that it is sufficiently elastic and adhesive to be coated over irregular surfaces or curved surfaces, and is a standard saw device commonly used in the art. Or it can be cut | disconnected by the cutter apparatus.

On both sides of the center layer of adhesive material are waxed or siliconized pressure-sensitive release paper layers 2, 3. These paper layers prevent the central layer of adhesive material from sticking to adjacent layers. These paper layers also prevent people at work from accidentally touching the adhesive surface. Protective wax paper layers 2, 3 become covers covering the adhesive side during storage.

In general, the thickness of the center layer 1 of the adhesive material is 4 mm. This is sufficient to keep the tape attached in place during the cutting process, and also flexible enough to penetrate irregularities on the surface of the cast material, but not flexible enough to create a sticky fluid bed or to soil the saw blade.

In practice, the thickness of the tape is determined by the number of cutting teeth of the saw blade and its running distance. A saw blade of a cast cutter that is commonly used vibrates at an angle of 5 degrees to 7 degrees. This is 3 mm in terms of depth. As the cutting process proceeds, the cutting teeth are always embedded in a central layer of adhesive material. Those skilled in the art will appreciate that the material of the central layer can be made of a variety of materials, including but not limited to hot melt and other polyurethane products. In addition, the adhesive material should not be cured when exposed to air, should be stable at room temperature and have a long shelf life. It should also be capable of withstanding temperatures typically between 150 and 180 ° F., caused by friction of the saw blade. Sticky materials should be avoided as they tend to soil saw blades or exhibit viscous changes at low temperatures.

In a preferred embodiment, the dust collecting tape can be supplied in one single strip of predetermined length, more conveniently stored and supplied in the form of a roll.

Prior to use, the attending physician removes the lower release paper 2 and attaches an adhesive layer to the area to be cut of the cast. Soft pressure on the strip ensures that the adhesive material penetrates irregularly on the fiberglass cast surface. The surgeon then removes the upper release paper, cuts through the adhesive layer 1 and the fiberglass layer 5 through the center of the strip and casts to the skin protective cotton layer (webrill) 4. Will be cut.

Other modifications may be made in the present invention, which also belongs to the spirit of the present invention.

According to the structure of this invention, the effect which can collect | acquire the dust etc. which generate | occur | produce in a cutting operation | work easily is acquired.
