Fiberglass bandage can easily deal with fracture | KENJOY

People may cause bone injuries by accidents in daily life, walking and exercise. Production accidents, traffic accidents and wars even cause injuries, which make part of the injured body lose motor function and affect people's normal life, which should be treated as soon as possible.

Medical bandages play a temporary supporting role in the treatment of bone trauma, protect the patient's bone and soft tissue, and reduce pain, swelling and muscle spasm. In addition, it can also be used in surgery and orthopedic surgery where fixed support is needed.

There are many disadvantages in traditional plaster bandages

In the past, most of the common bandages were cotton bandages coated with plaster, but this kind of bandage had a variety of disadvantages in use.

1. First of all, due to the limited strength of cotton tape, so the use of this bandage must be multi-layer use, so bandage (fixed) after a larger volume, especially in winter will affect wear.

2. Secondly, the plaster bandage is not breathable after being bandaged and fixed, especially in hot weather, where it is not allergic, itching, or even cause bacterial infection.

3. Plaster bandage is afraid of water, and the wet strength of the plaster bandage is reduced or even can not play a fixed supporting role, which brings a lot of inconvenience to the life of patients.

4. After using this kind of plaster bandage fixation, the patient (doctor) wants to see the fracture joint, must first open the fixed plaster bandage body, can carry on the fluoroscopy to take the X-ray film, not only inconvenient but also increases the patient's economic burden.

The advantages of warp knitted fiberglass medical bandages are remarkable

Glass fiber has high strength, non-toxic and no harm to human health. in the 1980s, developed countries began to use it as medical bandages, but in recent years, domestic glass fiber polymer medical bandages have been used in many hospitals and developed well. It is increasingly recognized by the majority of doctors and patients. Compared with the traditional plaster bandage, its advantage is significant!

1. High intensity. Its strength is more than 20 times that of plaster bandage, only 2-3 layers are needed for bandaging and fixation of unsupported parts, and only 4-5 layers are needed for bandaging and fixation of supporting parts. Because of its small size, it will not affect what patients wear in winter and cold areas.

2. Light weight. The bandage and fixation of the same site is 5 times lighter than that of cotton plaster bandage, so it can reduce the additional burden on the fixed site of patients.

3. The operation is simple and convenient. It only takes 5-8 minutes to solidify and play a fixed supporting role.

4. It's breathable. It can avoid skin allergy, itching and infection caused by bandaging and fixation in summer.

5. Not afraid of water and moisture. Patients can take a bath, which is especially important for patients in summer.

6. The X-ray transmittance is 100%. It is not necessary to remove the bandage when patients take X-rays, which can not only facilitate both doctors and patients, but also reduce the economic burden of patients.

Three breakthroughs have been achieved in the development of medical fiberglass bandages made of fiberglass warp knitted fabric: first, the technical breakthrough of glass fiber looping. The second is the technological breakthrough of polyurethane polymer materials. The third is the breakthrough in the application of traditional industrial glass fiber composite to the medical field.

The difficult problem of glass fiber braided elastic fabric is that the folding resistance and wear resistance of glass fiber is very poor, and this kind of fabric requires that the fiber can resist folding, otherwise it can not form a circle and can not produce elastic braided fabric.

Analysis from the aspect of materials: the company proposes to carry out the research on the strength of glass fiber ring, according to the principle that the smaller the filament diameter is, the easier it is to bend, to find out the relationship between the maximum bending strength and bending radius of various yarns, and to select from them.

From the aspects of weaving process and properties, it is necessary to improve the tongue needle head and guide pinhole of the special warp knitting machine, study the influence factors of fabric weave on glass fiber looping, change the warp flat weave into chain weave, and on the premise of meeting the requirement of looping, maximize the circle bending radius. Trial-produced glass fiber braided fabric, referred to as medical glass fiber warp knitted fabric.
