Description

Medical member (依 料 用 部 材)

The present invention relates to a medical member.

Conventional medical members were formed by cutting and sewing as garments free of natural and synthetic materials, and then attaching and closing openings such as buttons, strings, and fasteners to complete them.

Particularly, in water and vacuum garments, watertightness is extremely important, and nowadays, it is necessary to process a lot of effort and time to preserve this watertightness.

The present invention was developed in view of the above-mentioned matters, and by mixing a magnetic material with an elastic member and attaching the opening / closing portion or the connecting portion as a magnet, a special mechanism is not attached for opening and closing, and also it has watertightness. An object of the present invention is to provide a medical member capable of manufacturing clothes. Next, the present invention will be described.

As a material, a foaming agent, a crosslinking agent, and other auxiliaries are added to a rubber material (mixing both materials with a molecular weight of 200,000 and 2,000-12,000), and a magnetic substance is added to the magnetic material of fine particles in the form of fine particles. Mixed refining, left to mature, put into a mold and heated under pressure to form a foaming agent (foaming agent), and produced by cutting thinly to the required thickness (0.1mm-30mm), a woven fabric rich in elasticity on the thinly cut surface It is made by joining and cutting into the required shape, and making it a finished product, and preserving the magnetizing force required for the magnetic body of the part corresponding to the opening-closing part and connection part of this finished product.

In addition, the foam can produce closed and open bubbles in response to the demand, and in the case of closed bubbles only, the desired elasticity and shape integrity are maintained by mixing a relatively small diameter bubble with a large diameter bubble. You can get

Next, examples of the present invention are listed.

In addition, the magnetizer has a variable input power supply AC 1000-3500V, output voltage DC 200 / 220V 30A, electrostatic capacity 600UF, discharge circuit, thyristor (SCR), charging time 5 seconds, cycle 6 seconds, The yoke (landing plate) is contacted to the magnetizer by using a condenser (oil capacitor) to magnetize the NS pole at a speed of 1 second or less at random intervals, for example, 1 mm-20 mm, depending on the application. )

Since the present invention has the above-described configuration, it is possible to easily produce clothes with high watertightness and good elasticity, which are unthinkable with conventional clothes, and since the apparent specific gravity is only one, it is light and has good workability. In the industry, it can have a great effect as a work clothes in a factory producing high-precision parts or a garment used in water, and can be used as a variety of sandpapers as a medical auxiliary member. will be.
