Description

Surgical surgical pillow

The present invention relates to a surgical pillow, and more particularly to a surgical pillow that can be conveniently used as a surgical aid in the surgical operation on the throat or chest.

Pillows used in conventional surgical procedures generally have a circular cross section or a rectangle or a square, and the pillowcase is a solid form of natural or synthetic resin instead of natural products such as rice straw, coarse rice, chaff, etc. in consideration of microbial contamination. Or a hollow micro cubic cube is used and the pillow cover is made of foamed polyvinylacetate (PVC) or foamed polyurethane (PU) to prevent contamination due to blood or body fluids and to provide easy cleaning and chemical resistance. Made of artificial leather material, no extra pillowcases are normally used.

However, the conventional surgical pillow is similar in shape to the conventional pillow except that it is made of a material that can minimize contamination by blood, body fluids, or microorganisms and is easy to clean. He did not have the function of supporting the head of the patient, but as a surgical aid to assist in the surgical operation.

On the other hand, in recent years, latex pillows, or so-called 'memory foam' pillows using polyurethane foams, are widely used as household bedding for a good night's sleep.

Here, the latex pillow is made of natural rubber, or synthetic rubber such as styrene butadiene rubber or isoprene rubber, and latex using natural rubber is highly elastic, natural material, human-friendly and expensive, and is made by low temperature emulsion polymerization. Latexes using styrene butadiene rubbers produced or latexes using isoprene rubbers produced by-products from petroleum extraction and purification processes are highly productive, inexpensive and suitable for mass production.

Therefore, latex pillows, which are manufactured as bedding for home use, are generally used in a form in which natural rubber and synthetic rubber are mixed at a predetermined ratio.

Recently, pillows made of low elastic polyurethane foam, a so-called 'memory foam', have been widely used. They lower the elasticity of the polyurethane foam to prevent pillow sickness and provide high comfort. It is known that there is an advantage in that it is excellent in morphology recovery and easy introduction of various antibacterial functional groups.
