Provided is a medical sheet characterized by being polyethylene. Further, the polyethylene-based resin is more preferably a short-chain branched low-density polyethylene obtained by copolymerizing ethylene having a density of 0.890 g / cm 3 or less and an α-olefin. The layer mainly composed of the polyethylene resin is preferably laminated on the sanitary paper by an extrusion lamination method. Further, the sanitary paper is preferably crepe paper or nonwoven fabric.

[0006]

[Embodiment of the invention]

 FIG. 1 is a partially enlarged sectional view showing the medical sheet of the present invention. The medical sheet 1 of the present invention comprises a sanitary paper layer 2 having water absorbency and a layer 3 mainly composed of a polyethylene resin having water repellency and waterproofness.

The sanitary paper layer 2 used in the present invention needs to have a function of absorbing and retaining chemicals, body fluids, sewage, and the like, and any sheet-like material having water absorbency can be used. For example, papers such as tissue paper and crepe paper, knitted or coarsely woven plain-woven fabrics, cellulosic materials such as cotton, rayon, and wood pulp, and nonwoven fabrics can be used. Crepe paper and nonwoven fabric of up to 40 g / m2 are preferably used.

[0008] The paper used in the present invention is a fourdrinier paper machine or a circular net paper machine obtained by mixing wood fibers and non-wood fibers, fillers and various chemicals mixed with water in a suitable beating machine. It is a sheet made by using a known paper machine such as an inclined paper machine and a twin wire paper machine. By creping the paper thus obtained, creped paper is obtained.

The nonwoven fabric used in the present invention is made from fibers such as wood fiber, cotton, rayon, polyethylene terephthalate, acrylic, acetate, nylon, and polypropylene, and is used for spunbonding, papermaking, carding machines and garnets. It is formed into a sheet by a known method such as a dry method using a machine.

[0010] The sanitary paper may be blended with a highly absorbent resin to absorb a large amount of water, or may be blended with a deodorant, activated carbon, silica gel, zeolite, etc. to maintain the deodorizing performance. . It is also possible to appropriately mix antibacterial agents and fragrances.

The layer 3 mainly composed of polyethylene resin used in the present invention needs to have a waterproof / water-repellent function. Furthermore, when used as a pillow cover or as a sheet for a consultation table, it is necessary to have anti-slip properties so that they do not slip or slip. Furthermore, it is necessary that curling does not occur when laminated with the sanitary paper.

For this purpose, the layer 3 mainly composed of polyethylene resin used in the present invention is mainly made of low-density polyethylene or polyethylene such as ethylene-ethyl acrylate copolymer or ethylene-vinyl acetate copolymer. A thermoplastic elastomer having a composition and a resin in which an anti-slip agent, a plasticizer, and the like are blended therein can be used. Among these, low-density polyethylene having a density of 0.925 g / cm3 or less is preferable, and short-chain branched low-density polyethylene having a density of 0.890 g / cm3 or less and obtained by copolymerizing ethylene and an α-olefin is particularly preferable. . By using these, the effects of anti-slip, curl prevention, flexibility and followability can be further exhibited. If the density of the low-density polyethylene exceeds 0.925 g / cm3, the slip resistance and the flexibility are poor.

These resins can be applied to the sanitary sheet in the form of an emulsion to obtain a medical sheet, but are preferably laminated on the sanitary paper by an extrusion lamination method. The amount of the layer 3 mainly composed of a polyethylene resin is preferably 10 to 30 g / m2.

In using the medical sheet obtained as described above, a medical solution or a body fluid generated during treatment or care is absorbed by the sanitary paper layer 2, and a portion that is difficult to get wet, such as an examination table or a pillow, The body of the caregiver or caregiver is brought into contact with the layer 3 mainly composed of polyethylene resin. The layer 3 mainly composed of a polyethylene resin blocks moisture absorbed by the sanitary paper layer 2 and prevents the moisture from adhering to the examination table, the pillow, the care giver, and the care giver.

On the other hand, if the sanitary paper has only water-repellent and water-repellent properties and does not have water absorbency, the medical solution or body fluid does not wet the examination table, pillows, therapists, and caregivers, but travels along the sheets to reach the floor. Troubles such as the following occur. However, the medical sheets obtained by the present invention do not have such troubles because the sanitary paper layer 2 has water absorbency.

The layer 3 containing polyethylene as a main component is excellent in anti-slip properties and flexibility, so that it can comfortably adhere to and follow pillows, clinics, caregivers, and the like.

The medical sheet obtained by the present invention is wound up in a roll as required, and the perforations are appropriately formed in the width direction to further improve the convenience. For example, as shown in FIG. 2, the use of a medical sheet with perforations installed on a consultation table can be further improved.

Further, the medical sheet obtained by the present invention can be suitably used as an apron by making a cut so that a human head can enter a part of the medical sheet.
