DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortuary sheet such as a mortuary conveyance or laying sheet and a corpse face covering.

[0002]

2. Description of the Related Art Heretofore, as a mortuary body conveying sheet, a sheet obtained by laminating a non-woven fabric and sewing the sheet is known. This is provided with a non-woven fabric as a layer to absorb the moisture when the dry ice sublimates and liquid that comes out of the corpse to be laid, so that the corpse does not rot, and is laminated on the non-woven fabric so that the liquid does not leak out Processed and sewn to the sheet. However, because this sheet does not consider antibacterial, deodorant, and virus absorption, the body may rot, causing infectious diseases to hospital staff, funeral staff, and bereaved families.
There were also disadvantages such as giving off a bad smell. In addition, a sheet supporting a water absorbing agent that becomes a jelly when the nonwoven fabric absorbs water has been proposed. was there.

[0003]

SUMMARY OF THE INVENTION The present invention provides an antibacterial action,
An object of the present invention is to provide a mortuary sheet having a deodorizing action and a virus adsorbing action.

[0004]

A mortuary sheet according to the present invention is characterized in that a sheet containing a calcium phosphate compound is fixed on one side of a base cloth. Further, the present invention provides a mortuary sheet characterized by comprising a calcium phosphate compound-containing sheet, a base cloth, and a waterproof layer, the three layers being fixed, so that the outermost layer is a calcium phosphate compound-containing sheet. Is provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a mortuary sheet is used as a cloth used for carrying or laying a corpse on a stretcher or a futon or under a coffin and a cloth for covering the face of the corpse. Is what is done.

[0006] The base fabric used in the present invention is not particularly limited.
Various types can be used, for example, cotton cloth, silk cloth, synthetic fiber cloth, non-woven cloth, a sheet of a vinyl polymer such as polyvinyl chloride, and the like. Is also good.

Next, the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a mortuary sheet showing a first embodiment of the present invention. This mortuary sheet has a base cloth 1 and a calcium phosphate-based compound-containing sheet 2 overlapped and fixed. The fixation can be performed by suturing or gluing. As the calcium phosphate compound-containing sheet, a calcium phosphate compound having a Ca / P ratio of 1.0 to 2.0 having a particle size of 0.1 to 100 µm and a porosity of 10 to 2.0 in an organic polymer material matrix formed into a sheet shape. Those containing 75% of porous particles dispersed therein are preferred. Here, as the organic polymer substance matrix, paper (cellulose),
Nonwoven fabric, plastic foam (for example, urethane foam) and the like can be mentioned. The matrix used in the present invention must have voids containing particles of the calcium phosphate compound dispersed therein, but in the case of paper or nonwoven fabric, the voids may be spaces between the fibers, and in the case of plastic foam, the pores are continuous pores. It is necessary to be. The size of such fiber gaps and pores is not particularly limited, and can be appropriately selected according to the size and amount of particles to be dispersed. The thickness of the organic polymer substance matrix can be appropriately selected depending on the configuration of the body sheet and the purpose of use.

The calcium phosphate compound used in the present invention is not particularly limited as long as it has a Ca / P ratio of 1.0 to 2.0. For example, hydroxyapatite, calcium hydrogen phosphate, tricalcium phosphate , Tetracalcium phosphate and mixtures thereof. In the present invention, these calcium phosphate compounds are used as particles having a particle size of 0.1 to 100 μm. Particle size is 0.
When it is less than 1 μm, the particles are hardly aggregated and dispersed, and when it is more than 100 μm, it becomes difficult to adhere and support in the matrix. The appropriate particle size depends on the matrix used, for example, when paper is used as the matrix, 1
It is preferably from 30 to 30 μm. If the particle size is less than 1 μm, it will fall from the net of the paper machine together with water during papermaking, and if it exceeds 30 μm, it will be too heavy and difficult to disperse uniformly. Further, the particles of the calcium phosphate compound are preferably porous and have a porosity of 10 to 7
If it is less than 10%, sufficient surface area and water retention cannot be obtained, and if it exceeds 75%, strength sufficient for use as porous particles cannot be obtained.

In order to produce the calcium phosphate compound-containing sheet used in the present invention, when paper or nonwoven fabric is used as a matrix, a slurry of calcium phosphate compound particles is coated on paper or nonwoven fabric, Particles of the system compound can be added. When a plastic foam is used as a matrix, it can be produced by immersing the plastic foam in a slurry of calcium phosphate compound particles and drying.

FIG. 2 is a sectional view showing a mortuary sheet according to a second embodiment of the present invention. In this mortuary sheet, a waterproof layer 3 is provided on one surface of a base cloth 1, and a calcium phosphate-based compound-containing sheet 2 is overlaid and fixed thereon.
As the waterproof layer, a plastic film is preferably used, but a water-repellent layer coated with silicone may be used.
Examples of the plastic film include a polyolefin film such as a polyethylene film and a polypropylene film, a copolymer film of an olefin and vinyl acetate or acrylate, a polyester film such as a polyethylene terephthalate film, a polyvinyl chloride film, and a polyvinylidene chloride film. The plastic film can be laminated by a known extrusion coating method or the like. The thickness of the film to be laminated is not particularly limited, but is usually preferably 15 to 100 μm. If the thickness is less than 15 μm, sufficient waterproofness cannot be maintained, and if it exceeds 100 μm, it is difficult to fold and wrap the corpse (it is too thick and operability is poor).

FIG. 3 is a sectional view showing a mortuary sheet according to a third embodiment of the present invention. In this mortuary sheet, a waterproof layer 3 is provided on one side of a base cloth 1, and a calcium phosphate compound-containing sheet 2 is overlaid on the other side and fixed using a tape 4. The same plastic film and calcium phosphate-based compound-containing sheet as described above can also be used in this mortuary sheet. In addition, the aspect of the fixing portion, the fixing method, and the like are not limited to those shown in FIGS. 1 to 3 and can be appropriately selected.

Since the mortuary sheet of the present invention contains calcium phosphate compound particles, it absorbs bacteria, viruses, and malodorous components adhering to or leaching from the corpse. Further, the use of a waterproofed base fabric or the lamination of a plastic film can prevent liquid permeation.
