Description

  The present invention relates to a nursing mat that is used while being laid on a bed.

In general, bedridden people such as elderly people who tend to be debilitated often do not turn over, and so-called pressure ulcers are brought into contact with the bed in the same posture. And floor slips are likely to occur.
Since pressure ulcers and bedsores are known to be caused by ischemia of human tissue or necrosis due to blood congestion, it has traditionally been possible to reduce the burden on the affected area to become ischemic. In addition, the nurse is careful to prevent the caregiver from having the same sleeping posture.
In recent years, care sheets for the purpose of reducing such pressure sores and bedsores and nursing have come to be used.
There are also nursing mats for similar use.
As this care mat, there is a mat formed by wrapping and housing an outer peripheral surface of a rectangular disc-shaped cushion body having a cushioning property with a cover (see, for example, Patent Document 1).

However, conventional care sheets and care mats have the effect of reducing the burden on the affected area and delaying the progress of pressure ulcers and bedsores, but have not been used for the purpose of improvement.
For this reason, once the body part is in a pressure ulcer or a bedsore, it is difficult to cure, and it has not been possible to reduce the burden of care such as the trouble of the caregiver.

  The present invention has been made in view of the above circumstances, and its main problem is that it can form a good environment for pressure sores and bedsores, and can reduce the burden of care The point is to provide a mat.

  The characteristic configuration of the care mat according to claim 1 of the present invention is that the upper surface layer is at least a mounting surface with respect to the cushioning layer having cushioning properties in a configuration having a size capable of mounting at least a part of the body. However, a cover made of a breathable material is covered, and an opening that communicates the outside with the inside of the cover is formed in the cover portion excluding the placement portion of the upper surface layer and the grounding portion of the lower surface layer.

  According to the above characteristic configuration, the presence of the cushion layer allows the body part to be flexibly received, and the presence of the opening allows the outside air and the inside of the covering to be always in a vented state. When the human body part is placed on the top surface of the mat, the cover part that is in direct contact with the human body part is kept in good contact with the body part by the breathable material, while the placing part of the human body part is It can be in a state where it is always placed under air circulation.

Accordingly, moisture stuffiness and the like can be reduced on the placement portion with the human body portion while suppressing the placement portion with the human body portion from becoming ischemic by the flexible cushion layer. Can prevent unnecessary moisture stuffiness on the placed part even when the placed human body part has pressure ulcers or bedsores, etc. It is possible to form an installation environment and to reduce the burden of care.

  According to a second aspect of the present invention, there is provided at least one pair of the openings along the periphery of the cushion layer.

  According to the above characteristic configuration, if there is at least a pair of openings, the air in the cover is not confined in the bag, so the air flow in the cover is smooth and moisture is not easily retained in the cushion layer. Can be formed.

  Therefore, the air permeability of the portion that contacts the human body portion can be kept good, so that the quality of use can be improved.

  According to a third aspect of the present invention, there is provided a nursing mat characterized in that the lower surface layer of the cover is formed of a waterproof member.

  According to the above characteristic configuration, the lower surface layer receives a body drainage fluid such as incontinence while ensuring sufficient air permeability of the placement portion with the human body portion, and the cover on which the human body portion is placed Since the part does not come into direct contact with the lower surface layer through the cushion layer, it is possible to reliably prevent contamination of the bed by accepting the drainage liquid due to incontinence while ensuring the breathability of the mounting part. it can.

  Therefore, it is possible to improve convenience, usability, and reliability as a care product.

  According to a fourth aspect of the present invention, there is provided a nursing mat having a characteristic configuration in which one end of the nursing mat in one direction and the other end of the nursing mat in the same configuration are detachable by connecting means. In each of the care mats, an opening is formed in the cover portion in the direction orthogonal to the connection direction.

  According to the above characteristic configuration, care mats having different sizes can be formed as necessary.

  Therefore, it can be used in an optimal size state according to the current situation, so it is easy to use.

  The characteristic configuration of the method for using the care mat according to claim 5 of the present invention is that the cushion layer is formed of a three-dimensional structure in which a space portion in the volume is formed to communicate in all directions.

  According to the above characteristic configuration, a highly breathable cushion layer can be formed.

  With such a configuration, for example, as shown in FIG. 3, the left and right openings 2 </ b> C and 2 </ b> C are placed on the bed B so that the left and right openings 2 </ b> C face the left and right sides of the bed B, as shown in FIG. A nursing mat A for mounting a body part such as the periphery is formed.

When the buttocks are placed on the nursing mat A, as shown in FIG. 4, the cushion layer 1 sinks moderately on the bed surface B1 side with the contact pressure being substantially uniform along the shape of the buttocks. Because it is too hard like hard cotton and does not sink, or like urethane, it does not sink so much that a desirable sleeping posture is obtained, making it difficult to create an ischemic state, and bed B With the openings 2C and 2C of the cover 2 opened to the left and right sides of the cover, when the heel portion does not move without being turned over, the air is in a ventilation state in which external air is taken into the cushion layer 1 due to the temperature difference, and turns over. When there is a slight movement in the buttocks, etc., the cover 2 acts like a basket and the cushion layer 1 is in a breathable state. In any state, the cushion layer 1 is breathable. Moisture around the groin that is secured and placed is removed through the upper surface layer 2A of the cover 2 made of a breathable material, and it is possible to suppress the propagation of germs and so on, so it is difficult to cause pressure ulcers and bedsores. An environment that can be done can be formed.

  Further, in such an environment, it is possible to suppress ischemia and propagation of germs in the affected area even in the current state of pressure sores and bedsores, and thus it is possible to suppress the progression of the affected area. .

  Furthermore, according to this nursing mat A, the upper surface layer 2A of the cover 2 is a breathable material and has good liquid permeability, and the heel portion is placed by the presence of the lower surface layer 2B of the cover 2 that is a waterproof material. Since the cover portion is not directly in contact with the lower surface layer 2B through the cushion layer 1, the discharged liquid such as incontinence permeates the bed surface B1 while ensuring the air permeability of the placement portion. Can be reliably prevented and can also be used as a care mat A for incontinence, so that it is possible to further reduce care care.

Further, the care mat A can be easily separated from the cushion layer 1 and the cover 2 by removal or can be easily assembled by attachment, and both can be cleaned. It has a structure that takes into account.
Here, the upper surface layer 2A of the cover 2 of this embodiment is formed of polyester, the lower surface layer 2B is formed of urethane, and both softening points exist on the higher temperature side than the boiling point of water. The mat A for nursing care which can be disinfected and is reliable in terms of hygiene can be formed.

  This care mat A is most breathable when used in a state where part or all of the openings 2C, 2C are exposed from the futon hung on the human body part, but it covers even if it is closed by the futon. Air permeability is formed by the repulsive action of 2 and thermal convection. Here, the wrinkle effect is caused by the caregiver turning over the caregiver or the helper turning himself / herself.

  Moreover, since the size of the air permeability can be formed by changing the size of the openings 2C and 2C of the care mat A, a plurality of types of openings whose sizes are changed may be formed. The size of the opening can be adjusted by opening and closing means such as hook-and-loop fasteners, fasteners and buttons so that the size of the opening can be freely changed, or a plurality of windows for opening and closing are provided. The size of the combined opening may be formed.

  In this care mat A, since there are openings 2C and 2C, the opening 2C and 2C are closed by a comforter or the like for the concern that it may be cold in the absence of heating in the severe winter season. Sex is the same as a normal mat. In addition, under such a state, even if the openings 2C and 2C are closed, they are not steamed.
