Description

  The present invention relates to an air mat suitable for preventing or preventing bedsores such as bedridden sick persons and elderly persons over a long period of time.

  Conventionally, as this type of air mat, for example, an air mat for preventing bed slip as shown in FIG. 7 exists. In this air mat, several rows of air chambers 22 and 22 for body support capable of being sealed in the length direction or the width direction are formed on at least the upper surface side of the mat main body 21 formed of a non-breathable sheet. Further, between the air chambers 22, 22, there are provided sub air chambers 24, 24 having a large number of pores 23, 23 on the upper surface side and having a bulging height smaller than the air chambers 22, 22. And it is comprised so that the air supply fan 26 can be connected to the air supply opening part 25 of the said sub air chambers 24 and 24 (patent document 1).

  In the conventional floor slip prevention air mat configured as described above, the clean air fed into the sub air chambers 24, 24 is a large number of pores 23 of the sub air chambers 24, 24 positioned between the air chambers 22, 22. , And effectively flows between the sleeping person's body and the mat to remove moisture between the body and the mat due to sweating. Therefore, the air around the body of the caregiver who has gone to bed is constantly exchanged without stagnation, and fresh and clean air is always in contact with the body of the caregiver, leaving room for bed slippage except for wet skin. In addition, it is said that dryness and treatment of the wound can be promoted to the affected part of the bedridden care recipient by the flow action of fresh air, and as a result, bedridden symptoms can be treated.

  Further, as this type of air mat, for example, an air mat for preventing bed slip as shown in FIG. 8 exists. This air mat takes a lot of sleeping weight such as shoulders, back, hips, buttocks, etc., and in the place where floor slippage is likely to occur, a plurality of flat polygonal air pads 31 are arranged vertically and horizontally, and below the thigh where occurrence of floor slippage is low A plurality of columnar bag-like air chambers 32 are arranged in parallel on the leg portion, and the arrangement pattern of the cells of the air mat with respect to the load weight is changed. The air pad 31 and the air chamber 32 are supplied with a pressurized gas heated to about the body temperature so that warm air is blown out from the pores 33, or the adjacent air pad 31 and the air chamber 32 are cut at intervals. It is assumed that the blowers 34 and 34 to which the divided strong and weak pressure gases are alternately supplied (Patent Document 2).

According to the conventional mat for preventing bed slipping constructed as described above, the arrangement pattern of the cells is devised, so that the bed slip preventing and treatment effects are greatly improved. In addition, there is little uncomfortable feeling about bedtime of the patient, and the adjacent air pads are alternately expanded, so it can be expected to have the same effect as turning over. The patient's body is always dry and hygienic. Furthermore, since warm air of about body temperature is ejected, normal body temperature is maintained without taking the body temperature from the patient's body, and the therapeutic effect is improved.

  However, conventional general bedsore-preventing air mats are contaminated with dirt and bad odors such as the body of a bedridden sick person or elderly person or bedding for a long period of time. For this reason, various germs or the like may propagate on the air mat itself or a bad odor may be generated.

  Further, the conventional air mat for preventing bedsores cannot remove the bad odor generated from a body such as a bedridden sick person or elderly person or bedding for a long time.

  The conventional mat for preventing bedsore shown in FIG. 7 can be said to have a deodorizing effect to some extent by removing moisture between the body and the mat, but it does not positively remove odor, However, it has a problem that it is not sufficient for the deodorizing effect. Further, since this air mat for preventing bedsore only removes moisture between the body and the mat, it cannot be said that it has a bactericidal effect, and it can prevent germs and the like from propagating on the air mat as described above. Can not.

  Further, the conventional air mat for preventing bedsore shown in FIG. 8 suppresses the generation of bacteria and radiates sweat etc., so there is little patient-specific odor, and the patient's body is always kept dry and hygienic. However, it cannot be said to be sufficient for antibacterial and bactericidal effects when various germs propagate on the air mat itself. In addition, there is a problem that it is not sufficient for the deodorizing effect when bad odors such as a bedridden sick person or an elderly person or bedding adhere to the air mat itself.

  Therefore, the present invention solves the above-mentioned conventional problems, can prevent bed slipping, of course, can remove the malodor itself that occurs from the body and bedding of bedridden sick and elderly people, etc. Moreover, even if dirt or bad odors such as bedridden sick or elderly people or bedding adheres to the air mat, it is possible to prevent germs and the like from breeding on the air mat itself or generating bad odors. It was made for the purpose of providing an air mat.

Therefore, in the present invention, the blowing means 2 is connected to the upstream side of the chlorine dioxide gas generating chamber 1 to which the chlorine dioxide gas generating bag 7 is detachably attached, and the air mat body 3 is connected to the downstream side of the chlorine dioxide gas generating chamber 1. An air mat that is connected and discharges chlorine dioxide gas generated from the chlorine dioxide gas generating bag 7 through a number of small holes H provided on the surface of the air mat body 3, and the chlorine dioxide gas generating bag 7. Is rounded along the peripheral wall 1a of the chlorine dioxide gas generating chamber 1, so that a circulation space 1b is formed at substantially the center of the chlorine dioxide gas generating chamber 1 .

  In the air mat according to the present invention, a check valve mechanism 4 is provided at a connection portion with the blowing means 2 on the upstream side of the chlorine dioxide gas generation chamber 1.

Furthermore, in this invention, the said chlorine dioxide gas generation bag 7 shall be divided into the 1st storage chamber 12 and the 2nd storage chamber 13, and the 1st storage chamber 12 accommodates a sodium chlorite solution, It is assumed that the saliva powder is stored in the storage chamber 13, and when a predetermined pressure is applied, the first storage chamber 12 and the second storage chamber 13 communicate with each other, and the sodium chlorite solution stored in the first storage chamber 12 The chlorine dioxide gas flows into the second storage chamber 13 and reacts with the white powder stored in the second storage chamber 13 to generate chlorine dioxide gas .

  Since the air mat of the present invention is configured as described above, it is possible not only to prevent bedsores, but also to remove malodors generated from the body and bedding of bedridden sick persons and elderly persons over a long period of time, Moreover, even if dirt or bad odors such as bedridden sick or elderly people or bedding adheres to the air mat, it is possible to prevent germs and the like from breeding on the air mat itself or generating bad odors. It became a thing.

  Embodiments of an air mat according to the present invention will be described below in detail with reference to the drawings.

  As shown in FIG. 1, the air mat according to the present invention has a blowing means 2 connected to the upstream side of the chlorine dioxide gas generating chamber 1 and an air mat body 3 connected to the downstream side of the chlorine dioxide gas generating chamber 1. Yes.

  The chlorine dioxide gas generating chamber 1 is formed in a substantially cylindrical shape or a substantially rectangular tube shape, and is provided with a check valve mechanism 4 at a connection portion with the upstream air blowing means 2, and an upstream air mat body. 3 is provided with an opening / closing lid 6 via a packing 5 at a connecting portion. The chlorine dioxide gas generating chamber 1 is detachably mounted with a chlorine dioxide gas generating bag 7. The chlorine dioxide gas generating chamber 1 and the air blowing means 2, and the chlorine dioxide gas generating chamber 1 and the air mat body 3 are connected through a hose 8 having an appropriate length.

  The blower unit 2 may be a blower pump as illustrated, but may be a blower fan. The blower means 2 prevents the chlorine dioxide gas generated in the chlorine dioxide gas generating chamber 1 from flowing back by the check valve mechanism 4 provided in the chlorine dioxide gas generating chamber 1, and rusts by the chlorine dioxide gas. The working condition is not deteriorated.

  The air mat body 3 is made of a non-breathable sheet material or the like, and has a hollow inside. The air mat body 3 is formed with a plurality of rows of gas flow passages 9 in the length direction of the air mat body 3. A gas communication passage 10 communicating with the air mat body 3 is formed around the air mat body 3. A large number of small holes H are provided on the surface of the air mat body 3 located above the gas flow passage 9. Further, the chlorine dioxide gas generation chamber 1 is connected to the gas communication passage 10 via a hose 8 so that the chlorine dioxide gas generated in the chlorine dioxide gas generation chamber 1 is distributed from the gas communication passage 10 to the gas flow passage 9. I have to. Therefore, the chlorine dioxide gas that has spread to the gas flow passage 9 is discharged from the small holes H provided on the surface of the air mat body 3 together with the air as will be described later.

  As shown in FIGS. 5 and 6, the chlorine dioxide gas generating bag 7 is configured such that the inside of the bag body 11 is partitioned into a first storage chamber 12 and a second storage chamber 13. The bag 11 is gas-liquid impermeable on the first storage chamber 12 side and gas-permeable and liquid-impermeable on the second storage chamber 13 side. Furthermore, the peripheral part 11a of this bag 11 and the partition part 11b of the 1st storage chamber 12 and the 2nd storage chamber 13 are closely_contact | adhered by heat seal etc., The difference in the contact | adhesion intensity | strength is given by the shape and state of a seal | sticker, etc. The adhesion strength of the peripheral edge portion 11a is made larger than the adhesion strength of the partition portion 11b. In order to generate chlorine dioxide gas, for example, the sodium chlorite solution is stored in the first storage chamber 12 of the bag 11, and the salash powder is stored in the second storage chamber 13.

  Therefore, when the chlorine dioxide gas generating bag 7 is applied with a predetermined pressure by hitting the bag body 11 with a palm or pressing it with a finger, the adhesion of the peripheral edge portion 11a of the bag body 11 is not released. Is not opened, but the close contact of the partition 11b is released, and the first storage chamber 12 and the second storage chamber 13 communicate with each other. Then, the sodium chlorite solution stored in the first storage chamber 12 flows into the second storage chamber 13 and reacts with the white powder stored in the second storage chamber 13 to generate chlorine dioxide gas. The chlorine dioxide gas generated in the bag body 11 is gradually released to the outside of the bag body 11 from the gas-permeable second storage chamber 13 side.

  The chlorine dioxide gas generating bag 7 is mounted in the chlorine dioxide gas generating chamber 1 so as to be rounded along the peripheral wall 1a of the chlorine dioxide gas generating chamber 1 so that a circulation space 1b is formed substantially at the center. Therefore, the air blown from the blowing means 2 passes through the circulation space 1b without resistance and is sent to the air mat body 3 together with the chlorine dioxide gas generated from the chlorine dioxide gas generating bag 7.

  In addition to the structure shown in the figure, the chlorine dioxide gas generating bag 7 is, for example, gas permeable and liquid impermeable so that the peripheral portion is not opened even when a predetermined pressure is applied. , Liquid impervious, and containing an inner bag body that opens at least a part of the peripheral edge when a predetermined pressure is applied. As long as the chlorine dioxide gas generated in the bag is gradually released to the outside of the bag, such as a sodium chlorite solution, the structure is not particularly limited. .

  In the air mat of the present invention configured as described above, when a sick person, an elderly person or the like operates the air blowing means 2 while lying on the air mat body 3, the air blown from the air blowing means 2 generates chlorine dioxide gas. Together with the chlorine dioxide gas generated from the chlorine dioxide gas generating bag 7 attached to the chamber 1, it is sent to the air mat body 3. Then, the air combined with the chlorine dioxide gas sent to the air mat body 3 reaches the gas flow passage 9 from the gas communication passage 10, and the air combined with the chlorine dioxide gas distributed to the gas flow passage 9 is Then, the air is released from a small hole H provided on the surface of the air mat body 3.

  At this time, the air combined with the chlorine dioxide gas is blown directly onto the body or bedding of a sick or elderly person sleeping on the air mat body 3, and this air promotes the ventilation effect and maintains the dry state. Sagging and bedsores of the sick and elderly are prevented. Furthermore, the deodorizing effect of chlorine dioxide gas is promoted by the air combined with the chlorine dioxide gas being directly blown onto the body or bedding of a sick or elderly person sleeping on the air mat body 3, Odor generated from the body of the sick or the elderly, bedding, etc. is effectively removed. Further, the air combined with the chlorine dioxide gas is bounced back to the body of the sick or the elderly, the bedding, etc., and blown to the air mat body 3, so that the sterilizing effect by the chlorine dioxide gas is promoted, and the air mat body 3 It is possible to effectively prevent germs and the like from breeding on the air mat, and even when a bad odor such as a bedridden sick person or an elderly person adheres to the air mat body 3, the bad odor attached to the air mat body 3 is also effective. Will be removed.

  If chlorine dioxide gas is no longer generated from the chlorine dioxide gas generating bag 7 attached to the chlorine dioxide gas generating chamber 1, the opening / closing lid 6 of the chlorine dioxide gas generating chamber 1 is operated to open and close a new chlorine dioxide gas generating bag. Needless to say, it should be replaced with 7.
