Abstract

(57) [Summary] [Purpose] Cooling and drying air is blown out from the small air outlet of the air cell to cool and dry the affected area. [Structure] A large number of air cells 1 are arranged, cooled and dry air is sent into the air cells 1, and these air cells 1 are expanded and contracted alternately. A large number of air blowing holes 3 are provided in the air cell 1, and a part of the dry air sent into the air cell 1 is blown upward from the air blowing holes 3.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention uses a plurality of alternately inflated air cells to, for example, This relates to a supporting air bed.

0002

[Conventional technology]

In order to alleviate pressure sores in bedridden patients and skin irritation in burn patients, the By arranging a large number of air cells C that alternately inflate and deflate, the patient's weight can be adjusted to different levels. It is known that it is effective to use air bed B, which alternately supports the It is. This air bed B has a large number of air cells C and the supply and exhaust of these air cells C. It is comprised of an air supply and exhaust system (not shown) that performs this function. The air supply and exhaust system consists of many air cells. C is controlled so that it alternately expands and contracts as in states (a) and (b). The supporting position of the patient's body is changed by reversing the expanding air cell C, and the patient's body is This reduces the local burden on people.

[Problem that the idea aims to solve]

One of the factors that promotes the occurrence of bedsores, which are usually called bedsores, is fever, Sweat can cause the affected area to become hot and humid. Predicting the occurrence and acceleration of bedsores in patients For prevention and management, ventilate the area near the affected area and keep the affected area at a low temperature and low humidity to keep it dry. It is preferable to maintain it.

0004 The purpose of this invention is to blow out cooled and dry air from the air cell to prevent deterioration of the affected area. Our aim is to provide air beds for

[0005]

[Means to solve the problem]

The air bed according to the present invention to achieve the above object has a large number of air cells. Cooled and dry air is sent into the air cells in an array, and these air cells are exchanged. Equipped with an air supply mechanism that repeatedly expands and contracts each other, the air cells are provided with a large number of air cells. A small air blowing hole is provided, and a part of the air sent into the air cell is passed through the small air blowing hole. It is characterized by the fact that it blows out.

[0006]

[Effect]

The air bed having the above-mentioned configuration is operated by an air bed for expansion sent from an air supply mechanism A portion of the cooling and drying air is blown out through the holes in the air cell.

[0007]

【Example】

The present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 3. FIG. 1 is a perspective view of an air cell 1 used in an air bed according to the present invention. for example The air cells 1 made of vinyl chloride, etc. are The upper part of the air cell 1 has a large number of small air blowing holes 3, respectively. is provided. Note that the diameter of the small air blowing hole 3 is, for example, about 0.5 mm. There is.

[0008] FIG. 2 shows a cold air supply system, in which air pressurized by an electric blower 4 is supplied to a drying device 5, The air is sent into the air cell 1 via the cooling device 6, the switching device 7, and the supply and exhaust pipes 8a and 8b. Ru. A temperature control device 9 is attached to the cooling device 6, and the temperature of the cold air can be controlled at a constant level. It is now possible to The switching device 7 has two switches connected alternately to the supply and exhaust pipes 8a and 8b. Air is supplied and exhausted alternately to two groups of air cells 1, and a switching valve is used. Air supply and exhaust are carried out by the pump.

[0009] During use, the air supplied from the electric blower 4 is dried by the drying device 5. It is dried and cooled by a cooling device 6. This air is transferred to the supply and exhaust pipe 8 by the switching device 7. a, 8b to every other first group of air cells 1, and these air While inflating the cell 1, air is exhausted from the adjacent second group of air cells 1. issued and its state is maintained. This operation is performed every few minutes, and air cell 1 is They will expand and contract each other repeatedly. Also, the air blowing of the expanding air cell 1 Low-temperature, dry air is released from the outlet hole 3 toward the patient. and release This air cools and dries the affected area of the patient.

0010 Note that the air outlet holes 3 do not necessarily have to be provided equally in all air cells 1. Air cells 1 corresponding to areas of the body that are prone to perspiration, and the required number of air cells 1 It is preferable to provide them intensively at certain locations.

[0011]

[Effect of the idea]

As explained above, the air bed according to the present invention has small air blowing holes in the air cells. The patient's affected area is always kept dry by blowing out low-temperature dry air. can be maintained.
