Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of air mattress for medical use, and more specifically, an air bag set is arranged and combined. It can be achieved, and the point of contact with the human body is changed to provide sufficient ventilation, thereby preventing bed swelling of a patient who has been in a sick bed for a long time.

[0002]

[Prior art]

 The traditional structure of a medical air mattress that has an inflating and replacing function to alternate the point of contact with the patient to ventilate and prevent floor swelling is shown in FIGS. It consists of arranging a plurality of hollow air sacs 10 on a rigid board, connecting the air holes 11 of the air sacs 10 in even and odd rows therein to an air pump, and using a changeover switch to all air sacs. On the other hand, simultaneous evacuation or air inflow was performed, or air evacuation and air inflow were alternately performed evenly and oddly. However, in the case of the above-mentioned medical air mattress, in the event of a power failure or air pump failure, the gas in each air sac gradually leaks, causing a situation in which the patient comes into direct contact with the rigid board, causing discomfort to the patient. .

[0005] Therefore, there is a structure shown in FIG. 10 as an improved medical air mattress. This air mattress is formed by arranging and combining a plurality of air bladders 20 in the same manner as the one having the traditional inflated and inflated air bladder, wherein each of the air bladders 20 is connected to the upper air chamber 22 by one horizontal partition membrane 21. The lower chamber 23 is divided into lower chambers, and the gas in the lower chamber 23 is always kept in a saturated state. The compressed air exchange function was achieved, and the saturated gas inside the lower air chamber 23 prevented the patient from directly contacting the board in the event of a power failure or air pump failure.

[0004] The improved medical air mattress is divided into an upper air chamber 22 and a lower air chamber 23 by a horizontal partition membrane 21, only the upper air chamber 22 has an intake / exhaust function, and the elevation of the air sac is higher. The altitude of the air chamber 22 and, thus, can prevent the patient from feeling uncomfortable in the event of a power outage or mechanical failure, but the ventilation gap is limited to the height of the upper air chamber when performing alternate intake and exhaust. Therefore, the ventilation heat radiation effect was inferior to the above-mentioned traditional medical air mattress, resulting in floor congestion.

Further, when the gas inside each upper air chamber 22 is naturally discharged at the time of a power failure or mechanical failure, the upper surface of the air mattress becomes flat (see FIG. 11), and the patient comes into close contact with the air mattress surface. Inability to ventilated, resulting in bed pressure for the patient.

[0006] In addition, both the traditional medical air mattress having an inflating and replacing function and the improved medical air mattress described above, the exhaust air when entering and exhausting the adjacent air sac alternates when traveling. The air sac in the state has the common drawback that it does not sink down due to the pressure of the air sac on both sides of the air sac, and the ventilation gap becomes small, so that it is no longer possible to provide a good ventilation heat radiation effect.

[0007]

[Problems to be solved by the invention]

 An object of the present invention is to provide a medical air mattress having a kind of expansion / contraction replacement function. The medical air mattress can be used even if the air is gradually exhausted from the first air sac due to a power failure or a mechanical failure. (2) The support of the air sac prevents the patient from directly contacting the rigid board, and does not cause discomfort to the patient.

[0008] The present invention also provides a medical air mattress having the above-mentioned function of replacing and expanding and contracting, wherein the cross section of the second air sac is made circular or elliptical, and the air is gradually exhausted from the first air sac due to a power failure or a mechanical failure. Even if done, it is an object to reserve a small gap between adjacent second air sacs so as to be able to provide a ventilation effect.

[0009] The present invention further provides a medical air mattress having the above-mentioned inflating and replacing function, in which the second air sac can be filled with a liquid, whereby the second air sac has an appropriate weight. When alternately injecting / exhausting air from / into the row and odd-numbered airbag sets, the first airbag is pressed downward by the second airbag having an appropriate weight to increase the speed of air intake / exhaust, and to further reduce the ventilation heat. The task is to increase the gap to be provided and to provide a good ventilation heat radiation effect.
