Description

Inflatable air cushion bed

This creation relates to an inflatable air-cushion bed provided with an air cushion to provide heat dissipation airflow, in particular to an inflatable air-cushion bed with independent heat dissipation airbags to generate airflow.

For patients suffering from mobility problems due to sickness and need to stay in bed for a long time, in order to avoid skin lesions caused by long-term bed-riding, you must regularly ask someone to turn the bed to help the skin maintain blood circulation, which will cause the bed-ridden person Relatives have to bear considerable labor costs in care matters, so there is now an air-cushion bed that can control the contraction and relaxation of the airbag to change the pressure distribution on the body of the lying person.

However, in order to ensure the inflated shape of the internal airbag, this type of airbag bed often uses an air-impermeable material to make the airbag structure inside the airbed, so the heat dissipation capacity of the airbag itself is limited, although the lying person can pass through the airbag of the airbed Shrinking and relaxing to reduce the problem of long-term skin pressure, but also because of the air permeability of the mattress itself, the lying person often feels sultry and uncomfortable, and the serious person may even cause the lying person to suffer from other diseases such as eczema . Even if the lying person uses the air supply device such as an electric fan, the cotton covered by the lying person often blocks the ventilation of the part where the lying person is in contact with the air mattress bed surface, thereby causing obvious heat dissipation problems.

In response to this heat dissipation problem, there are currently multiple air holes on the top of the multiple airbags that form the air cushion bed side by side, so that the air in the airbag can be directly blown to the lying person from the multiple air holes, thereby taking away the moisture and temperature However, in actual use, the lying surface of the person lying on the bed may cover the air holes, thereby reducing the heat dissipation capacity of the air bed, so it is necessary to improve and innovate.

The main purpose of this creation is to provide an inflatable air cushion bed with independent heat dissipation airbags to generate airflow, so that the heat dissipation airbags will not be pressed by the patient, and the lack of obstruction of the airflow supply of the traditional air cushion bed is improved, thereby improving the heat dissipation of the air cushion bed Effectiveness.

The secondary purpose of this creation is that the structure of the heat dissipation airbag is simple, and there are partitions inside to avoid the adjacent adhesion between the inner wall surfaces, so that the heat dissipation airbag can rapidly expand and deform when receiving gas.

Another purpose of this creation is that the heat dissipation airflow generated by the heat dissipation airbag will be kept blowing along the shortest straight path to the support bed surface of the air cushion bed, so that the gas inside the air cushion bed can quickly convect to the support bed surface, so as to quickly bring Take the heat to achieve the effect of lying down comfortably.

In addition, the heat dissipation airbag is adjacent to the support airbag, and a contact area is formed. A peripheral fixed area and an unconnected free area are formed on the periphery of the contact area. The free area is located near the contact area An adjacent side of the supporting bed surface, and the fixing section is located on the other side of the contact area away from the supporting bed surface, so that a direction of deformation caused by the gas bladder being filled by the gas can face the supporting bed surface.

Furthermore, the fixing section is formed with a first connection part, a second connection part and a third connection part to be fixedly connected with the inflatable bladder, and the second connection part is located on the bottom side of the contact area, and the The first connecting portion and the third connecting portion are respectively adjacent to two opposite ends of the second connecting portion, so as to keep the traveling direction of the heat dissipation airflow substantially perpendicular to the supporting bed surface.

In another feasible embodiment, the supporting airbags are further provided with a plurality of auxiliary air holes, so that the air cushion bed has two sets of heat dissipation airflow sources at different height positions. The plurality of inflation tubes includes a first inflation tube, a second inflation tube, and a third inflation tube, the first inflation tube communicates with the support airbags arranged at odd positions, and the second inflation tube communicates with the arrangement The support airbags in even positions, and the third inflation tube communicates with the heat dissipation airbags.

The characteristic of this creation is that a plurality of heat dissipation airbags are independently arranged beside the plurality of support airbags forming the support bed surface, and the air holes on the heat dissipation airbag form a separation distance with the support bed surface, so that the heat dissipation airbags will not be affected by patients The pressure is maintained to keep the radiating air flow continuously blowing toward the supporting bed surface, thereby improving the heat dissipation effect of the air cushion bed.
