The other end is wound around the recovery wheel 44.

The air cushion 50 is internally provided with at least one air bag and an air passage connecting the air bag. In the embodiment, the air cushion 50 has a plurality of air bags 52 arranged at intervals, and an air passage 54 and each air bag 52. One side of the air passage 54 is connected to the gas so that gas can pass into each of the air bags 52. In practice, if the efficiency of the inflation is increased, a connected air passage may be provided on both sides of the airbag, instead of the single air passage design as the only embodiment.

As shown in FIG. 5, the inflator 60 is disposed under the bed. In the embodiment, the inflator 60 is located at a position of the bottom of the leg 20d adjacent to the recovery wheel 44. The inflator 60 Used to inflate the inflatable cushion 50.

FIG. 5 is a schematic view of the airbags 52 before being inflated (or after being degassed). The height of the airbags 52 is lower than the height of the rollers 30, and when the patient lies on the hospital bed. The patient is actually lying on the rollers 30, whereby the medical staff can first remove one or both of the front and rear bed heads, the bed ends 144, 146, and then in a more relaxed and less laborious manner. The patient is moved along the rolling direction of the rollers, and the patient is transferred to another bed, operating table or wheelchair.

Furthermore, since the height of the airbag 52 of the air cushion 50 after degassing is lower than the height of the roller 30, even if the patient is still lying on the hospital bed, it is actually lying on the rollers 30, and The inflatable cushion 50 of the hospital bed is not pressed by the patient. Thereby, the medical staff can directly perform the replacement operation of the inflatable cushion 50 without moving the patient or affecting the lying of the patient, thereby reducing the risk of accidents caused by moving the patient, thereby increasing the convenience of replacing the inflatable cushion. Sex and safety.

Referring to FIG. 6 , for the airbags 52 to be inflated, the airbags 52 are inflated and protrude from the rollers 30 from the gaps between the rollers 30 to make the airbags 52. The height is higher than the height of the rollers 30. Thereby, the inflated airbags 52 form an air mattress that can be used by the patient (eg, sitting, lying, etc.). In addition, it is worth mentioning that, through the arrangement of the plurality of airbags 52 arranged at intervals, the air mattress formed after the expansion forms a gap between each of the airbags 52, thereby contributing to the air circulation of the patient. Ventilation effect.

The embodiment of the inflator 60 of the above-described preferred embodiment will be described in detail with reference to FIG. 6 to FIG. 8. The inflator includes a base 62, a gas nozzle 64 and a gas pipe 66. The base 62 The air nozzle 64 has a gas mouth 64a at one end thereof, and the gas nozzle 64 is disposed on the through hole 62a of the base 62, and the gas mouth 64a is pierced from the hole 62a and facing away from the hole 62a. The recovery wheel 44 is connected to the air passage 54 of the air cushion 50. One end of the air tube 66 communicates with the other end of the air nozzle 64, and the other end is pumped with an air pump (not shown). Device connection. Thereby, when the air pump vents the air tube 66, the gas can sequentially pass through the air tube 66, the air nozzle 64 and the air nozzle 64a thereof into the air passage 54 of the air cushion 50, and then pass through the air passage 54 to the respective air passages 54. The airbag 52 is formed such that each of the airbags 52 is inflated to form the air mattress.

It is worth mentioning that, in order to further position the air nozzle 64 from the perforation 62a, a positioning member such as the bolt 200 may be locked on the base 62, and one end of the bolt 200 is offset. The gas nozzle 624 is positioned such that the gas nozzle 64 can be stably positioned in the base 64.

In addition, a portion of the bed 20 for the inflation cushion 50 to pass through may be provided with a clamping mechanism (not shown) for clamping the air passage 54 of the inflatable cushion 50 to block the gas. It is leaked from the air bag 52 and the air passage 54. The driving manner is that when the inflator 60 is to be inflated, the clamping mechanism can first loosen the clamping of the air passage 54 so that the inflating device 60 can smoothly inflate the airbags 54; When the air bag 52 of the air cushion 50 is fully charged, the clamping mechanism can be operated to clamp the air passage 54 of the air cushion 50 to prevent gas from escaping from the air passage 54. In this way, after the inflation is completed, the air bag 52 of the air cushion 50 can be effectively prevented from leaking. Wherein, the clamping mechanism may be a clip or a splint disposed on the upper and lower surfaces of the inflatable cushion for clamping the air passage of the inflatable cushion. In addition, in other embodiments, after the air cushion 50 is fully charged, the air passage of the air cushion can be sealed by hot melt, not limited to the embodiment of the clamping mechanism.

In addition, the clamping mechanism can also, but is not limited to, restricting a portion of the inflatable cushion that does not need to be inflated, that is, when inflating, the clamping mechanism can be used to first limit and distinguish the portion of the inflatable cushion to be inflated and not to be used. The inflated inflatable cushion portion is then inflated only for the inflated inflatable cushion portion, thereby achieving the effect of inflating the inflatable cushion portion according to the use requirements.

In addition, in addition to the clamping mechanism as a means of avoiding the air cushion to deflate, in practice, instead of using the clamping mechanism, a check valve (not shown) may be disposed between the air passage and the airbag, wherein The check valve allows only gas to enter the air bag 52 from the air passage 54. In this way, when the inflatable cushion is inflated, the corresponding airbag can be automatically closed by the design of the check valve, thereby achieving the effect of avoiding the leakage of gas in the inflatable cushion.

Instructions on how to operate the air mattress for changing the bed will be explained later. When the air mattress of the hospital bed is used for replacement work, the air mattress 52 can be deflated by the air mattress 52, and then the used air cushion can be wound up to the recovery wheel 44 through the power driving mechanism. At the same time, the output wheel 42 will continue to output a new, clean inflatable cushion 50, and penetrate into the accommodating space from the open portion on one side of the bed, and when the inflatable cushion 50 is worn When the bedboard is in the accommodating space, the inflatable cushion 50 is inflated through the inflator 40, and a new, clean air mattress can be formed again for the patient to use.

It is worth mentioning that the above method for deactivating the air mattress can be realized by a getter structure. Referring back to FIG. 7 and FIG. 8 , the getter structure may include a blade 80, and the blade 80 is disposed on the gas. The nozzle 64 is located at the rear of the nozzle opening 64a, and its blade is oriented in the same direction as the nozzle opening 64a. Thereby, when the inflatable cushion 50 is retracted to the recovery wheel 44 (the direction in which the inflatable cushion 50 is rolled is in the direction indicated by the arrow in FIG. 8), it can be cut by the blade of the blade 80, so that the The inflatable cushion 50 is broken and degassed.

In addition, the blade 80 may be disposed on the base 62 or below the bed plate near the recovery wheel 44, in addition to being disposed on the air nozzle 64. The advantage that the blade 80 is directly disposed on the air nozzle 44 is that when the air cushion 50 is to be recovered and retracted to the recovery wheel 24, it is ensured that the air cushion 50 can be effectively cut by the blade 80 to be deflated.

In addition, in other practical implementations, other structures having the effect of sharp, sharp or scratchable inflatable cushions may of course be adopted as the getter structure, for example, a gettering needle instead of the above-mentioned blade. limit.

In addition, in order to further improve the comfort of the patient using the air mattress, a non-woven layer (not shown) may be additionally attached to the surface of the inflatable cushion 50 as a buffer between the patient's body surface and the inflatable cushion 50. In other practical implementations, it is also possible to select a fabric layer having a cooling effect, a heat generating effect, or other therapeutic effects depending on the requirements of use, and not limited to the above non-woven layer.

Thereby, through the design of the hospital bed with the inflatable disposable mattress, the invention can quickly provide a clean disposable air mattress for the patient to use, and the design of the retracting and accommodating through the transmission device is convenient to operate. Save manpower and not take up space. In addition, it can avoid the risk of medical staff accidentally touching the mattress if they do not take protective measures. At the same time, the design of the disposable mattress can effectively avoid the risk of repeated infection of the mattress due to washing and disinfection. .

The above description is only a preferred embodiment of the present invention. The bed body is not limited to four bed plates, and may be composed of two, three or four or more bed plates. Depending on the requirements of the application, it is of course not necessary to use a multi-bed structure, but a design using only a single bed is not limited to the embodiment of the plurality of beds described above. In addition, the foregoing bed plate is not limited by the combination of the frame body and the plate body. In an embodiment, the bed plate may be only a single plate body, and the air cushion is directly laid on the plate body instead of It is limited to the above embodiment.

The wearing direction of the above-mentioned air cushion is not limited to the direction of the headboard 144 to the footboard 146. Of course, other designs may be adopted according to actual needs, for example, perpendicular to the head 144 board and the footboard 146. The direction of the connection is also one of the other feasible implementations.

In addition, in addition to the above-mentioned design of a set of transmission devices and an inflatable cushion in the bed body, in other applications, it is of course also possible to independently arrange a set of transmission devices and a corresponding inflatable cushion on each of the bed plates, thereby achieving individual Inflation, deflation, and individual replacement effects.

In addition, the above-mentioned bed plate is not limited to the structure in which the two boards are pivoted together. In an embodiment, the bed boards can also be independently controlled by a corresponding set of driving devices, and the respective bed plates can be individually driven relative to The angle of inclination of the horizontal plane is not limited to the above embodiment.
