As stated, it is contemplated that at least one fluid pump 50 can comprise a plurality of fluid pumps.In one aspect, if a plurality of fluid pump is as shown in Figure 5 with the interconnection of the arrangement of parallel connection, then only a pressure relief valve 60 and a pressure transducer 120 need be placed in fluid pump and a plurality of air bag 30 and be communicated with hermetically.Yet; On the other hand, if a plurality of fluid pump is arranged in the air feed subsystem 52 discretely, shown in Fig. 6 and 7; Then each air feed subsystem separately can need at least one pressure relief valve and at least one pressure transducer, so that the independent interior air pressure of air feed subsystem of may command.
It is contemplated that each air feed subsystem 52 (if existence) can be to the group of balloons supply air of different bladder and/or a plurality of air bag 30.In an example, the first air feed subsystem can be supplied air to a plurality of air bags with each air bag far-end 32 upper shed 33, and the second air feed subsystem can be to a plurality of air bags supply air with each air bag near-end 31 upper shed.In second instance, the first air feed subsystem can be supplied air at a distance from an air bag to the every of a plurality of air bags 30, and the second air feed subsystem can be to remaining air bag supply air.In the 3rd instance; The first air feed subsystem 52 can be to every next but two air bag supply air of a plurality of air bags; And the second air feed subsystem can be to the air bag supply air of next every next but two of a plurality of air bags, and the 3rd air feed subsystem can be to the air bag supply air of all the other every next but twos of a plurality of air bags.Will recognize that as those skilled in the art this kind uses a plurality of subsystems can continue any amount of air feed subsystem to the way of 30 groups of supplies of a plurality of air bags air.
In one aspect, at least one fluid pump 50, at least one pressure relief valve 60 and at least one pressure transducer 120 can electrically be connected to computer 110.In addition, on the other hand, the impervious covering of at least one liquid can be placed on a plurality of air bags 30 and at least one installing plate 36.
In use; At least a portion of the air bag of patient support system 20 can be positioned on wheelchair surface 12 (not being integrated in the wheelchair surface of wheelchair if air bag is not other mode) of wheelchair 10; And if before do not connect, then a plurality of pipelines 70 of patient support system can be by connecting as described above.If wheelchair has a plurality of surface section 13, every section at least a portion that can have the air bag of the patient support system that is placed on it then.Alternatively, in one aspect, at least one foam pad 18 can be placed on below the patient support system 20.In one aspect, it is contemplated that the size of at least one foam pad or size are made and made the patient support system can be used for any traditional wheelchair.
Computer 110 can be connected to power supply, such as battery or reference power supply socket.In one aspect, user can use user input apparatus that the air pressure settings value that requires is input in the processor of computer.At least one pressure transducer 120 can be measured the air pressure in the air supply system and will represent the signal of the air pressure in the corresponding air bag to deliver to processor.This processor can be with making comparisons from the signal of at least one pressure transducer and the air pressure settings value of requirement.If the pressure that detects is higher than the air pressure settings value, then processor can be delivered at least one suitable pressure relief valve 60 with signal, causes this valve to be opened a period of time selectively, therefore, discharges air and the air pressure that reduces in the corresponding air bag.On the contrary, if the pressure that detects is lower than the air pressure settings value of requirement, then processor can be delivered at least one fluid pump 50 with actuated signal, causes this at least one fluid pump valve to open a period of time, thus, improves the air pressure in the air bag.Therefore, it is contemplated that at least one pressure transducer, computer, at least one pressure relief valve and at least one fluid pump can form a feedback circuit, this loop configuration one-tenth remains on the air pressure in the corresponding air bag under the air pressure that roughly requires.If there are a plurality of air feed subsystems 52; So also can imagine; Can form similar feedback circuit remains on the air pressure in the air bag separately of corresponding subsystem roughly under the air pressure that requires and (can individually set for each corresponding subsystem; Perhaps, can be set under the unified air pressure all corresponding subsystems).
In one aspect, other staff etc. can be applied to an external force on the patient support surface 34 formed wheelchair cushions that lost by the depletion of QI crushing on the wheelchair 10 in patient, doctor and/or the operating room, and the patient support surface that the depletion of QI crushing is lost is in the stress state.On the other hand, before patient support system 20 had been inflated to ideal air pressure settings value, the patient support surface 34 that the depletion of QI crushing is lost was under the stress state.On the other hand, before an external force was applied on the patient support surface that the depletion of QI crushing loses, the patient support system was just by the air pressure settings value that is inflated to requirement as described above.Aspect this, after the patient support surface that the depletion of QI crushing loses is in stress state, because external force can change the intrasystem air pressure of patient support.At least one pressure transducer 100 may detect this kind variation, but patient support system 20 therefore also self adjust as previously discussed, till reaching ideal air pressure settings value.
In one aspect, in case the patient support system that predetermined depletion of QI crushing loses reaches the air pressure settings value within predetermined franchise, then the air pressure in the patient support system 20 is just no longer adjusted.On the other hand, in case the patient support surface (and patient) that the depletion of QI crushing loses is issued to balance at stress state, then can close the patient support system that the depletion of QI crushing loses.Aspect this; After stress state is issued to balance; Patient then before moving wheelchair, no longer the air pressure patient support system 20 in adjusted (this system closes), so needn't carry computer everywhere and battery comes re-adjustment patient support system 20 in the process of use wheelchair.
In one aspect, computer 110 can continue to receive the input from least one pressure transducer 120, for example to be used for the purpose of monitoring.This information can be stored into computer-readable storage media, in order to taking out afterwards or on display or monitor, watching.Yet in this regard, in case reached the setting value that requires, computer just can not send signal at least one fluid pump 50 and/or at least one pressure relief valve 60.Because a plurality of air bags 30 are air bags that the depletion of QI crushing loses; So; In case within predetermined franchise, reached ideal air pressure settings value in the patient support system, and this moment, patient lay on the patient support surface 34 of depletion of QI crushing mistake, it is contemplated that so; Intrasystem air pressure is no longer required other variation, and this is because intrasystem air pressure will keep invariable.In this regard, therefore any additional load or the pressure that act on this moment in the system can not cause computer control circuit that system air pressure is made adjustment.
On the other hand, in case in predetermined franchise, reached the air pressure settings value of the patient support system of ideal depletion of QI crushing mistake, then computer 110 can automatically cut out.For example, in one aspect, if the air pressure of the patient support system of losing for the detected depletion of QI crushing of predetermined amount of time does not change, then computer can automatically cut out, so intrasystem air pressure is not just remake other adjustment.On the other hand, for example, said predetermined amount of time can be but be not limited to 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 15 minutes etc.Also having on the other hand, in case in predetermined franchise, reached the patient support system air pressure set points that ideal depletion of QI crushing loses, then user can manually be shut down computer, so will not do additional change for intrasystem air pressure.Also having on the other hand; In case in predetermined franchise, reached the air pressure settings value of the patient support system that ideal depletion of QI crushing loses, then at least one fluid pump and at least one pressure relief valve air bag that can lose with a plurality of depletion of QI crushings within the predetermined franchise of the patient support system air pressure that requires partly breaks away from.Because the patient support system is under the required pressure, patient can make computer be attached to the support pads that bed frame and low pressure loss or depletion of QI crushing lose in the wheelchair cushion that the depletion of QI crushing on moving wheelchair loses.
