Description

Technical Field

[0001] The present disclosure relates to the technical field of mattresses, and in particular to an anti-bedsore massage air mattress. Background Art

[0002] Bedridden patients lying on air mattresses lack mobility, resulting in prolonged pressure on the same area, which can easily lead to bedsores and secondary trauma. This can also require caregivers to regularly move the patient, increasing their burden. Current anti-bedsore air mattresses only massage the body, often overlooking the limbs. Therefore, limb massage requires a separate limb massage belt, which undoubtedly increases the difficulty and expense for the patient and their family. Furthermore, due to limited bed space, the excessive number of caregiving devices reduces the patient's mobility, hindering rest.

[0003] In addition, in existing air mattresses with massage straps, the air pipes of the massage straps are connected to the air strips of the air cushion, and the massage straps are inflated and deflated as the connected air strips are inflated and deflated; when the air cushion pressure is adjusted, the massage intensity is weakened; in addition, if there is a problem with the air circuit, the air circuit cannot be quickly checked.

DETAILED DESCRIPTION

[0035] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0036] According to one embodiment of the present disclosure, the utility model provides an anti-bedsore massage air mattress. Figure 1-6 As shown, an anti-bedsore massage air mattress comprises: an air pump 1 having a first exhaust nozzle 11 and a second exhaust nozzle 12 that work independently;

[0037] The air cushion body 2 is connected to the first exhaust nozzle 11, and the air cushion body 2 is configured to be able to inflate and deflate the air strip inside it through the first exhaust nozzle 11;

[0038] The massage bandage 3 has a plurality of independently arranged air bags 31 , which are connected to the second exhaust nozzle 12 ; the massage bandage 3 is configured to be able to inflate and deflate the plurality of air bags 31 therein through the second exhaust nozzle 12 .

[0039] The anti-bedsore massage air mattress provided by the present disclosure is provided with an air pump 1. The first exhaust nozzle 11 and the second exhaust nozzle 12 of the air pump 1 can each operate independently. Therefore, the air cushion body 2 connected to the first exhaust nozzle 11 can be independently inflated and deflated, and the massage strap 3 connected to the second exhaust nozzle 12 can also be independently inflated and deflated. Therefore, the anti-bedsore massage air mattress of the present application can simultaneously achieve the purpose of massaging the air cushion body 2 to prevent bedsores while also massaging the limbs to prevent limb muscle atrophy. The air cushion body 2 and the massage strap 3 of the present application are independent of each other, easy to use and store, and when a problem occurs on one side, it is also easy to troubleshoot the air path problem, and the operation is simple.

[0040] This application is used to care for bedridden patients who are seeking to prevent bedsores. The anti-bedsore massage air mattress incorporates a massage function based on an anti-bedsore air mattress. Equipped with massage straps, it not only prevents bedsores but also provides limb massage to prevent muscle atrophy in the limbs. In the event of a power outage, the air mattress maintains pressure and does not deflate.

[0041] In one embodiment, Figure 3-6 As shown, the air pump 1 includes:

[0042] The first pump core 13 has a first air supply port 131.

[0043] The first ventilation valve 14 has a first air inlet 141 and a plurality of first air outlets 142 , wherein the first air inlet 141 is connected to the first air supply port 131 , and the plurality of first air outlets 142 are connected to the first exhaust nozzle 11 correspondingly;

[0044] The first motor 15 is in transmission connection with the first ventilation valve 14;

[0045] The second pump core 16 has a second air supply port 161;

[0046] The second ventilation valve 17 has a second air inlet 171 and a plurality of second air outlets 172 , wherein the second air inlet 171 is connected to the second air supply port 161 , and the plurality of second air outlets 172 are connected to the second exhaust nozzle 12 correspondingly;

[0047] The second motor 18 is in transmission connection with the second ventilation valve 17 .

[0048] For example, the first motor 15 is a low-speed motor, the speed of the low-speed motor is 0.1~0.5rpm, for example, the speed of the low-speed motor is 0.1rpm; the second motor is 18 high-speed motor, the speed of the high-speed motor is 2~10rpm; for example, the speed of the high-speed motor is 4rpm.

[0049] For example, the first ventilation valve 14 and the second ventilation valve 17 may be made of plastic or ceramic.

[0050] The first ventilation valve 14 is in transmission connection with the first motor 15. Specifically, the first ventilation valve 14 comprises an upper valve and a lower valve, with multiple air passages formed between the upper and lower valves, connecting to the first air inlet and the first air outlet. The lower valve is stationary, while the upper valve is connected to the output of the first motor 15. The output of the first motor 15 synchronously drives the upper valve to rotate, thereby rapidly inflating and deflating the air passages within it. The first ventilation valve 14 also comprises a first vent, which communicates with the first air outlet and the outside world. This vent is used to deflate the air strips within the air cushion body.

[0051] Correspondingly, the second ventilation valve 17 is in transmission connection with the second motor 18. Specifically, the second ventilation valve 17 comprises an upper valve and a lower valve, with an airway formed between the upper and lower valves, connecting to the second air inlet and second air outlet. The lower valve is stationary, while the upper valve is connected to the output of the second motor 18. This output of the second motor 18 synchronously drives the upper valve to rotate, thereby rapidly filling and deflating the airway within the valve. A second deflation port is also formed within the second ventilation valve 17, connecting to the second air outlet and the outside world. This second deflation port is used to deflate the airbags within the massage band.

[0052] In one embodiment, Figure 5-6 As shown, the anti-bedsore massage air mattress of the present application also includes a circuit board 4, a first switch 5, a second switch 6, an adjusting knob 7 and a micro switch 8. The circuit board 4 is electrically connected to the first pump core 13, the first motor 15, the second pump core 16, the second motor 18, the first switch 5, the second switch 6, the adjusting knob 7 and the micro switch 8 respectively.

[0053] The circuit board 4 is used to receive the on / off signal of the first switch 5, thereby controlling the working status of the first pump core 13 and the first motor 15; the circuit board 4 is used to receive the on / off signal of the second switch 6, thereby controlling the opening or closing of the second pump core 16 and the second motor 18; the circuit board 4 is used to receive the adjustment signal of the adjustment knob 7 to adjust the working pressure of the first pump core 13.

[0054] Specifically, when the first switch 5 is in the on state, this state is in the fluctuating gear, that is, the first pump core 13 is in operation, supplying air to the first air inlet 141 of the first ventilation valve 14. At this time, the first motor 15 is in a low speed state, driving the upper air valve of the first ventilation valve 14 to rotate, so that the air passage in the first ventilation valve can rapidly inflate and deflate the air strip of the air cushion body 2 through the first exhaust nozzle 11, thereby realizing the alternating inflation and fluctuating mode of the air cushion body. When the first switch 5 is in the off state, this state is in the sleeping gear, the first pump core 13 is in operation, supplying air to the first air inlet 141 of the first ventilation valve 14. At this time, the first motor 15 is in a low speed state, driving the upper air valve of the first ventilation valve 14 to rotate. When it rotates to a certain position, it triggers the micro switch 8 to the normally open state, so that the air passage in the first ventilation valve 14 can simultaneously and rapidly inflate the air strip of the air cushion body 2 through the first exhaust nozzle 11. After reaching the pressure, the pressure is maintained, and the air cushion body 2 enters the sleeping state.

[0055] Among them, the micro switch 8 is electrically connected to the circuit board 4, and the circuit board 4 is used to control the opening or closing of the micro switch 8, that is, the circuit board 4 is used to control the opening or closing of the micro switch 8 according to the state of the first switch 5. Specifically, when the first switch 5 is in the closed state, which is the sleep gear, the micro switch 8 is turned on, and when the first motor 15 drives the upper valve of the first ventilation valve 14 to rotate to a certain position, the first ventilation valve 14 acts on the transmission element of the micro switch 8 (the roller on the micro switch), triggering the micro switch 8 to be normally open. The circuit board 4 receives the signal from the micro switch 8, controls the first motor 15 to close, the first ventilation valve 14 stops rotating, and the first pump core 13 keeps working, and the air bar of the air cushion body is quickly inflated at the same time, and the air cushion body enters the sleep state.

[0056] When the first switch is in the on state, the micro switch 8 is closed and the micro switch 8 is inoperative.

[0057] Circuit board 4 is used to receive on / off signals from second switch 6, thereby controlling the opening and closing of second pump core 16 and second motor 18. Specifically, when second switch 6 is on, second pump core 16 operates, supplying air to second air inlet 171 of second ventilation valve 17. At this time, second motor 18 operates at a high speed, driving the upper valve of second ventilation valve 17 to rotate. Multiple air passages within the upper valve rotate rapidly and sequentially inflate and deflate airbags 31 of massage strap 3 via second exhaust nozzle 12, thereby achieving an alternating massage function. When second switch 6 is off, second pump core 16 and second motor 18 cease operation.

[0058] For example, the first pump core 13 , the first ventilation valve 14 , the first motor 15 , the second pump core 16 , the second ventilation valve 17 , the second motor 18 and the circuit board 4 are installed in the pump housing 19 .

[0059] In one embodiment, Figure 1-2 As shown, the air cushion body 2 includes a plurality of first air strips 21 and second air strips 22 arranged at intervals. Adjacent first air strips 21 are connected to one of the first exhaust nozzles 11 through a first connecting pipe 23; adjacent second air strips 22 are connected to another one of the first exhaust nozzles 11 through a second connecting pipe 24.

[0060] In this embodiment, the first exhaust nozzle 11 is a dual exhaust nozzle, i.e., there are two nozzles in the first exhaust nozzle 11. Accordingly, two air channels, AB channels, are formed within the first ventilation valve 14. Consequently, there are also two first air outlets 142, each of which is connected to a first air outlet 142. Therefore, both AB channels within the first ventilation valve are connected to the first air inlet 141, and each AB channel is connected to the two nozzles in the first exhaust nozzle 11 via the first air outlet 142. Furthermore, one nozzle in the first exhaust nozzle 11 is connected to the first air strip 21 via the first connecting pipe 23, and the other nozzle in the first exhaust nozzle 11 is connected to the second air strip 22 via the second connecting pipe 24.

[0061] Therefore, when the first motor 15 drives the upper valve of the first ventilation valve 14 to rotate, the AB air passages therein are inflated and deflated sequentially, thereby inflating and deflated the first and second air bars 21 and 22. When the first switch 5 is in the on state, i.e., in the fluctuating gear, the first and second air bars 21 and 22 are inflated and deflated sequentially; when the first switch 5 is in the off state, i.e., in the sleep state, the first and second air bars 21 and 22 are inflated simultaneously until the air pressure in the air cushion body reaches the desired pressure, at which point the pressure is maintained.

[0062] For example, when there are three airbags 31, the second exhaust nozzle 12 is a triple exhaust nozzle, i.e., the second exhaust nozzle 12 has three nozzles. Accordingly, three air channels (CDE) are formed within the second ventilation valve 17, and the number of second air outlets 172 is also three, with each air channel connected to a second air outlet 172. Therefore, the CDE air channels within the second ventilation valve 17 are each connected to the second air inlet 171, and the CDE air channels are connected to the three corresponding air nozzles in the second exhaust nozzle 12 through the second air outlet 172. Furthermore, the three air nozzles in the second exhaust nozzle 12 are connected to the three airbags 31 of the massage band through the third connecting tube 25.

[0063] Therefore, when the second motor 18 drives the upper air valve of the second ventilation valve 17 to rotate, the three airways CDE are quickly inflated and deflated in sequence, for example, the C airway is inflated and the DE airway is deflated, or the D airway is inflated and the CE airway is deflated, or the E airway is inflated and the CD airway is deflated, so that the CDE airways are inflated and deflated in sequence, and then the three air bags are inflated and deflated in sequence through the second air outlet and the second exhaust nozzle to achieve alternating massage.

[0064] In one embodiment, when there is one massage bandage 3, the multiple air bags 31 of the massage bandage 3 are connected to the second exhaust nozzle 12 through the third connecting tube 25. When there is one massage bandage 3, it is only necessary to connect the air bags of the massage bandage 3 directly to the second exhaust nozzle 12 through the third connecting tube 25. Figure 1 、 Figure 3 As shown, the massage bandage 3 is provided with three air bags, and the second exhaust nozzle 12 has three air nozzles. The three air bags are connected to the three air nozzles in the second exhaust nozzle 12 through three third connecting tubes 25 respectively.

[0065] For example, Figure 2 、 Figure 3 As shown, when there are two or more massage bandages 3, the multiple airbags 31 of the massage bandage 3 are connected to the second exhaust nozzle 12 through the third connecting pipe 25 and the multi-way pipe joint 26. For example, if there are two massage bandages 3, one massage bandage has three airbags, and these airbags 31 are connected to the three air nozzles of the second exhaust nozzle 12 through the third connecting pipe 25 and the equal-diameter three-way pipe joint 26. Specifically, Figure 2 As shown, one of the second exhaust nozzles 12 is first connected to one of the three-way pipe joints via a connecting tube. The other two pipe joints of the three-way pipe joint are then connected to one of the airbags in the two massage bands via a third connecting tube 25. Similarly, the remaining exhaust nozzles are connected to the airbags in the massage bands via the third connecting tube and the three-way pipe joint. The massage bands are then attached to the legs or arms, allowing them to be alternately inflated and deflated to provide a leg or arm massage.
