In addition, each air bag in the bed tube of the embodiment is made of rubber, so that the air bag has good elasticity, and the vent hole can be made of plastic tubes.

The structure of the control valve of the present embodiment is as shown in fig. 4 to 7, and the control valve integrally includes a valve seat 301, an elastic membrane 3018, a switch assembly, and a control assembly, wherein specifically, the valve seat 301 is composed of a lower valve seat 3011 and an upper valve seat 3013 screwed to the top of the lower valve seat 3011, the lower valve seat 3011 and the upper valve seat 3013 are both circular structures, an air chamber 3012 arranged concavely is provided at the top of the lower valve seat 3011, an air inlet pipe 302, an air outlet pipe 307, and four air outlet pipes (a first air outlet pipe 303, a second air outlet pipe 304, a third air outlet pipe 305, and a fourth air outlet pipe 306) are further provided at the side of the lower valve seat 3011, and in addition, a pressure detection pipe 308 is provided at the side of the lower valve seat 3011.

In this embodiment, the lower valve seat 3011 may be formed by casting, and passages for communicating the air inlet pipe 302, the air outlet pipe 307, the air outlet pipes and the pressure detecting pipe 308 with the air chamber 3012 are formed in the lower valve seat 3011, so that an air inlet pipe communicating port 3021 for communicating with the air inlet pipe 302, an air outlet pipe communicating port 3071 for communicating with the air outlet pipe 307, a detecting pipe communicating port 3081 for communicating with the pressure detecting pipe 308, and a first air outlet pipe communicating port 3031, a second air outlet pipe communicating port 3041, a third air outlet pipe communicating port 3051 and a fourth air outlet pipe communicating port 3061 for communicating with the air outlet pipes are formed in the air chamber 3012, respectively.

The elastic membrane 3018 covers the top of the lower valve seat 3011, and the edge of the elastic membrane 3018 is lapped on the lower valve seat 3011 at the edge of the air chamber 3012, so that when the upper valve seat 3013 is connected to the lower valve seat 3011 in a threaded manner, the edge of the elastic membrane 3018 is pressed between the lower valve seat 3011 and the upper valve seat 3013, and the sealing of the elastic membrane 3018 to the top of the air chamber is realized through the pressing design. In this embodiment, the elastic membrane 3018 is designed to be thinner and made of a material with good toughness, so that the balls in the switch assembly to be closed can be reliably pressed down under the action of the control assembly, and the air flow space of the air chamber 3012 can be ensured by fully deforming the elastic membrane 3018 so as not to affect the air flow at other opened switch assemblies.

In this embodiment, the communication ports in the air chamber 3012 for connecting with the pipes are vertically arranged on the lower valve seat 3011 perpendicular to the bottom surface of the air chamber 3012, one switch assembly is respectively arranged at the communication ports of the air inlet pipe 302, the air outlet pipe 303 and the air outlet pipes, the control assemblies are corresponding to the switch assemblies, and are arranged in the upper valve seat 3013, and the switch assemblies and the control assemblies which are respectively arranged are separated by the elastic membrane 3018 on the upper side and the lower side.

The structure of the switch assembly in this embodiment is described taking the switch assembly at the first air outlet pipe communication port 3031 as an example, and the switch assembly specifically includes an elastic pad 3017 having a through hole in the center thereof disposed in the first air outlet pipe communication port 3031, a ball 3015 disposed on the elastic pad 3017, and a spring 3016 disposed through the through hole in the elastic pad 3017. Wherein the elastic pad 3017 is supported by a support cylinder 3010 at the bottom thereof, a through hole is also formed in the center of the support cylinder 3010, and the through hole near the top of the support cylinder 3010 is stepped, so that the bottom end of the spring 3016 is supported on the support cylinder 3010. In addition, a notch for communicating the inside and the outside of the bottom end of the support barrel 3010 is also provided at the side of the bottom end of the support barrel 3010, and a passage 3030 inside the lower valve seat 3011 for communicating with the first air outlet pipe 303 is communicated with the communication port through the notch and the through hole.

In this embodiment, in order to prevent the support barrel 3010 from being self-rotated in use, so that the notch is staggered from the channel 3030, and thus the channel 3030 and the through hole in the support barrel 3010 are plugged, a notch is further provided on the bottom end surface of the support barrel 3010, and simultaneously, an anti-rotation boss 3032 is also provided at the bottom of the first air outlet pipe communication port 3031, and after the support barrel 3010 is inserted into the communication port, the anti-rotation boss 3032 is embedded in the notch at the bottom of the support barrel 3010, so as to realize positioning of the support barrel 3010. In addition, in addition to providing the support cylinder 3010, the support cylinder 3010 may not be provided in the first outlet pipe communication port 3031 in this embodiment, and at this time, the top of the first outlet pipe communication port 3031 may be stepped to perform arrangement of the elastic pad 3017, and the spring 3016 may be designed to be longer at this time, so that the bottom end thereof is supported at the bottom of the first outlet pipe communication port 3031.

In the present embodiment, in a natural state, the spring 3016 is in a compressed state, and has an upward urging opening force applied to the balls 3015, as a result of which the balls 3015 are disengaged from the elastic pad 3017 and the portion of the elastic membrane 3018 located above the balls 3015 is lifted. At this time, the first air outlet pipe communication port 3031 and the air chamber 3012 are kept in a communication state, and the air entering the air chamber 3012 can enter the first air outlet pipe communication port 3031 and is finally discharged by the first air outlet pipe 303.

In this embodiment, the control assembly is still described by taking the first air outlet pipe communication port 3031 as an example, and the control assembly specifically includes a linear power output mechanism with a driving end disposed on the upper valve seat 3013, where the linear power output mechanism may be a push-pull electromagnet 309 disposed on the upper valve seat 3013, and the driving end of the linear power output mechanism is a pressure plate 3092 connected to an end portion of the push-pull rod 3091 of the electromagnet. Under the driving of the push-pull electromagnet 309, when the electromagnet push-pull rod 3091 drives the pressing plate 3092 to move downwards, the pressing plate 3092 is firstly abutted against the elastic membrane 3018, then the pressing plate 3092 continues to move downwards, so that downward pressing closing force can be applied to the ball 3015 by the elastic membrane 3018, and the ball 3015 is finally abutted against the elastic gasket 3017 by the pressing closing force, so that the first air outlet pipe communication port 3031 is closed.

In this embodiment, the elastic membrane 3018 and the elastic pad 3017 are made of rubber, the push-pull electromagnet is also made of the existing micro-electromagnet structure, and the switch assembly and the control assembly disposed at the other air outlet pipe, the air inlet pipe 302 and the air outlet pipe 307 are identical to the above structures, and are not described herein again. In the present embodiment, the pressure detecting tube 308 detects the pressure in the air chamber 3012 in real time, so that the switch component and the corresponding control component are not required to be disposed at the detecting tube communication port 3081, and it is also possible to dispose the switch component and the control component at the detecting tube communication port 3081.

In this embodiment, the gas in the gas inlet pipe 302 needs to enter the gas inlet pipe and the pressure detecting pipe 308 through the gas chamber 3012, and when the gas inlet pipe is used as the exhaust gas in the exhaust process, the gas in the gas inlet pipe also needs to enter the gas outlet pipe 307 and the pressure detecting pipe 308 through the gas chamber 3012. At this time, in order to reduce the influence of the arrangement of the elastic membrane 3018 on the gas flow in the gas chamber 3012, a protrusion is further provided at the center of the gas chamber 3012, which provides a certain support to the center of the elastic membrane 3018 to form a gap between the elastic membrane 3018 and the bottom of the gas chamber 3012.

In this embodiment, each push-pull electromagnet 309 is fixed in the upper valve seat 3013, in order to facilitate installation of each electromagnet, a cover plate 3014 is also disposed at the top of the upper valve seat 3013 in a screwed connection manner, and after each electromagnet is installed, a connecting wire of each electromagnet passes through a wire connection hole disposed at the side of the upper valve seat 3013.

When the control valve of the present embodiment is used, the connecting wires of the push-pull electromagnets 309 are connected to the controller, the air inlet pipe 302 is connected to the air supply mechanism, the air outlet pipe 307 is connected to the outside, the pressure detection pipe 308 is connected to the pressure sensor, the pressure sensor is electrically connected to the controller, and the air outlet pipes are connected to the ventilation 105 of the air bags on the bed pipe to be supplied. When the air bag connected with a certain air outlet pipe needs to be supplied, the push-pull electromagnet 309 at the position of the air inlet pipe communication port 3021 and the air outlet pipe communication port is controlled to move the pressing plate 3092 upwards and pull the pressing plate back, and at the moment, the spring 3016 jacks up the ball 3015, and the air inlet pipe communication port 3021 and the air outlet pipe communication port are communicated with the air chamber 3012. At the same time, the pressure plate 3092 at the communication port of the exhaust valve 306 and other air outlet pipes moves downward to press the ball 3015, closing the corresponding communication port. Thus, the air supply to the air bag connected with the set air outlet pipe can be realized.

When a certain supplied air bag is required to be exhausted, the communicating ports of the air inlet pipe 302 and other air inlet pipes are closed by the downward movement of the pressing plate 3092, and the communicating ports of the air outlet pipe connected with the exhaust air bag and the exhaust pipe 307 are opened by the jacking of the spring 3016, so that the air bag can be exhausted. In the air supply or exhaust, the air supply pressure or the exhaust pressure can be detected in real time by a pressure sensor on the pressure detecting pipe 308 for the controller to control according to the set threshold value.

The inflation mechanism of the present embodiment specifically adopts an air pump, and the whole structure of the air cushion bed with turning function, which is composed of a mattress, a control valve and an air pump, is shown in fig. 8, in which only one control valve 30 and a bed pipe body 10 are taken as an example, each air outlet pipe of the control valve 30 corresponds to each air bag in the bed pipe body 10, and other connected bed pipe bodies 10 and control valves 30 are connected in parallel with the air outlet of the air pump 20.

In use, the air cushion bed of the present embodiment is configured such that the air bags on the bed tube body 10 are communicated with the air outlet of the air pump 20 by the control valves 30, and the air supply and exhaust control modes of the control valves 30 are utilized as described above, so that the bed tube body 10 is inflated before the air bags are inflated during use, and then the bottom air bag 101 is kept inflated by the control valves 30 to serve as a support, while the left air bag 102 and the right air bag 103, which are respectively disposed on both sides, are inflated and deflated alternately as shown in fig. 9 and 10 under the control of the control valves 30, so that the body of the patient lying thereon can be turned over.

Further, in the present embodiment, the middle air bags 4 in the two adjacent bed tube bodies 10 can be alternately inflated and deflated as shown in fig. 11 by controlling the control valve 30 to realize cyclic decompression of the patient's body lying on the air cushion bed by alternately spacing each of the left air bag 102 and the right air bag 103. At this time, an alternate gap may be performed between one left airbag 102 and right airbag 103, so that only one of the adjacent two intermediate airbags 104 is deflated and inflated, then the next left airbag 102 and right airbag 103 are alternately spaced, and then the other intermediate airbag 104 is deflated and inflated. Of course, instead of the above, the left and

right airbags

102 and 103 may alternately be provided with a gap, so that the two adjacent middle airbags 104 may be inflated and deflated at one time.

In addition, in this embodiment, it should be noted that, in order to ensure the comfort of the patient's head during the use of the air cushion bed, the middle air bag 4 in the tube body 10 located under the patient's head may not be circulated for inflation and deflation, while the middle air bag 4 in the tube body 10 located under the other body part outside the patient's head may be alternately inflated and deflated.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should substitute or change the technical solution according to the technical concept of the present invention, to cover the scope of the present invention.
