Description

Technical Field

[0002] When calculating the dosage of medication, the required energy, and evaluating the nutritional status and treatment effect of hospitalized patients, the weighing of body weight has important reference value. During hospitalization, the patient's body state may change dynamically. Medical staff need to measure the patient's weight regularly to calculate the dosage of medication, the daily energy required, and evaluate the nutritional status. However, the weight measuring scales commonly used in hospital wards are suitable for patients who can move freely and stand without the assistance of others. For patients who are seriously ill, have difficulty in moving, and are bedridden for a long time, it is difficult to obtain the patient's weight data using traditional weighing scales. Since patients need to calculate safe medication based on their weight, and dynamically grasp the patient's nutritional status and provide nutritional support in time, this brings many inconveniences to the diagnosis and treatment of diseases and nutritional management of medical workers and patients. At the same time, since most of the mattresses in hospitals are sponge mattresses, which are not very soft, the pressure on the skin of bedridden patients in contact with the surface of the mattress exceeds their own tolerance range, which is easy to cause pressure injuries for a long time.

The bottom end of the connecting spring 22 is fixedly connected with a bottom connecting thickened plate 23, and the bottom connecting thickened plate 23 is fixedly connected in the recessed groove 21. The top end of the connecting spring 22 is fixedly connected with a top connecting thickened plate 24, and the top connecting thickened plate 24 is fixedly connected to the bottom end of the transverse air cushion layer 3, improving the structural strength of the connection between the transverse air cushion layer 3 and the longitudinal air cushion layer 4 and the connecting spring 22, and the connecting spring 22 is made of a non-metallic elastic material to improve the use safety.

[0024] A plurality of longitudinal partition layers 5 are provided in the longitudinal air cushion layer 4, and the plurality of longitudinal partition layers 5 divide the longitudinal air cushion layer 4 into a plurality of longitudinal inflatable chambers 6. A plurality of transverse partition layers 7 are provided in the transverse air cushion layer 3, and the plurality of transverse partition layers 7 divide the transverse air cushion layer 3 into a plurality of transverse inflatable chambers 8. An air pump 1 is used for inflating the plurality of longitudinal inflatable chambers 6 and the plurality of transverse inflatable chambers 8, and the air pump 1 is equipped with an air cushion bed operator 9. The air pump 1 is connected to two external supply air pipes 17, both of the two external supply air pipes 17 are connected to a main supply air pipe 18, both of the two main supply air pipes 18 are connected to supply air branch pipes 19, and electromagnetic control valves 20 are installed on the plurality of supply air branch pipes 19. The plurality of electromagnetic control valves 20 are respectively located in the plurality of transverse inflatable chambers 8 and the plurality of longitudinal inflatable chambers 6 and are electrically connected to the air cushion bed operator 9. A pressure relief pipe system is provided in both the transverse air cushion layer 3 and the longitudinal air cushion layer 4. The pressure relief pipe system includes a through pipe 13, and the through pipe 13 is connected to an external extended pressure relief pipe head 14. The external extended pressure relief pipe head 14 is located outside the corresponding air cushion layer. A plurality of branch pipe heads 15 are connected to the through pipe 13, and electromagnetic on-off valves 16 are installed on the plurality of branch pipe heads 15. The plurality of electromagnetic on-off valves 16 are respectively located in the corresponding transverse inflatable chambers 8 and the corresponding longitudinal inflatable chambers 6 and are electrically connected to the air cushion bed operator 9. Through holes matching the through pipe 13 are provided on both the longitudinal partition layer 5 and the transverse partition layer 7, and a contact seal is provided between the through pipe 13 and the through holes. Through holes matching the main supply air pipe 18 are provided on both the longitudinal partition layer 5 and the transverse partition layer 7, and a contact seal is also provided between the main supply air pipe 18 and the through holes. Through the cooperation of the transverse air cushion layer 3 and the longitudinal air cushion layer 4, a support structure adapted to the lying patient is formed. Specifically, when in use, the air pump 1 is started and operated through the air cushion bed operator 9, and at the same time, a plurality of electromagnetic on-off valves 16 are controlled to be all closed, and a plurality of electromagnetic control valves 20 are controlled to be all opened. At this time, the air pump 1 works to supply compressed air into the two external supply air pipes 17. Since the external supply air pipes 17 are connected to the two main supply air pipes 18, and the main supply air pipes 18 are respectively connected to the supply air branch pipes 19 communicating with each transverse inflatable chamber 8 and longitudinal inflatable chamber 6, at this time, the corresponding transverse inflatable chamber 8 and longitudinal inflatable chamber can be inflated through the supply air branch pipes 19. After inflating to an appropriate state, the air pump 1 is turned off, and at the same time, the plurality of electromagnetic control valves 20 are closed. At this time, the gas volumes in the plurality of longitudinal inflatable chambers 6 and the plurality of transverse inflatable chambers 8 are kept constant. Thereafter, the lying patient can lie on the air cushion bed for use. When deflation is required, the electromagnetic on-off valves 16 are opened to discharge the gas in the longitudinal inflatable chambers 6 and the transverse inflatable chambers 8. If only the gas filling volumes in some of the longitudinal inflatable chambers 6 and the transverse inflatable chambers 8 need to be adjusted, the electromagnetic on-off valves 16 of the corresponding longitudinal inflatable chambers 6 and transverse inflatable chambers 8 can be adjusted accordingly. Through this design, by controlling the gas filling volumes in the longitudinal inflatable chambers 6 and the transverse inflatable chambers 8 during use, a height difference can be formed in the air cushion layer, which helps to assist the patient in adjusting different postures such as lying on the side.Meanwhile, it can also prevent a certain part of the skin of bedridden patients from constantly bearing pressure, effectively avoiding pressure injuries caused by long-term extrusion. During the treatment of patients with pressure injuries, the air cushion layer is adjusted to prevent the wound surface from being squeezed, so as to accelerate the wound healing speed, with stronger practicability and richer functionality. An air mattress switch, an indicator light, and a pneumatic pressure regulator are provided on the air mattress operator 9, and the air mattress operator 9 is electrically connected to the air pump 1, and can adjust the air mattress pressure according to needs. The inflation and deflation of the transverse air cushion layer 3 and the longitudinal air cushion layer 4 can be controlled through the air mattress operator 9, making it more convenient to use.

[0025] The pressure sensing layer includes a synchronous support plate 10 and a plurality of pressure sensors 11. The plurality of pressure sensors 11 are all installed between the planar support layer 2 and the synchronous support plate 10. The plurality of pressure sensors 11 are equipped with a weight measurement display 12. A weight measurement switch, a zeroing key, an indicator light, and a data display screen are provided on the weight measurement display 12. And a processing memory is provided in the weight measurement display 12. The weight measurement switch, the zeroing key, the indicator light, and the data display screen are all electrically connected to the processing memory, and can monitor the weight in real time, intuitively and dynamically. The longitudinal air cushion layer 4 is installed at the top of the synchronous support plate 10, and the air mattress operator 9 and the weight measurement display 12 are respectively installed at the left and right ends of the synchronous support plate 10. Through the cooperation of the planar support layer 2, the synchronous support plate 10, the pressure sensors 11, and the weight measurement display 12, an installation support structure adapted to the air cushion layer is formed, which is convenient for weighing the weight of bedridden patients while meeting the basic support use, and then convenient for monitoring the weight of bedridden patients, further enhancing the practicability. The surface material of the transverse air cushion layer 3 is a material with good air permeability and waterproof performance, providing better skin decompression, support and comfort, and is not prone to generate a stuffy feeling after long-term use. Binding straps 25 are provided on the planar support layer 2, which is convenient for the connection and positioning of the planar support layer 2 relative to the external hospital bed after laying. In this embodiment, the pressure sensors 11 are wireless pressure sensors, which is convenient for information conduction between the pressure sensors 11 and the weight measurement display 12 and is more convenient for installation.

[0026] In use, lay the flat support layer 2 flat on the patient's hospital bed. When necessary, form a lashing connection of the flat support layer 2 relative to the hospital bed through the lashing band 25. Since there is no gas in the longitudinal inflatable cavity 6 and the transverse inflatable cavity 8 initially, it is necessary to inflate the air cushion layer first. Operate the air pump 1 through the air cushion bed operator 9 to start the operation of the air pump 1. At the same time, control that all the electromagnetic on-off valves 16 are closed and all the electromagnetic control valves 20 are opened. In this state, when the air pump 1 works, compressed air can be supplied into the two external supply air pipes 17. Since the external supply air pipes 17 are connected to the two main supply air pipes 18, and the main connection pipes 18 are respectively connected to the supply air branch pipes 19 communicating with each transverse inflatable cavity 8 and longitudinal inflatable cavity 6, at this time, the corresponding transverse inflatable cavity 8 and longitudinal inflatable cavity can be inflated through the supply air branch pipes 19. After inflating to an appropriate state, cut off the power supply of the air pump 1 and close all the electromagnetic control valves 20 to keep the compressed gas volume in the multiple longitudinal inflatable cavities 6 and the multiple transverse inflatable cavities 8. Thereafter, the bedridden patient can lie on the air cushion bed for use. Since the multiple longitudinal inflatable cavities 6 and the multiple transverse inflatable cavities 8 are vertically distributed, the overall support form of the air cushion layer can be adjusted by controlling the gas retention in the corresponding longitudinal inflatable cavity 6 and transverse inflatable cavity 8. And by controlling the corresponding opening of the electromagnetic on-off valves 16, the control of the gas discharge in the corresponding longitudinal inflatable cavity 6 and transverse inflatable cavity 8 can be realized, which is used to enrich the adjustment methods of the longitudinal inflatable cavity 6 and the transverse inflatable cavity 8 and improve the richness of the overall support form of the air cushion layer. When the patient lies on the transverse air cushion layer 3, the detection data of the multiple pressure sensors 11 are read by operating the weight measurement display 12, and after the conversion of the detection values is formed through the processing memory in the weight measurement display 12, the weight of the patient is displayed on the data display screen. When the patient does not lie down, the weight measurement display 12 reads the detection data of the pressure sensors 11 and forms a record in the processing memory, so as to subtract the data in the state when the patient does not lie down from the data read when actually detecting the patient's weight to form an error compensation. When not in use and needing to be stored, first release the gas in the air cushion layer, and then untie the lashing connection of the lashing band 25 relative to the hospital bed, and then the mattress for monitoring the weight and decompressing the bedridden patient can be removed for storage.

[0027] The above are only the embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the present invention.
