[0002] In the field of medical care, pressure injury (also known as bedsore, pressure sore) is a long-existing and urgent problem to be solved. Pressure injury is mainly caused by a patient staying in the same position for a long time, with local tissues of the body being compressed for a long time, resulting in blood circulation disorders and tissue anoxia and necrosis, thus triggering skin damage.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1: As Figures 1 - 4 shown, a pressure injury monitoring and warning device that is convenient to fix includes a mounting mechanism 100, a first monitoring and supporting mechanism 200, a second monitoring and supporting mechanism 300, and a driving mechanism 400.

[0023] The installation mechanism 100 is used to connect with the bed body; the first monitoring and supporting mechanism 200 is installed on the installation mechanism 100, and the first monitoring and supporting mechanism 200 includes a plurality of first monitoring and supporting components 210; the second monitoring and supporting mechanism 300 is installed on the installation mechanism 100, and the second monitoring and supporting mechanism 300 includes a plurality of second monitoring and supporting components 310, and the plurality of second monitoring and supporting components 310 are arranged staggered with the plurality of first monitoring and supporting components 210; both the first monitoring and supporting mechanism 200 and the second monitoring and supporting mechanism 300 are used to detect the human body state.

[0024] The driving mechanism 400 is installed on the installation mechanism 100, and the driving mechanism 400 is used to drive the plurality of first monitoring and supporting components 210 and the plurality of second monitoring and supporting components 310 to move up and down alternately and reciprocally.

[0025] Specifically, the device is installed on the bed body through the installation mechanism 100. When in use, the user lies on the device, and the first monitoring and supporting mechanism 200 and the second monitoring and supporting mechanism 300 will detect the human body. When abnormal pressure, temperature or humidity is detected, the control system will activate the alarm, timely remind the nursing staff to take intervention measures, and turn off the alarm, effectively preventing the occurrence of pressure injuries.

[0026] When the alarm has sounded for a period of time and the nursing staff has not taken intervention measures, the driving mechanism 400 will operate, thereby driving the plurality of first monitoring and supporting components 210 and the plurality of second monitoring and supporting components 310 to move up and down alternately and reciprocally, and then supporting different positions of the user alternately through the plurality of first monitoring and supporting components 210 and the plurality of second monitoring and supporting components 310, thereby further preventing the occurrence of pressure injuries.

[0027] Such as Figure 2 and Figure 3 As shown, the installation mechanism 100 includes a fixing plate 101 and a plurality of fixing components 110. A first mounting frame 102 and a second mounting frame 103 are mounted on the top surface of the fixing plate 101, and a display controller 104 is mounted on the first mounting frame 102. A control system and an alarm are arranged in the display controller 104; The plurality of fixing components 110 are all mounted on the bottom surface of the fixing plate 101, and the plurality of fixing components 110 are used to connect the fixing plate 101 with the bed body.

[0028] Specifically, the fixing plate 101 serves as the support foundation of the device. The first mounting frame 102 and the second mounting frame 103 mounted thereon are used to fix the display controller 104 and the driving mechanism 400. The plurality of fixing components 110 can ensure that the device is stably connected to the bed body, prevent displacement or looseness during use, and enhance the stability and reliability of the device.

[0029] Such as Figure 3As shown, the fixing component 110 includes a fixing box 111, a wedge block 113, a first spring 114, and a handle 115. The fixing box 111 is installed on the bottom surface of the fixing plate 101, and an installation groove 112 is provided inside the fixing box 111; the wedge block 113 is slidably connected to the installation groove 112; the first spring 114 is located in the installation groove 112 and is fixedly connected to the wedge block 113; the handle 115 penetrates through one side of the fixing box 111 and is slidably connected to the fixing box 111, and one end of the handle 115 is fixedly connected to the wedge block 113.

[0030] Specifically, during installation, by placing the fixing plate 101 on the bed body, when placing it, the bed board of the bed body will contact the wedge block 113 and push the wedge block 113 to move inside the fixing box 111. When the wedge block 113 moves below the bed board, the resilience of the first spring 114 will push the wedge block 113 to move, so that the wedge block 113 protrudes from the fixing box 111, and the top of the wedge block 113 contacts the bottom surface of the bed board, making it impossible for the fixing plate 101 to separate from the bed body by itself. When it is necessary to separate the fixing plate 101 from the bed body, by pulling the handle 115, the wedge block 113 is driven to move inside the fixing box 111, so that the wedge block 113 separates from the bed board, and then the fixing plate 101 is moved upward to separate the fixing plate 101 from the bed body.

[0031] As Figures 4 - 8 shown, the first monitoring and supporting component 210 includes a first mattress 211, a bent pipe 213, a plurality of pressure sensors 215, a plurality of temperature sensors 216, a plurality of humidity sensors 217, two dampers 218, and two supporting springs 219.

[0032] A second mattress 212 is installed directly above the first mattress 211; the bent pipe 213 is installed between the first mattress 211 and the second mattress 212. A plurality of exhaust holes 214 are provided on the bent pipe 213, and a ventilation pipe 2131 is installed on the bent pipe 213, and a solenoid valve is installed on the ventilation pipe 2131; a plurality of pressure sensors 215 are all installed between the first mattress 211 and the second mattress 212; a plurality of temperature sensors 216 are all installed between the first mattress 211 and the second mattress 212, and the temperature sensor 216 is an infrared temperature sensor 216; a plurality of humidity sensors 217 are all installed between the first mattress 211 and the second mattress 212; two dampers 218 are both installed on the fixing plate 101, and the extending ends of the two dampers 218 are fixedly connected to the first mattress 211; the two ends of the supporting spring 219 are respectively fixedly connected to the fixing plate 101 and the first mattress 211.

[0033] Specifically, the second mattress 212 provides a comfortable lying surface for the patient. The design of the bent pipe 213 and the exhaust holes 214 helps to regulate the air circulation inside the mattress and reduce the sense of dampness. The pressure, temperature, and humidity sensors 217 monitor the environment between the patient and the mattress in real time. When abnormal pressure, temperature, or humidity is detected, the control system will activate the alarm to timely remind the nursing staff to take intervention measures and turn off the alarm, effectively preventing the occurrence of pressure injuries.

[0034] As Figure 5 shown, the first monitoring and supporting mechanism 200 further includes a first air tank 220, a plurality of first piston air delivery components 230, and a plurality of first filtering components 240.

[0035] The first air tank 220 is installed on the top surface of the fixed plate 101. The first air tank 220 is fixedly connected to a plurality of ventilation pipes 2131. The first air tank 220 is a high-pressure air tank. The plurality of first piston air delivery components 230 are used to deliver external air into the first air tank 220; the plurality of first filtering components 240 are used to filter the air entering the first piston air delivery components 230.

[0036] Specifically, when it is necessary to dehumidify the second mattress 212, when no one is lying on the device, the driving mechanism 400 drives the plurality of first piston air delivery components 230 to operate, so that the first piston air delivery components 230 deliver air into the first air tank 220. When the air pressure in the first air tank 220 reaches the preset value, the solenoid valve on the ventilation pipe 2131 will open, and the air in the first air tank 220 will enter the bent pipe 213 through the ventilation pipe 2131, and then the air will be discharged through the plurality of exhaust holes 214, thereby accelerating the air flow speed inside the second mattress 212 and facilitating the reduction of the humidity of the second mattress 212.

[0037] As Figure 7 shown, the first piston air delivery component 230 includes a piston device 231. The piston device 231 is installed on the first air tank 220 and has an air delivery pipe 232, an air extraction pipe 233, and a push plate 235. The other end of the air delivery pipe 232 is connected to the first air tank 220. Check valves are installed in both the air delivery pipe 232 and the air extraction pipe 233. The piston device 231 further includes a piston sheet and a piston rod; a second spring 234 is installed on the piston device 231, and the second spring 234 is used to automatically reset the push plate 235 of the piston device 231.

[0038] Specifically, when the push plate 235 is pushed in the direction close to the piston device 231, the push plate 235 will push the air inside the piston device 231 into the first air tank 220 through the piston rod and the piston sheet. When the push plate 235 moves in the direction away from the piston device 231, the external air will be sucked into the piston device 231 through the air extraction pipe 233. By reciprocally pushing the push plate 235, continuous and stable air delivery can be achieved.

[0039] As Figure 7 shown, the first filtering component 240 includes a filtering box 241, a filtering plate 242, and a cleaning brush 243. The filtering box 241 is installed on the top surface of the fixing plate 101 and is connected to the air extraction pipe 233; the filtering plate 242 is installed on the filtering box 241; the cleaning brush 243 is installed on the first mattress 211, and the cleaning brush 243 contacts the filtering plate 242.

[0040] Specifically, by providing the filtering box 241 and the filtering plate 242, the air entering the air extraction pipe 233 can be filtered to prevent air from entering the piston device 231 and the first air tank 220.

[0041] By providing the cleaning brush 243, when the first mattress 211 moves up and down, it will drive the cleaning brush 243 to move up and down. The moving cleaning brush 243 will clean the filtering plate 242, thereby preventing debris from blocking the filtering plate 242 and affecting the filtering efficiency.

[0042] As Figure 4 、 Figure 5 and Figure 9 shown, the second monitoring and supporting mechanism 300 further includes a second air tank 320, a plurality of second piston air delivery components 330, and a plurality of second filtering components 340. The second monitoring and supporting component 310 has the same structure as the first monitoring and supporting component 210; the second air tank 320 has the same structure as the first air tank 220, and the second filtering component 340 has the same structure as the first filtering component 240.

[0043] Specifically, the second monitoring and supporting mechanism 300 has the same structure as the first monitoring and supporting mechanism 200. By being arranged staggeredly with the first monitoring and supporting mechanism 200, the bed body can be monitored more comprehensively.

[0044] As Figure 10 shown, the driving mechanism 400 includes a first driving component 410 and a second driving component 420; the first driving component 410 includes a motor 411, a first shaft 412, a plurality of first cams 413, a first sprocket 414, and a chain 415. Among them, the motor 411 is a speed-regulating motor. A speed-regulating motor changes the speed of the motor by methods such as changing the number of pole pairs, voltage, current, frequency, etc. of the motor. A speed-regulating motor is an existing mature technology.

[0045] The motor 411 is installed on the first mounting bracket 102; the first shaft 412 is installed on the power output shaft of the motor 411, and the first shaft 412 is rotatably connected to the second mounting bracket 103; a plurality of first cams 413 are all installed on the first shaft 412, and a plurality of first cams 413 respectively contact the push plates 235 of a plurality of piston devices 231; the first sprocket 414 is fixedly sleeved on the first shaft 412; the chain 415 is connected to the first sprocket 414.

[0046] The second driving assembly 420 includes a second shaft 421, a plurality of second cams 422 and a second sprocket 423. The second shaft 421 is rotatably connected to the first mounting bracket 102 and the second mounting bracket 103; the plurality of second cams 422 are fixedly sleeved on the second shaft 421; the second sprocket 423 is fixedly sleeved on the second shaft 421, and the second sprocket 423 is connected to the chain 415.

[0047] Specifically, when the motor 411 operates, the motor 411 drives the first shaft 412 to rotate, thereby driving the plurality of first cams 413 to rotate. The plurality of rotating cams push the first mattress 211 upward. And when the first cam 413 rotates, it also pushes the push plate 235 of the piston 231 to extract and convey air.

[0048] Meanwhile, through the transmission of the first sprocket 414, the chain 415 and the second sprocket 423, the second shaft 421 and the second cams 422 drive the second piston air delivery assembly 330 in the second monitoring and supporting mechanism 300 to perform the same action. And the rotation of the second cam 422 also drives the second monitoring and supporting assembly 310 to move upward.

[0049] When the first monitoring and supporting assembly 210 moves upward, the first monitoring and supporting assembly 210 alone supports the user's body, so that the part of the user corresponding to the second monitoring and supporting assembly 310 is no longer oppressed.

[0050] When the second monitoring and supporting assembly 310 moves upward (at this time, the first monitoring and supporting assembly 210 moves downward), the second monitoring and supporting assembly 310 alone supports the user's body, so that the part of the user corresponding to the first monitoring and supporting assembly 210 is no longer oppressed; achieving the effect of local decompression and reducing the risk of pressure skin injury.

[0051] Working principle: In specific use, first fix the fixing plate 101 on the bed body through the mounting mechanism 100. The specific operation is as follows: Place the fixing plate 101 on the bed body. When placing it, the bed board of the bed body contacts the wedge block 113 and pushes the wedge block 113 into the fixed box 111. When the wedge block 113 moves under the bed board, the resilience of the first spring 114 pushes the wedge block 113 to move, so that the wedge block 113 protrudes from the fixed box 111, and the top of the wedge block 113 contacts the bottom surface of the bed board, making the fixing plate 101 unable to separate from the bed body by itself.

[0052] Then, the user lies on the first monitoring and supporting mechanism 200 and the second monitoring and supporting mechanism 300. At this time, the first monitoring and supporting assembly 210 and the second monitoring and supporting assembly 310 are in a level state.

[0053] Multiple sensors in the first monitoring support assembly 210 and the second monitoring support assembly 310 monitor pressure, temperature, and humidity. When abnormal pressure, temperature, or humidity is detected, the display controller 104 activates the alarm to timely remind the caregiver to take intervention measures and turn off the alarm, effectively preventing the occurrence of pressure injuries.

[0054] When the reason for triggering the alarm is that abnormal pressure is detected and the alarm has sounded for a period of time (which can be set by oneself) and the caregiver has not taken intervention measures, the display controller 104 will start the motor 411. The motor 411 will drive the first shaft 412 to rotate, and then drive multiple first cams 413 to rotate. The multiple rotating cams will push the multiple first monitoring support assemblies 210 to move upward, enabling the first monitoring support assemblies 210 to independently support the user's body, so that the corresponding part of the user in contact with the second monitoring support assembly 310 is no longer under pressure.

[0055] When the first shaft 412 rotates, it will also drive the second shaft 421 and multiple second cams 422 to rotate through the transmission of the first sprocket 414, chain 415, and second sprocket 423. The multiple rotating second cams 422 will drive the multiple second monitoring support assemblies 310 to move upward. When the second monitoring support assemblies 310 move upward (at this time, the tip of the first cam 413 does not separate from the first monitoring support assembly 210, and due to gravity, the first monitoring support assembly 210 will move downward), the second monitoring support assemblies 310 will independently support the user's body, so that the corresponding part of the user in contact with the first monitoring support assembly 210 is no longer under pressure, achieving the effect of local decompression and reducing the risk of pressure skin injury.

[0056] Among them, when it is necessary to dehumidify the second mattress 212, when no one is lying on the device, the drive mechanism 400 drives multiple first piston air delivery assemblies 230 to operate, so that the first piston air delivery assemblies 230 deliver air into the first air tank 220. When the air pressure in the first air tank 220 reaches the preset value, the solenoid valve on the air pipe 2131 will open, and the air in the first air tank 220 will enter the elbow pipe 213 through the air pipe 2131, and then the air will be discharged through multiple exhaust holes 214, thereby accelerating the air flow speed in the second mattress 212 and facilitating the reduction of the humidity of the second mattress 212.

[0057] Embodiment 2: Under the condition that other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is that the control system of the display controller 104 includes a threshold setting module, a data receiving and analyzing module, and a control module.

[0058] A threshold setting module, configured to receive the pressure duration threshold, temperature threshold, and humidity threshold set by the user, and receive the self-start duration threshold of the motor 411 set by the user.

[0059] A data reception and analysis module, configured to receive the data transmitted by the temperature sensor 216, humidity sensor 217, and pressure sensor 215, compare the received maximum temperature data with the temperature threshold, compare the received maximum humidity data with the humidity threshold, and compare the received pressure duration data with the longest duration with the pressure duration threshold; When the maximum temperature data reaches or is higher than the temperature threshold, the data reception and analysis module generates a first control signal and sends the first control signal to the control module; When the maximum humidity data reaches or is higher than the humidity threshold, the data reception and analysis module generates a second control signal and sends the second control signal to the control module; When the pressure duration data with the longest duration reaches or is higher than the pressure duration threshold, the data reception and analysis module generates a third control signal and sends the third control signal to the control module.

[0060] A control module, configured to receive the control signals transmitted by the data reception and analysis module, directly respond to the operations of the user, and control the start of the motor 411 or the opening of the solenoid valve according to the operations; When receiving the first control signal, the second control signal, and / or the third control signal, the control immediately starts the alarm; When the duration after receiving the third control signal exceeds the self-start duration threshold of the motor 411, and the user does not turn off the alarm (that is, the alarm triggered by the pressure duration data, and the continuous alarm duration exceeds the self-start duration threshold of the motor 411), the control starts the motor 411.

[0061] Embodiment 3: As Figures 1 - 10 shown, a working method of a pressure injury monitoring and warning device convenient for fixing includes the following steps: Step 1: Place the fixing plate 101 at the predetermined installation position on the bed. When moving the fixing plate 101 downward, the wedge block 113 will contact the bed, and the bed will push the wedge block 113 into the fixing box 111. When the wedge block 113 moves under the bed board, the resilience of the first spring 114 will push the wedge block 113 to move, so that the wedge block 113 protrudes from the fixing box 111, and the top of the wedge block 113 contacts the bottom surface of the bed board, making the fixing plate 101 unable to separate from the bed by itself; Step 2: When the user lies on this device, the pressure sensor 215, temperature sensor 216, and humidity sensor 217 continuously monitor the environmental data and transmit the data to the control system in the display controller 104 in real time for analysis and processing; Step 3: When the control system detects abnormal pressure, temperature, or humidity, it will activate the alarm to emit an alarm sound; Step 4: When the reason for triggering the alarm is due to detecting abnormal pressure and the alarm has sounded for a period of time but the caregiver has not taken any intervention measures, the display controller 104 will activate the driving mechanism 400 to make the motor 411 drive the first shaft 412 and the second shaft 421 to rotate. By means of the cam, the first monitoring support assembly 210 and the second monitoring support assembly 310 are pushed to move up and down alternately in a reciprocating manner, so that different parts of the user's body are supported in turn, achieving the effect of local decompression and reducing the risk of pressure injury; Step 5: When there is no one lying on this device, the driving mechanism 400 drives the first piston air delivery assembly 230 and the second piston air delivery assembly 330 to operate, delivering external air to the first air tank 220 and the second air tank 320. Then, by opening the solenoid valve, the air enters the elbow 213 through the ventilation pipe 2131 and is discharged through the exhaust hole 214, accelerating the air flow speed inside the mattress and achieving the dehumidification effect.
