[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] An embodiment of the present invention discloses a pressure injury prevention device and monitoring system for critically ill patients.

[0033] Refer to Figures 1-5 , a pressure injury prevention device and monitoring system for critically ill patients, including a support base plate 1 and a control module. A support pad 8 is fixedly installed on the upper surface of the support base plate 1. A plurality of pressure adjusting devices 2 are evenly laid on the upper surface of the support pad 8. Support components 3 are fixedly provided around the support base plate 1 and are connected to a support frame 4 through the support components 3. A mattress main body 5 is detachably installed on the upper surface of the support frame 4 by bonding. A monitoring module is laid on the surface of the mattress main body 5;

[0034] The monitoring module includes a temperature sensor 6, a humidity sensor 7, and a pressure sensor 9. The temperature sensor 6 and the humidity sensor 7 are evenly fixedly arranged on the surface of the mattress main body 5. The pressure sensor 9 is fixedly installed on the surface of the pressure adjusting device 2 and is used to monitor the pressure change between each part of the patient's body and the mattress main body 5 in real time. The temperature sensor 6 and the humidity sensor 7 are used to monitor the temperature and humidity on the surface of the mattress main body 5;

[0035] The control module is used to receive the data transmitted by the monitoring module, analyze and process the data, and issue an alarm when abnormal pressure, temperature or humidity is found;

[0036] During specific use, the pressure sensor 9, temperature sensor 6 and humidity sensor 7 in the monitoring module can monitor the patient's physical condition and the pressure change of the mattress in real time; the pressure sensor 9 can accurately measure the pressure between each part of the patient's body and the mattress main body 5. When the pressure exceeds the preset threshold, the control module will notify the alarm module, and the alarm module will immediately issue an alarm to remind the medical staff of the remote control terminal to handle it; for example, if the pressure of a certain part is continuously too high, it may mean that the patient's body position needs to be adjusted or there is a problem with the pressure adjustment of the mattress. The medical staff can take timely measures to avoid the occurrence of pressure injuries;

[0037] The temperature sensor 6 and the humidity sensor 7 can monitor the temperature and humidity on the surface of the mattress main body 5 to prevent local overheating and dampness. For critically ill patients, the skin has weak resistance and is easily affected by temperature and humidity. If the temperature on the mattress surface is too high or the humidity is too large, it will increase the risk of skin damage, which may further lead to pressure injuries. This device can timely remind medical staff to take corresponding measures, such as adjusting the temperature and humidity in the ward, changing the patient's clothes and bed sheets, etc., by monitoring the temperature and humidity in real time and notifying the alarm module to issue an alarm in case of abnormalities, so as to keep the patient's skin in good condition and improve the nursing quality of critically ill patients.

[0038] The multiple pressure regulating devices 2 include mounting plates 21. An air pressure regulator 22 and an adjusting cylinder 25 are respectively and fixedly mounted on the upper surface of the mounting plate 21. The inner wall of the adjusting cylinder 25 is filled with an airbag. A support sliding column 26 is arranged on the upper side of the airbag. The support sliding column 26 is spliced and slid in the adjusting cylinder 25. A pressure sensor 9 is fixedly arranged on the top surface of the support sliding column 26;

[0039] The output end of the air pressure regulator 22 penetrates through the adjusting cylinder 25 through an air duct 23 and is communicated with the input end of the airbag in the adjusting cylinder 25. The output end of the airbag is communicated with an electromagnetic valve 24. The electromagnetic valve 24 is fixedly arranged on the inner wall of the adjusting cylinder 25;

[0040] The air pressure regulator 22 is used to inflate the airbag, and the electromagnetic valve 24 is used to control the deflation of the airbag; the local pressure of the mattress main body 5 is adjusted by inflating and deflating the airbag.

[0041] The control module controls the pressure regulating device 2 to automatically adjust the pressure of the airbag.

[0042] The control module is also connected to an external display module, which is convenient for real-time display of the pressure change of the mattress main body 5; medical staff can view the patient's physical condition and the pressure change of the mattress in real time through the display screen of the control module, which provides intuitive and accurate information for medical staff and is convenient for them to adjust the nursing plan in time.

[0043] There are multiple tiny pores on the surface of the mattress main body 5; the mattress main body 5 is made of a breathable elastic material, which has good air permeability and comfort; multiple tiny pores are distributed on the surface of this material, which can ensure air circulation and prevent local overheating and dampness.

[0044] The pressure sensor 9, the temperature sensor 6 and the humidity sensor 7 all use a wireless transmission method to transmit data to the control module.

[0045] The support assembly 3 includes a connecting column cylinder 31. The inner wall of the connecting column cylinder 31 is fixedly connected to the upright column 33 through a spring bracket 32, and the upright column 33 slides therein. The support assembly 3 cooperates with the support frame 4 to facilitate the disassembly and assembly of the mattress main body 5. Moreover, the structure of the support assembly 3 can bear the weight of the patient and various possible pressures and vibrations, ensuring that the device will not tilt or become unstable.

[0046] A monitoring system for a pressure injury prevention device for critically ill patients includes a remote monitoring terminal. The remote monitoring terminal is used to receive the data transmitted by the control module, analyze and process the data, and issue an alarm through the alarm module when an abnormal situation is detected.

[0047] The remote monitoring terminal further includes a mobile phone APP. Medical staff can view the patient's physical condition and the pressure change of the mattress main body 5 in real time through the mobile phone APP.

[0048] In the present invention, during use, the assembled pressure injury prevention device for critically ill patients is placed above the patient's bed to ensure the stability of the device. Then, assist the critically ill patient to lie on the mattress main body 5 to ensure that the patient's body is in full contact with the mattress main body 5. Adjust the patient's body position to make it in a comfortable state. When the patient lies on the mattress main body 5, the pressure sensor 9 in the monitoring module will monitor the pressure and pressure change between each part of the patient's body and the mattress in real time, and transmit the data to the control module. The control module analyzes and processes the pressure data, and calculates the optimal pressure distribution scheme according to the patient's weight and body position. If it is found that the pressure at a certain part exceeds the preset threshold, the control module will control the pressure regulating device 2 to automatically adjust the pressure of the corresponding airbag. For a patient with a heavier weight, the device will automatically increase the airbag pressure at the contact part between the mattress main body 5 and the body to better support the body and avoid excessive local pressure at the same time. For a patient with a lighter weight, the airbag pressure will be correspondingly reduced to provide a more comfortable support. When the patient lies on the side, the device can automatically increase the airbag pressure at the contact part between the side of the body and the mattress main body 5, and at the same time reduce the airbag pressure at the back and abdomen of the body to reduce the pressure concentration on the side of the body. Even if the patient remains motionless in the supine state for a long time, the device can continuously monitor the pressure change. If there is a slight change in the pressure at a certain part, it may be caused by a slight movement of the patient's body or a change in blood circulation. At this time, the corresponding pressure regulating device 2 will automatically adjust the airbag pressure according to the real-time monitored data to always maintain the optimal pressure distribution state.

[0049] The temperature sensor 6 and the humidity sensor 7 monitor the temperature and humidity on the surface of the mattress in real time and transmit the data to the control module; when abnormal temperature or humidity is detected, the control module will issue an alarm to remind the medical staff to handle it; the medical staff can take corresponding measures, such as adjusting the temperature and humidity of the ward, changing the patient's clothes and sheets, etc., to keep the patient's skin in good condition;

[0050] In addition, the medical staff can view the patient's physical condition and the pressure change of the mattress in real time through the display screen of the control module, so as to adjust the nursing plan in time; at the same time, the medical staff can also view the patient's physical condition and the pressure change of the mattress main body 5 in real time through the mobile phone APP, and can understand the patient's situation in time even when not in the ward; if any abnormal situation is found, the medical staff in the ward can be notified in time for handling.

[0051] It should be understood that the embodiments of the present application are not limited to the exact structures already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the embodiments of the present application is only limited by the appended claims.

[0052] The above embodiments only represent several implementation manners of the embodiments of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the embodiments of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the embodiments of the present application.
