Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] See Figures 1 to 3 As shown, a pressure ulcer protective pad with a sensing structure includes a protective pad body 1. The cross-section of the protective pad body includes a head pad 11, a shoulder pad 12, a chest pad 13, a waist pad 14, a foot pad 15, and a foot pad 16. In this embodiment, the cross-section of the protective pad body includes a first surface layer 17, a second surface layer 18, and a buffer layer 19 disposed between the first and second surface layers. The detection sensor and the inflatable airbag are located within the buffer layer. Both the first and second surface layers are medical-grade polyurethane layers. The buffer layer is a memory foam layer. The protective pad body is ergonomically designed and, according to the needs of patients of different body types, is approximately 200cm long and 100cm wide. It uses a medical-grade polyurethane layer, which has a smooth surface, reducing friction with the patient's skin and facilitating cleaning and disinfection, thus preventing cross-infection. The buffer layer, being a memory foam layer, has excellent cushioning and support properties, automatically deforming according to the patient's body contours to distribute pressure, alleviate pressure on key areas, and provide comfortable support.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the protective pad body has several detection sensors 2 and several inflatable airbags 3 fixed inside; the detection sensors include pressure sensors and blood flow monitoring sensors. The inflatable airbags are independently set and are made of highly elastic medical-grade silicone material. The surface pressure distribution of the protective body can be adjusted by inflating and deflating. In practical applications, the detection sensors and inflatable airbags can be placed in different positions according to the actual application. In this embodiment, the detection sensors and inflatable airbags are respectively placed at the face position of the head pad, the lung position of the chest pad, the shoulder joint position of the shoulder pad, the waist position of the waist pad, the knee joint position of the foot pad, and the ankle joint position of the foot pad. A controller 4 connected to the detection sensors and inflatable airbags is also provided on the outside of the protective pad body. The controller is used for automatic inflation and deflation control of the inflatable airbags and signal detection of the detection sensors.

[0030] The controller includes a housing, a power supply, a control circuit board, a display screen, an air pump, an inflation / deflation solenoid valve, operation buttons, and a wireless communication device. The detection sensor is connected to the detection signal input terminal of the control circuit board, and the display screen, operation buttons, and wireless communication device are also connected to the control circuit board. The control terminal of the inflation / deflation solenoid valve is connected to the control circuit board, and the air pump is connected to the inflatable airbag through the inflation / deflation solenoid valve. The power supply provides power to the control circuit board, display screen, inflation / deflation solenoid valve, and wireless communication device. The control circuit board has a conventional structure in existing technology, simply applied to receive, analyze, and process pressure and blood flow monitoring data. It adjusts the inflation / deflation of the corresponding airbag according to the pressure at different locations. The operation buttons allow for manual operation and mode switching, improving ease of use and effectiveness. The display screen facilitates viewing and management, while the wireless communication device enables remote control operation.

[0031] In this embodiment, the measurement range of the detection sensor is 0-100kPa, the accuracy is ±0.1kPa, and the response time is <1s.

[0032] A blood flow monitoring sensor can also be set: it can detect parameters such as blood flow velocity and blood flow rate, with a detection error of <5%.

[0033] Inflatable airbag: Maximum inflation pressure 20kPa, inflation time <30s, deflation time <60s.

[0034] Control system: Data processing speed ≥1000 times / second, wireless communication distance ≥30m.

[0035] Power supply: Built-in rechargeable lithium battery, which can work continuously for ≥12 hours after a full charge, or can be powered by an external power adapter.

[0036] How to use

[0037] Lay the protective pad flat on the hospital bed, ensuring that the surface of the protective pad is flat.

[0038] Connect the power supply, turn on the controller switch, and set parameters such as pressure threshold, blood flow threshold, and timed inflation / deflation interval using the operation buttons.

[0039] Assist the patient to assume a prone position and accurately place the patient's body on the protective pad body, ensuring that the critical parts fit well with the corresponding areas of the protective pad body.

[0040] Observe the pressure and blood flow data on the controller's display screen to confirm that the protective pad is functioning properly. During patient use, medical staff can periodically check the data and adjust parameters or take appropriate actions based on the patient's condition.

[0041] After use, turn off the control system switch, disconnect the power supply, and clean and disinfect the protective pad.

[0042] Clean the outer layer of the protective pad regularly with a mild medical disinfectant, avoiding the use of highly corrosive cleaning agents.

[0043] Check that the connections of the pressure sensor and blood flow monitoring sensor are secure; tighten them immediately if they are loose. Regularly check the inflatable bladder for damage or leaks; replace it immediately if any problems are found.

[0044] Conduct a comprehensive inspection of the control system monthly to ensure all components are functioning properly and data transmission is accurate. When not in use for extended periods, fold the protective pad and store it in a dry, well-ventilated environment, avoiding compression and moisture.

[0045] In this embodiment, the edge of the protective pad body is provided with a Velcro adhesive layer 5 for positioning when the protective pad body wraps around the human body. In use, the protective pad body can be laid flat, such as... Figure 3 As shown; a person lies on the protective mat, which does not need to be covered, and the person is lying supine, as... Figure 1 As shown, in order to measure effectively, it needs to be wrapped around the human body and positioned using Velcro adhesive layers to ensure the effectiveness of pressure monitoring at each location.

[0046] In this embodiment, the knee portion of the foot pad is arc-shaped, and the ankle portion of the foot pad is U-shaped.

[0047] Its working principle is as follows: Pressure and blood flow monitoring: When the patient uses a protective pad to assume a prone position for ventilation, the detection sensors at key locations begin to work, collecting pressure and blood flow data in real time and transmitting the data to the controller via wired or wireless means. The controller analyzes and processes the data, comparing it with preset normal pressure and blood flow thresholds.

[0048] Inflation and deflation control: If the pressure at a critical site exceeds a preset threshold and blood perfusion becomes abnormal, the controller determines that there is a risk of pressure ulcers at that site. It immediately issues a command to open the solenoid valve of the corresponding inflatable airbag, activating the inflation pump to inflate the airbag and cause localized bulging of the protective pad surface, dispersing pressure at that location. Once the pressure drops to the normal range and blood perfusion returns to normal, the controller stops the inflation pump and opens the solenoid valve to slowly deflate the airbag, returning it to its initial state. In addition, the protective pad is equipped with a timed inflation and deflation function. Every certain period (e.g., 1-2 hours), the control system automatically controls all inflatable airbags to complete an inflation and deflation cycle, further improving local blood circulation and preventing pressure ulcers.

[0049] This invention has the following positive effects: The structure of this invention is reasonably designed. It is equipped with an inflatable airbag, a detection sensor, and a controller, which can collect the pressure of various parts in real time, monitor the pressure status of key parts in real time, and control the air pressure in the inflatable airbag as needed, thereby relieving skin pressure in various parts and improving the effectiveness of pressure ulcer prevention. Furthermore, the controller improves the accuracy and timeliness of control of various parts. At the same time, the overall structure is comfortable to use, safe, convenient, reliable, and highly applicable.

[0050] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
