Without more limitations. The element defined by the sentence "includes a..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0023] The burn turning bed with patient position monitoring function, such as Figures 1-3 As shown, it comprises a moving bed frame 1 and an upper bed plate 3 and a lower bed plate 4 detachably installed on the turning mechanism 2 at both ends of the moving bed frame 1, the moving bed frame 1 is provided with a guardrail 5 for installing and protecting the patient on the lower bed plate 4 on both long side sides, the inner side of the guardrail 5 is provided with a horizontal limit position monitoring device for monitoring the horizontal limit position of the patient, and the top of the guardrail 5 is provided with a height limit position monitoring device for monitoring the height limit position of the limbs at the bed edge of the patient; in the above structure, by providing the horizontal limit position monitoring device and the height limit position monitoring device on the guardrail 5 provided on the moving bed frame 1, the real-time monitoring of the limit position of the patient in the horizontal position and the height position of the limbs at the bed edge position is realized, the problem of affecting the treatment effect caused by the abnormal displacement of the patient position or the safety hidden trouble problem caused by the limbs crossing the guardrail is solved, the secondary injury caused by the patient falling out of bed is avoided, and the effect of alarming immediately once the monitoring finds danger is achieved.
[0024] As Figures 2-3As shown, the specific structure of the horizontal limit position monitoring device is as follows: The horizontal limit position monitoring device includes a side plate 9, an SB1 button switch 6, an SB2 button switch 7, and an alarm 8. The side plate 9 is elastically installed on the inner side of the guardrail 5, and the SB1 button switch 6 and the SB2 button switch 7 are respectively installed in the middle of the inner side of the two guardrails 5. The SB1 button switch 6 and the SB2 button switch 7 are connected in parallel in the power supply circuit, and the KT1 time relay 10 and the KT2 time relay 11 are connected in series with the SB1 button switch 6 and the SB2 button switch 7, respectively. The KT1 time relay 10... The KT1-1 delay switch and the KT2-1 delay switch of the KT2 time relay 11 are connected in parallel and then connected in series with the alarm 8. Specifically, both the KT1-1 delay switch and the KT2-1 delay switch are normally open delay switches with delayed closing. In the above structure, by elastically installing the side plate 9 inside the guardrail 5, when the patient's body or limbs move outward and squeeze the side plate, the side plate triggers the SB1 button switch 6 or the SB2 button switch 7, which is then activated by the alarm 8. This provides conditions for timely care when the patient's body position changes abnormally, ensuring that the patient's injury is in the correct treatment position and ensuring the treatment effect.
[0025] When a patient's limb or body compresses one side of the side plate 9, the side plate 9 moves outward, triggering the SB1 button switch 6 or the SB2 button switch 7. At this time, the coil of the KT1 time relay 10 or the KT2 time relay 11 is energized. When the activation time of the SB1 button switch 6 or the SB2 button switch 7 reaches the time requirement for the KT1-1 delay switch or the KT2-1 delay switch to close, the KT1-1 delay switch or the KT2-1 delay switch closes, and the alarm 8 is activated to remind medical staff to correct the patient's position in time to avoid secondary injury to the injured area.
[0026] like Figure 2 As shown, the elastic connection structure between the side plate 9 and the guardrail 5 is as follows: each of the four corners of the outer wall of the side plate 9 is fixed with a pin 12, and the pin 12 with a spring 13 is inserted into the stepped insertion hole at the corresponding position of the guardrail 5, and is fixedly connected with the guide block in the large diameter section of the stepped insertion hole to realize the elastic installation of the side plate 9 on the inside of the guardrail 5.
[0027] like Figures 2-3As shown in the figure, the specific structure of the height limit position monitoring device is as follows: the U-shaped rod 14 is arranged on the upper edge of the guardrail 5 with the notch downward, and the T-shaped groove is formed on the upper end surface of the two side walls of the guardrail 5, the large end of the U-shaped rod 14 is adapted to the T-shaped groove, and the screw part is adapted and connected with the nut through the through hole on the corresponding side wall of the U-shaped rod 14, the pressure sensor 15 is installed on the upper end surface of the guardrail 5, and the compression spring fixed on the top surface of the U-shaped groove of the U-shaped rod 14 is in contact with the pressure sensor 15, and the pressure of the patient's limbs acting on the U-shaped rod 14 is transmitted to the pressure sensor 15 under the guidance of the T-shaped bolt 16 and the T-shaped groove, and the pressure sensor 15 is connected in series with the alarm 2 17 and is connected in parallel in the power supply circuit; in the above structure, the pressure sensor 15 is arranged inside the U-shaped rod 14 and in contact with the compression spring on the top surface of the U-shaped groove of the U-shaped rod 14, which provides monitoring and alarm conditions when the patient's limbs are placed on the guardrail 5, so as to timely adjust the position of the patient and eliminate the risk of falling out of bed by climbing over the guardrail, thereby improving the safety and reliability;
[0028] When the patient's limbs are placed on the U-shaped rod 14, the pressure acting on the U-shaped rod 14 is fed back to the pressure sensor 15 through the compression spring, when the pressure reaches the set pressure value, the pressure sensor 15 is triggered, the alarm 2 17 is turned on, and the staff can timely correct the position of the patient's limbs, and a time relay can be connected in series on the branch of the pressure sensor 15, when the placing time meets the set time length, the delay off switch of the time relay is closed, and the alarm 2 17 is turned on after the alarm, which can avoid the disadvantage of alarm caused by short-time placing of the limbs.
[0029] As shown in the figure, Figure 1 The specific structure of the guardrail 5 is as follows: the guardrail 5 comprises a guardrail body 5-1 and a support column 5-2 integrally connected with the guardrail body 5-1 and extending downward at both ends of the guardrail body 5-1, the lower end of the support column 5-2 is fixed on the mobile bed frame 1 through a bolt, and the horizontal limit position monitoring device and the limb limit position detection device are arranged on the inner side and the upper edge of the guardrail body 5-1, respectively; specifically, the lower end of the vertical rod at both ends of the guardrail body 5-1 is inserted into the center hole of the corresponding support column 5-2, and the support column 5-2 and the vertical rod are fixedly connected as a whole through the hand wheel bolt 5-3 on the outer wall of the upper end of the support column 5-2.
[0030] The technical solution has the advantages of simple structure, novel design, low cost, immediate alarm effect when danger is detected by monitoring, and high use value for safe and effective nursing of burn patients.
