Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of human body restraint, and in particular to a restraint device for the elderly based on clinical use in geriatrics. Background Art
[0002] With the arrival of old age, the body's tissue structure will gradually age, the functions of various organs will be impaired one after another, the overall body resistance will gradually decline, and the mobility and coordination functions will be significantly reduced. These physiological changes make the elderly very susceptible to various diseases. During the treatment of the elderly, they may undergo painful treatments such as intubation and chemotherapy. Because the elderly may not be conscious or the body is in too much pain, they sometimes touch the wound accidentally or intentionally, thus affecting medical operations. In this case, in order to ensure the smooth progress of the treatment process, medical staff may use restraints to limit the activities of the elderly to avoid additional actions from interfering with the treatment. For example, a restraint device for the elderly used in geriatric clinical practice disclosed in application number CN202210146714.8 restrains the elderly through a restraint device.
[0003] However, existing elderly restraint devices usually use rigid structures to restrain the elderly. The reason is that the rigid structure can provide a more stable fixing effect and reduce the possibility of the restraint device loosening during use. However, when used for a long time, the rigid restraint device will exert pressure on the skin and soft tissues of the elderly, which may cause skin damage, pressure sores (bedsores) and other problems.

Since the baffle 914 is elastically hinged, the baffle 914 can also reset automatically. In the initial state, the cooling end of the semiconductor refrigeration plate 912 is in the second storage box 911 and the first storage box 910. The working principle of the semiconductor refrigeration plate 912 is based on the Peltier effect. When a direct current passes through an electric couple composed of two different semiconductor materials, usually P-type and N-type semiconductors, one joint will absorb heat for cooling, while the other joint will release heat for heating.
[0026] Through the following specific structure, the positions of the wristband moving groove 3 and the footband moving groove 4 can be adjusted according to the wrists and ankles of the elderly. The bottom end of the bed board 1 is fixedly connected with the first fixed plate 10 and the second fixed plate 11. The bottom end of the bed board 1 is provided with a limiting groove 12. The outer wall of the first fixed plate 10 is fixedly connected with the first motor 13. The output end of the first motor 13 is fixedly connected with the first threaded rod 14, and the other end of the first threaded rod 14 is rotatably connected with the outer wall of the second fixed plate 11. The outer wall of the first threaded rod 14 is threadedly connected with the first transverse plate 15. The two ends of the first transverse plate 15 are respectively connected with the two storage shells under the wristband moving groove 3. 94 is fixedly connected, the top of the first horizontal plate 15 is fixedly connected with a first limit block 16 which is slidably connected to the limit groove 12, the outer wall of one of the supporting parts 2 is fixedly connected with a second motor 17, the conveying end of the second motor 17 is fixedly connected with a second threaded rod 18, and the second threaded rod 18 is rotatably connected to the outer wall of the second fixed plate 11, the outer wall of the second threaded rod 18 is threadedly connected with a second horizontal plate 19, the two ends of the second horizontal plate 19 are respectively fixedly connected with the outer walls of the two storage shells 94 under the foot ring moving groove 4, and the top of the second horizontal plate 19 is fixedly connected with a second limit block 20 which is slidably connected to the limit groove 12.
[0027] The working principle of the present invention is as follows: First, the elderly person lies on the bed board 1, and then the first motor 13 and the second motor 17 are started. The first motor 13 drives the first threaded rod 14 to rotate, and then the first limiting block 16 is limited by the limiting groove 12, so that the first horizontal plate 15 can drive the two storage shells 94 under the wristband moving groove 3 to move on the first threaded rod 14, and then the fixed frame 93 and the wristband 81 are moved by the storage shell 94 until they move to a wrist position suitable for the elderly, and the second motor 17 drives the second threaded rod 18 to rotate, and then the limiting groove 12 limits the second limiting block 20, so that the second horizontal plate 19 can drive the two storage shells 94 under the footband moving groove 4 to move on the second threaded rod 18, and then the fixed frame 93 and the footband 82 are moved by the storage shell 94 until they move to a ankle position suitable for the elderly, and then the medical staff stretches and expands the arc protection plate 835 in the wristband 81 and the footband 82 outward by hand, and then puts the wrist and ankle into the wristband 81 and the footband 82 respectively; When the wrist and ankle are respectively placed in the bracelet 81 and the anklet 82, the wrist and ankle squeeze the arc protection plate 835, so that the arc protection plate 835 drives the detection rod 832 to move outward, and then drives the conductive sheet 833 to slide radially on the resistance plate 834 toward the bracelet 81 and the anklet 82. Then the PLC controller detects the current of the sliding rheostat. When it is detected that the current passing through gradually increases, it means that the wrist and ankle of the elderly are thicker, which to a certain extent indicates that the elderly may have relatively greater strength. Therefore, the PLC controller controls the electric telescopic rod 923 to drive the anti-slip plate 924 to extend outward until the connecting plate 91 is squeezed, and the connecting plate 91 is squeezed by the anti-slip plate 924 to cause friction resistance to the connecting plate 91. Among them, the maximum cross-sectional diameter of the wrist and ankle of the elderly is proportional to the current passing through the sliding rheostat / the extension length of the electric telescopic rod 923 / the friction resistance caused to the connecting plate 91 / the pulling force required for the same distance between the wristband 81 and the anklet 82.
[0028] When the elderly person's wrist or ankle needs to move, the pulling force will gradually increase, and the electric telescopic rod 923, the anti-slip plate 924, and the moving block 922 will be pulled upward through the connecting plate 91, thereby squeezing the detection spring 925, and squeezing the pressure sensor through the detection spring 925. It should be noted that the pressure sensor only senses the existence of pressure. When the pressure sensor is squeezed, the electrical signal is transmitted to the PLC controller in real time through the pressure sensor. The reason is that there is already movement space for the wrist and ankle in the above-mentioned bracelet 81 and anklet 82. Therefore, after the pressure sensor senses the pressure, it means that the force used by the elderly is too large and needs to be stopped. Therefore, the semiconductor refrigeration plate 912 is powered on through the PLC controller, and the medical staff is paged at the same time, so that the medical staff can observe the real-time situation of the patient. The cold air emitted from the cooling end of the semiconductor refrigeration plate 912 is transmitted to the copper strip 915 through the heat conducting plate 916, and then transmitted to the connecting plate 91 through the copper strip 915. Since the connecting plate 91 is made of Nitinol material, the Nitinol alloy has high flexibility and ductility at low temperatures, and is easy to stretch and deform. Moreover, the connecting plate 91 (i.e., the Nitinol alloy thin plate) can be easily stretched by hand at room temperature or lower temperatures without the need for additional tools. Therefore, the cold air is transmitted to the connecting plate 91 through the copper strip 915, so that the connecting plate 91 can be easily stretched to a certain extent, which can prevent the rigid constraint from causing harm to the elderly, so that the hands and feet of the elderly can be partially moved without affecting the treatment. The pressure value received by the pressure sensor is proportional to the refrigeration efficiency of the semiconductor refrigeration plate 912; When the elderly person no longer applies force, the stepper motor is controlled by the PLC controller, and the stepper motor drives the rotating shaft 918 to rotate, thereby driving the semiconductor refrigeration plate 912 to rotate 90°, so that the heat dissipation end and the refrigeration end of the semiconductor refrigeration plate 912 exchange positions, and the heat is transferred to the copper bar 915 through the heat conduction plate 916 through the heat dissipation end, and the heat is transferred to the connecting plate 91 through the copper bar 915. When the temperature is higher than the transformation temperature of the connecting plate 91, the Nitinol alloy automatically returns to the preset shape due to its shape memory effect.
