Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to an adjustable body position restraint device. Background Technology

[0002] Neurosurgery is a branch of surgery. It is a highly specialized and sophisticated discipline that, based on surgery as the primary treatment method, applies unique neurosurgical research methods to study the etiology and pathogenesis of diseases of the human nervous system, such as epilepsy, Parkinson's disease, and neuralgia, and to explore new diagnostic, treatment, and prevention technologies. When treating or caring for patients, to prevent sudden onset of symptoms that could lead to limb erratic movements, postural restraint devices are often used to restrain the patient's limbs.

[0003] Chinese Patent Announcement No. CN222075452U discloses a postural restraint device for neurosurgical nursing. The device includes a nursing bed with two sliding grooves in the middle of the top surface. An adjustment component is installed inside the sliding grooves, and the adjustment component is connected to a first mounting frame. A second mounting frame is fixedly connected to the top right side of the nursing bed. Fixing components are installed on the inner sides of the first and second mounting frames. A control panel is fixedly connected to the corner of the nursing bed. A water tank is fixedly connected to the middle of the bottom surface of the nursing bed. A heating pipe is fixedly connected to the inner wall of the water tank, and a water filling component is installed on the bottom surface of the water tank.

[0004] However, in the aforementioned patent, the first mounting frame can only be adjusted laterally. In actual neurosurgical nursing scenarios, patients have complex and diverse positioning needs. Adjustment in a single direction is far from meeting the need for comprehensive and precise adjustments to the positioning based on the patient's surgical site, physical condition, and rehabilitation stage. For example, for patients undergoing surgery in different areas of the brain, there are strict requirements for the placement angles of their head and limbs in multiple dimensions. The limitation of the adjustment of the first mounting frame in this patent makes it impossible to flexibly adapt to these complex positioning needs, thereby affecting the patient's rehabilitation effect.

[0005] Therefore, an adjustable body position restraint device is proposed to address the above problems. Utility Model Content

[0023] Example 1

[0024] Please see Figure 1-4An adjustable body position restraint device includes a nursing bed 1 and a moving block 15. A bowl support 17 is slidably connected to the upper part of the moving block 15, and the lower part of the moving block 15 is slidably connected to the nursing bed 1. A limit hole 16 is opened on one side of the moving block 15. An installation block 2 is fixedly connected to one side of the bowl support 17. A sliding rod 21 is slidably connected inside the installation block 2. One end of the sliding rod 21 is fixedly connected to a limit block 23. The limit block 23 is engaged inside the limit hole 16 and slidably connected inside the installation block 2. A spring 22 is sleeved on the outer wall of the sliding rod 21. The diameter of the limit block 23 is larger than the diameter of the sliding rod 21. The spring 22 is located inside the installation block 2. One end of the spring 22 is fixedly connected to one side of the limit block 23. A handle 24 is rotatably connected to the end of the sliding rod 21 outside the installation block 2. The handle 24 has a rounded corner on one side of the installation block 2.

[0025] In this embodiment, precise adjustment of patient positioning is crucial for rehabilitation in neurosurgical care. The sliding of the cup holder 17 to fit the patient's limb position is convenient and efficient for medical staff. The staff grasps the handle 24, whose anti-slip design assists in applying force, easily rotating the handle 24 90 degrees. During this process, the sliding rod 21 connected to the handle 24 rotates and translates synchronously. Because the limiting block 23 is fixed to one end of the sliding rod 21, it gradually and smoothly disengages from the limiting hole 16, and the cup holder 17 is freed from the locking constraint. Using the sliding structure above the moving block 15, medical staff can easily push the cup holder 17. Based on the patient's postoperative neurological function recovery stage or rehabilitation needs such as preventing muscle atrophy, medical staff can precisely control the limb placement angle and position, sliding the cup holder 17 to the desired position. Once in place, the staff rotates the handle 24 in the opposite direction, causing the sliding rod 21 to move the limiting block 23 towards the limiting hole 16. Spring 22 has excellent elastic recovery properties, which can quickly provide a strong restoring force to the limiting block 23, allowing the limiting block 23 to accurately and tightly engage with the limiting hole 16, thus achieving a stable and reliable positioning of the bowl support 17. In this way, regardless of the patient's unconscious movements or subsequent nursing operations by medical staff, the bowl support 17 can maintain its established position, continuously providing stable support for the patient's limbs and effectively promoting the postoperative rehabilitation process of neurosurgical patients.

[0026] Example 2

[0027] Please see Figure 1-4An adjustable body restraint device is provided, with hand straps 18 and leg straps 26 installed above the bowl support 17 and above the nursing bed 1, respectively. Velcro straps 19 are installed on the outside of both the hand straps 18 and the leg straps 26. A headrest 12 and a leg rest 25 are fixedly connected above the nursing bed 1. The leg rest 25 is located directly below the leg straps 26. Two threaded rods 13 are rotatably connected inside the nursing bed 1. The two threaded rods 13 are threadedly connected to two moving blocks 15, respectively. A knob 14 is fixedly connected to one end of each of the two threaded rods 13 outside the nursing bed 1. Support feet 11 are fixedly connected to the four corners of the bottom of the nursing bed 1.

[0028] In this solution, the hand straps 18 installed above the bowl support 17 and the leg straps 26 installed above the nursing bed 1 provide crucial protection for the patient's limb restraint. After neurosurgery, patients are relatively weak and may experience unconscious limb movements, which is extremely detrimental to wound healing and nerve recovery. The hand straps 18 and leg straps 26 are made of soft and elastic materials, which can restrain the patient's limbs while avoiding excessive pressure on the patient's skin, effectively preventing pressure sores. The Velcro 19 installed on the outside is ingeniously designed. When operating, medical staff can quickly adjust the tightness of the hand straps 18 and leg straps 26 by simply tearing or sticking the Velcro 19. When performing daily care for the patient, such as turning over or wiping the body, the Velcro 19 can be easily loosened and quickly re-secured after the care operation is completed, greatly improving the efficiency of the care work. In addition, the strong adhesion of the Velcro 19 ensures that the hand straps 18 and leg straps 26 can still maintain a stable restraint state when the patient struggles or moves unconsciously, providing the patient with safe and reliable limb fixation. The headrest 12, fixedly connected above the nursing bed 1, is carefully designed in shape and height. After neurosurgery, head support is crucial for patients. Inappropriate support can affect cerebral blood circulation and compress nerves in the head and neck. The headrest 12 adopts a shape that conforms to the curve of the human head, closely fitting the patient's head and evenly distributing the head weight, providing comfortable and stable support. This helps reduce head fatigue, promotes cerebral blood circulation, and has a positive effect on the recovery of postoperative neurological function. The leg support 25, located directly below the leg strap 26, also plays an important role. The leg support 25 can be flexibly adjusted in angle according to the patient's leg length and specific postoperative recovery needs. For neurosurgical patients, a suitable leg support angle can effectively prevent the formation of deep vein thrombosis in the lower extremities, while reducing pressure on leg muscles and preventing muscle atrophy. Medical staff can easily adjust the angle of the leg support 25 to adapt to individual differences among patients and provide personalized nursing services. The nursing bed 1 has two threaded rods 13 internally connected to two moving blocks 15. This design provides high precision in position adjustment. In neurosurgical nursing, precise fine-tuning of the patient's position is often required based on the patient's condition and rehabilitation plan. Medical staff can easily drive the threaded rods 13 to rotate by turning the knob 14 located at one end of the nursing bed 1. Due to the threaded connection between the threaded rods 13 and the moving blocks 15, the moving blocks 15 will move smoothly on the nursing bed 1 as the threaded rods 13 rotate. The knob 14 has clear scale markings on its surface, allowing medical staff to intuitively understand the movement distance of the moving blocks 15, thereby achieving precise control of the position of the bowl support 17 and meeting the high precision requirements of neurosurgery for patient position adjustment.

[0029] Working principle: Check whether the support legs 11 of the nursing bed 1 are stable, ensure that the nursing bed 1 is placed stably in a suitable position, avoid shaking or displacement during subsequent use, and provide a safe and stable foundation for the patient; Check the position and status of the headrest 12 and leg support 25. Based on the patient's height, body type and other factors, initially adjust the headrest 12 to a suitable height so that it can support the patient's head well. Ensure that the leg support 25 is located directly below the leg strap 26 and is in an adjustable state so that the leg support angle can be adjusted later according to the patient's needs. Transfer the patient smoothly to nursing bed 1, and let the patient's head rest comfortably on head pillow 12. Adjust the patient's body position on nursing bed 1 appropriately according to the patient's postoperative recovery to ensure that the patient is in a relatively comfortable initial position. Place the patient's hands on the bowl support 17 and the legs on the corresponding positions on the nursing bed 1, and prepare to use the hand straps 18 and leg straps 26 to restrain the limbs. Pick up the hand strap 18 and wrap it around the patient's wrist. Adjust the tightness of the hand strap 18 using the Velcro 19 to ensure that it can firmly restrain the patient's hand and prevent unconscious movements without putting excessive pressure on the patient's wrist. In the same way, use the leg strap 26 to restrain the patient's legs. Wrap the leg strap 26 around the patient's calf and adjust the tightness using the Velcro 19 to ensure that the patient's legs are comfortable and that their movement is restricted within a safe range. If it is necessary to adjust the position of the bowl support 17 and the patient's upper limbs according to the patient's condition and rehabilitation needs, the medical staff can hold the handle 24. Since the handle 24 has a rounded corner on one side that fits against the mounting block 2, it is comfortable and safe to operate. Turn the handle 24 to drive the sliding rod 21 to rotate and move within the mounting block 2. As the sliding rod 21 moves, it overcomes the elastic force of the spring 22, causing the limiting block 23 fixed at one end to gradually disengage from the limiting hole 16. At this time, the bowl support 17 is no longer restricted by the engagement between the limiting block 23 and the limiting hole 16, and medical staff can easily push the bowl support 17 to slide above the moving block 15. After sliding the bowl support 17 to a position that allows the patient's upper limb to be in a suitable position, rotate the handle 24 in the opposite direction. The spring 22, with its own elastic restoring force, pushes the limiting block 23 to re-engage into the limiting hole 16, thus fixing the position of the bowl support 17 and providing precise support for the patient's upper limb. If further adjustments to the patient's overall position are needed, medical staff can turn the knob 14 on the outside of the nursing bed 1. The knob 14 has a built-in high-precision gear transmission device, which makes the rotation smooth and effortless. Rotating the knob 14 causes the threaded rod 13 to rotate smoothly inside the nursing bed 1. Since the threaded rod 13 is threadedly connected to the moving block 15, the moving block 15 will move smoothly along the track on the nursing bed 1 as the threaded rod 13 rotates. During the movement of the movable block 15, it drives the bowl support 17, which is fixed in position above, and the patient's upper limbs to move synchronously, so as to achieve precise adjustment of the patient's position. Medical staff can precisely control the movement distance of the movable block 15 according to the scale, thereby achieving high-precision adjustment of the bowl support 17 and the patient's position, meeting the stringent requirements of neurosurgery for patient position adjustment. In routine care, such as turning over or wiping the patient's body, medical staff can easily tear off the Velcro 19 on the hand straps 18 and leg straps 26 to loosen the straps. After completing the care procedure, the straps can be quickly re-secured using the Velcro 19. The whole process is quick and convenient, greatly improving care efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
