Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a lumbar puncture limiting pillow for children. Background Technology
[0002] Lumbar puncture is a commonly used clinical diagnostic and treatment procedure. It is a medical procedure in which a puncture needle is inserted into the intervertebral space to extract cerebrospinal fluid or inject drugs. It can be used to diagnose various inflammatory diseases of the central nervous system, vascular diseases, spinal cord lesions, suspected intracranial space-occupying lesions, neurological diseases with unclear diagnoses, pneumocephalus, and myelography. It is also used to drain (decompress) cerebrospinal fluid and inject drugs to treat central nervous system diseases caused by excessively high cerebrospinal fluid pressure.
[0003] Lumbar puncture requires a specific patient position: head to chest, knees to chest, and hands clasped around the knees, to maximize exposure of the L3-L4 intervertebral space. However, when performing lumbar puncture on children, their young age makes it difficult for them to understand the necessity of the procedure, often resulting in fear and resistance. Furthermore, they may struggle to maintain a fixed position for extended periods, leading to inaccurate positioning and impacting the success rate and safety of the puncture. After positioning and disinfection, the child's position often changes, requiring repositioning before lumbar puncture can be performed, increasing the workload and time required for medical staff. Utility Model Content
[0004] The purpose of this invention is to provide a lumbar puncture positioning pillow for children that can stabilize the child's position, improve operational efficiency, ensure high safety, and save time and effort. This addresses the technical problem that children's position is unstable and difficult to maintain for a long time during lumbar puncture due to fear and resistance, which affects the success rate and safety of the puncture and increases the workload and operation time of medical staff.
[0005] To solve the above technical problems, the solution adopted by this utility model is as follows: A pediatric lumbar puncture positioning pillow includes a positioning pillow and a fixation device. The positioning pillow has a head fixation groove, a hand fixation groove, and a leg fixation groove. The hand fixation groove is located on both sides of the head fixation groove. There are two hand fixation grooves and two leg fixation grooves. The fixation device includes a head restraint strap, a hand restraint strap, a waist restraint strap, and a leg restraint strap. The two ends of the head restraint strap are respectively installed on both sides of the head fixation groove. There are two hand restraint straps, which are respectively connected to the hand fixation grooves on both sides of the head fixation groove. The two ends of the waist restraint strap are connected to both sides of the middle part of the positioning pillow. There are two leg restraint straps, which are respectively connected to both sides of the two leg fixation grooves. The top of the positioning pillow is arc-shaped to fit the child's abdomen, making it convenient for the child to bend over. The outside of the positioning pillow is wrapped with velvet to ensure the child's comfort, and the inside is filled with latex, which has a certain degree of elasticity and support to prevent the positioning pillow from deforming.
[0006] The child lies on their side on the hospital bed, and a positioning pillow is placed in their arms, with its curved side conforming to the child's abdomen after bending at the waist. The head, hands, and legs are placed in their respective fixing grooves and secured with head, hand, waist, and leg restraints. The overall effect is similar to the child tightly hugging the positioning pillow, fixing the child in place and preventing them from loosening their grip. This ensures the child maintains a stable position during the procedure and effectively prevents the puncture site from shifting due to movement, thus guaranteeing the accuracy of the puncture. The hand fixing groove is shaped to surround the head fixing groove, effectively restricting the range of hand movement. The curved design of the positioning pillow matches the curve of the human waist, allowing the child's waist to be in a suitable bending position, facilitating subsequent lumbar puncture procedures by medical staff.
[0007] Furthermore, the positioning pillow is equipped with a leg pad and an adjustable connecting rope; one end of the adjustable connecting rope is connected to the head fixing groove of the positioning pillow, and the other end is connected to the middle of the leg pad; the leg pad is equipped with two limiting bands A.
[0008] When using the device, have the child lie on their side holding the positioning pillow, assuming the correct lumbar puncture position. Position the knees close to the center of the bottom plane of the positioning pillow. Place the leg pads between the child's legs, placing them horizontally so the child can easily grip the ends of the leg pads with their knees. Secure the device using the two limiting straps A. Adjust the length of the adjustable connecting rope to bring the child's legs closer to the bottom of the positioning pillow, applying a pulling force to the knees and ensuring they are in contact with the center of the positioning pillow's plane. Keep the knees as close to the child's abdomen as possible to prevent straightening the legs, ensuring leg stability during the procedure. This facilitates the puncture procedure, improves stability, and provides support for the child's legs, reducing discomfort from maintaining the correct knee flexion position and thus alleviating leg fatigue.
[0009] Furthermore, the fixing device includes two fixing ropes and a fixing adjustment buckle; the middle part of the two fixing ropes is fixedly connected to both ends of the rear side of the positioning pillow, and the two ends are connected by the fixing adjustment buckle. When in use, the positioning pillow is perpendicular to the hospital bed, with the side with the fixing ropes in contact with the hospital bed. The middle part of the two fixing ropes is fixedly connected to both ends of the rear side of the positioning pillow. Combined with the fixing adjustment buckles at both ends of the fixing ropes, a ring-shaped fixing structure is formed to fix the positioning pillow to the hospital bed, preventing the positioning pillow from moving during puncture operations or when the child moves around. The length of the fixing ropes can be adjusted by the fixing adjustment buckle to adapt to different sized hospital beds.
[0010] Furthermore, the head restraint, hand restraint, waist restraint, and leg restraint are elastic bandages. The elastic bandages are designed to secure children of different body types, offering a wide range of adaptability. The elastic bandages are connected via Velcro or fasteners.
[0011] The working principle of this utility model is as follows: When using the device, place the child on the bed in a side-lying position with their back perpendicular to the bed surface. Place the positioning pillow in the child's lap. Adjust the head, arms, and thighs to fit into the head, hand, and leg fixation grooves, respectively, keeping the legs in a bent-knee position. Secure the child's head, waist, and limbs using elasticated straps for head, hand, waist, and leg restraints. The leg restraints are positioned 3-5 cm below the child's groin, with the leg fixation groove fitting snugly against the groin. Secure the device with a rope and adjustable buckles. The positioning pillow is fixed to the hospital bed. The leg pads are inserted into the knee area of both legs in the leg fixing grooves, and the legs are fixed by the limiting strap A. The length of the adjustable connecting rope is adjusted so that the child's thighs are in contact with the bottom of the positioning pillow, ensuring that the legs remain stable during the operation and providing support for the child's legs. This reduces the fatigue of maintaining the position for a long time while ensuring the child's puncture position, ensuring the child's stable and comfortable position. Medical staff can quickly complete the positioning and disinfection of the lumbar puncture while the child is in a fixed position, reducing the time spent on repeated position adjustments and improving the efficiency of the operation.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model can effectively fix the child's head, hands and legs, so that the child can maintain a stable position during the operation. Combined with the arc-shaped positioning pillow that conforms to the curve of the human waist, it can keep the child's waist in a proper bending state, which is convenient for medical staff to perform puncture operations. Overall, it can effectively reduce the time spent on repeated adjustments of the body position, and at the same time, it can avoid the movement of the puncture position due to random movements. It has high safety and effectively improves the overall operation efficiency.
[0013] 2. This utility model can effectively support the child's legs with the leg pad and adjustable connecting rope, ensuring leg stability. The positioning pillow is firmly fixed to the hospital bed by the design of the fixing rope and the fixing adjustment buckle, preventing the positioning pillow from shifting due to the child's movement or external force during operation, and the overall stability is high.
