Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a human fixation device suitable for lumbar puncture in children. Background Technology

[0002] Lumbar puncture is a common diagnostic and treatment method, often used for cerebrospinal fluid examination, drug injection, and treatment of certain neurological disorders (such as abnormal intracranial pressure and central nervous system infections). Before a lumbar puncture, the patient usually assumes a lateral decubitus position with their back perpendicular to the bed, head flexed towards the chest, and hands clasped to the knees and abdomen, forming an arched shape with the torso. This posture helps widen the intervertebral space, facilitating needle insertion. However, children require special attention during lumbar punctures due to their smaller size and increased sensitivity to pain. A child's lack of cooperation increases the workload for the assistant, ultimately leading to lower puncture efficiency and difficulties in achieving aseptic technique.

[0003] There are few inventions of lumbar puncture fixation devices specifically for children, and they mainly fall into two categories: one is the wearable type, where the patient wears a restraint garment or straps, and the length and tightness of the device are adjusted to create a fixed angle between the limbs and the torso. However, this type of device requires active cooperation from the patient and is difficult to fix the patient's arms, especially the forearms. When children feel discomfort in the lumbar puncture position, they are prone to pulling or breaking free of the restraints, still requiring the assistance of an assistant.

[0004] The second type is the bed-based type, where the device is connected to the bed and achieves lumbar spine exposure and stretching by adjusting and fixing the patient's posture. However, this type of device often only restrains the patient's upper limbs, resulting in poor restraint and leaving considerable room for movement. In clinical practice, children's fear can cause them to struggle, making it difficult to achieve the desired fixation effect. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a human fixation device suitable for lumbar puncture in children, which can provide good restraint function to significantly reduce the range of human movement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A human immobilization device suitable for lumbar puncture in children, comprising:

[0008] The bed body has a mounting surface formed on it;

[0009] A chest restraint device is provided on an installation surface. The chest restraint device includes a first restraint surface and a first restraint strap. The first restraint strap is used to bind a human body to restrain the chest cavity of the human body to the first restraint surface.

[0010] A waist guide assembly, wherein the waist guide assembly is a guide plate, the guide plate is used to attach to the waist of the human body, and the guide plate is provided with guide perforations;

[0011] A leg restraint device, wherein the leg restraint device is rotatably connected to a mounting surface, the leg restraint device includes a second restraint surface and a second restraint strap, the second restraint strap being used to bind the human body to the second restraint surface.

[0012] As a further improvement of the present invention, the leg restraint device includes a rotating cylinder, a rotating column is provided on the mounting surface, the rotating column passes through the rotating cylinder and is rotatably connected to the rotating cylinder, and a limiting component is provided between the rotating column and the rotating cylinder, the limiting component being used to restrict the rotating cylinder from rotating relative to the rotating column in a direction away from the chest restraint device.

[0013] As a further improvement of the present invention, the rotating cylinder has an installation cavity at its end, the rotating column has an adjustment cavity along its length, the adjustment cavity has an opening at the end of the rotating column away from the bed, the adjustment cavity has an adjustment column and a spring, one end of the adjustment column is connected to the spring, and the other end has a button corresponding to the opening, the side of the rotating column has a sliding groove communicating with the adjustment cavity, the limiting component includes a ratchet and a pawl, the ratchet is disposed corresponding to the adjustment cavity and sleeved on the outside of the rotating column, the adjustment column has a connecting piece extending from the sliding groove and connected to the ratchet, and the pawl is disposed in the installation cavity and corresponds to the ratchet.

[0014] As a further improvement of the present invention, both the chest restraint device and the leg restraint device include a mounting base, and the mounting base is provided with a retractor for retracting the first restraint strap / second restraint strap.

[0015] As a further improvement of the present invention, the bed body is provided with a first adjustment groove corresponding to the chest restraint device, and a first adjustment block is slidably provided in the first adjustment groove. The chest restraint device is detachably connected to the first adjustment groove, and the first adjustment block is used to drive the chest restraint device to slide along the length direction of the first adjustment groove.

[0016] As a further improvement of the present invention, the bed body is provided with a second sliding groove corresponding to the leg restraint device, and a second adjusting block is provided in the second sliding groove. The rotating column is provided with a limit surface threadedly connected to the end of the rotating column. The limit surface is used to abut against one end of the rotating cylinder to restrict the rotating cylinder from moving along the axis of the rotating column.

[0017] As a further improvement of the present invention, the bed body includes a base and a bed board, the base being provided with an adjustment device, the adjustment device being connected to the bed board and used to adjust the angle of the bed board relative to the base.

[0018] As a further improvement of the present invention, one side of the guide plate extends outward to form a connecting part and is rotatably connected to the chest binding device through the connecting part. A spring is provided at the connection point of the connecting part. The spring is connected to the connecting part and is used to drive the connecting part to swing in the direction of the first binding surface. A locking member is provided on the chest binding device. The locking member is used to restrict the rotation of the connecting part relative to the chest binding device.

[0019] As a further improvement of the present invention, a toothed ring is formed on the connecting part, and the locking member is a pressing block. The pressing block has locking teeth at its end, and the locking teeth are used to engage the toothed ring to limit the rotation of the toothed ring.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting up chest and leg restraint devices, the upper and lower body of the human body can be restrained. The upper and lower arms of the patient can be restrained by first crossing the restraint straps on the left and right and then fastening them horizontally, thereby greatly reducing the patient's mobility and improving the restraint effect.

[0022] 2. The guide plate can expose the lumbar spine position, thereby providing guidance for medical staff to perform the puncture. At the same time, the puncture plate can also limit the position of the patient's lumbar spine to reduce the movement of the lumbar spine, thereby further improving the restraint and fixation effect on the patient and ensuring a sterile operating environment.

[0023] 3. By installing a rotating shaft on the leg support assembly, it can rotate freely while perpendicular to the bed. First, extend the leg support assembly outward so that the angle between it and the chest device is greater than 90 degrees, facilitating the patient's side-lying entry. Then, slowly rotate the axle to reduce the angle between the legs and the chest support device, allowing the patient to adapt to the process of the thighs approaching the chest, ultimately maintaining the chest close to the abdomen and the torso in an arched position for lumbar puncture. This design reduces patient discomfort during the fixation process and avoids causing additional injury to the child during the procedure.

[0024] 4. Given that this invention primarily targets pediatric patients, to avoid causing fear in children, the vertical design of the cylinder and bed board allows patients to easily lie on their side and enter the device, using gravity to stabilize their bodies. A heating device further enhances the overall comfort of the patient by heating the guide plate.

[0025] 5. This invention provides a lumbar puncture fixation device that is simple in structure, convenient in operation, and provides good fixation, especially suitable for children, solving the problem of children's lack of cooperation and reducing workload. Furthermore, the device is simple in design, easy for medical staff to adjust, ensures a sterile operating environment, and improves the efficiency of lumbar puncture. Attached Figure Description

The limiting rod 15 is used to pass through the first adjustment block 14 to limit the movement direction of the first adjustment block 14.

[0037] In this embodiment, the first adjusting block 14 is provided with a connecting rod 16, which is used to insert into the bottom of the mounting seat 9 corresponding to the chest restraint device 8 to complete the detachable connection. Furthermore, a bolt hole is provided on one side of the mounting seat 9, which is used for bolts to pass through the mounting seat 9 and the connecting rod 16 to achieve complete fixation of the connecting rod 16 and the mounting seat 9.

[0038] In order to improve patient comfort, the inner side of the mounting base 9 is a first restraint surface 17, on which a soft padding layer can be provided. The soft padding layer includes an air cushion, a silicone pad, or other soft materials or methods.

[0039] Preferably, it also includes a lumbar guiding device, specifically a guide plate 18, which is used to attach to the waist of the human body. The guide plate 18 is provided with a guide hole 19, which facilitates the exposure of the surgical field to facilitate positioning and operation by medical staff. At the same time, the guide plate 18 can also further restrict the patient's waist to further enhance the overall restraint and fixation effect.

[0040] Specifically, the guide plate 18 extends outward on one side to form a connecting part 20, which is rotatably connected to the chest binding device 8.

[0041] Specifically, the mounting base 9 corresponding to the chest restraint device 8 forms connecting rings 23 at both ends of the connecting part 20. The two connecting rings 23 are respectively rotatably sleeved on both ends of the connecting part 20 to realize the rotatable connection between the connecting part 20 and the mounting base 9. The spring 21 is located between one of the connecting parts 20 and the connecting ring 23. The toothed ring 24 is provided at the end of the connecting part 20. The locking member 22 is a pressing block 25. The end of the pressing block 25 is provided with locking teeth 26. The locking teeth 26 are used to engage the toothed ring 24 to restrict the rotation of the toothed ring 24.

[0042] Furthermore, to improve overall comfort, a heating plate is provided on the side of the guide plate 18 that is attached to the human body.

[0043] Preferably, it also includes a leg restraint device 27, which is rotatably connected to the mounting surface 4. The leg restraint device 27 includes a second restraint surface 28 and a second restraint strap 29, which is used to restrain the human leg to the second restraint surface 28.

[0044] The leg restraint device 27 also includes a mounting base 9. The bed board 3 is provided with a rotating column 34 and is rotatably connected to the mounting base 9. The mounting base 9 corresponding to the leg restraint device 27 is provided with a second restraint strap 29. Similarly, the second restraint strap 29 is wound up by a retractor 10 provided on the mounting base 9.

[0045] Furthermore, the bed body 1 is provided with a second sliding groove 30 corresponding to the leg restraint device 27. The second sliding groove 30 is provided with a second adjusting block 31. The rotating column 34 is provided with a corresponding adjusting block. The end of the rotating column 34 is threadedly connected to a limiting surface 32. The limiting surface 32 is used to abut against one end of the rotating cylinder 33 to restrict the rotating cylinder 33 from moving along the axis of the rotating column 34. In use, the limiting surface 32 can be disassembled by thread to separate the rotating column 34 and the rotating cylinder 33, thereby achieving a cleaning effect in conjunction with the disassembly of the chest restraint device 8.

[0046] Furthermore, the leg restraint device 27 includes a rotating cylinder 33, and a rotating column 34 is provided on the mounting surface 4. The rotating column 34 passes through the rotating cylinder 33 and is rotatably connected to the rotating cylinder 33. A limiting component 35 is provided between the rotating column 34 and the rotating cylinder 33. The limiting component 35 is used to restrict the rotating cylinder 33 from rotating relative to the rotating column 34 in a direction away from the chest restraint device 8.

[0047] Specifically, the rotating cylinder 33 has an installation cavity 36 at its end, the rotating column 34 has an adjustment cavity 37 along its length, the adjustment cavity 37 has an opening 38 at the end of the rotating column 34 away from the bed 1, the adjustment cavity 37 has an adjustment column 39 and a spring 40, one end of the adjustment column 39 is connected to the spring 40, and the other end forms a button part 41 corresponding to the opening 38, the side of the rotating column 34 has a groove 42 that communicates with the adjustment cavity 37, the limiting component 35 includes a ratchet 43 and a pawl 44, the ratchet 43 is set in the adjustment cavity 37 and sleeved on the outside of the rotating column 34, the adjustment column 39 has a connecting piece extending from the groove 42 and connected to the ratchet 43, and the pawl 44 is set in the installation cavity 36 and corresponds to the ratchet 43.

[0048] In the initial state, driven by the elastic force of the spring 40, the connecting piece is located at the top of the slide groove 42. At this time, the ratchet 43 and the pawl 44 correspond, so that the pawl 44 can limit the ratchet 43, so that the rotating cylinder 33 can only rotate in the direction of the first restraint surface 17. Thus, the angle of the leg restraint device 27 can be adjusted by the ratchet 43 and the pawl 44 to fully adapt to the body conditions of different patients and achieve complete fixation. After use, by pressing the button part 41, the adjusting column 39 is moved, so that the ratchet 43 and the pawl 44 are separated. At this time, the rotating cylinder 33 can reverse relative to the rotating column 34, so as to facilitate subsequent disassembly and separation.

[0049] The implementation principle of a human fixation device for lumbar puncture in children according to an embodiment of this application is as follows: Medical staff lift the bed board 3 using cylinder 7, making the bed board 3 as perpendicular to the base 2 as possible. At this time, the position of the leg restraint device 27 can be adjusted through the second adjustment groove. The patient then sits on the mounting seat 9 corresponding to the leg restraint device 27, and the chest cavity and waist are brought into contact with the chest restraint device 8 and the waist guide component by natural gravity. At this time, the position of the chest restraint device 8 can be adjusted through the first adjustment groove 13 to align it with the patient's chest cavity, and the first restraint strap 11 is used to... The patient is pre-fixed with the second restraint belt 29. The bed board 3 is then leveled again using the cylinder 7. At this point, the tilt angle of the leg restraint device 27 can be adjusted by slightly rotating the rotating cylinder 33. The first restraint belt 11 and the second restraint belt 29 are then readjusted to completely fix the patient's chest and leg positions. The guide plate 18 is then rotated to attach to the patient's lumbar spine. After the position adjustment is completed, the angle of the guide plate 18 is completely fixed by pressing the locking piece 22. Finally, medical staff complete the lumbar puncture through the guide puncture hole 19.
