Description

Technical Field

[0001] This utility model relates to the field of anesthesia auxiliary technology, and in particular to a puncture auxiliary device for anesthesia. Background Technology

[0002] Anesthesia refers to various methods used during surgery or diagnostic procedures to eliminate pain, ensure patient safety, and create favorable surgical conditions. It is also used to control pain.

[0003] In the prior art, such as Chinese Patent Publication No. CN220877200U, a puncture auxiliary device for anesthesia in anesthesiology is disclosed. It includes a bed board with two sliding grooves on its upper surface. A slider is slidably installed inside each groove. A support frame is fixedly installed on the upper surface of the two sliders. An adjustment mechanism is fixedly installed on the upper surface of the support frame. The adjustment mechanism includes a movable plate with a toothed plate fixedly installed on its inner wall. A limit groove is formed in the inner wall of the movable plate. A small motor is fixedly installed on the upper surface of the support frame. The power output end of the small motor passes through the movable plate and is fixedly installed with a gear column. The outer surface of the toothed plate meshes with the outer surface of the gear column. This puncture auxiliary device for anesthesiology avoids the problems of uneven puncture force or accidental over-puncture, allowing for better puncture operations. It also increases the ease of disassembling and reassembling syringes and improves compatibility with different syringe models.

[0004] While this patented technology can avoid uneven puncture force or accidental over-puncture, allowing for better puncture procedures, it also requires medical staff to assist in moving the patient when the patient is unconscious or unable to adjust their position for the puncture anesthesia procedure. This is especially true when performing lumbar puncture anesthesia on unconscious patients, as the patient needs to be placed in a lateral decubitus position with their back exposed, which increases the number of medical staff required and thus increases their workload. Utility Model Content

[0005] The purpose of this invention is to address the problem in existing technologies where medical staff must assist and move patients who are unconscious or unable to actively adjust their position to cooperate with puncture anesthesia surgery. This is especially true when performing lumbar puncture anesthesia on unconscious patients, as the lateral decubitus position and back exposure are required, which increases the number of medical staff needed and thus increases their workload. Therefore, this invention proposes a puncture assistance device for anesthesia.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anesthesia puncture auxiliary device, comprising a base, three load-bearing columns welded to the top of the base, a bed board welded between the tops of the load-bearing columns, a limiting column welded to the right side of the bed board near the top, railings symmetrically fixedly connected to the top of the bed board, a second bushing fixedly connected to the rear surface of the bed board, a second rotating shaft rotatably connected to the inner wall of the second bushing, a headrest board rotatably connected to the outer surface of the second rotating shaft, a first bushing fixedly connected to the left surface of the bed board, a first rotating shaft rotatably connected to the inner wall of the first bushing, a lumbar support board rotatably connected to the outer surface of the first rotating shaft, a first slide rail fixedly connected to the bottom of the lumbar support board, a first limiting plate fixedly connected to the right surface of the first slide rail, and a second limiting plate fixedly connected to the left surface of the first slide rail. The base has two fixed posts symmetrically fixedly connected to its top near one edge. The outer surfaces of the two fixed posts are rotatably connected to a first connecting arm via an shaft. The outer surfaces of the two first connecting arms are rotatably connected to a first pulley near their top ends. The first connecting arm is fixedly connected to a first gear via an shaft. The top of the base has a first fixed seat fixedly connected to its top. The right surface of the first fixed seat is rotatably connected to a first worm gear. The left surface of the first fixed seat is rotatably connected to a first handle, and the first handle and the first worm gear are fixedly connected via an shaft. The top of the base has a second fixed seat fixedly connected to its top. A limiter is slidably embedded in the front surface of the base. The second fixed seat has a second worm gear rotatably connected inside. The outer surface of the second worm gear has a first slot near its front end. The front end of the second worm gear is fixedly connected to a second handle.

[0007] Preferably, a limiting rod is fixedly connected to the front surface of the limiter, a restraining post is fixedly connected to the front surface of the base, a spring-loaded rod is fixedly connected to the bottom of the limiter, and a rotating buckle is rotatably connected to the bottom of the limiting rod.

[0008] Preferably, the bottom of the headrest board is symmetrically fixedly connected with a second slide rail, the bottom of the rotating buckle is rotatably connected with a third handle, and the opposite outer surfaces of the base are rotatably connected with two second connecting arms via an axis.

[0009] Preferably, the first connecting arm is symmetrically rotatably connected to a first pulley near its top end, the second connecting arm is rotatably connected to a second pulley near its top end, and the opposite outer surface of the second connecting arm is connected to a second gear via a shaft.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the device adopts a design of two sets of worm gear transmission mechanisms. By rotating the handle operated by medical staff, the worm gear is driven to rotate, which in turn drives the gear to rotate. This power transmission mechanism enables the robotic arm to drive the roller to move smoothly within the preset slide rail, thereby pushing the lumbar support board and the headrest board to achieve rotation. This design aims to conveniently assist patients in adjusting their body position, thereby reducing the workload of medical staff during the anesthesia puncture process.

[0015] 2. In this utility model, when operating this working device, the third handle is rotated to the left, which will drive the rotating buckle to rotate to the left in sync, causing the rotating buckle to disengage from the constraint post. Subsequently, the rebound rod will cause the limiter to be embedded in the first slot, thereby blocking the rotation of the second handle and stopping the mechanical operation of the second worm gear transmission device. This device can provide more stable support for patients when sitting or lying down, and assist patients who have temporarily lost consciousness after puncture anesthesia and need to lie flat, so as to facilitate their physical recovery.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-6As shown, this utility model provides a puncture assistance device for anesthesia, including a base 1. Three load-bearing columns 45 are welded to the top of the base 1. A bed board 11 is welded between the tops of the load-bearing columns 45. A limiting column 15 is welded to the right side of the bed board 11 near the top. A railing 12 is symmetrically fixedly connected to the top of the bed board 11. A second bushing 39 is fixedly connected to the rear surface of the bed board 11. A second rotating shaft 3 is rotatably connected to the inner wall of the second bushing 39. A headrest board 14 is rotatably connected to the outer surface of the second rotating shaft 3. A first bushing 27 is fixedly connected to the left surface of the bed board 11. A first rotating shaft 16 is rotatably connected to the inner wall of the first bushing 27. A waist support plate 13 is rotatably connected to the outer surface of the first rotating shaft 16. A first slide rail 29 is fixedly connected to the bottom of the waist support plate 13. A first limiting plate 25 is fixedly connected to the right surface of the first slide rail 29, and a second limiting plate 26 is fixedly connected to the left surface of the first slide rail 29. Fixed posts 2 are symmetrically fixedly connected to the top of the base 1 near one edge. A first connecting arm 21 is rotatably connected to the opposite outer surfaces of the two fixed posts 2 via an shaft. A first pulley 28 is rotatably connected to the opposite outer surfaces of the two first connecting arms 21 near the top. A first gear 20 is fixedly connected to the first connecting arm 21 via an shaft. The top of the base 1 is fixedly connected to the first gear 20. A first fixed seat 23 is fixedly connected to the base 1. A first worm gear 22 is rotatably connected to the right surface of the first fixed seat 23. A first handle 24 is rotatably connected to the left surface of the first fixed seat 23, and the first handle 24 and the first worm gear 22 are fixedly connected by a shaft. A second fixed seat 36 is fixedly connected to the top of the base 1. A limiter 4 is slidably embedded on the front surface of the base 1. A second worm gear 31 is rotatably connected inside the second fixed seat 36. A first slot 34 is provided on the outer surface of the second worm gear 31 near the front end. A second handle 33 is fixedly connected to the front end of the second worm gear 31. A second slide rail 37 is symmetrically fixedly connected to the bottom of the backrest plate 14. Two second connecting arms 38 are rotatably connected to the opposite outer surfaces of the base 1 via a shaft. A first pulley 28 is symmetrically rotatably connected to the first connecting arm 21 near its top end. A second pulley 35 is rotatably connected to the second connecting arm 38 near its top end. A second gear 32 is connected to the opposite outer surface of the second connecting arm 38 via a shaft. The outer surface of the first worm 22 and the outer surface of the first gear 20 are meshed together. The outer surface of the second worm 31 and the outer surface of the second gear 32 are meshed together. The outer surface of the second pulley 35 slides against the bottom of the second slide rail 37. The outer surface of the first pulley 28 slides against the bottom of the first slide rail 29.

[0026] The overall effect of Embodiment 1 is that, during puncture surgery, the patient's position is adjusted according to anesthesia requirements. Medical staff operate the first handle 24, causing the first worm gear 22 to rotate, which in turn drives the first gear 20 to rotate. The first gear 20 is coaxial with the first connecting arm 21, and its rotation drives the first connecting arm 21 to rotate accordingly. The movement of the first connecting arm 21 causes the first pulley 28 to move smoothly on the first slide rail 29. Due to the linkage mechanism between the lumbar support board 13 and the bed board 11, the left and right movement of the first pulley 28 on the first slide rail 29 can cause the lumbar support board 13 to rotate to the right at a uniform speed, thereby providing the patient with the force to change from a supine to a lateral position, saving the workload of medical staff in moving the patient. When the patient's anesthesia is punctured... When a patient needs to sit, lie down, or rest during a lumbar puncture procedure, medical staff can rotate the second handle 33. This operation will rotate the worm gear, which in turn will rotate the second gear 32. The rotation of the second gear 32 will drive the second connecting arm 38 to rotate accordingly. As the second connecting arm 38 moves, the second pulley 35 moves smoothly on the second slide rail 37. This device can assist medical staff during puncture procedures, helping patients who are unconscious or unable to adjust their posture independently to find a suitable position for lumbar puncture anesthesia. During this process, medical staff only need simple assistance, greatly reducing their workload and the pressure they bear.

[0027] Example 2: Figures 1-6 As shown, a third handle 43 is rotatably connected to the bottom of the rotating buckle 41, a limiting rod 46 is fixedly connected to the front surface of the limiter 4, a restraining post 44 is fixedly connected to the front surface of the base 1, a spring-loaded rod 42 is fixedly connected to the bottom of the limiter 4, a rotating buckle 41 is rotatably connected to the bottom of the limiting rod 46, the top of the limiter 4 and the first slot 34 cooperate with each other, and the top of the rotating buckle 41 and the bottom surface of the restraining post 44 slide against each other.

[0028] The effect achieved by the entire embodiment 2 is that when the third handle 43 is rotated to the left, the drive rotating buckle 41 will rotate to the left in sync, causing the rotating buckle 41 to disengage from the constraint post 44. Subsequently, the rebound rod 42 will cause the limiter 4 to be inserted into the first slot 34, thereby blocking the rotation of the second handle 33 and stopping the mechanical operation of the second worm gear 31 transmission device. This device can provide more stable support for patients when sitting or lying down, assisting patients who have temporarily lost consciousness after puncture anesthesia and need to lie flat, so as to facilitate their physical recovery.

[0029] Working principle: During use, when puncture anesthesia is required, the patient is placed on the lumbar support board 13 in a supine position. Medical personnel operate the first handle 24, causing the first worm gear 22 to rotate. This rotation further drives the first gear 20 to rotate. The first gear 20 is coaxially connected to the first connecting arm 21. Therefore, the rotation of the first gear 20 will drive the first connecting arm 21 to rotate synchronously. With the movement of the first connecting arm 21, the first pulley 28 slides smoothly on the first slide rail 29. Given the specific linkage mechanism between the lumbar support board 13 and the bed board 11, the left and right movement of the first pulley 28 on the first slide rail 29 will cause the lumbar support board 13 to rotate to the right at a uniform and stable speed. When the patient needs to be in a sitting or lying position for anesthesia puncture surgery, Medical staff can rotate the second handle 33, which will drive the worm gear to rotate, thereby causing the second gear 32 to rotate. The rotation of the second gear 32 will drive the second connecting arm 38 to rotate accordingly. With the movement of the second connecting arm 38, the second pulley 35 moves smoothly on the second slide rail 37. When adjusted to the appropriate position, the medical staff can turn the third handle 43 to the left. At this time, the rotating buckle 41 will be driven to rotate to the left in sync, causing the rotating buckle 41 to disengage from the constraint post 44. Subsequently, the rebound rod 42 will cause the limiter 4 to be inserted into the first slot 34, thereby blocking the rotation of the second handle 33 and stopping the mechanical operation of the second worm gear 31 transmission device. During this process, the headrest board 14 will be pushed to move upward or downward to meet the patient's rest needs.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
