Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an auxiliary fixing bracket for anesthesia. Background Art

[0002] During the clinical treatment process, sometimes anesthetic equipment is needed to anesthetize patients, and during the use process, anesthetic pipelines made of soft rubber are used for drug delivery. To ensure safety and stability, generally, anesthetic brackets are used to support and position the pipelines.

[0003] For example, the Chinese patent with the publication number "CN211050644U" discloses "an anesthetic bracket dedicated to fixing anesthetic pipelines". Its main structure includes a U-shaped fixing seat. A through groove is provided at the rear end inside the U-shaped fixing seat. Hinge seats are provided on both sides inside the U-shaped fixing seat. A fixing clamp is hinged to the inner surface of the hinge seat. A guiding roller is rotatably installed at the front end inside the fixing clamp. A conical plate is provided at the rear side of the fixing clamp. The outer surface of the conical plate is slidably connected to the inner surface of the through groove. A spring groove is provided on the inner surface of the conical plate. A return spring is fixedly installed on the inner surface of the spring groove. A support rod is fixedly connected to the upper surface of the U-shaped fixing seat. A circular hole is provided at the upper end inside the support rod. A circular rod is rotatably connected to the inner surface of the circular hole. For this anesthetic bracket dedicated to fixing anesthetic pipelines, by installing a friction wheel in the inclined track through groove inside the positioning box, the pressing force can be adjusted to avoid excessive extrusion and is easy to position; by arranging the track through groove obliquely, the height of the friction wheel can be adjusted, and then the pressing gap can be adjusted to avoid loosening and excessive extrusion, which is convenient and stable.

[0004] However, after the above-mentioned anesthetic bracket dedicated to fixing anesthetic pipelines fixes the anesthetic pipeline, since the path of the pipeline will change during the working process, and after the anesthetic pipeline is fixed by this anesthetic bracket, it cannot adaptively change the clamping angle according to the path change of the pipeline, which easily leads to the phenomenon that the inner diameter of the pipeline is blocked due to excessive bending at the clamping part, seriously leading to harmful changes in the anesthetic dose, and there are relatively large potential safety hazards in use. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 and Figure 2 , an auxiliary fixing bracket for anesthesia, including a ring-shaped support plate 1 with a component fixing hole 4 provided at the center, two longitudinally supported rods 2 fixedly installed at the bottom of the ring-shaped support plate 1 and symmetrically arranged, and a bottom mounting plate 3 fixedly installed at the bottom of the longitudinally supported rod 2. The bottom mounting plate 3 is fixedly installed at the corresponding position of a common support frame or equipment required for work.

[0024] In order to realize the control functions of the adaptable angle and clamping force of the anesthesia pipeline, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set an adjustable-angle movable mechanism 5, which internally has a longitudinal hollow housing 51 with some structures fixedly installed inside the component fixing hole 4 and a hollow interior, a hemispherical hollow housing 53 integrally provided at the top of the longitudinal hollow housing 51 and having a hollow interior, a rotating ball head 58 placed inside the hemispherical hollow housing 53 and capable of rotating relative to the hemispherical hollow housing 53, a braking column 514 placed inside the longitudinal hollow housing 51 and with its top abutting against the bottom of the rotating ball head 58, and a first helical spring 512 capable of controlling the frictional resistance between the braking column 514 and the rotating ball head 58. When the external threaded rod 513 is rotated directionally, due to the threaded connection structure, the external threaded rod 513 will drive the lower limit movable plate 510 to move longitudinally, thereby changing the distance between the lower limit movable plate 510 and the upper limit movable plate 511, and then changing the elastic strength of the first helical spring 512. Since the frictional force between the braking column 514 and the rotating ball head 58 comes from the above elastic strength, therefore, the torque resistance that the rotating ball head 58 needs to overcome during rotation can be changed. When the path of the pipeline changes, different-direction forces will be generated on the lower clamping plate 61 and the upper clamping plate 62, and this force will be transmitted between the rotating ball head 58 and the braking column 514. When this force is greater than the torque resistance, the rotating ball head 58 will undergo an adaptive angle change, thereby realizing the control functions of the adaptive angle and clamping force of the anesthesia pipeline.

[0025] For the specific structure of the adjustable-angle movable mechanism 5, please refer to Figure 3 and Figure 4, including a longitudinal hollow housing 51 with its bottom structure fixedly installed in the component fixing hole 4. The outer circumferential surface of the longitudinal hollow housing 51 is provided with a middle connecting plate structure 52 which is integrally formed with it and fixedly installed on the upper surface of the annular support plate 1. The top end of the longitudinal hollow housing 51 is provided with a hemispherical hollow housing 53 which is integrally formed with it. The interior of the hemispherical hollow housing 53 is provided with a hemispherical cavity 57 with an open top. Inside the hemispherical hollow housing 53 and located within the hemispherical cavity 57 is placed a rotating ball head 58. The top structure of the rotating ball head 58 is provided with a top connecting plate 59 which is integrally formed with it. The interior of the longitudinal hollow housing 51 is provided with a longitudinal component moving cavity 54. The bottom end of the longitudinal hollow housing 51 is provided with an internal thread hole 55 that communicates the external space and the bottom end of the longitudinal component moving cavity 54. The top of the longitudinal hollow housing 51 is provided with a first component through hole 56 that communicates the top end of the longitudinal component moving cavity 54 and the bottom of the hemispherical cavity 57. Inside the longitudinal hollow housing 51 and located within the longitudinal component moving cavity 54 are placed a lower limit moving plate 510 and an upper limit moving plate 511 that can move axially along the longitudinal component moving cavity 54. Between the lower limit moving plate 510 and the upper limit moving plate 511 is placed a first helical spring 512 in a compressed state. The bottom end of the lower limit moving plate 510 is installed with an external threaded rod 513 that can rotate and penetrates the internal thread hole 55. The external threaded rod 513 is installed in the internal thread hole 55 through a threaded structure. The top end of the upper limit moving plate 511 is fixedly installed with a braking column 514 that penetrates the first component through hole 56 and whose top end abuts against the bottom of the rotating ball head 58. The structural shape of the cross-section of the longitudinal component moving cavity 54 is the same as the structural shape of the cross-sections of the lower limit moving plate 510 and the upper limit moving plate 511, both being polygonal structures, and the structural dimensions of the cross-section of the longitudinal component moving cavity 54 match the structural dimensions of the cross-sections of the lower limit moving plate 510 and the upper limit moving plate 511. The threaded structure includes an internal thread structure provided in the internal thread hole 55 and an external thread structure provided on the rod body of the external threaded rod 513, and the internal thread structure matches the external thread structure. The height of the braking column 514 is greater than the depth of the first component through hole 56, and the top end of the braking column 514 is provided with a concave structure, and this concave structure is consistent with the arc structure on the surface of the rotating ball head 58.

[0026] To achieve the elastic clamping function of the anesthesia pipeline, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up a rotating elastic clamping mechanism 6, which is internally provided with a lower clamping plate 61 fixedly installed on the top of the top connecting plate 59, an upper clamping plate 62 that cooperates with the lower clamping plate 61 to clamp the pipeline, and a No. 2 coil spring 68 that can control the clamping force between the lower clamping plate 61 and the upper clamping plate 62. Pull the upper clamping plate 62 upward. At this time, the lower clamping plate 61 and the upper clamping plate 62 are separated, and then the anesthesia pipeline to be clamped is placed between the two clamping grooves 64, and then the pulling force on the upper clamping plate 62 is released. Under the action of the No. 2 coil spring 68, the anesthesia pipeline is elastically clamped, and the elastic clamping can achieve stable clamping and avoid excessive squeezing.

[0027] For the specific structure of the rotating elastic clamping mechanism 6, please refer to Figure 5 and Figure 6 , including a lower clamping plate 61 and an upper clamping plate 62, the bottom of the lower clamping plate 61 is provided with a bottom connecting plate 63 which is an integral structure with it and fixedly mounted on the top of the top connecting plate 59, the lower clamping plate 61 and the upper clamping plate 62 are provided with symmetrical clamping grooves 64 on opposite surfaces, the lower clamping plate 61 and the upper clamping plate 62 are provided with corresponding No. 2 component through-holes 65, a longitudinal movable rod 66 is inserted into the No. 2 component through-hole 65, and an end limit plate 67 is fixedly mounted on both ends of the longitudinal movable rod 66, and two No. 2 coil springs 68 are installed on the rod body of the longitudinal movable rod 66 so that the lower clamping plate 61 and the upper clamping plate 62 are in contact with each other with elastic force.

[0028] When in use, the bottom mounting plate 3 is fixedly installed on a common support frame or a corresponding position of the equipment required for work, and the external threaded rod 513 is rotated in a directional manner. Due to the threaded structure connection, the external threaded rod 513 will drive the lower limit movable plate 510 to move longitudinally, thereby changing the elastic strength of the No. 1 coil spring 512. Since the friction force between the brake column 514 and the rotating ball head 58 comes from the above-mentioned elastic strength, it is possible to change the torque resistance that the rotating ball head 58 needs to overcome when rotating, and pull the upper clamping plate 62 upward. At this time, the lower clamping plate 61 and the upper clamping plate 62 are separated, and then the anesthesia pipeline to be clamped is placed between the two clamping grooves 64, and then the pulling force on the upper clamping plate 62 is released. Under the action of the No. 2 coil spring 68, the anesthesia pipeline is elastically clamped.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
