Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical auxiliary device technology, and in particular relates to an auxiliary stent for clinical anesthesia in medicine. Background Technology
[0002] In clinical anesthesia procedures, auxiliary stents must simultaneously meet functional requirements such as tube clamping, tool placement, and flexible movement. Existing technologies, such as the Chinese utility model patent with authorization announcement number CN221383781U, disclose an auxiliary stent for clinical anesthesia. This stent achieves height adjustment, auxiliary placement frame loading / unloading, and overall movement through a combination design of a movable chassis, rollers, and lifting hollow tube plugs. However, this technical solution still has significant drawbacks: although the device can reduce some components by loading and unloading the auxiliary placement frame, the stent body, movable chassis, and lifting structure are all integrated designs, lacking a modular folding or retracting mechanism. This results in a high space occupancy rate during transportation and storage, especially exacerbating the space management burden in scenarios with multiple devices. To address these shortcomings, we propose an auxiliary stent for clinical anesthesia. Utility Model Content

[0030] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of an auxiliary stent for clinical anesthesia.
[0031] like Figure 1-7 As shown, this utility model provides an auxiliary support for clinical anesthesia, comprising: a foldable base, a drug placement rack, and a cable management structure.
[0032] The foldable base includes a bottom support frame 10, a caster wheel 11 located at the bottom of the bottom support frame 10, a folding inclined support 13 rotatably connected to the left end of the upper surface of the bottom support frame 10 via a first pivot 12, and a support assembly located between the folding inclined support 13 and the bottom support frame 10. The caster wheel 11 has a braking function.
[0033] The support assembly includes a support rod 41 hinged to the right side of the folding inclined support 13 via a third pivot 40, a mounting cylinder 42 fixedly connected to the bottom end of the support rod 41, a through mounting groove opened along the axial direction of the mounting cylinder 42, symmetrical limiting pins 43 slidably disposed in the mounting groove, a limiting frame 44 fixedly disposed on the upper surface of the bottom support frame 10 and having a limiting groove, and a bidirectional compression spring 45 disposed inside the mounting groove. The two ends of the bidirectional compression spring 45 respectively abut against the opposite end faces of the two limiting pins 43. The forward and backward sliding stroke of the limiting pins 43 is constrained by the length of the mounting groove. The limiting groove of the limiting frame 44 and the end of the limiting pin 43 form an insertion fit. The support rod 41 is hinged to the folding inclined support 13 via the third pivot 40. The bidirectional compression spring 45 in the mounting cylinder 42 drives the limiting pins 43 to slide along the mounting groove. The end of the limiting pin 43 is embedded in the limiting groove of the limiting frame 44 to achieve fixation.
[0034] The first pivot 12 enables the folding inclined support 13 to be rotatably connected to the bottom support frame 10. The bidirectional compression spring 45 in the support assembly pushes the symmetrical limit pin 43 to slide outward and insert it into the limit groove of the limit frame 44 to form a rigid lock. The insertion and cooperation between the limit pin 43 and the limit frame 44 achieves quick mechanical locking and strong support stability. When folding, pressing the limit pin 43 disengages it from the limit groove, and the support rod 41 rotates around the third pivot 40 to fold.
[0035] The drug placement rack includes a second rotating shaft 20 rotatably connected to the inner wall of the upper end of the folding inclined support 13, a gas spring 21 vertically fixed to the outer peripheral surface of the second rotating shaft 20, a drug placement assembly disposed at the top of the gas spring 21, and a limiting assembly acting on the second rotating shaft 20.
[0036] The medicine placement assembly includes a horizontally positioned medicine placement tray 50, a T-shaped frame 51 fixedly connected to the top of a gas spring 21 via a connecting flange, threaded posts 52 symmetrically arranged on the top of both sides of the T-shaped frame 51, a through hole 53 on one side of the medicine placement tray 50 that mates with the threaded post 52, and a locking nut 54 threadedly connected to the upper end of the threaded post 52. The medicine placement tray 50 is inserted into the threaded post 52 through the through hole 53, and the locking nut 54 is rotated to press and fix it, thereby fixing the medicine placement tray 50 on the T-shaped frame 51.
[0037] The limiting assembly includes a limiting plate 60 coaxially fixed to the outer periphery of the second rotating shaft 20, a transverse through hole opened at the front end of the folding inclined support 13, a pull bolt 61 slidably inserted into the through hole, a return spring 62 sleeved on the outer periphery of the pull bolt 61, and two positioning holes 63 symmetrically arranged on the edge of the limiting plate 60. One end of the return spring 62 is fixed to the outer surface of the folding inclined support 13, and the other end is connected to the operating end of the pull bolt 61. The insertion end of the pull bolt 61 selectively engages with the positioning hole 63.
[0038] The gas spring 21 is rotatably connected to the folding inclined support 13 via the second rotating shaft 20. The pull bolt 61 is inserted into the positioning hole 63 of the limiting plate 60 by the elastic force of the return spring 62, which restricts the rotation of the second rotating shaft 20 and fixes the rotation angle of the gas spring 21. After pulling the pull bolt 61 out of the positioning hole 63, the angle of the gas spring 21 can be adjusted.
[0039] The two-stage folding joint formed by the first pivot 12 and the second pivot 20, combined with the plug-in and separation design of the support component and the limiting frame 44, reduces the volume of the device after folding, significantly reducing the space occupied by the equipment. The bidirectional compression spring 45 of the support component drives the symmetrical limiting pin 43 to automatically lock with the limiting frame 44. With the dual-point locking of the pull bolt 61 and the positioning hole 63, the folding inclined support 13 and the gas spring 21 can be quickly unfolded and stored.
[0040] The cable management structure includes multiple sets of elastic buckles 30 spaced apart on the outer surface of the folding inclined support 13 and around the outer periphery of the gas spring 21 rod. The elastic buckles 30 are made of silicone and fix the cables through pre-deformation clamping force. This device can simultaneously realize the functions of medicine placement, pipeline fixing, height adjustment and movement, reducing the number of auxiliary equipment.
[0041] Working principle:
[0042] Equipment unfolding operation: The folding inclined support 13 is rotatably connected to the bottom support frame 10 via the first rotating shaft 12. The bidirectional compression spring 45 in the support assembly pushes the symmetrical limit pin 43 to slide outward, so that its end is inserted into the limit groove of the limit frame 44. The support rod 41 supports the folding inclined support 13, forming a rigid mechanical lock to ensure the stability of the bracket when unfolding. Then, after pulling the bolt 61 to overcome the elastic force of the return spring 62, the positioning hole 63 of the limit plate 60 is unlocked. Then, the gas spring 21 can be rotated to make it perpendicular to the bottom support frame 10. Then, the bolt 61 is released so that it is inserted into the positioning hole 63 under the action of the return spring 62, realizing the double-position locking of the gas spring 21, thereby allowing the device to be fully unfolded.
[0043] Installation of the medicine placement tray 50: Align the through hole 53 of the medicine placement tray 50 with the threaded post 52 of the T-shaped frame 51 and insert it. Rotate the locking nut 54 to tighten and fix it, thus completing the quick pick-up and drop-off of sterile tools.
[0044] The cable management structure uses elastic clips made of silicone to secure the cables of anesthesia machines, monitors, and other equipment using pre-deformation clamping force.
[0045] Folding operation: After disassembling the medicine placement tray 50, retract and reset the gas spring 21. Then pull the bolt 61 to unlock the positioning hole 63 of the limit plate 60. Rotate the gas spring 21 to make it contact the folding inclined support 13. Then press the limit pins 43 on both sides to make them disengage from the limit frame 44. The support rod 41 rotates around the third pivot 40 to fold. The folding inclined support 13 is simultaneously lowered around the first pivot 12, finally compressing the overall structure to the minimum volume.
[0046] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
