Description

Technical Field

[0001] The present invention relates to the technical field of infusion sets, and specifically to a roof-mounted infusion set used in a rescue vehicle. Background Art

[0002] When an ambulance transports patients, due to the inevitable vibrations and bumps during vehicle driving, the equipment and items in the vehicle often sway due to inertia, which has a great impact on the operation stability during first aid, especially for infusion treatment.

[0003] For temporary in-vehicle treatment, hooks are usually provided on the roof of the ambulance for hanging infusion bottles, which are connected to the patient's blood vessels through pipelines. However, during driving, the swaying of the infusion bottle will cause the infusion pipeline to swing, and may even cause the needle to fall off, affecting the infusion effect. In severe cases, it may also lead to dangerous situations such as the needle falling off from the puncture position and the infusion bottle breaking.

[0004] Currently, the design of existing roof-mounted infusion sets (such as Chinese Patent CN213789306U) does not fully consider the vibration factors during the driving of the ambulance, resulting in the infusion bottle being prone to collision or swaying, which has an adverse impact on the treatment of patients.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with 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.

[0022] Embodiment 1: Please refer to Figures 1-5 , a roof-mounted infusion device used in an emergency vehicle, including a main shaft 1 fixedly installed on the roof of the emergency vehicle. As Figure 1 shown, one end of a rotating plate 2 is rotatably installed on the main shaft 1 and can be pressed and locked by a pressing cap 3. The pressing cap 3 is screwed to the bottom end of the main shaft 1; As Figure 1 shown, a chute 4 is opened at the bottom of the other end of the rotating plate 2. A sliding plate 5 is slidably installed in the chute 4. In this embodiment, the sliding plate 5 is a T-shaped plate, and the chute 4 is a T-shaped groove matching the T-shaped plate. The T-shaped plate slides in the T-shaped groove, which can not only freely adjust the position but also prevent falling off.

[0023] As Figure 2 shown, a vertically integrated vertical cylinder 6 and a bottom cylinder 7 are fixedly installed at the bottom of the sliding plate 5, and an insertion port 8 is opened at the bottom end of the bottom cylinder 7. The infusion bottle is inserted into the vertical cylinder 6 and the bottom cylinder 7 from the insertion port 8; In order to fix the infusion bottle in the vertical cylinder 6 and the bottom cylinder 7, in this embodiment, a plurality of annularly arranged clamping blocks 12 are arranged around the insertion port 8. The clamping blocks 12 are slidably installed on the inner bottom wall of the bottom cylinder 7, and inclined slopes 13 are formed at the tops of the inner ends. The plurality of clamping blocks 12 can move synchronously, contracting or expanding annularly. In this way, after the infusion bottle is inserted into the bottom cylinder 7 and the vertical cylinder 6, by the mutual approach of the plurality of clamping blocks 12, blocking at the variable diameter of the infusion bottle mouth can effectively fix the position of the infusion bottle, effectively avoiding the problem of the infusion bottle shaking or falling off when the vehicle bumps; At the same time, this fixing method is applicable to infusion bottles of different sizes and different materials such as glass and plastic, and is not afraid of the deformation of the infusion bottle after infusion.

[0024] As Figure 3 and Figure 4 shown, a rotating ring 9 is rotatably installed in the bottom cylinder 7 through a bearing. A plurality of arc-shaped grooves 10 are evenly opened on the rotating ring 9. A sliding column 11 is slidably arranged in the arc-shaped grooves 10. The sliding column 11 is fixedly installed on the top of the clamping block 12. In addition, a central groove is also opened at the center of the rotating ring 9; The central groove facilitates the passage of the infusion bottle. When it is necessary to make several clamping blocks 12 contract or expand annularly, just control the rotation of the rotating ring 9. When the rotating ring 9 rotates, through the guidance of the arc-shaped groove 10 on the sliding column 11, the clamping blocks 12 can slide on the inner bottom wall of the bottom cylinder 7.

[0025] In this embodiment, a driving cylinder 14 is fixedly installed on the top of the rotating ring 9. The driving cylinder 14 is rotatably arranged in the vertical cylinder 6, and a worm gear 15 is provided on the outer wall of the top end. The outer wall of the worm gear 15 is engaged with a worm 16. The worm 16 is rotatably installed on a fixing plate 18 through a fixing shaft 17. The fixing plate 18 is fixedly installed on the outer wall of the vertical cylinder 6. Therefore, to control the rotation of the rotating ring 9, just rotate the worm 16. When the worm 16 rotates, it drives the worm gear 15 engaged with its outer wall to rotate. When the worm gear 15 rotates, the rotating ring 9 can be driven through the driving cylinder 14.

[0026] Embodiment Two: Please refer to Figure 3 and Figure 4 Based on Embodiment One, in this embodiment, a first gear 23 is rotatably installed on the inner top wall of the vertical cylinder 6. A friction pad 24 is provided at the bottom of the first gear 23. After the infusion bottle is inserted, its top end can be pressed tightly against the friction pad 24, so as to drive the first gear 23 to rotate. In the present invention, a transmission mechanism is provided between the first gear 23 and the fixing shaft 17. When the first gear 23 rotates, the fixing shaft 17 can be synchronously driven to rotate through the transmission mechanism, and then the worm 16 is driven to rotate. When the worm 16 rotates, the rotation of the rotating ring 9 is thus controlled.

[0027] The transmission mechanism specifically includes a second gear 22, a third gear 21, a driving wheel 20 and a driven wheel 19. As shown in Figure 3 and Figure 4 , the outer wall of the first gear 23 is engaged with the second gear 22. The outer wall of the second gear 22 is engaged with the third gear 21. The third gear 21 is rotatably installed on a top plate through a vertical shaft. The top plate is fixedly installed on the top of the fixing plate 18. The third gear 21 is coaxially (vertical shaft) installed with the driving wheel 20. The outer wall of the driving wheel 20 is engaged with the driven wheel 19. The driven wheel 19 is fixedly installed on the fixing shaft 17. In this embodiment, both the driving wheel 20 and the driven wheel 19 are bevel gears. Press the top end of the infusion bottle tightly against the friction pad 24. At this time, rotate the infusion bottle, and the first gear 23 can be rotated. The rotation of the first gear 23 drives the third gear 21 to rotate through the transmission of the second gear 22. The rotation of the third gear 21 drives the driving wheel 20 to rotate through the vertical shaft. The rotation of the driving wheel 20 drives the driven wheel 19 engaged with its outer wall to rotate. When the driven wheel 19 rotates, the worm 16 can be driven to rotate. When the worm 16 rotates, the rotating ring 9 can be driven to rotate through the transmission, and then the movement of the clamping blocks 12 is controlled. Thus, in the present invention, after the infusion bottle is inserted into the bottom cylinder 6 and the vertical cylinder 7, it is tightened against the friction pad 24 and rotated, so as to control the approaching of several clamping blocks 12. The operation is simple and the fixation is stable. The worm gear 15 and the worm 16 mechanism play a role of one-way transmission, enabling the friction pad 24 to actively drive the clamping blocks 12 to move, while the clamping blocks 12 cannot drive the friction pad 24 to rotate in the reverse direction.

[0028] Embodiment Three: Please refer to Figure 3 and Figure 6 , on the basis of Embodiment One or Embodiment Two, in this embodiment, airbag strips 28 that can be inflated and bulged are provided on both sides of the sliding plate 5; The rotating plate 2 can adjust its position by rotation, and the positions of the vertical cylinder 6 and the bottom cylinder 7 on the rotating plate 2 can be adjusted by sliding. After adjusting to a suitable position, control the airbag strips 28 to inflate and bulge, and by increasing the friction force, it can be avoided that the sliding plate 5 slides in the chute 4; Through this design, the positions of the vertical cylinder 6 and the bottom cylinder 7 can be freely adjusted within a circular range on the car roof, and the fixed position of the infusion bottle can be regulated according to needs.

[0029] Regarding the control of the inflation of the airbag strips 28, specifically, as Figure 6 shown, an inner cavity 25 is formed inside the sliding plate 5. The inner cavity 25 is connected to the airbag strips 28 through a pipeline. A piston 26 is movably arranged up and down inside the inner cavity 25. Controlling the piston 26 to move upward can fill the air in the inner cavity 25 into the airbag strips 28 through the pipeline. In this embodiment, a lead screw 27 is screwed to the bottom of the piston 26. The bottom end of the lead screw 27 extends into the vertical cylinder 6 and is fixedly connected to the second gear 22. In addition, a limit insertion rod is inserted at the bottom of the piston 26, and the limit insertion rod is fixedly installed on the inner bottom wall of the inner cavity 25; When the friction pad 24 is rotated by rotating the infusion bottle, the second gear 22 will also be rotated through transmission. The rotation of the second gear 22 drives the lead screw 27 to rotate, and the rotation of the lead screw 27 can drive the piston 26 to move upward, thereby synchronously fixing the position of the sliding plate 5 in the chute 4.

[0030] Embodiment Four: Please refer to Figure 4 and Figure 7 , on the basis of Embodiment One, Embodiment Two or Embodiment Three, in this embodiment, the driving cylinder 14 is fixedly installed on the top of the rotating ring 9 through several connecting columns 29. In addition, a fixed cabinet 30 is fixedly installed inside the inner sides of several sliding columns 11. An inner plate 31 is movably and telescopically arranged inside the fixed cabinet 30. The end of the inner plate 31 passes through the gap between two adjacent connecting columns 29. Specifically, as Figure 7 shown, a moving plug is fixedly installed at one end of the inner plate 31 located inside the fixed cabinet 30, and the moving plug is supported by a spring 32; When the clamping block 12 moves inwards to block at the reduced-diameter part of the infusion bottle mouth, the inner plate 31 will also abut against the body of the infusion bottle, and reversely compress the spring 32 following the moving distance of the sliding column 11. Through the abutment of the inner plate 31 against the body of the infusion bottle, the position of the infusion bottle can be further fixed to prevent the infusion bottle from shaking in the vertical cylinder 6.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
