It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0025] Reference Figures 1-11 An emergency infusion device includes a support rod 1 and a telescopic rod 2, which are connected by bolts. A pin 3 is fixedly connected to the top of the telescopic rod 2, and a placement block 4 is attached to the top of the telescopic rod 2. The outer wall of the pin 3 is attached to the inner wall of the placement block 4. The placement block 4 has symmetrically arranged ordinary chambers 5 and heating chambers 6. A push plate 7 is slidably connected inside the placement block 4, and a push block 8 is fixedly connected to the bottom of the push plate 7, thus fixing the push block 8. The outer wall of the push block 8 is slidably connected inside the placement block 4. A first rotating shaft 9 is rotatably connected inside the push block 8, and a rotating plate 10 is fixedly connected to the outer wall of the first rotating shaft 9. The rotating plate 10 is internally fixedly connected to a second rotating shaft 11. The rotating plate 10 serves to connect the first rotating shaft 9 and the second rotating shaft 11. Pull blocks 12 are rotatably connected to both ends of the second rotating shaft 11. A first spring 13 is provided between the pull block 12 and the placement block 4. A pull plate 14 is fixedly connected to the outer wall of the pull block 12. The outer wall of the pull plate 14 is slidably connected to the inside of the placement block 4. A plug rod 15 is fixedly connected to the outer wall of the pull plate 14. The outer wall of the plug rod 15 is slidably connected to the inside of the placement block 4. The outer wall of the plug rod 15 abuts against the inside of the plug post 3. A connecting plate 16 is fixedly connected to the bottom of the pull plate 14. A fixing mechanism 17 is provided on the lower surface of the connecting plate 16.
[0026] The usage process of the emergency infusion device provided by this invention is as follows: The support rod 1 and telescopic rod 2 are designed to be telescopic and adjustable. The position between the support rod 1 and telescopic rod 2 can be adjusted using bolts to adjust the overall height of the device. The placement block 4 has two chambers: a standard chamber 5 and a heating chamber 6 on the opposite side for heating the liquid in the infusion bottle 19. The heating chamber 6 and the standard chamber 5 have the same internal structure, the only difference being that the heating chamber 6 contains an electric heating plate for heating the liquid. The heating chamber 6 and the standard chamber 5 can be selected in different positions according to different infusion needs. When switching between the two positions is required, the push plate 7 is pushed, causing the push block 8 to slide inside the placement block 4. During the sliding process, the push block 8 drives the internal first rotating shaft 9 to slide down synchronously. The rotating plate 10 is connected to the push block 8 via the first rotating shaft 9, allowing the rotating plate 10 to rotate via the sliding of the first rotating shaft 9. During the rotation, the rotating plate 10 pulls the pull block 12 and the pull plate 14 to slide synchronously via the internal second rotating shaft 11. During the process, the first spring 13 is compressed, and the sliding of the pull plate 14 will drive the insertion rod 15 on one side to slide. The insertion rod 15 plays the role of restricting the placement block 4 and the insertion post 3. By sliding the insertion rod 15 into or out of the insertion post 3, the position of the placement block 4 can be fixed or adjusted. When the insertion rod 15 slides out of the insertion post 3, the placement block 4 can be rotated. When the insertion rod 15 rotates to the position of the insertion post 3 on the other side, the rebound action of the first spring 13 can push the insertion rod 15 in the opposite direction to insert it into the insertion post 3, fixing the placement block 4. During the sliding of the pull plate 14, the fixing mechanism 17 will also slide synchronously through the connecting plate 16, so as to release the infusion bottle 19 when adjusting the placement block 4 and fix the infusion bottle 19 when fixing it. Without moving the whole device, different chambers can be quickly switched according to different emergency situations to adapt to different infusion needs. During the switching process, the infusion bottle 19 can be fixed or released at the same time, reducing the time for medical staff to manually adjust the infusion bottle 19 and improving the quality and efficiency of emergency treatment.
[0027] Reference Figures 3-5The fixing mechanism 17 includes an adjusting plate 1701, the upper surface of which is fixedly connected to the lower surface of a connecting plate 16. The connecting plate 16 connects the adjusting plate 1701 and the pull plate 14. The outer wall of the adjusting plate 1701 is slidably connected to the interior of the placement block 4. A second spring 1702 is fixedly connected to the inner wall of the adjusting plate 1701. A first locking plate 1703 is fixedly connected to the outer wall of the second spring 1702. A limit post 1704 is fixedly connected to the outer wall of the first locking plate 1703. Spring 1702 is sleeved on the outer wall of limiting post 1704. Limiting strips 1705 are slidably connected inside the adjusting plate 1701 and the first clamping plate 1703. The outer wall of the limiting strip 1705 is fixedly connected to the inner wall of the placement block 4. The limiting strip 1705 is fixed to the inner wall of the placement block 4 to limit the adjusting plate 1701 and the first clamping plate 1703 and prevent displacement during sliding. A second clamping plate 18 is fixedly connected inside the placement block 4. A buffer mechanism 37 is provided at the bottom of the support rod 1.
[0028] The usage process of the emergency infusion device provided by this invention is as follows: During the sliding of the pull plate 14, the connecting plate 16 at the bottom will also slide synchronously inside the placement block 4, allowing the fixing mechanism 17 on the lower surface of the connecting plate 16 to slide accordingly, releasing the limiting fixation of the infusion bottle 19. During the sliding of the connecting plate 16, the adjusting plate 1701 will slide, and the adjusting plate 1701 will pull the first locking plate 1703 to slide through the connection of the second spring 1702, causing the first locking plate 1703 to disengage from the infusion bottle 19. This allows for the simultaneous fixing or removal of the infusion bottle 19 during the switching between the ordinary chamber 5 and the heating chamber 6. Furthermore, the design of the second spring 1702 allows for the adjustment of different sized infusion bottles 19. When the infusion bottle 19 is positioned between the first clamping plate 1703 and the second clamping plate 18, it will press the first clamping plate 1703 on one side, causing it to press the second spring 1702. When the second spring 1702 is compressed, it will generate a reaction force on the infusion bottle 19. This reaction force is equal in magnitude and opposite in direction to the applied force. When this reaction force and the applied force reach equilibrium, the infusion bottle 19 will be fixed in a specific position. This fixes the infusion bottle 19, adapts to different sizes of infusion bottles 19, and fixes them to prevent the infusion bottle 19 from accidentally tipping over or breaking during use, reducing the risk of accidental detachment.
[0029] Reference Figure 3 , Figures 6-10An infusion bottle 19 is attached between the second clamping plate 18 and the first clamping plate 1703, which can fix the infusion bottle 19. A needle 21 is provided inside the infusion bottle 19. An adjustment cavity 22 is fixedly connected to the lower surface of the needle 21, and the adjustment cavity 22 serves to fix the needle 21. An infusion tube 20 is fixedly connected to the bottom of the adjustment cavity 22. A rotating rod 23 is rotatably connected inside the adjustment cavity 22. A knob 27 is fixedly connected to one end of the rotating rod 23. An adjustment plate 24 is fixedly connected to the outer wall of the rotating rod 23, and the outer wall of the adjustment plate 24 fits against the inner wall of the adjustment cavity 22. A fixing post 25 is fixedly connected to the outer wall of the adjustment cavity 22. Multiple slots 26 are opened inside the fixing post 25. The outer wall of the rotating rod 23 is rotatably connected to the inside of the fixing post 25, and a ball bearing 28 is slidably connected inside the rotating rod 23. The outer wall of the ball bearing 28 abuts against the inner wall of the slot 26; a connecting piece 29 is fixedly connected to the outer wall of the ball bearing 28, and the outer wall of the connecting piece 29 is slidably connected to the inside of the rotating rod 23; a third spring 30 is fixedly connected to the outer wall of the connecting piece 29, and the outer wall of the third spring 30 is fixedly connected to the inside of the rotating rod 23; a ratchet 31 is fixedly connected to the outer wall of the rotating rod 23, and a pawl 32 is meshed with the tooth end of the ratchet 31; a fixed shaft 33 is fixedly connected to the inside of the pawl 32, and both ends of the fixed shaft 33 are rotatably connected to the inside of the fixed post 25; the fixed shaft 33 rotates inside the fixed post 25 to provide stable support for the pawl 32; a pressure plate 34 is fixedly connected to the outer wall of the pawl 32, a spring 35 is fixedly connected to the bottom of the pressure plate 34, a support plate 36 is fixedly connected to the bottom of the spring 35, and the outer wall of the support plate 36 is fixedly connected to the outer wall of the fixed post 25.
[0030] The usage process of the emergency infusion device provided by this invention is as follows: When intravenous infusion is needed, insert the needle 21 into the bottom of the infusion bottle 19. The liquid will flow through the needle 21 into the regulating chamber 22 and then into the infusion tube 20. The regulating chamber 22 has an observation window to observe the liquid and the position of the regulating plate 24 inside. The liquid flow rate can be controlled by adjusting the angle of the regulating plate 24 inside the regulating chamber 22. Rotating the knob 27 causes the rotating rod 23 and the regulating plate 24 to rotate synchronously inside the regulating chamber 22. When the rotating rod 23 rotates, the squeezing force between it and the fixed post 25 causes the ball bearing 28 to slide inside the rotating rod 23, which pushes the connecting plate 29 to slide synchronously inside the rotating rod 23. During the sliding process, the third spring 30 is squeezed. The fixed post 25 has multiple slots 26 that can engage with the ball bearing 28. During the rotation of the rotating rod 23, the ball bearing 28 will be engaged in different slots 26. The position of the slots 26 is designed in a regular pattern. Each time the ball bearing 28 slides into the slot 26, the angle is different. Similarly, this allows for more precise position adjustments, thereby limiting and fixing the positions of the rotating rod 23 and the adjusting plate 24 after rotation. When the rotating rod 23 rotates, it also drives the ratchet 31 on the outer wall to rotate synchronously. During the rotation of the ratchet 31, it pushes the pawl 32 at the tooth end, causing it to drive the fixed shaft 33 to rotate simultaneously. The meshing between the ratchet 31 and the pawl 32 can limit the rotation of the rotating rod 23, preventing it from reversing and ensuring the stability of the adjusted plate 24 position. When it is necessary to rotate the rotating rod 23 in the opposite direction, press the pressure plate 34 to drive the pawl 32 to rotate and squeeze the spring 35, releasing the restriction on the ratchet 31. This allows the rotating rod 23 and the adjusting plate 24 to rotate in the opposite direction. The cross-sectional area of the rotating plate 24 forms a more linear relationship with the rotation angle, allowing medical staff to more intuitively and precisely fine-tune the fluid flow rate. The locking of the ratchet 31 and the pawl 32 fixes the adjusting plate 24 at a certain angle, providing a more stable and continuous flow rate, while meeting the needs of rapid response in emergency situations.
[0031] Reference Figure 1 and Figure 11 The buffer mechanism 37 includes a support plate 3701, the upper surface of which is fixedly connected to the bottom of the support rod 1. The support plate 3701 provides support and fixation for the support rod 1. A connecting column 3702 is fixedly connected inside the support plate 3701, which also provides fixation for the connecting column 3702. A buffer column 3703 is slidably connected inside the connecting column 3702. A buffer spring 3704 is fixedly connected to the top of the buffer column 3703. The outer wall of the buffer spring 3704 is fixedly connected to the inside of the connecting column 3702. A caster wheel 3705 is fixedly connected to the bottom of the buffer column 3703.
[0032] The usage process of the emergency infusion device provided by this invention is as follows: The bottom of the tray 3701 is equipped with casters 3705 that allow the entire device to move. The casters 3705 facilitate the movement of the entire device to a suitable position and then fix it in place. During the movement of the casters 3705, the buffer column 3703 will be pushed to slide inside the connecting column 3702. A buffer spring 3704 is provided between the top of the buffer column 3703 and the connecting column 3702. The buffer spring 3704 can absorb the bumps during the movement, reduce the instability and shaking of the infusion device when it is moved, thereby improving the overall stability.
