DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: an infusion cut-off device based on gravity detection, including a support column 1 as the core bracket of the entire device. Inside the top end of the support column 1, a lever 2 is rotatably connected. On both the left and right sides of the lever 2, expansion blocks 3 are fixedly connected. At the bottom end of the right expansion block 3, a hook 4 is fixedly connected to connect subsequent components. Inside the hook 4, a lead block 5 is detachably connected to provide gravity. Outside the support column 1, an engagement component is fixedly connected to provide subsequent engagement, connecting subsequent components. The engagement component includes an engagement column 6, the inside of the engagement column 6 is fixedly connected to the outside of the support column 1, an engagement plate 7 is fixedly connected to the outside of the engagement column 6, a receiving hole 8 is opened inside the engagement plate 7. The outer parts of two sliding rods 9 are respectively slidably connected to the front and rear sides inside the two engagement plates 7. Inside the engagement component, a receiving hole 8 is opened, and the front and rear sides inside the engagement component are both slidably connected with sliding rods 9. A first strong spring 10 is sleeved on the outside of the sliding rod 9 to provide a clamping force. One end of the first strong spring 10 is fixedly connected to one side inside the receiving hole 8. On the far sides of the two sliding rods 9, a pull plate 11 is fixedly connected for easy manual operation. One side of the pull plate 11 is in contact with one side of the engagement plate 7. On the close sides of the two sliding rods 9, a clamping block 12 is fixedly connected. The other end of the first strong spring 10 is fixedly connected to one side of the clamping block 12. One side of the clamping block 12 is in contact with one side inside the receiving hole 8. Inside the front clamping block 12, a sensing plate 13 is provided to sense the position change of the infusion bottle 15. Inside the bottom end of the left expansion block 3, a connection block 14 is slidably connected. Inside the bottom end of the connection block 14, an infusion bottle 15 is rotatably connected to support the infusion bottle 15. On the close sides of the two sensing plates 13, they are in contact with the outside of the infusion bottle 15. At the bottom end of the infusion bottle 15, an infusion tube is fixedly connected to transport the medicinal liquid into the patient's body;

[0031] Through the combination of the lever principle and gravity detection, the above structure ensures the safety and accuracy during the infusion process. When the liquid in the infusion bottle 15 decreases to a certain extent, the lever 2 displaces due to the lead block 5 being heavier than the empty bottle, triggering the cut-off mechanism. The clamping block 12 clamps the infusion tube to stop the infusion. At the same time, the sensing plate 13 will sense this change and remind the medical staff to replace the infusion bottle 15 by means of a sound, etc. This design reduces the need for manual monitoring, improving the degree of automation and medical safety.

[0032] Refer to Figure 1 and Figure 3, a pull rod 16 is slidably connected to the front inner wall of the left expansion block 3. One side of the pull rod 16 is engaged with the front inner part of the connection block 14. A second strong spring 17 is sleeved on the outer part of the pull rod 16 to provide the elastic force required for the pull rod 16 to return to its original position. A retaining disk 18 is fixedly connected to the outer part of the pull rod 16. A chamber 19 is formed inside the front end of the left expansion block 3. The outer part of the retaining disk 18 is slidably connected inside the chamber 19 to provide a sliding space for the retaining disk 18. One end of the second strong spring 17 is fixedly connected to one side of the retaining disk 18, and the other end of the second strong spring 17 is fixedly connected to one side inside the chamber 19. This setting can ensure that the retaining disk 18 and the pull rod 16 can stably remain in their original positions when not subjected to external forces. The front end of the pull rod 16 is fixedly connected to a driving disk 20 for medical staff to operate to initiate the process of replacing the infusion bottle 15.

[0033] With the above structure, when it is necessary to replace the infusion bottle 15, medical staff can operate the driving disk 20 to drive the connection block 14 to separate from the infusion bottle 15 via the pull rod 16. At this time, the second strong spring 17 is compressed and provides the necessary force to help the retaining disk 18 and the pull rod 16 return to their original positions. This design simplifies the rapid replacement process of the infusion bottle 15 and ensures the stability and reliability of the whole process.

[0034] Working principle: First, pull the pull plate 11. Then, under the pull of the pull plate 11, drive the sliding rod 9 to slide. Then, under the movement of the sliding rod 9, drive the clamping block 12 and the sensing plate 13 to move. Then, apply force to the first strong spring 10. Then, install the infusion bottle 15 on the adjacent side of the two clamping blocks 12. The force received by the first strong spring 10 will generate a return force, and this return force is the force to provide for clamping the clamping block 12. The design of the lead block 5 is lighter than a full infusion bottle 15 and heavier than an infusion bottle 15 that is almost empty. Then, when the infusion bottle 15 is almost empty, due to the gravity of the lead block 5, the lever principle is generated on the lever 2, and then the infusion bottle 15 is lifted. This will cause the bottom end of the clamping block 12 to clamp the infusion tube. Because there is no limit of the infusion bottle 15, the bottom ends of the two clamping blocks 12 approach each other. When the infusion bottle 15 is lifted, it will slide out from one side of the sensing plate 13 and not contact the sensing plate 13, and then make a sound to remind medical staff to replace the infusion bottle 15. When replacing the infusion bottle 15, first pull the driving disk 20. Under the pull of the driving disk 20, drive the pull rod 16 to separate from the inside of the connection block 14. Then, the connection block 14 can be driven to take out the infusion bottle 15 for rapid replacement. Under the movement of the pull rod 16, it also drives the retaining disk 18 to apply force to the second strong spring 17. Then, this will generate a return force, and this return force is the force to provide for fixing the connection block 14.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
