[0023] Embodiment 1

[0024] like Figure 1 As shown, an empty bottle alarm infusion stand includes a rod body 1, a hook 2, an alarm 3, and a heater 4. A longitudinal slide groove 5 is provided on the upper part of the rod body 1. A positioning block 6 is slidably connected in the longitudinal slide groove 5. A plurality of threaded holes 18 are evenly opened in the longitudinal direction of the side wall of the longitudinal slide groove 5. A screw 19 passes through the threaded hole 18 and presses against the positioning block 6 to fix the positioning block 6. A hole that passes through the upper and lower parts is opened on the positioning block 6. A control rod 7 is inserted into the hole. The upper end of the control rod 7 is connected to the hook 2. A spring 8 is sleeved on the rod body of the control rod 7 between the hook 2 and the positioning block 6. An alarm switch 9 is provided on the top of the longitudinal slide groove 5, and a heating switch 10 is provided on the bottom. The alarm 3 is arranged at the top of the rod body 1 and is electrically connected to the alarm switch 9. The heater 4 is arranged below the longitudinal slide groove 5 and is electrically connected to the heating switch 10. The heater 4 is externally connected to a heating clip 12, and the heating clip 12 is clamped on the infusion tube 13. During infusion, the hanging bottle 20 filled with liquid is hung on the hook 2, and the gravity of the hanging bottle 20 is used to drive the control rod 7 to move downward, the spring 8 is compressed, and the lower end of the control rod 7 contacts and presses the heating switch 10, starting the heater 4, clamping the heating clamp 12 on the infusion tube 13 to heat the liquid; as time goes by, the weight of the hanging bottle 20 gradually becomes lighter, and the spring 8 slowly releases its elastic force, pushing the control rod 7 and the hook 2 upward. When the bottle is empty or about to be empty, the upper end of the control rod 7 contacts and presses the alarm switch 9, starting the alarm, reminding the medical staff that the infusion is completed and to remove the needle in time; the alarm switch 9 is a touch switch, which is turned on by lightly touching the switch and disconnected by releasing it, and the heating switch 10 is a push switch, which is turned on by pressing it and can be disconnected by pressing it again.

[0025] Since the control rod 7 gradually moves upward after pressing the heating switch 10, the heating switch 10 is in the on state for a long time, so the heating disconnect device is designed to trigger to realize the power off of the heater 4 and stop heating. The heating disconnect device is arranged on the rod body 1, below the positioning block 6, and the heating disconnect device includes a straight-line flap 14, a pressure rod 15, and a power-off switch 16. The middle part of the straight-line flap 14 is pivoted on the rod body 1, one end is located in the longitudinal slide groove 5, and the other end is located outside the rod body 1. The top of the outer end of the straight-line flap 14 is connected to the spring 2 17 and the fixed block 11 in sequence, and the bottom is connected to the pressure rod 15. The fixed block 18 is fixed to the rod body 1, and the lower end of the pressure rod 15 abuts against the power-off switch 16. The power-off switch 16 is fixed to the rod body 1, and the power-off switch 16 is electrically connected to the heater 4. Preferably, the lower end of the control rod 7 is conical. When the straight flap 14 is horizontal, its inner end is interference fit with the control rod 7. When the control rod 7 moves down, the lower end contacts the inner end of the straight flap 14, driving it to rotate downward. According to the lever principle, the outer end of the straight flap 14 rotates upward, compressing the spring 2 17, and lifting the pressure rod 15 at the same time, and the power-off switch 16 is in a disconnected state. When the control rod 7 gradually moves up to separate from the straight flap 14, the spring 2 17 pushes the straight flap 14 to return to its original state, and the pressure rod 15 presses the power-off switch 16 downward to turn it on, thereby realizing the power off of the heater 4 and stopping heating. The height of the positioning block 6 affects the upward travel of the control rod 7. The height of the positioning block 6 can be adjusted according to the weight of the hanging bottle 20 to ensure that the control rod 7 can contact the alarm switch 9 during the upward movement. The upward travel of the control rod 7 is greater than the vertical distance between the straight flap 14 and the heating switch 10, ensuring that the heating is stopped first and then the alarm is sounded.

[0026] Preferably, in order to ensure that the hanging bottle 20 moves upward smoothly with the control rod, the hook 2 is slidably connected to the longitudinal slide groove 5.

[0027] Embodiment 2

[0028] The difference between the second embodiment and the first embodiment is that the fixing method of the positioning block 6 is different. Figure 2 As shown, the positioning block 6 is sleeved on the longitudinal slide groove 5 and is provided with a threaded hole, and the screw 19 passes through the threaded hole to tighten the rod body 1.

[0029] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
