Figures 1-5 The outer tube 4 is vertically arranged and has an internal accommodating space passing through from top to bottom. The top of the accommodating space is open, and the bottom is provided with a weighing sensor 6. The inner tube 2 is movably installed in the inner tube 4, and the top of the inner tube 2 extends out of the outer tube 4 and is provided with a hook structure. The electric drive structure 02 is used to drive the inner tube 2 to move up and down in the outer tube 4. The broadcast device 03 is used to broadcast voice. The control device 01 is electrically connected with the weighing sensor 6, the electric drive structure 02 and the broadcast device 03, and is used to receive signals from the weighing sensor 6 and control the electric drive structure 02 and the broadcast device 03. The electric appliance fixing inner shell 04 is fixedly installed in the inner tube 4, and is used to install the control device 01, the electric drive structure 02 and the broadcast device 03.

The electric lifting infusion rod can drive the inner tube 2 to move up and down by the electric drive structure 02, and then the height of the hooking structure for hanging the infusion equipment is adjusted, which is very convenient; when the liquid medicine is insufficient or the infusion is about to be completed, the control device 01 can control the broadcasting device 03 to play a prompt sound, so that the medical staff does not need to continuously monitor the infusion process, the workload is reduced, and the nursing risk of failing to timely change medicine or pull out the needle is reduced.

[0064] In the embodiment, the infusion equipment refers to an infusion bottle or an infusion bag connected with an infusion device.

[0065] As shown in Figure 2 The electric drive structure comprises a drive motor 11, a drive nut 13, a screw rod 14 and a limiting structure; the drive motor 11 is installed in the electric appliance fixed inner shell 04; the drive nut 13 is fixedly installed at the bottom of the inner tube 2 and has a through inner drive thread; one end of the screw rod 14 is fixedly connected with a drive shaft of the drive motor 11 and is arranged in the drive nut 13 and is threadedly connected with the drive nut 13; the limiting structure is used for limiting the inner tube 2 from rotating with the screw rod 14. The electric lifting infusion rod can be automatically lifted by the drive motor 11, manual adjustment is not needed, operation is easier, and convenience is better.

[0066] As shown in Figure 2 and Figure 5 The limiting structure comprises a limiting boss 23 and a limiting groove 24; the limiting boss 23 is formed on the outer wall of the drive nut 13 and has at least two oppositely arranged first limiting surfaces; the limiting groove 24 is formed on the inner wall of the outer tube 4 in the axial direction and has a second limiting surface which is slidably connected with the two first limiting surfaces of the limiting boss 23. When the drive nut 13 fixedly installed on the inner tube 4 tries to rotate relative to the outer tube 4 due to the driving of the screw rod 14, the inner tube 2 cannot rotate due to the limiting action of the limiting boss 23 and the limiting groove 24 and can only move up and down in the axial direction, so that the height of the inner tube 2 is adjusted up and down.

[0067] As shown in Figure 3As shown, the top opening position of the outer tube 4 is provided with an outer tube front cover 3, the inner diameter of the hollow inner cavity of the outer tube front cover 3 is basically the same as the outer diameter of the inner tube 2, which is used for guiding the up and down movement of the inner tube 2.

The outer tube front cover 3 is usually connected with the outer tube 4 by threads, buckles or other fixing methods, which ensures that the inner tube 2 can stably pass through the outer tube 4 during telescoping and will not be separated or shaken due to external force. The outer tube front cover 3 also plays a guiding role when the telescopic rod is working, ensuring that the inner tube 2 maintains straight-line movement during telescoping.

[0068] The tail end opening position of the outer tube 4 is provided with an outer tube rear cover 5, and the weighing sensor 6 is fixedly installed below the outer tube rear cover 5.

The close buckling of the upper shell 16 and the lower shell 17 forms a stable structure, so that the internal electronic components of the infusion rod are more stable during use and are not easy to shake or fall, which can provide firm protection for the electronic components and prevent them from being damaged due to external impact.

[0072] As preferred, a mounting threaded hole is formed on the upper shell 16 or the lower shell 17, and a mounting through hole is formed on the outer tube 4 opposite to the mounting threaded hole, and a mounting screw is used to pass through the mounting through hole and be screwed with the mounting threaded hole, so as to fix the electric appliance fixing inner shell 04 inside the outer tube 4.

[0073] In the embodiment, the control device 01 comprises a control circuit board 15 and control buttons 9; the control circuit board 15 is arranged inside the electric appliance fixing inner shell 04; the control buttons 9 are opposite to the control circuit board 15 and respectively extend outward from a plurality of through holes formed on the electric appliance fixing inner shell 04 and the outer tube 4 to a certain length for operation; the control buttons 9 comprise an up button 091, a down button 092, a clear button 093 and a stop button 094.

[0074] When the up button 091 is continuously triggered, the control circuit board 15 controls the electric drive structure 02 to rotate forward to drive the inner tube 2 to move upward relative to the outer tube 4; when the triggering is stopped, the control circuit board 15 controls the electric drive structure 02 to stop; when the down button 092 is continuously triggered, the control circuit board 15 controls the electric drive structure 02 to rotate reversely to drive the inner tube 2 to move downward relative to the outer tube 4; when the triggering is stopped, the control circuit board 15 controls the electric drive structure 02 to stop.

[0075] After the empty infusion device is hooked on the hook structure, the clear button 093 is pressed, and the control circuit board 15 records the weight signal transmitted by the current weighing sensor 6 as zero; when the weight signal transmitted by the weighing sensor 6 to the control circuit board 15 reaches a first set weight, the control circuit board 15 controls the loudspeaker 18 to emit a first prompt sound; the stop button 094 is triggered, and the loudspeaker 18 stops emitting sound; when the weight signal transmitted by the weighing sensor 6 to the control circuit board 15 reaches a second set weight, the control circuit board 15 controls the loudspeaker 18 to emit a second prompt sound; the stop button 094 is triggered, and the loudspeaker 18 stops emitting sound; the first set weight is greater than the second set weight.

[0076] The medical staff can control the start and stop of the electric drive structure 02 and the operation of the broadcast device through the control device, which is simple and intuitive, and can be easily controlled by directly pressing the control button 9.

[0077] In the embodiment, the control circuit board 15 is provided with an electric quantity indicator lamp 8; the electric quantity indicator lamp 8 can intuitively display the battery power state of the device to the user through different colors or flashing modes. This design helps the user to understand the remaining use time of the device, so as to charge in time when the power is insufficient, avoiding the device shutdown or function limitation due to power consumption.

[0078] The use method of the electric lifting infusion rod with the broadcasting function in the embodiment is as follows:

[0079] Firstly, whether the height of the current infusion rod meets the use requirement is observed, if the height of the infusion rod is low, the control circuit board 15 controls the electric drive structure 02 to rotate forward when the rising button 091 is continuously triggered, and the inner tube 2 moves upward relative to the outer tube 4; the height of the hook 1 structure on the inner tube 2 is adjusted to the appropriate position;

[0080] Then, the empty infusion equipment is hung on the hook 1, the zero button 093 on the control button 9 is pressed, the control circuit board 15 records the weight signal transmitted by the current weighing sensor 6 as zero, and the empty infusion equipment is removed; the new infusion equipment to be infused is hung on the hook structure at the end of the inner tube, and the patient is normally infused;

[0081] When the weight of the infusion equipment decreases to the first set weight (such as 50 grams), the weighing sensor 6 sends a first signal to the control circuit board 15, and the control circuit board 15 controls the loudspeaker 18 to emit a first prompt sound after receiving the first signal, reminding the medical staff that the infusion is about to be completed; the medical staff presses the stop button 094, and the loudspeaker 18 stops emitting sound;

[0082] When the weight of the infusion equipment decreases to the second set weight (such as 10 grams), it represents that the infusion is completed, the weighing sensor 6 sends a second signal to the control circuit board 15, and the control circuit board 15 controls the loudspeaker 18 to emit a second prompt sound after receiving the second signal, reminding the medical staff to change the medicine or pull out the needle; the medical staff presses the stop button 094 again, and the loudspeaker 18 stops emitting sound.

[0083] Obviously, the above embodiment is only an example for clear illustration, and does not limit the implementation. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the implementation modes do not need to be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present technical solution.
