[0019] The beneficial effects of an infusion stand for clinical medicine provided by the present invention include:

[0020] 1. By setting up the hanging bottle mechanism, as the medicine in the medicine bottle decreases and the weight of the medicine bottle reduces, under the action of the gravity of the counterweight, the driving plug rod moves downward. Until the medicine in the medicine bottle is completely infused, the second toothed plate drops to the lowest point, and the first contact point contacts the second contact point, causing the sound and light alarm to emit sound and light alarms to notify the medical staff to come and change the medicine, which is convenient to use. At the same time, the wedge-shaped part of the plug rod drives the wedge block to move outward, driving the blocking block to squeeze the infusion tube, causing the infusion tube to bend, and the liquid medicine in the infusion tube stops flowing, preventing air from entering the infusion tube.

[0021] 2. By setting up the medicine-changing mechanism, then insert the limiting ring into the limiting frame, and push up the handle to insert the infusion puncture needle into the medicine bottle. When it is necessary to change the medicine bottle, pull down the connecting plate by the handle to pull out the infusion puncture needle from the medicine bottle. At the same time, drive the piston to move downward to draw the disinfection alcohol into the injection cylinder. Then replace the new medicine bottle and push up the handle to insert the infusion puncture needle into the new medicine bottle. During this process, drive the piston to move upward synchronously to inject the alcohol in the injection cylinder into the spray pipe and spray it out from the atomizing spray holes onto the surface of the infusion puncture needle to disinfect its surface and prevent bacterial infection in the air.

[0022] 3. By setting up the positioning mechanism, rotate the rotating handle to make the rotating handle in a vertical state. At this time, the first channel is communicated with the second channel, and press down the rotating handle to drive the positioning rod and the suction cup to move downward synchronously until the suction cup adsorbs on the ground. Then rotate the rotating handle in the opposite direction to make the rotating handle in a horizontal state. At this time, the first channel and the second channel are misaligned, maintaining the negative pressure state of the suction cup to fix the base on the ground and ensure the stability of the stand. And when the rotating handle is in a horizontal state, the long axis end of the positioning block closely adheres to the inner wall of the positioning groove to prevent the positioning rod from moving upward.

Detailed implementation manners

[0034] To make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Refer to Figures 1-9As shown in the figure, the present invention provides a technical solution: an infusion stand for clinical medicine, which includes a base 1, a sleeve rod 2 and a medicine bottle suspension mechanism 7. The sleeve rod 2 is installed on the surface of the base 1. A telescopic rod 3 is slidably inserted into the inner cavity of the sleeve rod 2. A plurality of support rods 4 are installed on the side wall of the base 1. One end of the support rod 4 is rotatably installed with a universal wheel 5 to facilitate the movement of the stand. A locking bolt 6 is threadedly connected to the surface of the sleeve rod 2 for fixing the telescopic rod 3 to facilitate the adjustment of the length of the telescopic rod 3. The medicine bottle suspension mechanism 7 is installed on the surface of the telescopic rod 3 for hanging the medicine bottle 10. The medicine bottle suspension mechanism 7 includes a support block 701, a connecting block 703 and a second toothed plate 708. The support block 701 is fixedly installed on the surface of the telescopic rod 3. A suspension 702 is slidably installed on the side wall of the support block 701. The medicine bottle 10 is placed in the inner cavity of the suspension 702. The connecting block 703 is fixedly installed on the side wall of the suspension 702. A slider 704 is fixedly installed on the side wall of the connecting block 703. A chute 705 is opened in the inner cavity of the support block 701.

[0036] Referring to Figure 1 - Figure 4, in a preferred embodiment, a first toothed plate 706 is fixedly installed on the side wall of the connecting block 703. The second toothed plate 708 is slidably installed in the inner cavity of the connecting block 703. A gear 707 is rotatably installed in the inner cavity of the support block 701. Both the second toothed plate 708 and the first toothed plate 706 are engaged with the gear 707. When the medicine bottle 10 to be infused is placed in the suspension 702, under the action of the gravity of the medicine bottle 10, the suspension 702 and the first toothed plate 706 are driven to move downward, and the second toothed plate 708 is driven to move upward in the opposite direction through the gear 707. A support rod 709 is fixedly installed on the surface of the second toothed plate 708. An acoustic-optic alarm 710 is installed on the surface of the support rod 709 for emitting an alarm. A hanging rod 711 is fixedly installed on the side wall of the support rod 709. A counterweight 712 is hung on the surface of the hanging rod 711. During use, different specifications of counterweights 712 can be selected according to the empty bottle mass of different medicine bottles 10. An insertion rod 713 is fixedly installed at the bottom of the second toothed plate 708. A first contact 714 is fixedly installed on the surface of the insertion rod 713. A second contact 715 is fixedly installed in the inner cavity of the support block 701 for controlling the on-off of the acoustic-optic alarm 710. As the medicine in the medicine bottle 10 decreases, the weight of the medicine bottle 10 decreases. Under the action of the gravity of the counterweight 712, the second toothed plate 708 is driven to move downward, driving the insertion rod 713 to move downward synchronously. Until the medicine in the medicine bottle 10 is completely infused, the second toothed plate 708 drops to the lowest point, and the first contact 714 contacts the second contact 715, causing the acoustic-optic alarm 710 to emit an acoustic-optic alarm to notify the medical staff to come and change the medicine, which is convenient to use.

[0037] Referring to Figures 1-4As shown, in a preferred embodiment, limiting rings 716 are symmetrically and fixedly installed on the side wall of the telescopic rod 3.

One end of the first spring 720 is fixedly connected to the telescopic rod 3, and the other end of the first spring 720 is fixedly connected to the wedge block 717 and is used to drive the wedge block 717 to move towards the insertion rod 713. As the second toothed plate 708 descends, it drives the insertion rod 713 to descend synchronously until when the first contact 714 contacts the second contact 715, the wedge-shaped part of the insertion rod 713 drives the wedge block 717 to move outwards, driving the blocking block 719 to squeeze the infusion tube 11, causing the infusion tube 11 to bend, and the liquid medicine in the infusion tube 11 stops flowing, preventing air from entering the infusion tube 11.

[0038] In a preferred embodiment, during use, under the gravitational force of the medicine bottle 10, it drives the suspension 702 and the first toothed plate 706 to move downwards, and drives the second toothed plate 708 to move upwards in the opposite direction through the gear 707. As the medicine in the medicine bottle 10 decreases, the weight of the medicine bottle 10 reduces. Under the gravitational force of the counterweight 712, it drives the second toothed plate 708 to move downwards, driving the insertion rod 713 to move downwards synchronously until when the medicine in the medicine bottle 10 is completely infused, the second toothed plate 708 drops to the lowest point, and the first contact 714 contacts the second contact 715, causing the sound and light alarm 710 to emit a sound and light alarm to notify the medical staff to come and change the medicine, which is convenient for use; as the second toothed plate 708 descends, it drives the insertion rod 713 to descend synchronously until when the first contact 714 contacts the second contact 715, the wedge-shaped part of the insertion rod 713 drives the wedge block 717 to move outwards, driving the blocking block 719 to squeeze the infusion tube 11, causing the infusion tube 11 to bend, and the liquid medicine in the infusion tube 11 stops flowing, preventing air from entering the infusion tube 11.

[0039] Refer to Figures 1-7 As shown, in a preferred embodiment, a medicine-changing mechanism 8 is installed on the surface of the suspension 702 for replacing the medicine bottle 10. The medicine-changing mechanism 8 includes a mounting plate 801, a connecting plate 802, and a limiting frame 804. The mounting plate 801 is fixedly installed on the side wall of the suspension 702. The connecting plate 802 is slidably installed on the side wall of the mounting plate 801. A handle 803 is fixedly installed at the bottom of the connecting plate 802. One end of the connecting plate 802 is installed with a limiting frame 804. One end of the infusion tube 11 is installed with a limiting ring 1101. An infusion puncture needle 1102 is installed on the surface of the limiting ring 1101 for inserting into the medicine bottle 10. The limiting ring 1101 is clamped in the inner cavity of the limiting frame 804.

After the medicine bottle 10 to be infused is placed in the suspension bracket 702, then the limit ring 1101 is inserted into the limit frame 804, and under the action of the positioning convex block 806, the limit ring 1101 is fixed in the inner cavity of the limit frame 804. At this time, the infusion puncture needle 1102 is located directly below the medicine bottle 10, so the infusion puncture needle 1102 can be inserted into the medicine bottle 10 by pushing up the handle 803. And during the subsequent process of replacing the medicine bottle 10, there is no need to directly touch the infusion puncture needle 1102 by hand, avoiding cross-infection.

Atomizing spray holes are formed on the surface of the spray pipe 814 for disinfecting the infusion puncture needle 1102. When it is necessary to replace the medicine bottle 10, by pulling the connecting plate 802 downward through the handle 803, the infusion puncture needle 1102 can be pulled out of the medicine bottle 10. At the same time, the piston 810 is driven to move downward, and the disinfection alcohol is pumped into the liquid injection cylinder 809. Then a new medicine bottle 10 is replaced, and the handle 803 is pushed upward to insert the infusion puncture needle 1102 into the new medicine bottle 10. During this process, the piston 810 is driven to move upward synchronously, injecting the alcohol in the liquid injection cylinder 809 into the spray pipe 814, and spraying it onto the surface of the infusion puncture needle 1102 through the atomizing spray holes to disinfect its surface and prevent bacteria in the air from infecting.

[0042] In a preferred embodiment, after placing the medicine bottle 10 to be infused into the suspension bracket 702, the limit ring 1101 is then inserted into the limit bracket 804. Under the action of the positioning bump 806, the limit ring 1101 is fixed in the inner cavity of the limit bracket 804. At this time, the infusion puncture needle 1102 is located directly below the medicine bottle 10. Then, by pushing up the handle 803, the infusion puncture needle 1102 can be inserted into the medicine bottle 10. When it is necessary to replace the medicine bottle 10, by pulling the connecting plate 802 downward by the handle 803, the infusion puncture needle 1102 can be pulled out of the medicine bottle 10. At the same time, the piston 810 is driven to move downward, and the disinfection alcohol is sucked into the injection cylinder 809. Then, a new medicine bottle 10 is replaced, and the handle 803 is pushed up to insert the infusion puncture needle 1102 into the new medicine bottle 10. During this process, the piston 810 is driven to move upward synchronously, and the alcohol in the injection cylinder 809 is injected into the spray pipe 814 and sprayed onto the surface of the infusion puncture needle 1102 through the atomizing spray holes to disinfect its surface and prevent bacterial infection from the air.

[0046] Specifically, the working principle of this clinical medicine infusion stand is as follows: When in use, under the gravity of the medicine bottle 10, the suspension bracket 702 and the first toothed plate 706 move downward, and the second toothed plate 708 is driven to move upward in the opposite direction through the gear 707. As the medicine in the medicine bottle 10 decreases and the weight of the medicine bottle 10 reduces, under the gravity of the counterweight 712, the second toothed plate 708 is driven to move downward, driving the insertion rod 713 to move downward synchronously. Until the medicine in the medicine bottle 10 is completely infused, the second toothed plate 708 drops to the lowest point, and the first contact 714 contacts the second contact 715, causing the sound and light alarm 710 to emit a sound and light alarm to notify the medical staff to come and change the medicine, which is convenient for use; as the second toothed plate 708 descends, the insertion rod 713 is driven to descend synchronously. Until when the first contact 714 contacts the second contact 715, the wedge-shaped part of the insertion rod 713 drives the wedge block 717 to move outward, driving the blocking block 719 to squeeze the infusion tube 11, causing the infusion tube 11 to bend, and the liquid medicine in the infusion tube 11 stops flowing, preventing air from entering the infusion tube 11.

[0047] After placing the medicine bottle 10 to be infused into the suspension bracket 702, then insert the limit ring 1101 into the limit frame 804, and under the action of the positioning convex block 806, fix the limit ring 1101 in the inner cavity of the limit frame 804. At this time, the infusion puncture needle 1102 is located directly below the medicine bottle 10, then the infusion puncture needle 1102 can be inserted into the medicine bottle 10 by pushing the handle 803 upward. When it is necessary to replace the medicine bottle 10, pull the connecting plate 802 downward through the handle 803, then the infusion puncture needle 1102 can be pulled out of the medicine bottle 10. At the same time, the piston 810 is driven to move downward, sucking the disinfection alcohol into the injection cylinder 809. Subsequently, replace the new medicine bottle 10 and push the handle 803 upward to insert the infusion puncture needle 1102 into the new medicine bottle 10. During this process, the piston 810 is driven to move upward synchronously, injecting the alcohol in the injection cylinder 809 into the spray pipe 814 and spraying it out from the atomizing spray holes onto the surface of the infusion puncture needle 1102 to disinfect its surface and prevent bacterial infection from the air.

[0048] When it is necessary to position the base 1, rotate the turning handle 908 to make the turning handle 908 in a vertical state. At this time, the first channel 906 is communicated with the second channel 909, and press the turning handle 908 to drive the positioning rod 901 and the suction cup 902 to move downward synchronously until the suction cup 902 adsorbs on the ground. Then rotate the turning handle 908 in the opposite direction to make the turning handle 908 in a horizontal state. At this time, the first channel 906 and the second channel 909 are misaligned, keeping the suction cup 902 in a negative pressure state to fix the base 1 on the ground and ensure the stability of the stand. And when the turning handle 908 is in a horizontal state, the long axis end of the positioning block 910 closely adheres to the inner wall of the positioning groove 911 to prevent the positioning rod 901 from moving upward.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
