Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion device for automatically replacing an infusion bottle. Background Art

[0002] Infusion, also known as drip or hanging water, is a large dose of injection into the body through intravenous drip. The liquid medicine is usually packaged in a glass or plastic infusion bottle or bag. When used, the infusion bottle or bag is hung upside down on a bracket, and the liquid medicine is injected into the human vein through an infusion device. In the process of medical care, nurses need to frequently infuse patients.

[0003] In the infusion room or ward, some patients sometimes need to receive multiple bottles of infusion continuously.

[0044] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] See also Figures 1 to 5 , an infusion device for automatically replacing an infusion bottle, comprising:

[0046] The infusion bottle fixing box 1 has a plurality of accommodating chambers 11 arranged side by side inside, so that a plurality of infusion bottles of the same patient can be placed in the adjacent plurality of accommodating chambers 11 respectively. A through hole 12 is provided in the middle of the bottom wall of each of the accommodating chambers 11. After the infusion bottle 21 is placed upside down in the accommodating chamber 11, its bottle mouth is exposed from the lower end of the through hole 12, so that the plastic puncture needle on the infusion tube can be inserted. The upper end of the infusion bottle fixing box 1 is provided with an openable cover plate 13, so that the infusion bottle 21 can be taken in and out;

[0047] The fixing component 3 is used to fix the plastic puncture needle 2 and is arranged in the installation box 37 at the lower end of the infusion bottle fixing box 1. The fixing component 3 is movably arranged at the lower end of any of the through holes 12. The top and the front side of the installation box 37 are hollowed out. The hollowing out of the front side facilitates the insertion of the plastic puncture needle 2 and the use of the fixing component 3 to fix it; the hollowing out of the top facilitates the insertion and removal and left and right movement of the plastic puncture needle 2.

[0048] The automatic replacement mechanism 4 includes an electric telescopic column 41 disposed at the lower end of the fixing assembly 3 and a slider 42 disposed at the lower end of the electric telescopic column 41. The slider 42 is slidably disposed in a slide groove 43 provided on the bottom wall of the installation box 37. A driving mechanism 44 is provided in the installation box 37 for causing the slider 42 to slide back and forth along the slide groove 43. The electric telescopic column 41 is used to insert or remove the plastic puncture needle 2 from the infusion bottle mouth. The driving mechanism 44 can drive the slider 42 to slide back and forth along the slide groove 43, thereby driving the plastic puncture needle 2 to switch between the lower ends of different through holes 12. The remaining electric telescopic columns 41 cooperate to achieve the purpose of replacing the infusion bottle.

[0049] The displacement sensor 5 is arranged in the slide groove 43, and the moving end of the displacement sensor 5 is installed on the slider 42; the displacement sensor 5 can monitor the position of the slider 42 in the slide groove 43, so as to cooperate with the controller 6, the electric telescopic column 21 and the driving mechanism 44 to accurately and automatically insert the plastic puncture needle 2 into the bottle mouth of the infusion bottle 21 without manual control of the position;

[0050] The controller 6 is arranged on the installation box 37 and is electrically connected to the displacement sensor 5, the electric telescopic column 41 and the electrical components of the driving mechanism 44. When the infusion bottle needs to be replaced, the controller 6 starts the electric telescopic column 41 to pull the plastic puncture needle out of the completed infusion bottle according to the patient's needs, and then starts the driving mechanism 44 and the displacement sensor 5. The driving mechanism 44 drives the plastic puncture needle 2 to move to the lower end of the next infusion bottle. At the same time, the displacement sensor 5 transmits the position information of the slider 42 monitored to the controller 6. The controller 6 compares the information with the internal value. If it reaches the lower end of the next infusion bottle, the driving mechanism 44 is controlled to be closed, and then the electric telescopic column 41 is controlled to be started to achieve the purpose of inserting the plastic puncture needle 2 into the next infusion bottle.

The slider 42 is inserted into the outer wall of the screw rod 441 through a thread, and the screw rod 441 is rotatably connected to the inner wall of the slide slot 43 through a bearing 443.

[0054] The motor 442 is electrically connected to the controller 6 .

[0055] Preferably, the front and rear side walls of the through hole 12 are respectively threadedly connected with second locking bolts 14, and the inner ends of the second locking bolts 14 are respectively rotatably connected to arc-shaped fixing clips 16, and the two arc-shaped fixing clips 16 are symmetrically arranged. By screwing the second fastening bolts 14, the arc-shaped fixing clips 16 can clamp and fix the bottle mouth of the infusion bottle 21, effectively preventing the infusion bottle from moving up and down when inserting and removing the plastic puncture needle 2, making the operation more stable and reliable.

[0056] Preferably, the inner wall of the through hole 12 is also provided with a liquid level sensor 7, and the liquid level sensor 7 is electrically connected to the controller 6. The liquid level sensor 7 can monitor the liquid level in the infusion bottle 21, thereby transmitting the monitored liquid level signal to the controller 6. The controller 6 can judge whether it is necessary to start the automatic replacement mechanism 4 by comparing the signal with the internal value, without manually checking the liquid remaining in the infusion bottle 21, which greatly reduces the physical and psychological burden of the patient and the family, especially when the patient is not accompanied by his family, which improves the patient's nursing experience and is more humane.

[0057] Preferably, the installation box 37 is also provided with a battery 8, which can provide sufficient power for each electrical component to ensure its normal operation.

[0058] Preferably, one end of the cover plate 13 is connected to one side of the upper end of the box body of the infusion bottle fixing box 1 through a hinge, and the other sides of the two are connected through a buckle.

[0059] Preferably, a handle 15 is provided in the middle of the upper end of the cover plate 13 .

[0060] Preferably, the rear side of the infusion bottle fixing box 1 is further provided with a fixing clamp 9 for connecting with the infusion stand, and a fastening bolt 91 is also penetrated on the side wall of the fixing clamp 9.
