Description

Technical Field

[0001] This utility model relates to the field of infusion positioning technology, specifically to an infusion support positioning device. Background Technology

[0002] Intravenous infusion refers to the administration of large doses of injectable solutions into the body via intravenous drip. During the infusion process, an infusion pump is used to control the infusion rate through the infusion tubing. Since the infusion pump needs to be used in conjunction with an infusion stand, hospitals usually fix it to the existing infusion stand using some simple connection methods. A common method of fixing it is to use screws to press the U-shaped connecting block on one side of the infusion pump against the support rod.

[0003] However, to enhance the stability of the infusion pump during use, a patent document with publication number CN208799604U proposes to reduce the friction between the infusion pump and the support adjustment plate by setting ball bearings on the connecting rod, thereby reducing the labor intensity of the operator. An anti-slip nut is also provided above the inner sleeve of the support adjustment sleeve to prevent the support adjustment plate from slipping off the upper end of the support adjustment sleeve.

[0004] Based on the above-disclosed technical content, theoretically, the implementation of the relevant technical structure is beneficial for strengthening the infusion pump. However, according to the description in the above-disclosed technical content, the infusion pump is fixed by bolt installation. Since the bolts themselves are small and a large number are used, the bolts are very easy to slip from the hands of the workers when installing or removing them, or even lose the bolts. This causes inconvenience to the workers in disassembling and assembling the infusion pump, thereby affecting the normal use of the infusion pump. Utility Model Content

[0029] Working principle: In use, firstly, the infusion pump body 1 can be moved by the rolling of the universal wheels 17 to the designated working position. Then, when the infusion pump body 1 is needed, it is placed on the tray 2, and the power of the rotary motor 20 is turned on. The turning on of the rotary motor 20 drives the moving components 14 on both sides to move towards the infusion pump body 1 simultaneously through the connection of the rotating shaft 19. Due to the threaded connection between the second ball nut 141 and the second ball screw 142, and the fact that the outer walls of the second ball screw 142 on both sides are provided with threads in opposite directions, the circumferential rotation of the second ball screw 142 on both sides drives the second ball nut 141 on its surface. Simultaneously, the pump moves towards the infusion pump body 1. At the same time, the clamping plates 3 on the left and right sides clamp the infusion pump body 1 on the left and right sides, thereby strengthening the stability of the infusion pump body 1 on the tray 2. Finally, adjust the usage height of the infusion pump body 1 according to your own needs, turn on the power of the drive motor 18. After the drive motor 18 is turned on, it drives the rotation of the lifting component 7. Due to the threaded connection between the first ball screw 702 and the first ball nut 701, the circumferential rotation of the first ball screw 702 drives the vertical lifting movement of the first ball nut 701. While the first ball nut 701 is moving, it drives the telescopic rod 4 to extend and retract inside the sleeve 5 until the infusion pump body 1 is raised or lowered to the required position.
