Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The utility model discloses a fluid infusion booster unit is joined in marriage to vein's concrete embodiment one, as shown in fig. 1 to 5, including base 1, base 1's front end has the front end plate 2 and the back locating plate 3 that parallel interval set up, has the holding tank that holds the syringe on front end plate 2 and the back locating plate 3 respectively, and the bottom surface of holding tank is the arcwall face with the laminating of syringe outer wall. A positioning groove for the syringe finger flange to enter is formed between the front end plate 2 and the rear positioning plate 3, and is used for positioning the syringe in the front-rear direction. The upper end of the front end plate 2 is hinged with a clamping plate 4, and an arc-shaped groove attached to the outer wall of the injector is formed in the clamping plate 4 and used for compressing the injector.

The base 1 is fixedly connected with a fixing plate 5 right behind the through groove, and the fixing plate 5 is provided with guide holes 6 penetrating through the front side and the rear side. The intravenous fluid infusion assisting device further comprises a crank slider mechanism arranged on the base 1, and the base 1 is provided with two hinged lugs 7 which are arranged in parallel at intervals.
