Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific examples, so as to help understand the content of the present invention.

[0027] Such as figure 1 Shown is a medical quantitative infusion device, which can be used for subcutaneous injection and intravenous injection, as well as a drug quantitative drug taker for intravenous infusion. It includes a housing 1 and a syringe, and a controller is installed in the housing 1, as well as a driving mechanism composed of a guide rod, a screw rod and a slide block, a servo motor or a stepping motor. Such as figure 1 As shown, the housing 1 is provided with a long hole (not shown in the figure) parallel to the guide rod so that the slider 5 protrudes out of the housing 1 through the long hole and moves up and down in the long hole, so The injection cylinder 11 of the above-mentioned syringe is installed and fixed on the housing 1 through two movable positioning parts—elastic clips 12 provide...

Abstract

The invention discloses a medical quantitative infusion device which comprises a shell and an injector, wherein a controller, a guide rod, a screw rod, a slide block and a servo motor or a stepping motor are arranged in the shell; the screw rod and the guide rod are arranged at one side in the shell in parallel; a driven shaft of the motor is connected with the screw rod; the slide block is movably sleeved on the guide rod, and the screw rod passes through a screw hole in the slide block; the controller is used for controlling the motor; a long hole which is parallel to the guide rod is formed on the shell, so that the slide block passes through the long hole and then extends out of the shell; an injection cylinder of the injector is installed and fixed on the shell through a movable positioning piece arranged on the shell; the tail end of a piston push rod of the injector is connected and positioned on the slide block through the movable positioning piece; and a key for controlling drug absorption and injection, a digital input key and a display screen for displaying data, which are connected with the controller, are also arranged on the shell. The infusion device is accurate in quantitation and convenient to use, and the injector is easy to replace.

Description

technical field [0001] The invention relates to a medical device, in particular to a quantitative infusion device capable of accurately controlling the infusion volume, which can be used for quantitative injection of drugs, especially insulin intravenous infusion for diabetics, and the syringe can be replaced. Background technique [0002] Quantitative subcutaneous injection or intravenous infusion of drugs is a widely used method in treatment. [0003] In order to improve the injection accuracy and accurately control the injection volume, some improvements have been made to the structure of the syringe, for example: [0004] The "insulin continuous quantitative syringe" of CN201267655Y is that a cylindrical push rod with thread on the outer wall is provided with grooves in the axial direction, and scale marks are arranged in the grooves; The diameter is greater than the diameter of the circular hole on the rear end of the syringe. The utility model has the advantages of s...
