Embodiment 1

[0037] Such as figure 1 , figure 2 , image 3 As shown, the present invention includes a liquid medicine storage and a float, the float is arranged in the liquid medicine storage, the upper end of the liquid medicine storage is fixedly connected to the liquid inlet needle 1, and the center of the lower end is provided with a vertical hole facing the cavity. To the protrusion 3, the liquid inlet needle 1 is provided with a liquid inlet 2, and the protrusion 3 is provided with a liquid outlet 4, and the float includes a floating body 5, a sealing body 8, a bottom cover 11, and a counterweight 12 , sealing body fixing sleeve, described floater is stepped structure, and described floating body 5 is hollow cone top cylinder, certainly described floating body 5 can also be other possible shapes such as solid cone top cylinder, and described sealing body 8 is Soft elastic film body, there is a longitudinal gap between the sealing body 8 and the bottom of the floating body 5, the s...

Embodiment 2

[0041] Such as Figure 4 , Figure 5 As shown, in order to ensure that the float is not skewed, the liquid medicine storage in this embodiment adopts the following structural form: the liquid medicine storage includes an upper part 13, a lower part 14, a bottom part 15, and a filter sheet 17. The upper part 13 is made of soft elastic PVC plastic, the lower part 14 and the bottom part 15 are made of hard PVC plastic, and the upper and lower ends of the upper part 13 are connected with the liquid inlet needle 1 and the bottom part respectively. The lower part 14 is fixedly connected, and the bottom end of the upper part 13 is provided with eight I vertical ribs 21 uniformly distributed along the inner periphery, and the eight I vertical ribs 21 are located at the bottom of the liquid medicine storage. In the cavity, the outer diameter of the I annular flange 6 is greater than the radial dimension of the inscribed circle between the I vertical ribs 21, so as to ensure that the b...

Abstract

The invention discloses an automatic control device of drop transfusion system, which consists of lye storage and float in the lye storage, wherein the liquid-in needle (1) with liquid-in opening (2) and vertical convex area (3) toward intracavity with liquid-out opening (4); the float contains cylindrical floater (5) and soft elastomer sealer (8). There is longitudinal gap between sealer (8) and vertical convex area (3) that matches each other. The invention provides a precise and reliable sealed transfusion system with automatic closing system effectively, which can be applied in the medical treatment domain widely.

Description

technical field [0001] The invention relates to an automatic control device for drip transfusion set. Background technique [0002] At present, intravenous infusion is a commonly used treatment method clinically. The traditional drip infusion device is to install a control valve on the infusion tube to control the switch and flow of the infusion, so that the liquid medicine can be injected into the human body at a stable flow rate, and the control valve can be closed when necessary, for example, when the infusion is about to end or When changing the dressing solution, closing the control valve can prevent air from entering the blood vessel and blood backflow into the infusion tube. The above-mentioned operation of the control valve is done manually. Intravenous infusion often takes a long time, and it is difficult to determine the exact time to complete the infusion, so constant care is required. However, patients and nurses often neglect to check t...
