Dropping device capable of reminding by utilizing overflow valve to conveniently control flow rate and prevent backflow

Abstract

The invention relates to the technical field of medical instruments, and discloses a drip device capable of reminding by conveniently controlling flow rate and preventing backflow by utilizing an overflow valve. The drip device comprises a bottle poking needle head, wherein the side surface of the bottle poking needle head is fixedly connected with a vent pipe; the bottom inside the bottle pokingneedle head is rotationally connected with a pressure block; the top of the pressure block is clamped with a spring; the bottom of the flow rate observation bottle is fixedly connected with an infusion tube; the bottom of the infusion tube is fixedly connected with an anti-backflow groove; the side surface of the anti-backflow groove is fixedly connected with a needle connecting pipe; and balls are movably connected inside the anti-backflow groove. According to the drip device capable of reminding by conveniently controlling the flow rate and preventing backflow by utilizing the overflow valve, the pressure of the spring is controlled by adjusting the flow rate control knob after the medicine flows into the flow rate control valve from the medicine circulation tubule, so that the flow areaformed when the medicine is pushed down the flow rate control valve opening is different, thus achieving the effect of convenient flow rate control and facilitating the control of people.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an infusion device which utilizes an overflow valve to conveniently control the flow rate and prevent backflow and remind. Background technique [0002] Nowadays, the common drip method is to put the medicine high, and then insert the leather tube for infusion into the drip bottle, and the medicine in the hanging bottle will flow out from the infusion tube to control the volume of the medicine in the tube by physically pressing the tube. The diameter of the flow, and then the pressure of the liquid in the tube is controlled by the pressure of the bottle lift, so as to control the flow rate of the drug drip. [0003] However, the problem of using this drip method is also particularly obvious. First of all, most people lie down when the hospital drips, which makes it very difficult for patients to control the flow rate of the medicine. Secondly, in this way, When the needl...
