Two-channel transfusion head of automatically controlling liquid and gas to be transfused by time phases

Abstract

The invention relates to a two-channel transfusion head of automatically controlling liquid and gas to be transfused by time phases. The two-channel transfusion head comprises an independently used transfusion head body or at least two transfusion head bodies serially connected for use. A pure gas channel and a pure liquid channel are arranged in each transfusion head body, wherein the top end of each pure gas channel is open; the bottom end of each pure gas channel is provided with a floating valve chest communicated with the bottom end of the pure gas channel; a floating valve which vertically floats is arranged in the floating valve chest; one side of each floating valve chest is communicated with a gas / liquid inlet; the top end of each pure liquid channel is also open; the bottom end of each pure liquid channel is communicated with a gas / liquid outlet; and the bottom part of each pure liquid channel is also communicated with the bottom end of the corresponding floating valve chest. According to the two-channel transfusion head of automatically controlling the liquid and the gas to be transfused by time phases, the goal that the liquid and the gas pass through the transfusion head by time phases and by channels is realized; automatic control is realized during the whole process; the goal that multiple bottles of liquid can be connected in series to be continuously transfused is achieved, and therefore, the problem that liquids are mixed when the multiple bottles of liquid are connected in series to be continuously transfused is avoided, bottle replacing operations of nurses can be reduced, and the labor strength of the nurses can be relieved.

Description

Technical field [0001] The invention relates to a medical infusion appliance, in particular to a dual-channel infusion head that automatically controls the time-sharing input of liquid and gas. Background technique [0002] The current infusion head is a simple device that strictly distinguishes the liquid and gas channels. There are many inconveniences, such as: 1. Since it cannot mix liquid and gas as a whole, it can only perform infusion operations of a single bottle of liquid, and cannot combine multiple bottles. The liquid is connected in series for continuous infusion. 2. Since the gas and liquid channels are not separated, forcibly performing continuous infusion of multiple bottles of liquid in series will result in mixing of infusion drugs and cause medical accidents. Summary of the invention [0003] The purpose of the present invention is to improve and innovate against the shortcomings and problems existing in the background art, and provide a dual-channel infusion...

[0002] The current infusion head is a simple device that strictly distinguishes the channels of liquid and gas, and there are many inconveniences, such as: 1. Because it cannot pass liquid and gas as a whole, it can only perform the infusion operation of a single bottle of liquid, and cannot put multiple bottles together. liquid series for continuous infusion

2. Since the gas and liquid passages are not separated, when multiple bottles of liquid are forced to be infused in series in series, the infusion medicine will be mixed, thus causing medical accidents
