An automatic bottle-changing infusion set based on the principle of buoyancy

Abstract

An automatic bottle-changing infusion set based on the principle of buoyancy, comprising a first cork piercing head connected to a first infusion bottle, the first cork piercing head communicated with a first infusion hose, and the first infusion hose In communication with the upper first inlet of the first dropping funnel, the infusion set also includes at least two additional bottle stopper piercing heads connected with additional infusion bottles, the additional bottle stopper piercing heads are connected with the upper part of the additional infusion hose, the The lower end of the additional infusion hose communicates with the upper second inlet of the first dropping funnel, the upper part of the additional buoyancy hose extends into the lower part of the additional infusion hose, and the outer diameter of the additional buoyancy hose is smaller than that of the additional The inner diameter of the infusion hose is large, and the lower part of the additional buoyancy hose extends into the inner cavity of the first dropping funnel, and the lower part of the additional buoyancy hose communicates with the inner cavity of the additional buoyancy ball. The invention provides a buoyancy-based automatic bottle-changing infusion device with low cost and which can use different interfaces to connect a plurality of infusion bottles.

Description

technical field [0001] The invention relates to transfusion instruments, in particular to an automatic bottle-changing infusion set. Background technique [0002] The current traditional medical infusion set infusion method is to put the liquid to be infused in an infusion bottle or infusion bag, and hang it at a high place, and use gravity to make the liquid flow into the vein through the infusion leather tube. Manual adjustment is made by the governor clamp placed on the leather tube. For the automatic bottle-changing infusion device invented now, it performs bottle-changing infusion by connecting multiple bottles and multiple tubes, while other links are similar to traditional infusion methods. Transfusion through the above multiple methods has the following problems: 1) For the traditional method, the transfused person who needs to transfuse more than one bottle needs to change the bottle, and when the medical personnel are in a busy state, they cannot take care of the ...
