Automatic bottle replacing infusion device based on buoyancy principle

Abstract

An automatic bottle replacing infusion device based on the buoyancy principle comprises a first bottle plug puncture head connected with a first infusion bottle and communicated with a first infusion hose, and the first infusion hose is communicated with a first inlet in the upper portion of a first drip chamber. The automatic bottle replacing infusion device further comprises at least two auxiliary bottle plug puncture heads connected with auxiliary infusion bottles and the upper portions of auxiliary infusion hoses, and the lower ends of the auxiliary infusion hoses are communicated with a second inlet in the upper portion of the first drip chamber. The upper portions of auxiliary buoyancy hoses extend into the lower portions of the auxiliary infusion hoses, outer diameters of the auxiliary buoyancy hoses are larger than inner diameters of the auxiliary infusion hoses, and the lower portions of the auxiliary buoyancy hoses extend into an inner cavity of the first drip chamber and are communicated with an inner cavity of an auxiliary floating ball. The automatic bottle replacing infusion device based on the buoyancy principle is low in cost and capable of being connected with a plurality of infusion bottles through different ports.

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 ...
