Embodiment Construction

[0011] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0012] An intravenous infusion set, such as figure 1 As shown, it includes a drip pot 2, the front end of the drip pot 2 is airtightly connected with a liquid inlet pipe 1, and the rear end of the drip pot 2 is airtightly connected with a liquid outlet pipe 6, and the liquid outlet pipe 6 is provided with a flow rate regulator 7. There is a floating plug 4, the floating plug 4 is an inverted cone, the lower end of the floating plug 4 corresponds to the inlet of the liquid outlet pipe 6, there is an air bubble 3 inside the floating plug 4, the lower end of the floating plug 4 is connected with a drop rod 5, the drop rod 5 is located in the outlet pipe 6, and the floating plug 4 and the drop rod 5 are in one structure...

Abstract

The invention discloses an intravenous infusion apparatus which is safe in use and comprises a drip pot. A liquid inlet tube is hermetically communicated with the front end of the drip pot, a liquid outlet tube is hermetically communicated with the rear end of the drip pot, a flow rate regulator is arranged on the liquid outlet tube, a floating plug is arranged in the drip pot and is an inverted cone, the lower end of the floating plug corresponds to an inlet of the liquid outlet tube, a bubble is arranged inside the floating plug, a falling rod is connected to the lower end of the floating plug and is positioned in the liquid outlet tube, and the floating plug and the falling rod are of integral structures. The intravenous infusion apparatus has the advantages that in an intravenous infusion procedure, the floating plug constantly floats under the action of buoyancy of liquid medicine, normal infusion is unaffected, the floating plug falls to the inlet of the liquid outlet tube under the action of the gravity of the floating plug when the liquid medicine in the drip pot is thoroughly dripped, the liquid outlet tube can be plugged owing to the fact that the floating plug is the inverted cone, liquid medicine is prevented from continuing being infused into a human body, blood return is effectively controlled, and accordingly the intravenous infusion apparatus is safe and reliable when used.

Description

technical field [0001] The invention relates to a medical device for intravenous infusion, in particular to a blood return preventing transfusion device. Background technique [0002] At present, many patients cannot be detected in time due to various reasons when the intravenous infusion is completed, and the medicinal liquid in the infusion bottle is completely dripped so that blood returns, which brings panic to patients and medical staff. Contents of the invention [0003] The invention aims at the deficiencies and provides a blood return preventing infusion set which is safe to use. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] An intravenous infusion set, comprising a dripping pot, the front end of the dripping pot is sealed and connected with a liquid inlet pipe, and the rear end of the dripping pot is connected with a liquid outlet pipe in a sealed manner, and a flow rate re...
