Problems solved by technology

[0002] At present, there have been many reports on infusion sets and related technologies, and there are as many as 3,000 patent applications, and there are various products on the market. These infusion sets have airtight air-proof or other functions, but when realizing their advantages, There is also the most fatal defect, that is, after the injection liquid is dripped, due to the change of the air pressure in the infusion tube, the blood in the human body will flow back into the infusion tube, resulting in the defect of blood backflow, which brings great harm to medical treatment. Certain negative effects

Abstract

An infusion apparatus capable of preventing blood from flowing back through sustained release of a micropore passageway comprises a drip chamber (1), wherein a floating body (2) is arranged in the drip chamber (1). The infusion apparatus is characterized in that the micropore passageway (3) which is communicated with a drip tube (9) connected with the drip chamber is arranged on the lower portion of the drip chamber (1). The infusion apparatus has the advantages that by utilizing a fiber stick as the medium, air pressure and residual liquid in the drip chamber are guaranteed to be communicated with liquid in the drip tube and blood pressure of the human body all the time, air is prevented from flowing into and out of the drip tube, liquid is guaranteed to drop out of the drip chamber in a certain period of time, the blood of the human body is prevented from flowing back in a certain period of time, more time is saved for a nurse, the nurse can freely replace an infusion bottle, and the apparatus is simple in structure, safe to use, good in trail effect in hospitals, and capable of delaying the blood return time by at least 15 minutes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an infusion set and a method thereof which use microporous channels for slow release and prevent blood backflow. Background technique [0002] At present, there have been many reports on infusion sets and related technologies, and there are as many as 3,000 patent applications, and there are various products on the market. These infusion sets have airtight air-proof or other functions, but when realizing their advantages, There is also the most fatal defect, that is, after the injection liquid is dripped, due to the change of the air pressure in the infusion tube, the blood in the human body will flow back into the infusion tube, resulting in the defect of blood backflow, which brings great harm to medical treatment. Certain negative effects. Contents of the invention [0003] The object of the present invention is to study a kind of infusion device and its method tha...
