Embodiment 1

[0019] Such as Figure 1-2 As shown, the infusion tube for preventing blood backflow includes an infusion drip pot 1, a regulator 2, a filter 3, an infusion tube 4, and an infusion needle 5, which are connected in sequence. In the figure, the filter 3 includes a The filter 3.1 and the plastic disc 3.2, the filter 3.1 and the plastic disc 3.2 are close to each other, the diameter of the plastic disc 3.2 is consistent with the diameter of the filter, and the plastic disc 3.2 is provided with a grid that can only move in one direction Plastic sheet, the diameter of the mesh plastic sheet is smaller than the diameter of the water molecule when the mesh plastic sheet is not stretched;

[0020] When the blood flows back from the infusion needle 5, it encounters the plastic disc 3.2. Due to the grid plastic sheet in the plastic disc 3.2, the grid plastic sheet can only move in one direction, and the grid plastic sheet cannot be expanded. Therefore, Blood molecules cannot pass throug...

Embodiment 2

[0022] Such as figure 1 , image 3 As shown, the infusion tube for preventing blood backflow includes an infusion drip pot 1, a regulator 2, a filter 3, an infusion tube 4, and an infusion needle 5, which are connected in sequence. The filter 3 in the figure includes a filter sheet 3.1 and a valve body 3.2. A stopper 3.3 is provided in the valve body 3.2, a spool 3.5 is provided in the stopper 3.3, a liquid inlet is provided in the spool 3.5, and the front top plate 3.4 and the rear top plate 3.6 are respectively arranged at the front and rear ends of the spool 3.5, There is a gap between the front top plate 3.4 and the valve body 3.2, the rear top plate 3.6 is close to the valve body 3.2, and the valve core 3.5 can slide in the front and rear two blocking pieces 3.3;

[0023] When infusing, the fluid flow can be as image 3 As shown by the arrow; when the blood flows back from the infusion needle 5, the thrust of the liquid pushes the rear top plate 3.6 to move, but the liq...

Abstract

The invention discloses an infusion tube capable of preventing reverse flow of blood. The infusion tube comprises an infusion dropper, a filter and an infusion needle, wherein the infusion dropper, the filter and the infusion needle are connected by virtue of an infusion tube body; the infusion tube is characterized in that a filter sheet is arranged in the filter; and a liquid one-way piece clings to the lower side of the filter sheet. The infusion tube provided by the invention is simple in structure and low in making cost; and the infusion tube can effectively prevent the blood from reversely flowing into the part above the filter, so that the occurrence of blood complications can be reduced.

Description

technical field [0001] The invention relates to a transfusion device, in particular to a transfusion tube for preventing blood backflow. Background technique [0002] Infusion is a treatment method that people often do when they are sick. When patients are infusion, especially when they are not accompanied by family members or medical staff, blood backflow usually occurs due to failure to check or close the infusion tube in time after the infusion. If Blood returns to human body again, thereby easily causes blood disease to patient, so this just needs a kind of infusion set that prevents blood from flowing backward to solve the above problems. Contents of the invention [0003] The present invention aims at the unscientific defect of the existing transfusion device for preventing blood backflow, and provides an infusion tube for preventing blood backflow to solve the above problems. [0004] The present invention is achieved in the following way: an infusion tube for prev...
