Problems solved by technology

[0002] The infusion set is a medical device for infusion. The traditional infusion method is to hang the liquid in the bottle at a high place, and use the gravity to make the liquid flow into the vein through the infusion tube. When the liquid in the bottle is finished, if the medical staff does not pull out the needle in time, due to the diffusion of the liquid, the blood of the human body will flow back into the infusion tube of the infusion set, causing bacterial infection or even failure. Various medical accidents such as blood diseases endanger the personal safety of patients

Embodiment 1

[0014] Such as figure 1 The shown medical infusion set has the function of preventing blood return, including a puncture device, a drip funnel, a flow regulator, an intravenous infusion needle and a catheter, and the puncture device and the drip funnel are connected through a catheter, and also includes a sheet 4 and a support rod 6 , the puncturer is composed of an inner cylinder 5 and an outer cylinder 2, the inner cylinder 5 is connected to the catheter, the top of the outer cylinder 2 is an oblique opening, the top of the inner cylinder 5 is a flat opening, one end of the strut 6 is fixedly connected with the sheet 4, and the strut 6. The other end is inserted into the inner cylinder 5 of the trocar, and the sheet 4 can completely cover the flat mouth of the inner cylinder 5.

Embodiment 2

[0016] Such as figure 1 The difference between the shown embodiment 2 and the embodiment 1 is that the middle part of the sheet 4 is provided with raised air bubbles 1 , the raised air bubbles 1 are spherical, and the diameter of the raised air bubbles 1 is larger than the diameter of the flat opening of the inner tube 5 .

[0017] working principle:

[0018] When there is liquid in the infusion bottle 3, the sheet 4 will be suspended on the liquid, and the sheet 4 is located at the top of the strut 6. The strut 6 is very long and the height of the infusion bottle 3 is similar, and the strut 6 is inserted into the inner cylinder 5 of the piercer. Inside, the strut 6 can ensure that the sheet 4 will not float randomly in the infusion bottle 3, and after the infusion, it will fall on the flat mouth of the inner cylinder 5 of the piercer. The flat opening of 5 flows out, and as the liquid decreases slowly, the sheet 4 will also follow. When the liquid flows out, the sheet 4 will...

Abstract

The invention relates to the technical field of infusion devices, in particular to a medical infusion device with a blood return prevention function. The medical infusion device comprises a puncture device, a drip chamber, a flow adjuster, an intravenous infusion needle, a catheter, a sheet and a support rod, wherein the puncture device is connected with the drip chamber through the catheter, the puncture device comprises in inner cylinder and an outer cylinder, the inner cylinder is connected with the catheter, the top end of the outer cylinder is provided with an oblique opening, the top end of the inner cylinder is provided with a flat opening, one end of the support rod is fixedly connected with the sheet, the other end of the support rod is inserted into the inner cylinder of the puncture device, and the sheet can completely cover the flat opening of the inner cylinder. The medical infusion device with the blood return prevention function has the advantages that the medical infusion device is simple in structure and evident in effect; the sheet with a spherical protruding bubble in the middle is inserted into the inner cylinder of the puncture device, the sheet can descend along with the descending of liquid level, so that the flat opening of the inner cylinder can be sealed by the sheet after infusion, and the problem of blood return is solved effectively.
