Abstract
The utility model relates to a transfer line with tesla valve, include: the device comprises a catheter, a puncture needle head arranged at one end of the catheter, an infusion needle head arranged at the other end of the catheter, an infusion drip cup arranged on the catheter, an infusion flow regulator and a Tesla valve; the infusion drip cup, the infusion flow regulator and the Tesla valve are sequentially arranged between the puncture needle head and the infusion needle. The arrangement of the Tesla valve in the infusion tube of the utility model ensures that the fluid can basically enter the pipeline from the positive direction without obstruction and can not be obstructed; when the liquid enters reversely, the liquid flowing out of the annular branch can collide with the liquid on the inclined branch head, so that the flow of the liquid is blocked; after a plurality of branches, less liquid can flow out of the pipe orifice, so that the check valve is used, the phenomenon of backflow of the infusion can be well prevented, and the liquid of the infusion can be guaranteed to act on a human body to the maximum extent.
Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a transfer line with tesla valve.
Background
Blood backflow during infusion is a common condition in clinical infusion therapy, and particularly, when liquid is completely infused during infusion but an infusion needle and an infusion apparatus are still connected, a blood backflow phenomenon can easily occur, which is mainly caused by pressure difference. Because the transfusion needle is communicated with the blood vessel, and the pressure in the blood vessel is higher than that of the transfusion bottle, the blood can flow back to the transfusion tube along the transfusion needle.
When the situation happens, the patient often causes that the medical staff does not pull the needle in time, but in fact, the work of the medical staff is busy and cannot stop in time to deal with other things, so that unnecessary pain is brought to the patient, and unnecessary complaints are brought to the medical staff.
Aiming at the appeal of patients and medical care personnel, some tools such as infusion alarms exist in the market, but the tools avoid the phenomenon of blood backflow from the reminding angle, and the problem is not solved fundamentally. In addition, some cancer patients often have a medical fluid cost and dosage concern that the fluid in the infusion tube is desired to be completely infused into the body, and infusion alarms often fail to address this problem.
Thus, there is a need for an infusion tube provided with a tesla valve.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a transfusion tube with a Tesla valve aiming at the defects in the prior art.
In order to realize the purpose, the utility model adopts the technical proposal that:
an infusion tube provided with a tesla valve, comprising: the device comprises a catheter, a puncture needle head arranged at one end of the catheter, an infusion needle head arranged at the other end of the catheter, an infusion drip cup arranged on the catheter, an infusion flow regulator and a Tesla valve; the infusion drip cup, the infusion flow regulator and the Tesla valve are sequentially arranged between the puncture needle head and the infusion needle head.
Preferably, the catheter is made of medical polyvinyl chloride material, medical polypropylene material or medical polyethylene material.
Preferably, the infusion drip cup is made of medical polyvinyl chloride materials, medical polypropylene materials or medical polyethylene materials.
Preferably, the infusion flow regulator is made of medical polyvinyl chloride material, medical polypropylene material or medical polyethylene material.
Preferably, the tesla valve includes a plurality of pipeline branch structures alternately arranged in sequence, and the pipeline branch structure includes: a first pipeline channel, a second pipeline channel and a loop pipeline channel;
