Abstract
The utility model relates to a special remaining needle for a negative-pressure transfusion set, which is composed of a remaining needle tube, a transfusion guide tube, a transfusion set interface, a puncture needle inlet, a rubber plug, a puncture needle, a negative-pressure draft tube, a communication switch and a negative-pressure tube, wherein the transfusion guide tube is connected to one side of the rear end of the remaining needle tube, and the transfusion set interface is connected to the tail end of the remaining needle tube; the rear end of the remaining needle tube is connected with the puncture needle inlet , and the rubber plug is arranged in the puncture needle inlet; the negative-pressure draft tube is arranged at the rear end of the puncture needle; the communication switch is arranged on the negative-pressure draft tube; and the tail end of the negative-pressure draft tube is connected with the negative-pressure tube. The utility model has the advantages of simple structure and convenient use. When the special remaining needle is punctured under skin, the communication switch is turned on so that a medical worker can see return blood at once, so the successful puncture is ensured thereby avoiding multi-time puncture because the patient's return blood is not seen in real time, reducing patient's pains and improving puncture success rate.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to the special-purpose remaining needle of a kind of negative-pressure type transfusion device.
Background technology:
Use remaining needle very general when infusing in the clinical treatment now, but existing remaining needle is simple in structure mostly, when many times vein inanition/vein forces down, the nurse is difficult to observe blood back when implementing venipuncture, thereby have influence on nurse's judgement, cause puncture failure, repeatedly puncture, increase patient's misery, delay treatment opportunity, this kind phenomenon many old age, children's, lose blood or patient such as dehydration in common.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of rational in infrastructure, easy to use, when medical personnel puncture, can improve puncture success rate greatly, the incidence rate of injured blood vessel oppose side wall when reducing puncture.
The special-purpose remaining needle of negative-pressure type transfusion device described in the utility model relates to by keeping somewhere needle tubing, transfusion catheter, transfusion device interface, puncture needle inlet, rubber closure, puncture needle, negative-pressure drainage tube, coupling cock and negative pressure pipe and forming.Said indwelling needle tubing is similar substantially to the remaining needle of prior art, for the software biomaterial is made, can keep somewhere with patient's vein blood vessel in, be connected with transfusion catheter in rear end one side of keeping somewhere needle tubing, the transfusion catheter end is connected with the transfusion device interface, can dock with existing transfusion device, to infuse after the convenient puncture, the rear end of keeping somewhere needle tubing is connected with the puncture needle inlet, is provided with rubber closure in the puncture needle inlet, and puncture needle enters by the puncture needle inlet to be kept somewhere in the needle tubing.The rear end of puncture needle is provided with negative-pressure drainage tube, and negative-pressure drainage tube is provided with coupling cock, and the negative-pressure drainage tube end is connected with the negative pressure pipe.
The special-purpose remaining needle of negative-pressure type transfusion device described in the utility model, simple in structure, easy to use, owing to form vacuum negative pressure condition in the negative pressure bottle, when the special-purpose retained needle puncture of negative-pressure type transfusion device described in the utility model enters when subcutaneous, open coupling cock, when puncture needle thrusts vein blood vessel, because of vacuum suction, can make medical personnel see blood back at once, thereby determine puncture successfully, avoid causing repeatedly and punctured owing to patient's blood back is untimely, reduce patient's misery, improved puncture success rate.
Description of drawings:
Accompanying drawing 1 is the structural representation of the special-purpose remaining needle of negative-pressure type transfusion device described in the utility model.
