Abstract
The utility model relates to a closed type vein retained needle which mainly comprises a sleeve of the retained needle, a sleeve seat, a puncture needle tube, a connecting tube and a transfusion three-way joint assembly, wherein the back end of the sleeve is connected with the sleeve seat and a sealing plug is arranged in the sleeve seat. The puncture needle tube is hermetically inserted through the sealing plug to be penetrated in the sleeve of the retained needle. The sleeve seat is connected with the transfusion three-way joint assembly through the connecting tube. The back end of the puncture needle tube is provided with a needle handle which is blocked at the back end of the sleeve seat. The inner wall at the back end of the sleeve seat is axially provided with a plurality of grooves, and the front end of the needle handle is correspondingly provided with axial bulges. A wing sheet at one side of the needle handle is a flat and rectangular wing sheet. Because the rotation of the puncture needle tube and the sleeve seat can not occur and the wing sheet is flat and rectangular, the utility model can be horizontally held and can be vertically held. When the puncture operation is carried out by medical staff, the utility model has the advantages of convenient operation and high successful rate.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of sealed venous detaining needle.
Background technology
We know, venous detaining needle is a kind of medical apparatus and instruments that is used for the venous indwelling transfusion, it mainly includes remaining needle sleeve pipe, casing seat, puncture needle tubing, connecting leg, transfusion three way cock assembly, the sleeve pipe rear end is connected with casing seat, sealing-plug also is housed in the casing seat, the puncture needle tubing was inserted sealing-plug hermetically, was positioned at whole remaining needle sleeve pipe, and casing seat is connected with transfusion three way cock assembly by connecting leg.The puncture syringe rear end is provided with needle handle, and needle handle is blocked in the casing seat rear end, and the one side flatly is provided with butterfly's wing shape fin.After medical personnel use venous indwelling at the patient's vein vascular puncture, need the puncture needle tubing is extracted from casing seat rear end and remaining needle sleeve pipe, then comparatively softish sleeve portion is kept somewhere in the patient's vein blood vessel, carried out continuously to the patient or transfusion discontinuously by the remaining needle sleeve pipe.When using venous indwelling to carry out vein puncture,, rotate easily because the needle handle of puncture needle tubing and casing seat are fixing not firm at the patient, it is excessive to add butterfly's wing shape fin radian, the hand-held horizontal sliding of nurse usually causes puncture failure not smoothly, causes unnecessary misery to the patient.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple and reasonable for structure, easy for operation, and reliable sealed venous detaining needle punctures.
The technical scheme in the invention for solving the above technical problem is: a kind of sealed venous detaining needle, mainly include the remaining needle sleeve pipe, casing seat, the puncture needle tubing, connecting leg, transfusion three way cock assembly, the sleeve pipe rear end is connected with casing seat, sealing-plug also is housed in the casing seat, the puncture needle tubing was inserted sealing-plug hermetically, in the remaining needle sleeve pipe, casing seat is connected with transfusion three way cock assembly by connecting leg, the puncture syringe rear end is provided with needle handle, needle handle is blocked in the casing seat rear end, the one side is provided with fin, it is characterized in that: casing seat rear end inwall is axially arranged with several grooves, and the needle handle front end is provided with axial projection accordingly.
The fin of this utility model needle handle one side is the flat, rectangular fin.
This utility model is owing to adopted above-mentioned technical solution, and puncture needle tubing and casing seat can not rotate, and fin is a flat, rectangular, both can level control, also can vertically control, against existing technologies, medical personnel when puncture procedure, the operation, easy to use, the success rate height.

The specific embodiment
As seen from Figure 1, a kind of sealed venous detaining needle of this utility model mainly includes remaining needle sleeve pipe 2, casing seat 3, puncture needle tubing 10, connecting leg 5, transfusion three way cock assembly etc.Outside the sleeve pipe 2 sheath 1 is arranged, sleeve pipe 2 rear ends are connected with casing seat 3, and casing seat 3 back segment inner chambers also are equipped with sealing-plug 4, and puncture needle tubing 10 was inserted sealing-plug 4 hermetically, and it is through whole remaining needle sleeve pipe 2.Puncture needle tubing 10 rear ends are provided with needle handle 11, and needle handle 11 is blocked in casing seat 3 rear ends, and the one side is provided with fin 11-1.Casing seat 3 is connected with transfusion three way cock assembly by connecting leg 5.This utility model casing seat 3 is the y type, the side of its front cavity is provided with bifurcated pipe, bifurcated pipe is communicated with connecting leg 5, connecting leg 5 other ends connect threeway 7, threeway 7 two outlets in addition has nipple and calparine cap 8 and end cap 9 to spin, and medicinal liquid enters threeway 7 by calparine cap 8, the connecting leg 5 of flowing through, prop up through casing seat 3 side direction and mouthful to enter the casing seat ante-chamber and flow to sleeve pipe 2, enter vein blood vessel at last.When carrying out two kinds of medicinal liquid transfusions,, connect other transfusion apparatus and get final product as long as screw off end cap 9.
Clip 6 is housed on this utility model connecting leg 5, when the patient suspends transfusion because of needs, as long as clamp connecting leg 5 with clip 6, disconnects the connection between threeway 7 and the casing seat 3, the order transfusion takes time out to.Unclamp clip 6 when needing to recover transfusion and get final product, the operation simple and convenient.
Characteristics of the present utility model are: casing seat 3 rear end inwalls are axially arranged with several grooves 3-1, as shown in Figure 2, needle handle 11 front ends are provided with axial projection accordingly, needle handle 11 is blocked in casing seat 3 rear ends, groove 3-1 cooperates with the axial projection of needle handle 11 front ends, the two can not rotate, and has guaranteed the reliability of puncture.The fin 11-1 of this utility model needle handle one side is the flat, rectangular fin, both can level control, and also can vertically control, and has satisfied the needs of nurse's different operating custom, and is easy for operation.
This utility model is simple in structure, and is easy for operation, and puncture is reliable high.
