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 sleeve seat is Y-shaped, and the side surface of a hollow cavity at the front part of the sleeve seat is provided with a branch tube which is communicated with the connecting tube. The connecting tube is made of polyester materials. The utility model has the advantages of simple structure, reasonable structure, convenient operation and easy use. When the medical staff carry out transfusion operation, the medicine can not react with a transfusion pipeline. The original property and the original performance of liquid medicine are ensured, the utility model can cause the liquid medicine to give full play to curative effect, and the patients' body health can be ensured.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of closed polyester 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.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 infuse at patient's vein, some valuable medicine (paclitaxel is the most representative) can react with the PVC material of existing connecting leg, separate out solute, and PVC is stronger to the absorption affinity of medicine, to valuable drug is a kind of waste, therefore, and when using common these medicines of venous detaining needle infusion, just can not well bring into play the curative effect of medicine, even threaten patient's body health.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, can prevent effectively that medicine and infusion pipeline from reacting, guarantee the original character of medicinal liquid and the closed polyester venous detaining needle of performance.
The technical scheme in the invention for solving the above technical problem is: a kind of closed polyester 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, it is characterized in that: casing seat is the y type, the side of its front cavity is provided with bifurcated pipe, bifurcated pipe is communicated with connecting leg, and connecting leg is to be made by polyester material.
Puncture syringe rear end described in the utility model is provided with needle handle, and needle handle is blocked in the casing seat rear end, and the one side is provided with butterfly's wing shape fin.Threeway, calparine cap and the helmet of this utility model casing seat and transfusion three way cock assembly all are to be made by non-PVC material.
This utility model is owing to adopted above-mentioned technical solution, and against existing technologies, medical personnel are when transfusion operation, and medicine can not react with infusion pipeline, guarantees the original character and the performance of medicinal liquid, makes medicinal liquid give full play to curative effect.This utility model is simple and reasonable for structure, operation, easy to use.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. sheaths among the figure, 2. sleeve pipe, 3. casing seat, 4. sealing-plug, 5. connecting leg, 6. clip, 7. threeway, 8. calparine cap, 9. end cap, 10. puncture needle tubing, 11. needle handles.
The specific embodiment
As seen from Figure 1, a kind of closed polyester of this utility model venous detaining needle mainly includes remaining needle sleeve pipe 2, casing seat 3, puncture needle tubing 10, connecting leg 5, transfusion three way cock assembly etc.This utility model connecting leg 5 is made by polyester material.Threeway 7, calparine cap 8 and the end cap 9 of casing seat 3 and transfusion three way cock assembly are also all made by non-PVC material.Can prevent that like this medicine and infusion pipeline from reacting, guarantee the original character and the performance of medicinal liquid.Sheath 1 is arranged outside the sleeve pipe 2, 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, it is through whole remaining needle sleeve pipe 2, and 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, and connecting leg 5 is to be made by polyester material, and the one end is communicated with remaining needle sleeve pipe 2 by the bifurcated pipe on the casing seat 3, the other end connects 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.Threeway 7, calparine cap 8 and the end cap 9 of this utility model casing seat 3 and transfusion three way cock assembly all are to be made by non-PVC material.Can prevent that like this medicine and infusion pipeline from reacting, guarantee the original character and the performance of medicinal liquid.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.
Puncture syringe rear end described in the utility model is provided with needle handle 11, and needle handle 11 is blocked in casing seat 3 rear ends, and the one side is provided with butterfly's wing shape fin.
This utility model is simple in structure, and is easy for operation, can prevent that medicine and infusion pipeline from reacting, and guarantees the original character and the performance of medicinal liquid, guarantees patient's body health.
