Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of no-needle transfusion connector.
Background technique
With the development of modern medical service technology, venous detaining needle technical application is popularized.And the country clinically makes now
It is calparine cap, due to 1-500 microns of particle diameter of the rubber grain of calparine cap, easily causes rubber through puncturing repeatedly
Particles from getting loose enters blood circulation, so easily blood is caused to pollute；Nursing staff serve at a hospital in be also faced with easily by
Injection needle such as stabs at the occupational risks.With the appearance of Needleless seal transfusion technology, no-needle transfusion connector can be to avoid using needle
Head punctures repeatedly, reduces medical staff and is wounded by stabbing；With positive pressure system, avoids backflow of blood from entering pipeline and result in blockage, facing
It is easy to operate on bed, it is easy to use, it can be connect with syringe, infusion apparatus and blood transfusion apparatus etc..Full-closed infusion reduces infection
Chance, compensate for deficiency of the needle transfusion system in clinic.
In the U.S., calparine cap was just disabled completely early in 1994.Therefore exploitation is without danger and without the needleless for using limitation
The demand of airtight positive pressure infusion connector has seemed further urgent.
Utility model content
Purpose of the utility model is to solve the above-mentioned problems of the prior art, devises a kind of no-needle transfusion and connect
Head.
Realize that above-mentioned purpose the technical solution of the utility model is a kind of no-needle transfusion connector, including shell, the shell
Inside is equipped with piston, is equipped with end cap on the left of the piston.
The enclosure interior shoulder and piston land form sealing structure.
Novel needle street corner material is silica gel, medical grade polycarbonate, polyethylene, is free of latex.
When the piston upper end reaches shell 5-8mm depth, there is deformation space, it is logical to form water conservancy diversion with outer casing inner wall
Road.Lower section diameter is bigger than upper section, and lower end design has two circular hole runners.
A kind of no-needle transfusion connector made using the technical solution of the utility model, the present apparatus is simple to operation, prevents
Blood infection supports bolus, all venous transfusion programs, unique Interface design is suitble to provide simple and direct access way
Reduce infection and the related complication of patient's indwelling intravenous needle and conduit simultaneously, mitigate nursing staff's workload, protects medical care
The health of personnel.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of no-needle transfusion connector described in the utility model；
Fig. 2 is a kind of exploded view of no-needle transfusion connector described in the utility model；
In figure, 1, shell；2, piston；3, end cap.
Specific embodiment
The utility model is specifically described with reference to the accompanying drawing, as shown in Figs. 1-2, a kind of no-needle transfusion connector, packet
Shell 1 is included, piston 2 is equipped on the inside of the shell 1, is equipped with end cap 3 on the left of the piston 2；1 inner circular bead of shell and piston
Shoulder forms sealing structure；A kind of no-needle transfusion joint material is silica gel, medical grade polycarbonate, polyethylene, without cream
Glue；When 2 upper end of piston reaches shell 5-8mm depth, there is deformation space, form flow-guiding channel with outer casing inner wall.Under
Section diameter is bigger than upper section, and lower end design has two circular hole runners.
The characteristics of the present embodiment is that case inside is equipped with piston, is equipped with end cap on the left of piston.The present apparatus is simply easily grasped
Make, prevents blood infection, support bolus, be suitble to all venous transfusion programs, unique Interface design simple and direct in offer
Access way reduces infection and the related complication of patient's indwelling intravenous needle and conduit simultaneously, mitigates nursing staff's workload,
Protect the health of medical staff.
In the present embodiment, there is piston 2 moving up and down in shell 1；It is deep that 2 upper end of piston reaches shell 5-8mm
When spending, there is deformation space, form flow-guiding channel with outer casing inner wall.Lower section diameter is bigger than upper diameter, and lower end design has two
Circular hole runner；When needing to be transfused, by the needleless interface on external 6:100 plug insertion connector top, piston 2 is pushed downwards
It is dynamic, it is designed harder 2 upper section of piston downlink pressure 2 lower section of piston therewith, makes two circular holes and joint housing of 2 lower section of piston
1 inner wall forms liquid guide flow channel；When infusion is completed and pulls out 6:100 plug, 2 uplink of elastic piston makes piston 2 and shell
It is realized between body 1 closed again.Thereby realize the needleless connection for the safety that can be plugged repeatedly.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology people of the art
Member embodies the principles of the present invention to some variations that some of them part may be made, and belongs to the utility model
Within protection scope.
