Description
Technical field
The utility model is related to technology medical appliance field, particularly relates to a kind of medical Needleless barotropic joint.
Background technology
Remaining needle is widely used to need repeatedly to carry out the occasion of transfusion in hospital for patient.With the hair of technology
Exhibition, generally connects remaining needle and extrusion infusing pipeline using needleless joint now.The use of particularly positive pressure needle-free joint becomes very
It is advantageous, positive pressure needle-free joint be it is a kind of can automatically form a positive pressure in pipeline automatically when pulling up infusion joint,
Automatically liquid is pushed to human body by pipeline, so as to avoid plugging phenomenon caused by blood to the backflow of needle tubing.
Chinese patent CN10879339B just discloses a kind of Needleless dosing positive pressure connector, and it starts glue by female Luer
The unlatching of plug, so that the liquid flowing in single direction is realized, to avoid because syringe needle punctures the particulate that may be brought, the dirt of micro- bits
Dye, when syringe is pulled up, the positive pressure connector produces a malleation, the liquid in positive pressure connector is promoted forward automatically, to keep away
Exempt from blood to return to the interior formation thrombus of remaining needle to prevent the blocking of remaining needle.But above-mentioned patent, due to complex structure, liquid
Flow resistance is big, and there is larger dead space, causes more medicament residue.
And another Chinese patent CN103071200A has carried out some improvement for these defects, cancel leading on inwall
It is simpler in chute, structure, and it makes upper lid circular cross-section into ellipse, making the residual of decoction also has certain decline.But its
Make fluid path into Y shape, liquid flowing group power and the structure of Y shape are added again, not as straight-through shape in insertion pipe operation
It is convenient, cause in the inconvenient for use of some occasions.The plug of circular cross-section coordinates with the glue shell of elliptic cross-section simultaneously one
Fixed liquor residue amount.And in the side of plug upper end, at least set to a breach.And in actual implementation process, such as this
The less words of individual notch size, plug bending effect is bad, can influence the flow velocity of liquid, in addition plug top surface withstand joint can not
Fluid path is opened in order to ensure that plug has suitable bending effect after being pressurized, this notch size preferably reaches during actual implementation
Arrive or more than plug section radius.Such breach can cause plug no matter very difficult from mould when molding or producing.
Actually excessive breach can also add the residual quantity of decoction.
Although another Chinese patent CN201520331829.X substantially overcomes drawbacks described above, provide a kind of through type,
Simple in construction, liquid flows medical Needleless barotropic joint that is more unobstructed, can reducing liquor residue amount, but in volume production process, it is this
Design high to the material performance requirement of elastic plug, and the more complicated relatively difficult from mould for causing product of structure is carried to a certain degree
Production cost is risen and in actual applications because the female Luer of the syringe adapter of in the market part manufacturer is present necessarily
Scale error, the length for causing syringe female Luer to stretch into positive pressure connector has a difference, influences positive pressure connector fluid passage
The actual degree opened, design object can be less than by causing the actual flow velocity of decoction, and extreme case even can not complete the defeated of decoction
Note.
Therefore, it is necessary to a kind of new medical Needleless barotropic joint be designed, to solve above-mentioned technical problem.
