Description
Technical field
The present invention relates to a kind of female Luer for medical instrument pipeline, more particularly to a kind of locking ring type screwed union
And its application method.
Background technology
Female Luer is the joint form that current medical circle generally uses, and is widely used in the connection of pipeline apparatus, existing Shandong
Your connector is divided into common Luer connector and locking female Luer, and the use of locking-type female Luer is more extensive, but locking-type
The defects of female Luer also has it when in use, one, which is locked out formula female Luer, needs to rotate whole connector when in use, its institute
Related pipeline also can be rotated and then, and torque so will result in pipeline kink, particularly thinner often at 540 ° or so
In the application of pipeline, it is easy to cause pipeline bending, influence fluid path；Second, clinically the use habit of medical staff is very
Difference, some are compared with nurse and do not like using the connector with locking device, but are difficult separately to purchase during hospital's buying, use
Clinical staff of the apparatus smoothly yet to line operation does not cause certain puzzlement.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides one kind to lock ring type screwed union, using split type ring
Shape latch-up structure, when use, only need to rotate locking ring without rotating whole connector, solve the related rotation pipeline of swivel
Caused security risk, and devise slope dentalation in connector afterbody, to realize the dismounting of locking ring, allows medical staff
The apparatus in hand can be reequiped according to the demand of oneself, creates great convenience.
To achieve the above object, used technical solution is the present invention：One kind locking ring type screwed union, including one
Connector, and a tubulose retainer ring, one end of the connector are pipeline ends, and the other end is Rule male contact end, the retainer ring
Inner wall is equipped with internal thread, and the Fixing shrink ring is connected on connector close to the position at Rule male contact end, the pipeline of the connector
A caliber is further connected with end and is more than pipeline end connecting tube, in the connecting tube, two strips are equipped with the junction at pipeline end
Double wedge, the non-conterminous side of described two strip double wedges are respectively equipped with a bevel edge, and the connector is close to the outer of Rule male contact end
An annular boss is additionally provided with wall, the retainer ring is additionally provided with a slot pipe close to pipeline end side, the slot pipe
Internal diameter is slightly larger than the outside diameter at pipeline end, is equipped with less than the outside diameter of annular boss, and less than the outside diameter of connecting tube, the slot pipe
Two axisymmetric notches, the gap width are more than strip convex tooth width.
The application method of ring type screwed union is locked, in use, Rule male contact of ring type screwed union will be locked first
End is connected with Rule famale connector of apparatus, then pushes retainer ring to Rule famale connector, and with the outer spiral shell on Rule famale connector
Line bolt, after use, contrahelical exits retainer ring to pipeline end and connecting tube intersection, need to such as dismantle retainer ring,
Retainer ring is then pushed into pipeline end and connecting tube junction first, notch is placed on strip double wedge, firmly rotation fixed ring makes
Strip double wedge is pushed in slot end along bevel edge, and the internal diameter at slot end is expanded to identical with connecting tube at this time, you can dismounting retainer ring.
The beneficial effects of the invention are as follows：Using split type ring-type latch-up structure, since its movable fixes ring design, make
Used time no longer needs to rotate whole connector, but only needs to rotate retainer ring, you can realizes and wants to connect Rule famale connector of apparatus
Be spirally connected the purpose of locking, solve the related rotation pipeline of swivel caused by security risk, considerably reduce in clinic
In use due to pipeline twist together and caused by plugging, liquid cutout etc. clinical treatment accident, and the present invention connector afterbody design
Slope dentalation, by the way that the slot pipe of retainer ring afterbody to be pushed to the slope of strip double wedge, realizing the dismounting of locking ring,
Allow medical staff to reequip the apparatus in hand according to the demand of oneself, created greatly just for the Clinical practice of medical staff
Profit.

Embodiment
As shown in Figs. 1-3, locking-type screwed union is identical in the prior art, and locking ring type screwed union 1 includes one
Connector 1-1, and one end of tubulose a retainer ring 1-2, connector 1-1 are pipeline end 1-1-1, the other end is Rule male contact end 1-
1-2, retainer ring 1-2 inner wall are equipped with internal thread 1-2-1, and retainer ring 1-2 is socketed on connector 1-1 close to Rule male contact end 1-
The position of 1-2.
As illustrated in figures 4-5, a caliber is further connected with the pipeline end 1-1-1 of connector 1-1 and is more than pipeline end 1-1-1 connecting tubes
On 1-1-3, connecting tube 1-1-3, two strip double wedge 1-1-3-1, two strip double wedges are equipped with the junction of pipeline end 1-1-1
The non-conterminous side of 1-1-3-1 is respectively equipped with a bevel edge 1-1-3-2, and connector 1-1 is on the outer wall of Rule male contact end 1-1-2
It is additionally provided with an annular boss 1-1-4.
As shown in fig. 6, retainer ring 1-2 is additionally provided with a slot pipe 1-2-2, slot pipe 1- close to pipeline end 1-1-1 sides
The internal diameter of 2-2 is slightly larger than the outside diameter of pipeline end 1-1-1, less than the outside diameter of annular boss 1-1-4, and is less than the outside diameter of connecting tube,
