Abstract
The utility model discloses a heparin cap which is provided with a turnable inner screw thread closing ring, being constituted by the connecting of the turnable inner screw thread closing ring and a Ruhr external cone noumenon. The rear wall of the inner screw thread closing ring is provided with a connecting hole; the rear part of the Ruhr external cone noumenon is provided with a convex ring whose diameter is slightly bigger than the connecting hole; the rear part of the convex ring forms a connecting groove. When rotating the inner screw thread closing ring to make the heparin cap connected with the other machines, the Ruhr external cone noumenon will not rotate along with inner screw thread closing ring so as to prevent the piercing instrument inserted in the Ruhr external cone noumenon from falling off and prevent the back stay pipe from kinking.
Description
Technical field
This utility model relates to a kind of calparine cap.
Background technology
Calparine cap is a kind of connecting piece of the class medical apparatus and instruments that is used to infuse, its effect is can realize connection by the 6% Rule outer cone and the medical apparatus and instruments of other band Rule inner cone when needing, and carry medicinal liquid or extract body fluid such as blood by this medical apparatus and instruments, with convenient treatment or sampling.
The structure that the locked joints body of existing calparine cap is designed to 6% Rule outer cone and female thread collar part one or fixedlys connected, the calparine cap of this structure is in use when screwing the screw thread collar, whole calparine cap and then rotates together, and be connected at lancet device under the situation of calparine cap, this processing ease cause lancet device to screw out to come off or after connect the phenomenon that conduit produces kink, brought adverse influence to subsequent operation.
In addition, rubber cushion in the existing calparine cap adopts material such as binding agent or back-up ring or structure to fix usually, this fixed form is in the lancet device back off procedure, when the frictional force between lancet device and the rubber cushion surpasses bond strength between rubber cushion and the locked joints, exist the risk that rubber cushion comes off from locked joints.
Summary of the invention
The purpose of this utility model is: a kind of calparine cap of being furnished with rotatable female thread collar is provided, this calparine cap is connected the female thread collar with Rule outer cone body split, when rotation female thread collar makes calparine cap be connected with other medical apparatus and instruments, Rule outer cone body can not produce transfer, thus can avoid having inserted lancet device in the outer cone body of Rule comes off and lancet device after connect the phenomenon that conduit produces kink.
The technical solution of the utility model is: a kind of calparine cap of being furnished with rotatable female thread collar, this calparine cap is connected to form by female thread collar and Rule outer cone body, the female thread collar is horizontal concave body, inwall is provided with female thread, rear wall is provided with connecting hole, Rule outer cone body is horizontal convex shape, the front portion is Rule outer cone, and the rear portion is an annular seal space, and the center is a fluid passage, annular seal space is built-in with rubber cushion, the rear portion of Rule outer cone is provided with the protruding circle of slightly larger in diameter in connecting hole, and protruding circle rear portion forms link slot, when Rule outer cone body inserts the connecting hole of female thread collar, protruding circle is positioned at before the connecting hole, and the hole wall of connecting hole snaps in the link slot.
The further technical scheme of this utility model is: a kind of calparine cap of being furnished with rotatable female thread collar, this calparine cap is connected to form by female thread collar and Rule outer cone body, the female thread collar is horizontal concave body, inwall is provided with female thread, rear wall is provided with connecting hole, Rule outer cone body is horizontal convex shape, the front portion is Rule outer cone, and the rear portion is an annular seal space, and the center is a fluid passage, annular seal space is built-in with rubber cushion, the rear portion of Rule outer cone is provided with the protruding circle of slightly larger in diameter in connecting hole, and protruding circle rear portion forms link slot, when Rule outer cone body inserts the connecting hole of female thread collar, protruding circle is positioned at before the connecting hole, and the hole wall of connecting hole snaps in the link slot; The extension that slightly curves inwardly of described annular seal space rear aperture forms one and shrinks edge, shrinks edge and contact with the rear end face of rubber cushion, and stop that by shrinking edge rubber cushion retreats, the diameter of circular hole that shrinks edge formation less than rubber cushion greater than the lancet device that punctures.
The utility model has the advantages that:
1. this utility model is connected the female thread collar with Rule outer cone body split, when rotation female thread collar makes calparine cap be connected with other medical apparatus and instruments, Rule outer cone body can not produce transfer, thus can avoid having inserted lancet device in the outer cone body of Rule comes off and lancet device after connect the phenomenon that conduit produces kink.
2. rubber cushion of the present utility model is fixed by the contraction edge that the annular seal space rear aperture adopts heat seal process to form, and without binding agent, do not increase other member, the rubber cushion after heat seal is fixed is completely restricted in annular seal space, can not return because of lancet device to come off.
