According to the indwelling needle, a soft duct can be inserted in the mammary duct conveniently, a contrast agent in the agent adding chamber is injected in a designated position accurately via the injection channel, and a hard needle head can also be used normally for injection of other parts. The indwelling needle has two injection ports and three modes and can be changed at will as required, so that the injection efficiency is guaranteed, and the pain of patients can be relieved.
Description
Technical field
This utility model relates to medical treatment consumptive materials field, relates in particular to a kind of delay pin for breast duct.
Background technology
Being detained pin is in order to facilitate patient to reuse, a part is trapped in patient body, can with the syringe needle of combinations of syringe practicality, thereby reduce the misery that multiple injection is brought to patient.Existing delay pin front end is too sharp-pointed, is not suitable for parading in breast duct.On the other hand, must injection of contrast medium when Diagnosis of Breast pathological changes, metal needle cannot direct injection in breast duct, and cannot guarantee the accuracy of injection.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, this utility model provides a kind of delay pin that facilitates injection of contrast medium for breast duct.
Technical scheme: for achieving the above object, a kind of delay pin for breast duct of the present utility model, comprise combined delay needle body and puncture needle body, described delay needle body comprises the soft syringe needle of sleeve and front end, described puncture needle body comprises the first connector that is plugged on described sleeve rear end, and be arranged on described the first connector front end and be coated on the metal needle in soft syringe needle, described the first connector can be arranged in syringe needle, it is characterized in that: described metal needle front end is blunt round structure, metal needle front side has side mouth, described barrel bore is provided with slider makes described slider and forward sleeve chamber formation add agent chamber, described sleeve is adding an injection canal of side, agent chamber interpolation.
In order to guarantee that syringe needle walks process and can not hurt breast duct, metal needle front end of the present utility model changes blunt round structure into.Described soft syringe needle is that medical soft plastics are made.When being detained needle body and the combination of puncture needle body, the first connector can being arranged in syringe needle and injecting; Puncture needle body is pulled back from being detained needle body, when the side mouth of metal needle and front port are all positioned at while adding agent chamber, can be by syringe, contrast-medium injection is indoor to adding agent, then inject by injection canal simultaneously.
In order to facilitate metal needle puncture, play sealing process simultaneously, described slider is that rubber or foamed materials are made.
As further optimization of the present utility model, delay pin of the present utility model also comprises the second connector and puncture cap, and described injection canal is arrived by soft pipe connection in described second connector one end, the other end and syringe needle form fit; Described the second connector is connected with described puncture cap spiral, and described puncture cap inner chamber is provided with the guide pipe of walking for syringe needle, and puncture cap rear end is embedded with rubber bodies.Puncture cap is screwed to lower time, and the second connector can be installed in another syringe needle; Or, puncture cap is installed on the second connector, utilize the syringe puncture rubber bodies that syringe needle is installed to inject.
As further optimization of the present utility model, described the first connector side is provided with handle, when the first connector and sleeve are when combined, between described handle and sleeve lateral wall, leave gap, form flow-stopping clip structure, can, by hose clamp in gap, between handle and sleeve lateral wall, can play fluid stopping effect.
As further optimization of the present utility model, described handle surfaces is provided with anti-slip veins.
Further, in order to guarantee not wear and tear between metal needle and sleeve lining, described barrel bore front end is provided with metal centrum, and metal needle more easily inserts in soft syringe needle under the conical surface guiding of metal centrum.
Beneficial effect: a kind of delay pin for breast duct of the present utility model is convenient to be inserted soft conduit in breast duct, utilize injection canal to be accurately expelled to assigned address by adding the indoor contrast agent of agent, also can normally use hard syringe needle for the injection at other positions.Delay pin of the present utility model is used flexibility ratio very high, has two injection ports, and three kinds of modes, can arbitrarily change according to user demand, have guaranteed injection efficiency, alleviate patient suffering.
