Description

A kind of Novel intravenous catheter

Technical field

This utility model is related to a kind of medical apparatus and instruments, and in particular to a kind of Novel intravenous catheter.

Background technology

The use of venous detaining needle can reduce patient because repeatedly venipuncture and the pain that causes and to have an injection probably Fear sense, mitigate the impatience of family members, be easy to clinical application, anxious, the rescue medication of critical patient to mitigate the workload of nurse, The pain of patient is reduced, thus venous detaining needle is widely used in clinic.

Remaining needle mainly includes indwelling needle, the indwelling flexible pipe of indwelling needle front end, puncture needle and puncture needle needle handle, core Center portion part can be just the indwelling flexible pipe and puncture needle being retained in human vas, by indwelling flexible pipe and puncture needle one when using The Ink vessel transfusing punctured into human body is acted, after indwelling flexible pipe is completely into blood vessel, puncture needle is withdrawn out, so as to indwelling flexible pipe be stayed in Ink vessel transfusing further carries out infusion treatment.

In the containing needle structure for commonly using on the market at present, indwelling needle is round tube shape structure, and by centre It is gradually reduced toward one end radius, wherein it is larger for interting the back segment radius of remaining needle and puncture needle needle handle, for connecting indwelling The leading portion radius of flexible pipe and interspersed puncture needle tip portion is less.Such structure there is a problem of in use one it is larger, It is exactly after retained needle puncture use, because back segment and leading portion radius are different and in setting is gradually reduced, indwelling flexible pipe is retained in There is angle difference with the remaining needle back segment for being exposed to human external after Ink vessel transfusing, be easily caused indwelling flexible pipe long-time and use Afterwards pipeline is not smooth, and then affects the normal infusion of remaining needle.

The content of the invention

This utility model purpose is to provide a kind of Novel intravenous catheter, by the improvement to structure so that remaining needle exists Long-time is not easily blocked using rear pipeline, it is ensured that the normal infusion of remaining needle.

The technical solution of the utility model is：A kind of Novel intravenous catheter, including indwelling needle, indwelling flexible pipe, puncture Pin and puncture needle needle handle, the indwelling needle is cylindric setting, and the indwelling needle length is 35mm, and radius is 2mm, in institute State and be provided with vertically on indwelling needle inwall an inner tube, said inner tube length be 6-9mm, the end of said inner tube one end with it is described One end end of indwelling needle flushes and hose connection with the indwelling, and the said inner tube other end is another with the indwelling needle A rubber batching pig is provided between end.

Further technical scheme, to correspond to the indwelling needle outer wall of said inner tube position as top, in the remaining needle The side wall of seat is provided with a fixed-wing.

Further technical scheme, the fixed wing surface is provided with some salient points.

Further technical scheme, the fixed-wing is silica gel fixed-wing.

The utility model has the advantages that：Indwelling needle is cylindric setting in this utility model, on indwelling needle inwall edge An axially arranged inner tube, one end end of inner tube is hose connection with indwelling so that remaining needle when in use indwelling needle bottom with There is no angle difference, indwelling flexible pipe in same level, as compared with the past between indwelling flexible pipe and indwelling needle in interior bottom of the tube It is not easily blocked after a long time use, it is ensured that remaining needle is normally used.

Specific embodiment

Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：

Embodiment one：Referring to shown in Fig. 1,2, a kind of Novel intravenous catheter, including indwelling needle 1, indwelling flexible pipe 2, wear Pricker 3 and puncture needle needle handle 4, the indwelling needle is cylindric setting, and the indwelling needle length is 35mm, and radius is 2mm, It is provided with an inner tube 5 vertically on the inwall of the indwelling needle 1, said inner tube length is 6-9mm, the end of the one end of said inner tube 5 Portion flushes with one end end of the indwelling needle and is connected with the indwelling flexible pipe 2, the other end of said inner tube 5 and the indwelling A rubber batching pig 8 is provided between the other end of needle stand 1.

The outer wall of indwelling needle 1 with correspondence said inner tube 5 position is provided with one as top on the side wall of the indwelling needle Fixed-wing 6, the surface of the fixed-wing 6 is provided with some salient points 7, and the fixed-wing is silica gel fixed-wing.The setting of fixed-wing is just In remaining needle is integrally attached to into human body surface using adhesive tape.

When in use, puncture procedure is identical with existing retained needle puncture operation for remaining needle of the present utility model, first will Indwelling flexible pipe and puncture needle puncture together the Ink vessel transfusing into human body, and puncture needle is then outwards exited again, and then indwelling flexible pipe is stayed Put in intravascular, then reach the medicinal liquid for needing to be input into human body Jing after transfusion needle punctures through batching pig in inner tube, now medicinal liquid Just can pass through in inner tube and indwelling flexible pipe input human body.Because indwelling needle is cylindric setting, in indwelling needle inwall Axially disposed inner tube, one end end of inner tube is hose connection with indwelling so that indwelling needle indwelling needle bottom when in use With interior bottom of the tube and indwelling flexible pipe bottom in a horizontal plane, there is no angle between indwelling flexible pipe and indwelling needle as compared with the past Degree difference so that indwelling flexible pipe is after a long time use not easy to blocking, it is ensured that remaining needle is normally used.

Certainly above-described embodiment its object is to allow and be familiar with this only to illustrate technology design of the present utility model and feature The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this Enclose.The modification that all spirit according to this utility model main technical schemes are done, all should cover in guarantor of the present utility model Within the scope of shield.
