Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of insulin pump extrusion infusing pipeline structure.
Background technology
Caused by diabetes are due to human pancreas' excreting insulin deficiency or are unable to excreting insulin, pancreas does not secrete pancreas
The diabetes patient of island element and part hypoinsulinism, coordinates extrusion infusing pipeline at regular time and quantity toward defeated in body using insulin pump
Insulin is noted, to reach the pancreatic secretion insulin of normal person, this also proposes requirement to the extrusion infusing pipeline of insulin.
Insulin pump mainly completes the connection with remaining needle 2 ' with infusion tube using plastic rivet 1 ' at present, such as Fig. 1 institutes
Show, which is completed by mold injection, and due to the limitation of technology and material, the wall thickness equidimension of plastic rivet 1 ' is general
Larger, when it is connected with the size interference of remaining needle 2 ', the internal diameter of remaining needle 2 ' can be stretched, which is easy to bring two masters
Want problem：First, remaining needle 2 ' rises brokenly, insulin is caused to reveal；Second, at rivet tip outside the outer end face of needle stand 3 ', indwelling
Pin 2 ' be easy to cause broken pipe, so as to cause plugging in use since large deformation causes tube wall thinning.Both of which pair
Infusion of insulin causes very big influence.
The content of the invention
It is an object of the invention to provide a kind of insulin pump extrusion infusing pipeline structure, above-mentioned two problems are mainly solved,
Make extrusion infusing pipeline unimpeded, durable.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of insulin pump extrusion infusing pipeline structure, it includes hub assemblies and remaining needle, and hub assemblies include and indwelling
The outer needle stand of pin connection, the inside of outer needle stand offer water conservancy diversion chamber, funnelform stainless steel rivet are provided with water conservancy diversion chamber,
The non-needle end of remaining needle extends to the inside of outer needle stand and is interference fitted connection, the pin of remaining needle with the tip of stainless steel rivet
Pipe outer wall is fixed with the sealing of outer needle stand, and stainless steel rivet is hollow, and water conservancy diversion chamber and the inside of stainless steel rivet, remaining needle connect
It is logical to form infusion channel.
Wherein, in the tip insertion remaining needle of stainless steel rivet.
Wherein, end face of the tip of stainless steel rivet without departing from outer needle stand.Stainless steel rivet tip weak spot is buried as far as possible
Enter in outer needle stand, can be to avoid remaining needle broken pipe, plugging or rupture.
Particularly, the end face distance of the tip of stainless steel rivet to outer needle stand is 1.2~1.3mm.
Wherein, stainless steel rivet is stamping die tensioning member.Common plastics rivet Shooting Technique is flowed sexual factor shadow by plastic cement
Ring, rivet wall thickness cannot be too small so as to causing rivet outside diameter big, and stainless steel rivet process stabilizing, and dimension control is good and valency
Lattice are cheap.
To sum up, beneficial effects of the present invention are that compared with prior art, the insulin pump extrusion infusing pipeline structure passes through
Common plastics rivet is replaced using stainless steel rivet, effectively controls rivet sizes, the excessive swell of indwelling needle wall is avoided and becomes
It is thin, easily rupturable, in addition, controlling at the tip of the stainless steel rivet in remaining needle inside outer needle stand so that remaining needle is not easy
Broken pipe at the weak spot and influence to inject, so as to effectively control cost, improve using effect, feasibility is strong.

Embodiment
Further illustrate technical scheme below with reference to the accompanying drawings and specific embodiments.
Refer to shown in Fig. 2 and 3, the present embodiment provides a kind of insulin pump extrusion infusing pipeline structure, including hub assemblies
With remaining needle 2, hub assemblies include the outer needle stand 3 being connected with remaining needle 2, and the inside of outer needle stand 3 offers water conservancy diversion chamber, water conservancy diversion
Be provided with funnelform stainless steel rivet 1 in chamber, the non-needle end of remaining needle 2 extend to the inside of outer needle stand 3 and with it is stainless
The tip interference fit connection of steel rivet 1, the needle tubing outer wall of remaining needle 2 is fixed with the sealing of outer needle stand 3, during stainless steel rivet 1 is
Empty part, water conservancy diversion chamber connect to form infusion channel with the inside of stainless steel rivet 1, remaining needle 2.
An existing insulin pump to be connected with remaining needle 2 ' with the plastic rivet 1 ' that extrusion infusing pipeline uses, the plastic rivet
1 ' is completed by mold injection, is influenced by plastic cement flowing sexual factor, and wall thickness equidimension cannot be too thin, and specific wall thickness is 0.19mm,
A diameter of 0.9mm, the outside diameter of remaining needle 2 ' is 0.63mm, and internal diameter 0.45mm, both are interference fitted in connection procedure, cause to stay
Putting the internal diameter size of pin 2 ' can be stretched to 0.9mm, so that tube wall is thinning, easily rise brokenly, cause insulin to reveal.
Stainless steel rivet 1 in this implementation is made of punching press closing mould stretching, process stabilizing, dimension control is good and price just
Preferably, can be 0.1mm by wall thickness control, outer diameter control is 0.7mm, relative to the small 0.2mm of plastic rivet 2 ', is reduced
The deformation of remaining needle 2, and dimensionally stable, can produce in enormous quantities.
In addition, in the tip insertion remaining needle 2 of stainless steel rivet 1, and by the tip of stainless steel rivet 1 without departing from outer needle stand
3 end face is set, and the distance of tip to end face is arranged to 1.2~1.3mm and is advisable, and 1.28mm is optimized for according to practical experience,
1 tip weak spot of stainless steel rivet is embedded in needle stand, can be to avoid 2 broken pipe of remaining needle, plugging or rupture.
In conclusion the insulin pump in the present embodiment is replaced commonly with extrusion infusing pipeline structure by using stainless steel rivet
Plastic rivet, effectively controls rivet sizes, avoids the excessive swell of indwelling needle wall and thinning, easily rupturable, in addition, by remaining needle
In stainless steel rivet tip control inside outer needle stand so that remaining needle is not easy the broken pipe at the weak spot and influences to note
Penetrate, so as to effectively control cost, improve using effect, feasibility is strong.
Above example is to elaborate the basic principle and characteristic of the present invention, and the present invention limits from above-mentioned example,
Without departing from the spirit and scope, the present invention also has various changes, these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
