Description
Technical field
The present invention is on a kind of medical implements, particularly relates to a kind of safe infusion without using sharp needle and connects
Head.
Background technology
In medical treatment often using various infusion pipelines come to for sufferer input or export various liquid, such as have an intravenous drip,
Adding medicine, or blood drawing etc..Infusion connector be for being connected with various infusion pipelines, using as liquid input or export when
Valve.Increasingly increase especially as the attention for healthcare givers's security, the safety of sharp needle need not be used during use
Infusion connector has been used by many medical institutions in recent years.
But there is considerable space in existing safe infusion joint, after transfusion terminates, body fluid or medicament may be residual
Stay in these spaces, when infusing again next time, the liquid of these residuals may mix with the liquid newly added, may cause disease
The problem of bacterium infects, therefore have and be developed for reducing the safe infusion joint of residual.
No. 378806 Patent Cases of TaiWan, China I are referred to, the safe infusion joint that tradition can reduce residual includes tool
There are a shell, a feather valve and a two-way admittance element.The shell has two openings, and the feather valve is placed in the shell simultaneously
Two opening is sealed, the feather valve encloses structure and goes out the accommodation space rest two-way admittance element.Have in the two-way admittance element
One infusion channel.In use, the feather valve is pushed and deformed by external lug so that the two-way admittance element struts the elasticity
Valve, while the infusion channel communicates with two openings.After terminating, liquid can be only remained in the infusion channel without remaining
Between shell and feather valve.
The safe infusion joint of aforementioned conventional, though improve liquid residue, the two-way admittance element is only by this
Feather valve support positioning.The feather valve all needs to be extruded deformation when each use, it is contemplated that easily elastic after long-term use of
Relaxation, in turn results in that the two-way admittance position of components is unstable, and the situation for seepage occur occurs.
From the above situation, traditional safe infusion joint still there is a need to improve part.
The content of the invention
It is a primary object of the present invention to provide a kind of safe infusion joint, it can reduce liquid residue, and Stability Analysis of Structures.

Wherein first top 26 is resisted against the seal 70 and second end wall 43, and second protuberance 32 passes through should
3rd perforation 72, and such second perforation 323 is placed in the second channel 461, the first flow 225, second flow channel 325 are with being somebody's turn to do
Second channel 461 communicates.In the preferred embodiment, the free end 321 of second protuberance 32 into it is cone-shaped and with one the
Two side faces 327, second perforation 323 are opened in the second side 327.
Next the use state of the explanation present invention.
See Fig. 6, Fig. 7, when user is intended to infuse via the safe infusion joint 10, by a syringe mouth of pipe (in figure not
Show) to fill in first ring wall 45, first elastic component 50 interlocks second inner tube 30 and moved towards second ring wall 46, this
When, such first perforation 223 of the first inner tube 20 no longer by the masking of first elastic component 50, in syringe with first flow 225,
Second flow channel 325 and second channel 461 communicate, and allow user can infusion fluid, or extract liquid out on demand.Meanwhile this second
Two connecting portions 66 of elastic component 60 are elongated.
It should be noted that during transfusion, only the second inner tube 30 can be promoted, and the first of first inner tube 20 supports
Portion 26 is resisted against second end wall 43 and motionless, therefore structure quite stable.In addition, liquid only can be in the first flow 225,
Flow, will not be leaked into first accommodation space 44 between two runners 325 and the second channel 461, thus reduce liquid
Residual quantity.Gap between second protuberance 32 and second end wall 43 is sealed by the seal 70, and make will not at this
Seepage, in other possible embodiments, the seal 70 is not limited to sheet, but the seal 70 is attached at second end wall 43
And supported by first top 26, the safe infusion joint 10 without the seal 70 can also reach the purpose of the present invention,
Now, second perforation 323 of second protuberance 32 is contained directly in the second channel 461, the first flow 225, second
Runner 325 communicates with the second channel 461.
When user is intended to terminate transfusion, it is only necessary to take out the syringe mouth of pipe from first ring wall 45, then second inner tube
The 30 such connecting portions 66 that can be elongated draw and resetted towards the direction of first ring wall 45, while first elastic component 50
The position for returning to script is driven by second top 36, i.e. the head 52 of first elastic component 50 is again sealed off the first passage
451。
In order to more increase the effect of antiseep, first elastic component 50 also there is a neck 54 to connect the head 52 and the body
Portion 56, the direction of the external diameter and internal diameter of the neck 54 from the head 52 toward the body portion 56 gradually expand, first protuberance 22
In cone-shaped and have a first side 227, this first is perforated and 223 is opened in the first side 227 for free end 221, and this
The intersection of one end wall 42 and first ring wall 45 also has a pressure section 48, the pressure section 48, the neck 54 and first side
Face 227 accordingly coordinates so that the pressure section 48 compresses the neck 54 and the first side 227, such first perforation of increase sealing
223 effect.Furthermore the free end 321 of second protuberance 32, into cone-shaped and have a second side 327, this second is worn
Hole 323 is opened in the second side 327.
In order that structure is more stable, between the fit portion 24 of first inner tube 20 and the trunk 34 of second inner tube 30 also
With an elastic band 80 so that the first flow 225 can be tightly engaged with the second flow channel 325.
In order that the gearing between first elastic component 50 and second inner tube 30 is more certain, the body of first elastic component 50
Portion 56 also has a locating slot 562, and the free end of second top 36 also has a flange 361, the flange 361 and the positioning
Groove 562 engages.
It should be noted that, the above coordinates the detailed description carried out by accompanying drawing herein, merely to the technology of the explanation present invention
Content and feature and the embodiment provided, the those of ordinary skill of all technical fields in the present invention, understanding the present invention
Technology contents and feature after, under the spirit without prejudice to the present invention, a variety of simple modifications for being done, replace or component
