Abstract

The utility model relates to a tubular product rule connector, including rule male joint with rather than matched with rule female joint, characterized in that: male joint core in rule is pegged graft and is held the internal diameter to equal rather than the internal diameter of output internal diameter and connecting line, rule male joint core axial inclination and inclinations such as rule female joint grafting portion axial inclination is. The advantage is: the liquid flow that not only can increase rule male joint output is said all, has avoided forming torrent influence dialysis effect because of the liquid flow resistance sharply increases, but also can guarantee connector both ends rate of flow of fluid the stability, easily peg graft and does not take place to pollute.

Description

Tubing luer connector

Technical field

This utility model belongs to technical field of medical instruments, particularly relates to a kind of tubing luer connector.

Background technology

At present, female Luer uses widely on medical equipment, is used for pressure extension tube or the less occasion of flow velocity, but internal diameter size is generally: between 1-2.5mm.And only Rule (F) common on dialyser, rarely have Rule (F) matched both at home and abroad.It is far smaller than the design deficiency of its outfan internal diameter size (more than 30%) owing to existing clinical dialysis device also exists Rule (M) core inserted terminal internal diameter size, therefore after very easily causing pipeline to pass through this position, occur that liquid flowing resistance sharply increases the situation forming turbulent flow, it is impossible to ensure the steady of rate of flow of fluid.Especially, when needing on platform in art and under platform, two isometrical or that different diameters is little tubing connect, traditional way is to use joint grafting.And the design of grafting joint insertion portion diameter dimension is not revealed after being based on joint and tubing grafting, so splicing position diameter is greater than pipe internal diameter, therefore in art, grafting is comparatively difficult, and then very easily occur to pollute because of the touching of overexert hands and joint end face during grafting, cause postoperative inflammatory reaction.

Summary of the invention

This utility model provides a kind of simple in construction and can avoid sharply increasing the tubing luer connector forming Turbulent Flow Effects dialysis-effect because of liquid flowing resistance for solving the technical problem of existence in known technology.

This utility model is adopted the technical scheme that by the technical problem solving to exist in known technology:

Tubing luer connector, including Rule male joint and Rule female joint of being matched therewith, it is characterized in that: described Rule male joint core inserted terminal internal diameter is equal with the internal diameter of its outfan internal diameter and connecting line, described Rule male joint core axial slope and female joint Plug Division, Rule axial slope such as are at the gradient.

This utility model can also adopt the following technical scheme that

Described Rule male joint grafting core axial slope and female joint Plug Division, Rule axial slope are 6%.

This utility model has the advantage that and has the benefit effect that owing to this utility model adopts technique scheme, described Rule male joint core inserted terminal internal diameter is equal with the internal diameter of its outfan internal diameter and connecting line, the gradients such as described Rule male joint core axial slope and female joint Plug Division, Rule axial slope are, so not only can increase the fluid flow paths of Rule male joint outfan, it is to avoid sharply increase formation Turbulent Flow Effects dialysis-effect because of liquid flowing resistance；And also ensure that stablizing of adapter two ends rate of flow of fluid, it is easy to grafting and avoid polluting.

Detailed description of the invention

For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:

Refer to Fig. 1, tubing luer connector, including Rule male joint 2 and Rule female joint 1 being matched therewith, the internal diameter of described Rule male joint core inserted terminal 2-1 is equal with the internal diameter of the internal diameter of its outfan 2-2 and connecting line, and described Rule male joint core 2-3 axial slope and female joint Plug Division, Rule 1-1 axial slope such as are at the gradient.

In the present embodiment, described Rule male joint core axial slope and female joint Plug Division, Rule axial slope are 6%.

The diameter of Rule described in the utility model male joint and Rule female joint can set according to the diameter of connecting line.

The embodiment that this utility model accompanying drawing describes is illustrative of, and is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.

During Clinical practice, preoperative need to by this adapter connector insert end connect with two arts need be connected two tubing respectively.Adapter Rule M core end only need to be inserted Rule F by art screw along hand of spiral and can complete to connect.
