Description
Technical field
The utility model is related to area of medical devices, especially a kind of infusion twin flue remaining needle.
Background technology
To meet treatment needs and reducing patient suffering, it is logical that a remaining needle often connects two or more infusions
Road, often connect in the extension tube of existing remaining needle threeway connect respectively again in infusion channel or practical operation directly from
Remaining needle calparine cap connects two infusion channels, to meet the needs of infusion simultaneously.
Operatively there are some potential safety problemss for existing above-mentioned remaining needle.Since two infusion channels pass through threeway
It keeps that two scalp acupunctures are inserted directly into calparine cap in connection or practical operation, the infusion velocity of two groups of drugs often differs
Sample is likely to occur one group of liquid in infusion process and backflows the problem of flowing to another infusion channel.Moreover, the drug of two channels
It is transfused by same pipeline, there are the risks of compatibility of drugs reaction.
Utility model content
The utility model provides a kind of twin flue remaining needle, solves two infusion channels during existing remaining needle use
It interconnects, there are problems that some potential safety problems.
Technical solution is used by the utility model solves its technical problem：Twin flue remaining needle including needle stand and is worn
Pricker, needle stand are made of transparent material, and one end of needle stand is indwelling hose, and main pipeline and time pipeline are set in indwelling hose, main
The cross-sectional area of pipeline is more than the cross-sectional area of time pipeline, and the outlet of main pipeline is located at the end point of indwelling hose, secondary pipeline
Outlet is positioned at the side of the end of indwelling hose；
Needle cavity is formed in needle stand, needle cavity is connected with main pipeline, and setting batching pig in needle cavity, one end of puncture needle passes through isolation
It fills in and is inserted into main pipeline, the other end connecting puncture needle seat of puncture needle connects single-blade needle handle on Paracentesis needle holder；
Extension tube is connected on needle stand, mutually independent two pipelines, one of pipeline one end and needle are set in extension tube
Chamber connects, and the other end connects the first branch pipe；Another pipeline one end is connected through needle stand with time pipeline, and the other end connects second
The end of pipe, the first branch pipe and the second branch pipe is all connected with infusion connector, and switch is set respectively on the first branch pipe and the second branch pipe.
Specifically：The switch is flow-stopping clip.
The beneficial effects of the utility model are：Twin flue remaining needle can respectively be carried out by the first branch pipe or the second branch pipe
Infusion, can also be used as dosing branch pipe.Two infusion channels may be connected directly to blood vessel, completely independent from one another, individually control, mutually
It does not influence, avoids the problem that one group of liquid backflows and flow to another infusion channel, two groups of drugs is also avoided to be mixed in infusion channel
The problem of, it ensure that infusion efficiency, improve infusion safety.
Description of the drawings
Fig. 1 is the structure diagram of the utility model twin flue remaining needle.
Fig. 2 is the partial enlarged view of a-quadrant in Fig. 1.
Parts, position and number in figure：Needle stand 1, needle cavity 11, puncture needle 2, Paracentesis needle holder 21, single-blade needle handle 22, indwelling

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, the utility model twin flue remaining needle, including needle stand 1 and puncture needle 2, needle stand 1 is transparent modeling
Material is made, and one end of needle stand 1 is indwelling hose 3, if the left side of Fig. 1 is indwelling hose 3.Setting main pipeline 31 in indwelling hose 3
With secondary pipeline 32, main pipeline 31 does not connect independently of one another with time pipeline 32, and the cross-sectional area of main pipeline 31 is more than time pipeline 32
Cross-sectional area, the outlet of main pipeline 31 is positioned at the end point of indwelling hose 3, and the outlet of secondary pipeline 32 is positioned at the end of indwelling hose 3
The side of head.
Needle cavity 11 is formed in needle stand 1, needle cavity 11 is connected with main pipeline 31, and needle cavity 11 is not connected with secondary pipeline 32.Needle cavity 11
Interior setting batching pig 4, one end of puncture needle 2 pass through batching pig 4 and are inserted into main pipeline 31, and the other end connection of puncture needle 2 is worn
Pricker seat 21, connection single-blade needle handle 22 on Paracentesis needle holder 21.Multiple anti-skid bulges are set on single-blade needle handle 22.Connect indwelling hose
Needle stand 1 at 3 has guiding role to puncture needle 2, ensures that puncture needle 2 is penetrated in the main pipeline 31 of indwelling hose 3.Such as Fig. 2 institutes
