Description
Technical field
The utility model relates to medical instruments field, in particular to a kind of disposable antireflux double end injects connecting tube.
Background technique
At this stage, many medical scenes need while using multiple groups syringe, instrument most frequently used at present
It is injection connecting tube, injection connecting tube is generally two or more drug-feeding tubes, a drug discharging tube, can be two in use process
Or multiple drug-feeding tubes inject input simultaneously, can also individually drug-feeding tube injection input, can be replaced with two or more drug-feeding tubes
Multiple injection input.
But can be generated in some input processes medical fluid backflow even some cases will appear drug mixing, clinic is controlled
It treats and generates large effect.Connection tube shape is relatively fixed mostly, and in clinical process, different sufferers and different scenes can be generated
It is inconvenient for use, biggish injection resistance is had there are also some connecting tubes, vortex is generated in injection process, influences therapeutic effect.
Summary of the invention
In order to make up for the deficiencies of the prior art, it is simple to provide a kind of structure, easy to use, safety and sanitation for the utility model
Disposable antireflux double end inject connecting tube.
The utility model is achieved by the following technical solution:
A kind of disposable antireflux double end injection connecting tube, including connection tube body, connection tube body lower end are provided with out
Pencil, drug discharging tube top are provided with drug-feeding tube A and drug-feeding tube B, and drug discharging tube bottom end is provided with needle hub, drug discharging tube lower side
It is provided with screw thread mouth, drug-feeding tube A and drug-feeding tube B and drug discharging tube junction is internally provided with antireflux device, needle hub is used to
Connecting needle is later fixed syringe needle using screw thread mouth, prevents syringe needle landing from causing danger.
The disposable antireflux double end of the utility model injects connecting tube, and the drug-feeding tube A and the top drug-feeding tube B are respectively mounted
There is syringe adapter, syringe adapter is used to connect disposable syringe.
The disposable antireflux double end of the utility model injects connecting tube, and angle is between the drug-feeding tube A and drug-feeding tube B
60 °, 60 ° of angles can guarantee it is more convenient to use and more convenient in the narrow positions puncture and injection of medicine such as neck, compared to
90 ° of angles or more low-angle can guarantee smaller injection resistance, be not likely to produce vortex.
The disposable antireflux double end of the utility model injects connecting tube, and the antireflux device is liquid non-return valve, single
It can guarantee that medical fluid can only flow into drug discharging tube by drug-feeding tube to valve, prevent the drug in drug discharging tube from backflowing and medical fluid is carried out
Pollution.
The disposable antireflux double end of the utility model injects connecting tube, and the diameter of the needle hub is less than drug discharging tube
Diameter, the diameter of syringe adapter are greater than the diameter of drug-feeding tube A and drug-feeding tube B.
The disposable antireflux double end of the utility model injects connecting tube, and the drug-feeding tube A and drug-feeding tube B stretch for multisection type
Shrinking structure, Multi-section expansion structure can possess more selections in different clinical settings, can be by adjusting drug-feeding tube
Length selects injection angles the most suitable and environment.
The beneficial effects of the utility model are:
The disposable antireflux double end of the utility model injects connecting tube, can two drug-feeding tubes inject input simultaneously,
It can individually drug-feeding tube injection input, it can be with two drug-feeding tubes alternating multiple injections inputs；And it is provided with antireflux device,
Liquid medicine contamination can be prevented, also adjustable proper angle, prevent injection vortex；It is additionally provided with scalable drug-feeding tube,
More more options are brought for different clinical settings, structure is simple, easy to use.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 drug-feeding tube A；2 drug discharging tubes；3 syringe adapters；4 antireflux devices；5 screw thread mouths；6 needle hubs；7 into medicine
Pipe B；8 connection tube bodies.
Specific embodiment
Attached drawing is a kind of specific embodiment of the utility model.The embodiment includes connection tube body 8, connects tube body 8
Lower end is provided with drug discharging tube 2, and 2 top of drug discharging tube is provided with drug-feeding tube A1 and drug-feeding tube B7, and 2 bottom end of drug discharging tube is provided with syringe needle and connects
Mouth 6,2 lower side of drug discharging tube is provided with screw thread mouth 5, drug-feeding tube A1 and drug-feeding tube B7 and is internally provided with 2 junction of drug discharging tube
Antireflux device 4, drug-feeding tube A1 and the top drug-feeding tube B7 are mounted on syringe adapter 3, between drug-feeding tube A1 and drug-feeding tube B7
Angle is 60 °, and antireflux device 4 is liquid non-return valve, and the diameter of needle hub 6 is less than the diameter of drug discharging tube 2, syringe adapter
3 diameter is greater than the diameter of drug-feeding tube A1 and drug-feeding tube B7, and drug-feeding tube A1 and drug-feeding tube B7 are Multi-section expansion structure.
In use, needle hub 6 is connected syringe needle and syringe needle is fixed using screw thread mouth 5, using drug-feeding tube A1 and
The upper disposable syringe of the connection of syringe adapter 3 on drug-feeding tube B7, adjusting drug-feeding tube A1 and drug-feeding tube B7 to appropriate length, it
Afterwards, can two drug-feeding tubes inject input simultaneously, can also single drug-feeding tube injection input, can be more with two drug-feeding tubes alternatings
Secondary injection input, in input process, medical fluid flows into drug discharging tube 2 by drug-feeding tube A1 and drug-feeding tube B7, and antireflux device 4 can be kept away
The medical fluid reflux exempted from drug discharging tube 2 enters in drug-feeding tube A1 and drug-feeding tube B7, avoids liquid medicine contamination.
