Description

A kind of binary channels beauty injector for medical purpose

Technical field

The utility model belongs to shaping medical instruments field, and in particular to a kind of binary channels beauty injector for medical purpose.

Background technology

In medical shaping field, often need some fillers（Such as sodium hyaluronate）Human body privileged site is injected into, in order to Ensure the safe and postoperative effect of surgical procedure, in injection fillers object, need to prevent from injecting syringe needle in blood vessel, this is because Once filler enters blood vessel, general blood vessel embolism, heavy then threat to life are gently then caused.

Syringe needle is inserted into happening for blood vessel in order to prevent, and doctor is not only needed to have preferable technical merit, also needs to have There are higher advanced surgical instrument, particularly syringe.

In general, existing beauty injector for medical purpose is mostly single needle single channel syringe.It in use, need to be to syringe Pumpback is carried out, whether blood vessel is inserted into examination.But, in real work, after inserting the needle into human body, due to group around needle point Knit it is closeer, when oozing of blood is less, to conventional needle carry out pumpback, it is difficult to obtain can by blood pumpback come out pressure difference.

Single channel syringe needle is different from, some research institutions have carried out syringe needle the research of other structures syringe.Northwest woman Female children's hospital proposes a kind of Dual pipe dual passage needle and syringe head（See 205515814 U of CN）, it is provided in needle tubing Two independent cavitys carry out pumpback with one of cavity, another cavity is filled the injection of object.However, the note Emitter still has shortcoming：（1）, although it provides a cavity and is individually used for the pumpback of blood, but still can not solve blood The problem of liquid pumpback is difficult；（2）Blood is easily introduced filler cavity by the syringe construction, is caused to being equipped with filler cavity Pollution.

Therefore, this field still needs to research and develop a kind of better beauty injector for medical purpose.

Utility model content

The purpose of this utility model is that providing a kind of binary channels beauty injector for medical purpose in view of the shortcomings of the prior art, wrap Syringe needle and injection-tube are included, the syringe needle is connected with injection-tube by the first connector, and the first valve is set on the first connector；Syringe needle The second connector is equipped with, voltage indicating device is connected by the second connector with syringe needle, and the second valve is set on the second connector；It is soft One end of property conduit is fixed on the second connector, and the other end extends needle point along syringe needle；The injection-tube be equipped with first piston and First piston handle；The voltage indicating device is equipped with second piston and second piston handle；When first unclosed valve closes, syringe needle and note Penetrate pipe connection；When second unclosed valve closes, flexible conduit is connected with voltage indicating device.

Preferably, the 3rd connector, the second connector and the 3rd connector are also set up on the second connector It is connected by conduit；Cleaning liquid storing bag is connected with the 3rd connector.

Optionally, first connector, the second connector and with the 3rd connector be screw connection structure.

Preferably, the outer diameter of the syringe needle is 0.4mm, internal diameter 0.25mm.

Preferably, second connector, which is arranged on syringe needle, is no more than from the first connector at 2cm.

Compared with the prior art, the advantages of the utility model：

（1）The utility model is realized mutual indepedent between blood pumpback and filler injection by setting binary channels It carries out；Meanwhile the design of the utility model can prevent the blood of pumpback from entering the pollution that injection-tube causes filler；

（2）Flexible conduit in the utility model extends needle tip, and when needle point is inserted into blood vessel, the cavity at needle point can Enough spaces are provided for the flexible conduit at this so that in pumpback blood, it is difficult will not to lead to the problem of pumpback；Together When, flexible conduit does not influence the injection of filler；

（3）The utility model can also set cleaning liquid storing bag, and the remained blood in flexible conduit can be washed, It is easy to use.

Specific embodiment

Below against attached drawing, by the description of the optimum embodiment to the utility model, to the specific reality of the utility model The mode of applying is described in detail.

As shown in Figure 1, a kind of binary channels beauty injector for medical purpose of the utility model, including syringe needle 1 and injection-tube 2, institute It states syringe needle 1 and injection-tube 2 to be connected by the first connector 11, the first valve 13 is set on first connector 11；Syringe needle 1 is equipped with the Two connectors 10, voltage indicating device 5 are connected by the second connector 10 with syringe needle 1, and the second valve 14 is set on the second connector 10； One end of flexible conduit 9 is fixed on the second connector 10, and the other end extends needle point along syringe needle 1；The injection-tube 2 is equipped with first Piston 3 and first piston handle 4；The voltage indicating device 5 is equipped with second piston 6 and second piston handle 7；First valve 13 does not close When closing, syringe needle 1 is connected with injection-tube 2；When second valve 14 is not turned off, flexible conduit 9 is connected with voltage indicating device 5.

The 3rd connector 12 is also set up on the second connector 10, the second connector 10 is with the 3rd connector 12 by leading Pipe connects；Cleaning liquid storing bag 8 is connected with the 3rd connector 12.

First connector 11, the second connector 10 and with the 3rd connector 12 be screw connection structure.
