Preferably, the retaining needle flexible tube is transparent soft catheter.
The straight type remaining needle of operation for implementing the utility model, has the advantages that：Remaining needle is used during surgery
It, need not be by tight patient's arteriovenous when puncturing or changing liquid, it will be able to realize operation quickly, safe, and effective anti-return blood
The phenomenon that causing cannula end to block；In addition the utility model it is of simple structure and low cost, it is highly practical, be conducive to push away extensively
Wide application.
Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model indwelling needle and retaining needle flexible tube；
Fig. 2 is the structural schematic diagram that the utility model indwelling needle and Paracentesis needle holder combine；
Fig. 3 is the structural schematic diagram of the utility model flexible sheet；
Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate the specific implementation mode of the present invention.
As shown in Figure 1, in the straight type remaining needle of operation described in the utility model, including hollow indwelling needle 1 and
The retaining needle flexible tube 2 being arranged on indwelling needle, the side of indwelling needle be equipped with dosing mouth 3, with the retaining needle flexible tube phase
To side be equipped with filling opening 12；There is dosing interface 4 on dosing mouth 3, check valve is respectively set in filling opening 12 and dosing interface 4
Structure 5；It is connected to sealing cap 10 at dosing interface 4, the folding double-vane 11 with hole is additionally provided on indwelling needle 1.
The one-way valve structures 5 are various informative, such as have spring：Liquid from bottom to top, by pressure jacks up spring control
The flap of system, after pressure disappears, spring force depresses flap, and sealing liquid is flow backwards；Gravity type：It is sealed by its own gravity of flap
It closes, prevents from flowing backwards；Swing type：Liquid is led directly in valve body, by the rotation flap of the open-top side of pressure, after pressure loses, valve
Valve closes flap by dead weight return, reversed fluid pressure；Plastic partition membrane type:Shell and diaphragm are that plastics shells are
ABS, PE, PP, NYLON, PC. diaphragm have silicones, fluororesin.The one-way valve structures 5 set up in filling opening 12 are with forward direction
Under the action of hydraulic pressure, flow rate of liquid is smooth, does not influence normally infusion or transfusion speed.
As shown in figure 3, in some embodiments of the utility model, one-way valve structures 5 include medical flexible sheet 51,
Can be the medicine commonly similar structures such as flexible sealing-plug, rubber ring；Flexible sheet 51 is equipped in positive pressure
The micropore 511 of lower opening；Positive pressure or hydraulic pressure are applied to flexible sheet 51 by needle tubing when use, micropore is forced to be opened
It is punctured or is infused, after needle tubing is extracted or without under hydraulic action, the flexible sheet can restore to the original state rapidly, be closed micro-
Any trace is not stayed in hole, that is to say, that blood will not flow back into indwelling needle inner cavity from micropore.Complete retained needle puncture process
Afterwards, screw thread cap closure filling opening 12 can also can be used by 12 external infusion of filling opening.In addition, can be according to infusion type, also
Uniline channel in flexible sheet 51 can be replaced with to lateral microcrack or " cross " crack.
As shown in Fig. 2, indwelling needle 1 is hollow structure, one end is connect with retaining needle flexible tube 2, other end connecting puncture needle
Seat 7.Puncture needle 6 can be inserted into from Paracentesis needle holder 7, and retaining needle flexible tube 2 is pierced by by indwelling needle 1；In 7 outside wall surface of Paracentesis needle holder
One hand handle 8 is set, and hand handle 8 is long flat shape, and convenient hand-held Paracentesis needle holder 7 carries out puncture procedure.In addition 7 other end of Paracentesis needle holder
It is provided with thread cap 9, the thread cap can not only be connect with 7 spiral of Paracentesis needle holder, while can also be connected with indwelling needle 1
It connects, closes indwelling needle 1 and contacting external air.
During surgery, it is inserted into human body using the syringe needle of puncture needle 6, blood back is seen by transparent retaining needle flexible tube 2, to
Intravascular to judge to puncture entrance, then extraction puncture needle 6 while retaining needle flexible tube 2 are completely fed to intravascular, you can by indwelling
Needle is retained on human body, then by the external infusion (blood) of filling opening 12 and (blood) speed of being infused is not by the shadow of one-way valve structures 5
It rings, has been infused and has closed indwelling needle with thread cap 9, when needing dosing, can directly open sealing cap 10, carry out feeding operations.
It should be understood that above example only expresses preferred embodiments of the present invention, description is more specific
