Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-Fig. 9 is refer to, the present embodiment provides a kind of drainage needle 100, including syringe 110, the valve being sequentially connected
120th, syringe needle 130.In the present embodiment, syringe 110 is conventional specification, and capacity is 50~100 milliliters.In the range of capacity,
The amount of conventional breast puncture injecting normal saline can be met.In other embodiments of the invention, syringe 110 can be other
Specification, the present invention is not limited it.
Fig. 2 is refer to, in the present embodiment, valve 120 is three-way valve 120.Valve 120 includes valve body 121, knob
123rd, locating part 125.Valve body 121 includes first-class road junction 1211, second road junction 1213 and third flow channel mouthful 1215, syringe
110 dispensing end is connected with first-class road junction 1211, and the fixing end of syringe needle 130 is connected with second road junction 1213.
Specifically, syringe needle 130 includes needle body 131 and puncture needle 132, needle body 131 is interconnected with puncture needle 132, needle body
The end of 131 remote puncture needle 132 bends inwards to form the first flange 133, and the first flange 133 is annular, the first flange 133
Two the first breach 134 are provided with, the inwall at second road junction 1213 is provided with the fixture block 127 coordinated with the first breach 134, card
Block 127 is slipped into needle body 131 from the first breach 134 in the rotary course of syringe needle 130 and blocked in syringe needle 130 continues rotary course
Tight first flange 134.
So design and be advantageous in that syringe needle without departing from second road junction 1213, this design can ensure to be taken out in vomica
Purulence is taken out in vacuum realization that can be rapidly and efficiently higher always after vacuum, if not using this to design, and syringe needle 130 is from second road junction
1213 come off, and air reenters vomica, and it is highly difficult for now vomica being vacuumized again, because first time puncture needle
132 can be perforated when entering vomica on vomica film, be vacuumized if entering eleven punch 11 for the second time, and the hole that perforation is formed for the first time is deposited all the time
It can cause to vacuumize failure, it is necessary to wait vomica film to carry out taking out purulence after restoring again.
Width of the fixture block 127 in the circumference along second road junction 1213 is unequal, and fixture block 127 width from first-class
It is gradually reduced on road junction 1211 to the direction of second road junction 1213, the width of the first breach 134 is more than close the first of fixture block 127
The width of the end of runner mouthful 1211.Contraposition of the syringe needle when being connected with valve 120 can so be facilitated.
Third flow channel mouthful 1215 is used to connect negative pressure device, and negative pressure device is, for example, minipump.Negative pressure device is in valve
Door 120 is switched to when first-class road junction 1211 is connected with third flow channel mouthful 1215 and connected with puncture needle 132.As it was previously stated, negative pressure
Device operationally must assure that and will not fall off, therefore, in the present embodiment:
The inwall of third flow channel mouthful 1215 is provided with latch 129, the end being connected with third flow channel mouthful 1215 of negative pressure device
Portion bends inwards to form the second flange 135, and the second flange 135 is annular, and the second flange 135 is provided with two and matched somebody with somebody with latch 129
The second breach closed.
Width of the latch 129 in the circumference along third flow channel mouthfuls 1215 is unequal, and latch 129 width from close to the
First-class direction one end of road junction 1211 is gradually reduced to away from first-class direction one end of road junction 1211, and the width of the second breach is more than card
The width of the end at the close first-class road junction 1211 of tooth 129.
Fig. 2 and Fig. 3 is refer to, knob 123 controls first-class road junction 1211, second road junction 1213 and third flow channel mouthful
Connection between 1215, and then the working condition of control valve 120.In the present embodiment, valve 120 provided with off working state,
First working condition and the second working condition.When drainage needle 100 is off working state, knob 123 controls first-class road junction
1211st, second road junction 1213 and third flow channel mouthful 1215 are connected;When drainage needle 100 is the first working condition, knob 123
Control first-class road junction 1211 to be connected with second road junction 1213, close third flow channel mouthful 1215, i.e., only syringe needle 130 passes through valve
120 connect with syringe 110;When drainage needle 100 is the second working condition, the control second of knob 123 road junction 1213 and the 3rd
Runner mouthful 1215 is connected, and is closed first-class road junction 1211, i.e. syringe needle 130 and is connected with third channel mouthful, but does not connect with syringe 110
It is logical.
In the present embodiment, the axis side at first-class road junction 1211, second road junction 1213 and third flow channel mouth 1215
To being mutually perpendicular to, knob 123 includes three rotating handles 1231, and the length direction of three rotating handles 1231 is mutually perpendicular to.Rotate
The direction of handle 1231 is identical with the communication direction of valve 120, and the direction by rotating handle 1231 is that can determine whether the work of valve 120
State, while being easy to be operated as needed, prevents maloperation, influence treatment.In other embodiments of the invention, knob
123 rotating handle 1231 can be other shapes and structure, such as quadrangle, each angle correspondence circulating direction, the present invention to it not
Limit.
Fig. 4 is refer to, in actual therapeutic process, the liquid full of flowing in valve 120, the liquid of flowing is to valve
120 valve body 121 and first-class road junction 1211, second road junction 1213 and third flow channel mouthful 1215 application active forces, at this
Under active force, knob 123 is easily rotated, and influences the flowing of liquid, and influences therapeutic effect.In order to stablize knob 123, valve
120 include locating part 125.Locating part 125 is arranged at knob 123, limits the rotation of knob 123, and locating part 125 is arranged at described
Knob 123 is contacted so as to be damped between the knob 123 and the outer wall of the valve.
In order to more accurately arrive at lesions position, in the present embodiment, the outer surface of puncture needle 132 is provided with scale (figure
Do not show).The position of focus according to early stage testing result, can be learnt and the distance of puncture is needed, accurate treatment is reached, shortening is controlled
The treatment time, reduce the pain of sufferer.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
