It is the relation between itself not indicating discussed various embodiments and/or arranging for purposes of simplicity and clarity.Additionally,
The invention provides various specific technique and material example, but those of ordinary skill in the art can be appreciated that other
The use of the applicable property and/or other materials of technique.
Syringe 100 according to embodiments of the present invention is described below with reference to Fig. 1, the syringe 100 can be used for injecting fluid,
Such as liquid, gas or gas liquid mixture.
With reference to Fig. 1, syringe 100 according to embodiments of the present invention, including:Syringe 1, pushing cylinder 2, piston 3 and corrugated tube 4.
Specifically, the rear end (rear end shown in Fig. 1) of syringe 1 is opened wide, the front end (front end shown in Fig. 1) of pushing cylinder 2 from
The rear end of syringe 1 is stretched in syringe 1, specifically, during syringe 100 is operated with, operates 2 phase of pushing cylinder
To syringe 1, (rear shown in Fig. 1) is mobile backward, and extraneous fluid can be caused to enter in syringe 100, pushing cylinder is operated
2 relative to (front shown in Fig. 1) movement forward of syringe 1, and the fluid in syringe 100 can be caused to release syringe 100.
Further, (such as on the fore-and-aft direction shown in Fig. 1) is formed with the axial direction of pushing cylinder 2 on the side wall of pushing cylinder 2
Multiple graduation marks 21 of spaced relation, the pressure of fluid in the cavity 6 that multiple graduation marks 21 intuitively can react hereinafter described
Power, so as to be operated in the pressure limit of safety in order to syringe 100 by the observation to graduation mark 21..
Specifically, piston 3 is sealed between the internal perisporium of the periphery wall and syringe 1 of pushing cylinder 2 and is connected to pushing cylinder 2, so,
The receiving space of fluid can be completely cut off by piston 3 with the space in the external world to be opened, consequently facilitating the sealing injection of fluid, and push away in promotion
During cylinder 2, piston 3 can be moved in syringe 1 with pushing cylinder 2, so as to play a part of sealing always.
With reference to Fig. 1, corrugated tube 4 is located in pushing cylinder 2, the front end (front end shown in Fig. 1) of corrugated tube 4 open wide and directly or
Person is indirectly connected to pushing cylinder 2, that is to say, that the front end of corrugated tube 4 may be connected directly to pushing cylinder 2, it is also possible to by other companies
Relay part is indirectly connected to pushing cylinder 2, rear end (rear end shown in Fig. 1) closing of corrugated tube 4 and the axial direction (figure along pushing cylinder 2
Fore-and-aft direction shown in 1) movable so that corrugated tube 4 is scalable, the Fluid pressure of the rear end of corrugated tube 4 in cavity 6
Move between multiple graduation marks 21 under effect.
Specifically, during 100 use of syringe, the rear end of corrugated tube 4 is under the Fluid pressure effect in cavity 6
Expand backward, when the pressure of fluid in resilience force and cavity 6 that corrugated tube 4 itself expansion is produced is equal, corrugated tube 4
Rear end can stop dilatancy and keep stable, and at this moment, the rear end of corrugated tube 4 can be with a certain bar scale in multiple graduation marks 21
Line 21 is flushed, so as to can quickly and easily obtain the pressure of fluid in cavity 6, the stream during injection, in cavity 6
Body pressure can change at any time, and when pressure change is big, the rear end of corrugated tube 4 can be moved rearwards by, when pressure becomes hour, corrugated tube
4 rear end can move forward, and so as to learn the pressure of fluid in cavity 6 in real time, and then quickly and easily can be noted
Penetrate and guarantee that the Fluid pressure injected, in safety range, improves processing safety.Preferably, corrugated tube 4 can be
Silica gel tube.
Syringe 100 according to embodiments of the present invention, corrugated tube 4 is under the Fluid pressure effect in cavity 6 in multiple graduation marks
Between stretch, can intuitively observe 6 fluid pressure situation of cavity, so that it is guaranteed that injection Fluid pressure in safety range,
Improve processing safety.In addition, the low cost of this syringe 100, can single use..
In some embodiments of the invention, the rear end of corrugated tube 4 in cavity 6 Fluid pressure effect under in multiple scales
Linear movement between line 21 is so that 4 linear extendible of corrugated tube, specifically, in cavity 6, the pressure of fluid is existed with corrugated tube 4
Deflection on axial direction constitutes linear relationship, for example, when pressure is two units, the deflection in the axial direction of corrugated tube 4
And two units, when pressure is three units, the deflection in the axial direction of corrugated tube 4 is also three units, so,
On the one hand it is easy to the uniform arrangement of multiple graduation marks 21, on the other hand easy-to-read display.
In some embodiments of the invention, corrugated tube 4 can be formed as conical corrugated pipe, so as to can effectively ensure ripple
Stability of the pipe 4 in dilatancy, for example, from the front end of corrugated tube 4 to the rear end of corrugated tube 4 and the axle along pushing cylinder 2
Line direction (such as the fore-and-aft direction shown in Fig. 1), the cross-sectional area of corrugated tube 4 is gradually reduced, so as in the swollen of corrugated tube 4
During bulging deformation, the portion that the big part of the cross-sectional area of 4 leading section of corrugated tube can be little to the cross-sectional area of 4 rearward end of corrugated tube
Certain supporting role point is played, and then ensures stability of the corrugated tube 4 in dilatancy, the phenomenon such as do not shift.
In some embodiments of the invention, with reference to Fig. 1, corrugated tube 4 is coaxially disposed with pushing cylinder 2, that is to say, that corrugated tube
4 central axis is same straight line with the central axis of pushing cylinder 2, consequently facilitating the installation of corrugated tube 4 and pushing cylinder 2, and it is swollen
Swollen effect is more preferable.
In some embodiments of the invention, the front end of corrugated tube 4 is indirectly connected to pushing cylinder 2 by non-telescoping connecting tube 5,
Specifically, with reference to Fig. 1, the front end of connecting tube 5 is connected with the front end of pushing cylinder 2, front end and the connecting tube 5 of corrugated tube 4
Rear end be connected, so as on the one hand ensure the sealing of cavity 6, be on the other hand easy to the mounting stability of corrugated tube 4.
Specifically, connecting tube 5 includes the first pipeline section 51, the second pipeline section 52 and is serially connected in the first pipeline section 51 and the second pipeline section
Transitional pipe segment 53 between 52, the front end of the first pipeline section 51 are connected to the front end of pushing cylinder 2, the rear end connection of the second pipeline section 52
To the front end of corrugated tube 4, so as to further improve the sealing of cavity 6, and it is easy to the conducting of fluid.
Further, with reference to Fig. 1, from the front end of transitional pipe segment 53 to rear end and along the axis direction (shown in Fig. 1 of pushing cylinder 2
Fore-and-aft direction), on the one hand the cross-sectional area of transitional pipe segment 53 is gradually reduced, and so, is further easy to the conducting of fluid,
On the other hand it is easy to the installation of corrugated tube 4.
Further, with reference to Fig. 1, the first pipeline section 51 and the second pipeline section 52 are equal diameter pipe, and the first pipeline section 51 is straight
Diameter of the footpath more than the second pipeline section 52, so, is on the one hand further easy to the conducting of fluid, is on the other hand easy to connecting tube 5
