Slided along the linear pattern passage；The first space that first plug and the second plug are limited is used to accommodate liquaemin；Described
Second side of two plugs is provided with screw rod；The first end of screw rod is fixed on the center of the second side of the second plug；The second of screw rod
End is fixed with rotary block；Screw rod perforation is formed with the middle part of piston handle, screw rod perforation inner side is formed with engages with the screw rod
Screw thread；Second end of the screw rod is perforated via the screw rod extends to the outside of piston handle so that rotary block is located at
The outside of piston handle；
The piston head is contained in the body, and the body has delivery outlet in its first end, and physiological saline is accommodated
In the second space limited between delivery outlet and piston head；Second end of the body is formed with rod aperture, the piston
Bar is extended through outside body from the rod aperture.
Preferably, it is formed further with cue mark on the body.
Preferably, the minimum diameter of first plug is more than the maximum gauge of the delivery outlet of the body.
The pre- formula tube sealing syringe that rushes of the present utility model can complete to rinse and tube sealing operation by a syringe, and
Physiological saline isolates preservation with liquaemin, and tube-sealing solution situ configuration is very convenient to use, without using two syringes,
And can preserve for a long time, that is to say, that it can produce for a long time in advance.Further, since approach screw promotes liquaemin, make
Obtain in not rotary screw, the position of the second plug and piston head is stable, will not be moved rearwards by by the reaction of liquid.

Embodiment
Below, the pre- formula tube sealing syringe that rushes of the present utility model is described in detail with reference to accompanying drawing.
It is of the present utility model it is pre- rush formula tube sealing syringe, it includes body 20, piston apparatus 10.
Piston apparatus 10 includes：Piston head 16, piston rod, piston handle 12.
Piston head 16 is fixedly mounted in the first end of piston rod, and piston handle 12 is fixedly formed in the second of piston rod
End.
Linear pattern passage 15 is formed with through piston head 16 and piston rod.Linear pattern passage 15 first end removably
And it is fluid tight be provided with the first plug 17, the second plug 14 is provided with fluid tightly in linear pattern passage 15, in outer masterpiece
It can be slided with lower second plug 14 along linear pattern passage 15.The first space that first plug 17 is limited with the second plug 14 is used for
Accommodate liquaemin.Second side of the second plug 14 is provided with screw rod 13.The first end of screw rod 13 is fixed on the of the second plug 14
The center of two sides.Second end of screw rod 13 is fixed with rotary block 11.The middle part of piston handle 12 is formed with screw rod perforation 18, screw rod
The inner side of perforation 18 is formed with the screw thread engaged with screw rod 13 (outside is formed with screw thread).Perforated via screw rod at second end of screw rod 13
18 extend to the outside of piston handle 12 so that 11 pieces of rotation gear is located at the outside of piston handle 12.
Piston head 15 is contained in body 20, and body 20 has delivery outlet 22 in its first end, and physiological saline is contained in defeated
In the second space 21 limited between outlet 22 and piston head 16.Second end of body 20 is formed with rod aperture, and piston rod is certainly
Rod aperture is extended through outside body 20.
Cue mark is formed further with body 20, when at least piston head advances to the position, it should carry out physiology salt
The mixing of water and liquaemin is manipulated；In other words, the physiological saline now retained in second space and the liver retained in the first space
The mixed proportion of plain sodium conforms exactly to requirement, will not overrich or excessively light.
The minimum diameter of first plug 14 is more than the maximum gauge of the delivery outlet 22 of body 20 so that the first plug 14 will not
Block delivery outlet 22.
Before being not used, also this has block 30 on delivery outlet.
The diameter of rotary block 11 is greater than the diameter of screw rod perforation 18, plays spacing effect.
When being rinsed operation, take out first it is as shown in Figure 1 it is pre- rush formula tube sealing syringe, remove block 30, pass through
Piston handle 12 promotes piston so that the physiological saline in second space rushes in CVC, transfusion via delivery outlet 22
In port etc., the decoction wherein remained is rinsed.After rinsing to predetermined graduated (as shown in Figure 2), pass through rotary block 11
Swivel bolt 13, makes it close to the first plug 17, pushes the first plug from there through the liquaemin in the first space, fall
Enter in second space 21 (as shown in Figure 3), continue swivel bolt 13 until the second plug 14 reaches the first side of piston head 16 (such as
Shown in Fig. 4), complete liquaemin and mixing of the physiological saline in second space 21.Then, piston handle 12 is continued to press on, will
The tube-sealing solution mixed is pushed in CVC, transfusion port etc. via delivery outlet 22 and carries out tube sealing (as shown in Figure 5).
