Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 .1 ~ Fig. 1 .3, the pre-filled washing pipe tube clipper of monotubular in embodiment 1 is mainly by cylindrical shell, core plug 4 and core bar 6 form, described core plug 4 is arranged on core bar 6 front ends, core plug 4 and core bar 6 are placed in cylindrical shell jointly, the length direction of core bar 6 and the length direction of cylindrical shell are in the same way, the front end face of core plug 4 is parallel with the cylinder bottom surface of cylindrical shell, described cylindrical shell is interior for storing washing pipe liquid, on described core plug 4 front end faces, be provided with the device for storing liquid 3 for storing tube-sealing solution, core bar 6 and core plug 4 promote device for storing liquid 3 while pushing ahead and advance, the cylinder that device for storing liquid 3 contacts cylindrical shell discharges tube-sealing solution behind bottom surface.
As shown in Fig. 1 .1 ~ 1.5, the device for storing liquid 3 in embodiment 1 is elasticity medicine bag, and the cylinder bottom surface of described cylindrical shell is provided with pricker 9, and when elasticity medicine bag advances to the cylinder bottom surface that touches cylindrical shell, elasticity medicine bag is punctured by pricker 9, thereby discharges tube-sealing solution.
As shown in Fig. 1 .1 ~ 1.5, described cylindrical shell is mainly made up of stack shell 2 and tailstock 5, and the inwall of described stack shell 2 rear ends is provided with female thread; Described tailstock 5 is made up of straight tube 5a and ring flat-plate 5b, and described straight tube 5a is provided with external screw thread, and the straight tube 5a of tailstock 5 is threaded with stack shell 2 rear ends, and the ring flat-plate 5b of tailstock 5 is as the grip part of clinical manipulation; An edges of boards for described core bar 6 rear ends are provided with elastic clipping strip 7 and breach 8, the support plate of described elastic clipping strip 7 front ends and core bar 6 is connected as a single entity, elastic clipping strip sticks up outside 7 rear ends, described breach 8 is corresponding with elastic clipping strip 7 positions, when elastic clipping strip 7 pressurized, embed in breach 8, after core bar 6 pushes in cylindrical shell completely, elastic clipping strip 7 is upspring and is stuck in the front end of tailstock 5 straight tube 5a.
In the present invention, described washing pipe liquid is class physiological liquid, comprises normal saline, balance liquid; Described tube-sealing solution is the heparin liquid of tube sealing concentration, and the heparin solute in heparin liquid comprises heparin sodium, clarin, also can be the mixed liquor containing heparin solution and other medicinal liquids.
The manufactured materials of described cylindrical shell, core bar 6 comprises medical plastic etc., and the manufactured materials of described core plug 4 comprises medical grade rubber, silica gel etc.
In addition, for easy to use, on described cylindrical shell, be provided with label, on described label for marking the information of washing pipe liquid, tube-sealing solution.
the concrete applicable cases of this washing pipe tube clipper is as follows:
1, assemble the pre-filled washing pipe tube clipper of monotubular and pack medicinal liquid into:
Before assembling, at the interior tube-sealing solution that poured into of device for storing liquid 3, core plug 4 and device for storing liquid 3 are filled in stack shell 2 from stack shell 2 open rearward end in the lump, then tailstock 5 is threaded on stack shell 2.Tailstock 5 straight tube 5a front ends will be moved to after core plug 4 and device for storing liquid 3.Place stack shell 2 vertically, make the drain pipe 1 of stack shell 2 front ends vertically upward, from drain pipe 1 to the interior washing pipe liquid that poured into of stack shell 2, then cover sealing cap.Core plug 4 is interior when mobile at stack shell 2, and the surface of the neighboring of core plug 4 and stack shell 2 inwalls is close to, air tight or leakage.By core bar 6 with the device for storing liquid that assembled is placed side by side and packing (shown in Fig. 1 .2).
2, washing pipe:
Before use, take out core bar 6, insert and be connected to core plug 4 from tailstock 5 centers, Product Assembly completes (shown in Fig. 1 .3).After the drain pipe of barrel front end 1 is closely connected with blood vessel indwelling path, promote core bar 6, it is advanced in cylindrical shell, adopting pulsed to advance (pushes away, stop), make washing pipe liquid form little whirlpool in blood vessel indwelling path, clean by being attached to medicine liquid washing in blood vessel indwelling path and blood vessel wall.Before punching is closed and finished, the elastic clipping strip 7 on core bar 6 is subject to the pressure of cylinder inboard wall and embeds in the breach corresponding with it 8 in progradation, thereby can not affect the propelling of core bar 6.Now, in the pre-filled washing pipe tube clipper of monotubular the position relationship of each parts as shown in Fig. 1 .4.
3, tube sealing:
After washing pipe liquid is all totally lost, the elasticity medicine bag that stores tube-sealing solution touches the pricker 9 on cylindrical shell cylinder bottom surface, elasticity medicine bag is punctured by pricker 9, thereby release tube-sealing solution, continues to promote core bar 6, makes core bar 6 and core plug 4 in cylindrical shell, continue to push ahead, adopting pulsed to advance (pushes away, stop), make tube-sealing solution form little whirlpool in blood vessel indwelling path, clean by being attached to medicine liquid washing in blood vessel indwelling path and blood vessel wall.In the time that core bar 6 is advanced to the end, core plug 4 is closely pressed the cylinder end of touching cylindrical shell, and the elastic clipping strip 7 on core bar 6 is upspring and is stuck in the front end of tailstock 5 straight tube 5a, make core bar 6 fixing, can not retreat, thereby blood and washing pipe tube-sealing solution can not be refluxed, ensure the safety of operation.So far, washing pipe tube sealing has operated, and takes off this device sealing blood vessels indwelling path.Now, in the pre-filled washing pipe tube clipper of monotubular the position relationship of each parts as shown in Fig. 1 .5.
