Further, the junction point of described diaphragm seal and piston rod is not less than the length of syringe to the distance of piston.
Further, described piston rod arranges gripping groove near piston handle place.
Further, inside described syringe, projection is set near syringe handle place.Can avoid so excessively pulling piston rod, piston rod is come off in syringe.
Further, the syringe of described syringe arranges volume markings.
This utility model also provides a kind of central vein catheter flusher, solves existing backwashing manner complex operation, is repeatedly exposed to outer operation, there is pollution risk, cause the problem of potential safety hazard.
This utility model solves the technical scheme that its technical problem adopts: central vein catheter flusher, comprise the arbitrary syringe of such scheme and threeway, the nipple connecting tee of described syringe, Vein Tube joint centered by one end of described threeway, the other end of threeway connects perforator.
Use this utility model central vein catheter flusher, perforator is inserted in normal saline bag, adjustment three-way valve, by operating syringe, the gas in pipeline is drained, be connected with the central vein catheter of patient by central vein catheter joint, adjustment three-way valve, by normal saline first suction syringe, adjust three-way valve again, and inject normal saline central vein catheter is rinsed.Repeatedly can inject flushing as required.
Further, the pipeline between described threeway and central vein catheter joint arranges arm, and described arm is sealed by calparine cap.When needs inject anticoagulant in central vein catheter, after adjustable three-way valve, then inject from calparine cap.
Further, the maximum volume of described syringe is 5 ~ 20ml.
Further: be an overall structure between described nipple and threeway.
Further: the conduit between described threeway and perforator arranges flow-stopping clip, on described perforator, pin cap is protected in setting.
The beneficial effects of the utility model are: the first, this utility model syringe can avoid hands to contact with the direct of piston rod, strengthen the safety used;
The second, this utility model central vein catheter flusher, can rinse central vein catheter easily, and without the need to exposure operation, can the flushing nursery work of center of reduction Vein Tube, improves safety simultaneously.

Fig. 1 is the structural representation of this utility model syringe;
Fig. 2 is the structural representation of this utility model central vein catheter flusher first embodiment;
Fig. 3 is the structural representation of this utility model central vein catheter flusher second embodiment.
Parts, position and numbering in figure: syringe 11, piston 12, nipple 13, piston rod 14, syringe handle 15, piston handle 16, protruding 17, gripping groove 18, diaphragm seal 20, threeway 30, central vein catheter joint 31, perforator 32, protect pin cap 33, flow-stopping clip 34, calparine cap 35.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this utility model " syringe " comprises syringe 11 and piston rod 14, and described piston rod 14 one end is piston 12, and piston rod 14 other end is piston handle 16, piston 12, piston rod 14 and piston handle 16 preferably can be an entirety, also can be formed by connecting respectively.Piston rod 14 arranges gripping groove 18 near piston handle 16 place, injects so that be hold by one hand.
Described syringe 11 one end is nipple 13, syringe 11 other end is syringe handle 15, arranges a circle projection 17 inside syringe 11 near syringe handle 15 place, and protruding 17 can play restriction to the stroke of piston 12, avoid excessively pulling piston rod 14, make the problem that piston rod 14 comes off in syringe 11.The thickness of protruding 17 should not be too large, such as, be 1 ~ 2mm, avoids the protruding 17 blocked up pistons 12 that cause can not put into syringe 11.Outside syringe 11, also volume markings is set.
Arrange diaphragm seal 20 between syringe handle 15 and piston rod 14, diaphragm seal 20 is accordion, or selects elastica, so that automatic rebounding shrinks.Length after diaphragm seal 20 stretches is not less than the length of syringe 11, and the length after preferred diaphragm seal 20 stretches completely equals the length of syringe 11.Diaphragm seal 20 one end is adhered on syringe handle 15, and the other end is adhered on piston rod 14, and forms the sealing of ring-type, and the junction point of diaphragm seal 20 and piston rod 14 is not less than the length of syringe 11 to the distance of piston 12.Optimal way is that diaphragm seal 20 is adhered to gripping groove 18 away from piston handle 16 side, and the junction point of diaphragm seal 20 and piston rod 14 equals the length of syringe 11 to the distance of piston 12.
In addition, this utility model also discloses a kind of central vein catheter flusher, is described central vein lrrigation device below in conjunction with two embodiments.
First embodiment
As shown in Figure 2, central vein catheter flusher, comprises said syringe and threeway 30, the nipple 13 of described syringe is connected with threeway 30, Vein Tube joint 31 centered by one end of threeway 30, the other end of threeway 30 connects perforator 32, perforator 32 is arranged and protects pin cap 33.Can be formed by connecting between threeway 30 and nipple 13, can being also an overall structure, in order to ensure the intensity between threeway 30 and nipple 13, preferably adopting overall structure.
Use central vein catheter flusher, first insert in normal saline bag by perforator 32, the valve of adjustment threeway 30, is drained the gas in pipeline by operating syringe; Then central vein catheter joint 31 is connected with the central vein catheter of patient, the valve of adjustment threeway 30, by first for normal saline suction syringe, then adjusts the valve of threeway 30, and inject normal saline central vein catheter is rinsed.The volume capacity of syringe is advisable with 5 ~ 20ml, can once or repeatedly complete the flushing of central vein catheter.
Conduit between threeway 30 and perforator 32 is arranged flow-stopping clip 34, as subsequent use, prevent normal saline to be back to bag of saline.
