Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the decomposing schematic representation of embodiment 1 of the present utility model.
Fig. 3 is the decomposing schematic representation of embodiment 2 of the present utility model.
1 helmet, 2 female Luer, 3 coneheads, 4 overcoats, 5 plugs, 6 push rods, 7 press hand, 8 sterilization blocks, 9 sponges, 10 cutting ferrules, 11 breach, 12 sheaths, 13 Sealing pieces.
The specific embodiment
The utility model syringe construction helmet 1, overcoat 4, plug 5, push rod 6 are similar to ordinary syringe overall structure, push rod 6 is contained in overcoat 4, push rod 6 front ends are connected with plug 5, plug 5 and overcoat 4 interference fit, push rod 6 push-and-pull plugs 5 seesaw in overcoat 4, and overcoat 4 front ends are provided with conehead 3.Wherein overcoat 4 can be vacant i.e. pre-filling injection liquid not, also can be filled with in advance flushing, the tube-sealing solutions such as physiological saline, liquaemin.
Conehead 3 is externally connected with helmet 1; as a kind of preferred structure; overcoat 4 walls are provided with annular retaining ring around conehead 3; on this annular retaining ring inwall, be provided with female Luer 2; the internal thread that helmet 1 outside of syringe is provided with external screw thread and female Luer 2 cooperatively interacts; can the contact-making surface between conehead 2 outer walls and helmet 1 inwall further be sealed, play the effect of preliminary filling liquid in protection overcoat 4.If syringe is preliminary filling liquid not, this female Luer can coordinate with the puncture needle with female Luer, for drawing parenteral solution to syringe.
On the push rod 6 of the utility model syringe, be provided with the device of encapsulation sterilization block, in described sterilization block 8, be provided with the sponge 9 that is soaked with thimerosal.The present embodiment has provided two kinds of preferred embodiments of the present utility model, but the utility model is not limited to this.
Embodiment 1
As shown in Figure 2, the device of encapsulation sterilization block is comprised of cutting ferrule 10, sheath 12 and Sealing piece 13, cutting ferrule 10 be fixed on push rod 6 by hand 7, sheath 12 is sleeved in cutting ferrule 10, sterilization block 8 is placed in sheath 12, Sealing piece 13 is by sheath 12 openings sealings.As a kind of optimal way, sterilization block 8 is soft material, and cutting ferrule 10 sidewalls have two breach 11 at place, nearly bottom, is convenient to the sheath in cutting ferrule 10 12 to release.The outer surface of the inner surface of the inner surface of cutting ferrule 10 and sheath 12 outer surfaces and sheath 12 and sterilization block 8 all arranges the nicking that cooperatively interacts.The nicking of the outer surface of sheath 12 has enough frictional force while guaranteeing to screw sheath 12, the nicking that the outer surface of the inner surface of sheath 12 and sterilization block 8 cooperatively interacts, can make nurse after screwing sheath 12, sterilization block 8 does not produce slip with sheath 12, thereby closely screws in fluid infusion port place.
During use, when nurse uses syringe, complete after flushing, tube sealing operation, syringe is taken off from fluid infusion port, from cutting ferrule 10 use fingers, the sheath 12 that sterilization block is housed is taken out, Sealing piece 13 is torn.The block sheath 12 of sterilizing is aimed at fluid infusion port (as positive pressure connector etc.) and is screwed in the direction of the clock.Sterilization block 8 is fixed on to fluid infusion port place, detaches backward sheath 12, sterilization block 8 is connected to fluid infusion port place together with 9, the sponge that is soaked with thimerosal inside.The sponge 9 and fluid infusion port close contact that are soaked with thimerosal, play the disinfection protection effect to fluid infusion port.When nurse carries out flushing next time, tube sealing operation, the block 8 of sterilizing is separated from fluid infusion port, can rush tube sealing operation.After complete operation, continue sterilization block 8 again to aim at fluid infusion port operation, can complete the protection work to port.
Embodiment 2
As shown in Figure 3, the device of encapsulation sterilization block is comprised of cutting ferrule 10 and Sealing piece 13, cutting ferrule 10 be fixed on push rod 6 by hand 7, sterilization block 8 be rigid plastics, is provided with the sponge 9 that is soaked with thimerosal in it, Sealing piece 13 involutions are blocked a shot on 8 in sterilization.Sterilization block 8 is contained in cutting ferrule 10, and the block 8 of sterilizing while using by the bottom notch 11 of cutting ferrule 10 is released from cutting ferrule 10.The nicking that the outer surface of sterilization block 8 and the inner surface setting of cutting ferrule 10 cooperatively interact.
During use, nurse uses syringe to complete after flushing, tube sealing operation, and syringe is taken off from fluid infusion port, from cutting ferrule 10 use fingers, sterilization block 8 will be housed and take out, and Sealing piece 13 is torn.The block 8 of sterilizing is aimed at fluid infusion port (as positive pressure connector etc.) and is screwed in the direction of the clock.Sterilization block 8 is fixed on to fluid infusion port place, is soaked with the sponge 9 and fluid infusion port close contact of thimerosal, play the disinfection protection effect to fluid infusion port.When nurse carries out flushing next time, tube sealing operation, the block 8 of sterilizing is separated from fluid infusion port, can rush tube sealing operation.After complete operation, continue sterilization block 8 again to aim at fluid infusion port operation, can complete the protection work to port.
From the foregoing, the use of sterilization block makes that fluid infusion port sterilizing operation is simple, standardization.
