Description
Technical field
This utility model relates to medical instruments field, particularly a kind of noncontact precharging type syringe.
Background technology
At present, on market, precharging type syringe all adopts the version of original syringe, it is definitely piston smooth and easy movement in propelling movement seat after preliminary filling liquid, rubber piston need infiltrate silicone oil, when piston promotion liquid medicine is injected, piston can contact with liquid medicine, and the silicone oil on piston can be contacted with liquid medicine, constrains the growth momentum that precharging type syringe substitutes most of water preparation Medical Packing Materials because of silicone oil and the issuable harmful substance of medicine.
Utility model content
Utility model object: in order to solve problems of the prior art, this utility model provides a kind of noncontact precharging type syringe, silicone oil can either be avoided to pollute liquid medicine and can complete injection smoothly again.
Technical scheme: this utility model provides a kind of noncontact precharging type syringe, comprises liquid medicine bag assembly, syringe and push rod, described liquid medicine bag assembly is made up of liquid medicine bag and joint; One end that described joint is fixedly connected with liquid medicine bag is the cylindrical section with through hole, and the other end is interface, and joint is tightly connected through syringe front opening and syringe, and liquid medicine bag and cylindrical section are positioned at syringe, and interface is positioned at outside syringe; Described push rod is cut somebody's hair by push rod and the plunger type that can fit tightly with syringe and is formed, described plunger type cut somebody's hair be positioned at the inner liquid medicine bag of syringe bag at the bottom of rear, and plunger type is cut somebody's hair and not to be contacted with liquid medicine bag.
Preferably, the cylindrical section of described joint is provided with kidney-shaped boss, described syringe front opening place is provided with and can coordinates with described kidney-shaped boss the mounting hole be fixedly connected with, and described kidney-shaped boss is fixedly connected with mounting hole by screwing cap, screws cap and is arranged on interface.
Preferably, the rear end of described syringe is provided with symmetrical projecting hook hands.
Preferably, this syringe also comprises dismountable capping, and this capping is provided with revolves tooth, this revolve tooth can with screw cap with the use of, enter to screw cap by tooth spiral will be revolved capping covered on interface.
Preferably, described joint is female Luer, and described interface is female Luer.
Preferably, described syringe and liquid medicine bag are by weld or bonding mode is fixedly connected with.
Operation principle and beneficial effect: because the joint of liquid medicine bag and needle tubing are tightly connected in this utility model, and the plunger type of push rod is cut somebody's hair and can be fitted tightly with syringe inwall, syringe inside is equivalent to a confined space, so in the process of push rod to the inner movement of syringe, air in syringe can be compressed, plunger type cut somebody's hair and at the bottom of liquid medicine bag bag between air shrink owing to being promoted liquid medicine bag by compressing, thus the liquid medicine in liquid medicine bag successfully to be injected away by joint.Plunger type due to this syringe is cut somebody's hair all the time can not with liquid medicine bag contact, liquid medicine bag can not be caused to break, even if so plunger type scribbles silicone oil on cutting somebody's hair or other lubricants also can not cause the liquid medicine in liquid medicine bag and silicone oil or other lubricant generation chemical reactions to cause the generation of harmful substance, this product has should have prospect widely.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1, noncontact precharging type syringe in present embodiment is by liquid medicine bag assembly, syringe 1 and push rod composition, liquid medicine bag assembly is made up of liquid medicine bag 2 and joint, liquid medicine bag 2 and joint integrative-structure in present embodiment are (structural representation of liquid medicine bag assembly as shown in Figure 2, Fig. 3 is the left view of Fig. 2), joint (in the following description for female Luer) one end is the cylindrical section 3 with through hole, the other end is interface 4 (in the following description for female Luer), cylindrical section 3 is connected with the forward end seal of liquid medicine bag 2, it is inner that liquid medicine bag 2 is placed in syringe 1, joint is tightly connected through the opening of syringe 1 front end and syringe 1, it is inner that cylindrical section 3 stays syringe 1, female Luer 4 is positioned at syringe 1 outside for connecting needle, in the present embodiment, cylindrical section 3 is provided with kidney-shaped boss 7, syringe 1 front opening place is provided with and can coordinates the mounting hole 8 be fixedly connected with this kidney-shaped boss 7, kidney-shaped boss 7 and mounting hole are connected and fixed through the cap 11 that screws be arranged on interface 4 and seal, push for the ease of implementing, syringe 1 rear end can be provided with symmetrical projecting hook hands 9, syringe 1 front opening can make mounting hole, and interface can arrange kidney-shaped platform, is convenient to be fastenedly connected with syringe needle, push rod 5 front end of push rod is provided with the plunger type that can fit tightly with syringe 1 inwall and cuts somebody's hair 6, and this is cut somebody's hair and 6 is positioned at liquid medicine bag 2 rear and does not contact with liquid medicine bag 2, and under the drive of push rod 5, plunger type is cut somebody's hair and 6 can be moved around along syringe 1 inwall.The structural representation of push rod as shown in Figure 4.
Because syringe 1 and female Luer seal, and plunger type cut somebody's hair 6 and syringe 1 inwall also fit tightly, so be equivalent to an airtight space in syringe 1, when manually promoting the push rod 5 of push rod, push rod 5 drives plunger type to cut somebody's hair and 6 to move forward along syringe 1 inside, air in syringe 1 is become large by compression gas-pressure, plunger type cut somebody's hair at the bottom of 6 and liquid medicine bag 2 bags between air pressure can liquid medicine be forced to inject away from female Luer by compacted medicament water bag 2.In whole injection process, plunger type is cut somebody's hair between 6 with liquid medicine bag 2 and is not contacted, and liquid medicine bag 2 can not be broken, even if so plunger type is cut somebody's hair on 6 infiltrated silicone oil or other lubricants, silicone oil and other lubricants also can not pollute liquid medicine.View when this syringe completes injection as shown in Figure 5.
Embodiment 2:
Present embodiment is roughly the same with embodiment 1, the main distinction is, in present embodiment, liquid medicine bag 2 and joint are not integrative-structures, adopt between syringe 1 front end and liquid medicine bag 2 and do not weld or to be cementingly fixed together, as shown in the numbering 12 in Fig. 6, the alternate manner easily can certainly expected by those skilled in the art is connected, and does not repeat herein.
Embodiment 3:
Present embodiment is the further improvement of embodiment 1 or 2, main improvements are, in order to prevent the liquid medicine of syringe when off position in liquid medicine bag from naturally flowing out through female Luer due to action of gravity in present embodiment, increase a dismountable capping 10, as shown in Figure 7, capping has with screw cap 11 with the use of revolve tooth, the tooth spiral that revolves of capping 10 is entered female Luer 4 screws in cap 11 and namely female Luer 4 can be sealed, avoids liquid medicine naturally to flow out.In addition, present embodiment is identical with embodiment 1, does not repeat herein.As the overall structure schematic diagram that Fig. 7 is the syringe in present embodiment.
By reference to the accompanying drawings embodiment of the present utility model is elaborated above, but this utility model is not limited in above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from this utility model aim.
