The specific embodiment
With the following Examples this utility model is further described.
Embodiment 1.
A kind of syringe of reusable assist device as shown in Figure 1, is provided with device for storing liquid 100, assist device 200, also is provided with injection needle 300, needle guard 400.Device for storing liquid 100 is used for the liquid of ccontaining suction, and assist device 200 aspirates or injects liquid under external force.
Device for storing liquid 100 is provided with jointing 110 and elasticity medicine bag 120, and elasticity medicine bag 120 is assemblied in the inner chamber of jointing 110, and elasticity medicine bag 120 is connected with jointing 110 bore seal.Concrete, elasticity medicine bag 120 can be tightly connected by ultrasonic bonding or by alternate manner with the inner chamber of jointing 110.
When liquid process jointing 110 sucks, because elasticity medicine bag 120 is tightly connected with jointing 110, liquid will be stored in the space of elasticity medicine bag 120 and jointing 110 formations, and can not contact other parts of syringe.Along with the increase of the inhalant liquid scale of construction, liquid can strut elasticity medicine bag 120.
Need to prove that jointing 110 is not limited to being threaded in the present embodiment with the assembling mode of overcoat 210, also can according to circumstances be set to buckle connection or alternate manner and connect.
The syringe of this reusable assist device, its operation principle is such: when external force pull core bar 220, core bar 220 courts move away from the direction of the assembling end 211 of overcoat 210, be negative pressure state in the overcoat 210 this moment, outside liquid will suck in the elasticity medicine bag 120 by jointing 110, along with the elasticity medicine bag 120 that increases that sucks liquid will be strutted.Because elasticity medicine bag 120 is tightly connected with jointing 110, medicinal liquid can only be present in the space of elasticity medicine bag 120 and jointing 110 formations, and can not enter overcoat 210, so medicinal liquid can not pollute overcoat 210 and core bar 220.When external force promotion core bar 220 is injected, pressure in the overcoat 210 increases, promote elasticity medicine bag 120 extruding liquid liquid is injected away by jointing 110, this process herb liquid only exists only in device for storing liquid 100, so medicinal liquid can not pollute overcoat 210 and core bar 220.Whole assist device 200 is in the process of carrying out imbibition and injecting fluid, medicinal liquid only exists only in the device for storing liquid 100, and can not contact assist device 200, so after injection finishes, as long as change device for storing liquid 100, injection needle 300 parts, assist device 200 originally still can be used safely.
Because assist device 200 can be repeatedly used, so can reduce patient's economic pressures and can save raw material, compliance with environmental protection requirements greatly.
In addition, the syringe construction of the reusable assist device of present embodiment is simple, and is with low cost, uses safety.
Embodiment 2.
A kind of syringe of reusable assist device, other structure is identical with embodiment 1, difference is: cyst wall 121 and blister cavities 122 are set to integrated formed structure, have easy to process, with low cost, good sealing effect specific.
Embodiment 3.
A kind of syringe of reusable assist device, other structure is identical with embodiment 1 or 2, difference is, also has following technical characterictic: as Fig. 2, Fig. 3, shown in Figure 4, its assist device 200 also is provided with one-way locking mechanism, and one-way locking mechanism is provided with mount pad 231, injection buckle 232 and elastic component 233.
In addition, this assist device 200 also is provided with core bar locator card 240, and core bar locator card 240 is sheathed on the opening end 212 that core bar 220 and core bar locator card 240 are assemblied in overcoat 210.Core bar locator card 240 is provided with draw-in groove 241, and strip shape body and draw-in groove 241 are complementary.
The button bit 222 of core bar 220 is connected with buckle end 2321 buckles, and the two ends of elastic component 233 are connected to the outside wall surface of tail end 2322 and overcoat 210.When carrying out the liquid suction, external force is twitched core bar 220 and is moved towards opening end 212 directions away from overcoat 210, this moment is because the effect of external force, the buckle end 2321 that is stuck in button bit 222 will be subjected to the thrust of core bar 220, make the tail end 2322 of elastic component 233 compressions, injection buckle 232 do small size displacement towards close mount pad 231 directions, core bar 220 can move, movement along with core bar 220, assist device 200 inside are negative pressure state, and liquid enters device for storing liquid 100 inside by injection needle 300.After pumping liquid finishes, because buckle end 2321 buckles are connected in button bit 222, the positioning action of core bar locator card 240 in addition, core bar 200 will be in original position and can not move.If when external force promotion core bar 210 holds 211 directions to move towards the assembling of close overcoat 210, owing to the effect of tail end 2322, elastic component 233, promote the button bit 222 and buckle end 2321 snappings of core bar 220 this moment, core bar 220 can not move in the overcoat 210.Injection if desired only needs rotation core bar 220, makes the button bit 222 of core bar 220 stagger with buckle end 2321 and can carry out liquid infusion.
By this one-way locking mechanism, can suck or injection by liquid with precise control, more safe and reliable.
The syringe of this reusable assist device, its whole assist device 200 is in the process of carrying out imbibition and injecting fluid, and medicinal liquid only exists only in the device for storing liquid 100, and can not contact assist device 200.So after injection finishes, reserve part 60 after the syringe that keeps this reusable assist device uses, after using, the syringe that abandons this reusable assist device abandons part 70, as shown in Figure 5, namely as long as with original device for storing liquid 100, injection needle 300 parts, needle guard 400 parts abandon, and keep original assist device 200 parts, again with original device for storing liquid 100, injection needle 300 parts, needle guard 400 is assemblied in original assist device 200 parts and can reuses, and newly assembled syringe can be because of last time injection and caused cross-contamination.
Because assist device 200 can be repeatedly used, so can reduce patient's economic pressures and can save raw material, compliance with environmental protection requirements greatly.
In addition, the syringe construction of the reusable assist device of present embodiment is simple, and is with low cost, uses safety.
Embodiment 4.
A kind of device for storing liquid is for the syringe of above-described embodiment 1 to 3 any a reusable assist device.As shown in Figures 1 to 4, this device for storing liquid 100 is provided with jointing 110 and elasticity medicine bag 120, and elasticity medicine bag 120 is assemblied in the inner chamber of jointing 110, and elasticity medicine bag 120 is connected with jointing 110 bore seal.
This device for storing liquid 100 cooperates assist device 200, can realize that syringe is after injection, only need to change device for storing liquid 100, injection needle 300 and reuse assist device 200 and can form new syringe and use, patient's use cost not only can be saved and raw material, compliance with environmental protection requirements can be saved greatly.
Embodiment 5.
A kind of device for storing liquid, other structure is identical with embodiment 1, difference is: cyst wall 121 and described blister cavities 122 are set to integrated formed structure, have easy to process, with low cost, good sealing effect specific.
Should be noted that at last; above embodiment only is used for the explanation the technical solution of the utility model but not to the restriction of this utility model protection domain; although with reference to preferred embodiment this utility model has been done detailed description; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
