Specific implementation method
Below, in conjunction with Figure of description, the present invention is further detailed.
First embodiment
As shown in Figure 1, comprise pedestal 2, mixed medicine glass 3, barrier film 8 and mixed medicine passage 7, the above-mentioned medicine mixer body construction be made up of pedestal 2, mixed medicine glass 3, barrier film 8 and mixed medicine passage 7 is formed in integrated mode.
Plug 6 is placed in mixed medicine passage, is positioned on barrier film 8.
Elastic clamp seat 4 is as described in Figure 3 placed in mixed medicine glass, as figure 4 ?the cross needle 5 shown in 8 be placed in elastic clamp seat 4, thus the medicine mixer formed as shown in Figure 9, after elastic clamp seat 4 and cross needle 5 install, there is cover plate 12 at the rim of a cup position of sound production of mixed medicine glass 3, then cover diaphragm seal 13 and mixed medicine glass is sealed.
Be understandable that, infusion channel 11, can be one-body molded together with above-mentioned medicine mixer body construction, also can adopt other infusion connector when soft bag bag.
Mixed medicine passage 7 through pedestal 2 upwards extends straight-through to mix at the bottom of the cup of medicine glass 33 ?2, the effect of barrier film 8 is that isolated medicinal liquid contacts with the direct of plug, accomplish the sealing completely before using, can be arranged in any position of the mixed medicine passage under plug 6 in theory, such as the barrier film 8 shown in Fig. 1,11 is close under plug 6; Or as shown in Fig. 9,12,13, barrier film 8 is positioned at the position under plug.But consider if barrier film 8 position is too low, cause lower pin 5 ?3 of cross needle 5 long, so preferably barrier film 8 to be positioned under plug 6 and to be close to the lower surface of plug 6.
Plug 6 is placed in mixed medicine passage, on barrier film.The effect of plug be ensure lower pin 5 ?3 after puncture plug 6 with barrier film 8, medicinal liquid from barrier film 8 and lower pin 5 ?flow out gap between 3 outer walls after be unlikely to ooze out mixed medicine passage, that is, the external diameter of plug 6 and the internal diameter of mixed medicine passage match, and make plug 6 and mixed medicine passage close contact.
Preferably, at the bottom of plug 6 upper surface and cup 3 ?2 upper surfaces substantially flush with or slightly higher than upper surface, thus, the lower surface of elastic clamp seat 4 as shown in Figure 3, pushes down the upper surface of plug 6.
As a preferred technical scheme, barrier film 8 to be positioned under plug 6 and to be close to the lower surface of plug 6, can better prevent medicinal liquid from after lower needle-penetration barrier film, infiltrating mixed medicine passage.Especially, plug be as described in Figure 2 provided with on the surface by bulge loop or groove 6 ?2,6 ?3 thinner paracentesis areas limited 6 ?1, relative with the bulge loop on plug or groove, the corresponding position of barrier film 8 upper surface is also provided with groove or bulge loop.It is evident that, the bulge loop on plug or groove and the groove on barrier film 8 or bulge loop mutually chimeric, thus reach the object better preventing Drug leakage.
Be provided with plug 6 and the barrier film 8 of mutually chimeric groove or bulge loop, after elastic clamp seat 4 pairs of plugs 6 form a squeezing action, the seepage of medicinal liquid after mixed medicine can being stopped completely.
For elastic clamp seat 4 as shown in Figure 3, comprise a snap ring 4 ?6, be provided with on the downside of described snap ring elastic card claw 4 ?1, described elastic card 4 ?snap ring described in 1 upper end edge to be evenly arranged and fixing, described elastic card claw 4 ?1 lower end be free end, and described elastic card claw from fixing described upper end to described lower end freely in the centroclinal structure of described mixed medicine glass.Described elastic clamp seat have integrated base plate 4 ?5, support column 4 ?4, snap ring 4 ?6 and elastic card claw 4 ?1, described base plate 4 ?5 peripheries be provided with support column 4 ?4 to described snap ring 4 ?6 formed support fixing.
Described base plate 4 ?5 be provided with centre bore 4 ?3, described lower pin 5 ?3 through described centre bore, location is formed to described crosspointer.Around being provided with circle annular projection 4 ?2 around centre bore 4 ?3, after elastic clamp seat 4 is installed in mixed medicine glass, annular projection 4 ?2 on elastic clamp seat 4 can form a squeezing action to plug.
Described wall of cup 3 ?1 inwall on be provided with restriction protrusion (not shown), described elastic clamp seat 4 is installed in described mixed medicine glass and is limited by described restriction protrusion.
As figure 4 ?crosspointer 5 as described in 8, its needle plate 5 ?1 be installed on described elastic card claw in described mixed medicine glass 4 ?under 1, base plate 4 ?on 5.Crosspointer 5 comprise integrated hollow upper pin 5 ?2 and lower pin 5 ?3 and needle plate 5 that upper pin and lower pin are combined as a whole ?1, upper pin 5 ?2, lower pin 5 ?3 heads be provided with needle point 5 ?5.
For crosspointer 5, the outlet of the hollow channel of upper pin 5 ?4, can be opened in described upper pin 5 ?2 syringe needle sidewall on; Same, the outlet of the hollow channel of described lower pin, be opened in described lower pin 5 ?3 syringe needle sidewall on (not shown).Setting like this is that the edge of outlet forms directly cutting to stopper and produces a large amount of chips in order to avoid upper pin, lower pin are when puncturing plug, bottle stopper.By being arranged on the sidewall of syringe needle by outlet, needle point directly thrusts in plug, can not form direct dissection, reduces the generation of chip.
Or, as figure 7 ?shown in 8, upper pin is coated with one deck elastic contraction film, and elastic contraction film is compressed after piercing, is deposited in around puncturing hole, thus can effectively prevent medicinal liquid along puncturing hole gap leakage out.It is evident that, lower pin equally can coated one deck elastic contraction film, to solve seepage to appear in medicinal liquid problem along the gap of puncturing hole.
For the combination of crosspointer 5, elastic clamp seat 4 and mixed medicine glass 3, pedestal 2, as described in Figure 9, mixed medicine glass and pedestal one-body molded, and elastic clamp seat 4 is placed in 3 of mixed medicine glass, and crosspointer 5 is fastened in elastic clamp seat 4.
Specifically, elastic clamp seat 4 is placed in after in mixed medicine glass 3, be arranged at wall of cup 3 ?1 inwall on restriction protrusion (not shown) limit, thus make elastic clamp seat 4 can not skid off mixed medicine glass after placing.In addition, the confined position of elastic clamp seat 4, make the bottom of elastic clamp seat 4 to contact at the bottom of the cup of described mixed medicine glass 33 ?2.In the plan of establishment of preferred plug 6, annular projection bottom elastic clamp seat 44 ?2 can form extruding to plug 6.
Be installed on the crosspointer 5 among elastic clamp seat 4, needle plate 5 ?1 of crosspointer 5 is between elastic card claw 4 ?1 and base plate 4 ?5, and after being provided with, lower pin 5 ?3 does not pierce through plug 6.
Certainly, be also understandable that, before the use, lower pin 5 ?3 parts thrust in plug 6, or as shown in Figure 9 plug 6 to be punctured completely, or more preferably an aperture is preset at plug 6 center, form annular plug, lower pin 5 ?3 by aperture puncture plug 6, are all feasible schemes.When being designed to annular plug, plug central small hole diameter than lower pin 5 ?3 little, make lower pin 5 ?3 insert apertures in plug 6 and through after plug 6, lower pin 5 ?3 pairs of plugs 6 can not form dissection, thus can effectively avoid lower pin 5 ?3 form the pollution that micro-bits cause medicinal liquid when puncturing plug 6.And, due to hole diameter than lower pin 5 ?3 external diameter little, plug 6 still can be close to lower pin 5 ?3 thus avoid leakage.
As for the state used, as shown in Figure 14,15, cillin bottle 9 inserts in mixed medicine glass 3, the bottle cap of cillin bottle 9 is pressed in elastic clamp seat 4, make elastic card claw 4 ?1 free end be positioned at the bottleneck of cillin bottle 9 and be stuck in described bottleneck, thus can not to exit from mixed medicine glass 3 cillin bottle 9 is stuck.
Meanwhile, the bottle cap of cillin bottle 9 by upper pin 5 ?2 to pierce through, bottle cap push downwards needle plate 5 ?1, thus promote lower pin 5 ?3 pierce through plug 6, then pierce through barrier film 8, mixed medicine passage 7 is communicated with cillin bottle by crosspointer 5.
It is evident that, the snap ring of elastic clamp seat 44 ?6 internal diameters and cillin bottle external diameter basically identical, or slightly larger than described cillin bottle external diameter.And in order to better fixedly limit cillin bottle 9, cillin bottle 9 is not slided, the bottle cap thickness of cillin bottle 9 should and the free end of elastic card claw 4 ?1 basically identical to the distance between base plate 4 ?5, make cillin bottle 9 just by bottle cap be stuck in elastic card claw 4 ?1 free end and base plate 4 ?between 5, and can not to move up and down.
Certainly, be understandable that, for the consideration of processing tolerance etc., the distance between the free end of elastic card claw 4 ?1 to base plate 4 ?5 slightly larger than bottle cap thickness, also can not appreciable impact cillin bottle docking and fix.
By above-mentioned setting, can to make up a prescription safely, easily and efficiently, dosing, completely solve the secondary pollution problem in link of making up a prescription.Cillin bottle 9 simultaneously also can ensure that transfusion can be reviewed, because after from the elastic clamp seat 4 that cillin bottle 9 docking is fixed to mixed medicine glass 3, just can not nondestructively take out.That is, from making up a prescription, complete to transfusion, until reclaim link, can trace back to added, which kind of medicine what inject is.
And a class is needed to the medicine of special preservation, for example need namely to join i.e. note type, may also there are some inconveniences in above-mentioned medicine mixer because the medicine of cillin bottle fill must be taken to ward, then cillin bottle is docked with medicine mixer, then making up a prescription in ward uses at once.
Namely joining demand namely to meet medical personnel more easily, on the basis of said structure, having set up foldable handle 10, as shown in figure 15.
Foldable handle 10 is set in mixed medicine passage lower end, as shown in figure 15, cillin bottle 9 and the elastic clamp seat 4 in mixed medicine glass 3 is completed after docking and puncturing, bring to pharmacy, before transfusion, break disconnected foldable handle 10, get through mixed medicine passage, dispensing site can be completed, onsite application.
As shown in Figure 1, medicine mixer be arranged side by side together with the infusion channel 11 in pedestal 2, form hard double nip.
Medicine mixer is connected together by the mode of welding with transfusion flexible bag 1, forms the transfusion flexible bag 1 of band medicine mixer, as shown in figure 16.Described medicine mixer connects 1 by described pedestal 2 with transfusion flexible bag and is combined.
Be understandable that, infusion channel 11 can with medicine mixer setting side by side on the base 2, as shown in Figure 1.Infusion channel also can by another one pedestal independent be welded on transfusion flexible bag 1, be arranged at transfusion flexible bag 1 and medicine mixer homonymy or relative opposite side, or other positions of transfusion flexible bag 1 for a person skilled in the art, are all apparent settings.
About shape and the structure of pedestal, after medicine mixer, infusion channel or band medicine mixer and the hard double nip of infusion channel are welded on soft bag, in storage, transport and use procedure, the damage that pedestal welding position causes transfusion flexible bag, foundation design is dumb-bell shape or ship shape, as shown in the pedestal 2 in Fig. 1, and the lower end of mixed medicine passage 7, infusion channel 11 is concordant with the lower end of pedestal 2.Uniform welding lines on the surrounding sidewall of pedestal 2, can well ensure to be in the welding process of transfusion flexible bag like this, even pedestal 2 also well can fuse welding with soft bag 2 at a lower temperature.And, the pedestal of ship shape or dumb-bell shape, streamlined good, improve the mechanical property of welding not to the utmost, and there is no sharp angle, the combination of hard double nip and transfusion flexible bag 2 can be made more level and smooth, not fragile soft bag.
Finally, in order to ensure transfusion flexible bag safety asepsis in use, need to seal mixed medicine glass.Sealed mixed medicine cup generally adopts easily tore film, than even more preferably pp easily tore film, preferably with the pp easily tore film of certain air permeability.Easily tore film is directly pressed together on mixed medicine glass rim of a cup place, during use, directly tears easily tore film.
Because after transfusion flexible bag 1 fill, seal, then carry out high temperature sterilize.If do not sealed mixed medicine glass, the transfusion flexible bag with medicine mixer after sterilizing, due in mixed medicine glass with puncture cross needle 5 be still exposed in external environment condition, transport use time must evitable meeting contaminated, still can not ensure its aseptic.

Wall of cup is arranged reinforcement 3 ?3 substantially can solve mixed medicine glass in sterilization process and be not crushed out of shape, but the diaphragm seal that also there is sealed mixed medicine cup when sterilizing by the problem of compression.
In order to address this problem, be also provided with a cover plate 12 as shown in figure 18 at mixed medicine glass rim of a cup place, diaphragm seal 13 covers cover plate 12, makes cover plate form effective support to diaphragm seal, prevents diaphragm seal when sterilizing by compression.Step-like interior edge is provided with along described wall of cup at rim of a cup place, cover plate is shelved on described step-like interior along upper, make the upper surface of the cover plate being arranged on rim of a cup place concordant with rim of a cup or a little less than described rim of a cup, can not impact the sealing technology of diaphragm seal hot pressing at described wall of cup upper end face.
For the shape of cover plate 12, can be rounded, consistent with mixed medicine glass rim of a cup, but preferred cover plate shape is cross section is polygon, such as pentagon, hexagon, octagon, 12 distortion.
For the setting of cover plate 12, preferred cover plate and cross needle are coaxially arranged, the needle point of upper pin 5 ?5 just to cover plate central.
More have preferably, cover plate central be provided with a through hole 12 ?1, through hole internal diameter be less than pin 5 ?2 external diameter, upper pin 5 ?2 needle point 5 ?5 parts be positioned at through hole but can not described through hole be passed, thus make pin 5 ?2 pairs of cover plates also have a supporting role.
And the cover plate shape of decision design---polygon and the structure of middle with hole, experiment shows, after have employed air pressure balance means, this decision design, the air pressure inside and outside mixed medicine glass can be allowed faster to reach balance, thus in wet heating sterilization process, showing more outstanding---diaphragm seal is as before smooth, and mixed medicine glass is not at all out of shape.This is because polygon and the cover plate of middle with hole, can add under large cover and the atmosphere exchange rate in region on cover plate, can allow air pressure equalisation in mixed medicine glass faster, allow mixed medicine glass other balances inside and outside.
