Specific implementation method
In the following, the present invention is further detailed in conjunction with Figure of description.
First embodiment
As shown in Figure 1, include pedestal 2, mix medicine glass 3, diaphragm 8 and mixed medicine channel 7, it is above-mentioned by pedestal 2, mixed medicine glass 3, every
The medicine mixer body construction that film 8 and mixed medicine channel 7 are constituted is formed in a manner of integrally formed.
Rubber plug 6 is placed in mixed medicine channel, is located on diaphragm 8.
Elastic clamp seat 4 as described in Figure 3 is placed in mixed medicine glass, and cross needle 5 as shown in Figure 4-8 is placed in elastic clamp seat
In 4, to form medicine mixer as shown in Figure 9, elastic clamp seat 4 and cross needle 5 after the installation is completed, in the rim of a cup of mixed medicine glass 3
Position of sound production has cover board 12, and then covering sealing film 13 is sealed mixed medicine glass.
It, can also be it is understood that infusion channel 11, can be integrally formed together with above-mentioned medicine mixer body construction
Using other infusion connector when soft bag bag making.
Mixed medicine channel 7 passes through the bottom of a cup 3-2 that pedestal 2 upwardly extends straight-through mixed medicine glass 3, and the effect of diaphragm 8 is isolation medical fluid
With directly contacting for rubber plug, accomplish to be fully sealed using preceding, can theoretically be located at appointing in the mixed medicine channel under rubber plug 6
What position, for example Fig. 1, diaphragm 8 is tightly attached under rubber plug 6 shown in 11；Or as shown in Fig. 9,12,13, diaphragm 8 is located at
Position under rubber plug.But in view of causing the knit stitch 5-3 of cross needle 5 too long if 8 position of diaphragm is too low, so
Preferably diaphragm 8 is located under rubber plug 6 and is close to the lower surface of rubber plug 6.
Rubber plug 6 is placed in mixed medicine channel, on diaphragm.The effect of rubber plug be guarantee knit stitch 5-3 puncture rubber plug 6 with every
After film 8, medical fluid is unlikely to ooze out mixed medicine channel after flowing out in the gap between diaphragm 8 and knit stitch 5-3 outer wall, that is,
It says, the outer diameter of rubber plug 6 and the internal diameter in mixed medicine channel match, so that rubber plug 6 and mixed medicine channel are in close contact.
Preferably, 6 upper surface of rubber plug and the upper surface bottom of a cup 3-2 are substantially flush or slightly above upper surface, in this way, such as
The lower surface of elastic clamp seat 4 shown in Fig. 3, pushes down the upper surface of rubber plug 6.
As a preferred technical solution, diaphragm 8 is located under rubber plug 6 and is close to the lower surface of rubber plug 6, Ke Yigeng
Good prevents medical fluid from penetrating into mixed medicine channel after lower needle-penetration diaphragm.Especially, rubber plug surface as described in Figure 2 is equipped with by convex
The relatively thin paracentesis area 6-1 that ring or groove 6-2,6-3 are limited, on rubber plug bulge loop or groove it is opposite, 8 upper surface of diaphragm
Corresponding position also is provided with groove or bulge loop.It is readily apparent that bulge loop or groove on rubber plug and groove on diaphragm 8 or convex
Ring is mutually chimeric, to achieve the purpose that preferably to prevent Drug leakage.
It is provided with the rubber plug 6 and diaphragm 8 of mutually chimeric groove or bulge loop, one is formed to rubber plug 6 in elastic clamp seat 4 and is squeezed
After pressure effect, the leakage of medical fluid after mixed medicine can be prevented completely.
For elastic clamp seat 4 as shown in Figure 3, including a snap ring 4-6, it is provided with elastic card claw 4-1 on the downside of the snap ring,
Snap ring described in the elastic card 4-1 upper end edge is evenly arranged and fixes, and the lower end the elastic card claw 4-1 is free end, and described
Elastic card claw is in the mixed medicine glass center incline structure from the fixed upper end to the free lower end.The elastic card
Seat tool has integrally formed bottom plate 4-5, support column 4-4, snap ring 4-6 and the periphery elastic card claw 4-1, the bottom plate 4-5 to be provided with
Support column 4-4 forms support to the snap ring 4-6 and fixes.
The bottom plate 4-5 is equipped with centre bore 4-3, and the knit stitch 5-3 passes through the centre bore to be formed to the crosspointer
Positioning.A circle annular projection 4-2, after elastic clamp seat 4 is installed in mixed medicine glass, bullet are provided with around centre bore 4-3
Property deck 4 on annular projection 4-2 can to rubber plug formed a squeezing action.
Restriction protrusion (not shown) is provided on the inner wall of the wall of cup 3-1, the elastic clamp seat 4 is installed on the mixed medicine
It is limited in cup by the restriction protrusion.
Crosspointer 5 as described in Fig. 4-8, needle plate 5-1 are installed under the elastic card claw 4-1 in the mixed medicine glass,
On bottom plate 4-5.Crosspointer 5 includes integrally formed hollow upper needle 5-2 and knit stitch 5-3 and is combined into upper needle and knit stitch
The needle plate 5-1, upper needle 5-2 of one, the head knit stitch 5-3 are provided with needle point 5-5.
For crosspointer 5, the outlet 5-4 of the hollow channel of upper needle can be provided on the syringe needle side wall of the upper needle 5-2；
Likewise, the outlet of the hollow channel of the knit stitch, is provided with (not shown) on the syringe needle side wall of the knit stitch 5-3.So set
It sets, is in order to avoid upper needle, knit stitch are when puncturing rubber plug, bottle stopper, the edge of outlet forms directly cutting to plug and generates big
The clast of amount.It is arranged on the side wall of syringe needle by that will export, needle point is directly pierced into rubber plug, not will form directly cutting and is made
With reducing the generation of clast.
Or as Figure 7-8, upper needle is coated with one layer of elastic contraction film, and elastic contraction film is pressed after piercing
Contracting, is deposited in around puncturing hole, so as to effectively prevent medical fluid to come out along the gap leakage of puncturing hole.It is readily apparent that
Knit stitch can equally coat one layer of elastic contraction film, to solve the problems, such as that medical fluid is leaked along the gap of puncturing hole.
Combination for crosspointer 5, elastic clamp seat 4 and mixed medicine glass 3, pedestal 2 mixes medicine glass and pedestal one as described in Figure 9
Molding, and elastic clamp seat 4 is placed in the 3 of mixed medicine glass, crosspointer 5 is fastened in elastic clamp seat 4.
Specifically, after elastic clamp seat 4 is placed in mixed medicine glass 3, the restriction protrusion that is arranged on the inner wall of wall of cup 3-1
(not shown) limits, so that elastic clamp seat 4 will not skid off mixed medicine glass after placing.In addition, elastic clamp seat 4 is limited
The position of system enables the bottom of elastic clamp seat 4 to contact the bottom of a cup 3-2 of the mixed medicine glass 3.In the setting side of preferred rubber plug 6
In case, the annular projection 4-2 of 4 bottom of elastic clamp seat, which can be formed rubber plug 6, to be squeezed.
The crosspointer 5 being installed among elastic clamp seat 4, the needle plate 5-1 of crosspointer 5 be located at elastic card claw 4-1 and bottom plate 4-5 it
Between, after being provided with, knit stitch 5-3 does not pierce through rubber plug 6.
It is of course also possible to understand, before the use, knit stitch 5-3 is partially penetrated into rubber plug 6, or right as shown in Figure 9
Rubber plug 6 punctures completely, or more preferably an aperture is preset at 6 center of rubber plug, forms annular rubber plug, and knit stitch 5-3 passes through
Aperture punctures rubber plug 6, is feasible scheme.When design circularizes rubber plug, rubber plug central small hole diameter is smaller than knit stitch 5-3,
So that knit stitch 5-3 not will form dissection to rubber plug 6 after knit stitch 5-3 is inserted into the aperture in rubber plug 6 and passes through rubber plug 6, thus
Knit stitch 5-3 can be effectively avoided to form micro- bits pollution caused by medical fluid when puncturing rubber plug 6.Moreover, because under hole diameter ratio
The outer diameter of needle 5-3 is small, and rubber plug 6 can still be close to knit stitch 5-3 to avoid leakage.
As for the state used, as shown in Figure 14,15, cillin bottle 9 is inserted into mixed medicine glass 3, and the bottle cap of cillin bottle 9 is pressed into
In elastic clamp seat 4, so that the free end of elastic card claw 4-1 is located at the bottleneck of cillin bottle 9 and is stuck in the bottleneck, thus right
Cillin bottle 9 is stuck to be exited from mixed medicine glass 3.
Meanwhile the bottle cap of cillin bottle 9 is pierced through by upper needle 5-2, bottle cap pushes down on needle plate 5-1, so that knit stitch 5-3 be pushed to pierce
It wears rubber plug 6, then pierce through diaphragm 8, so that mixed medicine channel 7 is connected to by crosspointer 5 with cillin bottle.
It is readily apparent that the snap ring 4-6 internal diameter and cillin bottle outer diameter of elastic clamp seat 4 are almost the same, or slightly larger than described
Cillin bottle outer diameter.And cillin bottle 9 is limited in order to preferably fixed, so that cillin bottle 9 does not slide, the bottle cap thickness of cillin bottle 9
