The specific embodiment

Please referring to Figure 1 and Figure 2, compression type medicament mixing arrangement of the present utility model includes a notes pipe 10, one cartridge case 20, body 40 is blocked in a pushing and pressing part 30 and two, wherein:

These notes pipe 10 1 ends are formed with geat 11, and this geat 11 can connect an injection head (not shown); And this notes pipe 10 other ends are formed with and are junction surface 13 cylindraceous, are laid with screw thread on these junction surface 13 internal faces; These notes pipe 10 inside are formed with runner 12, are provided with the vane axle 14 of surperficial tool helical form blade in this runner 12;

This cartridge case 20 corresponds to junction surface 13 and is formed with and is conjugation tube 21 cylindraceous with respect to annotating pipe 10 1 ends, and these conjugation tube 21 outside wall surface are provided with screw thread and can be screwed with junction surface 13; These cartridge case 20 inside are formed with two rooms 23 that store different medicaments respectively, form the perforate 230 that communicates with runner 12 on these two rooms, 23 1 end wall surface respectively, and the outstanding protuberance 24 that is formed with between this perforate 230, this protuberance 24 is the ends that push against in aforementioned vane axle 14, prevents that vane axle 14 from producing displacement in runner 12; In addition, these two rooms, 23 other ends are formed with opening 231 respectively, in this opening 231 respectively driving fit be provided with a cock body 22, make the medicaments in this room 23 can not flow out by opening 231, wherein these cock body 22 1 ends are formed with engagement groove 220;

This pushing and pressing part 30 includes two push rods 31 that branch is arranged, this two push rod 31 is to be parallel to each other and tool one fastens end and can penetrate in the engagement groove 220 of cock body 22 fixing, so that being formed with a disk body 32, the slippage in room 23 of pushing and pressing cock body 22, one end this pushing and pressing part 30 is pushed for user; In addition, wherein be connected with a fixture block 33 via a limit portion 330 on the contiguous side surface that fastens end of this push rod 31, this fixture block 33 can support sincere in opening 231 outer rims of cartridge case 20, penetrates among the room 23 to limit this push rod 31; During use, must the first application of force make 330 fractures of limit portion and fixture block 33 disengaging push rods 31 normally use, reach whereby and distinguish new product whether function;

This blocks body 40 is to be the dome-shaped lamellar body respectively, it is the made elastomers of soft materials such as rubber, it is arranged at each room 23 1 end respectively, be positioned at perforate 230 places of each room 23, isolated whereby this runner 12 is closed state with each room 23, makes medicament seal up for safekeeping among each room 23, wherein, this blocks and is formed with a profile groove 41 on the surface of body 40 with respect to perforate 230, and these profile groove 41 inner bottom surfaces form thin-walled design.

Please cooperate referring to shown in Figure 4, in another preferred embodiment of the present utility model, aforementioned body 40 surfaces of blocking are formed with symmetrical up and down profile groove 41 ', form thin-walled between this profile groove 41 ' again.Whereby, then this blocks body 40 and can reach normal effect towards being arranged at each room 23 1 end respectively arbitrarily, and is more convenient in the use.

Please referring to shown in Figure 3, when compression type medicament mixing arrangement of the present utility model uses, directly the application of force is pushed pushing and pressing part 30 to promote push rod 31, make the medicament in the room 23 be exerted pressure in the surface of blocking body 40, after pressure surpasses to a certain degree, this profile groove 41,41 ' that blocks body 40 will break and form and penetrate, and medicaments in the room 23 be mixed among flowing into runner 12, thereby reach its medical effect.

In addition, the aforementioned profile groove 41,41 ' that blocks on the body 40 also can be and penetrates, and so then profile groove 41,41 ' internal face can be tight against mutually and reach airtight, and passes through compressive deformation and form the slit and flow out for the medicaments in the room 23.

From the above, compression type medicament mixing arrangement of the present utility model need not remove or moves before use blocking body 40, and to the greatest extent directly the application of force be pushed the outflow that medicament can be reached in pushing and pressing part 30, so use upward more convenient.In addition aforementioned block body 40 installings after, can reach running separately, need not cooperate other mechanism that is provided with in addition of utilization, therefore more simple on the structure, can effectively save manufacturing cost.
