The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
Fig. 1 is the structural representation of the bivalve lid of band crosspointer medicine mixing mouth, and Fig. 2 is a kind of structural representation of needle cylindrical unit and crosspointer resilient supporting unit, and is as shown in the figure.The bivalve lid of band crosspointer medicine mixing mouth comprises bivalve lid 1, medicine mixing mouth 4 and crosspointer 5.Have mixed medicine passage 2 and infusion channel 3 on the bivalve lid 1 (in this enforcement; Mixed medicine passage and infusion channel are located at the top of bivalve lid; The bottom of bivalve lid is and the connectivity port of the interface seam of infusion vessel that the bottom of mixing medicine passage and infusion channel is the hermetically-sealed construction identical with the lid material).Medicine mixing mouth 4 is made up of with needle cylindrical unit 42 mixed medicine card body 41, and the port of needle cylindrical unit 42 is connected with the port of mixed medicine passage 2 or is one-body molded.The structure of crosspointer 5 is as shown in Figure 3, and crosspointer 5 comprises the last pin 52 and following pin 53 of pedestal 51 and hollow structure.Last pin 52 and following pin 53 are located at the above and below of pedestal 51 respectively, and needle point is outside, and the inner chamber of the inner chamber of last pin 52 and following pin 53 communicates.The cross section of needle cylindrical unit 42 is provided with crosspointer resilient supporting unit 6, and crosspointer resilient supporting unit 6 is provided with a through hole 61 along the axis direction of needle cylindrical unit 42.Mix in the medicine passage 2 and be provided with sealing-plug 7, be provided with sealing-plug 9 in the infusion channel 3.When pedestal 51 was stuck in the through hole 61, following pin 53 was corresponding with the sealing-plug 7 in the mixed medicine passage 2.On the port of infusion channel 3, be provided with the sealing handle 10 of the port of opening this infusion channel 3, the bottom of sealing handle 10 is with the port sealing of infusion channel 3.
Mixed medicine passage 2 stretches out and forms an annular boss 8, and the port of needle cylindrical unit 42 is enclosed within on this annular boss 8 and with this annular boss 8 and is sealed and matched.The port of needle cylindrical unit 42 through the bottom is enclosed within and is prone on the annular boss 8 cooperate with the port sealing of mixed medicine passage 2.
In the present embodiment, the convexity 62 of a plurality of sawtooth pattern structures of the inner wall even distribution of crosspointer resilient supporting unit 6.When the pedestal 51 of crosspointer 5 is stuck in the through hole 61 of crosspointer resilient supporting unit 6; When in a single day pedestal 51 receives downward pressure; Because of convexity 62 has better elastic; The boss extruding in the position that just can concave, the indent position is that the boss of pressurized provides the space that is squeezed, and makes pedestal 51 under stress, pass the through hole 61 of crosspointer resilient supporting unit 6 more easily.
Certainly; The structure of pedestal 51 is not limited to the structure of Fig. 3, also can adopt the structure of Fig. 4, and the outer wall of pedestal 51 is uniformly distributed with the convexity 62 of a plurality of sawtooth pattern structures; During use; The pedestal 51 of sawtooth pattern structure is stuck in the through hole 61 of crosspointer resilient supporting unit 6, and tightly engagement between the convexity 62 of the sawtooth pattern structure that is uniformly distributed with on this inner hole wall, can pedestal 51 be stuck in the through hole 61 of crosspointer resilient supporting unit 6 equally.
The structure of crosspointer resilient supporting unit 6 also is not limited to said structure, also can adopt structure as shown in Figure 5.Several flexure strips 63 that are uniformly distributed with setting on the inwall circumference of crosspointer resilient supporting unit 6 by needle cylindrical unit 42 are formed, and several flexure strips 63 form through hole 61 on the axis of needle cylindrical unit 42.The pedestal 51 of crosspointer 5 is stuck in the through hole 61, and in a single day pedestal 51 receives downward pressure, flexure strip 63 downwarpings, and through hole 61 increases, and pedestal 51 can pass the through hole after this increase equally.
Symmetricly on the medial wall of medicine mixing mouth 4 be provided with at least two and be barb-like and be used to prevent the anti-slide fastener 43 that medicament reservoir lid withdraws from; In the present embodiment; Medicine mixing mouth 4 is made up of with needle cylindrical unit 42 mixed medicine card body 41, and anti-slide fastener 43 symmetries are located on the inwall that mixes medicine card body 41.After in medicament reservoir snaps in mixed medicine card body 41, anti-slide fastener 43 just can be firm medicament reservoir is connected to mixes in the medicine card body 41.
Be provided with seal cover 11 in the upper end of medicine mixing mouth 4 (being the upper end of the mixed medicine card body 41 in the present embodiment); Before the use; Seal cover 11 makes mixed medicine card body 41, the crosspointer 5 that is positioned at mixed medicine card body 41 and the needle cylindrical unit 42 of mixed medicine card body 41 bottoms be in sealing state, makes mixed medicine card body 41, dosing pin 5 and needle cylindrical unit 42 have good cleannes before use; During use, remove seal cover 11 and can use, both convenient, the cleannes that can guarantee to mix medicine card body 41, dosing pin 5 and needle cylindrical unit 42 again.
When using the bivalve lid of band crosspointer medicine mixing mouth, (the bivalve lid is divided into that the bivalve of be with inner cap covers and the bivalve that do not have an inner cap covers with the connectivity port of bivalve lid 1 bottom and the interface seam of infusion vessel; The mixed medicine channel bottom of the bivalve lid of no inner cap is the hermetically-sealed construction identical with the lid material; Therefore, sealing-plug is directly to contact with the solution in the infusion vessel), medicament reservoir is positioned in the medicine mixing mouth 4; Make the sealing-plug of the last tip alignment medicament reservoir of crosspointer 5; Push medicament reservoir downwards, the pedestal 51 of crosspointer 5 just can pass the through hole 61 of crosspointer resilient supporting unit 6, and last pin 52 penetrates the sealing-plug of medicament reservoir; Following pin 53 penetrates the hermetically-sealed construction that mixes medicine passage interior sealing-plug 7 and mixed medicine passage 2 bottoms, and the extruding infusion vessel just can be with solution in the infusion vessel and the medicament mixed in the medicament reservoir.During transfusion, only need break the sealing handle 10 on infusion channel 3 ports into two with one's hands, the sealing-plugs 9 in the infusion channel 3 expose, and sealing-plug 9 and the hermetically-sealed construction of infusion channel 3 bottoms that transfusion needle pierces through in this infusion channel 3 just can be infused.Whole process, medicament reservoir can mix through once contacting of short time with infusion vessel, good sealing effect not only, and use more convenient, quick, much cleaner.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
