The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
As shown in Figure 1, plug-in crosspointer medicine mixing mouth, this crosspointer is made up of needle stand 1, last pin 2 and following pin 3.Last pin 2 and play pin 3 are arranged on the both sides of needle stand 1, and last pin 2 and following pin 3 are hollow structure and are interconnected, and pin 2 directions that make progress along the edge of needle stand 1 extend to form the mixed medicine body 4 of a cup body structure.Cover 11 and overcoat 12 in infra pin 3 outer being with; In cover 11 outer wall be provided with two rows along the location snap ring 13,14 that circumferentially is provided with, the inwall of overcoat 12 is provided with at least one row along circumferentially being provided with and being used the draw-in groove that plays the role of positioning with location snap ring 13,14 on the interior cover 11; One end of overcoat 12 is fixed on the needle stand 1, slidably cooperates in the axial direction on the cover 11 and with interior cover 11 in the other end is enclosed within.
In the present embodiment, the inwall of overcoat 12 is provided with two rows along circumferentially being provided with and being used the draw-in groove 15,16 that plays the role of positioning with two registration snap rings 13,14 on the interior cover 11.When this plug-in crosspointer medicine mixing mouth was vertically placed, the Reference numeral of going up a registration snap ring most on the interior cover 11 was 13, and the Reference numeral of next registration snap ring is 14; The Reference numeral of going up row's draw-in groove most on the overcoat 12 is 15, and the Reference numeral of next row's draw-in groove is 16.Before mixing medicine, interior cover 11 is outer goes up next row's draw-in groove 16 that a registration snap ring 13 is positioned at overcoat 12, pin protective sleeve under interior cover 11 is formed with overcoat 12, and following pin 3 is positioned at protective sleeve, can following pin 3 effectively be protected; When mixing medicine; Only need interior cover 11 is promoted in overcoat 12; In making outer next the registration snap ring 14 of cover 11 be positioned at overcoat 12 next arranges draw-in groove 16; In the outer registration snap ring 13 of going up of cover 11 be positioned at going up of overcoat 12 and one arrange draw-in groove 15, thereby make down pin 3 puncture below barrier film 17 time, and pierce through the interior sealing-plug of seal cover on soft transfusion bottle or the transfusion flexible bag.
In order to realize both can before mixed medicine, protecting to following pin; Sealing-plug in the seal cover under can when mixing medicine, not hindering again on needle-penetration soft transfusion bottle or the transfusion flexible bag; Also can on the outer wall of interior cover 11, be provided with two and arrange the location snap ring 13,14 that is provided with along circumferentially, and the location snap ring 13,14 that is provided with on the inwall of its external sleeve 12 on a row and the interior cover 11 is used the draw-in groove that plays the role of positioning.Before mixing medicine, interior cover 11 is outer goes up the draw-in groove that a registration snap ring 13 is positioned at overcoat 12, pin protective sleeve under interior cover 11 and overcoat 12 compositions; When mixing medicine, cover 11 promotes to overcoat 12 in only need making, and outer next the registration snap ring 14 of cover 11 is positioned at the draw-in groove of overcoat in making, thus make down pin 3 puncture below puncture through seal plug barrier film 17 time.Certainly; Be equal to replacement as present embodiment a kind of; Also but the inwall of its external sleeve 12 is provided with two rows along the draw-in groove 15,16 that circumferentially is provided with; And be used the location snap ring that plays the role of positioning with draw-in groove 15,16 on the inwall of overcoat 12 being provided with a row or two rows on the outer wall of interior cover 11, and can realize equally mixing before the medicine pin is down protected, do not hinder down the effect of needle-penetration when mixing medicine.
Last pin 2 and play pin 3 be all along the axis setting of the mixed medicine body 4 of cup body structure, snaps in when mixing in the medicine body 4 at cillin bottle 7, and last pin 2 is from the middle part insertion cillin bottle 7 of the seal cover of cillin bottle 7, and it is inclined to one side to avoid pin 2 to sting.
In cover 11 cross section be provided with barrier film 17, and barrier film 17 is positioned at the below of pin 3 down, the port of mixing medicine body 4 is provided with diaphragm seal 5, crosspointer, mixes medicine body 4, interior cover 11 and overcoat 12 and is encapsulated in the outer package.Before mixing medicine; Diaphragm seal 5 and interior cover 11 cooperate outer package (like sealing bag) to use with the following pin protective sleeve that overcoat 12 is formed; Can make mixed medicine body 4 be in sealing state with crosspointer; Not only keep mixed medicine body 4, gone up pin 2 and play pin 3 has good cleannes before use, also effectively protected the sharp degree of last pin 2 and following pin 3 and the internal structure of mixed medicine body 4, avoided the damage in the transportation; During use, take outer package apart, tear diaphragm seal 5 and get final product.
On the inwall that mixes medicine body 4, being symmetrically arranged with at least two is barb-like and is used to prevent the anti-slide fastener 6 that cillin bottle is loosening.In the present embodiment, on the inwall that mixes medicine body 4, be symmetrically arranged with six anti-slide fasteners 6.Cillin bottle 7 snap in mix in the medicine body 4 after, cillin bottle 7 can effectively avoid cillin bottle 7 in mixed medicine body 4, to withdraw from or become flexible to opposite direction under the inhibition of anti-slide fastener 6.
When using this plug-in crosspointer medicine mixing mouth, as shown in Figure 2, at first, take outer package apart, tear the diaphragm seal 5 that mixes medicine body 4 port, last pin 2 is pierced through the sealing-plug of cillin bottle 7; Again interior cover 11 bottoms are propped up the seal cover 9 on soft transfusion bottle or the transfusion flexible bag and promote cillin bottle 7; Cover 11 promotes in overcoat 12 in making; In outer next the registration snap ring 14 of cover 11 be positioned at overcoat 12 next arranges draw-in groove 16; In the outer registration snap ring 13 of going up of cover 11 be positioned at going up of overcoat 12 and one arrange draw-in groove 15, below following pin 3 punctures barrier film 17 time, and pierce through the interior sealing-plug 10 of seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8; Push transfusion flexible bag or soft transfusion bottle at last the medicine in the cillin bottle is mixed with transfusion flexible bag or the interior solution of soft transfusion bottle, it is simpler to mix the medicine operation, more saves time.
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.
