Abstract
The utility model discloses a double-needle mixing drugs mouth with a spiral-push-type needle point protective casing. A double-needle is composed of a needle seat, an upper needle and a lower needle. A mixing drugs body of cup body structure is formed extending by the edge of the needle seat along the upper needle direction. An inner sleeve and an outer sleeve are sleeved outside the lower needle, wherein external threads are disposed on the outer wall of the inner sleeve, a needle point of sealed structure is disposed at the bottom port of the inner sleeve, and internal threads are disposed on the inner wall of the outer sleeve. One end of the outer sleeve is fixed on the needle seat and the other end of the outer sleeve is spun on the inner sleeve. Before drugs mix, the inner sleeve is spun at the bottom of the outer sleeve and a protective casing of the lower needle is formed by the inner sleeve and the outer sleeve. During drugs mix, people need to impale a sealing plug in a sealing cover of an infusion soft bottle or an infusion soft bag by the needle point at the bottom of the inner sleeve, tear open a sealing membrane disposed at the upper port of the mixing drugs body, impale a sealing cover of a penicillin bottle by the upper needle, spin the mixing drugs body downward, spin the inner sleeve into the outer sleeve, impale the tip of the needle point at the bottom of the inner sleeve, and squeeze the infusion soft bottle or the infusion soft bag, consequently the drugs can be mixed with solutions. Drugs mix operation is more simple and time-saving.

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, have the crosspointer medicine mixing mouth of screw-pushing type needle point protective sleeve, this crosspointer by needle stand 1, go up pin 2 and following pin 3 is formed.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; The outer wall of interior cover 11 is provided with external screw thread, and the bottom nozzle of interior cover 11 is provided with the needle point 13 of hermetically-sealed construction, and the inwall of overcoat 12 is provided with female thread; One end of overcoat 12 is fixed on the needle stand 1, and the other end screws on interior cover 11 through threaded engagement.
The tip of needle point 13 has pin hole 14, and the cross section of interior cover 11 is provided with barrier film 15, and barrier film 15 is between the needle point and pin hole 14 of following pin 3, and is as shown in Figure 1.This crosspointer medicine mixing mouth that has screw-pushing type needle point protective sleeve is before mixing medicine, and following pin 3 is positioned at the needle point 13 of cover 11, cover bottom and the protective sleeve that overcoat 12 is formed hermetically-sealed construction, and the sharp degree of the needle point of following pin 3 is protected effectively.When mixing medicine; Needle point 13 with interior cover 11 bottoms pierces through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8 earlier, is rotated down and mixes medicine body 4, cover 11 precessions in overcoat 12 in making; The tip of following pin 3 diaphragm 15 and needle point 13, and be communicated with transfusion flexible bag or soft transfusion bottle.
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.
The port of mixing medicine body 4 is provided with diaphragm seal 5, and crosspointer, mixed medicine body 4, interior cover 11 and overcoat 12 are encapsulated in the outer package.Before mixing medicine; In the following pin protective sleeve of the hermetically-sealed construction formed of cover 11, the needle point of interior cover bottom and overcoat 12 cooperate outer package (like sealing bag) to use; 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 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.
For the structure of interior cover bottom needle point, except that adopting structure as shown in Figure 1, also can adopt structure as shown in Figure 2, the tip of the needle point 13 of interior cover 11 bottoms is a hermetically-sealed construction.When mixing medicine; Earlier needle point 13 is pierced through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8, be rotated down again and mix medicine body 4, cover 11 precessions in overcoat 12 in making; Following pin 3 pierces through the tip of needle point 13, can realize down that equally pin 3 is communicated with transfusion flexible bag or soft transfusion bottle.
When using this crosspointer medicine mixing mouth that has screw-pushing type needle point protective sleeve, as shown in Figure 3, can be earlier the needle point 13 of interior cover bottom be pierced through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag; Tear and mix the diaphragm seal 5 that medicine body 4 port are provided with; Last pin 2 is pierced through the sealing-plug of cillin bottle, be rotated down then and mix medicine body 4, cover 11 precessions in overcoat 12 in making; Make down pin 3 puncture the barrier film 15 of below and the tip of needle point 13, and be communicated with transfusion flexible bag or soft transfusion bottle; 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.
