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 needle guard protective layer, 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.The infra pin 3 outer protection needle guards 11 that are with; Protection needle guard 11 is made up of telescopic section 12 and needle point section 13; Telescopic section 12 can adopt elastic bellows or corrugated tubing; The top of telescopic section 12 is fixedly connected with the bottom of needle stand 1, and the bottom of telescopic section 12 is fixedly connected with the top of needle point section 13, and the needle point of following pin 3 is corresponding with needle point section 13.
The tip of needle point section 13 has pin hole 14, and the endoporus cross section of needle point section 13 is provided with barrier film 15, and barrier film 15 is between the pin hole 14 of needle point that plays pin 3 and needle point section 13, and is as shown in Figure 1.This crosspointer medicine mixing mouth that has the needle guard protective layer is before mixing medicine, and telescopic section 12 is in elongation state, and following pin 3 is positioned at protection needle guard 11, and the sharp degree of the needle point of following pin 3 is protected effectively.When mixing medicine; Needle point section 13 with protection needle guard 11 pierces through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8 earlier, promotes downwards to mix medicine body 4 again, makes down the tip of pin 3 diaphragm 15 and needle point section 13; Telescopic section 12 is compressed; To go up the sealing-plug that pin 2 pierces through cillin bottle then, therefore, protection needle guard 11 can't influence pin 3 puncture through seal plugs down.
The port of mixing medicine body 4 is provided with diaphragm seal 5, and crosspointer, mixed medicine body 4 and protection needle guard 11 are encapsulated in the outer package.Before the use; Diaphragm seal 5 cooperates outer package (like sealing bag) to use with protection needle guard 11; Can make mixed medicine body 4 be in sealing state with crosspointer; Last pin 2 and the following pins in the protection needle guard 11 not only having kept mixed medicine body 4, mixed in the medicine body 4 have good cleannes before use, have also effectively protected the sharp degree of last pin 2 and following pin 3 and the internal structure of mixed medicine body 4, avoid the damage in the transportation; During use, take outer package apart, remove 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.
For the structure of protection needle guard, except that adopting structure as shown in Figure 1, also can adopt structure as shown in Figure 2, protection needle guard 11 also is made up of telescopic section 12 and needle point section 13, and the tip of needle point section 13 is a hermetically-sealed construction.When mixing medicine, earlier needle point section 13 is pierced through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8, promote to mix medicine body 4 downwards, the tip that makes down pin 3 pierce through needle point section 13, telescopic section 12 is compressed, and makes pin 2 pierce through the sealing-plug of cillin bottle then.
When using this crosspointer medicine mixing mouth that has the needle guard protective layer, as shown in Figure 3.Can earlier the needle point section 13 of protecting needle guard 11 be pierced through the sealing-plug 10 in the seal cover 9 on soft transfusion bottle or the transfusion flexible bag 8, tear and mix the diaphragm seal 5 that medicine body 4 port are provided with, last pin 2 pierced through the sealing-plug of cillin bottle; Promote downwards then to mix medicine body 4, telescopic section 12 is compressed, the tip of following pin 3 diaphragm 15 and needle point section 13, and be communicated with soft transfusion bottle or 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.
