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, omnidistance screw thread precession prepackage type drug feeding device comprises adding cartridge case 1, dosing crosspointer 2, interior cover 4 and overcoat 5.An end that adds cartridge case 1 is an interface link 6; Dosing crosspointer 2 is located at through crosspointer supporting seat 7 and adds in the cartridge case 1 and can be along adding moving axially of cartridge case 1; Medicament reservoir 3 is placed on when adding in the cartridge case 1; One needle point of dosing crosspointer 2 is corresponding with interface link 6, and another needle point of dosing crosspointer 2 is corresponding with medicament reservoir 3.The cross section of inboard wall of interior cover 4 is provided with a diaphragm seal 8, and the outer wall of interior cover 4 is provided with external screw thread, an end of interior cover 4 and the other end sealed butt joint (can adopt the mode of seam) that adds cartridge case 1.The sealing of one end of overcoat 5 is provided with female thread on the inwall of its external sleeve 5, overcoat 5 through the threaded engagement rotation set on interior cover 4, the blind end of its external sleeve 5 be provided with one stretch to diaphragm seal 8 depression bar 9.Also can on the top exterior walls that adds cartridge case 1, external screw thread be set, overcoat 5 rotation sets are being added on the cartridge case 1.
The position (as being set to thin film) that is prone to expose can be adopted in the middle part of sealing film 8, after depression bar 9 presses on the sealing film, at first exposes the middle part of sealing film, directly presses on the infusion vessel 12 then.Certainly, diaphragm seal 8 also can adopt sealing elastomeric membrane, infusion vessel 12 be pre-loaded into add in the cartridge case 1 after, depression bar 9 presses on the infusion vessel 12 through the sealing elastica.
When this whole process screw thread precession prepackage type drug feeding device and infusion vessel assembling, interface link 6 seam that at first will add cartridge case 1 are on the interface on the infusion vessel 12 13; Again dosing crosspointer 2 is snapped in and add in the cartridge case 1; Dosing crosspointer 2 is fixed through crosspointer supporting seat 7 and the friction that adds between cartridge case 1 inwall, certainly, also can support dosing crosspointer 2 through the support bar of frangible; Only need support bar is arranged on the bottom of crosspointer supporting seat 7 and supports crosspointer supporting seat 7; In the process that dosing crosspointer 2 moves down, crosspointer supporting seat 7 at first breaks support bar, and dosing crosspointer 2 just can move down smoothly; Then medicament reservoir 3 is placed on and adds in the cartridge case 1; Because of being arranged with at least two elasticity cards 10 (in the present embodiment on the inwall that adds cartridge case 1; Add on the inwall of cartridge case 1 and be arranged with four elasticity cards); Medicament reservoir 3 is supported on (being that elasticity card 10 is stuck between the bottle cap and body of medicament reservoir 3) on the elasticity card 10, makes the position relative fixed of medicament reservoir 3; And then with interior cover 4 seam on the other end that adds cartridge case 1; At last with overcoat 5 rotation sets on interior cover 4, if external screw thread is arranged on and adds on the cartridge case 1, only need overcoat 5 rotation sets just can adding on the cartridge case 1.
In be respectively equipped with the zigzag of falling that prevents reverse rotation and only block 11 and (be arranged on like external screw thread and add on the cartridge case 1 on cover 4 the external screw thread with on the female thread of overcoat 5; Then only need on the external screw thread that adds cartridge case 1, to be provided with the zigzag of falling that prevents reverse rotation and end card); Its external sleeve 5 rotation sets are after on the interior cover 4; Only block 11 and on reverse, have barrier effect because of falling zigzag, overcoat 5 can only be rotated down along interior cover 4, promptly guaranteed can not move backward at mixed medicine process Chinese medicine container 3.The interface link 6 that adds cartridge case 1 forms a throat structure, is more conducive to the interface size coupling with infusion vessel (being transfusion flexible bag or soft transfusion bottle) like this.
When use should whole process screw thread precession prepackage type drug feeding device; The interface link of cartridge case 1 and interface 13 sealed butt joint of infusion vessel 12 will be added earlier and (mode of seam can be adopted; Also can adopt the mode that is threaded), in the present embodiment, infusion vessel 12 adopts transfusion flexible bag; As shown in Figure 2; Medicament reservoir 3 is pre-loaded into adds in the cartridge case 1, make medicament reservoir 3 and dosing crosspointer 2 be in sealing state through barrier film in the interface 13 14 and diaphragm seals 8 on the interior cover 4, thereby make medicament reservoir be in aseptic condition in transportation with in storing.When mixing medicine, rapid rotary sleeve 5, depression bar 9 moves down and exposes the middle part of diaphragm seal 8; Directly be pressed on the medicament reservoir 3; And promote medicament reservoir 3 and move down, and then promote dosing crosspointer 2 and move down, when the last needle point of dosing crosspointer 2 pierces through the sealing-plug on the medicament reservoir 3; The following needle point of dosing crosspointer 2 punctures the barrier film 14 in the interface 13; Make that moment is communicated with in medicament reservoir 3 and the transfusion flexible bag, whole process all belongs to aseptic butt joint, and whole process all is rotated down realization (promptly realizing omnidistance screw thread precession) through overcoat 5 on interior cover 4.And helicitic texture can prevent transportation and store, depression bar breakseal film or compressing infusion vessel, therefore, this whole process screw thread precession prepackage type drug feeding device can realize medicine transportation, storage, butt joint, mix medicine and transfusion overall process sterile closed.
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.
