Detailed description of the invention
embodiment 1
See Fig. 1 and Fig. 2: this utility model is obstructed lacrimal passage therapeutic apparatus, it comprises syringe 1 and loading mechanism 2.This loading mechanism 2 is when carrying out treatment operation, and be just connected and be fixed on the front end aperture 14 of syringe 1, when non-treatment, loading mechanism 2 can depart from from the front end aperture 14 of syringe 1, thus sterilizes accordingly or preferentially change.Now to their concrete structure and mutually connected structure be described in detail as follows.
Syringe 1 forms primarily of syringe 11, piston rod 12, piston 13 and front end aperture 14, the size dimension of syringe 11 is rationally determined according to medical instructions for use, piston 13 is filled in syringe 11 by piston rod 12, and front end aperture 14 is axial arranged to communicate with syringe 11 inner chamber in the front end surface of syringe 11.Visible, said injector device 1 is unanimously to common medical syringe.
In order to avoid untapped syringe 1 inner chamber and institute's drug storage liquid contaminated, said syringe 1 also includes gag 15.This gag 15 adopts flexible rubber to make usually, and it has the projection of coupling syringe front end aperture 14 internal diameter profile, and this gag 15 is fixed on front end aperture 14 root of syringe 1 by the flexible chain portion suit of one.Before not connecting loading mechanism 2, the front end aperture 14 of syringe 1 blocks shutoff by gag 15; Syringe 1 preparation or when having connected loading mechanism 2, gag 15 lifts out from front end aperture 14, is fastened on the front end aperture 14 of syringe 1 by flexible chain portion.
In order to syringe 1 can be made reliably, to be firmly connected loading mechanism 2, said syringe 1 also includes locking nut 16.This locking nut 16 is sleeved on the front end aperture 14 of syringe 1, the root outer wall of front end aperture 14 have boss or the packing ring of limiting locking nut 16 the inner, the internal diameter of locking nut 16 slightly larger than the external diameter of front end aperture 14, usually should the external diameter of the corresponding front end aperture 14 loading hose 22(that adds loading mechanism 2 should refer to hose coupling 23 herein) wall thickness.When syringe 1 is connected loading mechanism 2, the loading hose 22 of loading mechanism 2 is sleeved on the front end aperture 14 of syringe 1, is overlapped and is pressed on loading hose 22, be close-coupled on front end aperture 14 by loading hose 22 by locking nut 16.When loading mechanism 2 departs from syringe 1, the loading hose 22 of locking nut 16 from institute's casing pressure is exited, and shut down loading hose 22 from front end aperture 14 pull-up of syringe 1.
Loading mechanism 2 be supporting give syringe 1 use, for be connected to syringe 1 front end aperture 14, to patient's lacrimal point delivering medicament, as can be seen here, during use, loading mechanism 2 is between syringe 1 and the lacrimal point of patient.
Loading mechanism 2 is formed primarily of punctum dilator 21, loading hose 22 and seal wire 24.Wherein, punctum dilator 21 adopts the product of existing maturation, the front end of this punctum dilator 21 is used for the lacrimal point directly contacting patient, its rear end should have outer large, interior little stepped hole, the external diameter compared with diameter macropores coupling loading hose 22 of punctum dilator 21 rear end, the diameter of the smaller hole diameter coupling seal wire 24 of punctum dilator 21 rear end.Punctum dilator 21 is connected loading hose 22 by seal wire 24.
Loading hose 22 adopts adiabatic transparent material to make, and its length is 50 ~ 80mm(such as 50mm, 65mm or 80mm etc.), internal diameter is 0.4 ~ 0.8mm(such as 0.4mm, 0.6mm or 0.8mm etc.), external diameter is 0.5 ~ 1mm(0.5mm, 0.7mm or 1mm etc.).In order to ease of use, the volume scale that mutual correspondence, coupling are set on the syringe 11 of loading hose 22 and syringe 1 can be considered.The back-end sealing of aforementioned loading hose 22 is connected with hose coupling 23, the inner surface contour of this hose coupling 23 is corresponding, front end aperture 14 outline of coupling said syringe 1, when loading mechanism 2 is connected on syringe 1, be engaged on the front end aperture 14 of syringe 1 by hose coupling 23.
The Main Function of seal wire 22 plays " trying to make a match " effect when being and assembling on punctum dilator 21 loading hose 22 of capillary, thus seal wire 24 should be that quality is soft, plasticity good, flexible hard seal wire, the iron wire that preferred phosphorus content is lower is (though steel wire can, but its hardness is higher, plasticity is poor, not easily meet the bending of rational demand).The external diameter of this seal wire 24 should mate the rear end diameter of bore of punctum dilator 21, also mate the internal diameter of loading hose 22 simultaneously, thus and foregoing known, the length of seal wire 24 is greater than the length of loading hose 22, and the diameter of seal wire 24 is consistent or be slightly less than the internal diameter of loading hose 22.
During use procedure of the present utility model: inject medicinal liquid and air-out in syringe 1; Seal wire 24 be inserted into the rear end of punctum dilator 21 and make punctum dilator 21 contact patient's lacrimal point; Loading hose 22 to be enclosed within seal wire 24 and to move forward along seal wire 24, until the front end of loading hose 22 is connected in the rear stomidium of punctum dilator 21; Extract seal wire 24 out, left unused; By hose coupling 23 loading hose 22 be connected and be fixed on the front end aperture 14 of syringe 1; Operating syringe 1, injects medicinal liquid in the lacrimal passage of patient; Take off therapeutic apparatus from patient body, carry out due sterilization, replacing or waste treatment.
embodiment 2
Other structure of the present embodiment is identical with embodiment 1, and difference is: indent die cavity gag with coupling syringe front end aperture outline, this gag covers on the front end aperture of syringe in the cap mode of buckleing.
embodiment 3
Other structure of the present embodiment is identical with embodiment 1, and difference is: gag and syringe are uncorrelated, separate configuration, and namely gag is not fixed on syringe, but gag is easily lost like this.
embodiment 4
Other structure of the present embodiment is identical with embodiment 1, difference is: syringe front end aperture does not have locking nut, the loading hose of loading mechanism by fastening the parts bandings such as rope, clip or clasp on the front end aperture of syringe, but its banding degree and convenience relatively limited.
The various embodiments described above only in order to this utility model to be described, are not intended to limit.Although be described in detail this utility model with reference to the various embodiments described above, those of ordinary skill in the art has been to be understood that: it still can be modified to the technical scheme of the various embodiments described above, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
