Abstract
The utility model discloses an ophthalmic medicine ration injection device belongs to the ophthalmology nursing and uses the utensil field, and its structure includes: shell, piston, handle, push -and -pull ring, the shell is the pipe structure, and shell one end is equipped with toper binding off structure, and the shell other end is equipped with annular handle structure, shell hole and piston cooperation, piston one end is conical most advanced structure, the most advanced structure appearance of piston equals with the inner space volume of shell toper binding off structure that the shape is the same, and the piston other end is equipped with the push -and -pull ring. The utility model discloses simple structure, convenient operation, the spray volume that can realize at every turn instiling is the definite value, and spray volume that the control of can being more convenient for was instiled avoids the injury that excessively causes, equals the same design of shape through the inner space volume with the help of the most advanced structure appearance of piston and shell toper binding off structure, can realize the ration extraction and ration injection of liquid medicine, fine overcome the unable precise and quantitative volume of traditional injection device and get the problem of injecting of following.
Description
Technical field
This utility model relates to medicament for the eyes quantitative injection device, belongs to ophthalmic nursing fixture fields.
Background technology
Collyrium is one of the most frequently used pharmaceutical dosage form of ophthalmic diseases, and for much oculopathy, collyrium has directly, therapeutical effect efficiently.Along with the life style of people and the change of working condition, get more and more with the time of eye, such as see computer for a long time, see TV, operate video games etc., be easy to suffer from visual fatigue disease and xerophthalmia.These two kinds of diseases all with the dry and astringent discomfort of eyes for main manifestations, so collyrium becomes daily " required medicines " by a lot of people.Collyrium in fact, be in principle can just need not, there is no need conventional use.
The instillation of current collyrium is all armrest sense, cannot realize quantitatively, and sufferer can have a mind to many dropping eye drops usually in order to be effective, and too much instillation can cause unnecessary damage.
Utility model content
This utility model is all armrest sense for the instillation of current collyrium, cannot realize quantitatively, and sufferer can have a mind to many dropping eye drops usually in order to be effective, and too much instillation can cause the problem of unnecessary damage, devises medicament for the eyes quantitative injection device.
The technical scheme in the invention for solving the technical problem is:
This medicament for the eyes quantitative injection device, its structure comprises: shell, piston, handle, push-and-pull ring; Shell is circular tube structure, shell one end is provided with taper closing-in structure, the shell other end is provided with ring pull structures, shell endoporus coordinates with piston, described piston one end is conical tip structure, described piston tip construction profile is identical with the inner space volume equal shape of shell taper closing-in structure, and the piston other end is provided with push-and-pull ring.
Described push-and-pull ring is circulus, is provided with the borehole structure, push-and-pull ring one end and the piston one end integral structure that hold finger.
Described piston is cylindrical structural, and piston is arranged in shell endoporus, and piston and shell endoporus are interference fit.
Described shell one end and ring pull structures are integral type structure.
Described outer shell outer wall is provided with the scale of display medicinal liquid volume, and shell is transparent plastics material.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, easy to operate, can realize each dripping liquid medicine amount is definite value, can be more convenient for control instil amount of liquid medicine, avoid the excessive injury caused, by by the design identical with the inner space volume equal shape of shell taper closing-in structure of piston tip construction profile, quantitative extraction and the calibrated shot of medicinal liquid can be realized, well overcome conventional injection units and cannot measure the problem of following injection by accurate quantification.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure figure.
In figure: 1 shell, 2 pistons, 3 handles, 4 push-and-pull rings, 5 medicinal liquids.
Detailed description of the invention
As shown in Figure 1: medicament for the eyes quantitative injection device, its structure comprises: shell 1, piston 2, handle 3, push-and-pull ring 4; Shell 1 is circular tube structure, shell 1 one end is provided with taper closing-in structure, shell 1 other end is provided with ring-shaped handle 3 structure, shell 1 endoporus coordinates with piston 2, described piston 2 one end is conical tip structure, described piston 2 cutting-edge structure profile is identical with the inner space volume equal shape of shell 1 taper closing-in structure, and piston 2 other end is provided with push-and-pull ring 4; Described push-and-pull ring 4 is circulus, is provided with the borehole structure holding finger, push-and-pull ring 4 one end and piston 2 one end integral structure; Described piston 2 is cylindrical structural, and piston 2 is arranged in shell 1 endoporus, and piston 2 and shell 1 endoporus are interference fit; Described shell 1 one end and ring-shaped handle 3 structure are integral type structure; Described shell 1 outer wall is provided with the scale of display medicinal liquid 5 volume, and shell 1 is transparent plastics material.
Medicament for the eyes quantitative injection device described by the present embodiment, during use, in shell 1, quantitative liquid medicine 5 is extracted by piston 2, then the taper closing-in structure be provided with shell 1 one end aims at eyes affected part, the reach of piston 2 is now realized by push-and-pull ring 4, the calibrated shot of medicinal liquid is realized according to the scale on shell 1 surface, this utility model structure is simple, easy to operate, can realize each dripping liquid medicine amount is definite value, can be more convenient for control instil amount of liquid medicine, avoid the excessive injury caused, by by the design identical with the inner space volume equal shape of shell 1 taper closing-in structure of piston 2 cutting-edge structure profile, quantitative extraction and the calibrated shot of medicinal liquid can be realized, well overcome conventional injection units and cannot measure the problem of following injection by accurate quantification.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that this utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
