Abstract

Existing dispenser is excessively flat small due to position limiting convex ring, and inconvenience is brought to hand-held use operation.The purpose of this utility model is to provide a kind of dispenser position limiting convex ring for being easy to hand-held, existing dispenser position limiting convex ring (5) shape and external diameter is improved, the position limiting convex ring outer (6) widened is easy to hand-held.In order to solve the medicine bottle that bulge loop external diameter matches existing market two kinds of bottlenecks of common size, position limiting convex ring (5) is fabricated to ellipticity, the external diameter of transverse is approached with big bottleneck medicine bottle diameter, and the external diameter of ellipse short shaft is approached with small bottleneck medicine bottle diameter.When using, due to bulge loop outer (6) widen be easy to it is hand-held, simultaneously, diameter due to ellipticity bulge loop outer (6) major axis and short axle external diameter respectively with vial size bottleneck is approached, can with finger easily while be affectedly bashful bulge loop and medicine bottle, fixed dispenser displacement pin (2) and medicine bottle are accurately made up a prescription.

Description

A kind of dispenser position limiting convex ring for being easy to hand-held

Technical field

The utility model belongs to technical field of medical instruments, and in particular to a kind of to have making up a prescription for handle and fixation function concurrently Device spacing ring, is allowed to facilitate hand-held to use.

Background technology

, there is the deficiencies such as cumbersome, the easy pollution of drug waste, process in traditional dosage.The applicant once disclosed Two kinds of (binary channels and single channel) dispenser (patent No.s：201220097375.0,201220240075.3), the dispenser can letter Change dispensing operation step, reduce medicament residue, but require dispenser and medicine bottle positioning it is fixed accurately can aspiration medicinal liquid it is clean, by It is excessively flat small in the dispenser position limiting convex ring described in the patent, and use dispenser puncture procedure when must it is hand-held herein, hardly possible In being affectedly bashful stress and easily slip, meanwhile, dispenser must be fixed on during dispensing operation at medicine bottle stopper, if bulge loop size with Medicine bottle bottleneck external diameter is inconsistent to be difficult to hand-held fixation, is made troubles to operating with.If changing position limiting convex ring shape and outer Footpath, solves the above problems, and will significantly facilitate dispenser and operates with.

Utility model content

The purpose of this utility model is to be improved dispenser position limiting convex ring shape and external diameter, beneficial to hand-held and fixed Medicine bottle, convenient operation.

To achieve these goals, the technical scheme that the utility model is taken is：

Existing dispenser displacement pin waist position limiting convex ring outer is widened, meanwhile, it is current in order to solve the matching of bulge loop external diameter The medicine bottle of two kinds of bottlenecks of market common size, ellipticity is fabricated to by bulge loop, and outer (6) width is 8-15mm, oval (or it is flat Circle) external diameter (20 ± 5mm) and the big bottleneck diameter of major axis approach, and external diameter (12 ± 2mm) and the small bottleneck diameter of ellipse short shaft connect Closely.

It is easy to the hand-held power of making in use, widening to increase with finger contact area due to bulge loop outer and is difficult to slip and pollutes Syringe needle, meanwhile, after displacement pin puncture enters medicine bottle stopper inside, bulge loop will be close to medicine bottle bottleneck, due to ellipticity bulge loop outer Major axis and short axle external diameter are approached with the diameter of vial size bottleneck respectively, can with finger easily while be affectedly bashful bulge loop and medicine Bottle, fixed medicine bottle and dispenser displacement pin are accurately made up a prescription.

Embodiment

Shown in Fig. 1 is the existing dispenser (patent No.：201220240075.3) schematic diagram, wherein position limiting convex ring (5) compared with It is small, and outer is flat.

Shown in Fig. 2 is the existing dispenser (patent No.：201220240075.3) position limiting convex ring operating diagram, dispenser Pin (2) insertion medicine bottle (b) and liquid bottles (B) are replaced, pass through position limiting convex ring (5) positioning action, it is ensured that displacement pin (2) medicine bottle end Perforate (3) is clean so as to which decoction is aspirated close at medicine bottle (b) bottle stopper.

Shown in Fig. 3 is the hand-held existing dispenser (patent No.：201220240075.3) operating diagram of position limiting convex ring, Because position limiting convex ring (5) is flat small, it is difficult to be affectedly bashful.

Shown in Fig. 4 is the utility model dispenser displacement pin schematic diagram, and position limiting convex ring (5) is widened at outer (6) place (thickness), be slightly narrower than into finger or wide；Oval (or oblate) shape, oval (or oblate) shape long shaft external diameter (20 are fabricated to simultaneously ± 5mm) approached with bottleneck (7) diameter of big medicine bottle (b)；Short axle external diameter (12 ± 2mm), bottleneck (7) diameter with phial (b) It is close.

Shown in Fig. 5 is hand-held the utility model dispenser position limiting convex ring schematic diagram, and position limiting convex ring (5) is at outer (6) place Widen (thickness), be easy to be affectedly bashful with finger and operated.

Shown in Fig. 6 is the utility model dispenser position limiting convex ring operating diagram, with consistent shown in Fig. 2, position limiting convex ring (5) positioning action is played, it is ensured that displacement pin (2) medicine bottle end perforate (3) is close at medicine bottle (b) bottle stopper.

Shown in Fig. 7 is hand-held the utility model dispenser position limiting convex ring and fixed medicine bottle operating diagram, due to spacing Bulge loop outer (6) external diameter and medicine bottle (b) bottleneck (7) diameter are approached, be affectedly bashful while can be easily with finger position limiting convex ring (5) and Accurately made up a prescription medicine bottle (b) bottleneck (7) place, fixed dispenser displacement pin (2) position.
