Abstract

An injector wherein a stopper which runs against the rear end surface of a cylinder to limit the forward movement of a piston is mounted movably in the axial direction on the outer periphery of said piston; the max. scale of the cylinder being marked at a position which coincides with that of the front end surface of said piston when said piston has been moved to a point where said stopper runs against the rear end surface of the cylinder, with an engaging part of the stopper locked at the forefront of the engaging part provided on said piston to lock the stopper. And, each of all the spaces between each two of the engaging parts provided on the piston to lock the stopper can be made identical with each of all the spaces between each two of the scale marks notched on the cylinder.

Description

SPECIFICATION Injection device The present invention relates to an injection device forinjecting afluid,and more particularlytoan improved injector which may be employed in any work in which an injection operation is required, for example, such as a hypodermic syringe for use in medicine.
In a conventional injector, a scale is provided on the barrel or the plunger to enable a user to measure the required amount of a liquid by reading the scale.
However, conventional injectors have the disadvan tagethatthe user has to look at the scale each time of use. Furthermore, it is hard to stop the plunger at the desired position ofthe scale ofthe injector correctly, so that an error in the amount of injected fluid is often produced.
In orderto overcome these drawbacks, hitherto many adjustable injection devices have been proposed. For example, it has been proposed to provide a stopper means on the plungerofan injector, so that a desired amount of liquid is injected by moving the plunger until the stopper means abuts the upper end of the barrel ofthe injector. However, although such an injection device allows the injection of the desired amount of liquid accurately and simply, the device cannot be very easily set-up, especiallywhen it is desired to inject the same quantity of liquid on several occasions. In pa rticular, the hitherto proposed device requires a scale to be read on the plunger or the barrel when liquid is introduced into the device.No injection device has previously been proposed for introducing the liquidaccuratelyorsimplywithoutreadingascale.
It is troublesome for a user, particularly a blind user, to have to read the scale of an injection device each time the amount of liquid hasto be confirmed.
We have nowfound it possible to provide an injection device which may be used to accurately inject a specific amount of liquid withoutthe necessity to read a scale.
According to the present invention there is provided an injector having stopper means for preventing a plungerofthe injectorfrom being advanced beyond a predetermined position wherein the stopper means is mounted on an outer peripheral portion ofthe plunger so astro be movable in a longitudinal direction of said plunger; a projection is provided on the stopper rneanswhich may be disconnectably engaged with one or more connecting grooves on the plunger; a maximum graduation scale point being situated on the barrel sothatwhenthefrontface ofthe plunger is in a position corresponding to this point, the front face of the stopper means abuts the rear end surface of the barrel.
In the injector according to the invention, a plurality of graduation points are preferably provided, conveniently on a scale marked on the side of the barrel, and a plurality of connecting grooves are provided on the plunger with the distance between adjacent grooves corresponding to the distance between adjacent graduations on the scale.
An embodiment ofthe present invention is hereinaf- ter particularly described by way ofnon-limiting example and with reference to the accompanying drawings, in which: Figure 1 shows a partial longituindal sectional front view of an injector according to the invention filled to the maximum scale value; Figure 2 shows a longitudinalfrontviewofthe injector of Figure 1 filled with a specific amount of liquid which correspondsto avolumeonegraduation less than the full scale reading and which corresponds to a position ofthe stopper where a projection thereof engages a contacting groove one back from the most forward groove; Figure 3 shows the injector of Figure 1 before introducing a liquid into the barrel; and Figure4showsthe injectorof Figure 1 when liquid is introduced overthe maximum scale.
Referring to the drawings, injector 1 comprises a plunger 2, a stopper3 and a barrel 4. The plunger2 is provided with a seal portion 2a ata top end thereof, which intimately contacts the inner surface of the barrel 4 and can freely move along the axis of the barrel. At a rear end ofthe plunger 2, a stem portion 2b is provided which had contacting grooves 5 spaced apart from each other at predetermined intervals. A longitudinal g roove 6 is provided on the stem portion 2b. At the rear most end ofthe plunger 2, a flange 2c is provided in order to assist injection.
The stopper 3 has a cylindrical part 3a, the outer diameter of which is largerthan inner diameter of the barrel 4.-A projection 3b on the inner edge ofthe opening top end of the stopper 3 is provided which can engage with contacting grooves Son the stem part 2b ofthe plunger. Aflange 3c atthe rear end of the cylindrical part 3a is provided. The stopper 3 is mounted on the outer peripheral surface of the stem part 2b of the plunger 2 and movable axially and rotatably on the circumference of the plunger 2.
Movementofthe stopper 3 can be effected by rotating the plunger 2 or stopper 3 in a circumferential direction so that the projection 3b of the stopper 3 takes a position in the longitudinal groove 6, and then moving the stopper freely along the longitudinal groove 6.
In some embodiments, e.g. where no longitudinal groove 6 is provided, the projection 3b may be formed of a plastic material which is resiliently deformable.
When the stopper 3 islongitudinally moved relative to the barrel the projection 3b periodically engages and disengages with each contacting groove 5 and may produce a clicking noise. Consequently, such a noise enables the user, particularly a blind user, to know to what extent the stopper 3 has been moved without necessarily looking at any scale which may or may not be provided on the barrel 4.
Thebarrel4comprisesacylindricalpart4a,which may contain a liquid 8; a needle part4b atthe end of the cylindrical part4a,andaflangepart4cwhich may contact a front face ofthe stopper 3. On the outer surface ofthe cylindrical part4a a scale 7 is conveniently provided with intervals corresponding to the distance between the contacting grooves 5.
On the scale 7, the maximum scale point7a corresponds with the position of the front end face of the seal portion 2a when the plunger 3 is moved downward until the front face of the stopper abuts the barrel flange part4c, provided that the projection 3b of the stopper3 engages with the most forward position of the contacting groove 5a (see Figure 1).
In operation ofthe injector it may be preferred if a different clicking feeling or noise is produced when the projection 3b ofthe stopper3 contacts a specific point in the row of contacting grooves 5, or if a remarkably distinctive marking is provided.
The operation ofthe injection device shown in the drawings will be described in detail below.
First, as shown in Figure 3, thefrontface of the seal portion 2a is contacted with the bottom of the barrel 4 by moving the plunger 2 downwardly, provided that the stopper 3 is kept atthe upper end ofthe plunger 2 until the stopper flange 3c approaches the plunger flange part2c.
Injection liquid 8 is fully introduced into the barrel 4 when the plunger 2 is partially withdrawn from the barrel 4 as long as the'rear end ofthe seal 2a is drawn back overthe maximum graduation 7a. Subsequently, the projection 3b of the stopper 3 is moved and positioned on the plunger stem part 2b so thatthe interval between the rear end surface of the barrel 4 and the front end face of the stopper 3 is adjusted according to the desired amount of liquid for injection.
Figure 4 shows the injector with the maximum amount of liquid introduced into the barrel 4 and the projection 3b is fixedly positioned atthe upper most partofthecontacting grooves 5.
If it is not desired to inject the maximum amount of liquid 8, the projection 3b of the stopper 3 may be ,positioned at the n-th position corresponding to the n-th graduation ofthe scale, as desired.
Thus, the plunger 2 can be simply advanced in the barrel 4 until the frontface of the stopper3 abuts the rear end ofthecylinderflange part4cthereby ensuring thatthe desired amount of liquid is held in the barrel 4. If the user wishes to fill the maximum quantity of liquid,the plunger 2 is advanced until the frontface ofthe seal portion 2a takes a position corresponding to maximum graduation 7a, as shown in Figure 1.
Alternatively, if the user wishes to fill the injector with liquid in an amount corresponding to the n-th graduation of the scale, the plunger 2 may be advanced until the face of the plunger flange 2c abuts the frontface ofthe stopperflange3c,which is positioned by setting the projection 3b in the n-th groove. in this way, the seal portion 2a may be correctly advanced to a position corresponding to the n-th graduation. The filling of liquid is thus completed.
After filling the liquid, the liquid may be injected by advancing the plunger after releasing and moving the stopper backward from the setting position to the underface of the plungerflange 2c.
The liquid may also be injected in an amount corresponding to each graduation with uniformity. In this case, the stopper may be operated as a stopper for injecting the liquid, not onlyforfiling the liquid.
The injector ofthe present invention enables the userto easily and correctly inject a prescribed amount of liquidwithoutthe need to confirm an amount by looking at a scale on the plunger or barrel.
As explained above, the injector may further be preferablefora blind user if movement of the stopper produces a clicking noise when the stopper 3 is longitudinally moved relative to the plunger 2.
