No. 61/711,179, filed on Oct. 8, 2012 of Tara Chand Singhal, for Apparatus and Method for an Integrated Medicine Vial and Injection Device for Individual Use. The contents of application No. 61/711,179 are incorporated herein by reference.
- This application is also related to and claims priority from application Ser. No. 12/807,481 filed on Sep. 7, 2010 of Tara Chand Singhal for Apparatus and methods for reuse of injection needle for home users.
- An integrated portable handheld fluid-medicine-injection device for home users is described. The device integrates a medicine vial, a dispense mechanism coupled with the vial, a needle with a needle mount/dismount mechanism coupled with the medicine vial and a needle storage mechanism that stores the needle when not in use and replenishes the needle for reuse.
- People across the United States and around the world suffer from a metabolic disease called diabetes. For many of these people who suffer from diabetes, taking insulin by injection is a requirement. There are two forms of insulin. One is longer acting insulin and is preferably injected once a day. The other type of insulin is faster acting insulin and is injected multiple times a day based on meal plans.
- Industry provides two different methods of injecting insulin; one is via a syringe and a bottle of insulin. The syringe is used to draw a required amount of insulin from the bottle and then used to inject. This method is mostly used for the slow acting insulin.
- The other method of injecting insulin is via what the industry calls an insulin pen, where a pen like device has a medicine vial coupled with an inject mechanism. Many different companies make such insulin pens. One example is Qwik® pen from Lily®.
- These insulin pens given their form-factor are considered and believed to be convenient to carry in a person's personal possession and used through out the day by users. The users of these insulin pens need to carry a separate supply of single use short needles. These needles are taken out of their storage container and mounted on the medicine vial of the insulin and these needles, once used, are removed from the vial and discarded.
- It is the objective of the embodiments herein to improve on the form-factor of the insulin pens and integrate the needle on the medicine vial without having to carry a separate supply and a container of single use needles. It is also the objective to reduce the number of steps a user would have to perform and also to reduce the overall size of such an integrated insulin pens to make it easier to carry and use such insulin pens.
- A portable handheld fluid-medicine-injection device for home users is described. Such a device is used for and useful for injecting insulin and may be used for and useful for injecting other fluid-medicines for home use.
- The device has a needle with a needle mount/dismount mechanism coupled with the medicine vial and a needle storage mechanism that stores the needle in a needle storage medium when the needle is not in use and replenishes the needle for reuse. The art of needle storage medium has been described in a prior application of the inventor, Ser. No. 12/807,481 filed on Sep. 7, 2010.
- The vial, the dispense mechanism, the needle, the needle mount/dismount mechanism and the needle storage mechanism are integrated into a single device that enables the use of the device for injecting medicine without a separate supply of single use injection needles.
- The vial, the dispense mechanism, the needle, the mount/dismount mechanism and the needle storage mechanism are integrated into a single device with the length profile and the thickness profile of the device to be carried in a clothing pocket.

FIG. 10 is a method diagram that illustrates features of a preferred embodiment of an integrated medicine-injection device for individual use. - With reference to
FIG. 1 , an integratedinsulin injection device 10 is described. No limitation is intended for the type of medicinal fluid that may be injected, even though insulin is the preferred medicinal fluid. - As illustrated in
FIG. 1 , thedevice 10 has threesub-assemblies - The
sub-assembly 10A is an inject sub-assembly and provides for aninject mechanism 24, adial mechanism 26 and a injectquantity display window 28. - The
sub-assembly 10B has amedicine vial 12 with avial mouth 12A and ainject push piston 12B, and aneedle engagement mechanism 16. - The sub-assembly 100 is a needle assembly and provides for an
injection needle 22, and aneedle storage medium 20 that is positioned inside aremovable needle cover 18. - The three
sub-assemblies device 10 are integrated into a single assembleddevice 10 making its easier to carry and use. Thedevice 10 would be carried in the personal possession of a user as injecting insulin is performed multiple times in a day that is tied to consumption of food and or blood glucose readings and may be required to be performed away from home and on the move. - Prior art may teach or suggest some aspects of
sub-assembly 10A andsub-assembly 10B. A prior pending application of the inventor Ser. No. 12/807,481 may teach or suggest sub-assembly 100. Therefore, what is believed are unique features of theinstant device 10 are summarized here. - The
device 10 has a length profile that is substantially 4.5″ in length and a thickness profile that is substantially ⅜″ thick and a width profile that is substantially ¾″ wide. These are notional dimensions and may be different than these dimensions without departing from the spirit and scope of the invention. - This profile makes it convenient to carry the
device 10 in pocket and personal possession of a user. In contrast, prior art insulin pen devices that generally have a length of 5½ inches and a diameter of ⅝″. - Prior art device has a medicine vial capacity of 300 units. The
device 10 also has a similar capacity and preferably has a capacity of around 200 units. - Like prior art device, medicine in
device 10 also requires refrigeration when the vial has not begun to be used to maintain the medicine potency during storage. It is believed, a medicine capacity of 200 units indevice 10 helps reduce the use period and it is believed may be better able to maintain potency during a use period of about two weeks. - Further the
device 10 in the sub-assembly 100 integrates a re-useable injection needle and a needle-mount and needle-dismount mechanism to and from the medicine vial as part of thedevice 10. This obviates the need or necessity to carry a separate supply of injection needles and manually mount and dismount such injection needles. The needle mount/dismount mechanism is integrated with the medicine vial. - Further this feature of re-useable injection needle also alleviates the issue of having to discard each needle after each use as in prior art insulin pen devices. Therefore, it is believed for these reasons the
device 10 would be preferred by the insulin pen users in contrast to the prior art insulin pens. - While the
sub-assembly 10C has been described as integrated with or useable with certain preferred versions or sizes ofsub-assembly sub-assembly - The
sub-assembly 10A and its mechanism are described with the help ofFIGS. 3, 4, 5A, and 5B . The sub-assembly 10B and its mechanisms are described with the help ofFIGS. 2 and 6 . The sub-assembly 100 and its mechanism are described with the help ofFIGS. 7, 8 and 9 .FIG. 10 provides a method diagram fordevice 10. - These and other aspects of the preferred embodiments of
device 10 are described in detail herein where the headings are provided for reader convenience. For ease in understanding the embodiments, details ofsub-assembly 10B are described first before the details ofsub-assembly 10A. -
FIG. 2 illustrates inview 40A, amedicine vial 12 that has avial mouth 12A and apush member 12B. Thepush member 12B is coupled with acylindrical tube 24 with internal threads. Arod 32 is positioned and screwed inside thetube 24 as has been illustrated later in the injectsub-assembly 10A. -
View 40B illustrates a cross section of the vial along X-X′. Thecross section 40B illustrates that the shape of the vial is rectangular with substantially ¾″ width and ⅜″ thickness. Like thevial 12 rest of thedevice 10parts 10A and 100 also have substantially the same profile in width and in thickness of thedevice 10. - This profile is preferred as opposed to prior art profiles of round shape medicine vials to reduce the thickness profile for making it easier to carry the
device 10 in a shirt pocket. -
View 40C shows thevial 12 when thepush member 12B has been pushed to a position inside thevial 12 to have used all the medicine in the vial. In this view thecylinder 24 has moved inside the vial when therod 32 has been unscrewed from thecylinder 24 and thus therod 32 remains outside thevial 12. -
View 39 shows some typical dimensions of the vial and its inside and outside dimensions with a view to illustrate a storage volume of this type of profile vial. With an inside vial size of 5 mm thick, 15 mm wide and 30 mm long the storage capacity of the vial is 2250 Cubic mm or 225 units, where a 1 ml has 100 units. These are notional dimensions and may be a little smaller or larger then these to provide a storage capacity of any where from 2 ml to 3 ml or 200 units to 300 units of medicine. Prior art storage capacity for insulin pens is 3 ml or 300 units. -
FIG. 6 illustrates aside view 42A of thevial 12. Thevial mouth 12A has arubber cap 38. The sides of thevial 12 havegroves needle engagement mechanism 16 as illustrated later with reference toFIGS. 7A and 7B .FIG. 6 also illustrates atop plan view 42B of thevial 12. Thevial mouth 12A may have grooves 17 for needle base engagement around the base of the outside of thevial mouth 12A. These grooves are intended to snap the needle base in position on thevial mouth 12A when pressed and then removed when pulled with a slight force. - The grooves 17 on the
vial mouth 12A may be in addition togrooves vial 12. Thegrooves medicine vial 12. The primary purpose ofgrooves 16 is to slide and guide the needle on to thevial mouth 12A. Both of these groove features 16A, 16B and 17 may be used to securely mount the needle onto thevial mouth 12A. -
FIG. 3 illustrates the features of inject mechanism ofsub-assembly 10A. Themedicine vial 12 has apush member 12B that is coupled with acylinder 24. Arod 32 is screwed inside thecylinder 24. Therod 32 is coupled with anothercylinder member 31. Thecylinder 31 has numerical markings on the surface and is coupled with atwist knob 29. - As shown in
FIG. 3 , thelength dimension 15A of the vial is notionally 1.75 inches including thevial mouth 12A. Thelength dimension 15B of the inject assembly is also notionally 1.75 inches. These two dimensions combined with the length of theneedle sub-assembly 10C provides for a notional dimension of 4.5 inch length of thedevice 10. -
FIG. 4 shows separate parts of the injection assembly viaviews casing 27 attached to thevial 12 covers the length of the inject mechanism and also provides for adisplay window 28 through which the marking related to the position of thecylinder 31, as shown inview 13C are visible. Thecasing cover 27 on one end is attached to thevial base 12 and on the other end has awindow 28. - With reference to view 13C, the
rod 32 hasexternal threads 33 that screw therod 32 inside thecylinder 24. The number and size of the threads are used to provide a gradation of one unit over 240 units of total movement of thecylinder 24, as inview 13A and thus to movement of thepush member 12B inside thevial 12. - As a simplified illustration, the number of threads may be 80 over one inch, where rotation of the
rod 32 by ⅓ of a rotation would provide for a graded movement over 240 units of thecylinder 24 and thus thepush member 12B to be able to inject medicine in increments of a single unit. - As in
view 13C, a spring loadedmechanism 35 lets theknob 29 be rotated freely to adjust and select a quantity of medicine to be injected, but when theknob 29 is pushed and the spring is engaged to dispense the medicine out of thevial 12, the knob is prevented from rotation. - The operation of the inject
mechanism 10A is illustrated with the help ofFIGS. 5A and 5B .View 13A shows the mechanism and the vial before any medicine has been drawn from the vial. - As illustrated in
view 13A, in the operation of the inject mechanism, therod 32 coupled with thecylinder 31 andknob 29 when turned anti-clockwise usingknob 29, unthreads the thread inside thecylinder 24 and as therod 32 is unthreaded theknob 29 moves out as illustrated inview 13B-1. A different part of thecylinder 31 with itscorresponding number 3 is visible through thedisplay window 28 signifying that the inject mechanism can push 3 units of the medicine in the vial. - As illustrated in
view 13B-2, when theknob 29 is pushed, thepush member 12B through thecylinder 24 moves up inside thevial 12 pushing the medicine out of thevial 12 via the needle when one is attached to thevial mouth 12B. When theknob 29 has been pushed down, the numbers on thecylinder 31 again display an initial value through thedisplay window 28. - When the
knob 29 is pushed, it is necessary that theknob 29 does not rotate. Therefore to stop the rotation of theknob 29 when theknob 29 is pushed, a spring loadedmechanism 35 may be used in theknob 29. The spring loadedmechanism 35 lets the knob be rotated freely to adjust and select a quantity of medicine to be injected, but when theknob 29 is pushed and the spring is engaged to dispense the medicine out of thevial 12, the knob is prevented from rotation. - A similar operation as had been illustrated with the help of
FIG. 5A is also illustrated with the help ofFIG. 5B .View 13B-2 has been copied here for reference.View 13C-1 shows that from the prior position as inview 13B-2, theknob 29 is unscrewed further out to display aunit 5 in thedisplay window 28. Inview 13C-2 as shown when theknob 29 is pushed all the way in, thecylinder 24 moves further inside the via 12 to inject 5 units of the medicine. Inview 13C-2, when theknob 29 has been pushed in, thedisplay window 28 again shows an initial value on thecylinder 31. - It is believed that this operation of the inject mechanism is similar in many aspects to what prior art teaches except the inject mechanism is coupled to and operative with the rectangular
profile medicine vial 12 and the injectmechanism casing 27 also has a rectangular profile to match the profile of themedicine vial 12. - Further, the
rod 32 with external threads being positioned insidecylinder 24 with internal threads reduce the length profile of the inject mechanism. ThusFIGS. 3, 4, 5A and 5B have illustrated theinjection sub-assembly 10A that is coupled with the medicine via 12 and thus integrated with themedicine vial sub-assembly 10B. - The needle assembly and mechanism 100 is illustrated with reference to
FIG. 7 ,FIG. 8 , andFIG. 9 . - With reference to
FIG. 7 , inview 14A, a prior art needle adapted to aneedle engagement mechanism 44 is shown. As illustrated inview 14A, theneedle engagement mechanism 44 preferably has anapron 49. Theapron 49 is in the form of a sheath or cover with a rectangular cross section. Theapron 49 slides up and down as theneedle engagement mechanism 44 is slid or moved up and down to mount and dismount the needle from themedicine vial mouth 12A. Theapron 49 thus covers the top part of themedicine vial 12 including hevial mouth 12A and theneedle base 46. -
View 14B illustrates different parts of theneedle engagement mechanism 44. As illustrated inview 14B, aprior art needle 22 has aneedle 22A and aneedle base 22B. - As illustrated in
view 14B, theengagement mechanism 44 hassupport members 46 holding theneedle base 22B. As illustrated inview 14C, thesesupport members 46 are positioned on top of thevial 12 around thevial mouth 12A. Themechanism 44 also hasengagement members 16. Thesupport members 46 are attached toengagement members 16. Themembers 16 slide over the sides of thevial 12 inside thegrooves - The
support members 46 also have a pair ofgroove mechanism members support members 46 and are used to attach to and hold aneedle storage mechanism 52. Theneedle storage mechanism 52 is illustrated later with the help ofFIG. 8 . - As shown in
view 14C, theneedle mechanism 44 is aligned on top of thevial 12 so that when the two are mated, thegrooves vial 12 can engage withengagement members 16 and at the same time theneedle 22base 22B can be mounted on to thevial mouth 12A. - As illustrated in
view 14B, amechanism 50 with balls on the ends of each of theengagement members 16 is seated in corresponding indentations ingrooves vial 12 as illustrated inview 14C. - As illustrated in
FIG. 8 , theneedle storage mechanism 52 has aneedle cover 18 and a needle-storage-medium 20 positioned inside theneedle cover 18. Theneedle storage medium 20 stores the needle in-between-use and disinfects, lubricates and sanitizes the needle for each reuse. Theneedle cover 18 hasvertical members grooves needle engagement mechanism 44 when theneedle cover 18 is pushed on theneedle support mechanism 46.FIG. 9 illustrates the operation of the needle assembly 100. - As illustrated in
FIG. 9 , inview 14A-1, thevial 12, theneedle engagement mechanism 44 and theneedle storage mechanism 52 are shown separately positioned on tip of each other in the order in which they are stacked. - In
view 14C-1, theneedle holding mechanism 44 has been engaged with theneedle storage mechanism 52 via thegrooves mechanisms vial 12 with the help ofengagement members 16. Theengagement members 16 slide into thegroves vial 12. As illustrated inview 14C-2, theneedle mount mechanism 44, and theneedle storage mechanism 52 are engaged with the medicine via 12. - In
view 14C-3, theneedle storage mechanism 52 has been pulled away or removed exposing theneedle 22 for use while theneedle base 22B is mounted on to thevial mouth 12A with theneedle engagement mechanism 44. - In operation these three individual mechanisms work together, starting with (i) view 14C-1 to store the needle inside the storage mechanism and not engaged with the
vial 12, (ii) view 14C-2, where the needle is engaged with thevial 12, and (iii) inview 14C-3, where theneedle storage cover 18 with theneedle storage medium 20 has been removed exposing the needle for injection. - A portable handheld fluid-medicine-injection device for home users, has an inject mechanism sub-assembly, a medicine vial sub-assembly, a needle mount and dismount sub-assembly for the medicine vial, and a needle storage assembly for a reusable injection needle. These sub-assemblies are integrated as one device, thereby making the device convenient to carry and use.

- A preferred mode of use of
device 10 is described here while other modes of use are not ruled out. When a need arises to inject insulin, based on glucose reading or at meal time, a user would retrievedevice 10 from their pocket or pocketbook. User would decide how many units to inject and would dial up thatquantity using knob 29 and see the quantity that has been dialed in thewindow 28. - The user would then grip the
apron 49 with thumb and forefinger and slide down theapron 49 to mount theneedle base 22B via theneedle engagement mechanism 44 on to themedicine vial mouth 12A. In this position theneedle base 22B is locked on to thevial mouth 12A with the help of grooves 17 around thevial mouth 12A. Themechanism 44 is also locked on to thevial 12 with the help of theengagement members 16 that move ingrooves indent mechanisms 50 incorporated therein. - The user then would remove the
needle cover 52 from theneedle engagement mechanism 44 to expose theneedle 22. The user would then insert theneedle 22 in the tissue and depressknob 29. After the injection process is completed, user would remove theneedle 22 from the tissue. - The user then would hold the
apron 49 and slide up theneedle engagement mechanism 44 to dismount theneedle base 22B from thevial mouth 12B. This would also unlock theindent mechanism 50 on thevial 12 and relock it on the top part of thevial 12. - The user then would mount the
needle cover mechanism 52 back on to theneedle 22 with the help of theguides mechanism 52 andgrooves needle engagement mechanism 44. - As soon as the
needle cover 52 is slid back over theneedle 22 with the help ofguides needle 22 with the help ofneedle storage medium 20 for the next use has begun. Then the user would put thedevice 10 back in the pocket until next use. - When the medicine in the
vial 12 is used up, thedevice 10 would be disposed of. It is assumed that given the quantity of medicine in thevial 12, thedevice 10 would last from a week to ten days, assuming 25 to 30 or so units are injected everyday. The device would last more or less than this time depending upon quantity of medicine needed by a given user. - Based on the number of days of ten the
device 10 would last, and the number of times thedevice 10 is used in a day, which is assumed to be three times, theneedle 22 of thedevice 10 would be reused approximately 30 times. Theneedle storage medium 20 is sized to be able to replenish theneedle 22 at least these number of times, as thedevice 10 is discarded after that many number of uses. - As illustrated in
FIG. 10 , method for using thedevice 10 has the following steps where all the steps may not be used or used in the order specified: - At step 100, having a medicine vial with a substantially rectangular cross section for reducing a thickness profile of the device and having a dispense mechanism coupled with the vial, the dispense mechanism having an inject push rod inside a threaded cylinder for reducing the length profile of the device.
