Description
2 0 ~ 7 ~ ~ ~3 This invention relates to a pill crushing and grinding means, adapted to convert solid pills and tablets of pharmacautical into powder form, for convenient dissol ution and subdivision of the unit dosage form.
It often happens in nursing home situations, where a substantial number of elderly patients are congregated, that a medication such as a tranquillizer must be distributed to and inge~ted by a substantial number ~f patients, relatively rapidly. For exampl~, this can h~ppen where emergency situations arisa in such a facility, requiring the evacuation of the patients in short order, but requiring that, in order that evacuation proceeds smoothly, a small amount of sedative or tranquillizer be ingested by each patient. The amounts required under such circumstances are commonly less than a Eull, standard pill or tablet of tranquillizer. In such cases, subdivision of the pills is required. This is best accomplished by reducing the pills to powder form, dissolving standard amounts of the powder form in a drink, and administering appropriate volumes of the drink to the patients, so that they receive the required subdivision of dose.
There are other situations in which the subdivi-sion of unit dosages of solid pills of pharmaceutical are desirable. For example, children are of~en required to be given less than a single unit dosage of pharmaceutical at a time, and the cutting of a pill into precise portions i5 impractical. Domestic pets and other domestic animals are commonly resistant to swallowing pills~ and are much more amenable to ingesting pharmaceuticals in powder form, wh~n mixed with other food or drink.
In a nursing home, on an average day, a nurse has to deal with at least ~ rounds of administra~ion o~ medica-tion. For those patients who tak~ individual medication there could be as many as ten pills per patient to be ~ ~ ç~
crushed ready for administration. The noise level assuci-ated with convention pill grinding using a mortar and pestle is generally high and objectionablQ to patients.
Standard issue pill crushers on the market ar~ inefficient when used with hard pills, and the nurse is often obliged to pound the pills in order to el-fect suitable breaking and crushing.
It is an object o~ the present invention to provide novel forms of pill crushers, which are simple and easy to operate, economical to construct, and well adapted for use in nursing home environments and in domestic environments.
According to the present invention, there is provided an apparatus for crushing or grinding pills or tablets, comprising:
tablet receiving and holding means;
rotar~ crushing or grinding means ha~ing a rotary shaft, a tabl~t contacting element on one end o~ the shaft and rotatable therewith;
means for rotating the rotary shaft;
said crushing or grinding means being mounted relative to the tablet receiving and holding means for movement between a tablet inserting position and a tablet contacting position.
In the preferred embodiments according to the invention, the means for rotating the rotary shaft is a manually operable handle. It has been found in practice that most efficie~t grinding and crushing of tahlets or pills is effected by a two stage operation. If mere compression is applied to a hard pill or tablet, some breakage occurs but essentially the resulting action is mer~ly one of compaction. I~ is mos~ desirable to ef~ec~t, firstly, a breaking of the tablet into smaller fractions, 2~72~
and then a crushing and yrinding operation applied to tha smaller fractions of tablets so producecl.
Suitably, according to the invention, the rotary shaft is screw th~eaded and is received in compliment~rily screw threaded receiver which is fixed with respect to the tablet receiving and holdi~g means. It is also preferred to allow for the rotary crushing or grinding means to havs a distance o~ free fall to implact on the tablet in the holding means, to provide for some breakage o~ the tablet on impact, followed by the rotary action o~ the crushing and grinding means, to reduce the table to powder, thereby introducing the aforementioned two staye action.
Larger scale versions of the apparatus according to the invention can be developed, which will grind an~
crush a plurality of pi.lls at the same time, either by manual rotation of the shaft containing a grinding element surface, or by power driven rotation of a shaft bearing one or more cut~ing blades which will act in cooperation with grinding surfaces of the pill or tablet receiving holding means to effect grinding of the tablet or pill into powder form.
Specifir preferred embodiments of the invention are illustrated in the accompanying drawings, in which:
: FIGURE 1 is a perspective view, with parts cut away, of a first embodiment of the present invention;
FIGURE 2 is a perspectiYe view of a second embodiment of the invention;

With ~eference to Fig. 1, the embodiment there illu~trated has a base 10 having a frustoconical recess 12 therein. Ups~anding ~rom the base 10 and straddling the recess 12 is an inverted U-shaped framework 14. The framework 14 is spriny mounted to the base 10 by springs 1~
mounted on screw threads 16 within the uprights of the framPwork. There is accordingly a small amount of "give"
between the framework 14 and the base 10. A screw threaded shaft 17 depends downwardly through the cross piece 18 o~
the framework 14 and carries on its lower end a tablet contacting element in the form of a frustoconical end piece 20. The shaft 17 and end piece 20 are manually rokatable by means o~ a handle 22 secured to the upper end of the shaft 17.
The shaft 17 passas vertically through a bore 24 in he cross piece 18. ~ lateral bore 26 extends horizon-tally through the cross piece 18. A spring loaded scr~w 28 extends along the lateral bore 26 and threadably cooperates with shaft 17 at their intersection, so that rotation o~
sha~t 17 by handle 22 causes ascent or descent of the sha~t 16 and end piece 20 relative to the framework. Screw 18 is provided with a recess 30 laterally offset from the inter-section with shaft 17. Screw 18 can, however, be moved laterally against i~s spring biasing to bring recess 30 into registry wi~h shaft 17, whereupon the threadable engagement is lost and the shaft 17 and end piece 20 can free fall into the recess 12.
~ liner in the ~orm of a volumetrically graduated cup 32, and a recessed holder 34 therefor, are also pro-vided. The cup 32 conveniently serves as the tablat holding means. It may be plac~d directly in recess 12, to which it is a close ~it, and a tablet contained therein crushed to powder by impact and rotation of end piece 20 thereon. Alternatively, cup 32 containing the tablet or pill may b~ placed in recess holder 34 and this placed under framework 1~ for impact and grinding of the tablet therein by the end p.iece 20.
In any ~vent, the operation of the device is, firstly, to withdraw screw 28 against its spring biasing so that recess 30 therein registers with the shaft 17, and then shaft 17 can be raised sufficiently to allow the placing of cup 32 containing a tablet with or without holder 34, into or over recess 12. The shaft I7 and end piece 20 are then allowed to free fall onto the tablet in th~ cup 32. This may in itsel:f cause the pill to break into smaller pieces. Then screw 28 is released so that it thrP,dably engages shaft 17. Manual rotation of shaft 17 will first work against the spring loaded "give" between the base and the framework 14, to complete the breaking of the tablet. Further ro~ation of the shaft will then complete the crushing and grinding of the tablet into powder, .in the cup 32. This two stage operation, o~ first breaking the pill and then crushing and grinding it, is particularly beneficial in producing the reguired fine powder. Appropriate dilu~e solutions of the crushed tablet can then be made up, after the actions are reversed and the cup 32 remov~d from the recess 12, using the gradations on the cup 32.
In the embodiment of Fig. 2, thP tablet or pill receiving and holding means comprises a recessed base 36, having screw threaded circular side walls 3~0 A rotary shaft 40, in one form, is provided as an elongated cylin-drical item, screw threaded to engage the side walls 3~ of the recessed base 3~. A handle 42 is pro~ided at the remote end of the shaf~ 40, for manual rotation thereGf.
In another fo~m, a platform 44 of similar size and shape to that of the recessed base 36 is provided at the remote end of the shaft ~0, to act as a handle. In ~oth cases, th2 table or pill to be crushed is disposed in the recess in base 36, and t'his is held by the operator in one hand. The .. . . . .
': .. . : ' ' ' '~ ' -.
shaft 40 is threadably enyaged onto the side walls 28 thereof and the handle rotated to crush the pill in the recessO These forms of the invention are particularly suitable ~or household, domestic use.
Figure 3 o~ the accompanying drawings show an embodiment of the invention in which the tablet receiving and holding means is a cup shaped ~lement ~ provlded within a larger, outer container 48. The rotary sha~t 50 o~ this embodiment carries a handle 52 at its top end, and projects downwardly through the cup element 46. The shaft has external grinding surfaces 54 which will cooperate with a side wall 56 of the cup element 58 to effect grinding to powder o~ a plurality of pills or tablets contained in the cup element 46. Rotary sha~t 50 is journalled in the bottom wall 60 o~ the cup element 46.
Figure 4 of the accompanying drawings illustrate~
a cutting element for use in replacement o~ the grinding element 50, 54 of the Fig. 3 embodiment, and for use of an electric motor for rotation purposes in~tead of a manually operable handle. The motor would be mounted in con~en~
tional fashion on the top wall 62 about a container 480 The rotary shaft 64 would engage the rotor of the electric motor, and the cuttiny blades 66, 68 would project into the cup element 46. By cooperation o~ the high speed rotating cutting blade 66, 6~ a~d the side walls 56 of the cup element 46, a substantial amount of tablets or pills contained in cup element 4~ can be rapidly chopped and ground to powder.
