Abstract

A suction tube for use with a medication dispensing system is provided, comprising a handle which houses a suction motor powered by an external power source; a stationary tube attached to and extending from the handle in fluid communication with the suction motor; a screen to prevent the passage of pills into the suction motor; a second tube slidably attached to the stationary tube, the second tube having a distal end; a pill obstructor on the second tube for preventing a retrieved pill from traveling through the second tube; collection cup retainer attached to the handle for holding a collection cup; a pill guide positioned adjacent to the collection cup retainer for guiding the retrieved pill to the collection cup; and a sensor located within the pill guide for detecting the passage of the retrieved pill through the suction tube. Preferably, the suction tube includes an adjustable pill exit aperture which can also be used to adjust the suction strength through the suction tube. Optionally, the suction tube may also include an attachment which allows for adjustment of the pill inlet as well.

Claims

1. A suction tube for use with a medication dispensing system, comprising:

(a) a handle which houses a suction motor powered by an external power source;

(b) a stationary tube attached to and extending from said handle in fluid communication with said suction motor;

(c) a second tube slidably attached to said stationary tube, said second tube having a distal end;

(d) pill obstruction means on said second tube for preventing a retrieved pill from traveling through said second tube;

(e) collection cup retaining means attached to said handle for holding a collection cup;

(f) pill guiding means positioned adjacent to said collection cup retaining means for guiding said retrieved pill to said collection cup; and

(g) sensing means operatively disposed within said pill guiding means for detecting the passage of said retrieved pill through said pill guiding means.

2. The suction tube of claim 1, wherein said stationary tube includes an adjustable pill exit aperture alignable with said collection cup.

3. The suction tube of claim 1, wherein said stationary tube includes means for adjusting the airflow through said stationary tube created by said suction motor.

4. The suction tube of claim 1, wherein said pill obstruction means comprises a lever having a lower portion which extends into the distal end of said second tube, and wherein said lower portion is resiliently biased into said second tube.

5. The suction tube of claim 1, wherein said pill obstruction means comprises a screen attached within the distal end of said second tube.

6. The suction tube of claim 1, wherein said pill obstruction means comprises a sleeve slidably attached to the distal end of said second tube, wherein said sleeve includes an adjustable pill inlet.

7. The suction tube of claim 1, further including a screen within said stationary tube to prevent said retrieved pill from entering said suction motor.

8. The suction tube of claim 1, wherein said second tube is telescopingly slidable within said stationary tube, and said stationary tube further includes locking means operatively disposed between said stationary tube and said second tube for selectively locking the position of said second tube in either a retracted position or an extended position relative to said stationary tube.

9. The suction tube of claim 8, wherein:

(a) said pill guiding means comprises a guide tube mounted exterior to said stationary tube, and wherein a pill exit port is formed into said stationary tube leading into said guide tube; and

(b) said distal end of said second tube is aligned with said pill exit port when said second tube is maintained in said retracted position.

10. The suction tube of claim 8, wherein said second tube is resiliently biased toward said extended position.

11. The suction tube of claim 1, wherein said sensing means comprises an infrared sensor having an emitter and a detector, and wherein the passage of said retrieved pill through said pill guiding means is detected upon obstruction of the energy from said emitter to said detector by said retrieved pill.
