摘要:
A motorized sample collection apparatus having a hollow clamshell casing with a contoured grip for the fingers, a horizontal extension to eliminate slippage when held in a user's hand, and a flange bottom portion from which a sample sleeve extends downwards. Within the clamshell casing an electric motor is mounted which drives, via spur gears the sample sleeve in a rotational manner. The distal end of the sample sleeve, is a cutting edge circumscribing a circular region. An ejection rod slides reciprocally within the sample sleeve between a retracted stowed position and an expulsion position. User cuts a sample from a substrate by engaging contact between the cutting edge of the sample sleeve and the substrate, applying pressure against the substrate and activating the motor to rotate the sample sleeve. Activation of the ejection rod towards the expulsion position displaces the sample into an appropriate collecting vessel.

A motorized apparatus to simultaneously excise, retrieve, temporarily store and transport a sample of material has a hollow clamshell casing with a blended contoured grip for the fingers, a horizontal extension to eliminate slippage when held in a user's hand, and a flange bottom portion from which a removable cutting tool threaded to a drive shaft extends downwards. Within the clamshell casing an electric motor is mounted which drives, via gears, a drive shaft which rotates a cutting tool threaded to the distal end of the drive shaft. The end of the cutting tool, distal from the clamshell casing, forms a cutting edge circumscribing a circular region. An ejection rod slides reciprocally within the cutting tool between a stowed position and an expulsion position. Users core a sample from the source material by engaging contact between the cutting edge of the cutting tool and the surface of the source material, applying pressure against the surface of the source material while simultaneously activating the motor to rotate the cutting tool. The cutting region of the cutting tool passes through the source material contacting the support surface below the source material which urges the cored sample into the lumen of the cutting tool. The sample may be stored in the lumen or transported. Activation of the ejection rod moves from the stowed position towards the expulsion position displacing the temporarily stored sample from the lumen space in the cutting tool into the appropriate collection receptacle or onto a desired surface.

An apparatus to collect a sample of material has a handle with a tubular sample sleeve extending from an end of the handle. The end of the sleeve distal from the handle forms a cutting edge circumscribing a circular sampling region. A plunger slides reciprocally within the tubular sample sleeve between a retracted position and an expulsion position. A user cuts a sample from a source material by engaging contact between the cutting edge of the tubular sample sleeve and the source material. The sample cut from the source is lodged within the tubular sample sleeve. Actuation of the plunger from the retracted position toward the expulsion position displacing the sample from the sleeve.
