Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
A device for collecting, storage, transporting and discharging a liquid sample collected from a liquid supply desired to be examined for medical, industrial or diagnostic purposes comprising (a) a resilient absorbent member having sufficient capillary structure to absorb a portion of the liquid to be sampled when the absorbent member is placed in contact with the liquid supply or when the member is removed from the liquid supply to discharge the absorbed liquid upon the application of compressive pressure to the absorbent member; (b) a sealable container for receiving, containing, storage and transporting the absorbent member holding the liquid; (c) a handling stick for removably attaching the absorbent member thereto for inserting and removing the absorbent member relative to the liquid supply and the container respectively; (d) the handling stick is provided at one end with a fork portion having tines for holding the absorbent member.
Claim 2
Independent Claim
146 words
A device for collecting, storage, transporting and discharging a liquid sample collected from a liquid supply desired to be examined for medical, industrial or diagnostic purposes comprising (a) a resilient absorbent member having sufficient capillary structure to absorb a portion of the liquid to be sampled when the absorbent member is placed in contact with the liquid supply or when the member is removed from the liquid supply to discharge the absorbed liquid upon the application of compressive pressure to the absorbent member; (b) a sealable container for receiving, containing, storage and transporting the absorbent member holding the liquid; (c) a handling stick for removably attaching the absorbent member thereto for inserting and removing the absorbent member relative to the liquid supply and the container respectively; (d) the handling stick is provided at one end with a fork portion having tines for holding the absorbent member.
Claim 3
Dependent Claim
22 words
The device according to claim 1 wherein one of the tines is provided with a barb for releasably gripping the absorbent member.
Claim 4
Independent Claim
132 words
A device for collecting, storage, transporting and discharging a liquid sample collected from a liquid supply to be examined for medical, industrial or diagnostic purposes comprising (a) a resilient absorbent member having sufficient capillary structure to absorb a portion of the liquid to be sampled when the absorbent member is placed in contact with the liquid supply or when the member is removed from the liquid supply to discharge the absorbed liquid upon application of compressive pressure to the absorbent member; (b) a sealable container for receiving, containing, storage and transporting the absorbent member holding the liquid sample; and (c) an elongated handling member having a slotted end to receive and removably hold the absorbent member for collecting the liquid sample and depositing the absorbent member containing the sample into the container.
Claim 5
Independent Claim
132 words
A device for collecting, storage, transporting and discharging a liquid sample collected from a liquid supply to be examined for medical, industrial or diagnostic purposes comprising (a) a resilient absorbent member having sufficient capillary structure to absorb a portion of the liquid to be sampled when the absorbent member is placed in contact with the liquid supply or when the member is removed from the liquid supply to discharge the absorbed liquid upon application of compressive pressure to the absorbent member; (b) a sealable container for receiving, containing, storage and transporting the absorbent member holding the liquid sample; and (c) an elongated handling member having a slotted end to receive and removably hold the absorbent member for collecting the liquid sample and depositing the absorbent member containing the sample into the container.
