Abstract
A device for aspirating sample media into a pipette for use in a micro-manipulation procedure includes a ring member having an opening sized for receiving a digit of an operator, and an aspirating bulb engaged with the ring member. The aspirating bulb has an open end sized for receiving an end of the pipette, and includes a compressible chamber capable of creating a suction force suitable for aspirating the sample media into the pipette. The aspirating bulb is oriented along the ring member such that the chamber is compressible by a digit on the same hand of the operator as the digit receivable in the ring member.
Claims20
A device for use in aspirating sample media into a pipette, comprising:
- a ring member, said ring member having an opening sized for receiving at least one of a digit of an operator and a substrate capable of being grasped by a hand of the operator;
- and
- an aspirating bulb engaged with the ring member, said aspirating bulb having an open end sized for receiving an end of the pipette therein, and having a closed end, said aspirating bulb including a compressible chamber capable of creating a suction force suitable for aspirating said sample media into said pipette, said aspirating bulb being oriented along said ring member such that said chamber is compressible by a digit on the same hand of the operator as the digit receivable in the ring member or on the hand that grasps the substrate.
A method for aspirating sample media from a reservoir into a pipette for carrying out a micro-manipulation procedure, comprising:
- providing an aspirating device comprising a ring member and a bulb, said ring member having an opening sized for receiving a finger of an operator or a substrate capable of being grasped by the operator, said bulb engaged with a surface of the ring member, said bulb having an open end sized for receiving an end of the pipette therein, said bulb including a compressible chamber for creating an aspirating force;
- introducing said finger or said substrate through said ring member opening;
- inserting a first end of said pipette into said bulb open end;
- compressing said chamber for creating said aspirating force;
- inserting a second end of said pipette into said reservoir of sample media;
- and
- at least partially releasing said compression and aspirating at least a portion of said sample media into said pipette.
A system for use in carrying out a micro-manipulation procedure, the system comprising:
- a pipette sized for receiving a sample media for use in said micro-manipulation procedure;
- and
- a device for aspirating said sample media into said pipette, said device comprising a ring member and a bulb engaged with a surface of the ring member, said ring member having an opening sized for receiving at least one of a digit of an operator and a substrate capable of being grasped by an operator carrying out the procedure, said bulb having an open end sized for receiving an end of said pipette therein, said bulb including a compressible chamber capable of creating a suction force suitable for aspirating said sample media.
