Vacuum assisted lancing system with system and method for blood extraction and masking pain
First Claim
1. A method of masking pain resulting from a lancing system for blood extraction, the system comprising a tubular body having a longitudinal axis, a lancing end and a longitudinally opposite free end, and a lancing assembly coupled to the body, the lancing assembly having a lance coupler with a lance coupled thereto for penetrating a surface from which the blood is to be extracted, the method comprising:
- simultaneously moving a first portion and a second portion of the lancing assembly in a first direction along the longitudinal axis toward the free end;
contacting a component of the lancing assembly with the first portion, thereby stopping the first portion of the lancing assembly from further moving in the first direction and causing a first vibration;
thereafter moving the first portion in a second direction opposite the first direction while the second portion continues moving in the first direction, the second direction being along the longitudinal axis toward the lancing end; and
lancing the surface with the first portion while the first vibration is occurring.

Abstract
A method of masking pain resulting from a lancing system can include moving a first portion and a second portion of a lancing assembly in a first direction, stopping the first portion from further moving in the first direction, thereby causing a first vibration, allowing the first portion to move in a second direction while the second portion continues moving in the first direction, and lancing a surface with the first portion while the first vibration is occurring. A system for lancing a surface and masking resulting pain may include a device body having an end adapted to sealingly engage the surface, structure for creating a first portion of a vacuum, structure for causing a vibration, and a lancing mechanism adapted to lance the surface while the first portion of the vacuum and the vibration are acting on the surface.

11. A method of masking pain resulting from a lancing system for blood extraction, the system comprising a tubular body having a longitudinal axis, a lancing end and a free end, the lancing end having a sealing device coupled thereto, a lancing shaft having a lance coupling end and an actuating end, a lance coupled to the lance coupling end of the lancing shaft, a release mechanism coupled to the body, a main shaft having an actuating end, a free end and a release coupler there between, wherein the main shaft is slideably coupled with the body so that the release coupler may communicate with the release mechanism, and wherein the actuating end of the main shaft is disposed inside the body toward the actuating end of the lancing shaft, a piston coupled to the main shaft and disposed within the body so that a vacuum chamber is formed between the sealing device and the piston, an opening that allows fluid communication between the vacuum chamber and an atmosphere surrounding the vacuum chamber, a vacuum spring coupled within the body so that the piston is biased toward the free end of the body and away from the actuating end of the lancing shaft, and a shaft coupler having at least two separable portions, wherein a first portion is coupled to the actuating end of the lancing shaft and a second portion is coupled to the actuating end of the main shaft, the method comprising:
-
cocking the lancing system by moving the actuating end of the main shaft, energizing the vacuum spring, coupling the at least two separable portions of the shaft coupler together and coupling the release coupler to the release mechanism; coupling the sealing device to a surface for blood extraction and forming at least a partial seal between the sealing device and the surface; uncoupling the release coupler from the release mechanism; allowing the vacuum spring to at least partially deenergize, thereby moving the at least two separable portions of the shaft coupler in a first direction along the longitudinal axis toward the free end of the body; contacting a component of the system with the first portion, thereby stopping the first portion of the shaft coupler from further moving in the first direction and causing a first vibration; uncoupling the at least two separable portions of the shaft coupler to allow the at least two separable portions to move independently from one another within the body; allowing the piston to travel in the first direction; creating a vacuum between the surface and the piston thereby subjecting the surface to the vacuum; thereafter moving the first portion of the shaft coupler in a second direction opposite the first direction while the second portion of the shaft coupler continues moving in the first direction, the second direction being along the longitudinal axis toward the lancing end of the body; and lancing the surface while the surface is subjected to the vacuum and while the first vibration is occurring. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
