Vacuum assisted lancing system with elective vacuum release and method for blood extraction with minimal pain
09770201 · 2017-09-26 ·

A vacuum assisted lancing system for blood extraction can include a tubular body having a vacuum chamber, a lancing mechanism configured to removably couple with a lance, a vacuum mechanism including a piston slideably coupled within the body, a release mechanism for selectively holding the vacuum mechanism in an energized state, and an opening for allowing fluid communication between the vacuum chamber and an atmosphere surrounding the vacuum chamber. The system can include structure for selectively commencing dissipation of the vacuum and a fixed or adjustable depth controller. A method of manipulating a surface for blood extraction can include coupling the lancing system to the surface, blocking the opening, creating a vacuum, moving the lance coupler from a first position distal from the surface to a second position proximal to the surface, maintaining the vacuum for a period of time, and commencing dissipation of the vacuum by unblocking the opening.

Adhesive and Peripheral Systems and Methods for Medical Devices

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

Single-handed operable infant heel blood sampling device and its safety mechanism
20250231090 · 2025-07-17 ·

The disclosure discloses a single-handed operable infant heel blood sampling device and its safety mechanism, including a push-pull rod and an actuating rod partially extending outside the blood sampler housing; the actuating rod has a second hook portion that can engage with the first hook portion; to perform blood sampling, push down the push-pull rod to disengage the buckle portion from the housing, causing the first hook portion to engage with the second hook portion on the first end of the actuating rod; then pull up the push-pull rod to pull the actuating rod, and the actuating rod thus releases a pre-compressed spring set inside the blood sampler housing, allowing the blade originally positioned in a first position inside the housing to slide out from a cutting port and then be retracted into a second position inside the housing.
