20170274155 · 2017-09-28 ·

A device for giving injections has a housing having a lower surface and an upper surface with a passage through the housing extending between the upper and lower surfaces. A DC motor with an eccentric fixed to the motor is boated inside the housing to vibrate the housing. At least one tubular insert is located in the passage through the housing and is fixed to the housing. A syringe receiver is located inside and fixed to the at least one tubular insert. The syringe receiver contains a foam insert defining a space for receiving a syringe. The foam insert is a polyurethane foam characterized by an indentation force deflection of about 25% at 127 N and about 65% at 256 N. The foam insert isolates a syringe from the vibrating of the housing.

A device (1) for obtaining a biological sample that includes a blood collection device (10) and a vibration device (80) removably attachable to the blood collection device that provides pain relief is disclosed. The vibration device of the present disclosure provides pain relief to a patient by vibrating the blood collection device. The vibration device can be attached to the blood collection device before it is placed onto a finger to provide pain relief during the finger lancing as well as to aid blood flow from the finger into a collection container during the collection process.

BLOOD SAMPLING DEVICE AND METHOD OF USING THE SAME
20250235135 · 2025-07-24 ·

The present disclosure provides a lancing device that includes a lancet for piercing a user's skin and a lancing device body to drive the lancet. An actuator included in the lancing device body can drive the lancet to perform a linear reciprocating motion multiple times upon a single activation. Accordingly, the lancet may pierce the user's skin multiple times upon a single activation.

Lancing device with ejector

A lancing device with an ejector that is movably retained with a housing in proximity to a lancet and is selectively movable between a home position, a first eject position, an intermediate position defined by contact of the ejector with the lancet, and a second eject position. The ejector is rotatable to move from the home to first eject position and is linearly translatable to move between the first and second eject positions. The ejector includes an arm that extends within the housing and engages the lancet, an exterior portion that is actuated by a user, and a post extending therebetween. The post extends through a slot in the housing which limits the linear movement and direction of the ejector. Upon rotation of the ejector, the arm extends through an opening at the rear of the carriage holding the lancet to permit access to the lancet.
