Devices and methods for withdrawing bodily fluid from a patient are disclosed herein. A handheld device configured in accordance with the present technology can include a housing having an opening, a skin-piercing assembly located at least partially within the housing, and an actuator movable relative to the housing along a deployment direction. The skin-piercing assembly can include a skin-piercing feature and a biasing member. The biasing member can be coupled to the skin-piercing feature to bias the skin-piercing feature along the deployment direction. Movement of the actuator along the deployment direction to a predetermined position can increase a load on the biasing member to at least a partially loaded state. Movement of the actuator along the deployment direction beyond the predetermined position can release the load on the biasing member so that the biasing member actively drives the skin-piercing feature along the deployment direction.

A method of assembling a lancet housing assembly comprising multiple lancets for use in a portable handheld medical diagnostic device for sampling bodily fluids from a skin site of a patient is disclosed. The method includes forming a plurality of lancet structures in a lancet sheet. The lancet sheet has a removable ledge for releasing the lancet structures. The removable ledge of the lancet sheet is flexed for releasing the lancet structures from the removable ledge.

The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. A deployment actuator may actuate the flow activator in a deployment direction, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, a device actuator may enable fluid communication between the opening and the vacuum source and the flow activator may be actuated after the enablement of fluid communication.

Devices are provided to automatically access blood from beneath or within skin. These devices include a plurality of injectors configured to drive needles into the skin and draw samples of blood into the device. These devices additionally include a plurality of sensors which can detect a target analyte in the blood samples received by the device. These devices further include a user interface, which may prompt the user to self-administer a dose of a substance, or accept a user input which could affect or otherwise influence the activation of the device (i.e., the firing of needles to draw blood samples into the device and detect an analyte). These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time after the user has self-administered a dose of a substance.

Provided is a blood collection apparatus with which blood can be stably collected from a finger tip of any subject while ensuring safety and ease. This blood collection apparatus is provided with: a puncture site holding mechanism for holding a puncture site; a compression mechanism for performing an operation of compressing and releasing the puncture site when blood is collected from the puncture site; a container holding mechanism for holding a container for collecting blood flowing from a puncture wound at the puncture site; and a driving mechanism for varying the relative distance between the puncture site and the container by vertically moving the puncture site holding mechanism, the container holding mechanism, or the container held by the container holding mechanism when blood flowing from the puncture wound is collected.

A safety needle device includes a housing including a passageway with a needle cannula extending therefrom. A shielding member is movable between a first position in which a puncture tip of the needle cannula is exposed therefrom and a second position in which the puncture tip of the needle cannula is encompassed therein. The shielding member is maintained in the first position against a biasing force which biases the shielding member toward the second position. A fluid and/or a temperature activation material is associated with the shielding member and is adapted to deform upon contact with a fluid medium and/or a certain temperature or temperature range. The fluid medium flowing through the needle cannula causes the fluid activation material to deform, such as through expansion, thereby releasing the shielding member from the first position and allowing a drive member to bias the shielding member toward the second position.

The present disclosure relates to a continuous blood glucose measurement device and an applicator, wherein the continuous blood glucose measurement device is produced in a state in which a body attachment unit has been assembled inside an applicator, so as to minimize a user's additional work of attaching the body attachment unit to the body, thereby enabling the body attachment unit to be attached to the body only by simply activating the applicator. Particularly, the present invention provides a continuous blood glucose measurement device and an applicator, wherein the continuous blood glucose measurement device: includes a wireless communication chip in a body attachment unit so as to enable communication with an external terminal, thereby enabling simple and convenient use thereof, without additional work for connecting a separate transmitter, and easier maintenance; and is activated by a user's operation after the body attachment unit is attached to the body, so as to enable the operation start time to be adjusted to an appropriate time according to user's needs, and to enable the operation to start in a stabilized state so that blood glucose can be measured more accurately.
