This disclosure relates to a system and method for drawing blood from a user by skin puncture instead of venous puncture and storing it for analysis. The system includes a receptacle configured to engage an area of skin of the user at a blood draw location and store blood drawn from the user; a lancet device disposed within the receptacle configured to puncture the skin of the user at the blood draw location; a vacuum device configured to reduce a pressure within the receptacle such that the skin at the blood draw location is drawn into the receptacle before the lancet device punctures the skin, and to enhance blood flow while blood is drawn from the user; and a housing configured to house the receptacle, the lancet device, and the vacuum device. The receptacle, the lancet device, and the vacuum device may be modular and removably coupled with the housing.

A segmented safety cover may include a proximal segment combined with a needle hub; a needle cannula that extends from the proximal needle hub to a distal sharpened end; a distal end cap with a hollow bore through which the needle cannula passes; a centrally mounted toggle locking mechanism, separating the proximal needle hub from the distal end cap; the toggle locking mechanism is torsion spring assisted; a proximal cover segment is connected to the hub via a proximal hinge and a distal cover segment is connected to the end cap via a distal hinge; said proximal cover segment and said distal cover segment of said toggle locking mechanism being configured with abutting faces when the segmented safety cover is in a safety mode; and wherein the proximal hinge, abutting faces and distal hinge are in line in the safe mode.

Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. 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 while a wearer of a device is sleeping.

A device for shielding at least part of a limb from the view of a wearer of the device. The shielding device may include a shield with a first configuration in which it is substantially planar and a second configuration in which it has a three-dimensional shape. The shield may include one or more hinge lines, enabling it to be converted from the first configuration to the second configuration. The device also may include an attachment portion with one or more elongate members to attach around a limb of a wearer in use. An edge portion of the shield may include an outer edge opposite the hinge line that is at least partially divided into independently moveable sections such that the edge portion can be flexed to help convert the shield into a three-dimensional configuration.

Provided is a non-invasive blood measuring device comprising: a fixture which in part or in whole is buried in bone tissue of a patient; an abutment provided in a space inside the fixture; a sensing unit including biosensors for measuring a substance in the blood; a filter through which the substance in the blood to be measured is passed through; and an outcall unit.
