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 container at least to some extent composed of a sheet of composite material, where the composite material includes an aluminum foil with a first and a second surface side, a first polymer layer, bonded to at least one of the two surface sides, where the aluminum foil covers, by way of the polymer layer, at least one aperture of a holder, where the composite material and the holder together form the container, where the holder accepts at least one analytical aid in a cutout, where the aluminum foil has been molded.

A device for receiving a body fluid for analysis, comprising a container and at least one sample-receiving unit which can be impinged upon by the body fluid at a receiving point and which can be extracted from a guide chamber of the container by means of a drive unit. According to the invention, a coupling device is provided in order to couple the sample receiving unit to the drive unit to ensure back and forth movement between the guide chamber and the receiving point.

Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.

A disposable lancing device contains: a first casing, a second casing, and a needle holder. The first casing includes a close segment, an open segment, a slideway, two tilted contact faces, a fixing portion, two recesses, and two push fringes. The second casing includes an accommodation chamber, two limitation extensions, and multiple drive protrusions. A forcing face is defined on the second casing opposite to the two limitation extensions, and a through hole is defined on a center of the forcing face. The through hole has a protruded rib. The needle holder includes a collection needle having a syringe needle, and the needle holder further includes a trigger spring, a return spring, and two symmetrical flexible wings. The two symmetrical flexible wings include two driving segments configured to abut against the two symmetrical flexible wings to flexibly retract inward by using the two tilted contact faces.

A one step all-in-one apparatus for body fluid sampling and sensing, comprising: a housing(1), a plurality of integrated sampling and sensing assemblies, a cartridge(12), sealing films(101,102), an upper cover(13), a sampling port(6), a linear actuating mechanism and a control circuit, with every integrated sampling and sensing assembly comprising a micro fluid-sampling needle(2), a needle hub(3) and a test strip(4); the micro fluid-sampling needles(2) penetrate the skin to sample the body fluid and deliver the body fluid to the test strips(4) directly, and changes occurred on the test strips(4) are read by the sensor(5), wherein sampling and sensing are completed in one step. The sealing films(101,102) and a plurality of chambers(15) of the cartridge(12) compose sealed reaction chambers(15) and the linear actuating mechanism which is connected with the control circuit electrically drives the integrated sampling and sensing assemblies allowing the micro sampling needles(2) to penetrate the skin and reach the designated depths under the skin. The one step all-in-one apparatus for body fluid sampling and sensing has advantages as small size, high efficiency, convenient operation, short time consumption, less fluid consumption, depth-controllable penetration, and accurate and reliable results.

The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.
