Systems and methods for autonomous intravenous needle insertion are disclosed herein. In an embodiment, a system for autonomous intravenous insertion include a robot arm, one or more sensors pivotally attached to the robot arm for gathering information about potential insertion sites in a subject arm, a medical device pivotally attached to the robot arm, and a controller in communication with the sensors and the robot arm, wherein the controller receives the information from the sensors about potential insertion sites, and the controller selects a target insertion site and directs the robot arm to insert the medical device into the target insertion site.

An applicator for applying a microneedle patch to a skin of a subject, comprising a base having a skin-side end and a holder for holding the microneedle patch. Two or more contact parts are movable over the skin and away from each other to stretch the skin. The applicator further comprising an interface for an actuator. The actuator actuates a movement of the microneedle patch relative to the skin-side end to penetrate at least into the stratum corneum of the epidermis of the skin with the microneedle. A microneedle patch comprising a skin-adhesive surface for attaching the patch to the skin of a subject. The patch has one or more projecting microneedles. A stiffening body stiffens the patch in at least a parallel direction parallel to the skin-adhesive surface in a region of the skin-adhesive surface which includes the microneedle.

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 venous access device includes a hub and a bifurcated cannula. The hub includes a bifurcated connecting arm, a blood sampling arm connected to the bifurcated connecting arm, a fluid transfer arm connected to the bifurcated connecting arm, a blood sampling channel and a fluid transfer channel. The blood sampling channel passes through the blood sampling arm and the bifurcated connecting arm. The fluid transfer channel passes through the fluid transfer arm and the bifurcated connecting arm. The bifurcated cannula is coupled to the bifurcated connecting arm and includes a blood sampling lumen having a blood sampling port, a fluid transfer lumen having a fluid transfer port, and a dividing member separating the blood sampling lumen from the fluid transfer lumen. The blood sampling port is 2 mm to 20 mm proximal from the fluid transfer port. The blood sampling channel is fluidly connected to the blood sampling lumen, and the fluid transfer channel is fluidly connected to the fluid transfer lumen.

A device for obtaining a biological sample, such as a capillary blood collection device, that has the ability to lance and squeeze the finger, collect the sample, stabilize the sample, and subsequently dispense the sample in a controlled manner is disclosed. The device also simplifies and streamlines the capillary blood collection by eliminating workflow variabilities which are typically associated with low sample quality including hemolysis and micro-clots.

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.

The presently disclosed subject matter is generally directed to a device that can be used as a tourniquet cuff for effective blood draws and IV insertion. The disclosed device assists skilled medical professionals in locating a vessel and inserting an intravenous tube, catheter, and/or blood drawing needle therein. Particularly, the device includes a cuff that wraps around at least a portion of a patient limb (e.g., an arm). The cuff is secured on the patient's limb with a plurality of straps that are tightened and secured about the circumference of the cuff. When the device is configured on the limb of a patient, the patient's blood vessels immediately engorge with blood. In this way, the vessels can be clearly visualized by or felt by a medical professional. As a result, blood can easily and efficiently be drawn and/or an IV successfully inserted without multiple attempts at finding the vessel.
