BODY FLUID SAMPLING DEVICE - SAMPLING SITE INTERFACE

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

DEVICES, SYSTEMS AND METHODS FOR GRAVITY-ENHANCED MICROFLUIDIC COLLECTION, HANDLING AND TRANSFERRING OF FLUIDS
20220039710 · 2022-02-10 ·

The disclosed apparatus, systems and methods relate to the collection of bodily fluids through the use of gravity and microfluidic properties by way of a collector. The collector can make use of microfluidic networks connected to collection sites on the skin of a subject to gather and shuttle blood into a reservoir by a combination of capillary action and gravitational forces. The collected fluid is moved through the microfluidic networks and into the reservoir by a variety of approaches.

Magazine for annulary capillary lancets

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.

Apparatus and methods for a lancet device for reuse of lancets for home-users
09757062 · 2017-09-12 ·

A lancet device used for drawing a blood sample for testing has a lancet, a lancet holding mechanism, a lancet activation plunger, and a removable lancet cap with an opening for touching against the human body. The lancet has a needle, where the needle is movable inside the cap with the lancet activation plunger. The lancet device has positioned inside the device, a disinfectant material, disinfecting the lancet needle for each use. The disinfectant material lets the needle move or rest inside the disinfectant material disinfecting the needle between each use. The lancet needle moves through the disinfectant material when used, disinfecting the needle for each use.

11395614 · 2022-07-26 · ·

Various collection devices, systems and methods relating to the use of devices with open microfluidic channels disposed within a housing defining a lumen. These devices make use of microneedles passed through apertures to induce fluid flow into microfluidic channel networks for collection and analysis. The device can be actuated via button when placed on the skin of a patient to collect a fluid sample, such as a blood draw.

FINGER NEEDLE PUNCTURE BLOOD COLLECTOR

The current invention concerns an integrated medical device for a self-collection test, which allows for both puncturing and collecting a blood sample.

Methods for collecting biological samples for quantifying heavy metals

Disclosed are devices, kits, compositions, and methods for collecting, transporting, and detecting toxicants, pathogens, and biomarkers in a biological sample. The devices, kits, compositions and methods may be utilized to collect and transport dried blood samples from a skin prick and detect toxicants, pathogens, and biomarkers in the dried blood samples.

Adjustable lancet and test cartridge for automated medical sample collection and testing
11202593 · 2021-12-21 · ·

A test cartridge includes an adjustable lancet. The adjustable lancet is controlled by a controller. The adjustable lancet automatically detects a subject's finger, adjusts the lancet's height, pricks the finger to draw blood, moves a tube to collect the blood, moves the tube away from the finger, and empties the blood from the tube into a vial or receptacle. The adjustable lancet may include safety features to prevent the lancet to trigger when the subject's fingernail is facing the lancet, to control the amount that the lancet pierces the subject's finger, and/or to prevent the reuse of a test cartridge for multiple persons or multiple times by the same person. The adjustable lancet may include a massager wheel and/or a pressure bar to rub the subject's finger after the finger is pierced to facilitate drawing of the blood from the finger.

BLOOD EXAMINATION KIT AND METHOD OF SEPARATING PLASMA OR SERUM

There are provided a blood examination kit with which the procedure carried out by an examination subject is simplified and a method of separating plasma or serum. The blood examination kit includes a blood collection instrument including a diluent and a first container that has an opening formed on one end side and accommodates the diluent; an absorption instrument including a first lid portion member that is arranged on one end side and can seal the opening of the first container, and an absorption member that is arranged on the other end side and absorbs a blood sample; and a separation and sealing instrument including a filtration member that separates plasma or serum from the blood sample diluted with the diluent, a second container that holds the filtration member on the other end side, accommodates the separated plasma or serum, and can be inserted into the first container, a second lid portion member that is arranged on one end side of the second container and can seal the opening of the first container, and a valve member that closes a flow channel between the first container and the second container.
