Принадлежит: Facet Technologies LLC

A lancing device and a cartridge of lancets are operable to sequentially advance each lancet to an active position for use in sampling a bodily fluid. An alignment mechanism precisely aligns the lancets in the active position to promote smooth operation and prevent jamming. The alignment mechanism includes at least one register element and at least one spring-biased element movable between engaged and retracted positions. In an example embodiment, one spring-biased arm extends from the lancing-device housing and includes a protrusion, and a series of recessed register surfaces are defined in a carrier for the lancets. In the engaged position, the spring-biased protrusion fully mates with the register recess under the spring-biasing influence to precisely align the active lancet. And in the retracted position, the spring-biased protrusion is deflected from engagement with the register recess as the carrier is advanced to advance a fresh lancet into the active position.

Systems and methods for delivering to and/or receiving fluids or other materials, such as blood or interstitial fluid, from subjects, e.g., from the skin. Beading disruptors and/or capillaries may be used for facilitating the transport of fluids from a subject into a device. Beading disruptors may disrupt the “pooling” of bodily fluids such as blood on the surface of the skin and help influence flow in a desired way. A capillary may conduct flow of fluid in the device, e.g., to an inlet of a channel or other flow path that leads to a storage chamber. A vacuum (reduced pressure relative to ambient) may be used to receive fluid into the device, e.g., by using relatively low pressure to draw fluid into the inlet of a channel leading to a storage chamber. The vacuum source may be part of the device.

Providing an ID-verified blood test, in one aspect, may include enabling a user to press a finger against a fingerprint-reading panel and reading a fingerprint of the user. A blood sampling device coupled to the fingerprint-reading panel may be activated while the user has the finger against the fingerprint-reading panel to sample blood from the finger. Blood may be sampled from the user via the blood sampling device while the user has the finger against the fingerprint-reading panel. A test may be performed on the sampled blood to determine a level of specified chemical in the blood. User identification may be determined based on the fingerprint. The determined user identification and the level of the specified chemical may be returned.

An improved safe and convenient disposable automatic lancet, comprising a housing ( 1 ), a needle core ( 2 ), a spring ( 3 ) and a protective rod ( 4 ), wherein, a pressing arm of a trigger button ( 10 ) is divided into a first pressing leg ( 11 ) and a second pressing leg ( 19 ), and the first pressing leg ( 11 ) is used for triggering an elastic arm in a locking structure to form a press-type trigger structure, and the second pressing leg ( 19 ) fits with a safety sleeve ( 20 ) and a press-down channel ( 17 ) to achieve a safety function of the trigger button ( 10 ); a barb ( 12 ) on the second pressing leg ( 19 ) fits with a self-locking hook ( 13 ) on the housing ( 1 ) so as to achieve a self-locking function after one press. In order to shorten the exposed needle length of a needle body on the needle core ( 2 ), in the automatic lancet, the distance between the second pressing leg ( 19 ) and the needle tip ( 7 ) is designed to be less than the distance between the first pressing leg ( 11 ) and the needle tip ( 7 ). Since the exposed needle length depends on the position of the safety sleeve ( 20 ), the exposed needle length is shortened, therefore the puncture performance increases, which enables the design of the lancet to be more reasonable and practical.

Apparatuses and methods are disclosed herein for extracting bodily fluids. The apparatus consists of a housing, a releasable lancet stored in the housing, an inlet flow channel formed in the housing, a mechanically powered vacuum generator, and a storage area formed in the housing. The releasable lancet is released to pierce the skin of the subject to allow fluid to be extracted from the subject. The vacuum generator generates a partial vacuum within the inlet flow channel. After the lancet has pierced the skin of the subject, the partial vacuum draws fluid from the subject and into the inlet flow channel. The storage area is in fluid connection with the inlet flow channel, and receives the fluid drawn from the subject from the inlet flow channel.

An apparatus includes a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing defines an inner volume and has an inlet port that can be fluidically coupled to a patient and an outlet port. The fluid reservoir is disposed in the inner volume to receive and isolate a first volume of a bodily-fluid. The flow control mechanism is rotatable in the housing from a first configuration, in which a first lumen places the inlet port is in fluid communication with the fluid reservoir, and a second configuration, in which a second lumen places the inlet port in fluid communication with the outlet port. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir. 139.-. (canceled)40. A blood transfer system , comprising:an access device at least partially insertable into a patient;a first tubing fluidically coupleable to the access device;a transfer device having an inlet port fluidically coupled to the first tubing, the transfer device having a seal member disposed at an end portion of a first fluid flow path and at least partially defining an inner volume, the inner volume receiving a first volume of blood flowing through the first fluid flow path toward the seal member when the transfer device is in a first state, the transfer device allowing a second volume of blood to flow from the inlet port via a second fluid flow path toward an outlet port while bypassing the inner volume when the transfer device is in a second state; anda second tubing fluidically coupleable to a sample reservoir external to the transfer device, the second volume of blood flowing from the second fluid flow path into the second tubing when the transfer device is in the second state.41. The blood transfer system of claim 40 , wherein the inlet port defines a lumen claim 40 , ...

BLOOD SAMPLE OPTIMIZATION SYSTEM AND BLOOD CONTAMINANT SEQUESTRATION DEVICE AND METHOD

Номер: US20220079483A1
Автор: Detloff John, Kang Gino, Rogers Bobby E.
Принадлежит: KURIN, INC.

Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber. 1. A blood sample control device comprising;an inlet configured to receive blood from the patient;an outlet;a chamber connected with the inlet and having a vent that includes an air permeable blood barrier; anda sampling channel having a distal end connected with the outlet;a junction connected between the inlet, the chamber and the sampling channel, the junction being sized and configured such that a first portion of blood conveyed from the patient flows into the chamber to displace air therein through the air permeable blood barrier, and such that a second portion of blood is allowed to bypass the chamber and the first portion of blood at least temporarily contained therein to be directed into the sampling channel toward the outlet.2. The blood sequestration device in accordance with claim 1 , wherein the air permeable blood barrier includes an air permeable material that at least partially seals upon contact with blood.3. The blood sequestration device in accordance with claim 1 , further comprising a housing that defines at least a part of each of the inlet claim 1 , the outlet claim 1 , the chamber claim 1 , and the sampling channel.4. The blood sequestration device in accordance with claim 3 , wherein the ...
