The present disclosure relates to capillary blood sampling. In one aspect, the present disclosure provides a finger lancing device comprising a body having a chamber for receiving a finger and a lancing device comprising a lancing member actuator for actuating a lancing member to lance a finger received in the chamber.

In certain instances, an access system includes a connector to couple with a closed intravenous catheter system that includes a valve and a catheter tube. The access system can include a reinforcement member fixedly secured to the connector so as to be immobile relative thereto and oriented such that when the connector is coupled with the closed intravenous catheter system, a distal tip of the reinforcement member is at or proximally spaced from a proximal surface of the valve. The access system can include a cannula movable relative to the reinforcement member from a retracted position to an advanced position. At least a portion of the cannula can be advanced distally through the reinforcement member and then through the valve and subsequently into the catheter tube as the cannula is transitioned from the retracted position to the advanced position.

A blood draw device including an introducer and an actuator. The introducer has a proximal end portion, a distal end portion, and an inner volume, and includes a top surface having a first portion of a first length and a second portion of a second length. The first portion may have a smooth surface along the first length and the second portion has a plurality of ridges along the second length. The actuator includes an exterior portion positioned above the top surface and an interior portion positioned within the inner volume, wherein the exterior portion of the actuator includes an engagement member and a downwardly-extending tab projecting below the engagement member such that the downwardly-extending tab of the actuator may contact at least the plurality of ridges of the second portion of the introducer to provide at least one of tactile and audible feedback to a user.

A dermal patch for collecting a physiological sample includes a housing with a collection chamber, a sample channel and a pin within a receptacle of the housing. The sample channel is configured to direct a physiological sample drawn from a subject to the collection chamber. The pin is removably positioned within the receptacle and is configured to move from an undeployed position to a deployed position. The pin is configured to seal the receptacle when in the undeployed position and is further configured to facilitate generation of negative pressure in the sample channel when the pin is moved from the undeployed to the deployed position.

According to some embodiments, a medical instrument (for example, an ablation device) comprises an elongate body having a proximal end and a distal end, an energy delivery member positioned at the distal end of the elongate body, a first plurality of temperature-measurement devices carried by or positioned within the energy delivery member, the first plurality of temperature-measurement devices being thermally insulated from the energy delivery member, and a second plurality of temperature-measurement devices positioned proximal to a proximal end of the energy delivery member, the second plurality of temperature-measurement devices being thermally insulated from the energy delivery member.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.

It is known in the art to use an apparatus to enhance the visual appearance of the veins and arteries in a patient to facilitate insertion of needles into those veins and arteries. This application discloses a number of inventions that add additional data collection and presentation capabilities to a handheld vein enhancement apparatus and a set of processes for the collection of blood and the delivery of IV medicines that use the handheld device to mediate the process.

Provided is a packaging container including a bag main body portion having a first surface, a second surface and an opening portion; and a tongue piece portion formed to be continuously extended from the first surface. The bag main body portion and the tongue piece portion have an aluminum vapor-deposited layer on an outside thereof, the packaging container further includes an adhesion portion which is provided on the second surface to be spaced from the opening portion; and a folded-back portion which is provided between the adhesion portion and the opening portion to fold back the tongue piece portion to the opening portion side. A length of the tongue piece portion is a, a length from the opening portion to the folded-back portion is b, and a length from the folded-back portion to the adhesion portion is c. And,
a<b+c.

A method for thrombus detection comprising employing an elongate tube having at least one opening at a distal end of the elongate tube. A coupling is attached or formed at the proximal end of the elongate tube. The detection of the presence of a thrombus is performed by using a syringe to withdraw blood through the at least one thrombus detection opening at the distal end of the elongate tube. If little or no blood is withdrawn, or if the withdrawal of blood is more difficult than expected, the presence of a thrombus obstructing the openings is indicated.

An apparatus for the uninterrupted administration of fluid to an animal body during clean blood collections is disclosed. Embodiments include an intravenous device defining a first fluid channel, wherein the first fluid channel is configured to selectively transport IV fluid to an animal body and draw a bodily fluid from the body, and a connection member configured to connect to a catheter to the first fluid channel and defining a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface is shaped to create a fluid flow pattern that quickly and completely removes residual bodily fluid remaining at the concave distal end. Embodiments include a concave surface defining an asymmetric funnel shape, a vertex of which is centered on the first fluid channel.
