Aspects of the disclosure relate to lateral flow assays having a number of different detection zones tuned to extend the dynamic range of the assay in indicating concentration of a hazardous contaminant in a test sample. Some aspects relate to assay reader devices configured with instructions to generate a result representing the concentration of the hazardous contaminant in the test sample based on some or all of the detection zones.

High dynamic range assays in hazardous contaminant testing

An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

IV flow management systems and methods

Aspects of the disclosure relate to demarcation templates for demarcating a test area on a test surface and for providing visual guidance to a user to precisely and accurately swab the test surface in order to determine the presence and/or concentration of an analyte of interest on the test surface. In one aspect, the analyte of interest is a hazardous contaminant. Some templates can include alignment markings around the border demarcating the test area to provide such guidance to users, and can include graphical use instructions on a removable central portion of the template. The template can be adhesive to be securely fixed to the test surface for accurate demarcation of the test area throughout sampling.

Demarcation template for hazardous contaminant testing

An activator attachment that can be attached to the proximal end of a catheter adapter and can activate a blood control valve within the catheter adapter.

Activator attachment for blood control catheters

A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

Systems and methods of facilitating instrument delivery to a catheter assembly

Collection device

A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.

Intravenous catheter assembly with safety clip

A syringe assembly includes a syringe and a vibrator configured to vibrate at at least one frequency to reduce stopper friction. The vibrator is attached to the syringe. The syringe assembly may further include an infusion pump configured to draw fluid from the syringe with a negative pressure.

Syringe pump vibration module to reduce stopper friction

A needle protection device may include a hub, a housing disposed within the lumen of the hub, and a needle. The housing may include a tubular portion, which may include two arms coupled thereto. Each of the arms may include a first end coupled to the tubular portion, a second end disposed within the tubular portion, and a bent portion therebetween. The second end of the first arm and the second end of the second arm may form a duckbill valve. A needle may extend through the housing. Withdrawing a sharp distal tip of the needle in a proximal direction beyond the second end of each of the arms may close the duckbill valve and facilitate removal of the housing from the hub. Shielding the sharp distal tip of the needle in this manner may prevent blood spatter and exposure to blood and blood-borne pathogens.

Needle protection device and related systems and methods

A syringe is provided. The syringe includes a syringe barrel including an open proximal end, a closed distal end, and a sidewall extending therebetween. The syringe also includes: a plunger having an annular sidewall configured to seal against an interior surface of the sidewall of the syringe barrel, the plunger being configured to move through the syringe barrel in proximal and distal directions; a pump in fluid communication with an interior volume of the syringe barrel, the pump being configured to draw fluid from the syringe barrel; and a nozzle including a lumen in fluid communication with the pump and configured to receive fluid drawn from the syringe barrel by the pump and to expel the fluid through a distal end of the lumen. The pump can be a valve-less piston pump.

Self-pumping syringe

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

Hazardous contaminant collection kit and rapid testing

A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90&#xb0;.
