The priming attachment for a vacuum syringe can prevent air that is drawn out of the IV set and into the vacuum syringe from being released into the environment or back into the IV set. The priming attachment couples to the vacuum syringe and prevents the syringe plunger from reentering the syringe barrel. One embodiment of the priming attachment includes arms that fit inside the barrel and are pulled distally until they are released from the barrel. Once the arms released, the arms cannot reenter the barrel, which prevents distal movement of the plunger relative to the barrel. Another embodiment of the priming attachment includes a key that couples with a notch in a modified plunger. The modified plunger can rotate between a free position, where it can reciprocate within the barrel, and a locked position, where the notch aligns with the key and prevents translation of the modified plunger.
Systems and methods for providing gain-independent flow cytometry data are disclosed. In some implementations, sample median fluorescence intensities (MFIs) may be maintained irrespective of the gain detector settings. In some such implementations, the numerical scale used to represent MFI may correspond to the true intensity of the input signal. As a result, quality control (QC) procedures may instead focus on maintaining resolution performance of the flow cytometer. For example, the QC procedures may instead focus on maximizing a signal-to-noise ratio (SNR) for one or more photodetectors. In some such implementations, the frequency with which such QC procedures are performed may be reduced (e.g., from a daily procedure to a weekly or even monthly procedure). In some such implementations, it may be unnecessary to perform repeated QC procedures to ensure consistent sample MFIs over time.
Systems, methods, and computer program products for customized medical kit assembly and inventory management are disclosed. A method may include receiving, from a user device, an input associated with a selection of a set of medical devices for a medical kit. The set of medical devices may be dispensed from a storage location in response to receiving the input. The set of medical devices dispensed from the storage location may be packaged at a packaging location to form the medical kit. The medical kit may be dispensed from a fulfillment location.

Provided herein is a disinfecting device including: a substrate having a first side and an opposing second side and including a first material; and an indicator region embedded in the substrate, where the indicator includes a solvatochromatic material coated with a masking material embedded in the first side of the substrate.
A blood characteristic sensing system includes a light emitter, a light sensor, and a pressurizable cuff. The system encircles a sensing region of a patient appendage with the pressurizable cuff, emitting multiple discrete wavelengths of light into the sensing region and sensing amplitudes for each wavelength received through the patient appendage. A sensed plethysmogram value reflecting arterial volume is generated based on these sensed amplitudes, and pressurization of the cuff is modulated to partially clamp arterial volume within the sensing region via a closed-loop control algorithm based on the sensed plethysmogram value and a setpoint plethysmogram value. Differential absorption of the sensed wavelengths is used to produce a composition of analysis of arterial blood within the sensing region, and arterial blood pressure is sensed based on pressurization of the cuff required to partially clamp arterial volume.

A flow stop system is disclosed. A flow stop is configured, in a first position, to prevent a flow of a fluid through a tubing, and in a second position, to permit the flow of the fluid through the tubing, and a tubing fitment coupled to the flow stop and configured to receive the tubing and align the tubing with the flow stop. One or more conductive connections electrically are connected to a non-transitory machine readable memory, and the flow stop system is shaped to be loaded and engaged to a receptacle of an infusion device, and shaped to cause, when loaded and engaged, the one or more conductive connections to engage with one or more corresponding conductive connections provided by the infusion device.

A method of adjusting a position of an infusion container includes determining a current fluid pressure of a first fluid in a fluid path at or upstream of a fluid junction. When the determined current fluid pressure satisfies a predetermined threshold: display an indication of a fault condition associated with the current fluid pressure of the fluid being above the predetermined threshold. A motor operatively coupled to an adjustment device automatically changes a height of the infusion container, relative to a reference point, to an adjusted height that causes a reduction in a flow of the first fluid beyond the fluid junction, which mixes with a flow of a second fluid from the infusion container. The method includes determining an updated fluid pressure of the first fluid in the fluid path after the motor automatically changes the height of the infusion container to the adjusted height.
