Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of analytes of interest, including hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection device 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 collection device also includes a test strip, and provides a closed fluid transfer mechanism to transfer the collected fluid from the swab to the test strip 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.

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.

A medical connector for connection to a corresponding medical connector is described. The medical connector includes a housing having a radial protrusion and a cavity, the cavity defined by a closed end, an open end, a partially cylindrical sidewall and a radial sidewall. The medical connector further includes an insert disposed within the housing, the insert including a locking tab having at least one thread on the inner wall of the locking tab and a recessed notch on the outer wall of the locking tab. The at least one thread of the locking tab engages at least one thread of a corresponding medical connector. Disposed within the cavity, the recessed notch rotates from a first position to a second position, wherein the second position contains a locking structure for non-removably securing the insert to the housing, while allowing for removal of the corresponding medical connector.

Detection systems for a syringe assembly that provide precision in monitoring the amount of fluid contained within the syringe barrel, detecting motion of the plunger within the syringe barrel, detecting the position of the plunger within the syringe barrel, and/or monitoring the volume received within or delivered by the syringe assembly are disclosed. A detection system of the present disclosure allows a sensor in communication with a portion of a plunger assembly to sense the motion of a plunger rod relative to a syringe barrel and thereby volume received within or delivered by the syringe by reading gradations having an identifier directly as the plunger rod with sensor moves past each respective gradation with identifier.

Collection device

A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing including a connector body positioned at the first end of the housing and configured to be secured to a syringe barrel, a cannula positioned within the housing, with the cannula defining a transfer opening and a valve opening, a seal arrangement positioned within the housing and movable within the housing, and an aspiration assembly comprising an aspiration housing defining an aspiration opening, a filter received by the aspiration housing, and one-way valve received by the aspiration housing, where the valve opening of the cannula is positioned within the aspiration housing, and where air is configured to flow into the filter via the aspiration opening, into the one-way valve, and into the valve opening of the cannula.

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.

An infusion pump () for delivery of a fluid is disclosed. The infusion pump allows a user to selectively control a flow rate of a fluid and includes a spike member () that is connectable to an injection port of an intravenous fluid container ().

Sampling systems and techniques that increase pickup efficiency and shedding efficiency of an analyst of interest collected from a surface are provided. In one aspect, an absorbent swab collects an analyte of interest, such as a hazardous contaminant, from a test area demarcated by a template. The sampling techniques can include swab speed and force protocols specifying how fast and how hard the user should apply the swab across the surface to improve pickup efficiency. The sampling techniques can include instructions for inverting a container enclosing the swab and collected contaminant to improve shedding efficiency from the swab.

Aspects of the disclosure relate to augmented reality devices for generating a composite scene including a real-world test environment and an augmented reality overlay visually representing a test area of the environment. Some devices can include wearable displays for displaying an overlay to a user, and other devices can include projectors for illuminating the test environment with the overlay.
