Abstract: Medical lavage devices are described. Devices include a container that can retain a lavage liquid and an outlet through which a lavage liquid carried by the container can be delivered. Devices also include a light source that is retained relative to the outlet such that the light (e.g., white light, UV light) from the light source can illuminate a liquid delivery area, i.e., an area through which liquid will pass or be delivered following exit from the container via the outlet. A device can optionally include a pump for moving liquid through the outlet and/or an attachment at the outlet, e.g., a luer lock, that can be used to attach an accessory, e.g., a delivery catheter to the device. A device can include one or more accessory components, e.g., a splash guard, a magnifying lens, a penetration depth guard, etc., to improve or modify the liquid delivery characteristics of the device.
