Abstract: A disposable staining system is provided including an insertable module configured to receive a biological sample therein, the insertable module including a well in which the biological sample is positioned; and a staining cartridge configured to receive the insertable module including the biological sample therein, the insertable module being positioned in the staining cartridge. The insertable module has first and second inclined planes on opposing sides of an upper surface of the insertable module. A sled configured to receive the insertable module has corresponding first and second inclined planes on a bottom surface thereof. The first and second inclined planes of the insertable module and the first and second inclined planes of the sled are configured to transform horizontal movement of the insertable module into the staining cartridge into a vertical movement of the sled such that the sled is pushed upward.

Abstract: A system for delivery of liquid to and removal of liquid from a sample is provided. The system includes a primary device that contains the sample and at least one valve configured to allow liquid to be delivered to and removed from the sample; at least one reservoir that is configured to receive a volume of liquid; a secondary device including at least one port configured to receive the at least one reservoir and configured to be coupled to the primary device; and a tertiary device configured to receive the secondary device and comprising mechanical modules that deliver the volume of liquid from the at least one reservoir to the sample and remove the volume of liquid from the sample. Positioning the primary device in the secondary device causes the volume of liquid in the at least one reservoir to be delivered to the sample contained within the primary device.

Abstract: An apparatus for selectively coupling a first tube and a second tube allows easy separation and connection of tubing in cases of accidental or forceful removal of the tube. A first connecting member and a second connecting member can be easily connected and disconnected as needed to prevent and allow fluid flow to and from a patient. The apparatus can be applied to prevent the accidental removal of patients undergoing extended treatments involving tubes entering the body in the clinical, geriatric, or other care settings. The apparatus also allows for the purposeful detachment and sealing of tubes entering the body to allow for increased patient mobility.
