A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.

An extraction operation room is provided. The extraction operation room is provided with a multi-stage Z-direction extraction arm and an X-direction pushing system. Movement on a multi-distance road section in a Z-axis direction is realized by using the multi-stage Z-direction extraction arm, such that the movement of an extraction member on the multi-distance road section in the Z-axis direction is realized, thereby greatly increasing the depth or length of the movement in a Z axis. The corresponding X-direction pushing system is provided, and the X-direction pushing system realizes the movement of a tank cover of a sample storage tank or a storage box in an X-axis direction. An operation space is given when the movement in the Z-axis direction and the X-axis direction are implemented, and meanwhile, the extraction structure is reasonable in design, small in occupied space, relatively low in cost, and convenient and intelligent to operate.

The present specification discloses collection kits for collecting a biological sample being handled by a chain-of-custody protocol and methods and uses for collecting a sample using such collection kits. In some aspects, a collection kit disclosed herein can comprise one or more identification labels, a sample collection device, one or more sample containers, and a collecting pouch. In some aspects, a collection kit disclosed herein can comprise one or more sample containers, a sample shipping container, one or more identification labels, and a collecting pouch.

A lifting basket, a lifting basket guiding mechanism and a lifting basket-type sample cryogenic storage device are provided. The guiding mechanism includes a storage member, an auxiliary guiding member and a driving member. The storage member is placed into a liquid nitrogen tank, provided with an opening at an upper end and sleeved onto an exterior of the lifting basket for restricting removal of a cryogenic vial storage member or a cryogenic vial stored inside the lifting basket. The auxiliary guiding member is arranged above the storage member and slidably connected to the storage member, and the auxiliary guiding member is sleeved onto the exterior of the lifting basket and is in contact with the lifting basket to perform relative sliding motion through a guiding structure. The auxiliary guiding member performs vertical motion relative to a storage frame and the lifting basket under the control of the driving member.

A container system and method for cryopreservation of sperm includes first containers having walls of a desired thickness and thermal conductivity. At least one layer of thermally insulating walls of a desired thickness and thermal conductivity is disposed around the at least one row of first containers. The first containers and thermally insulating walls are capable of being immersed from a range of about 5 C. to room temperature directly into a liquid cryogenic fluid below a surface thereof and freezing the sperm, without vitrification, at a cooling rate sufficient to maintain post-thaw quality of the sperm. The cooling rate is controlled solely by the thermal conductivity of the walls of the first containers, the layer(s) of thermally insulating walls and any substance between the walls of the first containers and the at least one thermally insulating container.

Devices and systems are provided for associating secondary materials with tissue grafts, both ex-situ and in-situ. The secondary materials may be medicants, an external cellular matrix factor, a cell, an enzyme, or an element or compound, such as oxygen. In a method, different secondary materials are delivered to a tissue graft via a delivery device at different times, such as at different stages of a healing process.

An embalming machine for mixing of fluids and cleaning of a reservoir may include a reservoir. The embalming machine may include a tube extending from a lower portion to an upper portion of the reservoir, the tube providing a pathway for fluid to travel to the reservoir. The embalming machine may include a port connected to an end of the tube adjacent to the upper portion of the reservoir, the port being configured to dispense the fluid traveling through the tube and into an interior of the reservoir.
