The invention relates to a mixture of polyoxymethylene dialkyl ethers (POM) having a specific molecular distribution of n as well as its preparation method.

The invention also relates to a composition comprising: a) a mixture of polyoxymethylene dialkyl ethers (POM) having a restricted specific molecular distribution b) at least one biocidal agent c) at least one pro-penetrating agent d) at least one dye e) optionally, another additive
and water as diluent,

It also relates to a non-therapeutic method of preserving and/or embalming a dead human or animal body using the composition, such as the use of this composition for anatomopathological purposes.

A human tissue isolation pouch for use with a sealer machine to indirectly seal human tissue medical pouches while avoiding cross contamination is herein disclosed. The human tissue isolation pouch comprises a rigid frame supporting a high temperature material and having one or more magnets for removably attaching the human tissue isolation pouch to a sealer machine. During use a medical pouch, which may contain a human tissue sample, is inserted within the human tissue isolation pouch. The jaws of the sealer machine clamp down directly on the high temperature material, thus indirectly heating and sealing the medical pouch inside the human tissue isolation pouch. The sealing machine jaws do not physically contact the medical pouch at any time during the sealing process, and in this way contamination of the sealer machine (and cross contamination of medical pouches from distinct donor cases) is avoided. The rigid frame of the human tissue isolation pouch may be sterilized after each donor event. And the containment bag formed of a high temperature material may be disposed of after each donor event.

The positioning of the mandible clamp within the person's jaw or mouth is accomplished by either of two embodiments. One embodiment uses a pair of flanged surface that allow a person to push a barb through the person's gum structure on the upper jaw and lower jaw. This first embodiment contemplates use for a period who has natural teeth at the time of death. The second embodiment resembles a clamp that is placed over the person's gum to secure the jaw bones together. This second embodiment is used with person's who did not have natural teeth at the time of death. After the respective openings are placed over the gum areas of the person's upper and lower gums a tension member slides over the outside surface of the clamp to produce gripping of the gum by the device. A plurality of gripping knobs is provided to produce additional grip on the person's gums.

Today's funeral practices are unsustainable, toxic, and polluting. Both cremation and the manufacture and transport of caskets, grave liners, and headstones emit greenhouse gas emissions into the atmosphere. In fact, the very last thing that most of us will do on this earth is poison it. As a response, a system and method called recomposition that gently and naturally returns humans to the earth after death.

A tube-array-type liquid nitrogen container includes a container body having a mouth; a tube array component received in the container body; and a top cap sealing the mouth from above. The top cap is rotatable in the mouth. The tube array component is composed of a plurality of holding tubes. The holding tube is opened at one end thereof, wherein the opening thereof faces the top cap. The top cap has at least one tube access passing therethrough. Each tube access is atop covered by a tube access cover. The tube-array-type liquid nitrogen container uses a tube-array component composed of the a plurality of holding tubes to store the freezing tubes, and is cooperated with the rotatable top cap and an external robotic arm, thereby improving space utilization and thermal insulation, effectively ensuring safety of the freezing tubes, and facilitating automatic storage of freezing tubes.
