Problems solved by technology

[0003] However, the traditional low-temperature refrigeration method mostly uses a low-temperature refrigerator. When the user takes the bone flap and some medicines used in conjunction with the bone flap out of the refrigerator, because people hold the door with one hand, the refrigerator is opened with the other hand. It is difficult to free up your hands to take out two kinds of objects at the same time. You need to take one of the objects to the temporary storage device first, and then take the next object again. This is not only a waste of time, but also a long waiting time. Frozen objects are exposed to the air for a long time, which increases the speed of temperature rise, which has a greater adverse effect on the bone flap and accessories after cryogenic freezing, and directly affects the subsequent surgical treatment

Embodiment 2

[0047] In this embodiment, a deep cryopreservation method for collecting, processing and storing autologous skulls is proposed, which includes the following steps:

[0048] Step a, pretreatment: take out the skull bone flap from the donor, and remove the periosteum and other tissues on the bone flap;

[0049] Step b, flushing: repeatedly flushing the skull block with physiological saline to remove residual blood stains therein;

[0050] Step c, pre-freezing: Put the skull block into a vacuum freeze dryer, and freeze-dry it for 1 hour at a temperature of -2°C for vacuum freezing;

[0051] Step d, preparation of gel: dissolving polyvinyl alcohol (PVA) in deionized water above 90°C to form a PVA aqueous solution, dispersing nano-hydroxyapatite (n-HA) with ultrasonic waves, and then pouring it into the PVA aqueous solution to form Composite solution, stir evenly, after defoaming, pour the composite solution into the mold, and put it into the freezer for freezing, then melt the fr...

Abstract

The invention provides an autologous skull collection, treatment and storage device and a profound hypothermia preservation method. The autologous skull collecting, processing and storing device comprises a profound hypothermia refrigerator body; two bridging plates both fixedly mounted on the outer wall of one side of the deep hypothermia refrigerator body; a double-section screw rod rotationally mounted on the sides, close to each other, of the two bridging plates; two fixed connection seats both fixedly installed on the outer wall of one side of the deep hypothermia refrigerator body, wherein the double-section screw rod penetrates through the fixed connection seats and is movably connected with the fixed connection seats; two bearing plates respectively hinged to the two fixed connection seats; and two placing grooves. The autologous skull collection, processing and storing device and the profound hypothermia preservation method have the advantages that the skull flaps and accessories are convenient to take, the air exposure time of objects is shortened, the temperature rise speed of the objects is slowed down, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of skull storage, in particular to an autologous skull collection, processing and storage device and a cryopreservation method. Background technique [0002] At the present stage, during craniocerebral trauma and brain surgery, it is sometimes necessary to remove the skull bone flap according to the specific condition of the disease, in order to repair the brain next time. After the bone flap is removed, the bone flap often has There are two storage methods. One is that the patient directly brings the bone flap back and stores it in a low-temperature freezing method. The other is to store the bone flap through a medical institution or a special storage institution, so that the bone flap can be professionally stored. Use has beneficial effects. [0003] However, the traditional low-temperature refrigeration method mostly uses a low-temperature refrigerator. When the user takes the bone flap and some medicine...
