Description

Technical Field

[0001] The utility model belongs to the technical field of biological plastination, and specifically relates to a specimen deep gas hardening device based on a plasticizing and hardening link. Background Art

[0002] Plastination is a technique used in anatomy that removes body fluids and fat in a vacuum through four steps: fixation, dehydration, forced infiltration, and hardening. These fluids and fat are then replaced with polymers such as silicone and epoxy resin. The processed specimens no longer decay or have an odor, and retain most of the characteristics of the original sample.

[0003] During the hardening process of bioplastination technology, the deep layer of the specimen often hardens slowly or does not harden at all. Utility Model Content

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] A specimen deep gas hardening device based on a plasticizing and hardening process, comprising:

[0006] A solution tank for holding a catalyst solution, wherein a pressure gauge is provided on one side of an upper portion of the solution tank, and a connection between the solution tank and the pressure gauge is located above the liquid level of the catalyst solution in the solution tank;

[0007] An injection tube, one end of which is connected to the upper portion of the solution tank and the other end of which is provided with a needle for insertion into the deep muscle of the specimen, wherein the connection between the injection tube and the solution tank is located above the liquid level of the catalyst solution in the solution tank;

[0008] A compressed air injection pipe, one end of which extends below the liquid level of the catalyst solution in the solution tank, and the other end of which is connected to an air compressor.

[0009] Furthermore, a first valve is provided on the injection tube.

[0010] Furthermore, an exhaust pipe is provided on the upper portion of the solution tank, and a second valve is provided on the exhaust pipe.

[0011] Furthermore, a drain pipe is provided at the bottom of the solution tank, and a third valve is provided on the drain pipe.

[0012] Furthermore, a fourth valve is provided on the compressed air injection pipe.

[0013] Beneficial effects of the utility model:

[0014] The utility model changes the original long-time specimen hardening speed. Through the device, the inner and outer parts of the specimen to be hardened can be hardened at the same time, thus shortening the hardening time and avoiding the glue flow phenomenon.
