Description

TECHNICAL FIELD

[0001] The utility model relates to the field of macroscopic specimen preservation technology, and specifically relates to a macroscopic specimen box with pressure sensing function. BACKGROUND

[0002] Teaching specimens are usually divided into traditional physical specimens, plasticized specimens and three-dimensional image specimens. Although plasticized specimens and three-dimensional digital images have no formaldehyde smell and are easy to preserve, their accuracy and authenticity are currently poor, which affects the teaching effect. Traditional physical specimens can accurately and truly achieve the teaching purpose, but they are generally preserved with formalin solution. Teachers and students in the course will have severe irritation and edema of the cornea and respiratory tract, which is extremely harmful to health.

[0003] In the process of dissection teaching demonstration, the macroscopic bottled specimen has many advantages such as clean appearance, beauty, real easy to observe, clear and complete structure. The macroscopic bottled specimen also has some defects. Because organic glass or acrylic plate is generally used for adhesion through tetrachloromethane. If stored for a long time, air will enter the specimen box, which will make the fixed liquid turbid and denature, and the specimen will rot and the structure will become blurred. In the daily storage process, it is difficult to find the air leakage condition of the specimen with small pores at the first time. When discovered, the liquid has already flowed out or become turbid. The macroscopic bottled specimen is very expensive, and it takes a long time to make a complex specimen. If it cannot be handled in time due to poor sealing performance, it will cause the course to be unable to proceed normally, and will cause great economic loss to medical colleges or medical units, and more seriously, will cause harm to the health of teachers or students.
