Silica gel hypothermia model-making animal experimental device

Abstract

The purpose of the invention is to provide a silica gel hypothermia model-making animal experimental device which is stable in preparation, high in repeatability and easy to operate. The silica gel hypothermia model-making animal experimental device selects an animal experiment convex table made of stainless steel; and a table top with suitable table top width can be selected according to size ofan animal. Moreover, the animal experiment convex table has a table top constant-temperature function, as well as animal limb fixtures. The silica gel hypothermia model-making animal experimental device adopts combination of soft silica gel hypothermia heating sheets with portable elastic bandages as hypothermia animal modeling tools, so that hypothermia injury models in accordance with clinical requirements can be made by just attaching the silica gel hypothermia heating sheets to the animal skin. The silica gel hypothermia model-making animal experimental device is capable of preparing accurate and reliable animal hypothermia models; and moreover, automatic digital display control can be realized by just setting temperature and time without damages on animal skin, and can be operated atany part of the animal skin, thereby facilitating preparation of hypothermia models of different sizes and different depths.

Description

technical field [0001] This application relates to a low-temperature burn that has a low base temperature but the skin is in contact with a low-heat object higher than body temperature (37°C) for a long time, resulting in heat accumulation and scalding of the skin and subcutaneous tissue at the contact site, which is called low-temperature burn. A treatment model for low-temperature scalds with difficult-to-heal wounds, especially a silica gel low-temperature modeling animal experimental device. Background technique [0002] Low-temperature burns can also be called low-temperature burns, which are progressive damages from the superficial layer of the skin to the deep layer of the dermis and subcutaneous tissues. It is generally believed that continuous contact with a heat source at 70°C for 1 minute can cause full-thickness damage to the epidermis; continuous contact with a heat source at 40°C for 6 hours can cause irreversible damage to the basal cells of the skin. The tem...

Journal of Lanzhou Medical College, Volume 27, No. 1, March 2001, Liu Yi, Xue Xiaodong, Jia Chiyu, et al. "Experimental research on the establishment of a mouse scald model with a constant temperature and constant voltage electric scald instrument". Its heating temperature is fast and cooling is slow, and the electric iron block is unstable and the pressure is uneven when the hand is held for a long time, and the plane of the electric iron block and the animal skin plane cannot reach the same plane pressure, and the uniform injury model cannot be reproduced. Low temperature injury modeling methods vary greatly

The patent document with the patent application number CN201710943082.7 discloses "a portable digital temperature-controlled scald instrument", which is used for high-temperature scald animal experimental equipment, and is suitable for the production of common skin scald models of mice, rats, rabbits, and miniature pigs. ; The three documents retrieved above are all suitable for making animal burn models, but they are far from low-temperature burn model making methods, and low-temperature burns are slowly and gradually damaged from the superficial layer of the skin to the deep layer of the dermis, and the degree of damage is related to the low-temperature exposure time relevant
