Cage for preparing rat model of ischemic hypoxic encephalopathy and feeding device

Abstract

The invention relates to the field of medical auxiliary instruments, in particular to a cage for preparing a rat model of ischemic hypoxic encephalopathy. The cage for preparing the rat model of the ischemic hypoxic encephalopathy comprises a box body, a cover body, a first sliding block, a first driving mechanism, a second sliding block and a second driving mechanism; an opening is formed in theupper side of the box body, a first air inlet pipe and a second air inlet pipe are arranged on the box body, the first sliding block is arranged in the box body in a sliding manner; the first drivingmechanism is arranged in the box body and is connected with the first sliding block; the second sliding block is arranged on the first sliding block in a sliding manner, and an air blowing pipe communicated with the second air inlet pipe is arranged on the second sliding block; the second driving mechanism is arranged on the first sliding block and is connected with the second sliding block; the cover body is buckled at the upper side of the opening, and an image acquisition device and an exhaust pipe are arranged on the cover body; and a controller is also included and is in communication connection with the image acquisition device, the first driving mechanism and the second driving mechanism. Through the arrangement mode, the oxygen concentration in the box body can be uniform, and theconsistency of the rat model is good.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a cage for preparing a rat model of hypoxic-ischemic encephalopathy and a feeding device. Background technique [0002] Hypoxic ischemic encephalopathy (HIE) is a brain lesion caused by ischemia and hypoxia of brain tissue caused by various reasons. The most common is hypoxic ischemic encephalopathy in neonates, but it can also occur in other age groups. Neonatal ischemic hypoxic encephalopathy is a brain lesion caused by hypoxia in newborns during the perinatal period. Common causes include fetal distress caused by various reasons, such as umbilical cord around the neck, abnormal amniotic fluid, etc. It is also common in childbirth Asphyxia and hypoxia during and after birth, a few can be seen in brain damage caused by other reasons. The disease mostly occurs in full-term infants, but can also occur in premature infants. The fetal heart rate may increase or...

Problems solved by technology

[0004] However, there are no cages specially used for hypoxia treatment at home and abroad, and most of them are self-made with storage boxes, resulting in high animal mortality and poor model consistency.
