Description

Technical Field

[0001] The utility model relates to the technical field of small animal ear temperature measurement, in particular to a novel backpack small animal ear temperature measurement device. Background Art

[0002] Body temperature, heart rate and blood pressure are the three most important parameters of animal vital signs. Body temperature is a direct response to metabolism, and any abnormality may indicate the onset of disease. In the medical field, the temperature of the heart, lungs, internal organs, and brain is considered to be the core body temperature. Currently recognized methods of measuring core body temperature include blood temperature, bladder temperature, anal temperature, and tympanic membrane temperature. Core body temperature is an important indicator for accurate analysis of pathology and health.

[0003] The existing real-time measurement devices for the core body temperature of small animals on the market mainly use temperature measuring capsules, which are implanted into the body of small animals to measure the core temperature of internal organs. Traditional temperature measuring capsules have built-in temperature measurement transmission modules, batteries, temperature sensors, external signal receivers, etc. After the temperature measuring capsules are activated, they are implanted into the abdominal cavity of living small animals. The temperature of the core organs is detected in real time through the temperature sensor, which is converted into an electrical signal and connected to an external receiver through the temperature measurement transmission module. The external receiver processes the electrical signal to obtain the real-time core body temperature of the small animal. However, the existing technology has some limitations and problems:

[0004] First, due to the size limitation of the temperature capsule, the built-in battery is usually small and cannot be replaced. As a result, the standby time of the temperature capsule is limited and it cannot work continuously for a long time. Secondly, the wound repair of the temperature capsule implantation surgery for small animals takes a long time, which means that during the recovery period after the surgery, the temperature measurement window period is short, and the signal may be lost during the experiment, resulting in data loss. At the same time, foreign objects implanted in the abdominal cavity of small animals may compress the organs and affect their normal physiological functions. The implantation surgery of the temperature capsule itself may cause certain interference to the expected detection indicators and affect the accuracy of the experimental results. Therefore, a new backpack ear temperature measurement device for small animals is urgently needed. Utility Model Content
