A Century Of Development in Veterinary Monitors

In the early stages, animal diagnosis and treatment lacked dedicated monitoring equipment. Veterinarians could only rely on manually checking pulses, listening to the heart, and visually assessing respiration to judge an animal's condition, resulting in significant errors and persistently high risks associated with anesthesia and surgery. Some research institutions directly used human electrocardiographs to monitor cattle, horses, dogs, and cats. However, the differences in heart rate and blood oxygenation ranges between humans and animals were enormous, the equipment lacked adaptive algorithms, and hair and limb movement easily caused signal interference, leading to severe data distortion. This stage only allowed for basic, rough observation of electrocardiogram waveforms; there were no blood oxygenation or non-invasive blood pressure modules, and no data storage capabilities. It was only used for large-scale livestock research and was completely unavailable to ordinary pet clinics and farms. Sudden shock and respiratory failure during surgery often went undetected in time.

With the rise of the companion animal medical industry, manufacturers have launched prototype veterinary monitoring devices with targeted modifications, marking the industry's formal entry into a professional stage. The devices have simplified adaptation to animal physiological thresholds, are equipped with sensor probes of different sizes for animals of varying sizes, and feature dual-channel monitoring of body temperature and respiration. Blood oxygenation detection technology has also been implemented, filling the gap in blood oxygenation monitoring during anesthesia. However, the devices still have significant shortcomings: most are split-type units with small screens, rely on mechanical knobs for operation, and lack digital storage; non-invasive blood pressure measurement modes are limited, supporting only manual measurement and not continuous monitoring; the devices are bulky and inconvenient to move; imported devices are expensive, resulting in extremely low market penetration in China, with only a few high-end animal hospitals adopting them.

Microelectronics and digital image processing technologies drove a comprehensive upgrade of the industry. Multi-parameter integration became mainstream, with a single device simultaneously monitoring five core indicators: ECG, blood oxygen, non-invasive blood pressure, body temperature, and respiration. New features included arrhythmia analysis and waveform playback. Color LCD screens replaced monochrome displays, and automatic, continuous, and manual blood pressure measurement modes met the needs of various scenarios, including surgery, emergency rooms, and inpatient care. After 2015, domestically produced equipment accelerated its breakthroughs, breaking the monopoly of overseas brands. Touchscreen models were launched, featuring large-capacity built-in storage to save blood pressure records, waveform curves, and alarm logs. Multilingual systems were adapted for the global market, and modular components facilitated replacement and maintenance. Equipment was further subdivided into 8-inch, 12.1-inch, and 15-inch models. Portable models were chosen for small clinics, while large-screen, high-end models were equipped for intensive care animal hospitals, covering all levels of diagnostic and treatment needs.

Currently, veterinary monitors are becoming increasingly intelligent, equipped with dedicated animal filtering algorithms. Even in agitated or low-perfusion conditions, they accurately collect data, featuring a three-level multi-alarm system with audio, visual, and text alerts to immediately notify healthcare professionals of any abnormal signs. Built-in lithium batteries, wireless data transmission, and trend chart storage are now standard features, making them suitable for all scenarios including surgical anesthesia, emergency resuscitation, routine checkups, and postoperative monitoring.

Throughout its development, veterinary monitors have undergone four technological upgrades: from manual visual assessment to single-parameter individual monitoring, digital integration, and modular, expandable intelligent devices. The Multi-Parameter Veterinary Monitor breaks through the limitations of traditional equipment's fixed functions; a single main unit can be upgraded with monitoring modules as needed, balancing cost-effectiveness and clinical practicality. Domestically produced multi-parameter monitors, represented by the Multi-Parameter Veterinary Monitor, accurately match the diagnostic and treatment needs of animals of all sizes, promoting the standardization of animal anesthesia and intensive care, and becoming an indispensable basic device in modern animal medicine.
