Working Principle
SpO₂ sensors are essential devices for medical monitoring. They noninvasively measure SpO₂ and pulse rate in real time, providing critical data for clinical diagnosis and health management. The sensors emit red (660nm) and infrared (940nm) light through the skin (e.g., fingers and earlobes). Hemoglobin's light absorption rate varies with oxygen content, and the sensor calculates SpO₂ by measuring the intensity of the reflected and transmitted light.
As a core tool for accurately monitoring SpO₂ sensors, it is divided into two categories: disposable and reusable.
Plinma Technology is committed to providing reliable blood oxygen monitoring solutions for clinical practice. Its blood oxygen probes, equipped with high-precision sensors, provide real-time, continuous, and accurate monitoring of patients' SpO₂. Crafted from medical-grade TPU, and flexible, skin-friendly materials, and feature double shielding to ensure accurate and stable blood oxygen measurement, . Plinma Technology's diverse product offerings meet the needs of diverse surgical scenarios, providing reliable support for medical monitoring.
Common types
Finger clip type
Featuring a mature and classic design, it offers a wide range of compatibility with a variety of mainstream monitoring devices. Durable materials used in the housing and other components ensure it withstands frequent use. Its long service life reduces the cost and inconvenience of replacing equipment due to failure.
Drawing on the classic design concepts and technological advantages of Nihon Kohden products, the product emulates these in performance and user experience, making it ideally suited for medical equipment systems and meeting the demand for high-quality blood oxygen monitoring accessories. The downward-facing design provides ergonomic fit and facilitates easy operation for medical staff and users, especially when monitoring patient blood oxygen levels. This allows for smoother and quicker attachment of the probe to a finger or other location, enhancing ease of use and efficiency.
Soft tip
Utilizing advanced sensor technology, this probe outperforms other similar Spo2 probes on the market in signal acquisition and processing. Its unique thin design minimizes pressure on the patient compared to thicker Spo2 oximetry probes, allowing for unrestricted movement without affecting finger motion.
The strap features a special buckle that securely secures the blood oxygen sensor to the newborn's area, effectively preventing it from falling off due to unconscious movements. Made of extremely soft and delicate medical-grade material, it protects the newborn's skin.
Ear clip-on
Designed based on the physiological structure of the human ear, it significantly reduces external interference, providing highly reliable and accurate measurement data. It also offers fast measurement speeds, typically providing adult SpO₂ and pulse rate results within 5-10 seconds.
The probe is usually clamped on the animal's earlobe, tongue, toes and other parts of the body. Considering that the animal may scratch, shake and other behaviors during the measurement process, the probe uses a sturdy and durable shell material with certain impact and wear resistance.
Application
In hospitals, SpO₂ are essential equipment components in intensive care units (ICU), operating rooms, and general wards. They can monitor SpO₂ and pulse rate in real time for postoperative patients, those with respiratory and cardiovascular diseases, and can promptly identify changes in their condition. This helps medical staff assess postoperative recovery and provide a basis for adjusting treatment plans.
