The Oximeter is non-invasive device intended for spot-checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). The portable fingertip device is indicated for adult patients in home and hospital environments (including clinical use in internist/ surgery, anesthesia, intensive care, etc).

The Oximeter is intended for spot-checking of functional pulse oxygen saturation (SpO2) and pulse rate (PR) of adult patients in the home and hospital. The oximeter features a small size, low power consumption, a convenient operation, and portability. It is only necessary for a patient to put one of his/her fingers into the fingertip clips for measurement. Principle of the oximeter as follows: A mathematical formula is established making use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobin (RHb) and Oxyhemoglobin (HbO2) in red and infrared zones. Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that two beams of different wavelength of lights (660nm red and 905nm infrared light) can be focused onto a human nail tip through a clamping finger-type sensor. Relevant data is shown on the Oximeter's display through electronic circuits and a microprocessor. The four models (JZK-301, JZK-303, JZK-305, and JZK-307) have the same intended use, working principle, characteristic, and conformance standards, only in appearance have some different (appearance design, dimension, and weight).

The Infrared forehead thermometer (Models JZK-602, JZK-603) is a non-contact infrared thermometer intended for the intermittent measurement of human body temperature from forehead at a distance of 1-5cm for people of all ages. The device is reusable for home use and clinical use.

Infrared forehead thermometers (includes model JZK-602, JZK-602, JZK-603) are intended to measure the body temperature through receiving infrared energy radiation via the forehead for people of all ages. These thermometers have the capability to measure temperature via body mode or object mode, and the temperature is directly shown on the LCD display. These thermometers have the following features: 1) The device is intended to be reusable for home use and clinical use. 2) The device is mainly composed of infrared sensor, signal receiving processor, kevs, buzzer, LCD display. 3) Switching of temperature unit between °C and °F. 4) The latest 32 sets of memory for measuring human body and object; the user can view or delete the previous measurement results. 5) Buzzer on or off to set the prompt tone on or off. 6) Prompt tone function and backlights function. 7) The prompt limit setting function. 8) Low battery indication, and auto power-off.

This Upper Arm Blood Pressure Monitor is intended to measure the systolic and diastolic blood pressure as well as the pulse rate of adult person. It can be used at medical facilities or at home.

The Upper Arm Blood Pressure Monitor, including ZK-B869, ZK-B869, ZK-B872 and ZK-B876, can automatically complete the inflation and measurement, which can measure systolic and diastolic blood pressure as well as the pulse rate of adult person with arm circumference ranging from 22 cm to 32cm by the oscillometric technique. User can select the blood pressure unit mmHg or KPa. The initial inflation pressure of the cuff is zero pressure. When start the device, the cuff will be inflated and deflated. The device consists of the microprocessor, pressure sensor, operation keys, pump, deflation control valve, LCD screen and arm cuff. The ZK-B868 is powered by 4 AA dry batteries (DC 6V), other models are powered by 4 AAA dry batteries (DC 6V). The device has a memory function that automatically stores some sets data of the latest measurements. It can also display the latest measurement result. Additionally, the device also can read the data through voice broadcast function. The four models have the same intended use, working principle, measuring range, accuracy, cuff, conformance standard; only in appearance and power supply have some difference.
