damage that may affect patient’s safety and monitoring performance. It is recommended
that the device is inspected at least once a week. When there is obvious damage, stop
using the device.
• Necessary maintenance must be performed by qualied service technicians ONLY. Users
are not permitted to maintain the pulse oximeter themselves.
• The oximeter cannot be used together with accessories not specied in User Manual. Only
the accessory that is recommended by Drive Medical can be used with this device.
• This product is calibrated before leaving factory.
1.2 Warning
• Explosive hazard—DO NOT use the oximeter in the environment with ammable material
such as anesthetic.
• DO NOT use the oximeter while the patient is being scanned by MRI or CT.
• The person who is allergic to rubber cannot use this device.
• The disposal the pulse oximeter and its accessories and packing (including battery, plastic
bags, foams and paper boxes) should follow the local laws and regulations.

7
English
• Please check the packing before use to make sure the device and accessories are in accor-
dance with the packing list.
• Please only use accessories and probes approved by Drive Medical, or else it may damage
the device.
• The device can only be matched with the compatible probe.
• Please don’t measure this device with functional tester for the device’s related information.
1.3 Attention
• Keep the oximeter away from dust, vibration, corrosive substances, explosive materials,
high temperature and moisture.
• If the oximeter gets wet, please stop operating it.
• When it is carried from cold environment to warm or humid environment, please do not use
it immediately.
• DO NOT operate keys on front panel with sharp materials.
• High temperature or high pressure steam disinfection of the oximeter is not permitted. Refer
to User Manual in the relative chapter (7.1) for instructions of cleaning and disinfection.
• Do submerge the oximeter in liquid. When it needs cleaning, please wipe its surface with
medical alcohol by soft material. Do not spray any liquid on the device directly.
• When cleaning the device with water, the temperature should be lower than 140° F (60° C).

8English
• Fingers which are too thin or too cold may affect the measurement accuracy. Please clip
the thicker nger, such as thumb and middle nger deeply into the probe.
• The pulse oximeter can be used for adult and pediatric patients, based on the manufacturer
supplied finger probe.
• The update period of data is less than 5 seconds, and is subject to change based on varia-
tions in individual pulse rates.
• Please read the measurements on the waveform screen once the readings have stabilized.
This measure value is most accurate.
• If some abnormal conditions appear on the screen during test process, pull out the patient
finger and reinsert to restore normal use. If continued abnormal conditions appear, contact
your equipment provided.
• The device has a normal life expectancy of three years since the rst electried use.
• This device has alarm functions. Please reference chapter 6.1 for details.
• The device may not work for all patients. If you are unable to achieve stable readings, dis-
continue use.

2 OVERVIEW
The pulse oxygen saturation is the percentage of HbO2in the total Hb in the blood, so-called
the O2concentration in the blood. It is an important bio-parameter for the respiration. A number
of diseases relating to respiratory system may cause the decrease of SpO2in the blood, fur-
thermore, some other causes such as the malfunction of human body’s self-adjustment, dam-
ages during surgery, and the injuries caused by some medical checkup would also lead to the
difficulty of oxygen supply in human body, and the corresponding symptoms would appear as
a consequence, such as vertigo, impotence, vomit etc. Serious symptoms might bring danger
to human’s life. Therefore, prompt information of patients’ SpO2is of great help for the doctor to
discover the potential danger, and is of great importance in the clinical medical field.
The Handy-Ox Pulse Oximeter is a compact, efficient and convenient portable pulse oximeter. It is
only necessary for a patient to put one finger into probe for diagnosis, and the display screen will
directly show the measured value of SpO2and pulse rate with a high level of accuracy.
2.1 Features
A. Operation of the product is simple and convenient.
B. The product is compact, light weight and portable.
C. Low power consumption.
The problem of overrating would emerge when the patient is suffering from toxicosis
which caused by carbon monoxide, the device is not recommended to be used
under this circumstance.

b) Relative humidity: ≤95%
c) Atmospheric pressure: 500hPa~1060hPa
Operating Environment
a) Temperature: 50 ° ~ 104 ° F (10 ° ~40 ° C)
b) Relative Humidity: ≤75%
c) Atmospheric pressure:700hPa~1060hPa
3. PRINCIPLE
Principle of the Oximeter is as follows: An experience formula of data process is established
taking use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reduc-
tive Hemoglobin (Hb) and Oxyhemoglobin (HbO2) in glow & near-infrared zones. Operation
principle of the device is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in
accordance with Capacity Pulse Scanning & Recording Technology, so that two beams of
different wavelength of lights can be focused onto human nail tip through perspective clamp
finger-type sensor. Then measured signal can be obtained by a photosensitive element, infor-
mation acquired through which will be shown on screen through treatment in electronic circuits
and microprocessor.

6 OPERATING GUIDE
6.1 Application Method
A. Measuring the data
a) Open the lid of battery box and put the battery inside, then close.
b) Put the ngertip probe into the jack on the underside of the oximeter. Only use Drive Medical
supplied accessories.
c) Put the nger into the probe.
d) Press and hold the “power on/off button” for a few seconds. The device will power on within a
few seconds and will start to self-check. The device displays the user interface after self-check.
e) Do not shake the nger and keep the patient in a calm state during measurement.
f) The data can be read directly from the screen in the user interface.
Fingernails and the luminescent tube should be at the same side.
If the alarm function is on, the device will provide a medium priority alarm signal when the
probe plug or finger is out. An intermittent alarm will occur and the user interface presents
“FINGER OUT”.
Medium priority indicates that prompt operator response is required.

The corner position of the plug should
be inserted into the right place of the
recessed portion of the socket, just as
shown in the picture.

On the user interface, press the”screen change button” to change the display direction.
C. Pause alarm
a) The Digital Handy-Ox will alarm if the PR or SpO2exceed preset low and high parameters, if
the battery has a low charge, and if the patient’s finger is removed.
b) When alarm is on, press the ”alarm pause button” to pause the alarm. In order to reset the
alarm, press the “alarm pause button” again within 60s.
c) If you want to turn off the alarm for good, enter the menu.
D. Menu operation
In the user interface, press the ”menu button” to enter the menu options screen ((Figure 7).
