1.3        Security symbol

1.4        Safety warning information

In order to ensure the safety of the patient and the operator, the following safety rules should be strictly observed in the use of the wireless ultrasonic probe.

 

WARNING:	1.	Do not disassemble the ultrasonic probe, which may cause electric shock.
	2.	Use the power cord supplied with this unit; use only the power supply provided by the company to supply power, the use of other specific power supply (such as UPS, etc.) on the ultrasonic probe power supply may bring the risk of electric shock.
	3.	Use the probe carefully, if the probe is scratched with the contact surface of the human body, immediately stop using the probe and contact the service representative. If you use a scratched probe, there is a risk of electric shock
	4.	Every time you use the instrument must be checked for safety, do not let the probe by the impact of damaged ultrasound probe may cause the patient to be shocked.
	5.	Before performing an ultrasound check, check the surroundings to ensure safe use within the environment. Do not operate the unit in an environment with flammable or explosive liquids, vapors or gases such as oxygen or hydrogen.
	6.	Be sure to wear a sterile probe case on the probe when performing an ultrasonic chamber check.
	7.	Do not immerse the ultrasonic probe Type-C interface or above in water or disinfectant. Because the Type-C interface of the ultrasonic probe does not have a waterproof function, this may cause an electric shock or a probe malfunction.
	8	Before and after each inspection, you must ensure that the ultrasound sound normal. A defective ultrasonic probe may cause the patient to be shocked.
	9	Please select the correct type of probe head according to the different parts of the inspection. Do not use any probe provided by our company. Otherwise, it will damage the machine and the probe.
	10	In order to ensure safety, the charging of the system can only be carried out in the state of shutdown, and the charging is not allowed under the power-on state.

 

CAREFUL：	1.	Matters needing attention in clinical examination technology： This equipment can only be operated by qualified medical personnel. This manual does not introduce a clinical examination technique. It is necessary to select the correct inspection techniques according to the professional training knowledge and clinical experience.
	2.	The equipment can not be checked for a long time.
	3.	Please follow the ALARA principle during ultrasonic diagnosis, especially in the examination of pregnant women, fetuses and newborns. The sound power can be reduced as much as possible when satisfactory clinical diagnostic maps can be obtained.
	4.	If the APP software fails during installation or use, please promptly provide feedback to the after-sales maintenance personnel to avoid misdiagnosis.
	5.	The APP software will be upgraded from time to time, and new updates will be submitted by the developer. If you want a better experience, please pay attention to download and upgrade.
	6.	Do not use incompatible coupling agents, disinfectants, probe protective cover, probe, puncture rack.
	7.	Sterile gloves must be worn to prevent infection when using ultrasonic probes.
	8.	You must use a sterile ultrasound coupling agent. Use a coupling agent that is in compliance with local regulatory requirements. In addition, it is necessary to properly manage and use the ultrasonic coupling agent to ensure that it does not become a source of infection.
	9.	Normal ultrasound does not cause burns at room temperature; however, if the probe is placed in the same position for a long time, the patient may be burned.
	10.	The probe cover is made of natural rubber and is used with caution for natural rubber allergy.
	11.	For in vivo transducers in a single fault condition, the surface temperature rise shall not exceed 43 ° C.

 

 

CAUTION ：	1	In order to prevent abnormal probe function, read the following safety precautions: After each ultrasonic examination, the ultrasonic coupling agent on the surface of the probe should be thoroughly erased. Otherwise, the ultrasonic coupling agent will be solidified on the probe head, which will affect the quality of the ultrasound image. The probe should be cleaned and disinfected before and after each ultrasonic examination。
	2	Ambient environmental requirements: Please use the ultrasonic probe in the specified environment： ambient temperature：0℃～ 32℃ relative humidity：30% ～ 85%（No condensation） Atmospheric pressure：70KPa ～ 106KPa。 To prevent damage to the ultrasonic probe, do not expose the probe to the following environment： Place where the sun shines A place where the temperature changes dramatically. A place filled with dust Easy to vibrate place Place near the heat source
	3	Repeated disinfection will lead to the safety and performance of the probe, the performance of the probe should be regularly checked.
