KaWe Mastermed C, User Manual

7

We recommend K4 for the auscultation of children be-
tween the ages of 3 and 12 years old. K4 is when the 
sound heard with the stethoscope changes from a clear 
sound to a muffled sound. For pregnant patients, we rec-
ommend that K5 be used for auscultation unless the 
heartbeat can be heard when the cuff is deflated, in which 
case K4 should be used. Record both measured values 
rounded up to the next even number (measured in 
mmHg). 

Measure the systolic and diastolic pressure carefully. Re-
peat the measurement if necessary or if there is ever an 
uncertainty or distraction. Do not perform the measure-
ment hastily.  

Cleaning:
Monitor and accessories

 (without cuff): To clean the 

device, first use only a soft dry cloth. The ball, valve and 
tubes are to be wiped clean with a mild detergent and a 
damp cloth. 

Cuff:

 If necessary, wipe the cuff clean with a damp cloth. 

Disinfection:
Cuff: 

The cuff can be wiped clean with a damp cloth and 

soap or disinfectant. The cuffs have been tested for dura-
bility with the following recommended disinfecting 
agents: Buraton (liquid), Cidex, Ethanol 70%, isopropyl 
alcohol 70%, Mikrozid and Sporicidin. 

After being disinfected, the cuff is to be rinsed with clean 
water and air-dried.

 Warnings: 

1.  When the cuff is not connected to the gauge, always 

use a tube stopper to prevent accidental penetration 
of liquid. The penetration of liquid into the tube may 
cause damage to the gauge.

 2.  Periodically inspect and replace damaged or 

deteriorated cuffs.

3.   Use only the appropriate size cuffs. The arterial 

pointer must be in the marked area, otherwise the 
measurement readings may be incorrect.

4.   Do not immerse the device in liquid to clean it.
5.   Do not sterilize the device!
6.   The blood pressure measuring device must be 

handled carefully and must not be exposed to 
pressure, sharp objects or any other mechanical 
stress.

7.   The pointer on the gauge must point within the 

tolerance range of the zero position when there is no 
pressure in the cuff.

8.   Always let all of the pressure out of the cuff before 

storing the instrument.

9.   Protect the surface of the stethoscope diaphragm 

from damage. 

10. Never inflate to more than 300 mmHg.
11.  When replacing or repairing parts, please ensure that 

only original KaWe replacement parts are used.

12.  Make sure that the tube system is airtight.

No changes to the device are allowed!
