staff only.

•The MPR1 may be operated only with the specified mains power adapter, see chapter 11.1 Technical

data.

•Select only such wall outlet for the mains power adapter that is accessible to the user without difficulty.

Do not place the mains power adapter in a way that makes it difficult to disconnect the adapter from

the wall outlet.

•To completely disconnect the MPR1 from the mains, disconnect the mains power adapter from the wall

outlet.

•Prior to using the MPR1, you have to be completely familiar with the operation of the system.

•The MPR1 may be used on one patient at a time only.

•When the apparatus is switched on, a signal is sounded which is intended to check the alarm sounding

unit. If the signal is not sounded, the apparatus must not be used.

•If two or more apparatuses with separate mains connections are used on the same patient, the

apparatus leakage current adds up which may cause a potential hazard. In this case, use shall be

permitted only, if it has been secured that patient and operator are safe, and that the requirements of

standard IEC 60601-1-1 are fulfilled.

•Every person who connects an additional unit to the signal input or signal output configures a medical

system, and thus he / she shall be responsible for the fact that this system meets the requirements of

standard IEC 60601-1-1.

•Simultaneous operation with other apparatuses connected to the patient may cause mutual influences

which may have an effect on the measuring results.

•Note that in the event of different alarm pre-settings for the same or similar devices, which are used in

different hospital areas (e.g. ITS or the operating suite), the interchanging of settings can cause a

potential danger to patients. Therefore always check that the alarm settings are suitable for the patients

concerned prior to starting monitoring. (see chapter 4.3 Alarm limit selection)

•If and when a defibrillator is used, short-time interferences of the signal shapes and values measured

may occur.

•The apparatus can forward up to two invasive pressure signals to a downstream redundant monitoring

system. By means of the downstream system, it is possible to easily integrate the datalogger into a

central monitoring system. In the process special attention has to be given to the fact that only approved

systems from the listed accessories are connected. In case of every signal relaying, proceed as

rendered in the instructions for use of the MPR1: Establish the cable connection; check the signal

transmission; and set the alarm limits to the foreign system.

•Prior to using the MPR1, the correct condition of the apparatus and any accessories shall have to be

checked. Check the plausibility of the readings before using the apparatus for monitoring. The

apparatus and the accessories must not be damaged or soiled; otherwise the apparatus must not be

2 Description of the device

2.1 Intended purpose

2.1.1 Description

The MPR1 is used for monitoring up to three invasively measured physiological pressures and up to two

temperatures of the patient (with alarm function). Devices that were produced until the year 2011 also have

the function of a single-channel ECG with heart rate determination without alarm function. These cabled

applications are covered by the device CE approval in accordance with MDD.

Optionally a single-channel telemetric pressure measurement can be made instead of a measurement via

a cabled pressure measurement channel, provided that the MPR1 has a high enough firmware version

(from firmware version 2.00.00XX, 2.00.00XX HW2, 2.10.00XX respectively 2.10.00XX HW2) and the

necessary accessories (accessories see 3.3.1 General) are available. This telemetric pressure

measurement is solely for ICP measurement using a pressure measurement implant and is covered by the

CE-approval in accordance with AIMDD.

For telemetric use of the MPR1, its use is limited to stationary operation. For all other applications the MPR1

can be used both for stationary patient monitoring as well as for mobile operation in the hospital. After the

vital parameters mentioned have been measured and monitored, the MPR1 ensures a long-time storage

of the values measured.

2.1.2 Intended use

The MPR1 is a diagnostic unit with physiological threshold value monitoring and display of the following

physiological parameters: invasive pressure (IBP and ICP, three channels) and temperature (T, 2

channels). Invasive pressure measurement and temperature measurement are significant performance

characteristics of the unit. These parameters are determined by using RAUMEDIC catheters for single-

channel ICP measurement or with RAUMEDIC multi-parameter catheters for combined measurement of

ICP and temperature. In addition, external transducers may also be used for the invasive pressure

measurement. Optionally up to two pressure signals can be passed on through the two analogue outputs

to a bed-side monitoring device with threshold monitoring.

2.1.3 Operational environment

The MPR1 is intended for use in clinical environments to be operated by specialized medical staff. The unit

is used either stationary or mobile during transport in the hospital. Doctors, intensive care nurses and

medical technicians shall use the unit. The unit is not intended for use outside of the hospitals, such as in

helicopters or in ambulances. The MPR1 is not intended for use in domestic settings.

2.2 Indications

2.2.1 Conditions

The use of the MPR1 is indicated, when the doctor considers it necessary to measure and monitor several

physiological parameters, such as pressure and temperature.

2.2.2 Body parts or types of issue interacting with the unit

MPR1 has no body or tissue contact with the patient. Signals are received from sensors.

2.2.3 Frequency of use

The use of the MPR1 is indicated when the attending physician prescribes the application. The MPR1 has

been designed for continuous operation.

2.2.4 Physiological purpose

The use of the MPR1 is indicated, if the intention is to obtain information for the treatment, to assess the

appropriateness of the treatment, or to exclude the cause of symptoms.
