### Claim 4 (depends on 1)

The method according to claim 1, further comprising storing information in a table about a presence of the connection.

### Claim 5 (depends on 4)

The method according to claim 4, wherein the table comprises rows and the columns each representing one of the first channel and the at least one second channel.

### Claim 6 (depends on 1)

The method according to claim 1, wherein, during the applying, one or more of compressed air and a liquid is pumped into the first channel to build up the testing pressure.

### Claim 7 (depends on 1)

The method according to claim 1, wherein, the applying comprises, applying the first testing pressure is applied into a first medical device as the first channel.

### Claim 8 (depends on 7)

The method according to claim 7, wherein, of the receiving comprises, receiving a pressure in a second medical device as the second channel.

### Claim 9 (depends on 1)

The method according to claim 1, wherein, the applying comprises, applying the first testing pressure to the first channel and the at least one second channel using a 3/2-way valve.

### Claim 10 (depends on 1)

The method according to claim 1, wherein, the applying comprises, applying the first testing pressure to the first channel and the at least one second channel by a pressure connection of a pulsation module and wherein, the receiving comprises, receiving the first pressure signal by a pressure sensor of the pulsation module.

### Claim 11 (depends on 10)

The method according to claim 10, wherein the pressure sensor and the pressure connection are arranged in a common pulsation module housing.

### Claim 12 (depends on 1)

He method according to claim 1, wherein one or more of the applying, receiving and detecting are executed whether a recirculation pump for recirculating a treatment liquor is switched on or switched off.

### Claim 13 (depends on 1)

The method according to claim 1, further comprising conducting a treatment liquor through one or more of the first channel and the second channel in response to the detected connection.
