## Background
RELATED APPLICATION DATA
This application claims priority to and the benefit of Danish Patent Application No. PA 2014 70305, filed May 28, 2014, pending, and European Patent Application No. 14170297.7, filed on May 28, 2014, pending. The entire disclosures of both of the above applications are expressly incorporated by reference herein.
FIELD
The present disclosure relates to an audiologic test apparatus. In particular, the present disclosure relates to an audiologic test apparatus used to perform different audiologic tests, such as acoustic reflex, acoustic reflex threshold, tympanometric and/or otoacoustic emission tests.
BACKGROUND
In order to perform an audiologic test, such as an acoustic reflex test, acoustic reflex threshold test, tympanometric test and/or otoacoustic emission tests, a probe needs to be positioned in the ear canal. However, specific audiologic tests may require different probes, or have different requirements to the probe. For example, a screening type acoustic reflex test may be performed with a hand-held probe, whereas a diagnostic type acoustic reflex test (also known as an acoustic reflex threshold test) may require a probe fitted and retained in the ear of a user.
Furthermore, it may be desirable that the probe is as simple as possible in order to perform the test as convenient and easy as possible. Thus, a probe fulfilling the technical requirements of all audiologic tests may be undesirable to use in some audiologic tests, e.g. due to timely and/or uneasy fitting. For example, a probe being fitted and retained in the ear of the user may be used for both screening type and diagnostic type acoustic reflex tests, but due to easiness of using a hand-held probe and the fact that most acoustic reflex tests are screening type acoustic reflex tests it is desirable to have a hand-held probe.
SUMMARY
Previously, the problem may have been addressed, either by having a plurality of apparatuses, e.g. one for each audiologic test, or employing a configurable probe, which in one configuration was suitable for one audiologic test and in another configuration suitable for another audiologic test. However, having a plurality of apparatuses is both expensive and takes up excess space, and a configurable probe is inherently in need of configuration, thus being inappropriately time consuming.
Hence, despite the known solutions there is a need for an audiologic test apparatus that provides for easy performance of different audiologic tests, wherein the audiologic tests have different requirements to the probe, e.g. screening type and diagnostic type acoustic reflex tests.
Accordingly, an audiologic test apparatus is provided. The audiologic test apparatus comprises: a processing unit, a first probe connector, a second probe connector, and a pump module. The processing unit is configured to conduct a set of audiologic tests including a first audiologic test and a second audiologic test.

The second probe connector is for connecting a second probe for the second audiologic test. The second probe connector is connected to the processing unit and comprises a second fluid port. The pump module is connected to the first fluid port with a first fluid channel and the second fluid port with a second fluid channel. The pump module in a first operating mode is configured to be in fluid communication with the first fluid port, and in a second operating mode is configured to be in fluid communication with the second fluid port. The pump module is configured to modify pressure in the first fluid channel when conducting the first audiologic test in the first operating mode, and the pump module is configured to modify pressure in the second fluid channel when conducting the second audiologic test in the second operating mode.

The pump module is configured to modify pressure in the first fluid channel when conducting the first audiologic test in the first operating mode, and to modify pressure in the second fluid channel when conducting the second audiologic test in the second operating mode.
Also disclosed is a method for operating an audiologic test system such as the audiologic test system, and/or an audiologic test apparatus such as the audiologic test apparatus, configured to conduct a set of audiologic tests including a first audiologic test and a second audiologic test.

FIG. 7 shows a flow diagram of an exemplary method 100 for operating an audiologic test system, e.g. an audiologic test system 2, 2′ as described in relation to any of the previous figures.
The method 100 comprises: connecting 102 a first probe 10 to a first probe connector 8, connecting 104 a second probe 14 to a second probe connector 12, selecting 106 an audiologic test, configuring 108 the pump module 16, 16′, and optionally initiating 110 the audiologic test.
One or both steps of connecting 102 the first probe 10, and/or connecting 104 the second probe 14, may be omitted. For example, connecting 102 the first probe and/or connecting 104 the second probe are omitted if the audiologic test apparatus 4′ and the first and/or second probes 10, 14 are not disconnectable, e.g. as illustrated in the example of FIG. 1. In another exemplary method (not illustrated), the steps of connecting 102 the first probe 10 and connecting 104 the second probe 14, are interchanged.
Selecting 106 an audiologic test may comprise selecting an audiologic test of a plurality of audiologic tests or a set of audiologic tests. For example, selecting 106 may comprise selecting an audiologic test of the first audiologic test and the second audiologic test. The first audiologic test may be a screening type acoustic reflex test. The second audiologic test may be a diagnostic type acoustic reflex test. In an embodiment, the audiologic test selection 106 may be performed automatically by the audiologic test system 2,2′ e.g. based on detection of a probe selected from a probe holder.
Configuring 108 the pump module 16, 16′ comprises configuring the pump module 16, 16′ to be in fluid communication with the first fluid port 24 if the selected audiologic test is the first audiologic test, and configuring 108 the pump module 16, 16′ comprises configuring the pump module 16, 16′ to be in fluid communication with the second fluid port 26 if the selected audiologic test is the second audiologic test.
For example, selecting 106 an audiologic test is selected to be a diagnostic type acoustic reflex test, wherein the selection 106 was a selection between a screening type acoustic reflex test and a diagnostic type acoustic reflex test. The selection 106 may be performed in various ways, e.g. via a user interface, such as a touch screen, a designated button/selector switch, and/or using a method for detecting whether the first or second probe has been selected.
The method 100 comprises the step of initiating 110 the audiologic test selected, after configuring 108 the pump module 16, 16′ according to the audiologic test selected.

The specification and drawings are, accordingly, to be regarded in an illustrative rather than restrictive sense. The claimed inventions are intended to cover alternatives, modifications, and equivalents.
