DETAILED DESCRIPTION

[0053] A test disk 1 is illustrated in FIG. 1. The test disk 1 has a base body 2, on the front side of which there are arranged an on/off switch 3, a start/stop pushbutton 4, a filling valve 5 for filling a glove volume, a pre-filter 6 and an LCD display 7. The test disk 1 has a first sealing device 8, which surrounds the oval base body 2 radially and circumferentially. By inflating the hose-like first sealing device 8, the latter expands outward in a direction which is symbolized by arrows.

[0054] FIG. 1 therefore illustrates a test disk 1 which can be inserted into an aperture forming the port and has the effect of sealing from inside to outside. Arranged within the base body of the test disk are electronic components such as a pressure sensor for detecting a pressure in the glove volume, a pressure measuring device having a microprocessor and a pressure sensor for detecting the pressure in the sealing device. Also provided is a valve for filling the sealing device via a first pump. A second pump serves to fill the glove volume. As a reading device for reading identification elements of the glove and of the port, use is made of an RFID module, wherein an interface with a Wi-Fi module is provided for data transmission to an evaluation unit. An energy source serves to supply energy to the individual components.

[0055] In FIG. 2 the test disk 1 with base body 2 and circumferential first sealing device 8, together with an inductive charging station 9, is illustrated in a sectioned side view. Arranged in the base body 2 is an accumulator 10, being a rear side 11 of the base body 2 is completely closed. The accumulator 10 is therefore arranged in a fully protected manner within the base body 2, which is closed in a fluid-tight manner.

[0056] Via the charging station 9, the accumulator 10 can be charged without contact, that is to say without producing a line-bound connection. For this purpose, the test disk must merely be arranged over an appropriate inductive charging device 12 of the charging station 9. In the simplest case, the test disk 1 is simply deposited there. The charging station 9 has a connecting cable 13, via which electrical energy can be supplied, for example from a public supply network.

[0057] FIG. 3 illustrates an alternative refinement of the base body 2, in which the accumulator 10 is accommodated in a compartment 13 in the base body 2 which can be closed in a fluid-tight manner via a cover 14. The cover ends in particular flush with the rear side 11. The charging station 9 is unchanged.

[0058] FIG. 4 shows a test system comprising a base body 2 and a sealing adapter 18, which can be connected to each other via coupling means 19, which are formed as a bayonet fastener. The circumferential, radially expandable sealing device 8 is arranged on the sealing adapter 18. The test disk is therefore formed by the combination of base body 2 and sealing adapter 18. By means of appropriate selection of the sealing adapter, this test system can thus be inserted into different ports using the same base body 2.

[0059] FIG. 5 shows an alternative refinement of the sealing adapter 18 as compared with FIG. 4. Here, the first sealing device 8 is arranged on an inner side of a cylindrical extension 19 of the sealing adapter 18, so that a port can be overlapped. Following expansion of the sealing device 8, by which means the latter stretches radially inward, sealing from outside to inside takes place. Otherwise, this refinement corresponds to the previous refinement.

[0060] FIG. 6 illustrates a test system comprising a test disk 1 with base body 2 and first sealing device 8 and also a sealing body 15 having a second sealing device 16 in a sectioned side view.

[0061] In order to be able to insert the test disk 1 in a fluid-tight manner into ports having another opening, the replaceable sealing body 15 is provided. For this purpose, the base body 2 is inserted, in particular flush, into a corresponding recess 17 of the selected sealing body 15. By expanding the first sealing device 8, secure fixing of the base body with the electronic components within the sealing body 15 is then carried out. These can then be inserted together into a corresponding port, whereupon the second sealing device 16 is expanded, so that the test disk is held reliably and in a fluid-tight manner in the port.

[0062] The recess 17 in this refinement is formed with a bottom. Accordingly, an application of pressure to the glove volume is carried out through corresponding pressure lines formed in the sealing body or through openings, not shown, in the bottom of the recess 17.

[0063] FIG. 7 shows an alternative refinement in which, differing from the refinement according to FIG. 6, the base body is not provided with a circumferential sealing device. As a result, the base body itself cannot be used as a test disk but only in connection with a corresponding sealing body. If necessary, sealing of the base body in the recess can be carried out via appropriate sealing elements, so that the underside of the base body can enter into pressure-conducting contact with the glove volume without it being necessary to fear any pressure loss.

[0064] The invention is not restricted to one of the above-described embodiments but can be modified in multifarious ways.

[0065] Thus, in particular, the arrangement of the sealing device in the example in FIGS. 1 to 3 and 6 and 7 can also be configured in a manner analogous to the refinement according to FIG. 5, so that an overlapping of the ports and sealing from the outside to inside is carried out. In addition, if necessary, an additional pump can be arranged in the sealing adapter or in the sealing body in order to expand the respective pressure device and/or to pressurize the glove volume. However, it is also conceivable to use a pump arranged in the base body for this purpose.

[0066] All the features and advantages emerging from the claims, the description and the drawing, including constructional details, physical arrangements and method steps, can contribute to the invention, both on their own and in the widest possible range of combinations.
