Preferably said pressure chamber is provided with at least one pressure relieve opening, provided with a one-way valve, positioned such that fluid can be introduced past the valve into the pressure chamber but not in the opposite direction, wherein prior to use of the device the pressure relief valve is brought into an opened state such that the pressure chamber is in free communication with the environment of the device. The second part and/or the first part are more preferably provided with an electronic circuit for resetting the at least one pressure sensor when said pressure relief valve is in said opened state. This obviates the need of a multi-directional tap or valve. Before use the device can be sterilized with the one way valve in the opened state, having an open communication through the pressure chamber and into the catheter. Upon introduction of the second part into the first part each pressure sensor can be reset. Reset has to be understood as encompassing setting a zero value with reference to the environmental pressure. After setting the one or more sensors the or each one way valve is brought back into an operational position, out of the opened state, such that pressure fluid can not flow from the catheter or pressure chamber to the environment past the valve. In a suitable solution a plug can be used to bring and keep temporarily the valve in the opened state, which can be removed after the setting of the at least one sensor. The setting can be done electronically by a suitable circuit in the first and/or second part.
FIG. 1 shows a measuring device 1 comprising a cassette 2 forming a first part, which is connected to a cassette holder 3 forming a second part. In this application the reference sign 2 will be used for the first part, in any form (e.g. cassette or housing), the reference sign 3 for the second part, in any form (e.g. holder or module) Cassette 2 is provided with measuring means, which in this preferred embodiment are adapted to perform liquid pressure measurements in the field of urology. The measuring means comprises three catheters 4 which are each provided with three ports, i.e. a first port 5 a, 5 b, 5 c for connection of a catheter tube 6 a, 6 b, 6 c (see FIG. 3), a second venting port 7 and a third port 8 in which is arranged a pressure sensor 20 (not shown). The catheters are further provided with a two-way tap 9 and a non-return valve 10. Such a catheter is described at length in the above stated international patent application publication no. WO 02/07595 which is incorporated herein by reference, at least for the catheters.
The second part 3, as shown in FIG. 3, comprises a second connector 28 for connecting to the first connector 27, similar to the connectors as discussed with reference to FIGS. 1-3, for exchange of data and other information and power. In the device 1 as shown in FIGS. 6-11, to only two pressure chambers 18 a catheter is connected, for example by gluing. Shown are a triple lumen catheter 4A with leakage detection 4B and a balloon catheter 4C but obviously any kind of catheter can be connected, based on for example the choice of the manufacturer and/or desires of the user. As shown, the triple lumen catheter has an electrical leakage detector that can be attached to the connecting plate by connecting pins 34. In the relevant two pressure chambers 18 connected to a catheter 4 a one way valve 17 is inserted, for example manufactured by Qosina. The other two pressure chambers are closed off on both sides by suitable lids 29. Into the opening 30 of each valve 17 a plug 31 is inserted, such that the valve is brought and held in an opened position, for sterilization and/or setting, as discussed. The plugs 31 can for example be hollow and can be clamped into the openings 30, such that they can easily be removed before measuring data. It should be noted that such plug or similar means could also be used with a catheter according to WO 02/07595.
The first part 2 further comprises a lid 32, for closing the first part 2. The lid 32 comprises two parts, an upper part 33 which can be secured to he top part 21 at the side of the end wall 22. A lower part 35 can be slid in and over the bottom part 33, having an end wall 36 such that the lid 32 will close of the housing or first part 2 around a second part 3 connected to the connecting plate 26. In the lid 32 an opening 37 can be provided in which a sensor or other attachment means can be provided for connecting the first part to means for wearing the device, for example on an arm, leg, garment or the like, as discussed with respect to the embodiment according to FIGS. 1-3. Once the lid is positioned, the first part is hermetically closed and shields a second part 3 positioned therein from the environment and vice versa.
FIG. 7 shows the assembled device 1 of FIG. 6, from the bottom, FIG. 8 from the top.
A device 1 according to FIG. 6 can be made manufacturing the bottom part 21, for example by injection molding, including the hollow pressure chambers 18, after which the sensors 20 are positioned over the openings 19, for example by gluing. Then the connecting board 23, the interconnectors 24 and the connecting plate are brought into position. Suitable snap means 50 are provided for locking these into position, as shown in FIG. 9.
The lid 32 will be placed, as is shown in FIG. 10, together with the valves 17 with plugs 31 and lids 29. The first part 2, comprising the catheters will then normally be sterilized, wrapped in a wrapper and send to the user, ready for application.
As discussed before, upon connecting the connectors 27, 28, a timer is set in the chip 13, timing a period in which the device can be used or during which at least the measurement of data has to commence. Would the second part be removed again within a certain time after said connecting, it may be reloaded but after the time, which is preferably considerably shorter then the period, reconnecting will be useless because the chip 13 will prevent reuse. The first part is a disposable, to be used only once.
