DETAILED DESCRIPTION

[0024] Medical masks are often, but not exclusively, used during inhalations or respirations in medical and dental interventions for administering gases to a patient such as anesthetics, nitrous oxide, or oxygen. During the administration of these gases, it is advantageous for the patient if the operator, such as a physician or nurse, monitors the carbon dioxide concentration in the exhaled breath of the patient by means of end-tidal CO.sub.2 measurement (etCO.sub.2 value).

[0025] In this way, a dosing error, the depth of anesthesia or sedation, the respiratory behavior of the patient, such as breathing through the mouth when a nose mask is used, and also incorrect positioning of a mask can be diagnosed. For example, a dosing error would result in flatter respiration of the patient, due to which less carbon dioxide is exhaled, which in turn can be detected and output by means of visual or acoustic warning signals at the mixing system or another directly or indirectly connected analysis device.

[0026] Additionally, thereto, a display screen output can also take place in which one or more waveforms are recognizable on the display, which show a respiratory cycle. In the event of deviation from the normal waveform, the operator or a connected mixing system can automatically readjust the supplied dose. It is typical for oversedation, for example, that the respiratory activity is reduced and carbon dioxide can no longer be exhaled. Real-time monitoring of the patient, in particular with regard to the breathing pattern and the breathing status, can be carried out by the solution according to the invention. Influence can be taken on the given circumstance by suitable regulation and control devices or direct intervention of an operator.

[0027] FIG. 1 shows the system 100 according to the invention with regard to a medical mask as a receptacle container 10 having the apparatus 50 according to the invention. The receptacle container 10 comprises in this case a base body 12, such as an outer mask, and an inner body 14 detachably connectable to the base body 12. The inner body 14 is an inner mask in the embodiment of a medical mask. The base body 12 is used for the predominant purpose of discharging excess fluids, such as the exhaled gas or CO.sub.2 of the patient.

[0028] The inner body 14 comprises at least one valve device 16, which is arranged in the inner body 14 such that when the body of the patient generates CO 2 gas, the valve device 16 opens in order to release escaping CO.sub.2 gas from the inner body 14 of the receptacle container into the base body 12 of the receptacle container 10, wherein the escaping fluid (not shown) escapes therefrom by means of a gas outlet opening 18 of the base body 12.

[0029] The gas supply and gas discharge is ensured in the receptacle container 10 by means of connected flexible tubular formations 20. Moreover, at least one gas source 30 and a mixing system 40 connected by means of at least one line 32 for dosing are provided outside the base body 12, which generally comprise a flow rate regulator 42 and a positive or negative pressure device 44, in order to thus make fluid dosing to and from the inner body 14 and/or base body 12 individually settable.

[0030] Moreover, an apparatus 50 having a proximally located fluid inlet 52 and a distally located first fluid outlet 54, which is directly connected to the fluid inlet 52, and a distally located second fluid outlet 56, which is directly connected to the fluid inlet 52, and which are guided parallel to one another, is provided in the flexible system made of tubular formations 20. A further continuous nitrous oxide line (not shown) is provided instead of the nitrous oxide line 58, 59 in the apparatus 50 for feeding through fluid, in particular the nitrous oxide mixture to the patient.

[0031] In a further embodiment of the apparatus 50, it has a proximally located nitrous oxide outlet 58 and a distally located nitrous oxide inlet 59 arranged offset thereto (cf. FIG. 2) for feeding through the fluid (not shown).

[0032] Furthermore, the mixing system 40 can also comprise a device for analysis 60. The device for analysis 60 is used to evaluate the measurement data of the apparatus 50 which are provided by means of a measuring probe 70 (cf. FIG. 4).

[0033] FIG. 2 shows an apparatus 50, described in more detail hereinafter, for measured value determination, for example of an etCO.sub.2 value, having at least one fluid inlet 52 located proximally to the receptacle container 10 (cf. FIG. 1) and two distally located fluid outlets 54, 56 connected directly to the fluid inlet 52, which are guided parallel to one another. In one particular embodiment, a connecting element, such as the thread 72 shown, is provided as a possible embodiment in the fluid inlet 52 and/or in the fluid outlets 54, 56. Further connecting elements could be, for example, plug-in or press-in systems or screw connections, welds, or again detachable systems such as bayonet fittings.

[0034] The thread 72 in the distally located first fluid outlet 54 is provided for the detachable connection of the measuring probe 70 or a closure 74 if a measuring probe 70 is not desired in the treatment and the access is to be closed.

[0035] In an alternative embodiment, the measuring probe 70 can also be led up to the inner body 14 (cf. FIG. 1), in particular in the example of the medical mask up to the inner mask or up to the nose of the patient. In this way, it is unimportant whether the line of the fluid inlet 52 is gas guiding or gas discharging.

[0036] In FIG. 3, in the transition 80 between proximally arranged fluid inlet 52 and distally located fluid outlets 54, 56, they are spatially opened, so that the fluid flow (not shown) of the fluid inlet 52 is divided into two fluid outlets 54, 56 guided in parallel. It has proven to be particularly advantageous here that the first distally guided fluid outlet 54 has a smaller diameter than the second distally guided fluid outlet 56. Particularly preferably, a ratio of fluid inlet in the range of 2 to 5 to the fluid outlet of 0.5 to 1.5 is particularly advantageous, wherein, for example, a ratio of the cross-sections to one another of fluid inlet to fluid outlet of 1.4:1; 2:1, 5.3:1, or 5:1, in particular 176:127 or 110:21 is particularly preferably used.

[0037] FIG. 4 shows a reversible flexible measuring probe 70 in the at least one distally located fluid outlet 54 as already mentioned above. Plastic hoses or flexible plastic tubes are suitable here as the measuring probe 70, for example. However, depending on the area of application, other measuring probes, such as intelligent or smart systems, for example, having sensor cleaning function, direct data transfer, or the like are also proposed. In one particular embodiment, the flexible measuring probe 70 can extend into the inner body 14 (cf. FIG. 1).

[0038] The measuring probe 70 is preferably designed for etCO.sub.2 value recording and is connected to a device for analyzing 60 the measurement data with the aid of suitable hoses 20. In addition, a slight negative pressure can be provided by the pressure device 44 in order to aspirate the escaping gas of the body or the patient (not shown). Furthermore, the fluid outlet 54 distally guided in parallel to the second fluid outlet 56 is designed to receive a measuring unit 70 such that it can be sealed off using a closure 74. The Luer lock which is widespread in medical technology has proven to be advantageous for this purpose.

[0039] Alternatively, the sample taking can also be carried out without measuring probe 70 through the tubular formation 20 guided in parallel, wherein the inventors have recognized that a higher negative pressure has to be generated for this purpose and a larger dimensioned pressure device 44 has to be provided for this purpose, in order to be able to perform an etCO.sub.2 value determination that can be evaluated. However, depending on the constitution of the patient, an elevated pressure can be perceived as unpleasant.
