Description

[Technical Field]

[0001] The present invention relates to a device for providing a hypoxic gas mixture, the device comprising a gas reservoir, a gas delivery device, a supply line suitably designed to pass the gas mixture from the gas reservoir to the gas delivery device and / or a discharge line suitably designed to pass the gas mixture from the gas delivery device to the gas reservoir, and a CO2 absorber disposed within a carrier element. The present invention also relates to a method for performing hypoxic training, the method comprising the steps of inserting a container into the carrier element of the device for providing a hypoxic gas mixture, the container including a CO2 absorber, and connecting the gas delivery device to a user's mouth and / or nose. The present invention also relates to a container with a CO2 absorber for performing hypoxic training, the container being hermetically sealed. [Background technology]

[0002] Hypoxia triggers a response in every cell in the body, allowing for increased energy metabolism. It can contribute to the activation of various genes. Athletes, healthy people, and sick people can all benefit from hypoxia.

[0003] The beneficial effects of high-altitude training have long been known. However, until a few years ago, it was not fully explained how a slight oxygen deprivation could lead to improved physical performance. The observed increase in red blood cells was not sufficient to explain the changes occurring within the body. A breakthrough in understanding came with the discovery of the hypoxia-inducible factor HIF-1α, which helped explain the comprehensive effects of high-altitude training. The abbreviation HIF stands for hypoxia-inducible factor. The reason for this terminology is that it is an oxygen sensor that is activated when oxygen is deficient within the body's cells. The oxygen sensor controls one of the most important processes in the body for survival: the adaptation of cells, tissues, and organs to oxygen deprivation. At the same time, it also signals the body to repair itself.

[0004] The best-known beneficial effect of HIF is the synthesis of erythropoietin (EPO) in the kidney and liver. Prior to its discovery, HIF played a role in explaining changes in the cardiovascular, respiratory, and hematologic systems. It is now clear that the performance improvements are more comprehensive. Endothelial cells in the intima respond to hypoxia with increased synthesis of nitric oxide (NO). This gas plays a crucial role in vasodilation. NO leaves the endothelium and exerts a relaxing effect on smooth muscle cells in the surrounding tissue. Within the intima-media layer itself, NO prevents platelet adhesion and aggregation. In this context, it is also interesting to note that endothelial cells produce the angiogenic factor VEGF under hypoxic conditions. This formation results in the formation of new capillaries in the context of hypoxic therapy. These new vessels are frequently present in damaged tissue or in areas with poor blood flow.

[0005] All known devices for performing hypoxic training have at least one respiratory reservoir into which a certain amount of ambient air is introduced at the beginning of each diagnostic, training, or therapy session. When a user connected to this reservoir inhales and exhales from the reservoir, the oxygen in the reservoir is consumed, producing an oxygen-deficient, oxygen-containing gas mixture in the reservoir. This mixture is purified from excess carbon dioxide, and the remaining oxygen is measured at least periodically during each session.

[0006] Patent document 1 presents a breathing apparatus for using a low-oxygen mixed gas, which comprises a support frame, a breathing reservoir with an inhalation valve, a first sensor for the oxygen content, and an absorber for CO2 and HO, a controllable compressor connected to the breathing reservoir via a puff valve, a chamber for sampling and accumulating a partial sample of the mixed gas, with a second sensor for the oxygen content, a controllable regulating valve, and a controllable ejector, a user attachment, an inhalation line with a controllable center valve and a first flow meter for measuring the inhalation speed, a main exhalation line with a T-fitting and a first air blower connecting the attachment to the reservoir, an additional exhalation line with a second flow meter for measuring the sample aliquot volume and a second air blower connecting the connection to the chamber, an additional sensor complex, and a control unit.

[0007] The device presented here is very complex in design and therefore very expensive to purchase. Its use is particularly complex for individual users and therefore must be carried out under the supervision of a specialist. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] International Publication No. 2012 / 005712 Summary of the Invention [Problem to be solved by the invention]

[0009] It is therefore an object of the present invention to provide a device for providing a hypoxic gas mixture that enables hypoxic training for individual users in an efficient, cost-effective, and safe manner, even without professional supervision.

[0010] It is therefore a further object of the present invention to provide a method for performing hypoxic training that allows for the safe and at the same time efficient implementation of hypoxic training for individual users, even without professional supervision.

[0011] It is also an object of the present invention to provide a container with a CO2 absorber for performing hypoxic training, which allows for the safe and at the same time efficient performance of hypoxic training for individual users, even without the supervision of a specialist.

[0012] It is therefore an object of the present invention to provide a device that provides a hypoxic gas mixture that enables hypoxic training for individual users in an efficient, cost-effective, and safe manner, even without medical supervision.

[0013] Furthermore, it is an object of the present invention to provide a method for implementing hypoxic training, which method allows for the safe and at the same time efficient implementation of hypoxic training for individual users, even without medical supervision.

[0014] It is also an object of the present invention to provide a container with a CO2 absorber for performing hypoxic training, which allows for safe and at the same time efficient hypoxic training for individual users, even without medical supervision. [Means for solving the problem]

[0015] The above object is achieved by a device for providing a low-oxygen gas mixture according to claim 1. Further advantageous configurations of the invention are described in the dependent claims.

[0016] The device for providing a hypoxic mixed gas according to the present invention includes a gas reservoir. The gas reservoir is an air reservoir containing a mixed gas for performing hypoxic therapy and / or hypoxic training. The device for providing a hypoxic mixed gas further includes a gas delivery device. The gas delivery device is typically embodied as a breathing mask that a user wears over their breathing openings (mouth and nose) to perform hypoxic therapy and / or hypoxic training. The device for providing a hypoxic mixed gas further includes a supply line suitably designed to pass the mixed gas from the gas reservoir to the gas delivery device and / or a discharge line suitably designed to pass the mixed gas from the gas delivery device to the gas reservoir. The supply line and / or discharge line are typically embodied as flexible hoses that gas-tightly connect the gas delivery device to the gas reservoir. The device for providing a hypoxic mixed gas further includes a carrier element in which a CO2 absorber according to the present invention can be disposed.

[0017] In a refinement of the invention, the CO2 absorber can be arranged in a carrier element and removed therefrom. Optionally, the carrier element is suitably designed to accommodate the CO2 absorber as a so-called disposable.

[0018] Disposables in the sense of the present invention refer to packaged units of CO2 absorbers, preferably with a fixed CO2 absorber content. The CO2 absorbers can be packaged in a container or in loose form, for example. In the packaged form, the disposables have an outer shape determined by the carrier element of the device for providing a hypoxic gas mixture.

[0019] The device of the present invention is a so-called pendulum rebreather, which means that the same air is repeatedly inhaled and exhaled. Therefore, carbon dioxide, which accumulates in the air, must be removed from the breathing circuit. Normal breathing air contains 21% oxygen. With each breath, approximately 4% of the oxygen is removed from the inhaled air and replaced by an equivalent amount of carbon dioxide (CO2) exhaled. In principle, a given volume of air can be "breathed" several times before the oxygen runs out, but exhaled carbon dioxide accumulates in the air. Furthermore, too much carbon dioxide in the inhaled air poses physiological risks. A concentration of 5% or more can lead to loss of consciousness, and a prolonged concentration of 8% or more can lead to death.

[0020] In this regard, the device of the present invention includes a carrier element in which a CO2 absorber is disposed. The CO2 absorber is consumed during hypoxic treatment and / or hypoxic training and typically needs to be replaced before or after each hypoxic treatment and / or training, or after consumption. The carrier element contains the CO2 absorber and is disposed within the breathing circuit of the device of the present invention. The CO2 absorber is typically a solid mixture of calcium hydroxide and sodium hydroxide (so-called soda lime). During hypoxic treatment and / or hypoxic training, air flows through the soda lime, where carbon dioxide first combines with the sodium hydroxide and is then regenerated by the calcium hydroxide, also known as slaked lime, contained therein.

[0021] In a refinement of the invention, the CO2 absorber is arranged in a container, which is arranged in a carrier element, the container holding the powdered CO2 absorber, the container being embodied as a replaceable cartridge that can be replaced with an unused cartridge before or after hypoxic therapy and / or hypoxic training.

[0022] In a further configuration of the invention, the carrier element has an opening through which the container can be inserted into the carrier element, which opening allows the container to be exchanged before or after hypoxic therapy and / or hypoxic training.

[0023] In a further embodiment of the invention, the carrier element can be closed, and the opening for exchanging the container can be closed, in particular can be reopened.

[0024] In a refinement of the invention, the carrier element has a body and a flap, with which the carrier element can be closed, the flap being arranged movably relative to the carrier element for opening and closing the carrier element.

[0025] In a further configuration of the invention, a seal is arranged between the flap and the body of the carrier element, the seal being suitable for hermetically closing the carrier element with the flap, so that the CO2 absorber arranged in the container absorbs only carbon dioxide from the user's breathing air and is not contaminated by carbon dioxide from the ambient air.

[0026] In a further configuration of the invention, the container can be connected to a supply line and / or a discharge line so that a gas mixture for performing hypoxic therapy and / or hypoxic training is passed through the container, whereby a CO2 absorber disposed within the container ensures removal of carbon dioxide from the gas mixture.

[0027] In a further aspect of the invention, a seal is disposed between the container and the supply line and / or the exhaust line, which seal prevents the mixed gas from leaking from the container and the supply line and / or the exhaust line, and thus a CO2 absorber disposed within the container absorbs only carbon dioxide from the user's breathing air and is not contaminated by carbon dioxide from the ambient air.

[0028] In a further configuration of the invention, the container is placed in the supply line and / or discharge line such that the mixed gas is forced through the container, thus exposing the container and the CO2 absorber placed therein to the user's breathing air, and effectively absorbing carbon dioxide in the mixed gas.

[0029] In a further embodiment of the invention, the device has a supply line and an exhaust line. Separate supply and exhaust lines ensure that the user only inhales carbon dioxide-free air, making the device according to the invention particularly safe to use.

[0030] The above object is further achieved by a method for performing hypoxic training as defined in claim 11. Further advantageous configurations of the invention are also defined in the dependent claims.

[0031] The method for performing hypoxic training according to the present invention comprises two method steps: In a first method step, a CO2 absorber is inserted into a carrier element of a device for providing a hypoxic gas mixture, the carrier element being arranged in the breathing circuit of the device for providing a hypoxic gas mixture and adapted to receive the CO2 absorber.

[0032] In a second step, a gas delivery device is connected to the user's mouth and / or nose. The gas delivery device is typically embodied as a breathing mask that the user wears over their breathing orifices (mouth and nose) during hypoxic therapy and / or training. This ensures that the user only breathes the hypoxic gas mixture provided by the hypoxic gas mixture providing device and delivered to the breathing circuit.

[0033] In a refinement of the invention, the CO2 absorber is arranged in a container, which is arranged in a carrier element, the container holding the powdered CO2 absorber, the container being embodied as a replaceable cartridge that is replaced with an unused cartridge before or after hypoxic therapy and / or hypoxic training.

[0034] In a further configuration of the present invention, the container is connected to a supply line and / or a discharge line of a device for providing a hypoxic gas mixture. The supply line is suitably designed to pass the gas mixture from a gas reservoir to a gas delivery device. The discharge line is suitably designed to pass the gas mixture from the gas delivery device to the gas reservoir. The supply line and / or the discharge line are typically embodied as flexible hoses and gas-tightly connect the gas delivery device to the gas reservoir. The container is connected to the supply line and / or the discharge line so that the gas mixture passes through the container to perform hypoxic therapy and / or hypoxic training. This ensures that a CO2 absorber arranged in the container removes carbon dioxide from the gas mixture.

[0035] In a further embodiment of the present invention, when connecting a container to the supply line and / or discharge line of the device for providing a hypoxic mixed gas, an airtight connection is established between the container and the supply line and / or discharge line, thereby preventing leakage of the mixed gas from the container and the supply line and / or discharge line. Thus, a CO2 absorber disposed in the container absorbs only carbon dioxide from the user's breathing air and is not contaminated by carbon dioxide from the ambient air.

[0036] In a further design of the invention, the container is hermetically sealed when inserted into a device for providing a hypoxic gas mixture. When in a delivery state, the container is sealed so that a CO2 absorber disposed within the container does not absorb CO2 from the ambient air and is therefore not consumed before being inserted into the device for providing a hypoxic gas mixture.

[0037] In a refinement of the invention, the container is opened in a first position. In a further aspect of the invention, the container is opened in a second position. In a further configuration of the invention, the first and second positions are located opposite each other on the container. Opening the container opens an opening through which the mixed gas flows to perform hypoxic training.

[0038] In a further configuration of the invention, the container connects a first section of the supply line and / or the discharge line to a second section of the supply line and / or the discharge line. In a further embodiment of the invention, the first and / or second locations are connected to the connections of the first and / or second sections of the supply line and / or the discharge line. Thus, the container is disposed in the supply line and / or the discharge line, and thus the CO2 absorber disposed in the container absorbs only carbon dioxide from the user's breathing air and is not contaminated by carbon dioxide from the ambient air.

[0039] Furthermore, the above-mentioned object is achieved by a container provided with a CO2 absorber for performing hypoxic training as set forth in claim 22.

[0040] According to the present invention, a container with a CO2 absorber for performing hypoxic training is sealed. In particular, in a delivery state, the container is airtightly sealed. When in the delivery state, the container is sealed so that the CO2 absorber disposed in the container does not absorb CO2 from the ambient air and is therefore not consumed before being inserted into a device that provides a hypoxic gas mixture.

[0041] In a refinement of the invention, the container has one or more opening areas, which are designed to allow the container to be opened at the opening areas. In a further embodiment of the invention, the opening areas have openings. Opening the container opens openings arranged in the opening areas through which the mixed gas flows to perform hypoxic training. The container is embodied to be airtight against the ambient air.

[0042] In a further configuration of the invention, the opening is hermetically sealed when in the delivery state, such that a CO2 absorber disposed within the container does not absorb CO2 from the ambient air and is therefore not consumed prior to insertion into a device for providing a hypoxic gas mixture.

[0043] In a further embodiment of the invention, the opening area of ​​the container has a sealing surface. In a further development, the sealing surface has a seal that prevents the gas mixture for performing hypoxic training from leaking out of the container and the supply and / or discharge lines, while at the same time preventing a CO2 absorber arranged in the container from being contaminated by carbon dioxide from the ambient air.

[0044] Exemplary embodiments of the inventive device for providing a hypoxic gas mixture, the inventive method for performing hypoxic training, and the inventive container with a CO2 absorber for performing hypoxic training are shown in simplified schematic form in the drawings and are explained in more detail in the following description.

[Figure 5b] FIG. 2 is another view of the sealed container. DETAILED DESCRIPTION OF THE INVENTION

[0046] FIG. 1 illustrates a device 1 for performing hypoxic therapy and / or hypoxic training. The device 1 includes a gas delivery device 20, which is embodied as a respiratory mask and is worn by a user P over the respiratory openings (mouth and nose) during hypoxic therapy and / or hypoxic training. The device 1 also includes a gas reservoir 10. The gas reservoir 10 and the gas delivery device 20 are gas-tightly connected to each other via a flexible gas line 30. The gas line 30 includes a carrier element 100 for receiving a CO2 absorber A. In all exemplary embodiments shown herein, the CO2 absorber A is a mixture of calcium hydroxide (Ca(OH)2) and sodium hydroxide (NaOH), also known as soda lime. The carrier element 100 is disposed in the gas line 30 so that the mixed gas passes through the carrier element 100 during hypoxic therapy and / or hypoxic training. The carrier element 100 includes a body 110 and an opening 120. The opening 120 can be opened and closed by a flap 130.

[0047] A preferred embodiment of a device 1 according to the present invention for performing hypoxic therapy and / or hypoxic training is shown in Figure 2. The device 1 also comprises a gas delivery device 20. The gas delivery device 20 is connected to the gas reservoir 10 via a flexible supply line 40 and an equally flexible exhaust line 50. The supply line 40 and the exhaust line 50 each comprise a one-way valve V. The one-way valve V ensures that the user P only inhales air from the supply line 40, thereby preventing the user P from inhaling CO2-laden air from the exhaust line 50 when inhaling.

[0048] In this exemplary embodiment, the discharge line 50 comprises a carrier element 100 for receiving the CO2 absorber A. The carrier element 100 comprises a body 110 and an opening 120 which can be opened and closed in an airtight manner by a flap 130. The flap 130 has a suitable seal 140 for this purpose. The discharge line 50 comprises a first section 51 and a second section 52 which are airtightly connected to each other by the carrier element 100.

[0049] The CO2 absorber A is placed in the container 200 (see Figures 4 and 5). To perform hypoxic therapy and / or hypoxic training, the container 200 is inserted into the carrier element 100 with the flap 130 open before the start of hypoxic therapy and / or hypoxic training. The carrier element 100 is airtightly closed by the flap 130, and the gas delivery device 20 (respiratory mask) is airtightly connected to the mouth and nose of the user P.

[0050] The actual hypoxic treatment and / or training then begins, with the user P repeatedly inhaling and exhaling the same air. The CO2 absorber A prevents asphyxiation. For this purpose, the device 1 has a measuring device that permanently monitors the health status of the user P during the hypoxic treatment and / or training. In particular, a pulse oximeter is used to monitor the heart rate and the oxygen content in the blood. The measuring device is connected to a control unit that issues an alarm signal in the event of a complication, for example a drop in the oxygen level in the user's blood, so that the hypoxic treatment and / or training is immediately stopped.

[0051] 3 shows a further exemplary embodiment of a device 1 according to the present invention for performing hypoxic therapy and / or hypoxic training. The device 1 also comprises a gas delivery device 20. The gas delivery device 20 is connected to the gas reservoir 10 via a flexible supply line 40 and a similarly flexible exhaust line 50. The supply line 40 and the exhaust line 50 each comprise a one-way valve V. In this exemplary embodiment, a carrier element 100 having a body 110, a flap 130 and an opening 120 is arranged on the supply line 40, and a first section 41 of the supply line 40 and a second section 42 of the supply line 40 are each gas-tightly connected to the carrier element 100.

[0052] In this exemplary embodiment, the CO2 absorber A is not disposed within the container 200, but is disposed as powder granules within the carrier element 100 so that breathable air is forced through the CO2 absorber A when performing hypoxic therapy and / or hypoxic training.

[0053] An exemplary embodiment of a carrier element 100 with a container 200 in a delivered state is shown in Figure 4. The carrier element 100 has a cubic shape (Figure 4a) and is formed by a body 110 for receiving the container 200. A flap 130 allows the body 110 to be opened and closed in an airtight manner. For this purpose, a seal 140 is arranged between the flap 130 and the carrier element 100 or body 110. The opening 120 is dimensioned so that the container 200 can be inserted into and removed from the body 110.

[0054] At the opposing end faces (FIG. 4b), one side of the carrier element 100 is hermetically connected to the first section 41 of the supply line 40 or the first section 51 of the discharge line 50, and the other side is hermetically connected to the second section 42 of the supply line 40 or the second section 52 of the discharge line 50. For this purpose, the carrier element 100 has circular seals 230, 240 on the inside of the end face, and the container 200 in each case has a corresponding embodied sealing surface on the outside of the end face. The seals 230, 240 can alternatively also be arranged on the container 200 (see FIG. 5a), in which case the carrier element 100 does not require such seals 230, 240. Thus, the gas mixture used to perform hypoxic therapy and / or hypoxic training is forced through the container 200.

[0055] 5 shows an exemplary embodiment of a vessel 200 in a delivery state containing a CO2 absorber A. The CO2 absorber A is soda lime, which is a mixture of calcium hydroxide, Ca(OH)2, and sodium hydroxide, NaOH. In this exemplary embodiment, the vessel 200 is cylindrical and has open areas 210 and 220 at each end, through which the vessel 200 can be opened. The open areas 210 and 220 have openings 250 and 260, respectively.

[0056] The container 200 may have sealing surfaces at its end faces, each having a circular seal 230, 240 (Fig. 5a). In this case, the carrier element 100 itself does not have a corresponding seal for tightly connecting the container 200 to the discharge line 40 or the supply line 40 in such a way. Alternatively, the carrier element 100 has the seals 230, 240 (see Fig. 4). In this case, the container 200 itself does not have a seal (Fig. 5b).

[0057] To prevent the CO2 absorber A from being loaded with CO2 from the ambient air, the container 200 is sealed when in the delivery state. The seal S can be embodied as a plastic film and completely surrounds the container 200 (Fig. 5a). To remove the container 200, the user P opens and peels off the seal S. Alternatively, only the opening areas 210, 220, in particular the openings 250, 260 themselves, are provided with seals S, respectively. To insert the container 200 into the carrier element 100, the user P peels off the seal S. [Explanation of symbols]
