Definitions
- the field of the invention relates to applicators for nasal cannulae of the type defined in the preambles of the independent patent claims.
- the invention relates to the field of nasal cannulae, which are used for pneumatically splinting the respiratory tract.
- CPAP therapy Continuous Positive Airway Pressure Therapy
- a patient is supplied via a nose mask with a continuous positive airway pressure relative to the ambient air pressure.
- This positive airway pressure if chosen appropriately, ensures that the upper respiratory tract remains completely opened during the whole night, so that no obstructive respiratory disorders occur.
- pneumatically splinting the respiratory tract The necessary positive airway pressure depends, inter alia, on the sleep phase and the position of the body of the sleeping person.
- a therapy apparatus AutoCPAP
- WO 02/083221 A2 which adjusts the positive airway pressure automatically, thereby adapting it to the sleep phase and the position of the body.
- BiPAP apparatus and multilevel apparatus have been developed. These apparatus have the property to support the patient's breathing by reducing the positive airway pressure as he is exhaling and by increasing the positive airway pressure again as he is inhaling. That is, these apparatus work with at least two pressure levels.
- Such apparatus are known, for instance, from DE 691 32 030 T2 and WO 02/26283 A2.
- oxygen nasal cannulae for the oxygen treatment are known from the prior art.
- air at an increased oxygen partial pressure (>210 mbar) or pure oxygen is administered into the patient's nose.
- An oxygen treatment is carried out, for instance, in case of an acute or chronic hypoxemia resulting from a respiratory or cardiovascular disorder (myocardial infarction, shock) or certain intoxications caused, for instance, by carbon monoxide, carbon dioxide, coal gas or smoke.
- oxygen nasal cannulae in an anti-snore apparatus is known from WO 02/062413 A2.
- oxygen nasal cannulae are designated as nasal cannulae.
- WO 02/062413 A2 further discloses nasal cannulae having integrated jet pumps, which are illustrated in FIGS. 4 and 5 of 02/062413 A2.
- FR 2 827 778 discloses an apparatus which is designated as a monolithic part and resembles the nose part of a nasal cannula.
- the apparatus serves to support a patient's respiration without or with insufficient spontaneous respiration through the nostrils.
- the dimensions are adapted to premature infants.
- Distal, tubular elements project into the nostrils. Foamed discs around the tubular elements serve as a resilient stop.
- the tubular elements are placed in two dome-shaped sleeves which are connected by a bridge on the side of the sleeves facing away from the nose. Two ducts are supplied with a respirable gas in parallel.
- a capillary tube serves as a pressure probe.
- a supply device receives through the capillary tube a pressure drop and can supply the patient with a continuous or pulse-shaped jet of respirable gas. After an inspiration phase the supply device is instructed by the pressure transmitted through the capillary tube to stop the gas supply. Thus, the patient is able to freely exhale.
- a valve in a wall of the body of the applicator, with the valve allowing gas only from the ambience to flow into the body of the applicator, has the surprising advantage that the user is not exposed to the risk of suffocating if the connected compressor is defective.
- a top slipped over the prongs can adapt the outer shape of the prongs in a surprisingly simple fashion to the inner shape of the nostrils of a patient.
- the small, relatively simply shaped top has a patient-specific shape, and not the large nasal cannula whose shape is relatively complicated. Hence, greater quantities of the nasal cannula and, thus, a reduction of costs are achieved.
- a bridge between the two sealing cones of the top on their side facing the body ( 11 ) prevents a single sealing cone from getting lost. Furthermore, in a surprisingly simple fashion, the sealing cones are prevented from turning out of position on the prongs. Finally, the bridge also prevents the top from unintentionally getting pulled off from the prongs.
- Rim-shaped sealing lips on the side of the sealing cones facing away from the body of the applicator produce a comfortable tight connection with the inner wall of the respective nostril.
- the sealing cones are partially hollow between an inner part and an outer cone so as to allow a gas flow between the inner part ( 31 , 32 ) and the respective outer cone ( 33 , 34 ) parallel to the inner part ( 31 , 32 ), the additional air resistance in the nostril is kept small by the applicator.
- the collar on the nose-sided end of the prongs advantageously prevents the top from unintentionally getting pulled off.
- the cover permits a simple mounting of the flexible membrane.

- the sealing cones are, in fact, slightly smaller than the openings of the user's nostrils. This small gap is bridged and sealed by sealing lips 25 , 26 , 27 and 28 .
- the sealing lips 25 , 26 , 27 and 28 themselves have approximately the shape of a circumferential surface of a very flat cone. This means that they extend from the inward top to the outward bottom. As a result of this shape the sealing cones can be easily introduced into the nose and represent a small resistance to prevent the applicator from slipping out of the nose.
- the sealing cones 23 , 24 are connected to each other on their lower end, which is away from the nose and close to the body, by a bridge 29 in order to prevent the sealing cones 23 , 24 from being pulled off from the prongs 18 , 19 too easily and to prevent the sealing cones 23 , 24 from being turned out of position relative to the body 11 and the user's nostrils.

- the cover has a circumferential groove 39 on its outer edge, which engages with the wall of body 11 that limits the oblong hole 37 . Hence, the cover 15 is clamped relative to the wall of body 11 and seals the oblong hole 37 in a gas-tight manner.
- the body 11 encloses a hollow space 22 . Especially the inner surfaces of the body 11 do not have any sharp edges. Rather are all edges rounded off so as to minimize flow noises. As the wall of the body 11 has approximately the same thickness these rounded portions can also be seen on the outside of body 11 .
- FIG. 2 shows a top view of an applicator according to the invention.
- the sealing cones 23 , 24 are comprised of outer cones 33 and 34 , inner cylinders 31 and 32 and ribs 30 mechanically connecting the outer cones 33 , 34 to the inner cylinders 31 , 32 .

- On the inside the radius of the rounded portion is approximately as large as the inner diameter of the prongs 18 , 19 .
- the radius of this rounded portion on the outside is approximately half as large as on the inside. That is because the wall thickness in the region of the prongs 18 , 19 is approximately half the size as in the rest of the body 11 .
- the body is substantially broader than the tube connections 20 , 21 .
- this measure also has the purpose of reducing the flow velocity of the gas in the junction region between the prongs 18 , 19 and the body 11 by enlarging the cross-section, thereby reducing flow noises.
Abstract
Description
- The field of the invention relates to applicators for nasal cannulae of the type defined in the preambles of the independent patent claims.
- The invention relates to the field of nasal cannulae, which are used for pneumatically splinting the respiratory tract.
- In the CPAP therapy (Continuous Positive Airway Pressure Therapy) a patient is supplied via a nose mask with a continuous positive airway pressure relative to the ambient air pressure. This positive airway pressure, if chosen appropriately, ensures that the upper respiratory tract remains completely opened during the whole night, so that no obstructive respiratory disorders occur. One also talks about pneumatically splinting the respiratory tract. The necessary positive airway pressure depends, inter alia, on the sleep phase and the position of the body of the sleeping person. In order to limit the positive airway pressure, which is perceived as unpleasant, to the necessary amount a therapy apparatus (AutoCPAP) is disclosed in WO 02/083221 A2, which adjusts the positive airway pressure automatically, thereby adapting it to the sleep phase and the position of the body.
- In order to facilitate the breathing, moreover, BiPAP apparatus and multilevel apparatus have been developed. These apparatus have the property to support the patient's breathing by reducing the positive airway pressure as he is exhaling and by increasing the positive airway pressure again as he is inhaling. That is, these apparatus work with at least two pressure levels. Such apparatus are known, for instance, from DE 691 32 030 T2 and WO 02/26283 A2.
- Furthermore, oxygen nasal cannulae for the oxygen treatment are known from the prior art. By means of the oxygen nasal cannula air at an increased oxygen partial pressure (>210 mbar) or pure oxygen is administered into the patient's nose. An oxygen treatment is carried out, for instance, in case of an acute or chronic hypoxemia resulting from a respiratory or cardiovascular disorder (myocardial infarction, shock) or certain intoxications caused, for instance, by carbon monoxide, carbon dioxide, coal gas or smoke.
- The use of oxygen nasal cannulae in an anti-snore apparatus is known from WO 02/062413 A2. In this context oxygen nasal cannulae are designated as nasal cannulae. WO 02/062413 A2 further discloses nasal cannulae having integrated jet pumps, which are illustrated in FIGS. 4 and 5 of 02/062413 A2.
- US 2003/0079749 A1 and WO 2006/072231 A2 describe nasal cannulae whose nose pieces have rounded edges. The air sweeps past these edges, thereby largely avoiding hissing and whistling noises.
- FR 2 827 778 discloses an apparatus which is designated as a monolithic part and resembles the nose part of a nasal cannula. The apparatus serves to support a patient's respiration without or with insufficient spontaneous respiration through the nostrils. The dimensions are adapted to premature infants. Distal, tubular elements project into the nostrils. Foamed discs around the tubular elements serve as a resilient stop. In another embodiment the tubular elements are placed in two dome-shaped sleeves which are connected by a bridge on the side of the sleeves facing away from the nose. Two ducts are supplied with a respirable gas in parallel. A capillary tube serves as a pressure probe. At the beginning of an inspiration phase a supply device receives through the capillary tube a pressure drop and can supply the patient with a continuous or pulse-shaped jet of respirable gas. After an inspiration phase the supply device is instructed by the pressure transmitted through the capillary tube to stop the gas supply. Thus, the patient is able to freely exhale.
- It is the object of the invention to provide improved applicators for nasal cannulae.
- This object is achieved with the teaching of the independent claims.
- Preferred embodiments of the invention are defined in the dependent claims.
- A valve in a wall of the body of the applicator, with the valve allowing gas only from the ambiance to flow into the body of the applicator, has the surprising advantage that the user is not exposed to the risk of suffocating if the connected compressor is defective.
- A top slipped over the prongs can adapt the outer shape of the prongs in a surprisingly simple fashion to the inner shape of the nostrils of a patient. Thus, merely the small, relatively simply shaped top has a patient-specific shape, and not the large nasal cannula whose shape is relatively complicated. Hence, greater quantities of the nasal cannula and, thus, a reduction of costs are achieved.
- A bridge between the two sealing cones of the top on their side facing the body (11) prevents a single sealing cone from getting lost. Furthermore, in a surprisingly simple fashion, the sealing cones are prevented from turning out of position on the prongs. Finally, the bridge also prevents the top from unintentionally getting pulled off from the prongs.
- Rim-shaped sealing lips on the side of the sealing cones facing away from the body of the applicator produce a comfortable tight connection with the inner wall of the respective nostril.
- As the sealing cones are partially hollow between an inner part and an outer cone so as to allow a gas flow between the inner part (31, 32) and the respective outer cone (33, 34) parallel to the inner part (31, 32), the additional air resistance in the nostril is kept small by the applicator.
- It is an advantage of the membrane-loaded outlets on the body-sided end of the outer cones that the user does not inhale again the exhaled, used air. Moreover, the choice of the rigidity of the shim-shaped membranes allows an adjustment of the positive airway pressure produced by the applicator, which facilitates the control of the connected compressor.
- The collar on the nose-sided end of the prongs advantageously prevents the top from unintentionally getting pulled off.
- The cover permits a simple mounting of the flexible membrane.
- A preferred embodiment of the invention with reference to the accompanying drawings shall be explained in more detail below. In the drawings:
