Abstract

The invention relates to the field of human neonatology, in particular the treatment of respiratory disorders. The aim of the invention is a doppellaeufiger nose tube for the CPAP respiratory aid, which avoids the problems of known solutions and in its application physiologically safe, reliable, handy, clear and pleasant for the patient. The essence of the invention consists in a specially the anatomically functional conditions of new and early infants bersichtigenden shaping of the tube, thereby permitting fixation on the face plate, the attitude stability and reliability, thus also associated freedom of movement for movements of the child's head, also in the use of physiologically uncritical Rueckverformungskraefte from the Tubusmaterial for the required pressure of the tube in the contact area of the nasal entrance level and in the due to shaping, fixation mode and choice of materials manageability and clarity. The tube is intended for use in the treatment of respiratory distress syndrome and other respiratory disorders of newborn and premature infants.

Description

Device for influencing the respiratory system in hay infants

Field of application of the invention

The invention relates to a device for influencing the respiratory system in newborns, consisting of a double-barreled nose tube, the neonatal intensive care and care, especially the treatment of respiratory syndrome, in the supply of supplies in the delivery room, on transports and in the definitive inpatient care New and premature babies serve.

Characteristic of the Known Technical Solutions Double-barreled nose tubes are known in which two thin, calibrated tubes, known as nose pieces, emerge from the middle of a bd. Tube, which is open for coupling and designated as the main part of the tube.

There are further known double-barreled nasal tubes, in which for the coupling of the tube in the supply and discharge system of the conditioned respiratory gases only a common opening is present.

All known solutions are liable to the lack of attachment of the tube on the head of the Kinde3 by means of fixation relatively difficult, and large forces are required to produce the required for the effectiveness of the respiratory aid tightness in the nostrils and a stable position of the tube ,

This is a necessary consequence, as it results from the nature of the connection of the tube with the system of the respiratory gas inlet and outlet hoses.

Where the magnitude of the pressure of tube material on the body tissue leads to the disturbance of the microcirculation, necessary disruption of the respiratory aid, local tissue death, subsequent disfigurement and functional disorder, threatened

It is known that in order to alleviate such dangers, a mechanical fixation of the head is practiced, whereby asymmetric pressure is to be avoided by movement-related tilting of the head with respect to the tube and leakage of the system.

It is also known that the risk of pressure damage in the nasal entry area is attempted by interposing double perforated discs. The same purpose serves the use of soft as possible basic substances for the tube. The well-known tubes continue to adhere to the lack of transparency, so that precipitation of condensate o. Ä. Do not recognize ·

However, devices are also known, wherein the respiratory support is carried out by means of tight-fitting, the nostrils and the mouth into a same chamber involving monstrous mask, which are wide and circularly fixed on the head. This represents another solution, which avoids the risk of pressure damage in the nasal entry area, but on the other hand has crucial other deficiencies, which stood in the way of a proliferation of these devices.

Object of the invention

The aim of the invention is to avoid any local traumatization, to keep the position of the tube stable, to ensure an undisturbed function of the respiratory aid (GPAP method, ie continuous positive airway pressure), preferably to the child

To maintain a free mobility of the head, to spare him the annoyance of inadequate fixation aids and to make the care by the staff clear and easy.

Keeping the mobility of the head, saving annoying Pixationshilfen, transparency of the material used and

Clarity and manageability in the care distinguishes ·

At the S'tirnplatte of the head, a tubular main piece with adhesive plaster 11 is attached. The main piece 1 has the shape of a "U". At the main part 1, two nose pieces 2 are arranged symmetrically. Between main piece 1 and nose pieces 2, a gas flow can flow unhindered. The diameter of the turf pieces 2 corresponds to the outside about the nostrils 13 of the child.

The shape of the (tube is further characterized by a curved course of the main piece 1 in the region of the U-legs of the transition to the U-Basis4als Übe'rgangskrümmung designated 7 "and in the 'U' base 4, from.

When fixing the concave tube U-legs 5 on the flat face plate IO, the posterior deformation of the curvature of the tube U-legs 6 produces a contact pressure which becomes effective in the base area and which is directed towards the upper lip 2Qhin. By simultaneous crest-directed train on the tube-U-legs 5 before the final fixing rolls the more pronounced transition curvature 7 between tube U-leg 5 and U-Bais 4, wherein a pressure of the base results in the contact zone 4 of the nasal entry plane , This is supported by the balance of the convex curvature of the U-base 4 taking place in the process.

-The rotation of the U-base 4 connected to the compensation process of the Übergarrgskrümmung 7 about its axis course simultaneously requires the pivoting of the front-end-facing nose pieces 2 in an approximately horizontal plane corresponding to the course of the nasal passages 12 ·

The pressure forces resulting from the return deformation of the tube curvatures 6, 7, 8 are physiologically completely uncritical in accordance with the properties of the soft FVO used with a high proportion of plasticizer. However, they ensure that to hold. the nosepiece 2 in nominal position and for the sealing of the system required proof *

For the pptimalen pressure distribution of the U-base 4 of the tube in the contact area perforated Scha are umgumaiir ing e 3 pushed over the nose pieces 2, each with its level in the individually different angles to the other side nostrils 13 finds a separate consideration · So can material stresses avoid over the nose bridge area 15, as they occur in double perforated foam rubber sheets. On the contrary, in the contact zone of the donut rings 3 above the bridge of the nose, an increase in the ability to adapt to the underlay is obtained.

In order to protect this vulnerable region of the nose bridge region 15, according to the invention, there is also an impressed dent 9 in the U base region 4 between the nose pieces 2. The FVG material used has opaque transparency. It is of silicone rubbery softness »

The nose pieces 2 are dulled at the free end 10 to protect the tissue in the contact area.

The main piece 1 has a length of 280 mm.

The free length of the nose pieces 2 is 10, 11 or 12 mm, their diameter 2.5 x 3.5; 3x4; 3.5 χ 4.5 mm.

They are self-holding by means of a corresponding inner and outer abutment. 16, 17 in corresponding openings 11.

Embodiment ·

The tube consists of a main piece 1 and two nose pieces 2 "The main piece 1, which has the shape of a" U "in plan view, the base of which rests with the two nose pieces 2 of the nasal entry plane, where the connection to the airways 18 of the child is made ,. ,

Since the distance between the nasal entrance plane and mounting surface of the tube U-leg 5 on the end plate 10 remains constant even during head movements and the gas-carrying hoses of the entire CPAP system can be brought from axially results in a high mobility of the lying head about its longitudinal axis, without tensions in the tube.

In the field of application, e.g. the neonatal Erstversorgungsplatz, already connected to the system of gas conditioning tubes are kept ready · The child to be cared for after cleaning and degreasing the face plate 10 there is a broad patch strip substrate. 11 glued on. After introducing the coated with ointment nose pieces 2 in the nostrils 13 and light pull on the tube U-legs 5 stirnwarda they are glued by means of a plaster 19 on the already existing adhesive tape backing 10. There is no need for any cumbersome fixation procedure with ligaments and complicated bandages on the face or at the temples. The therapeutically possibly f. hairy head needed for other purposes remains free. The effectiveness of the breathing aid is given immediately with insertion of the nose pieces 2. The installation of the tube can be easily done by a single nurse.

The question of the usefulness of the method in this case can already be decided before the final fixation of the tube.
