  • Multi-part respiratory mask associated nose connection element and associated combination of a hose connection element and a coupling element
  • the present invention relates to a multi-part respiratory mask for supporting the breathing of a patient, in particular a respiratory mask for premature babies and toddlers, as well as an associated nose connection element and an associated combination of a hose connection element and a coupling element.
  • Respiratory masks are used, among other things, for breathing support in intensive care units. These respiratory masks are designed in different sizes and shapes for the typical nasal shapes, so that essentially a form-fitting respiratory mask is available for each nasal shape.
  • the respiratory mask has a connection area for connection to a respiratory pump.
  • a T-shaped adapter piece connects the connection area with two tubes of the ventilation pump for the supply and removal of respiratory gases.
  • the ventilation pump is permanently active so that a continuous flow of air flows through both hoses.
  • connection tube between the connection area of the respiratory mask and the branch of the T-shaped adapter piece is flushed by the active breathing of a patient.
  • air flows from the ventilation pump through the connection tube into the ventilation mask.
  • the lung forces the spent air through the connection tube towards the respiratory pump against the air pressure of the ventilation pump, where it is entrained by the continuous air flow. In such.
  • breathing in the patient breathes the used air left in the connection tube after the last exhalation.
  • the lung volume is low, as well as in patients with lung damage.
  • the proportion of inhaled spent air is not negligible in such patients.
  • the impending lack of oxygen is compensated by increasing the oxygen content in the respiratory gases.
  • connection area the T-shaped adapter piece and the hoses are rigidly connected.
  • a tensile load may be applied to the tubing causing the respiratory mask to no longer be tight against the patient's nose.
  • the functionality of the respiratory mask is then no longer guaranteed.

  • a multi-part respiratory mask can be created, which has a soft, elastic nasal connecting element, which can be applied sealingly against the patient, rigid pivotal elements, realized by the coupling element and the hose connection element, ensure a high level of functional reliability. Due to this rotatability of the hose connection element with respect to the coupling element, the gas outlet and the gas inlet can follow a movement of the patient, whereby connection tubes between the ventilation mask and the gas purging device can be kept draft-free. This ensures a secure fit of the respiratory mask on the patient's nose.
  • the non-rotatable clamping of the coupling element in the Nasenan gleichelement also increases the reliability because the nasal connection element can not detach from the coupling element and also the gas opening of the coupling element can not be closed by a movement of the patient, and further reduces the volume of spent breathing gas in the anteroom in front of the nose to a nearly negligible value.
