Medijet. Active nCPAP interface

"" ""

Product benefits

  • Low noise level
  • Pressure trigger and spontaneous breath detection without additional sensor
  • Flexible adapter for positioning prong and mask
  • Patented flextubes for easy application
  • Based on the Benveniste valve with volume reservoir
In this video we shortly demonstrate how to correctly use the medin Medijet generator. Medijet supports spontaneous breathing of neonatal patients – premature as well as term newborn. Based on the Benveniste principle Medijet provides an adjustable constant positive pressure in the patient´s airway applicated through short binasal prongs and masks. Benefits: - Increase of FRC and improvement of lung compliance - Decrease of WOB - Less noise level Pulmonary gas transport can be improved and atelectasis prevented by nCPAP.

Quiet and comfortable

Medijet is our active nCPAP generator and is used on the medin devices medin-NC3, medinCNO, medinCNOmini and medinSINDI. In addition, the interface can also be combined with several special ventilators.

Medijet is quieter than comparable nCPAP
generators (Kirchner L, Wald M, Jeitler V, Pollak A. In vitro comparison of noise levels produced by different CPAP generators. Neonatology. 2012;101(2):95-100. doi:10.1159/0003295581​) and features a high level of comfort.

Benveniste valve

Medijet actively generates CPAP pressure using a modified Benveniste valve (Benveniste D, Berg O, Pedersen JE. A technique for delivery of continuous positive airway pressure to the neonate. J Pediatr. 1976;88(6):1015-1019. doi:10.1016/s0022-3476(76)81066-92​), that is, directly in the generator, and thus the continuous positive pressure in the patient’s airway without an additional valve in the NIV device. As a result, Medijet is connected to the device with only a single-tube system. This facilitates handling and patient positioning.

Accessories

Medijet is secured to the patient’s head with the user-friendly medin bonnet. Medijet is applied to the nose of the small patient using short binasal prongs or soft, gentle nasal masks.

INTRODUCTION

Minimization of noise exposure is an important aim of modern neonatal intensive care medicine. Binasal continuous positive airway pressure (CPAP) generators are among the most important sources of continuous noise in neonatal wards. The aim of this study was to find out which CPAP generator creates the least noise.

METHOD

In an experimental setup, two jet CPAP generators (Infant Flow® generator and MediJet®) and two conventional CPAP generators (Bubble CPAP® and Baby Flow®) were compared. Noise production was measured in decibels in an A-weighted scale [dB(A)] in a closed incubator at 2 mm lateral distance from the end of the nasal prongs. Reproduction of constant airway pressure and air leak was achieved by closure of the nasal prongs with a type of adhesive tape that is semipermeable to air.

RESULTS

The noise levels produced by the four generators were significantly different (p < 0.001). Values measured at a continuous constant flow rate of 8 l/min averaged 83 dB(A) for the Infant Flow® generator with or without sound absorber, 72 dB(A) for the MediJet®, 62 dB(A) for the Bubble CPAP® and 55 dB(A) for the Baby Flow®.

CONCLUSION

Conventional CPAP generators work more quietly than the currently available jet CPAP generators.
