Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nasal plug component of a ventilator which is convenient for adjusting the position. Background Art

[0002] When a newborn is receiving positive pressure respiratory therapy, the hydrocolloid dressing is first pasted on the newborn's face, and then the ventilator nasal plug assembly is glued to the hydrocolloid dressing. This way of pasting is not as sticky as it was at the beginning after it is torn off, and it is easy to fall off. When the position of the respiratory therapy device needs to be adjusted, it can only be replaced with a new device, which increases the cost of treatment. In addition, since the size and spacing of the nasal cavity of each newborn are different, there may be only a few models of ventilator nasal plug assemblies at present. After comparing the size of the nasal plug and the nasal cavity, a relatively suitable nasal plug is selected. However, in many cases, the nasal plug and the nasal cavity are not compatible, which will cause the ventilator pressure to fail to reach the set value. After use, it is found that it is not compatible with the nasal cavity of the newborn patient, and it is either used reluctantly or replaced again, which not only increases the cost of treatment but also causes waste.

[0003] Based on the above reasons, the utility model provides a nasal plug assembly for a ventilator that is easy to adjust its position. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a ventilator nasal plug assembly that is easy to adjust the position. By providing a first Velcro hook surface on the upper surface of the hydrocolloid dressing and a first Velcro fur surface on the lower surface of the connecting piece, the connection and removal of the two are facilitated. In some cases, when the nasal cannula assembly needs to be removed and reused, it can continue to be adhered; and the adhesion position can be adjusted according to the face size of different newborns.
