Description

Technical Field

[0001] The present invention relates to the technical field related to medical auxiliary equipment, and more specifically, to a nasal plug for a non-invasive ventilator. Background Art

[0002] For newborns, especially extremely premature and very premature infants, the use of non-invasive ventilator-assisted ventilation in the early stages of life to prevent alveolar collapse and prevent and treat respiratory distress syndrome is a safe, non-invasive and effective method of respiratory support. More and more neonatologists use this method to treat newborns of all gestational ages, and it is one of the important means of treating critically ill newborns.

[0003] However, there is no standard way to connect and fix the nasal plug on the patient side of the non-invasive ventilator. Newborns are a special group, especially premature babies, whose skin is thin and tender and easily injured. The current method of fixing the nasal plug is mainly to bind it with multiple ropes. The operation of fixing it with ropes is complicated, easy to loosen and displace, the tightness is difficult to control, and the thin ropes used for fixing are prone to breed bacteria, increasing the risk of nosocomial infection in newborns. Summary of the invention

[0004] The purpose of the present invention is to provide a nasal plug for a non-invasive ventilator that is easy to fix, so as to solve the above-mentioned technical problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a nasal plug for a non-invasive ventilator, the nasal plug comprising an adhesive wing and a base, the two sides of the base are respectively connected to different adhesive wings, a pressure channel is provided on the base, the two ends of the pressure channel are respectively located on the top surface and one end side of the base, the pressure channel located on the top surface of the base is connected to the terminal pressure airflow output hole of the non-invasive ventilator, the pressure channel located on the side of one end of the base extends into the nasal cavity, and the pressure channel is used to transport gas; the top surface of the base is inclined upward, and the other end of the base is provided with a slope;

[0006] The adhesive wing and the base are both made of flexible materials, and the bottom surfaces of the adhesive wing and the base are provided with hydrocolloid dressings. The hydrocolloid dressing is used to fix the base by sticking the adhesive wing to the face and sticking the base to the skin between the nose and lips; the adhesive surface of the hydrocolloid dressing is provided with a tearable protective film, and when the adhesive wing needs to be torn off, a lubricating liquid is applied around the hydrocolloid dressing to reduce the viscosity of the hydrocolloid dressing.

[0007] A further technical solution of the present application is that the hydrocolloid dressing is hydrophilic.

[0008] A further technical solution of the present application is that the adhesive wing is integrally formed with the base.

[0009] A further technical solution of the present application is that reinforcing ribs are provided at the connection between the adhesive wing and the base.

[0010] A further technical solution of the present application is that the angle of the slope is 15°-45°.

[0011] A further technical solution of the present application: the angle of the slope is 30°.

[0012] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0013] The present invention replaces the use of binding ropes to fix the base by arranging adhesive wings to fix the base on the cheeks, which is simple and convenient to operate and avoids the problems of troublesome fixing by binding ropes, easy loosening, easy displacement, difficult to control tightness, and the thin ropes used for fixing easily breeding bacteria, thereby increasing the risk of nosocomial infection in newborns. In addition, the hydrophilic hydrocolloid dressing becomes less viscous under the action of lubricating liquid, thereby facilitating tearing and peeling off without hurting the skin or leaving traces, thereby avoiding damage to the skin of newborns when removing the nasal plug.
