Description
Technical Field
The invention relates to the technical field of medical instruments for newborns, in particular to a nasal plug of a noninvasive ventilator for newborns.
Background
In the process of rescuing the critically ill infant in a Neonatal Intensive Care Unit (NICU), the ventilator is often used as an important rescue treatment device to assist the critically ill infant in breathing, so as to achieve the effects of improving ventilation and poor ventilation, reducing lung injury, reducing hemodynamic changes, reducing respiratory muscle work, treating respiratory failure, and avoiding complications such as brain injury. The noninvasive ventilator provides a certain positive pressure for the sick children who breathe autonomously to increase the functional residual capacity, ensure that the respiratory tract and the alveoli of the sick children are in an expansion state under the abnormal condition, prevent the alveoli from collapsing, and is mainly suitable for the sick children who have dyspnea such as apnea, respiratory distress syndrome, infectious pneumonia and the like. With the increase of the success rate of the therapy of the extremely low/ultra-low birth weight infants, the infants often need continuous positive pressure ventilation for 30-90 days.
The nasal plug is an important accessory for connecting the noninvasive ventilator with the infant, and the nasal plug type or nasal mask type auxiliary ventilation is adopted clinically for the infant, but at present, certain defects exist in the two modes in the using process:
1. rhinobyon type
(1) Because the nasal plug is connected with the air supply pipeline and is worn by the sick child, the air supply pipeline can generate backward traction force on the nasal plug, and the nasal plug can generate extrusion force on the nasal septum and the nasal tip, the nasal cavity of the sick child is easy to deform backwards after the nasal plug is worn for a long time, and the phenomenon of 'pig nose' is serious and even appears.
(2) The nasal plug air supply needs to be connected into the nasal cavity of the infant, in order to keep the nasal plug airtight and guarantee the ventilation effect, the diameter of the nasal plug is usually larger than or equal to that of the nasal cavity of the infant, the nasal plug presses the nasal mucosa for positive airway pressure for a long time, and the nasal mucosa, the nasal septum and the middle part of a person are very easily damaged and even bleeds after the nasal cavity is continuously pressed due to the fact that the respiratory mucosa of the infant is particularly delicate and fragile and has incomplete barrier function.
(3) The noninvasive assisted ventilation patient end comprises an air inlet end threaded pipe, a generator and a nasal plug, and is formed by combining three parts clinically used, after the noninvasive assisted ventilation patient end is connected with an air supply pipeline and is worn by a child patient, the phenomenon that the nasal plug and the generator fall off is frequently caused by factors such as twisting and fidgetiness of the child patient in the air supply process, so that the positive pressure ventilation is changed into normal pressure oxygen supply, and the recovery of the child disease is influenced.
2. Nose mask
For extremely low birth weight/ultra-low birth weight infants clinically, aiming at the phenomena of nasal cavity deformation, nasal mucosa crush injury/bleeding, nasal obstruction falling and the like, the nasal cavity is often treated by ways of pasting artificial skin/hydrocolloid dressing, loosening the nasal obstruction every 2 hours, coating cod liver oil in the nasal mucosa every 2 hours or replacing the nasal mask and the like, so that the workload of clinical nurses is increased, and the ventilation effect is not satisfactory. Therefore, the nose of the patient is very small and the nose bridge is short, and the nasal mask is usually dislocated in the nasal mask type auxiliary ventilation process and sometimes even dislocated to the lips or eyes of the patient; compared with nasal obstruction type ventilation, the nasal mask type auxiliary ventilation effect is not good.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a nasal plug of a noninvasive ventilator for neonates, which solves the problem that the nasal plug of the noninvasive ventilator for neonates in the prior art easily damages the nasal cavity of a patient.

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention as defined and defined in the appended claims, and all matters produced by the invention using the inventive concept are protected.
As shown in fig. 1 to 4, the nasal plug of the noninvasive ventilator for the newborn comprises a nose mask 1, wherein the nose mask 1 is connected with a ventilation box 2, an air storage chamber 21 is arranged in the ventilation box 2, an expiration hole 22 is arranged on the air storage chamber 21, an expiration valve 23 is arranged on the expiration hole 22, an air inlet threaded pipe 9 and the nose mask 1 are communicated with the air storage chamber 21, and an inhalation valve 24 is connected between the air inlet threaded pipe 9 and the air storage chamber 21.
The nose mask 1 is internally fixed with a nose plug 3 inserted into the nasal cavity with a gap, the nose plug 3 is provided with an air vent 31 communicated with an inner cavity 11 of the nose mask, the outer wall of the nose plug 3 is fixed with a moistening agent spraying mechanism 4, the moistening agent spraying mechanism 4 comprises a shaping shell 41, a moistening agent storage bag 44 and an elastic air bag 43 are sequentially arranged between the shaping shell 41 and the outer wall of the nose plug, the moistening agent storage bag 44 is tightly attached and fixed on the inner wall surface of the shaping shell 41, the shaping shell 41 is provided with a spray hole 45 communicated into the moistening agent storage bag 44, and the elastic air bag 43 is connected with an inflating device 46 positioned outside the nose mask 1 through an air duct 47.
The nasal plug 3 comprises a part inserted into the nasal cavity of a child patient and a baffle plate which is positioned outside the nasal cavity and has the function of limiting and blocking, and the baffle plate is fixed (in an integrally formed or bonded fixing mode) on the inner wall of the nasal mask 1, so that the nasal plug 3 can ventilate the nasal cavity and can also be used as a limiting mechanism of the nasal mask 1, and the nasal mask 1 is not easy to shift; meanwhile, the nose mask 1 is fixed on the face of the infant through the bandage, so that the nose plug 2 is not required to be extruded with the nasal cavity of the infant to be fixed, the nasal cavity of the infant cannot be extruded, and the nasal cavity of the infant is prevented from deforming.
The shaping shell 41 is wrapped on the outer wall of the nasal plug, an interlayer cavity 42 is formed between the shaping shell 41 and the outer wall of the nasal plug, and a moistening agent storage bag 44 and an elastic air bag 43 are arranged in the interlayer cavity 42. The deformation of the elastic air bag 43 and the moistening agent storage bag 44 can be limited by the side wall of the interlayer cavity 42 in the extrusion process, and the moistening agent can be sprayed out from the spray hole 45 more quickly in the extrusion process of the elastic air bag 43, so that the reliability and the timeliness are improved.
Preferably, the material of the shaping housing 41 is soft gel, and the high-safety silicone is usually selected, and the hardness of the shaping housing 41 needs to ensure that the extrusion of the elastic airbag 43 does not cause the elastic deformation of the shaping housing 41, so that the shaping function cannot be achieved.

The flat tube is used for ensuring that the air duct 47 is close to the outer wall of the nasal plug 3 as much as possible under the condition of ensuring the ventilation effect, so that the occupation of too much nasal cavity space of the infant is avoided, and more nasal cavity spaces of the infant are used for ventilation. The inflator 46 may be a manually operated air-filled pinch bulb, the amount of air being squeezed just enough to allow the moisturizer to be sprayed once.
The ventilation box 2 is arranged at the top end of the nose mask 1, the air inlet threaded pipe 9 is fixed at the rear end of the ventilation box 2, the air inlet threaded pipe 9 is fixed on the support 5, and the support 5 is fixed on the head bandage 6.
