Description

Noninvasive ventilator face guard

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to noninvasive ventilator face guard.

Background

Artificial ventilation is a common and effective method for treating or rescuing severe respiratory failure at present. Conventional artificial ventilation requires intubation or tracheotomy (invasive ventilation), invasive treatment also causes pain to the patient, and also causes various complications (such as VAP). Therefore, although the curative effect is reliable, invasive ventilation is considered only when respiratory failure is clinically serious and endangers life. With the development of medicine, it is clinically desirable to reduce the endotracheal intubation or tracheotomy and corresponding complications of acute respiratory failure by means of non-invasive positive pressure ventilation (NIPPV); reduce the dependence of the patient with chronic respiratory failure on the breathing machine, reduce the pain and the medical expense of the patient and improve the quality of life.

Since Meduri et al reported in 1989 that acute respiratory failure was treated by mask NIPPV, the great attention has been drawn, and in more than 30 years, there are many reports from the aspects of application indications, application methodologies and action mechanisms, and the like, and the reports are important research subjects of respiratory medicine and critical care medicine. However, although NIPPV has been widely used in clinical practice, many problems still exist in practical use, which may lead to the failure of NIPPV. By NIPPV failure, it is meant that the patient using NIPPV must be replaced with an endotracheal tube or die. The incidence rate varies greatly depending on various factors such as the cause of AFR of patients, and is about 5% to 60%. It was found that unsuccessful NIPPV was independently associated with death of the patient, especially for newly initiated AFR. This indicates that NIPPV is selected with caution and close monitoring is required to allow timely replacement of the endotracheal tube when necessary. The mask is intolerant. Although much effort has been devoted to developing new ventilator interfaces to increase the tolerance and comfort of NIPPV patients, mask intolerance remains a major cause of NIPPV implementation failure. Such as inconsistent application indications, lack of standardized procedures, and improved efficacy and compliance.

NIPPV has common adverse effects such as dry mouth and throat, mask compression, nasal bridge skin injury, fear (claustrophobia), flatulence, aspiration, gas leakage, sputum excretion disorder, sleep upper airway obstruction, etc. The failure of NIPPV treatment, except the limitation of itself, one of them reason is gas leakage, the face guard does not match with facial size, perhaps patient has the stomach tube of remaining, the feeding tube etc., the gap of face guard and face has been increased, can obviously influence supplementary ventilation effect and synchronism, the position of adjustment cover and the tension of fixed band reduce gas leakage, will make the face guard have certain oppression to the face again, too long-time oppression can cause the obvious discomfort of patient, the damage of bridge of the nose skin even, make patient unable tolerate.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art's the aforesaid, the utility model provides an effectively improve noninvasive ventilator face guard of patient's travelling comfort.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:

the noninvasive ventilator mask comprises a mask body printed by a 3D printing technology, wherein a nose groove covering the upper end of the nose of a patient is formed in the upper end of the mask body, a closing opening is formed in the lower end of the mask body, and an adsorption pad is arranged on the closing opening; the side surface of the mask body is provided with at least one flow guide groove, a placing groove is arranged below the flow guide groove, the flow guide groove is communicated with the placing groove, and the flow guide groove is communicated with the edge of the nasal groove; an elastic one-way valve is arranged in the diversion trench and the placing trench.

The beneficial effects of the utility model are that: this scheme is used for using with noninvasive ventilator is supporting, can not lead to the fact the oppression to bridge of the nose and face, increases patient's travelling comfort, reduces face guard gas leakage, realizes that the efficient does not have the wound and ventilates. Keep somewhere the pipeline through one-way valve and fix, provide the passageway for the pipeline of keeping somewhere of nasal cavity, make to keep somewhere the pipeline and can fix in facial, keep somewhere the pipeline and can not deviate from along with the face guard because of the face guard removes, reduce the adverse event and take place.

When the noninvasive ventilator supplies air, the airflow on the inner side of the mask can not flow out of the one-way valve, and air leakage caused by the gaps between the indwelling pipeline and the mask and the face is reduced. Simultaneously, the usable 3D printing technique of face guard body produces, can set up position and the number of guiding gutter on the face guard and place the groove in a flexible way as required, can fix many with keeping somewhere the pipeline, makes to keep somewhere the pipeline more stable.

Detailed Description

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 various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

As shown in fig. 1 to 4, the noninvasive ventilator mask of this scheme includes the face guard body 2 of transparent soft silica gel material, and the face guard body 2 can adopt 3D printing technique to produce, and the nose groove 3 that covers in patient's nasal part upper end has been seted up to the upper end of face guard body 2, and the lower extreme of face guard body 2 is provided with the binding off, is provided with adsorption pad 1 on the binding off.

As shown in fig. 4, in the present scheme, a diversion trench 7 can be arranged on the side surface of the mask body 2, a placement groove 6 is arranged below the diversion trench 7, at least one-way valve is arranged in the diversion trench 7 and the placement groove 6, and when only one indwelling pipeline is in the nasal cavity of a patient, only one diversion trench 7 and one placement groove 6 need to be arranged.

As shown in fig. 1, in the scheme, two flow guide grooves 7 can be further formed in the side face of the mask body 2, the positions of the two flow guide grooves 7 correspond to the positions of the nostrils of the patient, a placing groove 6 is formed below each flow guide groove 7, the flow guide grooves 7 are communicated with the placing grooves 6, and the flow guide grooves 7 are communicated with the edges of the nasal grooves 3; two first one-way valves 4 are arranged in the diversion trench 7, a gap is arranged between the two first one-way valves 4, three second one-way valves 5 are arranged in the placing trench 6, and a gap in a Y-shaped line is arranged between the three second one-way valves 5.
