AI Technical Summary

Problems solved by technology

In some patients, especially infants, this immobilization force can cause great discomfort, causing abrasions and skin necrosis
Also, these forces may be concentrated by the mask at some pressure points on the patient's nose / face, further increasing the likelihood of long-term complications (e.g. pain or trauma to the patient's septum, upper lip, bridge of the nose, cheeks, etc.)
Similarly, in an effort to promote full contact with the patient's face, traditional nasal mask designs may closely contact the patient's upper lip directly under the outer portion of the nasal septum

Embodiment Construction

[0022] exist Figure 1A with 1B 中示出供经鼻持续正压通气(nCPAP)系统使用的婴儿鼻腔接口鼻罩20的一个实施例。鼻罩20包括鼻罩体22和基板24。鼻罩体22形成内部空腔26(最佳示于 Figure 1A ),并且大体由尾部28、中间壳部30和前部32限定。在下文提供关于各个部件的细节。然而,一般来说,基板24从尾部28伸出并且构造成建立nCPAP发生器(在 Figure 7A 中以150示出)和空腔26之间的流体连接。尾部28形成波纹管节段34(总体标示),所述波纹管节段34适于允许并促进中间壳部30相对于基板24的侧向枢转和旋转,以及缓冲作用,波纹管节段34由此可纵向地压缩。前部32继而构造成围绕病人鼻子(未示出)安置在病人鼻子上。利用该构造,鼻罩20在固定到病人时容易调节任何微小的失准,由此,壳部30 / 前部32相对于基板24有效地“浮动”。如下所述,在一些实施例中,鼻罩20包括进一步减少可能的病人不适的附加特征。按照说明书中所使用的,参照鼻罩20相对于病人的位置使用诸如“近”和“远”的方向性术语,所述鼻罩20应用于病人。因此,“近”相比于“远”更接近病人。

[0023] 鼻罩20优选是整体的同质结构,由手术安全的顺应性材料形成,所述材料能够在应用于病人皮肤时实现流体密封。例如,在一个实施例中,鼻罩20是模制的硅树脂部分。或者,也可以接受其它材料,例如柔软的乙烯基热塑性弹性体等。在替代实施例中,鼻罩20可具有其它形式,例如凝胶填充或空气填充的囊状构造。然而,对以下论述中的某些尺寸属性的引用涉及到一个实施例,其中,鼻罩20且特别是鼻罩体22,是由硅树脂或硅树脂类的材料形成的同质薄壁结构。

[0024] 在一个实施例中,鼻罩体22包括侧壁,所述侧壁作为连续结构形成部分28-32,这些部分共同限定内部空腔26。 then, figure 2 绘制了侧壁40,其将尾部28限定为包括从基板24纵向近侧延伸的第一区段42和第二区段44,区段42、44组合形成波纹管节段34。作为参照点,基板24大致限定从鼻罩体22纵向延伸的中心轴C( figure 2 ). 于是,第一区段42相对于中心轴C从基板24纵向(近侧)延伸地向内形成锥形,限定第一弯曲部46。 换句话说,空腔26的横截面面积(即垂直于 fig...

Abstract

An infant nasal interface mask for use with a nasal continuous positive airway pressure (nCPAP) system including a mask body and a base. The mask body forms a cavity and is defined by a leading portion, an intermediate shell portion, and a trailing portion. The leading portion terminates in a leading edge forming an aperture open to the cavity and having a generally triangular shape for placement over a patient's nose. The trailing portion includes a bellows segment characterized by an increased flexibility as compared to a flexibility of the intermediate shell portion. The base extends from the trailing portion opposite the leading portion and forms at least one longitudinal passage extending through a thickness of the base and fluidly connected to the cavity. The intermediate shell portion is laterally pivotable relative to the base via the bellows segment.

Description

technical field [0001] 本发明涉及用于持续正压通气(CPAP)系统的鼻罩。更具体地,本发明涉及一种在病人接受经鼻CPAP治疗时戴在病人(例如婴儿)鼻子上的鼻罩。 Background technique [0002] 多年来,持续正压通气(CPAP)疗法已经用于治疗经受呼吸困难和 / 或呼吸衰竭的病人。更近以来,已经改进了CPAP疗法以有益于通过在呼气期间防止肺萎陷以及在吸气期间辅助肺膨胀来辅助肺部发育不全的病人(特别是婴儿,尤其是早产儿或新生儿)。 [0003] 概括地,CPAP疗法需要在呼吸周期内将连续的正压传送到自发呼吸的病人的肺中。CPAP系统一般包括适于在一个或两个管道内生成或产生连续气道正压的CPAP发生器,以及连接到所述发生器的病人接口装置,其用作传送吸入和呼出气体的导管。CPAP系统可采用多种形式,包括固定流量的通风器式系统,或者可变流量系统。 [0004] 可以使用各种病人接口装置(例如,气管导管)为病人提供CPAP。然而,对于婴儿,更为理想的是使用不太侵入性的病人接口装置,特别是通过病人的鼻孔直接或间接地与鼻腔气道对接的装置。这样的系统通常称作经鼻持续正压通气(nCPAP)系统。 [0005] 由于nCPAP系统,病人接口件一般是双叉头体或鼻罩。双叉头装置包括两个叉头或插管,每个叉头或插管的大小适于插在病人的相应鼻孔内。虽然在叉头和鼻腔气道之间可以容易实现相对稳定的流体密封,但是一些病人,尤其是婴儿,对于随叉头的插入所出现的不适产生消极的反应。相反地,鼻罩装置安置在病人鼻子的上方,从而在理论上将引起较少的病人不适。遗憾地是,现有的可用的婴儿nCPAP鼻罩具有多个缺点。 [0006] 例如,可用的nCPAP鼻罩是仅仅稍微柔性的(尤其相对于与CPAP系统接界的点),从而不能调节nCPAP发生器相对于病人鼻子的任何失准。当nCPAP发生器随后相对于病人运动以校正该失准时,nCPAP鼻罩也会以类似方式运动,可能导致相对于病人面部的空气泄漏或总体的病人不适。这对于婴儿可能是特别有问题的,这些婴儿具有微小的面部特征,从而具有较少的可用表面区域以获得并维持与鼻罩的不透流体的密封。 [0007] 这样,经常需要对鼻罩施加相当大的力以确保对病人鼻子 / 脸部的不透流体的密封。例如,条带通常卷绕病人头...
