Description

一种医用压力袜 技术领域
本发明涉及压力袜技术领域，更具体地说，涉及一种医用压力袜。
背景技术
医疗压力袜(MCSs，Medical compression stockings)是治疗静脉曲张的一个重要的组件。医疗压力袜子设计为压力自肢体的下部至上部逐渐减小，从而增大静脉流速，减轻静脉壁的肿胀，提高瓣膜功能，从而有助于改善静脉血自远端至近端的回流。
压力袜通常为针织结构，其由编织纱和衬垫纱构成。通过调整针织工艺、衬垫纱及结构的参数，从而针对不同使用者制造出具有不同压力级别、尺寸及形状的压力袜。
然而，由于下肢的截面形状是不规则的，即，自下部至上部，下肢的截面形状是由不规则形状改变为椭圆形。针对不规则形状，压力袜无法对于肢体的下部施加均匀且准确的压力。特别是在脚踝处，压力袜的压力无法施加于贴近骨头的位置，压力袜与脚踝处之间存在空洞区，因此，脚踝侧所受压力不充足，远远小于其他部分的压力，导致静脉功能不全的患者于此处经常容易发生溃烂。
发明内容
基于上述问题，本发明提供了一种医用压力袜，其能够优化腿部，特别是脚踝的压力分布，且能够对压力进行监控。
为达成上述目的，本发明提供一种医用压力袜，其包括本体、辅助压力部及压力感测部。本体由编织纱和衬垫纱纺织形成。辅助压力部与本体集成为一体，且位于医用压力袜的下肢脚踝处，并能够与穿着者的脚踝接触。压力感测部包括传导部和信号接收部，传导部与本体集成为一体，用于感应医用压力袜的相应部位的压力，信号接收部能够接收来自传导部的信号，并根据所述信号确认相应部位的压力值。

根据一实施例，垫片的材料为硅胶，辅助压力部还包括辅助织物，硅胶夹设于本体与辅助织物之间，辅助织物的面积大于或等于硅胶的面积，辅助织物与穿着者的内踝直接接触。
根据一实施例，传导部包括柔性导电部，柔性导电部织入本体，以与本体成为一体，柔性导电部通过电阻或者电容变化来感知压力大小变化。
根据一实施例，柔性导电部为柔性导电线或者导电弹力包缠纱，柔性导电部通过成圈、添纱或者衬垫的方式织入本体。
根据一实施例，传导部的数量为一个或多个，其设置于本体的一个或多个位置。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本发明更全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。在图中，为了清晰，可能夸大了区域和层的 厚度。在图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
此外，所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。在下面的描述中，提供许多具体细节从而给出对本发明的实施例的充分理解。然而，本领域技术人员将意识到，可以实践本发明的技术方案而没有所述特定细节中的一个或更多，或者可以采用其它的方法、组元、材料等。在其它情况下，不详细示出或描述公知结构、材料或者操作以避免模糊本发明的主要技术创意。
现有的压力袜无法对于肢体的下部施加均匀且准确的压力。特别是在脚踝处，压力袜的压力无法施加于贴近骨头的位置，压力袜与脚踝处之间存在空洞区，因此，脚踝侧所受压力不充足，远远小于其他部分的压力，导致静脉功能不全的患者于此处经常容易发生溃烂。
一实施例提出以下研究：在压力袜的脚踝处增加一可分离的垫部，以实现对此处的施压。通过嵌入此垫部，能够改善脚踝处的压力，并且由于垫部的厚度使得此处的压力增大。然而，由于穿着时可分离的垫部易于移位，使得在实际使用过程中存在极大的不便和不准确。
此外，一实施例提出一种压力测量系统，其可包括体内测量和体外测量。体外压力测量通常使用测试设备，以金属或气囊探针来测量压力袜与人造腿之间的压力。然而，此测试方法与实际接触状态存在偏差，另一实施例是对压力袜进行拉力测试，后续还需公式来计算压力。
体内压力测量是指测试者直接测量压力袜与腿部之间的压力。然而，此方法存在不便，非专业人员难以执行。因此，到目前为止，仍未出现集成于压力袜的压力监测系统。
为解决上述问题，本发明提供一种医用压力袜，如图1、2、5所示，其包括本体10、辅助压力部20及压力感测部30。本体10由编织纱和衬垫纱纺织形成。辅助压力部20与本体10集成为一体，且位于医用压力袜的下肢脚踝处，并能够与穿着者的脚踝接触。压力感测部30包括传导部和信号接收部，传导部与本体10集成为一体，用于感应医用压力袜的相应部位的压力，信号接收部能够接收来自传导部的信号，并根据所述信号确认相应部位的压力值。
也就是说，本发明是在医用压力袜的下肢脚踝处一体的集成有辅助压力部，穿着时，辅助压力部能够适当的填补内踝与胫骨之间的空洞区，补偿此部分的压力，使得来自压力袜的压力传递给脚踝，因此脚踝的压力均匀，从而能够优化腿部，特别是脚踝的压力分布，避免静脉功能不全的患者于发生溃烂。并且，由于辅助压力部与本体集成为一体，二者不可分割，因此，在穿着及穿脱过程中，辅助压力部均不会相对于本体发生移位，能够始终保持在对应于下肢脚踝处的位置，因此，保证了使用的准确性和便利性。
并且，医用压力袜还集成有压力感测部，从而能够实时测量医用压力袜施加于腿部的压力，且测量值具有极高的准确性和可靠性，因此，有助于穿着者对于医用压力袜的舒适性进行监控。
相比于前述提到的体内测量和体外测量，本实施例将压力感测部集成于医用压力袜，能够对真实情况下的压力进行实时监控，因此具有极高的准确性和可操作性。
在一实施例中，信号接收部还能够将检测到的压力值与预设的压力标准阈值比较，当超出预设的压力标准阈值时，向穿着者发出提醒。其中，预设的压力标准阈值可根据压力标准级而设置。因此，穿着者能够根据所测的压力值与预设的压力标准阈值的比较，判断医用压力袜提供的压力是否合适，若压力过高或过低时，均可得到提醒。
此外，在其他实施例中，压力感测部30还可应用于除医用压力袜以外的领域，例如，集成于其他需要监控压力的压力衣物，可在压力治疗方面对病人、医疗人员、医药制造者提供帮助。
综上，本实施例提供一种集成有辅助压力部20及压力感测部30的医用压力袜，其能够对脚踝处有效的提供压力及实时准确的压力监控，且使用方便、结构简单、便于制造。
以下，通过一具体实施例对医用压力袜的辅助压力部20的结构进行详细说明。
其中，医用压力袜的本体10是由编织纱和衬垫纱共同组成，在一些 实施例中，袜跟部分不包括衬垫纱。
其中，编织纱编织成地组织，而衬垫纱以衬垫的形式夹在地组织中。编织纱和衬垫纱均二者或者其中之一可为单层或双层的弹力包缠纱，弹力包缠纱包括外层的包缠纱线和内部的弹性纱芯。
包缠纱线的材料例如为尼龙、绵、或以生物型的PLA/PHBV材料成形的细丝、假捻变形丝或喷气变形丝。弹性纱芯的材料例如为氨纶、橡胶、或其他具有弹性的细丝或纱线。
优选的，衬垫纱的弹性纱芯的内径相比于编织纱较大，从而为医用压力袜提供更大的弹力。
其中，如图1至图4所示，辅助压力部20的数量为一个，并能够与穿着者的内踝直接接触。在一些实施例中，辅助压力部20的数量为多个，其可以任意方向间隔或连续的排布。辅助压力部20的形状、数量、位置可根据需要适当的改变。
其中，辅助压力部20包括毛圈结构，如图8、9所示，毛圈结构以织工艺与本体10集成为一体。
对应于辅助压力部20的编织纱采用集圈织法形成为多个连续的集圈结构，每一集圈结构包括线圈，每一线圈上缠绕一毛圈结构。
也就是说，本实施例中，整个医用压力袜的大部分区域的编织纱均采用平针结构，仅在辅助压力部20的位置处，编织纱采用连续集圈结构。
图9示意性的示出了辅助压力部20的结构，其中，白色表示作为地组织的编织纱11，黑色和灰色的纱表示毛圈结构12，为了清楚的示出毛圈结构，图9未示出夹在编织纱中间的衬垫纱，而实际上，本实施例中，辅助压力部20包括编织纱、衬垫纱及毛圈结构。
本实施例中，沿经线方向，集圈结构为可连续设置的2-3个，沿纬编方向，集圈结构可为连续设置的3-5个。其中，集圈结构的另一作用为使该部分织物的组织更加紧密、厚实，从而能够提高与皮肤的贴合度。因此，在其他实施例中，辅助压力部20可为集圈结构，无需包括毛圈结构。
应当理解，集圈结构的数量、排布仅为示例，可根据需要进行调整。
毛圈结构的形式不限于此，在另一实施例中，毛圈结构以绣工艺与本体10集成为一体。即，毛圈结构为绣在医用压力袜的里侧。对于绣的毛 圈结构，此处只需绣出连续的集圈。
毛圈结构的材料为天然纤维或人造纤维，例如尼龙、棉纱等。可根据下肢的形状、轮廓和压力分布对毛圈结构的高度、压力及排布进行调整。
图10示出了医用压力袜的拉伸应力与伸长率的关系示意图。其中，横坐标表示伸长率，纵坐标表示拉伸应力，L1至L4分别为四种医用压力袜的上述关系曲线，即，L1为普通针织结构，L2为集圈形式的针织结构，L3表示具有毛圈的普通针织结构，L4表示具有毛圈的集圈形式的针织结构。
根据拉普拉斯公式，P＝F/r，表示压强与F(在此即拉伸应力)正相关，根据图10可以看到，集圈形式和/或具有毛圈的针织结构的拉伸应力都有所提高。
辅助压力部20的形式和结构不限于此，在另一实施例中，辅助压力部20可包括垫片，垫片缝于医用压力袜的下肢内踝处。
其中，垫片的材料可为硅胶，辅助压力部20还包括辅助织物，硅胶夹设于本体10与辅助织物之间，辅助织物的面积大于或等于硅胶的面积，辅助织物与穿着者的内踝直接接触。
也就是说，本实施例中，辅助压力部20是由三层结构组成，外侧是医用压力袜的织物，中间是垫片，里侧为辅助织物，其与皮肤接触。
以下，通过一具体实施例对医用压力袜的压力感测部30的结构进行详细说明。
本实施例中，如图5、6所示，传导部可包括柔性导电部31，柔性导电部31织入本体10，以与本体10成为一体，柔性导电部31通过电阻或者电容变化来感知压力大小变化。
其中，柔性导电部31为柔性导电线或者导电弹力包缠纱，柔性导电部31通过成圈、添纱或者衬垫的方式织入本体10。
传导部还包括连接线，柔性导电部31通过连接线与信号接收部电连接，进一步的，还可以分析校准系统电连接。
本实施例通过柔性导电部31作为传导部的主要部分织入医用压力袜中，其容易弯曲变形，且材质细、有弹性，不仅满足了穿着者对于舒适度的要求，还能够承受低机械阻力，易于穿脱、吊挂且耐用。因此，同时满 足了穿着和压力检测的要求，并且，其易于生产制造。
传导部的数量可为一个或多个，其设置于本体10的一个或多个位置，从而对相应位置的压力进行实时监测。如图5所示，传导部可位于B、B1、C的位置，可根据RAL-GZ 387/1及FTTS-FP-148标准定义设置传导部的数量和排布，传导部可沿着长度方向对齐且间隔的设置，可位于医用压力袜的下肢的内侧、外侧、前侧和/或后侧。
图11为医用压力袜的多个位置的压力分布示意图，其中，横坐标表示下肢的不同位置，纵坐标表示压力，A1至A3分别为三种医用压力袜的上述关系曲线，即，A1为普通针织结构，A2为集圈形式的针织结构，A3表示具有毛圈的集圈形式的针织结构。根据图11可知，在下肢的远离内踝的位置，上述三种针织结构施加的压力大致相同，而在内踝的位置，应用具有毛圈的集圈形式的针织结构施加的压力明显大于其他两种结构，且内踝压力与下肢其他位置的压力非常接近，即压力差较小，实现了整个下肢的压力均匀分布。
综上所述，本发明是在医用压力袜的下肢脚踝处一体的集成有辅助压力部，穿着时，辅助压力部能够适当的填补内踝与胫骨之间的空洞区，补偿此部分的压力，使得来自压力袜的压力传递给脚踝，因此脚踝的压力均匀，从而能够优化腿部，特别是脚踝的压力分布，避免静脉功能不全的患者于发生溃烂。并且，由于辅助压力部与本体集成为一体，二者不可分割，因此，在穿着及穿脱过程中，辅助压力部均不会相对于本体发生移位，能够始终保持在对应于下肢脚踝处的位置，因此，保证了使用的准确性和便利性。
并且，医用压力袜还集成有压力感测部，从而能够实时测量医用压力袜施加于腿部的压力，且测量值具有极高的准确性和可靠性，因此，有助于穿着者对于医用压力袜的舒适性进行监控。
虽然已参照几个典型实施例描述了本发明，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施例不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所 涵盖。
