[0023] 图 2为根据本发明的实施例的压迫止血装置的背面的结构示意图。
本发明的实施方式
[0024] 为使本发明的目的、 技术方案和优点更加清楚明白, 以下结合具体实施例并参 照附图对本发明进一步详细说明。
[0025] 本发明提出一种压迫止血装置, 提供具有通透光路的结构, 能够更清楚地观察 出血病情并根据患者病情更有效地压迫止血。
[0026] 根据本发明的实施例, 提供一种压迫止血装置, 包括:
[0027] 基体;
[0028] 束带, 其两端分别连接到所述基体的两端而构成环形;
[0029] 压迫机构, 其设置在所述基体的朝向所述束带的内侧上, 包括压迫腔和压迫件 , 所述压迫件以一可动部可动地密封所述压迫腔且在朝向所述束带的压迫端设 置有透明镜片, 所述基体至少部分透明以形成从所述透明镜片穿透所述基体的 通透光路;

[0031] 这样, 当调节件的运动使调节腔的容积变化 (例如变小) 吋, 由于调节腔与压 迫腔连通, 因而使二者构成的流体腔的容积变化 (例如变小) , 由此使流体腔 中的压力相应变化 (例如变大) , 这种流体压力的变化传递到密封压迫腔的压 迫件上, 使得压迫件 (在其压迫端) 上的压力相应变化 (例如变大) , 由此以 更大的压迫力作用于患者出血部位进行压迫止血操作。 反之亦然, 也可以相应 地降低压迫止血的压力。 由调节机构施加的压力变化传递到与患者出血部位直 接接触的压迫件的压迫端, 由此实现压迫止血压力的调节。 [0032] 这样的压迫止血装置, 不需要外接气体或液体源来提供操作压力, 而是在相对 封闭的体系中实现压迫止血压力的调节, 不仅结构紧凑尺寸小, 而且操作方便
[0033] 特别注意的是, 基体至少部分透明, 形成从透明镜片经压迫机构的主体结构而 穿透基体的通透光路, 使得医务人员能够更清楚地看到压在透明镜片下的患者 出血点处的情况, 从而更有利于针对出血点的最新情况作出准确的判断和处理 , 使得压迫止血操作更加安全可靠。
[0034] 在此所述的在基体与束带之间的"连接", 可以是在其两端均被可松脱地连接, 也可以是在其中一端被可松脱地连接而在另一端则固定连接, 这都在本发明的 保护范围内。
[0035] 在此所述的基体与束带构成的"环形", 是指在所述压迫止血装置的操作就位状 态下所构成的形状, 此吋, 基体与束带分别在两端连接完毕, 使患者的身体 ( 例如肢体) 的出血点所在部分被保持在束带与压迫机构的压迫件的压迫端之间 。 由此, 所述压迫止血装置的全部或者至少大多数的组成部件均位于所述环形 的范围内, 在结构上紧凑而具有更小尺寸。 应理解, 所述环形是指整体上大致 呈环形, 而不限于严格的几何环形 (例如圆环形) 。
[0036] 在此所述的束带, 根据具体需要可具有不同的柔性和弹性。 例如, 束带可为具 有一定弹性的刚性束带, 或者可为完全柔性的软束带, 甚至还可以由刚性部分 和柔性部分结合而成。
[0037] 应理解, 所述压迫止血装置的流体腔中可根据需要采用气体或液体。 在较佳实 施例中采用空气作为填充于流体腔中的流体, 不仅可以避免由于液体渗漏所造 成的环境污染和复杂处理操作, 而且, 由于空气的弹性大于液体, 因而对压迫 止血压力的调节可以更加精细。
[0038] 优选地, 在本发明的各实施例中, 所述压迫件包括: 朝向所述束带延伸的压迫 缸体、 和能够在所述压迫缸体内滑动的压迫活塞, 所述压迫活塞作为所述可动 部在一端可动地密封所述压迫腔且在朝向所述束带的压迫端设置有所述透明镜 片。 这样, 当调节件的运动使调节腔的容积变化 (例如变小) 吋, 由于调节腔 与压迫腔连通, 因而使二者构成的流体腔的容积变化 (例如变小) , 由此使流 体腔中的压力相应变化 (例如变大) , 这种流体压力的变化传递到密封压迫腔 的压迫件上, 使得压迫件 (在其压迫端) 上的压力相应变化 (例如变大) , 由 此以更大的压迫力作用于患者出血部位进行压迫止血操作。 反之亦然, 也可以 相应地降低压迫止血的压力。 压迫活塞在压迫缸体内能够自由滑动, 从而将调 节机构施加的压力变化传递到与患者出血部位直接接触的压迫件的压迫端, 由 此实现压迫止血压力的调节。
[0039] 优选地, 在本发明的各实施例中, 所述压迫活塞的在所述压迫缸体内的部分的 外周上设置有环形密封圈。 这样, 可有助于密封压迫腔。 更佳地, 该环形密封 圈由硅胶制成。
[0040] 优选地, 在本发明的各实施例中, 所述压迫活塞具有圆形或非圆形 (例如矩形
) 的截面形状。
[0041] 优选地, 在本发明的各实施例中, 所述压迫缸体具有圆形或非圆形 (例如矩形
) 的截面形状。
[0042] 在一个实施例中, 压迫活塞或压迫缸体可具有椭圆形的截面形状。
[0043] 应理解, 本发明中所述的非圆形形状 (例如矩形, 特别是正方形) 是指整体形 状, 这种非圆形形状根据需要可具有尖角或圆角, 较佳地可采用具有四个圆角 的矩形形状, 圆角可减少元件碰撞受损的可能性。
[0044] 优选地, 在本发明的各实施例中, 所述透明镜片固定到所述压迫端或者与所述 压迫端形成为一体。
[0045] 优选地, 在本发明的各实施例中, 所述压迫活塞是中空的或者是实心透明的。
无论采用哪种方式, 均可确保从透明镜片经压迫活塞、 压迫腔至穿透基体的通 透光路, 由此使医务人员能够通过该通透光路直接观察到压在压迫活塞压迫端 处透明镜片下的出血点的情况, 从而采取有效的止血方式。
[0046] 在一个实施例中, 压迫活塞是全透明的结构。
[0047] 在一个实施例中, 压迫缸体是全透明的结构或部分透明的结构。
[0048] 在较佳实施例中, 整个压迫机构为全透明的结构。
[0049] 优选地, 在本发明的各实施例中, 所述调节件包括: 调节缸体、 能够在所述调 节缸体内滑动的调节活塞、 和驱动结构, 所述调节活塞作为所述可动体在一端 可动地密封所述调节腔且在另一端连接到所述驱动结构, 所述驱动结构的旋转 驱动所述调节活塞滑动而改变所述调节腔的容积。 这样, 当调节件的运动使调 节腔的容积变化 (例如变小) 吋, 由于调节腔与压迫腔连通, 因而使二者构成 的流体腔的容积变化 (例如变小) , 由此使流体腔中的压力相应变化 (例如变 大) , 这种流体压力的变化传递到密封压迫腔的压迫件上, 使得压迫件 (在其 压迫端) 上的压力相应变化 (例如变大) , 由此以更大压迫力作用于患者出血 部位进行压迫止血操作。 反之亦然, 也可以相应降低压迫止血的压力。 调节活 塞在调节缸体内能够自由滑动, 从而将调节机构施加的压力变化传递到与患者 出血部位直接接触的压迫件的压迫端, 由此实现压迫止血压力的调节。
[0050] 较佳地, 在本发明的各实施例中, 所述调节活塞的在所述调节缸体内的部分的 外周上设置有环形密封圈。 这样, 可有助于密封调节腔。 更佳地, 该环形密封 圈由硅胶制成。
[0051] 较佳地, 在本发明的各实施例中, 所述调节活塞具有圆形或非圆形 (例如矩形
) 的截面形状。
[0052] 较佳地, 在本发明的各实施例中, 所述调节缸体具有圆形或非圆形 (例如矩形
) 的截面形状。
[0053] 在一个实施例中, 调节活塞或调节缸体可具有椭圆形的截面形状。
[0054] 应理解, 本发明中所述的非圆形形状 (例如矩形, 特别是正方形) 是指整体形 状, 这种非圆形形状根据需要可具有尖角或圆角, 较佳地可采用具有四个圆角 的矩形形状, 圆角可减少元件碰撞受损的可能性。
[0055] 优选地, 在本发明的各实施例中, 所述驱动结构包括调节旋钮或者连接到驱动 齿轮。 这样, 驱动结构采用旋转驱动的方式 (例如由操作者旋转调节旋钮或者 由电机带动驱动齿轮) , 并以这种旋转运动带动调节活塞线性地滑动以改变调 节腔的容积。 在此将旋转运动转化为直线运动, 因此, 公知的是, 旋转较长距 离才能使调节活塞滑动一小段距离, 由此能够使对压迫止血压力的调节更加精 细, 因而压迫止血操作也更加安全可靠。
[0056] 在一个较佳实施例中, 沿调节旋钮的外周设置有刻度标记, 以利于更好地控制 调节操作。 [0057] 优选地, 在本发明的各实施例中, 所述调节机构安装在所述基体的一端处的安 装通孔中, 所述安装通孔的轴线穿过由所述基体和所述束带所构成的环形内, 所述调节旋钮位于伸出到所述安装通孔之外的驱动结构的部分上。 这样, 不仅 使所述压迫止血装置的结构更紧凑, 而且使调节旋钮处于基体的侧方, 既便于 调节操作, 又不会妨碍到医务人员对病情的观察, 特别是通过基体的透明部分 穿过压迫机构至透明镜片的通透光路对透明镜片下所压紧的出血点的观察。
[0058] 在一个实施例中, 安装通孔的轴线垂直于由基体和束带所构成的环形的平面 ( 即, 成 90度) 。 这样, 沿所述轴线安装的调节旋钮的延伸方向垂直于从基体朝 向束带延伸的压迫件的方向, 可避免调节操作干扰到压迫操作。
[0059] 在另一实施例中, 安装通孔的轴线倾斜于由基体和束带所构成的环形的平面 ( 即, 成小于 90度, 例如 75— 85度, 较佳地为 80度) 。 这样, 沿所述轴线安装的 调节旋钮可倾斜向上地处于安装通孔之外, 调节旋钮位置较高, 在某些应用环 境中更便于医务人员的调节操作。
[0060] 较佳地, 在本发明的各实施例中, 所述调节机构 (例如所述调节件) 可安装在 所述基体上或所述压迫机构上。
[0061] 在一个实施例中, 调节机构 (例如调节件) 安装在基体上并与压迫机构分幵适 合的距离, 从而不会使调节操作影响到压迫机构的压迫止血操作。
[0062] 在另一实施例中, 调节机构 (例如调节件) 也可安装在压迫机构上, 以进一步 使结构紧凑。 应理解, 由于调节腔与压迫腔连通, 因而二者实质上可视为一个 共同的流体腔, 因而调节机构安装在压迫机构上可直接对此流体腔进行操作以 改变此流体腔的容积以及内部压力, 从而实现对压迫机构压迫件处压迫止血压 力的调节。
[0063] 优选地, 在本发明的各实施例中, 所述透明镜片是凸透镜片。 这样, 从凸透镜 片经压迫机构的整体结构而穿透基体的通透光路, 使得医务人员能够更清楚地 看到压在凸透镜片下的患者出血点处的、 通过凸透镜片放大的放大图像, 从而 更有利于针对出血点的最新情况作出准确的判断和处理, 使压迫止血操作更加 安全可靠。
[0064] 优选地, 在本发明的各实施例中, 所述凸透镜片包括: 平坦的基片, 和在该基 片的中央向一侧外凸的凸透放大部分, 所述基片为圆形或矩形, 所述凸透放大 部分为圆形或矩形。 这样, 凸透镜片一侧平坦可压在患者出血点处, 另一侧的 凸透放大部分则在形状上匹配于压迫件的压迫端 (例如二者可均为圆形或非圆 形) 以固定到压迫端实现出血点图像放大功能。 基片的尺寸较大可具有与患者 出血点处皮肤的更大接触面积, 以利于固定和压迫止血, 基片的形状可根据需 要为圆形或非圆形 (例如矩形) 。 应理解, 本发明中所述的非圆形形状 (例如 矩形, 特别是正方形) 是指整体形状, 这种非圆形形状根据需要可具有尖角或 圆角, 较佳地可采用具有四个圆角的矩形形状, 圆角可减少基片边缘对患者接 触部位造成伤害的可能性。
[0065] 在一个实施例中, 基片的与患者皮肤接触的一侧的边缘可具有卷边, 以在进行 压迫止血吋更好地适应患者出血点处的压迫身体部分, 并可减少边缘造成伤害 的可能性。
[0066] 在一个实施例中, 所述透明镜片 (特别是所述基片) 是能够改变形状的弹性的 片, 以减少造成或者伤害的可能性。
[0067] 在一个实施例中, 所述透明镜片上设置有透明弹性垫, 即, 透明弹性垫与患者 皮肤直接接触, 以减少造成或者伤害的可能性。
[0068] 在一个实施例中, 束带是具有一定弹性的硬束带, 即, 能够产生一定的弹性变 形但整体上不是柔软的带子, 这样能够在艰苦应用环境中保护患者的身体 (例 如肢体) 。
[0069] 在一个实施例中, 束带是柔性束带, 能够容易地变形以更好地束紧患者的身体
(例如肢体) 。
[0070] 在一个实施例中, 束带的两端分别被可松脱地连接到基体的两端。
[0071] 在另一实施例中, 束带的一端固定连接到基体的一端, 束带的另一端被可松脱 地连接到基体的另一端。
[0072] 在一个实施例中, 基体在整体上为板形。
[0073] 在另一实施例中, 基体在整体上为弯曲的带形。
[0074] 图 1为根据本发明的实施例的压迫止血装置的正面的结构示意图。
[0075] 在图 1所示的实施例中可见, 压迫止血装置包括: [0076] 基体 100;
[0077] 束带 200, 其两端分别连接到所述基体 100的两端而构成环形 (在图 1中显示为 分别在左右两端连接) , 由此可将患者需要止血的部位 (例如肢体) 伸入这样 的环形中进行紧固以执行压迫止血操作;
[0078] 压迫机构 300, 其设置在所述基体 100的朝向所述束带 200的内侧 (在图 1中显示 为下侧) 上, 包括压迫腔和压迫件, 所述压迫件以一可动部 (例如所述压迫活 塞) (在图 1中以压迫活塞上端) 可动地密封所述压迫腔且在朝向所述束带 200 的压迫端 (在图 1中为下端) 设置有透明镜片 301, 所述基体 100至少部分透明以 形成从所述透明镜片 301穿透所述基体 100的通透光路 (在图 1中以从下向上的箭 头 A指示出从透明镜片 301穿过压迫机构 300的主体和基体 100的通透光路) ;
[0079] 调节机构 400, 其包括调节腔和调节件, 所述调节腔连通所述压迫腔, 所述调 节件以一可动体 (例如所述调节活塞) 可动地密封所述调节腔, 所述调节件的 运动改变所述调节腔的容积而改变经由所述压迫腔传递到所述压迫件的压力。
[0080] 在图 1中还显示出调节机构 400的调节件的驱动结构 401, 在图 1所示的实施例中 , 驱动结构 401可包括调节旋钮, 由此采用旋转驱动方式 (例如由操作者旋转调 节旋钮) 将旋转运动转化为相关部件 (例如调节活塞) 直线运动 (在图 1的实施 例中可为沿垂直于纸面方向的直线运动) 以改变调节腔的容积, 进而可以改变 经由所述压迫腔传递到所述压迫件的压力 (在图 1的实施例中可为向下压迫患者 出血点的压力) 。 由此通过这种从旋转运动向直线运动的转化, 使得压迫止血 压力的调节更加精细, 因而压迫止血操作也更加安全可靠。
[0081] 另外, 特别重要的是, 形成了从透明镜片 301穿过压迫机构 300的主体和基体 10 0的通透光路, 如图 1中的箭头 A所示。 其中应理解, 压迫机构 300的主体 (例如 其中的压迫活塞) 应至少部分透明, 以保证通透光路不受阻碍 (较佳地, 压迫 活塞整个都是透明的) 。 这样, 医务人员能够通过该通透光路直接观察 (例如 在图 1中所示字母 A处观察) 到压在压迫活塞压迫端处透明镜片 301下的出血点的 情况, 从而采取有效的止血方式。 特别有利的是, 透明镜片 301可包括或者可以 是凸透镜片, 由此提供放大图像, 更有利于看清出血点的情况。
[0082] 图 2为根据本发明的实施例的压迫止血装置的背面的结构示意图。 [0083] 图 2所示的实施例与图 1所示实施例类似, 不过, 从背面无法看到所述压迫止血 装置的调节件 (例如图 1中所示的采用调节旋钮形式的驱动结构 401) 。
[0084] 通过本发明各实施例所述的压迫止血装置, 提供具有通透光路的结构, 能够更 清楚地观察出血病情并根据患者病情更有效地压迫止血。
[0085] 本发明中提供的各个实施例均可根据需要而相互组合, 例如任意两个、 三个或 更多个实施例中的特征相互组合以构成本发明的新的实施例, 这也在本发明的 保护范围内, 除非另行说明或者在技术上构成矛盾而无法实施。
[0086] 本发明所属领域的普通技术人员应当理解: 以上所述仅针对本发明的具体实施 例而已, 但不用于限制本发明的范围, 凡在本发明的精神和原则之内所作的任 何改进、 变化、 等同替换等, 均应包含在本发明的保护范围之内。
