Description

[根据细则26改正21.09.2015]　一种桡动脉加压压迫止血装置 技术领域
本发明涉及一种医疗止血器，具体涉及一种作用于桡动脉的一次性压迫止血器，属于医疗器械技术领域。
背景技术
介入手术已经是心脏内科、神经内科等医疗科室的常规治疗手段，介入手术的优点在于医生可在不使用全身麻醉剂或不需要开刀手术的情况下进入患者身体内进行治疗。通常情况下，介入诊断和治疗的手术，尤其是心脏内科的介入手术，是通过患者的桡动脉通路来实现的，桡动脉通路的介入手术具有并发症少、患者卧床限制活动是时间短，治疗费用低等优点，但同其它的动脉穿刺的手术一样，术后的动脉完全止血是介入手术后防止穿刺点出血的重要一环。
通常介入手术完成，导管去除后，由医生或医疗专业人员在动脉导管穿刺点处施加压力以实现止血和动脉穿刺点的闭合，止血和动脉穿刺点闭合需要持续稳定的压力，一般初期给予的压力较高，经过一段时间后，需要逐渐降低压力，使血管下游组织得到丰富的血供。目前桡动脉穿刺点止血主要通过人工止血或机械加压设备加压止血，人工止血通过医护人员手工按压或施加绷带加压止血，此种方法极耗费医护人员体力和时间；现有的机械加压设备一般通过气囊或者旋钮进行充气或者推进加压，可以减轻医护人员的体力消耗，提高止血效率，但该类设备存在2个显著问题，一是止血效果较差，止血成功率没有人工止血高，渗血情况较多；二是由于手臂受到较大的压迫力使得静脉回流受阻，从而导致手部以及手臂肿胀、发紫，增加了患者的不适与恐慌感。
发明内容
本发明的目的在于解决现有技术的不足，并提供一种止血效率高并且可减轻手臂所受压迫力的止血装置。
实现本发明目的所采用的技术方案为，一种手臂减压型桡动脉加压止血装置，包括减压单元和止血单元，减压单元包括减压支撑板和2条以上固定在减压支撑板上的固定带，减压支撑板呈长条状，上表面的形状与手臂前臂背面的解剖结构相吻合，上表面的中部沿长边设有支撑脊，支撑脊的两侧设有与桡骨和尺骨形状相匹配的凹形结构，减压支撑板沿长边向下弯曲呈弧形，固定带位于减压支撑板同一长侧边；所述止血单元包括压板，与压板两端连接的连接带，固定在压板外侧面上的螺母，穿过压板并且与螺母螺纹连接的螺杆，以及固定在 螺杆底面上的压迫垫，压迫垫位于压板下方，压迫垫的底面上设有止血敷料层，止血单元通过压板和连接带套设在减压支撑板上，压板位于减压支撑板的上方，固定带位于止血单元的两侧，压板的下表面上设有下表面上设有柱状的柔性固定垫。
所述压板呈长条状，压板位于螺杆两侧的部分形成两个侧翼，两个侧翼的长度不相等，柔性固定垫固定在长侧翼的下表面上。
所述压板沿长边向下弯曲呈弧形，压板两个侧翼的端部均设有带孔，连接带的一端固定在其中一个带孔中，另一端为粘扣带，粘扣带穿过另一个带孔并且粘固。
所述压板上设有手持座，手持座位于螺母与压板之间，手持座呈圆台状并且为中空结构，圆台状手持座的两条相对的母线处设有防滑凸起。
压板与螺杆之间设有连接套，连接套呈中空圆筒状，连接套通过卡扣与螺杆连接，螺杆通过连接套固定在压板和手持座中。
所述减压支撑板沿宽边向上弯曲呈弧形，弧形与手臂前臂背面的弧形相吻合。
所述固定带设有两条，两条固定带位于减压支撑板同一长边的两端，减压支撑板的另一长边上设有两个与固定带位置相对的孔扣，固定带上开设有2个以上与孔扣相匹配的扣孔。
所述压迫垫与柔性固定垫均为硅胶垫。
与现有技术相比，本发明的有益效果为：
1、止血单元固定在手腕上后，通过调节螺杆可为穿刺点提供连续、可调的压力，从而实现压迫止血，压板内侧面上设有用于辅助支撑螺杆的柔性固定垫，增大止血单元与手腕的接触面积，增加止血单元的稳定性，压板上的手持座可在拔管或压迫止血时固定止血单元，防止误碰止血单元造成压迫垫错位；
2、止血敷料层料通过关联专利CN201210545888.8制备而成，压迫止血时敷料层直接接触穿刺口，复合止血敷料层的压迫垫能够更好的封闭创口与穿刺通道，减少渗液和穿刺点出血的发生几率；
3、减压支撑板的两个凹形结构可适应前臂背部的桡骨和尺骨，避免对较硬的骨结构以及伴行的静脉产生压迫，支撑脊可接触手臂背部的软组织，提供支撑力度，以上结构可更好的适应前臂背部的解剖结构，减压支撑板沿宽边向上弯曲呈弧形，弧形与手臂前臂背面的弧形相吻合，便于将减压支撑板固定在手臂前臂上，使减压支撑板与前臂有效贴合，减压支撑板与前臂背部有较大接触面积，可以显著分散压迫力，从而减少止血装置对静脉的压迫，不影响血液回流；减压支撑板具有较好的弧度曲线，可以在手术前固定于病人手腕部，从而提供较好的手术姿势，暴露动脉血管位置。
