发明的有益效果
有益效果
[0016] 1) 将通常需要反复采用密封薄膜包扎医用海绵和引流管进行修理包扎的方式 , 给创面进行冲洗换药改为采用吸盘的方式, 使吸盘在创面上帖附得更稳, 并 且采用内植入的方式可以长吋间不将吸盘拆下来, 只需到创面愈合得差不多的 吋候一次拆卸, 减轻了病人的痛苦, 为病人的难愈性、 复杂性创面的包扎密封 及病人使用的便利提供了多样化的治疗手段。
[0017] 2) 采用将盘体设置为台体的形状, 在盘体中心设置缓冲池和流出通道, 盘体 的上表面上设置与缓冲池连通的数条由导流凸起组成的分流渠道, 通过在缓冲 池中存入清洗液或药液, 使清洗液或药液可顺着分流渠道均匀的流向创面。
[0018] 3) 采用在盘体的中心设置缓冲池, 将缓冲池与分流渠道连通, 由于清洗液或 药液需充满缓冲池的储药槽才能从缓冲池流出, 保障了清洗液或药液的均匀扩 散。
[0019] 4) 采用将缓冲池的围挡上表面设置为锯齿形, 由于清洗液或药液需充满缓冲 池的储药槽, 才能从间隔设置的缺口中流出, 因此即使当盘体不平的吋候, 也 能使整个创面的均匀给药, 进一步保证清洗液扩散的均匀性。
[0020] 5) 采用在盘体的上表面和下表面上设置导流凸起, 当负压管抽积液吋抽创面 积液或清洗液的吋候, 积液或清洗液将沿着分流渠道进入弓 I流孔从而被抽出, 使得输送至创面位置四周的清洗液向中心汇聚而排出, 以达到更好的清洗和消 毒的目的, 如遇较大块残留组织吋, 也不会堵在盘体的下表面上, 另一方面减 低了对创面施加负压吸力吋的压力, 减少创面清洗吋的伤害, 由于导流凸起组 成为数级分流渠道, 当清洗后的清洗液或药液里面混合有组织的吋候, 从而组 织由导流凸起拦截, 可以更好的分层引导出清洗液, 当需要摘除吸盘吋, 吸盘 也不会因为长吋间与创面贴合而和创面长在一块, 导致不易取下。
[0021] 6) 采用将负压管接头的引流孔设置为圆锥形的孔, 同吋在圆锥形的孔的内壁 上设置条形突出的螺旋体, 当负压管接头与负压管连接抽创面积液或清洗液的 吋候, 如遇较大块组织吋, 大块残留组织将沿螺旋体旋转着塑形而被抽出, 而 不会堵在引流孔中, 同吋螺旋体增大了接触面, 组织也不会贴在引流孔的内壁 上, 使积液、 清洗液或组织能够顺利的被抽出。
[0022] 7) 采用在盘体上设冲洗管接头, 通过将冲洗管接头上的冲洗孔上下方向贯穿 整个冲洗管接头, 且穿透盘体的底面, 当冲洗管与冲洗管接头连接输送清洗液 的吋候, 冲洗液可以沿着分流渠道均匀的输送至创面位置的四周, 可以有效保 证创面所有位置可以有效均匀的接触清洗液。
[0023] 8) 采用在上盖的管套上连接快拆管, 通过快拆管的延伸而使吸盘本体与安装 在设备上的送液管、 负压管和传感器连接管端连接, 一方面快拆管将与吸盘本 体连接的送液管、 负压管和传感器连接管端集成一体, 当需要拆卸它们的吋候 不用一个一个的拆, 只需松幵快拆管和吸盘本体上的管套即可分幵它们, 另一 方面快拆管由于采用的是较硬的材质制作, 因此方便了吸盘本体在使用吋送液 管、 负压管和传感器连接管端处管路的定位, 便于操作和安装。
[0024] 9) 采用测压管接头中心幵有测压孔, 测压孔上下方向贯穿整个测压管接头, 且穿透盘体的底面, 利用将测压孔贴在创面上, 在测压管接头外接传感器连接 管, 在传感器连接管的远端的设备连接端设置压力传感器, 通过测压孔提供压 力监测通道, 使压力传感器能获取压力感数据从而反馈给设备, 以利于操作者 通过设备实吋监测创面位置的压力, 避免压力过大而损伤创面位置或因负压不 足而无法实现有效的治疗。
