Description

一种能控制负压输入的封闭引流装置用控压阀
技术领域
本发明涉及一种能控制负压输入的封闭引流装置用控压阀，属于医疗设备技术领域。
背景技术
负压封闭引流技术(VSD)是指用内含有引流管的医用海绵敷料，来覆盖或填充皮肤、软组织缺损的创面，再用生物半透膜对之进行封闭，使其成为一个密闭空间，最后把引流管接通负压源，通过可控制的负压来促进创面愈合的一种全新的治疗方法。
其特点是：可控制的负压，促进血流量增长和蛋白合成，促进肉芽生长，加快创面愈合；同时为全方位的主动引流提供了动力。生物半透膜的封闭，隔绝了创面与外环境接触的感染机会。全方位的引流，是将传统的点状或局部引流，变为了面状引流，保证了能随时将创面的每一处的坏死组织和渗出物吸出。
现有的负压封闭引流技术在治疗时，负压源可能会因为意外情况停止，此时若不及时关闭冲洗液的输入，会导致冲洗液堆积在密闭空间内，轻则导致整个负压封闭引流需要重新更换，重则导致伤口进一步感染，加重病情；并且，负压源输入的负压也不能过大，会导致患者伤口处不舒服。
发明内容
为了解决上述现有技术中存在的问题，本发明提供一种能控制负压输入的封闭引流装置用控压阀，根据封闭引流装置内部的气压状态运行，当封闭引流装置内部解除负压状态时，能够防止冲洗液进入封闭引流装置影响伤口恢复，当负压源输入的负压过大时，能够减小进入封闭式引流装置的负压。
本发明的技术方案如下：

进一步的，所述第二通道包括第一腔体、第二腔体以及复数个连通所述第一腔体和第二腔体的流通管道，所述进气口与所述第一腔体连通，所述柱塞设置于所述第一腔体内，所述第二腔体与所述出气口连通；各所述连通管道上下间隔布置在所述第一腔体和第二腔体之间。
进一步的，所述阀体包括可拆卸连接的上阀体和下阀体；所述上阀体中空设置且下端开口，所述活动件设置于所述上阀体内，所述进水口和出水口开设于所述上阀体的外壁上；所述下阀体中空设置且上端开口，所述弹性件一端与所述活动件固定连接，另一端与所述下阀体的内壁固定连接，所述进气口、出气口和监测口的外壁上。

实施例一
参见图1和图2，一种能控制负压输入的封闭引流装置用控压阀，包括阀体1，所述阀体1中部开设空腔，所述空腔内活动设置有一活动件2，所述活动件2将所述空腔上下分隔为上腔和下腔；所述阀体1的外壁上开设有与上腔连通的进水口31和出水口32以及与所述下腔连通的进气口33、出气口34和监测口35；所述上腔内设置有连通所述进水口31和出水口32的第一通道101，所述活动件2的上端固定连接有止水杆21，所述止水杆21的上端设置于所述第一通道101内，且所述止水杆21的外侧壁上固定套设有密封圈22；所述下腔内设置有连通所述进气口33和所述出气口34的第二通道102，所述活动件2的下端固定连接有连接杆，所述连接杆的底部延伸至所述第二通道102内且固定连接有一柱塞20；所述监测口35的外端与封闭引流装置的内部连通，常态下，所述止水杆21通过密封圈22封堵所述第一通道101，当封闭引流装置的内部为负压状态时，活动件2向下腔活动，带动止水杆21移动并开放所述第一通道101，带动所述柱塞20移动并根据负压大小增加或减小第二通道102内的通气阻力。
进一步的，所述第二通道102包括第一腔体、第二腔体以及复数个连通所述第一腔体和第二腔体的流通管道103，所述进气口33与所述第一腔体连通，所述柱塞20设置于所述第一腔体内，所述第二腔体与所述出气口34连通；各所述连通管道103上下间隔布置在所述第一腔体和第二腔体之间。
进一步的，所述活动件2的下端与一弹性件4的一端固定连接，所述弹性件4的另一端与所述下腔的内壁固定连接；
进一步的，所述弹性件4为弹簧。
本实施例的工作原理如下：
在使用时，将控压阀设置于外部冲洗液输入源、外部负压源和封闭引流装置之间，使进水口31与外部冲洗液输入源连通，出水口32与封闭引流装置的冲洗导管连通，进气口33与外部负压源的输出口连通，出气口34与封闭引流装置的负压输入口连通，监测口35外端通过导管与封闭引流装置内部空间连通；当外部负压源工作时，封闭引流装置内部空间处于负压状态，通过监测口35，将活动件2向下腔吸引，外部冲洗液输入源输入的冲洗液能通过进水口31、第一滑道101、出水口32连通冲洗导管，使冲洗液进入封闭引流装置内；当外部负压源停止运行时，封闭引流装置内部解除负压状态，活动件2在弹性件4的作用下回弹，推动止水杆23封闭进水口31与出水口32之间的通道10，防止冲洗液进入封闭引流装置；
当外部负压源输入的负压过大时，活动件2大幅度下移，带动柱塞20向下移动，封堵若干个连通管道103以增大第二通道102内的通气阻力，减小输入至封闭引流装置中的负压大小，保持封闭引流装置中的负压大小相对恒定，防止输入至封闭引流装置中的负压过大导致患者不适。
实施例二：
本实施例与实施例一的区别之处在于，所述阀体1包括可拆卸连接的上阀体11和下阀体12，上阀体11和下阀体12可以通过螺纹连接或者卡扣连接；所述上阀体11中空设置且下端开口，所述活动件2设置于所述上阀体11内，所述进水口31和出水口32开设于所述上阀体11的外壁上，在本实施例中，进水口31开设在上阀体11的顶部，出水口32开设在上阀体11的侧方；所述下阀体12中空设置且上端开口，所述弹性件4一端与所述活动件2固定连接，另一端与所述下阀体12的内壁固定连接，本实施例中，所述进气口33开设于所述下阀体12的底部，出气口34靠近进气口33开设于下阀体12的侧壁，监测口35开设于下阀体12中部的侧壁上。
本实施例将阀体设置为可拆卸连接的上阀体11和下阀体12，安装、替换和维修容易。
实施例三
作为优选，本实施例将活动件2设置为弹力膜23、连接固定件24和膜压片25三个部件组成；所述弹力膜23水平设置于所述空腔内，所述连接固定件24固定穿设于所述膜压片25的中部，所述止水杆21的底端垂直穿设入所述连接固定件24内部与所述连接固定件24固定连接；所述连接杆的顶端垂直穿设入所述连接固定件24内部与所述连接固定件24固定连接；所述膜压片25固定套设于所述连接固定件24的下端部，且所述膜压片25的顶部与所述弹力膜23固定连接。
本实施例的工作原理如下：
当封闭引流装置内部处于负压状态时，将弹力膜23向下腔吸引，弹力膜23中部在负压作用下移动，通过膜压片25和连接固定件24拉动止水杆21并推动柱塞20，使进水口31与出水口32之间的通道10连通，使柱塞20活动控制第二通道102中的通气阻力；当封闭引流装置内部解除负压状态时，膜压片25在弹性件4的作用下回弹，带动止水杆21封堵进水口31和出水口32之间的通道10，带动柱塞20回到原位，使第二通道102中的通气阻力回到常态。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
