Description

膀胱冲洗监控设备及其监控方法 技术领域：
本发明属于医疗器械技术领域，特别涉及一种膀胱冲洗监控设备，还涉及该设备配套的监控方法。
背景技术：
持续膀胱冲洗是利用导尿管，将溶液灌入到膀胱内，再藉用虹吸原理将灌入的液体引流出来的方法；临床上膀胱清洗主要用于以下几个目的：1、对留置导尿管的病人，保持其尿液引流通畅；2、清除膀胱内的血凝块、粘液、细菌等异物，预防感染的发生；3、治疗某些膀胱疾病，如膀胱炎、膀胱肿瘤。
如膀胱内出血较多、时间长，就需要大冲洗量及长时间的持续膀胱冲洗,为了盛装大量的冲出液，许多医院使用大容积敞口容器或集尿袋来收集冲出液。且为了观察冲洗通畅情况,常常将尿袋末端的开关松开,通过冲洗管路滴管内的滴速与尿袋末端的滴速是否一致来判断冲洗是否通畅,而事实上滴速的肉眼观察的准确性并不科学。而尝试用精密尿量器虽实现密闭冲洗，但操作仍显繁琐。如果冲洗期间要记录尿量，需用量杯来计量冲出液，该计量操作过程存在含有患者血液、尿液的冲洗液污染环境的风险。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容：
本发明的目的在于提供一种自动监控膀胱冲洗质量的膀胱冲洗监控设备，从而克服上述现有技术中的缺陷。
为实现上述目的，本发明提供了一种膀胱冲洗监控设备，设在尿滴管上，尿滴管的一端插入尿存储袋，其另一端插入患者膀胱内，尿滴管上设有流速监 控装置和负压抽吸计量装置，负压抽吸装置通过三通切换阀连通尿滴管，流速监控装置和负压抽吸装置通讯连接自动控制器，自动控制器还连有报警装置，所述。
一种膀胱冲洗监控设备，设在尿滴管上，尿滴管的一端插入尿存储袋，其另一端插入患者膀胱内，在尿滴管上设有流速监控装置和正压冲洗计量装置，正压冲洗计量装置通过三通切换阀连通尿滴管，流速监控装置和正压冲洗装置通讯连接自动控制器，自动控制器还连有报警装置。
本发明进一步限定的技术方案为：
优选地，上述技术方案中，负压抽吸装置或者正压冲洗计量装置装配在流速监控装置上游的尿滴管上。这是为了确保负压抽吸或者正压冲洗时，不会对流速监控装置产生干扰。
优选地，上述技术方案中，自动控制器上连有输入键盘，这是为了方便监控方法中特定参数的输入。
优选地，上述技术方案中，报警器为蜂鸣报警器。
优选地，上述技术方案中，流速监控装置为液滴流速检测装置或者流速仪，可以通过液滴或者流速来监控，流速数据能够快速计算获得单位时间内的尿排出量。
一种膀胱冲洗监控方法，按照如下步骤进行：
S1,尿滴管连通流速监控装置，三通切换阀此时为尿滴管上下连通且尿滴管不连通负压抽吸计量装置或者正压冲洗计量装置；
S2,设定一个流速标准值S 0，临界值a，流速监控装置实时检测流速S n，当|S n–S 0|≤a，则将当前流速记录在数集1中，n为正整数，否则进入S5；
S3,将数集1中的若干个流速值求平均值获得S avg，
S4,实时检测流速S n，当|S n–S avg|≤a，则将当前流速记录在数集1中并重复S3，否则进入S5，数集1重复步骤S3；
S5,尿滴管连通流速监控装置，三通切换阀此时为尿滴管上下不连通且尿滴管连通负压抽吸计量装置或者正压冲洗计量装置；设定一定体积的负压抽吸 量或者正压冲洗量，负压抽吸计量装置将预设体积的液体从尿滴管中抽出，或者正压冲洗计量装置将预设体积的液体反向注入尿滴管中；
S6,重复步骤S1和S4，如仍需进入步骤S5,则报警通知工作人员处理。
需要说明的是：自动冲洗一般只能进行一次，防止对患者的身体造成伤害。
本发明进一步限定的技术方案为：
优选地，上述技术方案中，所述流速标准值S 0，临界值a根据导尿管型号设定。
优选地，上述技术方案中，负压抽吸量或者正压冲洗量根据患者的膀胱容积设定。
优选地，上述技术方案中，进行步骤S5前，需要超声扫描获得患者膀胱的容积。
与现有技术相比，本发明具有如下有益效果：
实现了自动监控冲洗效果，避免了护理人员的看护工作量，另外由于可以直接获得单位时间内的流速值，那就可以很轻松的计算出单位时间内的排尿量。
