Description

一种对排出的透析液的自动检测方法、装置 An automatic method for detecting a dialysate discharged, means

技术领域 FIELD

[0001] 本发明涉及医疗设备领域,尤其涉及一种对排出的透析液的自动检测方法、装置。 [0001] The present invention relates to the field of medical devices and more particularly, to a dialysate discharged from the automatic detection method, apparatus.

背景技术 Background technique

[0002] 腹膜透析技术是类似于人工血液净化的变型方式。 [0002] Peritoneal dialysis is similar to the artificial variant of blood purification. 其是通过利用患者的供血良好的腹膜作为身体自身的过滤膜。 Which is good by using the patient's blood the body's own peritoneum as a filtration membrane. 将透析液通过导管输入至患者的腹腔,根据渗透原理,尿液成分被从血液中排除并进入腹腔。 The dialysate is input to the patient's abdominal cavity via a catheter, in accordance with the principle of osmosis, the urine components are removed from the blood and into the abdominal cavity. 数小时之后,然后将该携带该尿液成分的透析液从腹腔排出,从而实现透析的效果。 After several hours, the dialysate is then carried from the abdominal cavity of the component of urine is discharged, thereby achieving the effect of dialysis.

[0003] 在现有的技术中,一般可以采用几种不同的方法来进行腹膜透析。 [0003] In the prior art, several different general methods can be employed to carry out peritoneal dialysis. 例如,对于持续性非卧床腹膜透析(CAPD),患者自己可以手动更换透析液,例如,每天可以更换4至5次透析液即可;而对于自动化腹膜透析(APD),一种被称作循环仪(Cycler)的设备可在夜间实现自动更换透析袋,从而使患者在白天不会受到限制。 For example, for continuous ambulatory peritoneal dialysis (of CAPD), a patient may himself manually replace the dialysate, for example, four to five daily replacement can dialysate; for automated peritoneal dialysis (the APD), what is known as loop instrument (Cycler) device can automatically replace the dialysis bag at night, in the daytime so that the patient will not be restricted.

[0004] 在这种自动化腹膜透析中,腹腔通过循环仪被填充透析液,填充容量需要控制,给患者提供最大填充量对于普通成人而言例如是3500ml左右。 [0004] In such automated peritoneal dialysis, dialysis fluid through the peritoneal cavity is filled cycler, need to control the fill volume, the maximum filling amount provided to a patient for normal adults, for example, approximately 3500ml. 通常,会采用一个标准值用作填充量,可以避免通过试验来确定每一患者所特有的填充量所带来的复杂工作。 Typically, a standard value will be used as filling amount, to avoid the complex work to determine each patient specific filling amount caused by the test.

[0005] 通常,在腹膜透析仪中,通过一个插入患者腹腔的导管来输入透析液,即,所谓的患者导管,通过患者导管来实现液体交换。 [0005] Generally, in the peritoneal dialyzer, input by a catheter inserted into the patient's abdominal cavity dialysis fluid, i.e., a so-called patient conduit, is achieved through the patient fluid exchange catheter. 导管的一端通入患者腹腔,另一端(在患者体外)设有患者用连接器,其提供连接到软管系统的可能性。 One end of the catheter into the abdominal cavity, the patient and the other end (outside the patient) is provided with a patient connector, which offers the possibility to connect to a hose system.

[0006] 在腹膜透析中,透析溶液被填充入患者腹腔中,通过患者腹膜在透析液和血液之间发生物质交换。 [0006] In peritoneal dialysis, a dialysis solution into the patient's abdominal cavity is filled, the material exchange occurs between the blood and dialysate through the patient's peritoneum. 在一定停留时间后,已经使用过的透析液被后续提供的新鲜透析液替代。 After a certain residence time, fresh dialysis fluid has been used dialysate is provided subsequent replacement. 用过的透析液被排出至回收袋中。 Spent dialysate is discharged to the recovery bag. 由于在体内经过腹膜透析作用,排出的透析液颜色会发生改变。 Since the effect in vivo after peritoneal dialysis, the dialysate is discharged will change color. 除了透析液变色外,还常常发生透明度上的变化,即排出的透析液可能变得混浊。 In addition to the dialysate color, transparency changes often occur, i.e., the dialysate discharge may become cloudy. 在使用前,透析液的颜色一般为类似苹果汁的颜色;而使用后,透析液会发生相应的变色或者浑浊。 Before use, the color of the dialysate is generally similar to the color of apple juice; and after use, the dialysate accordingly discoloration or occurrence of turbidity. 医生、负责透析的人员或者患者本人可以通过目测检查使用后的透析液是否具有常见的正常变色。 The doctor, who is responsible for dialysis patients or whether I can have a common normal color dialysate through the use of visual inspection. 如果出现的颜色异常,则患者可能会有一定的健康风险,例如蛋白质分泌增加、血分泌增加,很可能是早期腹膜炎的表征。 If the color appears abnormal, the patient may be some health risks, such as protein secretion, increase blood secretion, it may be an early peritonitis characterization. 因此,当出现颜色异常时,需要进一步的检查找出原因,以免给患者带来健康风险。 Therefore, when the color is abnormal, you need further examination to find out why, so as not to pose health risks to the patient.

[0007] 在图1中示意地示出了现有技术中通过人工对比确定当前排出的透析液的颜色以及透明度/混沌。 [0007] In FIG 1 schematically illustrates a prior art discharge current is determined by comparison of the dialysate artificial color and opacity / chaotic. 具体的,其技术方案为设置一段用于放置排除透析液的试样的透明透析管22',用于观察混浊颜色的部位设置有背光照亮区20',以降低由环境造成的误差。 Specifically, the technical scheme provided for placing the negative period of the transparent sample dialysate dialysis tube 22 ', for the color turbidity observed region illuminated region 20 is provided with a backlight', in order to reduce errors caused by the environment. 同时在右侧设置有可以选择的预设参考样本及其对应显示面板12',对应的,设置有可以选择参考样本的调节按钮14'。 While the right side is provided with a preset reference samples may be selected and the corresponding display panels 12 ', corresponding to the reference sample can be selected provided with a regulating button 14'. 在实际使用的时候,通过手动调节调节按钮14',并通过观察来调用和试样最接近的参考样本。 In actual use, by manually adjusting the adjustment button 14 ', and to call the nearest sample and reference samples by inspection. 当确定了和试样最接近的参考样本后,参见图2,将当前确定的颜色存储在设备的存储芯片内,供治疗使用。 When the sample is determined and the closest reference samples, see FIG. 2, the memory chip in the device, for treatment with the currently determined color storage.

[0008] 但是,现有技术也存在不足之处:因为参考样本的选择是人工进行操作的,而且试样颜色的识别也是通过人工观察实现的。 [0008] However, the prior art there are also disadvantages: because the choice of reference sample is manually operated, and the color of the sample is identified by human observation is realized. 故这种方式自动化程度低,在没有操作人员以及患者休息的情况下,就无法获得透析液相关的信息。 Therefore, the low degree of automation in this way, in the absence of the operator as well as the rest of the patient can not get dialysis fluid relevant information. 并且,实际治疗过程是长时间的持续治疗以及大量的夜间治疗,因此很多情况下,无法对透析液的混浊颜色进行检测。 Moreover, the actual treatment process is continuing treatment for a long time and a large number of nighttime treatment, so in many cases, can not turbid color dialysate for testing. 而且,不同时间排出的透析液的混浊颜色也可能有很大的差别,例如开始阶段排出的颜色较深,而后面排出的颜色较浅,那么人工测量的频率不够时则无法获得全面的关于排出的透析液的状态息。 Moreover, turbid color dialysate discharged at different times may vary considerably, for example, the darker the beginning of discharge, and discharged back lighter in color, you can not get the full discharge with respect to the frequency of manual measurement when it is not enough status information dialysate.
