Description
Translated fromChinese技术领域technical field
本发明涉及医疗器械技术领域，尤其涉及一种双滤式血液净化透析系统及其使用方法。The invention relates to the technical field of medical devices, in particular to a double-filter blood purification dialysis system and a method for using the same.
背景技术Background technique
血液净化在日常生活中我们称它为透析。它的涵义是：把患者的血液引出身体外并通过一种净化装置，除去其中某些致病物质，净化血液，达到治疗疾病的目的。血液净化应包括：血液透析、血液滤过、血液灌流、血浆置换、免疫吸附等。Blood purification in daily life we call it dialysis. Its meaning is: the patient's blood is drawn out of the body and passed through a purification device to remove some of the pathogenic substances, purify the blood, and achieve the purpose of curing diseases. Blood purification should include: hemodialysis, hemofiltration, hemoperfusion, plasma exchange, immunoadsorption, etc.
其中血液滤过和血液透析均可靠应用置换液。目前，临床进行连续性血液过滤治疗时使用的置换液有袋装成品液和袋装自配液两种。其中袋装成品液的成分固定，不能满足所有患者的治疗要求；而袋装自配液虽可根据患者病情需要，实时调整液体成分，但自配液一般仅通过简单的搅拌混合，使得药液混合不均匀，进而影响置换药液的药效，导致对血液的净化效果差；同时多种药液倾倒在一起集中混合，影响对药液的混合速率，进而影响对血液净化的效率。Among them, hemofiltration and hemodialysis are reliable application of replacement fluid. At present, there are two types of replacement fluids used in clinical continuous hemofiltration therapy: bagged finished solution and bagged self-dispensing solution. Among them, the composition of the bagged finished liquid is fixed, which cannot meet the treatment requirements of all patients; while the bagged self-dispensing liquid can adjust the liquid composition in real time according to the needs of the patient's condition, but the self-dispensing liquid generally only needs to be simply stirred and mixed to make the liquid medicine. The mixing is uneven, which affects the efficacy of the replacement medicinal solution, resulting in poor blood purification effect; at the same time, multiple medicinal solutions are poured together and mixed together, which affects the mixing rate of the medicinal solution, which in turn affects the efficiency of blood purification.

本发明还公开了一种双滤式血液净化透析系统的使用方法，包括以下步骤：The invention also discloses a method for using the double-filter blood purification dialysis system, comprising the following steps:
S1：装置使用时首先对置换液进行调配，每个药液箱内均分装不同的药液，根据各自用量对药液进行出液，并通过导管流动至输料管中，再通过输料管进入混合箱内，随后控制搅拌机构工作，对混合箱内的药液进行混合；S1: When the device is in use, firstly, the replacement fluid is prepared. Each medicine solution tank is divided into different medicine solutions, and the medicine solutions are discharged according to their respective dosages, and flow into the conveying pipe through the catheter, and then pass the material through the conveying pipe. The tube enters the mixing box, and then controls the stirring mechanism to mix the liquid medicine in the mixing box;
S2：控制驱动电机运行，使驱动电机的输出端通过转轴带动转动杆转动，转动杆转动时使搅拌片对混合箱内的药液进行混合工作，搅拌片在工作时间歇性的对移动杆作用力，使移动杆带动齿条架上移，当搅拌片不与移动杆相抵时，齿条架在第一弹性元件的拉力下下移，使齿条架在输料管外侧上下往复移动。S2: Control the operation of the drive motor, so that the output end of the drive motor drives the rotating rod to rotate through the rotating shaft. When the rotating rod rotates, the stirring blade mixes the liquid medicine in the mixing box, and the stirring blade intermittently acts on the moving rod during operation. When the stirring plate does not touch the moving rod, the rack will move down under the pulling force of the first elastic element, so that the rack will move up and down on the outside of the conveying pipe.
S3：齿条架上移时通过弹性伸缩杆带动连接件上移，连接件带动封堵块离开下料通道区域，直至连接板与活动槽的底壁相抵，封堵块与输料管内壁相抵，封堵块无法继续上移，与此同时，齿条架上的第三齿条与第一转杆上的第三齿轮啮合，使第一转杆转动并使隔板转动，当隔板由竖直状态转动至水平状态后，隔板与输料管内壁的挡板相抵接，隔板无法继续转动，此时封堵块与隔板隔断输料管的进料与出料，随着齿条架的继续上移，弹性伸缩杆被挤压，齿牙移动组件工作，且齿条架上的第一齿条和第二齿条分别与第一齿轮和第二齿轮啮合，使内杆和外管相对转动，进而使第一搅拌叶和第二搅拌叶对封堵块与隔板之间的少量混合药液进行搅拌，使其可以快速均匀混合，当齿条架在第一弹性元件的拉力作用下下移时，隔板和封堵块复位不再对输料管进行隔断，使得初步混合的药液进入混合箱再次进行混合工作，且隔板和封堵块等待再次对输料管中进入的药液进行收集；S3: When the rack frame moves up, the connecting piece is moved up by the elastic telescopic rod, and the connecting piece drives the blocking block to leave the unloading channel area until the connecting plate and the bottom wall of the movable groove are in contact, and the blocking block is in contact with the inner wall of the conveying pipe. , the blocking block cannot continue to move up, at the same time, the third rack on the rack frame meshes with the third gear on the first rotating rod, so that the first rotating rod rotates and the partition plate rotates. After the vertical state is rotated to the horizontal state, the baffle plate is in contact with the baffle plate on the inner wall of the conveying pipe, and the baffle plate cannot continue to rotate. At this time, the blocking block and the baffle plate block the feeding and discharging of the conveying pipe. The rack continues to move upward, the elastic telescopic rod is squeezed, the tooth moving component works, and the first rack and the second rack on the rack rack mesh with the first gear and the second gear respectively, so that the inner rod and the The outer tube rotates relatively, so that the first stirring blade and the second stirring blade stir a small amount of mixed liquid between the blocking block and the partition plate, so that it can be mixed quickly and evenly. When moving down under the action of pulling force, the separator and the blocking block are reset and no longer block the feeding pipe, so that the preliminary mixed liquid enters the mixing box for mixing again, and the separator and blocking block wait for the feeding pipe to be blocked again. Collect the liquid medicine entering in;
S4：在齿牙移动组件工作时，第三齿轮对齿牙件进行抵压，使齿牙件相对齿条架下移，使齿牙件带动滑块下移，滑块通过推杆带动活塞下移，使活塞挤压活动管内抽取自第二导管内的药液，使药液从第三导管排出并进入外管，使得外管在转动过程中喷洒第三药液箱内的药液，使第三药液箱内的药液充分与第一药液箱和第二药液箱内的药液混合；S4: When the tooth moving component is working, the third gear presses the tooth part, so that the tooth part moves down relative to the rack frame, so that the tooth part drives the slider down, and the slider drives the piston down through the push rod move, so that the piston squeezes the liquid medicine extracted from the second conduit in the movable tube, so that the liquid medicine is discharged from the third conduit and enters the outer tube, so that the outer tube sprays the liquid medicine in the third liquid medicine tank during the rotation process, so that the The liquid medicine in the third liquid medicine tank is fully mixed with the liquid medicine in the first liquid medicine tank and the second liquid medicine tank;
S5：经混合箱最终搅拌后的混合药液在输液管的作用下导入净化筒体，净化筒体的进液口与外界供血管路固定连通，同时将出液口与外界回血管路固定连通后，血液经进液口进入到净化筒体内并向前流动与取自混合箱内的调配置换液置换反应，随后穿过滤网，净化后的血液经出液口排出进入外界回血管路。S5: The mixed medicinal solution after being finally stirred by the mixing box is introduced into the purification cylinder under the action of the infusion tube, the liquid inlet of the purification cylinder is fixedly connected with the external blood supply circuit, and the liquid outlet is fixedly connected with the external return blood circuit. Afterwards, the blood enters the purification cylinder through the liquid inlet and flows forward and reacts with the replacement liquid taken from the mixing box, and then passes through the filter screen, and the purified blood is discharged through the liquid outlet into the external return circuit.
与现有技术相比，本发明提供了一种双滤式血液净化透析系统及其使用方法，具备以下有益效果：Compared with the prior art, the present invention provides a double-filter blood purification dialysis system and a method for using the same, which have the following beneficial effects:
1、该双滤式血液净化透析系统及其使用方法，通过搅拌机构驱动定量混合机构工作，使装置可以对间歇性的对少量的混合药液进行初步混合，提高药液的混合速率，避免大量药液集中后再混合，导致药液混合效果差、效率低的问题，进而保证对血液的净化效果和净化效率。1. The dual-filter blood purification dialysis system and its use method are driven by the stirring mechanism to drive the quantitative mixing mechanism to work, so that the device can intermittently mix a small amount of mixed liquid medicine, improve the mixing rate of the liquid medicine, and avoid a large amount of liquid medicine. After the medicinal liquid is concentrated and then mixed, the problems of poor medicinal liquid mixing effect and low efficiency are caused, thereby ensuring the purification effect and purification efficiency of the blood.
2、该双滤式血液净化透析系统及其使用方法，通过控制内杆和外管相对转动，进而使第一搅拌叶和第二搅拌叶对封堵块与隔板之间的药液充分搅拌，提高药液混合的均匀性。2. The dual-filter blood purification dialysis system and its using method control the relative rotation of the inner rod and the outer tube, so that the first stirring blade and the second stirring blade can fully stir the medicinal liquid between the blocking block and the partition plate , improve the uniformity of liquid mixing.
3、该双滤式血液净化透析系统及其使用方法，通过齿牙移动组件工作，使第三药液箱内的药液随着外管的转动而喷洒在封堵块与隔板之间的药液内，使第三药液箱内的药液充分与第一药液箱和第二药液箱内的药液混合，提高药液的混合速率和混合效果。3. The double-filter blood purification dialysis system and its using method work through the teeth moving components, so that the medicinal solution in the third medicinal solution tank is sprayed between the blocking block and the baffle along with the rotation of the outer tube. In the liquid medicine, the liquid medicine in the third liquid medicine tank is fully mixed with the liquid medicine in the first liquid medicine tank and the second liquid medicine tank, so as to improve the mixing rate and mixing effect of the liquid medicine.
4、该双滤式血液净化透析系统及其使用方法，通过第一弹性元件的劲度系数大于第二弹性元件的劲度系数，使得搅拌片与移动杆相抵时，搅拌片会率先挤压第二弹性元件，使搅拌片下移，进而提高搅拌片在混合箱内的搅拌范围，避免出现搅拌死角，进而保证对药液的搅拌混合效果。4. In the double-filter blood purification dialysis system and its use method, the stiffness coefficient of the first elastic element is greater than the stiffness coefficient of the second elastic element, so that when the stirring blade is in contact with the moving rod, the stirring blade will squeeze the first elastic member first. Two elastic elements make the stirring blade move down, thereby increasing the stirring range of the stirring blade in the mixing box, avoiding the occurrence of a stirring dead angle, and ensuring the stirring and mixing effect of the liquid medicine.
