Description

Technical Field

[0001] The invention belongs to the technical field of medical detection, and in particular relates to a device for detecting the water content of blood during hemodialysis. Background Art

[0002] The main purpose of detecting the water content in the blood is to evaluate fluid balance, including diagnosing dehydration or edema, monitoring the function of organs such as the kidneys and heart, assisting in the diagnosis of metabolic diseases such as diabetes and the accompanying electrolyte imbalance, and playing a role in optimizing clinical treatment plans such as guiding infusion therapy and evaluating drug efficacy.

[0003] Traditional centrifugal separation methods require blood samples to be centrifuged and then the water content is determined by chemical analysis or physical measurement. This process not only involves multiple steps, but the processing time for each sample is usually measured in hours, which is obviously impractical for emergency departments or large-scale screening scenarios. In addition, these devices are often bulky and not suitable for portable use, which limits their application scenarios. Secondly, centrifuges and their supporting reagents are expensive and maintenance costs are not low, which makes it difficult for many medical institutions to bear the economic pressure brought by long-term operation. High costs have become one of the main obstacles to the popularization of advanced detection technologies. In addition, since blood samples may carry pathogens, it is crucial to ensure the safety and sterility of the detection instruments. However, the design of existing equipment is not convenient for thorough cleaning and disinfection, which increases the risk of cross-infection, especially when samples from different patients are frequently replaced. Strict disinfection procedures not only prolong the turnaround time, but also increase the difficulty and potential risks of operation. Summary of the invention

The disinfection belt 310 needs to be immersed in disinfectant before use. The disinfectant can be medical alcohol, so as to facilitate the subsequent rapid covering and disinfection of medical waste generated by blood testing on the upper surface of the oil belt 4 and the water belt 5. One end of the disinfection belt 310 is fixedly connected to the second movable shaft 306, and a first driving member 311 is fixedly installed in the middle of the front of the front second mounting plate 301.

A pipe carrying mechanism 6 is provided between the left feeding mechanism 2 and the rear recovery mechanism 3.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the left feeding mechanism 2 includes two first mounting plates 201, and the two first mounting plates 201 are symmetrically fixedly connected to the left side of the mounting shell 1. The top of the two first mounting plates 201 is fixedly installed with a first support block 202, and the upper surface of the first support block 202 is symmetrically fixedly installed with a first guide block 203. The water hose 5 is slidably sleeved in the middle of the two first guide blocks 203, so as to avoid the bottom surface of the water hose 5 from contacting the upper surface of the first support block 202, and to avoid the moisture attached to the water hose 5 from sticking to the upper surface of the first top block 102, resulting in a decrease in the subsequent watermark detection accuracy of the water hose 5. The left sides of the two first mounting plates 201 are fixedly installed with a first side plate 204, and the middle parts of the two first side plates 204 are movably sleeved with a first movable shaft 205, and the curved surface of the first movable shaft 205 is sleeved with the water hose 5, and the upper parts of the two first side plates 204 are movably sleeved with a first guide shaft 206.

[0024] like Figure 1 and Figure 3 As shown, the tube loading mechanism 6 includes a seat block 601, which is fixedly mounted on the upper part of the left first mounting plate 201 and the right front first mounting plate 201, and a mounting column 602 is fixedly mounted on the upper surface of the seat block 601, and a connecting block 603 is fixedly mounted on the middle part of the right side of the mounting column 602, and a movable sleeve 604 is fixedly mounted on the right side of the connecting block 603, and a carrying ring 605 is slidably sleeved on the middle part of the movable sleeve 604, and a plurality of mounting grooves are equidistantly provided on the upper surface of the carrying ring 605. A plurality of first magnetic rings 606 are fixedly installed at equal intervals on the circumference of the upper surface, a test tube 607 is slidably sleeved in the middle of the plurality of mounting grooves, a second magnetic ring 608 is fixedly installed on the top of the test tube 607, and the magnetic properties of the first magnetic ring 606 and the second magnetic ring 608 in adjacent directions are the same, so that the second magnetic ring 608 pushes the test tube 607 to float above the first magnetic ring 606, so as to prevent the bottom end of the test tube 607 from colliding with the first guide block 203 and the second guide block 305 below it when the carrier ring 605 drives the test tube 607 to rotate. The upper surface of the seat block 601 is fixedly mounted with a second driving member 609, the output end of the second driving member 609 is fixedly mounted with a friction wheel 610, the second driving member 609 is in friction contact with the bottom of the outer curved surface of the object-carrying ring 605, the top of the mounting column 602 is fixedly mounted with a top rod 611, the right side of the bottom surface of the top rod 611 is fixedly mounted with a telescopic rod 612, the middle part of the telescopic rod 612 is fixedly sleeved with an electromagnetic ring 613, the electromagnetic ring 613 has the same magnetic properties as the second magnetic ring 608 in the adjacent direction, and the electromagnetic ring 613 is connected to the second magnetic ring 608. When energized, the magnetism generated by the electromagnetic coil 613 is greater than the magnetism of the first magnetic ring 606, so that when the electromagnetic coil 613 is energized, the magnetic force generated between the electromagnetic coil 613 and the second magnetic ring 608 overcomes the magnetic force generated between the second magnetic ring 608 and the first magnetic ring 606 to push the test tube 607 downward, so that the bottom end of the test tube 607 contacts the upper surface of the oil belt 4, which is convenient for subsequent detection. The telescopic end of the telescopic rod 612 is fixedly installed with a piston 614, and the piston 614 is slidably sleeved with the inner curved surface of the test tube 607 directly below it.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the left side of the horizontal part of the water belt 5 is slidably sleeved in the middle of the two first guide blocks 203 on the left side, the right side of the horizontal part of the water belt 5 is slidably sleeved in the middle of the two second guide blocks 305 on the right side, the rear side of the horizontal part of the oil belt 4 is slidably sleeved in the middle of the two second guide blocks 305 on the front side, and the front side of the horizontal part of the oil belt 4 is slidably sleeved in the middle of the two first guide blocks 203 on the rear side. The oil belt 4 is made of oil-absorbing but non-water-absorbing material, and the oil belt 4 is made of polypropylene fiber cloth, thereby increasing the oil absorption capacity of the oil belt 4 and reducing the water absorption capacity of the oil belt 4. The water belt 5 is made of water-absorbing material and is made of uncoated paper, thereby increasing the watermark diffusion area on the surface of the water belt 5 and improving the detection accuracy.

[0026] Working principle:

[0027] When the present invention is used, the second magnetic ring 608 is first started, and the output shaft of the second magnetic ring 608 drives the second driving member 609 to rotate clockwise intermittently, and the second driving member 609 drives the carrier ring 605 to rotate clockwise intermittently, and then in the gap when the carrier ring 605 stops rotating, the test tube 607 containing quantitative blood is inserted into the installation groove provided in the carrier ring 605 through the middle of the first magnetic ring 606. At this time, since the magnetic properties of the adjacent sides of the first magnetic ring 606 and the second magnetic ring 608 are the same, the second magnetic ring 608 pushes the test tube 607 to float above the first magnetic ring 606, thereby preventing the bottom end of the test tube 607 from intersecting the first guide block 203 and the second guide block 203 at its bottom when the carrier ring 605 drives the test tube 607 to rotate. When the object ring 605 drives the test tube 607 to move to the right below the electromagnetic ring 613, the electromagnetic ring 613 is energized. Since the magnetism of the electromagnetic ring 613 and the adjacent side of the second magnetic ring 608 is the same, and the magnetism of the electromagnetic ring 613 is greater than that of the first magnetic ring 606, the electromagnetic ring 613 drives the second magnetic ring 608 to drive the test tube 607 to move downward, so that the bottom end of the test tube 607 contacts the middle of the upper surface of the oil belt 4 below it, and then the telescopic end of the telescopic rod 612 is started to drive the piston 614 to move downward, and the piston 614 is inserted into the inner cavity of the test tube 607. The piston 614 squeezes the blood in the inner cavity of the test tube 607 to the middle of the upper surface of the oil belt 4, thereby realizing the subsequent rapid and continuous detection of the blood;

[0028] When the piston 614 squeezes the blood in the inner cavity of the test tube 607 to the middle of the upper surface of the oil belt 4, the oil belt 4 absorbs the grease in the blood. At the same time, the oil belt 4 isolates the solid particles such as red blood cells in the blood from the water belt 5. The water in the blood flows through the oil belt 4 to the upper surface of the water belt 5 and is absorbed by the water belt 5. It diffuses on the surface of the water belt 5 to form a circular watermark. The grease in the blood forms a circular oil mark on the surface of the oil belt 4. Then the two first driving members 311 are started. The output end of the right first driving member 311 drives the water belt 5 to rotate to the right through the second movable shaft 306 fixedly connected thereto. The output end of the rear first driving member 311 drives the oil belt 4 to rotate backward through the second movable shaft 306 fixedly connected thereto. When the center of the oil mark on the oil belt 4 moves The oil belt 4 moves to the center of the multiple light rings 304 on the rear side. At this time, the two first driving members 311 are powered off at the same time, and the center of the circular watermark on the water belt 5 moves synchronously to the center of the multiple light rings 304 on the right side. Then, the multiple light rings 304 are powered on. At this time, the multiple light rings 304 generate light rings of different colors. At this time, the oil content in the blood can be obtained by covering the area of ​​the light rings of the multiple light rings 304 on the rear side with the oil print on the surface of the oil belt 4. Similarly, the water content in the blood can be obtained by covering the area of ​​the light rings of the multiple light rings 304 on the right side with the watermark on the surface of the water belt 5. Thus, the water content and oil content in the blood can be quickly detected in a low-cost manner, overcoming the problems of high detection cost, slow speed, and unsuitability for large-scale and rapid detection of existing centrifugal blood water content detection equipment;

[0029] In addition, after the multiple light rings 304 on the rear side of the present invention detect the oil print on the upper surface of the oil belt 4 and the multiple light rings 304 on the right side detect the circular watermark on the upper surface of the water belt 5, the first driving member 311 is started again, and the output end of the first driving member 311 on the rear side drives the second movable shaft 306 fixedly connected to it to rotate, and the second movable shaft 306 on the rear side drives the detected oil belt 4 to roll into a circle, and the second movable shaft 306 on the rear side drives the oil belt 4 and the disinfection belt 310 to roll into a circle, and the disinfection belt 310 wraps the oil belt 4 and impurities such as blood cells on the surface of the oil belt 4, so that the alcohol adsorbed by the disinfection belt 310 can disinfect the detected blood waste, thereby realizing the rapid and safe recovery of medical waste generated by the blood after the detection.
