Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, relates to a portable blood potassium detection device. Background Technology

[0002] Therefore, patients with kidney disease need frequent monitoring of their serum potassium levels to prevent hyperkalemia. For patients in the uremic stage (dialysis patients), monitoring is required before and after each dialysis session (because dialysis rapidly removes potassium, it is necessary to assess the effectiveness of dialysis and changes in serum potassium levels between dialysis sessions). For patients with acute kidney injury or high-risk factors (such as those using ACEIs plus potassium-sparing diuretics), weekly or even daily monitoring of serum potassium may be necessary. However, the unique characteristics of kidney disease patients, their limited mobility, high frequency of medical visits, cumbersome hospital procedures, and uneven distribution of medical resources make the cost of potassium testing at the hospital high, causing inconvenience and reducing the frequency of monitoring, indirectly increasing the risk of abnormal serum potassium levels.

[0029] Please refer to the following: Figures 1 to 5This utility model provides a portable blood potassium testing device, comprising a housing 1 with an inner cavity, a mounting bracket 2 disposed within the housing 1, a connecting mechanism 3 disposed on the mounting bracket 2, an electrode detection mechanism 4, and a peristaltic pump 5; the housing 1 is provided with a first container 7 for storing cleaning fluid and a second container 8 for temporarily storing waste fluid, a first pipe 12 connecting the first container 7 and the connecting mechanism 3, a second pipe 13 connecting the peristaltic pump 5 and the second container 8, and a first clearance for the first pipe 12 to penetrate through the mounting bracket 2 at the corresponding position of the connecting mechanism 3. Hole 21, mounting bracket 2 is provided with a second clearance hole 22 through which the second pipe 13 passes through at the corresponding position of the peristaltic pump 5; a first delivery pipe 15 is provided between the connecting mechanism 3 and the electrode detection mechanism 4, and a second delivery pipe 16 is provided between the electrode detection mechanism 4 and the peristaltic pump 5; the peristaltic pump 5 includes a flexible hose 51 for connecting the second delivery pipe 16 and the second pipe 13, a peristaltic roller 52 for squeezing the flexible hose 51, and a drive motor 53 for driving the peristaltic roller 52 to rotate; a sampling tube 11 is provided on the connecting mechanism 3 for connecting with a sampling bottle 6 that temporarily stores the liquid to be tested. When the internal tubing of the portable potassium level testing device needs cleaning or low-concentration calibration, the connecting mechanism 3 connects the first pipe 12 and the first delivery pipe 15. The peristaltic pump 5's drive motor 53 drives the peristaltic roller 52 to rotate, causing the peristaltic roller 52 to squeeze the flexible tubing 51, creating a partial vacuum. This draws the cleaning solution from the first container 7. The cleaning solution flows sequentially through the first pipe 12, the connecting mechanism 3, and the first delivery pipe 15, and is delivered to the electrode detection mechanism 4 for cleaning or testing, measuring the voltage between the two electrodes. The peristaltic pump 5 then draws the cleaning solution out of the electrode detection mechanism 4, and sequentially flows through the second delivery pipe 16, the flexible tubing 51, and the second pipe 13. The sample is then temporarily stored in the second container 8. When the portable potassium testing device tests the liquid being tested, the connecting mechanism 3 connects the sampling tube 11 and the first delivery tube 15. The peristaltic pump 5 is activated to draw the liquid being tested from the sampling bottle 6. The liquid being tested flows sequentially through the sampling tube 11, the connecting mechanism 3, and the first delivery tube 15 and is then transported to the electrode detection mechanism 4 for testing. The voltage between the two electrodes is measured. The peristaltic pump 5 draws the liquid being tested out of the electrode detection mechanism 4 and flows sequentially through the second delivery tube 16, the flexible hose 51, and the second pipe 13. Finally, it is transported to the second container 8 for temporary storage. Based on the read test data, the potassium ion concentration of the liquid being tested is calculated.The portable blood potassium testing device provided by this utility model can quickly obtain test results by collecting a small amount of whole blood from the fingertip of kidney disease patients. It is easy to operate, has simple components, small size, and low manufacturing cost. It is suitable for use in various places such as homes, pharmacies, and community medical institutions.

[0030] Optionally, the mounting bracket 2 is provided with a clamping bracket 24 for holding the sampling tube 11. The sampling tube 11 is securely placed in a preset position on the housing 1 by the clamping bracket 24, which is convenient for the user to use.

[0031] Please refer to the following: Figure 3 , Figure 5 and Figure 7 In this embodiment, the electrode detection mechanism 4 uses the ion-selective electrode method to detect potassium in the test liquid, which is a recognized reference detection method. The electrode detection mechanism 4 analyzes the sample using the ion-selective electrode method, utilizing the selective response of a specific electrode to potassium ions in the test liquid, and measures the electrode potential to determine the potassium ion concentration. Specifically, based on the Nernst equation, when the ion-selective electrode and the reference electrode form a measuring cell, there is a quantitative relationship between the electrode potential and the activity (approximate concentration) of the target ion in the solution. The ion concentration can be calculated by measuring the potential value. Its advantages are that the specific electrode is sensitive to the target ion, less affected by interference from other ions, requires no complex pretreatment, and facilitates rapid detection.

[0032] Optionally, the electrode detection mechanism 4 includes an electrode detection component 41 for detecting the liquid to be tested, a heating component 42 for heating the electrode detection component 41, and a liquid level sensor 43 for monitoring the liquid level of the solution in the second delivery pipe 16. The electrode detection component 41 is heated by the heating component 42, so that the electrode detection component 41 can perform detection operations within a preset ambient temperature, which helps to ensure the accuracy and precision of the detection results. Furthermore, by setting the liquid level sensor 43 on the second delivery pipe 16 for monitoring the liquid level of the solution in the second delivery pipe 16, the real-time liquid level in the second delivery pipe 16 can be monitored, thereby enabling real-time monitoring of the real-time liquid level of the electrode detection component 41, ensuring that the liquid to be tested has been delivered to the electrode detection component 41 for detection.

[0033] Optionally, the heating component 42 includes a heating element 421 for heating the electrode detection component 41, and a temperature sensor 422 for monitoring the temperature of the electrode detection component 41. The heating element 421 heats the electrode detection component 41 to a preset temperature, and the temperature sensor 422 monitors the temperature of the electrode detection component 41 in real time. When the electrode detection component 41 reaches the preset temperature, heating is stopped in time. When the electrode detection component 41 is lower than the preset temperature, the heating element 421 is activated in time to heat it, ensuring that the electrode detection component 41 is kept constant at the preset temperature for detection operations, which helps to ensure the accuracy and precision of the detection results.

[0034] Optionally, the ambient temperature of the electrode detection component 41 during operation is kept constant at 37 degrees Celsius. When the portable blood potassium testing device is started, the heating component 42 needs to be activated first to heat the electrode detection component 41. The temperature of the electrode detection component 41 is monitored by the temperature sensor 422 to keep the electrode detection component 41 at a constant temperature of 37 degrees Celsius, ensuring that the electrode detection component 41 is kept constant at the preset temperature for testing.

[0035] Optionally, the second container 8 is a disposable waste liquid collection bottle containing disinfectant, which can disinfect and render harmless the waste liquid generated during the operation of the portable blood potassium testing device, preventing biological hazards.

[0036] Please refer to the following: Figure 1 , Figure 2 and Figure 5 As a specific embodiment of the portable potassium testing device provided by this utility model, the portable potassium testing device also includes a third container 9 disposed on the housing 1 for storing standard solution. A third pipe 14 is provided between the third container 9 and the connecting mechanism 3, and the third pipe 14 is provided through the first clearance hole 21. When the portable potassium testing device needs to be calibrated or subjected to high-concentration calibration, the connecting mechanism 3 connects the third pipe 14 and the first delivery pipe 15. The peristaltic pump 5 is started to draw the standard solution in the third container 9. The standard solution flows through the third pipe 14, the connecting mechanism 3, and the first delivery pipe 15 in sequence and is delivered to the electrode detection mechanism 4 for detection, measuring the voltage between the two electrodes. The peristaltic pump 5 draws the standard solution out of the electrode detection mechanism 4, flows through the second delivery pipe 16, the flexible hose 51, and the second pipe 13 in sequence, and is finally delivered to the second container 8 for temporary storage. By checking the test results output by the portable potassium testing device, the accuracy and precision of the test results of the portable potassium testing device can be obtained.

[0037] Please refer to the following: Figure 3 , Figure 5 and Figure 6In this embodiment, the connecting mechanism 3 includes a telescopic motor 31 and a valve 32 fixedly connected to the telescopic motor 31. The mounting frame 2 is provided with a fixing frame 23 for fixing the telescopic motor 31. The connecting mechanism 3 is stably installed on the mounting frame 2 by the fixing frame 23. The telescopic motor 31 drives the valve 32 to move up and down relative to the mounting frame 2, so that the valve 32 is connected to the first pipe 12, the third pipe 14 and the sampling pipe 11 respectively, so as to deliver different solutions to the electrode detection mechanism 4.

[0038] Optionally, valve 32 includes valve core 321 fixedly connected to telescopic motor 31 and valve body 323 fixedly connected to fixing frame 23. Valve core 321 is provided with a connecting hole 322, and valve body 323 is provided with a penetrating hole 324 for valve core 321 to penetrate. Valve body 323 is connected to first pipe 12, third pipe 14 and sampling tube 11 respectively. The telescopic motor 31 drives valve core 321 to move up and down relative to valve body 323 in the penetrating hole 324 of valve body 323, so that the connecting hole 322 of valve core 321 can be connected to first pipe 12, third pipe 14 and sampling tube 11 at different height positions. Thus, when valve core 321 is at different height positions, first pipe 12, third pipe 14 and sampling tube 11 can be connected to first delivery pipe 15 respectively, so as to deliver the required solution to electrode detection mechanism 4.

[0039] Optionally, a first position sensor 33 is provided on the fixing frame 23 to monitor the position of the valve core 321, thereby monitoring the height position of the valve core 321 in real time, so as to control the start and stop and extension stroke of the telescopic motor 31, and realize the delivery of the required solution to the electrode detection mechanism 4.

[0040] Please refer to the following: Figure 4 As shown in the figure, in this embodiment, the peristaltic pump 5 of the portable blood potassium testing device drives the peristaltic roller 52 to rotate via the drive motor 53. When the peristaltic roller 52 rolls on the surface of the flexible hose 51, it squeezes the surface of the flexible hose 51 in sequence, so that the squeezed part forms a sealed space, pushing the internal fluid forward. After the peristaltic roller 52 leaves, the flexible hose 51 returns to its original shape due to its own elasticity, forming a partial vacuum, which draws in the subsequent fluid, thereby achieving continuous delivery. Its advantage is that the fluid only comes into contact with the flexible hose 51, avoiding contamination of the fluid by other components of the peristaltic pump 5.

[0041] Optionally, the mounting frame 2 is provided with a support frame 25 for mounting the peristaltic pump 5, so that the peristaltic pump 5 can be stably mounted on the mounting frame 2 at a preset position. The support frame 25 is provided with a second position sensor 54 for monitoring the position of the peristaltic roller 52. The rotation angle position of the peristaltic roller 52 is monitored in real time by the second position sensor 54, so as to monitor the fluid delivery progress of the peristaltic pump 5 in real time.

[0042] Please refer to further information. Figures 1 to 5 In this embodiment, the portable potassium testing device also includes a control module 17 and a touch screen 18 electrically connected to the control module 17. The connecting mechanism 3, the electrode detection mechanism 4, and the peristaltic pump 5 are all electrically connected to the control module 17. The touch screen 18 can be used to control the start / stop and operating mode of the control module 17. The control module 17 can control the operating status of the connecting mechanism 3, the electrode detection mechanism 4, and the peristaltic pump 5, and read the corresponding data, which is then presented to the user for viewing through the touch screen 18. At the same time, a first mounting hole for mounting the touch screen 18 is provided through the housing 1, so that the touch screen 18 can be firmly installed in a preset position on the housing 1, making it convenient for the user to read the test data and operate the portable potassium testing device.

[0043] Optionally, the portable potassium testing device also includes a power interface 19 and a start / stop switch electrically connected to the control module 17. A second mounting hole for installing the power interface 19 and the start / stop switch is provided through the housing 1. By providing a second mounting hole on the housing 1, the power interface 19 and the start / stop switch can be installed in a preset position. The power interface 19 is used to connect to an external power source to provide the necessary power for the operation of the portable potassium testing device. At the same time, the user controls the start and stop of the portable potassium testing device through the start / stop switch. The operation is simple and convenient, which helps to improve the user experience.

[0044] Optionally, the portable blood potassium testing device is also equipped with a disposable capillary blood collection kit, including disposable skin disinfectant, disposable spring lancet, disposable micropipettes, disposable sampling tubes, and a disposable waste box (containing disinfectant solution) to prevent cross-infection.
