Description

Technical Field

[0001] The present invention belongs to the technical field of diabetic nephropathy patient detection, and specifically relates to a rapid detection device for diabetic nephropathy patients. Background Art

[0002] Diabetic nephropathy is a common microvascular complication of diabetes, and patients often experience peripheral circulatory disorders, fragile skin, and hand edema. Currently, blood glucose testing, as a key step in diabetes management, mainly relies on traditional blood glucose meters, but these meters have the following limitations in practical applications: The traditional method involves manually squeezing the fingers to obtain blood samples. Excessive force can easily damage tissues, while insufficient force can result in insufficient blood sample volume. This can easily lead to deviations in test results, especially for patients with poor peripheral circulation. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a rapid detection device for patients with diabetic nephropathy. By setting an adaptive adjustment mechanism, an extrusion force adjustment structure and an automatic blood collection structure, the extrusion force of the auxiliary blood collection structure for the person to be tested is adaptively adjusted according to the different thicknesses of the hands of the person to be tested, ensuring that the device can take out a sufficient amount of blood for testing, and can avoid the presence of tissue fluid groups in the blood that affect the test results, thereby improving the detection accuracy of the device, and effectively solving the problem that the detection devices currently used on the market obtain blood samples by manually squeezing the fingers, which may cause damage to tissues due to excessive force, and insufficient force may lead to insufficient blood sample volume, and the test results may be prone to deviations.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a rapid detection device for patients with diabetic nephropathy, including a blood glucose detection component, an adaptive adjustment mechanism, an extrusion pressure adjustment structure and an automatic blood collection mechanism. The adaptive adjustment mechanism is arranged on the blood glucose detection component, the extrusion pressure adjustment structure is arranged inside the blood glucose detection component, and the extrusion pressure adjustment structure is connected to the adaptive adjustment mechanism. The extrusion pressure adjustment structure includes an adjustment component and a reciprocating displacement component, and the automatic blood collection mechanism is arranged on the blood glucose detection component.

[0005] Furthermore, the adaptive adjustment mechanism includes a lifting track, and the lifting plate 1 and the lifting plate 2 are both slidably connected between the lifting tracks.

[0006] Furthermore, a lifting rack is fixedly connected to the lifting plate 2, and the lifting rack is slidably connected to the lifting slot.

[0007] Furthermore, the adaptive adjustment mechanism also includes a driving pulley, the outer surface of which is provided with connecting teeth, and the driving pulley is engaged with the lifting rack through the connecting teeth.

[0008] Furthermore, the adjustment assembly includes a driven bevel gear, which is meshed with the driving bevel gear. A threaded rod is fixedly connected to the driven bevel gear, and an adjustment slide is threadedly connected to the threaded rod.

[0009] Furthermore, the reciprocating displacement assembly includes a driving motor and a sliding ring, the output end of the driving motor is connected to a reciprocating screw, the sliding ring is fixedly connected to a control rod, and the reciprocating screw is threadedly connected to the control rod.

[0010] Furthermore, the automatic blood collection mechanism includes an electric telescopic rod, a slider is fixedly connected to the output end of the electric telescopic rod, and an end of the slider away from the fixed bracket is fixedly connected to the placement plate.

[0011] Furthermore, a limiting sliding groove is provided on the placement plate, a clamping plate is slidably connected inside the limiting sliding groove, and a lifting spring is provided between the clamping plate and the placement plate.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: To address the problem that currently available testing devices on the market obtain blood samples by manually squeezing the finger, excessive force can easily damage tissue, while insufficient force can lead to insufficient blood sample volume, which can easily lead to deviations in test results, the present invention provides an adaptive adjustment mechanism, a squeezing force adjustment structure, and an automatic blood collection structure. The squeezing force of the blood collection mechanism is adaptively adjusted according to the thickness of the subject's hand, ensuring that the device can extract a sufficient amount of blood for testing and preventing the presence of tissue fluid in the blood that could affect the test results, thereby improving the device's detection accuracy. The adaptive adjustment mechanism can drive the driven bevel gear to rotate through the cooperation of the lifting track, lifting plate 1, lifting plate 2 and the adjustment spring. The extrusion force adjustment structure can move the position of the adjustment slide through the drive of the driven bevel gear, so that the distance between the extrusion plate and the adjustment slide can be adjusted, and then the extrusion force applied by the extrusion plate to the position of the finger of the person to be tested can be adjusted, further optimizing the distribution of the extrusion force and improving the blood collection effect. The automatic blood collection mechanism automates the blood collection process. The electric telescopic rod precisely controls the extension and retraction distance of the lancet, eliminating the potential errors and infection risks associated with manual operation. An infrared sensor senses the finger's position and electrically connects to the electric telescopic rod, enabling precise triggering of automatic blood collection and improving detection efficiency.

[0025] The blood glucose detection assembly 1 includes a blood glucose meter 101, to which a protective shell 102 is fixedly connected, a fixed shaft 103 is rotatably connected to the blood glucose meter 101, a rotating plate 104 is fixedly connected to the fixed shaft 103, a test paper inlet and outlet 105 is opened on the blood glucose meter 101, a limit block 106 is fixedly connected inside the test paper inlet and outlet 105, and an infrared sensor 107 is fixedly connected inside the blood glucose meter 101.

[0026] The width of the limiting plate 314 at both ends is greater than the width at the middle.

[0027] The lifting rack 206 passes through and is slidably connected to the protective shell 102 . The infrared sensor 107 is electrically connected to the electric telescopic rod 402 . The position of the infrared sensor 107 corresponds to the center position of the sliding ring 305 .

[0028] During specific use, first manually pull open the rotating plate 104 set on the blood glucose meter 101, then push the needle needed for blood collection to push the clamping plate 407, so that the clamping plate 407 stretches the lifting spring 408 and moves upward along the limiting slide 406. After the needle is placed between the clamping plate 407 and the lifting spring 408, the clamping plate 407 will limit the needle under the action of the lifting spring 408, and then close the rotating plate 104, and put the test paper for detection into the interior of the blood glucose meter 101 through the test paper inlet and outlet 105.

[0029] The person to be tested puts his hand into the interior of the blood glucose meter 101 from between the lifting plate 1 202 and the lifting plate 2 203. The distance between the lifting plate 2 203 and the lifting plate 1 202 is adaptively adjusted according to the thickness of the hand of the person to be tested. When the thickness of the hand is small, the adjustment range of the distance between the lifting plate 1 202 and the lifting plate 2 203 is small. The lifting plate 203 drives the lifting rack 206 to move upward and squeezes the adjustment spring 204 connected between the lifting plate 203 and the lifting rail 201. The displacement distance of the lifting rack 206 is small. The lifting rack 206 moves upward and drives the driving pulley 207 to rotate through the connecting tooth 208. The driving pulley 207 drives the driven pulley 210 to rotate synchronously in the same direction through the transmission belt 211. The driven pulley 210 drives the rotating shaft 212 to rotate, and the rotating shaft 212 drives the driving bevel gear 213 to rotate.

[0030] After the cam 312 is in the process of being moved, the cam 312 of the locking cam 314 is unlocked, and the locking cam 312 is unlocked, and the cam 312 of the locking cam 314 is unlocked. 5. After the drive motor 315 is started, it drives the reciprocating screw 316 to rotate. The rotation of the reciprocating screw 316 drives the sliding ring 305 to move back and forth through the control rod 306. As the sliding ring 305 moves, the control rod 306 provided on the sliding ring 305 slides back and forth along the sliding groove 304. As the sliding ring 305 moves, the top of the squeezing plate 308 moves along the limit plate 314. When the squeezing plate 308 moves to a position with a smaller width on the limit plate 314, the squeezing plate 308 moves to the finger of the person to be tested. As the sliding ring 305 moves, the finger is squeezed, causing the person to be tested's blood to drip onto the test strip inside the blood glucose meter 101. Finally, the staff member withdraws the test strip from the test strip inlet and outlet 105 and inserts it into the blood glucose meter 101 for testing. The electrons generated by the enzyme reaction on the test strip are captured by the electrodes, forming a current signal. The current is proportional to the glucose concentration. The instrument converts the current into a blood glucose value using a calibration curve, and the blood glucose value is displayed on the display screen of the blood glucose meter 101.

[0031] When the thickness of the hand of the person to be tested is large, the displacement distance of the lifting plate 203 is large, the displacement distance of the lifting rack 206 increases, the spacing between the adjustment slides 303 decreases, and the extrusion force provided to the extrusion plate 308 by the telescopic spring 312 increases to ensure that the blood can be squeezed out. The above is the overall workflow of the present invention. Just repeat this step next time you use it. The actual operation process is very simple and easy.
