Description

Technical Field

[0001] The present invention relates to the technical field of detection sampling, and specifically relates to a diabetes detection device. Background Art

[0002] Diabetes is a metabolic disease caused by insufficient insulin secretion or inadequate insulin action. Long-term hyperglycemia may lead to complications such as diabetic nephropathy. Early diagnosis of diabetic nephropathy usually relies on serum detection. The test strip method is widely used due to its convenience and low cost. Although this method is suitable for primary screening and early detection of kidney problems, it still faces some limitations.

[0003] Currently, the sampling methods for early detection of diabetic nephropathy on the market usually require medical staff to insert the test strip into the serum for detection, and the test strip and serum are exposed to the external environment during the operation. This operation method is prone to interference by external factors, which in turn affects the accuracy of the detection results, and further affects the early prevention and treatment effects of diabetic nephropathy. Summary of the Invention

The annular magnet is magnetically repelled by the electromagnetic ring. A first spring is fixedly installed in the airbag.

The electric contacts are connected to a relay. The relay is electrically connected to the first solenoid valve and the second solenoid valve respectively. The electric contacts are electrically connected to the electromagnetic ring.

[0012] Preferably, a connecting pipe is fixedly installed at the upper end of the second solenoid valve. A telescopic pipe is fixedly installed on the inner wall of the connecting pipe. An L-shaped pipe is hermetically and slidably installed on the outer wall of the telescopic pipe. One end of the L-shaped pipe communicates with the immersion groove. A transparent plate is fixedly installed on the inner wall of the immersion groove.

[0013] Preferably, a liquid outlet groove is opened in the compression tank at a position corresponding to the immersion groove. A plug is hermetically and slidably installed in the liquid outlet groove.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0018] First, through the mutual sliding between the upper tank body and the lower tank body, air pressure is generated in the compression space. The air pressure drives the airbag and the liquid storage bag to descend in the upper tank body. During the descending process, the needle pierces into the liquid storage tank. As the airbag and the liquid storage bag continuously descend and are compressed and deformed due to resistance, then the electric contact and the power-on hole are powered on to enable the electromagnetic ring and the ring magnet to generate magnetic repulsion force, so as to drive the airbag and the liquid storage bag to rise, further compressing the liquid storage bag, causing the air pressure in the liquid storage bag to change, sucking the serum in the liquid storage tank into the liquid storage bag for temporary storage. Through the magnetic repulsion force generated by the electromagnetic ring and the ring magnet, the airbag and the liquid storage bag are continuously driven to rise, and the airbag and the liquid storage bag are compressed again, so that the serum temporarily stored in the liquid storage bag enters the immersion tank through the connecting pipe, the telescopic pipe and the L-shaped pipe to be mixed with the test strip for detection. The whole process only needs to press the upper tank body, which simplifies the detection steps, reduces the difficulty and improves the detection efficiency, avoids the contact of the serum and the test strip with the outside air during the detection process, reduces errors, and improves the credibility of the detection results.

[0019] Second, after the sampling is completed, by repeatedly pressing the upper tank body on the lower tank body, the air pressure in the compression space drives the arc-shaped magnet to approach the armature, allowing a part of the cleaning water to enter the immersion tank for cleaning, and another part of the cleaning water will enter the needle, the liquid storage bag, the connecting pipe, the telescopic pipe and the L-shaped pipe to wash their inner walls, solving the problem of inconvenient cleaning of their inner walls and facilitating subsequent reuse.

[0035] Among them, during the process of the airbag 301 sliding and sleeving with the upper tank body 101 and the lower tank body 102, the negative pressure generated squeezes the airbag 301 to descend, driving the needle 308 to pierce into the liquid storage tank 5. During the process of driving the liquid storage bag 302 to deform, the serum in the liquid storage tank 5 is extracted through the internal air pressure change.

[0036] Refer to Figures 1 to 4, further comprising an intake assembly 2, the intake assembly 2 including a chute opened at the lower end of the upper tank body 101, the chute being hermetically and slidably connected to the inner and outer walls of the lower tank body 102, a partition disc 212 being hermetically and slidably installed on the inner wall of the lower tank body 102, an electromagnetic ring 206 being fixedly installed on the upper end face of the partition disc 212, a sleeve 204 being fixedly installed at the inner bottom end of the lower tank body 102, the sleeve 204 being in clearance fit with the liquid storage tank 5, a diaphragm 6 being embedded in the upper end face of the liquid storage tank 5, a corrugated compression tube 205 being fixedly installed on the lower end face of the partition disc 212, a round hole being opened at the inner bottom end of the corrugated compression tube 205 and corresponding to the position of the diaphragm 6, the liquid storage tank 5 being hermetically plugged with the round hole, a rubber partition 208 being embedded in the partition disc 212, a through hole 210 being opened at the middle position of the inner wall of the rubber partition 208, the function of the through hole 210 being for the needle 308 to pass through the rubber partition 208, the rubber partition 208 being hermetically and slidably connected to the outer wall of the needle 308 due to its shrinkability to reduce the entry of external air into the liquid storage tank 5 through the gap between the rubber partition 208 and the needle 308, the inner diameter of the through hole 210 being smaller than the outer diameter of the needle 308, a plurality of air outlet holes 209 being circumferentially and arrayed on the inner wall of the rubber partition 208, power-on holes 211 being symmetrically opened on the upper end face of the rubber partition 208, a conductive collar being fixedly installed on the inner wall of the power-on holes 211, a conductive block being connected to an external power source, and at least one air outlet 207 being opened on the upper end face of the electromagnetic ring 206.

The bistable relay can switch its state through an external trigger signal (such as the contact and disconnection between the electric contact 307 and the conductive block). The relay has two outputs, which can be respectively connected to the control circuits of the second solenoid valve 304 and the first solenoid valve 303. By electrically connecting the relay with the first solenoid valve 303 and the second solenoid valve 304 (the relay itself is connected to an external power supply), the second solenoid valve 304 is controlled to be normally closed, and the first solenoid valve 303 is controlled to be normally open. After the electric contact 307 contacts the power-on hole 211, the relay will change the normally open and normally closed states of the first solenoid valve 303 and the second solenoid valve 304, so that the first solenoid valve 303 and the second solenoid valve 304 switch between the normally open and normally closed states. The relay is respectively electrically connected to the first solenoid valve 303 and the second solenoid valve 304, and the electric contact 307 is electrically connected to the electromagnetic ring 206.

Water inlet holes are formed in the outer wall of the rotating barrel 411. A fan blade 413 is fixedly installed in the rotating barrel 411. A delivery pipe 414 is communicated with the upper end surface of the rotating barrel 411. The upper end of the delivery pipe 414 is communicated with a liquid injection pipe 415.

Meanwhile, the external water source can be delivered into the fixed box 402 through the water inlet 412.

[0040] The working principle of the present invention is as follows:

[0041] 1. Serum extraction: Slide the liquid storage tank 5 containing serum into the sleeve 204 (the liquid storage tank 5 is an existing vacuum blood collection bottle with a diaphragm 6. These bottles have a special design to prevent contamination and ensure the accuracy of blood samples). The liquid storage tank 5 will airtight seal the round hole. Align the upper tank body 101 with the upper end of the lower tank body 102 and press the upper tank body 101. The upper tank body 101 will squeeze the separating disc 212 to slide in the lower tank body 102. The squeezed separating disc 212 will squeeze the corrugated compression tube 205, causing the air in the corrugated compression tube 205 to pass through the air outlet hole 209, the air outlet 207, and the air inlet groove 103 into the compression space in sequence, increasing the air pressure in the compression space. This will push the airbag 301 to descend in the upper tank body 101 (the sum of the air pressure thrust and gravity is greater than the friction between the airbag 301 and the inner wall of the upper tank body 101, but the airbag 301 will only slide and descend along the inner wall of the upper tank body 101 without deforming). During the descent of the airbag 301, the first solenoid valve 303 is in the open state, and the second solenoid valve 304 is in the closed state (when an external voltage passes through the coil in the solenoid valve, an electromagnetic field will be generated to drive the movement of the valve core). At the same time, when the airbag 301 descends, it will drive the needle 308 to descend together. As the corrugated compression tube 205 is continuously compressed, the needle 308 will pierce into the through hole 210 (the inner diameter of the through hole 210 is smaller than the outer diameter of the needle 308). The through hole 210 will be in airtight sliding connection with the outer wall of the needle 308. After the needle 308 passes through the through hole 210, it will pass through the round hole and pierce the diaphragm 6 into the liquid storage tank 5. When the corrugated compression tube 205 is compressed to the limit, the lower end face of the upper tank body 101 will contact the electromagnetic ring 206, and the airbag 301 will be driven to descend, driving the ring magnet 306 to contact the electromagnetic ring 206 to generate resistance. The airbag 301 will be compressed and deformed by the air pressure in the compression space due to the resistance generated by the contact between the ring magnet 306 and the electromagnetic ring 206. The internal liquid storage bladder 302 will change from an elliptical shape to a slightly flattened shape due to the deformation of the airbag 301 (there is a first spring 305 in the airbag 301 to form an elastic force). The electrical contact 307 will slide into the power-on hole 211 to contact the conductive block and be powered on. The electrical contact 307 will also supply voltage to the electromagnetic ring 206, causing the electromagnetic ring 206 to generate magnetism. When the electromagnetic ring 206 generates magnetism, a magnetic repulsive force will be generated with the ring magnet 306. The magnetic repulsive force will drive the ring magnet 306 to slowly displace upward in the upper tank body 101. The ascending ring magnet 306 will drive the airbag 301 and the liquid storage bladder 302 to move upward together. The compressed airbag 301 and liquid storage bladder 302 will change from a flattened shape to the original elliptical state (a negative pressure is generated during the deformation process), and then suck the serum in the liquid storage tank 5 into the liquid storage bladder 302 through the needle 308. As the ascending ring magnet 306 continuously drives the airbag 301 and the liquid storage bladder 302 to slide upward along the inner wall of the upper tank body 101, the electrical contact 307 will slide out of the power-on hole 211 to disconnect the power supply.The relay then disconnects the voltage supplied to the first solenoid valve 303, causing the valve core of the first solenoid valve 303 to close, and supplies voltage to the second solenoid valve 304, causing the valve core of the second solenoid valve 304 to open;

[0042] As the continuously rising driving airbag 301 and liquid storage bag 302 rise to the top inside the upper tank body 101, the air pressure ring magnet 306 in the compression space will further compress the airbag 301 and liquid storage bag 302 (the magnetic repulsion force generated by the electromagnetic ring 206 and the ring magnet 306 in cooperation with the air pressure in the compression space is greater than the elastic force of the first spring 305), causing the liquid storage bag 302 to deform from an elliptical shape to a completely flat shape. The compressed liquid storage bag 302 will cause the serum extracted inside to be transported through the second solenoid valve 304 with the valve core open to the connecting pipe 309, telescopic pipe 310, and L-shaped pipe 311, and finally discharged into the immersion tank 312 to be mixed with the test strip (when the blood or serum contacts the test strip, the test strip will show the result within a few seconds). After the specified test time according to the existing medical serum test strip, remove the transparent plate 315 and take out the test strip to observe the result;

[0043] Generally speaking, through the mutual sliding between the upper tank body 101 and the lower tank body 102, air pressure is generated in the compression space. The air pressure drives the airbag 301 and the liquid storage bag 302 to descend inside the upper tank body 101. During the descent, the needle 308 pierces into the liquid storage tank 5. As the airbag 301 and the liquid storage bag 302 continue to descend and are compressed and deformed due to resistance, then the electrocontact 307 and the power-on hole 211 are powered on to make the electromagnetic ring 206 and the ring magnet 306 generate magnetic repulsion force to drive the airbag 301 and the liquid storage bag 302 to rise, further compressing the liquid storage bag 302, causing the air pressure inside the liquid storage bag 302 to change and sucking the serum in the liquid storage tank 5 into the liquid storage bag 302 for temporary storage. By the magnetic repulsion force generated by the electromagnetic ring 206 and the ring magnet 306, the airbag 301 and the liquid storage bag 302 are continuously driven to rise, and the airbag 301 and the liquid storage bag 302 are compressed again to make the serum temporarily stored in the liquid storage bag 302 enter the immersion tank 312 through the connecting pipe 309, telescopic pipe 310, and L-shaped pipe 311 to be mixed with the test strip for detection. The whole process only requires pressing the upper tank body 101, which simplifies the detection steps, reduces the difficulty and improves the detection efficiency, avoids the contact of serum and test strip with the outside air during the detection process, reduces errors, and improves the credibility of the detection result;

[0044] 2. Cleaning: After the sampling and detection are completed, take out the liquid storage tank 5, place the lower tank body 102 on a flat tabletop or seal the round hole of the lower tank body 102 with tape. Press the upper tank body 101 again to slide on the inner and outer walls of the lower tank body 102, so as to increase the air pressure in the compression space. Open the third solenoid valve 408 through the controller. The air in the compression space will enter between the slide plate 404 and the external box 403 through the third solenoid valve 408, increasing the air pressure in the external box 403, pushing the slide plate 404 to drive the arc magnet 406 to approach the armature 410, and making the armature 410 rotate (when an external power supply provides voltage to the armature 410, the armature 410 itself will generate a magnetic field. If an external magnet (arc magnet 406) approaches the armature 410, this magnetic field interacts with the voltage in the armature 410. According to Faraday's law of electromagnetic induction, the change in the magnetic field will induce an electromotive force in the armature 410, and this changing magnetic field can cause the armature 410 to rotate). The rotating armature 410 will drive the rotating barrel 411 and the fan blade 413 to rotate, allowing the cleaning water inside the fixed box 402 to enter the rotating barrel 411 through the water inlet hole. As the rotating barrel 411 and the fan blade 413 rotate, the cleaning water generates centrifugal force in the rotating barrel 411 and enters the delivery pipe 414 and the liquid injection pipe 415, and then enters the L-shaped pipe 311 through the one-way valve 416. Part of the cleaning water will enter the immersion tank 312 through the L-shaped pipe 311, and the other part of the cleaning water will enter the liquid storage bag 302 through the inner walls of the telescopic pipe 310 and the connecting pipe 309. Since the air pressure in the compression space flows into the three-way pipe 407 through the third solenoid valve 408, the air pressure in the compression space cannot drive the airbag 301 to descend in the upper tank body 101. After descending for a certain time, the controller closes the third solenoid valve 408, and then repeats pressing the upper tank body 101 to slide on the inner and outer walls of the lower tank body 102 to increase the air pressure in the compression space, driving the airbag 301 to descend, making the electrical contact 307 contact the power-on hole 211 to be powered on. The relay will open the second solenoid valve 304 and close the first solenoid valve 303, allowing the cleaning water in the telescopic pipe 310 and the connecting pipe 309 to enter the liquid storage bag 302 to flush the inside thereof. Release the upper tank body 101 to gradually reduce the air pressure in the compression space as the upper tank body 101 rises. Finally, separate the upper tank body 101 from the lower tank body 102. The powered-on electrical contact 307 and the power-on hole 211 will close the second solenoid valve 304 and open the first solenoid valve 303 through the relay. The cleaning water flushing in the liquid storage bag 302 will flow into the needle 308 due to the opening of the first solenoid valve 303, thus completing the flushing of the inner walls of the needle 308, the liquid storage bag 302, the connecting pipe 309, the telescopic pipe 310 and the L-shaped pipe 311. At the same time, the cleaning water entering the immersion tank 312 will also flush the inside of the immersion tank 312. Pull out the plug 314 to let the cleaning water in the immersion tank 312 flow outwards, facilitating repeated use next time;

[0045] It should be noted that during the process of repeatedly pressing the upper tank body 101 to slide on the inner and outer walls of the lower tank body 102, when the air pressure in the compression space increases to drive the airbag 301 to descend, negative pressure will also be generated inside the airbag 301 and the liquid storage bag 302. When the electrical contact 307 contacts the power-on hole 211 to turn on the power, the valve core of the second solenoid valve 304 is opened and the valve core of the first solenoid valve 303 is closed, the negative pressure generated in the liquid storage bag 302 will suck the cleaning water in the telescopic tube 310 and the connecting tube 309 into the liquid storage bag 302, which can enhance the flushing effect. The flushing method for the inner walls of the cleaning needle 308, the liquid storage bag 302, the connecting tube 309, the telescopic tube 310 and the L-shaped tube 311 can be repeated several times to achieve a better cleaning effect, and the outer wall of the needle 308 is cleaned by soaking in the cleaning water.
