Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, specifically a rapid detection device for malaria parasite infection. Background Technology

[0002] Plasmodium is a single-celled protozoan parasite belonging to the family Plasmodiumceae in the phylum Apicocypriniformes. It is the pathogen that causes malaria in humans. These tiny parasites are mainly transmitted to humans through the bite of infected female Anopheles mosquitoes. Within the human body, they undergo a complex life cycle, including an asexual reproduction stage within liver cells and a schizogony stage within red blood cells. Currently, four main types of Plasmodium have been identified that can infect humans: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale. Among these, malaria caused by Plasmodium falciparum is the most dangerous, leading to severe complications and even death. The spread of Plasmodium is closely related to environmental conditions in tropical and subtropical regions, where the warm and humid climate is ideal for mosquito breeding and the development of Plasmodium.

[0003] Currently, the procedure for detecting whether a patient is infected with malaria parasites is as follows: first, a lancet is used to prick the finger, then a blood-drawing tube is used to draw blood, and then the drawn blood and lysis solution are dripped into the corresponding hole of the test card. After waiting for 15 minutes, the display area of ​​the test card is observed to determine whether the patient is infected with malaria parasites. However, the entire testing process involves a lot of manual operation and is relatively slow. Therefore, we have proposed a rapid detection device for malaria parasite infection.

[0020] Example 1, please refer to Figure 1-4 This utility model provides a technical solution: a rapid detection device for Plasmodium infection, including a detection platform 1. A placement groove 2 is formed on the surface of the detection platform 1, and a detection card 3 is snapped into the placement groove 2. A timing alarm 4 is fixedly connected to the upper right corner of the surface of the detection platform 1. A finger placement groove 5 and a retention groove 6 are formed on the left side of the detection platform 1. A first electric telescopic rod 7 is fixedly installed in the retention groove 6. A blood collection needle 8 is detachably installed at the upper end of the first electric telescopic rod 7. The blood collection needle 8 can be connected to the upper end of the first electric telescopic rod 7 by snapping, thereby facilitating... The blood collection needle 8 can be replaced or disassembled and disinfected. The bottom of the finger placement groove 5 is provided with a through hole 9 corresponding to the blood collection needle 8. Two strip plates 10 are fixedly connected to the upper surface of the testing table 1. A gantry frame 11 is slidably connected to the surface of the strip plate 10. A lysis buffer adding mechanism 12 is provided on the side of the gantry frame 11. A second electric telescopic rod 13 is fixedly connected to the lower surface of the gantry frame 11. A suspension 14 is fixedly connected to the lower surface of the second electric telescopic rod 13. A blood extraction mechanism 15 and a pressing ring 16 are fixedly connected to the surface of the suspension 14.

[0021] By setting up a finger placement groove 5, a through hole 9, a first electric telescopic rod 7, and a blood collection needle 8, the first electric telescopic rod 7 can be extended and retracted to allow the blood collection needle 8 to puncture the patient's finger through the through hole 9. By setting up a second electric telescopic rod 13 to extend, the suspension 14, the blood extraction mechanism 15, and the pressing ring 16 can be moved downwards. The pressing ring 16 can be used to press the finger to facilitate the discharge of blood from the finger. The blood extraction mechanism 15 can collect the blood discharged from the finger. Then, by using the gantry frame 11 to slide on the surface of the strip plate 10, the lysis solution addition mechanism 12 and the blood extraction mechanism 15 can be moved above the test card 3. The lysis solution addition mechanism 12 discharges lysis solution into the test card 3, and the blood extraction mechanism 15 discharges the patient's blood into the test card 3. Thus, the test card 3 can be used to complete the rapid test for malaria parasites. Compared with manual operation, this test device has a high degree of automation and effectively improves the testing efficiency.

[0022] By setting a timer alarm 4, staff can be notified to observe the card 3 15 minutes after the card 3 completes the test, which effectively avoids the situation where the observation result of the card 3 is invalid due to the observation time being exceeded.

[0023] The surface of the strip plate 10 is provided with a T-shaped groove, and a T-shaped slider 17 is slidably connected in the T-shaped groove. The lower end of the gantry frame 11 is fixedly connected to the T-shaped slider 17. A third electric telescopic rod 18 is fixedly connected to the surface of the detection table 1. The telescopic end of the third electric telescopic rod 18 is fixedly connected to the lower surface of the lysis solution adding mechanism 12. By setting the T-shaped slider 17 and the T-shaped groove, the gantry frame 11 can be moved on the surface of the strip plate 10. By setting the third electric telescopic rod 18, the gantry frame 11 can be moved on the surface of the strip plate 10 by extending and retracting the third electric telescopic rod 18.

[0024] The pyrolysis solution adding mechanism 12 includes a support platform 19, a pyrolysis solution tank 20, a pump 21, and a drain pipe 22. The support platform 19 is fixedly connected to the side of the portal frame 11, the pyrolysis solution tank 20 is fixedly connected to the surface of the support platform 19, and the pump 21 is fixedly installed on the upper surface of the pyrolysis solution tank 20. The input end of the pump 21 extends to the bottom of the pyrolysis solution tank 20 through a pipe, and the output end of the pump 21 is fixedly connected to the drain pipe 22. The lower end of the drain pipe 22 is fixedly connected to the surface of the support platform 19. By setting up the pyrolysis solution adding mechanism 12, the pyrolysis solution can be conveniently contained in the pyrolysis solution tank 20. Through the operation of the pump 21, the pyrolysis solution in the pyrolysis solution tank 20 can be transported from the drain pipe 22 to the hole of the detection card 3.

[0025] The blood extraction mechanism 15 includes a support plate 23, a positive and negative fan 24, two locking seats 25, two locking plates 26, a collection cylinder 27, and an extraction tube 28. The support plate 23 is fixedly connected to the lower surface of the suspension 14 via a connecting plate. The positive and negative fan 24 is fixedly connected to the surface of the support plate 23. The two locking seats 25 are centrally symmetrically fixedly connected to the lower surface of the support plate 23. The two locking plates 26 are fixedly connected to the outer side of the upper end of the collection cylinder 27, and the locking plates 26 can engage with the locking seats 25. The extraction tube 28 is fixedly connected to the lower end of the collection cylinder 27, and the lower end face of the extraction tube 28 is coplanar with the upper surface of the pressing ring 16. The blood extraction mechanism 15, using the forward and reverse fans 24, works in the forward direction to expel the air from the collection cylinder 27. After the air is expelled from the collection cylinder 27, the negative pressure inside the collection cylinder 27 will draw blood from the extraction tube 28 into the collection cylinder 27. Once the blood has entered the collection cylinder 27, the forward and reverse fans 24 can be turned off. When the blood extraction mechanism 15 moves above the detection card 3, the forward and reverse fans 24 work in the reverse direction to deliver outside air into the collection cylinder 27. By increasing the pressure inside the collection cylinder 27, the patient's blood stored in the collection cylinder 27 can be discharged from the extraction tube 28, and finally the blood drips into the hole of the detection card 3.

[0026] By setting up the blood extraction mechanism 15, the clamping plate 26 and the clamping seat 25 can be separated by rotating the collection cylinder 27, which facilitates the disassembly and cleaning of the collection cylinder 27 and the extraction tube 28.

[0027] The surface of the testing station 1 is provided with a retrieval slot 29 that connects to the placement slot 2. By setting the retrieval slot 29, the testing card 3 can be easily taken out from the placement slot 2.

[0028] Working principle: When using this rapid malaria parasite detection device, firstly, a brand-new test card 3 is inserted into the placement slot 2, and then the fingerprint is placed face down in the finger placement slot 5. The first electric telescopic rod 7 is extended and retracted, allowing the blood collection needle 8 to puncture the patient's finger through the through hole 9. After the finger is punctured, the finger is quickly rotated 180 degrees. At this time, the second electric telescopic rod 13 extends, which can drive the suspension 14, blood extraction mechanism 15, and pressing ring 16 to move down. Pressing the finger with the pressing ring 16 facilitates the discharge of blood from the finger. The blood extraction mechanism 15 collects the discharged blood. Then, the gantry frame 11 slides on the surface of the strip plate 10, which moves the lysis buffer addition mechanism 12 and the blood extraction mechanism 15 above the test card 3. The lysis buffer addition mechanism 12 discharges lysis buffer into the test card 3, and the blood extraction mechanism 15 discharges the patient's blood into the test card 3. The rapid malaria parasite test can then be completed using the test card 3. Compared with manual operation, this detection device has a high degree of automation and effectively improves detection efficiency.
