[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] like Figures 1-8As shown, the present invention provides a portable blood routine testing device, comprising: an operating area 2 disposed within a housing 1, wherein the operating area 2 is provided with a storage section 21 for placing a sampler 3, a recycling section 22 for recycling medical waste, a detection section 23 for detecting blood samples in the sampler 3 and processing data, a controller, a power supply, and a display 24; the power supply, the display 24, and the detection section 23 are all electrically connected to the controller.

[0034] The working principle and beneficial effects of the above technical solution: This invention integrates the entire device into the housing 1 and incorporates adaptive shock absorption measures within the housing 1, making the testing device portable. When a bedridden patient needs a routine blood test, there is no need to go to the hospital. Simply open the housing 1, and take out the sampler 3, packaged in a sterile bag, from the storage section 21 in the operating area 2. Collect blood from the patient, and then place the sampler 3 containing the blood sample into the testing section 23 for testing. The test results can be displayed on the monitor 24. After the test is completed, remove the sampler 3 from the testing section 23 and place it in the recycling section 22 for centralized processing, avoiding contamination by medical waste.

[0035] The above-described structural design makes this invention small in size, lightweight, and portable, allowing for routine blood tests anytime, anywhere. This makes blood testing instruments more routine, portable, lightweight, and convenient, enabling bedridden patients who cannot easily go to the hospital to undergo routine blood tests quickly and easily.

[0036] In one embodiment, the recycling unit 22 consists of a recycling tank 25 and a recycling port 26. The recycling port 26 is provided with a one-way movable sealing plate and communicates with the side wall of a recycling box located within the recycling tank 25. A detachable transparent acrylic plate is provided at the opening of the recycling tank 25. The detection unit 23 consists of a sample retrieval port 27 and a detection device 28. The detection device 28 communicates with the sample retrieval port 27. A translation device 5, located on the detection device 28, extends into the sample retrieval port 27. A sample base 4 is provided on the translation device 5, and the sampler 3 is detachably connected to the sample base 4.

[0037] The working principle and beneficial effects of the above technical solution are as follows: When the patient places the sampler 3 in the detection unit 23, the detection device 28 is first started by the controller. Then, the translation device 5 on the detection device 28 will transport the sample base 4 in the detection device 28 to the sample storage port 27, vertically connecting the sampler 3 to the sample base 4. Then, the sampler 3 is pressed down to a horizontal state, so that the sampler 3 enters the sample storage port 27. After that, the sample base 4 is translated and reset along the translation device 5. Then, the relevant equipment in the detection device 28 will detect the blood sample. The detection equipment is existing technology. According to the product model of the present invention, different detection methods can be equipped with corresponding detection equipment. For example, the laser scattering method requires the relevant light source, sheath flow, photodetector and other equipment. The specific detection methods and corresponding equipment will not be described in detail.

[0038] After the test is completed, the translation device 5 transports the sample base 4 with the sampler 3 to the sample storage port 27 again, removes the sampler 3 from the sample base 4 and puts it into the recycling port 26. The sampler 3 will enter the recycling box of the recycling tank 25 through the recycling port 26. When medical waste is centrally processed, the recycling box can be taken out by removing the acrylic plate from the opening of the recycling tank 25.

[0039] The above-described structure allows the operator to be separated from the detection device 28 and medical waste, preventing the operator from directly operating the detection device 28 and causing equipment damage, while also preventing medical waste from causing environmental pollution.

[0040] In one embodiment, the sample base 4 includes a fixed disk 41 disposed on the translation device 5 and a flipping device connected to the fixed disk 41 via a support platform 42; the sampler 3 is detachably connected to the flipping device. The flipping device consists of a U-shaped positioning member 43 and a movable rod 44; the sidewall of the positioning member 43 is symmetrically provided with an arc-shaped movable groove and a rotating shaft hole, and the movable rod 44 is symmetrically provided with two rotating rods 45a and 45b and two limiting rods 46a and 46b.

[0041] The rotating rods 45a and 45b are movably connected to the positioning member 43 through the rotating shaft hole. One end of the rotating rod 45a is provided with a toothed positioning wheel 47, which is connected to the outer side wall of the positioning member 43.

[0042] The two limiting rods 46a and 46b are respectively located in the two movable slots. One of the limiting rods 46a is connected to a limiting gear 48 that meshes with the toothed positioning wheel 47. The limiting gear 48 is located on the outer wall of the positioning member 43.

[0043] The limiting rods 46a and 46b are threadedly connected to the movable rod 44. A handle 49 is provided at the end of the limiting rod 46b on the side away from the limiting gear 48. A supporting rotating shaft 421 is provided on the supporting platform 42. The top of the supporting rotating shaft 421 is connected to the bottom surface of the positioning member 43. The bottom of the supporting rotating shaft 421 is connected to the fixed plate 41 through a bearing. The side wall of the supporting rotating shaft 421 is movably connected to the supporting platform 42. A rotary motor is provided at the bottom of the fixed plate 41. The output end of the rotary motor is connected to the bottom of the supporting rotating shaft 421. When the limiting rods 46a and 46b are located at the bottom of the movable groove, the distance H between their central axis and the inner bottom surface of the positioning member 43 is less than the distance D between the central axis of the rotating rods 45a and 45b and the inner bottom surface of the positioning member 43.

[0044] The working principle and beneficial effects of the above technical solution: When patients undergo blood tests, sometimes the purpose of the test is only to detect certain indicators of whole blood, while other times it is necessary to separate serum and plasma by centrifugation before certain indicators can be detected. Therefore, in order to meet the different needs of patients, this embodiment provides two implementation methods: non-centrifugation and centrifugation, to meet the needs of patients.

[0045] In this non-centrifugal type embodiment, there is no need to set up a handle 49 or other structures. It is sufficient that the sampler 3 can be flipped from vertical to horizontal so that it can enter the detection device 28 from the sample storage port 27.

[0046] After sampler 3 is installed, it is pushed. At this time, movable rod 44 will rotate around rotating rods 45a and 45b. Limiting rods 46a and 46b move along the movable groove from the top to the bottom. While limiting rods 46a and 46b are moving, limiting gear 48 moves along toothed positioning wheel 47. Then, translation device 5 drives sample base 4 to be translated into detection device 28 for detection.

[0047] In this centrifugal type embodiment, the principle of sampler 3 flipping is the same as that of the non-centrifugal type. The difference is that when the limiting rods 46a and 46b move to the bottom of the movable groove, the distance H between the central axis of the limiting rods 46a and 46b and the inner bottom surface of the positioning member is less than the distance D between the central axis of the rotating rods 45a and 45b and the inner bottom surface of the positioning member 43. This makes the sampler 3 non-horizontal after flipping, but at an angle to the horizontal plane. Then, the handle 49 is rotated to form a fixed connection between the positioning member 43 and the movable rod 44. It should be noted that the handle 49 can be set on one side of the limiting rod 46b or on one side of the limiting rod 46a. At the same time, the limiting rods 46a and 46b can be fixed by using hexagonal bolts, and can be fixed by tightening the hexagonal handle when fixation is required. The limiting gear 48 can facilitate the adjustment and limiting of the angle of the movable rod 44.

[0048] Subsequently, the sample base 4 returns to the detection device 28, and the rotary motor at the bottom of the fixed plate 41 starts, driving the positioning component 43 to rotate through the support shaft 421, thereby causing the sampling tube 3 to undergo centrifugation.

[0049] Through the design of the above mechanism, because H is less than D, the sampling tube 3 can have an angle with the horizontal plane, which facilitates centrifugation operation. At the same time, it will not occupy a particularly large area, thereby reducing the size of the invention. Furthermore, the invention can be configured with different implementation methods according to the different needs of patients. For patients with low requirements for detection indicators, a non-centrifugation implementation method can be provided to save production costs and reduce production difficulty, thereby reducing the user's purchase cost.

[0050] In one embodiment, the sampler 3 includes a tube body 31 and a tube cap 32; the inner wall of the tube body 31 is divided by a partition 33 to form a sampling tube 34 with an opening at the top of the tube body 31 and a puncture tube 35 with an opening at the bottom of the tube body 31, the tube cap 32 is disposed on the opening of the sampling tube 34 and is threadedly connected to the sampling tube 34, the puncture tube 35 is provided with an elastic block with a needle, the tube body 31 located at the puncture tube 35 is made of elastic material, and the tube cap 32 is detachably connected to the end of the movable rod 44.

[0051] The cap 32 is provided with a groove extending into the sampling tube 34, and the end of the movable rod 44 is inserted into the groove.

[0052] The top of the cap 32 is provided with a locking platform 321 and a quick-release head 6. The quick-release head 6 is provided with a plurality of insertion slots 61. The locking platform 321 is inserted into the insertion slots 61. The quick-release head 6 is connected to the top of the cap 32 through the cooperation of the locking platform 321 and the insertion slots 61. The end of the movable rod 44 is provided with a connector 7. The quick-release head 6 and the connector 7 are detachably connected.

[0053] The bottom surface of the connector 7 is connected to the top surface of the movable rod 44. A connecting post 71 is provided on the top surface of the connector 7. A limiting platform 72 extending outward is provided on the top of the connecting post 71. A plurality of receiving grooves 73 are provided on the outer side wall of the connecting post 71 and the limiting platform 72. A first slide 74 is also provided along the outer side wall of the connecting post 71. The two ends of the first slide 74 are located on the top surface and the bottom surface of the connecting post 71, respectively.

[0054] The quick-release head 6 is provided with a positioning ring 62. The inner diameter of the positioning ring 62 is adapted to the outer diameter of the connecting post 71. The inner wall of the positioning ring 62 is provided with a plurality of retaining strips 63 and a second slide 64. The two ends of the second slide 64 are respectively located on the top surface and the bottom surface of the positioning ring 62. The first slide 74 is adapted to the second slide 64.

[0055] The working principle and beneficial effects of the above technical solution: This embodiment provides a sampler 3. The sampler 3 adopts an integrated design for easy carrying. When using it, you only need to pinch the outer wall of the puncture tube 35 to squeeze the elastic block, thereby squeezing the needle out of the puncture tube 35 to facilitate the patient to puncture the distal end for blood collection.

[0056] The sampler 3 is also equipped with a blood collection tip. One end of the blood collection tip can be directly installed at the opening of the sampling tube 34, or it can be directly inserted into the groove of the tube cap 32 (if this method is used, the blood collection tip needs to have a piercing end for piercing the groove of the tube cap 32, and the inner bottom surface of the groove needs to be made of an easily pierced material). Squeeze the sampling tube 34, place the blood collection tip on the blood droplet at the tip, and release the sampling tube 34. Under negative pressure, blood can be drawn into the sampling tube 34. After blood collection, remove the blood collection tip, place it in the collection section 22 for recycling, and replace the tube cap 32. If the tube cap 32 is pierced, the blood collection tip needs to be removed and the quick-release head 6 installed to seal the tube cap 32.

[0057] The above-described structure allows for the integrated design of the sampler 3, enabling centralized collection of the needle and sampling tube, thus preventing contamination from medical waste.

[0058] This embodiment also provides four ways to connect the sampler 3 to the movable rod 44.

[0059] The first implementation method is as follows: the blood collection tip adopts a non-piercing groove design, and the groove of the cap 32 can be inserted into the movable rod 44 to achieve fixation. This implementation method has the simplest structure, but it is only suitable for non-centrifugal blood testing.

[0060] The second implementation method, such as Figure 7 As shown in A: The blood sampling tip can be implemented in two ways: by piercing the groove or not. The quick-release tip 6 and the tube cap 32 are connected by interlocking the locking plate 321 and the insertion slot 61. If the blood sampling tip is used to pierce the groove for blood sampling, the tube cap 32 can seal the groove. Then the quick-release tip 6 and the connector 7 are connected to complete the fixation.

[0061] The third implementation method, such as Figure 7 As shown in B: The blood collection tip can be implemented in two ways: by piercing the groove or not. The quick-release tip 6 and the tube cap 32 are connected by a stud thread connection. If the blood collection tip is used to collect blood by piercing the groove, the stud on the tube cap 32 can seal the groove. Then the quick-release tip 6 and the connector 7 are connected to complete the fixation.

[0062] The fourth implementation method, such as Figure 7 As shown in C: The blood sampling tip can only be implemented without piercing the groove. The card holder 321 is placed at the opening of the piercing tube 35, and the quick-release head 6 is connected to the piercing tube 35. In this implementation, the needle can be sealed to prevent accidental injury when installing or removing the sampler 3. Correspondingly, this implementation requires an additional circular motion track and drive motor on the fixed plate 41. That is, after the sampler 3 is installed, the angle of the sampler 3 is adjusted so that the opening of the sampling tube 34 is higher than the opening of the piercing tube 35. Then, the sample base 4 is moved to the circular motion track by the translation device 5. Then, the drive motor drives the sampler 3 to move quickly along the circular motion track, keeping the opening of the sampling tube 34 always on the axis of the center of the circular motion track for centrifugation. The drive motor is also electrically connected to the controller.

[0063] When the quick-release head 6 and the connector head 7 are connected, the first slide 74 and the second slide 64 are adjusted to a mutually compatible position. At this time, the end of the locking strip 63 is exactly compatible with the guide groove 73. As the quick-release head 6 and the connector head 7 rotate relative to each other, the locking strip 63 enters the lower part of the limiting stage 72 along the guide groove 73, thereby realizing the quick engagement of the sampler 3 and the movable rod 44.
