Description

Technical Field

[0001] The present invention belongs to the technical field related to blood sampling, and more specifically, particularly relates to a blood sampling device for a laboratory based on a disinfection control mechanism. Background Art

[0002] The laboratory is a bridge between clinical medicine and basic medicine, including clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, and blood transfusion. When a small amount of blood is taken from the examinee for individual tests due to inspection or related needs, fingertip sampling is often used, requiring medical personnel to use a puncture needle to puncture the examinee's fingertip. Manually holding the puncture needle for acupuncture cannot guarantee the precise puncture site and depth. However, the blood sampling technology in the prior art has the following defects: In the prior art, the current fingertip blood collection method mostly uses a blood collection needle to puncture the finger, then uses a thin tube to squeeze the blood from the wound, and then samples it into a container for storage. It requires multiple steps to sample the blood between the fingers, which is inconvenient.

[0003] In the prior art, after the blood collection device in the laboratory uses a blood collection needle to puncture the finger, a disinfectant is usually sprayed on the blood collection needle for disinfection. It is difficult to quickly and completely disinfect and clean the blood on the blood collection needle, which affects the reuse of the blood collection needle.

[0004] In the prior art, in order to improve the efficiency of finger blood collection, the blood collection device of the laboratory usually directly punctures the finger and absorbs the blood into a round tube for storage, so the round tube needs to be disinfected in time so that the round tube can be reused to store blood.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The blood sampling device for the laboratory based on the disinfection control mechanism of the present invention, through the setting of the slide bar, the positioning ring, and the fourth spring, the staff pushes the housing and the first disc to move downward, and the positioning ring is pressed by the fingertips of the examinee to cooperate with the downward movement of the first disc, so that the four slide bars slide on the first disc, so that the first disc moves downward steadily. And the first disc moves downward to cooperate with the positioning ring to fix, so as to compress the fourth spring to generate elastic force, and under the elastic force of the fourth spring, the first disc is further moved downward steadily, which is conducive to the blood collection needle to stably puncture the fingertips of the examinee.

[0018] The blood sampling device for the laboratory based on the disinfection control mechanism of the present invention is characterized in that the rotation of the round rod drives the third disc to rotate, the rotation of the third disc drives the rotation of the round rod, the rotation of the round rod drives the two curved plates and the wiping member to rotate, and the two wiping members rotate to cooperate with the disinfectant sprayed by the first spray valve to perform a rotational wiping and disinfection effect on the outside of the blood collection needle. Then, through the arrangement of the first spray valve, the guide block, and the first push rod, the round ring continues to move upward so that the upper side of the movable ring is supported by the first cover plate, so that the two guide blocks move downward in the two slide grooves respectively. The two guide blocks move downward because the side where the two guide blocks are close to each other is an inclined structure, and the two guide blocks move downward. Under the guiding effect of the inclined surfaces of the two guide blocks, the two first push rods are close to each other. The two first push rods are close to each other, driving the two curved plates and the wiping member to approach each other, thereby gradually increasing the degree of wiping contact between the two wiping members and the blood collection needle, and improving the wiping and disinfection effect of the disinfection component on the blood collection needle. Then, through the arrangement of the protrusions and the first spring, under the guiding action of several pairs of protrusions and the elastic force of the two first springs, the two first push rods move back and forth slightly in the process of approaching each other in a large range. The small back and forth movement of the first push rods drives the arc plate and the wiping member to move back and forth slightly. The small back and forth movement of the wiping member cooperates with the disinfectant sprayed upward by the first spray valve, so that the impurities just wiped off can be quickly sprayed out from the inner wall of the ring by the disinfectant, and the wiping member can be disinfected and cleaned in time, thereby extending the service life of the wiping member and improving the effect of wiping and disinfecting the blood collection needle by the wiping member. Finally, through the setting of the V-shaped elastic part and the second push rod, the two guide blocks move downward to extrude and deform the two V-shaped elastic parts. The deformation of the two V-shaped elastic parts pushes the two second push rods to approach each other. The two second push rods approach each other and drive the lower ends of the two arc plates to rotate and approach each other. Therefore, in the process of the ring moving upward, the degree of wiping contact between the two wiping parts and the blood collection needle is gradually further improved, thereby further improving the wiping and disinfection effect of the disinfection assembly on the blood collection needle.

[0019] The blood sampling device for the laboratory based on the disinfection control mechanism of the present invention is configured such that the disinfectant in the third disc is sprayed into the inner wall of the circular ring through the first spray valve, thereby performing a disinfectant spray cleaning effect on the blood collection needle. Then, through the configuration of the second spray valve, the two circular tubes correspond to a plurality of pairs of second spray valves up and down, thereby utilizing a plurality of pairs of second spray valves to spray the disinfectant in the third disc into the two circular tubes, so that the disinfectant enters the two storage chambers respectively through the two circular tubes, thereby being able to perform a flushing and disinfecting effect on the inside of the two circular tubes and the inside of the two storage chambers. Finally, through the configuration of the third spray valve, the disinfectant in the annular disc is sprayed upwardly through a plurality of third spray valves, thereby allowing the disinfectant to be concentratedly sprayed onto the outside of the blood collection needle and the two circular tubes, thereby performing a disinfectant spraying and disinfecting effect on the outside of the blood collection needle and the two circular tubes in an all-round manner.

[0037] Preferably, see Attachment Figure 1 , Attachment Figure 2 , Attachment Figure 4 A plurality of rubber rings 16 are provided at intervals on the outer wall of the housing 10, a limit plate 30 is fixedly provided on the outer wall of the round rod 13, a third spring 31 is connected between the upper side of the limit plate 30 and the inner upper side of the second disc 12, a plurality of slide rods 17 are slidably provided on the first disc 11, a positioning ring 18 is fixedly provided at one end of the plurality of slide rods 17, a plurality of fourth springs 19 are connected between one side of the positioning ring 18 and the outer side of the first disc 11, and the fourth spring 19 is wound around the outer wall of the slide rod 17.

[0038] Specific use of the present invention: When blood is collected from the fingertips, first, the staff member presses the positioning ring 18 on the fingertips of the person being examined, and then pushes the housing 10 and the first disc 11 downward. The positioning ring 18 is pressed against the fingertips of the person being examined to cooperate with the downward movement of the first disc 11, so that the four slide bars 17 slide on the first disc 11, and the first disc 11 moves downward steadily. The first disc 11 moves downward to cooperate with the positioning ring 18 to fix, thereby compressing the fourth spring 19 to generate elastic force. Under the elastic force of the fourth spring 19, the first disc 11 is further moved downward steadily, which is conducive to the blood collection needle 14 to stably puncture the fingertips of the person being examined.

[0039] At the same time, the lower end of the circular tube 15 is pressed by the fingertips of the examinee, so that the circular tube 15 slides in the storage chamber 21. The circular tube 15 slides into the storage chamber 21 to avoid affecting the blood collection needle 14 from piercing the fingertips of the examinee. The sliding of the circular tube 15 drives the slider 22 to slide, and the sliding of the slider 22 compresses the second spring 23 to generate elastic force, and the circular tube 15 can be moved and reset under the elastic force of the second spring 23. The slider 22 slides in the storage chamber 21, and the sliding of the slider 22 compresses and folds one of the folding parts 24, and the sliding of the slider 22 stretches the other folding part 24, so that the slider 22 can slide smoothly in the storage chamber 21 to avoid the solution in the storage chamber 21 from contacting the second spring 23.

[0040] Then, the fingertips of the examinee are punctured, and the elastic force generated by the compression of the fourth springs 19 acts on the positioning ring 18, thereby squeezing the fingertips of the examinee. The staff pushes the housing 10 and the first disc 11 upward, and the circular tube 15 slides under the elastic force of the second spring 23. The circular tube 15 slides so that the lower end of the circular tube 15 is lower than the lower end of the blood collection needle 14, so that the lower end of the circular tube 15 can contact the blood on the fingertips of the examinee. At this time, the staff pulls the operating rod 28 to move upward, and the upward movement of the operating rod 28 drives the piston plate 27 to move upward. The piston plate 27 moves upward in the piston cavity 26, so that negative pressure is generated in the piston cavity 26, and the blood on the fingertips of the examinee is absorbed into the two storage cavities 21 through the two connecting channels 25, the storage cavity 21, and the circular tube 15, thereby improving the efficiency of blood sampling and storage.

[0041] Finally, the staff member drives the round rod 13 upward through the circular plate 20, and the upward movement of the round rod 13 drives the blood collection needle 14 and the two circular tubes 15 to move upward to the top of the first disc 11. The control system controls the first stepper motor 35 to start, and the first stepper motor 35 starts to drive the rotating plate 32 to rotate, and the rotating plate 32 rotates to drive one of the storage cylinders 73 to move below the round rod 13. The first stepper motor 35 stops, and the staff member pushes the round rod 13 to move downward so that the lower ends of the two circular tubes 15 enter the storage cylinder 73 through the two connecting valves 75 respectively. The staff member pushes the operating rod 28 to move downward, and the operating rod 28 moves downward to drive the piston plate 27 to move downward. The piston plate 27 moves downward to transport the blood in the storage chamber 21 through the circular tube 15 to the storage cylinder 73 for temporary storage, thereby realizing self-service sampling and storage of blood. Among them, the upward movement of the round rod 13 drives the limit plate 30 to move upward, and the limit plate 30 moves upward to compress the third spring 31 to generate elastic force.

[0042] When performing disinfection, first, the staff drives the round rod 13 upward through the circular plate 20, and the round rod 13 moves upward to drive the blood collection needle 14 and the two round tubes 15 to move upward to the top of the first disc 11. The control system controls the first stepper motor 35 to start, and the first stepper motor 35 starts to drive the rotating plate 32 to rotate, and the rotating plate 32 rotates to drive the disinfection cylinder 38 to move below the round rod 13. The first stepper motor 35 stops, and the staff releases the round rod 13. Under the elastic force of the third spring 31, the limit plate 30 and the round rod 13 move downward, and the round rod 13 moves downward to allow the blood collection needle 14 to pass through the first through hole 40 and enter the disinfection cylinder 38; and the lower ends of the two round tubes 15 pass through the two second through holes 41 respectively and enter the disinfection cylinder 38. The control system controls the disinfectant in the first annular cylinder 29 to enter the disinfectant water chamber 36 through the connecting pipe 34, the disinfectant in the disinfectant water chamber 36 to enter the third annular cylinder 43 through the fixed pipe 60, the disinfectant in the third annular cylinder 43 to enter the third disc 42 through the telescopic connecting pipe 62, and the disinfectant in the third disc 42 to enter the annular disc 44 through the connecting port 58. The disinfectant in the third disc 42 is first sprayed into the inner wall of the ring 45 through the first spray valve 55, thereby spraying and cleaning the blood collection needle 14. Then, the two circular tubes 15 correspond to the plurality of pairs of second spray valves 56 up and down, so that the disinfectant in the third disc 42 is sprayed into the two circular tubes 15 by the plurality of pairs of second spray valves 56, so that the disinfectant enters the two storage chambers 21 through the two circular tubes 15 respectively, so that the inside of the two circular tubes 15 and the inside of the two storage chambers 21 can be rinsed and disinfected. Finally, the disinfectant in the annular disk 44 is sprayed upwardly through a plurality of third spray valves 57, so that the disinfectant is concentratedly sprayed to the outside of the blood collection needle 14 and the two round tubes 15, thereby comprehensively spraying and disinfecting the outside of the blood collection needle 14 and the two round tubes 15. Among them, the rotation of the rotating plate 32 drives the disinfection cylinder 38 to rotate, the rotation of the disinfection cylinder 38 drives the fixed tube 60 to rotate, and the rotation of the fixed tube 60 drives the first annular member 59 to slide in an annular manner in the inner wall of the second annular cylinder 33, so that when the fixed tube 60 moves to one side of the disinfection water chamber 36, the interior of the third annular cylinder 43 is connected to the disinfection water chamber 36 through the fixed tube 60. And when the fixed tube 60 moves to one side of the recovery chamber 37, the interior of the third annular cylinder 43 is connected to the interior of the recovery chamber 37 through the fixed tube 60.

[0043] Secondly, the control system controls the second stepper motor 63 to start, and the second stepper motor 63 starts to drive the second gear 64 to rotate, and the outer side of the second gear 64 meshes with the outer side of the first gear 70, and the second gear 64 rotates to drive the first gear 70 to rotate. The first slider 68 slides axially on the inner wall of the first gear 70 to cooperate with the first slider 68 and the round rod 65 to be fixedly connected, so that the first slider 68 plays a spline role. The first gear 70 rotates through the first slider 68 to drive the round rod 65 to rotate, and the round rod 65 rotates to drive the first slider 68 and the second slider 69 to rotate. The second slider 69 rotates and slides in the two arc-shaped slide grooves 67. The second slider 69 is guided by the arc-shaped slide grooves 67, so that the second slider 69 moves up and down, and the second slider 69 moves up and down to drive the first slider 68 and the round rod 65 to move up and down, so that the round rod 65 rotates and moves up and down.

[0044] Then, the round rod 65 moves upward to drive the third disc 42 to move upward, and the third disc 42 moves upward to allow the blood collection needle 14 to enter the inner wall of the ring 45. At this time, the rotation of the round rod 65 drives the third disc 42 to rotate, and the rotation of the third disc 42 drives the ring 45 to rotate, and the rotation of the ring 45 drives the two arc plates 48 and the wiper 46 to rotate, and the two wipers 46 rotate to cooperate with the disinfectant sprayed by the first spray valve 55 to perform a rotational wiping and disinfection effect on the outside of the blood collection needle 14. Among them, the upward movement of the third disc 42 stretches the telescopic connecting tube 62, and the rotation of the third disc 42 drives the second annular member 61 to slide in an annular manner on the upper side of the third annular cylinder 43 through the telescopic connecting tube 62, so that the interior of the third disc 42 is connected with the interior of the third annular cylinder 43.

[0045] Then, the circular ring 45 continues to move upward so that the upper side of the movable ring 50 is supported by the first cover plate 39, so that the two guide blocks 51 move downward in the two slide grooves 76 respectively. The two guide blocks 51 move downward because the side close to each other is in an inclined structure, and the two guide blocks 51 move downward, and under the guiding action of the inclined surfaces of the two guide blocks 51, the two first push rods 47 approach each other. The two first push rods 47 approach each other, driving the two arc plates 48 and the wiper 46 to approach each other, thereby gradually increasing the degree of wiping contact between the two wipers 46 and the blood collection needle 14, and improving the disinfection effect of the wiping and disinfection assembly on the blood collection needle 14.

[0046] At the same time, the two guide blocks 51 move downward, driving the pairs of protrusions 52 to move downward. The pairs of protrusions 52 move downward to squeeze one end of the two first push rods 47, so that the two first push rods 47 move closer to each other. The two first push rods 47 move closer to each other to stretch the two first springs 49 to generate elastic force. When one end of the two first push rods 47 is out of contact with the two protrusions 52, the two first push rods 47 move away from each other slightly under the elastic force of the two first springs 49. So that under the guiding action of the several pairs of protrusions 52 and the elastic force of the two first springs 49, the two first push rods 47 can move back and forth slightly in the process of approaching each other in a large range. The small back and forth movement of the first push rods 47 drives the arc plate 48 and the wiping member 46 to move back and forth slightly. The small back and forth movement of the wiping member 46 cooperates with the disinfectant sprayed upward by the first spray valve 55, so that the impurities just wiped off can be quickly sprayed out from the inner wall of the ring 45 by the disinfectant, and the wiping member 46 can be disinfected and cleaned in time, thereby extending the service life of the wiping member 46 and improving the effect of wiping and disinfecting the blood collection needle 14 by the wiping member 46.

[0047] At the same time, the two guide blocks 51 move downward to squeeze and deform the two V-shaped elastic members 53. The deformation of the two V-shaped elastic members 53 pushes the two second push rods 54 to approach each other. The two second push rods 54 approach each other and drive the lower ends of the two arc plates 48 to rotate and approach each other. As a result, in the process of the ring 45 moving upward, the degree of wiping contact between the two wiping members 46 and the blood collection needle 14 is gradually further improved, further improving the wiping and disinfection effect of the disinfection assembly on the blood collection needle 14.

[0048] Finally, after the blood collection needle 14, the two round tubes 15 and the two storage chambers 21 are fully disinfected, the staff drives the round rod 13 upward through the circular plate 20, and the upward movement of the round rod 13 drives the blood collection needle 14 and the two round tubes 15 to move upward to the top of the first disc 11, and the control system controls the first stepper motor 35 to start, and the first stepper motor 35 starts to drive the rotating plate 32 to rotate, and the rotating plate 32 rotates to drive the positioning hole 77 to move to the bottom of the round rod 13, and the first stepper motor 35 stops so that it can be reused.

[0049] The blood sampling device for the laboratory based on the disinfection control mechanism of the present invention, through the setting of the slide bar 17, the positioning ring 18, and the fourth spring 19, the staff pushes the housing 10 and the first disc 11 to move downward, and the positioning ring 18 is pressed by the fingertips of the examinee to cooperate with the downward movement of the first disc 11, so that the four slide bars 17 slide on the first disc 11, so that the first disc 11 moves downward steadily. And the first disc 11 moves downward to cooperate with the positioning ring 18 to fix, so as to compress the fourth spring 19 to generate elastic force, and under the elastic force of the fourth spring 19, the first disc 11 is further moved downward steadily, which is conducive to the blood collection needle 14 to stably puncture the fingertips of the examinee.

[0050] The blood sampling device for the laboratory based on the disinfection control mechanism of the present invention, through the ring 45, the arc plate 48, and the wiper 46, the round rod 65 rotates to drive the third disc 42 to rotate, the third disc 42 rotates to drive the ring 45 to rotate, the ring 45 rotates to drive the two arc plates 48 and the wiper 46 to rotate, and the two wipers 46 rotate to cooperate with the disinfectant sprayed by the first spray valve 55 to perform a rotational wiping and disinfection effect on the outside of the blood collection needle 14. Then, through the setting of the first spray valve 55, the guide block 51, and the first push rod 47, the ring 45 continues to move upward so that the upper side of the movable ring 50 is resisted by the first cover plate 39, so that the two guide blocks 51 move downward in the two slide grooves 76 respectively. The two guide blocks 51 move downward because the side close to each other is an inclined structure, and the two guide blocks 51 move downward. Under the inclined guiding effect of the two guide blocks 51, the two first push rods 47 are close to each other. The two first push rods 47 approach each other, driving the two arc plates 48 and the wiper 46 to approach each other, thereby gradually increasing the degree of wiping contact between the two wipers 46 and the blood collection needle 14, and improving the wiping and disinfecting effect of the disinfection assembly on the blood collection needle 14. Then, through the setting of the protrusion 52 and the first spring 49, under the guiding effect of several pairs of protrusions 52 and the elastic effect of the two first springs 49, the two first push rods 47 move back and forth slightly in the process of approaching each other in a large range, and the small back and forth movement of the first push rod 47 drives the arc plate 48 and the wiper 46 to move back and forth slightly. The small back and forth movement of the wiper 46 cooperates with the disinfectant sprayed upward by the first spray valve 55, and the impurities just wiped can be sprayed out from the inner wall of the ring 45 quickly by the disinfectant spray, and the wiper 46 can be disinfected and cleaned in time, extending the service life of the wiper 46, and improving the wiping and disinfecting effect of the wiper 46 on the blood collection needle 14. Finally, through the setting of the V-shaped elastic member 53 and the second push rod 54, the two guide blocks 51 move downward to squeeze and deform the two V-shaped elastic members 53. The deformation of the two V-shaped elastic members 53 pushes the two second push rods 54 to approach each other. The two second push rods 54 approach each other and drive the lower ends of the two arc plates 48 to rotate and approach each other. Therefore, in the process of the ring 45 moving upward, the degree of wiping contact between the two wiping members 46 and the blood collection needle 14 is gradually further improved, thereby further improving the wiping and disinfection effect of the disinfection assembly on the blood collection needle 14.

[0051] In the blood sampling device for the laboratory based on the disinfection control mechanism of the present invention, the disinfectant in the third disc 42 is sprayed into the inner wall of the ring 45 through the first spray valve 55 through the setting of the first spray valve 55, so that the blood collection needle 14 is sprayed with the disinfectant to clean it. Then, through the setting of the second spray valve 56, the two circular tubes 15 correspond to the plurality of pairs of second spray valves 56 up and down, so that the disinfectant in the third disc 42 is sprayed into the two circular tubes 15 by the plurality of pairs of second spray valves 56, so that the disinfectant enters the two storage chambers 21 through the two circular tubes 15 respectively, so that the inside of the two circular tubes 15 and the inside of the two storage chambers 21 can be flushed and disinfected. Finally, through the setting of the third spray valve 57, the disinfectant in the annular disc 44 is sprayed upwardly through the plurality of third spray valves 57, so that the disinfectant is concentratedly sprayed to the outside of the blood collection needle 14 and the two circular tubes 15, so that the disinfectant spraying and disinfecting effect is performed on the outside of the blood collection needle 14 and the two circular tubes 15 in an all-round manner.
