Description

Technical Field

[0001] The invention relates to the technical field of gold mark penetration detection, in particular to an automatic sampling gold mark penetration detection device. Background Art

[0002] In medical testing scenarios, fingertip blood collection is a common sampling method for blood sugar monitoring, initial disease screening, and other purposes. Its ease of operation is crucial for family health management and personal daily testing. Traditional fingertip blood collection is often performed manually by medical staff, and there are many factors that make it unsuitable for users to operate independently: First, it is difficult to accurately control the pressure during blood collection. Ordinary people lack professional training and can easily cause poor blood flow due to insufficient pressure or tissue damage due to excessive pressure. Second, the manual operation process is complex, and every step from disinfection to needle insertion requires strict regulations. The slightest negligence when the user operates independently may lead to risks such as infection, and it is difficult to guarantee the accuracy and effectiveness of blood collection.

[0003] While some automated blood collection devices have emerged with the increasing popularity of home medical devices, they still present significant drawbacks when operated by the user. Some automated blood collection devices fail to adequately consider the user's operational convenience during self-collection. The inability to effectively secure the finger before blood collection makes it difficult to control the angle and depth of needle insertion, reducing the success rate and potentially causing accidental injury. Furthermore, the lack of a proper fingertip compression design makes self-collection painful and difficult to obtain, impacting subsequent testing procedures. Summary of the Invention

[0004] The purpose of the present invention is to provide a gold label penetration detection device with automatic sampling, which solves the problem that users of existing detection cards have to draw blood and test components by themselves.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-8 , this embodiment provides a technical solution: an automatic sampling gold label penetration detection device, including an installation box 100, two arc-shaped pressure blocks 120 are symmetrically hinged on both sides of the box opening of the installation box 100, and two pressure strips 150 are symmetrically slidably connected on both sides of the box opening of the installation box 100. When the two arc-shaped pressure blocks 120 approach each other, the two pressure strips 150 synchronously squeeze the fingertips; a needle 220 is linearly slidably connected to the middle part of the installation box 100, and the needle 220 is facing the fingertips. After the two pressure strips 150 synchronously squeeze the fingertips, the needle 220 vertically reciprocates for a stroke to puncture the fingertips for sampling.

[0032] During use, after disinfecting the finger, place the fingertip between the two arc-shaped pressing blocks 120 so that the fingertip is between the two pressure strips 150, and control the two arc-shaped pressing blocks 120 to approach each other. The two arc-shaped pressing blocks 120 fix the nail part of the finger and push the fingertip to approach between the two pressure strips 150. At the same time, the two pressure strips 150 approach each other to squeeze the two sides of the fingertip, so that the pain of subsequent acupuncture of the fingertip is reduced. Then the needle 220 moves toward the fingertip, pierces the fingertip, and completes the fingertip blood sampling operation. Therefore, this device can facilitate the user to collect blood by himself, making the blood collection process more convenient.

[0033] The installation box 100 has mounting plates 110 symmetrically hinged on both sides of the box opening, and a rectangular rod 140 is fixedly connected to the pressure strip 150. The rectangular rod 140 passes through and slides on the box wall of the installation box 100. The two arc-shaped pressure blocks 120 are respectively connected to the two mounting plates 110. When the two mounting plates 110 swing so that the two arc-shaped pressure blocks 120 approach each other, the mounting plates 110 are synchronously driven by the rectangular rod 140 to make the two pressure strips 150 approach each other.

[0034] The installation box 100 is placed at the bottom so that the installation plate 110 is at the top. After placing your fingers on the box opening of the installation box 100, pinch the two installation plates 110 close to each other with your other hand. The installation plates 110 drive the two arc-shaped pressing blocks 120 close to each other. At the same time, the installation plates 110 push the rectangular rod 140, so that the two pressure strips 150 are close to the fingertips at the same time.

[0035] A reinforcement frame 130 is also connected to the box wall of the installation box 100, and a rectangular rod 140 is inserted into the middle of the reinforcement frame 130. Two turntables 230 are rotatably connected inside the installation box 100, and the two turntables 230 are located on the same axis, and an eccentric rod 240 is connected between the two turntables 230; a slide 200 is fixedly connected inside the installation box 100, and a mounting rod 210 is slidably connected inside the slide 200, and the needle 220 is threadedly connected to the mounting rod 210. The bottom end of the mounting rod 210 is connected to a hollow bar 250, and the eccentric rod 240 slides on the hollow bar 250. The two turntables 230 rotate synchronously so that the eccentric rod 240 can drive the mounting rod 210 to move axially back and forth when sliding on the hollow bar 250.

[0036] The mounting rod 210 and the axis of the rotating disk 230 are perpendicular to each other, and the hollow bar 250 is arranged horizontally;

[0037] After the fingertip is pressed by the pressure strip 150, the turntable 230 rotates. At this time, the eccentric rod 240 slides in the hollow bar 250, and the mounting rod 210 is limited by the slide 200. Therefore, the rotation of the turntable 230 can drive the mounting rod 210 to slide axially back and forth, and then the mounting rod 210 drives the needle 220 to approach the fingertip for acupuncture and then move away from the fingertip.

[0038] A rotating shaft 231 is rotatably connected inside the installation box 100, and two turntables 230 are coaxially connected to the rotating shaft 231. A mounting ring 260 is fixedly connected to the inner wall of the installation box 100, and the rotating shaft 231 is coaxially inserted into the mounting ring 260. A torsion spring 261 is connected between the rotating shaft 231 and the mounting ring 260. The torsion spring 261 can drive the rotating shaft 231 to rotate reciprocatingly after storing and releasing force.

[0039] In the initial state, the shaft 231 rotates to give the torsion spring 261 a torsion force, and then the shaft 231 is locked. When the shaft 231 is unlocked, the torsion force of the torsion spring 261 is released, allowing the shaft 231 to rotate, thereby driving the turntable 230 to rotate, so that the needle 220 can prick the fingertips.

[0040] A piston cylinder 270 is fixedly connected to the inner wall of the installation box 100 , a round piston rod 271 is slidably connected inside the piston cylinder 270 , and a slot that cooperates with the round piston rod 271 is opened on the side wall of the rotating shaft 231 .

[0041] A piston plate is provided at the end of the round piston rod 271. After air is injected into the space of the round piston rod 271 by the piston plate in the piston cylinder 270, the round piston rod 271 can be retracted into the piston cylinder 270. At this time, the round piston rod 271 pulls out the rotating shaft 231, thereby unlocking the rotating shaft 231. At this time, the torque of the torsion spring 261 is released, thereby driving the turntable 230 to rotate.

[0042] A rectangular cavity is opened at the end of one of the rectangular rods 140, and a rectangular piston rod 280 is slidably connected in the rectangular cavity. The end of the rectangular piston rod 280 is connected to a rectangular plate 141, and a spring 142 is connected between the rectangular plate 141 and the installation box 100; a first air pipe 272 is connected between the rectangular cavity and the piston cylinder 270. After the pressure applied by the installation plate 110 to the rectangular plate 141 increases, the rectangular piston rod 280 can slide in the rectangular cavity, thereby transmitting to the round piston rod 271, so that the round piston rod 271 can pull out the rotating shaft 231.

[0043] When the mounting plate 110 rotates so that the pressure strips 150 are close to each other and squeeze the fingertips, the mounting plate 110 simultaneously applies pressure to the rectangular plate 141, and a spring 142 with appropriate elastic force is selected so that when the pressure overcomes the elastic force of the spring 142, the pressure of the pressure strip 150 on the fingertips can also reach an appropriate pressing force. Then the rectangular piston rod 280 slides to the rectangular cavity in the rectangular rod 140. At this time, the air in the rectangular cavity enters the piston cylinder 270 through the first air pipe 272, so that the round piston rod 271 pulls out the rotating shaft 231, and the rotating shaft 231 is unlocked.

[0044] A first wedge block 360 is slidably connected to the wall of the installation box 100, and a second wedge block 380 is fixedly connected to the side wall of the rotating shaft 231. The end of the first wedge block 360 is fixedly connected to the limiting plate 361 and a first tension spring 362 is connected between the limiting plate 361 and the outer wall of the installation box 100. When the rotating shaft 231 rotates one hundred and eighty degrees, the second wedge block 380 pushes the first wedge block 360 to slide, and then the second wedge block 380 is locked by the first wedge block 360.

[0045] After the round piston rod 271 is pulled out of the rotating shaft 231, the torsion of the torsion spring 261 is released, and the rotating shaft 231 rotates at this time, so that the second wedge block 380 on the rotating shaft 231 approaches the first wedge block 360. At this time, the second wedge block 380 pushes the first wedge block 360 to overcome the tension of the first tension spring 362 and slide, so that the rotating shaft 231 can rotate one hundred and eighty degrees. After the second wedge block 380 passes the position of the first wedge block 360, the first wedge block 360 resets and blocks the second wedge block 380, so that the rotating shaft 231 no longer reverses, avoiding the torsion of the torsion spring 261 from causing the rotating shaft 231 to rotate back and forth continuously.

[0046] A placement rack 300 is slidably connected to the installation box 100 , on which a detection card 301 is placed. The placement rack 300 can drive the detection card 301 to slide to the lower part of the fingertip.

[0047] After the needle 220 pricks the fingertip, the placement rack 300 slides toward the inside of the installation box 100 and is located under the fingertip. At this time, the blood dripping from the fingertip can be received by the test card 301, thereby achieving the effect of automatic sampling and testing;

[0048] A groove is provided on the placement rack 300 in the sliding direction thereof, and the detection card 301 is inserted into the groove, and the other end of the detection card 301 is inserted into the through slot provided on the wall of the installation box 100 .

[0049] A through hole is provided in the wall of the installation box 100, and the placement rack 300 includes a slide rod 310 that slides in the through hole. A cylindrical hole 370 is provided in the wall of the installation box 100, and a locking rod 350 is slidably connected in the cylindrical hole 370. A slot that cooperates with the locking rod 350 is provided on the side wall of the slide rod 310; a small cylinder 363 is connected between the limit plate 361 and the installation box 100, and a second air pipe 371 is connected between the small cylinder 363 and the cylindrical hole 370. When the second wedge block 380 pushes the first wedge block 360 to slide, the small cylinder 363 transmits to the locking rod 350, so that the locking rod 350 pulls out the slide rod 310.

[0050] When the first wedge 360 is pushed, the limit plate 361 pulls the small cylinder 363 to extend. At this time, the small cylinder 363 extracts air from the cylindrical hole 370 through the second air pipe 371, causing the locking rod 350 to slide down away from the slide bar 310. At this time, the slide bar 310 is unlocked, so that the placement rack 300 can slide into the installation box 100, allowing the detection card 301 to move to a position below the fingertip in the installation box 100.

[0051] The side wall of the slide bar 310 is also provided with an anti-stuck groove 311. The second wedge block 380 pushes the first wedge block 360 to slide, causing the small cylinder 363 to shorten and then extend. As a result, the small cylinder 363 drives the locking rod 350 away from the slide bar 310 and then moves closer to the slide bar 310. As the locking rod 350 approaches the slide bar 310 again, the end portion will fall into the anti-stuck groove 311 on the side wall of the slide bar 310. Then, the subsequent sliding of the slide bar 310 will not be hindered by the friction force of the locking rod 350. At the same time, it ensures that the locking rod 350 can extend to its original length, ensuring the smooth shortening of the small cylinder 363, thereby ensuring that the first wedge block 360 stably blocks the second wedge block 380.

[0052] The installation box 100 is fixedly connected to a U-shaped frame 320 , and the U-shaped frame 320 is fixedly connected to a magnetic block 340 via a second tension spring 330 . The magnetic block 340 slides in a through hole on the installation box 100 and is magnetically attracted to the slide rod 310 .

[0053] The end of the locking rod 350 has a rounded corner. When a push-pull force greater than that of the second tension spring 330 is applied to the placement rack 300, the sliding rod 310 can squeeze the locking rod 350 to shrink and slide into the cylindrical hole 370, thereby ensuring that the sliding rod 310 can be inserted into the through hole on the installation box 100. Alternatively, the limiting plate 361 can be manually pulled to extend the small cylinder 363 to drive the locking rod 350 to slide into the cylindrical hole 370 before the sliding rod 310 is inserted.

[0054] After the slide bar 310 is inserted into the through hole on the installation box 100, the placement rack 300 is pushed so that the end of the slide bar 310 contacts the magnetic block 340. Then, the placement rack 300 is pulled so that the slide bar 310 moves to the slot on the slide bar 310 opposite the locking rod 350. Then, the first wedge block 360 is pushed so that the locking rod 350 is pulled out of the slot on the slide bar 310. Then, the second tension spring 330 can pull the placement rack 300 to slide toward the inside of the installation box 100, so that the test card 301 is driven and moves to the position below the puncture point of the fingertip to receive blood.

[0055] During this process, the mounting plate 110 can be repeatedly pressed by the other hand, so that the pressure strip 150 repeatedly applies pressure to the fingertip, causing blood to drip out of the fingertip;

[0056] After the blood drips from the fingertip, loosen the mounting plate 110, remove the sampling finger, and then pull the placement rack 300 to separate it from the mounting box 100, so that the test card 301 can be taken out;

[0057] After use, the needle 220 is rotated to be removed, and a new needle 220 is rotated to be installed on the mounting rod 210, and the limit plate 361 is pulled to make the first wedge block 360 move away from the rotating shaft 231, and then the rotating shaft 231 is rotated to reset by the handle 232. When the rotating shaft 231 rotates until the slot on its side wall is opposite to the round piston rod 271, the round piston rod 271 is inserted into the slot on the rotating shaft 231, completing the locking of the rotating shaft 231, and then a new detection card 301 is installed on the placement rack 300, and then the placement rack 300 is installed on the installation box 100, and the device can be used again.

[0058] Working principle: When the automatic sampling gold standard penetration detection device is in use, the turntable 230 rotates back and forth under the action of the torsion spring 261. This reciprocating rotation is converted into axial reciprocating movement of the mounting rod 210 through the eccentric rod 240, thereby driving the needle 220 to prick the fingertips for sampling. During the rotation of the turntable 230, the interaction between the second wedge block 380 and the first wedge block 360 ensures that the rotating shaft 231 only rotates a specific angle, that is, one hundred and eighty degrees, to avoid excessive rotation causing the needle 220 to prick the fingertips multiple times. At the same time, the small cylinder 363 realizes precise control of the locking rod 350 through the connection design of the second air pipe 371 and the cylindrical hole 370, so that the placement rack 300 can slide to the inside of the mounting box 100 after the fingertips are pricked to receive the blood sample dripping from the fingertips.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
