Description

Technical Field

[0001] The present invention relates to the technical field of gold label penetration detection, and specifically provides a gold label penetration detection device with automatic sampling. Background Art

[0002] In the context of medical testing scenarios, fingertip blood sampling, as a common sampling method for blood glucose monitoring, initial disease screening, etc., its operational convenience is crucial for home health management and personal daily testing. Traditional fingertip blood sampling mostly relies on medical staff to manually complete, and there are many factors in the operation process that are not suitable for users to operate by themselves: on the one hand, it is difficult to accurately control the pressing force during blood sampling. Ordinary people lack professional training and are extremely likely to cause insufficient blood flow due to insufficient pressing or tissue damage due to excessive pressing; on the other hand, the manual operation process is complex, and each link from disinfection to needle insertion needs to be strictly regulated. When users operate by themselves, even a slight oversight may lead to risks such as infection, and it is difficult to ensure the accuracy and effectiveness of blood sampling.

[0003] With the popularization of home medical devices, although some automatic blood sampling devices have emerged, these devices still have obvious defects when used by users themselves. Some automatic blood sampling devices do not fully consider the operational convenience of self-sampling by users. They cannot effectively fix the finger before blood sampling, resulting in difficult control of the needle insertion angle and depth, which not only reduces the blood sampling success rate but also may cause accidental injuries; at the same time, there is a lack of a reasonable design for squeezing the finger pulp, making the pain intense when users self-sample blood, and it is difficult to collect a sufficient amount of blood samples, affecting the subsequent testing process. 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 of the existing detection card for users to self-collect blood for testing components.

[0005] To achieve the above object, the present invention provides the following technical solution: A gold label penetration detection device with automatic sampling, including an installation box. On both sides of the box opening of the installation box, two arc-shaped pressing blocks are symmetrically hinged. On both sides of the box opening of the installation box, two pressing strips are also symmetrically slidably connected. When the two arc-shaped pressing blocks approach each other, the two pressing strips simultaneously squeeze the finger pulp; A needle is linearly slidably connected to the middle of the installation box. The needle is facing the finger pulp. After the two pressing strips simultaneously squeeze the finger pulp, the needle reciprocates vertically for one stroke to pierce the finger pulp for sampling.

[0006] Preferably, mounting plates are symmetrically hinged on both sides of the opening of the mounting box. A rectangular rod is fixedly connected to the pressure strip. The rectangular rod penetrates and slides on the wall of the mounting box. Two arc-shaped pressing blocks are respectively connected to the two mounting plates. When the two mounting plates swing to make the two arc-shaped pressing blocks approach each other, the mounting plates synchronously drive the rectangular rod so that the two pressure strips approach each other.

[0007] Preferably, two turntables are rotatably connected in the mounting box. The two turntables are on the same axis, and an eccentric rod is connected between the two turntables; A sliding seat is fixedly connected in the mounting box. A mounting rod is slidably connected in the sliding seat. The needle head is threadedly connected to the mounting rod. The bottom end of the mounting rod is connected with a hollow strip. The eccentric rod slides in the hollow strip. When the two turntables rotate synchronously to make the eccentric rod slide in the hollow strip, the eccentric rod can drive the mounting rod to move axially back and forth.

[0008] Preferably, a rotating shaft is rotatably connected in the mounting box. The two turntables are coaxially connected to the rotating shaft. An installation ring is fixedly connected to the inner wall of the mounting box. The rotating shaft penetrates through the installation ring coaxially, and a torsion spring is connected between the rotating shaft and the installation ring. After the torsion spring stores and releases energy, it can drive the rotating shaft to rotate reciprocally.

[0009] Preferably, a piston cylinder is fixedly connected to the inner wall of the mounting box. A circular piston rod slides in the piston cylinder. A slot cooperating with the circular piston rod is formed on the side wall of the rotating shaft.

[0010] Preferably, a rectangular cavity is formed at the end of one of the rectangular rods. A rectangular piston rod slides in the rectangular cavity. The end of the rectangular piston rod is connected with a rectangular plate. A spring is connected between the rectangular plate and the mounting box; A first air pipe communicates between the rectangular cavity and the piston cylinder. After the pressure applied by the mounting plate on the rectangular plate increases, the rectangular piston rod can slide in the rectangular cavity, thereby driving the circular piston rod, so that the circular piston rod pulls out the rotating shaft.

[0011] Preferably, a first wedge block penetrates and slides on the wall of the mounting box. A second wedge block is fixedly connected to the side wall of the rotating shaft. A limiting plate is fixedly connected to the end of the first wedge block, and a first tension spring is connected between the limiting plate and the outer wall of the mounting box. When the rotating shaft rotates 180 degrees, the second wedge block pushes the first wedge block to slide, and then the second wedge block is locked by the first wedge block.

[0012] Preferably, a placement rack is slidably connected to the installation box, a detection card is placed on the placement rack, and the placement rack can drive the detection card to slide to the lower part of the finger pulp.

[0013] Preferably, through holes are formed in the box wall of the installation box. The placement rack includes a sliding rod that slides in the through holes. A cylindrical hole is formed in the box wall of the installation box, and a locking rod is slidably connected in the cylindrical hole. A slot that cooperates with the locking rod is formed in the side wall of the sliding rod; A small air cylinder is connected between the limiting plate and the installation box. A second air pipe is communicated between the small air cylinder and the cylindrical hole. When the second wedge block pushes the first wedge block to slide, the small air cylinder drives the locking rod, so that the locking rod pulls out the sliding rod.

[0014] Preferably, a U-shaped frame is fixedly connected to the installation box. A magnetic attraction block is fixedly connected to the U-shaped frame through a second tension spring. The magnetic attraction block slides in the through hole on the installation box and magnetically attracts the sliding rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, by placing the finger pulp between two arc-shaped pressing blocks, the finger pulp is located between two pressing strips. By controlling the two arc-shaped pressing blocks to approach each other, the two arc-shaped pressing blocks fix the nail part of the finger, and at the same time push the finger pulp to approach between the two pressing strips. At the same time, the two pressing strips approach each other to squeeze the finger pulp, reducing the pain during subsequent needle pricking of the finger pulp. Then, the needle moves towards the finger pulp and pricks the finger pulp to complete the sampling operation of fingertip blood. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1-8 , this embodiment provides a technical solution: an automatic sampling gold label penetration detection device, including a mounting box 100. On both sides of the box opening of the mounting box 100, two arc-shaped pressing blocks 120 are symmetrically hinged. On both sides of the box opening of the mounting box 100, two pressing strips 150 are also symmetrically slidably connected. When the two arc-shaped pressing blocks 120 approach each other, the two pressing strips 150 synchronously squeeze the finger pulp. In the middle of the mounting box 100, a needle head 220 is linearly slidably connected. The needle head 220 is facing the finger pulp. After the two pressing strips 150 synchronously squeeze the finger pulp, the needle head 220 reciprocates vertically for one stroke to pierce the finger pulp for sampling.

[0020] During use, after disinfecting the finger, place the finger pulp between the two arc-shaped pressing blocks 120 so that the finger pulp is between the two pressing strips 150. 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 at the same time push the finger pulp closer to the two pressing strips 150. At the same time, the two pressing strips 150 approach each other and squeeze both sides of the finger pulp, reducing the pain when pricking the finger pulp later. Then the needle head 220 moves towards the finger pulp and pierces the finger pulp to complete the sampling operation of fingertip blood. Therefore, this device can facilitate the user to collect blood by himself, making the blood collection process more convenient.

[0021] On both sides of the opening of the installation box 100, mounting plates 110 are symmetrically hinged. A rectangular rod 140 is fixedly connected to the pressure strip 150. The rectangular rod 140 penetrates and slides through the wall of the installation box 100. Two arc-shaped pressing blocks 120 are respectively connected to the two mounting plates 110. When the two mounting plates 110 swing to make the two arc-shaped pressing blocks 120 approach each other, the mounting plates 110 synchronously drive the rectangular rod 140 so that the two pressure strips 150 approach each other.

[0022] The installation box 100 is placed at the lower part so that the mounting plates 110 are at the upper part. After placing the fingers at the opening of the installation box 100, pinch the two mounting plates 110 to approach each other with the other hand. The mounting plates 110 drive the two arc-shaped pressing blocks 120 to approach each other. At the same time, the mounting plates 110 push the rectangular rod 140, so that the two pressure strips 150 approach the finger pulp at the same time.

[0023] A reinforcing frame 130 is also connected to the wall of the installation box 100. The rectangular rod 140 penetrates through the middle of the reinforcing frame 130. Two turntables 230 are rotatably connected in the installation box 100. The two turntables 230 are located on the same axis, and an eccentric rod 240 is connected between the two turntables 230; A sliding seat 200 is fixedly connected in the installation box 100. An installation rod 210 is slidably connected in the sliding seat 200. The needle head 220 is threadedly connected to the installation rod 210. A hollow strip 250 is connected to the bottom end of the installation rod 210. The eccentric rod 240 slides in the hollow strip 250. When the two turntables 230 rotate synchronously so that the eccentric rod 240 slides in the hollow strip 250, the installation rod 210 can be driven to move axially back and forth.

[0024] The installation rod 210 is perpendicular to the axis of the turntable 230, and the hollow strip 250 is horizontally arranged; After the finger pulp is pressed by the pressure strip 150, the turntable 230 rotates. At this time, the eccentric rod 240 slides in the hollow strip 250, and the installation rod 210 is limited by the sliding seat 200. Therefore, the rotation of the turntable 230 at this time can drive the installation rod 210 to slide axially back and forth. Furthermore, the installation rod 210 drives the needle head 220 to approach the finger pulp to prick the needle and then move away from the finger pulp.

[0025] A rotating shaft 231 is rotatably connected in the installation box 100. The two turntables 230 are coaxially connected to the rotating shaft 231. An installation ring 260 is fixedly connected to the inner wall of the installation box 100. The rotating shaft 231 penetrates through the installation ring 260 coaxially, and a torsion spring 261 is connected between the rotating shaft 231 and the installation ring 260. After the torsion spring 261 stores and releases energy, it can drive the rotating shaft 231 to rotate back and forth.

[0026] In the initial state, the rotation shaft 231 rotates to make the torsion spring 261 have torsion, and then the rotation shaft 231 is locked. Thus, when the rotation shaft 231 is unlocked, the torsion of the torsion spring 261 is released, enabling the rotation shaft 231 to rotate. Thereby, the rotation shaft 231 drives the turntable 230 to rotate, causing the needle 220 to pierce the finger pulp.

[0027] The inner wall of the installation box 100 is fixedly connected with a piston cylinder 270. A round piston rod 271 is slidably connected in the piston cylinder 270. A slot for cooperating with the round piston rod 271 is provided on the side wall of the rotation shaft 231.

[0028] The end of the round piston rod 271 is provided with a piston plate. After injecting air into the space in the piston cylinder 270 where this piston plate faces the round piston rod 271, the round piston rod 271 can be retracted into the piston cylinder 270. At this time, the round piston rod 271 is pulled out of the rotation shaft 231, thereby unlocking the rotation shaft 231. At this time, the torsion of the torsion spring 261 is released, thus driving the turntable 230 to rotate.

[0029] A rectangular cavity is provided at the end of one of the rectangular rods 140. A rectangular piston rod 280 is slidably connected in the rectangular cavity. The end of the rectangular piston rod 280 is connected with a rectangular plate 141. A spring 142 is connected between the rectangular plate 141 and the installation box 100. A first air pipe 272 is communicated between the rectangular cavity and the piston cylinder 270. After the pressure exerted by the installation plate 110 on the rectangular plate 141 increases, the rectangular piston rod 280 can slide in the rectangular cavity, thereby driving the round piston rod 271 to make the round piston rod 271 be pulled out of the rotation shaft 231.

[0030] When the installation plate 110 rotates to make the pressing strips 150 approach each other and squeeze the finger pulp, the installation plate 110 simultaneously exerts pressure on the rectangular plate 141. By selecting a spring 142 with appropriate elasticity, when the pressure overcomes the elasticity of the spring 142 and the pressure of the pressing strips 150 on the finger pulp can also reach an appropriate pressing force, then the rectangular piston rod 280 slides into 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, thereby pulling the round piston rod 271 out of the rotation shaft 231. At this time, the rotation shaft 231 is unlocked.

[0031] A first wedge block 360 is slidably connected through the box wall of the installation box 100. A second wedge block 380 is fixedly connected to the side wall of the rotation shaft 231. A limiting plate 361 is fixedly connected to the end of the first wedge block 360, and a first tension spring 362 is connected between the limiting plate 361 and the outer wall of the installation box 100. When the rotation shaft 231 rotates 180 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.

[0032] After the round piston rod 271 pulls out the rotating shaft 231, the torsion of the torsion spring 261 is released. At this time, the rotating shaft 231 rotates, 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 slide against the pulling force of the first tension spring 362, so that the rotating shaft 231 can rotate 180 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 rotates in reverse, avoiding the continuous reciprocating rotation of the rotating shaft 231 due to the torsion of the torsion spring 261.

[0033] A placement rack 300 is slidably connected to the installation box 100. A detection card 301 is placed on the placement rack 300, and the placement rack 300 can drive the detection card 301 to slide to the lower part of the finger pulp.

[0034] After the needle 220 pierces the fingertip, the placement rack 300 slides into the installation box 100 and is located below the finger pulp. At this time, the blood dripping from the finger pulp can be received by the detection card 301, so as to achieve the effect of automatic sampling and detection; A groove is formed in the placement rack 300 in the direction of its sliding. The detection card 301 is inserted into this groove, and the other end of the detection card 301 is inserted into a through groove formed in the wall of the installation box 100.

[0035] A through hole is formed in the wall of the installation box 100. The placement rack 300 includes a sliding rod 310 that slides in the through hole. A cylindrical hole 370 is formed in the wall of the installation box 100. A locking rod 350 is slidably connected in the cylindrical hole 370. A slot for cooperating with the locking rod 350 is formed on the side wall of the sliding rod 310; A small air cylinder 363 is connected between the limiting plate 361 and the installation box 100. A second air pipe 371 is communicated between the small air cylinder 363 and the cylindrical hole 370. When the second wedge block 380 pushes the first wedge block 360 to slide, the small air cylinder 363 drives the locking rod 350, so that the locking rod 350 pulls out the sliding rod 310.

[0036] When the first wedge block 360 is pushed, the limiting plate 361 pulls the small air cylinder 363 to extend. At this time, the small air cylinder 363 extracts the air in the cylindrical hole 370 through the second air pipe 371, so that the locking rod 350 slides down away from the sliding rod 310. At this time, the sliding rod 310 is unlocked, so that the placement rack 300 can slide into the installation box 100, so that the detection card 301 can move to a position below the finger pulp in the installation box 100; An anti-stuck groove 311 is also provided on the side wall of the slide bar 310. The second wedge block 380 pushes the first wedge block 360 to slide, causing the small cylinder 363 to shorten and then lengthen, so that the small cylinder 363 drives the locking rod 350 away from the slide bar 310 and then moves closer to the slide bar 310. When 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, and then the 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 the stable blocking of the second wedge block 380 by the first wedge block 360.

[0037] The installation box 100 is fixedly connected with a U-shaped frame 320 , and the U-shaped frame 320 is fixedly connected with 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 .

[0038] The end of the locking rod 350 has a rounded corner, and when the placement rack 300 applies a push-pull force greater than the second tension spring 330, 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. In addition, 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 inserting the sliding rod 310; 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, and then the placement rack 300 is pulled so that the slide bar 310 moves to the slot on the locking rod 350 facing the slide bar 310, so that the first wedge block 360 is pushed so that the locking rod 350 is pulled out of the slot on the slide bar 310, and the second tension spring 330 can pull the placement rack 300 to slide toward the inside of the installation box 100, so that the detection card 301 is driven and moved to the position below the puncture of the fingertip to receive blood; During this process, the mounting plate 110 can be repeatedly pressed by another hand, so that the pressure strip 150 repeatedly applies pressure to the finger pulp, causing blood to drip from the fingertip; After the blood drips out 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 detection card 301 can be taken out; After use, rotate and remove the needle 220, then rotate and install a new needle 220 on the mounting rod 210. Pull the limit plate 361 to move the first wedge 360 away from the rotating shaft 231, and then rotate the rotating shaft 231 back to its original position by turning the handle 232. When the slot on the side wall of the rotating shaft 231 is aligned with the round piston rod 271, the round piston rod 271 is inserted into the slot on the rotating shaft 231 to complete the locking of the rotating shaft 231. Then, install a new test card 301 on the placement rack 300, and install the placement rack 300 on the installation box 100, and the device can be used again.

[0039] Working principle: In this automatic sampling gold label penetration detection device, when in use, the turntable 230 makes a reciprocating rotation under the action of the torsion spring 261. This reciprocating rotation motion is converted into an axial reciprocating movement of the mounting rod 210 through the eccentric rod 240, thereby driving the needle 220 to puncture and sample the finger pulp. During the rotation of the turntable 230, the interaction between the second wedge 380 and the first wedge 360 ensures that the rotating shaft 231 only rotates a specific angle, that is, 180 degrees, avoiding multiple punctures of the finger pulp by the needle 220 caused by excessive rotation. At the same time, the design of the small air cylinder 363 communicating with the cylindrical hole 370 through the second air pipe 371 realizes the precise control of the locking rod 350, enabling the placement rack 300 to slide into the installation box 100 after the finger pulp is punctured to receive the blood sample dripping from the finger pulp.
