Description

Technical Field

[0001] The present invention relates to the technical field of heel blood collection devices, and particularly to an auxiliary device for neonatal heel blood collection. Background Art

[0002] Newborn heel blood screening is an important means to prevent neonatal genetic metabolic diseases and ensure the healthy growth of newborns. By collecting newborn heel blood, various diseases that seriously affect the intellectual and physical development of newborns, such as congenital hypothyroidism and phenylketonuria, can be detected early, so as to intervene and treat in time and reduce the harm of the diseases to newborns.

[0003] In the current practice of newborn heel blood collection, there are many problems to be solved in the traditional collection method. At present, most blood collection work relies on manual operation by medical staff, which requires extremely high professional skills and experience of medical staff. In the disinfection link, it is difficult to ensure the comprehensiveness and standardization of disinfection by manual operation. It is not easy to accurately control the wiping range and strength of the disinfection cotton ball, which may lead to incomplete disinfection and increase the risk of infection at the blood collection site.

[0004] The positioning of the blood collection position also mainly relies on the subjective judgment of medical staff, lacking accurate positioning means. Due to the small anatomical structure of the newborn heel and the inconvenience of observation, it is easy to have positioning deviation by relying on the naked eye and experience alone, which may lead to puncture failure or multiple punctures, not only bringing unnecessary pain to the newborn, but also affecting the quality of blood samples and the accuracy of subsequent test results.

[0005] During the puncture process, it is difficult to accurately control the strength and depth of manual puncture. Excessive strength may cause tissue damage to the heel, leading to complications such as excessive bleeding and hematoma; too little strength may result in unsuccessful puncture and the need for repeated punctures. In addition, inaccurate puncture depth may also affect the blood flow rate and collection volume, and cannot meet the strict requirements for blood volume in some test items.

[0006] In the blood collection stage, the existing collection method has low efficiency. When using ordinary blood collection filter paper for blood collection, it often takes multiple attempts to collect enough blood volume, and the blood is easily contaminated by external factors during the collection process, affecting the reliability of test results. Moreover, the entire blood collection process takes a long time, increasing the discomfort time of newborns and the work burden of medical staff.

[0007] Therefore, this device provides an auxiliary device for neonatal heel blood collection. Summary of the Invention

[0020] Firstly, it realizes the limit on both sides of the heel and the toes of the foot, effectively ensuring the normal operation of the subsequent blood collection operation. In the operation process of the neonatal heel intelligent blood collection device, the limit on both sides of the heel and the toes of the foot plays a key role. This design greatly improves the stability and accuracy of the blood collection operation. The auxiliary sleeve is a soft limit structure, while the limit device is a specific fixed limit mechanical structure. Through the cooperation of the two, it effectively prevents the heel from shaking or shifting left and right during blood collection, ensuring that the blood collection point determined by the positioning module always remains in a fixed position. During the puncture process, if the heel moves uncontrollably, it is very likely that the puncture needle will accidentally puncture other parts, causing accidental injuries. The limit devices on both sides of the heel are like a solid barrier, restricting the heel within a safe range and effectively avoiding such situations. This not only ensures the safety of newborns but also reduces the operation pressure of medical staff, enabling them to focus more on the blood collection operation and improving the overall medical safety.

[0021] Secondly, when the device performs blood collection on the neonatal heel, it can disinfect, puncture, and collect blood from the heel in an automated manner, saving a large amount of time and labor costs compared with traditional manual blood collection. It is especially suitable for large-scale neonatal disease screening and greatly improves the blood collection efficiency.

[0022] Thirdly, the device realizes the use of image recognition and pressure sensing technologies through the intelligent detection system, can position the blood collection position with an accuracy of up to millimeter level, and control the puncture depth error within a very small range, greatly reducing the puncture failure and repeated puncture caused by inaccurate positioning and ensuring the blood collection accuracy.

[0023] Fourthly, this device has achieved remarkable results in neonatal heel blood collection. In terms of accuracy, it uses image recognition and pressure sensing to accurately locate the blood collection position, precisely control the puncture depth, reduce failures and repeated punctures. In terms of safety, strict automated disinfection avoids cross-infection, the automatic control of the puncture needle reduces accidental injuries, and medical-grade filter paper ensures the reliability of samples. In terms of comfort, micro-needle puncture combined with precise operation reduces the pain of infants, and the rapid blood collection process shortens the uncomfortable time. In terms of efficiency, the fully automated operation greatly saves manpower and time, meets the needs of large-scale screening, and comprehensively improves the quality and efficiency of neonatal heel blood collection.

[0024] Fifthly, this device is widely used in the neonatal departments and obstetrics and gynecology departments of medical institutions at all levels, providing an efficient, accurate and safe blood collection solution for neonatal disease screening. At the same time, with the continuous optimization and improvement of technology, it can be further extended to other medical testing fields that require micro blood collection, with broad market prospects and application potential, and will bring new changes to the development of medical blood collection technology.

The position conversion shaft 46 is arranged at the through groove 331 and is rotatably connected to the height adjustment plate 33. The driven wheel 45 is sleeved on the position conversion shaft 46, and the belt 44 is sleeved on the driving wheel 43 and the driven wheel 45. The disinfection, puncture, and blood collection integrated device 5 includes a disinfection, puncture, and blood collection seat 51, a disinfection component 52, a puncture component 53, and a blood collection component 54. The disinfection, puncture, and blood collection seat 51 is arranged in the rotation groove 332 and its lower end is connected to the upper end of the position conversion shaft 46. The disinfection, puncture, and blood collection seat 51 is rotatably connected to the rotation groove 332. The lower part of the disinfection, puncture, and blood collection seat 51 is cylindrical and the upper part is square. The disinfection component 52, the puncture component 53, and the blood collection component 54 are respectively arranged on the upper part of the disinfection, puncture, and blood collection seat 51 and are equidistantly arranged on different square faces around the lower part of the disinfection, puncture, and blood collection seat 51. The disinfection component 52 includes an electric push rod 521, a push block 522, a disinfection head 523, a disinfection bottle 524, and a fixing frame 525. A placement groove 511 is provided on the disinfection, puncture, and blood collection seat 51. The electric push rod 521 is arranged in the placement groove 511. The push block 522 is arranged on the output end of the electric push rod 521. The fixing frame 525 is arranged at the side end of the disinfection, puncture, and blood collection seat 51.The disinfection bottle 524 is clamped on the fixing frame 525. The disinfection head 523 is connected to the disinfection bottle 524 in a communicating manner. The disinfection head 523 has the same structure as a traditional pressing and spraying product with the disinfection bottle 524. The disinfection bottle 524 and the disinfection head 523 are arranged in a J shape. The spraying port of the disinfection head 523 faces the leg placement seat 1;

[0050] When performing a heel blood sampling operation on a newborn, first, medical staff place the heel of the newborn to be sampled on the leg placement seat, and use the auxiliary sleeve 6 to cover the toes of the foot to achieve a constraining effect. Then, the second limiting fixture 71 operates to drive the two limiting clamping blocks 72 to move symmetrically inward to clamp and limit the two sides of the newborn's heel. This process realizes the limitation of the two sides of the heel and the toes of the foot, effectively ensuring the normal operation of the subsequent blood sampling operation. In the operation process of the intelligent newborn heel blood sampling device, the limitation of the two sides of the heel and the toes of the foot plays a key role. This design greatly improves the stability and accuracy of the blood sampling operation. The auxiliary sleeve 6 is a soft limiting structure, while the limiting device 7 is a specific fixed limiting mechanical structure. Through the cooperation of the two, it effectively prevents the heel from shaking or shifting left and right during the blood sampling process, ensuring that the blood sampling point determined by the positioning module always remains in a fixed position. During the puncture process, if the heel moves uncontrollably, it is very likely that the puncture needle will accidentally puncture other parts, causing accidental injuries. The limiting device 7 on both sides of the heel is like a solid barrier, restricting the heel within a safe range and effectively avoiding the occurrence of such situations. This not only ensures the safety of the newborn but also reduces the operation pressure on medical staff, enabling them to focus more on the blood sampling operation and improving the overall medical safety.

[0051] After the two sides of the neonatal heel and the toes are limited, first, the intelligent detection system 8 uses the cooperation of image recognition, optical sensors and height sensors to achieve accurate real-time positioning and movement of the device. The operation of two multi-section telescopic electric cylinders 22 drives the corresponding height adjustment blocks 31 on the output ends of the two multi-section telescopic electric cylinders 22 to perform translational motion, thereby driving the disinfection component 52 on the height adjustment plate 33 to translate, so that the disinfection component 52 and the neonatal heel maintain a distance at which the heel blood collection position can be sprayed with disinfectant. Then, the operation of two screw rod slides 32 drives the height adjustment plate 33 to adjust the height, so as to adjust the height of the disinfection component 52 on the height adjustment plate 33, so that the spraying end of the disinfection component 52 is exactly facing the required neonatal heel for blood collection position. Then, the operation of the electric push rod 521 drives the push block 522 on the electric push rod 521 to move. By the movement of the push block 522, the disinfection head 523 is symmetrically pressed. Through the repeated telescopic movement of the electric push rod 521, the disinfectant liquid inside the disinfection bottle 524 is sprayed out by repeatedly pressing the disinfection head 523 through the push block 522, and it is exactly sprayed on the neonatal heel blood collection position required. In this way, it realizes the accurate movement of the disinfection component 52 towards the neonatal heel puncture position automatically, and makes the disinfection component 52 aim at the heel puncture part for disinfection operation;

[0052] The disinfection process of neonatal heel blood collection achieves a precise and automated disinfection effect:

[0053] Precise positioning and movement: With the help of the intelligent detection system 8, comprehensively using image recognition, optical sensors and height sensors, the device can accurately locate the position of the neonatal heel in real time and achieve its own accurate movement accordingly. The two multi-section telescopic electric cylinders 22 drive the height adjustment blocks 31 to translate, and then the disinfection component 52 on the height adjustment plate 33 is translated to maintain an appropriate horizontal distance from the neonatal heel blood collection position, ensuring that the disinfection component 52 can accurately aim at the target area and providing a position basis for subsequent disinfection operations.

[0054] High-precision height adjustment: The two screw rod slides 32 are used to adjust the height of the height adjustment plate 33, so that the spraying end of the disinfection component 52 can accurately face the neonatal heel blood collection position. This precise height adjustment function ensures that the disinfectant liquid can be sprayed onto the target area at the best angle, improves the disinfection effect, and avoids waste of disinfectant liquid and contamination of unnecessary surrounding areas.

[0055] Automated and efficient disinfection: The operation of the electric push rod 521 drives the pushing block 522 to symmetrically press the disinfection head 523. Through the repeated telescoping of the electric push rod 521, the repeated pressing of the disinfection head 523 is realized, so that the disinfectant in the disinfection bottle 524 is stably and continuously sprayed onto the neonatal heel blood collection site. The whole process has a high degree of automation, accurate and efficient operation, ensuring that the blood collection site can be fully and evenly disinfected, creating a sterile and safe environment for the subsequent blood collection operation and effectively reducing the infection risk.

[0056] Preferably, the puncture assembly 53 includes a limiting clamp 531 and a blood collection puncture needle 532. A clamping groove 512 is provided on the disinfection puncture blood collection seat 51. The limiting clamp 531 is located in the clamping groove 512, and the blood collection puncture needle 532 is arranged in the clamping groove 512 and is clamped and fixed by the limiting clamp 531;

[0057] Before disinfecting and puncturing the newborn, the blood collection filter paper 543 needs to be clamped by the first position-limiting fixture 542 and clamped in an inclined state. This is more conducive to the blood collection filter paper 543 coming into contact with the position after heel puncture to collect blood. After disinfection, heel puncture blood collection operation needs to be carried out on the newborn's heel. First, the position conversion motor 42 runs to drive the rotation of the driving wheel 43 on the output end of the position conversion motor 42. The rotation of the driving wheel 43 drives the rotation of the driven wheel through the transmission of the belt 44, thereby driving the rotation on the height adjustment plate 33 on the position conversion shaft 46. After the position conversion shaft 46 rotates to drive the disinfection puncture blood collection seat 51 to rotate counterclockwise by 90 degrees, at this time, the position conversion motor 42 stops running. At this time, the puncture assembly 53 is facing the direction of the newborn's heel. Then, through the cooperation of image recognition, optical sensors and height sensors of the intelligent detection system 8, the accurate real-time positioning and movement of the device are realized. Through the synchronous operation of the two multi-joint telescopic electric cylinders 22 and the two lead screw sliders 32, the height and position of the disinfection puncture blood collection seat 51 on the height adjustment plate 33 are changed, thereby driving the height and position changes of the puncture assembly 53 on the disinfection puncture blood collection seat 51, so as to accurately align the blood collection puncture needle 532 with the puncture collection position of the newborn's heel. Finally, the two multi-joint telescopic electric cylinders 22 run again to move the puncture assembly 53 horizontally towards the direction of the newborn's heel. Finally, the blood collection puncture needle 532 is used to puncture the newborn's heel. After the puncture is completed, the two multi-joint telescopic electric cylinders 22 run immediately to drive the puncture assembly 53 to disengage from the heel and be at a safe distance. Then, the position conversion motor 42 runs to drive the disinfection puncture blood collection seat 51 to rotate counterclockwise by 90 degrees again, so that the blood collection assembly 54 is facing the heel position at this time. And through the cooperation of image recognition, optical sensors and height sensors of the intelligent detection system 8, the accurate real-time positioning and movement of the device are realized, and finally the collection point on the blood collection filter paper 543 is brought into contact with the heel puncture site to achieve blood collection. During the blood collection process, the blood collection filter paper 543 can be repeatedly detached and brought into contact with the heel puncture part, and the blood collection filter paper 543 can collect blood multiple times. And during the blood collection process, only one or two drops of blood may flow out from the punctured heel. For this uncertain factor, during the collection process, the second position-limiting fixture 71 can be run to drive the two position-limiting clamping blocks 72 to move symmetrically inward to clamp and squeeze both sides of the newborn's heel, so as to achieve the effect of squeezing the blood of the newborn's heel, which is convenient for the blood collection filter paper 543 to collect blood multiple times, thus realizing the puncture of the newborn's heel and the completion of the blood collection operation in an automated manner. The blood collection assembly 54 includes a first lead screw slider 541, a first position-limiting fixture 542 and a blood collection filter paper 543. The first lead screw slider 541 is arranged at the side end of the disinfection puncture blood collection seat 51. The first position-limiting fixture 542 is inclined and arranged on the moving end of the first lead screw slider 541.The lead screw slide table 541 is horizontally arranged, and the blood collection filter paper 543 is clamped and limited by the first limiting fixture 542;

[0058] In the neonatal heel blood collection process, each device collaboratively achieves an efficient, precise, and flexible blood collection effect:

[0059] Pre-clamping and positioning optimization of the blood collection filter paper 543: The blood collection filter paper 543 is clamped in an inclined state by the first limiting fixture 542 to pre-optimize its contact position with the heel puncture site, creating convenient conditions for blood collection and ensuring that blood can be collected more smoothly after puncture;

[0060] Precise positioning and execution of the puncture operation: Using mechanical structures such as the position conversion motor 42, the driving wheel 43, the belt 44, the transmission wheel, and the position conversion shaft 46, the angle of the disinfected puncture blood collection seat 51 is precisely adjusted. In cooperation with the intelligent detection system 8 (image recognition, optical sensor, and height sensor), as well as two multi-section telescopic electric cylinders 22 and two lead screw slide tables 32, the height and position of the puncture assembly 53 are precisely adjusted, so that the puncture needle is accurately aligned with the neonatal heel puncture collection position, the puncture operation is completed, and after puncture, the puncture assembly 53 is quickly separated from the heel to a safe distance to ensure the safety of the neonate;

[0061] Intelligent and flexible operation of blood collection: Once again, the angle of the disinfected puncture blood collection seat 51 is adjusted by the position conversion motor 42 to make the blood collection assembly 54 face the heel. Relying on the precise positioning of the intelligent detection system 8, the collection point of the blood collection filter paper 543 is brought into contact with the heel puncture site to achieve blood collection. In view of the uncertain blood outflow volume, the second limiting fixture 71 is operated to drive the limiting clamping block 72 to squeeze both sides of the heel to promote blood outflow. At the same time, the blood collection filter paper 543 can be repeatedly brought into contact with the heel puncture site to achieve multiple blood collections, improving the blood collection success rate and sample quality;

[0062] The main purposes of collecting blood multiple times through the blood collection filter paper 543 are as follows:

[0063] Ensure sufficient blood volume collection: The blood volume in the neonatal heel is limited, and the blood outflow volume after each puncture is uncertain. It may only flow out one or two drops. Multiple collections can accumulate enough blood samples to meet the blood volume requirements for various tests and avoid the inability to perform tests or inaccurate results due to insufficient blood volume;

[0064] Improve the detection accuracy: Multiple collections can obtain more representative blood samples. The blood collected at different times may contain substances with different components or concentrations. The sample obtained by mixing multiple collections can more comprehensively reflect the blood condition of the neonate, reduce the detection error caused by sample deviation, and improve the accuracy and reliability of the detection results;

[0065] Handling special situations: For some test items, repeated or backup tests may be required. The blood collected multiple times can provide sufficient samples for subsequent possible rechecks or other related tests to handle situations where the initial test results are abnormal or further confirmation is needed.

[0066] Preferably, the auxiliary sleeve 6 includes an elastic band 61 and a wrapping limiting sleeve 62. There are two elastic bands 61, and the two elastic bands 61 are symmetrically arranged on the leg placement seat 1. The wrapping limiting sleeve 62 is arranged on the two elastic bands 61. The wrapping limiting sleeve 62 is adapted to the size of the newborn's foot and has elastic stretching toughness. Both of the two elastic bands 61 have elastic stretching toughness. The limiting device 7 includes a second limiting clamp 71 and a limiting clamping block 72. There is a fixing groove 12 on the leg placement seat 1. The second limiting clamp 71 is arranged in the fixing groove 12. There are two limiting clamping blocks 72, and the two limiting clamping blocks 72 are symmetrically arranged on the two clamping ends of the limiting clamp 531. Soft layers are provided on the inner surfaces of the two limiting clamping blocks 72.

[0067] In this device, the second limiting clamp 71, the first limiting clamp 542, and the limiting clamp 531 have the same structure and adopt the same structure as traditional mechanical jaws to achieve clamping and limiting. The intelligent detection system 8 includes an operating system, a graphic recognition system, a pressure sensor, a height sensor, and an optical sensor. The operating system is arranged at the side end of the leg placement seat 1. There are two pressure sensors, and the two pressure sensors are respectively arranged on the corresponding upper limiting clamping blocks 72. The graphic recognition system, the height sensor, and the optical sensor are respectively arranged on the height adjustment plate 33 and are all arranged towards the leg placement seat 1. The graphic recognition system, the two pressure sensors, the height sensor, and the optical sensor are all wirelessly connected to the operating system.

[0068] After completing the neonatal intelligent puncture blood collection operation, detach from the neonatal heel through each device and maintain a safe distance. Loosen both sides of the heel through the limiting device 7, and synchronously move it out of the leg placement seat 1. When performing the next neonatal blood collection, it is necessary to operate the position conversion motor 42 to drive the disinfection puncture blood collection seat 51 to rotate clockwise by 180 degrees, so as to drive the disinfection component 52 on the disinfection puncture blood collection seat 51 to return to the direction facing the leg placement seat 1 again. Then, remove and hold the collected blood collection filter paper 543, replace it with a new blood collection filter paper 543, and remove and replace the puncture needle with a new one. Then, through the synchronous operation of the two multi-joint telescopic electric cylinders 22 and the two screw rod sliders 32, the height and position of the disinfection puncture blood collection seat 51 on the height adjustment plate 33 can be changed, so as to drive the height and position of the disinfection component 52 on the disinfection puncture blood collection seat 51 to change, and drive the disinfection component 52 to translate from the head end of the leg placement seat 1 to the tail end of the leg placement seat 1. During the translation process, operate the electric push rod 521 to drive the push block 522 on the electric push rod 521 to move. Through the movement of the push block 522, symmetrically press the disinfection head 523. Through the repeated telescopic movement of the electric push rod 521, the disinfectant liquid inside the disinfection bottle 524 is sprayed out by repeatedly pressing the disinfection head 523 through the push block 522, thereby realizing the spraying and disinfection operation on the inner side of the leg placement seat 1, effectively preventing the occurrence of cross-infection, ensuring the hygiene and safety of the blood collection environment, providing good conditions for subsequent neonatal blood collection, and thus making preparations for equipment and consumables for the next blood collection, ensuring the accuracy and safety of subsequent blood collection.

[0069] Workflow of this device

[0070] Preparation stage: Medical staff place the neonatal heel at the designated position of the device and start the device. The device automatically performs full-range image acquisition and pressure detection on the heel, and completes the positioning of the disinfection area and the blood collection position.

[0071] Disinfection stage: The disinfection module performs disinfection operations according to the preset program. During spray disinfection, alcohol evenly covers the heel blood collection area in a fine mist; during wiping disinfection, it is gently wiped with a disinfection cotton to ensure thorough disinfection. After disinfection, the air-drying device quickly dries the residual alcohol.

[0072] Puncture stage: After the positioning is completed and the disinfection area is dry, the puncture module is started. The puncture needle quickly penetrates the heel at a precise angle and depth, and immediately retracts the needle after puncture. The whole process is completed in a very short time, reducing the pain time of the baby.

[0073] Blood collection stage: The blood collection filter paper 543 automatically adheres to the puncture site and starts collecting blood. The device monitors the blood collection progress in real time. When the amount of blood absorbed by the filter paper reaches the standard, it automatically stops blood collection and prompts the medical staff to take out the filter paper and perform sample labeling and preservation.

[0074] Accuracy: Image recognition and pressure sensing technologies ensure that the positioning accuracy of the blood collection location reaches the millimeter level, and the puncture depth error is controlled within a very small range, greatly improving the accuracy of blood collection and reducing blood collection failures and repeated punctures caused by improper operations.

[0075] Safety: The disinfection process strictly follows medical standards to avoid the risk of cross-infection; the puncture needle is automatically controlled to reduce human operation errors and the possibility of accidental injuries; the blood collection filter paper 543 meets medical-grade standards to ensure the preservation and detection accuracy of blood samples.

[0076] Comfort: Microneedle puncture technology and precise puncture control significantly reduce the puncture pain of newborns; the automated operation process reduces the blood collection time and the discomfort of infants.

[0077] Efficiency: The full-process automated operation greatly improves the blood collection efficiency. Compared with the traditional manual blood collection method, it can save a large amount of time and labor costs, especially suitable for large-scale neonatal disease screening scenarios.
