Description

Technical Field

[0001] This invention relates to the field of neonatal plantar blood collection technology, specifically to a neonatal plantar blood collection device for neonatal care. Background Technology

[0002] Newborn heel prick blood sampling, also known as neonatal genetic metabolic disease screening, is an important health check for newborns. A few drops of blood are collected from the baby's heel 72 hours after birth, after adequate breastfeeding. It is used to screen for genetic metabolic disorders such as congenital hypothyroidism, phenylketonuria, and G6PD deficiency. These diseases often present without outward signs in their early stages, but once they develop, they can cause irreversible damage to intelligence and physical health. Early screening and intervention can ensure normal growth and development for the baby. If the initial screening is abnormal, a follow-up test is necessary. A follow-up test does not guarantee a diagnosis, and parents should not be overly anxious. Premature babies or babies discharged early should have a follow-up blood sample taken as prescribed by their doctor.

[0003] Current procedures for neonatal foot blood sampling typically involve first disinfecting the sole of the foot, then puncturing the skin with a lancet. Medical staff manually squeeze the skin from the distal end of the limb towards the puncture point, discarding the first drop of blood before collecting subsequent samples. This method is suitable for newborns with normal skin. However, for newborns with foot skin lesions, such as pustules or bullae, traditional blood sampling methods are no longer applicable. Firstly, the skin barrier of these infants is fragile, and squeezing can easily induce blisters, epidermal tearing, and even rupture of pustules, worsening skin damage. Secondly, secretions from the lesion site pose a risk of pathogen exposure, potentially causing occupational infections for medical staff. Therefore, this paper proposes a new foot blood sampling device for neonatal care to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a foot blood collection device for newborn care, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an optional embodiment of the newborn care foot blood collection device described in this invention, the newborn care foot blood collection device includes a protective soft pad, a foot support ring, and a newborn foot adjustment module. A foot support ring is fixedly connected to one side of the protective pad, and a first fixing sleeve for fitting and fixing the newborn's foot is installed on one side of the foot support ring. A second fixing sleeve is also installed above the protective pad; A newborn foot adjustment module is also installed on one side of the protective pad. A diversion component is connected above the newborn foot adjustment module. The other end of the diversion component is connected to the newborn foot compression module inside the foot support ring. The two sides of the newborn foot compression module are slidably connected to the inner wall of the foot support ring. One end of the newborn foot adjustment module also passes through one side of the foot support ring and extends to the inner side of the foot support ring. An arc-shaped groove is provided on the inner bottom of the foot support ring, and the foot support ring is slidably connected to the foot plate squeezing module through the arc-shaped groove. One end of the foot plate squeezing module is connected to the diverter.

[0006] The diversion component includes a diversion tube, a hollow disc, and branch tubes. The bottom of the diversion tube is connected to the newborn foot adjustment module, and the other end of the diversion tube is connected to the hollow disc. The other end of the hollow disc is connected to multiple branch tubes, and the other ends of the multiple branch tubes pass through the inside of the foot support ring and are connected to multiple newborn foot compression modules. One end of one of the branch pipes is connected to the foot plate extrusion module.

[0007] As an optional embodiment of the foot blood collection device for neonatal care described in this invention, the foot plate compression module includes a hollow cover, a sliding plate, and a second compression airbag. The sliding plate is fixedly connected to the outer side of the hollow cover, and the outer side of the sliding plate is slidably connected to the foot support ring through an arc-shaped groove opened at the bottom of the foot support ring. The hollow cover also has a second compression airbag installed inside. The side of the second compression airbag is connected to the diversion component, and a second flexible pressure sensor is also installed on one side of the second compression airbag.

[0008] The current procedure for neonatal foot puncture blood collection typically involves first disinfecting the sole of the foot, then puncturing the skin with a lancet. Medical staff manually squeeze the skin from the distal end of the limb towards the puncture point, discarding the first drop of blood before collecting subsequent samples. This method is suitable for newborns with normal skin. However, for newborns with foot skin lesions, such as pustules or bullae, the traditional blood collection method is no longer applicable. On the one hand, the skin barrier of such infants is fragile, and squeezing operations can easily induce blisters, epidermal tearing, and even rupture of pustules, aggravating skin damage. On the other hand, secretions from the lesion site pose a risk of pathogen exposure, easily causing occupational infection for medical staff. By installing this device on the newborn's foot, the first and second fixing sleeves are used to fix the foot, allowing the foot support ring to fit properly on the foot of the newborn with foot skin disease. According to the actual condition of the infant's foot, multiple newborn foot squeezing modules are arranged in corresponding positions on the newborn's foot. After disinfection and puncture of the corresponding area of ​​the newborn's heel, the newborn foot adjustment module is activated, sequentially driving each newborn foot squeezing module. In conjunction with the foot sole squeezing module, each module adopts a step-by-step sequential activation mode, realizing progressive squeezing from the distal end of the limb towards the puncture point. Compared with the traditional manual squeezing method, this device transmits force vertically to the foot, avoiding force tilting and deviation, effectively preventing the rupture of lesions such as abscesses on the newborn's foot by external force, ensuring the safety of the newborn's foot.

[0009] As an optional embodiment of the neonatal foot blood collection device described in this invention, the neonatal foot compression module includes an adjustment plate, a rotating handle, and a threaded shaft. One side of the adjustment plate is connected to a diverter, and both ends of the adjustment plate are fixedly connected to sliding plates. The outer side of the sliding plates is slidably connected to the inner wall groove of the foot support ring. Multiple sets of pressing adjustment components are installed inside the adjustment plate, and a third electromagnetic valve for closing or opening the airway of the branch tube is also installed on the side of the adjustment plate near the branch tube. The sliding plate on one side is internally connected with a locking bolt, which is located in the groove on one side of the foot support ring. The pressing adjustment component includes a rotating handle, a threaded shaft, and a movable frame. The threaded shaft is fixedly connected to one side of the rotating handle, and the movable frame is rotatably connected to the other end of the threaded shaft. The first compression air bladder is fixedly connected inside the movable frame, and the side of the first compression air bladder is connected to a diverter.

[0010] As an optional embodiment of the newborn care foot blood collection device of the present invention, wherein: a first flexible pressure sensor is installed on one side of the first compression airbag, and the outer side of the moving frame is slidably connected to the adjustment plate.

[0011] During the process of collecting blood from the sole of a newborn's foot, if there is an abscess lesion on the sole, the handle can be turned to rotate the threaded shaft and lock it in place with the thread of the adjusting plate, thus restricting the movement of the moving frame. This avoids the first compression airbag inside the moving frame from exerting pressure on the abscess area on the sole of the foot, achieving selective avoidance of the compression area and further ensuring the safety of the newborn's foot.

[0012] As an optional embodiment of the newborn foot blood collection device described in this invention, the newborn foot adjustment module includes a side frame, an air pump device, and an exhaust pipe. The side of the side frame is fixedly connected to the protective pad. A partition is installed inside the side frame. An air pump device is fixedly connected to the side frame on one side of the partition. The output end of the air pump device is connected to the exhaust pipe. The other end of the exhaust pipe is connected to a diverter. A first solenoid valve is also installed on the outside of the exhaust pipe. A hot air delivery pipe is connected to the top of the side frame. The hot air delivery pipe is equipped with multiple exhaust ends, which are distributed on one side of the inner wall of the foot support ring.

[0013] As an optional embodiment of the newborn care foot blood collection device of the present invention, wherein: a shunt pipe is connected to one side of the exhaust pipe, and two exhaust ports are led out from one side of the shunt pipe. The two exhaust ports pass through the partition and are located on the upper and lower sides of the semiconductor heating and cooling component inside the side frame. A second solenoid valve is also installed on the outside of the shunt pipe.

[0014] As an optional embodiment of the newborn care foot blood collection device of the present invention, wherein: a deformable hose is also connected to the side of the side frame, and one end of the deformable hose is connected to a hollow cover.

[0015] Before the blood collection operation begins, the temperature is controlled by the semiconductor heating and cooling components inside the side frame. The hot air generated by the heating side of the semiconductor heating and cooling components is delivered to the newborn's foot area through the hot air delivery pipe. The warmth improves the blood circulation in the newborn's feet, creating favorable conditions for blood collection. At the same time, the cold air generated by the cooling side of the semiconductor heating and cooling components is delivered to the cover through the deformable hose to apply a cold compress to the puncture area and reduce the stinging sensation caused by the puncture.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This device is installed on the newborn's foot, and the first and second fixing sleeves are used to position and fix the foot, allowing the foot support ring to fit properly on the foot of a newborn with foot skin disease. Based on the actual condition of the infant's foot, multiple newborn foot compression modules are placed at corresponding positions on the newborn's foot. After disinfection and puncture of the corresponding area on the newborn's heel, the newborn foot adjustment module is activated, sequentially driving each newborn foot compression module. Each module operates in a step-by-step sequential activation mode, achieving progressive compression from the distal end of the limb towards the puncture point. Compared to traditional manual pushing methods, this device transmits force vertically to the foot, avoiding force tilting or deviation, effectively preventing the rupture of abscesses and other lesions on the newborn's foot due to external force, ensuring the safety of the newborn's foot.

[0017] During the process of collecting blood from the sole of a newborn's foot, if there is an abscess lesion on the sole, the handle can be turned to rotate the threaded shaft and lock it in place with the thread of the adjusting plate, thus restricting the movement of the moving frame. This avoids the first compression airbag inside the moving frame from exerting pressure on the abscess area on the sole of the foot, achieving selective avoidance of the compression area and further ensuring the safety of the newborn's foot.

[0018] Before the blood collection operation begins, the temperature is controlled by the semiconductor heating and cooling components inside the side frame. The hot air generated by the heating side of the semiconductor heating and cooling components is delivered to the newborn's foot area through the hot air delivery pipe. The warmth improves the blood circulation in the newborn's feet, creating favorable conditions for blood collection. At the same time, the cold air generated by the cooling side of the semiconductor heating and cooling components is delivered to the cover through the deformable hose to apply a cold compress to the puncture area and reduce the stinging sensation caused by the puncture.

Detailed Implementation

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 6 The present invention provides a technical solution: A newborn foot blood collection device includes a protective pad 1, a foot support ring 2, and a newborn foot adjustment module 3; A foot support ring 2 is fixedly connected to one side of the protective soft pad 1, and a first fixing sleeve 6 for fitting and fixing the newborn's foot is installed on one side of the foot support ring 2. A second fixing sleeve 8 is also installed above the protective pad 1; A newborn foot adjustment module 3 is also installed on one side of the protective pad 1. A diversion component 4 is connected above the newborn foot adjustment module 3. The other end of the diversion component 4 is connected to the newborn foot compression module 5 inside the foot support ring 2. The two sides of the newborn foot compression module 5 are slidably connected to the inner wall of the foot support ring 2. One end of the newborn foot adjustment module 3 also passes through one side of the foot support ring 2 and extends to the inner side of the foot support ring 2. An arc-shaped groove is provided on the inner bottom of the foot support ring 2, and the foot support ring 2 is slidably connected to the foot plate squeezing module 7 through the arc-shaped groove. One end of the foot plate squeezing module 7 is connected to the diverter 4.

[0022] The diversion component 4 includes a diversion pipe 401, a hollow disc 402, and branch pipes 403. The bottom of the diversion pipe 401 is connected to the newborn foot adjustment module 3. The other end of the diversion pipe 401 is connected to the hollow disc 402. The other end of the hollow disc 402 is connected to multiple branch pipes 403. The other ends of the multiple branch pipes 403 pass through the inside of the foot support ring 2 and are connected to multiple newborn foot compression modules 5. One end of one of the branch pipes 403 is connected to the foot plate extrusion module 7.

[0023] The foot plate compression module 7 includes a hollow cover 701, a sliding plate 702, and a second compression airbag 703. The outer side of the hollow cover 701 is fixedly connected to the sliding plate 702, and the outer side of the sliding plate 702 is slidably connected to the foot support ring 2 through an arc-shaped groove opened at the bottom of the foot support ring 2. The hollow cover 701 also has a second compression airbag 703 installed inside. The side of the second compression airbag 703 is connected to the diverter 4. A second flexible pressure sensor 704 is also installed on one side of the second compression airbag 703.

[0024] The current procedure for neonatal foot puncture blood collection typically involves first disinfecting the sole of the foot, then puncturing the skin with a lancet. Medical staff manually squeeze the skin from the distal end of the limb towards the puncture point, discarding the first drop of blood before collecting subsequent samples. This method is suitable for newborns with normal skin. However, for newborns with foot skin lesions, such as pustules or bullae, the traditional blood collection method is no longer applicable. On the one hand, the skin barrier of such infants is fragile, and squeezing operations can easily induce blisters, epidermal tearing, and even rupture of pustules, aggravating skin damage. On the other hand, the secretions from the lesion site pose a risk of pathogen exposure, which can easily cause occupational infection for medical staff. By installing this device on the newborn's foot, the first fixing sleeve 6 and the second fixing sleeve 8 are used to fix the foot, allowing the foot support ring 2 to be fitted to the foot of the newborn with foot skin disease. According to the actual foot condition of the infant, multiple newborn foot squeezing modules 5 are arranged in the corresponding positions on the newborn's foot. After disinfection and puncture of the corresponding area of ​​the newborn's heel, the newborn foot adjustment module 3 is activated, driving each newborn foot squeezing module 5 in sequence. In conjunction with the foot sole squeezing module 7, each module adopts a step-by-step sequential activation mode to achieve progressive squeezing from the distal end of the limb towards the puncture point. Compared with the traditional manual squeezing method, the force of this device is transmitted vertically to the foot, which can avoid the force tilting and deviation, effectively preventing the rupture of lesions such as abscesses on the newborn's foot by external force, and ensuring the safety of the newborn's foot.

[0025] Also includes the following: The neonatal foot compression module 5 is adjusted according to the condition of the newborn's foot. It is activated by the neonatal foot adjustment module 3, which allows air to enter the hollow plate 402 through the diversion tube 401. Then, it is collected through the branch tube 403 into the inside of the pressing adjustment component of the neonatal foot compression module 5 and the inside of the foot sole compression module 7. The pressing adjustment component gradually squeezes from the distal end of the limb towards the puncture point to help blood flow out and facilitate subsequent blood collection operations. When gas enters the second compression airbag 703, the second compression airbag 703 expands and squeezes the newborn's foot. In conjunction with the newborn foot compression module 5, it helps blood flow to the puncture area, facilitating subsequent blood collection. Furthermore, a second flexible pressure sensor 704 is also provided on one side of the second compression airbag 703 to detect the pressure in contact with the newborn's foot. If the pressure exceeds the set threshold, it will be depressurized in time. Meanwhile, the sliding disc 702 on the side of the hollow cover 701 allows for easy adjustment of the hollow cover 701. When puncturing the heel of a newborn, the hollow cover 701 can slide to the opposite side to squeeze the other side, ensuring that blood flows out smoothly for subsequent collection.

[0026] Example 2: This example is an improvement on Example 1. Please refer to Example 1. Figure 4 and Figure 5 Specifically, the newborn foot compression module 5 includes an adjustment plate 501, a rotating handle 502, and a threaded shaft 503. One side of the adjustment plate 501 is connected to the diverter 4, and both ends of the adjustment plate 501 are fixedly connected to sliding plates 507. The outer side of the sliding plate 507 is slidably connected to the inner wall groove of the foot support ring 2. Multiple sets of pressing adjustment components are installed inside the adjustment plate 501, and a third solenoid valve 509 for closing or opening the airway of the branch pipe 403 is also installed on the side of the adjustment plate 501 near the branch pipe 403. A locking bolt 508 is spirally connected inside the sliding plate 507 on one side. The locking bolt 508 is located in the strip groove opened on one side of the foot support ring 2. The pressing adjustment component includes a rotating handle 502, a threaded shaft 503, and a movable frame 504. The threaded shaft 503 is fixedly connected to one side of the rotating handle 502, and the movable frame 504 is rotatably connected to the other end of the threaded shaft 503. The first compression air bladder 505 is fixedly connected inside the movable frame 504, and the diverter 4 is connected to the side of the first compression air bladder 505. The outer side of the threaded shaft 503 is spirally connected to the adjusting plate 501.

[0027] A first flexible pressure sensor 506 is installed on one side of the first compression airbag 505, and the outer side of the moving frame 504 is slidably connected to the adjusting plate 501.

[0028] During the process of collecting blood from the sole of the newborn's foot, if there is an abscess lesion on the sole of the foot, the handle 502 can be turned to rotate the threaded shaft 503 and lock it in place with the threaded adjustment plate 501, thus restricting the displacement of the moving frame 504. This avoids the first compression airbag 505 inside the moving frame 504 from exerting a compression effect on the abscess area on the sole of the foot, achieving selective avoidance of the compression area and further ensuring the safety of the newborn's foot.

[0029] Also includes the following: By rotating the locking bolt 508, the adjusting plate 501 can be moved easily, so that multiple adjusting plates 501 are in the corresponding positions in sequence. At the same time, when the newborn's foot blisters are more severe, the rotating handle 502 in the corresponding position can be rotated so that the thread on the outside of the threaded shaft 503 on one side engages with the adjusting plate 501, thereby achieving the purpose of adjusting the moving frame 504. This prevents the first compression airbag 505 inside the moving frame 504 in this part from moving down and compressing the diseased area such as the newborn's foot blisters, which could cause it to rupture. When compression is applied to the corresponding area of ​​the newborn's foot, the position of the moving frame 504 can be adjusted by the thread on the outside of the threaded shaft 503 and the adjusting plate 501, so that the first compression airbag 505 inside is close to the newborn's foot area. After inflation, the side is compressed. At the same time, the first flexible pressure sensor 506 is set to detect pressure data to avoid excessive compression from aggravating the damage to the local area of ​​the newborn's foot. Multiple third solenoid valves 509 are also provided. When the first compression airbag 505 at the corresponding position is inflated, its first flexible pressure sensor 506 detects the corresponding pressure data. When the data reaches the set threshold, the next third solenoid valve 509 is activated, thereby realizing the sequential vertical compression of the newborn's foot area. At the same time, it will not push and squeeze like medical staff, which may cause damage to the lesion area of ​​the newborn's foot.

[0030] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 3 Specifically, the newborn foot adjustment module 3 includes a side frame 301, an air pump device 302, and an exhaust pipe 303. The side of the side frame 301 is fixedly connected to the protective pad 1. A partition 307 is installed inside the side frame 301. An air pump device 302 is fixedly connected to the side frame 301 on one side of the partition 307. The output end of the air pump device 302 is connected to the exhaust pipe 303. The other end of the exhaust pipe 303 is connected to the diverter 4. A first solenoid valve 304 is also installed on the outside of the exhaust pipe 303. A hot air conveying pipe 309 is also connected above the side frame 301. The hot air conveying pipe 309 is provided with multiple exhaust ends, which are distributed on one side of the inner wall of the foot support ring 2.

[0031] One side of the exhaust pipe 303 is connected to a diversion pipe 305, and two exhaust ports are led out from one side of the diversion pipe 305. The two exhaust ports pass through the partition 307 and are located on the upper and lower sides of the semiconductor heating and cooling component 308 inside the side frame 301. A second solenoid valve 306 is also installed on the outside of the diversion pipe 305.

[0032] The side of the side frame 301 is also connected to a deformable hose 310, and one end of the deformable hose 310 is connected to a hollow cover 311.

[0033] Before the blood collection operation begins, the temperature is controlled by the semiconductor heating and cooling component 308 inside the side frame 301. The hot air generated by the heating side of the semiconductor heating and cooling component 308 is delivered to the newborn's foot area through the hot air delivery pipe 309. The heat improves the blood circulation in the newborn's feet, creating favorable conditions for blood collection. At the same time, the cold air generated by the cooling side of the semiconductor heating and cooling component 308 is delivered to the cover 311 through the deformable hose 310 to apply a cold compress to the puncture area and reduce the stinging sensation caused by the puncture.

[0034] Also includes the following: By opening the first solenoid valve 304, the air pump device 302 is started to deliver air through the exhaust pipe 303 to inflate the newborn foot compression module 5, so as to gradually push it. At the same time, it works with the foot plate compression module 7 to further reduce the compression range, ensuring that the puncture point bleeds and facilitating subsequent blood collection. After the airbag inflation is completed, the first solenoid valve 304 is closed and the second solenoid valve 306 is opened. At this time, air can be discharged through the diversion pipe 305, blowing hot and cold air on both sides of the semiconductor heating and cooling component 308 respectively, so that the hot air can preheat the newborn's feet. The temperature of the heating zone is maintained at 37-39℃. It can also be used with an external shielding cloth to cover the outside of the newborn's foot compression module 5 to achieve local heat preservation. The temperature of the cooling zone is maintained at 22-26℃. The deformable hose 310 can be bent, and its position can be adjusted according to the actual situation, so that the cold air discharge area cover 311 is located in the puncture area where blood will be collected, for cold compress to reduce the pain caused by the puncture.
