Description

Technical Field

[0001] The present invention relates to the technical field of blood sample collection auxiliary equipment, and in particular to a multimodal analgesic device for infant heel blood sampling. Background Art

[0002] Pain, the fifth vital sign besides body temperature, pulse, respiration, and blood pressure, is mainly characterized by unpleasant emotional experiences and is mainly related to tissue damage. Procedural pain mostly refers to pain that occurs rapidly and is of short duration during clinical diagnosis, treatment, and nursing operations for the purpose of curing diseases and maintaining health. Since the physiological systems of premature infants are not fully developed, they inevitably need to undergo repeated painful stimulation such as foot blood sampling and venipuncture during treatment and monitoring in the neonatal intensive care unit. However, premature infants have a more acute neurochemical basis for perceiving pain, and their pain threshold and pain tolerance are lower than those of adults. Therefore, the pain during painful procedures is more persistent and intense. Excessive and persistent pain stimulation causes damage to the premature infant's neurological development, somatic sensation, and emotional components, leading to complications such as nutritional intolerance, hypoglycemia, and apnea, affecting their physiological and neurological development, and further forming long-term cognitive and behavioral disorders. In addition, during the operation, the infant cannot control the body independently, and the pain causes the infant's feet to move uncontrollably, affecting the blood collection operation and the puncture depth of the blood collection needle, causing greater harm to the infant. Therefore, early pain intervention for premature infants is extremely necessary.

[0003] The prior art provides many solutions for blood sampling pain intervention and limiting limb displacement. For example, the prior art KR1020190014352A discloses a venous blood sampler with a tourniquet. The invention involves a main body, two infrared LEDs that can project infants or animals, a silicon object fixing device, and the object fixing device can be an interval moving hanger interval control component. The arm or tail is automatically installed to help guide the infrared rays to the adjacent sensor and the blood vessels are compressed and used as a Tony tube. However, this blood sampling scheme tends to limit the blood sampling limb. Another example is the prior art KR102673234B1, which discloses a calibration device that can perform transdermal drug administration tests and blood sampling on animals. It can measure the weight of animals that can be stably fixed by excluding the drug administration site, improve the safety and work efficiency of the staff, and improve the reliability of the test results by minimizing the stimulation of the drug administration site. However, the above-mentioned prior arts all have room for improvement in reducing pain intervention and being applicable to blood sampling for infants and young children. Summary of the Invention

[0004] The purpose of the present invention is to provide a multimodal analgesia device for infant heel blood sampling, so as to solve the shortcomings of the existing technology in reducing the pain intervention of infant blood sampling and being suitable for infant blood sampling, achieve effective analgesia during infant heel blood sampling, reduce the uncontrollable movement of the infant's foot caused by pain, and reduce the harm caused to the infant by the blood sampling operation.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solution: a multimodal analgesia device for infant heel blood sampling, comprising: A first base body having a channel running through both ends thereof, one end of the channel being used to expose the baby's heel; The backing plate assembly is arranged on the inner wall of the channel of the first base body, The pad assembly comprises a first pad and a second pad stacked up and down, wherein the first pad and the second pad are connected via a connector; and a player is arranged on the first base.

[0006] The present invention arranges a player on the first substrate to play audio to form white noise soothing content, so as to distract the baby's attention with auditory stimulation and reduce the perception of pain; the first pad and the second pad of the pad assembly of the present invention form an elastic buffer structure through a connector, which provides a gentle pressure feeling through physical contact during blood collection, thereby achieving tactile analgesia, and cooperates with the white noise soothing of the player to achieve multimodal intervention to significantly enhance the analgesic effect. The through channel of the first substrate can stably fix the baby's foot, and the exposed end can accurately locate the blood collection site to avoid puncture depth deviation or repeated puncture due to foot movement; the pad assembly fits the inner wall of the channel, and the bending rod structure of the connector allows a small displacement between the pads, which can be adaptively adjusted according to the size of the baby's foot to ensure the fixation comfort and operational convenience of babies of different ages.

[0007] According to one embodiment of the present invention, the connector includes a first connecting plate fixedly connected to a first backing plate, a second connecting plate fixedly connected to a second backing plate, and the first and second connecting plates are connected by a bent rod. The first connecting plate has a hole in the middle, through which a fastener is connected to the first backing plate. For safety reasons, the fastener is a rubber screw. If the first backing plate is relatively thin, the first backing plate and the first connecting plate are connected by bonding. The second connecting plate has a hole in the middle, through which the fastener is connected to the second backing plate.

[0008] The pad assembly achieves elastic connection between the first pad and the second pad through a connector, which can produce small adaptive displacements as the baby's foot size or pressure changes, ensuring a fixed fit for babies of different ages. This not only avoids discomfort caused by excessive restraint, but also effectively limits uncontrollable movement of the foot, thereby improving the accuracy and safety of blood collection operations.

[0009] According to one embodiment of the present invention, the bending rod of the connector is connected to the first connecting plate at one end and perpendicularly connected to the second connecting plate at the other end. A flattened bent portion is provided in the middle of the bending rod. The width of the flattened bent portion is parallel to the plane in which the first and second pads are stacked, and the thickness is perpendicular to the plane. This increases the structural strength of the bend and reduces space usage. A spacing is provided between the first and second pads, and the connectors are evenly spaced between the first and second pads. One end of the bending rod of the connecting piece is connected to the first connecting plate, and the other end is perpendicularly connected to the second connecting plate. A flat bending part is provided in the middle, the width direction of which is parallel to the stacking plane of the first pad and the second pad, and the thickness direction is perpendicular to the stacking plane. The scheme of the present invention effectively disperses the shear force and bending moment through the L-shaped composite structure combined with the middle bend, increases the structural strength of the bend, and reduces the horizontal space occupancy due to the thickness direction being perpendicular to the stacking plane, making the device structure compact; the spacing distance between the first pad and the second pad is combined with the equally spaced connecting pieces to ensure that the first pad and the second pad are subjected to uniform force and synchronous elastic deformation, providing a moderate buffer space for the baby's foot, avoiding excessive compression or local pressure concentration, and can also dynamically fit the heel curvature with the foot movement, reducing mechanical restraint while limiting movement.

[0010] According to one embodiment of the present invention, a first limiting plate is provided at one end of a channel for exposing an infant's heel. The first limiting plate has an opening that allows the infant's heel to pass through. The first limiting plate is disposed at one end of the channel exposing the infant's heel. Its opening conforms to the contour of the infant's heel, accurately exposing the blood collection area, avoiding repeated punctures or tissue damage caused by positioning deviations, and improving puncture positioning accuracy. The edge of the opening forms an annular limiting structure with the heel, which, in conjunction with the first base through-channel, effectively limits the forward and backward, left and right displacement of the heel, enhancing foot stability and reducing the risk of uncontrolled puncture depth or needle deviation due to limb shaking.

[0011] According to one embodiment of the present invention, a first auxiliary plate is detachably connected to one side of the first limiting plate, and a side of the first auxiliary plate is connected to the first limiting plate via a mounting plate.

[0012] One side of the first retaining plate is detachably connected to the first auxiliary plate via a mounting plate, allowing for dynamic adjustment of the retaining range based on the size of the infant's foot. Specifically, the mounting plate allows for flexible adjustment of the auxiliary plate's position, such as lateral sliding or angle adjustment, to expand the retaining range for the infant's calf or ankle. This is particularly useful for premature infants with smaller foot diameters, enhancing limb fixation stability. The mounting plate is constructed of lightweight materials with a smooth contact surface, ensuring effective retaining and infant comfort.

[0013] According to one embodiment of the present invention, a fixed plate is provided below the first auxiliary plate, and one end of the fixed plate has an extension plate perpendicular to the surface of the first auxiliary plate, a chute is provided on the extension plate, and an L-shaped angle plate connected to the extension plate is provided at the end of the first auxiliary plate. The extension plate and the L-shaped angle plate are connected by fasteners, and the fasteners can move up and down in the chute. The fixed plate below the first auxiliary plate is flexibly adjusted through the cooperation of the extension plate and the L-shaped angle plate. Specifically, the chute on the extension plate is connected to the L-shaped angle plate at the end of the first auxiliary plate by fasteners, allowing the fasteners to move up and down in the chute, so that the auxiliary plate can be adjusted in height and angle to accurately adapt to the lower limb length, ankle curvature and blood collection operation requirements of different infants, especially to enhance the limiting fit for the developmental characteristics of the lower limbs of premature infants, and avoid insufficient exposure of the blood collection site or limb compression caused by fixed rigidity. The chute and fastener solution can be adjusted and locked as needed, and the adjustment and locking can be completed quickly without tools, shortening the operation time while ensuring that the auxiliary plate is stable and not loose.

[0014] According to one embodiment of the present invention, the first substrate is an elongated structure with a longitudinal channel extending through both ends along the length direction, and a first opening is provided on the upper surface of the first substrate. The first opening is an elliptical or arc-shaped notch, the long axis of which is consistent with the extension direction of the longitudinal channel, and the first opening is connected to the exposed end of the longitudinal channel. The first substrate adopts an elongated structure with a longitudinal channel extending through both ends along the length direction, and an elliptical or arc-shaped first opening is provided on the upper surface with the long axis consistent with the extension direction of the channel, and is connected to the exposed end of the longitudinal channel. The elongated longitudinal channel can longitudinally limit the infant's calf to the heel, forming a stable support. The elliptical or arc-shaped notch fits the physiological curve of the infant's calf to the heel, and the edges are chamfered to reduce the risk of compression and scratches, while allowing the limbs to rotate slightly to adapt to the natural posture, reducing the infant's stress response and improving comfort.

[0015] According to one embodiment of the present invention, a strap is provided at the edge of the first base. The strap can be attached to an external object, such as a bedside or operating table, to achieve flexible fixation in multiple scenarios. Specifically, the strap forms a mechanical connection by wrapping around the device, accommodating blood collection requirements in multiple positions, such as supine and side-lying, as found in settings such as neonatal intensive care units. It also resists the pulling force of infants struggling and prevents puncture deviation caused by device displacement.

[0016] According to one embodiment of the present invention, the channel of the first base body is filled with a strip body, and the strip body filled in the channel can further buffer the pressure on the limbs and improve the comfort of the baby during the operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention adopts the auditory stimulation of the player and the tactile pressure of the pad assembly to form multimodal analgesia synergy, combined with the first limiting plate and its detachable first auxiliary plate, and the precise dynamic limitation of the limiting assembly to improve the analgesic effect and puncture stability; the bending rod structure of the connecting part enhances strength and reduces space occupancy through mechanical optimization, and the equidistant distribution design ensures that the pad is uniformly stressed and elastically deformed synchronously, and is adaptable to different foot sizes; the straps realize external fixation in multiple scenarios, freeing the hands of medical staff. The device of the present invention can realize a standardized fixation process suitable for batch blood collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] Example 1: Attached picture Figure 1 -Attached Figure 7 As shown, the present invention provides a multimodal analgesia device for infant heel blood sampling, comprising: The first base 10 has a channel extending through the first and second ends thereof, one end of the channel being used to precisely expose the baby's heel; The pad assembly 50 is mounted on the inner wall of the channel of the first base 10. The assembly consists of a first pad 51 and a second pad 52 stacked up and down, and the two are elastically connected by a connector 53. In addition, a player 60 is integrated on the first base 10 to provide auditory stimulation for multimodal analgesia. The present invention arranges a player 60 on the first base 10 to play audio to form white noise soothing content, so as to distract the baby's attention with auditory stimulation and reduce pain perception. The first pad 51 and the second pad 52 of the pad assembly 50 of the present invention form an elastic buffer structure through the connector 53, which provides a gentle pressure feeling through physical contact during blood collection to achieve tactile analgesia, and cooperates with the white noise soothing of the player 60 to achieve multimodal intervention to significantly improve the analgesic effect. The through channel of the first base 10 can stably fix the baby's foot, and the exposed end can accurately locate the blood collection site to avoid puncture depth deviation or repeated puncture due to foot movement; the pad assembly 50 fits the inner wall of the channel, and the bending rod 532 structure of the connecting part 53 allows a small displacement between the pads, which can be adaptively adjusted according to the size of the baby's foot, ensuring the fixation comfort and operation convenience of babies of different age groups.

[0024] The connector 53 includes a first connecting plate 531 fixedly connected to the first backing plate 51, and a second connecting plate 533 fixedly connected to the second backing plate 52. The first and second connecting plates 531 and 533 are connected by a bent rod 532. The first connecting plate 531 has a hole in the middle, through which a fastener is connected to the first backing plate 51. For safety reasons, rubber screws are used as fasteners. If the first backing plate 51 is relatively thin, the first backing plate 51 and the first connecting plate 531 are connected by adhesive bonding. The second connecting plate 533 has a hole in the middle, through which a fastener is connected to the second backing plate 52.

[0025] The pad assembly 50 realizes elastic connection between the first pad 51 and the second pad 52 through the connecting piece 53, and can produce a small adaptive displacement as the size or pressure of the baby's foot changes, ensuring a fixed fit for babies of different ages, avoiding discomfort caused by excessive restraint, and effectively limiting uncontrollable movement of the feet, thereby improving the accuracy and safety of blood collection operations.

[0026] The bent rod 532 of the connector 53 is connected to the first connecting plate 531 at one end and perpendicularly connected to the second connecting plate 533 at the other end. A flattened bent portion is located in the middle of the rod. The width of the bent portion is parallel to the plane where the first and second backing plates 51, 52 are stacked, and the thickness is perpendicular to that plane. This increases the structural strength of the bent portion and reduces space usage. A distance is provided between the first and second backing plates 51, 52, and the connectors 53 are evenly spaced between them. One end of the bending rod 532 of the connecting member 53 is connected to the first connecting plate 531 and the other end is perpendicularly connected to the second connecting plate 533. A flat bending portion is provided in the middle, the width direction of which is parallel to the stacking plane of the first pad 51 and the second pad 52, and the thickness direction is perpendicular to the stacking plane. The scheme of the present invention effectively disperses the shear force and bending moment through the L-shaped composite structure combined with the middle bend, increases the structural strength of the bend, and reduces the horizontal space occupancy due to the thickness direction being perpendicular to the stacking plane, making the device structure compact; the spacing distance between the first pad 51 and the second pad 52 is combined with the equally spaced connecting members 53, ensuring that the first pad 51 and the second pad 52 are evenly stressed and elastically deformed synchronously, providing a moderate buffer space for the baby's foot, avoiding excessive compression or local pressure concentration, and can also dynamically fit the heel curvature with the movement of the foot, reducing the sense of mechanical restraint while restricting movement.

[0027] A first stopper 20 is provided at one end of the channel for exposing the infant's heel. The first stopper 20 has an opening that allows the infant's heel to pass through. The first stopper 20, located at one end of the channel, conforms to the contour of the infant's heel, accurately exposing the blood collection area, preventing repeated punctures or tissue damage caused by positioning deviations, and improving puncture positioning accuracy. The edge of the opening forms a ring-shaped stopper with the heel, which, in conjunction with the first base 10 through the channel, effectively limits the heel's forward and backward and left and right movement, enhancing foot stability and reducing the risk of loss of control over puncture depth or needle deviation due to limb movement.

[0028] A first auxiliary plate 30 is detachably connected to one side of the first limiting plate 20. The first auxiliary plate 30 is connected to the first limiting plate 20 via a lateral mounting plate 31. The first limiting plate 20 is detachably connected to the first auxiliary plate 30 via the mounting plate 31, allowing for dynamic adjustment of the limiting range based on the size of the infant's foot. Specifically, the mounting plate 31 allows for flexible adjustment of the auxiliary plate's installation position, such as through lateral sliding or angle adjustment, to expand the limiting range for the infant's calf or ankle. This is particularly suitable for premature infants with smaller foot diameters, enhancing the stability of limb fixation. The mounting plate 31 is constructed of lightweight materials with a smooth contact surface to ensure both effective limiting and infant comfort.

[0029] A fixed plate 32 is provided below the first auxiliary plate 30. An extension plate 33 is provided at one end of the fixed plate 32, extending perpendicularly to the surface of the first auxiliary plate 30. A slot is provided on the extension plate 33, and an L-shaped angle plate is provided at the end of the first auxiliary plate 30, connected to the extension plate 33. The extension plate 33 and the L-shaped angle plate are connected by fasteners, and the fasteners can move up and down within the slots. The fixed plate 32 below the first auxiliary plate 30 is flexibly adjusted through the cooperation of the extension plate 33 and the L-shaped angle plate. Specifically, the slot on the extension plate 33 is connected to the L-shaped angle plate at the end of the first auxiliary plate 30 by fasteners, allowing the fasteners to move up and down within the slots, allowing the auxiliary plate to be adjusted in height and angle to precisely adapt to the lower limb length, ankle curvature, and blood collection requirements of different infants. In particular, the limited fit is enhanced to address the developmental characteristics of the lower limbs of premature infants, avoiding insufficient exposure of the blood collection site or limb compression caused by rigid fixation. The slide and fastener solution can be adjusted and locked as needed. Adjustment and locking can be completed quickly without tools, shortening operation time while ensuring that the auxiliary plate is stable and not loose.

[0030] The first base 10 is an elongated structure with a longitudinal channel running through its two ends along its length. A first opening 11 is provided on the upper surface of the first base 10. The first opening 11 is an elliptical or arc-shaped notch, whose long axis is consistent with the extension direction of the longitudinal channel, and the first opening 11 is connected to the exposed end of the longitudinal channel. The first base 10 adopts an elongated structure with a longitudinal channel running through its two ends along its length. An elliptical or arc-shaped first opening 11 is provided on the upper surface with the long axis consistent with the extension direction of the channel, and is connected to the exposed end of the longitudinal channel. The elongated longitudinal channel can longitudinally limit the infant's calf to the heel, forming a stable support. The elliptical or arc-shaped notch fits the physiological curve of the infant's calf to the heel, and the edges are chamfered to reduce the risk of compression and scratches. At the same time, it allows slight rotation of the limbs to adapt to the natural posture, reducing the infant's stress response and improving comfort.

[0031] The first base 10 is provided with a strap 40 at the edge. The strap 40 at the edge of the first base 10 can be tied to an external object such as a bedside or operating table, achieving flexible fixation in multiple scenarios. Specifically, the strap 40 is formed by wrapping around the body to form a mechanical connection, adapting to the needs of blood collection in multiple positions such as supine and side-lying in settings such as neonatal intensive care units, resisting the pulling force of the infant's struggle and preventing puncture deviation caused by device displacement.

[0032] The channel of the first base body 10 is filled with strips, which can further buffer the pressure on the limbs and improve the comfort of the baby during the operation.

[0033] Example 2: See the instructions attached Figure 7 -Attached Figure 10On one side of the first auxiliary plate 30, a limit assembly 70 is provided that can rotate relative to the first auxiliary plate 30. The limit assembly 70 includes a second limit plate 75. One side of the second limit plate 75 has an extension rod. The two sections of the extension rod are rotatably connected to a rotating block 73. The connection structure between the two is a toothed ratchet mechanism. A limit link 72 is provided at the other end of the rotating block 73. The end of the limit link 72 is connected to the L-shaped angle plate of the first auxiliary plate 30. The limit assembly 70 on the side of the first auxiliary plate 30 achieves efficient and practical technical effects through the ingenious design of the toothed ratchet mechanism and the rotating link. Through the toothed ratchet mechanism connecting the extension rod of the second limit plate 75 to the rotating block 73, the limit assembly 70 can be flexibly adjusted between multiple angles and quickly locked to accommodate different positioning postures of the infant's lower limbs. The limit link 72 cooperates with the L-shaped angle plate to precisely fit the contours of the limb, effectively fixing premature infants with abnormal muscle tone. The operating mode is adjusted as needed and then locked. It can be quickly adjusted with one hand without tools, which greatly shortens the operation time. After locking, the ratchet engagement structure and rigid connecting rod ensure that the limit is stable to prevent loosening due to the baby's struggle.

[0034] An auxiliary limiting plate 71 is connected above the second limiting plate 75 through a support member 74. The support member 74 includes a supporting base plate 741 connected to the second limiting plate 75. An optical axis 743 is provided on the supporting base plate 74. Two sliding blocks 744 that can slide relative to the optical axis 743 are provided on the optical axis 743. The ends of the sliding blocks 744 are connected to the support rods 742 of the X-mounted structure. The support rods 742 are composed of two cross-connected rod bodies, and the cross connection is pin-connected. The support rods 742 are divided into two groups, which are respectively connected to the two sections of the sliding blocks 744. A sliding block 744 is also provided at the upper end of the support rod 742, and the sliding block 744 at the upper end is connected to the auxiliary limiting plate 71.

[0035] The support member 74 between the second limit plate 75 and the auxiliary limit plate 71, the optical axis 743 cooperates with the sliding block 744 and is combined with two sets of cross-pinned support rods 742 to form an X-shaped linkage lifting structure, which can synchronously adjust the height and lateral spacing of the auxiliary limit plate 71 to adapt to the lower limb characteristics of different babies, ensure the fit and avoid excessive compression. The sliding adjustment that does not require tool operation can automatically lock the angle in conjunction with the support rod to form a stable triangular support, ensuring that the second limit plate 75 and the auxiliary limit plate 71 are stable and not offset, and effectively disperse the force. In addition, it should be noted that the various components of the support member adopt rounded corners and damping gaskets to prevent scratches and accidental sliding.

[0036] Example 3: See attached Figure 1 As shown, the player 60 is embedded in the upper surface or side edge of the first base 10, and the specific connection method can be slot installation, magnetic installation, or threaded hole installation with screws.

[0037] The power cord or data cable of the player 60 is connected to an external power supply or control module through a concealed wire duct preset within the first base 10. The opening of the wire duct is sealed with a rubber plug to prevent liquids such as disinfectants from infiltrating and affecting circuit safety. At the same time, the surface of the device is kept smooth to reduce the risk of potential scratches to the baby. The player 60 uses a miniature intelligent audio player with a built-in storage module with a capacity of 8GB, an audio decoding chip and a speaker. It supports common audio formats such as MP3 and WAV. It has a volume of 5cm×3cm×1cm and weighs 20g. Physical buttons or touch panels are set on the side of the first base 10 to support the following functions: play, pause, previous song, next song, and volume adjustment. At the same time, the playback content can be remotely controlled by connecting to an external terminal via Bluetooth, improving operational convenience.

[0038] The white noise within the player 60 includes, but is not limited to, natural sounds, heartbeats, and gentle hushing, as well as sounds like running water, waves, and wind. A sound guide hole is provided within the first base 10, with the speaker facing the baby's head to prevent direct irritation of the heel blood collection site. The inner wall of the sound guide hole is covered with sound-absorbing cotton to reduce high-frequency noise reflection and ensure a soft and uniform sound.
