Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blood sample collection auxiliary equipment, in particular to a multi-modal analgesic device for heel blood collection of infants. BACKGROUND

[0002] Pain, as the fifth vital sign in addition to body temperature, pulse, respiration, and blood pressure, is mainly characterized by an unpleasant emotional experience, and is mainly related to tissue damage. The procedural pain refers to the pain caused in the process of clinical diagnosis, treatment and nursing operation, which is rapid in onset and short in duration. Since the physiological systems of premature infants are not fully developed, it is inevitable for them to receive repeated painful stimuli such as heel blood collection and intravenous puncture during treatment and monitoring in the neonatal intensive care unit. However, premature infants have more sensitive neurochemical basis for perceiving pain, and their pain threshold and pain tolerance are lower than those of adults. Therefore, the pain is more persistent and intense during the painful operation process. Excessive and persistent pain stimulation causes damage to the neural development, somatosensory and emotional components of premature infants, leading to complications such as nutritional intolerance, hypoglycemia, and apnea, affecting their physiological and neural development, and further forming long-term cognitive and behavioral disorders. Moreover, during the operation process, the infant cannot control the body due to pain, which affects the blood collection operation and the depth of the blood collection needle, causing greater harm to the infant. Therefore, it is extremely necessary to intervene in the pain of premature infants at an early stage.

[0003] There are many solutions in the prior art for pain intervention and limb displacement limitation during blood collection. For example, the prior art KR1020190014352A discloses a venous blood collector with a tourniquet. The invention relates to a main body, two infrared LEDs that can project an infant or an animal, a silicon object fixing device, and an object fixing device that can be a spacer moving hanger interval control part. The arm or tail is automatically installed to help the infrared line guide onto the adjacent sensor and the blood vessel is compressed and used as a toni tube. However, this blood collection scheme is biased towards limb positioning for blood collection. For example, the prior art KR102673234B1 discloses a correction device for testing and blood collection of transdermal administration to animals. It can measure the weight of the animal that can be stably fixed by excluding the 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 administration site. However, the above-mentioned prior art still has room for improvement in terms of reducing pain intervention and applying to blood collection of infants. SUMMARY

[0004] The purpose of the present application is to provide a multi-modal analgesic device for heel blood sampling of infants to solve the problems in the prior art, such as reducing the pain intervention of infants during blood sampling and being suitable for blood sampling of infants, so as to effectively relieve the pain of infants during heel blood sampling, reduce the uncontrollable movement of the feet of infants due to pain, and reduce the harm caused to infants by blood sampling operation.

[0005] To solve the above technical problems, the present application specifically provides the following technical scheme: a multi-modal analgesic device for heel blood sampling of infants, comprising:

[0006] A first base body has a channel passing through both ends thereof, and one end of the channel is used for exposing the heel of an infant;

[0007] A pad assembly is arranged on the inner wall of the channel of the first base body,

[0008] The pad assembly comprises a first pad and a second pad stacked one above the other, and the first pad and the second pad are connected by a connecting piece; and the first base body is provided with a player.

[0009] The player arranged on the first base body can play audio to form white noise soothing content, so as to distract the attention of the infant by auditory stimulation and reduce the perception of pain; the first pad and the second pad of the pad assembly form an elastic buffer structure through the connecting piece, and a soft compression feeling is provided by physical contact during blood sampling, so as to realize tactile analgesia, and the white noise soothing of the player is combined to realize multi-modal intervention, thereby significantly improving the analgesic effect. The through channel of the first base body can stably fix the feet of the infant, accurately position the blood sampling site at the exposed end, and avoid deviation of the puncture depth or repeated puncture caused by the movement of the feet; the pad assembly is attached to the inner wall of the channel, and the bending rod structure of the connecting piece allows small displacement between the pads, so that the pad assembly can be adjusted according to the size of the feet of the infant, ensuring the comfort and convenience of the operation of infants of different ages.

[0010] According to an embodiment of the present application, the connecting piece comprises a first connecting plate fixedly connected with the first pad, and a second connecting plate fixedly connected with the second pad, and the first connecting plate and the second connecting plate are connected by a bending rod. The middle part of the first connecting plate has a hole body, and a fastener forms a connection relationship with the first pad through the hole body. In view of safety, the fastener is selected to be a rubber screw. In the case that the thickness of the first pad is low, the connection mode of the first pad and the first connecting plate is adhesion. The middle part of the second connecting plate has a hole body, and a fastener forms a connection relationship with the second pad through the hole body.

[0011] The pad assembly realizes elastic connection of the first pad and the second pad through the connecting piece, can produce small adaptive displacement according to the size or pressure change of the feet of the infant, and ensures the fixing degree of infants of different months, so as to avoid discomfort caused by excessive restraint and effectively limit the uncontrollable movement of the feet, thereby improving the accuracy and safety of blood sampling operation.

[0012] According to an embodiment of the present application, one end of the bending rod of the connecting piece is connected with the first connecting plate, the other end is connected with the second connecting plate perpendicularly, and a flat bending part is arranged in the middle of the bending rod. The width direction of the flat bending part is parallel to the stacking plane of the first pad plate and the second pad plate, and the thickness direction is perpendicular to the stacking plane, so as to increase the structural strength of the bending part and reduce the occupied space. The first pad plate and the second pad plate have a spacing distance, and the connecting pieces are distributed equidistantly between the first pad plate and the second pad plate. One end of the bending rod of the connecting piece is connected with the first connecting plate, the other end is connected with the second connecting plate perpendicularly, and a flat bending part is arranged in the middle of the bending rod. The width direction of the flat bending part is parallel to the stacking plane of the first pad plate and the second pad plate, and the thickness direction is perpendicular to the stacking plane. The scheme of the present application effectively disperses the shear force and bending moment through the combination of the L-shaped structure and the middle bending part, increases the structural strength of the bending part, reduces the transverse space occupation due to the thickness direction being perpendicular to the stacking plane, and makes the device structure compact. The spacing distance between the first pad plate and the second pad plate matches the equidistantly distributed connecting pieces, ensures uniform and synchronous elastic deformation of the first pad plate and the second pad plate, provides a moderate buffer space for the baby's foot, avoids excessive compression or local pressure concentration, and can dynamically fit the heel curvature according to the foot movement, thereby reducing the mechanical restraint feeling while limiting the movement.

The edge of the opening and the heel form a ring-shaped limiting structure, which cooperates with the through channel of the first base body to effectively limit the forward and backward displacement and the left and right displacement of the heel, thereby enhancing the stability of the foot and reducing the risk of out-of-control puncture depth or needle deviation caused by limb shaking.

[0014] According to an embodiment of the present application, a first auxiliary plate is detachably connected to one side of the first limiting plate, and the first auxiliary plate is connected to the first limiting plate through a mounting plate body.

[0015] The first auxiliary plate is detachably connected to one side of the first limiting plate through a mounting plate body, so that the limiting range can be dynamically adjusted according to the size of the baby's foot. Specifically, the mounting position of the auxiliary plate can be flexibly adjusted, such as transverse sliding or angle fine adjustment, so as to expand the limiting range of the baby's calf or ankle, especially for premature babies with small foot diameters, thereby improving the stability of the limb fixation. The mounting plate body is made of light material and has a smooth contact surface, so as to ensure the limiting effect and ensure the comfort of the baby.

[0016] According to an embodiment of the present application, a fixing plate is arranged below the first auxiliary plate, one end of the fixing plate is provided with an extension plate perpendicular to the surface of the first auxiliary plate, a sliding groove is formed in the extension plate, and the end of the first auxiliary plate is provided with an L-shaped angle plate connected with the extension plate. The extension plate and the L-shaped angle plate are connected through fasteners, and the fasteners can be displaced up and down in the sliding groove. The fixing plate below the first auxiliary plate is flexibly adjusted through the cooperation of the extension plate and the L-shaped angle plate. Specifically, the sliding groove in the extension plate and the L-shaped angle plate at the end of the first auxiliary plate are connected through fasteners, and the fasteners are allowed to be displaced up and down in the sliding groove, so that the auxiliary plate can be adjusted in height and angle, and accurately adapt to the length of the lower limbs, the ankle curvature and the blood sampling operation requirements of different infants. Especially for the lower limb development characteristics of premature infants, the limit fit is enhanced to avoid insufficient exposure of the blood sampling site or limb compression caused by rigid fixation. The scheme of the sliding groove and the fastener can realize on-demand adjustment and locking, and the adjustment and locking can be quickly completed without tools, which shortens the operation time and ensures the stability of the auxiliary plate.

The fixed plate 32 below the first auxiliary plate 30 is flexibly adjusted by the cooperation of the extension plate 33 and the L-shaped angle plate. Specifically, the sliding groove on the extension plate 33 and the L-shaped angle plate at the end of the first auxiliary plate 30 are connected by a fastener, which allows the fastener to be displaced up and down in the sliding groove, so that the auxiliary plate can be adjusted in height and angle to accurately adapt to the length of the lower limbs, the ankle curvature and the blood sampling operation requirements of different infants.

[0048] Embodiment 2:

[0049] Referring to the drawings Figure 7 -Appendix Figure 10A limiting component 70, capable of rotating relative to the first auxiliary plate 30, is provided on one side of the first auxiliary plate 30. The limiting component 70 includes a second limiting plate 75, one side of which has an extension rod. Rotating blocks 73 are rotatably connected to both ends of the extension rod via a toothed ratchet mechanism. A limiting link 72 is located at the other end of the rotating block 73, and its end is connected to the L-shaped corner plate of the first auxiliary plate 30. The limiting component 70 on one 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. The connection between the extension rod of the second limiting plate 75 and the toothed ratchet mechanism of the rotating block 73 allows for flexible adjustment and quick locking across multiple angle settings, adapting to different lower limb positions of infants. The limiting link 72, in conjunction with the L-shaped corner plate, precisely conforms to the limb contour, effectively fixing infants with abnormal muscle tone, especially those born prematurely. It achieves an operation mode of adjusting and locking as needed, allowing for quick one-handed adjustment without tools, significantly reducing operation time. Furthermore, the ratchet engagement structure and rigid linkage ensure stable positioning after locking, preventing loosening due to the baby's struggle.

[0050] An auxiliary limiting plate 71 is connected above the second limiting plate 75 via a support member 74. The support member 74 includes a support base plate 741 connected to the second limiting plate 75. The support base plate 74 is provided with an optical axis 743. 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-mount structure. The support rods 742 are composed of two cross-connected rods. The cross-connection is achieved by a pin connection. The support rods 742 are in two sets and are respectively connected to the two ends of the sliding blocks 744. Sliding blocks 744 are also provided at the upper end of the support rods 742. The upper sliding blocks 744 are connected to the auxiliary limiting plate 71.

This structure allows for synchronous adjustment of the height and lateral spacing of the auxiliary limiting plate 71, adapting to the lower limb characteristics of different infants, ensuring a good fit, and preventing excessive pressure. The tool-free sliding adjustment, combined with the support rods, automatically locks the angle, forming a stable triangular support to ensure the second limiting plate 75 and the auxiliary limiting plate 71 remain stable and do not shift, effectively distributing force. Furthermore, it should be noted that all components of the support member are rounded and fitted with damping pads to prevent scratches and accidental slippage.
