[0016] By arranging the first frame, the second frame, the clip, the Velcro and the first perforation, the syringe body can be installed quickly and stably. The first frame and the second frame have a tightening tendency when installed; with the help of this tightening tendency, the two clips can clamp the shoulders and head of the baby; the tightening effect of the first frame can be further enhanced by tightening the Velcro.
[0017] By arranging a slide groove, a slider, a limiting ring and a limiting frame in the position adjustment mechanism, the limiting frame can slightly squeeze the needle of the syringe body near the recess, so that when the needle is injected, the syringe body is used to guide the limit, and the limiting frame also has a certain buffering effect on the syringe body, further reducing the discomfort of infants and young children during the BCG injection process.

[0018] By setting up a third skeleton, a third connecting strip, a pressing piece and an auxiliary piece, the third skeleton and the pressing piece cooperate with each other to generate a stronger restorative force after deformation, and then use the restorative force to compress the needle of the syringe body. The pressing piece and the auxiliary piece can assist in pressing and limiting the needle, effectively preventing the needle from deviating, and making the syringe body more stable during use. At the same time, this design avoids direct contact between the hands of medical staff and the needle, reduces the risk of infection, and further ensures the comfort and safety of infants during BCG injection.
[0019] By providing a first insert, a fourth frame and a fifth frame in the angle adjustment mechanism, the first insert and the fourth frame will deform and bend together, causing the angle between the limit ring and the limit frame to change, and the injection angle of the syringe body can be adjusted so that it can be at the optimal angle for injection operation, effectively ensuring the accuracy of the injection, while also reducing the discomfort of the infant, and the fifth frame and the first insert can also be used to adjust the distance between the limit ring and the third frame, thereby achieving the adjustment of the injection depth of the syringe body.
[0020] By providing the second slot and the second insertion strip, the second insertion strip can be used to cause the end of the first insertion strip close to the second insertion strip to expand and deform, thereby prompting the slider to have a further expansion trend, and its outer wall then squeezes the inner wall of the slide groove, so that the slider is stably fixed at the injection positioning position in the slide groove.
[0021] This device can ensure injection stability through the adjustment of position, angle and depth, as well as the guiding and limiting effects of various components on the syringe body, greatly reducing the discomfort of infants during BCG injection, while improving operational safety and convenience.

[0031] like Figures 1 to 3 and Figures 5 to 7As shown, an embodiment of the present invention provides a positioning device for infant vaccination, comprising a first frame 1, a second frame 2 being fixedly connected to one side of the first frame 1, a clip 3 being fixedly connected to one side of the first frame 1, a Velcro 4 being provided on the side of the first frame 1 away from the clip 3, a first through-hole 5 being provided on the first frame 1 and matching the shape of the Velcro 4, a syringe body 32 being provided on one side of the first frame 1; a position adjustment mechanism, the position adjustment mechanism being used to adjust the injection position of the syringe body 32, the position adjustment mechanism being connected to the second frame 2; an angle adjustment mechanism, the angle adjustment mechanism being used to adjust the injection angle of the syringe body 32, the angle adjustment mechanism being connected to the position adjustment mechanism, and there being two clips 3; the Velcro 4 and the syringe body 32 are both existing mature technologies, so their working principles and specific structures are not described in detail here, the syringe body 32 is connected to the second frame 2 through the position adjustment mechanism, and the device is provided through the first frame 1 and the second frame 2. 2. The coordinated use of the clips 3 and the Velcro 4 can realize the rapid and stable installation of the above-mentioned adjustment mechanism, which is specifically as follows: the first frame 1 and the second frame 2 can be quickly installed and fixed at the position of the baby's upper arm near the deltoid muscle, and the two have a tightening tendency when installed; with the help of this tightening tendency, the two clips 3 can clamp the baby's shoulders and head; then the two ends of the Velcro 4 are inserted into the first through-hole 5 and tightened, which can further enhance the tightening effect of the first frame 1; after installation is completed, the injection position of the syringe body 32 can be further adjusted by the position adjustment mechanism, and the angle adjustment mechanism can be used to adjust the angle between the syringe body 32 and the baby's arm, so that the syringe body 32 is at the optimal angle and position for the injection operation; at the same time, the position adjustment mechanism and the angle adjustment mechanism can also guide and limit the injection operation of the syringe body 32, ensure the stability of the injection, and greatly reduce the discomfort of the baby caused by the doctor's lack of experience or hand tremors during the BCG injection process; Optionally, during the procedure, two ultrasound diagnostic methods can be used to obtain relevant parameters of the neonatal deltoid muscle injection site. Two-dimensional ultrasound diagnosis: Using a high-resolution two-dimensional ultrasound system equipped with a high-frequency probe suitable for the neonatal's anatomy, the neonate is placed in a supine or lateral position and remains still. After fully exposing the deltoid muscle, the ultrasound probe is gently placed over the area. The probe angle and position are adjusted to obtain a clear image of the deltoid muscle. The anterior, posterior, superior, and inferior edges of the deltoid muscle are then identified on the image, and parameters such as thickness, length, and width are measured. Three-dimensional ultrasound diagnosis: Using an ultrasound system with three-dimensional ultrasound imaging capabilities and the appropriate probe, the neonate's position is adjusted to facilitate visualization of the deltoid muscle. Then, three-dimensional ultrasound mode is activated to scan the area and obtain three-dimensional image data. Specific software analysis tools can be used to observe the deltoid muscle morphology from different angles and measure various parameters. Three-dimensional ultrasound provides more comprehensive and comprehensive structural information. The aforementioned measurement and analysis instruments are currently mature technologies, and their working principles and specific structures are not detailed here.
[0032] Furthermore, the outline of the first skeleton 1 is adapted to the outline of the infant's upper arm, so that the first skeleton 1 can be more stably fixed on the infant's upper arm. The second skeleton 2 is an arc-shaped structure that bulges away from the first skeleton 1, so that there is space between the second skeleton 2 and the infant's upper arm, which is convenient for adjusting the position and angle of the syringe body 32. The first skeleton 1 and the second skeleton 2 are integrally constructed, and the integral structure has better stability and is convenient for production and transportation.
[0033] like Figures 2 to 4 and Figures 7 to 11As shown, the position adjustment mechanism includes a slider 7 mounted on the second frame 2, a slide groove 6 adapted to the shape of the slider 7 is provided on the second frame 2, a first slot 13 is provided on the slide groove 6, a first insertion strip 14 adapted to its shape is inserted in the first slot 13, and the end of the first insertion strip 14 away from the slide groove 6 is fixedly connected to a limiting ring 15 adapted to the shape of the syringe body 32, the side of the limiting ring 15 away from the first insertion strip 14 is fixedly connected to a first connecting strip 16, and the side of the first connecting strip 16 away from the limiting ring 15 is fixedly connected to a limiting frame 17 adapted to the shape of the syringe body 32. When operating, first move the syringe body 32 The part of the body 32 close to the needle passes through the limiting ring 15, and then the needle end of the syringe body 32 is inserted into the limiting frame 17, so that the needle tube of the syringe body 32 is smoothly placed inside the limiting ring 15; since the slider 7 is set in the slide groove 6, and the limiting frame 17 is fixedly connected to the limiting ring 15 through the first connecting strip 16, and the limiting ring 15 is connected to the slide groove 6 through the first insertion strip 14, the installation position of the syringe body 32 can be flexibly adjusted by adjusting the position of the slider 7 in the slide groove 6, so that the syringe body 32 can be accurately placed in the optimal injection position, which not only ensures the safety of the injection process, but also effectively reduces the discomfort of the baby during injection.
[0034] Furthermore, the cross-sections of the slide groove 6 and the slider 7 are both T-shaped, which ensures that the slider 7 will not slide out of the slide groove 6 during the sliding process of the slider 7 in the slide groove 6. A buffer cavity 31 is provided on the slide groove 6, so that when the first insertion strip 14 is inserted into the first slot 13, the buffer cavity 31 can produce a certain expansion deformation, so that the first insertion strip 14 can be more conveniently inserted into the first slot 13, thereby quickly connecting the slide groove 6 to the syringe body 32. At the same time, under the action of the expansion of the buffer cavity 31, the outer wall of the slide groove 6 squeezes the slider 7. The first insertion strip 14 is an arc-shaped structure and is made of plastic material, so that the first insertion strip 14 can be easily deformed and bent in the convex direction of the first insertion strip 14 under the action of external force. The first insertion strip 14 is provided with a first weakened portion on the side close to the limit ring 15. 28, so that the first insert 14 is deformed first from the first weakened portion 28 under the action of external force, the limiting ring 15, the first connecting strip 16 and the limiting frame 17 are an integrated structure, the integrated structure has good stability, and is relatively convenient to produce and transport. Lightweight grooves 18 are equidistantly arranged in an annular shape on the limiting frame 17, which reduces the weight of the limiting frame 17 and enhances the deformation ability of the limiting frame 17. A recess 19 is provided on the limiting frame 17, so that the limiting frame 17 can slightly squeeze the needle of the syringe body 32 near the recess 19, so that when the needle is injected, the syringe body 32 is used to guide the limit, and the limiting frame 17 also has a certain buffering effect on the syringe body 32, further reducing the discomfort of infants and young children during the BCG injection process.
[0035] like Figures 1 to 4 and Figures 7 to 11 As shown, the slider 7 is fixedly connected to the third frame 8 on the side away from the second frame 2, and the third frame 8 is fixedly connected to the pressing piece 9 on the side away from the slide groove 6. The four corners of the pressing piece 9 are provided with auxiliary pieces 10, and the third frame 8 is fixedly connected to the third connecting strip 29. The third connecting strip 29 is provided with a second weakened portion 30, a convex portion 11 is provided on the pressing piece 9, and second perforations 12 are equidistantly provided on the pressing piece 9. During use, the pressing piece 9 and the auxiliary piece 10 will come into contact with the upper arm of the infant. At this time, the third frame 8 and the third connecting strip 29 are bent and deformed, and the restorative elastic force generated can make the pressing piece 9 and the auxiliary piece 10 tightly It fits the baby's upper arm. Since the pressing piece 9 is provided with a protrusion 11, a small gap is left near the position of the pressing piece 9 near the protrusion 11. When the syringe body 32 performs the injection operation, the needle will pass through the corresponding second perforation 12 and pierce the baby's skin. After the puncture is completed, the pressing piece 9 and the auxiliary piece 10 can assist in pressing and limiting the needle, effectively preventing the needle from deviating, and making the syringe body 32 more stable during use. At the same time, this design avoids direct contact between the hands of medical staff and the needle, reduces the risk of infection, and further ensures the comfort and safety of the baby during the BCG injection process.
[0036] Furthermore, the third skeleton 8 and the third connecting strip 29 form an H shape, so that after the third skeleton 8 and the pressing piece 9 are deformed, they cooperate with each other to produce a stronger restorative elastic force, and then use the restorative elastic force to compress the needle of the syringe body 32. The third skeleton 8 and the third connecting strip 29 are integrally constructed. The integral structure has good stability and is relatively convenient to produce and transport. The third skeleton 8 and the third connecting strip 29 are both arc-shaped mechanisms, so that the third skeleton 8 and the third connecting strip 29 are more likely to deform and bend toward their convex parts under the action of external force. The shape of the pressing piece 9 and the auxiliary piece 10 is adapted to the contour of the baby's upper arm, so that the pressing piece 9 and the auxiliary piece 10 can better fit the baby's upper arm when subjected to force. The pressing piece 9 and the auxiliary piece 10 are made of rubber material, which is soft and skin-friendly, reducing the baby's discomfort.
[0037] like Figures 7 to 11As shown, the angle adjustment mechanism includes a fourth frame 20 installed on the limit ring 15, and the side of the fourth frame 20 away from the limit ring 15 is fixedly connected to the fifth frame 21, and the side of the fifth frame 21 close to the third frame 8 is fixedly connected to the limit block 22. The third frame 8 is equidistantly provided with limit grooves 23 that are adapted to the shape of the limit blocks 22. When the fifth frame 21 is pulled, the first insertion strip 14 and the fourth frame 20 will deform and bend together, causing the angle of the limit ring 15 connected to the first insertion strip 14 and the fourth frame 20 to change, and the angle of the limit frame 17 will change accordingly. At this time, the limit block 22 is inserted into the limit groove 23 at different positions on the third frame 8, so that the angle adjustment of the limit ring 15 and the limit frame 17 can be quickly completed, and then the injection angle of the syringe body 32 can be adjusted so that it can be at the optimal angle for injection operation, effectively ensuring the accuracy of the injection, and also reducing the discomfort of the baby.
[0038] Furthermore, the fourth frame 20 and the fifth frame 21 are integrally formed, and the integral structure has good stability and is convenient to produce and transport. The fourth frame 20 and the fifth frame 21 form a Y shape, and there are two limit blocks 22. The Y-shaped structure design is adopted, which makes the two limit blocks 22 on the fifth frame 21 clamp the third frame 8 when they are inserted into the limit grooves 23; the limit blocks 22 are connected to the limit grooves 23 by the clamping, so that the fifth frame 21 is stably connected to the third frame 8; because the length of the fifth frame 21 is greater than the limit grooves 23, the fifth frame 21 and the first insertion strip 14 are pulled, so that the limit blocks 22 on the fifth frame 21 are clamped into the limit grooves 23 at different positions, so that the depth of the first insertion strip 14 inserted into the first slot 13 is different, thereby adjusting the distance between the limit ring 15 and the third frame 8, thereby realizing the adjustment of the injection depth of the syringe body 32; The second through-holes 12 are arranged in three rows in an interlaced manner. When the position, angle and depth of the syringe body 32 are adjusted to the optimal state, the injection operation can be performed through the corresponding second through-holes 12; the first insert 14 is provided with a second slot 25 at the end close to the first handle 24, and a second insert 26 with a shape adapted thereto is inserted into the second slot 25; when the position, angle and depth of the syringe body 32 are adjusted to the optimal state, inserting the second insert 26 into the second slot 25 will cause the end of the first insert 14 close to the second insert 26 to expand and deform, thereby prompting the slider 7 to have a further expansion trend, and its outer wall will then squeeze the inner wall of the slide 6, so that the slider 7 is stably fixed at the injection positioning position in the slide 6; in addition, the end of the first insert 14 away from the limiting ring 15 is fixedly connected to the first handle 24, and the end of the second insert 26 away from the first insert 14 is fixedly connected to the second handle 27. The arrangement of the first handle 24 and the second handle 27 facilitates the operation of the first insert 14 and the second insert 26.
[0039] The working principle of the technical solution provided by the present invention is as follows: During use, the first and second frames 1, 2, clips 3, and Velcro 4 work together to achieve basic fixation. The staff quickly installs the first and second frames 1, 2, on the infant's upper arm near the deltoid muscle. Using the tightening tendency of the two during installation, the two clips 3 clamp around the infant's shoulders and head. The Velcro 4 is then inserted through the first perforations 5 and tightened, further enhancing the tightening effect of the first frame 1 and laying a stable foundation for subsequent injections.
[0040] To determine the injection location, two-dimensional or three-dimensional ultrasound is used to obtain parameters of the neonatal deltoid muscle. Two-dimensional ultrasound uses a high-frequency probe to obtain clear images, identifying the deltoid muscle edges and measuring its dimensions. Three-dimensional ultrasound scans and generates stereoscopic images, providing more comprehensive structural information and helping to accurately locate the optimal injection area. Next, the syringe body 32 is installed and adjusted. The syringe body 32 is inserted through the retaining ring 15 and into the retaining frame 17, positioning the needle within the retaining ring 15. The position of the syringe body 32 can then be flexibly adjusted by adjusting the position of the slider 7 to ensure optimal injection positioning. Pulling the fifth frame 21 deforms the first insert 14 and the fourth frame 20, causing the retaining ring 15 and the retaining frame 17 to change their angle. The retaining blocks 22 then engage the retaining grooves 23 at different locations on the third frame 8 to quickly adjust the syringe's injection angle and ensure accurate injection. The distance between the retaining ring 15 and the third frame 8 can then be adjusted by pulling the fifth frame 21 and the first insert 14 to adjust the injection depth. After the position, angle, and depth of the syringe are adjusted to the optimal state, the syringe body 32 is further pushed, allowing the syringe body 32 to perform the injection operation along the limiting frame 17 combined with the limiting buffer and guidance of the limiting ring 15, so that the needle of the syringe body 32 passes through the corresponding second perforation 12 for injection. At this time, the bending deformation of the third frame 8 and the third connecting strip 29 generates a restorative elastic force, allowing the pressing plate 9 and the auxiliary plate 10 to fit the infant's upper arm. The convex portion 11 on the pressing plate 9 reserves a gap, which neither affects the needle puncture nor helps to tighten the needle after puncture to prevent deviation. At the same time, it avoids direct contact between the medical staff's hands and the needle, reducing the risk of infection. During the insertion of the first insert 14 into the first slot 13, the buffer cavity 31 can undergo a certain expansion and deformation, making it easier for the first insert 14 to be inserted into the first slot 13, thereby quickly connecting the chute 6 and the syringe body 32. Simultaneously, as the buffer cavity 31 expands, the outer wall of the chute 6 squeezes the slider 7. Subsequently, the second insert 26 is inserted into the second slot 25 of the first insert 14, causing one end of the first insert 14 to expand, prompting the slider 7 to further expand and squeeze the inner wall of the chute 6, stably securing the slider 7 in the injection position. The provision of the first handle 24 and the second handle 27 facilitates operation and ensures a stable injection process. Throughout the entire process, the adjustment of position, angle, and depth, as well as the guiding and limiting effects of various components on the syringe body 32, ensure injection stability, significantly reducing discomfort felt by infants during BCG injection, while also improving operational safety and convenience.
[0041] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention.
