Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a medical fixator for pediatrics and a use method thereof. BACKGROUND

[0002] After birth, premature babies often need to be implanted with a venous catheter through the umbilical cord for necessary medical operations. In order to ensure the sterile environment during the operation, medical staff will lay sterile towels in the operation area.

[0003] In actual operation, premature babies often interfere with the operation due to their own involuntary movements, especially the movement of their legs. Medical staff usually use adhesive tape to paste the legs of premature babies on the bed surface to limit their movement range. Since the activity ability and strength of premature babies often exceed expectations, they can easily break free from the constraints of the adhesive tape, especially when they exert force. Once the adhesive tape is loose, the fixing effect of the sterile towel will be greatly reduced, and the sterile environment cannot be effectively guaranteed. Therefore, the present application provides a medical fixator for pediatrics and a use method thereof. SUMMARY

[0004] The present application aims to provide a medical fixator for pediatrics and a use method thereof to solve the problem of interference with the operation of premature babies due to their own involuntary movements, especially the movement of their legs, during actual operation. Medical staff usually use adhesive tape to paste the legs of premature babies on the bed surface to limit their movement range. Since the activity ability and strength of premature babies often exceed expectations, they can easily break free from the constraints of the adhesive tape, especially when they exert force. Once the adhesive tape is loose, the fixing effect of the sterile towel will be greatly reduced, and the sterile environment cannot be effectively guaranteed.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A medical fixator for pediatrics, comprising a fixing plate, wherein the fixing plate is symmetrically provided with an elongated hole, the upper end surface of the fixing plate is also symmetrically provided with a sliding groove, the upper end surface of the fixing plate is symmetrically provided with a linearly distributed limiting hole about the sliding groove, and the side of the fixing plate is respectively provided with a connecting jack; Self-adhesive elastic bandages are arranged in the elongated holes on both sides, a neck protection assembly is arranged on the upper end surface of the fixing plate, and a fixing assembly is detachably connected to the connecting jacks on both sides through a connecting rod.

[0006] Optionally, the neck protection assembly comprises a limiting plate, the limiting plate is openably and closably arranged on the upper surface of the fixing plate, nursing pillows are horizontally arranged between the inner sides of the limiting plate, and a pillow groove is arranged in the middle of the nursing pillows.

[0008] Optionally, the nursing pillow comprises, from bottom to top, a filling layer, a composite layer and a fitting layer, the upper surface of the filling layer being laminated with the composite layer, and the upper surface of the composite layer being sewn with the fitting layer.

[0009] Optionally, the composite layer is formed by interweaving a breathable layer and an antibacterial layer.

[0010] Optionally, the filling layer is made of high-density memory sponge.

[0011] Optionally, the fitting layer is made of skin-friendly cotton.

[0012] Optionally, the breathable layer is made of breathable mesh fabric, and the antibacterial layer is made of silver ion antibacterial fiber.

[0013] Optionally, the fixing assembly comprises a fixing member, the fixing member being detachably connected to the connecting socket through a connecting rod, a group of third gears, two groups of first gears and two groups of second gears being rotatably connected to the fixing member, the third gears being engaged with the two groups of second gears, the two groups of second gears being engaged with the two groups of first gears respectively, a driving motor being fixedly installed on the outer side of the fixing member, the output end of the driving motor being fixedly connected with the third gears, and a sliding tooth buckle being slidably connected in the fixing member, the sliding tooth buckle being engaged with the two groups of first gears.

[0014] A use method of a medical fixator for pediatrics, comprising: S1: first, sterilize the medical fixator and all components thereof completely to ensure a sterile environment, then connect the fixing assembly to the connecting socket through the connecting rod, and in the fixing member, drive the third gears to rotate through the output end of the driving motor, so that the sliding tooth buckle slides and blocks the gap on the fixing member, thereby fixing the fixing member and the rail of the nursing bed together to stabilize the fixing plate.

[0015] S2: then, according to the size of the premature infant, pre-adjust the position of the neck protection assembly on the fixing plate, fix the position of the neck protection assembly on the fixing plate through the movement of the sliding block in the sliding groove and the penetration of the limiting rod through the corresponding limiting hole, so as to adapt to the position of the nursing pillow of infants of different sizes and to make the position of the thigh of the infant in the position of the self-adhesive elastic bandage.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] The preferred embodiment of the device of the present invention will be described below.

[0023] Please see Figures 1-9 As shown, the pediatric medical fixation device includes a fixation plate 1, with elongated holes 101 symmetrically provided on the fixation plate 1, and sliding grooves 102 symmetrically provided on the upper end face of the fixation plate 1. Limiting holes 103 are linearly distributed symmetrically provided on the upper end face of the fixation plate 1 about the sliding grooves 102, and connecting insertion holes 104 are provided on the side of the fixation plate 1. Self-adhesive elastic bandages 2 are threaded through the elongated holes 101 on both sides. A neck protection component 3 is also provided on the upper end face of the fixing plate 1. The connecting holes 104 on both sides are detachably connected to the fixing component 4 via the connecting rod.

[0024] In another embodiment provided by the present invention, such as Figure 1 , 2 As shown in Figures 7 and 9, the neck protection component 3 includes a limiting plate 301, which is openable and closable on the upper surface of the fixing plate 1. A nursing pad 302 is horizontally arranged between the inner side plates of the limiting plate 301, and a pillow groove 303 is provided in the middle of the nursing pad 302.

[0025] Furthermore, the neck protection component 3 also includes an adjustment plate 304 fixedly connected to the limiting plate 301. The bottom of the adjustment plate 304 is provided with a sliding block 305 that cooperates with the sliding groove 102. The bottom of the back side of the adjustment plate 304 away from the nursing pad 302 is provided with a limiting block 306. A limiting rod 307 that cooperates with the limiting hole 103 is provided through the limiting block 306.

[0026] Specifically, based on the size of the newborn infant, to ensure that the infant's thighs can be accurately placed in the position of the self-adhesive elastic bandage 2, the position of the neck protection component 3 is adjusted. The sliding adjustment plate 304 drives the limiting plate 301 and the nursing pad 302 to slide. The sliding block 305 slides in the sliding groove 102 to the appropriate position. Then, the knob limiting rod 307 is turned into the limiting hole 103, thereby firmly fixing the limiting block 306 to the fixing plate. The fixing of the limiting block 306 thus fixes the position of the entire neck protection component 3.

[0027] Furthermore, the nursing pillow 302 includes, from bottom to top, a filling layer 3021, a composite layer 3022, and an adhesive layer 3023. The composite layer 3022 is laminated on the upper surface of the filling layer 3021, and the adhesive layer 3023 is sewn onto the upper surface of the composite layer 3022.

[0028] Furthermore, the composite layer 3022 is formed by interlacing the breathable layer 3024 and the antibacterial layer 3025.

[0029] Furthermore, the filling layer 3021 is made of high-density memory foam. High-density memory foam can conform well to the curve of the neck, providing even and soft support. The neck muscles and bones of newborns are not yet fully developed, so a surface that can provide stable support without causing pressure is needed. The slow rebound characteristics of high-density memory foam can well meet this need. The bonding layer 3023 is made of skin-friendly cotton. The healthy, environmentally friendly and soft properties of skin-friendly cotton make it an ideal choice for the newborn care pillow 302. Newborns' skin is very sensitive and easily affected by irritation and friction. The skin-friendly cotton material reduces friction with the skin, providing a comfortable feel. The breathable layer 3024 is made of breathable mesh fabric. Newborns have relatively weak thermoregulation capabilities and are easily affected by ambient temperature. The porous structure of the breathable mesh fabric allows air to flow freely, keeping the neck area cool and comfortable. The antibacterial layer 3025 is made of silver ion antibacterial fibers. Incorporating silver ion antibacterial fibers into the nursing pillow 302 can significantly reduce the risk of bacterial growth, keep the pillow clean and hygienic, and destroy the cell walls and DNA of bacteria, effectively inhibiting bacterial growth and reproduction.

[0030] In another embodiment provided by the present invention, such as Figure 8As shown, the fixing component 4 includes a fixing member 401, which is detachably connected to the connecting socket 104 via a connecting rod. A set of third gears 404, two sets of first gears 402, and two sets of second gears 403 are rotatably connected to the fixing member 401. The third gears 404 mesh with the two sets of second gears 403, and the two sets of second gears 403 mesh with the two sets of first gears 402 respectively. A drive motor 405 is fixedly installed on the outside of the fixing member 401, and the output end of the drive motor 405 is fixedly connected to the third gears 404. A sliding toothed buckle 406 is slidably connected inside the fixing member 401, and the sliding toothed buckle 406 meshes with both sets of first gears 402.

[0031] Specifically, inside the fixing member 401, the output end of the drive motor 405 drives the third gear 404 to rotate, causing the sliding tooth buckle 406 to slide. The sliding tooth buckle 406 then blocks the notch on the fixing member 401, thus fixing the fixing member 401 to the railing of the nursing bed, thereby stabilizing the fixing plate 1.

[0032] A method of using a pediatric medical fixation device: S1: First, thoroughly disinfect the medical fixation device and all its components to ensure a sterile environment. Then, connect the fixation component 4 to the connection socket 104 via the connecting rod. Inside the fixation component 401, the output end of the drive motor 405 drives the third gear 404 to rotate, causing the sliding tooth buckle 406 to slide. The sliding tooth buckle 406 then blocks the notch on the fixation component 401, thus fixing the fixation component 401 to the railing of the nursing bed, thereby stabilizing the fixation plate 1.

[0033] S2: Then, according to the size of the premature infant, the position of the neck protection component 3 on the fixing plate 1 is adjusted in advance. It is fixed by the movement of the sliding block 305 in the sliding groove 102 and the limit rod 307 passing through the corresponding limit hole 103, so as to adapt to the position of the nursing pillow 302 for infants of different sizes and to make the infant's thigh position the position of the self-adhesive elastic bandage 2.

[0034] S3: Then, according to the position of the baby's thigh, wrap the self-adhesive elastic bandage 2 around the side of the baby's thigh and stick it firmly. Adjust the tightness of the self-adhesive elastic bandage 2 as needed to ensure the best fixation effect. The self-adhesive elastic bandage 2 is for single use, and it is easy to replace another self-adhesive elastic bandage 2 through the elongated hole 101.
