[0002] Infusion has become a common way of administering medicine in the treatment of children's diseases. The characteristics of preschool children make infusion difficult. Not only does it require nurses to have high clinical experience, puncture techniques and psychological qualities, but it also requires humanistic care for children in the entire infusion process, integrating psychological and mental care with disease prevention and treatment. Because children are active and prone to needle slippage or even puncture of blood vessels, leading to infusion failure, nurses often put the injection packaging box under the children's hands and then wrap it with tape to prevent such things from happening.

[0003] In the prior art, there is an adjustable pediatric infusion fixing plate disclosed in application number: CN103948994A, which includes a plate surface and a fixing belt. The plate surface is a rectangular hard plate with two rows of rectangular through holes on both sides. The fixing belt is an elastic belt with a width of 20 mm. The front side of one end of the fixing belt is provided with a nylon hook belt with a width of 16 mm and a length of 50 mm, and the back side of the other end is provided with a nylon velvet belt with a width of 16 mm and a length of 50 mm. The two ends of the fixing belt with the hook belt and the velvet belt are respectively inserted into the two rectangular through holes on both sides of the back side of the plate surface and then pulled out from the front.

At the same time, when the child still feels that his hands are cold, the heating mechanism 10 can be controlled to operate. The heating mechanism 10 will heat the liquid medicine inside the infusion tube to a certain extent, thereby preventing the child's hands from being cold. At the same time, the temperature can also be transmitted to the inside through the through groove 3, thereby improving the comfort of the child during infusion. When the child puts his hand into the outer protective shell 1, the auxiliary mechanism 12 can drive the adjustment mechanism 11 to approach each other, thereby restraining and fixing the child's wrist, thereby preventing the child from moving around during the infusion process and preventing the needle from being misplaced, thereby reducing the child's pain and effectively reducing the difficulty of the work of medical staff. At the same time, the auxiliary mechanism 12 can prevent the child from accidentally touching the adjustment mechanism 11 and causing it to loosen, thereby improving the practicality of the equipment.

[0033] like Figure 2-4As shown, the heating mechanism 10 includes a rotating wheel 1001, a bevel gear 1002, a bevel gear 1003, a rotating rod 1004, a movable plate 1005, a heat-resistant fixed plate 1006 and a heating wire 1007.

[0034] After the infusion tube passes through the installation shell 4 and the through groove 3, the medical staff can give the child an injection. When the medical staff has fixed the infusion tube, they can help the child put his hand into the outer protective shell 1, and then the rotating wheel 1001 can be rotated. When the rotating wheel 1001 rotates, it will drive the bevel gear 1002 to rotate, and the bevel gear 2 1003 will also rotate accordingly. At this time, the rotating rod 1004 will drive the moving plates 1005 to move closer to each other, thereby driving the heat-resistant fixing plates 1006 to move closer to each other, so as to clamp and fix the infusion tube inside the groove to a certain extent, thereby preventing the infusion tube from being offset when the child shakes, thereby pulling In the event of pulling the needle, if the child feels cold hands during the infusion process, the USB connecting line 9 can be plugged into the mobile power supply 6, and the heating wire 1007 will be heated to a certain extent. At this time, the heat-resistant fixing plate 1006 will prevent the heating wire 1007 from causing damage to the infusion tube. The heat generated by the heating wire 1007 will heat the liquid inside the infusion tube to a certain extent through the heat dissipation holes, and the heat can also be transferred to the inside of the outer protective shell 1 through the through groove 3, thereby ensuring the temperature of the child's hands. In addition, the heating mechanism 10 can improve the comfort of the child during infusion, and at the same time ensure the safety of the child during infusion.

[0035] like Figure 5-7As shown, the auxiliary mechanism 12 includes a fixed top plate 1201, an adjustment handle 1202, a transmission rod 1203, a screw 1204, a fixed block 1205, an elliptical cam 1206, a connecting rod 1207 and a return spring 1208. The bottom end of the adjustment handle 1202 is fixedly connected to the top of the transmission rod 1203, the bottom end of the transmission rod 1203 is fixedly connected to the inside of the elliptical cam 1206, the screw 1204 is threadedly connected to the inside of the transmission rod 1203, the fixed block 1205 is fixedly connected to the bottom end of the inside of the fixed top plate 1201, and the internal opening of the fixed block 1205 A card slot is provided, and two connecting rods 1207 are symmetrically arranged on the left and right sides and front and back, and the top end of the connecting rod 1207 is hinged to the bottom end of the screw rod 1204, and the bottom end of the connecting rod 1207 is movably connected to the inside of the card slot, and a reset spring 1208 is fixedly connected to the opposite side of the bottom end of the connecting rod 1207, and a pressing rod is hinged inside the top end of the screw rod 1204, and the bottom end of the fixed top plate 1201 is fixedly connected to the top end of the connecting shell 7, and the bottom end of the screw rod 1204 extends to the outside of the bottom end of the elliptical cam 1206, and the elliptical cam 1206 is rotatably connected to the inside of the fixed top plate 1201.

[0036] After the personnel adjustment is completed, the pressing rod can be rotated. When the pressing rod is rotated, the screw 1204 will be driven to rotate. At this time, the screw 1204 will drop accordingly. At this time, the bottom end of the screw 1204 will be inserted into the fixed block 1205. As the screw 1204 drops, the two sides of the bottom end of the connecting rod 1207 will expand to both sides under the action of pressure, so that it can be horizontally connected to the inside of the slot. At this time, the transmission rod 1203 cannot rotate either, thereby achieving the role of limiting, preventing children from accidentally touching it during play, causing the adjustment mechanism 11 to loosen, thereby reducing the inconvenience of medical staff and effectively improving the practicality of the equipment.

[0037] like Figure 3-6As shown, the adjustment mechanism 11 includes a telescopic rod 1101, a vertical guide rod 1102, a parallel slider 1103, a folding rod 1104, a second return spring 1105, a third return spring 1106, an adjustment plate 1107 and a rubber pad 1108. One end of the telescopic rod 1101 is fixedly connected to the top of the vertical guide rod 1102, the bottom end of the vertical guide rod 1102 is fixedly connected to the top of the parallel slider 1103, the parallel slider 1103 is provided with two front and rear symmetrical sliders, and both ends of the folding rod 1104 are hinged to the outer wall of the parallel slider 1103, the middle section of the folding rod 1104 is hinged to the outer wall of the adjustment plate 1107, and the rubber pad 1108 is fixedly connected to the outer wall of the adjustment plate 1107. The rubber pad 1108 is fixedly connected to the inner wall of the adjusting plate 1107, and the return spring 1105 is fixedly connected to the opposite side of the parallel slider 1103, wherein one of the parallel sliders 1103 is fixedly connected to the inside of the connecting shell 7, and the other parallel slider 1103 is slidably connected to the inside of the connecting shell 7. The other end of the telescopic rod 1101 is hinged to one side of the bottom end of the elliptical cam 1206, and the telescopic rod 1101 is rotatably connected to the top of the connecting shell 7 through a bearing. One end of the return spring 1106 is fixedly connected to the inner wall of the connecting shell 7, and the other end of the return spring 1106 is fixedly connected to the outer wall of the splint, and the front side of the rubber pad 1108 is fixedly connected to the inner wall of the telescopic plate 8.

[0038] When the child inserts the hand into the outer protective shell 1, the child can rotate the adjusting handle 1202, thereby driving the elliptical cam 1206 to rotate through the transmission rod 1203 below. When the elliptical cam 1206 rotates, it will drive the telescopic rod 1101 to move, thereby driving the parallel slider 1103 on one side to move, and the folding rod 1104 will also fold accordingly. During the folding process, the adjusting plates 1107 will be driven to approach each other, so that the medical staff can adjust the distance between the rubber pads 1108 according to the size of the child's wrist, thereby restraining and fixing the child's wrist to prevent the child's hand from shaking during the infusion process, which may cause the needle to be misplaced. At the same time, this device can be adapted to children of different wrist thicknesses, thereby improving the practicality of the equipment. At the same time, the rubber pad 1108 can also improve the comfort of the child's wrist.

[0039] Here's how it works.

[0040] When in use, after the infusion tube passes through the installation shell 4 and the through groove 3, the medical staff can give the child an injection. After the medical staff has fixed the infusion tube, they can help the child put his hand into the outer protective shell 1, and then the rotating wheel 1001 can be rotated. When the rotating wheel 1001 rotates, it will drive the bevel gear 1002 to rotate, and the bevel gear 2 1003 will also rotate accordingly. At this time, the rotating rod 1004 will drive the moving plates 1005 to move closer to each other, thereby driving the heat-resistant fixing plates 1006 to move closer to each other, so as to clamp and fix the infusion tube inside the groove to a certain extent, thereby The infusion tube is prevented from being offset when children shake, thereby pulling the needle. At the same time, during the infusion process, if the child feels cold hands, the USB connection cable 9 can be plugged into the mobile power supply 6. At this time, the heating wire 1007 will be heated to a certain extent. At this time, under the action of the heat-resistant fixing plate 1006, the heating wire 1007 will be prevented from causing damage to the infusion tube. The heat generated by the heating wire 1007 will heat the liquid medicine inside the infusion tube to a certain extent through the heat dissipation holes. At the same time, the heat can also be transferred to the inside of the outer protective shell 1 through the through groove 3, thereby ensuring the temperature of the child's hands.

[0041] When the child inserts the hand into the outer protective shell 1, the child can rotate the adjusting handle 1202, thereby driving the elliptical cam 1206 to rotate through the transmission rod 1203 below. When the elliptical cam 1206 rotates, it will drive the telescopic rod 1101 to move, thereby driving the parallel slider 1103 on one side to move, and the folding rod 1104 will also fold accordingly. During the folding process, the adjusting plates 1107 will be driven to move closer to each other, so that the medical staff can adjust the distance between the rubber pads 1108 according to the size of the child's wrist, thereby restraining and fixing the child's wrist to prevent the child's hand from shaking during the infusion process, which may cause the needle to be misplaced. At the same time, this device can be adapted to children with different wrist thicknesses, thereby improving the practicality of the equipment. After the personnel adjustment is completed, the pressing rod can be rotated. When the pressing rod is rotated, the screw 1204 will be driven to rotate. At this time, the screw 1204 will drop accordingly. At this time, the bottom end of the screw 1204 will be inserted into the interior of the fixed block 1205. As the screw 1204 drops, the two sides of the bottom end of the connecting rod 1207 will expand to both sides under the action of pressure, so that it is laterally clamped in the interior of the card slot. At this time, the transmission rod 1203 is also unable to rotate, thereby achieving the role of limiting, preventing children from accidentally touching it during play, causing the adjustment mechanism 11 to loosen.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
