Description
Technical Field
[0001] The utility model relates to the technical field of children's foot fixing, in particular to a children's foot fixing device. Background Art
[0002] Infusion is also known as drip or hanging water. It is an injection that is injected into the body by intravenous drip. It is usually packaged in glass or plastic infusion bottles or bags, without preservatives or antibacterial agents. When used, the drip rate is adjusted through the infusion device, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. Pediatric infusion is often performed by venous puncture on the child's feet or head to achieve the purpose of intravenous infusion for children.
[0003] The prior art does not have a structure for fixing the feet of different children of different sizes when in use, so that when performing puncture or infusion on the feet of children aged 0-1, the children's feet are easily moved around, causing the needle to roll, affecting the retention time of the infusion needle. If a foot fixer is used for fixation, since children aged 0-1 grow faster, the foot sizes of children of different months or different physiques are different, and a single-size foot fixer cannot meet the needs of different people. Based on the shortcomings of the prior art, the utility model designs a child foot fixing device. Utility Model Content

[0015] The child foot fixing device places the foot on the upper surface of a fixing bottom plate and pushes it backwards, so that the ankle is closely attached to the inner side of the ankle support. Then loosen the nut counterclockwise to release the clamping and locking of the side panels. At this time, push the two side panels inward at the same time so that the inner sides of the side panels are tightly clamped against the sides of the ankles. After the rotation angle of the side panels can achieve clamping and fixing of the feet, tighten the nut clockwise to use the threaded joint and the limit rod to re-lock the side panels. At this time, open the connecting buckle to disconnect the elastic strap, and then place the sole of the foot on the upper surface of the slide seat, and then rotate the rotating head clockwise or counterclockwise to drive the threaded rod to rotate. The rotating threaded rod uses the threaded through hole to control the slide seat to move left or right and drive the elastic strap to move accordingly to adjust the fixed point. After the position of the elastic strap is adjusted, the two sections of elastic straps are passed around the top of the foot and connected with the connecting buckle to clamp the foot.

[0029] Working principle: when a child foot fixing device is used, in the initial state, first, the ankle support 101 is set on the upper surface of the fixed bottom plate 1, and the side plates 104 are rotatably connected in the rotation grooves 102 opened on both sides of the ankle support 101. The rotating rods 105 set on the side plates 104 are rotatably inserted into the inside of the rotating holes 103 to fix the child's ankles. The bottom end of the limiting rod 201 fixedly connected to the bottom of the side plates 104 is connected to a threaded joint 202, and the limiting rod 201 and the threaded joint 202 penetrate and slide. Inserted in the limiting arc groove 2 which is provided through the fixed bottom plate 1, and the threaded joint 202 is also connected with the nut 203, so as to control the rotation and expansion of the side plate 104, so as to wrap and fix the ankles of children of different sizes. At the same time, a slide seat 304 and a pad 306 which are controlled by the threaded rod 302 are slidably connected in the slide groove 301 provided on the upper surface of the front end of the fixed bottom plate 1, and two sections of elastic straps 307 fixed on the slide seat 304 are connected by a connecting buckle 308, so as to fix the feet of different lengths.
[0030] When it is necessary to fix the feet of children of different sizes, first place the feet on the upper surface of the fixed base plate 1 and push backwards so that the ankles are tightly attached to the inner side of the ankle support 101. Then loosen the nut 203 counterclockwise to release the clamping and locking of the side plates 104. At this time, push the two side plates 104 inward at the same time so that the inner sides of the side plates 104 are tightly clamped against the sides of the ankles. After the side plates 104 rotate to an angle that can clamp and fix the feet, tighten the nut 203 clockwise to re-lock the side plates 104 using the threaded joint 202 and the limit rod 201. At this time, open the connecting buckle 308 to disconnect the elastic bandage 307, then place the sole of the foot on the upper surface of the slide seat 304, and then rotate clockwise or counterclockwise. The rotating head 303 drives the threaded rod 302 to rotate, and the rotating threaded rod 302 uses the threaded through hole 305 to control the slide seat 304 to move left or right and drive the elastic strap 307 to move and adjust the fixed point. After the position adjustment of the elastic strap 307 is completed, the two sections of the elastic strap 307 are passed over the top of the foot and connected with the connecting buckle 308 to clamp the foot. If the child is resistant or the weather is cold, the Velcro 309 can be used to stick interesting embroidery pieces or warm outer layers. This device is convenient for fixing the feet of children of different sizes.
