As shown in fig. 4, the arm support plate 1 is a semicircular arc plate which is concave downwards, a first groove 5 is formed in the arc surface of the front end of the arm support plate 1, the palm placing plate 3 is slidably arranged in the first groove 5, and the palm placing plate 3 is telescopically fixed in the arm support plate 1 through the sliding fixing structure 2. The arm supporting plate 1 is used for holding the arm of the patient, the wrist of the patient is arranged at the front end of the arm supporting plate 1, and the elbow of the patient is arranged at the rear end of the arm supporting plate 1. The palm rest plate 3 is used for placing the palm of the infant patient.

As shown in fig. 3 and 4, the sliding fixing structure 2 includes a fixing block 201 and a fixing hole 202, a plurality of fixing holes 202 are formed on the outer side surface of the arm support plate 1, the fixing holes 202 are arranged along the length direction of the arm support plate 1, and the fixing holes 202 are communicated with the first groove 5. The palm placing plate 3 is correspondingly provided with a fixing block 201, and the fixing block 201 is clamped in the fixing hole 202. Fixed block 201 is the elastic rubber material, and the accessible is pressed and is made fixed block 201 become flat state of flat to relieve the joint relation of fixed block 201 and fixed orifices 202, conveniently adjust the palm and place the length that board 3 stretched out. As shown in fig. 3, the fixing block 201 is released, and the fixing block 201 is engaged with the fixing hole 202, thereby fixing the palm rest plate 3 in the arm support plate 1.

The arm length of the infant patient with different heights is different, and the length of the palm placing plate 3 needs to be adjusted, so that the arm of the patient is completely placed on the fixing device. When adjusting the length that the board 3 was placed to the palm, press fixed block 201, simultaneously, the board 3 is placed to the tractive palm, makes the palm fixed plate slide in first recess 5 together with the fixed block 201 who is pressed. When the palm placing plate 3 is extended, the fixing blocks 201 are pressed, so that the palm placing plate 3 extends outwards along the arm supporting plate 1, the fixing blocks 201 on the palm placing plate 3 can be outwards clamped in the fixing holes 202 one by one, and the action of pressing the fixing blocks 201 is repeated until the extending length of the palm placing plate 3 meets the requirements of the sick child; shorten the palm and place board 3 time, press fixed block 201, make the palm place board 3 and retract to arm bearing board 1 in, the palm places fixed block 201 on the board 3 and can inwards joint one by one in fixed orifices 202, the action of repeated fixed block 201 of pressing, the length that 3 shortens of board is placed to the palm satisfies infant's demand.

As shown in fig. 1 and 2, the arm support plate 1 is provided with second grooves 6 on the upper rectangular surface, the sliding cover structure 4 is slidably disposed in the second grooves 6, the sliding cover structure 4 is a semicircular arc plate protruding upward, and the length of the sliding cover structure 4 is 1/2 of the arm support plate 1. A space for accommodating the arm of the patient child is formed between the sliding cover structure 4 and the arm supporting plate 1. The infant is inserted into the accommodation space, so that the arm of the infant is placed on the arm support plate 1, and the hand of the infant is placed on the palm placing plate 3. The position of the sliding cover structure 4 is adjusted according to the position of the infant needing puncturing, so that the sliding cover structure 4 is far away from the puncturing position, and the puncturing position is exposed. Meanwhile, the arms of the infant are constrained between the sliding cover structure 4 and the arm supporting plate 1, so that the positions of the arms of the infant are constrained, and the failure of puncture caused by the random shaking of the arms is avoided.

Because the accommodation space between the sliding closure structure 4 and the arm bearing plate 1 is slightly larger than the arm circumference of the infant, in order to avoid the arm of the infant to move in the accommodation space, the utility model discloses airbag structure 7 has been set up. As shown in fig. 1 and 4, the airbag structure 7 includes an inflatable cushion 701, an inflation tube 702, and an inflation bag 703, at least one inflatable cushion 701 is disposed on the inner side surface of the sliding cover structure 4, and the inflatable cushion 701 is communicated with the inflation bag 703 through the inflation tube 702. By pressing the inflating bag 703, gas enters the inflatable cushion 701 through the inflating tube 702, so that the inflatable cushion 701 is inflated and the arm of the infant patient is pressed, so that the arm of the infant patient is fixed in the arm support plate 1. When the patient needs to be detached, the air valve at the position of the air inflation tube 702 is opened, so that the air inflation pad 701 is restored to the flat state, the fixed relation is released, and the arm of the patient can be taken out from the arm supporting plate 1.

Before the infant patient punctures, the tourniquet needs to be tied on the arm. In order to facilitate the fastening of the tourniquet on the arm of the patient, as shown in fig. 1 and 4, a tourniquet groove 8 is provided on the inner side of the arm support plate 1. The two hemostatic grooves 8 are arranged along the radian direction of the arm supporting plate 1, and the two hemostatic grooves 8 are respectively arranged at the wrist part and the elbow part of the arm supporting plate 1. According to the puncture position of the patient, the tourniquet is tied on the wrist or the elbow, and the tourniquet enters the hemostasis groove 8 and is wound on the wrist or the elbow of the patient child.

As shown in fig. 1 and 4, the utility model further comprises a plurality of fixing bands 9, and the fixing bands 9 are respectively arranged on two sides of the palm placing plate 3 and two sides of the wrist part and the elbow part of the arm supporting plate 1. In order to further fix the arm of the patient child on the arm support plate 1, the palm rest plate 3 and the fixing bands 9 at both sides of the arm support plate 1 are respectively fastened to the hand, wrist or elbow of the patient child.

A sponge layer 10 is laid on the inner side of the arm bearing plate 1. The sponge layer 10 can adsorb sweat on the arms of the child patient, so that the arms of the child patient can keep dry and comfortable, and the comfort level of the child patient can be improved. And the sponge layer 10 is soft, so that the pressure sore on the arm of the child patient is avoided.

The sliding cover structure 4 is made of transparent silica gel, and the arm state of the infant patient can be observed through the transparent sliding cover structure 4. Meanwhile, the inflation condition of the inflatable cushion 701 on the inner side surface of the sliding cover structure 4 is observed, and when the inflatable cushion 701 is inflated to extrude and fix the arm of the infant, the pressing of the air bag 703 is stopped.

The utility model discloses use as follows:

the total length of the arm bearing plate 1 and the palm placing plate 3 is adjusted by the sliding fixing structure 2 according to the arm length of the infant patient. The infant extends into the containing space between the arm bearing plate 1 and the sliding closure structure 4, so that the arm of the infant is placed on the arm bearing plate 1, and the hand of the infant is placed on the palm placing plate 3. The position of the sliding cover structure 4 is adjusted according to the position of the infant needing puncturing, so that the sliding cover structure 4 is far away from the puncturing position, and the puncturing position is exposed. At the same time, the inflating bag 703 is pressed to inflate the inflatable cushion 701 and press the arm of the infant, so that the arm of the infant is fixed in the arm support plate 1. And the fixing belts 9 of all the parts are mutually bound on the palm, the wrist and the elbow of the infant patient. The tourniquet is tied at the wrist or elbow of the infant patient, and then the infant patient is subjected to venipuncture.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
