Description

Technical Field

[0001] The utility model relates to the technical field of children's blood collection, and particularly relates to an auxiliary restriction device for children's blood collection. Background Art

[0002] Children's blood collection is usually for body fluid cell blood examination, including blood routine, biochemical examination, coagulation function determination, immunological examination and thyroid function examination. Before blood collection, strenuous exercise should be avoided to prevent affecting the distribution of blood components and interfering with the accuracy of the results. After blood collection, a cotton swab should be used to press the puncture site with moderate force to avoid congestion or bleeding caused by excessive pressure. Keep the puncture site clean and dry to avoid infection.

[0003] Currently, when collecting blood from children, due to their young age, children usually show fear, crying or resistance behaviors because of fear of blood collection, which increases the difficulty of blood collection. And during blood collection, in order to make the blood vessels full so that medical staff can more accurately find and puncture the blood vessels, children are required to clench their fists or a rubber tourniquet is tied around the wrist to temporarily block blood return. However, considering the fear and resistance of most children towards blood collection, it is usually difficult to make children clench their fists by themselves, and tying a tourniquet around the wrist further increases the discomfort of children and their resistance, thus further increasing the difficulty of blood collection.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] The present utility model provides an auxiliary restraint device for child blood collection as shown in Figure 1-2 which includes a bottom plate 1. A clamp 4 for fixing the bottom plate 1 on the tabletop is fixed to the bottom of the bottom plate 1. The arm of the child to be blood collected is placed on the bottom plate 1, and a fixing portion for fixing the child's arm is provided on the top of the bottom plate 1;

[0035] Specifically, as shown in Figure 3-5As shown in the figure, the fixing component 2 includes a restraint strap 21. An airbag 22 is fixed to the inner wall of the restraint strap 21. Two airbag tubes 29 are fixedly connected to the outside of the airbag 22. The airbag tubes 29 penetrate through the restraint strap 21, and a tube plug is provided on each airbag tube 29. Open the tube plug on one airbag tube 29, then connect this airbag tube 29 to an air pump or a balloon. Place the child's arm inside the restraint strap 21, and then wrap the restraint strap 21 around the outside of the child's arm (forearm). The two ends of the restraint strap 21 are fixed by Velcro to restrict the child's arm and reduce the difficulty of blood collection. At this time, the airbag 22 also surrounds the child's arm. Then, the air pump is powered on or the balloon is squeezed to input air into the airbag 22 to make the airbag 22 expand and press on the child's arm to make the blood vessels dilate, facilitating the puncture of the blood vessels by the operator and reducing the difficulty of blood collection.

[0036] Moreover, a mounting plate 23 is fixed to the bottom of the restraint strap 21, and a slider 24 is fixed to the bottom of the mounting plate 23. A chute 11 is formed on the top end of the bottom plate 1 on the side away from the shielding component 3. The slider 24 is slidably arranged in the chute 11 to facilitate the adjustment of the position of the fixing component 2. A groove 12 communicating with the chute 11 is formed on one side of the bottom plate 1. A screw rod 25 is fixed to the outside of the slider 24. After the slider 24 is inserted into the chute 11, the screw rod 25 is arranged in the groove 12 and extends out of one side of the bottom plate 1. A nut 26 is threadedly connected to the end of the screw rod 25 extending out of the bottom plate 1 for fixing the fixing component 2 and the bottom plate 1.

[0037] Insert the slider 24 into the chute 11, and the slider 24 can slide along the chute 11, facilitating the adjustment of the position of the fixing part on the bottom plate 1 and being suitable for use by different children. At the same time, since the arm lengths of children of different ages are different, an appropriate number of fixing components 2 can be selected and installed on the bottom plate 1. Since insertion blocks 28 are respectively fixed at both ends of the mounting plate 23 and slots 27 are formed, and the slots 27 are adapted to the insertion blocks 28, when there are two or more groups of fixing components 2, the insertion blocks 28 on the mounting plate 23 are inserted into the slots 27 of its adjacent mounting plate 23 to facilitate the assembly of two or more groups of fixing components 2. At this time, the adjacent two airbag tubes 29 are connected by a pipeline to facilitate the connection of the adjacent two airbags 22.

[0038] Then open the tube plug on one airbag tube 29, and then connect this airbag tube 29 to an air pump or a balloon to simultaneously inflate multiple airbags 22 for fixing the child's arm. Therefore, the utility model is convenient for adjusting the length of the fixing part to fix the arms of children of different ages for blood collection, thereby expanding the scope of application.

[0039] As Figure 1-2 shown, a shielding component 3 is also provided outside the bottom plate 1 for shielding the child's sight, as Figure 6As shown in the figure, the shielding assembly 3 includes a hollow plate 31. One side of the bottom of the hollow plate 31 is provided with an opening 32 through which a child's arm can pass. The bottom plate 1 passes through the opening 32. An extension plate 33 is slidably arranged inside the hollow plate 31, and the extension plate 33 is arranged at the top of the opening 32. The hollow plate 31 and the extension plate 33 are fixed by a first locking bolt 34, which is convenient for the extension and contraction of the shielding assembly 3. During blood collection, the child faces the shielding assembly 3, puts the arm on the bottom plate 1 through the opening 32, and shields the child's line of sight by adjusting the height of the shielding assembly 3 to prevent the child from seeing the blood collection needle behind the shielding assembly 3, reducing the child's fear and resistance psychology, which is beneficial to reducing the difficulty of blood collection.

[0040] Furthermore, sliding rods 13 are fixedly arranged on both sides of one end of the bottom plate 1 close to the shielding assembly 3, and both sliding rods 13 pass through the bottom of the hollow plate 31. The hollow plate 31 is slidably connected to the sliding rods 13, and a second locking bolt 35 for fixing the hollow plate 31 and the sliding rods 13 is threadedly connected to one side of the hollow plate 31. After sliding the hollow plate 31 along the sliding rods 13, tighten it with the second locking bolt 35, which is convenient for adjusting the position of the shielding assembly 3 on the bottom plate 1, suitable for different children to use, and expanding the scope of application.
