[0029] As Figures 1 - 5 shown, an embodiment of the present invention provides a fixed structure for platelet collection, including a base plate 1 and a blood collection pad 2 fixed on the base plate 1, and further including:

[0030] Slider 8, a suction cup 3 is fixed to the bottom of the bottom plate 1, a through groove 7 is provided on the blood collection pad 2, inverted L-shaped plates 10 are fixed to opposite sides of the inner wall of the through groove 7, a slider 8 is slidably connected between the two inverted L-shaped plates 10, the bottom of the slider 8 is slidably connected to the top of the bottom plate 1, the inverted L-shaped plates 10 provide guidance for the movement of the slider 8 and prevent the slider 8 from moving upward. A square plate 13 is fixed to the slider 8, the bottom of the square plate 13 is slidably connected to the top of the inverted L-shaped plate 10, a soft pad block 12 is fixed to the square plate 13, the soft pad block 12 is composed of a sponge block and a leather layer wrapped around the sponge block, and the soft pad block 12 is used to prevent the square plate 13 from being uncomfortable to people. A clamping member 9 is arranged inside the slider 8, a clamping groove 11 is provided on the side of the inverted L-shaped plate 10, and the end of the clamping member 9 is stuck in the clamping groove 11. A magic male sticker 5 and a magic female sticker 4 are respectively fixed on the blood collection pad 2, and a magic male sticker 6 is fixed on the soft pad block 12. The above components form a fixing structure to realize the restraint of the child's forearm, effectively prevent the position of the blood collection needle from changing, and thus prevent the occurrence of inaccurate blood vessel puncture or damage to the surrounding tissues.

[0031] As Figure 1 shown, in this embodiment, the ends of the magic male sticker 5 and the magic male sticker 6 away from the magic female sticker 4 are both provided with winding parts, and the thickness of the winding parts is greater than the thickness of the magic male sticker 5 itself and the thickness of the magic male sticker 6 itself. Pinching the position of the winding part facilitates the separation of the magic male sticker 5 or the magic male sticker 6 from the magic female sticker 4.

[0032] As Figure 3 、 Figure 4 and Figure 5 shown, in this embodiment, the clamping member 9 includes a cavity 92 opened inside the slider 8, two clamping pins 91 are slidably connected in the cavity 92, the ends of the clamping pins 91 movably penetrate through the slider 8 and are in contact with the inner wall of the clamping groove 11, a spring piece 93 is arranged inside the cavity 92, and the opposite ends of the two clamping pins 91 are respectively fixed to both ends of the spring piece 93. The clamping pins 91 are stuck in the corresponding clamping grooves 11 under the elastic force of the spring piece 93, so as to realize the positioning of the slider 8.

[0033] As Figure 5 shown, in this embodiment, a limiting ring 94 is fixedly sleeved at the end of the clamping pin 91, and the side of the limiting ring 94 is in contact with the side of the inner wall of the cavity 92. The limiting ring 94 is used to keep the distances of the two clamping pins 91 moving outwards from the cavity 92 consistent and ensure the smooth movement of the clamping pins 91.

[0034] As Figure 5 shown, in this embodiment, a rubber strip 95 is fixed to the bottom of the inner wall of the cavity 92, the top of the rubber strip 95 is fixed to the bottom of the spring piece 93, and the pulling force of the rubber strip 95 is used to assist the spring piece 93 to rebound to the initial state as shown in Figure 5 shown, so as to ensure the smooth operation of the spring piece 93.

[0035] As Figure 5 shown, in this embodiment, connection pieces 96 are fixedly sleeved on both the top and bottom of the rubber strip 95. The two connection pieces 96 are respectively fixed to the bottom of the inner wall of the cavity 92 and the bottom of the elastic piece 93. The connection pieces 96 are used to increase the contact area between the rubber strip 95 and the bottom of the inner wall of the cavity 92 and the elastic piece 93, thereby improving the connection strength between the rubber strip 95 and the bottom of the inner wall of the cavity 92 and the elastic piece 93.

[0036] As Figure 4 shown, in this embodiment, the end of the latch 91 away from the elastic piece 93 is hemispherical, and the inner wall of the card slot 11 is a curved surface to prevent the latch 91 from getting stuck in the card slot 11 and unable to move.

[0037] As Figure 4 shown, in this embodiment, the two latches 91 are symmetrically arranged with the central vertical plane passing through the slider 8 as the symmetry plane. The two latches 91 jointly position the slider 8, making the positioning of the slider 8 more stable and reliable.

[0038] Working principle: Place the child's forearm on the blood collection pad 2. The suction cup 3 at the bottom of the bottom plate 1 adsorbs on a plane to realize the positioning of the blood collection pad 2. Then, pass the first magic male tape 5 around the wrist from above and paste it on the magic female tape 4. The position of the child's wrist is restricted by the cooperation of the first magic male tape 5 and the magic female tape 4. Pass the second magic male tape 6 around the forearm from above and paste it on the magic female tape 4. The child's forearm is restricted by the cooperation of the second magic male tape 6 and the magic female tape 4. When collecting blood from the child, the child's forearm can be restricted, effectively preventing the position of the blood collection needle from changing, thereby preventing the occurrence of inaccurate blood vessel puncture or damage to the surrounding tissues;

[0039] Move the slider 8. The slider 8 drives the latch 91 to move. The curved surface of the inner wall of the card slot 11 squeezes the curved surface of the end of the latch 91, causing the latch 91 to move into the cavity 92 and squeeze the elastic piece 93. While the elastic piece 93 bends upward and deforms, it pulls the rubber strip 95 into a stretched state. After moving the slider 8 to a suitable position, the latch 91 corresponds to the corresponding card slot 11 at this time. The elastic piece 93 returns to its initial state under the action of its own elastic force and the pulling force of the rubber strip 95, thereby driving the latch 91 to fit the inner wall of the corresponding card slot 11 at this time, locking the slider 8, and thus realizing the positioning after the position adjustment of the slider 8. The position of the slider 8 is adjustable to adapt to forearms of different lengths;

[0040] After the platelet collection is completed, separate the second magic male tape 6 and the first magic male tape 5 from the magic female tape 4. After separation, the child can remove his / her own forearm from the blood collection pad 2.

[0041] The present utility model covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the present utility model. For the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.

[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
