Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a neonatal heel blood sampling auxiliary device. Background Art

[0002] Neonatal blood draws are typically done from the heel, back of the hand, or scalp, depending on the purpose of blood collection, ease of use, and the neonate's condition. Heel prick is a common choice, often used for neonatal disease screening due to its rich blood vessels and relatively low pain sensitivity. Veins in the back of the hand or wrist are suitable for tests requiring larger blood volumes. In special circumstances, scalp veins or elbow veins may be used.

[0003] Currently, when a single person draws blood from a heel, they need to hold the heel with one hand and draw blood with the other hand, which is not easy to operate. In addition, the newborn will move around during the blood draw, and the needle may easily pierce the wrong spot, making blood collection inconvenient. In addition, the hand holding the heel needs to squeeze the heel during blood draw, increasing the amount of bleeding for blood collection, which is inconvenient to operate. Summary of the Invention

By tightening the locking bolt, the plug plate is restricted from sliding out of the fixing sleeve; a number of restraint belts 6 are provided on the connecting sleeve and the rotating plate 5;

[0025] In this embodiment, telescopic columns 3 are slidingly provided on both sides of the front end of the base 1, and a rotating plate 5 is rotatably installed on the protruding end of the telescopic column 3, and a fixer 7 is rotatably installed on the rotating plate 5; when in use, the newborn is placed on the base 1, the calf is placed on the rotating plate 5, the calf is fixed by the restraint belt 6, and the sole of the foot is fixed on the fixing plate 71 by rotating the pressure plate 72, thereby limiting the movement of the newborn's foot, avoiding the newborn's foot movement affecting the operation, and there is no need to hold the foot with hands, freeing both hands; and the pump body 2 can pressurize the airbag 73 to squeeze the foot to bleed or deflate the foot to return blood, without pinching the foot to increase bleeding, which facilitates blood collection operation.

[0026] Example 2:

[0027] In this embodiment, according to embodiment 1, the hand holding the heel needs to squeeze the heel during blood collection, which increases the amount of bleeding for blood collection, and the operation is inconvenient; therefore, a device is needed to replace manual squeezing;

[0028] In this embodiment, an airbag 73 is provided on the fixing plate 71 and the pressure plate 72. A pump body 2 is fixedly provided on one side of the base 1. The pump body 2 and the airbag 73 are connected by an air pipe. The airbag 73 is inflated by the pump body 2 to control the expansion of the airbag 73.
