AI Technical Summary
Existing neonatal hemostasis devices are prone to obstructing blood circulation during use, posing safety risks.
A neonatal hemostasis device was designed, comprising a binding strip, a rotating seat, a rotating plate, and a hemostasis structure. The binding strip uses a flexible metal core and an adhesive layer, and achieves open fixation through a ratchet and pawl mechanism. Combined with the pressure adjustment of the rotating plate, it provides continuous pressure and hemostasis.
It avoids blood circulation obstruction, improves safety, ensures unimpeded blood circulation in newborns, and allows for flexible adjustment of pressure to quickly and effectively stop bleeding.

Abstract
Claims
1. A neonatal hemostasis device, characterized in that, include: Binding strips are used to wrap around the limbs or torso of newborns; The rotating seat is connected to the binding strip; A rotating plate is hinged to the rotating seat; A hemostatic structure is provided on the rotating plate; The rotating seat has a ratchet on the side facing the rotating plate; the rotating plate has a pawl on the side facing the rotating seat; when the rotating plate rotates toward the direction close to the binding strip, the ratchet rotates freely; when the rotating plate rotates away from the binding strip, the pawl engages with the ratchet.
2. The neonate hemostasis device of claim 1, wherein, The binding strip includes a flexible metal core and an adhesive layer covering the metal core.
3. The neonate hemostasis device of claim 2, wherein, The metal core includes any one of zinc-iron alloy core, aluminum alloy core, and copper alloy core.
4. The neonate hemostasis device of claim 1, wherein, An observation area is provided on the rotating plate, and a light-transmitting filling block is provided in the observation area; the hemostatic structure is provided on the light-transmitting filling block; or, the rotating plate is a transparent plate or a semi-transparent plate.
5. The neonatal hemostasis device according to claim 4, characterized in that, The hemostatic structure includes: The pressure plate is in contact with the rotating plate; A hemostatic pad is disposed on the side of the pressure plate opposite to the rotating plate.
