Description

A disposable inflatable tourniquet with a buckle

technical field

The invention relates to the technical field of medical devices, in particular to a disposable inflatable tourniquet with a buckle.

Background technique

Different tourniquet types are made of different materials. Most of them are made of materials with good toughness and almost inelasticity, and they are long and flat. They are suitable for emergency treatment of various types of disaster sites, battlefields, and pre-hospital injuries and bleeding of various limbs, in-hospital patient transfer and limb surgery. One-time use for hemostasis. (The tourniquet is not suitable for blood drawing and blood transfusion: we draw blood strips every day and cannot be used for hemostasis)

However, the tourniquets in the prior art are mostly made of chemical fiber fabrics, and the band is narrow, which is easy to cause pain, the hemostasis effect is unreliable, and the use is inconvenient. After restraining the affected part for a long time, it is easy to cause necrosis of the limb, and it is extremely inconvenient to tighten it after loosening it, which brings great inconvenience to the injured and the doctor.

The Chinese patent with the existing authorization bulletin number CN210019516U discloses an inflatable tourniquet for emergency care, including a tourniquet body, a PE film bag is arranged inside the tourniquet body, and a high-resilience full-body bag is arranged inside the PE film bag.
