Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, especially a kind of blood expelling hemostat of double-layer balloon structure. BACKGROUND

[0002] In extremity surgery, in order to reduce patient blood loss, while improving surgical efficiency, shorten the operation time, often need to implement blood expelling and hemostasis steps, by blocking blood supply to reduce bleeding, so as to provide clear vision for surgery, better expose the surgical area. Tourniquet is divided into rubber tourniquet, inflatable tourniquet, among which inflatable tourniquet is divided into manual type and electric type, commonly used for adult and child extremities, composed of air bag body and inflation device, with wide application range. Blood expeller also plays an important role in surgery, which also blocks blood to the proximal end of the limb by pressure. The current blood expelling belt is made of rubber sheet with good elasticity, which is easy to cause skin injury during blood expelling. The current market blood expelling device has inflatable blood expeller and elastic tightening blood expelling ring. Traditional blood expelling tourniquet is made of silicone material, which needs to be reused after high temperature and high pressure disinfection, and the inflation hole of blood expelling sleeve is hard rubber valve with high hardness.

[0003] The existing blood expelling hemostat with soft membrane, for example, application number: 202221437767.7, applicant: Auckland Medical Technology (Sichuan) Co., Ltd. uses soft membrane to cooperate with gel valve body to ensure the softness of the entire blood expeller, improve the comfort of patients and increase the blood expelling hemostatic effect. This structure has the problem of poor pressure resistance. In practice, for the case that requires greater pressure, such as obese target object, the blood expelling hemostatic effect is not good under general pressure index, and greater pressure is needed for blood expelling hemostasis. However, this structure cannot bear greater pressure.
