Sectional type pneumatic hemostatic device

Abstract

The invention discloses a sectional type pneumatic hemostatic device. The device comprises a plurality of airbag segments connected in series through check valves, each airbag segment comprises a breather pipe, an elastic airbag, a left end sealant, a right end sealant and a through hole, wherein the elastic airbag coats the outside of the breather pipe, the left end sealant and the right end sealant are arranged at the two ends of the breather pipe, and bonded with the breather pipe, and the breather pipe is provided with the through hole communicated with the elastic airbag. According to thesectional type pneumatic hemostatic device, the air enters into each elastic airbag through the through holes in the breather pipes, and the elastic airbags begin to expand under the action of an airpressure difference. When the outer sides of the elastic airbags contact wound tissues, the elastic airbags can fit the shapes of the wound tissues better, and the effect of compression hemostasis onthe wound tissues can be achieved. After the expansion of all the elastic airbags is completed, an inflating device can be removed, and because the check valve is in a closed state at this time, thegas in the elastic airbags does not leak, so that the compression hemostasis state is maintained.

Description

Technical field [0001] The invention relates to a segmented airbag hemostatic device, which belongs to the medical technical field. Background technique [0002] In daily life, penetrating injuries caused by sudden accidents often cause heavy bleeding. If treatment is not timely, excessive blood loss will seriously threaten the lives of the wounded. Currently, tourniquets and packing methods are mainly used to stop bleeding in penetrating injuries. Tourniquet hemostasis is the simplest and most effective hemostasis method used in the first aid of massive bleeding in extremities. The purpose of hemostasis is achieved by compressing blood vessels to block blood circulation. However, if the tourniquet is used improperly or used for a long time, it can cause ischemia, necrosis, and disability of the distal limbs, and there are many penetrating injuries that cannot be used to stop the bleeding; and the tamponade hemostasis method uses cotton fabrics. The bleeding cavity or tissue de...

Problems solved by technology

However, if the tourniquet is used improperly, or if it is used for too long, it can cause ischemia, necrosis, and disability of the distal limbs, and there are many penetrating injuries that cannot be stopped with a tourniquet; The bleeding cavity or tissue defect is tightly packed, which is often used in clinical treatment, and the treatment effect is far from meeting the hemostatic treatment of penetrating injuries
