Technical field

The invention belongs to the technical field of medical rescue beds, and specifically refers to an emergency rescue bed for severe abdominal hemorrhage.

Background technique

Abdominal bleeding includes extra-abdominal bleeding and intra-abdominal bleeding. Injury to the outside of the abdominal cavity will cause bleeding outside the abdominal cavity and may also lead to bleeding inside the abdominal cavity. During the process of abdominal trauma and heavy bleeding, medical care needs to be fixed and compressed to reduce the blood flow around the abdominal cavity and avoid The patient suffered massive abdominal bleeding and died due to excessive blood loss.

The patient is in a state of severe bleeding and cannot perform effective hemostasis compressions. Special compressions must be performed by medical staff. An ambulance bed pusher is also required. In order to treat one patient, at least two or more ambulance personnel are required. It occupies a lot of space, and the ambulance bed cannot only be used for the symptom of abdominal hemorrhage. It should also be universal in the placement process of regular patients. Therefore, it is necessary to design an ambulance bed that can reduce the loss of medical care without affecting the ambulance bed.
