Description
Technical Field
The invention relates to the field of medical equipment, in particular to a bone marrow puncture transfusion device.
Background
The venous access is a life access, and whether the venous access can be quickly established and timely used in the emergency treatment process is a key place for successfully rescuing patients. However, in clinical emergency treatment, peripheral venous access is usually adopted for transfusion, and part of patients cannot effectively establish a venous access in time due to venous collapse, shrinkage and the like, and other measures must be immediately taken for replacement so as to avoid delaying the rescue time. The American Heart Association clearly proposes in the "2005 cardiopulmonary resuscitation guide" that "the patient is a person in need of emergency rescue, and repeatedly puncturing for 3 times or 90 seconds fails to puncture the patient, and the marrow cavity transfusion is recommended, and the method is suitable for all people. In recent years, intramedullary transfusion has been increasingly focused by medical staff as a rapid, safe and effective cyclic reconstruction method. Bone marrow cavity transfusion and venous cavity transfusion are parallel effective means of transfusion, and bone marrow transfusion is commonly used in first aid and infant transfusion.
Compared with intravenous infusion, the bone marrow infusion has higher professional requirements for medical staff, and a bone marrow puncture infusion device which is simple to use and convenient to operate does not exist in the prior art.
