Description

Novel marrow transfusion puncture device

Technical Field

The invention relates to the technical field of ankle joint support, in particular to a novel bone marrow transfusion puncture device.

Background

The marrow cavity transfusion is an emergency transfusion method established under special conditions, and is a quick, safe and effective alternative way for critical patients who cannot normally carry out venipuncture.

At present, the marrow cavity puncture infusion device mainly comprises 3 types: an intramedullary injection device, a bone marrow infusion gun and a FAST1 infusion set. Among them, an injection device in a bone marrow cavity (EZ-IO) is marketed domestically, but it is expensive, requires consent from family members of patients before use, and is difficult to popularize and apply in a short period of time. In order to meet the requirements of emergency treatment of critical patients in clinic, according to the principle, the bone marrow puncture needle is adopted in the emergency department of hospitals to complete the operation, and the bone puncture bag is low in price, easy in material obtaining and wide in application. In actual clinical work, for critical patients, medical staff successfully establish a marrow cavity infusion path, but still need to continuously and repeatedly inject rescue medicines, and due to the lack of a special connecting pipeline, the connection between a bone puncture needle and an infusion apparatus (or a blood transfusion apparatus) can only be disconnected, and the connection is repeated for multiple times, so that the bone puncture needle is easy to shift and fall off, the liquid medicine is caused to seep, the limb swelling, infection, periosteum syndrome and the like of the punctured part of the patient are caused, the pain and the medical expense of the patient are increased, the workload of nurses is increased, and the medical safety potential is increased.
