Description

Bone marrow cavity puncture fixing device Technical Field The utility model relates to the technical field of medical appliances, in particular to a bone marrow cavity puncture fixing device. Background The marrow cavity puncture technology is one emergency transfusion technology to utilize blood vessel passage in marrow cavity to make transfusion, and has special puncture needle to drill into long bone marrow cavity, transfusion unit to connect the puncture needle to the other end, and non-collapsible micro venous network inside the marrow cavity to absorb the liquid fast and transfer the liquid to systemic circulation. The technology is mainly used for rescuing critical patients, particularly for the situation that venous access cannot be established and rapid transfusion is needed, provides another life access for emergency patients, and has extremely high clinical application value. Bone marrow cavity puncture technology is of great importance in emergency treatment, but the prior art lacks an effective puncture needle fixing device. After the vital signs of the patient are slightly stable, the patient needs to go out to be checked for further treatment, and the puncture needle penetrating into the bone marrow cavity is clinically fixed at present mainly through a medical adhesive tape, so that the fixing mode is not firm enough when the patient wears the puncture needle to move, and the puncture needle and the infusion device have risks of moving and falling. Disclosure of utility model The utility model provides a fixing band, which solves the problems of weak fixation, easy movement and falling of a bone marrow cavity puncture needle in the prior art. In order to solve the technical problems, the utility model is realized as follows: the utility model provides a bone marrow cavity puncture fixing device, which comprises: A main body having a first through hole penetrating in a first direction, the first through hole being for fixing a puncture needle; an adhesive means connected to the body for adhering to the skin of a user to secure the body to the skin of the user; The communicating vessel is fixedly connected to the main body and is used for connecting the puncture needle and the infusion tube.
