Abstract

The invention discloses an injection device of marrow cavity in the shape of pistol, comprising a handle, a switch, a driving device, a connector of rotary head, a special rotary head of sleeve needle and a power source. Wherein, the power source, the switch and the driving device are connected in series while the driving device is the main part of said pistol-shaped injection device whose head is the connector of converter which is the external working part of said pistol-shaped injection device; the inner part of pistol-shaped injection device is connected to the driving device while its outer part is connected to the special rotary head of sleeve which is comprised by a injection needle whose tip is in the structure of double inclined blade and the inner core needle whose tip is in the structure of cone. The invention has the advantages of small volume, using the battery as power, carrying portably, safe and reliable usage, reduced time and improved rescue success ratio.

Description

Technical field [0001] The invention relates to a medical device, more specifically, to design an intramedullary injection device for emergency use. Background technique [0002] In the clinical rescue of critically ill patients, the key is to establish good venous access, which is the prerequisite for determining whether the rescue is successful, especially for patients with shock and massive blood loss, which can cause a series of severe microcirculation disorders, subcutaneous vein collapse, and vasoconstriction , Blood stasis, high viscosity, increased permeability, which brings certain difficulties to venipuncture. Needle blockage, no blood return after puncture, and subsequent extravasation, and vascular collapse and hardening are the main reasons for puncture failure, and delays in rescue time, doctors are unable to do anything because they cannot use medicine. The nurse looked for blood vessels around the patient, rubbing and tapping lightly, trying to expose the blood ve...
