Embodiment Construction

[0009] see figure 1 , the claw (5) is fixed on the dial (8) by the claw positioning pin (2), the claw (5) can rotate around the claw positioning pin (2), and its end is connected with the toggle spring (4) connected at one end. The stop ring (7) is fixed on the dial plate (8) by the fastening nut (6), and clamps the other end of the dial spring (4). Rewind spring (11) is fixed on the clockwork seat of shifting head plate (8) by clockwork outer fixing screw (10) and spring bayonet (13), and rewind spring (11) is in tension energy storage state. Stop block (14) is also fixed on the dial (8).

[0010] see figure 2 , the concave dial (15) is fixed on the end of the bone piercing core seat (17) by a fastening nut (16).

[0011] see figure 1 and figure 2 , the two parts are combined into one through the fixing screw holes (1) on the cover (9). When starting, remove the restriction of the spring bayonet (13) to the rewinding spring (11) of the tensioned energy storage, drive...

Abstract

In emergency, the optimal method for building an emergency transfusion channel is intra-bone marrow transfusion which ensures that a medicament and liquid transfused into the marrow cavity can quickly and effectively enter blood circulation. The time for the medicament administrated from intra-bone marrow to enter systemic circulation is basically the same as that for the medicament which is administrated from central veins to enter the systemic circulation, but is quicker than that for the medicament which is administrated from peripheral veins to enter the systemic circulation. For critical patients who cannot be treated by regular vein puncture, the intra-bone marrow transfusion may be a first choice instead of the traditional venous transfusion is quick, safe and effective rescue technology and saves precious time for life rescue. In the invention, a medullo-puncture needle is penetrated into the marrow cavity by a mechanical energy releasing device to feed the medicament and the liquid into the veins. The disposable intra-bone marrow injection device drives the medullo-puncture needle into the intra-bone marrow by the mechanical energy released by winded clockwork springs.

Description

technical field [0001] The invention belongs to the technology of medical infusion equipment, and relates to an equipment for intraosseous cavity infusion, which is convenient for quick drug administration and rehydration, and is especially used for emergency treatment of critically ill patients. Background technique [0002] In clinical first aid, whether the infusion channel can be established in time and effectively is directly related to the success of the treatment. The general methods of establishing venous access include peripheral vein, central venipuncture and phlebotomy. For critically ill patients, peripheral veins often shrink and collapse, making puncture difficult; the establishment of central veins is difficult; phlebotomy takes a long time and affects the implementation of resuscitation. Contents of the invention [0003] In critical situations, the best way to establish an emergency infusion channel is intraosseous infusion. Drugs and fluids infused into...
