Abstract
The utility model relates to a marrow cavity puncture driver. In an emergent situation, the best way to build an emergency treatment transfusion passage is marrow cavity transfusion. Medicine and liquor transfused inside a marrow cavity can enter into blood circulation quickly and effectively, and the time of dosing via the marrow cavity and then entering into body circulation is identical to the time of dosing via a central vein and smaller than the time of dosing via a peripheral vein. For a severe patient incapable of being punctured via normal veins, marrow cavity transfusion can be a preferred replacement method of normal vein transfusion, is the fast, safe and effective rescue technology, and can save valuable time for saving lives. By adopting the principle of spirally advancing in a reverse or forward direction and by aids of manual feed pressure, the marrow cavity puncture driver has a function of rotating forwards, provides driving force for various marrow puncture needles, and leads medullo-puncture needles to be conveniently punctured into marrow cavities under the action of the driving force so as to dose and infuse fluid to veins quickly.
Description
Technical field
This utility model belongs to medical infusion utensil technology, relates to a kind of utensil that is used for transfusion in the medullary cavity, conveniently to carry out administration fluid infusion fast, especially for the critical patient first aid.
Background technology
In clinical emergency treatment, can set up the success or not that infusion channel is directly connected to treatment in time, effectively.The conventional method of setting up venous access has peripheral vein, central vein puncture and venotomy etc.For critical patient, the normal contraction of peripheral vein subsided, the puncture difficulty, central vein establish certain degree of difficulty, venotomy length consuming time again, and influence the enforcement of resuscitation.
Summary of the invention
Under emergency situation, the best approach of setting up the emergency treatment infusion channel is a marrow cavity transfusion.Medicine and the liquid of input in the medullary cavity can enter blood circulation rapidly, effectively, and it is roughly the same to enter the body circulation time through medullary cavity administration and central vein administration, faster than the peripheral vein administration.For critical patient that can't conventional venipuncture, marrow cavity transfusion can be used as the first-selected alternative route of traditional venous transfusion, is a kind of quick, safe and effective rescue technology, has won valuable time for rescuing life.The advantage of marrow cavity transfusion: simple to operate, be easy to grasp, the success rate height can be finished at short notice, can in 30～60 seconds, set up bone marrow transfusion path, for rescue work has won the quality time, the intraosseous infusion art is workable, is easy to medical personnel and grasps very short time, the tibia marrow cavity transfusion does not influence ventilation and closed cardiac massage, thereby for clinical rescue provides convenience, can all can in medullary cavity, use, comprise blood transfusion at the medicine that intravenous uses.
The purpose of this utility model is by the reverse of screw propulsion or forward principle, pressure generation turning effort forward by manual feed, for various marrow puncture needles provide driving force, under the effect of this power, medullo-puncture needle is penetrated in the medullary cavity easily, carry out quick intravenously administrable fluid infusion.
The purpose of this utility model is achieved in that holds handle, when pushing forward, because the rib-loop on the rib-loop leading screw and the inclined plane of the rib-loop on the external rotation part interact, produce turning moment, cause the external rotation part to be rotated in the forward, and the rib-loop leading screw is wanted counter-rotating, but because spring leaf is pushed down check sheet downwards, make it block non-return the wheel, make the rib-loop leading screw can not counter-rotating, and the external rotation part is except that a little resistance of puncture needle, there is not other resistance, therefore the external rotation part will be by being rotated in the forward, thereby driving puncture needle rotates on skeleton, under the dual function of extruding and rotation, puncture needle pierces to bones, after arm is removed pushing force, the elastic force of back-moving spring will make external rotation part and rib-loop leading screw do opposite motion, and at this moment the clamping resistance that is subjected to of puncture needle can be greater than the moment that is rotated in the forward of rib-loop leading screw, check sheet can not stop being rotated in the forward of leading screw, therefore the rib-loop leading screw will be done and be rotated in the forward, and puncture needle is motionless substantially in skeleton, and apparatus is finished and resetted, arm is applied thrust once more, but puncture needle is forward rotation again, so repeatedly several times, can penetrate in the medullary cavity.
