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
The invention belongs to medical infusion utensil technology, relate 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 30～60S, 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 objective of the invention is medullo-puncture needle to be penetrated in the medullary cavity easily, carry out quick intravenously administrable fluid infusion by the mechanical energy releasing device.
The object of the present invention is achieved like this: utilize the mechanical potential driving marrow puncture needle that clockwork spring discharged that unrolls to enter in the medullary cavity.

The specific embodiment
Referring to Fig. 1, pusher dog (5) is fixed on the shifting block dish (8) by pusher dog alignment pin (2), and pusher dog (5) can rotate around pusher dog alignment pin (2), and its end is connected with an end of shifting block spring (4).Dynamic resistance circle (7) is fixed on the shifting block dish (8) by clamp nut (6), and the other end of shifting block spring (4) in clamping.The clockwork spring (11) that unrolls is fixed on the clockwork spring seat of shifting block dish (8) by clockwork spring external fixation screw (10) and clockwork spring bayonet lock (13), and the clockwork spring that unrolls (11) is in tensioning energy storage state.Stops (14) also is to be fixed on the shifting block dish (8).
Referring to Fig. 2, spill dial (15) is fixed on the end of medullo-puncture needle core print seat (17) by clamp nut (16).
Referring to Fig. 1 and Fig. 2, two parts are combined into one by the fixing threaded hole (1) on the protecting cover (9).When starting, remove clockwork spring bayonet lock (13) to the restriction of the clockwork spring that unrolls (11) of tensioning energy storage, driving shifting block dish (8) rotates around bolster (12), dynamic resistance circle (7) clamping that one end of shifting block spring this moment (4) is fastened on bolster (12) spindle nose is motionless, and the other end is supporting the end of pusher dog (5), the rotation of shifting block dish (8) forces in pusher dog (5) and shifting block spring (4) link and moves, the shifting block stops (14) that speeds away is stretched, the card that enters dial (15) is worked as, stirring dial (15) rotates, driving medullo-puncture needle core print seat (17) simultaneously rotates, medullo-puncture needle trocar sheath (18) and medullo-puncture needle head (19) link with it, and medullo-puncture needle head (19) just can penetrate in the medullary cavity smoothly.For the ease of the control paracentesis depth, on medullo-puncture needle trocar sheath (18), the depth-adjustable needle insertion stopping means is set, promptly be provided with external screw thread at medullo-puncture needle trocar sheath (18) middle part, on this threaded portion, be rotary with clamp nut (20) and adjusting nut (21), by adjusting the position of adjusting nut (21) on medullo-puncture needle trocar sheath (18), the medullo-puncture needle head (19) that adjusting nut (21) front portion is exposed is of convenient length, and uses clamp nut (20) to its positioning and locking then.
Claims (2)
1. disposable bone marrow in-cavity injection apparatus, it is characterized in that: pusher dog (5) is fixed on the shifting block dish (8) by pusher dog alignment pin (2), and pusher dog (5) can rotate around pusher dog alignment pin (2), and it is terminal to be connected with an end of shifting block spring (4).Dynamic resistance circle (7) is fixed on the shifting block dish (8) by clamp nut (6), and the other end of shifting block spring (4) in clamping.The clockwork spring (11) that unrolls is fixed on the clockwork spring seat of shifting block dish (8) by clockwork spring external fixation screw (10) and clockwork spring bayonet lock (13), and the clockwork spring that unrolls (11) is in tensioning energy storage state.Stops (14) also is to be fixed on the shifting block dish (8).Spill dial (15) is fixed on the end of medullo-puncture needle core print seat (17) by clamp nut (16).
2. a kind of disposable bone marrow in-cavity injection apparatus according to claim 1 is characterized in that: be provided with external screw thread at medullo-puncture needle trocar sheath (18) middle part, be rotary with clamp nut (20) and adjusting nut (21) on this threaded portion.
