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 for infusing in the medullary cavity, conveniently to carry out fast administration fluid infusion, especially for the critical patient first aid.
Background technology
In clinical emergency treatment, can in time, effectively set up the success or not that infusion channel is directly connected to treatment.The conventional method of setting up venous access has peripheral vein, central venous puncture and venotomy etc.For critical patient, the normal contraction of peripheral vein subsided, the puncture difficulty; The foundation of central vein has certain difficulty; Venotomy is length consuming time again, and affect the enforcement of resuscitation.
Summary of the invention
Under emergency situation, the best approach of setting up the emergency intravenous infusion passage is 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 time that body circulates 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 the valuable time for rescuing life.The advantage of marrow cavity transfusion: simple to operate, be easy to grasp, success rate is high, can finish at short notice, can in 30～60S, set up the intraosseous infusion 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 affect ventilation and closed cardiac massage, thereby for clinical rescue provides convenience, can all can in medullary cavity, use at the medicine that intravenous uses, comprise blood transfusion.
The objective of the invention is by the mechanical energy releasing device medullo-puncture needle to be penetrated in the medullary cavity easily, carry out quick intravenously administrable fluid infusion.
The object of the present invention is achieved like this: the mechanical potential of utilizing the clockwork spring that unrolls to discharge drives marrow puncture needle and enters 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 the outer fixed screw (10) of clockwork spring 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 driver plate (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 driver plate (15) is worked as, stirring driver plate (15) rotates, driving simultaneously medullo-puncture needle core print seat (17) 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, at medullo-puncture needle trocar sheath (18) the depth-adjustable needle insertion stopping means is set, namely 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) at this threaded portion, 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 then uses clamp nut (20) to its positioning and locking.
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), 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 the outer fixed screw (10) of clockwork spring 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 driver plate (15) is fixed on the end of medullo-puncture needle core print seat (17) by clamp nut (16).
