Abstract
The utility model comprises a handle and a drill, and the drill adopts a puncture trocar structure, and comprises a sleeve and a pipe core needle. The sleeve adopts a hollow structure, the pipe core needle adopts a solid body and is positioned in the cavity of the sleeve, the tip end of the needle head of the pipe core needle is closely connected with the tip end of the sleeve through penetrating the tip end of the sleeve, so as to form a four-edge solid drill, the non-point end of the pipe core needle is connected with the handle, a plastic base and a standard spiral interface for transfusion are arranged at the non-point end of the sleeve and the non-point end of the sleeve is closely connected with the handle, the external diameter of the sleeve is 1.8mm and the internal diameter thereof is 1.5mm, the length L of the four-edge solid drill extending out of the base is 20 to 30mm, the optimum length of the of the four-edge drill extending out of the base is 25 mm, and both the sleeve and the pipe core needle are made of high-intensity flexible alloy materials. The utility model has the advantages the volume is small, the carrying is convenient, the application is safe and reliable, the time of building the transfusion channel can be greatly shortened, and the attainment rate of salvage is improved.
Description
Technical field
This utility model relates to a kind of infusion set, a kind of manual transfusion apparatus in bone marrow cavity that is used to set up transfusion path in the medullary cavity of saying so more specifically.
Background technology
At present, what hospital carried out that infusion treatment adopts to patient is the vein blood vessel transfusion, it is that vein blood vessel by patient is input to liquid, medicine, blood in the patient body, but when running into the critical patient owing to massive hemorrhage, dehydration, shock, sudden cardiac arrest cause peripheral blood vessel to subside, when perhaps causing to carry out the peripheral vein puncture owing to the large tracts of land body surface burned, or puncture failure repeatedly, cause rescue failure to patient.According to statistics, if wartime, the hemorrhagic shock wounded can set up infusion channel in initial 10 minutes, will reduce its percentage of died of wound greatly, traditional venous transfusion on average needed just can set up in 12 minutes, and only needed 1 minute just can set up the venous transfusion path by medullary cavity, for the life that gives emergency treatment to a patient has won valuable time.
The mechanism of transfusion is relevant with the internal anatomy of osseous tissue in the medullary cavity, medullary cavity is connected with body circulation large vein with the nourishing vein by breathing out the Fu Shi central canal, this just can guarantee that the liquid of importing medullary cavity can get back to body circulation large vein rapidly, reaches and effect that the central vein transfusion is same; In addition, medullary cavity can not subsided along with subsiding of peripheral vein, so when peripheral vein subsides, still can liquid medicine etc. be input in patient's the body by medullary cavity.
Summary of the invention
The purpose of this utility model provides a kind of manual transfusion apparatus in bone marrow cavity that just can set up infusion channel in one or two minute, for clinical or rescue the sick and wounded wartime and win the quality time, reduces the sick and wounded's percentage of died of wound to a great extent.
For achieving the above object, this utility model comprises handle and drill bit, and drill bit is a trocar design, comprises sleeve pipe and stylet two parts composition.Sleeve pipe is a hollow-core construction, stylet is a solid, is positioned at telescopic cavity, and the needle tip of stylet passes telescopic tip and closely is connected with telescopic tip, form one four rib solid bit, non-needle point one end of stylet is connected with handle, and non-needle point one end of sleeve pipe has a plastic feet, has transfusion master screw interface, closely be connected with handle, telescopic external diameter is 1.8mm, and internal diameter is 1.5mm, and the length L of four rib solid bit protuberate basic units is 20-30mm.The optimum length of four rib drill bit protuberate basic units is 25mm, and sleeve pipe and stylet are that the flexible alloy material of high strength is made.
Principle of the present utility model is to have used a kind of principle and technology of the trocar, the site of puncture is selected the long bone on tibia or the arm for use, within several seconds, its drill bit can enter medullary cavity by periosteum, take out stylet, by the liquid of sleeve pipe infusion first aid continuously, set up infusion channel at short notice, win rescue time.
In sum, the utility model has the advantages that: volume is small and exquisite, easy to carry, safe and reliable, can shorten the time of setting up infusion channel greatly, improves salvage success rate.
