Abstract
The invention comprises a handle and a drill bit, wherein the drilling bit has a trocar structure consisting of two parts, namely a sleeve and a tube core needle. The sleeve has a hollow structure, the tube core needle is a solid and is positioned in a cavity of the sleeve, a tip end of a needle head of the tube core needle passes through a tip end of the sleeve to be tightly connected with the tip end of the sleeve so as to form a four-edge solid drill bit, each of the sleeve and the tube core needle is provided with a base, the base of the sleeve and the base of the tube core needle are tightly connected by a spiral interface, the handle is provided with a connector made from magnetic materials, the connector is a cylinder with a pentagon cross-section, a part for connecting the base of the sleeve and the connector on the handle is a cylinder cavity with a pentagon cross-section, the bottom of the cavity is provided with an iron sheet, the connector and the base of the sleeve are tightly connected with the iron sheet through the magnetic materials, and the spiral interface on the base of the sleeve is a standard transfusion interface. The invention has the advantages of small volume, easy carrying and safe and reliable use, and can greatly shorten the time for establishing a transfusion path and improve the success ratio of rescue.
Description
Technical field
The present invention 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 invention is to provide a kind of manual transfusion apparatus in bone marrow cavity that in one or two minute, just can set up infusion channel,, reduce the sick and wounded's percentage of died of wound to a great extent for clinical or rescue the sick and wounded wartime and win the quality time.
For achieving the above object, the present invention includes handle and drill bit, 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, be positioned at telescopic cavity, the needle tip of stylet passes telescopic tip and closely is connected with telescopic tip, form one four rib solid bit, sleeve pipe and stylet respectively have a base, the base of telescopic base and stylet closely is connected by spiral interface, the union joint that magnetic material is made on the handle, union joint is that a cross section is pentagonal cylinder, the position that telescopic base is connected with the handle upper binding head is that a cross section is pentagonal cylinder cavity, and cavity bottom has an iron plate, and union joint closely is connected with iron plate by magnetic material with telescopic base, spiral interface on the telescopic base is a standard transfusion interface, 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 invention 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, advantage of the present invention is: volume is small and exquisite, easy to carry, safe and reliable, can shorten the time of setting up infusion channel greatly, improve salvage success rate, and handle can be reused.
