Abstract
The utility model discloses a puncture needle for a transfusion system in a marrow cavity, comprising a needle handle and a needle head, wherein the needle head is the structure of a trocar, the puncture needle consists of a puncture needle tube and a puncture needle core, the puncture needle tube is a hollow structure, the puncture needle core is a solid and is arranged in a cavity of the puncture needle tube, the tip of the needle head of the puncture needle core is penetrated through the tip of the puncture needle tube to be tightly joined with the tip of the puncture needle tube, an interface place is smooth and forms into a four-prism solid needle head, the puncture needle tube and the puncture needle core are respectively provided with a base to assemble into the needle handle, the tail of the puncture needle tube outwards extends to be bifurcate and inserted into the base of the puncture needle tube, and the tail of the puncture needle core outwards extends to be bifurcate and inserted into the base of the puncture needle core. The puncture needle has the advantages of being small and exquisite in volume, convenient to carry, and safe and reliable to use, the time for building a transfusion channel can be greatly shortened, the rescue success rate can be improved, and the needle handle and the needle head can not be separated from each other by an external force during operating can be avoided.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used to set up the transfusion path, and a kind of interior transfusion system of medullary cavity that is used to set up transfusion path in the medullary cavity of saying so is more specifically used puncture needle.
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 through patient is input to liquid, medicine, blood in the patient body, but when running into the critical patient because massive hemorrhage, dehydration, shock, sudden cardiac arrest cause peripheral blood vessel to subside, perhaps because large tracts of land body surface burned when causing carrying out the peripheral vein puncture; 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 through 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 through 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 through medullary cavity.
Mostly existing puncture needle needle handle and syringe needle are that the form that sticks with glue links together; It is no problem being used for intramuscular injection and venous transfusion; But because transfusion needs puncture periosteum and cortical bone to get into medullary cavity in the medullary cavity; It is far from being enough making the form that sticks with glue connect the external force that needle handle and syringe needle can bear, and causes needle handle to separate with syringe needle in the use easily or comes off, and syringe needle is stayed complication such as be not drawn out easily in the patient body.
Summary of the invention
The purpose of this utility model provides in a kind of medullary cavity that in one or two minute, just can set up infusion channel transfusion system and uses puncture needle; For clinical or rescue the sick and wounded wartime and win the quality time; Reduce the sick and wounded's percentage of died of wound to a great extent; And can prevent effectively that needle handle from use separating with syringe needle and come off, cause the generation of complication.
For achieving the above object, this utility model comprises needle handle and syringe needle composition, and syringe needle is a trocar design; Be made up of puncture needle tubing and puncture nook closing member two parts, the puncture needle tubing is a hollow-core construction, and the puncture nook closing member is a solid; Be positioned at the cavity of puncture needle tubing, the needle tip of puncture nook closing member passes the tip of puncture needle tubing and most advanced and sophisticated closely linking of puncture needle tubing, and seam smoothly and form one the four solid syringe needle of rib; The puncture needle tubing respectively has a base with the puncture nook closing member, and the base of puncture needle tubing closely is connected through spiral interface with the base of puncture nook closing member, is combined into needle handle; The protruding bifurcated of afterbody of puncture needle tubing, this bifurcated are that the afterbody of puncture needle tubing is directly cut open and outwards dispersed formation, with the puncture needle tubing be one; Be inserted in the base of puncture needle tubing, the protruding bifurcated of afterbody of puncture nook closing member, this bifurcated are that the afterbody of puncture nook closing member is directly cut open and outwards dispersed formation; With the puncture nook closing member be one, be inserted in the base of puncture nook closing member, the spiral interface on the base of puncture needle tubing is a standard transfusion interface; The external diameter of puncture needle tubing is 1.8mm, and internal diameter is 1.5mm, and the length L of the solid syringe needle protuberate basic unit of four ribs is 20-30mm.The optimum length of the solid syringe needle protuberate basic unit of four ribs is 25mm, and the puncture needle tubing is that the flexible alloy material of high strength is processed with the puncture nook closing member.
The principle of this 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, and within several seconds, its puncture needle can get into medullary cavity through periosteum; Take out the puncture nook closing member; Through the liquid of puncture needle tubing infusion first aid continuously, set up infusion channel at short notice, win rescue time.This utility model has also been abandoned traditional needle handle and the gluing connected mode of syringe needle; Make the puncture needle tubing more firm, puncturing and pulling out in the pin process, under huge external force effect with being connected of base; Needle handle and syringe needle can not separate yet; Avoid that needle handle separates with syringe needle in the operating process, syringe needle is stayed in the patient body, and the complication that needle handle is pulled out takes place.
In sum, the utility model has the advantages that: advantages of small volume, easy to carry, safe and reliable, can shorten the time of setting up infusion channel greatly, improve salvage success rate, can avoid that needle handle separates with syringe needle under external force in the operating process simultaneously.
