Abstract
The utility model belongs to a pre-filled composite medicine power-driven injector in the field of medical equipment. A thread sliding rod and a push plug are arranged in a needle cylinder filled with different liquid medicine capsules; a push plate is arranged in the push plug, is fixed by the thread sliding rod, and is moved along an inner wall of the needle cylinder along the rotation of the thread sliding rod; a motor is connected with the thread sliding rod through a wheel gear and drives the thread sliding rod to rotate; a needle head is arranged on the bottom part of the needle cylinder; one end of the needle head is inserted in the needle cylinder so as to be used as an inner needle head; the other end of the needle head is used as an injection needle head; a needle passage of the inner needle head is in a straight shape, a cross shape or a T shape; when medicine is administrated, a power supply is switched on, the motor drives the thread sliding rod to rotate, the push plate squeezes the capsules, the inner needle head punctures the capsules, and liquid medicine enters into subcutaneous tissues or muscle. According to the injector, injection administration processes of various medicines can be completed at a time, the quantitation is accurate, and the injector is convenient to carry, is simple to operate, effectively solves the problem of composition of various first-aid medicines, and is particularly applied to self-aid and buddy-aid occasions.
Description
Affiliated technical field
This utility model belongs to the medical equipment field, is specifically related to a kind of pre-filled combination drug motoring syringe.
Background technology
Early stage emergency care of trauma is the key link that improves survival rate under wartime or emergency (disaster, the accident etc.) situation.The very first time is carried out the related drugs first aid of " delay time, save one's life " behind the acute injury, becomes the research focus of more and more paying close attention to.At present; The compound easily first aid medicine of the oneself of critical wound does not have the research of series matching in the world; Treatment in the past is in reliable medical system, uses various liquid preparations safely and effectively through well-trained professional, and side effect is dropped to minimum level.But in case of emergency, the wounded save oneself and when rescuing mutually, and are how convenient, use first aid medicine safely and effectively, control wounded's traumatic condition to greatest extent, preserve wounded's life and are still a great problem.
In U.S. army's equipment, Xi Leite injection of morphia device is the preliminary trial that addresses this problem, and through self-service injection single medicine---morphine, reaches calm, analgesic effect.But this device can't satisfy the situation when needing multiple medicinal application, also do not have the method report of combination drug independence administration, and this is the major issue that following emergency treatment development pole might face.
Summary of the invention
The purpose of this utility model is not have the self-service doser of combination drug in order to overcome prior art; Can't satisfy that the wounded save oneself and need use the defective of multiple medicine when rescuing mutually; For people provide a kind of quantitatively accurate, pre-filled simply and easily combination drug motoring syringe.
The purpose of this utility model provides that following technical proposals realizes.
The pre-filled combination drug motoring syringe of this utility model is characterized in that pre-filled combination drug motoring syringe is made up of plunger, pre-filled combination drug syringe and syringe needle jointly, and said pre-filled combination drug syringe is for be equipped with the capsular syringe of liquid medicine of different cultivars successively according to the injection sequencing; The screw thread slide bar is installed in the syringe; Syringe opening one end is equipped with plunger, and plunger is equipped with push pedal near syringe opening one end for the band cylindrical shell at the end in the cylindrical shell; Push pedal is fixed by the screw thread slide bar; And with the rotation of screw thread slide bar along move in the syringe, push pedal and plunger are equipped with motor and battery between the bottom, motor is connected with the screw thread slide bar through gear; And driving the rotation of screw thread slide bar, the switch of motor is installed in the plunger outside; The syringe bottom is equipped with syringe needle, and syringe needle is the hollow cylinder of two ends needle pattern, and hollow space is a needle track; Syringe needle one end inserts in the syringe, and as interior syringe needle, the other end is as injection needle; The needle track of interior syringe needle is straight-through shape or cross or T font, and the needle track of injection needle is straight-through shape.
During administration, energized is under the driving of motor; The screw thread slide bar rotates, and makes push pedal to syringe bottom squeeze capsule, and interior syringe needle is worn out each capsule successively; Liquid medicine gets into subcutaneous or muscle through interior syringe needle and injection needle in the capsule, thereby accomplishes the administration process of combination drug.
The pre-filled combination drug motoring syringe of this utility model is a power with the motor, once can accomplish multiple medicine independence drug administration by injection process; Quantitatively accurately, utensil is easy to carry, and is simple to operate; Efficiently solve the compound problem of multiple first aid medicine; Need not pass through well-trained professional, be specially adapted to the occasion that the wounded save oneself and rescue mutually, the self-service first aid during for wartime or emergency provides new equipment.
