Description

The multi-port jet injection system that is used for local anesthesia
Technical field
This utility model relates to field of medical, relates in particular to a kind of multi-port jet injection system that is used for local anesthesia.
Background technology
Existing employing has the local anesthesia of pin injection system to use syringe, often needs repeatedly in use, multi-direction acupuncture injecting anesthetic medicine, just can reach the local anesthesia effect of expection.And this repeatedly, multidirectional acupuncture anesthesia mode not only brings misery to the patient easily, wastes time and energy during operation, brings certain work difficulty to the medical worker.And; The existing pin type local anesthesia set that has that uses is manual type; Because hand gun is in the process of injection, very difficult assurance propelling anaesthetic at the uniform velocity, the pain increased and anaesthetic advances flow velocity to change can to cause the patient; And then make the patient produce the feared state of mind, also can increase the weight of doctor's mental pressure.
Jet injection (claiming Needleless injection again) refers to the instantaneous pressure that utilizes machinery to produce, and promotes medicament (liquid or lyophilized powder) through a very thin nozzle, forms high-pressure spray, passes skin and directly permeates into hypodermic process.The jet injection technology not only can be used for injecting some macromolecular drugs and (uses like the injection of insulin of vaccination, diabetics, anemia patient's erythropoietin; And in disease patients such as some tumor injection somatomedin and interferon etc.); But also can be used to inject small-molecule drug, as Li Kaduoyin, midazolam and ketamine etc.
Compare with traditional pin injecting method that has, jet injection have a series of advantage as: simple to operate, drug absorption is effective, reduce injection pain to a certain extent, eliminate the acupuncture infection, skin need not to disinfect in alcohol, cross infection can not take place, can inject voluntarily, reduce that medical waste and " white " are polluted etc.Thereby; Jet injection need to be specially adapted to the patient of long-term automedication treatment, the patient that probably pin sense is arranged and child's daily administration; And the diseases prevention and treatment under extensive prophylactic immunization and the field work condition, the health support of vital emergent event, thereby just obtaining increasingly extensive application aspect the administrations such as polypeptide protein medicine, therapeutic genes medicine, vaccine, anesthetis.When using jet to annotate,,, be fit to extract tonsil, have tooth pulled out and carry out the local anesthesia of operations such as cornea so that the tip sensor of people's affective neuron also has little time stimulation is reacted, thereby can not produce pain because injection speed is very fast.In addition, jet injector can also be used for hemostasis, and when particularly the surgeon rescued the internal hemorrhage patient, available jet injector temporarily stopped up blood capillary along hemorrhage " ejaculation " a kind of special rubber polymer, stops blooding.
Although jet injector has emerged for many years, the basic function of existing jet injector does not change, and is mostly the single-body type jet injector.Application number is that 200610111033.9 patent has proposed a kind of needle-free jet injection formula delivery device with a plurality of nozzles; But the nozzle of this delivery device is fixed in the shell; Each other distance and angle are unadjustable; Can only be used for the medicine injection in the zonule very, and shared same push rod of its all pistons and active element, each nozzle also can only spray with a kind of medicine in the same time.
Summary of the invention
