Description
Technical field
This utility model relates to area of medical devices, specifically a kind of Medical anesthetic pin.
Background technology
Medical angle, the implication of anesthesia by medicine or additive method, patient's entirety or local is temporarily lost sensibility, to reach painless object, for operative treatment or other medical examination treatment provide condition.Anesthesia can be roughly divided into general anesthesia and local anesthesia two class.General anesthesia, be " sleeping state " as the saying goes, patient realizes disappearance, and whole-body muscle relaxes, and also can not experience pain.Local anesthesia, as the term suggests, the just anesthesia at some position of health.When modal local anesthesia is such as had tooth pulled out, doctor first can inject some local anesthetics, in order to avoid you feel pain near your root of the tooth.Generally, local anesthesia also comprises epidural anesthesia or subarachnoid anesthesia (being commonly called as " lumbar anesthesia "), namely everybody " the half body anesthesia " of ripe title.Anesthetist can carry out operation in the middle of your back, and then you just feel that the lower part of the body is fallen by fiber crops: though you know that scalpel is in cutting, can not experience pain.
In anaesthesia process, anesthetic needle must be used, when anaesthetizing the body part of patient, usual meeting controls narcotic consumption according to performed the operation area size, the anesthetis consumption of existing anesthetic needle can only input according to the experience of taking up a job as a doctor of doctor, part is caused to anaesthetize not exclusively, or narcotic consumption is inadequate, anaesthetize when performing the operation and not completing and lost efficacy, great pain is caused to patient, most of patients needs to carry out hands art in multiple places of health simultaneously simultaneously, change anesthetic needle so frequently comparatively to lose time, also comparatively delay the state of an illness of patient simultaneously.
At present, hospital clinical is the injection needle of conventional needle as anesthesia is used, only has a pin hole of front end, injection speed is slower, extend anesthesia duration, easily cause the appearance of post-operative complication, and in most cases implement intramuscular injection, a large amount of anesthetic liquid medicines is all enter in muscle by a pin hole, adds the misery of patient.The operation of usual time length must adopt general anesthesia, and general anesthesia to be with to patient and to be served sequela, as excessive phlegm, pulmonary infection etc., and the hardness of the site of puncture of common pin needle tip is in dura mater puncture anaesthesia process, not easily reach requirement, make puncture difficulty, and pin hole easily blocks, not easily circulate, anaesthetic effect is reduced.
