Abstract
The utility model discloses an anesthetic needle head which comprises a hollow cylinder needle body, wherein a solid puncturing part with a conical front end is arranged at the end part of the front end of the needle body; three to six agentia outlet holes I arranged uniformly are formed in the left side and the right side of a side wall at the front end of the needle body respectively in a symmetrical manner; three to six agentia outlet holes II arranged uniformly are formed in the front side and the rear side of a side wall at the front end of the needle body respectively in a symmetrical manner; a connection port of an entry needle drum is connected onto the end part of the rear end of the needle body; and a connecting through hole communicated with the internal part of the needle body is formed in the center of the connection port of the entry needle drum. The anesthetic needle head has the following prominent advantages: the structure is simple, the use is convenient, a plurality of holes are used simultaneously for dosing, the injection speed is high, and the injection time is short, so that the anesthetic time is greatly shortened, and postoperative complications are effectively avoided; the agentia outlet holes are not easy to be blocked, and the anesthetic effect is fast and excellent, so that suffering of a patient is relieved; and the solid puncturing part with the conical front end is arranged at the end part of the front end of the needle body and has high hardness.
Description
Technical field:
This utility model relates to the injection needle technical field, particularly a kind of anesthesia syringe needle.
Background technology:
In surgical operation, anesthesia is a preoperative operating technology important and requirement is very strict, at present, on hospital clinical, be the injection needle of common syringe needle as anesthesia usefulness used, have only a pin hole of front end, injection speed is slower, prolong anesthesia duration, caused the appearance of post-operative complication easily, and in most cases implemented intramuscular injection, a large amount of anesthesia medicinal liquids all is to enter in the muscle by a pin hole, has increased patient's misery.Usually long operation of time must be adopted general anesthesia, and the general anesthesia meeting brings some sequela to the patient, as excessive phlegm, pulmonary infection etc., and the hardness of the site of puncture of common pin syringe needle front end is in dura mater puncture anesthesia process, be difficult for reaching requirement, make the puncture difficulty, and pin hole stop up easily, be difficult for circulation, anaesthetic effect is reduced.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, inject time the short and high anesthesia syringe needle of site of puncture hardness.
To achieve these goals, this utility model provides a kind of anesthesia syringe needle, the cylindrical needle body that comprises hollow, wherein, the front end end of described needle body is provided with solid and front end is a conical puncture portion, be symmetrically arranged with an evenly distributed 3-6 medicine outlet hole one on the left and right sides of the front end side wall of described needle body respectively, be symmetrically arranged with an evenly distributed 3-6 medicine outlet hole two on the both sides, front and back of the front end side wall of described needle body respectively, the end, rear end of described needle body is connected with the syringe cylinder connection, and the center of described syringe cylinder connection is provided with the connecting through hole with described needle body internal communication.
Wherein, described medicine outlet hole one and/or described medicine outlet hole two are the angling hole of tilted rearward, and the angle between the centrage of the centrage of described medicine outlet hole one and/or described medicine outlet hole two and described needle body is 30 degree-60 degree.
Wherein, described medicine outlet hole one and described medicine outlet hole two are arranged alternately.Be that medicine outlet hole one and medicine outlet hole two be not on same plane.
Wherein, the front end of described connecting through hole is cylindrical, and the rear end is a truncated cone.
Wherein, the outside of described syringe cylinder connection evenly is provided with the hemispherical non-slip process.
The outstanding advantage of this utility model is: simple in structure, easy to use, owing to be respectively arranged with 3-6 medicine outlet hole one on the left and right side of the front end side wall of needle body, be respectively arranged with 3-6 medicine outlet hole two on the both sides, front and back of the front end side wall of needle body, by the administration simultaneously of a plurality of holes, injection speed is fast, and inject time is short, has shortened anesthesia duration greatly, effectively avoid or reduced the appearance of post-operative complication, medicine outlet hole is difficult for stopping up, and anaesthetic effect is faster and better, and has reduced patient's misery; The front end end of needle body is provided with solid and front end is a conical puncture portion, and site of puncture hardness height is even dura mater puncture anesthesia also can be finished puncture fast; Medicine outlet hole one and medicine outlet hole two are preferably the angling hole of tilted rearward, can better avoid the duct to stop up.
Description of drawings:
Fig. 1 is the overall structure front view of this utility model embodiment.
The specific embodiment:
Design agents mechanism comprised puncture portion 1, needle body 2, medicine outlet hole 1, medicine outlet hole 24, syringe cylinder connection 5, non-slip process 6 and connecting through hole 7 when embodiment of the present utility model implemented.Wherein, the cylindrical needle body 2 that comprises hollow, the front end end of needle body 2 is provided with solid and front end is a conical puncture portion 1, be symmetrically arranged with four evenly distributed medicine outlet holes 1 on the left and right sides of the front end side wall of needle body 2 respectively, be symmetrically arranged with four evenly distributed medicine outlet holes 24 on the both sides, front and back of the front end side wall of needle body 2 respectively, the end, rear end of needle body 2 is connected with syringe cylinder connection 5, and the center of syringe cylinder connection 5 is provided with the connecting through hole 7 with needle body 2 internal communication; Medicine outlet hole 1 and medicine outlet hole 24 are the angling hole of tilted rearward, and the angle between the centrage of the centrage of medicine outlet hole 1 and medicine outlet hole 24 and needle body 2 is 45 degree; Medicine outlet hole 1 and medicine outlet hole 24 are arranged alternately; The front end of connecting through hole 7 is cylindrical, and the rear end is a truncated cone; The outside of syringe cylinder connection 5 evenly is provided with hemispherical non-slip process 6.
