Abstract
The utility model relates to the technical field of auxiliary medical instruments, in particular to an anesthetic needle. The anesthetic needle comprises an injection needle cylinder and a syringe needle. The syringe needle comprises a semispherical stop block and a needle body, wherein the needle body is fixedly arranged in the center of the plane of the stop block, the center of the needle body is provided with a needle body internal cavity, the center of the stop block is provided with a through hole, one end of the through hole is communicated with the needle body internal cavity, and the other end of the through hole is fixedly communicated with the injection needle cylinder through a plastic hose. According to the anesthetic needle, the syringe needle is connected with an injector through the hose, the syringe needle can be fixed at the position needing to be injected through the stop block, the stability of the anesthesia process is improved, the anesthetic needle is simple in structure and convenient to use, and the unnecessary pain of majority of patients is lowered.
Description
Technical field
This utility model relates to medical auxiliary apparatus technical field, especially a kind of anesthetic needle.
Background technology
Anesthesia is preoperative necessary preparation, when anaesthetizing to patient, anaesthetist uses the syringe with syringe needle repeatedly to puncture to carry out anaesthetic injection, because syringe and the anesthetic needle of ordinary syringe is one, use Shi doctor's hand easily to rock, cause the position of puncture firmly uneven, easily to patient, cause unnecessary misery, and anaesthetist's operation is also comparatively required great effort.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome syringe and the anesthetic needle of ordinary syringe in prior art, be one, use Shi doctor's hand easily to rock, cause the position of puncture firmly uneven, easily to patient, cause unnecessary painful problem, this utility model provides a kind of anesthetic needle, hose connection by using between syringe needle and syringe, and syringe needle can be fixed on syringe needle by stopper the position that needs injection, improved the stability of anaesthesia process, simple in structure, easy to use, reduced the unnecessary misery of extensive patients.
This utility model solves the technical scheme that its technical problem adopts: a kind of anesthetic needle, comprise syringe and syringe needle, described syringe needle comprises hemispherical stopper and needle body, described needle body is fixedly installed on the center of stopper plane, described needle body center is provided with needle lumen, described stopper center is provided with through hole, and through hole one end is connected with needle lumen, and the other end is fixedly communicated with syringe cylinder by plastic flexible pipe.
In order to make the more stable of anesthetics injection, described needle lumen internal diameter equates with described through hole internal diameter.
Using stopper fixedly during anesthetic needle, in order to reduce the frictional force between anesthetic needle and patient skin, in described stopper plane, be provided with one deck silicone rubber pad.
As preferably, the thickness of described silicone rubber pad is 2-4mm.
As preferably, described plastic flexible pipe is PVC flexible pipe.
The beneficial effects of the utility model are: a kind of anesthetic needle that this utility model provides, hose connection by using between syringe needle and syringe, and syringe needle can be fixed on syringe needle by stopper the position that needs injection, improved the stability of anaesthesia process, simple in structure, easy to use, reduced the unnecessary misery of extensive patients.
