A structure of the needle special for local anaesthesia includes a needle head, a needle rod, a needle seat, a medicament infusion pipe, an adjustable switch, a connecting soft pipe and an anaesthetic bottle, one end of the needle rod connects with the needle head, the other end connects with the infusion pipe through the needle seat, the infusion pipe is equipped with the adjustable switch, a middle part of the infusion pipe connects with the transition connecting soft pipe, the other end of the infusion pipe connects with the anaesthetic bottle. Compared with the prior art, the needle special for local anaesthesia has characteristics of reasonable design, simple structure, convenient operation, wide application and low cost.
Description
(1) technical field
This utility model relates to a kind of medical apparatus and instruments, the anesthetic needle of specifically a kind of hospital local anesthesia special use.
(2) background technology
As everyone knows, hospital needs to anaesthetize before undergoing surgery to patient, especially in the time of will carrying out operation below the hypogastric region, many employing lumbar anesthesias or the such local anesthesia of epidural anesthesia, the process of local anesthesia is by anesthetic needle puncture, injecting anesthetic medicine, or be sprayed on mucomembranous surface with aerosol apparatus, and spread upon mucomembranous surface with cotton balls, fill with cotton balls or sliver.For reaching perfect anesthesia, often need multiple dosing, general 2～3 times, be separated by at every turn and local anaesthetics injected in 5 minutes in the tissue of operative region, retardance teleneuron and reach anesthetic action.If but operating time is long,, must change local anesthesia into general anesthesia because of the restriction of local anesthesia time, and the general anesthesia meeting brings many complication to patient, causes drug toxicity reaction, stimulates body tissue, and property of flaccid muscles is poor, is not easy to the carrying out of performing the operation.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, the local anesthesia special needle that provides a kind of hospital to use
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of local anesthesia special needle, structure comprises syringe needle, shank, needle stand, grug transportation tube, by-pass cock, connection flexible pipe, anaesthetic bottle, one termination of shank has syringe needle, the other end links to each other with tube for transfusion by needle stand, a by-pass cock is arranged on tube for transfusion, the place connects the connection flexible pipe of a transition in the middle of the tube for transfusion, and the other end of tube for transfusion is connected on the anaesthetic bottle.
Above-mentioned local anesthesia special needle, its shank shape be arc, make according to people's oral cavity shape.
Local anesthesia special needle of the present utility model compared with prior art, the beneficial effect that is produced is:
1) simple in structure, easy to use.Quite convenient when local anesthesia special needle of the present utility model is used, only need when medicine loses anaesthetic effect, open by-pass cock and proceed the anaesthetic injection and get final product;
2) anaesthetic effect is obvious.When the doctor performed the operation to patient, this utility model can prolong anesthesia duration, strengthened property of flaccid muscles, helped the carrying out of performing the operation;
3) have wide range of applications.This utility model not only can be applied to the hypogastric region operation, because the shape of shank is basic and the oral cavity shape is coincide, anaesthetizes so can also be used for operation on oral cavity;
4) increase work efficiency.The simple using method of this utility model helps improving medical worker's anesthesia efficient, and outpatients mental state is produced positive role, helps the carrying out of performing the operation.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, syringe needle, 2, shank, 3, needle stand, 4, grug transportation tube, 5, by-pass cock, 6, connect flexible pipe, 7, the anaesthetic bottle.
(5) specific embodiment
Below in conjunction with explaining below accompanying drawing 1 a kind of local anesthesia special needle work of the present utility model.
As shown in Figure 1, a kind of local anesthesia special needle of the present utility model, its structure comprises syringe needle 1, shank 2, needle stand 3, grug transportation tube 4, by-pass cock 5, connects flexible pipe 6, anaesthetic bottle 7, one termination of shank 2 has syringe needle 1, the other end links to each other with tube for transfusion 4 by needle stand 3, a by-pass cock 2 is arranged on tube for transfusion 4, and the place connects the connection flexible pipe 6 of a transition in the middle of the tube for transfusion 4, and the other end of tube for transfusion 4 is connected on the anaesthetic bottle 7.
Above-mentioned shank 2 is curved, and the shape in its shape and oral cavity matches.
When carrying out the following surgery anesthesia of hypogastric region to patient, injection anaesthetic after puncturing with syringe needle 1 is earlier used immobilization with adhesive tape then, and behind certain hour, patient anaesthetizes drug effect and alleviates, and opens by-pass cock 5, proceeds the anaesthetic injection, finishes until operation.
A kind of its processing and fabricating of local anesthesia special needle of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
