Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example (b): as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, the utility model relates to a disposable oropharynx surface anesthesia injector, which comprises an injector 4 and a main pipe 2, wherein one end of the main pipe 2 is communicated with an atomization nozzle 1, the other end of the main pipe 2 is communicated with a first connecting pipe 3, the first connecting pipe 3 is connected with a liquid outlet of the injector 4, a position of the injector 4 at the liquid outlet is fixedly provided with a limit block 5, the side of the limit block 5 is provided with a limit groove 9, a plastic core bar 7 is fixedly arranged on the limit block 5 and at the center of the limit groove 9, the side of the main pipe 2 is fixedly provided with an auxiliary pipe 6, one end of the auxiliary pipe 6 is communicated with a second connecting pipe 8, the plastic core bar 7 is arranged in the auxiliary pipe 6, the second connecting pipe 8 is inserted into the limit groove 9, the main pipe 2 is provided with a plurality, a plurality of second slots 11 are formed in the top and the bottom of the inner wall of the main pipe 2, and the auxiliary pipe 6 is vertical to the main pipe.

The shapeable core rod 7 is made of an austenitic stainless steel wire, so that the shapeable core rod 7 can be bent and can maintain the bent state.

Wherein, main pipe 2 and auxiliary pipe 6 are made by PVC for main pipe 2 and auxiliary pipe 6 can be buckled, and the tip of auxiliary pipe 6 seals the setting.

The first slot 10 and the second slot 11 are both arc-shaped slots of 1/4 circles, the cross sections of the first slot 10 and the second slot 11 are both conical, and when the main pipe 2 and the auxiliary pipe 6 are bent, the arrangement of the first slot 10 and the second slot 11 reduces the probability that the main pipe 2 and the auxiliary pipe 6 are shriveled due to bending.

The length of the auxiliary pipe 6 is smaller than that of the main pipe 2, and the part close to the atomizing nozzle 1 needs to spray only the mouth, so that the length of the auxiliary pipe 6 is smaller than that of the main pipe 2, and the blocking of the mouth by the auxiliary pipe 6 is reduced to a certain extent.

When the oropharynx surface anesthesia operation is needed, a doctor firstly bends the main pipe 2 according to the radian of the patient's mouth, after the adjustment is finished, the inconvenience of the radian of the main pipe 2 can be ensured due to the arranged plastic core rod 7, and at the moment, the doctor can perform the oropharynx surface anesthesia operation on the patient;

after the oropharynx surface anesthesia operation that finishes, the doctor can pull down first connecting pipe 3 from syringe 4, pull down second connecting pipe 8 from spacing groove 9, and then realize pulling down and be responsible for 2 and auxiliary pipe 6, when carrying out oropharynx surface anesthesia operation next time again, the more new person in charge 2 and auxiliary pipe 6 of changing, 2 and auxiliary pipe 6 are responsible for in this disposable use of having realized, guaranteed simultaneously that plastic core bar 7 need not be along with disposable, the effectual cost that reduces long-term the use.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
