Description

Glottis lower surface anesthesia device

Technical Field

The utility model belongs to the technical field of the medical treatment anesthesia, concretely relates to surface anesthesia device under glottis.

Background

The surface anesthesia can be performed on the vocal cords and the throat cavity when the vocal cord polypectomy is performed, at present, patients under the tracheotomy and the bronchofiberscope examination adopt an invasive subglottic anesthesia method, the patients are very painful, a large amount of anesthetic is needed, and the recovery time can be prolonged. It is necessary to perform non-invasive anesthesia, but no non-invasive apparatus or device for performing subglottic anesthesia is available on the market, and the related apparatus or device is needed for clinical anesthesia work in hospitals.

Disclosure of Invention

The utility model discloses to not being used for the drawback of the non-invasive utensil of the anesthesia of glottis lower surface among the prior art, provide a glottis lower surface anesthesia device, the device can cooperate the visual laryngoscope to realize the non-invasive anesthesia.

The invention aims to be realized by the following technical scheme: the utility model provides a glottis lower surface anesthesia device, is including the pipe fixed strip that has the plasticity, and the crooked setting of pipe fixed strip one end and this end fixing are equipped with outside outstanding epidural catheter, and the fixed syringe that is equipped with of pipe fixed strip other end, injection port fixedly connected with on the syringe along the transfer line of pipe fixed strip setting, the transfer line with epidural catheter intercommunication. Among the above-mentioned scheme, the pipe fixed strip has plasticity, can be crooked the pipe fixed strip according to the demand, adjusts the structure of pipe fixed strip, makes the utility model discloses and visual laryngoscope between agree with more to can realize the noninvasive anesthesia of glottis lower surface.

Preferably, the catheter fixing strip comprises a plastic metal strip, and the plastic metal strip is covered with a plastic layer. The catheter fixing strip arranged in this way is low in cost, and the catheter fixing strip can be broken with a little force to be adjusted.

Preferably, the outer end of the epidural catheter is closed, and a plurality of side holes distributed in a circumferential array are distributed on the peripheral side surface of the epidural catheter. By the arrangement, the anesthetic can be uniformly sprayed towards multiple directions.

Preferably, the injector and the catheter fixing strip, and the infusion tube and the catheter fixing strip are bound and fixed through medical adhesive tapes. The arrangement is convenient for assembling the injector, the catheter fixing strip and the infusion tube together.

Preferably, one end of the catheter fixing strip, which is provided with the syringe, is provided with a bending part, and the bending part is perpendicular to the catheter fixing strip. The bending part can be a stress part for operation.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses the visual laryngoscope of cooperation can realize not having the wound anesthesia, does benefit to the postoperative analgesia and improves the intraoperative anesthesia effect and reduces the quantity of full narcotic, does benefit to the patient and revives fast to accelerate patient's turnover speed between the operation, improve the availability factor between the operation. For critical diseases such as difficult airway patients, aortic dissection operation, shock patients and transcatheter aortic valve implantation, the dosage of anesthetic can be reduced, and the requirement of laryngeal and subglottic surface anesthesia for tracheal intubation can be met.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic cross-sectional view of the catheter retaining strip;

FIG. 3 is an enlarged view of FIG. 1 at A;

the labels in the figure are: 1. the device comprises a catheter fixing strip, 2, a plastic metal strip, 3, a plastic layer, 4, a bending part, 5, an injector, 6, a transfusion tube, 7, a side hole, 8, a medical adhesive tape, 9 and an epidural catheter.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1, fig. 2 and fig. 3, the subglottic anesthesia apparatus comprises a catheter fixing strip 1 with plasticity, wherein the catheter fixing strip 1 comprises a plastic metal strip 2, and the plastic layer 3 covers the outer side of the plastic metal strip 2. 1 one end of pipe fixed strip is equipped with kink 4 perpendicularly, and the crooked setting of 1 other end of pipe fixed strip and this end fixing are equipped with outside outstanding epidural pipe 9, and the fixed syringe 5 that is equipped with of one end of kink 4 of pipe fixed strip 1, injection port position fixedly connected with on the syringe 5 along the transfer line 6 of 1 setting of pipe fixed strip, transfer line 6 epidural pipe 9 intercommunication. The epidural catheter is characterized in that the outer end of the epidural catheter 9 is closed, three side holes 7 distributed in a circumferential array are distributed on the peripheral side face of the epidural catheter 9, and the injector 5 and the catheter fixing strip 1, and the infusion tube 6 and the catheter fixing strip 1 are bound and fixed through medical adhesive tapes 8.

The utility model discloses when using, break off pipe fixed strip 1 earlier, make the crooked end and the visual laryngoscope shape of fixed strip more be close, can anaesthetize after that, carry out intravenous injection general anesthesia medicine earlier to the patient, accomplish induced patient's back of falling asleep, insert visual laryngoscope to patient's oral cavity, under the state of photopic vision glottis, put into the throat with the crooked front end of this device, in the trachea under the glottis, press syringe 5 down, 2% lidocaine 5mL of intratracheal quick injection under larynx and the glottis, withdraw from this device after having annotated, can accomplish throat and glottis lower surface anesthesia, this device is most advanced to have three tiny side opening 7, side opening 7 distributes on transfer line 6 at the interval and is 120 degrees, can spray the local anesthetic to three direction uniformly, thereby realize the non-invasive anesthesia of glottis lower surface. In addition, when the patient is awake, a small amount of local anesthetic such as 1% tetracaine can be sprayed in the oral cavity, after the oral cavity surface anesthesia takes effect, the visual laryngoscope is inserted, and then the device is placed to complete the laryngeal and subglottic surface anesthesia, so that the pain of the patient can be greatly relieved.
