Description

A new controllable automatic airway surface anesthesia nebulizer

technical field

The invention relates to the technical field of a novel controllable automatic airway surface anesthesia sprayer, in particular to a novel controllable automatic airway surface anesthesia sprayer.

Background technique

At present, the surface anesthesia of the airway mucosa is performed using a classic throat sprayer to spray surface anesthetics. Since the sprayer can only be sprayed into the pharyngeal cavity through the outer mouth of the nasal cavity and the oral cavity, the range of airway surface anesthesia that can be implemented is very limited. It is located in the nasal cavity oropharynx, and requires multiple operations by medical staff. At the same time, because the sprayed surface anesthetic is in the shape of a fine water column, it is easy to cause uneven distribution of the surface anesthetic, which seriously affects the anesthesia effect, and easily causes severe coughing, which affects breathing. safety of interventional therapy. For those with abnormal anatomy of the oral cavity and maxillofacial region, topical anesthesia is even more difficult to implement.

The operator only needs to prepare the medicine, connect the device, connect the oxygen source, adjust the pressure, At the same time as the endoscope is inserted, through the treatment hole of the bronchoscope, insert the steel wire-reinforced spray tube with a spherical spray head at the front end. The spherical spray head is at the front end of the treatment hole. Due to the steady pressure applied to the surface anesthetic bottle, press the control switch, according to If necessary, it can be continuously sprayed or intermittently sprayed. As the bronchoscope advances, the topical anesthetic is evenly sprayed toward the front. The topical anesthetic can be evenly distributed in the airway mucosa and has an anesthetic effect on the surface of the airway. Due to the uniform distribution of surface anesthetics, the use of drugs is reduced, and the occurrence of toxic reactions of anesthetics is effectively reduced. The operator can complete the manual injection by the assistant by using a controllable automatic spray. And the patient is more comfortable.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1, the present invention provides a kind of technical scheme: a kind of novel controllable automatic airway surface anesthesia nebulizer, its composition comprises: automatic spray control module 12 and surface anesthesia medicine box 5, described automatic spray control module 12 The top is fixedly connected to the surface anesthetic drug input port 8 and the spray pipe interface 11, and the top of the surface anesthetic drug box 5 is provided with a dosing port 4, and the surface anesthetic drug input port 8 is connected to the surface anesthetic drug delivery tube 7 through the surface anesthetic drug delivery tube 7. The surface anesthetic output port 6 on the top of the medicine box 5 is connected, the bottom of the topical anesthetic output port 6 is connected to the catheter 17, and the spray tube interface 11 is connected to the spherical spray head 15 through the spray tube 13. The top of the surface anesthesia kit 5 is connected to the oxygen connection pipe 3, the automatic spray control module 12 is equipped with a spray switch 9, the described dosing port 4 is fastened with a sealing cover 18, and the oxygen connection pipe 3 is The decompression meter 2 is fixedly installed, the end of the decompression meter 2 is connected to the oxygen source 1, the inside of the wall of the spray pipe 13 has a reinforced steel wire 14, and the injection port 16 is opened on the described automatic spray control module 12, A one-way valve 10 is installed on the described injection port 16 .

working principle:

Connect the decompression gauge 2 to the oxygen source in the closed state;

Add the surface anesthetic to the surface anesthetic box 5 through the dosing port 4

Connect the decompression gauge 2 and the air source interface of the surface anesthetic box 5 with the oxygen connecting pipe 3;

Connect the surface anesthetic drug box output port 6 with the surface anesthetic drug input port 8 of the automatic spray control module 12 with the surface anesthetic drug delivery tube 7;

The surface anesthetic drug input port 8 is connected to the spray switch 9 by a conduit, the spray switch 9 is connected to the spray pipe interface 11 by a conduit, and the one-way injection valve 10 is connected to the spray pipe interface 11 by a conduit;

Connect the input end of the pipe wall steel wire reinforced spray pipe 13 to the spray pipe interface 11 of the automatic spray control module 12;

Insert the spherical spray head 15 of the tube wall steel wire reinforced spray tube 13 through the treatment hole of the bronchoscope, so that the spherical spray head 15 just exposes the front end of the bronchoscope;

Open the decompression gauge and adjust the output pressure;

According to the clinical operation, the bronchoscope starts to enter the airway, press the drug spray switch 9 intermittently or continuously, and under the push of the air pressure, the topical anesthetic passes through the topical anesthetic delivery tube 7-topic anesthetic input port 8-medicine spray switch 9-spray tube Interface 11—spray tube 13—reaches the spherical spray head 15, and is sprayed in a spherical shape under the action of air pressure. The surface anesthetic can be evenly sprayed on the airway mucosa at the front end of the bronchoscope to anesthetize the surface mucosa of the front end trachea;

One-way medicine injection valve, if necessary, can spray vascular mucous membrane contraction medicine, thrombin, normal saline and other therapeutic medicines to the operation field through this valve.

Through the automatic airway surface spray anesthesia, the airway can achieve a good surface anesthesia effect. Using pneumatic spray technology, the surface anesthetic is sprayed through the dense fine spray holes of the spherical nozzle to perform airway surface anesthesia. The operator only needs to prepare the medicine, connect the device, connect the oxygen source, adjust the pressure, and then At the same time as the bronchoscope is inserted, through the treatment hole of the bronchoscope, insert the steel wire-reinforced spray tube with a spherical spray head at the front end. If necessary, it can be continuously sprayed or intermittently sprayed. As the bronchoscope advances, the topical anesthetic is evenly sprayed toward the front end. Because the spray head is spherical, the topical anesthetic can be evenly distributed on the airway mucosa at the front end, and has an anesthetic effect on the airway surface. Solved the existing surface anesthesia of the airway. When the bronchoscope enters, the range of surface anesthesia using the existing laryngeal sprayer is very limited and the anesthesia is uneven. Pharyngeal cavity, due to the sensitivity of the larynx, severe coughing and glottis closure will occur. At this time, the assistant injects the topical anesthetic with a syringe through the bronchoscope treatment hole intermittently. Because most of the topical anesthetic is stored in the In the space of the treatment hole of the bronchoscope, it is necessary to repeatedly inject air into the treatment hole to push out the surface anesthetic in the treatment hole, which is cumbersome to operate and the anesthesia speed is slow, and the surface anesthetic flows out through the treatment hole in the form of a small water column, which cannot be evenly distributed The surface of the airway leads to unbalanced anesthesia of the front end airway, and patients are prone to cause cough reflex, which can cause damage to the airway mucosa, and repeated injections may easily lead to overdose of surface anesthetics and toxic reactions. Simultaneously, by using the present invention, the operation can be completed independently, which saves human resources.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
