Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of video laryngoscopes, and particularly relates to a video laryngoscope for anesthesia intubation. Background Art
[0002] Anesthesia intubation is to insert a soft ventilation tube into the trachea during general anesthesia, also called tracheal intubation, that is, to insert a tube into the trachea, so as to manage the airway. During general anesthesia, the patient is completely asleep, and in order to ensure the muscle relaxation effect at the surgical site, muscle relaxant drugs will be used. After using muscle relaxant drugs, the patient's spontaneous breathing will disappear, which is equivalent to being unable to breathe by oneself. Therefore, an artificial airway needs to be established and connected to a ventilator for breathing. And anesthesia intubation is an effective artificial airway.
[0003] When intubating a patient during anesthesia, it is often necessary to use a video laryngoscope for assisted operation. Insert the end of the video laryngoscope with a camera into the patient's throat, open the patient's throat and then insert the tracheal tube. However, currently, the insertion order of the tracheal tube and the video laryngoscope is sequential, that is, it is necessary to first insert the video laryngoscope, and then insert the tracheal tube under the guidance of the laryngoscope. During the insertion, the angle of the laryngoscope needs to be adjusted multiple times, and then the position of the tracheal tube needs to be adjusted, which causes more friction to the patient's throat, is easy to scratch the patient's throat, and affects the insertion efficiency. In addition, since the tracheal tube is relatively soft, it is easy to bend during insertion, and the insertion operation is inconvenient.
[0004] Therefore, a video laryngoscope for anesthesia intubation with stable insertion, high insertion efficiency and convenient operation is needed. Content of the Utility Model
[0005] In order to solve the above problems, the utility model provides a video laryngoscope for anesthesia intubation, which has the characteristics of convenient operation and strong practicability.
[0006] To achieve the above purpose, the utility model provides the following specific solutions:
[0007] A video laryngoscope for anesthesia intubation includes a display screen. A grip is installed at the bottom of the display screen. A manipulation arc plate is fixedly connected to one side of the bottom of the grip. Guide arc grooves are symmetrically formed on both side walls of the manipulation arc plate. A tracheal tube is inserted into the inner side of the guide arc grooves. A shielding strip is fixedly arranged on the edge of the inner wall of the guide arc grooves, and the shielding strip is located outside the tracheal tube.
[0008] As a preferred technical solution of the video laryngoscope for anesthesia intubation of the utility model, clamping grooves are symmetrically formed on the inner wall of the guide arc grooves. A support arc plate is inserted into the inner side of the clamping grooves. One end of the support arc plate is provided with an insertion rod, and the support arc plate is located on one side of the tracheal tube.
[0009] As a preferred technical solution of the visual laryngoscope for anesthesia intubation of the utility model, a friction strip is fixedly provided on the edge of the outer wall of the supporting arc plate, and the friction strip is located on the inner side of the card slot.
[0010] As a preferred technical solution of a visual laryngoscope for anesthesia intubation of the utility model, a pointed cone end is fixedly provided at one end of the plug-in rod, and the pointed cone end is plugged into the inner side of the supporting arc plate.
[0011] As an optimal technical solution of the visual laryngoscope for anesthesia intubation of the utility model, the friction strip and the shielding strip are both made of flexible materials.
[0012] As a preferred technical solution of a visual laryngoscope for anesthesia intubation of the utility model, an extended pressing plate is fixedly provided at an edge of one end of the operating arc plate, and a camera is provided in the middle of one end of the operating arc plate.
[0013] As a preferred technical solution of a visual laryngoscope for anesthesia intubation of the utility model, one end of the guiding arc groove passes through the handle.
[0014] As a preferred technical solution of the visual laryngoscope for anesthesia intubation of the utility model, a switch is provided on the side wall of the display screen.
[0015] Compared with the existing technology, the utility model has the following beneficial effects:
[0016] The utility model provides an operation arc plate, which is used as the lower end part of the visual laryngoscope, and has guide arc grooves symmetrically arranged on the two side walls thereof. When the tracheal intubation is performed on the patient during anesthesia, the tracheal intubation tube is clamped to the inner side of the guide arc grooves on the side walls of the visual laryngoscope. As the visual laryngoscope is inserted into the throat of the patient, the tracheal intubation tube can be synchronously driven to be inserted into the throat of the patient. When the angle of the visual laryngoscope is adjusted, the tracheal intubation tube can also be synchronously driven to be adjusted. The operation is convenient, the friction on the throat of the patient during intubation can be reduced, the plug-in efficiency can be improved, the bending of the soft tracheal intubation tube during insertion can be avoided, and the plug-in stability can be improved.
[0017] And by inserting and setting a supporting arc plate on the inner side of the guiding arc groove, the supporting arc plate is located on one side of the tracheal cannula after the tracheal cannula is engaged. After the tracheal cannula is adjusted by adjusting the visual laryngoscope and the tracheal cannula at the same time, the operator can insert one end of the plug-in rod into the inner side of the supporting arc plate. As the plug-in rod is inserted, the supporting arc plate is propped up, so that the supporting arc plate pushes the tracheal cannula on one side, thereby making the tracheal cannula detach from the guiding arc groove. Then the operator can pull out the visual laryngoscope, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
