I joined the big family of Haiye Medical at the end of July. As a new employee, I have just finished a one-month training period.
During this period, the company not only focused on imparting professional product knowledge, but also focused on cultivating our ability to think independently. During the product training, we were encouraged to operate the product ourselves, understand the assembly and disassembly of the product, and encouraged to learn how to intubate.
In this training, I felt the dual improvement of skills and literacy. As a new employee, it is very important to understand the basic structure and working principle of the laryngoscope and its application in different medical scenarios.
Next, I would like to share some knowledge I learned during laryngoscope intubation training:
1. Preparation before using video intubation laryngoscope:
Before starting the operation, make sure all equipment are ready.
Patient preparation:
Make sure the patient lie on his back with his head slightly tilted back, and adopt the "sniffing position", that is, the earlobe is level with the sternum, to facilitate airway exposure.
Equipment preparation:
Check the video laryngoscope: confirm the cleanliness and normal working state of the display screen, light source, and blades. Choose the appropriate laryngoscope blade size according to the patient's condition.
Intubation tool preparation: including disposable endotracheal tube (size suitable for the patient), guide wire (if necessary), etc.
2 .Operation steps of video intubation laryngoscope:
Insert the video laryngoscope:
Hold the video laryngoscope in your hand, gently insert the blades into the patient's mouth, and slowly slide it down along the patient's tongue. The movement should be gentle to avoid causing the patient's gag reflex or damaging the oral mucosa.
Locate the glottis:
Once the blades enters the oropharyngeal cavity, observe the patient's laryngeal structure through the display screen. Adjust the position of the blades so that the glottis can be clearly seen. If the field of view is unclear, could slightly adjust the angle of the blades or the patient's head posture.
3. Insert the tube of video intubation laryngoscope:
After confirming that the glottis is clearly visible, insert the endotracheal tube into the mouth along the blades slot of the Haiye video laryngoscope, and observe the process of the tube entering the glottis through the display screen. Make sure that the tube enters the trachea smoothly and does not enter the esophagus by mistake.
4. Inflate the balloon of video intubation laryngoscope:
After the endotracheal tube is correctly positioned, use the balloon syringe to inject an appropriate amount of air into the balloon of the endotracheal tube to inflate it in the trachea, ensuring that the endotracheal tube is fixed and the airway is closed.
5. Connect the equipment of video intubation laryngoscope:
After intubation is completed, connect the endotracheal tube to the ventilator or anesthesia machine to check the patency of the airway.
6. Fix the tube of video intubation laryngoscope:
Be careful not to affect the comfort of the patient's mouth during the fixation process.
During intubation, be patient and stable, and move gently and steadily, avoiding impatience or excessive force to avoid damaging the patient's mouth or throat.
Laryngoscope product training is a systematic process that covers basic knowledge, product selection, operating skills, maintenance, and regulatory requirements. Through repeated practice of intubation, not only can technical skills be improved, but also the needs of end customers can be better understood in real operations.
I know that as a newcomer, I still have a lot to learn and improve, but I also believe that in this team full of love and professionalism, I can continue to grow, gradually master more technology and knowledge, and fully practice the Haiye spirit.
