    I saw that thing lying on the velvet covered in the box. It was well protected. There was a small mirror attached to the thin metal strip. It was a bit like a dental mirror, much longer than the mouth mirror.  So it¡¯s definitely not a mouth mirror, it¡¯s a laryngoscope.

    It¡¯s just that¡ª¡ª

    "Old antique." Zhang Huayao complained wildly.

    What kind of laryngoscope is the old antique laryngoscope?  It's an indirect laryngoscope.  It is almost the first laryngoscope structure invented. The slender metal strip can connect the small mirror deep into the end of the patient's mouth, allowing the doctor to observe the patient's larynx condition through the mirror image.  At this time, what the doctor sees in the mirror is opposite to the actual internal structure of the patient's body, so it is called indirect laryngoscopy.

    This thing is now mostly used for general examinations in otolaryngology departments. It is very cost-effective to use it to perform general examinations on patients.  An indirect laryngoscopy costs more than ten yuan, which is extremely cheap. Unlike other laryngoscopy examinations, which often cost hundreds.  However, as first aid, this old antique is of little use.

    The doctor needs at least a direct laryngoscope, not an electronic laryngoscope.  One of the biggest functions of direct laryngoscope is to help doctors insert foreign body forceps into the trachea to remove foreign bodies.

    Zhang Huayao picked up the indirect laryngoscope, exhaled, and tried it reluctantly.

    ¡°As smart as a doctor is, it¡¯s hard for a woman to make a meal without rice.

    "I'll look for it again." Lin Liqiong turned around and decided to do what she could.

    Seeing this, the nurse ran with her to find first aid equipment.

    Several doctors on site looked back at the indirect laryngoscope.

    When an otolaryngologist uses an indirect laryngoscope, he or she will wear a forehead reflector on the forehead, which is a concave mirror that can collect light and be equipped with a light source, so that the deeper parts of the patient's mouth can be illuminated more clearly.

    Inside the small box, Zhang Huayao turned over and over again, only to find an indirect laryngoscope and nothing else.  Forget it, let¡¯s use this thing to check the condition of the child¡¯s throat first.

    The conditions were extremely crude, but Zhang Huayao wanted to curse and shouted: "Don't you want to bring an ECG monitor?"

    The child is in such a condition that his heart will stop at any time.  The necessary ECG monitors, breathing bags, and defibrillators should be brought as soon as possible.

    Being yelled at by the boss.  The nurse turned around to pull over the ECG monitor and other rescue equipment.

    "Brother, are you tired? I'll do it for you." Xie Wanying rolled up her sleeves and said.

    Cao Yong was performing chest impact on the child along the way. Don¡¯t underestimate the child¡¯s small body, which does not require much effort to do this.  However, medical operations are all subject to harsh conditions.  Like chest impact, excessive force can easily damage the diaphragm, causing diaphragm rupture, which can endanger the patient's life, such as diaphragmatic hernia. Children are fragile and may accidentally press the short ribs to break the spleen and liver, etc.  These will inevitably require doctors to control their hand strength and operate as accurately as possible.  As a result, the physical demands on doctors are very high.

    "No need." Cao Yong directly refused her offer to replace him, showing that he was not tired.  Moreover, he knew that it was more important for her to help Zhang Huayao determine where the cotton plug was in the child's airway.

    Brother Cao seemed to be very capable. Xie Wanying felt relieved. She turned around and picked up a flashlight to help Teacher Zhang shine into the child's mouth.

    The indirect laryngoscope held by Zhang Huayao was inserted into the child's mouth.

    Such simple conditions test the doctor¡¯s vision too much.  (Remember the website address: www.hlnovel.com
