1, the eyes inadvertently into the sand eyes are the most delicate organs of the human body, can not tolerate any foreign body. If the foreign body is not removed in time, blinking will cause pain, inflammation, ulceration and even blindness. When a foreign body enters your eyes, it is most important not to rub your eyes vigorously or wipe them with a dry tissue or towel. The right thing to do is to open your eyes, have a partner help you open your eyelids, and carefully examine the whites of your eyes (conjunctiva), lower eyelids, and cornea. If the foreign body is in the eyelid or white part of the eye, use a tissue dipped in a little pure water to gently wipe away the foreign body (at home, it is best to use a cotton swab dipped in a little antibiotic eye drops to wipe away the foreign body); if the foreign body is in the upper eyelid, at the cornea, or embedded deeper, you must go to the hospital in time. 2, fish bones stuck in the throat fish bones stuck in the throat, you should immediately stop eating, open your mouth wide to make the “ah” sound, so that the family with the help of light or flashlight, see clearly where the fish bones, and then clip out with tweezers. If the fish bone is not found, the fish bone may be stuck in the deeper part of the throat and should be seen by a hospital. After the fish bone is removed, there will still be a foreign body feeling in the throat for a short period of time, which is due to local mucosal abrasions and should not be minded. Many people like to use the method of swallowing large dry rice balls to deal with fish bones stuck in the throat. This method may be effective for small fish bones, but it is not effective for slightly larger fish bones, and sometimes it will be deeper due to squeezing and stabbing. Some people think that once the fish bone is stuck in the throat, they can swallow edible vinegar several times in small amount to make the fish bone dissolve. In fact, vinegar stays in the throat for a short time, it is impossible to dissolve the fish bones. 3, small flying insects into the ear canal After the small flying insects suddenly into the ear canal, do not use your fingers or other things to pull it out, so as to avoid the small flying insects drill deeper and deeper, in case of drilling through the eardrum, can cause hearing loss. The correct way is to go to a dark place and shine a flashlight on the ear canal, using the insect’s phototropism to draw out the flying insects with light. You can also put a few drops of cooking oil in the ear canal to make the wings of the flying insects wet and unable to open, and then use an ear spoon to pull the insects out of the ear canal. If the above methods do not work, you should go to the hospital immediately. 4, choking on food If the patient can still speak or cough, indicating that the airway is not completely blocked, try to let him cough out better; if the patient is conscious, but can not cough up the choked food, the Heimlich maneuver can be used, that is, upward pressure along the patient’s upper abdomen quickly, by the impact of airflow to squeeze out the food out of the airway; if the patient has called out, his mouth should be immediately wrenched open, with the index finger If the patient does not cry out, he should immediately open his mouth and use his index finger to stick to the side of the corner of his mouth and reach into the deep part of the mouth to do the hook sweeping action until the food is removed. If the above attempts do not work, the patient should be sent to the hospital immediately.
