Why do nurses wear masks when giving injections to patients?
Wearing a mask for clinical nurses is the simplest and most effective isolation method to effectively prevent pathogenic microorganisms from entering the body through the respiratory tract, which can achieve the standard prevention function, not only preventing diseases from spreading from patients to nurses, but also preventing diseases from spreading from nurses to patients. Because of the specific working environment, nurses have to contact all kinds of patients every day, and there are many opportunities to be infected by pathogens. During the epidemic period, the nosocomial infection rate of nurses is very high, which is due to patients coughing, sneezing and talking, which makes blood, body fluids, tissues and other substances become aerosols and enter the air. Aerosol contains various pathogenic factors, which enter clinical nurses through respiratory tract and cause various diseases. With the change of epidemic situation and disease spectrum of infectious diseases, new infectious diseases appear constantly, nurses are in a high-risk working environment for a long time, and the risk of occupational exposure is increasing. Wearing a mask is very important to prevent and control hospital infection. Medical masks can prevent splashing of body fluids, blood and secretions, and protect medical staff and patients by blocking some bacteria, viruses and harmful gases.
Therefore, nurses wear medical masks when giving injections to patients to prevent cross-infection in hospitals, rather than nurses like to wear them.
How to wear a medical mask correctly?
When wearing a medical surgical mask, it should be unfolded with the nose clip facing outwards. The mask must completely cover the nose, mouth and chin. The upper belt is tied in the middle of the back of the head, and the lower belt is tied behind the neck. Press the fingertips of both hands on the nose clip, and press the fingers down from the middle position and gradually move to both sides. Shape the nose clip according to the bridge of the nose, and adjust the tightness of the strap to make the mask fit closely with the face.
Medical surgical masks and medical protective masks can only be used once, and cannot be hung in front of the neck or put into the pocket for repeated use, and the continuous use time shall not exceed 4 to 6 hours. In the process of wearing a medical mask, it is necessary to avoid pressing the center of the mask by hand to prevent pathogens from infiltrating into the inner layer of the mask and artificially increase the chance of pathogen infection.
In a word, nurses don't like wearing masks, and they have to wear them, because wearing medical masks can avoid cross-infection to a certain extent, which is good for patients and themselves. Medical masks should be worn correctly, otherwise they will lose their meaning.
