Nasopharyngeal airway insertion is simple, provides good ventilation, maintains hemodynamic stability, is well-tolerated, inexpensive, and readily available, leading to its increasing use in anesthesiology and other departments. However, healthcare professionals should be aware of potential complications such as nausea, vomiting, aspiration, and nasal mucosal injury. While proper placement and fixation of the nasopharyngeal airway can reduce the incidence of nausea, vomiting, and aspiration, nasal mucosal injury is unavoidable.Even when inserted by skilled operators, nasopharyngeal airways can still cause nasal mucosal damage in 4.7% of patients. Furthermore, it cannot be guaranteed that every operator in clinical practice will possess this level of skill, meaning the actual incidence of nasal mucosal damage is likely to be even higher. While nasal mucosal damage is not life-threatening, it increases the risk of infection and reduces patient satisfaction.Therefore, we believe that improvements to nasopharyngeal airways should focus on reducing complications. Improving performance, optimizing structure, reducing complications, and simplifying operation are the future directions for the development of improved nasopharyngeal airways, and the clinical effectiveness of these improved airways still requires further clinical trials for verification.

An oropharyngeal airway is a simple and quick method to maintain airway patency. Placing an oropharyngeal airway can reduce damage to the oral and airway mucosa, prevent tongue prolapse, and facilitate suctioning. Furthermore, the stimulation of the pharynx during oropharyngeal airway placement can activate the vagus nerve, lowering blood pressure and slowing heart rate, which can be beneficial in the treatment of patients with cerebrovascular accidents. Therefore, knowing how to properly insert an oropharyngeal airway is of great importance!

An oropharyngeal airway is a rigid, flattened, tube-shaped artificial airway made of elastic rubber or plastic. It is curved to conform to the shape of the tongue and soft palate, making insertion easy. The oropharyngeal airway commonly used in clinical practice is an oval-shaped, hollow plastic tube with an S-shape. It is easy to use and requires no special instruments, allowing for rapid opening of the patient's airway within seconds. Therefore, it has been widely used in clinical settings and pre-hospital emergency care in recent years.

An oropharyngeal airway, also known as an oropharyngeal tube, is a commonly used artificial airway adjunct. This rigid, flattened tube-shaped artificial airway is typically made of elastic rubber or plastic. Its primary purpose is to maintain the patency of the patient's upper airway in medical emergencies, during anesthesia, or in cases of impaired consciousness.

In thoracic surgery anesthesia and intensive care, the double-lumen endotracheal tube plays a fundamental and irreplaceable role. Simply put, it is the most classic, reliable, and widely used technique for achieving one-lung ventilation and lung isolation, and is the backbone of thoracic surgical anesthesia.An oversized or thickened endotracheal tube increases the risk of postoperative hoarseness, sore throat, and airway damage, and may even cause bronchial rupture. An undersized or thinned endotracheal tube increases ventilation resistance, hinders secretion drainage, and may cause more air to be injected into the cuff, leading to compression of surrounding tissues and local mucosal damage. The tube may also shift deeper into the bronchus, with tidal volume preferentially delivered to the lower lobes, potentially causing tension pneumothorax. The appropriate size matching standard is: the outer diameter of the bronchial lumen of the double-lumen endotracheal tube should be 1-2 mm smaller than the inner diameter of the patient's left main bronchus.

an anesthesia mask itself usually does not contain anesthetic drugs; it is a channel or tool through which anesthetic drugs are delivered to the patient.Standard operating room anesthesia masks are usually empty. They connect to the anesthesia machine as a conduit for delivering anesthetic gases and oxygen. During anesthesia induction (especially in children), they are temporarily filled with anesthetic gases. The anesthetic drug flows from the anesthesia machine's vaporizer and is delivered to the mask via tubing. Inhaled analgesia devices are pre-filled with a gas mixture. They are portable devices, ready to use, for short-term analgesia.Therefore, an anesthesia mask is like a breathing mask; it doesn't store medication, but it's a crucial tool for safely and accurately delivering anesthetic gases to the patient's airway. Anesthesiologists control the anesthesia machine and vaporizer to determine what and how much to administer to the patient through the mask.

balloon uterine stents demonstrate unique advantages in supporting the uterus, preventing recurrent miscarriage, offering simple and safe operation, and allowing for personalized customization. They provide strong protection for women's health, enabling them to face gynecological issues with greater composure and confidence. In the future, with continuous advancements in medical technology, balloon uterine stents are expected to play an even greater role in the field of gynecology, bringing health and happiness to more women.

Oxygen mask and nasal cannula are the two most common oxygen therapy methods in clinical practice, each with its own characteristics. Currently, in routine wards, nasal cannula oxygen therapy is mostly used for oxygen therapy, unless nasal cannula oxygen therapy cannot maintain normal blood oxygen saturation for a long period of time, in which case oxygen mask is chosen.

Urinary catheterization is one of the most basic procedures in clinical nursing, playing a vital role in clinical medicine and nursing. The urinary catheter is the core product used in catheterization to help patients drain urine. Globally, the European and American markets, with their more developed healthcare industries, have a greater demand for urinary catheters, and this demand continues to increase annually. In other regions, the demand for urinary catheters is also constantly increasing due to the aging population. With advancements in catheter manufacturing processes, the urinary catheter industry has enormous future development potential.

Childbirth is a crucial stage in a woman's life, but it is also fraught with challenges and risks. In traditional delivery methods, insufficient cervical dilation often hinders a successful delivery. Disposable cervical dilation balloon catheters are innovative medical devices designed specifically to address this issue.

Paraffin oil is a commonly used lubricant in routine nursing work, especially in current catheterization procedures where most use disposable catheterization kits with pre-installed lubricants. Furthermore, some of these kits don't specify the composition of the lubricant, only vaguely labeling it as lubricant, leading to the misconception that lubricant is simply paraffin oil.

The disposable cervical dilation balloon catheter, as an innovative tool in modern medical technology, plays an increasingly prominent role in the childbirth process. With its unique design and superior performance, this medical device brings expectant mothers a more comfortable and safer childbirth experience.
