Laryngeal mask is a core device for supraglottic airway management and serves as indispensable, standardized equipment in modern anesthesia, emergency medicine, and critical care. Both Gel-like laryngeal masks and standard inflatable silicone laryngeal masks are classified as second-generation supraglottic airway devices (SADs); they are used to establish non-invasive ventilation pathways—serving as alternatives to tracheal intubation—during general anesthesia, pre-hospital emergency care, and cardiopulmonary resuscitation.

Gel-like laryngeal mask is a supraglottic airway management device designed to replace tracheal intubation and traditional inflatable silicone laryngeal masks; it is used to establish a secure airway during anesthesia, emergency care, and resuscitation.

Negative pressure drainage bag—also known as a negative-pressure drainage bulb or a disposable negative-pressure drainage device—is a Class II sterile, disposable medical consumable. It is a closed drainage system that generates internal negative-pressure suction through the manual squeezing of the bulb to actively evacuate blood, exudate, and pus from a wound, distinguishing it from standard drainage bags that rely on gravity flow.

Negative Pressure drainage bag is an essential, standardized consumable in surgical procedures and a core tool in modern wound care. It not only replaces traditional gravity drainage to become the mainstream drainage method but also significantly reduces the nursing workload, enables quantitative monitoring, enhances patient comfort, and facilitates rapid recovery.

Medical-grade silicone is the gold-standard material for high-end medical consumables and the preferred choice for applications requiring high safety and high added value. PVC is the most widely used general-purpose material for medical consumables and serves as the cornerstone of the global disposable medical supplies market. Together, they constitute the two pillars of medical polymers; with distinct roles and an inability to replace one another, they collectively account for over 70% of the medical plastics market.

Anesthesia masks play a pivotal role in the medical field and consist of two main components: the mask shell and the air cushion. The rigid shell is typically made of transparent hard plastic (such as PP or PC), while the soft cushion that contacts the face—also known as the sealing cushion—is the component where material composition varies most significantly.

Manual resuscitator is the first-choice device for immediate ventilation in emergency cases involving cardiac arrest, asphyxia, or coma, helping to secure critical time for subsequent life-saving interventions; it is a standard piece of emergency medical equipment. As the most fundamental, practical, and widely used manual respiratory resuscitation device, it plays a vital role across the entire continuum of care—including pre-hospital treatment, in-hospital care, and patient transport—serving as an indispensable tool for basic life support within the emergency medical system.

Manual resuscitator—also known as a simple resuscitator or bag-valve-mask—is a portable, manually operated emergency device for artificial ventilation. It consists of an elastic bag, a face mask, a one-way valve, a reservoir bag, and an oxygen inlet. Requiring no power source, it can be operated by hand to provide assisted breathing to patients suffering from hypoxia or respiratory arrest.

Wound drainage kits serve as the first line of defense in wound care; they are indispensable medical consumables spanning the entire continuum of care—from the management of surgical wounds and routine trauma treatment to in-hospital therapy and home-based rehabilitation. These kits not only ensure safety during clinical surgeries and streamline wound care procedures but also play a pivotal role in preventing wound-related disabilities, avoiding prolonged recovery times, and averting the worsening of medical conditions.

Wound drainage kits are essential disposable medical consumables in the healthcare industry; they facilitate the removal of pathological fluid accumulation from the wound site, prevent the spread of infection, allow for direct monitoring of the patient's condition, and reduce the risk of serious postoperative complications.

The CPR mask is a standard, essential component of modern emergency medical systems for safe rescue breathing, a core barrier for infection control, and a tool mandatorily recommended by global guidelines.

Gel-like TPE laryngeal masks (such as the i-gel) are second-generation supraglottic airway devices; their primary function is to rapidly establish a non-invasive, sealed artificial airway for use in anesthetic ventilation, emergency resuscitation, and difficult airway management.
