Urinary catheter with temperature probe is a disposable, multi-lumen medical device that integrates a temperature-sensing element. In addition to standard urinary drainage functions, it enables real-time monitoring of intra-bladder temperature—serving as an indicator of core body temperature—and is primarily used in operating rooms and for critically ill patients in the ICU.

Urinary catheter with temperature-sensing probe is a Class II sterile, single-use medical device. It is designed for use by healthcare professionals on critically ill patients—such as those in the ICU or operating room, patients undergoing or recovering from major surgery, and those suffering from trauma or extensive burns—who require strict core body temperature management.

Chest drainage kits are essential consumables for the emergency treatment of thoracic conditions and postoperative management in thoracic surgery; they serve as life-saving tools within trauma care systems and are indispensable for the interventional treatment of pleural cavity disorders. These kits can be broadly categorized into thoracentesis drainage kits and closed-system chest drainage kits. Thoracentesis drainage kits focus on the instruments required for puncture and catheter placement and typically include a drainage bag. Closed-system chest drainage kits feature an integrated water-seal system; primarily used for pneumothorax and hemopneumothorax, they represent the most commonly used type in clinical practice.

Chest drainage kit (disposable closed chest drainage kit) is a core invasive consumable used in emergency medicine and thoracic surgery; it is an essential instrument for managing pleural cavity pathologies and holds an irreplaceable role in emergency departments, thoracic surgery units, ICUs, and trauma surgery.

Double-lumen endobronchial tube is the gold-standard device for achieving one-lung ventilation in adult thoracic anesthesia, offering irreplaceable value in scenarios requiring strict lung isolation to prevent secretions or blood from the affected lung from contaminating the healthy lung. However, due to limitations regarding airway anatomy, it is clinically complemented by bronchial blockers; the choice between them depends on the patient's airway conditions and the type of surgery.

Standard endotracheal tubes are fundamental, general-purpose instruments for airway management, whereas double-lumen endobronchial tubes are specialized gold standard devices for thoracic anesthesia; they are not interchangeable. Both are cuffed, artificial intratracheal airways that can be connected to a ventilator for positive-pressure ventilation and the prevention of aspiration. The standard single-lumen endotracheal tube is widely used for the vast majority of surgeries, emergency resuscitation, and critical respiratory support; it provides ventilation to both lungs without enabling lung isolation and serves as the foundation of airway management. In contrast, the double-lumen endobronchial tube is primarily used for thoracic surgeries requiring single-lung ventilation and lung isolation, as well as for critical unilateral pulmonary conditions; it has a limited scope of application, is unsuitable for long-term placement, and cannot replace the standard endotracheal tube for routine airway management.

Both PVC laryngeal masks and silicone laryngeal masks are supraglottic airway devices (SADs) with identical clinical functions: they are positioned in the pharynx to seal the esophagus and facilitate ventilation during general anesthesia or emergency airway management. While most are disposable, some silicone versions can be sterilized and reused.

There are two mainstream manufacturing methods for laryngeal mask cuff connectors: injection molding (producing hard or semi-rigid connectors, which is the dominant method) and, in a minority of older models, integral molding via PVC dip molding. Typically, the connector and the cuff balloon are bonded together during a subsequent assembly step, though in a few cases, they are integrally molded. Medical-grade soft PVC must meet ISO 10993 biocompatibility standards and possess thermal stability to prevent the release of HCl due to thermal decomposition at high temperatures.

The solution for a endotracheal tubes production line comprises seven key stages: project planning, cleanroom construction, utility system setup, equipment delivery and installation, IQ/OQ validation, trial production and process verification, and finally, compliance certification and mass production. This process strictly adheres to the established sequence for constructing sterile medical device production lines—establishing the clean environment first and installing production equipment last—as reversing this order could create serious risks of contamination later on.

Endotracheal tubes are classified as Class II sterile, non-active medical devices. The construction of the endotracheal tube production line comprises six major modules: cleanroom infrastructure, process equipment, utility systems, personnel systems, regulatory compliance, and environmental protection and safety.

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.
