Abstract

FIELD: medical equipment. SUBSTANCE: invention relates to medical equipment for performing puncture-dilatation tracheostomy. Provided is a device for monitoring the deflation of a tracheostomy tube cuff during a puncture-dilatation tracheostomy after checking the tightness of the tracheostomy tube cuff during deflation, which is a parallelepiped containing a funnel with a smooth inner wall, configured to apply a medical lubricant, and a straight cylindrical channel. The width of the funnel is related to the height of the funnel in a ratio of 1:2. The funnel narrows towards the base of the device for 60% of the device height and forms a straight cylindrical channel 40% of the device height, reaching the base of the device. Wherein the device is configured to press the tracheostomy tube cuff against the outer wall of the tracheostomy tube after inserting the distal end of the inflated tracheostomy tube cuff into the device funnel with the wall of the inflated tracheostomy tube cuff abutting the inner wall of the device funnel. EFFECT: ability to give the deflated tracheostomy tube cuff the most advantageous shape, maximally facilitating its rapid and atraumatic insertion into the formed tracheostomy opening to improve the results of performing a puncture-dilatation tracheostomy. 1 cl, 4 dwg

A device for monitoring the deflation of a tracheostomy tube cuff during a puncture-dilation tracheostomy after checking the tightness of the tracheostomy tube cuff during the deflation process, which is a parallelepiped containing a funnel with a smooth inner wall made with the possibility of applying a medical lubricant, and a straight cylindrical channel, wherein the width of the funnel is related to the height of the funnel in a ratio of 1:2; the funnel narrows towards the base of the device by a length of 60% of the height of the device and forms a straight cylindrical channel with a length of 40% of the height of the device, reaching the base of the device; wherein the device is made with the possibility of pressing the cuff of the tracheostomy tube against the outer wall of the tracheostomy tube after inserting the distal end of the inflated cuff of the tracheostomy tube into the funnel of the device with the wall of the inflated cuff of the tracheostomy tube resting against the inner wall of the funnel of the device.

Description

The present invention relates to medical equipment, and more specifically to additional equipment for a kit for installing a tracheostomy tube, and can be used to perform a puncture-dilation tracheostomy operation. Tracheostomy is a common procedure in medicine and is performed on patients requiring long-term mechanical ventilation (MV). During this procedure, a special tracheostomy tube is inserted into the trachea through an opening created in the anterior surface of the neck. A ventilator circuit is connected to the proximal end of the tracheostomy tube. A special cuff is located at the distal end of the tracheostomy tube. When inflated, this cuff seals the breathing circuit, thereby obstructing the trachea. This ensures that inhalation and exhalation during MV occur only through the lumen of the tracheostomy tube, preventing oral contents from penetrating down into the trachea and bronchi. The inflated cuff also serves as one of the mechanisms for securing the tracheostomy tube within the tracheal lumen. Tracheostomy tubes are sterilely packaged in individual containers during manufacture, with the cuffs deflated. Immediately before inserting a tracheostomy tube into the patient's trachea, a trial inflation of the tracheostomy tube cuff should be performed to rule out manufacturing defects (Fig. 1). After this, the tracheostomy tube cuff is deflated as much as possible; it is pressed against the wall of the tracheostomy tube, but it assumes a free-form shape (Fig. 2). Tracheostomy techniques for creating a tracheostomy opening on the anterior surface of the neck can be either open surgical or percutaneous, using a technique known as a puncture-dilatation tracheostomy (PDT). PDT offers several distinct advantages over open surgical tracheostomy: it does not require patient transport to the operating room and is performed directly at the patient's bedside in the intensive care unit (ICU). Two methods are most commonly used for PDT. The first method, according to the Griggs method, involves using a special Howard-Kelly clamp to create a tracheostomy opening. The second method, according to the Ciglia method, utilizes a special curved "rhinoceros"-type dilator. The Ciglia method creates conditions for optimal formation of a tracheostomy opening that perfectly matches the diameter of the tracheostomy tube. This ensures maximum sealing and rapid formation of a channel in the soft tissues of the neck for the tracheostomy tube, minimizing the risk of surgical complications such as bleeding or infection. However, precisely the precise correspondence between the diameters of the formed opening and the tube creates certain surgical difficulties, including potential technical challenges during insertion of the tracheostomy tube into the trachea. Even a fully deflated tracheostomy tube cuff, after a preliminary integrity check, increases the actual outer diameter of the tracheostomy tube by several millimeters (Figure 2), which impedes smooth and atraumatic insertion of a well-lubricated tracheostomy tube into the trachea. This also increases the risk of damaging the tracheostomy tube cuff, necessitating immediate replacement of the entire tracheostomy tube. Thus, tracheostomy tube preparation, in terms of ensuring the correct shape of the deflated tracheostomy tube cuff, is an important aspect of successful and safe PDT, especially when performed using the Sigley technique. Devices such as an "automatic intermittent tracheostomy tube cuff inflator-deflate" (AUTOMATIC INTERMITTENT TRACHEOTOMY TUBE CUFF INFLATOR-DEFLATOR, patent US3529596A, United States) are known. These devices are connected to a ventilator circuit, and the pressure supplied to the tracheostomy tube cuff automatically varies depending on the respiratory phase. During inhalation, the pressure is higher, and during exhalation, the pressure is lower. This ensures maximum atraumatic and safe long-term placement of the tracheostomy tube in the patient's trachea, reduces soft tissue trauma and trophic disorders, while maintaining the tightness of the breathing circuit. A disadvantage of this device is the inability to completely remove air from the tracheostomy tube cuff, as well as the inability to shape the tracheostomy tube cuff to fit the tracheostomy tube as tightly as possible during deflating. The closest devices to the claimed device are the "LMA Cuff Deflator," which are available for various types of oropharyngeal airways (laryngeal mask airways). An inflated laryngeal mask airway is placed between two specially shaped surfaces. As the laryngeal mask airway deflates, these surfaces are pressed together, completely deflating the laryngeal mask airway and allowing it to assume a more comfortable shape for easy insertion into the patient's oral cavity. A drawback of this device is its inability to effectively deflate the tracheostomy tube cuff. The essence of the claimed invention is that a device (product) is proposed that enables one operator to
