Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a closed wireless visual self-cleaning sputum suction tube. Background Art

[0002] In many clinical situations, patients cannot clear respiratory secretions on their own, such as patients under surgical anesthesia, patients with severe pneumonia, comatose patients, tracheotomy patients, and elderly patients with difficulty coughing up sputum. They need artificial suction to keep the airway open and prevent hypoxia, suffocation, and even death. Suction is a very important and commonly used treatment technique in clinical practice. Existing suction tubes include: 1. Traditional blind-insertion suction tubes, typified by polyvinyl chloride (PVC) single-lumen suction tubes and closed suction tubes; 2. Cable-type visual suction tubes: A miniature camera is integrated at the front end of the suction tube, and visual operation is achieved through a cable-connected external display device, such as a video laryngoscope suction tube, which needs to be connected to a host cable and is a wired suction tube with a light source and a camera; 3. Anti-clogging suction tubes: Blockage is reduced by improving the smoothness of the inner wall of the suction channel or adding a filter, but manual flushing or replacement of parts is required, such as a suction tube with a detachable flushing head; For example, a closed sputum suction tube in "CN220656057U" relates to the field of sputum suction tools. The invention provides a closed sputum suction tube that is easy to operate and helps prevent flushing water from dripping into the patient's airway. The closed sputum suction tube includes a head sleeve, a sputum suction tube body, a flushing tube and a control valve; the head sleeve is provided with a sleeve hole and a valve core hole; the control valve includes a valve core, the valve core includes a valve core inner section and a valve core outer section, the valve core inner section cooperates with the valve core hole, the valve core outer section is exposed to the head sleeve, the valve core inner section has a through hole arranged in the same direction as the sleeve hole, the valve core has a flushing liquid hole, the flushing liquid hole extends from the valve core outer section to the valve core inner section, the wall surface of the valve core hole closes the flushing liquid hole, the flushing tube is connected to the valve core outer section and communicates with the flushing liquid hole; after the valve core is rotated 90°, the flushing liquid hole faces rearward, and the wall surface of the valve core hole closes the through hole; the sputum suction tube body is coaxially arranged with the sleeve hole, the front end of the sputum suction tube body is located behind the control valve, and the sputum suction tube body can move forward through the through hole; However, in the existing technology, in clinical respiratory secretion clearance operations, traditional suction tubes are mostly blind-insertion designs, making it difficult to intuitively judge the position of the tube tip and the area where secretions accumulate. Operators can only rely on experience to estimate the depth, which can easily cause mucosal damage or incomplete suction. In addition, conventional flexible or rigid suction tubes need to be connected to external negative pressure equipment through long hoses, and suction control mostly relies on manual thumb hole adjustment, which not only increases the complexity of operation but also cannot provide real-time feedback on changes in the tube. Once the lens or lumen in the tube is covered with viscous sputum, suction must be interrupted for manual cleaning, seriously affecting surgical efficiency and patient safety. Currently, the visual suction devices on the market are often connected to external monitors using wired optical fibers or cables. Although they can provide a certain degree of visual guidance, the exposed data cables limit the freedom of operation and increase the risk of cross-infection. In addition, it is difficult to achieve real-time cleaning and anti-fog and anti-sticking of the endoscope lens during continuous suctioning. At the same time, most products fail to effectively integrate the cleaning channel, wireless transmission and automatic anti-blocking functions, and cannot meet the urgent demand for a "visualization, wireless, and self-cleaning" three-in-one solution in intensive care and surgical anesthesia scenarios. Summary of the Invention

[0009] Furthermore, the annular fill light is distributed in a ring around the miniature camera. The annular fill light has a light emitting angle of 120°-160° and a color temperature adjustment range of 2700–6500K, which is used to ensure clear visualization in different mucus environments.

[0010] Furthermore, the end face of the tracheal interface is provided with a fixed tube, one end of the film protective sleeve is assembled and connected to the end face of the fixed tube, and the end face of the sputum suction tube body is slidably arranged in the fixed tube.

[0011] Furthermore, the isolation valve is a one-way closed structure, and the isolation valve is located at one end of the suction tube body close to the suction catheter connector, which is used to ensure that the gas-liquid backflow is automatically blocked after the tube is removed.
