Description

Closed suction device

technical field

The utility model relates to a sputum suction device, in particular to a closed sputum suction device. the

Background technique

In critically ill patients, endotracheal intubation is often required for oxygen therapy due to changes or abnormalities in respiratory function. However, endotracheal intubation will hinder the normal output of respiratory sputum, so manual sputum extraction is required after intubation To remove the sputum or secretions from the patient's respiratory tract to maintain the patency of the artificial airway and ensure the normal breathing of the patient, thus making endotracheal suctioning (ETS) the most effective way to manually remove respiratory secretions. main care measures. the

Endotracheal suction can be divided into open suction system and closed suction system according to the implementation method. The main disadvantage of open sputum suction is that during the sputum suction process, the connection between the respirator and the patient and the oxygen supply need to be interrupted, which may easily cause hypoxemia and hypoxia; Suction system suction device, and connect it to the respirator, and then press its negative pressure control valve to implement negative pressure, therefore, the patient can continue to use the respirator during the suction process, which can maintain the necessary positive airway pressure and Therapeutic oxygen concentration. the

Please refer to Fig. 1, a sectional view of an existing closed sputum extraction set, the existing closed sputum extraction set 1', including: a tubular body 100', an oxygen supply manifold 200', a first scraper plate 310', a second scraper 320' and a cleaning manifold 400'. Wherein, the tubular body 100' is open at two ends, and its two opposite open ends are respectively a connecting section 110' and a discharge section 120', and the connecting section 110' is used to connect to a connecting pipe 10', and the The discharge section 120' is used to connect to a collection bag 50'; one end of the oxygen supply manifold 200' communicates with the branch of the tubular body 100' and is between the connecting section 110' and the discharge section 120' , while the other end is connected to an oxygen delivery pipe 20'; The inner partition of 'forms a cleaning chamber 330'; and one end of the cleaning manifold 400' communicates with the discharge section 120' and is between the oxygen supply manifold 200' and the first scraper 310' . the

Based on the above, the existing closed sputum suction sleeve 1' can be sleeved to a sputum suction tube 30', which has a patient end 31' for inserting into the patient's body and extracting the sputum in the patient's body through a negative pressure. waste liquid. When the medical personnel connect the existing airtight sputum extraction sleeve 1' to a sputum extraction tube 30', and after extracting sputum from a patient, the medical personnel will pull the sputum extraction tube 30' to remove the patient's sputum. The affected end 31' is drawn out from the connecting tube 10' to the cleaning cavity 330' for flushing, and when the suction tube 30' passes through the second scraper 320' and the first scraper 310', the patient The waste liquid adhered to the outer surface of the end 31' will be scraped off by the second scraper 320 and the first scraper 310', and then physiological saline will be injected into the cleaning manifold 400' through a water injection pipe 40'. The above components are rinsed in the cleaning chamber 330 ′. the

However, in the process of pulling the sputum suction tube 30' to the cleaning chamber 330' by the medical staff, the negative pressure continues to be in an open state, and the existing closed sputum suction sleeve 1' does not have a fixed A fixed piece at the position of the sputum suction tube 30', therefore, if the medical personnel are not skilled or apply force improperly, the sputum suction tube 30' is separated from the cleaning cavity 330' (ie, the discharge section 120'), which may easily cause A large amount of oxygen is sucked into the collection bag 50' by negative pressure, causing it to expand, resulting in insufficient oxygen supply to the patient and endangering the life of the patient; in addition, if the above-mentioned detachment occurs during the flushing of the sputum suction tube 30' During the process, the flushing water and the patient's sputum will be negatively sucked into the collection bag 50 ′, causing pollution and causing the patient's respiratory tract to be infected. the

Therefore, in view of the fact that the existing closed sputum suction sleeve still has many disadvantages, the designer of the utility model tried his best to research and create, and finally developed and completed a kind of closed sputum suction device of the present utility model, the sputum suction tube There is an anti-exit piece inside the sleeve, which is elastic and can prevent the sputum suction tube from falling into the sputum suction tube sleeve due to excessive pulling by the medical staff, so it can replace the deficiency of the existing closed sputum suction sleeve . the
