Description

A disposable flushable sputum suction tube

Technical Field

The utility model relates to a sputum suction tube, in particular to a disposable flushable sputum suction tube, belonging to the technical field of medical tools.

Background technique

In case of breathing difficulties, the establishment of an artificial airway by methods such as endotracheal intubation and tracheotomy can effectively ensure the patient's ventilation function and save the patient's life. The establishment of an artificial airway can not only improve the patient's breathing, but also be connected to a ventilator, so that some patients with breathing difficulties can maintain their respiratory function through mechanical ventilation.

In the process of establishing an artificial airway and maintaining the patient's respiratory function, patients, especially critically ill patients, often have airway infections or bleeding, large amounts of thick sputum, which is not cleaned in time and the airflow in and out of the airway can easily form sputum scabs that adhere to the tube wall and cause blockage of the tube, affecting the patient's normal ventilation and leading to adverse consequences.

Sputum suction is the most frequent operation for patients on mechanical ventilation. It is a direct and effective method to effectively maintain the patency of the artificial airway and clear respiratory secretions, especially for patients who need relatively long-term mechanical ventilation. In clinical practice, an airway atomizer is often installed at the joint of the ventilator and the pipeline to achieve the purpose of humidifying the airway and diluting sputum, but it takes a long time to take effect and has limited help in removing sputum crusts on the tube wall. Conventionally, there is also a method of using a syringe to extract the drug solution and drip it directly. The airway drug drip method is used to inject the drug solution into the endotracheal tube to facilitate the flow of the drug solution into the terminal small airways. This method is easy to induce airway infection. It is only used when there are special requirements for the drug onset speed and effect or some diseases require transtracheal administration to achieve the purpose of local treatment. For this reason, a disposable flushable sputum suction tube is proposed.

The utility model is in operation: during use, the product can be completely operated according to the general sputum suction nursing. Taking the right-handed as an example, during operation, the outer package is opened by the negative pressure suction head 102 and the humidification liquid capsule 202 end of the package, and then the right hand wears the medical handpiece, and then the little finger or ring finger of the left hand is inserted into the finger hanging ring 204, and the thumb, index finger and middle finger of the left hand pinch the negative pressure suction head 102 to take the sputum suction tube out of the package.

The negative pressure in 101 first sucks out the sputum in the airway, oral cavity or nasal cavity for subsequent operations, and then the side port plug 43 is moved to open the negative pressure side port 42 to restore the air pressure in the sputum suction tube body 101, and then the humidification liquid capsule 202 is squeezed continuously to squeeze the liquid medicine into the airway for humidification, flushing or dosing operations, and then the negative pressure side port 42 is blocked with the left thumb to make the sputum suction tube body 101 in a negative pressure suction state, and the liquid medicine in the airway, oral cavity or nasal cavity is sucked out to complete the operation, and the airway medicine is injected into the humidification liquid capsule 202 by a syringe through the rubber head 205 provided. For mixing, before injection, the flushing tube 201 is moved to slide into the slot 74 of the limiting mechanism 207, and then the side clamping plate 72 is moved to clamp into the limiting hole 76, so that the outer wall of the flushing tube 201 can be squeezed by the splint 75 in the slot 74 to seal the flushing tube 201, so as to prevent the liquid in the humidifying liquid capsule 202 from entering the interior of the flushing tube 201 in advance when the medicine is injected. When the mixing of the medicine is completed, the side clamping plate 72 can be slid out of the limiting hole 76 by moving the top of the clamping seat 71 to reopen the flushing tube 201.
