[0002] The necessity of first aid practice, the environment in which it occurs, the patients of first aid care and the corresponding nursing measures. First aid care can take place in hospital emergency rooms, pre-hospital or battlefield environments, outpatient departments, and health care institutions. The scope of work of the first aid department is wide, involving multiple disciplines and is very practical. First aid patients can be patients of all ages, and can also be patients with or without a clear medical diagnosis;
[0003] During emergency treatment, some respiratory obstructions and suctioning of the respiratory tract of comatose patients will produce secretions and sputum. Currently, clinical care for the upper respiratory tract is mainly carried out by suctioning the sputum through the mouth and nasal cavity through intubation, but suctioning is inconvenient during prone ventilation. If suctioning is performed on the patient, the connection between the intubation tube and the ventilator needs to be disconnected, and the intubation tube needs to be connected to the suction device. The operation is cumbersome and inconvenient. At the same time, the suction tube is directly connected to the breathing tube and the intubation tube. Although this method is fast to connect, the insertion point is easy to fall off. When the patient is resting, if the breathing tube falls off, the patient will have difficulty breathing and feel uncomfortable. Utility Model Content

One end is fixedly connected with a knob 6. The knob 6 is convenient for the operator to hold and turn. When the knob 6 is turned, the three-way plug valve core 2 can be driven to rotate. The inner wall of the three-way plug valve body 1 has a sealing effect on the three groups of through holes on the outer surface of the three-way plug valve core 2. The operator holds and turns the knob 6. When the knob 6 is turned, the three-way plug valve core 2 is driven, so that the through holes on the outer surface of the three-way plug valve core 2 corresponding to the suction tube 10 are rotated to the inner wall of the three-way plug valve body 1 for sealing, and only the breathing tube 11 is connected to the cannula 9, which is convenient for the patient to breathe. Similarly, if the patient needs to suction sputum, it is only necessary to rotate the through holes on the outer surface of the three-way plug valve core 2 corresponding to the breathing tube 11 to the inner wall of the three-way plug valve body 1 for sealing.
[0021] Among them, the connecting structure 4 includes a spring 7 and a fixing rod 8. One end of the spring 7 is fixedly connected to the inside of the mounting hole on the outer surface of the connecting tube 3. The mounting hole on the outer surface of the connecting tube 3 is convenient for installing the spring 7. The other end of the spring 7 is fixedly connected to the fixing rod 8. The fixing rod 8 extends to the outer surface of the connecting tube 3 through the mounting hole on the outer surface of the connecting tube 3 away from one end of the spring 7. The fixing rod 8 can be retracted and retracted inside the mounting hole on the outer surface of the connecting tube 3. The connecting structure 4 facilitates the connection between the sleeve 5 and the connecting tube 3.
[0022] Among them, three groups of sleeves 5 are sleeved on the outer surface of one end of the connecting tube 3 to open a limiting hole, and the limiting hole plays a role of auxiliary connection. One group of sleeves 5 is fixedly connected to an intubation tube 9 at one end away from the connecting tube 3, one group of sleeves 5 is fixedly connected to a suction tube 10 at one end away from the connecting tube 3, and another group of sleeves 5 is fixedly connected to a breathing tube 11 at one end away from the connecting tube 3. The intubation tube 9 is convenient for implantation in the patient, the suction tube 10 is convenient for connecting to a sputum suction device, so as to facilitate sputum suction for the patient, and the breathing tube 11 is convenient for connecting to a ventilator, so as to facilitate assisting the patient in breathing.
[0023] Among them, the fixing rod 8 is arranged inside the limiting hole on the outer surface of the sleeve 5 at one end away from the spring 7, and the fixing rod 8 can be retracted and retracted inside the limiting hole on the outer surface of the sleeve 5. The fixing rod 8 extends to the inside of the limiting hole on the outer surface of the sleeve 5 to facilitate connecting the sleeve 5 to the outer surface of the connecting tube 3, and then through the cooperation of the sleeve 5 and the connecting structure 4, the three groups of connecting tubes 3 are respectively connected to the intubation tube 9, the suction tube 10 and the breathing tube 11. Under the elastic force of the spring 7, the fixing rod 8 enters the inside of the limiting hole on the outer surface of the sleeve 5 to connect the sleeve 5 to the outer surface of the connecting tube 3.

At the same time, the cannula 9, the suction tube 10 and the other end of the breathing tube 11 are sleeved on the outer surface of the connecting tube 3 through the sleeve 5, so that the limiting hole on the outer surface of the sleeve 5 and the mounting hole on the outer surface of the connecting tube 3 correspond to each other. At the same time, the operator releases the fixing rod 8, and under the elastic force of the spring 7, the fixing rod 8 enters the limiting hole on the outer surface of the sleeve 5, and connects the sleeve 5 to the outer surface of the connecting tube 3. If the cannula 9, the suction tube 10 and the breathing tube 11 need to be replaced, the operator only needs to press the fixing rod 8, and the fixing rod 8 squeezes the spring 7, so that the fixing rod 8 enters the connecting tube 3. When the patient needs to breathe, the operator only needs to hold and turn the knob 6. When the knob 6 is turned, the three-way stopcock valve core 2 is engaged, so that the through hole at the outer surface of the three-way stopcock valve core 2 corresponding to the suction tube 10 is rotated to the inner wall of the three-way stopcock valve body 1 and is sealed, so that only the breathing tube 11 is connected to the cannula 9, which is convenient for the patient to breathe. Similarly, if the patient needs to suction sputum, the operator only needs to hold and turn the knob 6. When the knob 6 is turned, the three-way stopcock valve core 2 is engaged, so that the through hole at the outer surface of the three-way stopcock valve core 2 corresponding to the breathing tube 10 is rotated to the inner wall of the three-way stopcock valve body 1 and is sealed, so that only the suction tube 11 is connected to the cannula 9, which is convenient for the operator to start the suction device to suction sputum for the patient.
