DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Figure 1-Figure 3 : Example The present invention relates to an oropharyngeal ventilation catheter for anesthesia, which is particularly suitable for keeping the patient's airway unobstructed during surgical anesthesia to ensure the effective supply of anesthetic gas. The following is a specific embodiment of the oropharyngeal ventilation catheter for anesthesia: 1. Structural composition The oropharyngeal ventilation catheter for anesthesia in this embodiment is mainly composed of a catheter mask 1 and a catheter body including a transverse tube 21. The catheter mask 1 is designed to fit the shape of the patient's oropharynx to ensure sealing while providing sufficient ventilation space. The catheter body is responsible for connecting the supply source of anesthetic gas and guiding the gas to the patient's respiratory tract.
[0015] 2. Catheter structure Reference part: The reference part is composed of a transverse tube 21, an adapter 22 and a longitudinal tube 23. The transverse tube 21 and the longitudinal tube 23 are detachably connected through the adapter 22. This design facilitates adjustment of the angle and length of the catheter according to the specific conditions of the patient and improves the flexibility of use. An inlet check valve 6 is installed on the longitudinal tube 23 to ensure that the anesthetic gas can only enter the catheter in one direction to prevent gas backflow.
[0016] Extension: The extension is connected to the end of the transverse tube 21 away from the adapter 22, and includes a tee tube 24. The air inlet end of the tee tube 24 is detachably connected to the transverse tube 21 through threaded matching. This connection method not only ensures the firmness of the connection, but also facilitates disassembly and cleaning. The air outlet end of the tee tube 24 is connected to two groups of interchangeable tubes 25, each group of interchangeable tubes 25 is connected to the transverse adjustment tube 27 through a bend 26, and finally a nasal tube 28 and a mouthpiece tube 29 are installed respectively. This design allows doctors to choose ventilation through the nasal cavity or oral cavity according to the needs of the patient.
[0017] 3. Catheter-mask design Fixed gauze 5: A fixed gauze 5 is installed on the inner side of the catheter mask 1 to increase the fit between the mask and the patient's oropharynx and reduce irritation to the patient's oropharynx. The nasal tube 28 and the mouth tube 29 are elastically connected to the fixed gauze 5 to ensure the stability of the catheter during the patient's breathing.
[0018] Exhalation one-way valve 3: An air vent is provided on the catheter mask 1, and an exhalation one-way valve 3 is installed in the air vent to allow the patient to exhale gas smoothly while preventing external gas from entering the catheter.
[0019] Strap 4: A strap 4 is also installed on the catheter mask 1 to fix the catheter mask on the patient's head to ensure that it will not fall off during use.
[0020] 4. Usage Preparation stage: According to the specific conditions of the patient, select the appropriate catheter length and angle, connect the transverse tube 21 and the longitudinal tube 23 through the adapter 22, and install the air intake check valve 6.
[0021] Install the catheter mask: Place the catheter mask 1 on the patient's oropharynx, making sure that the fixing gauze 5 fits tightly against the patient's oropharynx. Use the strap 4 to secure the catheter mask to the patient's head.
[0022] Connecting the nasal tube / mouthpiece tube: According to the doctor's instructions, select a suitable nasal tube 28 or mouthpiece tube 29, and connect it to the three-way tube 24 through the lateral adjustment tube 27 and the elbow 26.
[0023] Start ventilation: Connect the supply source of anesthetic gas to the inlet check valve 6 of the longitudinal tube 23 and start ventilation. The doctor can control the supply of anesthetic gas by adjusting the ventilation volume of the nasal tube 28 and the mouthpiece tube 29 according to the patient's breathing condition and surgical needs.
[0024] End and cleaning: After the operation, disconnect the supply source of anesthetic gas, disassemble the catheter mask 1 and the catheter body, and clean and disinfect each component for next use.
[0025] Through the description of the above embodiments, the structure, working principle and use method of the oropharyngeal ventilation catheter for anesthesia can be clearly understood. The catheter is reasonably designed, easy to operate, safe and reliable, and can meet the needs of patient airway management during surgical anesthesia.
