TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field, concretely relates to an oxygen inhalation tube with adjustable length of nasal plug. BACKGROUND
[0002] An oxygen inhalation tube is a common medical device that is used to deliver oxygen, regulate its concentration, and maintain its flow rate. It is commonly used in various medical scenarios, including emergency care, surgery, treatment of hypoxemia, or other situations where additional oxygen support is required. The tube is typically made of soft plastic material and has one end connected to an oxygen source and the other end connected to the patient's nose or mouth. It allows the delivery of oxygen from the source to the patient's respiratory tract for oxygen therapy. The core components of an oxygen inhalation tube usually include an oxygen inlet, an oxygen hose, and a nasal plug. The oxygen inlet is located at the front end of the oxygen hose and is used to connect to the oxygen source to ensure smooth flow of oxygen into the hose. The nasal plug is usually installed at the end of the oxygen hose and is used to insert into the patient's nostrils, allowing the oxygen in the hose to flow directly into the patient's nasal cavity.
[0003] However, in the prior art, the length of the nasal plug of the oxygen inhalation tube is mostly fixed and cannot be adjusted. For example, the utility model patent with application number CN2015201551976 discloses an adjustable oxygen inhalation tube, which includes a catheter, a nasal plug fixing sleeve, a nasal plug, a connecting joint, and a catheter telescopic fixing sleeve, an ear hook, and a head. The catheter telescopic fixing sleeve has two sleeves on the catheter, located on both sides of the nasal plug fixing sleeve. The ear hook has two parts, connected to the two catheter telescopic fixing sleeves. One end of the catheter is sealed by the head, and the other end is connected to the connecting joint. The nasal plug used in this utility model is of fixed length, which makes it impossible to adjust the actual length of the nasal plug according to the specific situation of the patient's nasal cavity when using the oxygen inhalation tube. This means that personalized services cannot be provided to patients to improve their comfort and reduce the overall user satisfaction of the product. In particular, when a surgical patient inhales oxygen, the expelled oxygen will rush towards the surgeon's eyes, affecting the surgeon's operation. Therefore, the present application aims to provide a new type of oxygen inhalation tube with adjustable length of nasal plug tube, which can improve the comfort of patients, especially surgical patients, by extending the nasal plug tube beyond the narrow part of the nasal cavity, reducing the amount of expelled oxygen, and improving the comfort of the surgeon. UTILITY MODEL CONTENT
[0004] The utility model aims to overcome the above-mentioned shortcomings of the prior art and provide an oxygen inhalation tube with adjustable length of nasal plug.
[0005] The utility model discloses a technical scheme of a nasal obstruction pipe length adjustable oxygen inhalation pipe, which comprises an air inlet interface, a hose, a nasal obstruction mounting seat and a nasal obstruction pipe.
[0006] Further, the length of the telescopic part of the nasal obstruction pipe can be adjusted.
[0007] Further, the telescopic part of the nasal obstruction pipe is in the form of a bellows.
[0008] Further, the support part is in the form of a cylinder (pipe).
[0009] Further, the support part is in the form of a truncated cone, and the diameter of the end of the support part away from the hose is smaller than the diameter of the other end.
[0010] Further, the telescopic part of the nasal obstruction pipe is directly connected to the nasal obstruction mounting seat.
[0011] Further, there are two support parts, and the central axes of the two support parts are arranged in parallel.
[0012] Further, the length of the nasal obstruction pipe is greater than the length of the support part, so that one side end of the fixed part of the nasal obstruction pipe can always protrude outside the support part.
[0013] The oxygen inhalation tube has the advantages that the nose plug pipe is arranged in a telescopic structure, so that the length of the nose plug pipe can be adjusted, and the comfort of use of the patient is improved; the telescopic part of the nose plug pipe is always located in the supporting part, the telescopic part can be supported by the supporting part, the nose plug pipe is prevented from being bent, and the consistency of the two nose plug pipes can be ensured in the product with the two nose plug pipes. In addition, the oxygen inhalation tube can be elongated to exceed the narrow part of the nasal cavity, so that the discharged oxygen is reduced, the impact force of the airflow on the eyes of the doctor is reduced, and the comfort of the doctor is improved. In summary, the oxygen inhalation tube can be in the contracted state when used by ordinary patients, and the telescopic part is in the extended state when used by the surgical patient, so that the discharge amount of oxygen when the patient exhales is reduced, and the comfort of the surgical doctor is improved.
