Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nasal and oral oxygen support device used in ophthalmic surgery. Background Technology

[0002] Nasal and oral oxygen therapy is an important clinical treatment method with wide application and significant effects. It plays an irreplaceable role in improving patients' oxygenation capacity and alleviating hypoxia symptoms. In various disease states, such as respiratory diseases, cardiovascular diseases, and neurological diseases, patients often experience varying degrees of hypoxia. Hypoxia not only affects patients' physiological functions but can also trigger a series of serious complications. Therefore, timely and effective oxygen therapy, providing patients with sufficient oxygen through nasal and oral inhalation, is of great significance for stabilizing their condition and promoting recovery.

[0003] During ophthalmic surgery, when oxygen is administered through the mouth and nose, the connected oxygen delivery tube is attached to the surface of the medical bed, affecting the doctor's range of movement during the operation. If an accident occurs, it will cause irreversible consequences. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an oral and nasal oxygen support device for ophthalmic surgery, including an oxygen mask, a connecting tube fixedly connected to the bottom of the oxygen mask, an oxygen delivery tube fixedly connected inside the connecting tube, a connector fixedly connected to the input end of the oxygen delivery tube, a sliding sleeve sleeved on the surface of the oxygen delivery tube, a connecting platform fixedly connected to the bottom of the sliding sleeve, a fixing column fixedly connected to the inner wall of the connecting platform, a limiting sleeve sleeved on the surface of the fixing column, an arc-shaped clamping plate fixedly connected to the surface of the limiting sleeve, a connecting plate fixedly connected to the bottom of the arc-shaped clamping plate, a connecting locking post sleeved inside the connecting plate, and a locking post locked inside the connecting locking post.

[0005] The above technical solution involves setting a pressing locking post to remove the locking post from the inside of the connecting locking post, then pulling the connecting locking post out from the inside of the two connecting plates. The arc-shaped locking plate is rotated by the limiting sleeve to open the two arc-shaped locking plates and engage the position between the two arc-shaped locking plates with the surface of the fixed column of the surgical frame. After the engagement is completed, the connecting locking post is sleeved inside the connecting plate and fixed with the locking post to connect and fix the oxygen delivery pipe, thus preventing the oxygen delivery pipe from affecting the normal operation of the surgery in the operating room.

[0006] As a further improvement to the above solution, the connecting tube is located at the bottom center of the oxygen mask, and both ends of the connecting tube penetrate the inner wall of the oxygen mask.

[0007] With the above technical solution, both ends of the connecting pipe penetrate the inner wall of the oxygen mask, which facilitates the delivery of oxygen.

[0008] As a further improvement to the above solution, the two ends of the fixing column are fixedly connected to the inner wall of the connecting platform. There are two fixing columns, which are symmetrically and evenly distributed on the inner wall with respect to the bottom center of the connecting platform. There are also two arc-shaped clamping plates, which are respectively set at the bottom of the two limiting sleeves.

[0009] The above technical solution uses two arc-shaped plates to facilitate opening and closing, and subsequent fixing work.

[0010] As a further improvement to the above solution, the connecting pin penetrates through the connecting plate, the pin is located on the outer surface of the connecting plate, and the pin is made of soft plastic.

[0011] The above technical solution uses soft plastic as the material for the retainer, making it easy for medical staff to remove it manually.

[0012] As a further improvement to the above solution, a fixed tube is fixedly connected to the top of the oxygen mask, a filter screen is fixedly connected to the bottom of the oxygen delivery tube, a flexible hose is fixedly connected to the top of the fixed tube, a nasal plug is fixedly connected to the output end of the flexible hose, a one-way valve is provided on the surface of the oxygen mask, and a fixing ring is provided at the rear end of the oxygen mask.

[0013] The above technical solution uses a filter to remove water mist or droplets formed by condensation on the inner wall of the oxygen mask when the patient inhales oxygen, preventing the patient from inhaling them while using the nasal cannula. The flexible tubing allows for easy movement to different positions, facilitating the use of the nasal cannula.

[0014] As a further improvement to the above solution, two fixing tubes are provided, which are symmetrically and evenly distributed on the surface around the top center of the oxygen mask. The two ends of the fixing tubes penetrate the inner wall of the oxygen mask, and the filter screen is located inside the oxygen mask.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a pressing locking post to remove the locking post from the inside of the connecting locking post. The connecting locking post is then pulled out from inside the two connecting plates. A limiting sleeve is used to rotate the arc-shaped locking plates, opening them and engaging them onto the surface of the fixing post of the surgical frame. Once engaged, the connecting locking post is fitted inside the connecting plate and secured, thus connecting and fixing the oxygen delivery pipe and preventing it from interfering with the normal operation of the surgery in the operating room.

[0017] This invention uses a filter to remove water mist or droplets formed by the condensation of exhaled air on the inner wall of the oxygen mask when the patient inhales oxygen, thus preventing the patient from inhaling them when using nasal cannula oxygen therapy. Attached Figure Description
