Problems solved by technology

However, the existing breathing masks are relatively large in volume, and usually cover the patient's mouth and nose completely. Although the mouth and nose can be ventilated to avoid apnea, the masks are relatively large in size, and are usually fixed on the head by elastic bands, etc. It is difficult to ensure that the mask will not be displaced during sleep. At the same time, due to the large size, it will also cause inconvenience to sleep and may cause great discomfort.

[0031] like figure 1 As shown, a nasal mask for OSA patients comprises a bracket 1, and the two ends of the bracket 1 are respectively fixedly connected with a nose piece 2, and the nose piece 2 is provided with a ventilation tube 3, the inside of the nose piece 2 and the bracket 1 are hollow, and the ventilation tube 3 It communicates with the inside of the nose piece 2 and the bracket 1, the bracket 1 is made of flexible material, and the inside of the bracket 1 is provided with a shaped iron wire. The middle part of the support 1 is provided with a connecting through hole, and the connecting through hole runs through the upper and lower surfaces of the support 1 . The connection through hole is connected with the air delivery pipe 7 , and the air delivery pipe 7 is arranged on the upper surface side of the support 1 , and the front end of the air delivery pipe 7 passes through the connection through hole and is connected with the gasket 5 . Air holes 8 are evenly distribut...

Embodiment 2

[0037] The preparation method of crotonate-grafted starch is as follows,

[0038] Step 1: Weigh a portion of starch, take an appropriate amount of water as a solvent, adjust the pH of the solution to 4.7, add an appropriate amount of isopropanol to prepare a suspension with a starch mass fraction of 37%, and stir for 30 minutes;

[0039] Step 2: Add NaOH to the solution according to the starch:NaOH mass ratio of 1:0.05, heat up to 30°C, stir at a constant temperature for 30 minutes, and slowly drop allyl chloride into the solution according to the NaOH:allyl chloride molar ratio of 1:1.2 , heated up to 50°C, and stirred at constant temperature for 24h;

[0040]Step 3: Filtration, taking the solid and redispersing it in a distilled water-ethanol solution with a volume ratio of 18:82, adjusting the pH to 7 with acetic acid, washing with an appropriate amount of distilled water after suction filtration, and drying to obtain allyl etherified starch;

[0041] Step 4: Take a portio...

[0044] Pseudoephedrine derivatives The synthesis method is as follows:

[0045]

[0046] Reagents and conditions: (Ia-i) periodate, chromium trioxide, glucose isomerase, acetonitrile, room temperature; (Ia-ii) sodium hydride, ethanol, α-amylase, room temperature; (Ia-iii) hydroboration Sodium, DMF, heated to reflux; (Ia-iv) sodium ethoxide, DMF, heated to reflux.

[0047] Weigh 1.71g of 2-(5-chloro-2-methylphenyl)ethan-1-ol into a 150mL three-neck flask, measure 20mL of acetonitrile, stir and dissolve at room temperature, add 0.4g of glucose isomerase , 0.2g of chromium trioxide, continue to stir at room temperature for 10min, weigh 2.28g of periodic acid and dissolve in 10mL of acetonitrile, gradually and slowly dropwise add to the reaction system, and continue to react at room temperature for 36h. After the reaction of Ia-1 was completed, the reaction was stopped, and the solvent was concentrated under reduced pressure. Through column chromatography, the developer was ...

Abstract

The invention discloses a nasal mask for an OSA patient, and belongs to the field of medical apparatuses and instruments. The nasal mask for the OSA patient comprises a support. The two ends of the support are fixedly connected with nasal plates respectively, a breather pipe is arranged on each nasal plate, the nasal plates and the support are hollow, the breather pipes and the nasal plates are communicated with the interior of the support, the support is made from flexible materials, and a sizing iron wire is arranged inside the support. The nasal mask for the OSA patient has the advantages that the structure is novel, the size of the mask is greatly reduced, the comfortable sleep is obtained while it is ensured that a patient can keep good mouth and nose circular air, and meanwhile it is ensured that the mask will not deflect when the patient turns over during sleeping.

Description

technical field [0001] The invention relates to a medical device, in particular to a nasal mask for OAS patients. Background technique [0002] OSA (Obstructive Sleep Apnea) patients will experience mouth and nasal airflow cessation for 10 seconds or more during sleep, accompanied by symptoms such as decreased blood oxygen saturation, usually, the number of attacks per night reaches 30 The above can cause many serious complications, leading to daytime sleepiness in patients, often falling asleep unconsciously during conversations, memory loss, inability to concentrate, decreased work efficiency, and changes in mood and behavior. Restlessness, dreaminess, enuresis, impotence, morning headache, etc. The prior art uses nasal masks, masks, etc. to cover the face of the patient when he falls asleep, and continuously ventilates and supplies oxygen to him during sleep, thereby ensuring the circulation of his mouth and nasal airflow during his sleep and avoiding apnea. However, th...
