Description

Oxygen mask suitable for postoperative use of nasal cavity operation

Technical Field

The invention relates to medical equipment, in particular to an oxygen mask suitable for being used after a nasal cavity operation.

Background

Pituitary tumors are a common benign tumor type in neurosurgery^［1］The proportion of the total disease number of the intracranial tumors is 16.7 percent^［２］. The nasal butterfly approach type becomes the common resection type of the tumor with the advantages of low trauma, quick recovery, low recurrence rate and easy acceptance by patients^［3-4］。

At present, most of the clinical after the nasal endoscope operation still adopt vaseline gauze strips and puffsNasal cavity packing with materials such as swelling sponge, iodophor sliver, silicone tube, and absorbent cotton to prevent complications such as hemorrhage and nasal cavity adhesion^[5-7]. The main purpose of nasal surgery is to improve the quality of life of the patient, however, nasal packing causes more discomfort to the patient^[8]。

Normally, outside air is inhaled into the lung through the nasal cavity, and the nasal cavity has the functions of cleaning, filtering, heating and humidifying the inhaled air, so that smooth and comfortable breathing is kept. Patients who are packed through the nasal cavity change the habit of breathing through the nasal cavity, and the patients cannot adapt to the habit at any time, so that discomfort can be caused. Nursing staff should actively carry out comfortable nursing, a series of discomfort caused after the nasal cavity of the patient is stuffed is improved, the pain of the patient is relieved, and the nursing level of the nursing staff is improved^[9]。

2107 BTS: adult application of oxygen in first-order emergency rooms of medical institutions to write that patients should be given appropriate oxygen inhalation after surgery in order to maintain the patient within an appropriate target saturation range, and for most patients after general anesthesia surgery, it is recommended that the target saturation be set in the range of 94% -98%. Perioperative and post-operative high levels of inhaled oxygen have been proposed to ameliorate post-operative clinical symptoms, including relief from symptoms of post-operative nausea and vomiting, and to reduce the incidence of surgical site infections, based on the earlier Meta assay supporting the hypothesis that increasing oxygen content in tissues within surgical wounds may increase neutrophil killing, thereby reducing infection rates.

Studies by Yurong et al show that patients with nasal cavity stuffiness can tolerate dizziness, headache and dry throat pain after inhaling oxygen, and have less chest distress and tightness and reduced use of analgesic tablets^[10]. The study by the Zhang love et al shows that: after the nasal cavity is filled, patients breathe through the oral cavity, and oxygen deficiency of important visceral organs of the whole body is often caused by the change of a breathing mode, so that the arterial blood oxygen content of the patients is reduced, and the cerebral blood supply is insufficient. Brain cells are very sensitive to ischemia and hypoxia, anaerobic catabolic enzymes are increased, and severe cases can accumulate acidic metabolites in brain, increase vascular permeability and generate brain interstitial edema. In addition, the nasal cavity filler can stimulate nasal cavity mucous membrane to make the patient feel headDizziness, headache, and dizziness. If the oxygen deficiency occurs in the cardiac muscle, the oxygen deficiency of the cardiac muscle can be caused, and the patient can have chest distress and shortness of breath. Emotional instability, mental stress, fear, anxiety in postoperative patients, and also elevation of blood pressure. After the oral nasal catheter inhales oxygen, enough oxygen can be supplied, so that a patient can sleep quietly. The tranquil environment can inhibit cerebral cortex of human body, reduce pain sensitivity, and reduce dosage of analgesic^[11]。

Currently, the oxygen inhalation mode clinically applicable to postoperative patients is as follows:

the double-plug method is characterized in that two tiny nasal plugs are simultaneously arranged in nostrils at two sides, gaps are left around the nasal plugs, air can be breathed simultaneously, a patient feels comfortable, and the oxygen inhalation concentration is not stable enough.

Secondly, an open mask oxygen inhalation method: the mask is placed 1-3 cm away from the mouth and nose of a patient, and is suitable for children and free of discomfort.

The mask is tightly covered on the mouth and nose parts and fixed by an elastic band, is suitable for people with serious oxygen deficiency, has oxygen inhalation concentration of 40-50 percent, is comfortable to feel, and has no mucous membrane stimulation and dry blowing feeling. But has the defects of large oxygen consumption and inconvenient eating and sputum excretion.

And fourthly, the Venturi mask is manufactured according to the Venturi principle. A negative pressure is created around the jet of air, carrying a volume of air into the mask from the open side seams or holes. The oxygen delivery hole has a certain caliber, so that the air sucked from the side seam or the side hole of the mask is 0₂After mixing, the mixture can be kept in a fixed proportion, the size of the side seam of the mask and the driving 02 flow are adjusted, the proportion of air and 02 can be changed, and the size of the proportion determines the inhalation 0₂The concentration is high or low. Patients after nasal cavity surgery mostly use oral nasal catheters for oxygen inhalation, and the oxygen inhalation device designed by the patients after nasal cavity surgery is temporarily not used.

The mask is more reliable for oxygen inhalation than the nasal catheter, and compared with the nasal catheter, the simple mask can avoid nasal complications and increase the comfort. Because the nasal cavity of a patient is filled after the nasal cavity operation, the patient cannot use a nasal cavity double-channel oxygen inhalation mode to supply oxygen, and a conventional oxygen mask is designed for a patient breathing the nasal cavity and does not reserve enough oral cavity breathing space in the oral cavity, so that the conventional oxygen mask is poor in comfort for the patient filled with the nasal cavity, and uncomfortable symptoms such as suffocation feeling of the patient are easily increased.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example one

Referring to fig. 1 to 3, the oxygen mask of the present embodiment includes a mask body 100, where the mask body 100 is respectively provided with a connection hole 101, an oxygen inhalation part 102, a nose support part 103, and a mandible pull part 104, the oxygen inhalation part 102 is provided with a through oxygen inhalation hole 105, a connection pipe head 200 is fixed at the position of the mask body 100 outside the oxygen inhalation hole 105, and the connection pipe head 200 is used for connecting with an oxygen inhalation pipe joint 210, so as to input oxygen into the oxygen inhalation part 102;

the nose support part 103 and the lower jaw support part 104 are respectively used for being attached to the nose bridge and the outer side of the lower jaw of the face; two connecting holes 101 are formed, and the mask body 100 is positioned at the two connecting holes 101 and can be jointed with the face close to the ears. The inner side of the mask body 100 is gradually expanded from an oxygen inhalation part 102 to a connecting hole 101, a nose support part 103 and a mandible dragging part 104 to form a semi-open petal shape, so that the oxygen inhalation part 102 covers the outside of a mouth and nostrils and forms a certain spacing distance, and a sufficient space is provided for a patient to breathe by mouth.

In use, the mask body 100 does not fully conform to the face and there are gaps near the face that intermittently allow the flow of air from the mask interior to be vented.

Preferably, in order to obtain sufficient strength of the oxygen-absorbing part 102, the oxygen-absorbing part 102 is prevented from being deformed and collapsed to affect use. The applicant also arranges a reinforcing rib 300 at the oxygen inhalation part 102 of the mask body 100, and the reinforcing rib 300 is used for supporting the shape of the oxygen inhalation part 102, so as to avoid the deformation and collapse of the oxygen inhalation part 102. The reinforcing ribs 300 are distributed along the curved surface of the oxygen inhalation place 102.

The invention uses the design of a semi-open petal-shaped oxygen mask, and by using the design principle of a Venturi mask, namely the Venturi (Venturi) principle, because the airflow injected into the mask is larger than the highest flow rate and the tidal volume of a patient when the patient inhales (when the 02 flow is more than 4 liters/minute, repeated breathing cannot be generated), the oxygen inhalation concentration is constant, the exhaled air is difficult to stay in the mask because the oxygen continuously flushes the inside of the mask, and the semi-open mask is beneficial to the release of carbon dioxide, so the repeated breathing is basically avoided.

Because nasal cavity is clogged to the patient nasal cavity after the nasal cavity operation, can't use two nasal cavity oxygen tubes, and the patient mostly is oral respiration, and the oxygen mask design of semi-open petal shape gives the sufficient breathing space of patient, alleviates uncomfortable symptoms such as the patient sense of oppression, alleviates patient psychological burden. The oxygen concentration in the local space can be increased, the blood oxygen saturation is increased, and the postoperative oxygen demand of the patient is ensured.

The two connection holes 101 are respectively assembled with both ends of the strap 400, and when in use, the strap 400 is wound around the back of the brain, thereby tightly covering the mask body 100 on the face.

Example two

Referring to fig. 4-6, the height of the face projected from the lips and nostrils of each person varies during actual use, especially when the maxilla of some patients is protrusive. Therefore, the oxygen inhalation part 102 needs to be adjusted according to actual conditions, especially, the inhalation volume of part of patients is large, and a large negative pressure is easily generated on the oxygen inhalation part 102 during inhalation, and at this time, the reinforcing rib may not meet the requirement that the oxygen inhalation part 102 is not deformed, so the applicant makes the following changes:

the mask body 100 is divided into two parts, that is, the oxygen inhalation part 102 and the connection hole 101 respectively correspond to one part, and the two parts are connected by the connection band 110, in this embodiment, the connection band 110 is made of soft elastic material, such as elastic silica gel, and both sides of the connection band 110 are respectively fixed with the corresponding mask body 110 in a sealing connection (gluing or ultrasonic welding), the outer side wall of the oxygen inhalation part 102 is fixed with the adjusting block 130, the mask body 100 on one side of the connection hole 101 is fixed with the inserting pin 120, the inserting pin 120 is provided with the inserting big end 121, and the inserting pin has elasticity, and the inserting big end 121 passes through the support hole 511 of the support strip 510, so that one end of the support strip 510 is fixed on the mask body 100 on one side of the connection hole 101;

the supporting bar 510 has elasticity, the supporting bar 510 of this embodiment is made of elastic plastic, and the other end of the supporting bar 510 passes through the adjusting groove 131 inside the adjusting block 130, and is pressed against the mask body 100 through the pressing block 540 installed in the adjusting groove 131 so as to be relatively fixed to the supporting bar 510 in the length direction, the pressing block 540 is fixed to one end of the connecting rod 520 and is slidably assembled with the adjusting groove 131, the other end of the connecting rod 520 passes through the wave spring 530 and then passes out of the adjusting block 130, and is assembled and fixed with the pull ring 521, the wave spring 530 has elasticity, and two end faces of the wave spring 530 are respectively pressed against the inner end face of the adjusting groove 131 and the pressing block 540, so as to apply the elastic force pressing the supporting bar 510 to the pressing block 540.

When the oxygen inhalation mask is used, the supporting strips are not added, the use is carried out according to the embodiment I, and at the moment, the whole mask body still supports the oxygen inhalation place 102 because the width of the connecting band 110 is not more than 2 cm. Once the oxygen inhalation part 102 needs to be strengthened or the distance between the oxygen inhalation part 102 and the lip needs to be increased, the inserting pin firstly penetrates through the supporting hole 511 at one end of the supporting bar 510, then the pulling ring 521 applies a pulling force to the connecting rod 520 in the axial direction to overcome the extrusion force of the wave spring 530 to the wave spring, so that a gap larger than the thickness of the supporting bar 510 is formed between the pressing block 540 and the mask body, then the supporting bar penetrates through the gap, the pulling ring is released after the support of the oxygen inhalation part 102 is adjusted, and the pressing block presses the supporting bar 510 through the elastic force of the wave spring. In the process, the oxygen inhalation part 102 can be pulled to the direction far away from the connecting band through the elastic force of the connecting band, so that the distance between the inner side of the oxygen inhalation part 102 and the lip part is increased, the connecting band is stretched to store the elastic force in the process, and the elastic force is supported by the supporting bars. The design is very suitable for patients with facial dysmorphism or patients needing special care, such as patients with lip injury, excessive breathing resistance after wearing the mask, temporary incapability of extending the tongue out of the mouth and retracting the tongue into the oral cavity, excessive phlegm and the like. The flexibility is high, and although the cost is also increased, the method is very practical in the environments of ICU, advanced nursing, high-quality nursing and the like.

EXAMPLE III

Referring to fig. 7-8, in the present embodiment, an atomization generator 610 is connected in series at the oxygen inhalation pipe joint 210, and an air inlet of the atomization generator is communicated with pressurized oxygen or air. When in use, atomized medicine is placed in the atomization generator 610, and the air flow can atomize the liquid medicine when passing through, so that medicine mist is formed to realize that the patient still atomizes when inhaling oxygen, and the design can greatly save the treatment time. The aerosol generator of this embodiment may be implemented as a conventional disposable aerosol cup or other device capable of atomizing a liquid.
