[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The purpose of the utility model is to provide a nasal mask suitable for reducing nasal air leakage under non-invasive assisted ventilation, so as to solve the problems existing in the above-mentioned prior art, reduce nasal air leakage, maintain a stable air flow, and thus improve the effect of non-invasive ventilation used by newborns in clinical practice.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Embodiment 1

[0030] The present embodiment provides a nasal mask suitable for reducing nasal air leakage under non-invasive assisted ventilation, comprising a mask body 1, a connecting layer 2 and a contact layer 3, wherein the connecting layer 2 is connected to the mask body 1, the connecting layer 2 is made of a flexible material, the connecting layer 2 and the mask body 1 form an oxygen supply chamber, the connecting layer 2 has a breathing port 7, and the patient can absorb oxygen in the oxygen supply chamber through the breathing port 7; the connecting layer 2 is a triangular structure; the contact layer 3 is arranged on a side of the connecting layer 2 away from the mask body 1, the contact layer 3 can contact the patient's skin, and the contact layer 3 is made of artificial leather; the contact layer 3 comprises a first contact strip 4 and a second contact strip 5, the number of the first contact strips 4 is two groups, the two first contact strips 4 are symmetrically arranged at two adjacent sides of the connecting layer 2, and can contact the patient's nose wings, the second contact strip 5 extends from the bottom edge of the connecting layer 2 in a direction away from the first contact strip 4, and can contact the patient's skin between the upper lip and the nose.

[0031] The utility model is suitable for reducing nasal air leakage under non-invasive assisted ventilation, and is particularly suitable for neonatal patients. A contact layer 3 is provided on the side of the flexible connection layer 2 away from the mask body 1. The contact layer 3 is made of artificial leather material and contacts the patient's skin to reduce the pressure injury of the nasal mask on the patient's nose. Specifically, the contact layer 3 includes a first contact strip 4 and a second contact strip 5. The first contact strip 4 contacts the patient's nose wing, and the second contact strip 5 extends in a direction away from the oxygen supply chamber and is located outside the projection area of ​​the mask body 1. The second contact strip 5 contacts the skin between the patient's upper lip and nose, so that the nasal mask fits the patient's skin more closely, reduces air leakage, and maintains a stable airflow, thereby improving the effect of non-invasive ventilation for neonates in clinical practice. The nasal mask in the prior art is generally made of rigid material, which causes the nasal mask to fit poorly to the human skin and easily causes air leakage. The utility model arranges two first contact strips 4 at the nose wings of the nasal mask to contact the patient's nose wings, and at the same time adds a second contact strip 5 between the upper lip and the nose. The second contact strip 5 extends beyond the projection area of ​​the mask body 1, thereby increasing the contact degree between the nasal mask and the patient's skin, making the nasal mask fit more closely to the skin of the nose wings, both sides of the nose, and between the upper lip and the nose, effectively reducing air leakage and maintaining a stable airflow rate. The contact layer 3 is made of artificial leather to avoid damage to the patient to the greatest extent and protect the patient's skin.

[0032] It should also be emphasized that a fixing layer 6 is provided on the side of the first contact strip 4 and the second contact strip 5 away from the connecting layer 2. The fixing layer 6 is made of a sticky material. The fixing layer 6 can be adhered to the patient's skin. The fixing layer 6 is used to adhere the nasal mask to the patient's skin, thereby further improving the fit between the nasal mask and the patient's skin, avoiding air leakage, ensuring a stable air flow, and enhancing the effect of non-invasive ventilation for newborns in clinical practice.

[0033] In this specific embodiment, the fixing layer 6 is made of a medical-grade acrylic adhesive, which has strong viscosity but does not cause irritation to the skin. It is usually treated with hypoallergenic properties to further improve the safety factor of the nasal mask.

[0034] Specifically, a release liner is provided on one side of the fixing layer 6 away from the contact layer 3, and the release liner can be bonded to the fixing layer 6. When in use, the release liner is separated from the fixing layer 6 so that the fixing layer 6 is bonded to the patient's skin. The release liner can be a release paper or a release film to protect the sticky surface of the fixing layer 6, and is convenient to use, which is conducive to improving the convenience of operation.

[0035] In this specific embodiment, the cover body 1 is a triangular structure matching the connection layer 2 to support the connection layer 2 made of a flexible material.

[0036] In order to prevent the nasal mask from causing damage to the patient, the edge of the mask body 1 has a transition arc surface to protect the skin near the patient's nose and improve the safety factor of the nasal mask.

[0037] In order to facilitate the connection with the non-invasive assisted ventilation equipment, the mask body 1 has an access hole 8, which is connected to the oxygen supply chamber. The mask body 1 can be connected to the non-invasive assisted ventilation equipment using the access hole 8 to deliver oxygen to the oxygen supply chamber to ensure the smooth implementation of non-invasive assisted ventilation.

[0038] In practical applications, the number of access holes 8 is two, and the number of access holes 8 can be adjusted according to different models of non-invasive assisted ventilation equipment to improve the adaptability of the nasal mask.

[0039] More specifically, the mask body 1 has a thickened portion 9, and the access hole 8 is arranged in the thickened portion 9, so as to enhance the structural strength of the nasal mask and ensure smooth connection between the nasal mask and the non-invasive assisted ventilation device.

[0040] It should also be noted that the breathing port 7 is T-shaped, with the smaller opening end of the breathing port 7 located near the patient's nose wing, and the larger opening end located between the patient's upper lip and nose, to ensure smooth delivery of oxygen.

[0041] Embodiment 2

[0042] This embodiment provides a non-invasive assisted ventilation system, including a non-invasive assisted ventilation device and a nasal mask suitable for reducing nasal air leakage under non-invasive assisted ventilation in Embodiment 1. The non-invasive assisted ventilation device is connected to the access hole 8 of the nasal mask by an air delivery tube to achieve smooth oxygen delivery. The nasal mask is provided with a contact layer 3 made of artificial leather and a fixing layer 6 made of a viscous material to reduce the pressure injury of the nasal mask on the nose, and at the same time, the nasal mask fits more closely with the skin on both sides of the nose, reducing the occurrence of air leakage, so that the non-invasive assisted ventilation system maintains a stable airflow, thereby improving the clinical effect of non-invasive ventilation of newborns.

[0043] Terminology explanation:

[0044] Respiratory Distress Syndrome (RDS): Premature infants are prone to RDS because their lungs are not fully developed. NIV can provide continuous positive airway pressure (CPAP) or bi-level positive airway pressure (BiPAP) to help keep the alveoli open and improve oxygenation.

[0045] Transient dyspnea (TTN): Newborns may experience TTN after birth due to incomplete absorption of lung fluid. NIV can provide the necessary respiratory support to help newborns get through this stage smoothly.

[0046] Bronchopulmonary dysplasia (BPD): Long-term use of mechanical ventilation and high-concentration oxygen may lead to BPD. NIV, as a non-invasive method, can reduce the risks associated with mechanical ventilation and promote lung development.

[0047] Obstructive sleep apnea (OSA): For newborns with OSA, NIV can improve breathing quality by providing positive airway pressure, preventing airway collapse.

[0048] Advantages of non-invasive assisted ventilation: 1. Reduce invasive operations: NIV does not require intubation, reducing the risk of intubation-related complications such as infection, airway damage, and bronchopulmonary dysplasia. 2. Improve comfort: Using equipment such as nasal masks or nasal plugs can increase the comfort of newborns and reduce the pain and discomfort caused by intubation. 3. Protect lung tissue: The positive airway pressure provided by NIV can effectively prevent alveolar collapse, reduce lung damage, and is conducive to the protection and recovery of lung tissue. 4. Easy to care and manage: NIV equipment is easy to operate and manage, and nursing staff can more conveniently monitor and adjust ventilation parameters to improve nursing efficiency.

[0049] Clinical effects of non-invasive assisted ventilation: 1. Improve oxygenation: NIV can provide continuous positive airway pressure, improve oxygenation, increase blood oxygen saturation, and help newborns recover faster. 2. Reduce respiratory work: NIV can effectively reduce the respiratory work of newborns and reduce the respiratory burden by reducing respiratory resistance and increasing alveolar ventilation. 3. Reduce complications: The use of NIV can reduce complications caused by endotracheal intubation, such as pneumonia, pneumothorax, and bronchopulmonary dysplasia.

[0050] The application of non-invasive assisted ventilation in neonates provides a safe and effective means of respiratory support for premature infants and neonates with respiratory diseases. By reducing invasive procedures and complications, NIV helps improve the respiratory status and clinical outcomes of neonates and improves their quality of life.

[0051] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
