Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a non-invasive ventilator mask. Background Art
[0002] Non-invasive ventilator-assisted breathing is an important treatment for respiratory diseases such as COPD. It consists of two parts: the ventilator itself and the non-invasive ventilator mask. The non-invasive ventilator's parameters are set to provide the patient with a certain level of expiratory and inspiratory pressure. The non-invasive ventilator mask determines whether the parameters set by the doctor are fully applied during the patient's treatment.
[0003] There are several problems with the current clinical non-invasive ventilator masks. First, the softness of the material that fits the bottom of the non-invasive ventilator mask to the patient's face cannot be adjusted, and in order to reduce air leakage, it will fit very tightly, causing discomfort or even pressure injuries to the patient, bringing additional pain to the patient. Secondly, during the treatment process, a nasal catheter in the mask will be used for oxygen inhalation, and a nasogastric tube or nasointestinal tube will be used for enteral nutrition. The non-invasive ventilator masks commonly used in clinical practice do not have a reserved passage for the nasogastric tube, nasogastric tube or nasointestinal tube, and are directly pressed against the face. This will cause additional air leakage and affect the treatment effect. At the same time, it is very easy to cause device-related pressure damage, leading to clinical adverse events. Finally, when the patient needs to be suctioned with a suction tube or bronchoscopy, the entire mask needs to be removed for the operation, which can easily cause hypoxia or even life-threatening danger to the patient. Utility Model Content
[0004] The utility model provides a non-invasive ventilator mask to solve the problem that the existing mask has no reserved passage for a nasal catheter, a nasogastric tube or a nasointestinal tube, and the entire mask needs to be removed when suctioning the patient with a sputum suction tube or a bronchofiberscope.
[0005] In order to alleviate the above technical problems, the technical solution provided by the present invention is:
[0006] A non-invasive ventilator mask comprises a mask body, wherein an airbag is provided at a contact portion between the mask body and the patient's face, wherein a notch is provided on the airbag, the notch dividing the airbag into two arc-shaped segments. When the airbag is inflated, the two arc-shaped segments contact to close the notch.
[0007] The mask body is provided with a sputum suction hole.
[0008] Furthermore, the mask body is connected to an air tube, and the air tube is connected to the airbag.
[0009] Furthermore, a valve is provided at the end of the trachea.
[0010] Furthermore, a raised shell is provided on the mask body, and the sputum suction hole is opened in the raised shell.
[0011] Furthermore, small holes are provided on the raised shell around the sputum suction hole, and carbon dioxide exhaled by the patient is discharged through the small holes.
[0012] Furthermore, a blocking cover is connected to the raised shell, and the blocking cover is used to close the sputum suction hole.
[0013] Furthermore, the mask body is connected to an oxygen inlet tube, and the oxygen inlet tube is connected to a ventilator.
[0014] Furthermore, the end of the oxygen inlet tube is connected to a connecting tube, and the connecting tube is connected to a pipeline of the ventilator.
[0015] Furthermore, a fixing belt is installed on the mask body, a through hole is opened on the fixing belt, and the oxygen inlet tube passes through the through hole on the fixing belt.
[0016] Furthermore, both ends of the fixing belt are provided with buckles that cooperate with each other.
[0017] The beneficial effects of the present invention are analyzed as follows:
[0018] A non-invasive ventilator mask includes a mask body. An airbag is provided at the contact portion between the mask body and the patient's face. The airbag is provided with a notch that divides the airbag into two arc-shaped segments. After the airbag is inflated, the two arc-shaped segments contact to close the notch. A sputum suction hole is provided on the mask body.
[0019] The mask body is used to cover the patient's mouth and nose and provide breathing support for the patient. The airbag is set at the contact point between the mask body and the patient's face. Its function is to provide an adjustable, soft contact surface to increase the patient's comfort and reduce the risk of pressure injury. The softness of the airbag can be adjusted by the inflation amount to adapt to the facial contours and needs of different patients. A notch is opened on the airbag, dividing the airbag into two arc-shaped segments. When the airbag is inflated, the two arc-shaped segments will contact each other and close the notch to form a complete airbag that fits the patient's face. This design allows the airbag to better adapt to the patient's facial shape when inflated and provides Provide more uniform pressure distribution. In addition, the gap also allows nasal catheters, nasogastric tubes or nasointestinal tubes to pass through, avoiding the aforementioned tubes being directly pressed against the face by the breathing mask, resulting in a large amount of air leakage in the mask body. At the same time, it also avoids the occurrence of device-related pressure damage. After the airbag is inflated, the gap is closed, clamping the above-mentioned tubes to provide stable support force and avoid air leakage. The suction hole is opened on the mask body for inserting a suction tube for suction when needed. This design avoids the inconvenience and potential risks of removing the entire mask for suction, allowing patients to suction without interrupting respiratory support.

[0029] Example
[0030] like Figure 1-Figure 3 As shown, a non-invasive ventilator mask includes a mask body 100. The contact portion of the mask body 100 with the patient's face is provided with an airbag 200. The airbag 200 is provided with a notch 230. The notch 230 divides the airbag 200 into two arc segments. After the airbag 200 is inflated, the two arc segments contact to close the notch 230. A sputum suction hole 320 is provided on the mask body 100.
[0031] The working mechanism of the non-invasive ventilator mask provided in this embodiment is as follows:
[0032] The mask body 100 is used to cover the patient's mouth and nose and provide breathing support for the patient. The airbag 200 is set at the contact part between the mask body 100 and the patient's face. Its function is to provide an adjustable, soft contact surface to increase the patient's comfort and reduce the risk of pressure injury. The softness of the airbag 200 can be adjusted by the inflation amount to adapt to the facial contours and needs of different patients. The notch 230 is opened on the airbag 200, dividing the airbag 200 into two arc-shaped segments. When the airbag 200 is inflated, the two arc-shaped segments will contact each other and close the notch 230, thereby forming a complete airbag 200 that fits the patient's face. This design allows the airbag 200 to better adapt to the patient's face when inflated. The notch 230 also allows a nasal catheter, a nasogastric tube or a nasointestinal tube to pass through, thereby preventing the aforementioned tube from being directly pressed against the face by the breathing mask, causing a large amount of air leakage in the mask body 100. At the same time, it also avoids the occurrence of device-related pressure damage. After the airbag 200 is inflated, the notch 230 is closed, clamping the aforementioned tube to provide a stable support force while avoiding air leakage. The suction hole 320 is provided on the mask body 100 for inserting a suction tube for suctioning when needed. This design avoids the inconvenience and potential risks of removing the entire mask for suctioning, allowing patients to perform suctioning without interrupting respiratory support.
[0033] Among the optional methods of this embodiment, the more preferred ones are:
[0034] The mask body 100 is connected to an air tube 210 , and the air tube 210 is communicated with the air bag 200 .
[0035] The trachea 210 penetrates the mask body 100 and communicates with the airbag 200 . The mask body 100 provides support for the trachea 210 , and the airbag 200 can be inflated or deflated through the trachea 210 .
[0036] Among the optional methods of this embodiment, the more preferred ones are:
[0037] A valve 220 is provided at the end of the air pipe 210 .
[0038] The valve 220 is used to control the on / off flow of the airflow in the trachea 210, thereby achieving precise control over the inflation or deflation operation of the airbag 200. The valve 220 is set to manual operation, allowing medical staff to adjust the inflation volume of the airbag 200 at any time according to the patient's condition and needs to achieve the best sealing effect and comfort.
[0039] Among the optional methods of this embodiment, the more preferred ones are:
[0040] A protruding shell 300 is provided on the mask body 100 , and a sputum suction hole 320 is opened in the protruding shell 300 .
[0041] The raised shell 300 provides an enlarged internal space for the mask body 100, which ensures the storage capacity of oxygen on the one hand and can accommodate the carbon dioxide exhaled by the patient on the other hand. The suction hole 320 is opened in the raised shell 300, so that there is sufficient operating space when performing suction operations, while providing sufficient operating field of view for the operation.
[0042] How to reduce the re-inhalation of carbon dioxide:
[0043] Small holes 310 are provided on the raised shell 300 around the sputum suction hole 320 , and carbon dioxide exhaled by the patient is discharged through the small holes 310 .
[0044] When a patient exhales, the exhaled gas contains a large amount of carbon dioxide. By arranging these small holes 310 around the small holes 310, an effective exhaust channel can be provided, so that the exhaled carbon dioxide can be quickly and smoothly discharged from the outside of the mask instead of being retained inside the mask. If too much carbon dioxide accumulates inside the mask, the patient may inhale some of the exhaled gas when inhaling, which is the so-called "re-inhalation". This will not only reduce breathing efficiency, but may also affect the patient's blood oxygen saturation. The design of the small holes 310 can significantly reduce the carbon dioxide concentration inside the mask, thereby avoiding or reducing the occurrence of re-inhalation.
[0045] Among the optional methods of this embodiment, the more preferred ones are:
[0046] A blocking cover 330 is connected to the raised shell 300 , and the blocking cover 330 is used to close the sputum suction hole 320 .
[0047] When suction operation is not required, the plugging cover 330 can tightly seal the suction hole 320 to prevent gas leakage inside the mask, which helps to maintain the sealing of the mask and ensure that the oxygen provided by the ventilator can be fully and effectively delivered to the patient's respiratory tract, while reducing the accumulation and repeated inhalation of carbon dioxide. The sealing effect of the plugging cover 330 can also prevent foreign matter such as dust and bacteria from entering the interior of the mask through the suction hole 320, which helps to keep the mask clean and hygienic and reduce the risk of infection for patients.
[0048] Among the optional methods of this embodiment, the more preferred ones are:
[0049] The mask body 100 is connected to an oxygen inlet tube 120 , which is connected to a ventilator.
[0050] The main function of the oxygen inlet tube 120 is to transport the oxygen generated by the ventilator to the inside of the mask for the patient to breathe. Specifically, one end of the oxygen inlet tube 120 is connected to the mask body 100 to ensure that oxygen can smoothly enter the inside of the mask, and the other end is connected to the ventilator. In this way, the ventilator can generate oxygen of corresponding concentration and flow according to the set parameters and the patient's breathing needs, and transport it to the mask through the oxygen inlet tube 120.
[0051] Among the optional methods of this embodiment, the more preferred ones are:
[0052] The end of the oxygen inlet tube 120 is connected to a connecting tube 130 , which is connected to a pipeline of a ventilator.
[0053] The main function of the connecting tube 130 is to connect the oxygen inlet tube 120 with the pipeline of the ventilator to form a complete oxygen delivery system. In this way, the oxygen generated by the ventilator can pass through the pipeline, the connecting tube 130 and the oxygen inlet tube 120, and finally enter the interior of the mask body 100 for the patient to breathe. The mask body 100 is connected to the ventilator through the connecting tube 130, so that the mask body 100 is easy to disassemble and replace.
[0054] Regarding how to wear the mask body 100, specifically:
[0055] A fixing belt 110 is installed on the mask body 100 . A through hole is opened on the fixing belt 110 , and the oxygen inlet tube 120 passes through the through hole on the fixing belt 110 .
[0056] The fixing strap 110 not only helps to firmly fix the mask on the patient's face, but also ensures the smoothness of the oxygen inlet tube 120 during wearing. The fixing strap 110 is installed on the mask body 100, usually at the edge or specific position of the mask so that it can fit closely to the patient's head or face. The length and width of the fixing strap 110 can be adjusted according to the size and shape of the mask to ensure the best wearing effect and comfort. A through hole is opened on the fixing strap 110. The design of the through hole allows the oxygen inlet tube 120 to pass through the fixing strap 110 smoothly without being obstructed or squeezed. In this way, when the patient wears the mask, the oxygen inlet tube 120 can maintain its original position and shape, ensuring that oxygen can smoothly enter the interior of the mask.
[0057] Among the optional methods of this embodiment, the more preferred ones are:
[0058] Both ends of the fixing belt 110 are provided with buckles 111 that cooperate with each other.
[0059] The design of the buckle 111 allows the fixing belt 110 to be conveniently fixed on the patient's head or face. When the patient wears the mask, the fixing belt 110 can be passed around the head or ears, and then the buckles 111 at both ends of the fixing belt 110 can be fastened to each other to firmly fix the mask on the face.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
