Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a non-invasive ventilator mask for preventing pressure injuries. Background Art

[0002] Non-invasive ventilators are mainly suitable for a series of diseases such as severe asthma and emphysema that cause respiratory depression or respiratory failure. Compared with traditional endotracheal intubation or tracheotomy to increase alveolar ventilation, non-invasive ventilator ventilation has the advantages of being non-invasive and convenient. The ventilator mask is a very important auxiliary device in the use of the ventilator. The ventilator mask can effectively ensure the ventilation volume, discharge carbon dioxide and improve hypoxia, and plays an important role in the non-invasive ventilator treatment of patients.

[0003] At present, the sealing rings on the ventilator masks are mostly flexible cushions or single-layer air bags. The ventilator masks with flexible cushions, such as the sealing silicone pad disclosed in CN202222887442.5 and the protective pad disclosed in CN201820254934.1, compress the patient's facial skin for a long time. Wearing the mask for too long will cause ischemia of the patient's skin and subcutaneous tissue to form pressure sores, which may cause secondary trauma to the patient, causing some patients to refuse to use the ventilator and affect treatment. The ventilator masks with single-layer air bags, such as the ventilator mask for preventing pressure injuries disclosed in CN202220937158.1, improve comfort and enhance air tightness by setting air bags, but the air bags compress the same contact part of the nose and face skin for a long time, and there is a situation where the nose and face skin is red, swollen and painful due to continuous pressure. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art, and the purpose of the utility model is to provide a non-invasive ventilator mask that can prevent pressure injuries.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a non-invasive ventilator mask for preventing pressure injuries, comprising a mask body, the mask body having a ventilation tube interface that can be connected to a ventilator pipeline, and the end face of the mask body that contacts the skin is provided with a sealing structure; the sealing structure comprises a first inflatable airbag that can work independently and a second inflatable airbag arranged outside the first inflatable airbag, the ventilation tube interface is located in the area enclosed by the first inflatable airbag, the first inflatable airbag and the second inflatable airbag are respectively connected to the inflation and deflation device through a first conduit and a second conduit, and an air vent communicating with the interior of the mask body is provided in an area between the first inflatable airbag and the second inflatable airbag.

[0006] The above technical solution, by providing a first inflatable airbag and a second inflatable airbag, the first inflatable airbag and the second inflatable airbag work alternately to seal, so that different areas of the face are alternately pressurized, thereby greatly reducing the pressure damage to the patient's face, especially reducing the pressure on the bridge of the patient's nose, improving the patient's comfort and treatment effect; or the first inflatable airbag and the second inflatable airbag work simultaneously to seal, increasing the contact area with the skin, reducing pressure, and reducing pressure damage to the patient's face. By providing air holes, dry air can enter the mask body when the second inflatable airbag is sealed, inhibiting the proliferation of bacteria in the mask body.

[0007] In a preferred embodiment of the present invention, the interface connecting the first inflatable airbag and the first catheter is located inside the mask body, the mask body is provided with a first tracheal through hole for the first catheter to pass through, and the interface connecting the second inflatable airbag and the second catheter is located outside the mask body.

[0008] In the above technical solution, the first conduit passes through the first tracheal through hole and out of the mask body, which can avoid the first conduit being directly connected to the interface on the first inflatable airbag and affecting the seal between the mask body and the face.

[0009] In a preferred embodiment of the present invention, a plurality of massage heads are arranged at circumferential intervals in the second inflatable airbag.

[0010] The above technical solution, by setting a massage head, when the first inflatable airbag is used for sealing, the massage head in the second inflatable airbag works to massage the face to relax the face and avoid skin redness, swelling and pain caused by facial pressure.

[0011] In a preferred embodiment of the present invention, the massage head performs massage in a vibration or rotation manner.

[0012] In a preferred embodiment of the present invention, an oropharyngeal tube interface communicating with the interior of the mask body is provided at a position corresponding to the mouth of the mask body, and a sealing cover is connected to the oropharyngeal tube interface.

[0013] The above technical solution, by providing an oropharyngeal tube interface, can simultaneously perform sputum suction through the oropharyngeal tube interface when using a ventilator, thereby greatly improving the daily work efficiency of medical staff and increasing the treatment effect of patients.

[0014] In another preferred embodiment of the present invention, the oropharyngeal tube interface is located in an area inside or outside the first inflatable airbag; when the oropharyngeal tube interface is located in an area outside the first inflatable airbag, the first inflatable airbag ring is arranged outside the nose.

[0015] In the above technical solution, when the oropharyngeal tube interface is located in an area outside the first inflatable airbag, when suction is performed through the oropharyngeal tube interface, the patient's nasal area is sealed by the first inflatable airbag, so that the oxygen saturation value remains within a normal range.

[0016] In another preferred embodiment of the utility model, when the oropharyngeal tube interface is located in an area outside the first inflatable airbag, the sealing structure also includes a third inflatable airbag connected to the inflation and deflation device through a third catheter, the third inflatable airbag ring is arranged outside the mouth, and the oropharyngeal tube interface is located in the area enclosed by the third inflatable airbag.

[0017] In the above technical solution, when suctioning sputum, a third inflatable airbag is provided on the outer ring of the mouth to enhance the sealing effect and prevent the airflow generated during suctioning from entering the patient's nasal cavity through the gap between the first inflatable airbag and the facial skin, thereby effectively reducing the probability of infection caused by retrograde airflow in the nasal cavity.

[0018] In another preferred embodiment of the present invention, an interface for connecting the third inflatable airbag and the third catheter is located inside the mask body, and a third tracheal through hole for the third catheter to pass through is provided on the mask body.

[0019] In the above technical solution, the third conduit passes through the third tracheal through hole and out of the mask body, which can avoid the third conduit being directly connected to the interface on the third inflatable airbag and affecting the seal between the mask body and the face.

For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0029] The utility model provides a non-invasive ventilator mask for preventing pressure damage, such as Figure 1 As shown, in a preferred embodiment, the mask includes a mask body 1, the mask body 1 has a ventilation tube interface 2 that can be connected to the ventilator pipeline, and the end surface of the mask body 1 that contacts the skin is provided with a sealing structure. The sealing structure includes an annular first inflatable airbag 3 that can work independently and an annular second inflatable airbag 4 that is arranged outside the first inflatable airbag 3. The ventilation tube interface 2 is located in the area enclosed by the first inflatable airbag 3, and the area on the mask body 1 between the first inflatable airbag 3 and the second inflatable airbag 4 is provided with a vent hole 10 that communicates with the interior thereof.

[0030] The first inflatable airbag 3 and the second inflatable airbag 4 are connected to the inflation and deflation device 7 through the first conduit 5 and the second conduit 6 respectively. The inflation and deflation device 7 adopts an electric air pump that can be inflated and deflated in the prior art. The first conduit 5 and the second conduit 6 are respectively provided with a first valve 8 and a second valve 9 for controlling the on and off thereof, so that the first inflatable airbag 3 and the second inflatable airbag 4 can work respectively. In this embodiment, the interface connecting the first inflatable airbag 3 and the first conduit 5 is located inside the mask body 1, and the mask body 1 is provided with a first tracheal through hole 11 for the first conduit 5 to pass through, and the interface connecting the second inflatable airbag 4 and the second conduit 6 is located outside the mask body 1.

[0031] When in use, the mask body 1 is worn on the patient's face. The specific method of wearing and fixing the mask body 1 is prior art and will not be described in detail here.

[0032] In one embodiment, the first inflatable airbag 3 and the second inflatable airbag 4 work alternately to seal. Specifically, the first valve 8 is opened first, and the inflation and deflation device 7 is started to inflate the first inflatable airbag 3, so that the patient's face contacts the first inflatable airbag 3 to seal (preferably, the mask body 1 does not directly contact the patient's face), and then the first valve 8 and the inflation and deflation device 7 are closed; after a period of time (such as 5 minutes, 10 minutes, half an hour or one hour later), the second valve 9 is opened, and the inflation and deflation device 7 is started to inflate the second inflatable airbag 4, so that the patient's face contacts the second inflatable airbag 4, and then the inflation and deflation device 7 deflates the first inflatable airbag 3, and the second inflatable airbag 4 seals; after a period of time, the first inflatable airbag 3 is replaced to inflate to seal. The first inflatable airbag 3 and the second inflatable airbag 4 are alternately inflated and deflated through the inflation and deflation device 7, so that different areas of the face are alternately pressurized, thereby greatly reducing the patient's facial pressure injuries and improving the patient's comfort and treatment effect; and when the second inflatable airbag 4 is sealed, a small amount of dry air can enter the mask body 1 through the air vent 10 to inhibit the proliferation of bacteria in the mask body 1.

[0033] Among them, the alternating operation of the first inflatable airbag 3 and the second inflatable airbag 4 can be switched manually or automatically operated at a set time. The start and stop controlled by time is a prior art and will not be described in detail here.

[0034] In another embodiment, in normal state, the first inflatable airbag 3 and the second inflatable airbag 4 are both inflated to seal at the same time, thereby increasing the contact area with the skin to reduce pressure and reduce pressure injuries on the patient's face; after a period of time (e.g., 2 hours to 4 hours), the first inflatable airbag 3 is deflated and sealed by the second inflatable airbag 4; after a period of time (e.g., 15 minutes to 30 minutes), the first inflatable airbag 3 is inflated again, and the second inflatable airbag 4 is deflated and sealed by the first inflatable airbag 3, alternating once; after a period of time (e.g., 15 minutes to 30 minutes), the first inflatable airbag 3 and the second inflatable airbag 4 are both inflated to seal at the same time, and this cycle is repeated.

[0035] In the utility model, the shape of the mask body 1 is adapted to the patient's mouth and nose, and the shapes of the first inflatable airbag 3 and the second inflatable airbag 4 are also adapted to the mouth and nose. The end face of the mask body 1 in contact with the skin is a curved surface rather than a flat surface. The top of the mask body 1 has a groove corresponding to the bridge of the nose to reduce the pressure damage of the mask body 1 to the bridge of the nose.

[0036] In another preferred embodiment, a plurality of massage heads are arranged at intervals in the circumferential direction in the second inflatable airbag 4, and the massage heads are massaged by vibration or rotation, which is a prior art and will not be described in detail here. When the first inflatable airbag 3 is used for sealing, the massage heads in the second inflatable airbag 4 work to massage the face to relax the face.

[0037] In another preferred embodiment, an oropharyngeal tube interface 12 communicating with the inside of the mask body 1 is provided at a position corresponding to the patient's mouth, and a cover is connected to the oropharyngeal tube interface 12. In normal state, the oropharyngeal tube interface 12 is closed by the cover, and when the patient needs to suction sputum, the cover is opened and the sputum suction operation is performed through the oropharyngeal tube interface 12.

[0038] like Figure 1 and Figure 2 As shown, in the present invention, the oropharyngeal tube interface 12 is located in the area inside the first inflatable airbag 3, or in the area outside the first inflatable airbag 3. Figure 2 As shown, when the oropharyngeal tube interface 12 is located in the area outside the first inflatable airbag 3, the first inflatable airbag 3 is arranged outside the patient's nose. When suction is performed through the oropharyngeal tube interface 12, at least the first inflatable airbag 3 is inflated to seal the patient's nose area through the first inflatable airbag 3 to reduce air leakage and keep the oxygen saturation value within a normal range.

[0039] like Figure 3As shown, in another preferred embodiment, when the oropharyngeal tube interface 12 is located in an area outside the first inflatable airbag 3, the sealing structure also includes a third inflatable airbag 13 connected to the inflation and deflation device 7 through a third catheter 14, the third inflatable airbag 13 is arranged outside the patient's mouth, and the oropharyngeal tube interface 12 is located in the area enclosed by the third inflatable airbag 13; the interface connecting the third inflatable airbag 13 and the third catheter 14 is located inside the mask body 1, and the mask body 1 is provided with a third tracheal through hole 16 for the third catheter 14 to pass through.

[0040] When suctioning is not performed, the mask body 1 and the facial skin are sealed by the first inflatable airbag 3 and the second inflatable airbag 4, or alternately sealed by the two. When suctioning is performed, at least the first inflatable airbag 3 and the third inflatable airbag 13 are inflated and sealed. When suctioning, the third inflatable airbag 13 is provided on the outer ring of the mouth to enhance the sealing effect and prevent the airflow generated during suction from entering the patient's nasal cavity through the gap between the first inflatable airbag 3 and the facial skin, which can effectively reduce the probability of infection caused by retrograde airflow in the nasal cavity.
