Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a split non-invasive ventilator mask. Background Art

[0002] At present, non-invasive ventilator masks have been widely used in clinical medicine and have been widely applied in assisting patients to breathe. Non-invasive ventilator masks are usually used when patients have difficulty breathing and need to receive oxygen.

[0003] Although the current non-invasive ventilator masks can improve the convenience of patients receiving oxygen, in the actual use process, the inventor found that the current non-invasive ventilator masks still have deficiencies, specifically:

[0004] In addition to the conventional air inlet pipe provided on the current non-invasive ventilator mask, there are usually a channel for connecting the nasal cavity and a channel for connecting the oral cavity. The channels are used to connect the corresponding sputum suction tubes or drinking tubes. In the actual operation process, when it is necessary to suction sputum from the patient's nasal cavity, the sputum suction tube is usually matched with the channel on the mask for connecting the nasal cavity, and the sputum suction tube is inserted into the patient's nasal cavity. When the patient needs to drink water, the drinking tube is usually matched with the channel on the mask for connecting the oral cavity, and the drinking tube is inserted into the patient's oral cavity; and usually, the sputum suction operation on the patient and the drinking operation of the patient are not carried out synchronously, so that when the channel on the mask for connecting the nasal cavity cooperates with the sputum suction tube to work, the channel on the mask for connecting the oral cavity is idle, or when the channel on the mask for connecting the oral cavity cooperates with the drinking tube to work, the channel on the mask for connecting the nasal cavity is idle. Thus, it is not conducive to improving the utilization rate of the channels on the mask for connecting the nasal cavity or the oral cavity.

[0005] Therefore, based on the above deficiencies, there is an urgent need to design a split non-invasive ventilator mask at present to improve the utilization rate of the channels on the mask for connecting the nasal cavity or the oral cavity. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a split non-invasive ventilator mask to improve the utilization rate of the channels on the mask for connecting the nasal cavity or the oral cavity, aiming at the problem that one of the channels on the mask for connecting the nasal cavity and the channel for connecting the oral cavity is idle due to the fact that the sputum suction operation and the drinking operation on the patient are not carried out synchronously at present.

[0026] 1. In the solution of this application, by setting up a sputum suction and drinking water component, the sputum suction and drinking water component includes a first pipe and three pull strips, and a first hole and three second holes are provided on the mask body. The first pipe is matched with the first hole, and the pull strips are matched with the second holes. By controlling the movement of the three pull strips, the position of the end of the first pipe away from the mask body relative to the mask body can be adjusted. In this way, when the patient needs sputum suction, by pulling the pull strips, the end of the first pipe away from the mask body can be aligned with the patient's nasal cavity, and then the sputum suction tube is inserted into the first pipe, and the sputum suction tube extends along the first pipe into the patient's nasal cavity to perform the sputum suction operation. When the patient needs to drink water, by pulling the pull strips, the end of the first pipe away from the mask body can be aligned with the patient's mouth, and then the drinking water tube is inserted into the first pipe, and the drinking water tube extends along the first pipe into the patient's mouth to perform the drinking water operation. Thus, the first pipe can be matched with the sputum suction tube or the drinking water tube. When performing the sputum suction operation, there is no situation where the channel for connecting the mouth on the mask body is idle. When performing the drinking water operation, there is no situation where the channel for connecting the nasal cavity on the mask body is idle. Therefore, the utilization rate of the channel for connecting the nasal cavity or the mouth on the mask body can be improved, and the setting of the first pipe can play a guiding role during the insertion of the sputum suction tube or the drinking water tube, and can improve the convenience of inserting the sputum suction tube or the drinking water tube into the human body;

Specifically, the first secondary limiting part is connected to the first pipe, and the first limiting part and the first secondary limiting part are respectively located on different sides of the mask body to limit the position of the first fixing buckle relative to the first hole, so as to improve the stability of the connection between the first pipe and the first hole;

[0028] 3. Further, by setting up a second fixing buckle, the second fixing buckle is sleeved on the pull strip, and the second fixing buckle is detachably connected to the second hole. When the pull strip moves relative to the second fixing buckle, there is a resistance effect between the pull strip and the second fixing buckle, so as to adjust the position of the pull strip relative to the second fixing buckle, and can also improve the stability of the position of the pull strip relative to the second fixing buckle; At the same time, in this application, the first fixing buckle is detachably connected to the first hole, and the second fixing buckle is detachably connected to the second hole, so as to facilitate the separation of the mask body and the sputum suction and drinking water component, thus facilitating the disinfection of the mask body and the replacement of the sputum suction and drinking water component, so as to facilitate the reuse of the mask body;

[0029] 4. Further, by providing a sleeve on the drawbar, with one end of the sleeve connected to the drawbar and the other end connected to the second fixing buckle, the part of the drawbar connected to the sleeve divides the drawbar into a first part of the drawbar and a second part of the drawbar, such that the first part of the drawbar is located outside the mask body, and the second part of the drawbar can extend into the inside of the mask body. When the patient wears the mask body, the second part of the drawbar can be isolated from the external environment. When the drawbar moves relative to the second hole, it can prevent the second part of the drawbar from being contaminated by the external environment. At the same time, the sleeve can restrict the movement range of the drawbar when it moves relative to the second hole, which can improve the stability of the cooperation between the drawbar and the second hole and prevent the drawbar from disengaging from the second hole.
