DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a mask for bronchoscopic examination, comprising a mask body 1, a mounting cavity 4 being provided on the mask body 1, and a support member 3 being provided in the mounting cavity 4; the support member 3 comprising an adaptable portion 32 and a sealing portion 34; wherein, when the bronchoscopic instrument passes through the support member 3, the adaptable portion 32 supports the bronchoscopic instrument while also adapting to changes in the use angle of the bronchoscopic instrument; the sealing portion 34 is conical, and the bronchoscopic instrument passing through the interior thereof is sealed in the mounting cavity 4 by the sealing portion 34.

[0021] In summary, after the bronchoscope passes through the support member 3, the adaptable portion 32 and the sealing portion 34 on the support member 3 can be used to support the bronchoscope and seal the bronchoscope on the mask body 1 at the same time. After the bronchoscope is inserted, the adaptable portion 32 and the sealing portion 34 can automatically fill the gap between the bronchoscope and the support member 3, so no other operations are required, thereby solving the problem that the existing variable diameter balloon needs to be inflated with an empty needle and then the channel is closed, which is cumbersome to operate.

[0022] Furthermore, the device can prevent the patient's blood oxygen saturation from decreasing during examination while ensuring a high concentration of oxygen in the mask body 1; in particular, the sealing portion 34 adopts a conical design and an opening on the cone to achieve airtightness while being adaptable to various types of bronchoscopes, and can also solve the problem of flap structures on the market that require different specifications of flap openings to be selected according to the thickness of the bronchoscope to achieve closure.

[0023] To solve the problem that the products on the market either have the oxygen supply channels on the same interface (dual oxygen supply interface), which cannot avoid the oxygen supply tube without an exhalation channel, or have no oxygen supply tube interface (only a breathing balloon interface), which cannot be used in a large number of department environments where only oxygen tubes are used for oxygen supply.

[0024] To this end, the mask body 1 is also provided with a first interface 2 and a second interface 5. Due to the provision of two interfaces, the device can be connected to different gas delivery devices, for example, it can be adapted to the oxygen supply environment in different clinical scenarios; wall-mounted central oxygen supply system, oxygen cylinder, ventilator, anesthesia machine, breathing bag.

[0025] Based on this, two interfaces are used to connect with different gas delivery devices to expand the applicability of the mask body 1.

[0026] Furthermore, since the mask body 1 is also provided with a plug 7 for sealing the first interface 2 and the second interface 5, the oxygen supply channels can be opened or closed by the plug 7 according to clinical work needs, thereby better facilitating clinical needs.

[0027] Based on this, the mask body 1 provides two oxygen supply interfaces. The first interface 2 can be connected to the oxygen supply tube, and oxygen is supplied through a wall-mounted oxygen supply short and an oxygen cylinder for patients without obvious respiratory disorders; in addition, the first interface 2 can also be used as an exhalation channel to avoid poor exhalation; the second interface 5 can be connected to a breathing bag and a ventilator for patients with respiratory disorders and patients with respiratory depression, and at this time, the first interface 2 needs to be sealed with a plug 7.

[0028] In addition, since the mounting cavity 4 is also provided with a clamping ring 8, and the clamping ring 8 is inserted into the inner wall surface of the mounting cavity 4, the support member 3 is fixed in the mounting cavity 4. Therefore, when the clamping ring 8 is inserted into the mounting cavity 4, the support member 3 can be fixed in the mounting cavity 4 by utilizing the interference fit between the clamping ring 8 and the outer wall surface of the mounting cavity 4; in addition, the adaptable portion 32 and the sealing portion 34 are both made of elastic rubber material; wherein, the adaptable portion 32 and the sealing portion 34 are preferably made of silicone material.

[0029] On the basis of the above scheme, since the support member 3 also includes a clamping ring 30 and a pressing ring 35; the clamping ring 30 is connected with the pressing ring 35 to assemble the adaptability portion 32 and the sealing portion 34 together, the disassembly and assembly of the support member 3 is simple and convenient.

[0030] Specifically, the clamping ring 30 passes through the adaptable portion 32 and the sealing portion 34 through the provided pin 31 and is adaptively connected with the slot 36 provided on the pressure ring 35 .

[0031] Based on this, the clamping ring 30, the adaptable part 32, the sealing part 34 and the pressure ring 35 are combined together by using the above method, which can simplify the combination method of the support member 3 while ensuring the structural stability of the support member 3 itself.

[0032] Furthermore, since a blocking cover 6 is provided on the outside of the installation cavity 4, and the blocking cover 6 is adaptively connected to the installation hole 33 provided on the support member 3 to seal the installation cavity 4, the blocking cover 6 can be used to seal the installation cavity 4 after the bronchoscope is taken out to avoid air leakage in the mask body 1.

[0033] Based on this, since most patients undergoing bronchoscopy have respiratory infectious diseases, if the patient has a respiratory infectious disease, the plug 7 and the plug cover 6 can be used to close the various channels on the mask body 1 to avoid infection of medical staff and pollution of the environment, thereby minimizing the problem of cross infection between doctors and patients in the hospital.

[0034] In the above-mentioned device, the operating channel of the mask body 1 is improved to achieve good airtightness and passability, and the operating steps can be simplified; at the same time, it can also prevent infectious patients from contaminating other personnel and the environment, especially when encountering respiratory depression, inspection and rescue can be carried out at the same time.

[0035] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
