Technical Field

The present invention relates to the field of medical equipment, and more specifically to an infection-proof mask for respiratory endoscopy diagnosis and treatment.

Background Art

As a basic diagnosis and treatment method for respiratory diseases, fiberoptic bronchoscopy is now more and more widely used in clinical practice. With the improvement of operating level and the development of medical equipment, some patients who originally needed surgical treatment can complete the treatment under fiberoptic bronchoscopy, with less damage and faster recovery. However, during fiberoptic bronchoscopy, the bronchoscope enters the airway through the nose or mouth. Due to the stimulation of the tracheal mucosa, the patient will have severe coughing and expectoration. Pathogenic microorganisms can easily contaminate the treatment room and cross-infect medical staff and other patients. Especially for patients with respiratory infectious diseases, a large number of droplets are produced when coughing.

A sealing ring 14 for sealing with the endoscope is provided in the annular groove 13. A second mounting seat 15 is provided on the sealing sleeve 11. The second mounting seat 15 is provided with a tongue depressor assembly 16 for assisting the endoscope to be inserted into the oral cavity. The sealing sleeve 11 is provided with a third mounting seat 17 for installing a sputum suction device 18. When in use, the doctor pushes the endoscope into the nasal cavity or oral cavity through the first mounting seat 12. When passing through the oral cavity, if the tongue depressor assembly 16 is needed, the tongue depressor assembly 16 is controlled to suppress the tongue root. In addition, during endoscopic observation, sputum will be produced due to the stimulation of the tongue depressor 34 and the endoscope to the oral mucosa, throat and trachea 45. The sputum in the oral cavity is sucked out by the sputum suction device 18 to increase the patient's comfort.

The mask is designed to form a closed space and isolate the patient's mouth and nose when worn on the patient's face. When in use, the mask is connected to a collection bottle 5 provided with a negative pressure device 7 to collect the gas exhaled by the patient. The filter device filters and collects the exhaled gas, and the oxygen cylinder 4 is connected to the mask to supply oxygen to the patient. An operating area is provided on the mask, and the operating area is provided with a first mounting seat 12 for the endoscope to extend into, a second mounting seat 15 for mounting a tongue depressor 34, and a third mounting seat 17 for mounting a sputum suction device 18, so that the doctor can perform endoscopic examination in isolation from the mask. During operation, the doctor or an assistant nurse can directly operate the tongue depressor 34, the endoscope and the sputum suction device 18 outside the mask, so as to solve the problem of needing to take off the mask during endoscopic operation in the past, and avoid contamination by droplets generated by the patient's cough during the endoscopic operation.

As an improved specific implementation, the third mounting seat 17 is detachably connected to the sputum suction device 18, and the third mounting seat 17 is an adjustable valve body. The third mounting seat 17 includes a shell 19, a valve core 20, a mounting plate 21, and a first spring member 22. A "convex"-shaped through hole 23 is provided in the center of the shell 19, and the aperture of the through hole 23 is reduced toward the outer side of the mask body 1. A first boss 24 is provided inside the shell 19 at the aperture reduction location, and the valve core 20 and the first boss 24 conflict with each other. The valve core 20 is a "convex" shape that matches the through hole 23. One end of the first spring member 22 is connected to the mounting plate 21, and the other end of the first spring member 22 is connected to the valve core 2 0, the first spring member 22 keeps the valve core 20 in contact with the first boss 24, the mounting plate 21 includes a mounting ring 25 and a slider 26, a slide groove 27 is provided on the shell 19, the slider 26 is slidably connected with the slide groove 27, the slider 26 extends out of the outer wall of the shell 19 through the slide groove 27, a second boss 28 is provided on the outer wall of the shell 19, a second spring member 29 is in contact with the slider 26 and the second boss 28, a rubber sleeve 30 for accommodating and enclosing the second spring member 29 and the slider 26 is provided on the outer wall of the shell 19, the rubber sleeve 30 is sealed and adhered to the shell 19, and the sputum suction device 18 is provided with a fixing member 31 for being fixedly installed on the third mounting seat 17.

By setting the sputum suction device 18 as a detachable structure, since the overall volume of the sputum suction device 18 is relatively large, it can be disassembled when not needed, which is convenient for endoscopic operation and avoids the mask being pulled downward due to its excessive weight without the support of a doctor. By providing an adjustable valve core 20 on the third mounting seat 17, the valve core 20 maintains mutual contact with the first boss 24 under the restoring force of the second spring member 29 and the first spring member 22, preventing the air inside the mask from flowing out through the third mounting seat 17. When in use, the tube wall of the sputum suction device 18 is installed on the third mounting seat 17 to push the slider 26 away from the first boss 24, while driving the valve core 20 and the first boss 24 to move. A gap is formed, and sputum can be sucked out through the through hole 23 of the shell 19 when the sputum suction device 18 is negatively pressured and filtered. When the sputum suction device 18 is installed on the outer wall of the third mounting seat 17, it is fixed by the fixing member 31, and the fixing member 31 can be a fastening ring, or it can be achieved by setting an internal thread on the inner side of the tube wall of the sputum suction device 18 and setting an external thread on the outer wall of the third mounting seat 17, and the sputum suction device 18 and the third mounting seat 17 are threadedly connected. The detachable structure disclosed above ensures that when the sputum suction device 18 is installed on the third mounting seat 17, the through hole 23 of the third mounting seat 17 remains unobstructed, and when the sputum suction device 18 and the third mounting seat 17 are disassembled, the through hole 23 of the third mounting seat 17 is sealed and closed.

As an improved specific implementation, a first O-ring 32 for contacting the inner wall of the shell 19 is embedded on the contact surface between the valve core 20 and the inner wall of the shell 19. The valve core 20 and the inner wall of the shell 19 are in close contact through the first O-ring 32, so that the through hole 23 remains closed.

As an improved specific embodiment, the outer wall of the shell 19 facing the outer side of the mask body 1 is provided with a second O-ring 33 for interference fit with the sputum suction pump 18, which plays a sealing role when the sputum suction pump 18 is installed and connected to the shell 19, and keeps the third mounting seat 17 in a negative pressure state when the sputum suction pump 18 is working.

As an improved specific embodiment, the tongue depressor assembly 16 includes a tongue depressor 34 and an operating rod 35. The tongue depressor 34 is fixedly mounted on the second mounting seat 15 on the inner side of the mask body 1. The second mounting seat 15 is provided with a blind hole 36 on the outer side of the mask body 1, and the operating rod 35 is plugged into the blind hole 36.

The tongue depressor assembly 16 is configured as a split structure. When in use, the operating rod 35 is grasped to control the direction of the second mounting seat 15 and then the tongue depressor 34, so that the structure is simple and convenient for disassembly and disinfection.

As an improved specific implementation, the operation area includes an endoscope operation area 37, a tongue depressor operation area 38 and a sputum suction device operation area 39.

By dividing the operation area into zones, the endoscope, tongue depressor 34 and sputum suction device 18 will not affect each other when being controlled. The sealing sleeve 11 is relatively independent, which makes it more flexible to control the directions of the first mounting seat 12, the second mounting seat 15 and the third mounting seat 17. In addition, by setting a retractable bellows 40, the sealing sleeve 11 has a certain stretching space in all directions and can be stored when not in use, so that its overall volume is smaller, making the mask more comfortable to wear.

As an improved specific embodiment, the air outlet 3 is arranged at the lower end of the mask body 1, the collecting bottle 5 includes an upper layer and a lower layer, the upper layer of the collecting bottle 5 is provided with an air inlet 41 connected to the air outlet 3 and an air outlet 42 connected to the negative pressure device 7, the filter layer 6 is arranged in the lower layer of the collecting bottle 5, the filter layer 6 includes an activated carbon filter layer 43 and a filter cotton layer 44 adsorbed with disinfectant arranged in sequence, and the air inlet 41 of the collecting bottle 5 is provided with an air pipe 45 extending into the filter cotton layer 44.

By arranging an activated carbon filter layer 43 and a filter cotton layer 44 adsorbed with disinfectant in the collection bottle 5, the gas exhaled by the patient is sucked by the negative pressure device 7, and the gas is first introduced into the filter cotton through the trachea 45 to perform preliminary disinfection on the bacteria and viruses carried in the gas, and then the harmful substances are further filtered through the activated carbon layer.

The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
