Description

Technical Field

[0001] The present invention relates to the technical field of chest and lung imaging examination, and in particular to a breathing mask specially used for chest and lung imaging examination and a method of using the breathing mask. Background Art

[0002] Soon after Roentgen discovered X-rays in 1895, they were used in medicine to examine the human body and diagnose diseases, forming a new discipline of diagnostic radiology and laying the foundation for medical imaging. Diagnostic radiology is still the main content of medical imaging and is widely used. Currently, X-rays, CT scans, magnetic resonance imaging, and radioactive material imaging are commonly used.

[0003] A large part of imaging examinations in medical institutions is for chest and lung examinations. Due to the large size of the lungs, in order to observe alveolar lesions in certain parts of the lungs or other organs in the chest cavity, the patient's chest cavity needs to be expanded as much as possible so that it can be displayed more clearly per unit area.

[0004] Since imaging examinations also take a certain amount of time to shoot, the patient is required to take a deep breath, inhale as much air as possible and hold his breath for a while so that the inspector can take the picture.

[0005] However, in actual operation, some patients may have shortness of breath due to nervousness and fear during the test. Some elderly people, children, or patients with coughs or lung damage are not easy to hold their breath for a period of time after taking a deep breath, which is not convenient for medical imaging examination. Even the amount of air that patients can inhale through spontaneous breathing cannot expand the lungs and chest cavity to the state for medical imaging examination. Therefore, it is necessary to provide a breathing mask to assist patients.

[0006] Although some breathing masks on the market currently have the function of assisting breathing, they are not specifically used for lung and chest imaging examinations, especially lung and chest imaging examinations require holding the breath for a period of time after inhaling before exhaling. Existing breathing masks cannot solve the above problems and therefore cannot cooperate well with lung and chest imaging examinations. Therefore, the first applicant and the second applicant of this application jointly developed the breathing mask of this application. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a breathing mask specially used for chest and lung imaging examination and a method of using the breathing mask, which detects the patient's breathing condition and reminds the patient to hold his breath as required so that the patient's lungs and chest cavity can expand. The breathing mask is connected to a control console and the operation of the control console is coordinated to facilitate the imaging examination of the lungs and chest cavity, thereby ensuring the clarity of the lung and chest images and improving the accuracy of the examination.

[0008] The technical solution adopted by the present invention is: A breathing mask specially used for chest and lung imaging examination comprises a mask body with ear hanging ropes fixed on both sides, a base block is fixedly provided at the middle of the outer end surface of the mask body, an air pump A and an air pump B are fixedly provided at the upper and lower parts of the base block respectively, a nose pad and an air outlet pipe are fixedly provided at the inner end surface of the mask body corresponding to the positions of the air pump A and the air pump B respectively, a pair of air inlet pipes are provided at the top of the nose pad, an air inlet end A of the air pump A is connected to the atmosphere at the outer end of the mask body, an air outlet end A of the air pump A passes through the mask body and then is connected to the air inlet pipe respectively through the trachea A in the nose pad, and an air inlet end B of the air pump B passes through the mask body and then is connected to the air outlet pipe. The air outlet end B of the air pump B is connected to the atmosphere at the outer end of the cover, and also includes a pipe sleeve matched with the air inlet pipe and a contact piece matched with the air outlet pipe. A nasal plug is provided at the top of the pipe sleeve, and the nasal plug is provided with an air hole connected to the pipe sleeve. A battery, a processor and a communication device for communicating with the control console are provided in the base block. An airflow sensor A and a one-way valve A are provided in the air pipe A, and an airflow sensor B and a one-way valve B are provided in the air outlet pipe. The battery, air pump A, air pump B, airflow sensor A, airflow sensor B, one-way valve A, one-way valve B and the communication device are all electrically connected to the processor respectively.

[0009] A further improvement of the present invention is that the contact piece includes a flexible nose pad and a rigid limit baffle connected to each other, the nose pad matches the top of the nose pad, the tube sleeve is arranged on the top of the nose pad, the inner hole of the tube sleeve passes downward through the nose pad, and the mouth inlet tube is passed through and fixed to the limit baffle.

[0010] A further improvement of the present invention is that the nose pad is also provided with an air inlet hole, and the air inlet hole is connected with the air outlet A of the air pump A through an air pipe B provided in the nose pad, and a valve is provided in the air pipe B.

[0011] A further improvement of the present invention is that a sealing strip is provided at the edge of the cover body, the sealing strip is away from the end surface of the cover body, and an annular sealing sheet A is also provided along the sealing strip corresponding to the edge inside the cover body.

[0012] A further improvement of the present invention is that an annular sealing sheet B is provided at the bottom edge of the nasal plug.

[0013] A further improvement of the present invention is that an annular sealing sheet C is provided on the edge of the customized baffle.

[0014] A further improvement of the present invention is that an inserting port is provided at one end of the air outlet pipe located at the cover body, and the inlet pipe is plugged and sealed and fixedly connected with the air outlet pipe through the inserting port.

[0015] A further improvement of the present invention is that a nose bridge pad is also provided in the cover body at the upper part of the nose pad.

[0016] A further improvement of the present invention is that both ends of the ear hanging rope are respectively fixed to the outer end of the cover body through connectors, and a speaker is also fixed to the middle part of the ear hanging rope, and the speaker is electrically connected to the processor.

[0017] The method for using the breathing mask described above comprises the following steps: 1) First, fix the contact piece to the mask body, so that the nose pad is in contact with the top of the nose pad, and the tube sleeve is fixed on the corresponding air inlet pipe, and the inlet pipe is fixed to the outlet pipe through the plug interface; 2) Then, the mask is fixed to the face of the patient to be examined through the ear-hanging rope, and the nasal plugs are plugged into the patient's nostrils. At the same time, the mouth inlet tube is put into the patient's mouth, and the patient's mouth is closed and pressed against the limit baffle. Under the action of the ear-hanging rope, the speaker is just limited to the back of the ear-hanging rope and the patient's auricle; 3) After the processor receives the start signal from the console through the communication device, the processor controls the one-way valve A and the one-way valve B to open and close, and the processor controls the speaker to play the voice content A, so that the patient inhales through the nose and exhales through the mouth, so that the airflow sensor A and the airflow sensor B respectively collect the airflow information of the patient's breathing and transmit it to the processor; 4) The processor controls the speaker to play voice content B to enable the patient to continue taking deep breaths. When the patient fails to complete deep breaths for many times, the processor controls the air pump A and the one-way valve B to actively intervene and help the patient take deep breaths. When the airflow sensor A collects the patient's inspiratory flow information, the processor simultaneously controls the air pump A to start and the one-way valve B to close. The air pump A actively pumps external air into the patient's nasal cavity so that the patient's air intake can meet the air intake required for the patient's test. When the airflow collected by the airflow sensor A is greater than or equal to the air intake required for the patient's test, the processor simultaneously controls the air pump A to close and the one-way valve B to open; 5) When the airflow volume of the patient's inhalation in the airflow information collected by the airflow sensor A for m consecutive times can stably be greater than or equal to the amount of air inhaled by the patient during the test, but the time interval between the end of the airflow volume collected by the airflow sensor A (27) and the airflow information of the patient's exhalation collected by the adjacent airflow sensor B is less than the time required for the test, the processor controls the speaker to play the voice content C, so that the patient holds his breath after inhaling through his nose, until the processor controls the speaker to play the exhalation prompt tone, and the time interval between the speaker playing the exhalation prompt tone and the end of the airflow volume collected by the airflow sensor A is greater than or equal to the time required for the test; When the airflow sensor B collects the patient's exhaled airflow information before the processor controls the speaker to play the exhalation prompt tone, the processor controls the speaker to play the voice content C again before the airflow sensor A finishes collecting the patient's inhaled airflow next time, and controls the one-way valve B to close, until the processor controls the speaker to play the exhalation prompt tone, and the processor controls the one-way valve B to open again; 6) When the patient completes deep breathing for multiple times in succession and the breath-holding time between deep breathing meets the inspection requirements, the processor sends a signal to the console through the communication device that the inspection can be carried out, and after the processor receives the inspection signal sent by the console through the communication device, when the airflow sensor A collects the airflow of the patient's inhalation, the processor sends an inspection start signal to the console through the communication device to enable the console to carry out the inspection; 7) When the processor receives a signal from the console indicating that the examination is completed through the communication device, the processor controls the speaker to play voice content D to let the patient know that the examination is over, and then removes the mask, separates the contact from the mask, and places the contact in the processing box so that the mask can be used by the next patient.

[0018] A further improvement of the present invention is that in step 4), when the airflow sensor A has not stably collected the patient's inhaled airflow volume in the airflow information for m consecutive times during the most recent 2m consecutive times, the processor determines that the patient has been unable to complete deep breathing for many times; in step 5), when the airflow sensor A has stably collected the patient's inhaled airflow volume in the airflow information for m consecutive times, the processor determines that the patient has completed deep breathing for many times; when the airflow volume collected by the airflow sensor A each time ends until the adjacent airflow sensor A stops breathing, the processor determines that the patient has completed deep breathing for many times. When the time interval between the airflow information of the patient's exhalation collected by the airflow sensor B is less than the time required for the examination, the processor determines that the breath-holding time between deep breaths does not meet the examination requirements; in the step 6), when the airflow volume of the patient's inhalation in the airflow information collected by the airflow sensor A for m consecutive times can be stably greater than or equal to the air inhalation volume required for the patient's detection, the processor determines that the patient has completed deep breaths for multiple consecutive times; when the time interval between the end of the airflow volume collected by the airflow sensor A each time and the airflow information of the patient's exhalation collected by the adjacent airflow sensor B is greater than or equal to the time required for the examination, the processor determines that the breath-holding time between deep breaths meets the examination requirements.

[0019] A further improvement of the present invention is that the m is in the range of 2 to 5.

[0020] A further improvement of the present invention is that in the step 4), the console sends a signal of forced deep breathing exercise to the processor through the communication device. After the processor receives the signal of forced deep breathing exercise, when the airflow sensor A collects the patient's inspiratory flow information, the processor simultaneously controls the air pump A to start and the one-way valve B to close, and the air pump A actively pumps the outside air into the patient's nasal cavity, so that the airflow collected by the airflow sensor A this time is greater than the airflow collected last time; when the airflow collected by the airflow sensor A is greater than the airflow collected last time, the processor simultaneously controls the air pump A to close and the one-way valve B to open; when the airflow sensor B collects When the processor receives the patient's expiratory flow information, the processor controls the air pump B to start, and the air pump B assists the patient to exhale the air in the lungs through the mouth as quickly as possible, and the air flow sensor B collects the patient's exhaled air volume; when the air flow sensor A collects the patient's inspiratory flow information again, the processor controls the air pump B to shut down, and controls the start of the air pump A and the closing of the one-way valve B at the same time again, and repeats this step until the air flow collected by the air flow sensor A is greater than or equal to the air inhalation volume required for the patient's detection, so that the amount of air pumped in by the air pump A each time thereafter can ensure that the air flow collected by the air flow sensor A can maintain a value greater than or equal to the air inhalation volume required for the patient's detection.

[0021] A further improvement of the present invention is that in the step 5), when the airflow volume collected by the airflow sensor A and the airflow volume collected by the airflow sensor B can both maintain a volume greater than or equal to the air intake volume required for the patient's test, but the breath-holding time between multiple deep breaths does not meet the inspection requirements, the processor controls the one-way valve A and the one-way valve B to close and opens the air pump A and the valve after the airflow sensor A finishes collecting the airflow volume, and the air pump A pumps the air outside the mask into the mask through the air inlet, and then forms a relatively high-pressure sealed cavity between the mask and the patient's face through the action of an annular sealing sheet A provided along the sealing strip, an annular sealing sheet B provided at the bottom edge of the nasal plug, and an annular sealing sheet C provided at the edge of the customized baffle, and the relatively high pressure in the high-pressure sealed cavity makes the annular sealing sheet B and the annular sealing sheet C closely fit the edges of the nostrils and the mouth of the patient's face, respectively, to prevent the air inhaled by the patient from escaping from the nostrils or the mouth, and at this time, the patient's lungs and chest cavity are kept in the most expanded state, so as to facilitate the clearest image of the chest and lung examination.

[0022] A further improvement of the present invention is that after the processor receives the signal of completing the imaging sent by the console through the communication device, the processor controls the air pump A to close, and opens the air pump B and the one-way valve B at the same time. At this time, the air in the patient's lungs can be quickly exhaled with the assistance of the air pump B, and the air in the high-pressure sealed cavity between the mask body and the patient's face is discharged to the outside from the air inlet end A of the air pump A through the trachea B connected to the air inlet hole; when the air flow information of the patient's exhalation collected by the air flow sensor B reaches the same as the air flow collected by the air flow sensor A before holding the breath, the processor controls the air pump B to close.

[0023] A further improvement of the present invention is that in step 7), after the contact piece is removed, the inner end surface of the cover body is disinfected by spraying alcohol.

[0024] The beneficial effects of the present invention are: First, the breathing mask specially used for chest and lung imaging examination of the present invention and the method of using the breathing mask detect the patient's breathing condition and remind the patient to hold his breath as required so that the patient's lungs and chest cavity can expand. It is also connected to the console through communication and is convenient for lung and chest imaging examination under the operation cooperation of the console, thereby ensuring the clarity of the lung and chest images and improving the accuracy of the examination.

[0025] Second, the breathing mask specially used for chest and lung imaging examination and the method of using the same of the present invention ensure the cleanliness and hygiene of the patient when using the breathing mask through the function of the contact piece, thereby avoiding cross infection.

[0026] Third, the breathing mask specially used for chest and lung imaging examination and the use method thereof of the present invention are connected to the mask body through the plug-in interface of the air inlet and air outlet of the nose pad through the contact piece, which is convenient for quick plug-in and fixation, thereby improving efficiency.

[0027] Fourth, the breathing mask specially used for chest and lung imaging examination and the use method thereof of the present invention can form a sealed cavity between the mask body and the patient's face through the action of the annular sealing sheet A, the annular sealing sheet B and the annular sealing sheet C, and form a relatively high pressure in the sealed cavity through the air pump A and the air inlet hole. The high pressure in the sealed cavity makes the annular sealing sheet B and the annular sealing sheet C fit the edges of the nostrils and the mouth of the face, thereby preventing the air in the patient's lungs from escaping from the nostrils or the mouth.

[0028] Fifth, the breathing mask specially used for chest and lung imaging examination and the use method thereof of the present invention, through the speaker provided on the ear-hanging rope, not only can the patient hear the reminder of the control console clearly, but also can hear the voice content or other reminder content or music played by the processor of the mask body, thereby eliminating the patient's nervousness and fear and facilitating the patient's cooperation in operation; and the structure of the speaker is compared with the ear-hanging rope, and the contact surface with the ear is larger, so as to avoid the patient's ear being hurt by being strangled.

[0029] Sixth, the breathing mask specially used for chest and lung imaging examination and the use method thereof of the present invention, the two ends of the ear hanging rope are fixed to the outer end surface of the mask body, thereby ensuring the complete fit between the sealing strip at the edge of the inner end surface of the mask body and the face, and further ensuring the sealing effect of the sealing cavity between the mask body and the patient's face.

[0030] Seventh, the breathing mask specially used for chest and lung imaging examinations and the method of using the same of the present invention can prevent the patient from inserting the mouth inlet tube too deeply and causing discomfort through the limit baffle provided on the contact piece, and can also be beneficial to the formation of a sealed cavity between the mask body and the patient's face, making it easy to disassemble and assemble the mouth inlet tube and the air outlet tube.

[0031] Eighth, the breathing mask specially used for chest and lung imaging examination and the using method thereof of the present invention are simple and convenient for patients to use and operate. Patients only need to install the contact pieces, put on the mask body through the ear hanging ropes, breathe and hold their breath according to the voice content and prompt sounds played by the speakers, and finally remove the mask body and separate the contact pieces from the mask body.

[0045] Combination Figure 1~Figure 4 It can be seen that the method for using the breathing mask described above includes the following steps: 1) First, fix the contact piece 11 to the mask body 1, so that the nose pad 14 contacts the top of the nose pad 6, and the tube sleeve 12 is fixed to the corresponding air inlet pipe 7, and the inlet pipe 13 is fixed to the air outlet pipe 8 through the plug interface 9; 2) Then, the mask body 1 is fixed to the face of the patient to be examined by the ear-hanging rope 2, and the nasal plugs 15 are respectively plugged into the patient's nostrils, and the mouth inlet tube 13 is placed in the patient's mouth, and the patient's mouth is closed and pressed against the limit baffle 17, and the speaker 10 is exactly limited to the rear side of the ear-hanging rope 2 and the patient's auricle under the action of the ear-hanging rope 2; 3) After the processor 25 receives the start signal from the console 32 through the communication device 26, the processor 25 controls the one-way valve A29 and the one-way valve B30 to open and the valve 31 to close, and the processor 25 controls the speaker 10 to play the voice content A, so that the patient inhales through the nose and exhales through the mouth, so that the airflow sensor A27 and the airflow sensor B28 respectively collect the airflow information of the patient during breathing and transmit it to the processor 25; 4) The processor 25 controls the speaker 10 to play the voice content B so that the patient can continue to take deep breaths. When the patient fails to complete deep breaths for many times, the processor 25 controls the air pump A4 and the one-way valve B27 to actively intervene to help the patient take deep breaths. When the airflow sensor A27 collects the patient's inspiratory flow information, the processor 25 simultaneously controls the air pump A4 to start and the one-way valve B30 to close. The air pump A4 actively pumps external air into the patient's nasal cavity so that the patient's air intake can meet the air intake required by the patient during the test. When the airflow collected by the airflow sensor A27 is greater than or equal to the air intake required by the patient during the test, the processor 25 simultaneously controls the air pump A4 to close and the one-way valve B30 to open; 5) When the airflow volume of the patient's inhalation in the airflow information collected by the airflow sensor A27 for m consecutive times can stably be greater than or equal to the amount of air inhaled required for the patient's test, but the time interval between the end of the airflow volume collected by the airflow sensor A27 and the airflow information of the patient's exhalation collected by the adjacent airflow sensor B28 is less than the time required for the test, the processor 25 controls the speaker 10 to play the voice content C, so that the patient holds his breath after inhaling through his nose, until the processor 25 controls the speaker 10 to play the exhalation prompt tone, and the time interval between the speaker 10 playing the exhalation prompt tone and the end of the airflow volume collected by the airflow sensor A27 is greater than or equal to the time required for the test; When the airflow sensor B28 collects the patient's exhaled air volume information before the processor 25 controls the speaker 10 to play the exhalation prompt tone, the processor 25 controls the speaker 10 to play the voice content C again before the airflow sensor A27 finishes collecting the patient's inhaled air volume next time, and controls the one-way valve B30 to close, until the processor 25 controls the speaker 10 to play the exhalation prompt tone, and the processor 25 controls the one-way valve B30 to open again; 6) When the patient completes deep breathing for multiple times in succession and the breath-holding time between deep breathing meets the inspection requirements, the processor 25 sends a signal to the console 32 through the communication device 26 that the inspection can be carried out. After the processor 25 receives the inspection signal sent by the console 32 through the communication device 26, when the airflow sensor A27 collects the airflow volume of the patient's inhalation, the processor 25 sends an inspection start signal to the console 32 through the communication device 26 to enable the console 32 to carry out the inspection; 7) When the processor 25 receives a signal indicating that the examination is completed from the console 32 through the communication device 26, the processor controls the speaker 10 to play the voice content D to let the patient know that the examination is over, and then removes the mask 1, separates the contact piece 11 from the mask 1, and places the contact piece 11 in the processing box so that the mask 1 can be used by the next patient.

[0046] In the step 4), when the airflow sensor A27 has collected airflow information for the last 2m consecutive times and the patient's inhaled airflow volume in the airflow information collected for m consecutive times is still not stably greater than or equal to the air inhalation volume required for the patient detection, the processor 25 determines that the patient has been unable to complete deep breathing for multiple times.

[0047] In the step 5), when the airflow volume of the patient's inhalation in the airflow information collected by the airflow sensor A27 for m consecutive times can be stably greater than or equal to the air inhalation volume required for the patient to be tested, the processor 25 determines that the patient has completed deep breathing for multiple consecutive times; when the time interval between the end of the airflow volume collected by the airflow sensor A27 each time and the airflow information of the patient's exhalation collected by the adjacent airflow sensor B28 is less than the time required for the examination, the processor 25 determines that the breath-holding time between deep breaths does not meet the examination requirements.

[0048] In the step 6), when the airflow volume of the patient's inhalation in the airflow information collected by the airflow sensor A27 for m consecutive times can stably be greater than or equal to the amount of air inhaled required for the patient's examination, the processor 25 determines that the patient has completed deep breathing for multiple consecutive times; when the time interval between the end of the airflow volume collected by the airflow sensor A27 each time and the airflow information of the patient's exhalation collected by the adjacent airflow sensor B28 is greater than or equal to the time required for the examination, the processor 25 determines that the breath-holding time between deep breaths meets the examination requirements.

[0049] The m is in the range of 2 to 5 (in this embodiment, m is 4).

[0050] In the step 4), the console 32 sends a signal of forced deep breathing exercise to the processor 25 through the communication device 26. After the processor 25 receives the signal of forced deep breathing exercise, when the airflow sensor A27 collects the patient's inspiratory flow information, the processor 25 simultaneously controls the air pump A4 to start and the one-way valve B30 to close. The air pump A4 actively pumps the outside air into the patient's nasal cavity, so that the airflow collected by the airflow sensor A27 this time is greater than the airflow collected last time; when the airflow collected by the airflow sensor A27 is greater than the airflow collected last time, the processor 25 simultaneously controls the air pump A4 to close and the one-way valve B30 to open; when the airflow sensor B28 collects the patient's inspiratory flow information, the processor 25 simultaneously controls the air pump A4 to close and the one-way valve B30 to open. When the expiratory flow information of the patient is obtained, the processor 25 controls the air pump B5 to start, and the air pump B5 assists the patient to exhale the air in the lungs through the mouth as quickly as possible, and the air flow sensor B28 collects the patient's exhaled air volume; when the air flow sensor A27 collects the patient's inspiratory flow information again, the processor 25 controls the air pump B5 to turn off, and controls the air pump A4 to start and the one-way valve B30 to close at the same time, and repeats this step until the air flow collected by the air flow sensor A27 is greater than or equal to the air inhalation volume required for the patient's detection, so that the amount of air pumped in by the air pump A4 each time thereafter can make the air flow collected by the air flow sensor A27 maintain greater than or equal to the air inhalation volume required for the patient's detection.

[0051] In the step 5), when the air flow collected by the air flow sensor A27 and the air flow collected by the air flow sensor B28 can maintain an air intake amount greater than or equal to the air intake amount required for the patient to be tested, but the breath holding time between multiple deep breaths does not meet the inspection requirements, the processor 25 controls the one-way valve A29 and the one-way valve B30 to close and opens the air pump A4 and the valve 31 after the air flow sensor A27 finishes collecting the air flow, and the air pump A4 pumps the air outside the mask 1 into the mask 1 through the air inlet 18, and then the air is passed through the annular sealing member 19 along the sealing strip 19. The bottom edges of the sheet A20 and the nasal plug 15 are respectively provided with an annular sealing sheet B21 and the edge of the customized baffle 17 is provided with an annular sealing sheet C22, so that a relatively high-pressure sealing cavity is formed between the mask body 1 and the patient's face. The relatively high pressure in the high-pressure sealing cavity makes the annular sealing sheet B21 and the annular sealing sheet C22 fit tightly to the edges of the nostrils and mouth of the patient's face, preventing the air inhaled by the patient from escaping from the nostrils or mouth. At this time, the patient's lungs and chest cavity are kept in the most expanded state, so as to facilitate the clearest image of the chest and lung examination.

[0052] After the processor 25 receives the signal of completing the imaging sent by the console 32 through the communication device 26, the processor 25 controls the air pump A4 to close, and opens the air pump B5 and the one-way valve B30 at the same time. At this time, the air in the patient's lungs can be quickly exhaled with the assistance of the air pump B5, and the air in the high-pressure sealed cavity between the mask body 1 and the patient's face is discharged to the outside from the air inlet end A of the air pump A4 through the trachea B connected to the air inlet hole 18; when the air flow information of the patient's exhalation collected by the air flow sensor B5 reaches the same as the air flow collected by the air flow sensor A4 before holding the breath, the processor 25 controls the air pump B5 to close.

[0053] In the step 7), after the contact piece 11 is removed, the inner end surface of the cover body 1 is disinfected by spraying alcohol.

[0054] In the step 7), when the contact piece 11 is a disposable item, the treatment box where the contact piece 11 is placed after the inspection is a medical waste treatment box; when the contact piece 11 is a reusable item, the treatment box where the contact piece 11 is placed after the inspection is a recycling treatment box, and the recycled contact piece 11 needs to be cleaned, disinfected, sterilized, dried and sealed before it can be used again.

[0055] The set value of the air intake amount required for the patient detection is preset in the processor 25 or the console 32 sends the set value of the air intake amount required for the patient detection to the processor 25 through the communication device 26 .

[0056] The processor 25 controls the speaker 10 to play music when the speaker 10 is not playing voice content, prompt sound or the console 32 is transmitting voice content.

[0057] Those skilled in the art can also utilize some of the functions of the present application to assist unconscious patients in breathing and to assist in the treatment of snoring patients.
