Description

Technical Field

[0001] The invention relates to an oxygen supply mask, in particular to an oxygen supply mask capable of monitoring the respiratory state of a patient. Background Art

[0002] Patients with respiratory failure need to detect the effect of oxygen therapy while receiving oxygen therapy, so as to change the oxygen therapy strategy in a targeted manner. At present, the common measurement of peripheral oxygen saturation blood gas analysis, but these results are all the results of changes in respiratory failure. Clinically, it is very necessary to monitor the changes of a series of respiratory parameters such as respiratory flow rate, respiratory pressure, ventilation volume, etc. in real time to predict the changes in the condition in advance. In order to achieve the above purpose, the existing technology usually sets a sensor in the trachea connected to the oxygen mask, but the existing oxygen mask continues to use the traditional closed design. After being worn on the patient's face, a closed space is formed inside, which will increase airway resistance, repeated inhalation of CO2, and increase dead space ventilation, thereby fundamentally changing the respiratory conditions of the patient's original respiratory system. It can be seen that the design defects of the existing monitoring products directly lead to changes in the basic conditions of the monitored person, causing unpredictable changes in the monitoring parameters, resulting in the invalidity of the monitoring results. This is also the reason why no related products can be used clinically so far. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a respiratory monitoring oxygen supply mask, which, after being worn on the face of a patient (i.e., the wearer), will not affect any original functions and structures of the patient's respiratory system, can truly collect and monitor changes in the patient's respiratory parameters, and can also ensure efficient oxygen supply.

[0004] The respiratory monitoring oxygen supply mask of the present invention comprises a mask body, a nozzle and a sensor. The mask body comprises a central portion opposite to the mouth and nose of the wearer and an edge portion fitted to the face of the wearer, the edge portion being arranged around the periphery of the central portion, a through hole connecting the outer side and the inner side of the mask body is provided between the central portion and the edge portion of the mask body, the central portion protrudes toward the outer side of the mask body to form a diffusion cavity located inside the mask body, a nozzle is connected to the cavity wall of the diffusion cavity, the air inlet and the air outlet of the nozzle are respectively located on the outer side and the inner side of the mask body, and a sensor is provided at the central portion of the inner side of the mask body.

[0005] The respiratory monitoring oxygen supply mask of the present invention, wherein the mask body further comprises a bridging portion, the central portion and the edge portion are connected via the bridging portion, and the through hole is provided on the bridging portion.

[0006] The respiratory monitoring oxygen supply mask of the present invention, wherein the central part is a barrel-shaped structure protruding toward the outside of the mask body, the barrel cavity of the central part is the diffusion cavity, and a nozzle is provided on the barrel bottom wall of the central part.

[0007] The respiratory monitoring oxygen supply mask of the present invention, wherein the sensor is arranged on the inner barrel wall of the central part and / or the part of the nozzle located in the barrel cavity of the central part.

[0008] The respiratory monitoring oxygen supply mask of the present invention, wherein the sensor is arranged on the inner barrel wall of the central part and / or the part of the nozzle located in the barrel cavity of the central part by means of inlay.

[0009] The respiratory monitoring oxygen supply mask of the present invention, wherein the inner barrel wall of the central part is connected with a bracket, the sensor is arranged on the bracket, and the sensor is located inside or outside the barrel cavity of the central part.

[0010] The respiratory monitoring oxygen supply mask of the present invention, wherein the bracket is in the shape of a rod, one end of the bracket is connected to the inner barrel wall of the central part, and the other end of the bracket is provided with a sensor.

[0011] The respiratory monitoring oxygen supply mask of the present invention, wherein the bracket comprises a bearing plate, the bearing plate is provided with supporting legs, the supporting legs are connected to the inner barrel wall of the central part, and the bearing plate is provided with a sensor.

[0012] The respiratory monitoring oxygen supply mask of the present invention, wherein the sensor is at least one of a pressure sensor, a flow rate sensor, a flow sensor and a temperature sensor.

[0013] The difference between the respiratory monitoring oxygen supply mask of the present invention and the prior art is that the conventional oxygen mask adopts a closed design and oxygen is only diffused in the mask without a fixed direction, while the present invention adopts an open design in structure, and utilizes a nozzle and a diffusion chamber designed by fluid mechanics. When the respiratory monitoring oxygen supply mask of the present invention is in use, the mask body is covered on the face of the patient (i.e., the wearer), the edge portion fits the face of the patient, and the central portion faces the mouth and nose of the patient. When the patient inhales, oxygen can be supplied to the mask body through the nozzle, and the oxygen flows through the nozzle and sprays into the diffusion chamber inside the mask body. Since the diffusion chamber is opposite to the patient's mouth and nose (the central part is opposite to the patient's mouth and nose, so the diffusion chamber arranged in the central part is also opposite to the patient's mouth and nose), the patient can be supplied with oxygen in a directional manner. At the same time, since the mask body is provided with a through hole, that is, the oxygen supply mask is an open-type mask, so part of the air enters the inside from the outside of the mask body through the through hole, and then collides with the oxygen flow at the diffusion chamber to form a vortex, that is to say, the present invention can provide directional oxygen vortex oxygen supply to the patient, and the patient's chest opens when inhaling to form a negative pressure in the chest cavity, and oxygen is efficiently inhaled. When the patient exhales, the exhaled CO2 can be directly discharged to the outside of the mask body through the through hole, and there is no problem of repeated inhalation of CO2. It can be seen that when the present invention is used, it can make the patient breathe normally. Compared with the traditional closed oxygen supply mask, it will not increase the airway resistance, will not increase the dead space ventilation, and there will be no repeated inhalation of CO2. It will not affect the patient's original respiratory parameters, that is, it will not have any impact on the basic conditions of the patient's respiratory system. The patient's respiratory system has no external interference. Therefore, the sensor can truly and effectively collect and monitor the changes in the patient's respiratory parameters, prompt the patient's respiratory system function changes, and at the same time ensure efficient oxygen supply.

[0014] The present invention will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 1

[0040] like Figure 1-6 As shown, the respiratory monitoring oxygen supply mask of the present invention includes a mask body, a nozzle 5 and a sensor 7. The mask body includes a central portion 1 opposite to the mouth and nose of the wearer (such as a patient) and an edge portion 3 fitted with the face of the wearer, the edge portion 3 is arranged around the periphery of the central portion 1, and a through hole 6 connecting the outer side and the inner side of the mask body is provided between the central portion 1 and the edge portion 3 of the mask body. The central portion 1 protrudes toward the outside of the mask body to form a diffusion cavity located inside the mask body, and a nozzle 5 is connected to the cavity wall of the diffusion cavity. The air inlet and the air outlet of the nozzle 5 are respectively located on the outer side and the inner side of the mask body, and a deflector 8 is provided at the air outlet of the nozzle 5 (the deflector 8 is a part of the nozzle 5), and a sensor 7 is provided at the central portion 1 inside the mask body.

[0041] The mask body further comprises a bridging portion 2, the central portion 1 and the edge portion 3 are connected by the bridging portion 2, and the bridging portion 2 is provided with the through hole 6. There can be a plurality of through holes 6, and the plurality of through holes 6 are arranged along the circumference of the central portion. The number and size of the through holes 6 can be determined according to actual needs.

[0042] The mask body is in the shape of a groove as a whole, and the groove is used to accommodate the mouth and nose of the wearer. The central part 1 is the bottom of the groove, the edge part 3 is the groove edge of the groove, and the bridge part 2 is the groove side wall of the groove. The side of the mask body provided with the groove is the inner side, and the side of the mask body opposite to the groove is the outer side, and the inner side and the outer side are respectively located on the opposite sides of the mask body.

[0043] The respiratory monitoring oxygen supply mask of the present invention, wherein the central part 1 is a barrel-shaped structure protruding to the outside of the mask body, the barrel cavity of the central part 1 is the diffusion cavity, and a nozzle 5 is provided on the barrel bottom wall of the central part 1. The nozzle 5 is an L-shaped barrel structure, and the two ends of the nozzle 5 are respectively an air inlet end 10 and an air outlet end 11, the barrel mouth of the air inlet end 10 is the air inlet, and the barrel mouth of the air outlet end 11 is the air outlet. An opening is provided on the barrel bottom wall of the central part 1, and the air outlet end 11 of the nozzle 5 is clamped on the opening, so that the air inlet end 10 and the air inlet of the nozzle 5 are located on the outside of the mask body, and the air outlet end 11 and the air outlet are located on the inside of the mask body.

[0044] When supplying oxygen, the air inlet end 10 of the nozzle 5 is connected to the oxygen supply pipe, and oxygen enters the nozzle 5 from the air inlet of the nozzle 5, and then is sprayed into the inner side of the mask body, specifically into the diffusion cavity, from the air outlet of the nozzle 5. In order to evenly distribute the oxygen from the nozzle 5 in the diffusion cavity, a deflector 8 is provided at the air outlet of the nozzle 5 (the deflector 8 is located in the diffusion cavity, or it can be said that the deflector 8 is located in the barrel cavity of the central part 1). The oxygen flow sprayed from the air outlet of the nozzle 5 is sprayed on the deflector 8. Under the dispersion and guiding effect of the deflector 8, the oxygen flow diffuses around with the deflector 8 as the center, and finally evenly distributes in the diffusion cavity.

[0045] When the deflector 8 is specifically arranged, the deflector 8 is fixedly arranged at one end of a support 9, and the other end of the support 9 is inserted into the gas outlet of the nozzle 5 and fixed on the inner cylinder wall of the nozzle 5. The diameter of the support 9 is smaller than the inner cylinder diameter of the nozzle 5, so that the support 9 will not affect the flow of oxygen through the nozzle 5, and the deflector 8 can be arranged directly opposite to the gas outlet of the nozzle 5, so that the oxygen flow ejected from the gas outlet of the nozzle 5 is just sprayed on the deflector 8.

[0046] The shape of the deflector 8 may be a mushroom head shape, an umbrella shape or a bowl shape, and of course may also be other shapes that can disperse and guide the oxygen flow.

[0047] The bridge portion 2 and the edge portion 3 are both annular, the barrel mouth of the central portion 1 is connected to the inner edge of the bridge portion 2, and the outer edge of the bridge portion 2 is connected to the inner edge of the edge portion 3. The central portion 1, the bridge portion 2 and the edge portion 3 are an integrally formed structure. The bridge portion 2 is provided with a plurality of through holes 6, and the plurality of through holes 6 are arranged along the circumference of the bridge portion 2. Since the bridge portion 2 surrounds the periphery of the central portion 1, the plurality of through holes 6 are arranged along the circumference of the central portion 1. The number and size of the through holes 6 on the bridge portion 2 can be determined according to actual needs. When the oxygen supply mask is used, the inner side of the mask body faces the patient (i.e., the wearer) and covers the patient's face. At this time, the edge portion 3 fits the patient's face, and the central portion 1 is opposite to the patient's mouth and nose. In this way, the barrel cavity (i.e., the diffusion cavity) of the central portion 1 is also opposite to the patient's mouth and nose, and the sensor 7 provided at the central portion 1 is also opposite to the patient's mouth and nose.

[0048] Of course, when the oxygen supply mask is used, an ear 4 is provided on the left and right sides of the edge portion 3, and straps are connected to the two ears 4, so that the oxygen supply mask is fixed on the patient's face through the straps.

[0049] like Figure 4-6As shown, in the respiratory monitoring oxygen supply mask of the present invention, the sensor 7 is arranged on the inner barrel wall of the central part 1 by means of inlay, specifically on the inner barrel side wall or the inner barrel bottom wall. The sensor 7 is at least one of a pressure sensor, a flow rate sensor, a flow sensor and a temperature sensor, and the sensor 7 is set to be one, and the sensor 7 is a pressure sensor, a flow rate sensor, a flow sensor or a temperature sensor.

[0050] Since the sensor 7 is arranged on the inner barrel wall of the central part 1, it can be regarded as a specific implementation of the central part 1 as mentioned above. Since the central part 1 is opposite to the patient's mouth and nose after the oxygen mask is worn on the patient's face, the sensor 7 can accurately collect and monitor the patient's respiratory parameters, that is, when the sensor 7 is a pressure sensor, a flow rate sensor, a flow sensor or a temperature sensor, it can collect and monitor the pressure, flow rate, flow rate or temperature of the patient's exhaled and inhaled gas. The sensor 7 is connected to the control device by wire or wireless means, and the control device can record the changing trend of pressure, flow rate, flow rate or temperature over time.

[0051] The difference between the respiratory monitoring oxygen supply mask of the present invention and the prior art is that the conventional oxygen mask adopts a closed design and oxygen is only diffused in the mask without a fixed direction, while the present invention adopts an open design in structure, and utilizes a nozzle 5 and a diffusion chamber designed by fluid mechanics. When the respiratory monitoring oxygen supply mask of the present invention is in use, the mask body is covered on the face of the patient (i.e., the wearer), the edge portion 3 fits the face of the patient, and the central portion 1 is opposite to the mouth and nose of the patient. When the patient inhales, oxygen can be supplied to the mask body through the nozzle 5. The oxygen flow is sprayed onto the deflector 8 on the inner side of the mask body through the nozzle 5. Through the dispersion and guidance of the deflector 8, the oxygen flow diffuses around the deflector 8 and is evenly distributed in the diffusion cavity. Since the diffusion cavity is opposite to the patient's mouth and nose (the central part 1 is opposite to the patient's mouth and nose, so the diffusion cavity provided in the central part 1 is also opposite to the patient's mouth and nose), the patient can be supplied with oxygen in a directional manner. At the same time, since the bridge part 2 is provided with a through hole 6, that is, the oxygen supply mask is an open-type mask, so part of the air enters the inner side from the outer side of the mask body through the through hole 6, and then collides with the oxygen flow at the diffusion cavity to form a vortex. In other words, the present invention can provide directional oxygen vortex oxygen supply to the patient. When the patient inhales, the chest cavity opens to form a negative pressure in the chest cavity, and oxygen is efficiently inhaled. When the patient exhales, the exhaled CO2 can be directly discharged to the outer side of the mask body through the through hole 6, and there is no problem of repeated inhalation of CO2. It can be seen that when the present invention is used, it can make the patient breathe normally. Compared with the traditional closed oxygen supply mask, it will not increase the airway resistance, will not increase the dead space ventilation, and there will be no repeated inhalation of CO2. It will not affect the patient's original respiratory parameters, that is, it will not have any impact on the basic conditions of the patient's respiratory system. The patient's respiratory system has no external interference. Therefore, the sensor 7 can truly and effectively collect and monitor the changes in the patient's respiratory parameters, prompt the patient's respiratory system function changes, and at the same time ensure efficient oxygen supply.

[0052] Embodiment 2

[0053] like Figure 7 As shown, the difference between this embodiment and the first embodiment is that the number of sensors 7 is different, that is, the number of sensors 7 of this embodiment is set to two, and the two sensors 7 are both arranged on the inner barrel wall of the central part 1 by inlay. The two sensors 7 can be the same or different, that is, the two sensors 7 can be any one or any two of a pressure sensor, a flow rate sensor, a flow sensor and a temperature sensor. When the two sensors 7 are different, the two sensors 7 can simultaneously collect and monitor two respiratory parameters of the patient, that is, any two of the pressure, flow rate, flow rate and temperature of the patient's exhaled and inhaled gas. When the two sensors 7 are the same, the two sensors 7 can simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0054] Embodiment 3

[0055] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that the number of sensors 7 is different, that is, the number of sensors 7 in this embodiment is set to three, and the three sensors 7 are all arranged on the inner barrel wall of the central part 1 by inlay. The three sensors 7 can be the same or different, that is, the three sensors 7 can be any one or any two or any three of the pressure sensor, flow rate sensor, flow sensor and temperature sensor. In this way, the three sensors 7 can collect and monitor any one or any two or any three of the pressure, flow rate, flow rate and temperature of the patient's exhaled and inhaled gas. When two or more sensors 7 among the three sensors 7 are the same, two or more identical sensors 7 can simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0056] Of course, the number of sensors 7 can also be set to four, and the four sensors 7 are all arranged on the inner barrel wall of the central part 1 by inlay. The four sensors 7 can be the same or different, that is, the four sensors 7 can be any one or any two or any three of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor, or the four sensors 7 are respectively a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. In this way, the four sensors 7 can collect and monitor any one or any two or any three of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas, or the pressure, flow rate, flow rate, and temperature can be collected and monitored at the same time. When two or more sensors 7 are the same among the four sensors 7, more than two identical sensors 7 can be allowed to collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient at the same time, and then the average value is calculated, so that the collection and monitoring results are more accurate.

[0057] Embodiment 4

[0058] like Figure 9-11 As shown, the difference between this embodiment and the first embodiment is that the sensor 7 is set at a different position. In this embodiment, the sensor 7 is set on the part of the nozzle 5 located in the barrel cavity of the central part 1 by means of inlay, and specifically, the sensor 7 is set on the baffle 8 by means of inlay. Since the baffle 8 is a part of the nozzle 5 and the baffle 8 is located in the barrel cavity of the central part 1, setting the sensor 7 on the baffle 8 is a specific implementation method of setting the sensor 7 on the part of the nozzle 5 located in the barrel cavity of the central part 1.

[0059] The sensor 7 is set to be one, and the sensor 7 is a pressure sensor, a flow rate sensor, a flow sensor or a temperature sensor.

[0060] Since the deflector 8 is arranged in the diffusion cavity, that is, in the barrel cavity of the central part 1, and the sensor 7 is arranged on the deflector 8, it can be regarded as a specific implementation method of arranging the sensor 7 at the central part 1.

[0061] Embodiment 5

[0062] like Fig.12 As shown, the difference between this embodiment and the fourth embodiment is that the number of sensors 7 is different. In this embodiment, two sensors 7 are provided, and both sensors 7 are provided on the deflector 8 by inlay. The two sensors 7 may be the same or different, that is, the two sensors 7 may be any one or any two of a pressure sensor, a flow rate sensor, a flow sensor and a temperature sensor. When the two sensors 7 are different, the two sensors 7 may simultaneously collect and monitor two respiratory parameters of the patient, that is, any two of the pressure, flow rate, flow rate and temperature of the patient's exhaled and inhaled gas. When the two sensors 7 are the same, the two sensors 7 may simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0063] Embodiment 6

[0064] like Fig.13 As shown, the difference between this embodiment and the fourth embodiment is that the number of sensors 7 is different. In this embodiment, the number of sensors 7 is three, and the three sensors 7 are all arranged on the deflector 8 by inlay. The three sensors 7 can be the same or different, that is, the three sensors 7 can be any one, any two, or any three of the pressure sensor, the flow rate sensor, the flow sensor, and the temperature sensor. In this way, the three sensors 7 can collect and monitor any one, any two, or any three of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas. When two or more of the three sensors 7 are the same, two or more of the same sensors 7 can simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0065] Of course, the number of sensors 7 can also be set to four, and the four sensors 7 are all set on the deflector 8 by inlay. The four sensors 7 can be the same or different, that is, the four sensors 7 can be any one or any two or any three of the pressure sensor, flow rate sensor, flow sensor and temperature sensor, or the four sensors 7 can be pressure sensor, flow rate sensor, flow sensor and temperature sensor respectively. In this way, the four sensors 7 can collect and monitor any one or any two or any three of the pressure, flow rate, flow rate and temperature of the patient's exhaled and inhaled gas, or the pressure, flow rate, flow rate and temperature can be collected and monitored at the same time. When two or more sensors 7 are the same among the four sensors 7, more than two of the same sensors 7 can collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate or temperature) of the patient at the same time, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0066] Embodiment 7

[0067] like Figure 14-16 As shown, the difference between this embodiment and embodiment 1 is that the sensor 7 is arranged on the inner barrel wall of the central part 1 through the bracket 12. Specifically, the bracket 12 is connected to the inner barrel wall of the central part 1, and the sensor 7 is arranged on the bracket 12. The sensor 7 is located inside or outside the barrel cavity of the central part 1.

[0068] In this embodiment, the bracket 12 includes four legs 13, one end of the four legs 13 is fixedly connected to the inner barrel side wall of the central part 1, and one end of the four legs 13 is arranged at intervals along the circumferential direction of the inner barrel side wall of the central part 1, and the other ends of the four legs 13 are gathered at one point and fixedly connected to the sensor 7. The sensor 7 can be located in the barrel cavity of the central part 1, or it can be located outside the barrel cavity. In either case, it can be regarded as a specific implementation method of providing the sensor 7 at the central part 1. The sensor 7 is set to one, and the sensor 7 is a pressure sensor, a flow rate sensor, a flow sensor or a temperature sensor.

[0069] Of course, the specific structure of the bracket 12 may also adopt other forms, as long as the sensor 7 can be fixed on the inner barrel side wall of the central part 1.

[0070] Embodiment 8

[0071] like Fig.17 As shown, the difference between this embodiment and embodiment seven is the number of sensors 7. In this embodiment, two sensors 7 are provided, and the specific arrangement is as follows: the bracket 12 includes a supporting plate 14, the supporting plate 14 is provided with a supporting leg 13, the supporting leg 13 is connected to the inner barrel wall of the central portion 1, and the supporting plate 14 is provided with a sensor 7.

[0072] In order to facilitate the installation of the sensor 7, compared with the seventh embodiment, the bracket 12 of this embodiment is additionally provided with a bearing plate 14, one end of the four legs 13 is fixedly connected to the inner barrel wall of the central part 1, and the other ends of the four legs 13 are gathered at one point and fixedly connected to the bearing plate 14, and two sensors 7 are arranged on the bearing plate 14. Of course, the specific structure of the bracket 12 can also adopt other forms, as long as the sensor 7 can be fixedly arranged on the inner barrel side wall of the central part 1.

[0073] The two sensors 7 may be the same or different, that is, the two sensors 7 may be any one or any two of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. When the two sensors 7 are different, the two sensors 7 may simultaneously collect and monitor two respiratory parameters of the patient, that is, any two of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas. When the two sensors 7 are the same, the two sensors 7 may simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0074] Embodiment 9

[0075] like Fig.18 As shown, the difference between this embodiment and the eighth embodiment lies in the number of sensors 7 . In this embodiment, three sensors 7 are disposed on the carrying plate 14 .

[0076] The three sensors 7 may be the same or different, that is, the three sensors 7 may be any one, any two, or any three of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. In this way, the three sensors 7 may collect and monitor any one, any two, or any three of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas. When two or more of the three sensors 7 are the same, two or more of the same sensors 7 may simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0077] Of course, the number of sensors 7 can also be set to four, and the four sensors 7 are all arranged on the carrier plate 14. The four sensors 7 can be the same or different, that is, the four sensors 7 can be any one or any two or any three of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor, or the four sensors 7 are respectively a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. In this way, the four sensors 7 can collect and monitor any one or any two or any three of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas, or the pressure, flow rate, flow rate, and temperature can be collected and monitored simultaneously. When more than two sensors 7 are the same among the four sensors 7, more than two identical sensors 7 can be allowed to collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient at the same time, and then averaged, so that the collection and monitoring results are more accurate.

[0078] Embodiment 10

[0079] like Figure 19-21 As shown, the difference between this embodiment and the first embodiment is that the sensor 7 is arranged on the inner barrel wall of the central part 1 through the bracket 12. Specifically, the bracket 12 is rod-shaped, one end of the bracket 12 is connected to the inner barrel wall of the central part 1, and the other end of the bracket 12 is provided with the sensor 7.

[0080] In this embodiment, one end of the rod-shaped bracket 12 is fixedly connected to the inner barrel bottom wall of the central part 1, and the other end of the bracket 12 is provided with a sensor 7, which can be located in the barrel cavity of the central part 1 or outside the barrel cavity. In either case, it can be regarded as a specific implementation of providing the sensor 7 at the central part 1. The sensor 7 is set to one, and the sensor 7 is a pressure sensor, a flow rate sensor, a flow sensor or a temperature sensor. Of course, the specific structure of the bracket 12 can also adopt other forms, as long as the sensor 7 can be fixedly provided on the inner barrel bottom wall of the central part 1.

[0081] Embodiment 11

[0082] like Fig. 22 As shown, the difference between this embodiment and the tenth embodiment is the number of sensors 7. In this embodiment, two sensors 7 are provided, and the two sensors 7 are respectively fixed on the bottom wall of the inner barrel of the central part 1 through rod-shaped brackets 12.

[0083] The two sensors 7 may be the same or different, that is, the two sensors 7 may be any one or any two of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. When the two sensors 7 are different, the two sensors 7 may simultaneously collect and monitor two respiratory parameters of the patient, that is, any two of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas. When the two sensors 7 are the same, the two sensors 7 may simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0084] Embodiment 12

[0085] like Fig.23 As shown, the difference between this embodiment and the tenth embodiment is the number of sensors 7. In this embodiment, three sensors 7 are provided, and the three sensors 7 are respectively fixed on the bottom wall of the inner barrel of the central part 1 through rod-shaped brackets 12.

[0086] The three sensors 7 may be the same or different, that is, the three sensors 7 may be any one, any two, or any three of a pressure sensor, a flow rate sensor, a flow sensor, and a temperature sensor. In this way, the three sensors 7 may collect and monitor any one, any two, or any three of the pressure, flow rate, flow rate, and temperature of the patient's exhaled and inhaled gas. When two or more of the three sensors 7 are the same, two or more of the same sensors 7 may simultaneously collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate, or temperature) of the patient, and then calculate the average value, so that the collection and monitoring results are more accurate.

[0087] Of course, the number of sensors 7 can also be set to four, and the four sensors 7 are fixed on the bottom wall of the inner barrel of the central part 1 through the rod-shaped bracket 12. The four sensors 7 can be the same or different, that is, the four sensors 7 can be any one or any two or any three of the pressure sensor, flow rate sensor, flow sensor and temperature sensor, or the four sensors 7 are pressure sensors, flow rate sensors, flow sensors and temperature sensors. In this way, the four sensors 7 can collect and monitor any one or any two or any three of the pressure, flow rate, flow rate and temperature of the patient's exhaled and inhaled gas, or the pressure, flow rate, flow rate and temperature can be collected and monitored at the same time. When two or more sensors 7 are the same among the four sensors 7, more than two identical sensors 7 can collect and monitor a certain respiratory parameter (such as pressure, flow rate, flow rate or temperature) of the patient at the same time, and then the average value is calculated, so that the collection and monitoring results are more accurate.

[0088] Embodiment 13

[0089] like Fig.24As shown, the difference between this embodiment and the twelfth embodiment is that the sensor 7 is set at a different position. In this embodiment, when there are three sensors 7, the first sensor 7 is fixedly set on the inner barrel bottom wall of the central part 1 through a rod-shaped bracket 12, the second sensor 7 is fixedly set on the inner barrel side wall of the central part 1 by inlaying, and the third sensor 7 is fixedly set on the baffle 8 by inlaying. Such a setting of three sensors 7 can be regarded as a specific implementation method of providing sensors 7 at the central part 1, and the sensors 7 are simultaneously provided on the inner barrel wall of the central part 1 and the part of the nozzle 5 located in the barrel cavity of the central part 1 (i.e., the baffle 8).

[0090] When there are four sensors 7 , on the basis of the above-mentioned arrangement of the three sensors 7 , the fourth sensor 7 may be arranged on the inner barrel wall of the central portion 1 or on the deflector 8 .
