Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia components, in particular to an anesthetic atomizer and a breathing mask. Background Art

[0002] In medical practice, especially in scenarios like endoscopy and orthopedic surgery (without general anesthesia and intubation), where patients lack breathing tubes for assisted ventilation, the proper use of respiratory masks is crucial for ensuring patient breathing safety. In these scenarios, respiratory masks are not only a key channel for patients to obtain oxygen or anesthetic gases, but also must ensure wearing comfort and a tight seal to reduce pressure damage to the patient's face and prevent gas leakage that could affect treatment effectiveness.

[0003] During clinical operations, it is sometimes difficult for medical staff to directly observe the patient's oral, facial or thoracic movements to determine their respiratory status. Especially during endoscopic examinations or orthopedic surgeries in certain specific body positions, the patient's body position or operating space limits the medical staff's field of view. By monitoring and analyzing the changes in the components of the patient's exhaled gas through end-tidal waveforms, the waveform can be drawn to determine the patient's respiratory rate, depth, and whether there is apnea. Without intubation, a breathing mask can be connected to an end-tidal monitoring instrument, and the end-tidal waveform can be used to determine whether the patient is breathing, providing medical staff with a convenient and effective means of respiratory monitoring. Therefore, those skilled in the art have provided a solution for an anesthetic nebulizer and a breathing mask. Summary of the Invention

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0021] Embodiment 1: A breathing mask comprises a mask mechanism 1, wherein an inflatable decompression lining strip 2 is fixedly connected to the edge of the bottom end face of the mask mechanism 1; the mask mechanism 1 comprises an oxygen inhalation mask 11, an air leakage tube 12 fixed to the left side of the top of the oxygen inhalation mask 11, an end-tidal monitoring tube 13 fixed to the front side of the top of the oxygen inhalation mask 11, and an anesthetic gas source tube 17 connected to the center position of the top of the oxygen inhalation mask 11; the interior of the air leakage tube 12 is blocked with a silicone column 111, the inner cavity of the end-tidal monitoring tube 13 is blocked with a silicone sealing block 110, and the inner cavity of the anesthetic gas source tube 17 is blocked with a silicone plug 18; a ventilator gas source tube 114 is fixed to the rear side of the oxygen inhalation mask 11, and a ventilator gas source nozzle 115 is connected to the interior of the ventilator gas source nozzle 115; wherein, when the ventilator gas source nozzle 115 is connected to the gas source for ventilation, the silicone plug 18 blocks the anesthetic gas source tube 17. The silicone column 111 is pulled out by the pulling strip 112, so that the carbon dioxide gas is discharged from the leak port 15 through the leak tube 12. During combined general anesthesia, the ventilator gas source tube is closed and the anesthetic gas source tube 17 is connected to the ventilator for volatile anesthesia to obtain a certain analgesic and sedative effect, which is conducive to the patient's comfort treatment.

[0022] The top port of the end-of-tidal monitoring tube 13 is connected to the pipeline of the end-of-tidal monitoring instrument, and the top port of the anesthetic gas source tube 17 is connected to the delivery port of the anesthetic atomization equipment through a pipeline; the inflatable decompression lining strip 2 includes a hollow silicone strip 21, an inflation and deflation port 22 fixed on the front side of the top surface of the hollow silicone strip 21, and a chamber 23 opened inside the hollow silicone strip 21.

[0023] In medical scenarios, medical staff use respiratory masks on patients. The oxygen mask 11 of the respiratory mask is made of transparent medical-grade plastic, and a circle of edge strips is fixedly connected to the edge of its bottom end face. The bottom surface of the edge strip is fixedly connected to the top surface of the hollow silicone strip 21 by medical adhesive. The length of the hollow silicone strip 21 is adapted to the bottom edge of the oxygen mask 11, and its internal chamber 23 can be inflated and deflated through the inflation and deflation nozzle 22. The inflation and deflation nozzle 22 is connected to a medical inflation pump at one end away from the hollow silicone strip 21. Medical staff inflate the hollow silicone strip 21 through the inflation pump according to the patient's facial contour, so that the hollow silicone strip 21 expands and fits the patient's face. At the same time, several flexible pressure sensors embedded on the bottom surface of the hollow silicone strip 21 can monitor the extrusion pressure of the mask on the face in real time, and stop inflation when the pressure reaches the appropriate range. The oxygen mask 11 has a leak port 15 on the left side of its top, through which the leaking tube 12 passes. The leaking tube 12 is a rigid plastic tube, and a silicone column 111 is sealed inside it to block the leaking tube 12 when leakage is not required. A pull strip 112 is fixedly connected to the top surface of the silicone column 111. The pull strip 112 is made of elastic plastic, and its end away from the silicone column 111 is fixedly connected to the outer surface of the leaking tube 12. When leakage is required, medical personnel can pull the pull strip 112 to pull the silicone column 111 out of the leaking tube 12, allowing the carbon dioxide gas in the inner cavity of the oxygen mask 11 to escape to the outside.

[0024] Example 2: The top front side of the oxygen mask 11 is provided with an end-of-expiratory monitoring port 16 for the end-of-expiratory monitoring tube 13 to pass through and be fixed. The end-of-expiratory monitoring tube 13 is a transparent plastic tube, and the silicone sealing block 110 sealed in its inner cavity is used to block the end-of-expiratory monitoring tube 13 when end-of-expiratory monitoring is not needed. A plastic connecting strip 19 is fixedly connected to the top surface of the silicone sealing block 110. The plastic connecting strip 19 is made of soft plastic material, and its end away from the silicone sealing block 110 is fixedly connected to the outer surface of the end-of-expiratory monitoring tube 13. When end-of-expiratory monitoring is required, medical staff can pull the plastic connecting strip 19 to pull the silicone sealing block 110 out of the end-of-expiratory monitoring tube 13, and then connect the top port of the end-of-expiratory monitoring tube 13 to the pipeline of the end-of-expiratory monitoring instrument. The anesthetic gas source tube 17 is a hard plastic tube, and the silicone plug 18 sealed in its inner cavity is used to block the anesthetic gas source tube 17 when anesthetic gas delivery is not required. The top of the silicone plug 18 is fixedly connected to the gas source tube sealing plug 14, which is placed over the top port of the anesthetic gas source tube 17. The gas source tube sealing plug 14 is made of silicone, and a plastic strip 113 is fixedly connected to its outer sidewall. The plastic strip 113 is made of elastic plastic, and its end away from the gas source tube sealing plug 14 is fixedly connected to the top sidewall of the oxygen mask 11. The interior of the silicone plug 18 is provided with a cavity that allows the silicone plug 18 to deform inward or outward. A gap is provided between the outer surface of the silicone plug 18 and the inner sidewall of the gas source tube sealing plug 14 for the top port of the anesthetic gas source tube 17 to be inserted. When anesthetic gas needs to be delivered, medical personnel pull the plastic strip 113 to remove the gas source tube sealing plug 14 and the silicone plug 18 from the anesthetic gas source tube 17. The top port of the anesthetic gas source tube 17 is then connected to the delivery port of the anesthetic atomizer through a pipeline. The bottom ends of the end-of-tidal monitoring tube 13 and the air leakage tube 12 are both flush with the inner side wall curved surface of the oxygen inhalation mask 11 to avoid irritation to the patient's face.

[0025] Example 3: The oxygen mask 11 has a band fixedly attached to the bottom edge of its face. The bottom surface of the band is fixedly connected to the top surface of the hollow silicone strip 21 via adhesive. Strap buckles 117 are fixedly attached to the left and right sidewalls of the oxygen mask 11. An elastic band 116 is connected between the band buckles 117 and is wrapped around the patient's head. After the anesthetic gas source tube 17 is connected to the anesthesia machine nebulizer, the band 116 is attached using the band buckles 117. Band 116 wraps around the patient's head, and the elasticity of the band keeps the mask securely fastened to the patient's face, preventing hand pressure during anesthesia breathing. In another medical scenario, the oxygen mask 11 of a respiratory mask is also made of transparent medical-grade plastic. A band made of soft medical rubber is fixedly attached to the bottom edge of its face. The bottom surface of the band is tightly fixed to the top surface of the hollow silicone strip 21 via medical adhesive. The hollow silicone strip 21 is made of a highly elastic and soft silicone material, and its internal chamber 23 can be precisely inflated and deflated through the inflation and deflation nozzle 22. The connection between the inflation and deflation nozzle 22 and the hollow silicone strip 21 is sealed with sealant to prevent air leakage. When it is necessary to wear a mask for the patient, the medical staff first places the mask on the patient's face, and then inflates the hollow silicone strip 21 with air through the air pump. According to the pressure data fed back by the flexible pressure sensor, the inflation volume is adjusted to make the mask fit tightly to the patient's face, while avoiding damage to the patient's face caused by excessive pressure. A leakage port 15 is provided on the left side of the top of the oxygen mask 11 for the leakage tube 12 to pass through, which is used to allow the carbon dioxide gas in the inner cavity of the oxygen mask 11 to escape to the outside. An end-of-tidal monitoring port 16 is provided on the front side of the top of the oxygen mask 11 for the end-of-tidal monitoring tube 13 to pass through and be fixed. During respiratory therapy, the air leakage port 15 on the left side of the top of the oxygen mask 11 of the respiratory mask and the end-tidal monitoring port 16 on the front side of the top are made of precision processing technology to ensure close fit with the air leakage tube 12 and the end-tidal monitoring tube 13. The air leakage tube 12 is a cylindrical hard plastic tube, the outer diameter of which is adapted to the inner diameter of the air leakage port 15 and is fixedly connected by a sealant. The end-tidal monitoring tube 13 is also a cylindrical hard plastic tube, the outer diameter of which is adapted to the inner diameter of the end-tidal monitoring port 16 and is also fixedly connected by a sealant. When the patient breathes and produces carbon dioxide, the carbon dioxide gas can escape to the outside through the air leakage port 15 and the air leakage tube 12. When end-tidal monitoring is required, the medical staff connects the end-tidal monitoring tube 13 to the pipeline of the end-tidal monitoring instrument to monitor the patient's end-tidal carbon dioxide concentration in real time.

[0026] The top of the silicone plug 18 is fixedly connected to the gas source tube sealing plug 14 that is sleeved on the top port of the anesthesia gas source tube 17. The interior of the silicone plug 18 is provided with a cavity for the silicone plug 18 to deform inward or outward. There is a gap between the outer ring surface of the silicone plug 18 and the inner cavity side wall of the gas source tube sealing plug 14 for the top port of the anesthesia gas source tube 17 to be inserted. During anesthesia treatment, the silicone plug 18 of the respiratory mask is made of highly elastic silicone material. The cavity provided therein allows the silicone plug 18 to deform inward or outward when subjected to external force. The gas source tube sealing plug 14 is also made of silicone material. The gap formed between the inner cavity side wall and the outer ring surface of the silicone plug 18 facilitates the insertion of the top port of the anesthesia gas source tube 17. When anesthetic gas is not needed, the silicone plug 18 and the gas source tube sealing plug 14 tightly seal the anesthesia gas source tube 17 to prevent gas leakage. When anesthetic gas delivery is required, medical personnel pull the gas source tube sealing plug 14 and the silicone plug 18 out of the anesthetic gas source tube 17, then connect the top port of the anesthetic gas source tube 17 to the delivery port of the anesthetic atomizer, allowing the anesthetic gas to smoothly enter the inner cavity of the oxygen mask 11 and provide anesthesia to the patient. A plastic strip 113 is fixedly connected to the outer surface side wall of the gas source tube sealing plug 14. The end of the plastic strip 113 away from the gas source tube sealing plug 14 is fixedly connected to the top surface side wall of the oxygen mask 11. In the anesthesia treatment scenario, the plastic strip 113 fixedly connected to the outer surface side wall of the gas source tube sealing plug 14 of the respiratory mask is made of a plastic material with a certain degree of elasticity and flexibility. The end of the plastic strip 113 away from the gas source tube sealing plug 14 is fixedly connected to the top surface side wall of the oxygen mask 11 by strong glue. When medical personnel need to pull out the gas source tube sealing plug 14 and the silicone plug 18, the plastic strip 113 can play a pulling role, facilitating operation. Meanwhile, the length of the plastic strip 113 can be designed according to actual needs to avoid being too long or too short to affect the operation. When it is not necessary to use the anesthesia gas source tube 17, the plastic strip 113 can sag naturally and can not interfere with the normal use of the mask.

[0027] Example 4: A plastic connecting strip 19 is fixedly connected to the top surface of the silicone sealing block 110, and the end of the plastic connecting strip 19 away from the silicone sealing block 110 is fixedly connected to the outer surface of the end-of-expiratory monitoring tube 13. During the respiratory monitoring process, the plastic connecting strip 19 fixedly connected to the top surface of the silicone sealing block 110 of the respiratory mask is made of a soft plastic material. The end of the plastic connecting strip 19 away from the silicone sealing block 110 is fixedly connected to the outer surface of the end-of-expiratory monitoring tube 13 by glue. When medical staff need to pull out the silicone sealing block 110 for end-of-expiratory monitoring, the plastic connecting strip 19 can play a pulling role, which is convenient for operation. The length of the plastic connecting strip 19 is moderate, which can ensure the convenience of the pulling operation, but will not be too long to cause shaking in the mask and affect the monitoring effect. When end-of-expiratory monitoring is not needed, the plastic connecting strip 19 can droop naturally and will not interfere with the normal use of the end-of-expiratory monitoring tube 13.

[0028] The bottom ends of the end-tidal monitoring tube 13 and the leakage tube 12 are both flush with the inner side wall curve of the oxygen mask 11. During respiratory therapy, the bottom ends of the end-tidal monitoring tube 13 and the leakage tube 12 of the respiratory mask are processed so that they fit perfectly and flush with the inner side wall curve of the oxygen mask 11. The bottom ends of the end-tidal monitoring tube 13 and the leakage tube 12 are made of smooth plastic material to avoid irritation to the patient's face. When the patient wears the mask to breathe, the bottom ends of the end-tidal monitoring tube 13 and the leakage tube 12 will not affect the comfort of the patient's face, while ensuring the smooth escape of carbon dioxide gas and the normal operation of end-tidal monitoring. A pull strip 112 is fixedly connected to the top surface of the silicone column 111, and the end of the pull strip 112 away from the silicone column 111 is fixedly connected to the outer surface of the leakage tube 12. In the respiratory therapy scenario, the pull strip 112 fixedly connected to the top surface of the silicone column 111 of the respiratory mask is made of a plastic material with a certain elasticity. The end of the pull strip 112 away from the silicone column 111 is fixedly connected to the outer surface of the leakage tube 12 by glue. When medical staff need to pull out the silicone column 111 to perform leakage operation, the pull strip 112 can play a pulling role, which is convenient for operation. The length of the pull strip 112 can be designed according to actual needs to ensure smooth operation when pulling out the silicone column 111, and at the same time it will not be too long to affect the overall appearance and use of the mask. When leakage is not required, the pull strip 112 can droop naturally and will not interfere with the normal use of the leakage tube 12.

[0029] Example 5: The front top surface of the hollow silicone strip 21 is provided with an opening through which the inflation / deflation nozzle 22 passes and is secured. A sealing ring is secured within the opening. The end of the inflation / deflation nozzle 22, distal from the hollow silicone strip 21, is connected to a medical air pump. Several flexible pressure sensors are embedded on the bottom surface of the hollow silicone strip 21 to monitor the pressure exerted by the mask on the face. During the medical mask application process, the opening on the front top surface of the hollow silicone strip 21 of the respiratory mask is machined to ensure smooth insertion and securement of the inflation / deflation nozzle 22. The sealing ring secured within the opening is made of a highly elastic rubber material to effectively prevent gas leakage. The end of the inflation / deflation nozzle 22, distal from the hollow silicone strip 21, is connected to a medical air pump via a pipe, allowing medical personnel to control the inflation level of the hollow silicone strip 21. Several flexible pressure sensors embedded on the bottom surface of the hollow silicone strip 21 can monitor the squeezing pressure of the mask on the face in real time and transmit the data to the monitoring equipment, making it convenient for medical staff to adjust the inflation volume according to the data to ensure the comfort and safety of patients wearing the mask.

[0030] Example 6: An anesthetic nebulizer includes an anesthetic nebulizer 3, which includes an electric heating plate 31 fixed to the bottom of the inner cavity of an anesthetic gas source tube 17, and an atomizing plate 32 fixed to the top area of the inner cavity of the anesthetic gas source tube 17. The electric heating plate 31 is provided with a plurality of through-holes arranged in a circular array for the circulation of the atomized anesthetic agent. The atomizing plate 32 is provided with a plurality of atomizing holes arranged in a circular array for atomizing larger anesthetic droplets. During anesthesia treatment, the anesthetic nebulizer 3, which is suitable for use with a breathing mask, is installed on the anesthetic gas source tube 17. The electric heating plate 31 of the anesthetic nebulizer 3 is made of a high-temperature resistant and highly conductive material. The plurality of through-holes arranged in a circular array within the anesthetic nebulizer 3 are of appropriate size to ensure smooth circulation of the atomized anesthetic agent. The atomizing plate 32 is made of a highly wear-resistant material. The plurality of atomizing holes arranged in a circular array within the atomizing plate 32 are provided to effectively atomize larger anesthetic droplets. When the anesthetic atomization device delivers the anesthetic solution to the anesthetic gas source tube 17, the anesthetic solution is first initially atomized through the atomization plate 32, atomizing larger droplets into smaller particles, and then further heated and atomized through the electric heating plate 31, so that the anesthetic reaches the optimal atomization state, and finally enters the inner cavity of the oxygen mask 11 through the anesthetic gas source tube 17, providing effective anesthesia effect for the patient.

[0031] According to the content of the preferred technical solution described above, the workflow of the technical solution is explained: when using a breathing mask, first wear the oxygen mask 11 on the patient's face. At this time, the inflatable decompression lining strip 2 connected to the edge of the bottom end face of the oxygen mask 11 is in contact with the patient's face, and the hollow silicone strip 21 plays a buffering role. The flexible pressure sensor embedded in its bottom surface can monitor the extrusion pressure of the mask on the face. If the pressure is not appropriate, the inflation and deflation operation can be performed through the fixed inflation and deflation nozzle 22 that passes through the front opening of the top surface of the hollow silicone strip 21. The inflation and deflation nozzle 22 is connected to a medical air pump at one end away from the hollow silicone strip 21 to adjust the fit and comfort of the decompression lining strip 2 to the face.

[0032] During normal breathing, the silicone column 111 blocks the leaking tube 12 to prevent gas from leaking. When the carbon dioxide gas in the inner cavity of the oxygen mask 11 accumulates to a certain level and needs to escape to the outside, the silicone column 111 can be pulled out by the pulling strip 112 to allow the carbon dioxide gas to be discharged from the leaking port 15 through the leaking tube 12; the end-of-tidal monitoring port 16 opened on the front side of the top of the oxygen mask 11 is penetrated and fixed with the end-of-tidal monitoring tube 13, and the inner cavity of the end-of-tidal monitoring tube 13 is blocked with a silicone sealing block 110, and the top surface of the silicone sealing block 110 is fixedly connected to a plastic connecting strip 19, and the end of the plastic connecting strip 19 away from the silicone sealing block 110 is fixedly connected to the outer surface of the end-of-tidal monitoring tube 13. During body monitoring, the silicone sealing block 110 is taken out from the end-tidal monitoring tube 13 through the plastic connecting strip 19, and the top port of the end-tidal monitoring tube 13 is connected to the pipeline of the end-tidal monitoring instrument. The end-tidal gas enters the end-tidal monitoring instrument from the end-tidal monitoring port 16 through the end-tidal monitoring tube 13 for analysis; the top center of the oxygen mask 11 is connected to the anesthetic gas source tube 17, and the inner cavity of the anesthetic gas source tube 17 is blocked with a silicone plug 18. The top of the silicone plug 18 is fixedly connected to the gas source tube sealing plug 14 which is sleeved on the top port of the anesthetic gas source tube 17. The interior of the silicone plug 18 is provided with a cavity for its inward or outward deformation, and there is a space between the outer ring surface of the silicone plug 18 and the inner cavity side wall of the gas source tube sealing plug 14 for anesthetic The gap where the top port of the gas source tube 17 is inserted, a plastic strip 113 is fixedly connected to the outer surface side wall of the gas source tube sealing plug 14, and the end of the plastic strip 113 away from the gas source tube sealing plug 14 is fixedly connected to the top surface side wall of the oxygen inhalation mask 11. When anesthetic gas needs to be input, the gas source tube sealing plug 14 and the silicone plug 18 are removed from the top port of the anesthetic gas source tube 17 through the plastic strip 113. The top port of the anesthetic gas source tube 17 is connected to the delivery port of the anesthetic atomizer device through a pipeline. The anesthetic atomizer device includes an anesthetic atomizer 3, and the anesthetic atomizer 3 has an electric heating plate 31 fixed to the bottom of the inner cavity of the anesthetic gas source tube 17, and a heating plate 31 fixed to the top area of the inner cavity of the anesthetic gas source tube 17. The atomizing plate 32 has a plurality of through holes arranged in a ring array inside the electric heating plate 31, and a plurality of atomizing fine holes arranged in a ring array are opened inside the atomizing plate 32. After the anesthetic solution enters the anesthetic nebulizer 3, it first passes through the electric heating plate 31, and the electric heating plate 31 preheats the anesthetic solution. Then the anesthetic solution continues to rise, and the atomizing plate 32 atomizes the anesthetic solution droplets with larger particles. The atomized anesthetic agent passes through the through holes of the electric heating plate 31 and the anesthetic gas source pipe 17 into the oxygen mask 11 for inhalation by the patient; the bottom ends of the end-tidal monitoring tube 13 and the leakage tube 12 are both flush with the inner side wall curved surface of the oxygen mask 11 to reduce interference with the gas flow in the oxygen mask 11.
