Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anesthetic atomization for surgical anesthesia, in particular to an anesthetic atomization device for surgical anesthesia. BACKGROUND

[0002] Most existing anesthetic atomization devices adopt a continuous gas supply mode, which cannot automatically adjust with the patient's inhalation and exhalation, resulting in serious waste of anesthetics during exhalation, and the anesthetics remaining in the exhaled air are easy to diffuse and pollute the environment. In addition, unstable gas supply will also cause fluctuations in anesthetic concentration, affecting the stability of the anesthetic effect. Moreover, it is difficult to adapt to the changes in the patient's respiratory state before and after anesthesia when wearing a mask, and over-tightening can easily cause facial pressure injuries, while over-looseness can cause air leakage. Furthermore, it cannot dynamically respond to the respiratory intensity to adjust the fixing force, which not only affects the sealing performance but also reduces the patient's comfort, and increases the operation burden of medical staff. SUMMARY

In addition, unstable gas supply will also cause fluctuations in anesthetic concentration, affecting the stability of the anesthetic effect. Moreover, it is difficult to adapt to the changes in the patient's respiratory state before and after anesthesia when wearing a mask, and over-tightening can easily cause facial pressure injuries, while over-looseness can cause air leakage. Furthermore, it cannot dynamically respond to the respiratory intensity to adjust the fixing force, which not only affects the sealing performance but also reduces the patient's comfort, and increases the operation burden of medical staff.

One end of the anesthetic delivery pipe away from the first air suction pump is arranged in the inside of the connecting pipe. The outer surface of the oxygen tank is fixedly connected with a second air suction pump on one side. The inside of the second air suction pump is provided with an oxygen delivery pipe. One end of the oxygen delivery pipe away from the second air suction pump is arranged in the inside of the connecting pipe.

[0007] The breathing assembly includes a negative pressure valve, and the negative pressure valve is arranged inside the mixing tube. The end of the mixing tube away from the connecting tube is fixedly connected to the mask, and the end of the outlet pipe away from the mask is fixedly connected to the silicone inflatable sealing ring. An activated carbon filter layer is arranged inside the outlet pipe, and a one-way valve is arranged inside the outlet pipe.

[0008] Preferably, a fixed elastic band is fixedly connected to the outer surface of the mask, and the silicone inflatable sealing ring is a medical silicone inflatable sealing ring.

[0009] Preferably, the mixing tube, anesthetic delivery tube, oxygen delivery tube, air outlet tube, and air supply tube are all made of medical soft polyvinyl chloride material, and the spiral blades are made of medical soft polypropylene material.

[0010] Preferably, a pressure valve is provided inside the air supply pipe, a fixing plate is fixedly connected to the inner wall of the air supply pipe, and a spring is fixedly connected to one end of the outer surface of the fixing plate, and a plug is fixedly connected to the end of the spring away from the fixing plate.

[0011] Preferably, the plug is slidably embedded in the interior of the air supply pipe, the interior of the air supply pipe is connected to the anesthetic delivery pipe, the plug is slidably embedded in the interior of the anesthetic delivery pipe, and a pressure valve is provided inside the air supply pipe.

[0012] Preferably, a first air inlet pipe is fixedly connected to the top of the outer surface of the anesthesia box, and a pipe end cover is threadedly provided on the outer surface of the first air inlet pipe. A second air inlet pipe is fixedly connected to the top of the outer surface of the oxygen box, and a pipe end cover is threadedly provided on the outer surface of the second air inlet pipe.

[0013] Preferably, the interior of the mixing tube is communicated with the connecting tube, and the mixing tube is communicated with the interior of the mask.

[0014] Preferably, the air outlet pipe is connected to the interior of the mask, and the air outlet pipe is connected to the interior of the silicone inflatable sealing ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention puts the mask on the patient's face through a fixed elastic band fixed outside the mask. Before the patient is anesthetized, the patient is awake, breathes frequently and deeply, and exhales a lot of gas. The patient's exhaled gas is transported to the inside of the silicone inflatable sealing ring through the outlet pipe. The one-way valve in the outlet pipe ensures that the patient's exhaled gas is discharged smoothly, and gas will not accumulate in the mask to cause pressure increase. The gas is transported to the silicone inflatable sealing ring through the connected outlet pipe to inflate the silicone inflatable sealing ring. When the patient is awake, the silicone inflatable sealing ring is fully inflated, thereby fitting tightly to the patient's face, improving the sealing of the mask, and ensuring To ensure that subsequent anesthetic gas effectively enters the patient's respiratory tract, after anesthesia, the patient's breathing is shallow and slow, and the exhaled gas becomes less, and the pressure of the silicone inflatable sealing ring is naturally reduced, thereby avoiding the mask from being too tight and pressing on the facial skin, especially weak parts such as the bridge of the nose and cheekbones, reducing the risk of postoperative pressure sores and skin bruises. The tightness of the silicone inflatable sealing ring is automatically controlled by the patient's breathing status, and medical staff do not need to repeatedly adjust the tightness of the mask and headband. The mixing tube, anesthetic delivery tube, oxygen delivery tube, exhaust tube, and air supply tube are all made of medical polyvinyl chloride soft material, and the length can be adjusted according to actual needs.

[0017] 2. The anesthetic gas of the present invention contacts with oxygen in the connecting tube, and the mixed gas enters the interior of the mixing tube through the connecting tube. The inner wall of the mixing tube is fixed with a spiral blade, which rotates the two gases and forces the atomized anesthetic to be fully mixed with oxygen, thereby ensuring a uniform concentration of the anesthetic in the gas entering the mask, avoiding excessive local concentration that causes choking and respiratory depression, or excessively low concentration that causes insufficient anesthesia depth and patient movement, so as to make anesthesia induction and maintenance smoother.

[0018] 3. The present invention matches the patient's breathing to ensure that anesthetic gas is delivered on demand, avoiding drug waste caused by ineffective delivery during the exhalation period. During inhalation, only fresh anesthetic gas is inhaled, and no exhaled waste gas remains, thereby reducing waste gas residue. At the same time, through filtering by a one-way valve, anesthetic gas is prevented from directly leaking into the operating room environment, reducing the risks of liver and kidney damage, central nervous system stimulation, etc. caused by long-term exposure of medical staff. When the patient is anesthetized, his breathing gradually stabilizes, and the internal pressure of the silicone inflatable sealing ring gradually decreases, thereby triggering the opening of the pressure valve. The gas inside the silicone inflatable sealing ring is delivered to the inside of the air supply pipe through the pressure valve, and the gas pushes the plug to slide inside the air supply pipe. The air supply pipe is connected to the inside of the anesthetic delivery pipe. The anesthetic delivery pipe is blocked by the sliding of the plug, and the oxygen delivery pipe is used normally. The anesthetic delivery pipe is blocked by the plug, stopping the delivery of anesthetic, avoiding the patient's continued inhalation of anesthetic after losing consciousness, and reducing the risk of delayed postoperative recovery and respiratory depression.

[0030] See Figures 1 to 7 As shown, the mask 1 is put on the patient's face through a fixed elastic band fixed outside the mask 1. Before the patient is anesthetized, the patient is awake, breathes frequently and deeply, and exhales a lot of gas. The patient's exhaled gas is transported to the inside of the silicone inflatable sealing ring 5 through the outlet pipe 6. The one-way valve 602 in the outlet pipe 6 ensures that the patient's exhaled gas is discharged smoothly, and there is no gas accumulation in the mask 1 to cause pressure increase. The gas is transported to the silicone inflatable sealing ring 5 through the connected outlet pipe 6 to inflate the silicone inflatable sealing ring 5. When the patient is awake, the silicone inflatable sealing ring 5 is fully inflated, thereby fitting tightly to the patient's face, improving the sealing of the mask 1, and ensuring To ensure that subsequent anesthetic gas effectively enters the patient's respiratory tract, after the patient is anesthetized, the patient's breathing is shallow and slow, and the exhaled gas becomes less, and the pressure of the silicone inflatable sealing ring 5 is naturally reduced, thereby avoiding the mask 1 from pressing the facial skin too tightly, especially the weak parts such as the nose bridge and cheekbones, reducing the risk of postoperative pressure sores and skin bruises. The tightness of the silicone inflatable sealing ring 5 is automatically controlled by the patient's breathing status, and medical staff do not need to repeatedly adjust the tightness of the mask 1 and the headband.

One end is arranged inside the connecting pipe 401; the mixing pipe 4, the anesthetic delivery pipe 203, the oxygen delivery pipe 303, the air outlet pipe 6, and the air supply pipe 7 are all made of medical polyvinyl chloride soft material, and the spiral blade 403 is made of medical polypropylene soft material; the top of the outer surface of the anesthesia box 2 is fixedly connected to the first air inlet pipe 202, and the outer surface of the first air inlet pipe 202 is threadedly sleeved with a pipe end cap, and the top of the outer surface of the oxygen box 3 is fixedly connected to the second air inlet pipe 302, and the outer surface of the second air inlet pipe 302 is threadedly sleeved with a pipe end cap; the interior of the mixing pipe 4 is connected to the connecting pipe 401, and the mixing pipe 4 is connected to the interior of the mask 1;

[0032] See Figures 1 to 4 As shown, the medical staff adds the prepared anesthetic mist into the anesthesia box 2, and delivers oxygen to the oxygen box 3 through the second air inlet pipe 302. By turning on the first suction pump 201 and the second suction pump 301, the first suction pump 201 extracts anesthetic mist from the anesthesia box 2, and the anesthetic mist is delivered to the anesthetic delivery pipe 203 through the first suction pump 201. The second suction pump 301 extracts oxygen from the oxygen box 3, and the oxygen is delivered to the oxygen delivery pipe 303 through the second suction pump 301. The anesthetic gas and oxygen come into contact in the connecting pipe 401, and the mixed gas enters the interior of the mixing tube 4 through the connecting pipe 401. The inner wall of the mixing tube 4 is fixed with a spiral blade 403, and the spiral blade 403 causes the two gases to rotate, forcing the atomized anesthetic and oxygen to be fully mixed, ensuring that the anesthetic concentration in the gas entering the mask 1 is uniform, avoiding excessive local concentration causing choking and respiratory depression, or insufficient anesthesia depth caused by too low a concentration, and patient movement, so as to make anesthesia induction and maintenance more stable.

[0033] The breathing assembly includes a negative pressure valve 402, and the negative pressure valve 402 is arranged inside the mixing tube 4, the end of the mixing tube 4 away from the connecting tube 401 is fixedly connected to the mask 1, the end of the outlet pipe 6 away from the mask 1 is fixedly connected to the silicone inflatable sealing ring 5, the interior of the outlet pipe 6 is provided with an activated carbon filter layer 601, the interior of the outlet pipe 6 is provided with a one-way valve 602; the interior of the air supply pipe 7 is provided with a pressure valve 701, the inner wall of the air supply pipe 7 is fixedly connected to a fixing plate 702, and the fixing plate One end of the outer surface of 702 is fixedly connected to a spring 703, and the end of the spring 703 away from the fixed plate 702 is fixedly connected to a plug 704; the plug 704 is slidably embedded in the interior of the air supply pipe 7, the interior of the air supply pipe 7 is connected to the anesthetic delivery pipe 203, the plug 704 is slidably embedded in the interior of the anesthetic delivery pipe 203, and the interior of the air supply pipe 7 is provided with a pressure valve 701; the air outlet pipe 6 is connected to the interior of the mask 1, and the air outlet pipe 6 is connected to the interior of the silicone inflatable sealing ring 5;

[0034] See Figures 2 to 8 As shown, when the patient wears the mask 1 and inhales, the internal air pressure of the mask 1 decreases, so that the negative pressure valve 402 opens, thereby delivering the atomized anesthetic to the inside of the mask 1 to anesthetize the patient. When the patient exhales, the negative pressure valve 402 closes, and the exhaled gas is delivered to the silicone inflatable sealing ring 5 through the outlet pipe 6, and a one-way valve 602 is provided inside the outlet pipe 6. The unabsorbed anesthetic mist in the exhaled gas is filtered by the one-way valve 602, and the anesthetic gas is matched with the patient's breathing to ensure that the anesthetic gas is delivered on demand, avoiding drug waste caused by ineffective delivery during the exhalation period. When inhaling, only fresh anesthetic gas is inhaled, and no exhaled waste gas remains, thereby reducing waste gas residue. At the same time, the anesthetic gas is filtered by the one-way valve 602 to avoid direct leakage into the operating room environment, reducing medical care. Long-term exposure of personnel may lead to risks such as liver and kidney damage, central nervous system stimulation, etc. When the patient's breathing gradually stabilizes after anesthesia, the internal pressure of the silicone inflatable sealing ring 5 gradually decreases, thereby triggering the pressure valve 701 to open, and the gas inside the silicone inflatable sealing ring 5 is transported to the inside of the air supply pipe 7 through the pressure valve 701. The plug 704 is pushed by the gas to slide inside the air supply pipe 7, and the air supply pipe 7 is connected to the inside of the anesthetic delivery pipe 203.

The anesthetic delivery pipe 203 is blocked by the plug 704, and the delivery of the anesthetic is stopped, so as to avoid the patient from continuing to inhale the anesthetic after losing consciousness, thereby reducing the risk of delayed recovery and respiratory depression after surgery.

[0035] Working principle: The mask 1 is put on the patient's face through a fixed elastic band fixed outside the mask 1. Before the patient is anesthetized, the patient is awake, breathes frequently and deeply, and exhales a lot of gas. The patient's exhaled gas is transported to the inside of the silicone inflatable sealing ring 5 through the outlet pipe 6. The one-way valve 602 in the outlet pipe 6 ensures that the patient's exhaled gas is discharged smoothly, and there will be no gas accumulation in the mask 1 to cause pressure increase. The gas is transported to the silicone inflatable sealing ring 5 through the connected outlet pipe 6 to inflate the silicone inflatable sealing ring 5. When the patient is awake, the silicone inflatable sealing ring 5 is fully inflated, so that it fits the patient's face tightly. The mixing tube 4, anesthetic delivery tube 203, oxygen delivery tube 303, outlet pipe 6, and air supply tube 7 are all made of medical polyvinyl chloride soft material, and the length can be adjusted according to actual needs;

[0036] The medical staff adds the prepared anesthetic mist into the anesthesia box 2, and delivers oxygen to the oxygen box 3 through the second air inlet pipe 302. By turning on the first suction pump 201 and the second suction pump 301, the first suction pump 201 extracts anesthetic mist from the anesthesia box 2, and the anesthetic mist is delivered to the anesthetic delivery pipe 203 through the first suction pump 201. The second suction pump 301 extracts oxygen from the oxygen box 3, and the oxygen is delivered to the oxygen delivery pipe 303 through the second suction pump 301. The anesthetic gas and oxygen come into contact in the connecting pipe 401, and the mixed gas enters the interior of the mixing tube 4 through the connecting pipe 401. The inner wall of the mixing tube 4 is fixed with a spiral blade 403, and the two gases are rotated by the spiral blade 403, forcing the atomized anesthetic and oxygen to be fully mixed, thereby ensuring a uniform anesthetic concentration in the gas entering the mask 1;

[0037] When the patient wears the mask 1 and inhales, the internal air pressure of the mask 1 decreases, so that the negative pressure valve 402 opens, thereby delivering the atomized anesthetic to the inside of the mask 1 to anesthetize the patient. When the patient exhales, the negative pressure valve 402 closes, and the exhaled gas is delivered to the silicone inflatable sealing ring 5 through the outlet pipe 6, and a one-way valve 602 is provided inside the outlet pipe 6. The unabsorbed anesthetic mist in the exhaled gas is filtered by the one-way valve 602, and the anesthetic gas is matched with the patient's breathing to ensure that the anesthetic gas is delivered on demand, avoiding the waste of medicine caused by ineffective delivery during the exhalation period. When inhaling, only fresh anesthetic gas is inhaled, and no exhaled waste gas remains, thereby reducing waste gas residue. At the same time, the anesthetic gas is filtered by the one-way valve 602 to avoid It leaks directly into the operating room environment, reducing the risks of liver and kidney damage, central nervous system stimulation, etc. caused by long-term exposure of medical staff. When the patient's breathing gradually stabilizes after anesthesia, the internal pressure of the silicone inflatable sealing ring 5 gradually decreases, thereby triggering the pressure valve 701 to open, and the gas inside the silicone inflatable sealing ring 5 is transported to the inside of the air supply pipe 7 through the pressure valve 701. The plug 704 is pushed by the gas to slide inside the air supply pipe 7, and the air supply pipe 7 is connected to the inside of the anesthetic delivery pipe 203. The anesthetic delivery pipe 203 is blocked by the sliding of the plug 704, and the oxygen delivery pipe 303 is used normally. The anesthetic delivery pipe 203 is blocked by the plug 704 to stop the delivery of anesthetic.
