Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anesthesia mask and an anesthesia method. Background Art

[0002] The anesthesia mask is a medical emergency device used in conjunction with an anesthesia machine and a ventilator. It delivers anesthetic gas and is used when the patient inhales anesthetic gas. It is mainly used for anesthesia, respiratory resuscitation and surgery. It can relieve the pain of patients, especially infants and young children, during surgery and allow the operation to proceed smoothly. At present, anesthesia masks are used in clinical practice for general anesthesia induction and emergency resuscitation.

[0003] During use, the anesthetic needs to be calculated according to the patient's body shape to avoid excessive or insufficient use of anesthetic, which will fail to effectively anesthetize the patient and increase the risk of the operation. Most of the existing anesthesia masks maintain a close seal with the patient's face through the flexible deformation of the air bag or rubber ring to ensure the sealing of the anesthesia mask. The structure is simple, but there is no seal detection function. It is impossible to determine whether the mask will leak during use, which may result in the dose of anesthetic entering the patient's body being less than the expected value, causing the patient to be awake during the operation, reducing the analgesic effect of the patient, increasing the patient's psychological pressure, and causing a stress response, thereby increasing the risk of the operation. Therefore, the present application provides an anesthesia mask to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an anesthesia mask to solve the problem that the existing anesthesia mask has no sealing detection function, and it is impossible to determine whether the mask will leak when in use, thereby causing the anesthetic dose entering the patient's body to be less than the expected value, causing the patient to be awake during the operation, reducing the patient's analgesic effect, increasing the patient's psychological pressure, and generating a stress response, thereby increasing the risk of the operation.

The air tightness of the mask body is judged by the duration of deformation of the detection component, the blocking component is limited by the first limiting component before the air tightness detection, the blocking component is limited by the second limiting component before the air tightness detection, and the detection component after the detection is blocked by the blocking component to prevent anesthetic gas from entering the detection component. During anesthesia, the anesthesia machine pumps anesthetic into the mask body through the first ventilation tube, and the anesthetic in the mask body is prevented from flowing back into the first ventilation tube through the one-way conductive component in the first ventilation tube. The anesthetic in the mask body is prevented from flowing back into the first airbag through the one-way conductive component in the second ventilation tube. At the same time, the anesthetic gas enters the first airbag through the first ventilation tube and the third ventilation tube. When the medical staff squeezes the first airbag through the first ventilation tube, the second ventilation tube and the one-way conductive component in the third ventilation tube, the residual anesthetic in the first ventilation tube is pumped into the mask body through the third ventilation tube and the second ventilation tube.

[0007] Preferably, the one-way conducting component includes a limit plate fixedly installed in the first ventilation pipe, the second ventilation pipe and the third ventilation pipe, respectively. A plurality of first limit rods are fixedly installed in the first ventilation pipe, the second ventilation pipe and the third ventilation pipe in a circular array, and the sphere is placed between the limit plate and the first limit rod.

[0008] Preferably, an air nozzle is fixedly mounted on one side of the mask body, and the mask body penetrates and extends into the mask body.

[0009] Preferably, the detection component includes a limit frame fixedly installed on one side of the mask body, a second air bag is fixedly sleeved on the air nozzle, the second air bag is located in the limit frame, scales are set around the limit frame, and the limit frame is made of transparent material.

[0011] Preferably, the first limiting component includes a third limiting ring fixedly mounted on one side of the limiting frame, a first retreat groove is provided on the sliding rod, a first cavity communicating with the first retreat groove is provided in the sliding rod, a sliding block is slidably sleeved in the first cavity, a second limiting rod is fixedly mounted on the top of the sliding block, the second limiting rod is clamped with the third limiting ring, a second spring sleeved outside the second limiting rod is fixedly connected to the top of the sliding block, and an end of the second spring away from the sliding block contacts with the top inner wall of the first cavity.

[0012] Preferably, the second limiting component includes a second limiting ring fixedly mounted on the other side of the limiting frame, a plurality of second retreat grooves are symmetrically formed on the outer side of the slide rod about the axis of the slide rod, and a clamping block is fixedly mounted on one side of the second retreat groove.

[0013] Preferably, the first spring is located outside the second limiting ring, and the second limiting rod is an L-shaped rod.

[0014] Preferably, the card block is an L-shaped card block, and a rounded corner is provided at the bending portion of the card block.

[0015] An anesthesia method, using the above anesthesia mask, includes the following steps:

[0016] S1: Before anesthesia, press the anesthesia mask on the patient's face and ask the patient to hold his breath, squeeze the first airbag, and pump the gas in the first airbag into the second airbag through the second ventilation tube and the one-way conductive component inside the first airbag through the air nozzle to expand the second airbag. The second airbag expands and squeezes the slide plate, and observe whether the slide plate moves. The air tightness is judged by the preset range value. When the slide plate moves within the preset range, it means that the air tightness of the anesthesia mask is good. If the movement of the slide plate exceeds the preset range, the air tightness of the anesthesia mask is unqualified, and a new anesthesia mask needs to be replaced for re-testing until the air tightness meets the standard and anesthesia is started;

[0017] S2: During the airtightness inspection, the slide plate is squeezed and moved by the second airbag, and the first limiting component releases the limit on the slide bar;

[0018] S3: After the airtightness check is completed, the patient breathes spontaneously, and the slide plate moves due to the elastic force of the first spring, and the slide plate moves to squeeze the second airbag until the gas in the second airbag is completely exhausted, at which time the second limiting component limits the slide bar;

[0019] S4: During anesthesia, the connecting tube of the anesthetic is connected to the first ventilation tube, and the anesthetic is pumped into the mask body through the first ventilation tube to anesthetize the patient;

[0020] S5: When the anesthesia machine no longer pumps anesthetic into the mask body through the first ventilation tube, the anesthetic entering the first airbag and the anesthetic remaining in the first ventilation tube enter the mask body by continuously squeezing and stretching the first airbag, so that the anesthetic is fully utilized.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above scheme, a slide plate is set to observe whether the slide plate moves, and the air tightness is judged by the preset range value. When the slide plate moves within the preset range, it means that the air tightness of the anesthesia mask is good. If the movement of the slide plate exceeds the preset range, the air tightness of the anesthesia mask is unqualified, and a new anesthesia mask needs to be replaced and tested again until the air tightness of the newly replaced anesthesia mask meets the standard and anesthesia is started. Through the upper structural design, it can be determined whether the anesthesia mask will leak during use, so that the anesthetic dose entering the patient's body is the same as the expected value, avoiding the patient from being awake during the operation, ensuring the anesthetic and analgesic effect on the patient, reducing the patient's psychological pressure, and avoiding the patient's stress response, thereby improving the safety of the operation.

[0023] By setting a card block, after completing the airtightness check, the card block moves to the inside of the limit frame, resets under the action of its own elastic force, and contacts the inner wall of one side of the limit frame and the inner circle of the second limit ring, completing the limitation of the slide bar, and at the same time squeezing the second airbag so that the inner wall of the second airbag fits with one end of the air nozzle to prevent the second airbag from expanding. The upper structural design makes it possible for the second airbag to be unable to expand again after completing the airtightness test of the device, thereby preventing anesthetic from entering the second airbag during anesthesia and causing waste of anesthetic, thereby ensuring the steady progress of the anesthesia process and the safety of the operation.

[0024] By setting up the first ventilation tube, during anesthesia, the connecting tube of the anesthetic is connected to the first ventilation tube, and the anesthetic is pumped into the mask body through the first ventilation tube to anesthetize the patient. When the anesthetic in the mask body flows back, the ball is squeezed and the ball conflicts with the limit plate, so that the anesthetic in the mask body cannot flow back, thereby ensuring that the anesthetic in the mask body is fully utilized, ensuring the anesthesia effect of the patient, and improving the safety of the operation.

[0025] By setting up the first ventilation tube, the second ventilation tube, and the third ventilation tube, medical staff continuously squeeze and expand the first airbag outward through the first limiting ring to allow the anesthetic entering the first airbag and the anesthetic remaining in the first ventilation tube to enter the mask body, so that the anesthetic is fully utilized, saving medical costs, further ensuring the effective anesthesia of the patient, and improving the safety of the operation.

[0043] like Figure 1-Figure 4As shown, an embodiment of the present invention provides an anesthesia mask, including a mask body 1, a first air bag 2 is fixedly installed on the top of the mask body 1, the first air bag 2 is filled with air, a first ventilation tube 4 that penetrates and extends into the mask body 1 is fixedly sleeved on the top of the first air bag 2, and two first limiting rings 3 are fixedly installed on both sides of the first ventilation tube 4 symmetrically about the center of the first ventilation tube 4. When using the device, medical staff put their fingers through the two first limiting rings 3, and the two first limiting rings 3 improve the medical staff's grip on the first air bag 2, so as to facilitate medical staff When personnel squeeze and stretch the first airbag 2, a sealing ring 11 is fixedly installed at the bottom of the mask body 1, and a detection component, a blocking component, a first limit component and a second limit component connected to each other are installed on the mask body 1. A first ventilation pipe 4 and a second ventilation pipe 5 are fixedly installed on the top of the mask body 1, and a third ventilation pipe 6 is fixedly installed on the first ventilation pipe 4. The first ventilation pipe 4 and the second ventilation pipe 5 both penetrate and extend into the mask body 1, and the third ventilation pipe 6 penetrates and extends into the first ventilation pipe 4. The first ventilation pipe 4, the second ventilation pipe 5, and the third ventilation pipe 6 are all fixed. A one-way conductive component is installed; when detecting the air tightness of the mask body 1, the first airbag 2 is squeezed to allow the gas in the first airbag 2 to enter the detection component through another one-way conductive component, and the air tightness of the mask body 1 is judged by the duration of the deformation of the detection component. The blocking component before the air tightness detection is limited by the first limiting component, and the blocking component before the air tightness detection is limited by the second limiting component. The detection component after the detection is blocked by the blocking component to prevent anesthetic gas from entering the detection component. During anesthesia, the anesthesia machine pumps anesthetic into the mask body 1 through the first ventilation pipe 4. The anesthetic agent in the mask body 1 is prevented from flowing back into the first ventilation tube 4 through the one-way conductive component in the first ventilation tube 4, and the anesthetic agent in the mask body 1 is prevented from flowing back into the first airbag 2 through the one-way conductive component in the second ventilation tube 5. At the same time, the anesthetic gas enters the first airbag 2 through the first ventilation tube 4 and the third ventilation tube 6. When the medical staff squeezes the first airbag 2 through the one-way conductive components in the first ventilation tube 4, the second ventilation tube 5 and the third ventilation tube 6, the residual anesthetic agent in the first ventilation tube 4 is pumped into the mask body 1 through the third ventilation tube 6 and the second ventilation tube 5.

[0044] like Figure 1-Figure 4As shown, in the present embodiment, the one-way conducting component comprises a limiting plate 7 fixedly mounted in the first ventilation tube 4, the second ventilation tube 5 and the third ventilation tube 6 respectively, and a plurality of first limiting rods 8 are fixedly mounted in the first ventilation tube 4, the second ventilation tube 5 and the third ventilation tube 6 in a circular array, and a sphere 9 is placed between the limiting plate 7 and the first limiting rod 8; an air nozzle 10 is fixedly mounted on one side of the mask body 1, and the mask body 1 penetrates and extends into the mask body 1; the detection component comprises a limiting frame 13 fixedly mounted on one side of the mask body 1, a second air bag 12 is fixedly sleeved on the air nozzle 10, and the second air bag 12 is located in the limiting frame 13, and scales are arranged around the limiting frame 13, and the limiting frame 13 is made of transparent material, and the surface of the slide plate 16 is coated with red paint, so that the medical staff can observe the slide plate 16 when detecting the air tightness of the anesthesia mask.

[0045] Before anesthesia, the device is pressed on the patient's face and the patient is asked to hold his breath, and the first airbag 2 is squeezed. The gas in the first airbag 2 passes through the second ventilation tube 5 and the limiting plate 7 and the first limiting rod 8 in the second ventilation tube 5 through the mask body 1 and the air nozzle 10 and is pumped into the second airbag 12, so that the second airbag 12 expands. The second airbag 12 expands and squeezes the slide plate 16, and observes whether the slide plate 16 moves. The air tightness is judged by the preset range value. When the slide plate 16 moves within the preset range, it means that the air tightness of the anesthesia mask is good. If the movement of the slide plate 16 exceeds the preset range, the air tightness of the anesthesia mask is unqualified, and a new anesthesia mask needs to be replaced for re-testing until the air tightness of the newly replaced anesthesia mask meets the standard before anesthesia is started. Through the upper structural design, it can be determined whether the anesthesia mask will leak during use, so that the anesthetic dose entering the patient's body is the same as the expected value, avoiding the patient from being awake during the operation, ensuring the anesthesia and analgesia effect on the patient, reducing the patient's psychological pressure, and avoiding the patient from having a stress response, thereby improving the safety of the operation.

[0046] like Figure 1 , Figure 5-Figure 7As shown, in the present embodiment, the blocking component comprises a slide plate 16 slidably sleeved with the limit frame 13, a slide bar 17 is fixedly mounted on one side of the slide plate 16, the slide bar 17 penetrates and extends to the outside of the limit frame 13, a first spring 18 sleeved on the slide bar 17 is fixedly mounted on one side of the slide plate 16, one end of the first spring 18 abuts against an inner wall of one side of the limit frame 13; the first limit component comprises a third limit ring 15 fixedly mounted on one side of the limit frame 13, a first retreat groove 23 is provided on the slide bar 17, a first cavity 19 communicating with the first retreat groove 23 is provided in the slide bar 17, a slide block 20 is slidably sleeved in the first cavity 19, a second limit rod 21 is fixedly mounted on the top of the slide block 20, the second limit rod 21 is clamped with the third limit ring 15, a second spring 22 sleeved outside the second limit rod 21 is fixedly connected to the top of the slide block 20, and an end of the second spring 22 away from the slide block 20 abuts against the top inner wall of the first cavity 19.

[0047] During the airtightness inspection, the inflated second airbag 12 squeezes the slide plate 16 to move the slide plate 16, and the slide plate 16 drives the second limit rod 21 to move through the second spring 22, thereby canceling the engagement between the second limit rod 21 and the third limit ring 15. Under the elastic force of the second spring 22, the slider 20 moves along the inner wall of the first cavity 19, and drives the second limit rod 21 to engage with the first retreat groove 23 to release the limitation on the slide rod 17.

[0048] like Figure 5 and Figure 6 As shown, in this embodiment, the second limiting component includes a second limiting ring 14 fixedly installed on the other side of the limiting frame 13, and a plurality of second retreat grooves 25 are symmetrically provided on the outer side of the slide rod 17 about the axis of the slide rod 17, and a clamping block 24 is fixedly installed on one side of the second retreat groove 25.

[0049] After the airtightness check is completed, the patient breathes spontaneously, and the sliding bar 17 without limit drives the slide plate 16 to move along the inner wall of the limit frame 13 under the elastic force of the first spring 18. The moving slide plate 16 squeezes the second airbag 12 and drives the block 24 to move. During the movement of the block 24, it is squeezed and deformed by the third limit ring 15 and moves into the second retreat groove 25. When the gas in the second airbag 12 is completely exhausted, the block 24 moves to the inside of the limit frame 13 and resets under the action of its own elastic force. , and the inner wall of one side of the limit frame 13 and the inner circle of the second limit ring 14 are in conflict to complete the limitation of the slide bar 17, and at the same time, the second airbag 12 is squeezed to make the inner wall of the second airbag 12 fit with one end of the air nozzle 10 to prevent the second airbag 12 from expanding. Through the upper structural design, after the airtightness test of the device is completed, the second airbag 12 cannot be inflated again, thereby preventing the anesthetic from entering the second airbag 12 during the anesthesia process, causing a waste of anesthetics, ensuring the steady progress of the anesthesia process, and ensuring the safety of the operation.

[0050] During anesthesia, the connecting tube of the anesthetic is connected to the first ventilation tube 4, and the anesthetic is pumped into the mask body 1 through the first ventilation tube 4 to anesthetize the patient. When the anesthetic in the mask body 1 flows back, the ball 9 is squeezed, and the ball 9 conflicts with the limiting plate 7, so that the anesthetic in the mask body 1 cannot flow back, thereby ensuring that the anesthetic in the mask body 1 is fully utilized, ensuring the anesthesia effect of the patient, and improving the safety of the operation.

[0051] At the same time, the anesthetic will also enter the first airbag 2 through the third ventilation tube 6. The medical staff holds the first airbag 2 to prevent the first airbag 2 from continuing to expand. When the anesthesia machine no longer pumps anesthetic into the mask body 1 through the first ventilation tube 4, that is, the anesthesia is about to end, the medical staff continuously squeezes and expands the first airbag 2 outward through the first limiting ring 3 to make the anesthetic entering the first airbag 2 and the anesthetic remaining in the first ventilation tube 4 enter the mask body 1, so that the anesthetic is fully utilized; the specific process is: when the first airbag 2 is squeezed, the anesthetic in the first airbag 2 enters the mask body 1 through the second ventilation tube 5, and the air pressure in the mask body 1 affects the spheres 9 in the first ventilation tube 4 and the second ventilation tube 5. They all conflict with the limiting plate 7 to prevent the anesthetic in the mask body 1 from flowing back into the first ventilation tube 4 and the first airbag 2. Affected by the air pressure in the first airbag 2, the sphere 9 in the third ventilation tube 6 conflicts with the limiting plate 7 to prevent the anesthetic from flowing back into the first ventilation tube 4. When the medical staff expands the first airbag 2 outward through the first limiting ring 3, under the action of the negative pressure in the first airbag 2, the residual anesthetic in the first ventilation tube 4 enters the first airbag 2 through the third ventilation tube 6. The anesthetic in the first airbag 2 enters the mask body 1 by squeezing the first airbag 2 again. The above operation can be repeated to fully utilize the residual anesthetic, thereby saving medical costs, further ensuring the effective anesthesia of the patient, and improving the safety of the operation.

[0052] like Figure 5 and Figure 6 As shown, in the present embodiment, the block 24 is an L-shaped block, and a rounded corner is provided at the bending part of the block 24 to facilitate guiding the bending of the block 24, thereby preventing the block 24 from being engaged with the third limiting ring 15 during movement, and ensuring the normal use of the block 24.

[0053] like Figure 5-Figure 7 As shown, in this embodiment, the first spring 18 is located outside the second limiting ring 14, and the second limiting rod 21 is an L-shaped rod, so that the block 24 directly contacts the second limiting ring 14 after entering the limiting frame 13, thereby increasing the limiting stability of the block 24.

[0054] The technical solution provided by the present invention is to set a slide plate, press the device on the patient's face and ask the patient to hold his breath, squeeze the first airbag, and the gas in the first airbag is pumped into the second airbag through the second ventilation tube and the limiting plate in the second ventilation tube, the first limiting rod, the mask body, and the air nozzle to expand the second airbag. The second airbag expands and squeezes the slide plate, and observe whether the slide plate moves. The air tightness is judged by the preset range value. When the slide plate moves within the preset range, it means that the air tightness of the anesthesia mask is good. If the movement of the slide plate exceeds the preset range, the air tightness of the anesthesia mask is unqualified, and a new anesthesia mask needs to be replaced for re-testing until the air tightness of the newly replaced anesthesia mask meets the standard before anesthesia is started. Through the upper structural design, it can be determined whether the anesthesia mask will leak during use, so that the anesthetic dose entering the patient's body is the same as the expected value, avoiding the patient from being awake during the operation, ensuring the anesthetic and analgesic effect on the patient, reducing the patient's psychological pressure, and avoiding the patient from having a stress response, thereby improving the safety of the operation.

[0055] By setting a second limit rod, the inflated second airbag squeezes the slide plate to move the slide plate, and the slide plate drives the second limit rod to move through the second spring, thereby canceling the clamping connection between the second limit rod and the third limit ring. Under the elastic force of the second spring, the slider moves along the inner wall of the first cavity and drives the second limit rod to clamp with the first retreat groove to release the limit on the slide rod.

[0056] By setting the card block, after the airtight check is completed, the patient breathes spontaneously, and the sliding bar that has lost its limit drives the sliding plate to move along the inner wall of the limit frame under the elastic force of the first spring. The moving sliding plate squeezes the second airbag and drives the card block to move at the same time. During the movement of the card block, it is squeezed and deformed by the third limit ring and moves into the second retreat groove. When the gas in the second airbag is completely exhausted, the card block moves to the inside of the limit frame and resets under the action of its own elastic force, and contacts the inner wall of one side of the limit frame and the inner circle of the second limit ring to complete the limiting of the sliding bar and squeeze the second airbag at the same time, so that the inner wall of the second airbag fits with one end of the air nozzle to prevent the second airbag from expanding. Through the upper structural design, the second airbag cannot be inflated again after the airtight test is completed, so as to avoid the anesthetic from entering the second airbag during the anesthesia process and causing the waste of anesthetic, thereby ensuring the steady progress of the anesthesia process and the safety of the operation.

[0057] By setting up the first ventilation tube, during anesthesia, the connecting tube of the anesthetic is connected to the first ventilation tube, and the anesthetic is pumped into the mask body through the first ventilation tube to anesthetize the patient. When the anesthetic in the mask body flows back, the ball is squeezed and the ball conflicts with the limit plate, so that the anesthetic in the mask body cannot flow back, thereby ensuring that the anesthetic in the mask body is fully utilized, ensuring the anesthesia effect of the patient, and improving the safety of the operation.

[0058] By providing the first ventilation tube, the second ventilation tube, and the third ventilation tube, the anesthetic agent will also enter the first airbag through the third ventilation tube. By the medical staff holding the first airbag, the first airbag is prevented from continuing to expand. When the anesthesia machine no longer pumps anesthetic agent into the mask body through the first ventilation tube, that is, when the anesthesia is about to end, the medical staff continuously squeezes and expands the first airbag outwards through the first limiting ring so that the anesthetic agent entering the first airbag and the anesthetic agent remaining in the first ventilation tube enter the mask body, so that the anesthetic agent is fully utilized. The specific process is: when the first airbag is squeezed, the anesthetic agent in the first airbag enters the mask body through the second ventilation tube. The air pressure in the mask body affects the air pressure in the first ventilation tube and The balls in the second ventilation tube all collide with the limiting plate to prevent the anesthetic in the mask body from flowing back into the first ventilation tube and the first airbag. Affected by the air pressure in the first airbag, the balls in the third ventilation tube collide with the limiting plate to prevent the anesthetic from flowing back into the first ventilation tube. When the medical staff expands the first airbag outward through the first limiting ring, the negative pressure in the first airbag allows the residual anesthetic in the first ventilation tube to enter the first airbag through the third ventilation tube. The anesthetic in the first airbag is squeezed again to enter the mask body. The above operation can be repeated to fully utilize the residual anesthetic, saving medical costs, further ensuring effective anesthesia for patients, and improving the safety of surgery.
