Description

Technical Field

[0001] The invention belongs to the technical field of anesthesia devices, and in particular relates to an anesthesia device with adjustable concentration. Background Art

[0002] With the advancement of medical technology, many diseases that were difficult to solve in the past can now be easily cured through surgery. However, surgery usually involves cutting and suturing of the body. These processes can cause severe pain and trigger stress responses in patients, such as increased blood pressure and increased heart rate. These stress responses may increase surgical risks and affect surgical outcomes. Anesthetics can block nerve conduction, making patients feel no pain during surgery. The use of anesthetics not only helps reduce patients' pain and stress responses, but also improves surgical quality and safety.

[0003] Precise control of anesthetic concentration is crucial to the surgical process. Too high a concentration may lead to serious complications such as respiratory depression and slow heartbeat, while too low a concentration may cause the patient to feel pain or lose consciousness during surgery, thus affecting the smooth progress of the surgery. Doctors can accurately adjust the concentration of anesthetic drugs according to surgical needs and the patient's physical condition, thereby greatly improving the safety of the surgery.

[0004] However, factors such as the patient's age, weight, and health status will affect the metabolism and effect of anesthetic drugs, and traditional anesthesia devices are often difficult to accurately adjust according to individual differences in patients. Anesthesia devices with adjustable concentrations can set personalized anesthesia plans based on the patient's specific conditions, thereby improving the accuracy of anesthesia and the patient's comfort. Anesthesia devices with adjustable concentrations are usually equipped with advanced monitoring systems and control algorithms that can monitor the patient's vital signs and anesthesia depth in real time and automatically adjust as needed, which not only improves the accuracy and efficiency of anesthesia, but also reduces the workload of medical staff.

[0005] After measuring the volume of different reagents, the existing concentration-adjustable anesthesia devices will pass through the connecting tube before stirring. The connecting tube between the reagent storage tank and the mixing device is prone to leaving residual liquid, affecting the accuracy of the final concentration of the anesthetic, resulting in an error between the anesthesia effect and the expected effect. Summary of the invention

[0006] The main purpose of the present invention is to provide an anesthesia device with adjustable concentration, which solves the problem that after the device measures the volume of different reagents, the volume will pass through various connecting tubes before stirring and mixing, and the connecting tubes between the reagent storage tank and the mixing device are prone to leave residual liquid, affecting the accuracy of the final concentration of the anesthetic, causing the anesthetic effect to be different from the expected effect.

DETAILED DESCRIPTION

[0019] In order to improve the problem that after the anesthesia device in the related art measures the volume of different reagents, the volume will pass through various connecting tubes before stirring and mixing, and the connecting tubes between the reagent storage tank and the mixing device are prone to leave residual liquid, affecting the final concentration accuracy of the anesthetic, causing the anesthetic effect to be different from the expected effect. The embodiment of the present application provides the following solution.

[0020] Please also read Figure 1-Figure 5, including a frame 1, a mixing mechanism 4, a switch 14, a storage tank 3, a first one-way valve 8 and a reagent tank 2, the mixing mechanism 4 includes a stirring tank 43 and a driving assembly 41, the stirring tank 43 is arranged on the frame 1, and the driving assembly 41 is arranged on the stirring tank 43; a connecting through hole 42 is opened at the bottom of the stirring tank 43; the switch 14 is movably arranged on the bottom of the stirring tank 43, and is used to open or close the connecting through hole 42; the storage tank 3 includes a tank body 31 and an exchange membrane 32, and the tank body 31 is rotatably arranged in the stirring tank 43 The driving assembly 41 is used to drive the tank body 31 to rotate; an exchange through hole 33 is opened on the side wall of the tank body 31, and the exchange membrane 32 is arranged in the exchange through hole 33; an injection through hole 34 is opened at the bottom of the tank body 31, and a first one-way valve 8 is arranged at the injection through hole 34; the reagent tank 2 is located below the stirring tank 43, and the output end of the reagent tank 2 can be connected to the first one-way valve 8 through the connecting through hole 42 and the on-off piece 14, which is used to inject reagent into the tank body 31 when the output end of the reagent tank 2 is connected to the first one-way valve 8.

[0021] It can be understood that the stirring tank 43 can be arranged on the frame 1 in a movable connection manner, so as to facilitate subsequent removal and maintenance; the exchange membrane 32 can be opened under a certain pressure difference, so as to complete the mutual fusion of the reagent in the tank body 31 and the reagent in the stirring tank 43; As can be seen from the above, the reagent in the reagent tank 2 is injected into the storage tank 3. During this process, due to the presence of the exchange membrane 32, the reagent will not flow out through the exchange through hole 33. After the reagent injection is completed, the reagent tank 2 is removed, and the on-off piece 14 is adjusted to close the connecting through hole 42. Due to the effect of the first one-way valve 8, during the process of adjusting the on-off piece 14, the reagent in the storage tank 3 will not flow out, and the reagent is still inside the storage tank 3. The reagent tank 2 is directly connected to the storage tank 3, and there is no problem of residual liquid medicine being easily left at the connection; after the on-off piece 14 completely closes the connecting through hole 42, the driving component 41 drives the storage tank 3 to rotate. Under the pressure generated by the centrifugal force, the reagent in the tank body 31 flows out from the exchange through hole 33 through the exchange membrane 32, and the reagent gathers in the stirring tank 43. The storage tank 3 also acts as a stirring member to mix and evenly mix the reagent in the stirring tank 43.

[0022] Optionally, in some embodiments, please refer to Figure 5 A receiving space 6 is provided inside the bottom of the mixing tank 43 , and the connecting through hole 42 is connected to the receiving space 6 ; the switch 14 is movably arranged in the receiving space 6 and connected to the power output end of the driving component 41 .

[0023] It can be understood that the switch piece 14 rotates in the accommodating space 6 under the action of the driving assembly 41 , and the upper end surface of the switch piece 14 fits with the upper end surface inside the accommodating space 6 .

[0024] With such arrangement, the design of the first one-way valve 8 is sufficient to ensure that after the reagent injection is completed, the reagent in the storage tank 3 will not flow out when the reagent tank 2 is pulled out. However, after the reagent tank 2 is pulled out, the connecting hole 42 at the bottom of the stirring tank 43 is still connected to the external environment. After the driving component 41 drives the storage tank 3 to rotate, the reagent will flow out through the connecting hole 42, and the on-off piece 14 can block the connecting hole 42, thereby ensuring the smooth progress of the mixing process.

[0025] Optionally, in some embodiments, please refer to Figure 2 as well as Figure 5 A connecting pipe 5 is provided above the reagent tank 2, and the connecting pipe 5 is connected to the first one-way valve 8 through the connecting through hole 42. An electric push rod 9 and a sealing ring 10 are provided in the reagent tank 2. The outer wall of the sealing ring 10 abuts against the inner wall of the reagent tank 2, and the end of the sealing ring 10 away from the connecting pipe 5 abuts against the electric push rod 9, and the output end of the electric push rod 9 is slidably connected to the inner wall of the reagent tank 2.

[0026] It can be understood that the connecting pipe 5 can be arranged above the reagent tank 2 in a movable connection manner, and the connecting pipe 5 can be a hose; With such arrangement, the connecting pipe 5 lengthens the connection distance between the reagent tank 2 and the storage tank 3, the connecting pipe 163 of the reagent tank 2 is aligned with the outside of the first one-way valve 8 and is clamped, the output end of the electric push rod 9 starts to move, and the reagent in the reagent tank 2 is injected into the storage tank 3, the sealing ring 10 prevents the reagent in the reagent tank 2 from entering the electric push rod 9 to corrode the equipment, and after the electric push rod 9 stops working, the first one-way valve 8 is closed. When the connecting pipe 5 is a hose, the on-off piece 14 can be directly operated to rotate, and the connecting pipe 5 is automatically disengaged from the first one-way valve 8 through the squeezing action of the on-off piece 14.

[0027] Optionally, in some embodiments, please refer to Figure 2 , Figure 3 as well as Figure 5The driving assembly 41 includes a protective cover 411, a first rotating shaft 412, a second rotating shaft 413, a first rotating motor 414 and a second rotating motor 415. The protective cover 411 is arranged above the stirring tank 43 and forms a protective chamber 416. The first rotating motor 414 and the second rotating motor 415 are arranged in the protective chamber 416. The first rotating shaft 412 is arranged inside the stirring tank 43, and the first rotating shaft 412 is rotatably connected to the output end of the first rotating motor 414. The on-off member 14 is fixedly connected to the end of the first rotating shaft 412 away from the first rotating motor 414. A groove is provided at the end of the first rotating shaft 412 close to the on-off member 14, and a plurality of through holes are provided on the outer wall of the groove. A second one-way valve 15 is provided at the groove. A gear 417 is fixedly connected to the output end of the second rotating motor 415. The second rotating shaft 413 is sleeved on the first rotating shaft 412. The end of the second rotating shaft 413 close to the protective cover 411 is in the shape of a gear 417. The second rotating motor 415 is transmission-connected to the second rotating shaft 413.

[0028] It can be understood that the protective cover 411 can be arranged above the stirring tank 43 in a movable connection manner, and a vent hole is opened on the protective cover 411; the first rotating motor 414 is fixedly connected to the protective cover 411, and the second rotating motor 415 is fixedly connected above the stirring tank 43; a small part of the first rotating shaft 412 and the second rotating shaft 413 are located in the protective cavity 416, and most of them are located inside the stirring tank 43; With such arrangement, the first rotating motor 414 controls the rotation of the first rotating shaft 412, and the first rotating shaft 412 drives the on-off piece 14 to rotate, completing the opening or closing operation of the connecting through hole 42. The protective cover 411 prevents dust from falling in, and protects the normal operation of the first rotating motor 414 and the second rotating motor 415. The second rotating motor 415 drives the second rotating shaft 413 to rotate through the transmission action of the gear 417, and the second rotating shaft 413 drives the storage tank 3 to rotate. The storage tank 3 is then used as a stirring fan blade to mix the reagents in the test stirring tank 43. A groove is provided at one end of the first rotating shaft 412 close to the on-off piece 14, and a plurality of through holes are provided on the outer wall of the groove. A second one-way valve 15 is provided at the groove, and the second one-way valve 15 ensures that the reagent flows out of the stirring tank 43 in one direction through the through hole.

[0029] Optionally, in some embodiments, please refer to Figure 5 The driving component 41 also includes a placement plate 418 and a stepper motor 419. The placement plate 418 is sleeved on the second rotating shaft 413 and is located in the stirring tank 43. The placement plate 418 and the stirring tank 43 are rotatable. The stepper motor 419 is arranged on the placement plate 418. A piston 7 is arranged in the storage tank 3, and the piston 7 is arranged at the output end of the stepper motor 419.

[0030] It can be understood that the placement plate 418 rotates synchronously with the second rotating shaft 413, the stepping motor 419 can be arranged on the placement plate 418 in a fixed connection manner, and the piston 7 is slidably connected in the inner wall of the storage tank 3; With such arrangement, the second rotating motor 415 drives the second rotating shaft 413 to rotate through the transmission action of the gear 417, and the second rotating shaft 413 drives the storage tank 3 to rotate. The storage tank 3 is now used as a stirring fan blade. At the same time, the placement plate 418 rotates driven by the second rotating shaft 413, and the stepper motor 419 on the placement plate 418 remains relatively still with the storage tank 3. The stepper motor 419 drives the piston 7 to move up and down. When the piston 7 moves upward, the reagent in the stirring tank 43 enters the storage tank 3 through the first one-way valve 8 and the exchange membrane 32. When the piston 7 moves downward, the reagent in the storage tank 3 enters the stirring tank 43 through the exchange membrane 32. This reciprocating process is carried out to achieve sufficient mixing of different reagents. After the mixing is completed, the stepper motor 419 controls the piston 7 to move downward to the maximum range, so that the reagent in the storage tank 3 can completely enter the stirring tank 43 for extraction and use.

[0031] Optionally, in some embodiments, please refer to Figure 5 A laser displacement sensor 11 is also provided on the placement plate 418, and the laser emission angle of the laser displacement sensor 11 is perpendicular to the piston 7. A fixed iron plate 12 is provided on the end of the piston 7 away from the storage tank 3. An electromagnetic lock 13 is provided at the output end of the stepper motor 419, and the fixed iron plate 12 is movably connected to the electromagnetic lock 13.

[0032] With such arrangement, when the electric push rod 9 of the reagent tank 2 starts to operate, the piston 7 gradually moves upward, and the laser displacement sensor 11 can accurately sense the displacement distance of the piston 7. In the process of the reagent tank 2 injecting liquid into the storage tank 3, the distance of the upward movement of the piston 7 is read by the laser displacement sensor 11, and the specific volume of the reagent in the storage tank 3 at this moment is calculated by the size of the internal space of the storage tank 3 and the displacement distance of the piston 7, or a specific value is input in advance. When the laser displacement sensor 11 senses that the piston 7 has reached the set displacement distance, the reagent tank 2 is controlled to stop injecting reagent into the storage tank 3; when the stepper motor 419 starts to work, it is necessary to drive the piston 7 to move, so it is necessary to fix the stepper motor 419 and the piston 7. During the downward movement of the output end of the stepper motor 419, it gets closer and closer to the piston 7, and the electromagnetic lock 13 is opened. When the electromagnetic lock 13 contacts the fixed iron plate 12, the two are fixedly connected. At this time, the stepper motor 419 can fully drive the piston 7 to move to achieve the effect of fully mixing the reagents.

[0033] Optionally, in some embodiments, please refer to Figure 2 as well as Figure 5A transfer box 16 is provided at the bottom of the stirring tank 43, and the transfer box 16 includes a box body 161, an air pump 162 and a connecting pipe 163. The air pump 162 is provided on the box body 161 and the output end of the air pump 162 is connected to the box body 161, one end of the connecting pipe 163 is connected to the second one-way valve 15, and the other end of the connecting pipe 163 is connected to the box body 161. The box body 161 is divided into two parts. The part of the box body 161 close to the air pump 162 is cylindrical, and the part of the box body 161 away from the air pump 162 is conical.

[0034] With such arrangement, after the different anesthetic agents are completely mixed, the air pump 162 starts to work, and the mixed agents pass through the through hole on the first rotating shaft 412, and then pass through the second one-way valve 15 and the connecting pipe 5 into the box 161. Since the part away from the air pump 162 is conical, the final anesthetic product is easier to gather and be collected for use. A liquid atomization device can also be additionally connected to the bottom of the box 161 to connect the anesthetic to the patient's respiratory system for inhalation anesthesia.

[0035] Optionally, in some embodiments, please refer to Figure 2-Figure 5 The storage tank 3 is connected to the second rotating shaft 413 through a fixing assembly 17. The fixing assembly 17 includes a connecting arm 171 and a placing ring 172. The connecting arm 171 is arranged on the second rotating shaft 413. The placing ring 172 is arranged on one end of the connecting arm 171 away from the second rotating shaft 413. The storage tank 3 is removably arranged on the placing ring 172.

[0036] It can be understood that since the storage tank 3 is removable, a friction ring needs to be provided on the inner wall of the placement ring 172 .

[0037] In this arrangement, the storage tank 3 is first slidably connected and fixed on the placement ring 172. A friction ring is placed on the inner wall of the placement ring 172. When the second rotating shaft 413 drives the connecting arm 171 to rotate, under the action of centrifugal force, the friction between the friction ring and the storage tank 3 increases. At this time, when the piston 7 moves, the storage tank 3 and the placement ring 172 will not produce relative displacement, thereby ensuring the mixing efficiency.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
