Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a concentration-adjustable anesthesia device for anesthesiology. Background Art

[0002] Ensuring that patients can smoothly undergo surgical treatment under painless and safe conditions is a basic task of clinical anesthesia, but this is only part of the work content of modern anesthesia. Anesthesia work also includes preparation and treatment before and after anesthesia, monitoring and treatment of critically ill patients, emergency resuscitation, pain treatment and other aspects. Among them, the concentration of anesthetics needs to be adjusted when anesthetizing patients. Too high a concentration of anesthetics will cause discomfort to the human body, may be toxic to the nerves, and have adverse effects on human health. When the concentration is too low, the patient is prone to wake up prematurely, increasing the patient's pain. Therefore, an anesthesia device is needed to adjust the concentration of the anesthetic.

[0003] For example, the concentration-adjustable anesthesia device for anesthesia department disclosed in the Chinese patent with authorization announcement number CN114931687B has the following working principle: "The push plate moves up to lift the valve plug through the push rod, and by controlling the distance the valve plug moves up, the L-shaped flow channel on the valve plug can overlap with the liquid outlet pipe to different sizes. When the overlapping area of ​​the L-shaped flow channel and the liquid outlet pipe is small, the flow in the liquid outlet pipe is small. When the overlapping area of ​​the L-shaped flow channel and the liquid outlet pipe is large, the flow in the liquid outlet pipe is large. Therefore, by controlling the distance the valve plug moves up, the flow in the liquid outlet pipe can be controlled; the push plate moves up to lift the valve plug through the push rod, and by controlling the distance the valve plug moves up, the flow in the liquid outlet pipe can be controlled. When the rod lifts the valve plug, the push rod will also squeeze the spring through the pressure plate. When the upward force is no longer applied to the push plate, the pressure plate, push rod and valve plug can quickly return to their original positions under the action of the spring and re-block the liquid outlet pipe. Therefore, within a stroke of the valve plug moving up to reset, by controlling the size of the overlapping area between the L-shaped flow channel in the valve plug and the liquid outlet pipe (i.e., the upward movement distance of the valve plug), the flow in the liquid outlet pipe can be accurately controlled, thereby controlling the ratio of the anesthetic and the diluent. The nut is synchronously adjusted by the rotation of the screw rod, thereby synchronously adjusting the shaft sleeve and the bump, thereby synchronously completing the liquid outlet flow of the liquid outlet pipe.

[0004] Among them, when changing the anesthetic concentration, the liquid flow rate discharged from the liquid outlet pipe is the same, and the required concentration cannot be accurately adjusted. Since the liquid flow rate is the same, the anesthetic concentration after dilution during the dilution process is the same, and the anesthetic concentration cannot be effectively diluted to the required concentration. Among them, after the anesthetic is discharged, the diluent will also be discharged. The discharge amount of the diluent cannot be controlled after the anesthetic is discharged, and the concentration of the anesthetic after dilution cannot be effectively controlled. Therefore, there is an urgent need for an adjustable concentration anesthesia device that is convenient for controlling the dilution concentration of the anesthetic. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Please refer to Figure 1-Figure 11 As shown, the present invention provides an anesthesia device with adjustable concentration for anesthesia department, comprising a fixing seat 1, a mixing barrel 3 and a tank body, wherein the tank body comprises a dilution tank 4 containing a diluent and an anesthesia tank 5 containing a medical anesthetic, wherein the bottom ends of the dilution tank 4 and the anesthesia tank 5 are both fixedly connected with a connecting pipe 51, and a guide pipe 511 which is in an inclined state and communicates with the mixing barrel 3 is provided on one side of the connecting pipe 51; The inner wall of the connecting pipe 51 is provided with a conducting mechanism that slides up and down to connect the tank body and the material guiding pipe 511, and the bottom end of the conducting mechanism extends out of the bottom end of the connecting pipe 51; A toothed plate 2 is rotatably arranged above the fixed seat 1, and the bottom end of the conducting mechanism rolls against the top surface of the toothed plate 2; The top and bottom surfaces of the tooth plate 2 are interlaced with an adjustment chain belt 9, the adjustment chain belt 9 above the tooth plate 2 is supported at the bottom end of the conduction mechanism in an eight-shaped structure, and the bottom surface of the tooth plate 2 is provided with a power mechanism for driving the top end of the adjustment chain belt 9 to move up and down.

[0020] In this case, the dilution tank 4 is equipped with a diluent, and the anesthesia tank 5 is equipped with an anesthetic, and the anesthetic and diluent in the anesthesia tank 5 and the dilution tank 4 can flow into the connecting tube 51, wherein a conducting mechanism that slides up and down is provided in the connecting tube 51, and the outer periphery of the conducting mechanism is in sealed sliding connection with the inner wall of the connecting tube 51, and the anesthetic and diluent will not leak out from between the conducting mechanism and the connecting tube 51 during the sliding process, and the conducting mechanism can be in two states during the sliding process: The first type: the anesthesia tank 5 is connected to the guide pipe 511 through the conduction mechanism, and the dilution tank 4 is connected to the guide pipe 511 through the conduction mechanism. In this state, the diluent and anesthetic in the dilution tank 4 and the anesthesia tank 5 can flow into the mixing barrel 3 through the guide pipe 511 and mix in the mixing barrel 3. At this time, the anesthetic is diluted to the required concentration; The second type: the anesthesia tank 5 is not connected to the guide pipe 511 through the conduction mechanism, and the dilution tank 4 is not connected to the guide pipe 511 through the conduction mechanism. At this time, the diluent and anesthetic in the dilution tank 4 and the anesthesia tank 5 can be blocked from being discharged through the guide pipe 511, effectively controlling the discharge amount of the diluent and anesthetic.

[0021] Among them, an adjustment chain belt 9 is arranged on the tooth plate 2 and is inserted and sleeved on the tooth plate 2, and the adjustment chain belt 9 located above the tooth plate 2 is in an eight-shaped structure, and a power mechanism for driving the top end of the adjustment chain belt 9 to move up and down is arranged on the bottom surface of the tooth plate 2. The height of the top end of the adjustment chain belt 9 can be changed by the power mechanism, thereby changing the inclination of the adjustment chain belt 9 above the tooth plate 2.

[0022] The effect of changing the inclination of the adjusting chain belt 9 above the tooth plate 2 is as follows: the tooth plate 2 can drive the adjusting chain belt 9 to move during the rotation. When the adjusting chain belt 9 is rotated to below the anesthesia tank 5 and is located below the conducting mechanism, the tooth plate 2 continues to rotate. At this time, the bottom end of the conducting mechanism will contact the adjusting chain belt 9. With the rotation of the tooth plate 2, the bottom end of the conducting mechanism can continuously climb toward the top of the adjusting chain belt 9. Since the adjusting chain belt 9 is an eight-shaped structure, the conducting mechanism can squeeze the conducting mechanism during the climbing process, so that the conducting mechanism moves upward, thereby connecting the conducting mechanism with the guide pipe 511, so that the anesthetic in the anesthesia tank 5 is introduced into the mixing barrel 3 through the guide pipe 511. The height of the top end of the adjusting chain belt 9 can change the inclination of the adjusting chain belt 9. When the adjusting chain belt 9 is adjusted to the highest position, when the conducting mechanism moves to the top end of the adjusting chain belt 9, the conducting mechanism can be fully connected with the guide tube 511, so that the flow speed of the liquid reaches the maximum, and the liquid can be quickly discharged into the mixing barrel 3. By changing the inclination of the adjusting chain belt 9, the flow rate of the liquid can be effectively controlled to control the amount of liquid discharged, and the required liquid can be introduced into the mixing barrel 3 within a unit time. Among them, when the adjusting chain belt 9 is rotated to the bottom of the dilution tank 4 and is located below the conducting mechanism, the above process is repeated, which can effectively control the amount of liquid discharged into the mixing barrel 3 to control the dilution concentration of the anesthetic.

[0023] Among them, by adjusting the chain belt 9 to be arranged in an eight-shaped structure above the tooth plate 2, and the height of the top of the adjustable chain belt 9 can be changed, when the conducting mechanism moves on the adjustable chain belt 9, the displacement of the conducting mechanism moving upward can be changed, thereby controlling the amount of anesthetic and diluent discharged into the mixing barrel 3, so as to dilute the anesthetic to the required concentration and improve the use efficiency.

[0024] The anesthetic and the diluent can be prevented from being discharged at the same time, and the anesthetic and the diluent can be discharged into the mixing barrel 3 in proportion for mixing, wherein the process of achieving proportional discharge is as follows: the rotation speed of the tooth plate 2 in unit time is the same, the tooth plate 2 rotates slowly for one circle, and the time it takes to pass under the dilution tank 4 and under the anesthetic tank 5 is the same, and the flow rate of the anesthetic and the diluent during the discharge process is controlled by changing the inclination of the adjustment chain belt 9. The smaller the flow rate, the less the amount discharged in unit time, and the larger the flow rate, the more the amount discharged in unit time, thereby achieving proportional discharge of the anesthetic and the diluent, so as to dilute the anesthetic to the required concentration.

[0025] A connecting support plate 34 is fixedly sleeved around the connecting pipe 51 and the outer periphery of the mixing barrel 3. A third support rod 33 is fixedly connected between the bottom end of the mixing barrel 3 and the fixing seat 1. A through hole sleeved around the outer periphery of the mixing barrel 3 is opened at the center of the tooth plate 2.

[0026] By setting the connecting support plate 34, the mixing barrel 3, the dilution tank 4 and the anesthesia tank 5 can be integrated, and the stability of the mixing barrel 3 can be increased by the third support rod 33, thereby supporting the anesthesia tank 5 and the dilution tank 4 to ensure their stability.

[0027] A bearing 22 is fixedly disposed on the bottom surface of the toothed plate 2 near the through hole, and a first support rod 221 is fixedly disposed between the inner ring of the bearing 22 and the fixed seat 1 .

[0028] By disposing the bearing 22 and fixing a first support rod 221 between the inner ring of the bearing 22 and the fixing seat 1 , the tooth plate 2 can be supported without affecting the rotation of the tooth plate 2 , thereby ensuring the stable rotation of the tooth plate 2 .

[0029] The conducting mechanism includes a guide plate 512, a sealing plug 7, a pressure rod 72 and a spring 73. The sealing plug 7 is sealingly and slidingly arranged on the inner wall of the connecting tube 51. A feeding hole 71 connected to the guide tube 511 is opened in the sealing plug 7. The cross-section of the feeding hole 71 is L-shaped, and the top end passes through the sealing plug 7. The guide plate 512 is fixedly connected to the inner wall of the connecting tube 51 near the bottom end. The spring 73 is fixedly connected between the guide plate 512 and the sealing plug 7. The pressure rod 72 is sleeved in the spring 73. The top end of the pressure rod 72 is fixedly connected to the bottom end of the sealing plug 7, and the bottom end of the pressure rod 72 passes through the guide plate 512 and is fixedly connected to a walking wheel 721. The pressure rod 72 is slidably connected to the guide plate 512.

[0030] By setting the sealing plug 7, the sealing plug 7 is sealingly slidably set in the connecting tube 51. When the tooth plate 2 is in a rotating state, the walking wheel 721 walks on the top surface of the tooth plate 2. When the walking wheel 721 starts to climb the adjusting chain belt 9 of the figure eight structure, it will generate pressure on the pressure rod 72, so that the pressure rod 72 squeezes the sealing plug 7, so that the sealing plug 7 slides upward in the connecting tube 51, so that the discharge hole 71 is connected with the guide tube 511. As the walking wheel 721 continues to climb, the range of communication between the discharge hole 71 and the guide tube 511 can be increased, and the liquid flow rate can be increased, so as to facilitate the introduction of the required anesthetic and diluent into the mixing barrel 3. When the inclination of the adjusting chain belt 9 is changed, the range of communication between the discharge hole 71 and the guide tube 511 can be changed, thereby controlling the amount of anesthetic and diluent flowing out, so as to dilute the anesthetic to the required concentration.

[0031] Among them, when the walking wheel 721 climbs to the highest point of the adjusting chain belt 9, the sealing plug 7 moves upward to the highest point in the connecting tube 51. At this time, the spring 73 is in a stretched state. Then, with the rotation of the tooth plate 2, the walking wheel 721 can move downward along the inclined surface of the adjusting chain belt 9. At this time, under the action of the spring 73, the pressure rod 72 can move downward and pull the sealing plug 7 downward until the discharge hole 71 is no longer connected with the guide tube 511. At this time, the discharge of anesthetics and diluents can be blocked, and the top of the sealing plug 7 is an arc-shaped structure to facilitate the flow of anesthetics and diluents toward the discharge hole 71.

[0032] A driving mechanism for driving the toothed plate 2 to rotate is arranged on the top surface of the fixed seat 1, and the driving mechanism includes an adjusting motor 11 and a first gear 112.

[0033] A stirring rod 32 is rotatably arranged in the mixing barrel 3, and the bottom end of the stirring rod 32 passes through the mixing barrel 3 and is rotatably arranged on the top surface of the fixed seat 1. A connecting mechanism is provided on the outer periphery of the stirring rod 32 and the power output end of the adjusting motor 11. The connecting mechanism includes a first roller 111, a belt 113 and a second roller 321. The first roller 111 is fixedly connected to the outer periphery of the power output end of the adjusting motor 11, and the second roller 321 is fixedly connected to the outer periphery of the stirring rod 32. The belt 113 is sleeved on the outer peripheries of the first roller 111 and the second roller 321, and the belt 113 is located below the power mechanism.

[0034] By adjusting the start of the motor 11, the first roller 111 and the first gear 112 can be driven to rotate. The first gear 112 is meshed with the outer periphery of the tooth plate 2, so the first gear 112 can drive the tooth plate 2 to rotate, wherein the belt 113 is located below the power mechanism, which can prevent the tooth plate 2 from touching the belt 113 during rotation to prevent affecting the rotation of the tooth plate 2, wherein the first roller 111 can drive the belt 113 to rotate during rotation, and the belt 113 drives the second roller 321 to rotate, thereby driving the stirring rod 32 to rotate through the second roller 321, so that the stirring rod 32 stirs the anesthetic and the diluent in the mixing barrel 3 to make them fully mixed, wherein a concentration sensor is provided in the mixing barrel 3, which can detect the concentration of the diluted anesthetic in the mixing barrel 3 in real time, so as to facilitate diluting the anesthetic to the required concentration.

The two ends of the adjusting chain belt 9 are fixedly connected to the connecting component, and the connecting component is located below the tooth plate 2.

[0036] By setting the first limiting roller 93, the second limiting roller 94 and the third limiting roller 95, and all of them are arranged in the adjusting chain belt 9, the adjusting chain belt 9 is in the shape of a house, and the adjusting chain belt 9 located above the tooth plate 2 is in an eight-shaped structure, which is also convenient for adjusting the adjusting chain belt 9.

[0037] The connecting component includes a first adjusting plate 91 and a second adjusting plate 92. One end of the adjusting chain 9 is fixedly connected to the first adjusting plate 91, and the other end is fixedly connected to the second adjusting plate 92. The second adjusting plate 92 is slidably sleeved on the periphery of the first adjusting plate 91. An electric telescopic rod 914 is arranged between the top surface of the first adjusting plate 91 and the top surface of the second adjusting plate 92 and the bottom surface of the tooth plate 2 through a lifting ear. Second slide grooves 911 are provided on both sides of the first adjusting plate 91 and the second adjusting plate 92. A supporting mechanism is arranged between the second slide groove 911 and the tooth plate 2. The supporting mechanism includes a second support rod 231 and a positioning block 96.

One end of the second support rod 231 is fixedly connected to the positioning block 96, and the positioning block 96 is slidably arranged in the second slide groove 911.

[0038] By setting the first adjustment plate 91 and the second adjustment plate 92, the adjustment chain 9 can be pulled so that the adjustment chain 9 is in a straight state to avoid looseness. When the walking wheel 721 climbs on the adjustment chain 9, the adjustment chain 9 can be prevented from collapsing.

[0039] Among them, through the setting of the electric telescopic rod 914, the sleeve state of the first adjustment plate 91 and the second adjustment plate 92 can be changed to facilitate changing the height of the third limiting roller 95, wherein a cross-shaped fixing plate 23 is fixedly arranged between the second support rod 231 and the tooth plate 2 to increase the stability of the support, and the first adjustment plate 91 and the second adjustment plate 92 can be limited by the action of the second support rod 231 and the positioning block 96 to ensure the horizontal displacement of the first adjustment plate 91 and the second adjustment plate 92 to ensure the height adjustment of the third limiting roller 95.

[0040] The linkage components include a threaded rod 8, an adjusting nut 81, a first rack 913 and a second rack 921.
