Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary instruments for anesthesia department, and in particular relates to an anesthetic drug spray device. Background Art

[0002] Nowadays, when performing local anesthesia on the throat, anesthetic drugs are usually sprayed directly on the surface of the throat mucosa through an anesthetic spray device, so that the drug can quickly cover the area that needs anesthesia, such as the existing public patent (application number CN202110895091.X) for a quantitative spray device for throat anesthesia used by the anesthesia department.

[0003] When the above-mentioned anesthetic spray device is used to anesthetize the throat, since the storage tank can only store one concentration of anesthetic drugs, it is not convenient for medical staff to select anesthetic drugs of corresponding concentrations according to different patient conditions during daily use, which brings inconvenience to the anesthesia work. At the same time, when the above-mentioned anesthetic spray device atomizes the anesthetic liquid, it squeezes the anesthetic liquid through micropores and sprays it to the throat. Since the anesthetic liquid is subjected to the squeezing force and sprayed from the micropores, the impact force generated is relatively large, which can easily cause the patient's throat to be strongly stimulated, especially for patients with sensitive throats and weak tolerance, which may cause coughing, nausea and other uncomfortable reactions.

[0004] Therefore, we propose an anesthetic spray device to solve the above problems. Summary of the invention

[0014] Compared with the existing technology, the advantages of an anesthetic spray device are: 1. By setting up multiple anesthesia storage tanks distributed in an annular shape and at equal intervals in the storage box, as well as the matching position adjustment and fluid replenishment components and docking quantitative infusion components, the convenience and accuracy of the use of anesthetic drugs are greatly improved. The worm, worm wheel, and stepper motor in the position adjustment and fluid replenishment components cooperate with each other. Medical staff can easily rotate the rotating seat with the help of the PLC controller to adjust the storage tank of anesthetic drugs of the required concentration to the appropriate position. At the same time, the design of the liquid distribution tube and the second solenoid valve makes the fluid replenishment operation more flexible, and the anesthetic liquid of the corresponding concentration can be added to different storage tanks as needed. The photoelectric transmitter, photoelectric receiver, electric push rod, telescopic tube and metering pump in the docking quantitative infusion component work together. When the storage tank is rotated into place, the photoelectric sensor will automatically control the telescopic tube to accurately dock with the docking liquid guide seat, and the metering pump can accurately control the amount of anesthetic liquid extracted into the atomization chamber to meet the needs of different patients for anesthetic drug concentration and dosage.

[0015] 2. By setting an atomization component consisting of an ultrasonic atomizer, a stirring blade, a micro-drive motor, etc. in the atomization chamber, efficient atomization of the anesthetic liquid is achieved. The ultrasonic atomizer uses the principle of high-frequency oscillation to break up the liquid into uniform and fine atomized particles. These particles are easier to suspend in the air and can cover all parts of the patient's throat more deeply and widely. Compared with the traditional extrusion microporous atomization method, the atomized particles produced by this device are less irritating to the throat, effectively improving the patient's comfort during anesthesia. Driven by the micro-drive motor, the shaft drives the stirring blade to rotate through the bevel gear set. The stirring process can not only make the anesthetic liquid in various places better diffuse to the ultrasonic atomizer, improve the atomization efficiency, but also promote the full dissolution of undissolved particles, further improve the overall atomization quality, and ensure the stability and reliability of the anesthesia effect.

[0016] 3. By setting an intermittent opening and closing control component and a button switch in the atomization chamber, the applicability of the device to different patients is significantly enhanced. The extrusion slider in the intermittent opening and closing control component rotates with the operation of the micro-drive motor, intermittently squeezing the first arc pressure sensor, so that the PLC controller controls the first solenoid valve to open intermittently, and then the atomization catheter intermittently sprays atomized liquid. This method is particularly suitable for patients with weak tolerance, such as children and the elderly. Multiple small-dose sprays can effectively reduce the risk of drug accumulation and avoid systemic adverse reactions such as dizziness and respiratory depression caused by a single overdose. For patients with strong tolerance, only need to press the button switch to close the normally open contact to control the first solenoid valve to open continuously, so as to achieve continuous spray anesthesia and speed up the anesthesia process to meet the anesthesia needs of different patients.

[0017] 4. By arranging the suction air guide fan, filter, spring electromagnetic telescopic rod and knocking ball and other components in the atomization chamber, the smoothness and safety of the spray are guaranteed. The suction air guide fan can generate suction when working to assist the atomized medicine liquid to smoothly enter the atomization duct. The filter can effectively intercept the large particles of medicine and impurities that are not completely atomized in the atomized liquid to prevent them from flowing into the patient's throat to ensure the safety of the patient. The spring electromagnetic telescopic rod and the knocking ball cooperate with the filter. The second arc pressure sensor in the annular trigger groove feeds back a signal to the PLC controller under the intermittent squeezing of the squeezing slider, controls the intermittent expansion and contraction of the spring electromagnetic telescopic rod, and then drives the knocking ball to intermittently knock on the filter, so that the large particles of medicine adhering to the filter fall off and are atomized again by the atomization component, which not only ensures the permeability of the filter but also improves the utilization rate of the medicine.

In the actual use process, a liquid level sensor can be set on the anesthesia storage tank 4 to monitor the liquid storage amount of the anesthesia storage tank 4.

[0023] The upper side of the storage box 1 is provided with a docking quantitative infusion assembly 6 that matches each anesthesia storage tank 4. The docking quantitative infusion assembly 6 includes a telescopic tube 61, two electric push rods 62, a fixed plate 63 and a metering pump 64. The telescopic tube 61, the two electric push rods 62 and the metering pump 64 are all fixedly arranged on the upper side of the storage box 1.

The docking liquid guide seat 15 is fixedly connected to the lower side of the corresponding anesthesia storage tank 4 through a low-position liquid extraction tube 17, and a photoelectric receiver is fixedly arranged on the fixed plate 63. 18, and each anesthetic storage tank 4 is fixedly provided with a photoelectric transmitter 19 matched with the photoelectric receiver 18, the input end of the metering pump 64 is connected with the fixed end of the telescopic tube 61 through the suction tube 20, and the output end of the metering pump 64 is connected with the atomization bin 7 through the delivery tube 21, the electric push rod 62, the photoelectric receiver 18, the photoelectric transmitter 19 and the metering pump 64 are all electrically connected with the PLC controller 2, and through the set photoelectric transmitter 19, when the required anesthetic storage tank 4 is rotated into place, the trigger electrical signal can be fed back by the photoelectric transmitter 19, so that the PLC controller 2 controls the electric push rod 62 to start automatically, so that the electric push rod 62 automatically controls the telescopic tube 61 to dock with the corresponding docking liquid guide seat 15, and the setting of the metering pump 64 is convenient for accurately controlling the amount of anesthetic liquid used during the anesthesia process.

[0024] The output end of the docking quantitative infusion component 6 is fixedly connected to the atomization bin 7, the atomization bin 7 is fixedly arranged on the upper side of the storage box 1, and a drainage pipe 8 is arranged on the atomization bin 7, a first solenoid valve 9 is arranged on the drainage pipe 8, and a atomization conduit 10 is fixedly connected to the drainage pipe 8, an atomization component 11 is arranged in the atomization bin 7, the atomization component 11 includes a stirring blade 111, a plurality of ultrasonic atomization sheets 112, a bevel gear set 113, a rotating shaft 114 and a micro-drive motor 115, the stirring blade 111 is rotatably arranged in the atomization bin 7, and a driving cavity 28 matching the stirring blade 111 is opened on the lower side of the atomization bin 7, the micro-drive motor 115 is fixedly arranged in the driving cavity 28, and the output end of the micro-drive motor 115 is fixedly connected to the rotating shaft 114, the transmission shaft of the stirring blade 111 extends into the driving cavity 28 and is transmission-connected to the rotating shaft 114 through the bevel gear set 113, and each ultrasonic atomization sheet 112 is fixedly arranged It is placed on the inner bottom surface of the atomization bin 7, and each ultrasonic atomization sheet 112 is distributed in a ring shape. Each ultrasonic atomization sheet 112 and the micro-drive motor 115 are electrically connected to the PLC controller 2. Through the ultrasonic atomization sheet 112, the medicine liquid can be broken up into extremely uniform and fine atomized particles. Compared with the particles of different sizes and possibly larger particles produced by extrusion micropore atomization, such uniform and fine particles are easier to suspend in the air and can reach various parts of the throat more deeply and widely. The atomization process is relatively gentle, and the tiny particles produced slowly enter the throat with the airflow, which has less stimulation to the throat and relatively high comfort for the patient. Through the transmission cooperation of the micro-drive motor 115, the rotating shaft 114 and the bevel gear set 113, the stirring blade 111 can rotate and stir the medicine liquid while the ultrasonic atomization sheet 112 is working, so that the medicine liquid can be better atomized by the ultrasonic atomization sheet 112.

[0025] An intermittent opening and closing control component 12 matched with the first solenoid valve 9 is arranged in the atomizing bin 7, and the intermittent opening and closing control component 12 comprises an annular triggering chute 121, a first arc pressure sensor 122 and an extrusion slider 123, the annular triggering chute 121 is arranged on one side inner wall of the driving chamber 28, and the first arc pressure sensor 122 is embedded in the annular triggering chute 121, and the arc length of the first arc pressure sensor 122 is one quarter of the circumference of the annular triggering chute 121, the extrusion slider 123 is fixedly connected to the rotating shaft 114, and the end of the extrusion slider 123 away from the rotating shaft 114 is slidably connected to the annular triggering chute 121, and the first arc pressure sensor 122 is embedded in the annular triggering chute 121. An arc pressure sensor 122 is electrically connected to the PLC controller 2, and the first solenoid valve 9 can be controlled to open and close by the PLC controller 2 based on the electrical signal fed back by the first arc pressure sensor 122. The extrusion slider 123 provided can rotate in coordination with the operation of the micro drive motor 115, intermittently squeezing the first arc pressure sensor 122, so that the first arc pressure sensor 122 intermittently feeds back electrical signals to the PLC controller 2, and then the PLC controller 2 intermittently controls the opening and closing of the first solenoid valve 9, so that the nebulizer catheter 10 can intermittently spray nebulized liquid, giving patients with weaker tolerance a certain adaptation buffer period.

[0026] A button switch 22 cooperating with the first solenoid valve 9 is provided on the atomization chamber 7, and the normally open contact of the button switch 22 is connected in parallel to the signal line fed back to the PLC controller 2 by the first arc pressure sensor 122. By setting the button switch 22, the first solenoid valve 9 can be controlled to be normally open when the patient has a strong tolerance to anesthesia, so that the atomization catheter 10 continuously outputs atomized liquid medicine to speed up the anesthesia process, thereby greatly improving the scope of application of the device.

[0027] A suction air guide fan 23 is fixedly provided on the upper inner wall of the atomization chamber 7, and the output port of the suction air guide fan 23 is arranged opposite to the port of the drain pipe 8. The suction air guide fan 23 can assist the atomized liquid to enter the atomization conduit 10.

[0028] A filter screen 24 is fixedly arranged in the atomizing bin 7, and the filter screen 24 is located at the lower side of the suction air guide fan 23. Two spring electromagnetic telescopic rods 25 matched with the filter screen 24 are fixedly arranged in the atomizing bin 7, and a knocking ball 26 in contact with the filter screen 24 is fixedly arranged at the output end of the spring electromagnetic telescopic rod 25. The spring electromagnetic telescopic rod 25 is composed of a hollow main rod, a secondary rod, an electromagnetic block, a permanent magnet block and a reset spring. The secondary rod is slidably connected to the hollow main rod through the permanent magnet block. The electromagnetic block is fixedly arranged in the hollow main rod, and the electromagnetic block is fixedly connected to the permanent magnet block through the reset spring. The electromagnetic block is intermittently turned on and off, so that the electromagnetic block intermittently attracts the permanent magnet block, thereby controlling the intermittent extension and retraction of the secondary rod; Two second arc pressure sensors 27 are embedded in the annular trigger chute 121, and the arc length of the second arc pressure sensor 27 is one eighth of the circumference of the annular trigger chute 121. The second arc pressure sensor 27 and the spring electromagnetic telescopic rod 25 are both electrically connected to the PLC controller 2, and the spring electromagnetic telescopic rod 25 can be controlled to open and close by the PLC controller 2 based on the electrical signal fed back by the second arc pressure sensor 27. The atomized liquid flowing into the atomization catheter 10 can be filtered through the filter 24 to prevent impurities or large particles of drugs that are not completely atomized from flowing into the patient's throat. At the same time, the second arc pressure sensor 27 can cooperate with the intermittent extrusion of the extrusion slider 123, so that the second arc pressure sensor 27 intermittently feeds back electrical signals to the PLC controller 2, thereby allowing the PLC controller 2 to intermittently control the spring electromagnetic telescopic rod 25 to intermittently extend and retract, thereby allowing the knocking ball 26 to intermittently knock on the filter 24, so that the large particles of drugs adhered to the filter 24 can fall off and be atomized again by the atomization component 11.

[0029] The operating principle of the present invention is now described as follows: When performing anesthesia in the throat, first, according to the patient's condition, an anesthesia storage tank 4 storing an anesthetic solution of the required concentration is selected. During the selection process, the stepper motor 56 and the photoelectric transmitter 19 on the required anesthesia storage tank 4 are controlled by the PLC controller 2 to start. After the stepper motor 56 is started, it will cooperate with the worm 54 and the worm gear 55 to control the rotating seat 3 to rotate a certain angle, so that the required anesthesia storage tank 4 moves to the bottom of the telescopic tube 61. After rotating in place, the PLC controller 2 will control the stepper motor 56 to automatically stop. At the same time, the photoelectric transmitter 19 will be located directly below the photoelectric receiver 18. The light emitted by the photoelectric transmitter 19 will trigger the photoelectric receiver 18 to feedback an electrical signal to the PLC controller 2, so that the PLC controller 2 controls the output ends of the two electric push rods 62 to extend a certain length, thereby causing the sliding end of the telescopic tube 61 to automatically dock with the port of the docking liquid guide seat 15 on the required anesthesia storage tank 4. After the docking is completed, the discharge end of the atomization catheter 10 is inserted into the throat part of the patient that needs anesthesia, and then the metering pump 64 is controlled to start by the PLC controller 2. According to the preset program of the PLC controller 2, the metering pump 64 automatically sucks the required amount of anesthetic liquid into the atomization bin 7. After the suction is completed, the PLC controller 2 will turn off the metering pump 64, and control the micro-drive motor 115, the ultrasonic atomization sheet 112 and the suction air guide fan 23 to start. After the ultrasonic atomization sheet 112 is started, it uses high-frequency oscillation to break up the liquid medicine into extremely uniform and fine atomized particles. At the same time, the suction air guide fan 23 will slowly guide the generated atomized liquid medicine into the atomization catheter 10 through the airflow, and slowly spray it out from the discharge end of the atomization catheter 10, gently acting on the throat part of the patient, avoiding discomfort to the patient during the anesthesia process; After the micro drive motor 115 is started, the bevel gear set 113 is used to control the stirring blade 111 to rotate, so that the anesthetic liquid in various places can be stirred and diffused to the ultrasonic atomization sheet 112, thereby improving the atomization effect of the ultrasonic atomization sheet 112. At the same time, during the stirring process, the undissolved particles can be better dissolved, and the filter screen 24 in the atomization bin 7 can intercept the large particles of the drug that are not completely atomized in the atomized liquid, so as to ensure the quality of the atomized liquid exported by the atomization catheter 10; Driven by the micro-drive motor 115, the extrusion slider 123 intermittently squeezes the first arc pressure sensor 122 and the second arc pressure sensor 27, so that the first arc pressure sensor 122 and the second arc pressure sensor 27 intermittently feedback electrical signals, thereby causing the PLC controller 2 to intermittently control the first electromagnetic valve 9 and the spring electromagnetic telescopic rod 25 to intermittently open and close. During the intermittent opening and closing of the first electromagnetic valve 9, the atomization catheter 10 will intermittently spray atomized liquid. Through multiple small-dose sprays, the risk of drug accumulation is reduced. For patients with weak tolerance, such as children and the elderly, systemic reactions such as dizziness and respiratory depression caused by a single overdose can be avoided. For patients with strong tolerance, the normally open contact of the button switch 22 can be controlled to close, so that the PLC controller 2 can continuously receive the opening signal, so that the PLC controller 2 controls the first electromagnetic valve 9 to be continuously opened, thereby allowing patients with strong tolerance to receive continuous spray anesthesia to speed up the anesthesia process. During the intermittent opening and closing process of the spring electromagnetic telescopic rod 25, the internal electromagnetic element will be intermittently energized, and then in cooperation with the internal spring, the spring electromagnetic telescopic rod 25 will be intermittently extended and retracted, so that the knocking ball 26 can intermittently knock on the filter 24, so that the filter 24 can shake off the adhered large particles of medicine under the action of vibration, while ensuring the permeability of the filter 24, the large particles of medicine that are not completely atomized can be atomized again by the atomization component 11.
