[0002] Local anesthesia, also known as regional anesthesia, refers to applying local anesthetics to a local part of the body while the patient is conscious, temporarily blocking the sensory nerve conduction function of a certain part of the body, while keeping the motor nerve conduction intact or having varying degrees of blockage at the same time. The advantages of local anesthesia are simple and easy to perform, safe, the patient remains conscious, and it has little impact on the patient's physiological functions.
[0003] When anesthetizing a patient, an indwelling needle is often used on the patient. During the operation, the anesthesiologist will continuously or intermittently administer anesthetic drugs according to the type of operation, the patient's physical condition, and the anesthesia method to maintain an appropriate depth of anesthesia. In the Chinese patent with the application number 202321671772.9 and the name "A Local Anesthesia Device", the drug infusion pump of this patent uses a rechargeable water pump. There is a medicine inlet at the lower end of the syringe. The infusion pump and the syringe are connected through a specially designed corrugated hose.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0023] 1. There is a multi-angle precise injection component. The syringe is placed inside the fixed frame, and then two annular rubber bands are sleeved on both ends of the syringe by using the fixed groove, which is convenient for installation;
[0024] By rotating the bidirectional screw rod, the fixed sliders are driven to approach each other inside the fixed slide rail. The clamping blocks are embedded into the fixed holes, and the clamping plates firmly fix the handle. After the fixation is completed, the syringe is driven to move by controlling the electric rail. The fixed pin is inserted into the corresponding docking male hole and docking female hole. By controlling the angle of the rotating flat head, the angle of the syringe needle is controlled. The syringe needle can be inserted into the medicine inlet of the indwelling needle. The syringe is driven to lift and lower by cooperating with the lifting cylinder. The device can move flexibly according to the position where the anesthetic is administered, and has a wide range of applications;
[0025] When continuously injecting through the indwelling needle, the pushing motor drives the pushing piece to move. The device can control the feeding amount and feeding speed of the liquid medicine as required, without the anesthesiologist always holding the syringe to supplement the anesthetic, greatly reducing the labor intensity of the anesthesiologist. And by controlling the operation of the pushing motor, the feeding amount and feeding speed of the anesthetic can be controlled more precisely, and the anesthetic effect is better;
[0026] When intramuscularly injecting a patient, the positioning suction cup is adsorbed on the patient's skin surface. The transparent rubber can observe the position of the needle, and the needle can be quickly positioned. During injection, pressure is applied to the extruded transparent rubber. The transparent rubber and the return spring are compressed, and the needle is inserted into the patient's body. After the injection is completed, the pressure is removed and the return spring rebounds, and the needle is removed from the patient's body, making the injection more convenient and rapid;
[0027] When a doctor needs to go out for medical treatment by ambulance, the doctor can hold the handle alone to move. The medicine can be prepared in advance on the ambulance. After the syringe draws the liquid medicine, the heat preservation electric hot plate is started in advance. The heat preservation electric hot plate emits heat to heat and keep warm the liquid medicine inside the syringe. When the doctor arrives at the scene, the patient can be quickly anesthetized, with a wide range of applications, convenience and rapidity.
[0028] 2. There is a liquid medicine mixing and heating component. When preparing the medicine, the infusion bottle containing the mixture is placed on the top of the placing tray. By controlling the docking electric push rod, the clamping arc plates are driven to approach each other to center and fix the infusion bottle. After the infusion bottle is fixed, the swinging electric push rod drives the swinging rack to move back and forth, driving the swinging gear, the placing tray and the infusion bottle to swing back and forth, realizing the full mixing of the high-concentration anesthetic agent and physiological saline. There is no need to manually shake the infusion bottle for mixing, reducing the manual labor intensity. The anesthetic liquid medicine for multiple people can be prepared inside the infusion bottle, and one preparation can be used for multiple people, without the doctor preparing the anesthetic liquid medicine multiple times, further reducing the manual labor intensity;
[0029] By starting the medicine extraction pump and heating the electric hot plate, the liquid medicine inside the infusion bottle flows through the medicine extraction tube, the medicine extraction pump, and the medicine outlet tube in sequence and enters the inner part of the lower liquid box, and then flows through the liquid separation tube into the inner part of the upper liquid box. When the liquid medicine flows through the liquid separation tube, the liquid separation tube increases the heat conduction area of the liquid medicine, and the heat generated by the heating electric hot plate can quickly heat the liquid medicine, so that the anesthetic liquid medicine reaches the appropriate temperature required by the human body. Then the medical staff extracts the heated liquid medicine, which can reduce the discomfort of the patient when injecting the liquid medicine subsequently;
[0030] The three control buttons respectively control the delivery liquid volume of 5ml, 10ml, and 15ml anesthetics. When it is necessary to inject anesthetics at multiple positions of a person, the quantitative medicine tube is directly connected to the syringe. By pressing the control button, the medicine extraction pump can directly and quantitatively deliver the anesthetic liquid medicine inside the infusion bottle to the inside of the syringe, without repeatedly extracting the liquid medicine for anesthetic injection, reducing the manual labor intensity.
[0031] In summary, in the liquid medicine mixing and heating assembly, when the liquid medicine flows through the liquid separation tube, the liquid separation tube diverts the liquid medicine, increasing the heat conduction area of the liquid medicine and quickly heating the liquid medicine to the required temperature. In the multi-angle precise injection assembly of the liquid medicine, the heat preservation electric hot plate can heat and keep warm the liquid medicine inside the syringe, and can always maintain the temperature of the liquid medicine during the transfer process of the syringe and the subsequent injection process. When injecting the liquid medicine, it can reduce the discomfort of the patient to the greatest extent, and there are two operation methods, which are suitable for use in different situations, and the operation is more comprehensive and reasonable, and is suitable for popularization and use.

A fixing pin 207 is embedded between the two docking male holes 205 and docking female holes 206. The diameters of the docking male holes 205 and docking female holes 206 are equal. There is a clearance fit between the fixing pin 207 and the docking male hole 205. When the fixing pin 207 is inserted into the docking male hole 205 and the docking female hole 206, the rotating flat head 204 and the rotating base 203 can be stably fixed, enabling the rotating flat head 204 to be fixed at multiple angles inside the rotating base 203. At the top of the rotating flat head 204, a fixed slide rail 208 is installed. At both ends inside the fixed slide rail 208, fixed sliders 209 are slidably installed. Inside the fixed slide rail 208, a bidirectional screw 210 is rotatably installed. Both ends of the bidirectional screw 210 are respectively connected to the two fixed sliders 209 through threaded holes. The outer side of the fixed slider 209 is in contact with the inner side of the fixed slide rail 208. When the bidirectional screw 210 rotates, it can drive the fixed slider 209 to stably move inside the fixed slide rail 208. The outer side of the fixed slider 209 and the inner side of the fixed slide rail 208 are both smooth surfaces, reducing the frictional resistance between the fixed slider 209 and the fixed slide rail 208. One end of the bidirectional screw 210 is connected to a rotating head 211. The top of the fixed slider 209 is connected to a clamping plate 212. On the opposite surfaces of the two clamping plates 212, two clamping blocks 213 are welded;

When it is necessary to inject anesthetic at multiple positions of multiple people, the quantitative medicine tube 314 is directly connected to the syringe 220, and there is no need to draw the liquid medicine back and forth for anesthetic injection, reducing the manual labor intensity;
[0058] On both sides of the medicine pumping pump 303 on the top of the dust-proof box 301, support columns 315 are installed. On the top of one side of the support column 315, a docking electric push rod 316 is installed. The output end of the docking electric push rod 316 is connected to an arc-shaped frame 317. Inside the arc-shaped frame 317, a heating electric hot plate 318 is installed;
[0059] At the inner bottom of the dust-proof box 301, a lifting electric push rod 319 is installed. The output end of the lifting electric push rod 319 is connected to an assembly plate 320. In the middle of the top of the assembly plate 320, a swing gear 321 is rotatably installed. On one side of the swing gear 321 at the top of the assembly plate 320, a swing electric push rod 322 is installed. The output end of the swing electric push rod 322 is connected to a swing rack 323. The swing rack 323 meshes with the swing gear 321. The top of the swing gear 321 is connected to the middle of the bottom of the placement tray 302. On both sides of the top of the placement tray 302, clamping electric push rods 324 are installed. The output ends of the clamping electric push rods 324 are connected to clamping arc plates 325. Place the infusion bottle containing the anesthetic agent between the two clamping arc plates 325. Controlling the clamping electric push rods 324 to drive the clamping arc plates 325 to approach each other can center and fix the infusion bottle. A rubber pad 326 is bonded to the top end of the clamping arc plate 325. The rubber pad 326 buffers the clamping force to prevent the clamping arc plate 325 from damaging the infusion bottle;
[0060] The input ends of the electric rail 202, the medicine extraction pump 303, the docking electric push rod 316, the heating electric hot plate 318, the lifting electric push rod 319, the swing electric push rod 322 and the clamping electric push rod 324 are electrically connected to the output end of the external power supply. The input ends of the electric rail 202, the medicine extraction pump 303, the docking electric push rod 316, the heating electric hot plate 318, the lifting electric push rod 319, the swing electric push rod 322 and the clamping electric push rod 324 are electrically connected to the output end of the external power supply through an external controller. By controlling the external controller, the above electrical components can be controlled.
[0061] The working principle and usage process of the present invention: When in use, the high-concentration anesthetic agent and physiological saline are transported into the infusion bottle according to the required ratio. Place the infusion bottle containing the mixture on the top of the placement tray 302. Start the docking electric push rod 316. The docking electric push rod 316 drives the clamping arc plates 325 to approach each other to center and fix the infusion bottle. After the infusion bottle is fixed, start the swing electric push rod 322. The swing electric push rod 322 drives the swing rack 323 to move back and forth, and then drives the swing gear 321, the placement tray 302 and the infusion bottle to swing back and forth. The back-and-forth swing of the infusion bottle makes the high-concentration anesthetic agent and physiological saline in the bottle fully mixed to form the diluted required anesthetic liquid medicine, eliminating the need for manual shaking of the infusion bottle for mixing, reducing the manual labor intensity, and achieving a better liquid medicine mixing effect. After the full mixing is completed, start the lifting electric push rod 319. The lifting electric push rod 319 drives the placement tray 302 and the infusion bottle to rise, so that the medicine extraction tube 304 extends into the infusion bottle;
[0062] The docking electric push rod 316 operates to drive the two arc-shaped frames 317 to approach each other until the two arc-shaped frames 317 are docked. At this time, the arc-shaped frames 317 are located outside the lower liquid box 306, the liquid distribution pipe 308, and the upper liquid box 310. Medical staff place the syringe 220 inside the fixing frame 217, and then use the fixing groove 219 to put two annular rubber bands 221 on both ends of the syringe 220 to firmly fix the syringe 220 inside the fixing frame 217. Then, the pressing handle of the syringe 220 is fixed between the tightening clip 227 and the pushing piece 224 by rotating the tightening bolt 226;
[0063] Start the medicine extraction pump 303 and the heating electric hot plate 318. Under the guiding action of the medicine extraction pump 303, the liquid medicine inside the infusion bottle flows through the medicine extraction pipe 304, the medicine extraction pump 303, and the medicine outlet pipe 305 in sequence and enters the lower liquid box 306, and then flows through the liquid distribution pipe 308 into the upper liquid box 310. When the liquid medicine flows through the liquid distribution pipe 308, the liquid distribution pipe 308 increases the heat conduction area of the liquid medicine, and the heat generated by the heating electric hot plate 318 can quickly heat the liquid medicine to make the anesthetic liquid medicine reach the appropriate temperature required by the human body. Remove the sealing plug 312 from the liquid extraction hole 311, and insert the needle of the syringe 220 into the liquid extraction hole 311. As the first operation method, at this time, the quantitative medicine pipe 314 is not connected to the liquid medicine switch one-way joint 327. Medical staff then extract the heated liquid medicine. After the liquid medicine is heated to the appropriate temperature required by the human body, it can reduce the discomfort of the patient during subsequent injection of the liquid medicine. By rotating the lower connection plate 307 and the upper connection plate 309, the liquid distribution pipe 308 can be quickly disassembled and assembled, and the replacement is convenient;
[0064] The infusion bottle can be used to prepare anesthetic liquid medicine for multiple people. One preparation can be used for multiple people, and there is no need for doctors to prepare anesthetic liquid medicine multiple times, further reducing the labor intensity of manual work. When using the syringe 220 to extract the liquid medicine, separate the adsorption iron sheet 236 from the magnet sheet 232, remove the transparent rubber 233, hold the handle 214, and insert the needle of the syringe 220 into the liquid extraction hole 311. According to the needs of the patient, select the amount of liquid medicine to be extracted on the touch screen 228. Then, the pushing motor 225 is started. The pushing motor 225 drives the pushing screw rod 223 to rotate. Under the limiting action of the limiting sliding groove 216, the pushing motor 225 drives the limiting sliding block 222, the pushing piece 224, and the pressing handle of the syringe 220 to move. By controlling the operation of the pushing motor 225, accurate extraction of the liquid medicine is achieved, avoiding waste of the liquid medicine caused by medical staff extracting too much. During subsequent use, by swinging the electric push rod 322 to drive the placement plate 302 and the infusion bottle storing the liquid medicine to swing back and forth, the anesthetic agent and physiological saline are always in a good mixing state, ensuring the quality of the liquid medicine;
[0065] After the liquid medicine is extracted, the heat preservation electric hot plate 218 operates. The heat preservation electric hot plate 218 plays a role in heating and heat preservation. The heat preservation electric hot plate 218 emits heat to keep the liquid medicine inside the syringe 220 warm, and can always maintain the temperature of the liquid medicine during the transfer process of the syringe 220 and the subsequent injection process, greatly reducing the discomfort of the patient when injecting the liquid medicine. When injecting anesthetic liquid medicine, place the handle 214 between the two clamping plates 212, align the fixing hole 215 with the clamping block 213, hold the rotating head 211 and rotate the bidirectional screw 210. The bidirectional screw 210 drives the fixed slider 209 to approach each other inside the fixed slide rail 208, thereby driving the clamping plates 212 and the clamping blocks 213 to approach each other. The clamping block 213 is inserted into the fixing hole 215, and the clamping plate 212 can firmly fix the handle 214. After the fixing is completed, control the operation of the electric rail 202 according to the position of the patient's indwelling needle. The electric rail 202 drives the rotating base 203 and the syringe 220 to move, move the syringe 220 to the position of the indwelling needle, remove the fixing pin 207, and then rotate the rotating flat head 204 according to the position angle of the patient's indwelling needle. Control the angle of the syringe 220 needle by controlling the angle of the rotating flat head 204. Insert the fixing pin 207 into the corresponding docking male hole 205 and docking female hole 206, and then control the lifting cylinder 201 to drive the syringe 220 to lift and lower, so that the syringe 220 needle can be inserted into the medicine infusion port of the indwelling needle. The device can move flexibly according to the position where the anesthetic is administered, has a wide range of applications, and can be selected and matched according to hospital or on-site requirements;
[0066] When the anesthetic is continuously injected through the indwelling needle, select the injection volume and feeding speed on the touch screen 228 or operate the control button 237 to select the injection volume. The pushing motor 225 is started. The pushing motor 225 drives the pushing piece 224 to move. The device controls the feeding volume and feeding speed of the liquid medicine according to the requirements, eliminating the need for an anesthesiologist to always hold the syringe 220 to supplement the anesthetic, greatly reducing the labor intensity of the anesthesiologist, and through controlling the operation of the pushing motor 225, the feeding volume and feeding speed of the anesthetic can be controlled more precisely, and the anesthetic effect is better;
[0067] When intramuscularly injecting a patient, the positioning suction cup 235 is adsorbed on the patient's skin surface. The transparent rubber 233 can observe the position of the needle, enabling rapid needle positioning. During injection, apply pressure to the extruded transparent rubber 233. The transparent rubber 233 and the return spring 234 are compressed, and the needle is inserted into the patient's body. After the injection is completed, remove the pressure and the return spring 234 rebounds, and the needle is withdrawn from the patient's body, making the injection more convenient;
[0068] A liquid medicine switch one-way joint 327 is connected to the top of the syringe 220. Three control buttons 237 are arranged on the top of the medicine extraction pump 303. The three control buttons 237 respectively control the liquid medicine delivery volume of 5 ml, 10 ml and 15 ml of anesthetic. The quantitative medicine tube 314 can be connected to the liquid medicine switch one-way joint 327 at the bottom of the syringe 220. When anesthetic needs to be injected at multiple positions of multiple people, the quantitative medicine tube 314 is directly connected to the syringe 220 through the liquid medicine switch one-way joint 327. By pressing the control button 237, the medicine extraction pump 303 is passively controlled by the control button 237, and can directly deliver the anesthetic liquid medicine inside the infusion bottle to the inside of the syringe 220 in a quantitative manner. The pushing motor 225 moves back and forth to provide a medicine inlet space for the anesthetic liquid medicine and discharge the excess air from the needle hole, without the need to draw the liquid medicine back and forth for anesthetic injection, reducing the manual labor intensity, and as another operation mode, even as the main operation mode;
[0069] And when a doctor needs to go out for medical treatment in an ambulance, the doctor can move alone by holding the handle 214. The medicine can be prepared in advance in the ambulance. After the syringe 220 extracts the liquid medicine, the heat preservation electric hot plate 218 is started in advance. The heat preservation electric hot plate 218 emits heat to heat and keep warm the liquid medicine inside the syringe 220. When the doctor arrives at the scene, the patient can be quickly anesthetized. It has a wide range of applications and is convenient and fast. Among them, according to requirements, the control button 237 can be installed on the top of the medicine extraction pump 303 for two-way control.
