[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. It is equipped with a multi-angle precision injection assembly. The syringe is placed inside the fixed frame, and then two circular rubber bands are put on both ends of the syringe using the fixed groove, which is easy to install;

[0024] By rotating the bidirectional screw, the fixed sliders are driven to approach each other inside the fixed slide rail, the clamping block is embedded in the fixed hole, and the clamping plate firmly fixes the handle. After the fixation is completed, the syringe is driven to move by controlling the electric rail, and the fixing pin is inserted into the corresponding docking male hole and docking female hole. The angle of the syringe needle is controlled by controlling the angle of the rotating flat head. The syringe needle can be inserted into the drug delivery port of the indwelling needle, and the syringe is driven to rise and fall with the lifting cylinder. The device can be flexibly moved according to the location of the anesthetic injection, and has a wide range of applications.

[0025] When continuous injection is made through the indwelling needle, the push motor drives the push plate to move, and the device can control the feeding amount and feeding speed of the liquid medicine according to the needs, so that the anesthesiologist does not need to hold the syringe to replenish the anesthetic all the time, which greatly reduces the labor intensity of the anesthesiologist. In addition, by controlling the operation of the push motor, the feeding amount and feeding speed of the anesthetic can be controlled more accurately, and the anesthesia effect is better.

[0026] When injecting the patient's muscle, the positioning suction cup is attached to the patient's skin surface. The transparent rubber can be used to observe the position of the needle and quickly locate the needle. When injecting, pressure is applied to squeeze the 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 quick.

[0027] When the doctor needs to go out for medical treatment by ambulance, the doctor can move by holding the handle alone, and the medicine can be prepared in advance in the ambulance. After the syringe draws the medicine liquid, the heat preservation electric heating plate is started in advance. The heat preservation electric heating plate emits heat to heat and keep the medicine liquid inside the syringe. When the doctor arrives at the scene, the patient can be anesthetized quickly. It has a wide range of applications and is convenient and fast.

[0028] 2. A liquid medicine mixing and heating component is provided. When preparing medicine, the mixed infusion bottle is placed on the top of the placement plate. The infusion bottle is fixed in the center by controlling the docking electric push rod to drive the clamping arc plates to move closer to each other. 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 placement plate and the infusion bottle to swing back and forth, so that the high-concentration anesthetic agent and the physiological saline are fully mixed. There is no need to manually shake the infusion bottle for mixing, which reduces the labor intensity. The infusion bottle can prepare anesthetic liquid for multiple people, and it can be used for multiple people at one time. There is no need for doctors to prepare anesthetic liquid multiple times, which further reduces the labor intensity.

[0029] By starting the drug extraction pump and the heating electric heating plate, the drug liquid in the infusion bottle flows through the drug extraction tube, the drug extraction pump and the drug outlet tube in sequence into the lower liquid box, and then flows through the liquid separation tube into the upper liquid box. When the drug liquid flows through the liquid separation tube, the liquid separation tube increases the heat conduction area of ​​the drug liquid. The heat generated by the heating electric heating plate can quickly heat the drug liquid, so that the anesthetic drug liquid reaches the appropriate temperature required by the human body. The medical staff then extracts the heated drug liquid, which can reduce the patient's discomfort during the subsequent injection of the drug liquid.

[0030] The three control buttons control the delivery volume of 5ml, 10ml and 15ml anesthetic liquid respectively. When anesthetic drugs need to be injected into multiple parts of a person, the quantitative drug tube is directly connected to the syringe. By pressing the control button, the drug pump can directly deliver the anesthetic liquid in the infusion bottle to the syringe in a quantitative manner. There is no need to draw the liquid back and forth for anesthetic injection, which reduces the intensity of manual labor.

[0031] To sum up, in the drug liquid mixing and heating component, when the drug liquid flows through the dispensing tube, the dispensing tube diverts the drug liquid to increase the heat conduction area of ​​the drug liquid, and quickly heats the drug liquid to the required temperature. In the drug liquid multi-angle precision injection component, the heat-insulating electric heating plate can heat and keep the drug liquid inside the syringe warm, and can always maintain the temperature of the drug liquid during the transfer of the syringe and the subsequent injection process. When injecting the drug liquid, the patient's discomfort is minimized to the greatest extent. There are two operating modes, which are suitable for use in different situations. The operation is more comprehensive and reasonable, and suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] A lifting electric push rod 319 is installed at the bottom of the inner side of the dustproof box 301, and the output end of the lifting electric push rod 319 is connected to an assembly plate 320. A swing gear 321 is rotatably installed in the middle of the top of the assembly plate 320. A swing electric push rod 322 is installed on the top of the assembly plate 320 on one side of the swing gear 321. The output end of the swing electric push rod 322 is connected to a swing rack 323, and the swing rack 323 is meshed with the swing gear 321. The top of the swing gear 321 is connected to the bottom of the placement plate 302. In the middle, clamping electric push rods 324 are installed on both sides of the top of the placement plate 302, and the output end of the clamping electric push rods 324 is connected to a clamping arc plate 325. The infusion bottle containing anesthetic agents is placed between the two clamping arc plates 325. The clamping electric push rods 324 are controlled to drive the clamping arc plates 325 to approach each other so that the infusion bottle can be fixed in the center. A rubber pad 326 is bonded to the top 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 drug extraction pump 303, the docking electric push rod 316, the heating electric plate 318, the lifting electric push rod 319, the swinging 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 drug extraction pump 303, the docking electric push rod 316, the heating electric plate 318, the lifting electric push rod 319, the swinging 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. The above electrical components can be controlled by controlling the external controller.

[0061] The working principle and use process of the present invention are as follows: when in use, high-concentration anesthetic agent and physiological saline are delivered to the inside of the infusion bottle according to the required proportion, the infusion bottle containing the mixture is placed on the top of the placement tray 302, and the docking electric push rod 316 is started. The docking electric push rod 316 drives the clamping arc plate 325 to approach each other to fix the infusion bottle in the center. After the infusion bottle is fixed, the swinging electric push rod 322 is started. The swinging electric push rod 322 drives the swinging rack 323 to move back and forth, and then drives the swinging gear 321, the placement tray 302 and the infusion bottle to swing back and forth. The back and forth swinging of the infusion bottle fully mixes the high-concentration anesthetic agent and physiological saline in the bottle to form a diluted required anesthetic solution. There is no need to manually shake the infusion bottle for mixing, which reduces the intensity of manual labor and achieves a better effect of mixing the liquid medicine. After the full mixing is completed, the lifting electric push rod 319 is started. The lifting electric push rod 319 drives the placement tray 302 and the infusion bottle to rise, so that the drug extraction tube 304 extends into the infusion bottle.

[0062] The operation of the docking electric push rod 316 drives the two arc frames 317 to approach each other until the two arc frames 317 are connected to each other. At this time, the arc frame 317 is located outside the lower liquid box 306, the dispensing tube 308 and the upper liquid box 310. The medical staff places the syringe 220 inside the fixing frame 217, and then uses the fixing groove 219 to cover the two annular rubber bands 221 at both ends of the syringe 220 to firmly fix the syringe 220 inside the fixing frame 217, and then fixes the syringe 220 between the tightening clip 227 and the pushing piece 224 by rotating the tightening bolt 226;

[0063] Start the drug pump 303 and the heating plate 318. Under the guidance of the drug pump 303, the drug liquid in the infusion bottle flows through the drug extraction tube 304, the drug pump 303 and the drug outlet tube 305 in sequence to enter the lower liquid box 306, and then flows through the liquid separation tube 308 to enter the upper liquid box 310. When the drug liquid flows through the liquid separation tube 308, the liquid separation tube 308 increases the heat conduction area of ​​the drug liquid. The heat generated by the heating plate 318 can quickly heat the drug liquid, so that the anesthetic liquid reaches the required temperature of the human body. When the temperature is appropriate, the sealing plug 312 is removed from the liquid extraction hole 311, and the needle of the syringe 220 is inserted into the liquid extraction hole 311 as the first operation mode. At this time, the quantitative medicine tube 314 is not connected to the one-way joint 327 of the medicine switch. The medical staff then extracts the heated medicine. After the medicine is heated to the appropriate temperature required by the human body, the discomfort of the patient can be alleviated during the subsequent injection of the medicine. The dispensing tube 308 can be quickly disassembled and assembled by rotating the lower receiving plate 307 and the upper receiving plate 309, and the replacement is convenient;

[0064] The infusion bottle can be used to prepare anesthetic liquid for multiple people. It can be used for multiple people once prepared. There is no need for doctors to prepare anesthetic liquid multiple times, which further reduces the intensity of manual labor. When using the syringe 220 to extract the liquid, separate the adsorption iron sheet 236 from the magnet sheet 232, remove the transparent rubber 233, hold the handle 214, insert the needle of the syringe 220 into the liquid extraction hole 311, select the amount of liquid to be extracted on the touch screen 228 according to the patient's needs, and then start the push motor 225, which drives the push motor 225 to drive ... The push screw 223 rotates, and under the limiting action of the limiting slide groove 216, the push motor 225 drives the limiting slider 222, the push piece 224 and the syringe 220 to move by hand. By controlling the operation of the push motor 225, the accurate extraction of the liquid medicine is achieved, which avoids the waste of liquid medicine caused by excessive extraction by medical staff. In the subsequent use process, the placing plate 302 and the infusion bottle storing the liquid medicine are driven to swing back and forth by swinging the electric push rod 322, so that the anesthetic agent and the physiological saline are always in a good mixed state, ensuring the quality of the liquid medicine;

[0065] After the drug solution is extracted, the heat preservation electric heating plate 218 is operated, and the heat preservation electric heating plate 218 plays a role of heating and heat preservation. The heat preservation electric heating plate 218 emits heat to keep the drug solution inside the syringe 220 warm. During the transfer process of the syringe 220 and the subsequent injection process, the temperature of the drug solution can be kept at all times. When injecting the drug solution, the patient's discomfort is minimized to the greatest extent. When injecting the anesthetic solution, the handle 214 is placed between the two clamping plates 212, and the fixing hole 215 is aligned with the clamping block 213. The handheld rotating head 211 rotates the bidirectional screw 210, and the bidirectional screw 210 drives the fixed slider 209 to approach each other inside the fixed slide rail 208, thereby driving the clamping plate 212 and the clamping block 213 to approach each other, and the clamping block 213 is embedded in the fixing hole 215. The clamping plate 212 is close to the handle 21 4. After the fixation is completed, the electric rail 202 is controlled to operate 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, and the syringe 220 is moved to the position of the indwelling needle. The fixing pin 207 is removed, and then the rotating flat head 204 is rotated according to the position angle of the patient's indwelling needle. The angle of the syringe 220 needle is controlled by controlling the angle of the rotating flat head 204, and the fixing pin 207 is inserted into the corresponding docking male hole 205 and the docking female hole 206. Then the lifting cylinder 201 is controlled to drive the syringe 220 to move up and down, so that the syringe 220 needle can be inserted into the drug delivery port of the indwelling needle. The device can be flexibly moved according to the position of the anesthetic, has a wide range of applications, and can be selected according to the requirements of the hospital or the site;

[0066] When the anesthetic is continuously injected through the indwelling needle, the desired injection amount and feeding speed are selected on the touch screen 228 or the injection amount is selected by operating the control button 237, and the push motor 225 is started, and the push motor 225 drives the push sheet 224 to move. The device controls the feeding amount and feeding speed of the liquid medicine as required, and the anesthesiologist does not need to hold the syringe 220 all the time to replenish the anesthetic, which greatly reduces the labor intensity of the anesthesiologist. In addition, by controlling the operation of the push motor 225, the feeding amount and feeding speed of the anesthetic can be more accurately controlled, and the anesthetic effect is better.

[0067] When injecting into the patient's muscle, the positioning suction cup 235 is attached to the patient's skin surface, and the transparent rubber 233 can be used to observe the position of the needle and quickly locate the needle. When injecting, pressure is applied to squeeze the transparent rubber 233, and 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, the pressure is removed, the return spring 234 rebounds, and the needle is removed from the patient's body, making the injection more convenient and quick.

[0068] A liquid medicine switch one-way joint 327 is connected to the top of the syringe 220, and three control buttons 237 are arranged on the top of the drug pump 303. The three control buttons 237 respectively control the delivery volume of 5ml, 10ml and 15ml of anesthetic liquid. The quantitative drug tube 314 can be connected to the liquid medicine switch one-way joint 327 at the bottom of the syringe 220. When it is necessary to inject anesthetics into multiple locations of multiple people, the quantitative drug 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 drug pump 303 is passively controlled by the control button 237, and the anesthetic liquid in the infusion bottle can be directly and quantitatively delivered to the inside of the syringe 220. The push motor 225 returns to its original position to provide a space for the anesthetic liquid to enter the medicine, and the excess air is discharged from the needle hole. There is no need to extract the liquid back and forth for anesthetic injection, which reduces the labor intensity of manual labor. It is another operation mode, or even the main operation mode.

[0069] When the doctor needs to go out for medical treatment by ambulance, the doctor can move by holding the handle 214 alone, and the medicine can be prepared in advance in the ambulance. After the syringe 220 draws the medicine liquid, the heat preservation heating plate 218 is started in advance. The heat preservation heating plate 218 emits heat to heat and keep the medicine liquid inside the syringe 220. When the doctor arrives at the scene, the patient can be anesthetized quickly. The application range is wide and the operation is convenient and fast. The control button 237 can be installed on the top of the medicine pump 303 according to requirements for two-way control.
