When medical staff needs to carry out intramuscular injection to a patient, the medical staff uses the device to extract the medicine at the moment, the staff submerges the needle 102 below the liquid level of the medicine to be extracted at the moment, then the staff pulls the push tube 105, the push tube 105 drives the second piston 104 to slide outwards along the inner wall of the injection cylinder 101, until the second piston 104 contacts with the limiting block 109, the second piston 104 drives the communicating pipe 107 to slide outwards along the injection cylinder 101 synchronously, the communicating pipe 107 drives the first piston 103 to slide outwards along the inner wall of the injection cylinder 101 synchronously, and the first piston 103 slides outwards along the injection cylinder 101 to extract the medicine to be extracted, so that the medicine extraction is completed.
After the medicine is completely extracted, the staff wipes the alcohol at the injection position of the patient for sterilization, then the staff inserts the needle 102 into the muscle of the patient, then the staff starts to push the push tube 105, at this time, the push tube 105 drives the second piston 104 to slide inwards along the injection cylinder 101, the communicating tube 107 slides along the second piston 104, and simultaneously compresses the first return spring 108, after the second piston 104 slides along the inside of the injection cylinder 101 until four re-compression holes 202 of the annular array on the second piston are butted with the corresponding plugging shafts 201, at this time, a closed cavity is formed between the first piston 103, the second piston 104 and the injection cylinder 101, the staff pushes the push tube 105 again to slide along the inner wall of the injection cylinder 101, the push tube 105 drives the second piston 104 to squeeze the gas in the closed cavity, and after the pressure of the gas in the closed cavity between the first piston 103, the second piston 104 and the injection cylinder 101 is higher than the pressure of the medicine, at this time, the gas in the closed cavity pushes the first piston 103 to squeeze the medicine along 102 into the body tissues of the patient until the medicine injection is completed, and then the needle 102 is pulled out, and the needle 102 is completely injected.
In the above process, after the sealed cavity is formed between the first piston 103, the second piston 104 and the syringe 101, as the second piston 104 continues to slide along the syringe 101, at this time, the gas pressure in the sealed cavity between the first piston 103 and the second piston 104 gradually increases, at this time, the gas in the sealed cavity between the first piston 103, the second piston 104 and the syringe 101 pushes the four third pistons 301 of the annular array, the four third pistons 301 of the annular array slide along the first piston 103, the four third pistons 301 of the annular array drive the first extrusion block 302 to slide synchronously along the first piston 103, and simultaneously compress the four second return springs 303 of the annular array, the first extrusion block 302 slides along the first piston 103 to extrude the sealing ring 110, the sealing ring 110 is outwards supported by the extrusion force of the first extrusion block 302, the sealing ring 110 is outwards supported to increase the fitting degree with the inner wall of the syringe 101, so as to avoid leakage of the medicine when the sealing ring 110 slides along the syringe 101 during the injection of the medicine.
During the injection of the medicine by the staff, the pushing force pushing the push tube 105 is unstable due to different staff levels, when the pushing force pushing the push tube 105 is increased, the speed of injecting the medicine is increased, the medicine impacts cells, the damage to the cells is caused, and the nerve endings are stimulated to cause pain, therefore, after the first piston 103 pushes the medicine to start injection, when the pushing force of the staff is increased, the pushing force received by the push tube 105 is increased, the push tube 105 drives the second piston 104 to slide along the inner wall of the injection cylinder 101, the second piston 104 slides along the inner wall of the injection cylinder 101 to squeeze the gas in the closed cavity, the gas in the closed cavity is extruded by the second piston 104, the volume is reduced, the pressure is increased, the increase of the pressure of the gas in the closed cavity breaks through the plugging of the hard sheet film in the four pressure relief holes 106 of the annular array, at the moment, the gas in the closed cavity enters the communicating pipe 107 through the four pressure relief holes 106 of the annular array until the pressure of the gas in the closed cavity between the first piston 103, the second piston 104 and the injection cylinder 101 is restored to a stable state, and the pressure in the closed cavity is stabilized through the partition of the thrust between the first piston 103, the second piston 104 and the injection cylinder 101, so that the pressure in the closed cavity is stabilized through the four pressure relief holes 106 of the annular array, the first piston 103 is ensured to push the medicine at a constant speed for injection, the condition that the injection speed of the medicine is too high, the cells at the injection position are damaged is avoided, and the patient feels pain.
After the gas in the closed cavity breaks through the blocking of the hard film and enters the communicating pipe 107, the gas is discharged outwards along the communicating pipe 107, the gas flows along the communicating pipe 107 and contacts with the first fan blades 402 of the annular array in the rotating shell 401, the gas pushes the first fan blades 402 of the annular array to rotate, the first fan blades 402 of the annular array rotate to drive the rotating shell 401 to synchronously rotate, the rotating shell 401 rotates to drive the second fan blades 403 of the annular array to synchronously rotate, the second fan blades 403 rotate to remind a worker that the thrust is overlarge, at the moment, the worker reduces the thrust to the push pipe 105, the first piston 103 is ensured to push the medicine at a uniform speed, the phenomenon that the medicine injection speed is too fast to form impact to cells is avoided, and the patient feels painful is caused.
