Abstract
Description
Technical Field
[0001] The invention relates to the technical field of vaccine injection, in particular to a vaccine continuous injection device. Background Art
[0002] Vaccines refer to biological products made from various pathogenic microorganisms for use in vaccination. Vaccines made from bacteria or spirochetes are also called vaccines. Vaccines are divided into two types: live vaccines and dead vaccines. Commonly used live vaccines include BCG, polio vaccine, measles vaccine, plague vaccine, etc. Commonly used dead vaccines include pertussis vaccine, typhoid vaccine, meningococcal vaccine, cholera vaccine, etc.
[0003] During vaccination, vaccines are generally injected through a syringe. However, when the number of people to be vaccinated is large, it is necessary to frequently transfer liquid to a new syringe, and multiple people are required to cooperate in the vaccination. In order to avoid frequent pipetting and improve work efficiency, some places use vaccine injection guns for continuous injections. However, these vaccine injection guns have a large holding volume.

Through the outer covering tube 401, the isolation sealing ring 402, the liquid pushing air inlet area 403, the needle pushing air inlet area 404, the warning air inlet area 405, the vaccine storage tube 406, the top The cover 407, the liquid pushing piston 408, the shift column 409, the rubber sealing cover 410, the liquid pushing air hole 411, the syringe barrel 412, the rubber sealing plug 413, the first shift ring 414, the second shift ring 415, the push needle air inlet hole 416, the push needle air exhaust hole 417, the push needle piston 418, the puncture needle 419 and the needle retracting spring 420 can integrate the original medicine bottle and the syringe when used, avoid frequent medication, and facilitate disposable use, reduce the risk of cross infection, and seal the inserted puncture needle 419 with the rubber sealing plug 413 to avoid easy leakage of the liquid medicine, and also facilitate the storage of the puncture needle 419 before and after injection, thereby improving safety.
[0033] Working principle: When loading, first insert the disposable needle storage and liquid storage mechanism into the interior of the storage tube 114 through the feed port 107, keep the rubber seal 413 facing the protective shell 101, and then start the stepper motor 111. The stepper motor 111 drives the support tube 112 to drive the connecting ring 113 to rotate and move the angle, so that the new storage tube 114 reaches the side of the feed port 107, and then insert the new disposable needle storage and liquid storage mechanism again, and then start the stepper motor 111 to load, and repeat this operation until all the storage tubes 114 are loaded. When unloading, start the stepper motor 111 to bring the disposable needle storage and liquid storage mechanism to be unloaded to the inner side of the feed port 107 corresponding to the discharge port 104, and then push the disposable needle storage and liquid storage mechanism from this feed port 107 to make it slide out of the discharge port 104; When in use, firstly connect the trachea connector 106 with the output pipe of the medical air pump, and then load the material. After loading, firstly energize the limit electromagnet 304 and the switch electromagnet 211 on the surface of the warning air guide hose 209. The limit electromagnet 304 is energized to attract the limit armature 307. When attracted, the pull slider 305 is driven to slide toward the limit electromagnet 304, and the pull slider 305 slides synchronously. The pull slider 305 pushes the gear hook 308 to close through the connecting rod 309. At this time, the gear hook 308 is closed. 08 forms a blockage at the end of the packaging tube 203, and then pulls the holding and pushing mechanism to make the material guide hose 109 straighten, and when the switch electromagnet 211 on the surface of the warning gas guide hose 209 is energized, the switch electromagnet 211 is energized to attract the switch armature 213, and the switch armature 213 releases the squeezing of the warning gas guide hose 209, and the warning gas guide hose 209 is unblocked, and then the medical air pump is started to pump high-pressure gas, and then the stepper motor 111 is started to store the disposable needle storage liquid mechanism When the outer tube 401 reaches the end of the position and is blocked by the stop hook 308, the outer tube 401 just passes the stop block 205, and the stop block 205 rebounds and forms a limit at the rear end of the outer tube 401 to prevent it from retreating. At the same time, after the outer tube 401 reaches the end of the position, the gas above the upper part communicates with the warning gas guide hose 209, and the gas enters the warning gas guide hose 209 from the pipeline connector 201, and then is discharged from the bottom end of the packaging tube 203. At this time, the medical staff feels the air flow from the bottom end of the packaging tube 203, indicating that the disposable needle storage mechanism is in place, and reminds the medical staff and the patient's body not to get close to the bottom end of the packaging tube 203, and then pushes the needle; When pushing the needle, firstly, the switch electromagnet 211 on the surface of the warning gas hose 209 is powered off, and the air closing spring 214 pushes the switch armature 213 to reset, thereby closing the warning gas hose 209, and then the switch electromagnet 211 on the surface of the push needle gas hose 208 is powered on, and the push needle gas hose 208 is turned on. At this time, the gas enters the push needle gas hose 208 from the pipeline connector 201, and then enters the needle storage cylinder 412 from the push needle air inlet area 404, and then squeezes the push needle piston 418 from the top. After being pressed, the push needle piston 418 slides downward, so that the push needle piston 418 below The air is discharged from the push needle exhaust hole 417, and the push needle piston 418 slides downward to squeeze the needle retracting spring 420 to shrink, and drive the puncture needle 419 to pierce the rubber seal 413 and extend from the bottom of the rubber seal 413 until the puncture needle 419 extends to the end of the position, and then the switch electromagnet 211 on the surface of the push needle air guide hose 208 is powered off, so that the push needle air guide hose 208 is closed. At this time, the top of the push liquid piston 408 is filled with gas, and the elastic force of the needle retracting spring 420 squeezes the push needle piston 418 to make the puncture needle 419 shrink a short distance and then maintain it stably; Then adjust the pumping strength of the medical air pump to ensure that the subsequent liquid pushing force is appropriate, then insert the puncture needle 419 into the designated part of the patient that has been disinfected, and then energize the switch electromagnet 211 on the surface of the liquid pushing gas guiding hose 207, so that the liquid pushing gas guiding hose 207 is turned on, and the gas enters the liquid pushing gas guiding hose 207 from the pipeline connector 201, and then enters the interior of the top cover 407 from the liquid pushing gas inlet area 403. After the gas enters the interior of the top cover 407, it will squeeze the liquid pushing piston 408 to slide down. The sliding of the liquid pushing piston 408 will squeeze the internal vaccine liquid into the puncture needle 419, and then enter the human body along the puncture needle 419 to complete the injection. After the injection is completed, the puncture needle 419 is pulled out and the bleeding is stopped; Then, the packaging tube 203 is aligned with the medical waste collection point, and then the limit electromagnet 304 is powered off. After the limit electromagnet 304 is powered off, the unloading tension spring 310 pulls the sliding block 305 to slide along the guide slide 301 away from the limit electromagnet 304, and the sliding block 305 drives the gear hook 308 to open through the connecting rod 309. The opened gear hook 308 releases the obstruction of the outer covering tube 401, and the gas pushes the disposable needle storage mechanism to discharge the packaging tube 203. During the discharge, the push needle air inlet 416 is connected to the air on the outer wall, and the two sides of the push needle piston 418 are under constant pressure. The needle retracting spring 420 pushes the push needle piston 418 to retract the puncture needle 419, and then the limit electromagnet 304 and the switch electromagnet 211 on the surface of the warning air guide hose 209 are energized again, so as to perform a new vaccine injection.
