Description

Micro-bubble ultrasonic wave bubble removal instrument for injector Technical Field The invention relates to the field of medical auxiliary instruments, in particular to an injector micro-bubble ultrasonic wave bubble removing instrument. Background In the field of medicine, the improvement of the absorption rate of medicine injection and the reduction of adverse reactions related to medicine injection are key problems needing to be continuously concerned in the process of medicine development, bubbles with different sizes can be generated in the process of medicine preparation, especially for microbubbles with diameters below 50um, the microbubbles shrink by themselves, the rising speed is slow, the negative charge is increased, and a large number of microbubbles in solution are difficult to effectively remove. Patients are self-equipped with injections at home, such as anticancer drugs injected by home, recombinant human growth hormone powder and the like, often because of insufficient mixing of the powder and injection water in the dispensing process or incorrect dispensing method, the drugs are insufficiently dissolved, a large number of bubbles with different sizes are generated, even if the patients stand for a few minutes, micro bubbles in the drugs cannot be effectively removed, the micro bubbles are injected into the patients along with the drugs, a series of consequences are generated that the drugs adhere to the bubble walls to cause low absorption rate and poor utilization rate of the drugs, unnecessary waste of the drugs to cause direct and indirect economic losses, and meanwhile, the bubbles themselves and the bubble walls carry the drugs which are insufficiently dissolved into human bodies and even directly threaten the life safety of the patients. There is concern that bubbles in the medicament, especially microscopic bubbles, are removed after the medicament is dispensed by the injector, and no effective method and corresponding technology exist at present, so the invention provides an ultrasonic bubble removing instrument applied to removing the bubbles in the injector. Disclosure of Invention Based on the problems, the invention aims to provide an ultrasonic bubble removal instrument for micro bubbles of an injector, which adopts the following technical scheme: the invention provides an ultrasonic bubble removal instrument for micro bubbles of an injector, which comprises: The top of the water tank is of an opening structure, and the bottom of the water tank is provided with a base; the ultrasonic device is arranged on the side wall of the water tank; The number of the piston fixtures is two, the two piston fixtures are arranged at the bottom of the water tank, and the two piston fixtures are matched to fix and clamp the injector. Preferably, the outer part of the water tank is provided with an environment-friendly plastic shell. Preferably, the number of the ultrasonic devices is two, and the ultrasonic devices are symmetrically arranged on the side wall of the water tank; the ultrasonic device comprises an ultrasonic transducer, the ultrasonic transducer is fixed on the wall of the water tank, and the radiation surface of the ultrasonic transducer is connected with a vibration expansion sheet arranged in the water tank. Preferably, the radiation surface of the ultrasonic transducer is provided with two vibration-amplifying sheets, and the two vibration-amplifying sheets form a semi-arc shape. Preferably, the piston fixer comprises two rotating shafts which are in power connection with the driving device, the rotating shafts are connected to the base in a sealing and rotating mode, and arc-shaped blades are arranged on the outer walls of the rotating shafts.
