When the spraying device is used, the outlet end of the double-hole pipe 5 is aligned with a focus part needing spraying, meanwhile, a medical staff holds the frame 1, simultaneously, the regulating valve 12 is opened to penetrate through the gas pipe 10, and part of compressed air stored in the pressure tank 8 is sprayed out of the conical pipe 4 through the gas pipe 10 and the negative pressure pipe 9; because the conical tube 4 has the characteristics of large inlet and small outlet, when air flows at high speed, negative pressure is formed in the powder tank 3, and meanwhile, the other part of compressed air output from the pressure tank 8 enters the powder tank 3 through the blowing branch tube, so that accumulated powder is blown up and distributed in the powder tank 3 in a suspension state; the negative pressure formed in the conical tube 4 pumps out the powder in a suspension state in the powder tank 3 through the pumping tube, and then enters the focus through the double-hole tube 5; meanwhile, the air output by the blowing pipe 13 can continuously supplement the air pumped by the powder pumping pipe 11 in the powder tank 3 to keep the air pressure in the powder tank 3 stable, so that a stable pressure difference is formed between the conical pipe 4 and the powder tank 3, and the continuous and stable output of the powder is realized;
simultaneously, medical staff pushes the pushing piston 14 to push the liquid medicine in the liquid storage tank 2 into the double-hole pipe 5, and finally, the liquid medicine is conveyed to a focus part through the double-hole pipe 5 and mixed with the medicinal powder in the focus part, so that synchronous conveying of the liquid medicine and the medicinal powder is realized;
compared with the prior art, the automatic medicine powder conveying device has the advantages that negative pressure is formed through high-speed air flow, so that automatic medicine powder conveying is realized, the structure is simple, the stability is high, and as the output speed of medicine powder can be controlled through the regulating valve 12, medical staff does not need to pay excessive attention to medicine powder conveying, the operation method is simplified, and the stability of medicine liquid conveying is improved;
meanwhile, stable negative pressure for sucking materials can be formed by controlling the flow speed of the air flow, so that continuous and stable output of the medicinal powder is realized, the medicinal powder and the medicinal liquid are always in an optimal proportioning interval, the mixing effect is improved, and the treatment effect is improved;
in the technical scheme of the application, the medicine powder tank 3 is in a closed state, so that no matter what angle a medical staff holds the device, medicine powder can not leak, the medical staff can use the device in a more comfortable holding mode, the operability is stronger, and the user experience is improved;
compared with the prior art, the medicine injection device has the advantages that the pushing piston 14 can be operated after the regulating valve 12 is opened to realize medicine liquid injection, namely medicine liquid is synchronously conveyed to a focus in the process of spraying medicine powder on the focus, so that the time difference between medicine powder and medicine liquid injection is shortened to the greatest extent, a large amount of medicine powder is prevented from accumulating at the focus, and the treatment quality is ensured; the purpose can be achieved through continuous high-pressure air, the reliability is good, the stability is high, and meanwhile an electronic control component is not required to be additionally arranged.
