Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and more particularly to a drug powder spraying device with controllable drug output. Background Art

[0002] "Drug powdering" is a relatively broad concept, which covers a variety of different drug preparations and powdering methods.

[0003] When treating the wound of a patient, the staff needs to use a spraying device to spray medicine powder on the wound of the patient to achieve the effect of treating the wound. However, when the staff uses the spraying device to spray powder, it is difficult to reasonably control the spraying amount of the medicine according to the size of the wound. When too much medicine is sprayed, it will not only cause a waste of medicine, but also easily cause excessive accumulation of medicine powder, resulting in airtight wound and affecting recovery. When the amount of medicine powder sprayed is too little, the effective treatment effect cannot be achieved.

[0004] Therefore, the present invention provides a drug powder spraying device with controllable drug output, which helps workers to better control the spraying amount of drug powder. Summary of the invention

A control module 109 is also installed outside the medicine box 1. The data processing module 108 sends different signals to the control module 109 according to the size of the data transmitted by the electronic ruler 302. The control module 109 is used to control the opening and closing of the electronic valve 105. An image acquisition module 111 is installed at the position between the two rotating plates 301 at the lower end of the medicine box 1. The image acquisition module 111 acquires images of the wound part, and the image acquisition module 111 transmits the acquired image information to the data processing module 108;

[0043] A fan 110 is installed at a position outside the medicine box 1 relative to the transition chamber 103 , and the fan 110 blows air into the transition chamber 103 .

[0044] By adopting the above technical solution, when it is necessary to spray medicine powder, the position of the medicine spray port 106 is made to correspond to the patient's wound. At this time, the image acquisition module 111 can acquire images of the patient's skin surface, and the data processing module 108 immediately sends a signal to the control module 109, which controls the second electric push rod 303 to work, thereby driving the rotating plate 301 to rotate.

[0049] By adopting the above technical solution, the second electric push rod 303 can squeeze the rotating plate 301 when extended so that the two rotating plates 301 rotate at the same time. When the second electric push rod 303 contracts, it can drive the rotating plates 301 to rotate in the opposite direction. When the ends of the two rotating plates 301 are close to each other, the rubber pads 304 on the two rotating plates 301 will squeeze each other, so that the spray port 106 is sealed. When the two rotating plates 301 are unfolded, the pleated curtain 204 can be pulled to unfold the pleated curtain 204. After the pleated curtain 204 is unfolded, it can block the powder so that the powder can slide down along the rotating plate 301.

[0050] One end of the electronic ruler 302 is embedded in one end of the rotating plate 301 , and the pulled end of the electronic ruler 302 is fixedly connected to the other end of the rotating plate 301 .
