Oral and throat drug delivery device

Abstract

The invention discloses a drug feeding device for an oral laryngeal part, which comprises a drug feeding catheter and a drug storage bottle connected with the drug feeding catheter; the front end of the drug feeding catheter is provided with a drug nozzle, and the outside end of the drug feeding catheter is provided with a piston push rod; the drug nozzle is connected to the inside end of the drug feeding catheter through a rotating shaft and a control hole is arranged in the side wall of the drug feeding catheter; a pull cable is arranged in the control hole, one end of the pull cable is fixed in the middle of the side face of the drug nozzle; a reset spring is arranged between the side face of the drug nozzle and the drug feeding catheter, and the reset spring and the pull cable are arranged on a symmetrical side face of the drug nozzle; the outside end of the drug feeding catheter is provided with a rotary supporting base, and a winding shaft is arranged on the rotary supporting base. The drug feeding device is reasonable in structure setting and convenient to operate; the drug nozzle position is adjusted as required; meanwhile, the drug spraying amount can also be controlled; therefore, the application range is greatly improved, the using stability is good and the practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of instruments, and in particular relates to an oral and laryngeal drug delivery device. Background technique [0002] In the treatment of the oral cavity and throat, it is necessary to apply the medicine. In the traditional technology, the medicine is mainly inserted into the corresponding position of the oral cavity through the telescopic forceps to complete the medicine. Although the medicine can be applied, the operation is complicated and it is inconvenient to adjust the medicine. The amount is controlled, and the position cannot be effectively adjusted at the same time, so the applicability and practicability are limited. Contents of the invention [0003] The object of the present invention is to provide a drug delivery device for oral cavity and throat with reasonable structure and good stability in use. [0004] The technical solution for realizing the purpose of the present invention is a drug d...
