Nasal cavity medicine applying device used after nasal polypectomy

Abstract

The invention discloses a nasal cavity medicine applying device used after nasal polypectomy, and relates to the technical field of medical equipment. The nasal cavity medicine applying device used after nasal polypectomy comprises a sleeve pipe, wherein a piston is in sliding connection to the inner part of the sleeve pipe; an extruding rod is fixedly mounted at the right end of the piston; a spring is arranged on the periphery of the extruding rod in a sleeving manner; an air inlet is fixedly mounted at the left end of the sleeve pipe; a material collecting pipe is fixedly connected to the center of the left end of the sleeve pipe through an air pipe; and one-way valves are respectively and fixedly mounted in the air inlet and the air pipe. According to the nasal cavity medicine applyingdevice used after nasal polypectomy disclosed by the invention, in the medicine applying process, the material transporting pipe can be supported and limited, so that the material transporting pipe is conveniently aligned to a wound and performs applying, the wound is not liable to impact because of shaking of hands, and the operation difficulty is reduced; and before applying medicines, mucus atthe wound can be blown away, so that the contact between liquid medicines and the wound is facilitated, and the effect of the medicines is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nasal medicine application device after nasal polypectomy. Background technique [0002] Nasal polyps are proliferative tissue groups protruding from the nasal cavity or sinus mucosa surface. Nasal obstruction or increased nasal secretions are common manifestations, accompanied by facial pain or swelling, and hyposmia or loss. It is a common nasal disease , occurs in adults, rarely occurs in children, can be solitary or multiple, more common in the maxillary sinus, ethmoid sinus, middle meatus, middle turbinate, etc., and nasal polypectomy is the only way to completely treat nasal polyps In the best way, in order to avoid postoperative wound infection and speed up wound healing, it is necessary to regularly apply medicine to the nasal cavity. [0003] And because the wound of nasal polypectomy is located deep in the nasal cavity, and the position is different for dif...

Problems solved by technology

[0003] And because the wound of nasal polypectomy is located deep in the nasal cavity, and the position is different for different patients, it is necessary to use auxiliary devices. The traditional medicine feeding device does not have any support and assistance in the process of extending into the patient's nasal cavity. Therefore, in the process of applying medicine, the hands are prone to shake, and the medicine cannot be well aligned with the wound, which is not easy to apply, and it is easy to collide with the wound. However, the spraying method of applying medicine can be applied in the The effect of applying medicine can be achieved without contact with the wound, but it is easy to cause irritation to the patient's nasal cavity and cause uncomfortable reactions, and mucus is attached to the surface of the deep nasal cavity. When applying medicine, the medicine often cannot directly contact with the wound , reducing the effect of the drug
