Embodiment Construction

[0018] The quantitative nasal cavity spray device mainly solves the problem of each quantitative spraying dose of patients in different body positions.

[0019] The quantitative nasal cavity spray device comprises a micropump, a battery box, a control panel, a liquid medicine bottle, a suction pipe, a liquid outlet pipe, a spray head, a spray head connection ring, a medicine bottle connection port, and a handle.

[0020] In order to adapt to patients in different positions and ensure the effect of spraying, the nozzles adopt two types: straight nozzles and curved nozzles. The spray head includes a nozzle, a spray head connecting ring and a spray pipe. The spray pipe adopts a straight pipe or a curved pipe, and nozzles and nozzle connecting rings are respectively arranged at two ends of the spray pipe; the nozzles are hollow conical, and the conical nozzles can be in contact with the nasal cavity to prevent the medicinal liquid from flowing out. A plurality of small holes comm...

Abstract

According to clinical needs, in combination with existing technical measures, the invention designs a quantitative nasal cavity spraying device. The device can quantitatively spray the dosage of a vasoconstrictor and uniformly spray the vasoconstrictor on the surface of nasal mucosa. The quantitative nasal cavity spraying device comprises a micro pump, a battery box, a control panel, a liquid medicine bottle, a liquid suction pipe, a liquid outlet pipe, a spray head, a spray head connecting ring, a medicine bottle connecting opening and a handle. The spray head is divided into a bent spray head and a straight spray head, and a plurality of small holes are designed in the spray head. The micro pump is an ultra-small micro direct-current liquid pump. A display screen displays single injection dosage and total injection dosage.

Description

technical field [0001] The invention relates to a medical appliance, more specifically a quantitative nasal cavity spray device. Background technique [0002] In clinical anesthesia work, some patients need to receive general anesthesia through nasal endotracheal intubation, such as patients with long-term indwelling endotracheal tube after surgery, patients with oral and frontal facial surgery, patients with head and cervical spine surgery, limited mouth opening and poor cervical spine mobility Airway patients and patients with loose teeth. Nasal endotracheal intubation can improve patient comfort and satisfaction, reduce the cervical spine required for oral intubation, reduce damage to patients with loose teeth, and meet the needs of oral-frontal surgery. However, nasal endotracheal intubation also has certain disadvantages, such as: it may damage the nasal mucosa, cause nasal bleeding, make intubation difficult or cause aspiration, and in severe cases, electrocoagulation...
