Technical Field
The invention relates to a medical appliance, in particular to a quantitative nasal cavity spraying device.
Background
In clinical anesthesia work, some patients need to take general anesthesia through a nasal endotracheal intubation, such as postoperative patients with long-term indwelling tracheal tubes, oral and frontal face surgery patients, head and cervical vertebra surgery patients, patients with difficult airway due to limited mouth opening and poor cervical vertebra mobility, and patients with loose teeth. The nasal endotracheal intubation can improve the comfort and satisfaction of patients, reduce the back elevation of cervical vertebra required by the operation of the oral intubation, reduce the damage to the patients with loose teeth and meet the needs of the oral frontal surgery. However, nasal endotracheal tubes also have certain disadvantages, such as: nasal mucosa may be damaged, resulting in nasal hemorrhage, difficult intubation or aspiration, and severe patients need intranasal endoscopic electrocoagulation hemostasis treatment.
The surface area of the nasal mucosa of the human body is about 150cm2The mucosa wall is thin, the capillary vessels are rich, and the medicine absorption is good. Clinically, before the tracheal catheter is inserted, a nasal vasoconstrictor is usually dropped or sprayed to constrict the blood vessels of the nasal mucosa. Sometimes, a cotton piece soaked with vasoconstrictor is plugged into the nasal cavity to play a role in contracting blood vessels of the nasal mucosa. A paper published in Anesthesiology 3.2000 reports a series of cases with severe cardiovascular side effects after intranasal administration of vasoactive drugs. One of the 4 year old children received an unidentified dose of phenylephrine nasal surface anesthesia resulting in severe hypertension and tachycardia that eventually led to death. Therefore, the regulation and control of the dosage of the vasoconstrictor in the nasal cavity are particularly important.
With the development of science and technology, micropumps are widely used in various industries from large to small, from alternating current to direct current, and with more and more varieties, types and functions, such as quantitative suction and high-speed (high-pressure) ejection. Micropumps, in particular ultra-small micropumps, are also used in a very wide range of applications in the field of medical and health, such as quantitative analysis in test instruments, electronic syringes for diabetics.

Detailed Description
The quantitative nasal cavity spraying device mainly solves the problem that the medicine quantity of the patients with different body positions is sprayed quantitatively every time.
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 connecting ring, a medicine bottle connecting port and a handle.
In order to adapt to patients with different body positions and ensure the spraying effect, the spray head adopts a straight spray head and a bent spray head. The spray head comprises a spray nozzle, a spray head connecting ring and a spray pipe. The spray pipe is a straight pipe or a bent pipe, and a spray nozzle and a spray head connecting ring are respectively arranged at two ends of the spray pipe; the nozzle is hollow conical, and the conical nozzle can contact with nasal cavity to prevent outflow of medicinal liquid. The cone is provided with a plurality of small holes communicated with the hollow pipe, and the entering liquid medicine sprays mist liquid medicine from the small holes.
