Electric nasal cavity sampling and spraying device

Abstract

The invention discloses an electric nasal cavity sampling and spraying device which comprises a flushing fluid container, an upper cover, an electric control panel, a water pressing pipe and a water diversion pipe. The upper cover is detachably connected to an opening of the flushing fluid container. The upper portion of the upper cover is provided with a conical liquid outlet. The liquid outlet is connected with the water diversion pipe with the lower portion extending into the flushing fluid container. The electric control panel is connected to the inner side of the upper cover in a sealed waterproof mode. The electric control panel comprises a battery, a driving pump, a control unit and a switch assembly. The output end of the driving pump is connected with a water pressing pipe with the lower portion extending into the flushing fluid container. A charging port of the battery and a control button of the switch assembly are fixed to a slot formed in the upper cover in advance. The upper cover is provided with an inner cover for protecting the electric control panel. The inner cover is stuck to the upper cover in an interference fit mode. According to the electric nasal cavity sampling and spraying device, the output air pressure of the driving pump is electrically controlled, flushing fluid is pressed out by means of the pressure difference to flush the nasal cavity of a patient, and a virus sample flows out of the nasal cavity on the other side under the circulated flushing. Flushing is carried out through the flushing fluid, the patient feels more moist, more comfortable and moderate and has no drying or stimulation feeling, and the nasal mucosa is not damaged.

Description

Technical field [0001] The invention relates to a medical auxiliary device, in particular to an electric nasal cavity sampling and drug delivery device. Background technique [0002] Transmission through the respiratory tract is one of the main transmission routes of infectious diseases. Including SARS, bird flu, influenza A and other diseases that seriously endanger public health. Viruses, bacteria or other microorganisms transmitted through the respiratory tract are mostly excreted through respiratory secretions, transmitted through oral fluids, sneezing, contact, and transmitted through air droplets. The peak of infection is in autumn and winter and early spring. The droplets carrying pathogenic microorganisms adhere to the mucous membrane of the nasal cavity and then infect the patient. The detection of pathogens in the human nasal cavity or respiratory tract has important clinical significance. These tests require laboratory methods to sample and extract nasal secretions ...

AI Technical Summary

Problems solved by technology

3. After sampling, the virus sample will be trapped inside the fiber structure of the cotton swab sampling head, which is difficult to release and has a small collection ratio, so sometimes multiple sampling is required to reach the test volume

4. Because the epidermis of the nasal cavity is relatively weak, after the cotton swab is inserted into the nasal cavity, mechanical wiping will irritate the nasal mucosa. Improper force control will easily damage the nasal mucosa and cause bleeding

5. The quality of cotton swabs is uneven, improper operation may fall off, resulting in aspiration, and the risk of sampling is high

However, many nasal sprays are difficult to accurately reach the ideal site
