Nasal passage irrigation catheter device

Abstract

The invention discloses a nasal passage irrigation catheter device comprising a catheter unit, a connecting unit, and an injection unit. The catheter unit comprises a catheter body and a plurality of holes formed in the catheter body. The catheter body has an open end and a closed end opposite to the open end. The connecting unit comprises a connecting part and a combination part. One end of the connecting part is provided with a connecting thin tube connected to the open end in a sleeving manner. The other end of the connecting thin tube is connected with the combination part. The injection unit comprises an injection tube connected to the combination part in a sleeving manner, and a squeeze part disposed inside the injection tube. The nasal passage irrigation catheter device has the advantages that the catheter unit is put deep in the nasal cavity for irrigation, discomfort of a patient with nasosinusitis is soothed indeed, and the simple combination of the catheter unit and the injection unit allows a user to conveniently operate the nasal passage irrigation catheter device with no need for assistance from other people.

Description

technical field [0001] The invention relates to a nasal washing device, in particular to a nasal channel washing catheter device which can be carried around, operated by itself and conveniently assembled and disassembled. Background technique [0002] In recent years, with the development of industry and climate change, air pollution has become more and more serious, which has a great impact on life. According to the Medscape website (http: / / emedicine.medscape.com / article / 232791- overview#a0156), about 14.6% of people in the United States suffer from chronic sinusitis, and it is conservatively estimated that it will cause about 18-22 million visits to the doctor and direct medical costs of US$3.4-5 billion per year, although so much medical expenses have been spent , but the incidence is still increasing every year. Relevant literature also pointed out that air pollution, humidity and high concentration of pollen are related to the high prevalence rate of this disease, and...

Problems solved by technology

[0008] According to the above description, it can be seen that what patients with sinusitis really need to clean is the viscous secretions in the upper nasal passage A1 and the middle nasal passage B1. Although the known nasal irrigator can be cleaned by applying force to the squeezing part 10 and the water in the internal space 11 is pushed into the extension pipe portion 22, and then sprayed out from the outlet 21 to achieve the function of washing the nasal vestibule, but it is also limited by the nozzle 20 because it is too hard and too large to In-depth, only a single water column from front to back can be sprayed in the nasal vestibule, so it can only be washed to the lower nasal passage C1 or the wider and more normal parts with less resistance. For the deeper upper nasal passage A1 and middle nasal passage B1 However, it cannot be flushed, so it cannot really relieve the discomfort of the patient, and if the symptoms continue, one day the sinus outlet will be blocked and mucus will accumulate in the sinus, causing acute sinusitis or other complications, which will cost expensive medical expenses

[0009] In addition, the water column may be too strong and easily damage the mucous membranes, and improper control of the water volume may also cause choking
