Intelligent positive-pressure constant-temperature bionic full-automatic nasal-cavity irrigation treatment device

Abstract

The invention belongs to the department of otolaryngology-head and neck and field of washing and therapeutic apparatus for nasal cavity, which aims at recovering the physiological function of nasal mucosa cilium system. The washing and therapeutic apparatus for nasal cavity comprises a forming system of bionic massage washing stream with adjustable pressure and an intelligent constant temperature system; the core of the main body is controlled by an 892051 single chip microcomputer which also carries out digital control for the temperature of washing stream and for the frequency as well as pressure of the bionic massage washing stream, while the flow rate is controlled and regulated manually. The constant temperature ranges between 35 and 42 DEG C; the frequency of the bionic massage washing stream ranges from 15 to 25 times per second; the pressure of water columns is regulated between 10 and 15 cmH2O(0.98 to 1.47KPa); and the regulation range of the flow rate is fixed between 70 and100ml per minute. A liquid medicine container and an insulated heating container with heat transfer are combined to be a 'dual-container structure' so as to avoid electric leakage and denaturation and going-bad of the washing liquid medicine after being heated directly. The positive-pressure bionic massage washing stream from the washing and therapeutic apparatus can effectively recover the physiological function of nasal mucosa cilium system and realize the therapy of nasal diseases, thus having wide potential application and high clinical value.

Description

【Technical field】 [0001] The invention relates to a fully automatic nasal cavity flushing therapeutic instrument, in particular to an intelligent positive pressure constant temperature bionic automatic nasal cavity flushing therapeutic instrument dedicated to the otolaryngology-head and neck department. 【Background technique】 [0002] The fundamental cause of complications after radiotherapy for various types of rhinitis, nasopharyngitis, and nasopharyngeal carcinoma is the specificity of the anatomical structure of the nasal-nasopharyngeal cavity and the destruction of the physiological function of the nasal mucosa-cilia system. [0003] Medical research has confirmed that the nasal cavity and sinuses have their own detoxification function under physiological conditions and maintain their own clean state, and this function is realized by the secretion, swing and transmission functions of the nasal mucosa-cilia system. If the normal shape and transmission function of cilia a...

Problems solved by technology

Although this method is simple, at the beginning of practice, many patients will have headaches and the feeling of choking water and cannot bear it, thus interrupting the treatment

Furthermore, from the point of view of modern medicine, in addition to being uncomfortable to use, most of them use ordinary water when flushing. Compared with nasal tissue fluid, ordinary water is a hypotonic solution. Damage to the nasal mucosa

[0008] 2. Traditional manual nasal irrigators have many disadvantages

[0010] First of all, the nasal wash heads of these nasal washers cannot be replaced, which is unhygienic

From a safety point of view, although some patients feel that the force of the hand-pressed rubber tube is relatively strong and the washing is relatively clean, their pressure cannot be adjusted and the controllability is poor, which brings serious danger and is likely to cause nasal mucosal damage and nasal congestion. Bleeding can even cause accidents of cerebrospinal fluid rhinorrhea; secondly, plastic bottle (or teapot-shaped) nasal irrigators rely on the gravity of water to gently flow through the nasal cavity for cleaning. The disadvantage is that the cleaning function is poor. Due to the need to tilt the head, according to human anatomy, water can easily flow into the middle ear cavity and throat through the pharyngeal opening of the nasopharynx, causing complications such as otitis media and choking

[0011] There are also some spray-type nasal irrigators or steam-type nasal irrigators on the market. Strictly speaking, they cannot be called nasal irrigators. The mist produced by them does not have positive pressure and cannot effectively enter the nasal passages and sinuses.

Therefore, it does not have the function of cleaning the nasal cavity, but can only moisten the nasal mucosa.
