Description

IRRIGATION DEVICE -. cavities of the MID

The utility model relates to medicine, more precisely to otorhinolaryngology, and can find application in the treatment of purulent otitis media.

Chrona purulent otitis media otitis media (JCrcO) is not only one of the 11 most common diseases of ENT organs, but also one of the causes of hearing loss. According to the literature, of the total number of patients with ENT organs diseases, about half refer to HCV. The social significance of this disease It lies not only in its potential danger to the patient's ZhR13NI, but also in the fact that it often causes severe hearing loss, and therefore the patient's working capacity is reduced. The question of the causes of the chronic inflammatory process, including HCGS, has not been finally clarified. It is known that previously etiopathogenesis of KGSO was studied mainly from the standpoint of the decisive role of the microbial agent. Over the past decades, a unanimous judgment has been made that the occurrence and development of this disease is of primary importance to the reactivity of the organism with its many defenses adapt mechanism me.

Based on the fact that HCGS is a disease in the development of which various pathogenic flora plays a role, disorders of the humoral and cellular immunity systems, pathology of the upper Hiiu of the respiratory tract (airways), changes in the function of the auditory tube, treatment must be very complex and consist of , according to indications, antibacterial agents and the conduct of an event aimed at restoring general and local immunity, in eliminating the chronic foci of infection in the SSS and in restoring the function of the auditory tube.

In recent years, the mechanisms of immunological valuation in inflammatory diseases of the middle ear have become the subject of intensive study. It was shown that the effectiveness of treatment with TCO is directly dependent on the state of the patient’s immune system, and the degree of inflammation in the middle ear depends on the condition of the so-called local 11 immunity,

The most informative in terms of studying secretory immunity is the method of studying swabs from the middle ear cavity. Despite the great value of the methods for studying flushing fluid, they were not widely used in otiatrics. One of the prryin, slowing down, its distribution to them, is the lack of tools for sampling from the middle ear cavity.

Currently known: - device (1), consisting of an ear funnel with soldered metal tubes aJ-4i; - a device (g) in the syringe with a replaceable nozzle.sh, including for washing the tympanic cavity; device (3), consisting of two ear funnels, moreover, one BopoHis, of a larger diameter, is located outside, a smaller one inside. A metal funnel has been soldered to an empty funnel through which it is fed into the tympanic cavity. Through a tube soldered to an internal funnel, the liquid passively flows out of the bsch) abyssal cavity,

All these devices, however, due to the lack of emphasis in the area of the external auditory meatus, can injure the mucous membrane of the tympanum; in the absence of the necessary tightness, it is impossible to get a flush from the middle ear without

losses, it is impossible to exclude vaginal contamination of the investigated mother. evil; as a result of the presence of several Taaie adapters, the devices are inconvenient in sterilization, during mass examinations and with children.

The technical result of this utility model is to create a structurally simple device for irrigation of the middle ear cavity, suitable for diagnostic and therapeutic purposes, allowing to exclude injuries of the mucous membrane of the middle ear.

This result is achieved by the fact that in the known device for receiving a flush from the middle ear cavity, containing leading and diverting tubes, there is an additional ear-shaped obturator with a through channel for accommodating the tubes, moreover, the obturator and the tubes are made of elastic material.

The pressure of the ear obturator ensures tightness in the area of the external auditory meatus and thereby eliminates the loss and contamination of the material to be examined.

The possibility of using an individual ear obturator eliminates trauma to the mucous membrane of the tympanic cavity, which makes the device suitable for mass examination, including in children's practice.

For a better understanding of the device drive circuit (Figure 2), on which: 1-obturator, E-feeding tube, 3-diverting tube. The operation of the device is as follows: the ear obturator (1) is hermetically fixed in the external auditory meatus, along the lead tube (S) connected to

syringe Record, saline solution t (36.6 ° C), with a volume of about 5 ml, is introduced into the tympanic cavity. and along the discharge tube (3), the physical solution, having washed the olia membrane of the tympanic cavity, passively flows into a centrifuge tube sent for examination.

The device we offer, in comparison with the known ones, has a number of advantages:

-in view of the presence of an elastic ear obturator, tightness is ensured when a flush is obtained from the baryan cavity, which eliminates the loss of the test material, as well as its pollution;

-dense fixation of the device in the area of the external hearing: the new passage ensures complete non-invasiveness of the study;

- simplicity of design provides ease of sterilization;

-the device allows you to carry out activities related to irrigation of the mucous membrane of the tympanum with medicinal products

The device for irrigation of the mucous cavity of the middle ear was developed at the Clinic for Restorative Ear Surgery in St. Petersburg, ear, throat, nose and speech, and it was tested during examination and treatment of about 100 patients. Authors Patent
