Description

Eustachian tube insertion mechanism {EUSTACHIAN TUBE PLUG DEVICE}

The present invention relates to a device to be inserted into an ear canal, and to an ear canal insertion device that is inserted to treat an open ear canal, a disorder in which the ear canal is occasionally or continuously opened.

Open ear canal is a symptom of a physical disorder in which the ear canal is occasionally opened continuously. You experience self-resonance, and you hear the sound inside the body along with the ringing of your words. In severe cases, all the breathing, speech, swallowing, and heartbeat sounds of the patient, which are inaudible to the normal person, generate a bucket on the head effect in the patient and directly vibrate the eardrum.

Symptoms of patients with open ear canal can range from transients to cases where there is a great obstacle to daily life. Transient symptoms that occur during pregnancy may disappear naturally after childbirth, and when weight is suddenly lost due to excessive diet, symptoms may disappear as the weight is recovered. If it is not such a transient symptom, it causes a significant obstacle to the patient's social activities. In this case, treatment should be actively attempted.

Until now, the treatment of open ear canals is divided into medical treatment and surgical treatment. The medical treatment is the nasal mucosa of the ear canal with Premarin nasal fluid, SSKI (saturated solution of potassium iodide), an anticholinergic component of atropine, etc., which are estrogen agents that cause swelling of the nasopharynx inlet mucosa of the ear canal or nasal saline instillation. It can be applied as an initial treatment through the generation of edema.

As a more direct treatment, surgical treatment includes tympanic incision and ventilation tube insertion, tympanic stiffness increase, ear canal nasopharyngeal inlet injection, nasopharyngeal ear canal entrance catheter insertion, middle ear ear canal entrance plug or catheter insertion, palatal length muscle dislocation and wing hook resection, There are various methods, such as transfer closure. The tympanic incision and ventilation tube insertion are limited to symptom relief for changes in middle ear pressure and tympanic movement, and it is thought that there is little effect on self-hearing, and the increase in tympanic stiffness can be expected to relieve the subjective symptoms of open ear canal. It is reported that, and the infusion at the entrance of the esophagus nasopharynx does not have a high symptom improvement rate compared to the difficult procedure. In addition, insertion of the catheter at the entrance of the nasopharynx has a high possibility of spontaneous escape of the catheter, and the resection of the palatal length muscle dislocation and wing hook resection is required, and the ear canal obstruction can completely eliminate the symptoms of open ear canal, but permanent In some cases, a ventilation tube implantation is required.

Accordingly, the present invention is to propose an ear canal insertion device that can be used in the middle ear ear canal inlet plug or catheter insertion technology.

The steroid reduces foreign body reactions inside the ear canal.

Hereinafter, the present invention is intended to identify the form that is most easily maintained after insertion into the transfer tube by manufacturing the transfer tube insertion device in various forms.

1) Size ratio of tail

The ear canal insertion device was manufactured in the size and shape of FIGS. 4 to 7.

In the first embodiment (Fig. 4), the vertical length of the locking part is 4 (mm), the length of the head is 5 (mm), and the length of the tail is 18 (mm), The length was manufactured to be 23 (mm), but the one end portion extending from the tail portion to the head portion was 1.5 (mm) and the other end portion of the tail portion was manufactured to be 1 (mm).

In the second embodiment (Fig. 5), the vertical length of the locking part is 4 (mm), the length of the head is 5 (mm), and the length of the tail is 18 (mm), The length was manufactured to be 23 (mm), but one end portion extending from the tail portion to the head portion was 2.0 (mm) and the other end portion of the tail portion was manufactured to be 1 (mm).

In the third embodiment (Fig. 6), the vertical length of the locking part is 4 (mm), the length of the head is 5 (mm), and the length of the tail is 18 (mm), The length was manufactured to be 23 (mm), but one end portion extending from the tail portion to the head portion was 2.0 (mm) and the other end portion of the tail portion was manufactured to be 1.5 (mm).

In the fourth embodiment (Fig. 7), the vertical length of the locking part is 4 (mm), the length of the head is 5 (mm), and the length of the tail is 18 (mm).

The ear canal insertion mechanism manufactured according to the first embodiment (Fig. 4) tends to slide because one end of the tail becomes relatively narrow and the head becomes narrow, so that it is difficult to become caught in the valley of the ear canal. Since the other end of the tail is wide, the flow of air entering and leaving the ear canal is weakened, making it difficult to control the internal pressure of the patient.

In addition, the transfer pipe insertion mechanism manufactured according to the second embodiment (FIG. 5) is a shape that best satisfies the relative ratio of one end of the tail and the other end, and the formation of the hooking of the head is the most natural, and It was possible to solve the problem caused by the open transfer card because the air entering and exiting was the easiest to flow.

In addition, the transfer tube insertion device manufactured according to the third embodiment (FIG. 5) has a problem in that it is difficult to control the internal pressure of the patient because the other end of the tail portion is relatively widened, and the flow of air entering the transfer tube is weakened.

In addition, the ear canal insertion device manufactured according to the fourth embodiment (Fig. 6) is very difficult to control the internal pressure of the patient because the size of one end and the other end of the tail is too wide, so that the flow of air entering the ear canal is weak. There was a problem.

Therefore, it can be seen that the ear canal insertion device manufactured in the second embodiment (FIG. 5) is most preferable.

2) Cross-sectional shape of the tail

As shown in Figs. 8(a) to (e), various cross-sectional shapes of the tail of the ear canal insertion device according to the present invention are manufactured, and the shape that is most easily maintained after insertion into the ear canal was confirmed.

In the case of (a), the cross section was provided in an elliptical shape, and when inserted into the ear canal, a part of the oval was provided so as to contact the ear canal to prevent slipping of the ear canal insertion device and was most suitable for patients with open ear canal.

In the case of (b), it was confirmed that the cross-section was provided in a circular shape, and when inserted into the ear canal, any of the rounds did not contact the ear canal and had no resistance, and it was confirmed that the air flow in the ear canal was too large to be suitable for patients with open ear canal. Became.

In the case of (c), it was confirmed that the cross-section was provided in a rectangular shape, and because of the rectangular corners, insertion into the ear canal is very inconvenient and there is insufficient space for air flow in the ear canal, which is not suitable for patients with open ear canal.

In the case of (d), the cross-section is rectangular and the corners are smooth, and it was inserted into the ear canal more easily than the (c) shape, but as in the (c) shape, there is insufficient space for airflow in the ear canal, so that It was found to be unsuitable.

In the case of (e), it was confirmed that the cross-section was prepared in a triangular shape, and it was very inconvenient to be inserted into the ear canal due to the corner of the triangle, and the air flow in the ear canal was too large to be suitable for patients with open ear canal.

Therefore, it is preferable that the cross section of the tail is manufactured in a circular shape.

By means of solving the above problems, the present invention can provide an ear canal insertion mechanism that can be used in a middle ear ear canal inlet plug or catheter insertion technique, and can be inserted into an ear canal and used permanently.

In addition, the present invention can provide an ear canal insertion mechanism provided with a locking part so as not to slip or fall out of the ear canal even when the patient sneezes or moves.
