Description

extracorporeal multifunctional larynx

Technical field

The utility model relates to the technical field of artificial larynx, in particular to an extracorporeal multifunctional larynx capable of recovering vocal and olfactory functions for patients undergoing total laryngectomy.

Background technique

Throat, as an important organ of the human body, has four main functions, and laryngeal cancer is a common malignant tumor in otolaryngology surgery, and its incidence rate accounts for the third place in otolaryngology. Patients with advanced laryngeal cancer have to undergo total laryngectomy. The greatest pain for patients after surgery is: 1. Loss of pronunciation and speech functions. 2. The oral cavity cannot be sucked, it is inconvenient to drink water, and it is impossible to smoke. 3. The breathing function of the nose and mouth is lost, and the trachea in the neck is permanently ostomized. The trachea is opened, and there is no filtering, heating and humidifying effect on the inhaled air. In winter, the trachea is often very dry, and the airway is prone to bleeding. 4. Due to the inability to breathe through the nasal cavity, the sense of smell is lost, the food is tasteless, and the appetite is reduced. This brings great difficulties to the patient's life and causes great psychological trauma.

For this reason, many domestic and foreign scholars have carried out unremitting exploration and research for a long time. At present, the restoration of speech function has basically been solved. It has its deficiencies, especially there is no good solution for restoring the suction action of the patient's mouth and the recovery of the patient's sense of smell, and there are no related reports, and there is no comprehensive solution for the above four major pains of the postoperative patient. solution.

Contents of the invention

In order to solve the above problems, the utility model provides an in vitro device that can restore pronunciation and speech functions without the need for the patient to undergo a second operation, and can restore the sucking action of the oral cavity and the sense of smell, and has the effect of heating and humidifying the inhaled air. Multipurpose throat.

The technical solution adopted by the utility model to solve the technical problem is: an external throat, including a pronunciation device, which is composed of a trident tube, a pronunciation tube, and an olfactory tube. The trident tube has a main pipe and two fork tubes, and one end of the olfactory tube It is connected with one fork pipe, one end of the sound pipe is connected with the other fork pipe and extends into the main pipe, the sounding device is arranged at the end of the sound pipe extending into the main pipe, and the outer end of the main pipe of the trident With connecting device.

The other end of the olfactory tube is connected with a hollow nasal plug, which has a shape suitable for insertion into the nasal vestibule; the other end of the vocal tube is connected with a short tube, which is relatively hard and allows the patient to use the upper and lower teeth. Bite; the middle part of the olfactory tube and the vocal tube is connected with a rope, which can be hung on the patient's auricle, and the olfactory tube and the vocal tube are pulled away from the corner of the mouth, which is convenient for the patient to eat.

The connecting device is a bowl-shaped cover arranged on the outer end of the main pipe of the trident tube, and the outer end of the main tube of the trident tube extends into the bowl-shaped cover. It is more suitable for patients with a tracheostomy at the top; if the outer end of the main tube is inserted into the bowl-shaped cover, and the diameter of the mouth of the main tube is slightly larger than the outer diameter of the tracheal tube, it is more suitable for patients with a tracheal tube on the neck When used by the patient, the patient's tracheal cannula can be directly connected with the main pipe of the trident tube, and it can also play a positioning role.

The edge of the bowl-shaped cover is also provided with a fixing device, which can be an elastic band arranged on the edge of the bowl-shaped cover, or two laces symmetrically arranged on the edge of the bowl-shaped cover, or can also be a Two slings are arranged symmetrically on the edge, and the ends of the slings are provided with buckles, which can facilitate patients to fix the multifunctional larynx in vitro to the neck of the utility model.

The connecting device can also be a section of connecting tube arranged at the outer end of the main tube of the trident tube, the connecting tube can be inserted into a tracheal tube in the neck of a human body, and is suitable for patients wearing a tracheal tube in the neck.

The connecting device is a section of connecting pipe arranged at the outer end of the main tube of the trident tube. The inner diameter of the connecting pipe corresponds to the outer diameter of the tracheal tube in the neck of the human body. The inner wall of the connecting pipe has an inward protrusion, and the protrusion The tracheal cannula is snap-in connected with the pit or groove on the outer wall of the tracheal cannula on the neck of the human body, and is suitable for patients wearing the tracheal cannula on the neck.

The sounding device is a diaphragm covering the port of the sounding tube, the diaphragm is strip-shaped, its width is slightly narrower than the diameter of the sounding tube port, its two ends are connected with the outer wall of the sounding tube end, and the middle covers the Most of the tube port has symmetrical gaps between its two edges and the corresponding sound tube port edges.

When using the extracorporeal multifunctional throat of the present utility model, first connect the connecting device at the outer end of the trident tube to the tracheal cannula or tracheostomy port of the patient's neck, and then insert the nasal plug at the other end of the olfactory tube into a nasal vestibule of the patient. , so that the patient breathes naturally, the airflow will be inhaled through another nasal cavity, through the olfactory area, the posterior nostril, the nasal cavity inserted into the olfactory tube, the olfactory tube, and finally enter the trachea. Such a cycle not only has the effect of filtering, heating and humidifying the inhaled air , can also restore the patient's olfactory function, so that the patient can smell various odors, and at this time, if eating, he will feel delicious; and because of such a cycle, the patient's nasal breathing can be restored, and the patient's mouth can use the negative pressure generated by lung function. Sucking action is convenient for drinking water and smoking; in order to facilitate the patient to eat, the rope connected to the middle of the olfactory tube and the vocal tube can be hung on the patient's auricle, and the olfactory tube and the vocal tube are pulled away from the corner of the mouth. When the patient needs to speak, he can use the upper and lower teeth to bite the short tube connected to the other end of the pronunciation tube, or he can hold the short tube so that the mouth of the short tube is aimed at the patient's mouth. When the tube reaches the diaphragm, the diaphragm vibrates and produces a sound in the main pipe of the trident tube, which is transmitted to the mouth, resonating with the change of the mouth shape in the excuse, and completing simple language.
