Description

A tracheotomy tube with both air bag compression prevention and suction functions

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a tracheotomy catheter with both air bag compression prevention and suction functions.

Background Art

An artificial airway is a gas passage established by inserting a catheter into the trachea through the mouth/nose or tracheotomy, which can correct the patient's hypoxia and improve ventilation function. An artificial airway is an effective means to ensure a patency of the airway and plays an extremely important role in the rescue process. However, the establishment of an artificial airway will also damage and destroy the body's normal physiological and anatomical functions to a certain extent, causing harm to the patient;

The existing patent (Announcement No.: 202320538976.9) double-balloon tracheotomy catheter is an improvement on the single-balloon tracheotomy catheter currently used in hospitals. The traditional balloon cannot change the relative position of the balloon in the airway after insertion into the trachea. The long-term compression of the balloon on the tracheal mucosa at the same position can lead to ischemia, ulcers, and even serious complications such as bleeding and perforation of the mucosa in the area.

In response to the above problems, the existing patent provides a solution: through the use of dual airbags, the airbags are used alternately during use to avoid the compression of the tracheal mucosa caused by applying force to one position for a long time, and the foreign objects in the patient's mouth are cleaned through a negative pressure suction tube, reducing the reflux of saliva/gastric juice and aspiration, and preventing tracheal tympanic membrane damage and the occurrence of VAP.

However, with respect to the improvement of the artificial airway, the existing patents ignore the problem of the artificial airway falling off and shifting when the patient turns over or the medical staff performs other treatments; because the patients who need to use the artificial airway are critically ill patients who cannot move independently, and the patients need to use the artificial airway for a long time, the traditional fixation method is to fix it to the patient's skin with medical tape. This has two disadvantages. First, when cleaning the tracheal airway, the artificial airway needs to be repeatedly disassembled and installed. The skin is repeatedly pulled and compressed by the medical tape, which will cause damage and ulceration, and the medical tape will cause pressure on the pipeline, which will affect the fluidity of the airflow inside the pipeline; in addition, the existing technology all uses a hose, and the tube body needs to be operated by medical staff when in use. Twisting and bending will cause the hose to close, affecting the fluidity inside the artificial catheter.

Utility Model Content

The utility model aims to provide a tracheotomy catheter that combines the functions of preventing airbag compression and suction, so as to solve the problem in the above-mentioned background technology that an artificial airway is fixed to the patient's skin by medical tape, and the artificial airway needs to be repeatedly disassembled and installed when cleaning the tracheal airway. The skin is repeatedly pulled and compressed by the medical tape, which may cause damage and ulceration, and the medical tape may cause pressure on the pipeline, which may affect the fluidity of the airflow inside the pipeline.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a tracheotomy catheter body, wherein one end of the top of the tracheotomy catheter body is connected with airbag inflation connection port 1, airbag inflation connection port 2, and airbag inflation connection port 3, and airbag inflation connection port 1, airbag inflation connection port 2, and airbag inflation connection port 3 are respectively connected to airbag 1, airbag 2, and airbag 3; one end of the bottom of the tracheotomy catheter body is connected with negative pressure suction hole 1, negative pressure suction hole 2, and negative pressure suction hole 3; a connector is installed at the top of the tracheotomy catheter body, and a positive magnetic suction block is installed at the bottom of the connector.

Preferably, the connector has a right-angle shape.

Preferably, positioning locks are fixed on both sides of the positive magnetic block, a negative magnetic block is provided at one end of the positive magnetic block, and the negative magnetic block and the positive magnetic block are in a magnetic attraction relationship. The end of the negative magnetic block away from the positive magnetic block is fixed to the headgear, neck strap and arm strap worn on the patient's body.

Preferably, the tracheotomy catheter body is made of hollow thin-walled soft silicone material, and the top is connected to a ventilator connection port. Preferably, airbag one, airbag two, and airbag three are respectively provided with airbag inflation hole one, airbag inflation hole two, and airbag inflation hole three, and the airbag inflation hole one, airbag inflation hole two, and airbag inflation hole three are embedded in the outer edge of the tracheotomy catheter body. Preferably, the negative pressure suction hole one, negative pressure suction hole two, and negative pressure suction hole three are respectively located above airbag one, airbag two, and airbag three, and are respectively connected to negative pressure suction connection port one, negative pressure suction connection port two, and negative pressure suction connection port three. Preferably, a tracheotomy catheter port is provided at one end of the tracheotomy catheter body away from the ventilator connection port.

Preferably, the tracheotomy tube inner core is connected to the tracheotomy tube body and is located inside the tracheotomy tube body. The overall length of the tracheotomy tube body is longer than the tracheotomy tube inner core, and the diameter of the tracheotomy tube inner core is smaller than the diameter of the tracheotomy tube body.

Compared with the prior art, the beneficial effects of the utility model are:

(1) The right-angle shape of the connector makes it easy to connect the ventilator connection port to the top of the ventilator, avoiding bending of the tube during operation. The hard material can protect the hose near the ventilator connection port that often needs to be operated. Because the tube needs to be operated by medical staff during use, twisting and bending will cause the hose to close and affect the flow inside the artificial catheter;

(2) The positive magnetic block and the negative magnetic block are magnetically attracted to each other, so that the airway can be easily fixed on the patient's head, neck and arms, which solves the problem of the artificial airway falling off and shifting when the patient turns over or when the medical staff performs other treatments. Because the patients who need to use the artificial airway are critically ill patients who cannot move independently, they need to use the artificial airway for a long time. The advantage of this structure is that it avoids repeated disassembly and installation of the artificial airway when cleaning the trachea and airway, which causes the skin to be repeatedly pulled and compressed by the medical tape, causing damage and ulceration. Compared with the soft and easily deformable medical tape, the hard positive magnetic block can fix the tube body without compressing the tube. The function of the positioning lock is to locate the direction of the tracheotomy tube body to avoid the tracheotomy tube body being twisted and fixed when fixed, which affects the fluidity of the liquid inside the tube body.

(3) By using three airbags, any one of the three airbags can be used intermittently. When one of the airbags is to be deflated, the corresponding negative pressure suction hole on it must first suck out the airway secretions, then inflate one of the other two airbags, and then deflate the airbag to be deflated. Its function is to change the relative position of the airbags at regular intervals, reduce its pressure on the fixed airway mucosa, and reduce the occurrence of airway mucosal ischemia, ulcers, bleeding, and perforation;

(4) Negative pressure suction holes are provided on the tracheotomy catheter body, which are located above the airbags and are connected to the negative pressure suction connection ports. When one of the airbags is to be deflated, the corresponding negative pressure suction hole on it is first used to suck out the airway secretions, and then one of the other two airbags is inflated, and then the airbag to be deflated is deflated. Suction on the airbag can be achieved through the negative pressure inlet hole and the negative pressure suction connection port. The function of suction is to remove saliva or gastric juice that flows into the airway from the mouth and is blocked by the airbag above the airbag at any time, so as to prevent these bacteria-carrying liquids from flowing into the lower respiratory tract, thereby reducing the occurrence of pneumonia.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The airbag inflation connection port 1 4, the airbag inflation connection port 2 5, and the airbag inflation connection port 3 6 are respectively connected to the airbag 1 13, the airbag 2 14, and the airbag 3 15; one end of the bottom of the tracheotomy catheter body 1 is connected to the negative pressure suction hole 10, the negative pressure suction hole 2 11, and the negative pressure suction hole 3 12; the top of the tracheotomy catheter body 1 is installed with a connector 3, and the bottom of the connector 3 is installed with a positive magnetic suction block 20;

The connector 3 has a right-angle shape;

Positioning lock buckles 21 are fixed on both sides of the positive magnetic block 20, and a negative magnetic block 22 is provided at one end of the positive magnetic block 20, and the negative magnetic block 22 and the positive magnetic block 20 are in a magnetic attraction relationship. The end of the negative magnetic block 22 away from the positive magnetic block 20 is fixed to the headgear, neck strap, and arm strap worn on the patient's body;

The tracheotomy catheter body 1 is made of hollow thin-walled soft silicone material, and the top is connected to a ventilator connection port 2 for connecting to the patient end of the ventilator for mechanical ventilation; or connecting to a respiratory humidification therapy device for oxygen inhalation;

The airbag inflation connection port 1 4, the airbag inflation connection port 2 5, and the airbag inflation connection port 3 6 are respectively connected to the airbag 1 13, the airbag 2 14, and the airbag 3 15. The connection port can be connected to a syringe, and air can be injected into one of the airbags 1 13, the airbag 2 14, and the airbag 3 15 at any time; the airbags in different parts can be inflated every few hours, and the other two airbags can be deflated to prevent the airbags in fixed positions from continuously pressing; the airbags can be fixed to the patient's airway after being inflated; when the position of the airbags needs to be changed, when one of the airbags is to be deflated, the airway secretions must first be sucked out through the corresponding negative pressure suction hole on it, and then one of the other two airbags can be inflated, and then the airbag to be deflated is deflated;

In addition, airbag 1 13, airbag 2 14, and airbag 3 15 are located at different parts of the tracheotomy catheter body 1, and are made of hollow thin soft silicone. They are in a collapsed state before insertion, and the airbag wall is close to the catheter, which is convenient for inserting the tracheotomy catheter from the tracheotomy opening; after being inserted to a proper position, the airbag inflation connection port is selected according to actual needs to inject air into the airbag inflation hole, so that one of the airbags is full and round, and can fit closely with the inner wall of the trachea, so as to achieve a relatively fixed effect; the role of the airbag, on the one hand, can form a closed breathing circuit to avoid abnormal alarms of the ventilator caused by air leakage of the ventilator, and can also block the secretions of the upper respiratory tract from flowing into the lower respiratory tract, so as to avoid the occurrence of atelectasis and pneumonia;

And the airbag one 13, airbag two 14, and airbag three 15 are respectively provided with an airbag inflation hole one 17, an airbag inflation hole two 18, and an airbag inflation hole three 19, and the airbag inflation hole one 17, the airbag inflation hole two 18, and the airbag inflation hole three 19 are embedded in the outer edge of the tracheotomy catheter body 1; they are small holes on the outer edge of the tracheotomy catheter body 1, and in actual use, airbags in different parts can be inflated every few hours, and the other two airbags are deflated to prevent the airbags in fixed positions from continuously pressing; in addition, when the tracheotomy catheter is properly placed and needs to be fixed, an empty syringe is used to inflate the airbag one 13, the airbag two 14, and the airbag three 15 through the airbag inflation connection port one 4, the airbag inflation connection port two 5, and the airbag inflation connection port three 6, respectively, from the airbag inflation hole one 17, the airbag inflation hole two 18, and the airbag inflation hole three 19, so that the airbags can fit closely with the tracheal wall;

The negative pressure suction hole 10, the negative pressure suction hole 2 11, and the negative pressure suction hole 3 12 are respectively located above the airbag 1 13, the airbag 2 14, and the airbag 3 15, and are respectively connected with the negative pressure suction connection port 1 7, the negative pressure suction connection port 2 8, and the negative pressure suction connection port 3 9; the negative pressure suction hole 10, the negative pressure suction hole 2 11, and the negative pressure suction hole 3 12 are hollow pipes, which are close to the outer wall of 1, and the lower ends are opened to the airbags 13, 14, and 15 above the outer wall. The negative pressure suction hole 10, the negative pressure suction hole 2 11, and the negative pressure suction hole 3 12 on the airbag are inflated when in use. The airbag is in close contact with the inner wall of the trachea, and the secretions accumulated in the airway are accumulated above the airbag. After negative pressure suction through the negative pressure suction connection port 1 7, the negative pressure suction connection port 2 8, and the negative pressure suction connection port 3 9, the secretions can be sucked out from the small opening, thereby reducing the secretions from flowing into the airway and deep lung tissue below the airbag, and avoiding the occurrence of atelectasis and pneumonia.

When one of the airbags is to be deflated, the corresponding negative pressure suction hole on it must first be used to suck out the airway secretions, then one of the other two airbags must be inflated, and then the airbag to be deflated must be deflated; this reduces the occurrence of ischemic ulcers, bleeding, and perforations of the airway mucosa caused by continuous compression of the airbag; its suction function is to remove saliva or gastric juice that flows into the airway from the mouth and is blocked above the airbag at any time, preventing these bacteria-carrying fluids from flowing into the lower respiratory tract, thereby reducing the occurrence of atelectasis and pneumonia;

A tracheotomy tube port 16 is provided at one end of the tracheotomy tube body 1 away from the ventilator connection port 2; the tracheotomy tube port 16 is located at the end of the tracheotomy tube body 1, and when in use, the tube port faces the trachea, and mechanical ventilation can be performed. If necessary, a fiber bronchoscope or a sputum suction tube can also be inserted from the ventilator connection port 2, and enter the lower respiratory tract through this tube port to perform sputum suction and other operations;

The tracheotomy tube inner core 23 and the tracheotomy tube body 1 are connected through and located inside the tracheotomy tube body 1. The tracheotomy tube inner core 23 is made of hard plastic material, which is harder than the tracheotomy tube body 1. It is located outside the ventilator connection port 2 and is shorter than the tracheotomy tube body 1 in overall length. It is used for shaping and guiding. The overall length of the tracheotomy tube body 1 is longer than the tracheotomy tube inner core 23. The diameter of the tracheotomy tube inner core 23 is smaller than the diameter of the tracheotomy tube body 1.

Working principle: When the utility model is used, first of all, the critical care department admits a large number of patients who need long-term mechanical ventilation or patients who need tracheotomy due to coma and weak spontaneous choking reaction, and perform spontaneous breathing through the tracheotomy tube for a long period of time. During long-term mechanical ventilation, ordinary tracheotomy tubes are of fixed length, and the relative position of the airbag in the airway cannot be changed after insertion into the trachea. After a period of time, the airbag will compress the tracheal mucosa in the same position for a long time, which will cause tracheal mucosal ischemia, ulcers, inflammation, necrosis, stenosis of the damaged trachea, and even tracheoesophageal fistula. In addition, most patients with tracheotomy in the critical care department need sedation, analgesia, and even muscle relaxation during mechanical ventilation. They cannot actively swallow saliva, and the protective cough reflex disappears. Although patients in the early stages of recovery are conscious, most of them have problems such as poor muscle strength, swallowing difficulties, and weak cough reflexes. Both of these conditions can cause saliva swallowing difficulties, and the saliva remaining in the mouth can be easily inhaled into the respiratory tract; patients with poor gastrointestinal function or even gastric retention may also experience gastric juice reflux into the mouth and inhalation into the respiratory tract. Whether saliva or gastric juice flows into the airway, it is extremely harmful to the patient, causing complications such as atelectasis and pneumonia, and more seriously leading to sepsis, which seriously affects the patient's clinical prognosis, increases hospitalization time and even increases mortality.

The design of this embodiment is to take the above two problems into consideration and improve them one by one to achieve:

There are three airbags on the main body of the tracheotomy tube. You can use any of the three airbags intermittently. When one of the airbags is to be deflated, first suck out the airway secretions through the corresponding negative pressure suction hole on it, then inflate one of the other two airbags, and then deflate the airbag to be deflated. Its function is to change the relative position of the airbags at regular intervals, reduce its pressure on the fixed airway mucosa, and reduce the occurrence of airway mucosal ischemia, ulcers, bleeding, and perforation.

At the same time, when one of the airbags is to be deflated, the corresponding negative pressure suction hole on it must first be used to suck out the airway secretions, then one of the other two airbags must be inflated, and then the airbag to be deflated must be deflated. Suction on the airbag can be achieved through the negative pressure inlet hole and the negative pressure suction connection port. The suction function is to remove saliva or gastric juice that flows into the airway from the mouth and is blocked above the airbag at any time, preventing these bacteria-carrying liquids from flowing into the lower respiratory tract, thereby reducing the occurrence of pneumonia.

Afterwards, the right-angle shape of the connector 3 makes it easy to connect the ventilator connection port 2 to the top of the ventilator, avoiding bending of the tube during operation, and the hard material can protect the hose near the ventilator connection port 2 that often needs to be operated. Because the tube needs to be operated by medical staff during use, twisting and bending will cause the hose to close and affect the fluidity inside the artificial catheter.

Finally, the positive magnetic block 20 and the negative magnetic block 22 are magnetically attracted to each other to facilitate fixation on the patient's head, neck and arms, thereby solving the problem of artificial airway falling off and shifting when the patient turns over or medical staff perform other treatments; because patients who need to use artificial airways are critically ill patients who cannot move independently, patients need to use artificial airways for a long time. The advantage of this structure is that it avoids repeated disassembly and installation of artificial airways when cleaning the tracheal airway, which causes the skin to be repeatedly pulled and compressed by medical tape and damaged and ulcerated. Compared with soft and easily deformable medical tape, the hard positive magnetic block 20 can fix the tube body without compressing the tube; the function of the positioning lock 21 is to locate the direction of the tracheotomy catheter body 1 to avoid the tracheotomy catheter body 1 being twisted and fixed when fixed, which affects the fluidity of the liquid inside the tube body.

It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
