[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1

[0028] Reference Figure 1-4, which is the first embodiment of the utility model, provides an airbag-mounted easy-suction endotracheal tube, which includes an outer tube unit 100, including an outer tube body 101, and a ventilator connecting tube 102 arranged at one end of the outer tube body 101; a connecting tube unit 200, including a connecting tube body 201 arranged at the other end of the outer tube body 101, a sealing belt 202 arranged inside the connecting tube body 201, and a suction hole 203 opened on the outside of the connecting tube body 201; an intubation unit 300, including an intubation body 301 arranged at the other end of the connecting tube body 201, and an airbag 302 arranged on the outside of the intubation body 301, so that medical personnel can insert the intubation into the patient's oral cavity and throat through the intubation body 301, thereby performing surgical treatment on the patient.

[0029] Among them, the number of suction holes 203 is at least two, and the two suction holes 203 are evenly surrounded and located on the outside of the connecting tube body 201. The secretions and sputum above the air bag in the patient's throat are simultaneously attracted in two directions through at least two suction holes 203, thereby solving the problem that the disposable suctionable sterile endotracheal tube cannot completely attract the secretions or sputum above the air bag in the patient's throat, and reducing the cleaning time of medical staff, thereby reducing the labor intensity of medical staff and increasing the comfort of medical staff.

[0030] Furthermore, a connecting groove 204 is opened inside the sealing belt 202, and the inflation tube 103 can pass through the sealing belt 202 and be connected to the airbag 302 through the connecting groove 204, thereby not affecting the inflation of the airbag 302 during use, blocking the patient's throat, and at the same time, the suction tube outer tube 105, the sealing belt 202, and the suction hole 203 attract secretions and sputum above the airbag in the patient's throat without interfering with each other.

[0031] During use, the medical staff first installs the device, then opens the patient's mouth, observes the patient's oral cavity and throat through an endoscope, and then inserts the cannula body 301 into the patient's body along the patient's oral cavity and throat. After the insertion is completed, the tracheal mask 104 is opened, and the inflation tube 103 is connected to the inflation device to inflate the air bag 302 outside the cannula body 301 until the air bag 302 swells and completely blocks the patient's throat. At this time, the inflation is stopped, the tracheal mask 104 is closed again to seal the air inlet of the inflation tube 103, and then the ventilator connecting tube 102 is connected to the ventilator; wait for it to work for a period of time Afterwards, a certain amount of secretions and sputum will be produced above the airbag in the patient's throat. At this time, the medical staff connects the suction tube to the suction head 106, and then forms a negative pressure between the sealing belt 202 and the connecting tube body 201 through the suction tube outer tube 105 and the suction tube connector 107, so that the two suction holes 203 simultaneously attract the secretions and sputum above the airbag in the patient's throat in two directions, thereby solving the problem that the disposable absorbable sterile endotracheal tube cannot completely attract the secretions or sputum above the airbag in the patient's throat, thereby reducing the cleaning time and labor intensity of medical staff, and increasing the comfort of medical staff.

[0032] Example 2

[0033] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: an inflation tube 103 is provided on the outside of the outer tube body 101, and a tracheal cover 104 is provided at one end of the inflation tube 103. A suction tube outer tube 105 is provided on the outside of the outer tube body 101 and is located on the opposite side of the inflation tube 103. A suction head 106 is provided at one end of the suction tube outer tube 105, and a suction tube connector 107 is provided at the other end of the suction tube outer tube 105. The size of the inflation tube 103 is matched with the size of the connecting groove 204, so that the inflation tube 103 and the sealing belt 202 will be close to the inner wall of the connecting tube body 201, so that the sealing belt 202 and the inflation tube 103 will not affect the patient's breathing, thereby increasing the patient's comfort.

[0034] Compared with Example 1, further, the central axis of the sealing belt 202 is parallel to the central axis of the connecting tube body 201, and the two ends of the central axis of the sealing belt 202 are set as arc surfaces 202a, and the arc surfaces 202a reduce the wind resistance generated by the patient breathing through the intubation body 301, the sealing belt 202, and the outer tube body 101, thereby further increasing the patient's comfort.

[0035] During use, the air bag 302 will first be inflated and swelled to block the patient's throat, thereby preventing secretions or sputum in the patient's oral cavity from entering the patient's body and causing infection. However, oxygen needs to be supplied to the patient's body at this time, so the ventilator connecting tube 102 needs to be connected to the ventilator, so that the oxygen breathed by the patient passes through the outer tube body 101, the sealing belt 202, and the cannula body 301 in sequence, thereby supplying oxygen to the patient's chest cavity and body to maintain the oxygen demand in the body. As for the arc surface 202a, when the patient inhales and exhales, the airflow will pass through the outer tube body 101, the sealing belt 202, and the cannula body 301, and the arc-shaped sealing belt 202 reduces the resistance generated when the airflow passes through the sealing belt 202, so that the patient does not need to use more effort to inhale or exhale, thereby breathing is smoother, which increases the patient's comfort.

[0036] The remaining structures are the same as those of Example 1.

[0037] Example 3

[0038] Reference Figure 1-4 , which is the third embodiment of the utility model. This embodiment is different from the second embodiment in that the end of the cannula body 301 is an arc-shaped inclined surface, which is convenient for medical personnel to insert the cannula body 301 into the patient's throat without causing damage to the patient's throat. The distance between the sealing belt 202 and the top of the airbag 302 is between 0.3cm and 0.5cm, so that the sealing belt 202 will not affect the inflation of the airbag 302, and also reduces the blind area of ​​the bottom of the sealing belt 202 to attract secretions or sputum, thereby reducing the amount of secretions or sputum retained in the patient's mouth.

[0039] Compared with Example 2, further, the contact edges between the two sides of the suction hole 203 and the connecting tube body 201 opened therein are provided with rounded corners 203a, so that the suction tube connector 107 can absorb the secretions and sputum above the airbag in the patient's throat into the space between the sealing belt 202 and the connecting tube body 201, and then sequentially suck and discharge them through the suction tube connector 107, the suction tube outer tube 105, and the suction head 106, thereby cleaning the patient's oral cavity and reducing the incidence of ventilator-associated pneumonia in the patient.

[0040] During use, since the patient's throat is blocked by the inflated air bag 302, and the patient's mouth and trachea will produce a small amount of secretions or sputum, medical personnel are required to regularly suck out the secretions or sputum in the patient's mouth to prevent the secretions or sputum from infecting the patient. The arcs on both sides of the suction hole 203 and the suction head 106 connected to the suction device generate negative pressure in the space between the sealing belt 202 and the connecting tube body 201. The negative pressure causes the secretions or sputum on the outside of the connecting tube body 201 to enter between the two along the outside of the suction hole 203. The fillet 203a is an arc, which reduces the resistance of the secretions or sputum entering the connecting tube body 201 and the sealing belt 202, making it easier to negatively pressure the sealing belt 202 to attract the secretions and sputum above the air bag in the patient's throat, thereby cleaning the patient's mouth and reducing the incidence of ventilator-associated pneumonia in the patient.

[0041] The remaining structure is the same as that of Example 2.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
