Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of tracheal intubation, and specifically relates to a tracheal intubation device with automatically adjustable balloon pressure. Background Art
[0002] Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing optimal conditions for airway patency, ventilation and oxygen supply, airway suction, etc., and is an important measure for rescuing patients with respiratory dysfunction.
[0003] After retrieval, in a tracheal intubation with visualizable and adjustable balloon pressure with the publication number of CN222304554U, this utility model discloses a tracheal intubation with visualizable and adjustable balloon pressure, including a catheter body, a balloon is arranged on the catheter body, an auxiliary sheet penetrates through the bottom of the catheter body, and the auxiliary sheet is provided with a three-way pipe extending to the outside. The right end of the three-way pipe is connected with a pressure detection table for checking the balloon pressure through a connecting pipe, the left end of the three-way pipe is connected with a balloon inflation bulb through an inflation pipe, and the middle end of the three-way pipe is connected with the subglottic airway.
[0004] The above tracheal intubation can visualize the balloon pressure, has good pressure measurement performance and is not easily contaminated, thereby reducing the contamination caused by directly detecting the balloon and complications such as tracheal intubation prolapse or airway injury caused by too low or too high balloon pressure of the tracheal intubation. However, there are still the following problems:

[0053] Further, as Figure 1 and Figure 2 shown, the adjusting mechanism 3 includes: a micro air pump 301, which is fixedly connected to the left side of the connecting pipe 204; an air filling balloon 302, which is fixedly connected to the right side of the micro air pump 301.

[0054] Through the above solution: during use, the air filling balloon 302 is filled with gas through the air filling port. When the airbag 4 expands, the pressure sensor 304 is used to feedback the pressure situation inside the airbag 4. Different from the traditional pressure gauge, the force sensor 304 detects and reacts more quickly. According to the pressure situation, the micro air pump 301 is used to control the gas inside the air filling balloon 302 to be taken in and released into the airbag 4 through the first air pipe 303.
[0055] Further, as Figure 1 、 Figure 2 and Figure 4 shown, the air deflation mechanism 5 includes: a deflation valve 501, which is fixedly connected to the right side of the air pipe interface 102.

[0056] Through the above solution: After use, the push plate 505 is used to control the rotation of the spherical valve 503, and through the exhaust hole inside it, the airbag 4 is connected to the outside world, so as to discharge the gas in the airbag 4. After the discharge is completed, the push plate 505 is released. Since the rotating shaft 504 is elastically connected to the air release valve 501 through the torsion spring 508, the push plate 505 is reset by the torsion spring 508 outside the rotating shaft 504, thereby closing the air release valve 501.
[0057] Working principle:
[0058] First, by inserting the connecting pipe 204 into the installation interface 201, the fixed insertion blocks 203 on both sides are controlled by the fixed screws 202 on both sides to be inserted into the fixed slots, so as to realize the fixed installation of the connecting pipe 204 and the installation interface 201, enabling the inflation mechanism to be installed on different tracheal intubation tubes as needed at any time.
[0059] Secondly, during use, the inflation ball 302 is inflated with gas through the inflation port. When the airbag 4 expands, the pressure sensor 304 feeds back the pressure inside the airbag 4. Different from the traditional pressure gauge, the detection and reaction of the pressure sensor 304 are more rapid. According to the pressure situation, the micro air pump 301 is used to control the gas inside the inflation ball 302 to be collected and released into the airbag 4 through the first air pipe 303.
[0060] Finally, after use, the push plate 505 is used to control the rotation of the spherical valve 503, and through the exhaust hole inside it, the airbag 4 is connected to the outside world, so as to discharge the gas in the airbag 4. After the discharge is completed, the push plate 505 is released.
