Description

Technical Field

[0001] The invention relates to the technical field of endotracheal intubation, and in particular to an intraoperative monitoring endotracheal intubation. Background Art

[0002] A tracheal tube is a medical device used during surgery and to establish an artificial airway in critically ill patients. It is mainly used to provide ventilation and oxygen supply, respiratory suction to prevent aspiration, maintain airway patency, and provide effective assisted breathing to ensure effective airway ventilation for patients. When in use, the mouth is opened with a mouth expander or laryngoscope, and then the tracheal tube is inserted through the glottis into the trachea. Usually, a tool is placed on the lips to prevent the tube from being bitten flat by the patient, and tape is used to fix the exposed end of the tube to the patient's lips.

[0003] China Patent Network has published a patent with the publication number: CN103239786A, which is called a tracheal tube holder, including a baffle and a grooved channel. The baffle is made of hard material, and the grooved channel is made of elastic material. A protruding bite portion is provided in the middle of the baffle, and the shape of the bite portion matches the shape of the upper end of the grooved channel. The upper end of the grooved channel is wrapped and fixedly connected to the bite portion, and the composite bite portion is hard inside and soft outside. The bite portion of the tracheal tube holder is hard inside and soft outside. The internal PC material has sufficient hardness to prevent the channel from being bitten flat, and the external TPE material has sufficient softness to protect the patient's teeth.

[0004] When the above-mentioned tracheal tube is in use, the tube is only material-changed in the oral cavity to prevent it from being bitten and closed. During use, the staff still needs to fix the tube with tape to prevent displacement. The fixing method is not comfortable, and when the tube is connected to other tubes, the increase in weight can easily cause the tube to shake and displace. If the tube is accidentally displaced, it cannot be detected and restored in time. Summary of the invention

[0026] In order to make the above-mentioned objects, 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.

[0027] 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.

[0028] 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.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, 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.

[0030] Example 1 Reference Figure 1 - Figure 6, which is the first embodiment of the present invention, and this embodiment provides an intraoperative monitoring endotracheal intubation, including a cannula 1 and a secondary tube 11. An oral fixation ring 2 is installed on the outer wall of the cannula 1. The oral fixation ring 2 is placed at the cannula 1 and the patient's pressing position to prevent the patient from biting the cannula 1 flat and causing suffocation. Two groups of sliding rods 21 are installed on the outer wall of the oral fixation ring 2. A touch plate 22 is installed at one end of the sliding rod 21. The touch plate 22 can move on the sliding rod 21, so that different patients can bite on the touch plate 22 comfortably. A transmission component 23 is installed at one end of the sliding rod 21. When the patient's lips touch the touch plate 22, its transmission component can move. A first fixing rod 24 is installed on the inner wall of the oral fixation ring 2. The first fixing rod 24 is installed on the inner wall of the oral fixation ring 2. One end of a fixing rod 24 extends out of the inner wall of the oral fixing ring 2, and a first fixing plate 241 is installed at one end of the first fixing rod 24. The first fixing plate 241 is an arc-shaped plate that can match the outer diameter of the cannula 1. After the patient's cannula 1 is completed and the expander is removed, the lips and teeth are naturally closed. At this time, the touch plate 22 is pressed to drive the sliding rod 21 to move, and the sliding rod 21 gradually touches the first fixing plate 241 on the first fixing rod 24, so that the first fixing rod 24 gradually and firmly fits on the cannula 1, which prevents the cannula 1 from displacement, and the initial diameters of the sliding rod 21 and the touch plate 22 are larger than the size of the lips of an average person, so that when the touch plate 22 is inserted into the oral cavity, it needs to be slightly pressed.

[0031] Furthermore, a lip support ring 25 is installed on the outer wall of the cannula 1, a support mask 251 is installed on the bottom of the lip support ring 25, a fixing spring 252 is installed on the inner wall of the lip support ring 25, a second fixing rod 253 is installed at one end of the fixing spring 252, and a second fixing plate 254 is installed at one end of the second fixing rod 253. The oral fixing ring 2 is first positioned between the patient's teeth, and the movable connection between the rotating rod and the oral fixing ring 2 makes the lip support ring 25 have a displacement gap, so that the support mask 251 can contact the patient's lips. At this time, the lip support ring 25 and the oral fixing ring 2 fix the cannula 1 at the same time, and the weight of the cannula 1 can be evenly distributed, reducing the possibility of displacement of the cannula 1.

[0032] Furthermore, the top end of the rotating shaft 233 extends into the interior of the lip support ring 25 and is fixedly connected to the inner wall of the lip support ring 25 through a bearing, and the upper elliptical block 235 is located on one side of the second fixed rod 253. There is a movable gap between the rotating shaft 233 and the oral fixed ring 2 to adapt to different patients. The lower elliptical block 236 is located on one side of the first fixed rod 24.

[0033] Furthermore, the stopper 234 is movably connected to the gear 237, and the gear 237 is fixed to the inner top wall of the oral retainer ring 2 through a sleeve and a bearing, so that when the stopper 234 moves up and down with the rotating rod, the gear 237 will not be offset.

[0034] Furthermore, the transmission assembly 23 includes a tooth plate 231 installed at one end of the sliding rod 21, a spring rod 232 is installed on the inner wall of the tooth plate 231, a rotating shaft 233 is movably installed inside the oral fixing ring 2, a limiting member 234 is installed on the outer wall of the rotating shaft 233, an upper elliptical block 235 is installed on the top of the rotating shaft 233, a lower elliptical block 236 is installed on the bottom of the rotating shaft 233, and a gear 237 is installed on the outer wall of the limiting member 234. When the touch plate 22 is pressed to drive the sliding rod 21 to move, the sliding rod 21 drives the tooth plate 231 to move, and the movement of the tooth plate 231 drives the rotating shaft 233 The upper elliptical block 235 rotates and moves, and the upper elliptical block 235 rotates and contacts and presses to drive the second fixing rod 253 on the second fixing plate 254 to move, so that the second fixing plate 254 gradually fits and fixes the outer wall of the cannula 1, and finally the oral fixing ring 2 fixes the cannula 1 inside the mouth, and the supporting mask 251 is supported on the edge of the patient's lips, and the lip supporting ring 25 fixes the cannula 1. At this time, if the outer end of the cannula 1 is connected to other tubes, its weight can be shared by the lip supporting ring 25 and the supporting mask 251, which effectively reduces the possibility of displacement of the cannula 1.

[0035] Operation process: when intubating 1, the patient's oral cavity is opened by the expander or laryngoscope, at this time, the touch plate 22 is pressed and placed between the two teeth. When the expander is released, the touch plate 22 is pressed and drives the sliding bar 21 to move, and the sliding bar 21 drives the tooth plate 231 to move. The movement of the tooth plate 231 drives the rotating shaft 233 to rotate, and the rotation of the rotating shaft 233 drives the upper elliptical block 235 to rotate and move. The upper elliptical block 235 rotates and contacts the second fixing rod 253 on the second fixing plate 254, so that the second fixing plate 254 approaches the intubation tube 1 and fits and fixes it. At this time, the support mouth mask 251 is supported on the edge of the patient's lips, and the lip support ring 25 fixes the intubation tube 1, so that when the top side port of the intubation tube 1 is plugged into other tube bodies, its weight is evenly distributed on the lips, reducing the possibility of displacement of the intubation tube 1, and the movement of the tooth plate 231 causes the pressure applied by the spring rod 232 to the first fixing plate 241 to gradually increase, and finally the first fixing plate 241 fixes the intubation tube 1.

[0036] Example 2 Reference Figure 6 and Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a fitting wheel 26 is installed on the inner wall of the oral fixing ring 2, a belt member 261 is installed on the shaft of the fitting wheel 26, an air cavity 262 is installed on the inner bottom wall of the oral fixing ring 2, a trigger block 263 is installed on the top of the air cavity 262, and a whistle body 264 is installed on the outer wall of one side of the trigger block 263. The fitting wheel 26 is in contact with the cannula 1, and the cannula 1 moves, and the fitting wheel 26 also rotates accordingly. If the trigger block 263 is in an open state, the gas in the air cavity 262 can flow out through the whistle body 264, thereby making a sound.

[0037] Furthermore, an opening 2631 is provided on the inner wall of the trigger block 263, a sealing block 2632 is movably mounted on the inner wall of the opening 2631, a rotating disk 2633 is mounted on the top side of the sealing block 2632, the rotating disk 2633 and the sealing block 2632 are movably connected via a pull rod 2634, a bending shaft 2635 is mounted on the inner wall of the trigger block 263, and the bending shaft 2635 is connected to the belt member 261, a touch-pressure rod 2636 is mounted on one side of the bending shaft 2635, and the touch-pressure rod 2636 extends to the lower elliptical block 23 6 side, when the rotating shaft 233 rotates, the lower elliptical block 236 can contact and press the contact and pressure rod 2636 to move, and the contact and pressure rod 2636 rotates and moves the bending shaft 2635, so that the bending shaft 2635 is connected to the rotating disk 2633. At this time, if the cannula 1 is displaced, the fitting wheel 26, the belt member 261, the bending shaft 2635 and the rotating disk 2633 move successively, so that the rotating disk 2633 finally pulls the sealing block 2632, thereby opening the opening 2631, and the whistle body 264 can make a sound; When the bending shaft 2635 is in contact with the shaft of the rotating disk 2633, if the bending shaft 2635 is transmitted, it can drive the rotating disk 2633 to rotate. The initial position of the pull rod 2634 is located at the lowest side of the rotating disk 2633, so that no matter how the rotating disk 2633 rotates, the sealing block 2632 is pulled upward, and a torsion spring is installed at one end of the rotating disk 2633. After the rotating disk 2633 is displaced, it can be gradually restored by the torsion spring, and then the fitting wheel 26 can also be reversed to drive the cannula 1 to move back.

[0038] The rest of the structure is the same as that of Example 1.

[0039] Operation process: After the positioning of the oral fixation ring 2 is completed and the patient's lips touch the rotating shaft 233 to rotate, the lower elliptical block 236 of the rotating shaft 233 drives the touch-pressure rod 2636 to move. When the touch-pressure rod 2636 moves to its position, its bent rotating shaft 2635 is connected with the rotating disk 2633. Since the first fixing plate 241 and the second fixing plate 251 are fixed to the cannula 1 only by friction, they can only effectively resist the normal force on the cannula 1, so that the cannula 1 does not move, and the patient is subconsciously uncomfortable. When the cannula 1 is pulled or pressed, or other unexpected factors generate a large force, the cannula 1 is inevitably displaced, and the fitting wheel 26 transmits the displacement action to the rotating disk 2633 through the belt. The rotating disk 2633 rotates to drive the sealing block 2632 to open the opening 2631. At this time, the gas in the air cavity 262 flows out through the whistle body 264, thereby making a sound, and the torsion spring can restore the rotating disk 2633 after rotation, thereby restoring the cannula 1 and reducing the impact of the displacement of the cannula 1.

[0040] Working principle: When in use, the cannula 1 is passed through the lip support ring 25 and the oral fixation ring 2 in sequence, and then the cannula 1 is inserted into the trachea. After the cannula 1 is positioned, the lip support ring 25 and the oral fixation ring 2 are moved, and the oral fixation ring 2 is moved to between the teeth. Then the bottom side of the support mask 251 is fitted with the outside of the mouth. At this time, the expander is released, and the patient's lips are naturally closed. At this time, the closing action drives the touch plate 22 to move, and the movement of the touch plate 22 causes the rotating shaft 233 to rotate. The upper elliptical block 235 drives the second fixing plate 254 to move toward the outer wall of one side of the cannula 1, and the second fixing plate 254 is clamped and fixed on the cannula 1, so that the lip support ring 25 is fixedly connected to the cannula 1, and the spring rod 232 moves to press and fix the first fixing plate 241 on the cannula 1. At this time, the cannula 1 can be fixed without the need for binding tape. There is no need to worry about the cannula 1 being bitten and closed, and the rotation of the lower elliptical block 236 drives the touch-pressure rod 2636 to move toward the side of the rotating disk 2633, so that the bent shaft 2635 gradually approaches the side of the rotating disk 2633, and finally the bent shaft 2635 and the rotating disk 2633 are driven to engage, and the rotating disk 2633 shaft is installed with a torsion spring. If the cannula 1 is displaced, the fitting wheel 26 transmits the displacement action to the rotating disk 2633 through the belt part 261, and the rotating disk 2633 rotates to drive the sealing block 2632 to open the opening 2631. At this time, the gas in the air cavity 262 flows out through the whistle body 264, and then makes a sound, which can be detected by the staff in time, and the torsion spring can apply a restoring force to the rotating disk 2633, which can gradually restore the displaced cannula 1, thereby reducing the adverse medical events caused by the displacement of the cannula 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
