Description

Technical Field

[0001] The present invention relates to the technical field of intelligent regulation of temperature and humidity tracheal cannula, and in particular to an intelligent temperature and humidity adjustable tracheal cannula. Background Art

[0002] A warm and moist tracheal tube is a medical device used in patients with tracheotomy to maintain airway moisture and temperature. After tracheotomy, the patient loses the nasal cavity's ability to warm and moisten the inhaled air, such as in the treatment of patients with nasopharyngeal carcinoma.

[0003] After searching: an easily adjustable endotracheal tube, the publication number is CN113827832A. When performing endotracheal intubation, the nickel-titanium alloy mesh frame is rotated by hand, and the adjusting piece rotates on the threaded segment. Since the spiral directions of the two threaded segments are opposite, when the two adjusting pieces are rotated at the same time, the moving directions in the intubation direction are opposite. When rotating in one direction, the two adjusting pieces are closed, and when rotating in the other direction, the two adjusting pieces are separated. When the adjusting pieces are closed, the nickel-titanium alloy mesh frame is squeezed and expanded, and the diameter becomes larger. When the adjusting pieces are separated, the nickel-titanium alloy mesh frame is stretched and the diameter becomes smaller. Therefore, the diameter can be adjusted by rotating the nickel-titanium alloy mesh frame, so that it can be adjusted according to the throat size of different patients. The scope of use is wider, and the use effect of each patient can meet the requirements. The elastic coating can change with the expansion and contraction of the nickel-titanium alloy mesh frame. The elastic coating is in contact with the patient's throat to prevent the throat tissue from directly contacting the nickel-titanium alloy mesh frame, causing the tissue to adhere to the mesh and be unable to be separated, thereby injuring the patient.

[0004] However, in actual use, the prior art needs to be performed in vitro because the nickel-titanium alloy mesh frame needs to be rotated manually. However, when the nickel-titanium alloy mesh frame is rotated in vitro, the diameter of the nickel-titanium alloy mesh frame is equal to the inner diameter of the patient's throat. Therefore, before the trachea is inserted into the throat and reaches the designated position, the elastic coating on the surface of the nickel-titanium alloy mesh frame will contact and rub against other positions of the inner wall of the patient's throat, thereby increasing the patient's discomfort and, in severe cases, may cause scratches and damage to other parts of the patient's throat.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-10 , the present invention provides a technical solution:

[0035] An intelligent adjustable temperature and humidity tracheal cannula comprises a tracheal cannula 1, a tracheal cannula 1, a fixing seat 5 is fixedly connected to the end of the tracheal cannula 1, and an electric heating wire 4 extending along the central axis of the tracheal cannula 1 is fixedly connected to the fixing seat 5. The electric heating wire 4 is energized and heated to keep the entire space in the tracheal cannula 1 in a constant temperature state, that is, to ensure that the added moisture can be kept warm throughout the entire process when passing through the tracheal cannula 1, and the moisture in the tracheal cannula 1 is added in an existing manner, for example, an additional pipe is connected to the head of the tracheal cannula 1 for pouring The fixed seat 5 is connected and fixed to the end of the electric heating wire 4 by a spiral or clamping method to ensure that the end of the electric heating wire 4 will not be separated from the end of the tracheal cannula 1 during the bending process of the tracheal cannula 1. A plurality of groups of bases are fixedly connected to the surface of the electric heating wire 4. Each group of bases consists of a fixed ring 10 and a rotating ring 6 rotatably connected to the side of the fixed ring 10. Each group of bases is provided with a diameter adjustment mechanism for adjusting the diameter of the tracheal cannula 1, and a set of curvature adjustment mechanisms for adjusting the curvature of the tracheal cannula are provided between two adjacent groups of bases.

[0036] Embodiment 1: The diameter adjustment mechanism includes a plurality of spring rods 11 distributed in a circular array and respectively fixed on the outer side walls of the rotating ring 6 and the fixed ring 10. The positions and quantities of the plurality of spring rods 11 on the outer sides of the rotating ring 6 and the fixed ring 10 correspond one to one. The telescopic ends of the spring rods 11 on the fixed ring 10 extend to both sides and expand into a columnar shape. The telescopic ends of the spring rods 11 on the rotating ring 6 are fixedly connected with a stepping block 13. The diameter adjustment mechanism also includes a plurality of holders 12 integrally formed with the inner wall of the tracheal cannula 1. The positions of the plurality of holders 12 and the columnar protrusions of the telescopic ends of the plurality of spring rods 11 correspond one to one, and the columnar protrusions of the telescopic ends of the spring rods 11 overlap the holders 12 at the corresponding positions, and the stepping blocks 13 overlap the side faces and bottom edges of the holders 12 at the corresponding positions.

[0037] Specifically, the purpose of setting the diameter adjustment mechanism is to make adjustments according to the actual situation of the patient's trachea. Therefore, the tracheal cannula 1 used in the present invention is made of elastic material, which is convenient for expansion and contraction. In addition, by adjusting the diameter of a certain section of the tracheal cannula 1 in stages, the section of the tracheal cannula 1 can be prevented from contacting the patient's trachea or throat, avoiding contact with the damaged position of the trachea or throat, and affecting subsequent treatment. In addition, by adjusting the diameter of the tracheal cannula 1 as a whole, so that its diameter is smaller than the diameter of the patient's trachea or throat, it can be ensured that when the tracheal cannula 1 is inserted, the outer wall of the tracheal cannula 1 is prevented from contacting and rubbing with the patient's trachea or throat during insertion or withdrawal, affecting the patient's stress response or causing discomfort to the patient. During actual adjustment, the electric heating wire 4 and several groups of bases arranged on its surface are first placed in the tracheal cannula 1 as a whole. When the tracheal tube 1 is inserted into the base 1, the cylindrical protrusion at the telescopic end of the spring rod 11 on the fixing ring 10 is misaligned with the holder 12 on the inner wall of the tracheal tube 1 until the relative distance between the corresponding holder 12 and the cylindrical protrusion is equal. Then the electric heating wire 4 is rotated to realize the simultaneous rotation of the base, thereby realizing the alignment of the cylindrical protrusion at the telescopic end of the fixing ring 10 in the base with the holder 12. Then the electric heating wire 4 is pulled to realize the insertion of the cylindrical protrusion at the telescopic end of the spring rod 11 on the fixing ring 10 in the base into the corresponding holder 12 under the action of traction force. Then the relative position of the electric heating wire 4 and the fixing seat 5 is fixed. When the diameter of a certain section of the tracheal tube 1 needs to be adjusted, it is only necessary to control the spring rod 11 on the fixing ring 10 near the section to contract, so that the wall of the tracheal tube 1 in the section can be pulled to contract under the overlapping action of the cylindrical protrusion and the holder 12 to realize a smaller diameter.

[0038] Embodiment 2: The fixed ring 10 is also provided with a traction mechanism for driving the retractable end of the spring rod 11 on the fixed ring 10 to retract, and the traction mechanism includes a winding drum 30 that is rotatably connected to the outer side of the fixed ring 10 and is arranged near each spring rod 11, and a traction line 15 is wound around the winding drum 30, and one end of the traction line 15 passes through the fixed ring 10 and extends in a direction parallel to the spring rod 11 until it contacts the columnar protrusion at the retractable end, and a bevel gear block 31 is fixedly connected to the end face of the winding drum 30, and the traction mechanism also includes a winding drum 30 that is rotatably connected to the outer side of the fixed ring 10 and is arranged near each spring rod 11. A bevel gear ring 23 meshing with a plurality of bevel gear blocks 31, a spur gear surface 21 is provided on the side of the bevel gear ring 23 and a ratchet surface 22 is provided on the side, a ratchet pawl 29 meshing with the ratchet surface 22 is rotatably connected to the outer side of the fixing ring 10 through a retaining spring, a meshing spur gear 27 meshing with the spur gear surface 21 is rotatably connected at the extension, an end face spur gear 28 is fixedly connected to the end face of the meshing spur gear 27, and a transmission spur gear 26 meshing with the end face spur gear 28 is also rotatably connected at the extension of the fixing ring 10;

[0039] The significance of the second embodiment is that when the diameter of the tracheal tube 1 is reduced, all the spring rods 11 on the driving and fixing rings 10 are contracted at the same time. The real-time operation is as follows: the engagement of the provided ratchet 29 with the ratchet surface 22 ensures that the ratchet surface 22 can only rotate in one direction, thereby ensuring that the bevel gear ring 23 connected to the ratchet surface 22 can only rotate in one direction. Therefore, by applying a force to the transmission spur gear 26 to rotate it, the end face spur gear 28 can be rotated under the meshing connection, and the meshing spur gear 27 can be rotated with the meshing connection under the fixed connection. The bevel gear ring 23 rotates along with the rotation of the end spur gear 28, and then the spur tooth surface 21 rotates again under the meshing connection, so that the bevel gear ring 23 can be rotated. Therefore, the bevel gear blocks 31 meshing with the bevel gear ring 23 can drive the winding reel 30 to rotate, so that the traction line 15 can be wound up, and then the traction line 15 pulls the columnar protrusion at the telescopic end of the spring rod 11 to overcome the thrust of the spring rod 11 and approach the electric heating wire 4, thereby pulling the holder 12 to move, so that the diameter of the tracheal tube 1 in the corresponding area can be reduced.

[0040] In addition: a plurality of blocks 25 are fixedly connected to the outer wall of the fixed ring 10, a plug post 14 is provided through the position corresponding to the block 25 on the outer side of the rotating ring 6, a connecting spring 24 connected to the rotating ring 6 is fixedly connected to the middle position of the plug post 14, one end of which extends to be plugged with the block 25, and the other end extends to be fixedly connected to the connecting ring 7, and an insulating block 20 for inserting into the gap between the electric heating wire 4 and the inner wall of the rotating ring 6 is fixedly connected to the inner wall of the connecting ring 7;

[0041] The purpose of the scheme here is to ensure the stability of the relative position of the electric heating wire 4 and the fixed ring 10. The specific operation is as follows: the thrust of the set connecting spring 24 is used to ensure that the plug 14 is always inserted into the block 25 on the fixed ring 10, thereby ensuring that the rotating ring 6 and the fixed ring 10 will not rotate relative to each other, and the thrust of the connecting spring 24 can also generate a pulling force on the connecting ring 7 at the other end of the plug 14, ensuring that the connecting ring 7 and the insulating block 20 on its inner wall are always inserted into the gap between the electric heating wire 4 and the rotating ring 6, that is, preventing the electric heating wire 4 from contacting the rotating ring 6 or the inner wall of the fixed ring 10, and a step block 13 is set at the telescopic end of the spring rod 11 on the rotating ring 6, which can push the step block 13 to push the telescopic end of the spring rod 11 on the rotating ring 6 to move and compress synchronously when the base 12 moves toward the direction of the electric heating wire 4.

[0042] Embodiment 3: The curvature adjustment mechanism includes a front arm 16 and a rear arm 9 fixed on both sides of a fixing ring 10, and a worm gear 19 is fixedly connected to the front arm 16 on the fixing ring 10 of one of the two adjacent groups of bases, and one end of the worm gear 19 is rotatably connected to the rear arm 9 on the fixing ring 10 of the other group of bases, and the rear arm 9 on the fixing ring 10 of the other group of bases is also rotatably connected to a worm 17 meshing with the worm gear 19, and the end face of the worm 17 is fixedly connected to a front spur gear 18;

[0043] The function of the third embodiment is to further ensure that the tracheal tube 1 is staggered and does not contact the injured part of the trachea or throat by adjusting the curvature of the tracheal tube 1, and the curvature of the tracheal tube 1 can be adjusted according to the actual situation of the trachea or throat. The specific operation is as follows: starting from the base at the end of the tracheal tube 1, a force is applied to the front spur gear 18 at a similar position to rotate it, thereby realizing the rotation of the worm 17. Under the action of meshing connection, the worm gear 19 drives the rear fixed ring 10 fixedly connected thereto to swing, so as to realize the angle adjustment between the two adjacent bases, and then the front spur gears 18 are rotated one by one from back to front, so as to realize the curvature adjustment of the distribution direction of several bases, and the curvature adjustment of the tracheal tube is realized under the traction of the spring rod 11 on the fixed ring 10 in the base.

[0044] Embodiment 4: The tracheal tube 1 is also equipped with an adjusting rod 8, one end of which is a gear columnar setting, and the extended extension of the fixing ring 10 is a hollow setting that penetrates the adjusting rod 8. The gear columnar shape at one end of the adjusting rod 8 is used to mesh with the front spur gear 18 and the transmission spur gear 26, so that the adjusting rod 8 can be inserted from the head end of the tracheal tube 1 and pass through the extension of the fixing ring 10 on several bases from front to back. When passing through the front spur gear 18 or the transmission spur gear 26, it is only necessary to rotate the adjusting rod 8 so that the gear columnar part at the front end of the adjusting rod 8 remains in meshing state with the front spur gear 18 or the transmission spur gear 26, so that the adjusting rod 8 can continue to slide conveniently, or when the gear columnar part at the front end of the adjusting rod 8 is meshed with the front spur gear 18 or the transmission spur gear 26, the adjusting rod 8 can be rotated to realize the rotation of the gear columnar part at the front end of the adjusting rod 8 under the meshing connection, so as to realize the rotation of the front spur gear 18 or the transmission spur gear 26 meshed with it. In addition, this invention The rod body of the adjusting rod 8 in the case is made of flexible material, which is convenient for the adjusting rod 8 to be inserted into the trachea or throat along with the tracheal tube 1, and the flexible material can also ensure that the adjusting rod 8 can still rotate even in a bent state, thereby ensuring that the gear columnar part at the end of the adjusting rod 8 drives the front spur gear 18 or the transmission spur gear 26 to rotate; the outer wall of the tracheal tube 1 is also provided with two inflatable bags 2, and an inflatable tube 3 is connected between the two inflatable bags 2, and the inflatable bag 2 close to the tracheal tube 1 is also provided with an inflatable tube 3 extending to the head of the tracheal tube 1. There are two inflatable bags 2, and the two inflatable bags 2 are attached to the outer wall of the tracheal tube 1 by medical glue, and the position and spacing are based on the depth to be inserted into the tracheal tube 1, and the inflatable bags are arranged to avoid the damaged part of the trachea or throat when used. After the tracheal tube 1 enters the trachea or throat by using the inflatable tube 3, the inflatable bag 2 is inflated by the inflatable tube 3 to expand and fit the inner wall of the trachea or throat, so that the tracheal tube 1 can be fixed in the trachea or throat.

[0045] The method of use and working principle of the device: Before inserting the tracheal tube 1, obtain the shape and size of the patient's trachea through X-ray, and determine the location of the patient's tracheal injury, and then prepare the tracheal tube 1:

[0046] The first step: installing the electric heating wire 4 and several bases in the tracheal cannula 1. During installation, the columnar protrusion at the telescopic end of the spring rod 11 on the fixing ring 10 and the holder 12 on the inner wall of the tracheal cannula 1 are inserted into the tracheal cannula 1 in a dislocated state until the relative distance between the corresponding sub-holder 12 and the columnar protrusion is equal, and then the electric heating wire 4 is rotated to realize the simultaneous rotation of the base, thereby realizing the alignment of the columnar protrusion at the telescopic end of the fixing ring 10 in the base with the holder 12, and then pulling the electric heating wire 4, the columnar protrusion at the telescopic end of the spring rod 11 on the fixing ring 10 in the base can be inserted into the corresponding holder 12 under the action of traction, and then the relative position of the electric heating wire 4 and the fixing seat 5 can be fixed;

[0047] The second step: insert the adjusting rod 8 into the tracheal tube 1 from the front to the back, and pass through the hollow parts where the fixed rings 10 on the bases extend. During the insertion process of the adjusting rod 8 from the front to the back, it meshes with the transmission spur gears 26 in sequence. When meshing, rotate the adjusting rod 8, and use the gear columnar part at the front end to drive the transmission spur gear 26 to rotate. Under the meshing connection, the end face spur gear 28 drives the meshing spur gear 27 to rotate, and then the spur tooth surface 21 drives the bevel gear ring 23 to rotate, and the bevel gear blocks 31 meshing with the bevel gear ring 23 drive the winding reel 30 to rotate, so that the traction line 15 can be wound, and then the traction line 15 pulls the columnar protrusion at the telescopic end of the spring rod 11 to overcome the thrust of the spring rod 11 and approach the electric heating wire 4, and then pulls the clamping seat 12 to move, so that the diameter of the tracheal tube 1 in the corresponding area becomes smaller, and so on, until the overall diameter of the tracheal tube 1 is reduced as the traction line 15 on the fixed rings 10 on all bases is wound to a minimum diameter lower than the trachea;

[0048] Step 3: Adjust the curvature of the tracheal tube 1 according to the curvature of the trachea. After the adjusting rod 8 moves to the base at the end of the tracheal tube 1, pull out the adjusting rod 8. When the gear columnar part at the end of the adjusting rod 8 meshes with the front spur gear 18, the adjusting rod 8 rotates again to rotate the front spur gear 18, thereby rotating the worm 17. Under the meshing connection, the worm gear 19 drives the rear fixing ring 10 fixedly connected thereto to swing, so as to adjust the angle between two adjacent bases. Then, the front spur gears 18 are rotated one by one from back to front, so as to adjust the curvature of the distribution direction of several bases. Under the traction of the spring rod 11 on the fixing ring 10 in the base, the curvature of the tracheal tube is adjusted.

[0049] Step 4: Install the inflatable bag 2 on the outer wall of the tracheal tube 1 in a deflated state, then pull out the adjustment rod 8, insert the tracheal tube 1 with the curvature adjusted into the patient's trachea, and use the inflatable tube 3 to inflate the inflatable bag 2, and use the inflatable bag 2 to inflate and fit the healthy position in the patient's trachea, while the damaged position in the trachea is offset from the inflatable bag 2. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
