Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a tracheal catheter. Background Art

[0002] A tracheal catheter is a medical device used to insert into the trachea to establish an artificial airway and ensure the patient's breathing function. It usually consists of a catheter body, an airbag, an inflation tube, a one-way valve, and other parts.

[0003] During the operation, the operator needs to insert the catheter body into the patient's body and extend it into the trachea after passing through the glottis of the patient. Since the glottis is the narrowest part of the larynx, surrounded by the vocal cords and arytenoid cartilages, shaped like a triangle, with a relatively narrow anteroposterior diameter and a slightly wider left-right diameter, and the diameter of the tracheal catheter is close to the maximum opening of the glottis, it is easy to get stuck if not careful. Moreover, the posterior part of the glottis is composed of arytenoid cartilages with a relatively hard texture. If the front end of the tracheal catheter fails to align with the center of the glottis, it is likely to hit the arytenoid cartilage, resulting in the tracheal catheter getting stuck. Summary of the Invention

[0004] The present invention discloses a tracheal catheter to at least partially improve the above technical problems.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] An embodiment of the present application provides a tracheal catheter including: a tube body and an actuating component. The circumferential direction of the port at the distal end of the tube body has a first region and a second region that are oppositely arranged in the radial direction. The actuating component is connected to the tube body, and the actuating component is used to connect to a driving source and is used to make an actuating action in response to the driving source so that the first region radially approaches the second region.

[0007] In one embodiment, the tube body has a first state and a second state. When the tube body is acted upon by a power source, the actuating component makes an actuating action in response to the driving source so that the first region radially approaches the second region, and the tube body switches from the first state to the second state; when the power source acting on the tube body disappears, the first region radially moves away from the second region, and the tube body switches from the second state to the first state.

[0008] In one embodiment, when the tube body is in the first state, the part where the first region is connected to the tube body is smoothly arranged.

[0009] In one embodiment, the actuating component includes: a traction rope. The distal end of the traction rope passes around the tube body and successively passes through the second region and the first region to form a loop, and extends from the second region to the proximal end of the tube body.

[0010] In one embodiment, the actuating component further includes: a driving member disposed on the tube body and slidable relative to the tube body in the axial direction of the tube body, the driving member being connected to the proximal end of the traction rope and configured to pull the traction rope to radially move the first region closer to the second region;

[0011] And / or, the actuating component further includes: a skin disposed on the outer surface of the tube body and covering the traction rope.

[0012] In one embodiment, the actuating component is disposed on the side wall of the tube body and near the distal end of the tube body, the actuating component is an airbag, the actuating component is connected to a gas source and expands itself when ventilated, so as to radially move the first region closer to the second region,

[0013] Or, the actuating component is a piezoelectric sheet, the actuating component is connected to a power source and bends itself when powered on, so as to radially move the first region closer to the second region.

[0014] In one embodiment, the tube body is further provided with a deformation notch, the deformation notch is disposed on the circumference of the port at the distal end of the tube body and located between the first region and the second region;

[0015] And / or, the tube body is further provided with a deformation groove, the deformation groove is disposed on the side wall of the tube body and near the distal end of the tube body, and the connection line between the deformation groove and the first region is parallel to the axial direction of the tube body.

[0016] In one embodiment, the first region is provided with a first notch, and the first notch is configured to limit the movement of the guide wire or endoscope located in the tube body in a direction perpendicular to the axial direction of the tube body when the first region moves closer to the second region;

[0017] And / or, the second region is provided with a second notch, and the second notch is configured to allow the guide wire or endoscope in the tube body to invade the second notch when the first region moves closer to the second region.

[0018] In one embodiment, the second region is provided with a second notch, and the second notch is configured to allow the guide wire or endoscope in the tube body to invade the second notch when the first region moves closer to the second region, and the second notch extends in the axial direction of the tube body to the side wall of the tube body.

[0019] In one embodiment, a window is provided on the side wall of the tube body, the window is in communication with the inside of the tube body, and the connection line between the window and the first region is parallel to the axial direction of the tube body.

[0020] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0021] The tracheal catheter provided by the embodiment of the present application connects an actuating component to the tube body, and uses the actuating component to perform an actuating action in response to a driving source, so that a first region radially opposite in the circumferential direction of the port at the distal end of the tube body approaches a second region, thereby facilitating the reduction of the size of the port at the distal end of the tube body. And when a guide wire or an endoscope is inserted into the tracheal catheter, there is a gap between the guide wire or the endoscope and the side wall of the tube body of the tracheal catheter. Due to the existence of this gap, when the tube body passes through the glottis, it is easy for the glottis to get stuck at the step formed by the gap. The tracheal catheter provided by the embodiment of the present application can also reduce or eliminate the above-mentioned step by the first region approaching the second region, so as to avoid or reduce the phenomenon that the tracheal catheter abuts against the glottis during intubation, resulting in difficult intubation, and solves the problem that in the prior art, the tracheal catheter is stuck at the glottis and difficult to enter the trachea due to glottis stenosis during intubation.

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0035] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0036] In each embodiment of the present application, "proximal end" and "distal end" refer to the relative distances of each component from the user in the usage environment. Among them, the end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0037] The inventive concept of the present application is described here:

[0038] A tracheal tube is a medical device used to insert into the trachea to establish an artificial airway and ensure the patient's respiratory function. It usually consists of a catheter body, an airbag, an inflation tube, a one-way valve and other parts.

[0039] During the operation, the operator needs to insert the catheter body into the patient's body and extend it into the trachea after passing through the patient's glottis. Since the glottis is the narrowest part of the larynx, surrounded by the vocal cords and arytenoid cartilages, shaped like a triangle, with a narrower anteroposterior diameter and a slightly wider left-right diameter, the diameter of the tracheal tube is close to the maximum opening of the glottis. Therefore, if not careful, it is easy to get stuck. Moreover, the posterior part of the glottis is composed of arytenoid cartilages, with a relatively hard texture. If the front end of the tracheal tube fails to align with the center of the glottis, it is easy to hit the arytenoid cartilage, resulting in the tracheal tube getting stuck. Especially for patients with difficult airways, the exposure degree of the glottis is very small, making it even more likely for the tracheal tube to get stuck.

[0040] The inventor found that during the intubation operation of the tracheal tube by the operator, when encountering the situation where the tracheal tube gets stuck, the operator usually rotates the tracheal tube or moves the tracheal tube up and down to adjust the relative position between the tracheal tube and the glottis. However, these operations still have the problem that it is difficult to insert the tracheal tube into the trachea, and the above operations will cause varying degrees of damage to the patient's tissues.

[0041] Based on this, the inventor provides a tracheal tube. An actuating component is connected to the tube body of this tracheal tube, and the actuating component is used to pull a first region on the distal port of the tube body and make the first region approach a second region oppositely arranged in its radial direction, so that the size of the distal port of the tube body can be reduced, thereby facilitating the intubation of the tracheal tube.

[0042] The following combines the attached Figures 1 to 10 , and through specific embodiments and their application scenarios, a tracheal tube 1 provided by the present application is described in detail.

[0043] Please also refer to Figure 1 and Figure 2 , an embodiment of the present application provides a tracheal tube 1, which may include: a tube body 10 and an actuating component 20. The actuating component 20 can be connected to the tube body 10 and can be used to change the shape of the distal port of the tube body 10.

[0044] Specifically, in this embodiment, on the circumference of the port at the distal end of the tube body 10, there are a first region 110 and a second region 120 which are oppositely arranged in the radial direction. The specific shape and structure of the tube body 10 are not set in the embodiments of the present application. For example, in some embodiments, the port at the distal end of the tube body 10 can be set to an inclined structure, that is, in this embodiment, one of the first region 110 and the second region 120 is set farther from the proximal end of the tube body 10 than the other. For the convenience of description, hereinafter, the case where the first region 110 is farther from the proximal end of the tube body 10 than the second region 120 will be taken as an example for description.

[0045] It should be noted that, in this embodiment, during the process of the first region 110 approaching the second region 120, the shape of the first region 110 will change, and the port at the distal end of the tube body 10 will be squeezed and thus become flattened, which is conducive to reducing the size of the port at the distal end of the tube body 10, and thus is conducive to inserting the tube body 10 into the trachea.

[0046] In this embodiment, the tube body 10 can have a first state and a second state, where the first state is the initial state, that is, when the tube body 10 is in the first state, the tube body 10 is not subjected to external force, and at this time, the distal port of the tube body 10 can be set to a conventional circular radial cross-section. When the tube body 10 is subjected to external force from a driving source, the first region 110 of the tube body 10 approaches the second region 120, and at this time, the tube body 10 enters the second state. When the external force from the driving source acting on the tube body 10 disappears, the first region 110 restores its deformation and moves away from the second region 120, and the tube body 10 switches from the second state to the first state.

[0047] Furthermore, in some embodiments, when the tube body 10 is in the first state, the part where the first region 110 is connected to the tube body 10 is smoothly arranged, that is, when the tube body 10 is in the first state, the outer surface of the tube body 10 can be set to a straight surface, which is conducive to the operator controlling the movement of the tube body 10 in the natural channel of the human body.

[0048] In addition, please also refer to Figures 1 - 4 , in some embodiments, the tube body 10 can also be provided with a deformation notch 130. The deformation notch 130 can be arranged axially at the port at the distal end of the tube body 10 and is located between the first region 110 and the second region 120. The above-mentioned deformation notch 130 can enable the first region 110 to have sufficient deformation space during the process of approaching the second region 120, avoiding axial extrusion of the port at the distal end of the tube body 10 during the process of the first region 110 approaching the second region 120, and thus causing the situation that the maximum size of the port at the distal end of the end tube body 10 increases. At the same time, it can also make the process of the first region 110 approaching the second region 120 smoother.

[0049] The embodiments of the present application do not limit the specific form of the deformation notch 130. For example, in some embodiments, the deformation notch 130 can be set as a V-shaped notch. In other embodiments, the deformation notch 130 can also be set as a semi-circular or elliptical notch, etc., which can be specifically set according to the actual situation.

[0050] Please refer to Figure 5 , it can be understood that in some embodiments, the tube body 10 can also be provided with a deformation groove 140. The deformation groove 140 can be provided on the side wall of the tube body 10 and close to the distal end of the tube body 10. The deformation groove 140 can be used to reduce the structural strength of the side wall of the tube body 10 at this place, and thus the tube body 10 can be more easily bent and deformed at this place. In a preferred embodiment, the connection line between the deformation groove 140 and the first region 110 can be parallel to the axial direction of the tube body 10, so that the first region 110 can be bent more smoothly when approaching the second region 120.

[0051] Please refer to Figure 6 and Figure 7 , in some embodiments, the first region 110 can be provided with a first notch 111. The first notch 111 can be set such that when the first region 110 approaches the second region 120, it restricts the movement of the guide wire or endoscope located in the tube body 10 in the direction perpendicular to the axial direction of the tube body 10. It can be understood that when the first region 110 approaches the second region 120, the guide wire or endoscope located in the tube body 10 can be embedded into the first notch 111, so that the position of the guide wire or endoscope located in the tube body 10 and the tube body 10 can be relatively fixed in the radial direction of the tube body 10, and thus it is convenient for the operator to control the tracheal catheter 1 to be inserted into the patient's trachea synchronously with the guide wire or endoscope. In addition, since the guide wire or endoscope located in the tube body 10 can be embedded into the first notch 111, that is, the guide wire or endoscope located in the tube body 10 can invade the side wall of the tube body 10, so that the radial dimension of the distal port of the tube body 10 can be made smaller, and thus the possibility of the operator being stuck during the intubation process can be reduced.

[0052] Please refer to Figure 8 and Figure 9 , it can be understood that in other embodiments, the second region 120 can be provided with a second notch 121. The second notch 121 can be set such that when the first region 110 approaches the second region 120, the guide wire or endoscope in the tube body 10 can invade to the second notch 121. Similarly, this can make the radial dimension of the distal port of the tube body 10 smaller, and thus the possibility of the operator being stuck during the intubation process can be reduced.

[0053] Further, in one embodiment, the second notch 121 can extend to the side wall of the tube body 10 in the axial direction of the tube body 10, so that a guide wire or an endoscope located inside the tube body 10 can penetrate deeper into the side wall of the tube body 10 in the radial direction. And in this embodiment, the side wall of the tube body 10 can be set as a partially missing structure, so that the guide wire or the endoscope located inside the tube body 10 can completely penetrate into the side wall of the tube body 10, which can further reduce the radial dimension of the distal port of the tube body 10, and then reduce the possibility that the operator is stuck during the intubation process.

[0054] In addition, please refer to Figure 10 , in some other embodiments, a window 150 can be provided on the side wall of the tube body 10, and the window 150 can communicate with the inside of the tube body 10. It can be understood that when the first region 110 radially approaches the second region 120, the port size of the distal end of the tube body 10 may be too small, resulting in difficulty for the patient to perform gas exchange. Therefore, providing the window 150 on the side wall of the tube body 10 can ensure the normal breathing of the patient during the operation. The specific position of the window 150 is not limited in the embodiments of the present application. For example, in one embodiment, the connection line between the window 150 and the first region 110 can be parallel to the axial direction of the tube body 10, which can also facilitate the deformation of the first region 110.

[0055] Please refer to again Figure 1 , Figure 2 and Figure 4 , the actuating component 20 can be connected to the tube body 10, and the actuating component 20 can be used to connect to a driving source and respond to the driving source to perform an actuating action to make the first region 110 approach the second region 120. It should be noted that the specific form and structure of the actuating component 20 are not limited in the embodiments of the present application, nor is the specific form of the driving source. For example, in some embodiments, the actuating component 20 can be an airbag or a piezoelectric sheet, etc. At this time, the actuating component 20 can be provided on the side wall of the tube body 10 and close to the distal end of the tube body 10.

[0056] Specifically, please refer to Figure 2 When the actuating component 20 is an airbag, the actuating component 20 can be connected to an external air source. At this time, the external air source is the driving source, and the actuating component 20 can expand itself when ventilated, so that the first region 110 approaches the second region 120 radially. It can be understood that the external air source can be provided by a syringe connected to the air connector of the tracheal catheter 1.

[0057] When the actuating component 20 is a piezoelectric sheet, the actuating component 20 can be connected to an external power source. At this time, the external power source is the driving source, and the actuating component 20 can bend itself when powered on, so that the first region 110 radially approaches the second region 120. It can be understood that the external power source can be provided by an external circuit connected to the plug of the tracheal catheter 1 or a battery.

[0058] In addition, please also refer to Figure 1 and Figure 4 In some other embodiments, the actuating component 20 may further include: a traction rope 210. The distal end of the traction rope 210 passes through the tube body 10 in a loop and sequentially passes through the second region 120 and the first region 110, and the traction rope 210 extends from the second region 120 towards the proximal end of the tube body 10. When an external force acts on the distal end of the traction rope 210 to pull the proximal end of the traction rope 210, the first region 110 at the distal end port of the tube body 10 can approach the second region 120.

[0059] Furthermore, in one embodiment, the actuating component 20 may further include: a driving member 220. The driving member 220 can be disposed on the tube body 10 and can slide relative to the tube body 10 in the axial direction of the tube body 10. The driving member 220 can be connected to the proximal end of the traction rope 210 and is used to pull the traction rope 210 so that the first region 110 radially approaches the second region 120. The arrangement of the above-mentioned driving member 220 can facilitate the operator to manipulate and then pull or release the traction rope 210. It should be noted that the specific form of the driving member 220 is not limited in the embodiments of the present application. For example, in some embodiments, the driving member 220 can be a sleeve structure similar to a T shape. Specifically, the driving member 220 can have a sleeve portion, and the sleeve portion is slidably sleeved on the outer surface of the tube body 10. The driving member 220 can also have a first extension portion, and the first extension portion can be connected to the sleeve portion and extend along the longitudinal direction of the tube body 10. This can further enable the operator to place a finger on the driving member 220, thereby facilitating the operator to manipulate and then pull or release the traction rope 210. The driving member 220 can also have a second extension portion, and the second extension portion can be connected to the first extension portion and extend towards the distal end of the tube body 10. This can facilitate restricting the operator's finger and avoid or reduce the situation where the operator's finger slips off the first extension portion. In some other embodiments, the driving member 220 can adopt other forms of structures, which can be specifically set according to actual situations.

[0060] As described above, when the actuating component 20 adopts the combination of the traction rope 210 and the driving member 220, the window 150 can also be arranged in the first area 110 and is closer to the proximal end of the tube body 10 than the first area 110. This can make one side of the first area 110 or the first area 110 have a weak part, so that the first area 110 can be deformed under the action of the actuating component 20 and move closer to the second area 120.

[0061] In addition, please continue to refer to Figure 4 , in some embodiments, the actuating component 20 may further include: a skin 230, which can be arranged on the outer surface of the tube body 10 and cover the traction rope 210. This can prevent the traction rope 210 from contacting the secretions in the human body and being corroded, etc., and is beneficial to improving the service life of the traction rope 210. It should be noted that the specific form and structure of the skin 230 are not limited in the embodiments of the present application. For example, in one embodiment, the skin 230 may be a sheet structure and can be adhered to the outer surface of the tube body 10, which is more convenient for assembling the tracheal catheter 1. In some other embodiments, the skin 230 may also be a tubular structure, and the traction rope 210 may be arranged inside the skin 230, which can further reduce the possibility of the traction rope 210 being contaminated by the outside. The specific form of the skin 230 can be set according to the actual situation and is not limited here.

[0062] In summary, for the tracheal catheter 1 provided by the embodiments of the present application, by connecting the actuating component 20 to the tube body 10 and using the actuating component 20 to perform an actuating action in response to the drive source, the first area 110 that is radially opposite in the circumferential direction of the port at the distal end of the tube body 10 moves closer to the second area 120, which can facilitate reducing the size of the port at the distal end of the tube body 10. This can avoid or reduce the phenomenon that the tracheal catheter 1 abuts against the glottis during intubation and causes difficulty in intubation, and solves the problem that the tracheal catheter 1 gets stuck at the glottis and is difficult to enter the trachea due to glottis stenosis during intubation in the prior art.
