Description

Technical Field

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

[0002] A tracheal tube is a medical device used to be inserted into the trachea to establish an artificial airway and ensure the patient's respiratory function. It is usually composed of a catheter body, an air bag, an inflation tube, a one-way valve and other parts.

[0003] During the operation, the surgeon needs to insert the main body of the catheter 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, it is surrounded by the vocal cords and arytenoid cartilages, and is triangular in shape, with a narrow anterior-posterior diameter and a slightly wider left-right diameter. The diameter of the tracheal tube is close to the largest opening of the glottis, so it is easy to get stuck if you are not careful. In addition, the back of the glottis is composed of arytenoid cartilages, which are hard in texture. If the front end of the tracheal tube is not aligned with the center of the glottis, it is easy to hit the arytenoid cartilage, causing the tracheal tube to get stuck. Summary of the invention

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

[0005] In order to solve the above problems, the present invention adopts the following technical solutions: The embodiment of the present application provides an endotracheal tube comprising: a tube body and an actuating assembly.

[0006] 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 assembly responds to the driving source and performs an actuating action to make the first area radially approach the second area, 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 area radially moves away from the second area, and the tube body switches from the second state to the first state.

[0007] In one embodiment, when the tube body is in the first state, the portion where the first region is connected to the tube body is smoothly arranged.

[0008] In one embodiment, the actuating assembly includes: a traction rope, the distal end of which is passed around the tube body and sequentially 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.

[0009] In one embodiment, the actuation assembly further includes: a driving member, the driving member is disposed on the tube body and can slide relative to the tube body in the axial direction of the tube body, the driving member is connected to the proximal end of the traction rope and is used to pull the traction rope to make the first area radially close to the second area; And / or, the actuating assembly further comprises: a skin, wherein the skin is arranged on the outer surface of the tube body and covers the traction rope.

[0010] In one embodiment, the actuating assembly is disposed on the side wall of the tube body and close to the distal end of the tube body, the actuating assembly is an air bag, the actuating assembly is connected to an air source, and expands itself during ventilation to make the first area radially approach the second area, or the actuating assembly is a piezoelectric sheet, the actuating assembly is connected to a power source, and bends itself when energized to make the first area radially approach the second area.

[0011] In one embodiment, the tube body is further provided with a deformation notch, and the deformation notch is provided on the circumference of the port at the distal end of the tube body and is located between the first area and the second area; And / or, the tube body is further provided with a deformation groove, the deformation groove is arranged on the side wall of the tube body and close to the distal end of the tube body, and the line connecting the deformation groove and the first area is parallel to the axial direction of the tube body.

[0012] In one embodiment, the first region is provided with a first notch, and the first notch is configured to restrict the guide wire or endoscope located in the tube body from moving in a direction perpendicular to the axis of the tube body when the first region approaches the second region; And / or, the second region is provided with a second gap, and the second gap is configured so that when the first region moves closer to the second region, the guide wire or endoscope in the tube body invades the second gap.

[0013] In one embodiment, the second area is provided with a second notch, and the second notch is configured so that when the first area approaches the second area, the guide wire or endoscope in the tube body invades the second notch, and the second notch extends to the side wall of the tube body in the axial direction of the tube body.

[0014] In one embodiment, a window is provided on the side wall of the tube body, the window is connected to the interior of the tube body, and a line connecting the window and the first region is parallel to the axial direction of the tube body.

[0015] The technical solution adopted by the present invention can achieve the following beneficial effects: The endotracheal tube provided in the embodiment of the present application is connected to an actuating assembly on the tube body, and the actuating assembly is used to perform an actuating action after responding to a driving source, so that the first area of ​​the port at the distal end of the tube body, which is radially opposite to each other in the circumferential direction, is brought closer to the second area, thereby facilitating reducing the size of the port at the distal end of the tube body. When a guide wire or an endoscope is inserted into the endotracheal tube, a gap is provided between the guide wire or the endoscope and the side wall of the tube body of the endotracheal tube.

[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein 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".

[0031] The inventive concept of the present application is described here: A tracheal tube is a medical device used to be inserted into the trachea to establish an artificial airway and ensure the patient's respiratory function. It is usually composed of a catheter body, an air bag, an inflation tube, a one-way valve and other parts.

[0032] During the operation, the surgeon needs to insert the main body of the catheter 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, it is surrounded by the vocal cords and arytenoid cartilages, and is triangular in shape, with a narrow anterior-posterior diameter and a slightly wider left-right diameter. The diameter of the tracheal tube is close to the maximum opening of the glottis, so it is easy to get stuck if you are not careful. In addition, the back of the glottis is composed of arytenoid cartilages, which are hard in texture. If the front end of the tracheal tube is not aligned with the center of the glottis, it is easy to hit the arytenoid cartilage, causing the tracheal tube to get stuck. Especially for patients with difficult airways, the exposure of the glottis is very small, which makes it easier for the organ catheter to get stuck.

[0033] The inventors have found that when the operator is intubating the tracheal tube and 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 of the tracheal tube and the glottis. However, these operations still make it difficult to insert the tracheal tube into the trachea, and the above operations will cause varying degrees of damage to the patient's tissues.

[0034] Based on this, the inventor provides a tracheal tube, which has an actuating assembly connected to the tube body, and uses the actuating assembly to pull a first area on the port at the distal end of the tube body, and makes the first area move closer to a second area arranged oppositely in its radial direction, so that the size of the port at the distal end of the tube body can be reduced, which can facilitate the intubation of the tracheal tube.

[0035] The following is combined with Figures 1 to 10 , a tracheal tube 1 provided in the present application is described in detail through specific embodiments and application scenarios.

[0036] Please also see 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 assembly 20, wherein the actuating assembly 20 may be connected to the tube body 10 and may be used to change the shape of a port at the distal end of the tube body 10.

[0037] Specifically, in the present embodiment, the port at the distal end of the tube body 10 has a first region 110 and a second region 120 which are relatively arranged in the radial direction on the circumference. The embodiment of the present application does not set the specific shape and structure of the tube body 10. 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 to say, in this embodiment, one of the first region 110 and the second region 120 is arranged farther away from the proximal end of the tube body 10 than the other. For the convenience of description, the following description will be taken as an example in which the first region 110 is farther away from the proximal end of the tube body 10 than the second region 120.

[0038] It should be noted that, in the present embodiment, as the first region 110 approaches the second region 120, the shape of the first region 110 changes, and the port at the distal end of the tube body 10 is squeezed and becomes flat, which can help reduce the size of the port at the distal end of the tube body 10 and facilitate the insertion of the tube body 10 into the trachea.

[0039] In this embodiment, the tube body 10 can have a first state and a second state, wherein the first state is an initial state, that is, when the tube body 10 is in the first state, the tube body 10 is not acted upon by external forces, and at this time, the distal end of the tube body 10 can be set to a traditional circular radial cross section. When the tube body 10 is subjected to external forces from a driving source, the first region 110 of the tube body 10 moves closer to the second region 120, and at this time, the tube body 10 enters the second state. When the external forces from the driving source on the tube body 10 disappear, the first region 110 recovers its deformation and moves away from the second region 120, and the tube body 10 switches from the second state to the first state.

[0040] Furthermore, in some embodiments, when the tube body 10 is in the first state, the portion 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 arranged as a straight surface, which can facilitate the operator to control the movement of the tube body 10 in the natural channel of the human body.

[0041] Also, see Figure 1-Figure 4 In some embodiments, the tube body 10 may also be provided with a deformation notch 130. The deformation notch 130 may be provided in the axial direction of the port at the distal end of the tube body 10 and between the first region 110 and the second region 120. The above-mentioned deformation notch 130 may allow the first region 110 to have sufficient deformation space in the process of approaching the second region 120, thereby avoiding axial squeezing of the distal port of the tube body 10 in the process of the first region 110 approaching the second region 120, thereby causing the maximum size of the port at the distal end of the tube body 10 to increase, and at the same time, it can also make the process of the first region 110 approaching the second region 120 smoother.

[0042] 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 to a V-shaped notch. In other embodiments, the deformation notch 130 can also be set to a semicircular or elliptical notch, etc., which can be set according to actual conditions.

[0043] See also Figure 5It can be understood that, in some embodiments, the tube body 10 can also be provided with a deformation groove 140, which 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 location, thereby making it easier for the tube body 10 to bend and deform at this location. In a preferred embodiment, the line connecting the deformation groove 140 and the first area 110 can be parallel to the axial direction of the tube body 10, so that the first area 110 can bend more smoothly in the process of approaching the second area 120.

[0044] Please also see Figure 6 and Figure 7 In some embodiments, the first region 110 may be provided with a first notch 111, and the first notch 111 may be configured to restrict the guidewire or endoscope located in the tube body 10 from moving in the axial direction perpendicular to the tube body 10 when the first region 110 approaches the second region 120. It is understandable that when the first region 110 approaches the second region 120, the guidewire or endoscope located in the tube body 10 may be embedded in the first notch 111, so that the position of the guidewire 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, thereby facilitating the operator to control the tracheal tube 1 and the guidewire or endoscope to be inserted into the patient's trachea synchronously. In addition, since the guide wire or endoscope located in the tube body 10 can be embedded in 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, the radial size of the distal end of the tube body 10 can be reduced, thereby reducing the possibility of the operator getting stuck during the intubation process.

[0045] Please also see Figure 8 and Fig. 9 It can be understood that, in other embodiments, the second region 120 can be provided with a second notch 121, and the second notch 121 can be configured so that when the first region 110 moves closer to the second region 120, the guide wire or endoscope in the tube body 10 invades the second notch 121. Similarly, this can reduce the radial dimension of the distal end of the tube body 10, thereby reducing the possibility of the operator getting stuck during the intubation process.

[0046] Furthermore, 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 the guide wire or endoscope located in the tube body 10 can invade deeper into the side wall of the tube body 10 in the radial direction of the tube body 10, and in this embodiment, the side wall of the tube body 10 can be set to a partially missing structure so that the guide wire or endoscope located in the tube body 10 can completely invade the side wall of the tube body 10, which can further reduce the radial size of the distal end of the tube body 10, thereby reducing the possibility of the operator getting stuck during the intubation process.

[0047] Also, see Fig.10 In some other embodiments, a window 150 may be provided on the side wall of the tube body 10, and the window 150 may be connected to the interior of the tube body 10. It is understandable that when the first area 110 is radially close to the second area 120, the port size at the far end of the tube body 10 may be too small, which may make it difficult for the patient to exchange gas. Therefore, the window 150 is provided on the side wall of the tube body 10 so that the patient can breathe normally during the operation. The embodiment of the present application does not limit the specific position of the window 150. For example, in one embodiment, the line connecting the window 150 and the first area 110 may be parallel to the axial direction of the tube body 10, which can also facilitate the deformation of the first area 110.

[0048] Please refer again Figure 1 , Figure 2 and Figure 4 The actuating assembly 20 can be connected to the tube body 10, and the actuating assembly 20 can be used to connect to the driving source, and to respond to the driving source to make an actuating action so that the first area 110 moves closer to the second area 120. It should be noted that the embodiment of the present application does not limit the specific form and structure of the actuating assembly 20, nor does it limit the specific form of the driving source. For example, in some embodiments, the actuating assembly 20 can be an air bag or a piezoelectric sheet, etc. In this case, the actuating assembly 20 can be arranged on the side wall of the tube body 10 and close to the distal end of the tube body 10.

[0049] For details, please refer to Figure 2 When the actuating assembly 20 is an air bag, the actuating assembly 20 can be connected to an external air source, in which case the external air source is a driving source, and the actuating assembly 20 can expand itself during ventilation to make the first area 110 radially close to the second area 120. It can be understood that the external air source can be provided by a syringe connected to the air connector of the tracheal tube 1.

[0050] When the actuator assembly 20 is a piezoelectric sheet, the actuator assembly 20 can be connected to an external power source, in which case the external power source is a driving source, and the actuator assembly 20 can bend itself when powered on, so that the first area 110 is radially close to the second area 120. It can be understood that the external power source can be provided by an external circuit or a battery connected to a plug of the endotracheal tube 1.

[0051] In addition, please refer to Figure 1 and Figure 4 In other embodiments, the actuating assembly 20 may further include: a traction rope 210, the distal end of the traction rope 210 is passed around the tube body 10 and passes through the second area 120 and the first area 110 in sequence to form a loop, and the traction rope 210 extends from the second area 120 to the proximal end of the tube body 10, so that when the distal end of the traction rope 210 is subjected to an external force and the proximal end of the traction rope 210 is pulled, the first area 110 at the port of the distal end of the tube body 10 can move closer to the second area 120.

[0052] Furthermore, in one embodiment, the actuating assembly 20 may also include: a driving member 220, which may be disposed on the tube body 10 and may slide relative to the tube body 10 in the axial direction of the tube body 10, and the driving member 220 may be connected to the proximal end of the traction rope 210 and used to pull the traction rope 210 to make the first area 110 radially approach the second area 120. The above-mentioned setting of the driving member 220 can facilitate the operator to control and then pull or release the traction rope 210. It should be noted that the embodiment of the present application does not limit the specific form of the driving member 220. For example, in another embodiment, 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, and the driving member 220 can also have a first extension portion, which can be connected to the sleeve portion and extend along the visual direction of the tube body 10, so that the operator can further overlap the finger on the driving member 220, thereby facilitating the operator to control and then pull or release the traction rope 210, and the driving member 220 can also have a second extension portion, which can be connected to the first extension portion and extend toward the distal end of the tube body 10, so that it is convenient to limit 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 structure, which can be specifically set according to actual conditions.

[0053] As mentioned above, when the actuating assembly 20 adopts a combination of a traction rope 210 and a driving member 220, the window 150 can also be set in the first area 110, and closer to the proximal end of the tube body 10 than the first area 110, so that the first area 110 or one side of the first area 110 has a weak portion, which makes it easier for the first area 110 to deform under the action of the actuating assembly 20 and move closer to the second area 120.

[0054] Also, please read Figure 4 In some embodiments, the actuator assembly 20 may further include: a skin 230, which may be disposed on the outer surface of the tube body 10 and cover the traction rope 210, so that the traction rope 210 may be prevented from contacting with secretions in the human body and causing the traction rope 210 to be corroded, etc., which is beneficial to improving the service life of the traction rope 210. It should be noted that the embodiment of the present application does not limit the specific form and structure of the skin 230. For example, in one embodiment, the skin 230 may be a sheet-like structure and may be bonded to the outer surface of the tube body 10, so that it is more convenient to assemble the tracheal tube 1. In other embodiments, the skin 230 may also be a tubular structure, and the traction rope 210 may be disposed in the skin 230, so that the possibility of the traction rope 210 being contaminated by the outside world may be further reduced. The specific form of the skin 230 may be set according to the actual situation and is not limited here.

[0055] In summary, the endotracheal tube 1 provided in the embodiment of the present application is connected to the actuating assembly 20 on the tube body 10, and the actuating assembly 20 is used to perform an actuating action after responding to a driving source, so that the first area 110 of the port at the distal end of the tube body 10, which is radially opposite to each other in the circumferential direction, is brought closer to the second area 120, thereby facilitating the reduction of the size of the port at the distal end of the tube body 10. In this way, the phenomenon that the endotracheal tube 1 abuts against the glottis during intubation and causes difficulty in intubation can be avoided or reduced, and the problem in the prior art that the endotracheal tube 1 is stuck at the glottis and is difficult to enter the trachea due to glottis stenosis during intubation is solved.

[0056] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0057] In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved.
