Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a visual inspector for a tracheal cannula and an inspection method thereof. Background Art

[0002] Hidden aspiration refers to the entry of food, liquids, or secretions into the respiratory tract without obvious symptoms, which may lead to serious lung infections or other complications. Traditional tracheal tubes cannot monitor hidden aspiration in real time, making it difficult to detect and address the problem in a timely manner. Currently, during the examination of the patient's laryngeal trachea, a tracheal tube is usually required to perform ventilation and other operations on the patient's trachea. However, traditional tracheal examination methods often make it difficult to directly and clearly observe the internal conditions of the trachea. When performing tracheal examinations, doctors lack effective visualization methods and find it difficult to intuitively understand lesions, foreign bodies, and other conditions in the trachea. This makes accurate diagnosis difficult and may lead to misdiagnosis or missed diagnosis, affecting the patient's treatment effect.

[0003] If a camera is used for spying, the camera is easily contaminated by secretions, sputum, etc. during the spying process. Once the camera is contaminated, its imaging quality will be greatly reduced, resulting in the inability to obtain clear tracheal images, thereby failing to provide accurate diagnostic basis for doctors. In addition, the camera needs to be removed and flushed during the treatment process, which is very inconvenient. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantage in the prior art that the camera needs to be taken out for flushing during the processing, which is very inconvenient, and to propose a visual inspector and inspection method for tracheal tube.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A visual inspection device for a tracheal tube, comprising:

[0007] A connection box is detachably mounted on one side of the outer tube of the patient's throat, and a through hole coaxial with the outer tube is formed on one side of the connection box;

[0008] A core head is connected to the connection box via a wire, wherein a micro camera is provided in the core head, and the wire is configured to transmit an image signal collected by the camera to an external display device;

[0009] Cleaning mechanism, including:

[0010] A driving member, comprising a motor fixed in the connection box and a gear driven by the motor;

[0011] The positioning member includes a rotating disk and a brush disposed in the rotating disk, wherein the rotating disk is engaged with the gear through an outer gear ring for rotation;

[0012] A water spraying member includes a water storage cavity, a sleeve rod communicated with the water storage cavity, and a piston rod. One end of the piston rod is slidably connected to an annular groove of an eccentric ring of a rotating disk, so as to drive the piston rod to reciprocate through the rotation of the rotating disk, thereby spraying the cleaning liquid to a core head through a drain pipe.

[0013] A sealing assembly includes a sealing plate and a spring slidably arranged in a connection box. The sealing plate is linked with a mounting seat through a connecting rod to seal a through hole when the core head retracts, preventing liquid from entering an outer sleeve.

[0014] As a further improvement of the above technical solution:

[0015] The positioning member further includes:

[0016] A connecting rod, fixed in the connection box, and the mounting seat is fixed on the connecting rod;

[0017] A guiding groove is formed on the outer wall of the conducting wire, and a sliding block matched with the guiding groove is arranged in the mounting seat to limit the radial rotation of the conducting wire.

[0018] The water spraying member further includes:

[0019] A partition plate, fixed in the connection box and separating the connection box into a water storage cavity and a mounting cavity;

[0020] A sliding plate, slidably arranged on the partition plate, and the sliding plate is communicated with the sleeve rod through a liquid inlet pipe;

[0021] An extension pipe, communicating the sleeve rod with the drain pipe, and the drain pipe extends to a hole of the rotating disk.

[0022] One side of the connection box is communicated with a waste liquid pipe, and the inlet end of the waste liquid pipe is located above the partition plate to discharge the cleaning waste liquid.

[0023] The sealing assembly further includes:

[0024] A guiding rod, fixed in the connection box, and the sealing plate is slidably sleeved outside the guiding rod;

[0025] A spring, sleeved outside the guiding rod and having two ends respectively abutting against the sealing plate and the inner wall of the connection box to provide a restoring force for the sealing plate. Waist-shaped holes are formed on two sides of the connection box, and the connecting rod passes through the waist-shaped holes to allow the mounting seat to move axially. The outer wall of the rotating disk is sleeved with a rotating ring through a bearing. The outlet end of the drain pipe extends into the rotating ring. The holes are uniformly distributed along the circumferential direction of the rotating disk. One side of the connection box is provided with an elastic band and a positioning strip clamped with the outer sleeve to fix the position of the connection box.

[0026] An inspection method, applying the above visual inspection device for a tracheal cannula, includes the following steps:

[0027] S1. First, take out the inner core inside the inner sleeve, pull one end of the wire so that the core head moves into the rotating disk, and then install the connection box on one side of the outer sleeve;

[0028] S2. Second, push the wire to drive the core head to move, so that the core head enters the trachea through the inner sleeve, and check through the camera inside the core head;

[0029] S3. When the camera is contaminated with sputum, pull the wire to drive the core head to move into the rotating disk, and start the motor to drive the rotating disk to rotate and pump the cleaning liquid in the cavity into the rotating disk at the same time to wash the core head.

[0030] In the present invention, in the visual inspection device for a tracheal cannula, by arranging a micro camera inside the core head and using a wire to transmit the image information collected by the camera to an external display device, medical staff can directly and clearly observe the internal condition of the patient's trachea. Whether it is the color and shape of the tracheal mucosa, or the presence of foreign bodies, secretion accumulation and other abnormal conditions, can be accurately captured, providing a reliable basis for accurate diagnosis;

[0031] In the present invention, in the visual inspection device for a tracheal cannula, the cleaning mechanism is composed of a driving member, a positioning member and a water spraying member. Using the power of the driving member to drive the positioning member to rotate and the water spraying member to spray water, automatic cleaning of the core head is realized, without manual operation by medical staff, saving time and labor costs and improving work efficiency;

[0032] In the present invention, in the visual inspection device for a tracheal cannula, the cleaning mechanism further includes a sealing assembly. During the cleaning process, the sealing assembly can seal the through hole to prevent water droplets from entering the inner sleeve, effectively preventing water from irritating and infecting the trachea, ensuring the safety of the patient, reducing the risk of occurrence of complications. The sealing plate in the sealing assembly is connected to the mounting seat through a connecting rod. When the mounting seat moves, the connecting rod drives the sealing plate to slide on the guide rod. Under the action of the spring, the sealing plate can closely fit at the through hole to achieve a reliable sealing effect. At the same time, the waist-shaped hole provides space for the movement of the connecting rod, ensuring the rationality and stability of the whole structure;

[0033] In the present invention, tracheal visualization detection is realized through the micro camera inside the core head, and the elastic band and the positioning strip ensure stable wearing and connection; the cleaning mechanism drives the positioning member to rotate and the water spraying member to spray water with the help of the driving member, and cooperates with the sealing assembly to avoid water entering the inner sleeve when cleaning the core head, making the cleaning efficient and the sealing reliable.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Embodiment 1

[0044] Refer to Figures 1-7 , an inspector, which is used in cooperation with the outer sleeve 5 of the patient's larynx and is used for detecting the trachea, including: a connection box 2, an elastic band 3, a positioning strip 6, a mounting seat 14, a conducting wire 8, a core head 9, a cleaning mechanism, a sealing assembly and other parts.

[0045] The connection box 2 is detachably arranged on one side of the outer sleeve 5. The specific implementation method is as follows: A positioning strip 6 adapted to the outer sleeve 5 is provided on one side of the connection box 2, and the positioning of the connection box 2 is realized through the cooperation of the positioning strip 6 and the outer sleeve 5. A through hole 7 coaxial with the outer sleeve 5 is opened on one side of the connection box 2, facilitating the core head 9 to enter the outer sleeve 5 through the through hole 7 for detection.

[0046] The elastic band 3 is arranged on one side of the connection box 2 and is used to wear the connection box 2 around the patient's neck. Its wearing method is the same as the common wearing method of the elastic band. Through the elasticity of the elastic band, the connection box 2 can be stably fixed on the patient's neck.

[0047] An installation seat 14 is arranged in the connection box 2. A wire 8 penetrates through one side of the installation seat 14. One end of the wire 8 is connected with a core head 9. A micro camera is arranged in the core head 9. The battery cell in the wire 8 is connected with the micro camera, and the other end is connected with an external display device through the wire 8. Specifically, when implemented, the wire 8 passes through the installation seat 14, the core head 9 is fixed at one end of the wire 8, and the other end of the wire 8 is connected with an external display device (such as a display screen, etc.) through corresponding interfaces, realizing the transmission of the image signal collected by the micro camera to the display device. The wire 8 adopts a high-sensitivity wire to ensure stable transmission of the image signal, and the micro camera selects a high-resolution micro camera to ensure clear captured images.

[0048] The installation seat 14 is arranged in the connection box 2 through a connecting rod 13. A rotating disc 19 is rotatably arranged on one side of the installation seat 14 through a bearing. A guiding groove 24 is opened on the outer wall of the wire 8, and a sliding block located in the guiding groove 24 is welded in the installation seat 14. The wire 8 is limited by the sliding block and the guiding groove 24 to prevent the wire 8 from deviating during movement. A brush for cleaning the core head 9 is arranged in the rotating disc 19, and the brush can be fixed in the rotating disc 19 by means of glue or the like.

[0049] The cleaning mechanism is composed of a driving part, a positioning part, and a water spraying part. The positioning part and the water spraying part utilize the power of the driving part to drive the positioning part to rotate and the water spraying part to spray water, realizing the cleaning of the core head 9.

[0050] The positioning part includes parts such as a connecting rod 13, an installation seat 14, a rotating disc 19, and a brush. As described above, the installation seat 14 is welded on the connecting rod 13, the rotating disc 19 is rotatably arranged on one side of the installation seat 14 through a bearing, and the brush is arranged in the rotating disc 19. Its function is to drive the brush to clean the core head 9 during the cleaning process, removing dirt and secretions on the core head 9.

[0051] The drive assembly includes a motor 23 bolted to one side of the mounting base 14. A gear 22 is bolted to the output end of the motor 23. An outer ring gear 21, meshing with the gear 22, is welded to the outer wall of the rotating disk 19. When the motor 23 is operating, its output drives the gear 22 to rotate, and the gear 22 meshes with the outer ring gear 21, thereby driving the rotating disk 19 to rotate. This allows for accurate control of the rotational speed and direction of the rotating disk 19.

[0052] The water spraying component includes a partition 10 welded to the connecting box 2. A water storage cavity is formed between the partition 10 and the connecting box 2 for storing cleaning water. A sliding plate 11 is slidably mounted on the top of the partition 10 via a guide rail slider. Two liquid inlet pipes 31 are welded to the top of the sliding plate 11. The liquid inlet pipes 31 are supported by a support rod 30 between the connecting rod 13. The tops of the two liquid inlet pipes 31 are connected to the same sleeve rod 18. A piston rod 29 is slidably mounted within the sleeve rod 18. The piston block on the piston rod 29 divides the sleeve rod 18 into two cavities. The outer wall of the sleeve rod 18 is connected to two extension pipes 33. The outer ends of the two extension pipes 33 are fixed with a same drainage pipe 32. One end of the drainage pipe 32 extends into the rotating disk 19. One end of the piston rod 29 is in transmission connection with the rotating disk 19. The two sets of liquid inlet pipes 31 and extension pipes 33 correspond to the two cavities respectively. Each extension pipe 33 is equipped with a one-way valve to prevent the cleaning liquid from flowing.

[0053] To utilize the power of rotating disk 19 to drive the reciprocating movement of piston rod 29, an eccentric ring 20 is welded and fixed to the outer wall of rotating disk 19. An annular groove 26 is defined on one side of eccentric ring 20, and one end of piston rod 29 slides within annular groove 26 via a slider. When rotating disk 19 rotates, eccentric ring 20 rotates with it. Due to the eccentric design of eccentric ring 20, piston rod 29 reciprocates within sleeve rod 18. When piston rod 29 moves into sleeve rod 18, water in the water storage cavity is drawn into sleeve rod 18 through liquid inlet pipe 31. When piston rod 29 moves out of sleeve rod 18, the water in sleeve rod 18 is discharged into rotating disk 19 through extension pipe 33 and liquid discharge pipe 32.

[0054] The outer wall of the rotating disk 19 is provided with a rotating ring 25 through a bearing. One end of a drain pipe 32 extends into the rotating ring 25. The outer wall of the rotating disk 19 is provided with a plurality of holes 27 located within the rotating ring 25. Water is discharged from the drain pipe 32 and enters the rotating ring 25. Then, it is evenly sprayed onto the core head 9 through the holes 27, thereby flushing the core head 9. At the same time, a waste liquid pipe 4 is also connected to one side of the connecting box 2. At the same time, one end of the waste liquid pipe 4 is located above the partition 10, and the other end of the waste liquid pipe 4 extends to a trash can. The waste liquid pipe 4 is used to discharge the waste water used for cleaning into the trash can.

[0055] This application can be used in the field of medical devices, and can also be used in other fields applicable to this application.

[0056] Example 2

[0057] Reference Figures 1-7 , on the basis of Example 1, it is improved: a visual inspector for a tracheal cannula, which is applied to the field of medical devices. The sealing component is used to seal the through hole 7 during the cleaning process to prevent water from entering the inner cannula. The specific structure is that two guide rods 17 are welded to the inner wall of one side of the connection box 2. A sealing plate 16 corresponding to the through hole 7 is slidably arranged on one side of the two guide rods 17. A same connecting rod 15 is rotatably arranged between the sealing plate 16 and the mounting seat 14. A spring 28 is sleeved on the outer wall of the guide rod 17. The two ends of the spring 28 are respectively fixedly connected to the inner wall of one side of the sealing plate 16 and the outer wall of one end of the guide rod 17.

[0058] When the mounting seat 14 moves in the connection box 2, it drives the connecting rod 15 to move, and the connecting rod 15 pushes the sealing plate 16 to slide on the guide rod 17. When the cleaning starts, the mounting seat 14 moves, so that the sealing plate 16 approaches the through hole 7. Overcoming the acting force of the spring 28, the sealing plate 16 closely fits at the through hole 7 to realize the sealing of the through hole 7; when the cleaning is over, the sealing plate 16 moves back under the acting force of the spring 28, and uses the connecting rod 15 to drive the mounting seat 14 to move in the reverse direction to open the through hole 7, facilitating the entry and exit of the core head 9.

[0059] Waist-shaped holes 12 are opened on both sides of the connection box 2. The connecting rod 13 is located in the two waist-shaped holes 12. The waist-shaped holes 12 provide space for the movement of the connecting rod 13 to prevent the connecting rod 13 from detaching from the connection box 2, enabling the mounting seat 14 to move within a certain range in the connection box 2.

[0060] First, take out the inner core in the inner cannula, and pull one end of the wire 8 to make the core head 9 move into the rotating disc 19. Then install the connection box 2 on one side of the outer cannula 5, use the two positioning strips 6 and the outer cannula 5 for positioning, and then use the elastic band 3 to tie it around the neck to fix the connection box 2;

[0061] Secondly, push the wire 8 to drive the core head 9 to move, so that the core head 9 enters the trachea through the inner cannula, and the inspection is carried out through the camera inside the core head 9, and the situation inside the trachea is displayed in real time through an external display;

[0062] When the camera is contaminated with sputum, pull the wire 8 to drive the core head 9 to move into the rotating disk 19. Continue to pull, so that the core head 9 can contact the rotating disk 19 and drive the mounting seat 14 to move outward. During the process of the mounting seat 14 moving outward, it can drive the sealing plate 16 to move through the connecting rod 15, so that the sealing plate 16 seals the through hole 7, preventing water stains from entering the trachea, and start the motor 23. During the startup process of the drain pipe 32, it can drive the rotating disk 19 to rotate by using the gear 22 and the external tooth ring 21. The rotation of the rotating disk 19 can clean the core head 9 through the internal brush, and during the rotation of the rotating disk 19, it can drive the eccentric ring 20 to rotate. During the rotation of the eccentric ring 20, it can drive the piston rod 29 to move by using the annular groove 26. When the piston rod 29 moves to the right, the liquid in the right cavity of the sleeve rod 18 can be squeezed out. The liquid can enter the drain pipe 32 through the right extension pipe 33 and be sprayed onto the core head 9 through the rotating ring 25 and the hole 27. At the same time, the liquid in the cavity can be pumped into the left cavity of the sleeve rod 18 by using the left inlet pipe 31, and the liquid is pumped and sent in turn to wash the core head 9. And due to the combined use of the guide groove 24 and the mounting seat 14, the wire 8 can be limited, preventing the rotating disk 19 from driving the core head 9 to rotate when it rotates.

[0063] However, as is well known to those skilled in the art, the working principle and wiring method of the motor 33 are common knowledge, and they all belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any optional selection according to their needs or convenience.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
