Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visual tracheal intubation tube. Background Art

[0002] A tracheal tube is a medical device that is inserted into a patient's trachea or bronchus to create a temporary artificial breathing passage for the patient, especially for those who cannot breathe independently. The common intubation head has one or two cuffs. After the cuff is inflated, it can play a role in fixing the intubation and sealing the airway. It can also be without a cuff. The tube body of the intubation is usually made of polymer materials, and a steel wire coil is buried in the tube body to improve the radial strength and axial softness. Some tube bodies of the intubation adopt anti-laser materials or multi-layers to resist laser irradiation. It is an intubation for inserting into the patient's trachea through the nasal cavity or mouth. One end is connected to an anesthesia ventilator through a breathing pipeline to maintain the patient's breathing. It is provided aseptically and is for single use.

[0003] Tracheal tubes can be roughly divided into two categories: nasal type and oral type. Due to the situation that some patients have limited mouth opening and unstable cervical vertebrae, etc., nasal tracheal intubation is required. However, the nasal cavity structure of the patient is fragile, and the operation vision is smaller compared to the oral cavity. During the intubation process, the patient's nasal cavity may be scratched. It is necessary to use a camera to provide a visual environment for medical staff. At the same time, the intubation process will stimulate the patient's nasal cavity. The camera inserted into the human body together with the intubation is easily blocked by the patient's secretions, resulting in blurred camera lenses and affecting the operation of medical staff. At present, the camera is repeatedly inserted and pulled out for flushing, which not only increases the operation time of medical staff, but also may cause secondary harm to the patient during the insertion and extraction process, thus triggering complications such as nosebleeds, sinusitis and otitis media.

[0004] Therefore, the utility model provides a visual tracheal intubation tube to meet the needs. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a visual tracheal intubation tube to solve the problem that the current micro camera needs to be repeatedly inserted and pulled out for flushing, which not only affects the surgical vision but also may cause secondary harm to the patient.

[0006] To solve the above technical problem, the utility model provides the following technical solutions:

[0007] A visual tracheal intubation device includes a catheter. An airbag is fixedly connected to the outer wall of the catheter. An inflation connecting tube is fixedly connected to the outer wall of the airbag. An indicating balloon is fixedly connected to the top end of the inflation connecting tube. A flushing connecting tube is fixedly connected to the outer wall of the catheter. A flushing port is fixedly connected to the top end of the flushing connecting tube. A connector is inserted into one end of the catheter away from the airbag. A guide wire is inserted into the inner wall of the connector. Four groups of limiting grooves are formed on the inner wall of the catheter; a drainage assembly for collecting the patient's secretions and connected to the catheter; a fixing assembly for pre-positioning the position of a camera and connected to the drainage assembly.

[0008] Optionally, the drainage assembly includes an adapter plate inserted into the limiting groove. The number of the adapter plates is four. One end of each of the four adapter plates is fixedly connected to the same adapter sleeve. A convex block is fixedly connected to the outer wall of the adapter sleeve.

[0009] Optionally, a lower support bladder is fixedly connected to one end of the adapter sleeve away from the adapter plate. An upper support bladder is fixedly connected to the upper end of the lower support bladder. A pointed end is fixedly connected to one end of the upper support bladder. A storage groove is formed at one end of the lower support bladder close to the upper support bladder.

[0010] Optionally, drainage inclined plates are symmetrically installed on the inner wall of the upper support bladder. Arc-shaped drainage plates are fixedly connected to both sides of the two drainage inclined plates.

[0011] Optionally, drainage ports are symmetrically formed at one end of the upper support bladder close to the drainage inclined plates. The upper support bladder is connected to the fixing assembly.

[0012] Optionally, the fixing assembly includes fixing brackets symmetrically installed on the upper support bladder. The number of the fixing brackets is two.

[0013] Optionally, arc-shaped clamping plates are fixedly connected to one end of the two fixing brackets away from the upper support bladder. A micro camera is inserted into the inner walls of the two arc-shaped clamping plates.

[0014] Optionally, an elastic cord is fixedly connected to one end of the fixing bracket close to the arc-shaped clamping plate. A limiting plate is fixedly connected to one side of the fixing bracket.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up the drainage component, not only can the discomfort caused by inserting the tube into the patient's nasal cavity be reduced, but also the secretions in the patient's body can be guided and collected, thereby preventing the secretions from blocking the lens of the micro camera and limiting the vision of medical staff, and facilitating the medical staff to quickly insert the tube into the patient's body.

[0017] The lower support bladder and the upper support bladder are integrally structured and made of silica gel material, with good flexibility and elasticity. The connection between the lower support bladder and the upper support bladder is a rounded corner that is concave inward, and together with the thin sheet that turns outward above the lower support bladder, it forms a storage groove. This structure enables the upper support bladder to be deformed by squeezing into the concave area during the process of entering the patient's body, reducing the patient's discomfort. At the same time, the secretions in the patient's body can enter the storage groove along the contour of the upper support bladder. Moreover, the top of the lower support bladder is provided with fine holes, and the secretions can enter the chamber formed by the lower support bladder and the upper support bladder through the holes for collection, avoiding the secretions from blocking the surgical vision of medical staff.

[0018] The position of the micro camera can be fixed by the set fixing component, making the micro camera always located at the central position of the above-mentioned catheter. This not only makes the surgical vision wider, but also can reduce the phenomenon of secretions blocking the lens of the micro camera under the action of the above-mentioned drainage component.

[0019] The arc-shaped clamping plate is connected to the fixed bracket through an elastic rope, and the elastic rope has elasticity. When the arc-shaped clamping plate clamps the micro camera, it can be displaced under the action of the elastic rope. At the same time, the limiting plate, which is integrally structured with the fixed bracket, can limit the displaced position of the arc-shaped clamping plate, further avoiding excessive displacement of the arc-shaped clamping plate and being unable to fix the micro camera. This enables the micro camera to be far away from the upper support bladder, reducing contact with the secretions while also being able to make fine adjustments to the angle, increasing the practicality of the intubation tube.

[0020] By setting up the drainage component and the fixing component, the two cooperate with each other to reduce the phenomenon of secretions adhering to the surface of the micro camera during the insertion of the catheter. The whole is made of silica gel material, with good flexibility and elasticity, low cost, more practicality, and can reduce the contact between the micro camera and the secretions, further improving the surgical vision and avoiding secondary harm to the patient caused by repeated insertion and extraction.

[0038] Such as Figures 1 to 8As shown in the figure, an embodiment of the present utility model provides a visual tracheal intubation tube, which includes a catheter 1. An airbag 2 is fixedly connected to the outer wall of the catheter 1. An inflation connection tube 5 is fixedly connected to the outer wall of the airbag 2. An indicating balloon 6 is fixedly connected to the top end of the inflation connection tube 5. A flushing connection tube 3 is fixedly connected to the outer wall of the catheter 1. A flushing port 4 is fixedly connected to the top end of the flushing connection tube 3. One end of the catheter 1 away from the airbag 2 is inserted with a connector 7. A guide wire 8 is inserted into the inner wall of the connector 7. Four groups of limiting grooves 9 are formed on the inner wall of the catheter 1; a drainage assembly, which is used to collect the secretions of the patient and is connected to the catheter 1; a fixing assembly, which is used to pre-position the position of the camera and is connected to the drainage assembly. Specifically, after the catheter 1 is fully softened in saline, it is inserted into the trachea through the glottis from the patient's nasal cavity by medical staff. The drainage assembly is used to drain and collect the secretions in the nasal cavity and trachea, and is cleaned through the flushing connection tube 3 and the flushing port 4. It should be noted that the flushing connection tube 3 and the flushing port 4 are two separate groups, one for flushing and one for aspiration, to avoid the secretions blocking the medical staff's vision during the insertion process.

[0039] As Figures 2 to 4 shown, the drainage assembly includes an adapter plate 10 inserted into the limiting groove 9. The number of the adapter plates 10 is four groups. One ends of the four groups of adapter plates 10 are fixedly connected to the same adapter sleeve 11. A raised block 19 is fixedly connected to the outer wall of the adapter sleeve 11. Specifically, the adapter plate 10 and the adapter sleeve 11 are of an integral structure, and the middle position of the inner wall of the adapter sleeve 11 is made of rubber material. The connection position between the adapter plate 10 and the adapter sleeve 11 is at an inclined angle, and the other end is a rounded corner that turns outwards. This structure enables the whole adapter plate 10 to be inclined at an angle. After being inserted into the limiting groove 9, the rounded corner of the adapter plate 10 can abut against the limiting groove 9, thereby realizing the connection between the catheter 1 and the adapter sleeve 11. When replacement is needed, the four groups of adapter plates 10 can be held, so that the rounded corners thereof are separated from the edge of the limiting groove 9, and the adapter sleeve 11 can be pulled out along the end of the catheter 1.

[0040] As Figure 2 and Figures 6 to 7As shown in the figure, one end of the connecting circular sleeve 11 away from the connecting plate 10 is fixedly connected with a lower support bladder 12. The upper end of the lower support bladder 12 is fixedly connected with an upper support bladder 13. One end of the upper support bladder 13 is fixedly connected with a pointed end portion 101. A storage groove 22 is formed at one end of the lower support bladder 12 close to the upper support bladder 13. Drainage inclined plates 14 are symmetrically installed on the inner wall of the upper support bladder 13. Arc-shaped drainage plates 15 are fixedly connected to both sides of the two drainage inclined plates 14. Drainage openings 16 are symmetrically formed at one end of the upper support bladder 13 close to the drainage inclined plates 14. The upper support bladder 13 is connected with a fixing component. The position of the trachea can be guided through the pointed end portion 101, and its surface is relatively smooth to reduce the damage to the oral cavity, pharynx, glottis and tracheal mucosa during the insertion process. And Murphy holes are provided on the side to increase the ventilation efficiency. Specifically, the connecting circular sleeve 11, the lower support bladder 12 and the upper support bladder 13 are of an integral structure, made of silica gel material, with good flexibility and elasticity. The connection between the lower support bladder 12 and the upper support bladder 13 is a rounded corner that is recessed inward and forms a storage groove 22 with the thin sheet that turns outward above the lower support bladder 12. This structure enables the upper support bladder 13 to be deformed by squeezing into the recessed part during the process of entering the patient's body, reducing the discomfort of the patient. At the same time, the secretions in the patient's body can enter the storage groove 22 along the contour of the upper support bladder 13. And fine holes are formed at the top of the lower support bladder 12, and the secretions can enter the chamber formed by the lower support bladder 12 and the upper support bladder 13 through the holes for collection, avoiding the secretions from blocking the surgical field of vision of the medical staff.

[0041] Furthermore, the arc-shaped drainage plates 15, the drainage inclined plates 14 and the upper support bladder 13 are of an integral structure and made of the same material. The arc-shaped drainage plates 15 are fixed at the edge of the top of the upper support bladder 13 and are in a corrugated shape. The two arc-shaped drainage plates 15 are connected through the drainage inclined plates 14, and the bending arc of the arc-shaped drainage plate 15 at the connection is larger. And the shape of the drainage inclined plate 14 is a side plate that inclines into the drainage opening 16. This structure enables the secretions generated by the patient during the insertion process to enter the chamber formed by the lower support bladder 12 and the upper support bladder 13 through the drainage opening 16 along the bending arc of the arc-shaped drainage plate 15, further reducing the phenomenon of the secretions blocking the surgical field of vision of the medical staff.

[0042] As Figures 3 to 7As shown in the figure, the fixing component includes fixing brackets 17 symmetrically installed on the upper support bladder 13. The number of fixing brackets 17 is two groups. At one end of the two groups of fixing brackets 17 away from the upper support bladder 13, arc-shaped clamping plates 18 are fixedly connected. A same micro camera 23 is inserted on the inner walls of the two arc-shaped clamping plates 18. One end of the fixing bracket 17 close to the arc-shaped clamping plate 18 is fixedly connected with an elastic cord 20. One side of the fixing bracket 17 is fixedly connected with a limiting plate 21. By providing the arc-shaped clamping plates 18, the position of the micro camera 23 can be fixed, so that the micro camera 23 is always located at the central position of the above-mentioned catheter 1. This not only makes the surgical field of view wider, but also can reduce the phenomenon that the secretions block the lens of the micro camera 23 under the action of the above-mentioned drainage component. Specifically, the arc-shaped clamping plate 18 is a corrugated clamping plate, with the middle part protruding outward and the two ends protruding inward. And the two arc-shaped clamping plates 18 are symmetrically installed at the middle part of the top of the upper support bladder 13 through the fixing brackets 17 to realize the pre-positioning of the micro camera 23. Further, the arc-shaped clamping plate 18 is connected to the fixing bracket 17 through the elastic cord 20, and the elastic cord 20 has elasticity. When the arc-shaped clamping plate 18 clamps the micro camera 23, it can shift in position under the action of the elastic cord 20. At the same time, the limiting plate 21, which is an integral structure with the fixing bracket 17, can limit the shifted position of the arc-shaped clamping plate 18, further avoiding excessive position shift of the arc-shaped clamping plate 18 and unable to fix the micro camera 23. This enables the micro camera 23 to be away from the upper support bladder 13, reducing contact with the secretions while also being able to perform fine angle adjustment, increasing the practicality of the intubation.

[0043] The working principle of the present utility model is as follows: Since the connecting circular sleeve 11, the lower support bladder 12 and the upper support bladder 13 are of an integral structure and made of silica gel material, they have good flexibility and elasticity. The size of the overall contour of the upper support bladder 13 is the same as that of the catheter 1, and the upper support bladder 13 is made of soft silica gel. Therefore, during the process of inserting the upper support bladder 13 into the patient's nasal cavity, it will not affect the patient's comfort, nor will it affect the overall insertion effect of the catheter 1 due to the protrusion of the structure at a certain part of the pipeline. Before use, first soften it and the catheter 1 in saline. At this time, the medical staff can insert the connecting plate 10 into the limiting groove 9 on the inner wall of the catheter 1. Since the connection between the connecting plate 10 and the connecting circular sleeve 11 is at an inclined angle, and the middle position of the inner wall of the connecting circular sleeve 11 is made of rubber material, it can cooperate with the rounded corner at the bottom of the connecting plate 10 to realize the connection between the connecting circular sleeve 11 and the catheter 1. The medical staff inserts the catheter 1 into the trachea through the glottis from the patient's nasal cavity and adjusts the angle of the catheter 1 through the guide wire 8. During the insertion and extrusion process, the contact surface of the upper support bladder 13 is larger and it can deform inwardly, so that the secretions in contact with it flow into the storage groove 22 along the upper support bladder 13. At the same time, the arc-shaped drainage plate 15 at the top of the upper support bladder 13 can also send the secretions into the drainage port 16 and collect them together with the secretions in the storage groove 22 in the chamber formed by the lower support bladder 12 and the upper support bladder 13. And the convex design of the convex block 19 can reduce the phenomenon of secretion reflux. If the micro camera 23 is blocked by secretions during this process, it can be flushed through the flushing connecting pipe 3 and the flushing port 4 and the secretions can be aspirated, avoiding the extension of the operation time caused by repeated insertion and extraction of the micro camera 23 and reducing the risk of secondary injury to the patient caused by the insertion and extraction of the micro camera 23. At the same time, the fixing bracket 17 and the arc-shaped clamping plate 18 on the inner wall of the upper support bladder 13 can limit the micro camera 23 when the micro camera 23 extends in. And the corrugated shape of the arc-shaped clamping plate 18 cooperates with the elastic cord 20 to enable the micro camera 23 to adjust the angle when it is located at the central part of the catheter 1, increasing the surgical field of view, and being located at the middle part can minimize its contact with the secretions and reduce the time for cleaning the mirror surface of the micro camera 23. After the position of the catheter 1 is fixed, the airbag 2 is inflated through the inflation connecting pipe 5 and the indicating balloon 6 to make it fit the patient's trachea, completing the work of delivering oxygen to the trachea and protecting the airway, etc.
