Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a visual suction aid for endotracheal intubation care. Background Technology

[0002] In clinical care, endotracheal intubation is typically used in semi-emergency situations to provide ventilation for patients with respiratory failure who may be conscious or semi-conscious. Patients with endotracheal intubation often require suctioning due to airway secretion retention to maintain airway patency and prevent complications such as pulmonary infection.

[0003] Traditional suctioning procedures rely heavily on the experience of healthcare professionals who perform self-intubation, which presents several problems. Firstly, the inability to directly observe the airway makes it difficult to accurately determine the location and amount of sputum, leading to imprecise suctioning and potential omission of sputum, thus affecting its effectiveness. Secondly, the suction catheter occupies space within the endotracheal tube, reducing oxygen delivery and causing breathing difficulties that can lead to patient panic. This process can also cause suffocation or gagging, resulting in regurgitation and the removal of stomach contents.

[0004] Therefore, an improved device is needed to ensure that the patient's airway is open and also allows the patient to continue receiving oxygen during suctioning catheter insertion and suctioning. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a visual suction aid cover for endotracheal intubation care, which effectively solves the problems that traditional endotracheal intubation patients cannot directly observe the internal condition during suctioning and that occupying space inside the endotracheal tube leads to reduced oxygen delivery.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a curved tubular guide tube, the guide tube having a distal opening and a proximal opening, an auxiliary cover surrounding the distal opening of the guide tube, the auxiliary cover being made of a soft, elastic material, and the auxiliary cover sealing the throat inlet around the distal opening of the guide tube; a ventilation element is detachably connected to the proximal opening of the guide tube, the ventilation element including a ventilation channel communicating with the guide tube and an insertion channel for inserting an endotracheal tube, a detachable connector being connected to the insertion channel, and an endotracheal tube being inserted through the connector and the insertion channel; a camera and a light source are provided at the front end of the endotracheal tube.

[0007] Preferably, the ventilation device further includes a sealing ring within the insertion channel, which can surround the endotracheal tube for sealing when the endotracheal tube is inserted and passes through the ventilation device.

[0008] Preferably, a duckbill valve is fixedly connected inside the connector.

[0009] Preferably, the connector includes a first insertion part that mates with a sealing ring and a second insertion part that mates with an insertion channel. A limiting part is provided above the first insertion part and the second insertion part, and an extension part is provided above the limiting part. The duckbill valve is located within the extension part.

[0010] Preferably, the side of the guide tube is provided with a vent hole communicating with it, and the venting component includes a connecting tube and a venting tube that are connected together. The connecting tube is connected to the outside of the guide tube and covers the vent hole so that the venting tube and the vent hole are connected to form a venting channel.

[0011] Preferably, the upper side of the distal end of the guide tube is provided with a protrusion integrally connected to the guide tube and extending forward and upward; the lower side of the distal end of the guide tube is provided with a support member integrally connected to the guide tube and in an arc shape.

[0012] Preferably, the auxiliary cover surrounds the distal opening of the guide tube and the support member, the auxiliary cover is connected to an inflation tube, the end of the inflation tube away from the auxiliary cover is connected to an indicator balloon, and the indicator balloon is also connected to an inflation connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Enables visualized airway operation and improves the accuracy of sputum suction; The endotracheal tube integrates a camera and light source at the front end, which can transmit images inside the airway to external devices in real time, allowing medical staff to intuitively observe the location of sputum and accurately control the movement of the suction tube. This completely solves the problem of sputum residue caused by traditional "blind probing" operation, reduces repeated operations caused by positioning deviation, and lowers the risk of airway mucosal damage.

[0015] 2. Maintain continuous ventilation during suctioning to avoid oxygen interruption; the dual-channel design of the ventilation device (ventilation channel and insertion channel) allows external oxygen to be continuously delivered to the lungs through an independent ventilation channel when the suction catheter enters the airway via the insertion channel. This avoids ventilation interruption caused by traditional suction catheters occupying the airway, reducing the risk of decreased blood oxygenation, suffocation, and panic reactions in patients. The sealing ring and duckbill valve form a double dynamic seal, effectively preventing gas leakage from the insertion channel and ensuring continuous ventilation.

[0016] 3. Optimize sealing performance and adapt to human anatomy; the auxiliary cover is made of soft and elastic material, which can be inflated to fit tightly to the throat inlet. With the help of the indicator balloon, the internal pressure is reflected in real time, avoiding tissue damage caused by over-inflation or air leakage caused by under-inflation, thus balancing sealing and safety.

[0017] The guide tube's bending angle is adapted to the structure of the human pharynx, and the protrusion at the distal end can lift the pharynx to maintain airway patency. The arc-shaped support component fits against the tracheal wall to stabilize the device's position, while simultaneously blocking the esophagus to prevent gastric reflux and improving operational stability.

[0018] 4. Enhanced operational safety and reduced risk of complications: The flexible auxiliary mask and support components disperse pressure to avoid compression damage to laryngeal tissues, solving the tissue damage problem of traditional rigid sealing structures. The combination of continuous ventilation and visualization reduces complications such as regurgitation and aspiration caused by blind operation and hypoxia, and improves the operational tolerance of conscious or semi-conscious patients.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In existing technologies, patients with endotracheal intubation face the dual challenges of insufficient airway visibility and ventilation interruption during suctioning. Traditional methods rely on the experience of medical staff to blindly probe the suction catheter, which cannot accurately locate the sputum. During the procedure, the suction catheter occupies airway space, causing oxygen supply interruption and potentially leading to decreased blood oxygenation or reflux risk. For example, when the patient is in a semi-conscious state, the feeling of suffocation caused by suctioning may exacerbate their panic response.

[0031] To address the aforementioned issues, the research focus shifted to maintaining continuous ventilation and enabling visualization during suctioning. Early attempts attempted to achieve ventilation and suctioning through separate channels, but the multi-channel design resulted in increased device size, making it difficult to accommodate the standard endotracheal tube 10. Further exploration revealed that integrating the visualization component into the front end of the suction tube 14 solved the positioning problem, but it could not prevent airway closure during insertion of the suction tube 14. Therefore, an auxiliary structure was proposed to be placed outside the tube, which can both seal the airway to prevent air leakage and accommodate the introduction of visualization equipment.

[0032] Reference Figure 1-8 As shown, this application proposes a visual suction aid for endotracheal intubation, including a curved tubular guide tube 1. The guide tube 1 has a distal opening 101 and a proximal opening 102. An aid hood 2 made of soft elastic material is provided around the distal opening 101 of the guide tube 1, and the aid hood 2 seals the laryngeal inlet around the distal opening 101 of the guide tube 1. A ventilation component 3 is detachably connected to the proximal opening 102 of the guide tube 1. The ventilation component 3 includes a ventilation channel 301 communicating with the guide tube 1 and an insertion channel 302 for inserting an endotracheal tube 10. A detachable connector 4 is connected to the insertion channel 302. The endotracheal tube 10 is inserted through the connector 4 and the insertion channel 302. A camera 11 and a light source 12 are provided at the front end of the endotracheal tube 10.

[0033] The tubular guide tube 1 is a hollow catheter with a curved shape, which can be injection molded from medical-grade silicone or polyurethane. Its curvature angle can be adapted to the anatomical structure of the human pharynx and larynx to establish the connection path between the suction catheter 14 and the airway. The auxiliary cover 2 is a flexible sealing component wrapped around the distal end of the guide tube 1, which can be a silicone balloon or an elastic membrane structure. It forms a sealed space by contacting the laryngeal tissue to prevent gas leakage during operation. The ventilation component 3 is a composite interface connected to the proximal end of the guide tube 1. It can be a split injection molded component with independent channels inside to realize gas transmission and instrument introduction respectively, ensuring that the suction catheter 14 maintains ventilation function when inserted.

[0034] Specifically, the auxiliary cover 2 elastically deforms to fit snugly against the laryngeal inlet, creating a sealed environment to prevent gas leakage. The ventilation channel 301 of the ventilation component 3 is internally connected to the guide tube 1. When the suction tube 14 enters the airway through the insertion channel 302, external oxygen can be continuously delivered to the patient's lungs through the ventilation channel 301. The camera 11 and light source 12 at the front end of the endotracheal tube 10 transmit images of the airway in real time to an external display device, allowing the operator to observe the position of sputum and precisely control the movement of the suction tube 14. When it is necessary to replace or clean parts, the detachable connector 4 allows for quick separation of the ventilation component 3 from the endotracheal tube 10.

[0035] Through the above technical solutions, this application simultaneously achieves airway visualization and continuous ventilation during sputum suctioning, eliminating the problem of sputum residue caused by blind probing and reducing the risk of decreased blood oxygenation in patients. The flexible sealing structure of the auxiliary cover 2 avoids laryngeal compression injury, and the detachable ventilation component 3 design improves the efficiency of device cleaning and maintenance, making it suitable for the repeated sputum suctioning needs of conscious patients.

[0036] This application further proposes a sealing ring 7 within the insertion channel 302, which can surround the endotracheal tube 10 for sealing when the endotracheal tube 10 is inserted and passes through the ventilation element 3.

[0037] The sealing ring 7 refers to an annular sealing structure installed inside the insertion channel 302. It can be made of elastic materials such as silicone or rubber, and achieves a seal by wrapping the outer wall of the endotracheal tube 10 through its elastic deformation. This structure is used to prevent gas leakage from the gap between the endotracheal tube 10 and the insertion channel 302 during the suctioning operation, and to maintain the airtightness of the ventilation channel 301.

[0038] Specifically, when the endotracheal tube 10 enters the guide tube 1 through the insertion channel 302, the sealing ring 7 is elastically deformed by the compression of the outer wall of the endotracheal tube 10, thus forming a tight annular seal against the surface of the endotracheal tube 10. This sealing effect prevents gas in the ventilation channel 301 from leaking out through the insertion channel 302 during suctioning, while allowing the endotracheal tube 10 to move freely within the channel. In this state, medical staff can observe the location of sputum and perform precise suctioning through the camera 11 at the front end of the endotracheal tube 10, while the patient can still continuously receive oxygen through the ventilation channel 301, avoiding ventilation interruption due to gas leakage.

[0039] Through the above technical solution, this application can maintain stable ventilation during sputum suction, avoid patients from experiencing hypoxia or respiratory distress due to gas leakage, reduce the risk of medical staff misjudging the location of sputum due to gas leakage interference, and improve the safety and effectiveness of sputum suction.

[0040] This application further proposes that a duckbill valve 5 is fixedly connected inside the connector 4.

[0041] Among them, the duckbill valve 5 refers to an elastic sealing structure with one-way opening and closing function. Specifically, it can be made of silicone or rubber material, and its cross-sectional shape is flat and closed. When subjected to external pressure, it can form a channel opening. This structure is configured to allow the endotracheal tube 10 to pass through when it is inserted, and to return to the closed state to block the gas flow when no external force is applied.

[0042] The connector 4 is a transition component used to connect the endotracheal tube 10 and the insertion channel 302. It can be made of medical-grade plastic material and has an annular groove for fixing the duckbill valve 5 inside. The duckbill valve 5 and the inner wall of the connector 4 are integrated through injection molding.

[0043] Specifically, the duckbill valve 5 is fixed within the extension 403 of the connector 4. When the endotracheal tube 10 passes through the insertion channel 302, the flat, closed end of the duckbill valve 5 is compressed by the outer wall of the tube and unfolds, forming a channel that allows the tube to pass through. When the tube is removed after suctioning, the duckbill valve 5 returns to its closed state due to the loss of external force, thereby preventing gas from escaping from the insertion channel 302. During this process, the ventilation channel 301 remains connected to the guide tube 1, ensuring that the patient receives a continuous oxygen supply.

[0044] Through the above technical solution, this application effectively solves the problem of ventilation interruption caused by gas leakage during sputum suction, ensures the airtightness of the patient's respiratory support system, reduces the risk of hypoxemia during the operation, and simplifies the operation steps for medical staff.

[0045] This application further proposes a first insertion part 401 that cooperates with the sealing ring 7 and a second insertion part 404 that cooperates with the insertion channel 302. A limiting part 402 is provided above the first insertion part 401 and the second insertion part 404, and an extension part 403 is provided above the limiting part 402. The duckbill valve 5 is located in the extension part 403.

[0046] The first insertion part 401 refers to the cylindrical structure in the connector 4 that is used to form contact with the sealing ring 7. Specifically, it can be implemented by using a silicone kit with an annular groove, which forms a preliminary seal through interference fit with the sealing ring 7.

[0047] The second insertion part 404 refers to the tubular structure in the connector 4 used to form a connection with the insertion channel 302. Specifically, it can be made of polyurethane material with an outer diameter slightly larger than the inner diameter of the insertion channel 302, and it fits tightly against the inner wall of the insertion channel 302 through elastic deformation.

[0048] The limiting part 402 refers to the annular boss located between the first insertion part 401 and the second insertion part 404. Specifically, it can be implemented by injection molding of a hard plastic part, which is used to limit the insertion depth of the connector 4 and prevent excessive displacement.

[0049] The extension 403 refers to the tubular extension structure located above the limiting part 402. Specifically, it can be implemented by using a transparent medical-grade plastic part integrally formed with the limiting part 402, which is used to accommodate the duckbill valve 5 and form a gas barrier space.

[0050] Specifically, when connector 4 is installed into insertion channel 302, the second insertion part 404 forms a fixed connection with the inner wall of insertion channel 302 through elastic deformation, while the limiting part 402 abuts against the port of insertion channel 302 to ensure that connector 4 is in the preset installation position. The first insertion part 401 forms an interference fit with sealing ring 7, and after endotracheal tube 10 passes through sealing ring 7, an annular sealing surface is formed between its outer wall and sealing ring 7. The duckbill valve 5 provided inside extension part 403 remains closed when no external force is applied. When endotracheal tube 10 passes through duckbill valve 5, its elastic lip is tightly against the outer wall of the tube, forming a second sealing barrier; in addition, connector 4 can also be used for operations such as medication administration.

[0051] Through the above technical solution, this application effectively prevents gas from escaping from the insertion channel 302 during sputum suction, avoiding interruption of patient ventilation. Simultaneously, the limiting part 402 ensures accurate positioning of the connector 4 and the insertion channel 302, reducing the risk of seal failure due to installation deviation. The elastic closing characteristic of the duckbill valve 5 further ensures the integrity of the seal when the intubation tube is temporarily withdrawn.

[0052] This application further proposes that the guide tube 1 has a vent hole 6 connected to it on the side, and the venting component 3 includes a connecting pipe 303 and a venting pipe 304 connected to each other. The connecting pipe 303 is connected to the outside of the guide tube 1 and covers the vent hole 6 so that the venting pipe 304 is connected to the vent hole 6 to form a venting channel 301.

[0053] Among them, the vent 6 refers to the hole-like structure set on the side wall of the guide tube 1, which can be implemented by circular or elliptical holes, and is used to establish a channel for gas exchange between the inside and outside of the guide tube 1.

[0054] Among them, the connecting pipe 303 refers to a tubular component with a hollow structure, which can be made of silicone or polyurethane material, and is used to cover and seal the vent 6 to achieve directional gas flow.

[0055] Among them, the ventilation tube 304 refers to the extension tube connected to the connecting tube 303. Specifically, it can be made of flexible and bendable medical-grade plastic tubing to form a gas delivery path independent of the main channel of the guide tube 1.

[0056] Among them, the ventilation channel 301 refers to the independent gas transmission space formed by the ventilation tube 304 and the ventilation port 6. Specifically, it can be achieved by matching the tube diameter and sealing the interface, and is used to maintain the continuity of the patient's respiratory function during sputum suction.

[0057] Specifically, after a ventilation hole 6 is opened on the side of the guide tube 1, the connecting tube 303 covers the ventilation hole 6 through a sleeve connection and forms a sealed connection with the ventilation tube 304. When the suction catheter 14 is inserted into the guide tube 1, external oxygen or air can continuously enter the patient's airway through the ventilation tube 304 and the ventilation hole 6, forming a gas supply path independent of the suction operation. This design allows gas to continue to be delivered through the side ventilation channel 301 when the suction catheter 14 moves within the guide tube 1, avoiding the gas interruption problem caused by the suction catheter 14 blocking the main channel in traditional operations.

[0058] Through the above technical solution, this application can maintain the patient's respiratory function during the insertion and movement of the suction catheter 14, avoiding the risk of suffocation caused by gas interruption, and reducing the patient's panic response due to hypoxia. The establishment of the independent ventilation channel 301 eliminates the need for medical staff to frequently adjust the position of the suction catheter 14 to restore oxygen supply during operation, significantly improving the safety and continuity of the suctioning procedure.

[0059] This application further proposes a visual suction aid hood 2 for endotracheal intubation 10, wherein a protrusion 103 is provided on the upper side of the distal end of the guide tube 1, which is integrally connected to the guide tube 1 and extends forward and upward; and a support member 104 is provided on the lower side of the distal end of the guide tube 1, which is integrally connected to the guide tube 1 and is arc-shaped.

[0060] The protrusion 103 refers to the raised portion that forms a continuous structure with the upper distal end of the guide tube 1. When inserted into the patient's epipharynx, the protrusion 103 pushes the epipharynx up from the laryngeal inlet, helping to ensure airway patency. The support member 104 refers to the arc-shaped structure located on the lower distal end of the guide tube 1. Specifically, it can be made of a flexible medical-grade polymer material integrally molded with the guide tube 1. The arc-shaped design can conform to the shape of the tracheal wall, providing stable support when the auxiliary cover 2 seals the laryngeal inlet, preventing displacement of the guide tube 1 during operation, and preventing esophageal obstruction and gastric reflux.

[0061] Specifically, during the suctioning procedure, the guide tube 1 is fixed to the entrance of the patient's larynx via the auxiliary cover 2. At this time, the distal protrusion 103 extends along the anterior wall of the pharynx, and its forward and upward extension conforms to the anatomical structure of the pharynx, thus guiding and maintaining airway patency. Simultaneously, the support member 104 fits against the lower side of the tracheal wall in an arc shape, dispersing pressure through the contact surface with the tracheal wall to avoid discomfort caused by local stress concentration, and maintaining the stability of the guide tube 1 during suctioning. This prevents device displacement caused by patient movement or changes in operating force, ensuring that the suction tube 14 and camera 11 remain in the correct position within the airway, while also obstructing the esophagus to prevent gastric reflux.

[0062] Through the above technical solution, this application can effectively maintain the positioning accuracy and stability of the guide tube 1 during sputum suction, reduce repeated adjustment operations caused by device movement, improve the smoothness and safety of the sputum suction process, reduce patient discomfort caused by device compression, and ensure that sputum suction and ventilation functions are carried out simultaneously.

[0063] This application further proposes that the auxiliary cover 2 surrounds the distal opening 101 of the guide tube 1 and the support member 104, the auxiliary cover 2 is connected to the inflation tube 13, the end of the inflation tube 13 away from the auxiliary cover 2 is connected to the indicator balloon 8, and the indicator balloon 8 is also connected to the inflation connector 94.

[0064] Among them, the auxiliary cover 2 refers to the flexible sealing structure that wraps around the distal opening 101 of the guide tube 1 and the support member 104. Specifically, it can be made of silicone or rubber material, and achieves a sealed fit with the throat inlet by inflation.

[0065] The inflation tube 13 refers to the flexible conduit connecting the auxiliary cover 2 and the indicator balloon 8. Specifically, it can be made of silicone or rubber tubing and is used to deliver gas to the auxiliary cover 2 and transmit pressure changes.

[0066] Among them, the indicator balloon 8 is a visualization device used to display the internal pressure of the auxiliary cover 2. Specifically, it can be implemented by a transparent elastic bladder, and the inflation status of the auxiliary cover 2 can be judged by observing its degree of expansion.

[0067] Among them, the inflation connector 94 refers to the interface used to connect to external inflation equipment. Specifically, it can be implemented using a one-way valve structure to prevent gas leakage and control the inflation volume.

[0068] Specifically, the auxiliary cover 2 forms a closed inflation system with the indicator balloon 8 via the inflation tube 13. When gas is injected into the auxiliary cover 2 through the inflation connector 94, the auxiliary cover 2 inflates and seals with the laryngeal inlet, at which time the indicator balloon 8 inflates synchronously. The operator can judge whether the auxiliary cover 2 has reached the preset pressure by observing the degree of inflation of the indicator balloon 8, avoiding over-inflation that could cause tissue compression damage. The cooperation between the support member 104 and the auxiliary cover 2 can stabilize the position of the guide tube 1 and prevent the device from shifting during suctioning.

[0069] Through the above technical solution, this application can maintain stable airway sealing during sputum suction, and at the same time, the indicator balloon 8 reflects the internal pressure of the auxiliary cover 2 in real time, avoiding leakage of secretions due to insufficient inflation or tissue damage caused by over-inflation, thereby improving the safety and reliability of operation.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
