Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a nasal cavity-inserted endotracheal intubation examination and drug delivery device. Background Technology

[0002] In clinical practice, endotracheal intubation is a crucial emergency and treatment procedure aimed at establishing an artificial airway to ensure the patient's breathing is unobstructed. Therefore, during endotracheal intubation, physicians must ensure accurate intubation placement and the absence of complications.

[0003] However, after endotracheal intubation, patients may experience edema in the larynx, especially in the pharynx. This not only increases patient suffering, but if the edema is not addressed promptly, it can lead to tube displacement, interfering with normal respiratory function and causing serious complications such as respiratory distress and suffocation, threatening the patient's life. Furthermore, gaps between the tube and the tracheal wall can cause gas leakage, reducing the efficiency of mechanical ventilation and affecting respiratory support. These gaps can also increase the risk of aspiration, allowing oral secretions and gastric contents to enter the trachea, leading to lung infections, aspiration pneumonia, and other conditions, further aggravating the patient's condition and prolonging the treatment period. Currently, medical devices on the market are multifunctional but limited in scope, lacking an integrated device that can simultaneously perform upper respiratory tract edema examination, drug administration, and endotracheal tube / tracheal gap detection. In clinical practice, medical staff often need to use multiple different devices for these procedures, which is not only cumbersome and increases the workload of medical personnel, but also may cause delays in equipment changes, missing the optimal examination and treatment time, hindering the patient's rapid recovery.

[0004] Therefore, developing a nasal-inserted endotracheal intubation examination and drug delivery device with multiple functions has become an urgent need in the current medical device field. Summary of the Invention

[0005] The purpose of this invention is to provide a nasal cavity-inserted endotracheal intubation examination and drug administration device, which solves the problems of inconvenience in upper respiratory tract edema examination, untimely drug administration, and lack of detection of the gap between the endotracheal tube and the trachea in the prior art. It simplifies the operation process, reduces the workload of medical staff, and improves the patient's recovery speed.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a nasal cavity insertion endotracheal intubation examination and drug administration device, comprising:

[0009] A drug delivery tube is arranged along the outer tube. One end of the drug delivery tube is fixedly connected to and communicates with a liquid ring. The liquid ring is located at the end of the outer tube near the observation head and is fixedly attached to the inner wall of the outer tube. The liquid ring atomizes the drug solution and sprays it onto the swollen area of ​​the throat.

[0010] Preferably, the observation head includes a hemispherical protective cover, which is transparent and detachably connected to the end of the outer tube; a camera electrically connected to the control device is disposed inside the protective cover, and the camera observes the outside world through the protective cover.

[0011] Preferably, a mounting bracket is provided inside the protective cover, the camera is mounted on the mounting bracket and electrically connected to a first quick slot provided on the mounting bracket, and the first quick slot is electrically connected to the control device through a matching first quick plug.

[0012] Preferably, the liquid ring has a drug delivery chamber that is connected to the drug delivery tube. The drug for disinfecting pharyngeal edema is injected into the drug delivery chamber. The liquid ring has several drug outlet holes that are equally spaced and connected to the drug delivery chamber. Each drug outlet hole has a first one-way module that opens in one direction away from the drug delivery chamber. The drug liquid in the drug delivery chamber is discharged through the one-way opening drug outlet hole and administered to the pharyngeal position.

[0013] Preferably, the first one-way module includes a first one-way plate disposed in the drug outlet, and a plurality of drug delivery holes are provided through the first one-way plate. The drug delivery holes open unidirectionally to the side away from the drug delivery chamber, and the drug delivery holes are connected to an atomizing nozzle disposed on the first one-way plate.

[0014] Preferably, the liquid ring has an annular suction chamber, which is connected to the outside through a suction tube arranged along the outer tube; the suction chamber is connected to the outside through a plurality of equally spaced inlet holes on the liquid ring, and a second one-way module that opens one-way to the suction chamber is provided in the inlet hole.

[0015] Preferably, the second one-way module includes a second one-way plate disposed in the liquid inlet, and a plurality of suction holes are provided through the second one-way plate. A second one-way valve is provided in the suction hole and opens one-way to the suction chamber. Liquid in the patient's throat is drawn in through the one-way opening suction hole.

[0016] Preferably, the outer tube has a plurality of first through holes and second through holes, the first through holes being corresponding to and connected to the drug outlet hole, and the second through holes being corresponding to and connected to the liquid inlet hole.

[0017] Preferably, the control device includes an operating handle, which is detachably connected to one end of the outer tube; a flexible wire harness is electrically connected to the operating handle, which is arranged along the inner cavity of the outer tube and electrically connected to the first quick slot through a first quick plug.

[0018] Preferably, the control device further includes a reversing cylinder, which is electrically connected to the operating handle via the flexible wiring harness; the reversing cylinder is disposed at one end of the outer tube that extends into the body, and is used to guide the end of the outer tube to move along the patient's nasal cavity.

[0019] Compared with existing technologies, this invention has the following advantages and technical effects: This invention discloses a nasal cavity-inserted endotracheal intubation examination and drug delivery device, integrating upper respiratory tract edema examination and drug delivery functions into one device. Medical staff only need to use this one device to complete multiple operations, greatly simplifying the operation process and reducing the workload of medical staff. The flexible design of the outer tube of this invention allows one end to be inserted into the patient's nasal cavity and into the pharynx, while the other end is located outside the patient and electrically connected to the control device. This allows the outer tube to adapt to the physiological structure from the nasal cavity to the pharynx, ensuring smooth insertion and transmitting internal information to the external control device. The observation head is located at the end of the outer tube that extends into the patient's body and is electrically connected to the control device, enabling direct observation of the pharyngeal area. It can obtain information about the patient's pharyngeal area and feed it back to the control device, facilitating medical staff to observe and confirm whether edema, fluid accumulation, or leakage occurs.

The medication delivery tube is arranged along the outer tube, with one end fixedly connected to and connected to a liquid ring. The liquid ring is located at the end of the outer tube near the observation head and is fixedly attached to the inner wall of the outer tube. When edema is detected, the medication can be atomized and sprayed onto the edematous area of ​​the throat, achieving precise medication delivery. This allows for precise drug administration and treatment simultaneously with examination, avoiding time delays during equipment replacement and facilitating rapid patient recovery. Furthermore, if the endotracheal tube shifts or there is a gap between the tube and the tracheal wall after intubation, it can interfere with the patient's normal respiratory function, causing serious complications such as respiratory distress and suffocation, and may also increase the risk of aspiration and lung infections. This invention, by timely examination of the throat, can prevent problems such as tube shifting, while simultaneously alleviating edema through medication, reducing the occurrence of complications, ensuring patient respiratory safety, and improving treatment effectiveness. In addition, the outer tube of this device can be easily and flexibly disassembled from the observation head and control equipment for convenient internal and external sterilization; different lengths and specifications of outer tubes can also be replaced according to usage needs, making it more versatile. During operation, when the external tube is inserted, the observation head guides the insertion. After being inserted into the patient's throat, the observation head first collects data on the edema of the throat and the gap between the endotracheal tube and the external tube. After the data is transmitted to the control device, medical staff determine whether medication is needed and the dosage based on the visualized information. Then, the medication is delivered to the liquid ring through the medication tube. After being atomized by the liquid ring, it is precisely applied to the edematous area. The monitoring and treatment can be completed without changing the equipment. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 7 As shown, this embodiment provides a nasal cavity-inserted endotracheal intubation examination and drug delivery device, comprising:

[0032] The outer tube 1 is flexibly designed. When in use, one end of the outer tube 1 is inserted from the patient's nasal cavity into the throat, and the other end is located outside the patient's body and electrically connected to the control device 4.

[0033] Observation head 2 is located at the end of the outer tube 1 that extends into the patient's body, and observation head 2 is electrically connected to control device 4;

[0034] The administration tube 3 is arranged along the outer tube 1. One end of the administration tube 3 is fixedly connected to and connected to a liquid ring 31. The liquid ring 31 is located at the end of the outer tube 1 near the observation head 2 and is attached to and fixedly connected to the inner wall of the outer tube 1. The liquid is atomized and sprayed onto the edematous area of ​​the throat through the liquid ring 31.

[0035] This invention discloses a nasal-insertable endotracheal intubation and drug delivery device, integrating upper respiratory tract edema examination and drug delivery functions into one device. Medical staff can complete multiple operations using only this one device, greatly simplifying the operation process and reducing the workload of medical staff. The flexible design of the outer tube 1 allows one end to be inserted into the patient's nasal cavity and into the throat, while the other end is located outside the patient and electrically connected to the control device 4. This enables the outer tube 1 to adapt to the physiological structure from the nasal cavity to the throat, facilitating smooth insertion and transmitting internal information to the external control device 4. The observation head 2 is located at the end of the outer tube 1 that extends into the patient's body and is electrically connected to the control device 4, allowing direct observation of the throat area. It can obtain information about the patient's throat and feed it back to the control device 4, facilitating medical staff's observation and confirmation of issues such as edema, fluid accumulation, and leakage. This addresses the shortcomings of traditional methods that require multiple devices and may miss the optimal examination time, improving the timeliness and accuracy of the examination and facilitating the development of subsequent treatment plans. The drug delivery tube 3 is arranged along the outer tube 1, with one end fixedly connected to and connected to a liquid ring 31. The liquid ring 31 is located at the end of the outer tube 1 near the observation head 2 and is fixedly attached to the inner wall of the outer tube 1. When edema is detected, the drug solution can be atomized and sprayed onto the edematous area of ​​the throat, achieving precise drug delivery. This allows for precise drug delivery and treatment during examination, avoiding time delays during equipment replacement and facilitating rapid patient recovery. Furthermore, if the endotracheal tube shifts or there is a gap between the tube and the tracheal wall after intubation, it can interfere with the patient's normal respiratory function, causing serious complications such as respiratory distress and suffocation, and may also increase the risk of aspiration and lung infections. This invention, by timely examination of the throat, can prevent problems such as tube shifting, while simultaneously alleviating edema through drug delivery, reducing the occurrence of complications, ensuring patient respiratory safety, and improving treatment effectiveness. In addition, the outer tube 1 of this device can be easily and flexibly disassembled from the observation head 2 and control device 4 for convenient internal and external disinfection; different lengths and specifications of the outer tube 1 can also be replaced according to usage needs, making it more versatile. During operation, when the external tube 1 is inserted, the observation head 2 guides the insertion of the external tube 1. After it is inserted into the patient's throat, the observation head 2 first collects data on the edema of the throat and the gap between the endotracheal tube and the external tube. After the data is transmitted to the control device 4, the medical staff determines whether medication is needed and the dosage based on the visualized information. Then, the medication is delivered to the liquid ring 31 through the medication tube 3. After being atomized by the liquid ring 31, it is precisely applied to the edematous site. The monitoring and treatment can be completed without changing the equipment.

[0036] In one embodiment of the present invention, the surface of the outer tube 1 is coated with a hydrophilic coating to reduce insertion friction resistance and improve patient comfort during insertion.

[0037] Further optimizing the design, the observation head 2 includes a hemispherical protective cover 21. The protective cover 21 is transparent and detachably connected to the end of the outer tube 1. Inside the protective cover 21 is a camera 22 electrically connected to the control device 4, which observes the outside world through the protective cover 21. The transparent protective cover 21 protects the camera 22 from contamination and damage by the patient's internal secretions. At the same time, the transparent protective cover 21 does not affect the observation effect of the camera 22, improving the clarity and accuracy of the observation. The detachable design between the protective cover 21 and the outer tube 1 facilitates cleaning and disinfection of the protective cover 21, ensuring the hygiene and safety of the device. During operation, the camera 22 is activated first. When the external tube 1 is inserted into the patient's body, the camera 22 assists medical staff in guiding the insertion of the external tube 1. After the head 2 reaches the throat position, the condition of the throat area is observed through the transparent protective cover 21 inside the protective cover 21, and the image information is transmitted to the control device 4 to confirm whether there is water or phlegm accumulation in the throat area, whether there is edema, and whether there is a gap between the endotracheal tube and the trachea, so as to provide support for the formulation of subsequent treatment plans.

[0038] In one embodiment of the present invention, a connecting groove 12 is provided at one end of the outer tube 1 inserted into the body, and a first connecting screw 13 with internal threads is provided in the connecting groove 12. A second connecting screw 25 corresponding to the first connecting screw 13 is provided on the protective cover 21. The protective cover 21 can be quickly installed and removed through the first connecting screw 13 and the second connecting screw 25.

[0039] The design is further optimized by installing a mounting bracket 23 inside the protective cover 21. The camera 22 is mounted on the mounting bracket 23 and electrically connected to a first quick-connect slot 24 located on the mounting bracket 23. The first quick-connect slot 24 is electrically connected to the control device 4 via a matching first quick-connect plug 44. The camera 22 is fixed to the mounting bracket 23 and can be quickly connected and disconnected from the control device 4 via the first quick-connect slot 24 and the first quick-connect plug 44. When it is necessary to replace the camera 22 or perform maintenance, the first quick-connect plug 44 can be quickly plugged and unplugged to disconnect from the control device 4, improving the maintenance efficiency of the device and reducing time delays caused by equipment maintenance. Simultaneously, before equipment assembly, the camera 22 and the outer tube 1 can be conveniently stored and placed separately, effectively preventing damage to the camera 22 or the protective cover 21 from impacts.

[0040] In one embodiment of the present invention, the control signal of the control device 4 is transmitted through the first quick plug 44 and the first quick slot 24, thereby controlling the rotation of the camera 22 to achieve observation from different angles and improve the accuracy of judging the position of the patient's larynx.

[0041] Further optimizing the design, a drug delivery chamber 33 is formed within the liquid ring 31, which is connected to the drug delivery tube 3. The drug used for disinfecting pharyngeal edema is injected into the drug delivery chamber 33. Several drug outlet holes 34, evenly spaced on the liquid ring 31 and connected to the drug delivery chamber 33, are provided. Each drug outlet hole 34 has a first one-way module 35 that opens unidirectionally away from the drug delivery chamber 33. The drug solution in the drug delivery chamber 33 is discharged through the one-way opening drug outlet hole 34 and administered to the pharynx. The liquid ring 31 is annularly attached to the inner wall of the outer tube 1. The drug delivery chamber 33 is formed along the structure of the liquid ring 31. After the drug is injected into the drug delivery chamber 33 through the drug delivery tube 3, the drug solution is discharged through the drug outlet hole 34 under pressure. Because the drug outlet hole 34 has the first one-way module 35, the drug solution can only be discharged unidirectionally, preventing backflow and ensuring directional discharge of the drug solution. This avoids contamination and waste caused by backflow, improving the accuracy and effectiveness of drug administration.

[0042] Further optimizing the design, the first one-way module 35 includes a first one-way plate 36 disposed in the drug outlet 34. Several drug delivery holes 37 are perforated on the first one-way plate 36, opening unidirectionally to the side furthest from the drug delivery chamber 33. The drug delivery holes 37 are connected to an atomizing nozzle 38 disposed on the first one-way plate 36. After the medication enters the drug delivery chamber 33, it passes through the drug delivery holes 37 on the first one-way plate 36. Due to the presence of a first one-way valve 39 within each drug delivery hole 37, the hole opens unidirectionally, allowing the medication to flow only outwards. After being atomized by the atomizing nozzle 38, the medication is sprayed onto the swollen area of ​​the throat, enabling more even distribution of the medication at the swollen site, improving the therapeutic effect of the drug, and simultaneously reducing the dosage.

[0043] The design is further optimized by establishing a ring-shaped suction chamber 310 within the liquid ring 31. The suction chamber 310 is connected to the outside via a suction tube 316 arranged along the outer tube 1. The suction chamber 310 is also connected to the outside via several equally spaced inlet holes 311 on the liquid ring 31. Each inlet hole 311 contains a second unidirectional module 312 that opens unidirectionally into the suction chamber 310. The suction chamber 310 is structured along the liquid ring 31 and is independent of the drug delivery chamber 33. When fluid or sputum is found in the patient's throat, the suction tube 316, which is connected to the suction gun and arranged along the outer tube 1, is connected to the suction device. The suction device draws in negative pressure within the suction chamber 310, causing fluid from the patient's throat to enter the suction chamber 310 through the inlet holes 311. Because the inlet hole 311 is equipped with a second one-way module 312, the liquid can only enter the suction chamber 310 in one direction, preventing liquid backflow and avoiding contamination caused by liquid backflow. At the same time, it can effectively attract the liquid in the patient's throat, reduce the risk of aspiration, and reduce the probability of lung infection.

[0044] In one embodiment of the present invention, it is necessary to drain the effusion or phlegm in the throat before administering the medication to improve the therapeutic effect of the drug and at the same time avoid exacerbating edema caused by phlegm or effusion.

[0045] In one embodiment of the present invention, an arrangement groove 11 is provided on the inner wall of the outer tube 1. After the administration tube 3 and the aspiration tube 316 are bundled and fixed, they are installed in the arrangement groove 11 until they extend out of the outer tube 1 and are then separated and connected to different devices.

[0046] Further optimizing the design, the second one-way module 312 includes a second one-way plate 313 disposed within the inlet port 311. Several suction holes 314 are perforated on the second one-way plate 313, and each suction hole 314 contains a second one-way valve 315 that opens unidirectionally into the suction chamber 310. Liquid in the patient's throat is drawn in through the one-way suction holes 314. Under the negative pressure of the suction chamber 310, accumulated fluid or phlegm in the patient's throat enters the suction chamber 310 through the suction holes 314 on the second one-way plate 313. Because the suction holes 314 contain the second one-way valve 315, accumulated fluid or phlegm can only enter the suction chamber 310 in one direction, preventing backflow and improving the accuracy and reliability of suction. This effectively prevents contamination and damage to the device caused by backflow.

[0047] Further optimizing the design, the outer tube 1 has several first through holes 14 and second through holes 15. The first through holes 14 are correspondingly arranged and connected to the drug outlet 34, and the second through holes 15 are correspondingly arranged and connected to the liquid inlet 311. The first through holes 14 and second through holes 15 enable communication between the inside and outside of the outer tube 1. At the same time, the drug outlet 34 is correspondingly arranged and sealed to the first through hole 14, and the liquid inlet 311 is correspondingly arranged and sealed to the second through hole 15, so that the drug delivery chamber 33 and the suction chamber 310 are respectively connected to the outside of the outer tube 1, facilitating suctioning or liquid suctioning and drug administration to the patient's throat.

[0048] Further optimizing the design, the control device 4 includes an operating handle 41, which is detachably connected to one end of the outer tube 1. A flexible wire harness 43 is electrically connected to the operating handle 41, arranged along the inner cavity of the outer tube 1 and electrically connected to the first quick-connect slot 24 via a first quick-connect plug 44. As a handheld operating device, one end of the operating handle 41 is electrically connected to a fixed display and large equipment, while the other end is electrically connected to a camera 22 via the flexible wire harness 43 arranged along the outer tube 1. Commands are output to the camera 22 via the operating buttons 42 on the operating handle 41, controlling the camera 22 to observe from different angles and transmit the observed images to the fixed display, facilitating medical personnel's assessment of the patient's throat position. The detachable connection between the operating handle 41 and the outer tube 1 allows for easy replacement of different outer tubes 1 and associated structures, making it more flexible in use. The flexible wire harness 43 is located inside and along the outer tube 1, preventing contact between the flexible wire harness 43 and the patient's body, improving patient protection and facilitating subsequent cleaning and disinfection.

[0049] In one embodiment of the present invention, a second quick slot 47 is provided at the end of the operating handle 41 away from the fixed display, and a second quick plug 46 is provided at the end of the flexible wire harness 43, so as to realize quick connection and disconnection between the flexible wire harness 43 and the operating handle 41.

[0050] In one embodiment of the present invention, a toothed connector 48 corresponding to the outer tube 1 is provided on the side of the second quick plug 46 away from the second quick slot 47, and the outer tube 1 is connected to the second quick plug 46 through the toothed connector 48.

[0051] In one embodiment of the present invention, a positioning point 49 is provided on the second quick plug 46, and a positioning groove corresponding to the positioning point 49 is provided in the second quick slot 47, so as to facilitate the accurate connection between the second quick plug 46 and the second quick slot 47.

[0052] To further optimize the design, the control device 4 also includes a reversing cylinder 45, which is electrically connected to the operating handle 41 via a flexible wiring harness 43. The reversing cylinder 45 is located at the end of the outer tube 1 that extends into the body, guiding the end of the outer tube 1 along the patient's nasal cavity. The reversing cylinder 45, located at the end of the outer tube 1 inserted into the patient's body and connected to the operating handle 41 via the flexible wiring harness 43, allows the reversing cylinder 45 to bend and twist at different angles by inputting different electrical signals through the operating handle 41. This, in turn, causes the outer tube 1 to bend. Medical personnel control the movement of the reversing cylinder 45 through the operating handle 41, guiding the end of the outer tube 1 to move within the patient's nasal cavity, enabling the device to accurately reach the target position. This improves the device's positioning accuracy, reduces operational difficulty, further ensures the accuracy of the endotracheal intubation position, and lowers the risk of complications. Simultaneously, the reversing cylinder 45, by moving the end of the outer tube 1 to the patient's throat position, expands the observation range of the camera 22, providing a comprehensive understanding of the patient's throat position.

[0053] In one embodiment of the present invention, the commutator 45 may be an electromuscular bundle. When a voltage is applied to one of the fibers, the difference in the contraction rate of each fiber within the bundle causes the fiber to curl, and this curling behavior becomes more pronounced as the voltage increases. Furthermore, each fiber in the bundle can be independently controlled, and through a reasonable control strategy, bending at different angles can be achieved.

[0054] In one embodiment of the present invention, the commutator 45 may employ a dielectric elastomer actuator, the basic structure of which consists of a dielectric film sandwiched between flexible electrodes, achieving mechanical movement through electrostatic force. The actuator's separable characteristics can be achieved through electrode design, thus enabling bending at various angles by controlling the electrodes in different regions. Furthermore, artificial muscles based on liquid metal flexible electrodes and electroactive polymer materials can also be formed by placing and combining them in different directions in three-dimensional space, creating complex artificial muscle tissue capable of deformation or bending in multiple directions.

[0055] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0056] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
