Description

An oropharyngeal ventilation device for anesthesiology based on oxygen delivery tube Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an oropharyngeal ventilation device for anesthesiology based on an oxygen delivery tube. Background Technology

[0002] In clinical anesthesiology, oropharyngeal ventilation devices are key medical devices for ensuring stable respiratory function in patients. They are widely used in general anesthesia, emergency resuscitation, and other scenarios. Their core function is to establish an artificial airway, open the relaxed soft tissues of the oropharynx (such as the tongue and soft palate), prevent airway obstruction, and at the same time provide sufficient oxygen to the patient in conjunction with oxygen delivery, maintain normal gas exchange, and ensure the respiratory safety of patients during anesthesia and postoperative recovery.

[0003] With the development of anesthesia techniques and the increasing demands of clinical practice, higher requirements have been placed on the functional integrity and safety of oral ventilation devices. On the one hand, under anesthesia, patients' swallowing and coughing reflexes are weakened, and secretions such as saliva and sputum are easily produced in the oropharynx. If these secretions are not detected and cleared in time, they can easily lead to airway obstruction, causing risks such as hypoxia and suffocation. On the other hand, if there is a lack of effective lubrication during device insertion, it can easily rub against the larynx mucosa, causing mucosal damage and increasing postoperative discomfort for patients. In addition, if the device is not fixed stably during use, it can easily shift due to patient agitation or swallowing movements, leading to ventilation interruption and affecting the treatment effect.

[0004] Existing oropharyngeal ventilation technologies still have significant shortcomings. Some existing devices do not effectively distinguish between ventilation and oxygen delivery functions, which can easily lead to airflow interference, resulting in unstable oxygen concentration or decreased ventilation efficiency, and failing to ensure normal gas exchange for patients. Summary of the Invention

[0005] In view of the fact that some existing devices do not effectively distinguish between ventilation and oxygen delivery functions, which can easily lead to mutual interference of airflow, resulting in unstable oxygen concentration or decreased ventilation efficiency and failing to ensure normal gas exchange for patients, the purpose of this invention is to provide an oropharyngeal ventilation device for anesthesiology based on an oxygen delivery tube.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An oropharyngeal ventilation device for anesthesiology based on an oxygen delivery tube includes a tube body with a partitioning mechanism, a lubrication component disposed on the tube body to allow saline solution to overflow, a detection component disposed at one end of the tube body located inside the patient's larynx, and a suction component disposed within the tube body to aspirate secretions.

[0008] Optionally, the partitioning mechanism includes a partition support plate fixedly installed inside the pipe, which divides the pipe into a ventilation chamber and an oxygen supply chamber.

[0009] Optionally, the lubrication assembly includes a flow cavity on a tube body, an overflow hole on the tube body communicating with the flow cavity, a first connecting block fixedly installed on the tube body, an inlet tube fixedly installed on the first connecting block, and the inlet tube communicating with the flow cavity and connected to a saline syringe.

[0010] Optionally, a support assembly is provided on the tube body. The support assembly includes a second connecting block fixedly installed on the tube body, an air inlet pipe fixedly installed on the second connecting block, an air chamber communicating with the air inlet pipe being opened inside the tube body, a connecting air passage being opened inside the partition support plate, a movable groove being opened inside the partition support plate, an airbag communicating with the connecting air passage being fixedly installed in the movable groove, and sliders being fixedly installed at both ends of the airbag, with supporting arc plates fixedly installed on each slider.

[0011] Optionally, a first spring is fixedly installed inside the airbag, and the first spring is used to drive the airbag to contract.

[0012] Optionally, an arched frame is fixedly installed inside the second connecting block, a movable column is slidably installed on the arched frame, a sealing plug that is slidably and sealingly connected to the air intake pipe is fixedly installed on the movable column, a second spring is fixedly installed on the sealing plug, and the end of the second spring away from the sealing plug is fixedly connected to the arched frame.

[0013] Optionally, the detection component includes an installation cavity formed within a partition support plate, wherein a humidity sensor for detecting secretions is disposed within the installation cavity, and a through hole communicating with the ventilation chamber and the oxygen supply chamber is provided within the installation cavity.

[0014] Optionally, the suction assembly includes a pair of suction chambers formed on the tube body, each suction chamber having a pair of suction holes communicating with the ventilation chamber and the oxygen supply chamber, and a connecting end fixedly installed on the tube body communicating with the suction chamber, the connecting end communicating with the suction gas source.

[0015] Optionally, the tube body is provided with a fixing component, the fixing component including a bite pad, the bite pad being provided with an adaptation groove adapted to the teeth.

[0016] Optionally, an extension plate is fixedly mounted on the bite pad, and a fixing bolt is threaded onto the extension plate.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a partitioning mechanism, the partitioning mechanism first constructs an independent gas flow path in the tube, which respectively ensures the patient's normal ventilation (exhalation of carbon dioxide and inhalation of air) and stable oxygen supply, avoids mutual interference between ventilation and oxygen delivery flow, and ensures the integrity of the respiratory cycle.

[0019] By incorporating a lubrication component, saline solution is actively released during the insertion of the tube into the patient's larynx, reducing frictional resistance between the tube and the larynx mucosa, minimizing scratching damage to the mucosa during insertion, improving the smoothness of the insertion procedure, and alleviating postoperative throat discomfort for the patient.

[0020] The detection component, installed at the end of the tube that extends into the patient's throat, can monitor in real time whether secretions (such as saliva or phlegm) accumulate in the throat and block the tube, promptly capturing the risk signal of blockage and preventing ventilation / oxygen delivery interruption due to secretion blockage.

[0021] The suction component is linked with the detection component. When the detection component detects secretions blocking the tube, the suction component can quickly start the suction and separation operation to clear the blockage, restore the tube's patency, and ensure the continuous and stable ventilation and oxygen delivery functions.

[0045] As shown in Figures 1 to 8, this embodiment of the invention provides an oropharyngeal ventilation device for anesthesiology based on an oxygen delivery tube, including a tube body 10. A partitioning mechanism 20 is provided on the tube body 10, which is disposed within the tube body 10 to ensure smooth ventilation and oxygen supply to the patient. A lubrication assembly 30 is disposed on the tube body 10, which is used to release lubricating saline solution when the tube body 10 is inserted into the patient's larynx. A detection assembly 50 is disposed at one end of the tube body 10 located within the patient's larynx, which is used to detect whether there are secretions blocking the tube body 10 in the patient's larynx. A suction assembly 60 is disposed within the tube body 10, which is used in conjunction with the detection assembly 50 to suction and separate secretions.

[0046] In use, this invention first establishes independent gas flow paths within the tube 10 via the partitioning mechanism 20, ensuring normal ventilation (expelling carbon dioxide and inhaling air) and stable oxygen supply for the patient, avoiding interference between ventilation and oxygen delivery flow, and ensuring the integrity of the respiratory cycle. Secondly, during insertion of the tube 10 into the patient's larynx, the lubrication component 30 actively releases lubricating saline solution, reducing frictional resistance between the tube 10 and the larynx mucosa, minimizing scratching damage to the mucosa during insertion, improving the smoothness of the insertion procedure, and simultaneously alleviating postoperative throat discomfort for the patient. Furthermore, the detection component 50 is installed at the end of the tube 10 that extends into the patient's throat, which can monitor in real time whether there is any accumulation of secretions (such as saliva or phlegm) in the throat that may block the tube 10, and promptly capture the risk signal of blockage to avoid ventilation / oxygen delivery interruption due to secretion blockage; finally, the suction component 60 is linked with the detection component 50. When the detection component 50 detects secretion blockage, the suction component 60 can quickly start the suction and separation operation of the secretions to clear the blockage, restore the patency of the tube 10, and ensure the continuous and stable ventilation and oxygen delivery functions.

[0047] As shown in Figures 3 and 4, the partitioning mechanism 20 includes a partition support plate 23 fixedly installed inside the tube body 10. The partition support plate 23 divides the tube body 10 into a ventilation chamber 21 and an oxygen supply chamber 22. The partitioning mechanism 20 physically divides the internal space of the tube body 10 into independent ventilation chambers 21 and oxygen supply chambers 22 by fixing the partition support plate 23 inside the tube body 10. The ventilation chamber 21 serves as the main channel for gas exchange, responsible for expelling carbon dioxide exhaled by the patient and introducing outside air or a mixed gas delivered by the ventilator. The oxygen supply chamber 22 is specifically used to deliver high-concentration oxygen, directly delivering oxygen to the vicinity of the patient's oropharynx. This physical partitioning design can strictly distinguish between the ventilation airflow and the oxygen delivery airflow, preventing the two airflows from mixing inside the tube body 10, which would lead to unstable oxygen concentration or decreased ventilation efficiency. This ensures that the patient can obtain sufficient oxygen supply and achieve normal gas exchange, maintaining stable respiratory function.

[0048] As shown in Figures 3 and 4, the lubrication assembly 30 includes a flow cavity 33 on a tube body 10, an overflow hole 34 communicating with the flow cavity 33 on the tube body 10, a first connecting block 31 fixedly installed on the tube body 10, an inlet pipe 32 fixedly installed on the first connecting block 31, one end of the inlet pipe 32 communicating with the flow cavity 33, and the other end connected to a saline syringe;

[0049] When the tube 10 needs to be inserted into the patient's larynx, the medical staff pushes the piston of the saline syringe. The saline enters the flow chamber 33 through the inlet tube 32, and then overflows evenly onto the surface of the tube 10 through multiple overflow holes 34. The overflowing saline forms a lubricating layer between the tube 10 and the larynx mucosa, which significantly reduces the frictional resistance when the tube 10 is inserted, avoids the tube 10 from scratching or damaging the larynx mucosa, reduces the patient's pain during the insertion process, and improves the smoothness of the insertion operation, reducing the operational risks caused by insertion difficulties.

[0050] As shown in Figures 3 and 4, a support assembly 40 is provided on the tube body 10. The support assembly 40 includes a second connecting block 41 fixedly installed on the tube body 10. An air inlet pipe 42 is fixedly installed on the second connecting block 41. An air chamber 44 communicating with the air inlet pipe 42 is opened inside the tube body 10. A connecting air passage 45 is opened inside the partition support plate 23. A movable groove 46 is opened inside the partition support plate 23. An airbag 47 communicating with the connecting air passage 45 is fixedly installed in the movable groove 46. A slider 48 is fixedly installed at both ends of the airbag 47. A support arc plate 49 is fixedly installed on each slider 48.

[0051] After the tube 10 is inserted into the patient's larynx, medical staff introduce gas into the air chamber 44 through the air inlet tube 42. The gas passes through the air chamber 44 and the connecting airway 45 into the air bag 47. After the air bag 47 is inflated, its volume expands, pushing the sliders 48 at both ends to slide radially outward along the tube 10 within the movable groove 46. The sliders 48 drive the supporting arc plate 49 to unfold outward simultaneously. The unfolded supporting arc plate 49 contacts the inner wall of the patient's larynx and forms a supporting force, stably fixing the tube 10 in the larynx. This prevents the tube 10 from shifting or slipping due to the patient's swallowing, agitation, or other actions, ensuring that the ventilation chamber 21 and the oxygen supply chamber 22 remain unobstructed at all times, and avoiding the normal use of the equipment due to the displacement of the tube 10.

[0052] As shown in Figures 5 and 7, a first spring 410 is fixedly installed inside the airbag 47. The end of the first spring 410 is connected to the inner wall of the airbag 47 near the supporting arc plate 49. The first spring 410 is used to drive the airbag 47 to contract.

[0053] The first spring 410 can cause the airbag 47 to contract under its own elastic restoring force. As the volume of the airbag 47 decreases, the pushing force on the slider 48 disappears. Under the slight pressure of the inner wall of the throat or its own gravity, the slider 48 slides along the movable groove 46 toward the center of the tube body 10, thereby causing the support arc plate 49 to retract. The setting of the first spring 410 can realize the automatic contraction of the airbag 47 without additional manual operation, simplifying the retraction process of the support arc plate 49, improving the convenience of operation, and ensuring that the airbag 47 contracts completely, avoiding the support arc plate 49 from getting stuck in the throat due to the airbag 47 not being fully contracted, reducing the risk when the tube body 10 is pulled out or adjusted.

[0054] As shown in Figure 6, an arched frame 411 is fixedly installed inside the second connecting block 41. A movable column 412 is slidably installed on the arched frame 411. A sealing plug 414 that is slidably and sealingly connected to the air intake pipe 42 is fixedly installed on the movable column 412. A second spring 413 is fixedly installed on the sealing plug 414. The end of the second spring 413 away from the sealing plug 414 is fixedly connected to the arched frame 411.

[0055] The second spring 413, in its naturally extended state, pushes the sealing plug 414 to tightly adhere to the inner wall of the air intake pipe 42, thus sealing the air intake pipe 42 and preventing gas leakage from the air chamber 44. This ensures that the airbag 47 can maintain a stable inflation state and maintain the supporting force of the supporting arc plate 49. When air needs to be supplied to the air chamber 44, external gas applies pressure through the air intake pipe 42, overcoming the elastic force of the second spring 413 and pushing the sealing plug 414 to slide along the arch frame 411. The sealing plug 414 separates from the inner wall of the air intake pipe 42, allowing gas to smoothly enter the air chamber 44. When air supply stops, the elastic force of the second spring 413 pushes the sealing plug 414 back to its original position, resealing the air intake pipe 42. This prevents gas leakage from the air chamber 44 from causing the airbag 47 to contract and the supporting arc plate 49 to shift, ensuring the stability of the supporting assembly 40. As shown in Figure 6, when deflation occurs, a long strip of external material is used to press against the sealing plug 414, causing it to move upward and compress the second spring 413.

[0056] As shown in Figure 5, the detection component 50 includes an installation cavity 51 opened in the partition support plate 23, a humidity sensor 52 for detecting secretions is provided in the installation cavity 51, and a through hole 53 communicating with the ventilation chamber 21 and the oxygen supply chamber 22 is opened in the installation cavity 51.

[0057] If secretions (such as saliva or phlegm) in the patient's throat block the ventilation chamber 21 or oxygen supply chamber 22, they will enter the installation cavity 51 through the through hole 53. The humidity sensor 52 can detect the humidity change in the installation cavity 51 in real time. Since the humidity of the secretions is much higher than that of normal airflow, when the humidity sensor 52 detects that the humidity value exceeds the preset threshold, it will send an electrical signal to remind medical staff that there is a risk of secretion blockage in the tube 10. This can achieve early warning of blockage, avoid excessive accumulation of secretions leading to interruption of ventilation or oxygen supply, buy time for medical staff to deal with the blockage in a timely manner, and reduce the respiratory risk caused by blockage.

[0058] As shown in Figures 3 and 5, the suction assembly 60 includes a pair of suction chambers 61 opened on the tube body 10. Each suction chamber 61 has a pair of suction holes 62 that communicate with the ventilation chamber 21 and the oxygen supply chamber 22. A connecting end 63 that communicates with the suction chamber 61 is fixedly installed on the tube body 10. The connecting end 63 is connected to the suction gas source.

[0059] When the detection component 50 (humidity sensor 52) indicates the presence of secretions causing blockage, medical staff activate the suction air source, creating negative pressure in the suction chamber 61. Secretions in the ventilation chamber 21 and oxygen supply chamber 22 are drawn into the suction chamber 61 through the corresponding suction port 62, and then discharged through the connection end 63 into the suction air source. This component can quickly and accurately clear secretions in the ventilation chamber 21 and oxygen supply chamber 22, preventing secretions from blocking the channels, restoring ventilation and oxygen delivery functions, and completing the suction operation without removing the tube 10, reducing interference with the patient and lowering operational risks.

[0060] As shown in Figure 8, a fixing component 70 is provided on the tube body 10. The fixing component 70 includes a bite pad 71, and the bite pad 71 is provided with an adaptation groove 72 that adapts to the teeth.

[0061] After the tube 10 is inserted into the patient's oropharynx, the bite pad 71 is placed between the patient's teeth. The patient's teeth are embedded in the fitting slot 72. The fitting slot 72 can restrict the range of motion of the teeth and prevent the patient from unconsciously biting the tube 10 during the anesthesia recovery process, thus ensuring the unobstructed flow of the ventilation chamber 21 and the oxygen supply chamber 22. At the same time, the bite pad 71 can also play an auxiliary role in fixing the tube 10, further preventing the tube 10 from shifting in the patient's oral cavity, improving the overall stability of the device, and ensuring the continuous ventilation and oxygen delivery.

[0062] As shown in Figure 8, an extension plate 73 is fixedly installed on the bite pad 71, and a fixing bolt 74 is threaded onto the extension plate 73. After the positions of the tube body 10 and the bite pad 71 are adjusted, the fixing bolt 74 is rotated to make it abut against the tube body 10, thereby fixing the bite pad 71. After loosening the fixing bolt 74, the position of the bite pad 71 can be adjusted to suit different users.

[0063] The specific workflow of the technical solution provided by this invention is as follows:

[0064] Before use, connect the inlet tube 32 to the saline syringe and push the syringe to allow the saline to overflow through the flow chamber 33 and overflow hole 34 onto the surface of the tube 10, forming a lubricating layer. Then, the medical staff holds the tube 10 and slowly inserts the end with the lubricating layer into the patient's larynx. During the insertion process, the lubricating layer reduces the friction between the tube 10 and the larynx mucosa, avoiding damage. At the same time, the patient's teeth are inserted into the fitting groove 72 of the bite pad 71 to initially fix the tube 10.

[0065] After the tube 10 is inserted into place, gas is introduced into the air chamber 44 through the air inlet pipe 42. The gas enters the air bag 47 through the connecting airway 45. The air bag 47 inflates and pushes the slider 48 to drive the support arc plate 49 to unfold outward. The support arc plate 49 contacts the inner wall of the throat tube to form support, thus stabilizing and fixing the tube 10.

[0066] The partition support plate 23 divides the tube body 10 into a ventilation chamber 21 and an oxygen supply chamber 22. The ventilation chamber 21 is connected to the ventilator or outside air to realize the exchange of carbon dioxide exhaled by the patient with inhaled air. The oxygen supply chamber 22 is connected to an oxygen source to deliver high-concentration oxygen to the patient's oropharynx. The two operate independently to ensure sufficient oxygen supply and normal gas exchange.

[0067] Humidity sensor 52 inside the installation cavity 51 monitors the humidity in the ventilation chamber 21 and oxygen supply chamber 22 in real time through through hole 53. When secretions (saliva, sputum) enter the installation cavity 51 through through hole 53, humidity sensor 52 detects that the humidity exceeds the standard and issues a blockage warning. Medical staff start the suction air source and create negative pressure in suction chamber 61 through connection end 63. Secretions are sucked into suction chamber 61 through suction hole 62 and discharged, restoring the passage to unobstructed flow.

[0068] When it is necessary to pull out the tube 10 or adjust its position, stop the air supply to the air inlet tube 42. The first spring 410 inside the airbag 47 causes the airbag 47 to contract and the supporting arc plate 49 to retract. At the same time, rotate the fixing bolt 74 in the opposite direction to loosen the clamping pad 71. Then slowly pull out the tube 10 to complete the operation.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
