Description

Technical Field

[0001] The invention relates to the technical field of oropharyngeal ventilation catheters, in particular to an adjustable, visual and intubating oropharyngeal ventilation special-shaped catheter seat. Background Art

[0002] The oropharyngeal airway tube is a key component of a laryngoscope and plays an important role in the medical field, especially in airway management. It is part of a laryngoscope, such as a video laryngoscope. When used, it is inserted into the patient's mouth, providing the doctor with a visual field and assisting with laryngeal examinations, endotracheal intubation, and other procedures. For example, during anesthesia induction, the oropharyngeal airway tube is used to expose the glottis, facilitating endotracheal tube insertion and establishing an artificial airway. It is also used to diagnose laryngeal diseases and observe lesions in the vocal cords, epiglottis, and other areas. The oropharyngeal airway is a traditional airway management tool that can prevent the tongue from falling back and establish an oropharyngeal airway, playing an important role in the medical field, especially in airway management.

[0003] For example, a Chinese patent with authorization announcement number CN109008926B discloses a laryngoscope blade, comprising: a lens body, comprising a proximal end, a distal end and a middle portion located between the proximal end and the distal end, the lens body comprising a curved upper surface and a curved lower surface relative to the upper surface, the proximal end of the lens body having an opening, the opening passing through the middle portion or part of the distal end to form a channel, the channel being used to connect an image acquisition tool; a flange formed by extending from the side edge of the lower surface of the lens body, the flange extending from the middle portion to the proximal end and the distal end respectively, the width of which decreases from the middle portion to the proximal end or the distal end, wherein the flange converges at the proximal end, and the lower surface is used to adhere to the human oral cavity; a bulge located at the distal end of the lower surface, the bulge being used to lift the epiglottis.

[0004] However, both the above patents and the prior art have some problems. Since the patient needs to be anesthetized, the root of the tongue will block the trachea. The existing solution is to use an integrated oropharyngeal airway tube to make this type of oropharyngeal airway abut against the patient's epiglottis to complete the tongue lifting work. Using this method will cause cartilage damage to the patient, causing secondary injury to the patient; at the same time, the tongue size of different patients is different, and the curvature length of the oropharyngeal airway cannot be adjusted to achieve the best tongue root lifting effect; and the effect of tongue root lifting is uncertain, and a monitor needs to be connected to observe vital signs in order to evaluate the effect of tongue root lifting and airway obstruction relief; finally, the closure of the front section of the oropharyngeal airway cannot meet the clinical need for intubation at any time.

[0005] Therefore, how to change the support position of the oropharyngeal ventilation tube to avoid secondary injury to the patient and thus meet the patient's intubation needs is a problem that needs to be solved at present. Summary of the Invention

[0060] In a further embodiment, the driving part 3 and the connecting line can be replaced by a spring sheet, which is located in the lower pressure seat 2. The spring sheet is a U-shaped structure. By changing the shape of the spring sheet, the spring sheet is deformed, thereby driving the lower pressure seat 2 to deform so that it can abut against the root of the patient's tongue. The lower pressure seat 2 can limit the spring sheet, thereby ensuring that the lower pressure seat 2 can contact the root of the tongue.

[0061] In a further embodiment, the driving part 3 and the connecting line can be replaced by an arc-shaped airbag, which is located in the lower pressure seat 2.

The moving adjustment shaft 67 can squeeze the saline solution in the mounting seat 61. When the squeezed saline solution overcomes the elastic force generated by the deformation of the support spring 663, the saline solution can spray water from the water spray seat 63 and enter the patient's body along with the gas, thereby moistening the gas or diluting the sputum in the patient's throat, improving the operator's observation clarity and expanding the operator's field of view.

[0063] The driving member 64 includes a driving tube 643 arranged in the mounting seat 61 and movably connected to the mounting seat 61, a connecting seat 644 arranged on the driving tube 643, a return spring 645 for connecting the connecting seat 644 and the adjusting portion 65, and a plurality of limit plates 642 and a button 641 connected to the driving tube 643 are also provided on the mounting seat 61; the return spring 645 is sleeved on the adjusting shaft 67 and one end of the adjusting shaft 67 is arranged on the connecting seat 644; by pushing the button 641, the adjusting shaft 67 is moved in the mounting seat 61, thereby completing the delivery of physiological saline, and through the cooperation of the set return spring 645 and the limit plate 642, the driving tube 643 is driven without applying external force. 43 can abut against the limit plate 642 to return the device to its initial position; when it is necessary to push and inject saline solution, the button 641 is pressed at this time, and the moving button 641 can drive the driving tube 643 to move, thereby driving the connecting seat 644 to move. The moving connecting seat 644 can change the deformation of the return spring 645 while pushing the adjusting shaft 67 to move. The moving adjusting shaft 67 can complete the injection of saline solution, and after the injection is completed, the elastic force generated by the deformation of the return spring 645 can drive the adjusting shaft 67 to move in the opposite direction. Under the limit of the limit plate 642, the return spring 645 can make the driving tube 643 be in the initial position, thereby ensuring the smooth progress of the next injection of saline solution.

[0064] The adjusting portion 65 includes a delivery tube 651, a control sleeve 672, and a limit plate 653 which are sequentially sleeved on the adjusting shaft 67, a gear 655 sleeved on the control sleeve 672, a driving rod 654 located on the mounting seat 61 and meshing with the gear 655, an annular protrusion 657 provided in the mounting seat 61, and a limit bolt 656 provided on the mounting seat 61; the return spring 645 is connected to the limit plate 653, and the annular protrusion 657 abuts against the control sleeve 652; the gear 655 is rotated by the movement of the driving rod 654, thereby causing the delivery tube 651 to rotate around the adjusting shaft 67, and then the limit bolt 65 6 abuts against the delivery tube 651 to fix the position of the delivery tube 651; when it is necessary to adjust the injection amount of normal saline, the driving rod 654 is pushed to cause relative displacement between the driving rod 654 and the gear 655, thereby driving the gear 655 to rotate, and the moving gear 655 can drive the control sleeve 672 to rotate, and the rotating control sleeve 672 can drive the delivery tube 651 to rotate. Since the adjusting shaft 67 is provided with a spiral groove, the straight-line distance between the spiral groove and the injection port 6511 can be adjusted. By changing the straight-line distance between the two, the injection amount is changed, thereby completing the adjustment of the injection amount of normal saline.

[0065] The image corresponding to the positive projection of the delivery tube 651 is a convex structure, in which the area with a larger diameter is closer to the water inlet 62 than the area with a smaller diameter. There is a certain gap between the area with a larger diameter of the delivery tube 651 and the inner wall of the mounting seat 61. The gap is the delivery cavity 6512 for storing physiological saline, and the inside of the delivery tube 651 is connected to the delivery cavity 6512 through the inlet 6511; the output end of the delivery tube 651 is connected to the water outlet 66; the adjusting shaft 67 is provided with a limit block 671 in the axial direction, which is provided at one end of the adjusting shaft 67. The rotating block 676 is sleeved on the sleeve 672 at the other end of the adjusting shaft 67. The sleeve 672 is provided with a first groove 673 and a third groove 675, and a second groove 674 for connecting the first groove 673 and the third groove 675. The length direction of the first groove 673 is parallel to the axial direction of the adjusting shaft 67, the third groove 675 is an annular groove, and the second groove 674 is a spiral groove. The rotating block 676 abuts against the connecting seat 644, and the control sleeve 672 is provided with a sliding groove adapted to the limit block 671.

[0066] When the normal saline solution is injected, the normal saline solution can enter the delivery cavity 6512 along the water inlet 62, and then move into the delivery tube 651 through the provided injection port 6511. Then, the driving member 64 drives the adjusting shaft 67 to move in the delivery tube 651, thereby squeezing the liquid in the delivery tube 651, so that the liquid can be sprayed out from the water spray seat 63 after overcoming the elastic force generated by the deformation of the support spring 663. As the adjusting shaft 67 continues to move, the injection port 6511 is connected to the second groove 674, and the pressure relief work of the liquid is completed. At this time, even if the adjusting shaft 67 continues to move, the liquid cannot overcome the elastic force generated by the deformation of the support spring 663, and the liquid will flow along the first groove 673 and the second groove 674. 4 and the third groove 675 flow into the delivery chamber 6512, thereby preventing excess liquid from being sprayed out from the water spray seat 63 and enabling it to be recovered to avoid waste. After completing the above work, the adjustment shaft 67 is pushed by the return spring 645 to move in the opposite direction, thereby forming a negative pressure between the adjustment shaft 67 and the delivery tube 651. When the adjustment shaft 67 is away from the injection port 6511, the physiological saline solution can be located in the delivery tube 651 under the influence of its own gravity and negative pressure, ensuring the smooth progress of the next physiological saline injection. The adjustment of the physiological saline input amount and the quantitative delivery are completed by mechanical adjustment, without the need to install too many control systems, and the injection work can be completed by pressing.

[0068] Working principle description: When performing throat detection work on a patient, the lower pressure seat 2 in the device is inserted into the patient's throat, and then the adjusting knob 32 is rotated to drive the connecting sleeve 33 to rotate. The moving connecting sleeve 33 drives the connecting ear 34 to rotate, so that the connecting wire can be wound around the connecting sleeve 33, changing the length of the connecting wire in the lower pressure seat 2, thereby changing the curvature of the lower pressure seat 2, so that the lower pressure seat 2 can abut against the patient's tongue root, thereby supporting the patient's tongue and avoiding damage to the epiglottis cartilage; the laryngoscope is clamped with the clamping block 8 on the oropharyngeal airway 1, and The optical fiber on the laryngoscope passes through one of the operating holes 9 and passes through the lower pressing seat 2, thereby completing the visual acquisition work of the laryngoscope; the elastic frame 21 is provided to complete the clamping and limiting work of the trachea 5, and the mounting protrusion 22 and the mounting groove 23 provided on the elastic frame 21 cooperate to complete the assembly work of multiple elastic frames 21, and assemble them according to their own needs to form a chain-like structure, by connecting the connecting wires to the threading holes 11 on the elastic frame 21 in sequence, after tightening the threading holes 11, the lower pressing seat 2 can be bent so that it can abut against the patient's tongue root;

[0069] When the laryngoscope is used to observe that there is a lot of sputum in the area to be tested or the input gas is too dry, the driving member 64 can drive the adjustment shaft 67 to move. The moving adjustment shaft 67 can squeeze the physiological saline in the mounting seat 61. When the squeezed physiological saline overcomes the elastic force generated by the deformation of the support spring 663, water can be sprayed from the water spray seat 63 and enter the patient's body along with the gas, thereby moistening the gas or diluting the sputum in the patient's throat, thereby improving the operator's observation clarity and expanding the operator's field of view.

[0070] When it is necessary to push and inject the saline solution, the button 641 is pressed. The moving button 641 can drive the driving tube 643 to move, thereby driving the connecting seat 644 to move. The moving connecting seat 644 can change the deformation of the return spring 645 while pushing the adjustment shaft 67 to move. The moving adjustment shaft 67 can complete the injection of the saline solution. After the injection is completed, the elastic force generated by the deformation of the return spring 645 can drive the adjustment shaft 67 to move in the opposite direction. Under the limit of the limit plate 642, the return spring 645 can make the driving tube 643 be in the initial position, thereby ensuring the smooth injection of the saline solution next time.

[0071] When the amount of saline solution injected needs to be adjusted, the driving rod 654 is pushed, causing relative displacement between the driving rod 654 and the gear 655, thereby driving the gear 655 to rotate. The moving gear 655 can drive the control sleeve 672 to rotate, and the rotating control sleeve 672 can drive the delivery tube 651 to rotate. Since the adjusting shaft 67 is provided with a spiral groove, the linear distance between the spiral groove and the injection port 6511 can be adjusted. By changing the linear distance between the two, the injection amount is changed, thereby completing the adjustment of the amount of saline solution injected.

[0072] When the normal saline solution is injected, the normal saline solution can enter the delivery cavity 6512 along the water inlet 62, and then move into the delivery tube 651 through the provided filling port 6511. Then, the adjusting shaft 67 is driven by the driving member 64 to move in the delivery tube 651, thereby squeezing the liquid in the delivery tube 651, so that the liquid can be sprayed out from the water spray seat 63 after overcoming the elastic force generated by the deformation of the support spring 663. As the adjusting shaft 67 continues to move, the filling port 6511 is connected to the second groove 674, and the pressure relief work of the liquid is completed. At this time, even if the adjusting shaft 67 continues to move, the liquid cannot overcome the elastic force generated by the support spring 663. The elastic force generated by the deformation of the spring 663 and the liquid will flow into the delivery chamber 6512 along the first groove 673, the second groove 674 and the third groove 675, so that the excess liquid will not be sprayed out from the water spray seat 63, and it can be recovered to avoid its waste. After completing the above work, at this time, under the push of the reset spring 645, the adjustment shaft 67 moves in the opposite direction, so that a negative pressure is formed between the adjustment shaft 67 and the delivery tube 651, and then when the adjustment shaft 67 is away from the inlet 6511, the physiological saline can be located in the delivery tube 651 under the influence of its own gravity and negative pressure, ensuring the smooth progress of the next physiological saline injection.
