Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a tracheal intubation structure capable of clearing accumulated sputum. Background Art

[0002] Endotracheal intubation technology is widely used in emergency departments, various ICUs, anesthesia departments, various wards, and various emergency scenes outside the hospital. This technology can provide the best conditions for ventilation, oxygen supply, respiratory suction, etc.

[0003] The endotracheal tube generally includes an intubation body and an air bag arranged on the intubation body. After the air bag is inflated, it is fixed on the patient's trachea or left / right bronchus to prevent the intubation body from loosening. However, as the contact time between the air bag and the patient's trachea increases, sputum will slowly accumulate on the surface of the air bag. Bacteria in the patient's respiratory tract will gather and multiply in large quantities here, causing respiratory infections in patients. Again, when the patient's lung function recovers and reaches the index for removing the endotracheal tube, the medical staff will remove the endotracheal tube. At this time, it is very likely that the sputum adhering to the air bag will splash into the respiratory tract of the medical staff, causing infection of the medical staff, especially for highly infectious diseases such as new coronary pneumonia. The patient's sputum splashes into the air and on the medical staff, which poses a huge threat to the health of the medical staff. At the same time, the sputum adhering to the air bag is also likely to fall off in the trachea before the patient's trachea is removed, causing blockage of part or all of the bronchi or bronchioles of the patient, resulting in weakening or loss of the patient's pulmonary ventilation function.

[0004] Therefore, how to effectively remove the sputum adhering to the endotracheal tube is crucial for both medical staff and patients. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide an endotracheal tube capable of clearing accumulated sputum.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A tracheal intubation structure capable of clearing accumulated sputum, comprising an intubation body and a sputum suction tube detachably embracing the intubation body;

[0008] One end of the cannula body is a ventilator interface, and the other end is a ventilator; an air bag is arranged outside the cannula body, and the end of the air bag close to the ventilator interface is a sputum collection end; a first airway and a second airway isolated from each other are formed in the cannula body, the first airway penetrates the cannula body in the length direction of the cannula body and is isolated from the air bag, and the second airway is connected to the air bag;

[0033] The present invention discloses a tracheal intubation structure capable of clearing accumulated sputum, which comprises an intubation body 10 and a sputum suction tube 30 detachably embracing the intubation body 10 .

[0034] Among them, one end of the cannula body 10 is a ventilator interface 13, and the other end is a ventilator 14; the cannula body 10 is provided with an air bag 20, and the end of the air bag 20 close to the ventilator interface 13 is a sputum collection end 21. The cannula body 10 is formed with a first airway 11 and a second airway 12 that are isolated from each other. The first airway 11 penetrates the cannula body 10 in the length direction of the cannula body 10 and is isolated from the air bag 20, and the second airway 12 is connected to the air bag 20.

[0035] The sputum suction tube 30 includes a sputum suction tube body 31 and an elastic holding portion 32 connected to the sputum suction tube body 31, and the holding portion is used to hold the intubation tube body 10. A cavity is formed in the sputum suction tube body 31, one end of the sputum suction tube 30 is an external end 311, and the other end is a sputum suction end 312, and one or more suction holes 313 are provided on the sputum suction end 312, and the suction holes 313 are connected to the cavity. When the sputum suction tube 30 is wound around the intubation tube body 10, the sputum suction end 312 of the sputum suction tube body 31 is located at the sputum collection end 21 of the air bag 20.

[0036] In the present invention, the cannula body 10 and the sputum suction tube 30 are packaged separately. When it is necessary to ventilate and supply oxygen to the patient, only the cannula body 10 needs to be used. Its use is no different from the original endotracheal cannula, and the difficulty of use will not be increased. When the sputum on the surface of the airbag 20 increases and needs to be removed, or the endotracheal cannula needs to be replaced after long-term use, or the endotracheal cannula needs to be taken out after use, it is only necessary to take out the sputum suction tube 30, and then the elastic holding part 32 of the sputum suction tube 30 is held on the cannula body 10, and then the sputum suction tube 30 is pushed, and the sputum suction tube 30 is gradually moved toward the airbag 20 until the sputum suction end 312 of the sputum suction tube 30 contacts the sputum gathering end 21 of the airbag 20. At this time, one end of the sputum suction tube 30 is connected to the negative pressure suction device, and the sputum gathered at the sputum gathering end 21 of the airbag 20 is sucked out by negative pressure. By increasing the number of suction holes 314 of the sputum suction tube 30 or slightly rotating the direction of the sputum suction tube 30, all the sputum can be further sucked out. After the sputum is removed, the sputum suction tube 30 only needs to be slowly pulled out while connected to the negative pressure state; when the endotracheal tube needs to be pulled out, the sputum suction tube 30 can be taken out together with the tube body 10. Since the sputum has been removed, when the tube body 10 is removed, the sputum will not splash or fall off, ensuring the safe removal of the tube body 10, reducing the risk of infection for medical staff and patients. In addition, the sputum suction tube 30 of the present invention is only used when there is too much sputum adhering to the air bag 20 or when the tube body 10 needs to be pulled out, which will not increase the discomfort of the patient.

[0037] The number of elastic holding parts 32 is generally set to multiple, and can be set on one side or both sides of the suction tube body 31. In this embodiment, the elastic holding part 32 is only provided on one side of the suction tube body 31, and there is a spacing between each elastic holding part 32. When the number of elastic holding parts 32 is set to be large, the spacing will be relatively small, and when the number of elastic holding parts is relatively small, the spacing will be relatively large. In actual application, the number of elastic holding parts 32 is set to be smaller, but the reduction in the number cannot affect the holding degree between the suction tube 30 and the cannula body 10. Of course, the elastic holding part can also be provided on both sides of the suction tube body 31. The elastic holding part provided on both sides can improve the holding degree between the suction tube 30 and the cannula body 10, but it may increase the difficulty of the suction tube 30 fitting on the cannula body 10.

[0038] In order to improve the degree of clasping between the sputum suction tube 30 and the cannula body 10, the cross section of the sputum suction tube body 31 is arc-shaped, and its arc-shaped concave surface fits with the cannula body 10. With this arrangement, when the sputum suction tube 30 is held on the cannula body 10, the sputum suction tube body 31 can fit well with the cannula body 10, so that the sputum suction end 312 of the cannula body 10 can better contact the sputum at the sputum collection end 21 of the air bag 20, so that the collected sputum can be effectively sucked out as completely as possible, effectively reducing the infection risk of patients and medical staff.

[0039] The second airway 12 is disposed in the cannula body 10 between the ventilator interface 13 and the airbag 20. The second airway 12 is connected to an air charging and discharging tube 15, one end of which is connected to the second airway 12, and the other end is connected to a one-way valve 16. When the airbag 20 is inflated using a syringe or other equipment, the gas enters the airbag 20 after passing through the air charging and discharging tube 15 and the second airway 12. When the inflation is completed, the one-way valve 16 can prevent the gas in the airbag 20 from leaking out.

[0040] When the suction tube 30 is in use, the elastic holding part 32 can be unfolded by the medical staff by hand, and then clamped on the cannula body 10. However, such operation will be troublesome. Therefore, the present invention also adds an introduction device 40, which is specifically used to introduce the suction tube 30 into the cannula body 10 to reduce the difficulty of operation for medical staff. The introduction device 40 includes an introduction tube 41, and a space for placing the suction tube 30 in the unfolded holding part state is formed in the introduction tube 41; the introduction tube 41 is provided with a pushing component for driving the suction tube 30 to move along the spiral groove, and a claw for holding the cannula body 10. In this embodiment, the claw is arranged outside the introduction tube 41 and close to the outlet of the introduction tube 41. The pushing component includes a notch 43, and the notch 43 is formed on the side wall of the introduction tube 41, and the notch 43 connects the inside and outside of the introduction tube 41.

[0041] When the sputum suction tube 30 is not in use, it is packaged together with the introduction tube 41, and the elastic holding part 32 of the sputum suction tube 30 is in an expanded state. When the sputum suction tube 30 is needed, the medical staff first clamps the claw 42 on the introduction tube 41 on the cannula body 10, and then moves the elastic holding part 32 of the sputum suction tube 30 through the notch 43, so that the sputum suction tube 30 comes out from the outlet of the introduction tube 41. When the elastic holding part 32 comes out of the introduction tube 41, it returns to a curled state due to the absence of external force, thereby holding the cannula body 10. Continue to push the sputum suction tube 30 so that its sputum suction end 312 contacts the sputum collection end 21 of the air bag 20. In this embodiment, the sputum suction tube 30 is installed in the introduction tube 41. When the sputum suction end 312 of the sputum suction tube 30 contacts the sputum collection end 21 of the air bag 20, the part of the sputum suction tube 30 in the introduction tube 41 can be pulled out, and then the negative pressure drainage device on the machine can be used.

[0042] In addition to the above-mentioned embodiments, the sputum suction tube 30 and the introduction tube 41 can also be installed separately. In this case, the size of the introduction tube 41 will be relatively small. Only an introduction block 44 will be provided at the inlet of the introduction tube 41, and the width of the introduction block 44 will gradually increase from the inlet to the outlet of the introduction tube 41. The main function of the introduction block 44 is to expand the elastic holding portion 32 of the sputum suction tube 30. If this embodiment is adopted, when the medical staff uses the sputum suction tube 30, they need to send the sputum suction tube 30 into the introduction tube 41. Under the action of the introduction block 44, the sputum suction tube 30 enters the introduction tube 41 in an expanded state. Continue to push the sputum suction tube 30, and the sputum suction tube 30 will come out from the outlet of the introduction tube 41, and then hold the cannula body 10. In this embodiment, there is no need to set a pushing component.

[0043] In summary, the key to the present invention is that, by adding a sputum suction tube 30, the sputum collected on the air bag 20 is sucked out, which effectively prevents the sputum from splashing or falling off when the cannula body 10 is pulled out, ensures the safety of pulling out the cannula body 10, and greatly reduces the risk of infection for medical staff and patients. Moreover, the present invention sets the sputum suction tube 30 and the cannula body 10 in a detachable matching manner, and the sputum suction tube 30 is only wound around the cannula body 10 when there is too much sputum adhering to the air bag 20 or the cannula body 10 needs to be pulled out, which greatly reduces the discomfort caused to the patient by the setting of the sputum suction tube 30.

[0044] In addition, in order to facilitate medical staff to wrap the suction tube 30 around the cannula body 10, the present invention further adds an introduction device 40. When the suction tube 30 is not in use, it is in the introduction device 40. When the suction tube 30 is needed, it only needs to operate the introduction device 40 and directly wrap the suction tube 30 around the cannula body 10, which makes the operation of medical staff easier.

[0045] The above description is merely an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
