Description

Technical Field

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

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

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

[0009] One end of the airbag close to the ventilator interface is the sputum collection end, one end of the sputum suction tube is the external end, and the other end is the sputum suction end, and one or more suction holes are provided on the sputum suction end; when the sputum suction tube is wrapped around the cannula body, the sputum suction end is located at the sputum collection end of the airbag.

[0010] The sputum suction tube is made of flexible material and has a spiral structure.

[0011] The cross section of the sputum suction tube is flat.

[0012] The end surface of the sputum suction end of the sputum suction tube is an inclined surface.

[0013] The second airway is arranged in the cannula body between the ventilator interface and the air bag.

[0014] The second air channel is connected to a charging and discharging air pipe, one end of the charging and discharging air pipe is connected to the second air channel, and the other end is connected to a one-way valve.

[0015] The endotracheal tube structure also includes an introduction device, which includes an introduction tube. A spiral groove adapted to the sputum suction tube is provided inside the introduction tube, and a pushing component for driving the sputum suction tube to move along the spiral groove is provided on the introduction tube.

[0016] The pushing assembly comprises a notch formed on the side wall of the introduction tube, and the notch connects the inside and the outside of the introduction tube.

[0017] The pushing assembly also includes a toggle block, which is arranged at the notch and contacts the sputum suction tube arranged in the introduction tube.

[0018] An auxiliary block is provided at one end of the sputum suction tube of the introduction tube, the angle θ between the auxiliary block and the introduction tube is greater than 90° and less than 180°, and the end of the auxiliary block in contact with the cannula body is arranged as an inclined surface.

[0019] After adopting the above scheme, the present invention adds a sputum suction tube to suck out the sputum accumulated on the air bag. First, it reduces the situation where the sputum accumulates too much and too long, causing a large number of bacteria to multiply, effectively reducing the patient's risk of respiratory infection. Once again, it effectively prevents the sputum from splashing and falling off when the cannula body is pulled out, ensuring the safety of pulling out the cannula body, greatly reducing the infection risk of medical staff and the risk of blocking the patient's own respiratory tract after the sputum falls off. Moreover, the present invention arranges the sputum suction tube and the cannula body in a detachable matching manner, and the sputum suction tube is only wrapped around the cannula body when needed, which greatly reduces the discomfort caused to the patient by the setting of the sputum suction tube.

[0020] In addition, in order to facilitate medical staff to wrap the suction tube around the cannula body, the present invention also adds an introduction device. When the suction tube is not in use, it is in the introduction device. When the suction tube is needed, it only needs to operate the introduction device and directly wrap the suction tube around the cannula body, which makes the operation of medical staff easier.

[0034] like Figure 1-7As shown, the present invention discloses a tracheal intubation structure capable of clearing sputum, which comprises an intubation body 10 and a sputum suction tube 30 detachably wound around the intubation body 10. The intubation body 10 is provided with an air bag 20 outside; the intubation body 10 is formed with a first airway 11 and a second airway 12 isolated from each other, the first airway 11 penetrates the intubation body 10 in the length direction of the intubation body 10 and is isolated from the air bag 20, and the second airway 12 is connected to the air bag 20. One end of the air bag 20 close to the ventilator interface 13 is a sputum collection end 21, one end of the sputum suction tube 30 is an external connection end 31, and the other end is a sputum suction end 32, and the sputum suction end 32 is provided with one or more suction holes 321; when the sputum suction tube 30 is wound around the intubation body 10, the sputum suction end 32 is located at the sputum collection end 21 of the air bag 20.

[0035] 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 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 sputum suction end 32 of the sputum suction tube 30 is stuck on the cannula body 10, and then the sputum suction tube 30 is rotated, and the sputum suction tube 30 is gradually wound around the cannula body 10, and moved toward the airbag 20 until the sputum suction end 32 of the sputum suction tube 30 contacts the sputum collection 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 collected at the sputum collection end 21 of the airbag is sucked out by negative pressure. By increasing the number of suction holes 321 of the suction end 32 of the suction tube 30 or slightly rotating the direction of the suction tube 30, all the sputum can be further sucked out. After the sputum is cleared, the suction tube 30 only needs to be rotated in the opposite direction while connected to the negative pressure to be pulled out; when the endotracheal tube needs to be pulled out, the suction tube 30 and the cannula body 10 can be taken out in one go. Since the sputum has been cleared, when the cannula body 10 is taken out, there will be no sputum splashing or falling off, which ensures the safe removal of the cannula body 10 and reduces the risk of infection for medical staff and patients. In addition, the suction tube 30 of the present invention is only used when there is too much sputum adhering to the air bag or when the cannula body 10 is to be pulled out, and will not increase the discomfort of the patient.

[0036] In order to better wind the sputum suction tube 30 around the cannula body 10 , the sputum suction tube 30 is made of a flexible material and has a spiral structure.

[0037] like Figure 3A and Figure 3BAs shown, in order to further reduce the discomfort of the patient, the cross section of the sputum suction tube 30 is flat. In this way, when the sputum suction tube 30 is wound around the cannula body 10, the space it occupies is relatively small, and it can also be well attached to the surface of the cannula body 10, thereby reducing the discomfort caused to the patient by using the sputum suction tube 30.

[0038] The endotracheal tube is generally connected to a ventilator when in use, so one end of the tube body 10 is a ventilator interface 13 , and the other end is a ventilator port 14 ; the second airway 12 is disposed in the tube body 10 between the ventilator interface 13 and the air bag 20 .

[0039] In order to ensure that the airbag 20 does not leak when the endotracheal tube is in use, the second airway 12 is connected to an inflation and deflation tube 15 , one end of which is connected to the second airway 12 , and the other end of which is connected to a one-way valve 16 .

[0040] like Figure 4-Figure 7 As shown, on the basis of the above, in order to facilitate the medical staff to wind the sputum suction tube 30 around the cannula body 10, the tracheal cannula structure also includes an introduction device 40, the introduction device 40 includes an introduction tube 41, the introduction tube 41 is provided with a spiral groove adapted to the sputum suction tube 30, and the introduction tube 41 is provided with a pushing component for driving the sputum suction tube 30 to move along the spiral groove. When the sputum suction tube 30 is not in use, it is packaged together with the introduction tube 41, and the sputum suction tube 30 is arranged in the spiral groove of the introduction tube 41. When the sputum suction tube 30 needs to be used, the medical staff rotates the sputum suction tube 30 through the pushing component, so that the sputum suction tube 30 can move along the spiral groove, come out of the introduction tube 41, and be wound around the cannula body 10.

[0041] In this embodiment, the push assembly includes a notch 42 formed on the side wall of the introduction tube 41, and the notch 42 connects the inside and outside of the introduction tube 41. The medical staff can directly rotate the sputum suction tube 30 with their fingers through the notch 42 to move the sputum suction tube 30.

[0042] In order to ensure that the operation of the medical staff is more convenient, the pushing assembly further includes a toggle block 43, which is arranged at the notch 42 and contacts the sputum suction tube 30 arranged in the introduction tube 41. In this way, the medical staff can rotate the toggle block 43, and the rotation of the toggle block 43 further drives the sputum suction tube 30 to move.

[0043] In order to make the sputum suction tube 30 well inserted into the cannula body 10 after coming out of the introduction tube 41, and to be wound along the cannula body 10, an auxiliary block 44 is provided at one end of the introduction tube 41 where the sputum suction tube 30 is led out, and the angle θ between the auxiliary block 44 and the introduction tube 41 is greater than 90° and less than 180°, and the end of the auxiliary block 44 in contact with the cannula body 10 is arranged as an inclined surface. The end surface of the sputum suction end 32 of the sputum suction tube 30 is an inclined surface.

[0044] 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 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.

[0045] 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.

[0046] 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.
