Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an indicator component for endotracheal intubation and an endotracheal tube. Background Technology

[0002] Endotracheal intubation involves inserting a endotracheal tube through the mouth or nose into the trachea to ensure adequate ventilation for the patient during surgery. Endotracheal intubation has been used clinically for a long time and is an indispensable auxiliary medical device for treating and improving respiratory failure, contributing significantly to the rescue of patients with respiratory failure.

[0003] Chinese patent CN203017529U discloses an endotracheal tube, including a tube body, an inflatable cuff, an inflation tube, and an indicator balloon.

[0004] During use, excessive air pressure inside the cuff can damage the patient's trachea, while insufficient air pressure can easily cause the intubation tube to loosen. Currently, the technology can only estimate the size of the cuff inside the trachea based on the size of the indicator balloon, making it difficult for patients and medical staff to intuitively understand whether the air pressure inside the cuff is appropriate. This needs to be improved. Summary of the Invention

[0005] To facilitate understanding whether the air pressure of the airbag is appropriate, this application provides an indicator component for endotracheal intubation and an endotracheal tube.

[0006] On the one hand, the endotracheal intubation indicator assembly provided in this application adopts the following technical solution:

[0007] An indicator assembly for endotracheal intubation includes:

[0008] A connecting tube, one end of which is provided with a tube head for connecting to an interface of an indicator airbag, and the other end of which is an inflation end;

[0009] An indicator tube, one end of which is connected to the connecting tube, and an indicator for indicating air pressure is provided inside the indicator tube;

[0010] The mounting part is connected to the tube head and is used to lock the tube head to the interface of the indicator airbag.

[0011] By adopting the above technical solution, when in use, the tube head is connected to the interface of the indicator airbag, and the tube head is locked at the interface by the installation part to prevent loosening or falling off; because the indicator tube is connected to the connecting tube and the indicator airbag, during use, patients and medical staff can understand in real time whether the airbag pressure is appropriate according to the markings inside the indicator tube.

[0012] Optionally, the marking element includes a piston and an elastic element. The indicating tube is made of a transparent material. The piston is slidably disposed inside the indicating tube along the axial direction. The elastic element is disposed inside the indicating tube to drive the piston to move toward the connecting tube. Multiple scale lines are provided on the indicating tube along the axial direction.

[0013] By adopting the above technical solution, during the inflation process, the gas will push the piston to move away from the connecting tube. The position of the piston on the corresponding scale line can be used to intuitively understand the air pressure and determine when the air pressure inside the airbag is appropriate.

[0014] Optionally, the end of the indicator tube away from the connecting tube may be detachably provided with an end cap.

[0015] Optionally, a seal is provided between the end cap and the indicator tube.

[0016] Optionally, the mounting part includes a retaining strip and a retaining ring. One end of the retaining strip is fixedly connected to the pipe head. Multiple retaining strips are arranged along the circumference of the pipe head. A deformation groove is provided between two adjacent retaining strips. The thickness of the retaining strip gradually increases from the end closer to the pipe head to the end farther away from the pipe head. The retaining ring is threaded onto the retaining strip.

[0017] By adopting the above technical solution, when using the device, after the tube head is fitted onto the interface of the indicator airbag, rotate the retaining ring. The retaining ring moves along the end away from the connecting tube, so that the retaining strip gradually tightens the airbag interface, ensuring a sealed connection of the connecting tube and preventing the connecting tube from loosening or falling off during use.

[0018] Optionally, the inner wall of the tube head is inclined, and the inner diameter of the tube head gradually decreases from the end near the opening of the tube head to the end away from the opening.

[0019] Optionally, a valve is provided on the connecting pipe, and the valve is located on the connecting pipe between the indicator pipe and the inflation end.

[0020] By adopting the above technical solution, a certain amount of gas will be released when the inflation device is removed, resulting in a decrease in air pressure inside the airbag. After inflation is complete, the valve should be closed first, and then the inflation device should be removed, effectively preventing gas leakage and ensuring stable air pressure in the airbag.

[0021] On the other hand, the endotracheal intubation tube provided in this application adopts the following technical solution:

[0022] An endotracheal tube includes the aforementioned endotracheal tube indicator component.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When using, connect the tube head to the interface of the indicator airbag and lock the tube head in place at the interface using the mounting part to prevent loosening or falling off; because the indicator tube is connected to the connecting tube and the indicator airbag, patients and medical staff can understand whether the airbag pressure is appropriate in real time according to the indicator inside the indicator tube.

[0025] 2. When in use, after the tube head is fitted onto the interface of the indicator airbag, rotate the retaining ring. The retaining ring moves along the end away from the connecting tube, so that the retaining strip gradually tightens the airbag interface, ensuring a sealed connection of the connecting tube and preventing the connecting tube from loosening or falling off during use.

[0026] 3. When the inflation device is removed, a certain amount of gas will be released, causing a decrease in air pressure inside the airbag. After inflation is complete, close the valve first, and then remove the inflation device to effectively prevent gas leakage and ensure stable air pressure in the airbag. Attached Figure Description

[0034] This application discloses an indicator component for endotracheal intubation.

[0035] Reference Figure 1 and Figure 2 An indicator assembly for endotracheal intubation includes a connecting tube 1, an indicator tube 2, and a mounting part 3. One end of the connecting tube 1 is provided with a tube head 11 for connecting to an interface of an indicator airbag 6, and the other end of the connecting tube 1 is an inflation end 12. The connecting tube 1 can be a straight tube with openings at both ends or a curved tube.

[0036] Reference Figure 2 The inner wall of the tube head 11 is inclined, and the inner diameter of the tube head 11 gradually decreases from the end near the opening to the end away from the opening. The interface between the tube head 11 and the indicator airbag 6 is an interference fit to prevent gas leakage. The inner wall of the tube head 11 is provided with an abutment platform 111. During installation, the tube head 11 is fitted onto the interface of the indicator airbag 6 so that the abutment platform 111 is tightly abutted against the interface. This indicates that the tube head 11 and the interface are tightly connected and leak-proof.

[0037] Optionally, a valve 13 is provided on the connecting pipe 1. The valve 13 can be a ball valve, and it is located on the connecting pipe 1 between the indicator pipe 2 and the inflation end 12. Because a certain amount of gas will be released when the inflation device is disconnected, causing a decrease in the air pressure inside the airbag, valve 13 should be closed before disconnecting the inflation device after inflation is complete. This effectively prevents gas leakage and ensures stable air pressure in the airbag.

[0038] Reference Figure 2 One end of the indicator tube 2 is connected to the connecting tube 1. The indicator tube 2 and the connecting tube 1 form a three-way pipe. The indicator tube 2 is made of transparent material. In this embodiment, the indicator tube 2 is made of glass or transparent plastic.

[0039] Reference Figure 2 The indicator tube 2 is equipped with an indicator 4 for indicating air pressure. The indicator 4 includes a piston 41 and an elastic element 42. The piston 41 is slidably disposed in the indicator tube 2 along the axial direction. The surface of the piston 41 is coated with red or other colored pigment. The elastic element 42 is disposed in the indicator tube 2 to drive the piston 41 to move towards the connecting tube 1. The elastic element 42 is configured as a spring.

[0040] Optionally, the indicator tube 2 has multiple scale lines 21 along its axial direction and includes safety range markings. A green marking segment is painted on the indicator tube 2. When the piston 41 is within the green marking segment, it indicates that the air pressure is appropriate and within a safe range, making it easy for medical personnel to check. During inflation, the gas pushes the piston 41 away from the connecting tube 1. The position of the piston 41 on the corresponding scale line 21 provides a direct indication of the air pressure, allowing for the determination of whether the air pressure inside the airbag is appropriate.

[0041] Optionally, an end cap 5 can be detachably provided at the end of the indicator tube 2 away from the connecting tube 1. One end of the spring abuts against the end cap 5, and the other end abuts against the piston 41. The inner wall of the end cap 5 is provided with internal threads, and the end cap 5 is threadedly connected to the indicator tube 2.

[0042] To prevent gas from leaking out of the end cap 5, a sealing element is provided between the end cap 5 and the indicator tube 2. The sealing element is a sealing ring 51. In this embodiment, the sealing ring 51 is a rubber ring. One end of the sealing ring 51 abuts against the inner wall of the end cap 5, and the other end abuts against the end of the indicator tube 2.

[0043] Optional, refer to Figure 2The mounting part 3 is connected to the tube head 11 and is used to lock the tube head 11 to the interface of the indicator airbag 6. The mounting part 3 includes a retaining strip 31 and a retaining ring 32. The retaining strip 31 is made of plastic and has a certain deformation capacity. One end of the retaining strip 31 is fixedly connected to the tube head 11. Multiple retaining strips 31 are arranged along the circumference of the tube head 11, and a deformation groove 33 is provided between adjacent retaining strips 31. The thickness of the retaining strip 31 gradually increases from the end closer to the tube head 11 to the end farther away from the tube head 11. The outer wall of the retaining strip 31 has a threaded groove, and the retaining ring 32 is threadedly fitted onto the retaining strip 31.

[0044] When in use, after the tube head 11 is fitted onto the interface of the indicator airbag 6, rotate the retaining ring 32. The retaining ring 32 moves along the end away from the connecting tube 1, so that the retaining strip 31 gradually clamps the airbag interface, ensuring a sealed connection of the connecting tube 1 and preventing the connecting tube 1 from loosening or falling off during use.

[0045] The implementation principle of this application embodiment is as follows: When in use, the tube head 11 is connected to the interface of the indicator airbag 6, and the tube head 11 is locked at the interface by the mounting part 3 to prevent loosening or falling off; since the indicator tube 2 is connected to the connecting tube 1 and the indicator airbag 6, during use, patients and medical staff can understand in real time whether the airbag pressure is appropriate according to the indicator 4 inside the indicator tube 2.

[0046] This application also discloses an endotracheal intubation method.

[0047] Reference Figure 1 An endotracheal tube includes an endotracheal tube indicator assembly and an indicator cuff 6.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
