In this way, through the flow rate adjustment mechanism, the user can adjust the flow rate according to the patient's coughing ability and comfort, which avoids the problem of stress coughing and asthma caused by excessive flow rate, and improves the safety and effectiveness of the sputum coughing aid.

[0007] Preferably, the flow rate adjustment mechanism comprises a first joint screw-connected to the air inlet end of the hand-held air bag, a second joint screw-connected to the air outlet end of the tee pipe, a first valve hole and a second valve hole respectively formed in the first joint and the second joint and aligned with each other, a fixed shaft fixedly connected to the center of the end of the first joint close to the second joint, and an arc-shaped valve flap rotatably installed outside the fixed shaft and located between the first valve hole and the second valve hole for changing the size of the valve hole by rotating, wherein the first joint and the second joint are fixedly installed.

[0008] Preferably, the fixed shaft has at least two plugs near one end of the second joint, and the second joint has corresponding sockets near one end of the first joint.

[0009] Preferably, the tracheal insertion assembly comprises an extension tube screwed with the air inlet end of the T-tube, a mask sleeved with the air outlet end of the extension tube and fixedly connected with the extension tube for closing the opening, and a ball plug sleeved with the extension tube near the air inlet end and fixedly connected with the extension tube for occluding the trachea.

[0010] Preferably, the arc-shaped valve flap has a lever on the side.

[0011] Preferably, the second joint has a scale on the side corresponding to the lever for identifying the flow.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a cough assist device for lung cancer patients, such as... Figures 1-3 As shown, the lung cancer patient expectoration aid includes a collection container 1 for collecting sputum, a three-way tube 2 with its side end screwed to the opening end of the collection container 1, a tracheal insertion assembly 3 connected to the air inlet end of the three-way tube 2 for insertion into the oral cavity and trachea, and a hand-held airbag 5 connected to the air outlet end of the three-way tube 2 via a flow regulating mechanism 4. The hand-held airbag 5 has an exhaust valve 6 at the end away from the flow regulating mechanism 4 that only allows the gas inside the hand-held airbag 5 to be discharged in one direction.

[0025] When using the expectorant, first insert the tracheal insertion component 3 into the patient's mouth and trachea; then, the user holds the hand-held airbag 5 and squeezes it, the exhaust valve 6 allows the gas inside the airbag to be discharged in one direction, creating negative pressure, thereby generating suction to aspirate sputum from the trachea; through the flow adjustment mechanism 4, the user can adjust the airflow rate according to the patient's expectoration ability and comfort; then, through the tracheal insertion component 3, the sputum is drawn from the patient's trachea to help the patient cough up sputum; during the expectoration process, the sputum is drawn into the tracheal insertion component 3 and flows into the collection tank 1 through the three-way tube 2; after the hand-held airbag 5 is reset, it is ready for the next squeeze.

[0026] Specifically, the flow regulating mechanism 4 includes a first joint 41 screwed with the air inlet end of the hand-held air bag 5, a second joint 42 screwed with the air outlet end of the three-way pipe 2, a first valve hole 411 and a second valve hole 421 respectively formed on the first joint 41 and the second joint 42 and aligned with each other, a fixed shaft 412 fixedly connected at the center of the end of the first joint 41 close to the second joint 42, and an arc-shaped valve disc 43 rotatably installed outside the fixed shaft 412 and between the first valve hole 411 and the second valve hole 421 for changing the size of the valve hole by rotation, wherein the first joint 41 and the second joint 42 are fixedly installed, wherein the end of the fixed shaft 412 close to the second joint 42 has at least two plugs 4121, and the end of the second joint 42 close to the first joint 41 has plug holes 422 corresponding to the plugs 4121; when the arc-shaped valve disc 43 rotates, it changes the size of the overlapping part of the first valve hole 411 and the second valve hole 421, thereby regulating the flow rate of the air flow; the fixed shaft 412 provides a stable rotation center for the arc-shaped valve disc 43, and the rotation of the arc-shaped valve disc 43 realizes the regulation of the flow rate of the air flow; the screwing of the two ends of the three-way pipe 2 and the cooperation of the plugs 4121 and the plug holes 422 realize the detachability, facilitating maintenance and cleaning.

[0027] Specifically, the tracheal insertion assembly 3 includes an extension pipe 31 screwed with the air inlet end of the three-way pipe 2, a mouth cover 32 sleeved on the air outlet end of the extension pipe 31 and fixedly connected with the extension pipe 31 for closing the mouth part, and a ball plug 311 sleeved on the extension pipe 31 close to the air inlet end and fixedly connected with the extension pipe 31 for occluding the trachea; the design of the mouth cover 32 and the ball plug 311 improves the use efficiency of the air flow and reduces leakage, and the screwing design of the extension pipe 31 and the three-way pipe 2 makes the tracheal insertion assembly 3 easy to install and detach, facilitating cleaning and disinfection.

[0028] Further, the arc-shaped valve disc 43 has a lever 431 on the side surface, and the second joint 42 has a scale 423 on the side surface corresponding to the lever 431 for identifying the flow; the user can adjust the flow rate of the air flow by rotating the lever 431 to drive the rotation of the arc-shaped valve disc 43, and the scale 423 provides an intuitive reference for the user to understand the current air flow rate setting.

[0029] It should be noted that the air outlet end of the three-way pipe 2 has a plurality of air holes; to prevent the sputum from being directly sucked into the hand-held air bag 5 due to excessive suction.

[0030] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change within the technical scope disclosed in the present application according to the technical solution and concept of the present application, which should be covered within the protection scope of the present application.
