Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and more particularly to a portable laryngeal suction device. Background Technology

[0002] In clinical practice, critically ill patients, postoperative patients, the elderly, and newborns often have difficulty expectorating sputum. Sputum accumulation in the trachea can easily lead to risks such as suffocation and lung infection. Suctioning is a key nursing procedure. Traditional suctioning equipment mainly consists of central negative pressure suction devices and large electric suction devices. These devices are bulky, rely on fixed power sources or central negative pressure sources, and cannot be adapted to scenarios such as in-hospital transport, home care, and outdoor emergency care. Portable tracheal suction devices have been gradually developed, taking into account portability, safety, and ease of use.

[0003] In the prior art, Chinese patent document CN118743793B discloses a deep suction device for sputum removal, aiming to solve the problem of sputum re-entering the patient's throat, thus affecting the suction effect. This invention, through the design of a contact member and a notch, allows the contact member to extend into the patient's mouth. Then, the suction tube, inserted into the patient's mouth, passes through the contact member and the notch and extends into the patient's throat. This action ensures that when the suction tube is subsequently withdrawn, it will not come into contact with the patient's mouth, thus preventing sputum from being scraped and retained on the outer wall of the suction tube in the patient's mouth. Simultaneously, the patient's swallowing action will not re-absorb sputum from the outer wall of the suction tube, thereby reducing the probability of the suction effect being affected.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: portable suction devices are mostly driven manually for easy carrying. The traditional piston push requires both hands to operate at the same time, which is inconvenient. In addition, the suction device has a single function and it is not easy to moisten the throat before suctioning, which increases the patient's discomfort. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing portable suction device has the disadvantages of inconvenience due to the traditional piston pushing operation and lack of humidification function. Therefore, we propose a portable laryngeal suction device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a portable laryngeal suction device, comprising a nebulizer and a suction tube, wherein a nebulizing component is provided on the upper part of the nebulizer, a control panel is provided on the outer surface of the nebulizer, a first conduit is fixedly connected to the end of the nebulizer, a three-way valve is fixedly connected to the end of the first conduit away from the nebulizer, a reciprocating component is provided on the outer surface of the suction tube, a reset component is provided inside the reciprocating component, an adjustment component is provided inside the reset component, and a disassembly component is provided on the lower surface of the nebulizer; The reciprocating assembly includes an air bladder fixedly connected to the tail end of the suction tube, a piston plate slidably connected inside the suction tube, and a corrugated tube fixedly connected to the side of the piston plate near the air bladder. The reset assembly includes a round rod fixedly connected inside the airbag, and the inner wall of the airbag is provided with a ring array of support plates.

[0007] Preferably, the atomizing component includes a water pipe fixedly connected to the upper surface of the atomizing cylinder, a ceramic atomizing plate is provided on the inner wall of the connection between the water pipe and the atomizing cylinder, and a battery is provided inside the atomizing cylinder.

[0008] Preferably, a second conduit is fixedly connected to the end of the three-way valve tube away from the nebulizer, the end of the second conduit away from the three-way valve tube is connected to the suction tube, and a third conduit is provided in the middle of the three-way valve tube.

[0009] Preferably, the end of the corrugated tube away from the piston plate is fixedly connected to the inner wall of the end of the suction tube, and the corrugated tube is hollow inside and communicates with the inside of the air bladder.

[0010] Preferably, the lower part of the suction tube is provided with a receiving tube, and the connection between the receiving tube and the suction tube is located on the side of the piston plate away from the corrugated tube.

[0011] Preferably, a cross shear bar is hinged to the outer surface of the round rod, and the end of the cross shear bar away from the round rod is hinged to the outer surface of the support plate.

[0012] Preferably, springs are provided at the ends of the two shafts of the cross shear bar.

[0013] Preferably, the adjusting assembly includes a bidirectional threaded rod that is movably inserted inside the round rod, a slide block is slidably connected to the outer surface of the bidirectional threaded rod, a push rod is hinged to the outer surface of the slide block, and a baffle is hinged to the end of the push rod away from the slide block.

[0014] Preferably, a knob is fixedly connected to one end of the bidirectional threaded rod extending out of the airbag, and a strip groove is formed on the outer surface of the round rod, with the push rod slidably connected inside the strip groove.

[0015] Preferably, the assembly / disassembly assembly includes a mounting base fixedly connected to the lower surface of the nebulizer, and a mounting plate is provided on the upper surface of the suction tube, the mounting plate being snapped into the interior of the mounting base.

[0016] The technical effects and advantages of this invention are as follows: In this invention, by setting up a nebulizing component and a reciprocating component, the dual effects of suctioning and nebulization can be achieved. The negative pressure generated by the compression and rebound of the airbag is used to suction out the phlegm in the trachea. In addition, by using a ceramic nebulizing pad, nebulization can be achieved before and after suctioning, achieving the effect of moistening or nebulizing the medicine. In this invention, by setting a reset component inside the airbag, the support plate and cross scissor rod are simultaneously compressed after the airbag is pressed, which in turn causes the spring to extend. After the airbag is released, the spring rebounds and pushes the cross scissor rod and support plate to support the airbag, which plays a role in assisting the airbag to rebound and expand, thereby increasing the suction effect. In this invention, by setting an adjustment component, the position of the baffle is adjusted by rotating the bidirectional threaded rod. In this way, the baffle is used to limit the movement and control the compression amplitude of the airbag, thereby achieving the effect of adjusting the suction force. Attached Figure Description

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1 to 6As shown, the present invention provides a technical solution: a portable laryngeal suction device, including a nebulizer 1 and a suction tube 5. The upper part of the nebulizer 1 is provided with a nebulizing component 2, the outer surface of the nebulizer 1 is provided with a control panel 3, the end of the nebulizer 1 is fixedly connected with a first conduit 41, the end of the first conduit 41 away from the nebulizer 1 is fixedly connected with a three-way valve tube 4, the outer surface of the suction tube 5 is provided with a reciprocating component 6, the reciprocating component 6 includes a reset component 7 inside, the reset component 7 is provided with an adjustment component 8 inside, and the lower surface of the nebulizer 1 is provided with a disassembly component 9. The nebulizer assembly 2 includes a water pipe 21 fixedly connected to the upper surface of the nebulizer cylinder 1. A ceramic nebulizer plate 22 is provided on the inner wall of the connection between the water pipe 21 and the nebulizer cylinder 1. A battery 23 is provided inside the nebulizer cylinder 1. A second conduit 42 is fixedly connected to the end of the three-way valve pipe 4 away from the nebulizer cylinder 1. The end of the second conduit 42 away from the three-way valve pipe 4 is connected to the suction tube 5. A third conduit 43 is provided in the middle of the three-way valve pipe 4. The control panel 3 is model EC0051H. The control panel 3 is used to control the operation of the ceramic nebulizer plate 22. The battery 23 is also equipped to power both of them.

[0021] When performing sputum suction on a patient, the third catheter 43 is connected to the patient's larynx. The switch on the three-way valve is turned to close the third catheter 43, connecting the first catheter 41 and the second catheter 42. At this time, the operator sends a start command through the control panel 3. After receiving the signal, the low-power MCU drives the ceramic nebulizer 22 to vibrate at high frequency. The water in the water pipe 21 comes into contact with the vibrating nebulizer and is broken into micron-sized water mist, which is delivered to the larynx through the first catheter 41 to humidify the airway. The water in the water pipe 21 is converted into water mist after contacting the running ceramic nebulizer 22 and sent into the first catheter 41, eventually entering the larynx, which can achieve a humidifying effect. According to the patient's needs, the water in the water pipe 21 can be replaced with medication to nebulize the medication and achieve more functions.

[0022] Reference Figure 1 and Figure 4 As shown, the reciprocating assembly 6 includes an air bladder 61 fixedly connected to the tail end of the suction tube 5. A piston plate 63 is slidably connected inside the suction tube 5. A corrugated tube 62 is fixedly connected to the side of the piston plate 63 near the air bladder 61. The end of the corrugated tube 62 away from the piston plate 63 is fixedly connected to the inner wall of the end of the suction tube 5. The corrugated tube 62 is hollow inside and communicates with the inside of the air bladder 61. A receiving tube 64 is provided at the lower part of the suction tube 5. The connection between the receiving tube 64 and the suction tube 5 is located on the side of the piston plate 63 away from the corrugated tube 62.

[0023] Pressing the airbag 61 compresses it, forcing the gas inside into the bellows 62. The gas fills the bellows 62, causing it to expand and extend, which in turn pushes the piston plate 63 to move within the suction tube 5. When the pressure is reached to the limit, releasing the airbag 61 causes it to rebound and expand, drawing in the gas from the bellows 62. The bellows 62 then contracts, pulling the piston plate 63 back. The suction force at this point draws the sputum from the trachea into the suction tube 5, where it falls into the collection container 64, completing the suction operation. The structure is simple and can be operated with one hand.

[0024] Reference Figure 4 and Figure 5 As shown, the reset assembly 7 includes a round rod 71 fixedly connected inside the airbag 61. Support plates 72 are distributed in a ring array on the inner wall of the airbag 61. A cross shear rod 73 is hinged to the outer surface of the round rod 71. One end of the cross shear rod 73 away from the round rod 71 is hinged to the outer surface of the support plate 72. Springs 74 are provided at the two shaft ends of the cross shear rod 73.

[0025] When the airbag 61 is pressed, the pressure on the airbag 61 compresses the support plate 72 that is attached to the inner wall of the airbag 61, thereby pushing the support plate 72 to move towards the round rod 71 and compress the cross scissor bar 73. The cross scissor bar 73 will change from a state that is close to a rectangle to a state that is close to a straight line, which will pull the spring 74 to extend, thus storing force. After the airbag 61 is released, the spring 74 rebounds and pushes the cross scissor bar 73 to extend, which will push the support plate 72 to open the airbag 61 and restore it, thus assisting the airbag 61 to rebound and expand, increasing the suction effect.

[0026] Reference Figure 5 and Figure 6 As shown, the adjustment assembly 8 includes a bidirectional threaded rod 81 that is movably inserted inside the round rod 71. A slide block 82 is slidably connected to the outer surface of the bidirectional threaded rod 81. A push rod 83 is hinged to the outer surface of the slide block 82. A baffle 84 is hinged to the end of the push rod 83 away from the slide block 82. A knob 85 is fixedly connected to the end of the bidirectional threaded rod 81 that extends out of the airbag 61. A strip groove 86 is opened on the outer surface of the round rod 71. The push rod 83 is slidably connected inside the strip groove 86.

[0027] The rotary knob 85 drives the bidirectional threaded rod 81 to rotate, which in turn drives the slide 82 to move. During the movement of the slide 82, the push rod 83 slides in the strip groove 86 and pushes the baffle 84 to move. The baffle 84 is set in the cross scissor bar 73. When the airbag 61 is pressed, the cross scissor bar 73 retracts and is blocked by the baffle 84. Thus, by adjusting the position of the baffle 84, the pressing amplitude of the airbag 61 can be changed, thereby achieving the effect of adjusting the suction force.

[0028] Reference Figure 2 and Figure 4As shown, the assembly / disassembly component 9 includes a mounting base 91 fixedly connected to the lower surface of the nebulizer 1, and a mounting plate 92 is provided on the upper surface of the suction tube 5. The mounting plate 92 is snapped into the interior of the mounting base 91.

[0029] The mounting plate 92 can be connected by aligning it with the mounting base 91 and snapping it in, making it easy to carry. After suctioning, the suction tube 5 can be removed from the nebulizer tube, and the removed three-way valve tube 4 and suction tube 5 can be easily cleaned.

[0030] Working principle: This device has both suctioning and nebulization functions. The nebulization tube and the suction tube 5 are connected by the disassembly and assembly component 9. The connection can be achieved by aligning the mounting plate 92 with the mounting base 91 and snapping it in, which is convenient for carrying. When performing suctioning on a patient, the third catheter 43 is connected to the patient's larynx. Turning the switch on the three-way valve closes the third catheter 43, connecting the first catheter 41 and the second catheter 42. At this time, the ceramic nebulizer 22 is activated through the control panel 3. The water in the water pipe 21 comes into contact with the running ceramic nebulizer 22 and is converted into water mist, which is sent into the first catheter 41 and finally into the larynx, providing a humidifying effect. According to the patient's needs, the water in the water pipe 21 can be replaced with medication to nebulize the medication and achieve more functions. After nebulization is complete, close the first tubing 41 and open the third tubing 43. Press the airbag 61; the pressure on the airbag 61 will compress the support plate 72 against its inner wall, pushing the support plate 72 towards the round rod 71 and compressing the crossbar 73. The crossbar 73 will change from a near-rectangular state to a near-straight state, thus pulling the spring 74 to extend, achieving a force storage effect. Simultaneously, the compression of the airbag 61 forces the gas inside to enter the bellows 62. The gas filling the bellows 62 causes it to expand and extend, pushing the piston plate 63 to move within the suction tube 5. When the pressure is reached at its limit, release the airbag 61. The spring 74's rebound will push the crossbar 73 to extend, which in turn pushes the support plate 72 to open and return the airbag 61 to its original position. Thus, the expansion of the airbag 61 will... When air is drawn into the bellows 62, the bellows 62 contracts, pulling the piston plate 63 back. At this time, the suction force draws sputum from the trachea into the suction tube 5 and into the receiving tube 64, completing the suction operation. The structure is simple and can be operated with one hand. The adjustment components 8 set inside and outside the round rod 71 can change the compression amplitude of the airbag 61. By turning the knob 85, the bidirectional threaded rod 81 is rotated, which in turn drives the slide 82 to move. During the movement of the slide 82, the push rod 83 slides in the strip groove 86 and pushes the baffle 84 to move. The baffle 84 is set inside the cross scissor bar 73. When the airbag 61 is pressed, the cross scissor bar 73 contracts and is blocked by the baffle 84. Thus, by adjusting the position of the baffle 84, the compression amplitude of the airbag 61 can be changed, thereby achieving the effect of adjusting the suction force. After suctioning is completed, remove the first catheter 41 from the three-way valve tube 4, separate the third catheter 43 from the larynx and connect the first catheter 41 to the larynx. At this time, the nebulization function can be realized again. At the same time, the suction tube 5 is removed from the nebulization tube. The removed three-way valve tube 4 and suction tube 5 can be easily cleaned.

[0031] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
