Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a portable nursing sputum suction device. Background Art

[0002] A portable suction device is a small, lightweight device that is easy to carry and use. It is usually composed of three parts: a negative pressure pump, a collection container and a suction tube. When in use, the suction tube is gently inserted into the patient's throat, and then the negative pressure pump is started to effectively suck the sputum and collect it into the container. In order to improve the suction effect, the existing technology recommends combining specific operating techniques: that is, after starting the negative pressure pump, the operator needs to rotate the suction tube while pulling it moderately to widen the suction coverage area and prevent the side wall opening of the suction tube from contacting the same area of ​​the throat for a long time, thereby reducing possible harm to the patient.

[0003] However, in combination with actual work, we found that the use of existing ordinary portable sputum suction devices can easily cause discomfort and is inconvenient to operate. For example, the portable handheld sputum suction device disclosed in the prior art with publication number CN221154883U requires the operator to have certain experience and skills when using such a sputum suction device, because the rotation and pulling actions may cause friction on the throat during operation, causing discomfort to the patient.

[0038] During specific use, after the operator inserts the suction tube 11 into the patient's throat, he only needs to start the main body 1 and the drive motor 59 at the same time, and use the drive component 5 to drive the inner tube 3 to rotate and move relative to the suction tube 11, so that the suction hole 4 is connected with the multiple through holes 2 on the suction tube 11 in turn, thereby automatically completing a full range of suction operations without the need for manual operation by the operator.

[0045] Example 2: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: Example 2 is another specific implementation of the driving member 54 in Example 1.

[0046] In this embodiment, the driving member 54 includes a U-shaped frame 67 fixedly connected to the main body 1, and the U-shaped frame 67 is rotatably connected to the shaft 3 68, and the shaft 3 68 is fixedly connected to the cylinder 2 69, and one end of the wire rope 53 is fixedly connected to the shaft 4 71, and one end of the shaft 4 71 slides through the U-shaped frame 67 and is rotatably connected to the slide plate 72 through the bearing, and the slide plate 72 is fixedly connected to the cylindrical protrusion 61, and the cylinder 2 69 is provided with a guide groove member 74, and one end of the cylindrical protrusion 61 is located in the guide groove member 74, and the U-shaped frame 67 is fixedly connected to the driving motor 2 75, and the output shaft of the driving motor 2 75 is fixed to the shaft 3 68, and the driving motor 2 75 is started to drive the cylinder 2 69 to rotate, and the guide groove member 74 is used to intermittently drive the cylindrical protrusion 61 to move;

[0047] A transmission member 76 is provided between shaft three 68 and shaft four 71 . When cylinder two 69 rotates, the transmission member 76 is used to drive shaft three 68 to rotate so as to drive the wire rope 53 to rotate. A guide rod 77 is fixedly connected to the U-shaped frame 67 , and the guide rod 77 slides through the slide plate 72 .

[0048] The transmission member 76 includes a toothed disc 1 78 fixedly connected to the shaft 3 68, a toothed disc 2 79 meshing with the toothed disc 1 78 is rotatably connected to the U-shaped frame 67, and one end of the shaft 4 71 passes through the toothed disc 2 79, a slide groove 2 81 is provided on the shaft 4 71, a slide protrusion 2 82 is fixedly connected to the toothed disc 2 79, and the slide protrusion 2 82 is located in the slide groove 2 81 to guide and limit the movement of the shaft 3 68.

[0049] Sprocket one 78 is designed with a diameter larger than that of gear two 79. Specifically, the radius of gear one 78 is twice that of gear two 79, that is, when gear one 78 rotates half a circle, gear two 79 will drive shaft three 68 to rotate one circle, which is manifested in that the inner tube 3 performs a 360-degree suction operation, thereby fully covering the through holes 2 on the suction tube 11, thereby increasing the coverage range during suction. At the same time, on this basis, the arc groove 83 is semi-circular. Specifically, when cylinder two 69 rotates half a circle, the cylindrical protrusion 61 also slides from the arc groove 83 into the spiral groove two 84. Subsequently, cylinder two 69 rotates half a circle again, and the cylindrical protrusion 61 slides from the spiral groove two 84 into the arc groove 83, and this is repeated in sequence.

[0050] The guide groove member 74 includes a plurality of arc grooves 83 evenly and equidistantly provided on the cylindrical body 69. One end of the cylindrical protrusion 61 is located in the arc groove 83 and is slidably connected to the inner wall thereof. Specifically, when the cylindrical protrusion 61 slides in the arc groove 83, the inner tube 3 rotates relative to the sputum suction tube 11 on the inner tube 3. A plurality of spiral grooves 84 are evenly and equidistantly provided on the cylindrical body 69, and two adjacent arc grooves 83 are connected by a spiral groove 84. When the cylindrical protrusion 61 slides along the spiral groove 84, the inner tube 3 slides relative to the sputum suction tube 11 on the inner tube 3.

[0051] Specifically, when the drive motor 2 75 is started, the shaft 3 68 is driven to rotate, thereby driving the cylinder 2 69 to rotate. At this time, the cylindrical convex 61 first slides in the arc groove 83, and at the same time, the rotation of the shaft 3 68 drives the gear plate 1 78 to rotate, to drive the gear plate 2 79 to rotate, and then drives the shaft 4 71 to rotate, thereby driving the wire rope 53 and the inner tube 3 to rotate at the same time. When the cylinder 2 69 continues to rotate, the cylindrical convex 61 will slide along the spiral groove 2 84 into the next arc groove 83, and then drive the shaft 4 71 and the wire rope 53 to move, to drive the inner tube 3 to move, and repeat in sequence, so that the inner tube 3 rotates one circle, moves a certain distance, and then rotates one circle again, and repeats in sequence to increase the suction range.

[0052] Example 3: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: Example 3 is another specific implementation of the guide groove member 74 in Example 2.

[0053] In this embodiment, the guide groove member 74 includes two groups of semi-circular arc grooves 85 that are evenly and equidistantly opened on both sides of the second cylinder 69, and the two groups of semi-circular arc grooves 85 are staggered along the second cylinder 69. A plurality of vertical slide grooves 86 are opened on the second cylinder 69, and two adjacent semi-circular arc grooves 85 in the two groups of semi-circular arc grooves 85 are connected head to tail by a vertical slide groove 86. Specifically, when the cylindrical protrusion 61 slides along the semi-circular arc groove 85, it is manifested on the inner tube 3 that the inner tube 3 rotates relative to the sputum suction tube 11, and when the cylindrical protrusion 61 slides along the vertical slide groove 86, it is manifested on the inner tube 3 that the inner tube 3 slides relative to the sputum suction tube 11;

[0054] The guide rod 77 is designed with a thread, but the guide rod 77 is still slidably connected to the slide plate 72. One end of the guide rod 77 passes through the U-shaped frame 67 and is rotatably connected to the U-shaped frame 67, and one end of the guide rod 77 is fixedly connected to a synchronous pulley 1 87. One end of the shaft 3 68 is fixedly connected to a synchronous pulley 2 88. The synchronous pulley 1 87 and the synchronous pulley 2 88 are connected by a synchronous belt. When the drive motor 2 75 is started, the shaft 3 68 is driven to rotate, and then the guide rod 77 is driven to rotate through the synchronous pulley 2 88 and the synchronous pulley 1 87. One end of the slide plate 72 is slidably connected to a guide rod 89. Both ends of the guide rod 89 are fixedly connected to displacement plates 91, and the guide rod 77 passes through two displacement plates 91 and is threadedly connected to them. Elastic belts 92 are fixedly connected between the two displacement plates 91 and the slide plate 72. When the guide rod 77 rotates, the two displacement plates 91 are driven to slide relative to the slide plate 72, and at the same time, the elastic belt 92 on one side of the slide plate 72 is stretched to provide it with self-restoring elastic force.

[0055] Specifically, when the drive motor 2 75 is started, the shaft 3 68 is driven to rotate, thereby driving the cylinder 2 69 to rotate. At this time, the cylindrical convex 61 first slides in the semicircular arc groove 85, and at the same time, the shaft 3 68 rotates to drive the gear plate 1 78 to rotate, thereby driving the gear plate 2 79 to rotate, and then driving the shaft 4 71 to rotate, thereby driving the wire rope 53 and the inner tube 3 to rotate at the same time. At this time, the shaft 3 68 rotates to drive the synchronous pulley 2 88 to rotate to drive the synchronous pulley 1 87 to rotate, thereby driving the guide rod 77 to rotate synchronously, and then driving the two displacement plates 91 to move relative to the slide plate 72, and then When the elastic band 92 on one side of the slide plate 72 is stretched and the cylinder 69 continues to rotate, the cylindrical protrusion 61 will be embedded in the vertical slide groove 86. At this time, the cylindrical protrusion 61 is out of the obstruction, and the elastic band 92 is reset to drive the slide plate 72 and the cylindrical protrusion 61 to slide along the vertical slide groove 86 and enter the next semicircular arc groove 85, thereby driving the shaft 4 71 and the wire rope 53 to move, and driving the inner tube 3 to move, and repeating in sequence, so that the inner tube 3 rotates one circle, moves a certain distance, and then rotates another circle, and repeats in sequence to increase the suction range. This design can make the movement of the inner tube 3 faster and improve work efficiency.
