DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example 1: Reference Figure 1 A medical polymer material oral foreign body aspirator is characterized by comprising: a suction disc mechanism 1, the suction disc mechanism 1 is connected to the side wall of the connecting plate 2, the other side wall of the connecting plate 2 is connected to the end of the suction tube 3 through a hose, the side wall of the hose is equipped with a guide mechanism 4, the guide mechanism 4 is connected to the suction disc mechanism 1, and the other end of the suction tube 3 is connected to the suction device 5.

[0032] The working principle and beneficial effects of the above technical solution are:

[0033] The suction disc mechanism 1 is connected to the side wall of the connecting plate 2, and the other side wall of the connecting plate 2 is connected to the end of the suction tube 3 through a hose. A one-way valve is provided in the end of the hose connected to the connecting plate 2 to prevent the backflow of solids. The side wall of the hose is equipped with a guide mechanism 4, which is connected to the suction disc mechanism 1. The other end of the hose is connected to the end of the suction tube 3. The side wall of the suction tube 3 is engraved with a scale line for identifying the volume of the sucked material. The other end of the suction tube 3 is connected to the suction device 5. By arranging the suction disc mechanism 1 in the device, the end of the suction disc mechanism 1 is connected to the guide mechanism 4, and the suction device 5 provides the suction disc mechanism 1 with a negative pressure for sucking solids. The diameter of the suction disc mechanism 1 can be adjusted by the guide mechanism 4 to meet the needs of patients of different age groups. At the same time, after adjusting the diameter, the parts of the oral cavity that are difficult to clean can be suctioned and cleaned.

[0034] Example 2: Reference Figure 2 and Figure 3 The suction cup mechanism 1 includes: a mounting bar 11, one end of the mounting bar 11 is fixed to the side wall of the connecting plate 2, and the other end of the connecting plate 2 is provided with an arc-shaped through groove, and a rubber disc sleeve 12 is provided on the side wall of the mounting bar 11. The upper and lower top surfaces of the rubber disc sleeve 12 are provided with multiple through holes, and the open end of the rubber disc sleeve 12 is sealed and fitted with the side wall of the connecting plate 2. The other end of the mounting bar 11 passes through the arc-shaped through groove, and a plurality of arc-shaped teeth are provided on the side wall of the mounting bar 11, which engage with the guide mechanism 4. A pair of through grooves are provided on the side wall of the connecting plate 2, and a guide component 13 is provided in the through groove. The guide component 13 slides with the inner wall of the mounting bar 11.

[0035] The working principle and beneficial effects of the above technical solution are:

[0036] The side wall of the mounting bar 11 is provided with a rubber disc sleeve 12, and the side wall of the mounting bar 11 is provided with a plurality of arc-shaped teeth, which are connected to the guide mechanism 4. The guide mechanism 4 adjusts the diameter of the circular ring formed by the mounting bar 11, and the guide component 13 fits the inner wall of the mounting bar 11. The guide component 13 guides the mounting bar 11 and maintains the shape of the mounting bar 11. The rubber disc sleeve 12 can change its diameter synchronously with the change of the diameter of the mounting bar 11. The rubber disc sleeve 12 can be inserted into the patient's oral cavity for suction and can be adjusted accordingly according to the size of the patient's oral cavity. At the same time, after adjusting the diameter, the dead corners in the patient's oral cavity can be cleaned; the open end of the rubber disc sleeve 12 is sealed with the side wall of the connecting plate 2 to prevent solid matter from leaking out due to poor sealing effect when the suction device 5 is started; multiple holes are provided on the upper and lower end surfaces of the rubber disc sleeve 12, which can efficiently suck solid matter in the oral cavity.

[0037] Example 3: Reference Figure 1 、 Figure 4 and Figure 10The guide assembly 13 includes: a column 131, and the two through slots on the side wall of the connecting plate 2 are respectively connected to the columns 131, and a pair of guide arms 133 are respectively rotatably installed on the columns 131. The bottom ends of the pair of guide arms 133 are respectively connected to the ends of the torsion springs 132, and the other ends of the pair of torsion springs 132 are respectively connected to the bottom walls of the through slots, and the arc-shaped side walls of the pair of guide arms 133 are in contact with the inner wall of the mounting bar 11.

[0038] The working principle and beneficial effects of the above technical solution are:

[0039] A guide arm 133 is rotatably mounted on the upright post 131 in the guide assembly 13. The bottom end of the guide arm 133 is connected to the end of a torsion spring 132. The other end of the torsion spring 132 is connected to the bottom wall of the through slot. The guide mechanism 4 adjusts the diameter of the mounting bar 11. When the diameter of the mounting bar 11 becomes larger, the torsion spring 132 releases its elastic force, and the end of the torsion spring 132 drives the guide arm 133 to rotate outward. The guide arm 133 guides the mounting bar 11 and pushes the side wall of the mounting bar 11 outward. When the diameter of the mounting bar 11 becomes smaller, the guide arm 133 is pressed inward by the inward pressure of the mounting bar 11 to move inward, and the guide arm 133 drives the bottom end connected to the upright post 131. The ends of the torsion spring 132 connected thereto rotate in the same direction, and the other end of the torsion spring 132 connected to the bottom wall of the through groove remains stationary. The torsion spring 132 stores energy to prepare for the next release of elastic force, thereby improving the movement efficiency of the mechanism. An arc-shaped side wall with the same shape as the inner wall of the mounting bar 11 is provided on the outside of the guide arm 133, which can efficiently guide the mounting bar 11 when its diameter changes. At the same time, the guide arm 133 can support the mounting bar 11 to prevent the rubber disc sleeve 12 from being deformed due to the deformation of the mounting bar 11 after the device is extended into the oral cavity, thereby improving the rationality of the mechanism and avoiding the decrease in suction efficiency due to deformation of the mechanism.

[0040] Example 4: Reference Figure 2 and Figure 5 The guide mechanism 4 includes: a mounting block 41, which is fixed on the side wall of the hose. The upper and lower ends of the mounting block 41 are respectively connected to mounting plates 42. A pair of connecting columns are rotatably mounted on the mounting plates 42. The ends of the connecting columns are equipped with knobs. The connecting columns are coaxially fixed with the arc gear 43. The arc side wall of the mounting block 41 slides with the inner wall of the mounting bar 11, and the side wall of the arc gear 43 meshes with the arc teeth of the side wall of the mounting bar 11.

[0041] The working principle and beneficial effects of the above technical solution are:

[0042] The mounting block 41 is mounted on the side wall of the hose, and the upper and lower ends of the mounting block 41 are respectively connected to mounting plates 42, which improves the stability of the mechanism; the connecting column is rotatably mounted on a pair of mounting plates 42, and a knob is installed on the top of the connecting column. The connecting column and the arc gear 43 are coaxially fixed. When the diameter needs to be adjusted, the knob is turned, and the rotation of the knob drives the rotation of the connecting column, and the rotation of the connecting column drives the rotation of the arc gear 43. The side wall of the arc gear 43 engages with the arc teeth of the side wall of the mounting bar 11, which improves the transmission effect and can also assist in maintaining the position of the mounting bar 11 to prevent the rubber disc sleeve 12 on the mounting bar 11 from deformation; the arc side wall of the mounting block 41 frictionally cooperates with the inner wall of the mounting bar 11, which improves the efficiency of the movement of the inner wall of the mounting bar 11 along the mounting block 41, facilitates the sensitive adjustment of the position of the end of the mounting bar 11, and then facilitates the adjustment of the diameter of the suction disc mechanism 1, thereby improving the working efficiency of the mechanism.

[0043] Example 5: Reference Figure 1 The suction device 5 includes: a shell 6, a filtering mechanism 7, a driving mechanism 8 and a vibrating mechanism 9. The filtering mechanism 7, the driving mechanism 8 and the vibrating mechanism 9 are arranged in the shell 6. A through hole is opened on the side wall of the shell 6. The inner wall of the through hole is connected to the side wall of the suction pipe 3. The filtering mechanism 7 is connected to the end of the suction pipe 3. The side wall of the filtering mechanism 7 is connected to the first discharge pipe 71. The first discharge pipe 71 is equipped with a one-way valve. The side wall of the suction pipe 3 is connected to the second discharge pipe 31. The second discharge pipe 31 is equipped with a one-way valve. The output end of the driving mechanism 8 is in sliding fit with the filtering mechanism 7, and the output end of the vibrating mechanism 9 is in friction fit with the filtering mechanism 7.

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The housing 6 has a through hole formed in its side wall, the inner wall of which is connected to the side wall of the suction pipe 3. The filter mechanism 7, drive mechanism 8, and vibrator mechanism 9 are disposed within the housing 6, enhancing the structural strength of the device while preventing malfunctions caused by collisions within the internal mechanisms. During suction, the output end of the drive mechanism 8 slides with the filter mechanism 7, which is in communication with the end of the suction pipe 3. The drive mechanism 8 provides the negative pressure required for suction to the suction disc mechanism 1. The suction pipe 3 is connected to the second discharge pipe 31, and the sucked solids are discharged through a one-way valve within the second discharge pipe 31, thereby improving the rationality and discharge efficiency of the device. The filter mechanism 7 is connected to the first discharge pipe 71, and the sucked gas and liquid, after filtration, are discharged through the one-way valve within the first discharge pipe 71, thereby improving discharge efficiency. The output end of the vibrator mechanism 9 frictionally engages with the filter mechanism 7. When some solids are not discharged by the second discharge pipe 31, the vibrator mechanism 9 discharges the remaining solids into the second discharge pipe 31, preventing the mechanism from being clogged by solids and causing damage.

[0046] Example 6: Reference Figure 1and Figure 6 The filtering mechanism 7 includes: a sleeve 72, one end of the sleeve 72 is connected to the end of the suction pipe 3, the side wall of the sleeve 72 is connected to the first discharge pipe 71, a polymer filter tube 73 is coaxially installed in the sleeve 72, the end of the polymer filter tube 73 is connected to the vibration mechanism 9, and the inner wall of the polymer filter tube 73 is slidably matched with the output end of the driving mechanism 8.

[0047] The working principle and beneficial effects of the above technical solution are:

[0048] The output end of the driving mechanism 8 slides in the polymer filter tube 73, providing negative pressure for the suction of the suction disc mechanism 1, while allowing the gas and liquid on the inner wall of the polymer filter tube 73 to enter the first discharge pipe 71. The one-way valve in the first discharge pipe 71 opens, and the gas and liquid are discharged. A small amount of small-diameter solids are left on the inner wall of the polymer filter tube 73. When the driving mechanism 8 performs reverse movement, the one-way valve in the first discharge pipe 71 is reset, and a small amount of small-diameter solids remaining on the inner wall of the polymer filter tube 73 are pushed upward and enter the second discharge pipe 31 through the vibration and transportation of the vibration mechanism 9. The small-diameter solids are discharged, thereby improving the efficiency of solid discharge of the device and avoiding damage to the suction device 5 due to the accumulation of solids.

[0049] Example 7: Reference Figure 7 The driving mechanism 8 includes: a first motor 81, which is installed in the housing 6. The output end of the first motor 81 is connected to an adjusting component 82, which is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is hinged to the end of a piston 83. The side wall of the piston 83 slides with the inner wall of the polymer filter tube 73 through a sealing strip.

[0050] The working principle and beneficial effects of the above technical solution are:

[0051] The first motor 81 is installed in the shell 6, and the output end of the first motor 81 is connected to the adjustment component 82. The adjustment component 82 is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is hinged to the end of the piston 83. By adjusting the position of the adjustment component 82, the angle formed between the end of the connecting rod and the linear motion direction of the piston 83 can be changed. When the angle between the connecting rod and the linear motion of the piston 83 becomes larger, the stroke of the piston 83 is lengthened, which is convenient for increasing the negative pressure of the mechanism and sucking a large amount of solid matter in the oral cavity. The angle between the connecting rod and the linear motion of the piston 83 becomes smaller, and the stroke of the piston 83 becomes shorter, thereby reducing the negative pressure of the mechanism, reducing the energy consumed by the equipment, and increasing the service life of the equipment.

[0052] Example 8: Reference Figure 8The adjusting assembly 82 includes: a mounting plate 84, the side wall of which is coaxially connected to the output end of the first motor 81, and a plurality of circular grooves are provided in a radial linear array on the mounting plate 84, one of which is plugged with an adjusting bolt 85, and a pair of nuts are respectively installed on the threads at both ends of the adjusting bolt 85, and a positioning ring is connected to the adjusting bolt 85, and the side wall of the positioning ring is in contact with the side wall of the mounting plate 84, and the end of the connecting rod is rotatably mounted on the adjusting bolt 85, and the other side wall of the positioning ring and the inner wall of one of the nuts are frictionally fitted with the two side walls of the connecting rod respectively.

[0053] The working principle and beneficial effects of the above technical solution are:

[0054] A mounting ring is coaxially connected to the adjusting bolt 85, and the mounting ring is located in the middle of the adjusting bolt 85. Threads are provided at both ends of the adjusting bolt 85, and nuts are threadedly connected to the threads. The mounting plate 84 has multiple through holes in the linear array direction. The mounting ring cooperates with one of the nuts and is clamped on one of the through holes of the mounting plate 84. The mounting ring and the other nut clamp the end of the connecting rod. The adjusting bolt 85 body guides the connecting rod. When it is necessary to increase the reciprocating distance of the piston 83, the adjusting bolt 85 is moved from the through hole of the mounting plate 84 that is closer to the center of the disk body to the through hole that is farther away from the center. Otherwise, the adjusting bolt 85 is moved to the through hole that is closer to the center of the disk body of the mounting plate 84, which reduces the complexity of the mechanism and facilitates maintenance of the device.

[0055] Example 9: Reference Figure 1 and Figure 9 The vibration mechanism 9 includes: a primary filter screen 91, which is installed in the suction pipe 3, one side of the primary filter screen 91 is in contact with the end of the polymer filter tube 73, a second motor 92 is installed in the shell 6, and the output end of the second motor 92 passes through the inner wall of the suction pipe 3, and a cam 94 is installed at the output end of the second motor 92. The side wall of the cam 94 is frictionally engaged with the other side of the primary filter screen 91, and an auger 95 is rotatably installed on the inner wall of the suction pipe 3. One end of the auger 95 cooperates with the second discharge pipe 31 to discharge solids. A pulley 93 is installed on the output shaft of the second motor 92, and the pulley 93 is connected to the driven wheel at the other end of the auger 95 through a belt.

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] The side wall of the primary filter screen 91 is installed in the suction pipe 3, and one side of the primary filter screen 91 is in contact with the end of the polymer filter tube 73. One side of the primary filter screen 91 blocks the large-diameter solids sucked into the device to prevent the driving mechanism 8 from being damaged due to the large diameter of the solids. The second motor 92 rotates to drive the cam 94 to rotate. The end of the cam 94 rubs against the side wall of the primary filter screen 91 and vibrates, so that the large-diameter solids are separated from the primary filter screen 91. The pulley 93 connected to the output end of the second motor 92 rotates, and the auger 95 is driven by the belt to rotate, and the auger The auger 95 shaft guides the vibrated solids into the second discharge pipe 31, where the one-way valve opens and the solids are discharged. Under the pressure of the output end of the driving mechanism 8, the other side of the primary filter screen 91 guides the solids with smaller diameters entering the polymer filter tube 73 in the opposite direction, and after passing through the primary filter screen 91, they re-enter the suction pipe 3. The solids with smaller diameters are transported to the second discharge pipe 31 through the rotation of the auger 95, where the one-way valve opens and the solids are discharged, thereby improving the rationality and automation of the equipment and reducing the number of cleaning and maintenance times of the device.

[0059] The working principle and beneficial effects of the above technical solution are:

[0060] When the driving mechanism 8 makes a reverse motion, the one-way valve in the connecting pipe 102 is reset to prevent the solids left in the rubber disc sleeve 12 from entering the connecting pipe 102 and causing the device to be blocked.
