Example 1
As shown in fig. 1 to 4, a saliva collector capable of preventing splashing comprises a funnel 1, a collection tube 2 and a rubber ring 3, wherein the top end of the collection tube 2 is connected with the output end of the funnel 1, an internal thread is arranged on the inner surface of the output end of the funnel 1, a corresponding external thread is arranged on the outer portion of the top end of the collection tube 2, the rubber ring 3 is arranged at the bottom of the external thread of the collection tube 2, the front surface of the top end of the funnel 1 is a mouth-attaching surface 11, the mouth-attaching surface 11 is a downward-bent arc-shaped edge, an upward-protruding vent tube 4 is arranged on the back surface of the funnel 1, the mouth-attaching surface 11 is designed according to the shape of a human lip, when the mouth-attaching device is used, the arc-shaped edge is close to the lip, so that when spitting saliva into the funnel 1, the spitting out of the funnel 1 to cause environmental pollution is avoided, the rubber, after the collecting pipe 2 is in threaded connection with the funnel 1, the phenomenon that saliva flows out from a gap formed by the connection of the collecting pipe 2 and the funnel 1 due to quality defects of the collecting pipe 2 or the funnel 1 to cause environmental pollution is prevented, the ventilating pipe 4 is arranged on the back surface of the funnel 1 and is used for keeping balance of air pressure inside and outside the collector, in order to prevent the saliva from splashing, the collector generally clings a mouth to the top of the funnel, so that the collector is in a relatively sealed state during collection, the air pressure inside and outside the collector can be unbalanced along with the breathing of the collector, the ventilating pipe 4 is arranged to balance the air pressure inside and outside, the viscous saliva can be ensured to smoothly enter the collecting pipe 2 from the funnel 1, and the ventilating pipe 4 is upwards protruded, so that the blockage can be avoided, the saliva can be further effectively prevented from splashing outside from the funnel 1 to cause environmental pollution, the outer surface of the collecting tube 2 is provided with scale marks 5, the scale marks 5 are used for conveniently observing the content of saliva in the collecting tube 2, the collecting tube further comprises an upper flow-limiting cover 6 and a lower flow-limiting cover 7, the upper flow-limiting cover 6 is arranged at the upper part of an internal thread at the output end of the funnel 1, an upper through hole 8 is arranged on the upper flow-limiting cover, the lower flow-limiting cover 7 is arranged at the top of the collecting tube 2 and flush with the tube opening, three lower through holes 9 are arranged on the lower flow-limiting cover, the number of the upper through holes 8 is 1, the lower flow-limiting holes are arranged at the central point of the lower flow-limiting cover 7, the upper through hole 8 and the lower through holes 9 are arranged in a staggered manner, the upper flow-limiting cover 6 can be in close contact with or separated from the lower flow-limiting cover 7 by rotating the collecting tube 2, when the upper flow-limiting cover 6 is separated from, when the upper flow limiting cover 6 is in close contact with the lower flow limiting cover 7, saliva cannot flow into the collection tube 2 from the funnel 1, saliva in the collection tube 2 cannot flow into the funnel 1 from the collection tube 2, the upper and lower flow limiting covers 7 and the upper and lower through holes 9 are arranged, so that residual saliva always exists on the funnel 1 when collection work is finished, when the collection tube 2 is taken out from the output end of the funnel 1, residual saliva on the inner wall of the funnel 1 can fall onto the ground from the inner wall of the funnel 1 to cause environmental pollution, in order to avoid the situation, the flow limiting covers are arranged to follow the through holes, when collection is carried out, the upper flow limiting cover 6 and the lower flow limiting cover 7 are in an incomplete contact state by rotating the collection tube 2, so that the saliva can flow into the collection tube 2 from the funnel 1, after collection is finished, the collection tube 2 is rotated, the collection tube 2 continues to move upwards until the lower flow limiting cover 7 is in complete contact with the upper flow limiting cover 6, because the lower through holes 9 and the upper through holes 8 are distributed in a staggered manner, saliva in the collecting pipe 2 can be well stored in the collecting pipe 2 and cannot flow out, at the moment, the whole collecting pipe 2 is inverted, residual saliva on the inner wall of the funnel 1 flows into a specified collecting position from the pipe orifice of the funnel 1 to prevent pollution, after the residual saliva on the inner wall of the funnel 1 is discharged, the funnel 1 is inverted back to be restored to a normal position, then the collecting pipe 2 is rotated to be taken out from the output end of the funnel 1, the height of the internal thread and the external thread is 1.8-2.0 cm, the thread height is too high, when the saliva is collected normally, the distance between the top of the collecting pipe 2 and the upper limit flow cover 6 is too close, the flow rate of the saliva is easy to slow, the saliva is accumulated, the through holes are blocked, and the thread height is too low, so that the connection between the collecting pipe 2 and the funnel 1 is not, the bottom of the collecting tube 2 is provided with a soft pressing part 10, the pressing part 10 is in a circular truncated cone shape, the pressing part 10 is arranged for detecting the air tightness inside the collecting tube 2 when the top of the collecting tube 2 is in close contact with the upper limiting flow cover 6, if the pressing part 10 of the collecting tube 2 is pressed, the pressing part 10 deforms, it is proved that the inside of the collecting tube 2 is not completely sealed, the top of the collecting tube 2 is not in close contact with the upper limiting flow cover 6, the collecting tube 2 needs to be continuously rotated to enable the collecting tube 2 to move upwards to be in close contact with the top and the upper limiting flow cover 6, when inversion is prevented, saliva flows out of the collecting tube 2, if the pressing part 10 at the bottom of the collecting tube 2 is pressed, and the pressing part 10 does not deform, it is proved that the air tightness inside of the collecting tube 2 is good, and the. The use principle of the embodiment is as follows: the mouth is hugged closely at the funnel top by the person of gathering, spit out a certain amount of saliva in funnel 1, it is intraductal to pour into collection pipe 2 through funnel 1 with the liquid that preserves in the liquid pipe, rotatory collection pipe 2, make collection pipe 2 rebound to lower current limiting cover 7 and upper current limiting cover 6 in close contact with, then press the splenium 10 of pressing of collection pipe 2 bottom, detect the inside gas tightness of collection pipe 2, after the detection finishes, invert the collector, make remaining saliva on funnel 1 inner wall pour into appointed collection department, then invert the collector and resume normal position to, it takes out again to reverse rotation collection pipe 2, cover the lid and screw up the back and invert the mixing several times with the sample tube, accomplish collection work. The beneficial effect of this embodiment is: 1. when the collecting tube is taken out, the residual saliva on the funnel can not fall to the ground.
