The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the inner pipe 1, the pipe body 11, the transition screening part 12, the thin extension part 13, the bevel 131, the thin slit groove 132, the limiting piece 14, the outer pipe 2 and the screening structure 21.
Examples
The embodiment is basically shown in figures 1-6, and the sleeved saliva suction tube shown in figure 1 comprises an inner tube 1 and an outer tube 2, wherein the lower end of the inner tube 1 is detachably and fixedly connected with a negative pressure suction device arranged outside, the inner tube 1 is in sliding fit with the outer tube 2, no gap exists between the outer wall of the inner tube 1 and the inner wall of the outer tube 2, or the interference is less than 0.02mm, and the inner tube 1 and the outer tube 2 are all flexible tubes which are generally made of medical grade plastics, rubber or silica gel, and have certain elasticity, so that the inner tube 1 and the outer tube 2 can slide relatively, but cannot be easily separated, and the saliva suction tube is prevented from falling off from the inner tube 1 and the outer tube 2 in the using process; as shown in fig. 3, the inner tube 1 comprises a tube body 11, a transition screening part 12 and a thin extension part 13 which are connected in sequence, wherein a limiting piece 14 is arranged at the position, close to the lower end, of the tube body 11; the upper end of the outer tube 2 is provided with a screening structure 21, as shown in fig. 4, the upper end of the thin extension part 13 is provided with an inclined opening 131 which is an outer arc surface, and the back surface of the inclined opening 131 is provided with a thin slit 132.
As shown in fig. 2, the transition screening part 12 is spaced from the screening holes of the screening structure 21, and the outer wall of the transition screening part 12 and the inner wall of the screening structure 21 can be completely attached (i.e. the radian dimensions of the two are the same), as shown in fig. 5, when the outer tube 2 is slid to the position of the limit piece 14 of the inner tube 1, the thin extension part 13 of the inner tube 1 is completely extended, at the moment, the non-perforated part of the screening structure 21 of the outer tube 2 blocks the screening holes of the transition screening part 12 of the inner tube 1, so that the inner tube 1 forms an airway passage, and the saliva suction tube at the moment is equivalent to a saliva suction tube with smaller caliber and stronger suction force, and can be used for sucking deeper blood or other liquid in the incision or the tooth socket of the oral cavity operation area; as shown in fig. 6, after the thin extension portion 13 of the inner tube 1 is completely immersed in the outer tube 2, due to the existence of the transition screening portion 12 of the inner tube 1, the airway passage of the outer tube 2 is smooth, and the transition screening portion 12 can also play a role in blocking sundries, at this time, the saliva suction tube is equivalent to a saliva suction tube with a larger caliber and weaker suction force, and can be used for sucking saliva or other liquids in the oral cavity; when the thin extension part 13 of the inner tube 1 partially extends out of the outer tube 2, the saliva suction tube at this time is equivalent to a saliva suction tube with smaller caliber and weaker suction force, and can be used for other scenes such as shallower incision of an intraoral operation or smaller bleeding amount.
The plastic tube further comprises at least one shaping wire which is arranged in the tube wall of the inner tube 1 or the outer tube 2, and the shaping wire is made of metal wires or alloy wires, is easy to bend and has a shaping effect.
The specific implementation process is as follows:
When it is required to suck blood or other liquid deeper in the incision of the oral surgical area or in the alveolus, as shown in fig. 5, the outer tube 2 is slid to the position of the limiting piece 14 of the inner tube 1, so that the thin extension portion 13 of the inner tube 1 is fully extended, which is equivalent to a saliva suction tube with smaller caliber and stronger suction (which is equivalent to the existing strong suction tube commonly known in the art);
