Detailed Description
As shown in fig. 1-4, a thoracic surgery special drainage device comprises a suction tube 1, one end of the suction tube 1 is connected with a suction head 2, the other end is connected with a connecting tube 3 of a suction apparatus, when in use, the suction tube 1 and the suction head 2 are put into a body cavity, and effusion is sucked out through the suction head 2, the suction tube 1 and the connecting tube 3 in sequence. The suction head 2, the suction tube 1, the connecting tube 3 and the like are made of medical grade materials, wherein medical grade silica gel is preferably used.
The present invention is largely different from the conventional suction device in that, as shown in fig. 2 and 3, the suction head 2 is formed in a hollow cylindrical shape, and one end of the suction head 2 is fixedly connected to the suction tube 1. The side wall of the suction head 2 is provided with a plurality of annular grooves 4, as shown in fig. 3, the number of the grooves 4 is 3, and actually, the grooves can be more and more dense, the groove walls on the two sides of the grooves 4 are provided with a plurality of liquid suction holes 5 communicated with the inside of the suction head 2, and the positions of the liquid suction holes 5 on the two sides of the grooves 4 are opposite.
In the use process of the invention, the accumulated liquid is sucked by the suction head 2, firstly enters the groove 4, then enters the suction head 2 through the liquid suction hole 5 in the groove 4, and finally is discharged from the suction tube 1. The suction tube has the advantages that the traditional situation that suction is directly carried out through the end part of the suction tube 1 is abandoned, the suction force is dispersed into the liquid suction holes 5, the situation that the suction force at the end part of the suction tube 1 is too large and the human tissue is directly adsorbed is prevented, and meanwhile, the tissue can be blocked and supported by the grooves 4, so that the tissue is prevented from extending into the grooves 4, and the suction risk is further reduced; in addition, the liquid suction holes 5 are symmetrically distributed on two sides of the groove 4, and a pulling force is generated on the accumulated liquid in the liquid suction process, so that thick mucus can be torn and separated, the risk of blockage is reduced, and the suction is more stable and smooth, and on the basis, in order to further improve the smoothness of the suction head 2, the edge part of the outer profile surface of the suction head 2 is provided with an arc-shaped chamfer.
In the using process, when the position needing suction is deep, the suction tube 1 is often required to be shaped to a certain degree, so that the suction head 2 can reach the target position directly, therefore, a shaping steel wire 6 is arranged in the suction tube 1, and the shaping steel wire 6 penetrates through a plurality of connecting pieces 7 uniformly distributed on the inner wall of one side of the suction tube 1 and is connected with the suction tube 1. Because of the existence of the shaping steel wire 6, the suction tube 1 can be bent and shaped to a certain extent, and then the bending degree of the suction tube 1 and the angle of the suction head 2 relative to the suction tube 1 are adjusted, so that the use is facilitated.
In order to prevent the effusion from flowing back, as shown in fig. 2, a movable sealing sheet 8 is arranged on the inner wall of the suction head 2 at the liquid suction hole 5, the movable sealing sheet 8 is a rubber sheet, one end of the movable sealing sheet 8 is stuck on the inner wall of the suction head 2 at one side of the liquid suction hole 5, and the other end extends to a position enough to cover the liquid suction hole 5. When the accumulated liquid flows towards the inside of the suction head 2, the movable sealing sheet 8 can be propped open and smoothly enters the suction head 2; otherwise, the movable sealing sheet 8 is pushed to block the liquid sucking hole 5 to prevent backflow.
Besides, because the suction tube 1 and the suction head 2 are parts which need to be inserted into the body cavity of the human body, in order to meet the hospital feeling requirement, the suction tube is a disposable consumable, and is convenient to replace. The opposite ends of the suction tube 1 and the connecting tube 3 are respectively provided with a first connector 9 and a second connector 10, and the first connector 9 and the second connector 10 form quick detachable connection.
As shown in fig. 4, one end of the first connection head 9 is connected to the suction tube 1, a first annular ridge 11 and a second annular ridge 12 are respectively arranged on the other end of the first connection head 9 and the outer peripheral surface of the middle section, the cross sections of the first annular ridge 11 and the second annular ridge 12 are both semicircular, and the outer side wall of the first connection head 9 between the first annular ridge 11 and the second annular ridge 12 is provided with a back-proof tooth 13.
The second connector 10 is in a stepped tubular shape, the small-size section of the second connector 10 is communicated with the connecting pipe 3, and a layer of sealing rubber 14 is arranged on the inner surface of the large-size section of the second connector 10. The inner surface of the sealing rubber 14 at the opening end of the large-size section of the second connector 10 is provided with a third annular rib 15, and the protruding height of the third annular rib 15 is matched with that of the first annular rib 11. Still be the annular and evenly be provided with many elastic strips 16 that extend towards second connector 10 jumbo size section on the ladder face of second connector 10, first connector 9 card is established between the jumbo size section of elastic strip 16 and second connector 10. The outer surface of the overhanging end of the elastic strip 16 is also provided with a fourth annular ridge 17.
When in use, the first connector 9 and the second connector 10 are oppositely inserted, and the first connector 9 props the large-size section of the second connector and the elastic sheet 17 to extend between the two. During the continuous insertion process, the sealing rubber 14 on the inner wall of the large-size section of the second connecting head 10 is pressed by the first annular edge 11 and the second annular edge 12, and good sealing is realized. Meanwhile, after the sealing rubber 14 is pressed to deform, the middle section of the sealing rubber bulges and is contacted with the anti-withdrawal pawl 13, so that the first connector 9 and the second connector 10 are tightly connected, the sealing is good, and the sealing cannot be released. After the use is finished, the first connector 9 and the second connector 10 are respectively held by hands to be pulled forcefully towards the two ends, and can be separated quickly, so that the use is very convenient.
