Abstract
The invention discloses a closed washing and drainage apparatus for osteomyelitis treatment, wherein the apparatus comprises porous foam, a T joint which is arranged in the middle of the porous foam, two drainage tubes and two washing tubes which are connected to two opposite ports of the T joint, and an outer joint which is connected to the other port of the T joint; the T joint comprises an outer tee and an inner tee which are integrally molded; the outer tee and the inner tee are integrally connected in the middle; two opposite ports of the inner tee are connected to the two washing tubes; the two opposite ports of the outer tee are connected to the two drainage tubes; the outer joint includes an outer tube joint and an inner tube joint which are coaxially integrally connected; the inner end of the inner tube joint abuts against the inner tee in a sealed mode, and the inner end of the outer tube joint is in threaded connection to the outer wall of the outer tee; and a biological semitransparent thin film is pressed and sealed when the tee joint is connected to the outer joint, so as to avoid a circumstance that air leakage at the locations of the drainage tubes on the biological semitransparent thin film easily occurs; therefore, a treatment effect is guaranteed.
Description
Technical field
The invention belongs to medical instruments field, the closed irrigation and drainage device used when being specifically related to the operation of a kind of osteomyelitis.
Background technology
When closing irrigation and drainage, VSD froth foam is clogged in medullary cavity, (in foam, is connected with drainage tube and syringe pipe), wound surface N/D person directly sew up, and wound surface has soft tissue defects, and person surface separately covers 1 piece of VSD temporarily closed wound surface again, the whole wound surface of biological semi-permeable membrane sealed; Then go up drip tube and isotonic saline solution bottle and VSD negative pressure suction device to connect, and carry out continual rinsing attraction.The closed irrigation and drainage device of current use, when using biological semi-permeable thin film to carry out wound surface sealing, easily causes disappointing in drainage tube position, and troublesome poeration and air-tightness are difficult to ensure, result of use is undesirable, has increased the weight of the working strength of medical personnel.
Summary of the invention
Technical problem to be solved by this invention is: the deficiency existed for prior art, provides a kind of simple and practical, biological semi-permeable diaphragm seal can be made easily to put in place, do not produce the closed irrigation and drainage device of gas leakage.
For solving the problems of the technologies described above, be achieved by the following technical solutions: a kind of closed irrigation and drainage device for osteomyelitis treatment, include porous foam, be arranged on the three way cock in porous foam centre position, be connected to drainage tube and the syringe pipe of three way cock two opposite end mouth, and be connected to the coupling of three way cock another port; Described three way cock includes integrated outer threeway and interior threeway, outer threeway and interior threeway are connected as a single entity at medium position, the relative port of interior threeway two is connected with two described syringe pipes, and the relative port of outer threeway two is connected with the drainage tube described in two; Described drainage tube sidewall evenly offers conduction hole, and described syringe pipe passes from the conduction hole of drainage tube medium position, and extends to the end position of porous foam; Described coupling has outer tube joint and the inner pipe joint of coaxial one connection, and the outer end of outer tube joint is connected with the outer wall one of inner pipe joint, and the inner of inner pipe joint seals with interior threeway and abuts, and the inner of outer tube joint and the outer wall of outer threeway are threaded connection; The side of outer tube joint is connected with negative pressure joint, and the outer end of inner pipe joint is syringe pipe joint.
Preferably: the port outer wall that described outer threeway is connected with outer tube joint forms external screw thread, the inner inwall of outer tube joint forms female thread, and outer threeway is positioned at externally threaded bottom position forms a sealing and abut circle, outer tube joint is inner abut with sealing enclose between be provided with sealing ring.
Preferably: two relative ports of described interior threeway extend out to outside two relative ports of two outer threeways.
Compared with prior art, the invention has the beneficial effects as follows: by using the three way cock with interior threeway, outer Three way structure, coordinate the coupling with outer tube joint, inner pipe joint integrative-structure, facilitate the connection of the two, and biological semi-permeable film compression can be sealed when the two connects, avoid the situation that biological semi-permeable thin film easily leaks air in drainage tube position, ensure that therapeutic effect, alleviate the work load of medical personnel.

Detailed description of the invention
According to
fig. 1extremely
fig. 4shown in, a kind of closed irrigation and drainage device for osteomyelitis treatment described in the present embodiment, include porous foam 1, be arranged on the three way cock 4 in porous foam centre position, be connected to drainage tube and the syringe pipe 3 of three way cock two opposite end mouth, and be connected to the coupling 5 of three way cock another port; Described three way cock includes integrated outer threeway 42 and interior threeway 41, outer threeway and interior threeway are connected as a single entity at medium position, the relative port of interior threeway two is connected with two described syringe pipes, and the relative port of outer threeway two is connected with the drainage tube described in two; Described drainage tube sidewall evenly offers conduction hole 21, and described syringe pipe passes from the conduction hole of drainage tube medium position, and extends to the end position of porous foam; Described coupling has outer tube joint 51 and the inner pipe joint 52 of coaxial one connection, the outer end of outer tube joint is connected with the outer wall one of inner pipe joint, the inner of inner pipe joint seals with interior threeway and abuts, and the inner of outer tube joint and the outer wall of outer threeway are threaded connection; The side of outer tube joint is connected with negative pressure joint 512, and the outer end of inner pipe joint is syringe pipe joint.Described the inner is that one end that coupling is connected with three way cock.
The port outer wall that described outer threeway is connected with outer tube joint forms external screw thread 421, the inner inwall of outer tube joint forms female thread 511, and outer threeway is positioned at externally threaded bottom position forms a sealing and abut circle 422, outer tube joint is inner abut with sealing enclose between be provided with sealing ring.
