    Device for easily and simply coupling to the free end of a small tube (7) mounted on a transfusion needle an apparatus of the type used for coupling a syringe to a drug holding bottle. The device comprises a hollow shaped body (1) coupled to the small tube (7). The hollow body (1) is closed by a plug (5) and a collar (2) shaped like the mouth of a conventional drug bottle projects from the body (1): the collar (2) axially extends and a continuous annular recess (3) is formed therein having such a profile and arrangement to allow for the teeth (11) projecting from the resilient lugs (10) of the apparatus thereto the device is to be coupled to be inserted and locked therein.

    专利说明:

    The invention relates to medical equipment, in particular to devices for introducing liquids, is intended to connect a syringe with a small tube and is an improvement of the invention of Patent No. 5 to patent No. 1308184,
    The aim of the invention is to increase the reliability and ease of connection with the tube.
    Figure 1 shows the device, axo-10; figure 2 is the same, cross section.
    The device comprises a transition unit made in the form of a housing 1 with two cylindrical parts 2 and 3, open from 15 end faces of the housing 1 and provided with blind recesses 4 and 5, respectively. Inside the recesses 4 and 5, protrusions 6 and 7 are made along the longitudinal axis of the housing 1 with through axial channels 8 and 9. which 20 are connected to one another. The first cylindrical part 2 from the front side of the housing 1 is made with the possibility of connection with a small elastic tube 10, the other end of which can be connected with an injection needle (not shown). On the protrusion 7 of the second part 3 from the front side of the casing, an elastic stopper 11, overlapping the channel 9, is made, for example, made of rubber or other similar material 30.
    The plug 11 is securely held on the protrusion 7 by means of a hard disk 12, which is rigidly fixed to the housing 1. An annular recess 13 is formed on the 35 outer surface of the second cylindrical part 3. The device also includes a housing 14, which is made in the form of a cylindrical wall 15, socket 16, petals 17 with teeth 18, plugs 19 and hollow needles 20. The teeth 18 have the ability to interact with the annular recess 13.
    The device operates as follows.
    In the nest 16, the housing 1 is placed with its second cylindrical part 3 so that its ring-shaped recess 13 includes the teeth 18 of the petals 17, which are firmly held in this position by the wall 15, while the plugs 11 and 19 are tightly pressed against each other. On the protrusion 6 puts on the tube 10 connected to the injection needle. The body 14 can be connected to a syringe (not shown), and the needle 20 can pierce the plugs 11 and 19, while the liquid from the syringe can flow through the tube 10 into the injection needle.
    Thus, the proposed device provides reliable connection of a small tube with a syringe.
