Definitions

  • the invention relates to a device for the introduction of medical devices, in particular a medical closing device, into tissue openings, in particular into an artery of an individual, with a funnel-shaped insertion part made of a solid material and with an elastic hose part adjoining the insertion part in question, the is able to surround the respectively inserted medical device in a contact area running towards its distal end.
  • Devices of the type mentioned above are used in medical treatment practice in order to establish access routes for medical devices in the tissue and in particular in the arteries of individuals, which have to be passed through tissue openings or with which one has to work in tissue openings. After the medical devices have been introduced, the devices in question are then released from the devices in question, for example by tearing open and wiping them off, with which they then have fulfilled their task.
  • the invention is therefore based on the object of showing a way in which a device of the type mentioned can be ensured in a relatively simple manner that practically no space remains between the elastic tube part of such a device and a medical device inserted into it , if the cross-sectional shape of the medical device in question clearly differs from the cross-section of the elastic hose part in question and is in particular an oval shape.
  • the object outlined above is achieved according to the invention in a device of the type mentioned at the outset in that the hose part and, if appropriate, the funnel-shaped insertion part are surrounded by an enclosing device in which at least below a transition region between the funnel-shaped insertion part and the proximal end of the hose part in the abovementioned contact region a separately activatable pressure element is contained, by the activation of which the tube part in the relevant contact area can be at least largely positively brought into contact with the medical device inserted in each case.
  • the invention has the advantage that it can be ensured in a relatively simple constructive manner that between the inside of the elastic hose part and During use, the outside of a medical device inserted into this tube part has practically no interfering space through which a liquid, in particular blood, can pass. Because the aforementioned tube part can be at least largely positively connected to the medical device inserted in the abovementioned abutment area, medical devices with external shapes can be used which are significantly different from the internal shape of the elastic tube part, which usually has a round cross section , By means of the at least one provided activatable pressure element, it can thus be achieved that the elastic tube part in question practically rests against the outside of the respective medical device.
  • the present invention thus provides a device which, as it were, fulfills a lock function for the medical device used in each case.
  • a particularly simple and expedient structure for the use of medical devices with a rotationally symmetrical cross section, in particular with an oval cross section, results from the fact that two diametrically opposed pressure elements are provided.
  • the respective pressure element is expediently formed by an inflatable air cushion. This results in the advantage of a device that is particularly easy to set up.
  • the respective printing element prefferably be formed by a mechanical printing device. In this way, stronger compressive forces can be achieved than with one or more inflatable air cushions.
  • the respective pressure element expediently has on its inside a shape adapted to at least part of the outer shape of a medical device. This gives the advantage of a particularly effective device in terms of minimizing a passage existing between the outside of a medical device and the inside of the tube part mentioned.
  • the encircling device preferably surrounds a plastic body, in which the respective pressure element is embedded and which is able to rest on the elastic hose part and optionally also on the funnel-shaped insertion part. This has the advantage of a particularly efficiently usable containment device.
  • a device that can be used particularly safely and reliably results from the fact that the enclosing device and the funnel-shaped insertion part are firmly connected to one another by a connection arrangement.
  • the enclosing device as well as the hose part and the funnel-shaped insertion part are expediently separable in the longitudinal direction. As a result, the entire device can advantageously be easily separated from the medical device used in each case.
  • Fig. 1 shows a greatly enlarged longitudinal section of an embodiment of a device according to the invention for medical use.
  • Fig. 2 shows a sectional view of the device shown in Fig. 1 along a section line A-A entered there.
  • FIG. 1 The sectional view of an embodiment of the device according to the invention shown on a greatly enlarged scale in FIG. 1 has a funnel-shaped insertion part 1 made of a solid material, such as a hard elastic see plastic, and an adjoining the insertion part 1 with its proximal end, that is to say placed on this elastic hose part 2, which has a round cross section and which preferably consists of polyethylene.
  • This tube part 2 forms below the transition area with the funnel-shaped insertion part 1 towards its distal end, that is the end shown in FIG. 1 below, a contact area 3 for a medical device, such as in particular a medical locking device.
  • a medical locking device is described for example in DE-199 42 951-C1; it has an oval cross-section in its working area.
  • the medical device in question can be inserted into the elastic tube part 2 through the funnel-shaped insertion part 1.
  • the hose part 2 and in the present case also the funnel-shaped insertion part 1 are surrounded by an enclosing device, the outer ring parts 4 and 5 here and below the mentioned transition area between the funnel-shaped insertion part 1 and the proximal end of the hose part 2 in the abovementioned contact area 3 has inner ring parts 6, 7.
  • the inner ring parts 6, 7 are mechanically connected to the outer ring parts 4, 5, such as, for example, by connecting webs, not shown here, which connect the inner and outer ring parts 4, 5, 6 and 7 to one another, as can be seen in FIG. 2 is.
  • the relevant inner and outer ring parts 4 to 7 and also the connecting webs can consist of a solid material, such as metal.
  • a plastic body 8 which consists of an elastically deformable plastic.
  • at least one separately activatable pressure element is embedded in the plastic body 8; in the present case two ro- tionally symmetrical pressure elements 9 and 10 are provided, which are each formed by inflatable air cushions and which are provided with connecting lines 11 and 12, respectively, through which compressed air can be discharged to the air cushions 9, 10 in question or compressed air contained therein can be discharged.
  • the relevant pressure elements 9, 10 are preferably embedded in the plastic body 8 and arranged in such a way that, when activated, they allow pressure to be exerted towards the center of the enclosing device 3.
  • the pressure elements 9, 10 in the present case each have a shape adapted to at least part of the outer shape of a medical device to be used in connection with the device in question in the present case.
  • the pressure elements 9, 10 each have a semicircular cross section, as can be seen from the sectional view according to FIG. 2. A good adaptation to an oval shape of a medical device is thus achieved, which can be inserted into the illustrated device according to the invention such that the longitudinal axis of the oval in question runs at right angles to the pressure elements 9, 10 according to FIG. 2.
  • the pressure elements 9, 10, in deviation from the conditions shown in FIGS. 1 and 2, can also each be formed by a mechanical pressure device which allows the hose part 2 to be compressed as desired.
  • Enclosure device with the outer and inner ring parts 4 to 7, as well as the hose part 2 and the funnel-shaped insertion part 1 can each be separated in the longitudinal direction, as can be seen more clearly from FIG. 2.
  • the U - locking device with its outer and inner ring parts 4 to 7 and the plastic body 8 is divided into two halves which can be pivoted about a rotary joint 13 and which are ner locking device can be locked, which has, for example, on the outer ring part 5 attached locking pawl 14 and on the outer ring part 4 receiving opening 15.
  • the hose part 2 and the funnel-shaped insertion part 1 can either also be separated in the longitudinal direction by a pivoting movement, like the arrangement considered above, or else, as usual, they can each be torn open in the longitudinal direction. This separation of the device described takes place in use when the device in question has fulfilled its lock function for the medical device used in each case, ie is no longer required for this function.
  • connection arrangement 16 which represents a non-positive connection arrangement, can be made, for example, by connecting webs running on the top of the plastic body 8 shown in FIG. 1 between the outer ring parts 4, 5 of the enclosing device and the funnel-shaped insertion part, or by one of the relevant outer ring parts 4, 5 and the funnel-shaped one Insert part 1 connecting cover part can be formed.
