Definitions
- the invention relates to a combination of
- an intra-uterine contraceptive device (i) an intra-uterine contraceptive device, (ii) a corresponding hollow insertion device with interior for the insertion of the contraceptive device into the uterus, and (iii) an at least partially arranged in the insertion device
- Pressure device with pressure-transmitting material the pressure device having its cranial end abutting the caudal end of the device, the contraceptive device consisting of an elongated cuboid or cylindrical body and at least two flexible arms which are attached to the cranial end of the body, and wherein the insertion device has at the cranial end an elongated opening at the start of opening and at the level of the opening at least one web that thickens at the cranial end of the web.
- the intra-uterine contraceptive device can e.g. to be a pessary.
- the pessary is pushed through the opening into the lumen of the uterus using a pressure device in the form of a piston, which is arranged almost completely in the interior of the insertion device.
- the arms reach the area of the opening and unfold.
- the body of the pessary is then also pushed out of the opening.
- the insertion device with piston is then pulled out of the uterus.
- a disadvantage of the device is that the fundus uteri can be injured when the rather rigid combination is introduced. Furthermore, there is a risk that when the insertion device together with the piston is removed, the device is also pulled out of the uterus. Faulty positioning of the device is possible at any time since the device can twist when it is ejected from the insertion device.
- the object of the invention is to offer a combination of an intra-uterine contraceptive device, an insertion device and a printing device, the combination allowing a safe, injury-avoiding and tolerable introduction for women.
- the position of the intra-uterine contraceptive device should be predeterminable.
- the object is achieved by a combination of the type mentioned in the introduction, in which the introducer and at its caudal end have brackets, the web is pressure or bending elastic, the web has a guide for the device and / or the opening does not start perpendicular to The axis of the insertion device runs and / or the interior of the insertion device is not rotationally symmetrical.
- cranial and caudal mean the following: cranial points towards the uterus, caudal points away from the uterus. If the interior of the insertion device is not rotationally symmetrical, at least parts of the device must have a cross section that is complementary to that of the insertion device, so that twisting of the device relative to the insertion device is excluded. If one speaks of the longitudinal axis and cross section, these expressions are defined by the arrangement of the entire combined combination. The longitudinal axis runs parallel to the longitudinal direction of the interior of the insertion device. The cross section is perpendicular to it. The combination according to the invention has various advantages.
- the resilient web significantly reduces the risk of injury when inserting the insertion device. Even if the fundus uteri is touched by the introducer, there is a risk of injury, e.g. B. a perforation, significantly reduced.
- the elasticity avoids lesions, but still allows the doctor to feel whether the upper wall of the uterus is touched or not.
- the elasticity can consist in length elasticity (volume elasticity). Soft plastics or springs are available for this. Bending elasticity is also possible, in which an angled web can absorb forces with respect to the longitudinal suspension. Lateral fluctuations caused by a restless hand by the doctor will also no longer be dangerous, since here too the resilient property of the bridge reduces lesions.
- the mutual alignment of contraceptive device and insertion device has the advantage that the arms of the device can unfold in a manner to be determined in advance and at the same time be visible on the insertion device.
- the uterus is bilaterally symmetrical.
- the two arms of the device should unfold in the direction of the tube angle. Unfolding by 90 ° can result in injuries or incorrect seat of the device. Guiding the web offers a similar advantage.
- the device slides on this guide. Since the arms and the body of the guide rest, a substantial rotation of the device in relation to the insertion device is avoided.
- the combination of the features leads to a superiority of the combination according to the invention compared to the prior art.
- the features serve synergistically to precisely determine the position of the device spatially and to reduce the risk of injury when it is introduced.
- a combination according to the invention is advantageous in which the pressure device is a piston which is essentially arranged in the insertion device, in cross section at least partially complementary to the insertion device and is movable relative to the insertion device and which abuts the caudal end of the device with its cranial end, and in which the insertion device and the piston each have brackets (13 and 19) essentially at their causal ends.
- the piston or the device can slide relative to the insertion device without any problems and has a sufficiently secure guidance during the sliding.
- the brackets on the insertion device and the piston enable one-handed operation. It is also advantageous to determine the position of the device by means of this holder. Since the device cannot be freely rotated relative to the insertion device, the doctor can determine the position of the device by orienting the holders on the insertion device.
- the one-handed handling is more advantageous than the two-handed, because counter-forces can be regulated more finely in one hand.
- the arm muscles involved in two-handed handling are not capable of fine motor skills.
- a combination according to the invention in which the body is a container is advantageous.
- the container takes on the function of a depot which gradually releases the substances.
- This container can have at least one semi-permeable wall.
- the substance can penetrate through this wall in a dissolved form, but not in a crystalline form.
- the time required for going into solution in order to achieve a reasonable dosage can be determined by appropriate galenics.
- the container can have at least one opening. This can be the case when administering e.g. healing medicines that are supposed to act locally.
- the web is S-shaped.
- a comparable effect can be achieved if the bridge is angled. It is desirable that the arms of the contraceptive device can unfold easily. This is achieved by a combination according to the invention in which the thickened web end is wedge-shaped and points caudally with the tip of the wedge.
- the wedge is preferably designed like a snow plow.
- a further advantageous embodiment consists in the fact that the piston and the insertion device are at least partially non-rotationally symmetrical in the overlapping sliding area.
- the sliding area can also be composed of several partial areas.
- the sliding range is defined by the extreme positions of the piston and insertion device. The one extreme position arises when the device has been completely removed from the insertion device, the other extreme position when the device is completely drawn into the insertion device.
- the non-rotationally symmetrical areas of the piston and insertion device prevent the piston from rotating relative to the insertion device. This has the advantage that the doctor can exert further influence on the insertion device even with the holder of the piston. This increases the safety of one-handed handling.
- the simplest embodiment is that the piston is at least partially bilaterally symmetrical.
- the arms of the device In order to reduce the risk of injury when the arms unfold, it is advantageous if the arms of the device have thickenings at their ends.
- the holders of the insertion device can be part-circular, furthermore also semicircular or circular.
- the holder of the piston can be part-circular, also semicircular or circular.
- the optimal shape of the brackets can easily be determined by ergonomic studies.
- FIG. 1 shows the combination; here is the device and the Piston in supervision, and the insertion device seen in side view; (The cranial area in this part of the introducer is rotated 90 ° with respect to the caudal area with respect to the longitudinal axis of the device).
- FIG. 2 shows the cranial end of the introducer in side view.
- Figure 3 shows the cranial end in a side view (rotated 90 ° to Figure 2) and Figure 4 shows a sectional drawing through the combination, which is partially in the uterus.
- FIG. 1 shows the combination 100, which consists of an intra-uterine contraceptive device 1, an introducer 2 and a piston 3. All three elements of the combination 100 are arranged in FIG. 1 so that the cranial part of the elements points upwards.
- the device consists of a cylindrical body 4, which is partially surrounded by a copper spiral 5, and of two flexible arms 6 and 6 ' , which are spread apart in the relaxed state and extend approximately 90 ° to the body 4.
- the arms are attached to the cranial end of the body 4.
- the arms 6 and 6 ' end in thickenings 7 and 7 ' .
- the introducer 2 consists of a tube 10, each having an opening 11 and 12 caudally and cranially. Above the caudal opening 11 there are two device holders 13 and 13 ' .
- the cranial opening 12 is elongated and has a beveled opening start 23. These parts of the insertion device are shown in detail in FIGS. 2 and 3.
- the device 2 Over the length of the cranial opening, the device 2 consists of a web 14 which first runs parallel to the device axis 15, then is angled toward the device axis, in order finally to terminate in a thickened web end 16. The center of gravity of the thickened web end 16 lies approximately on the implement axis 15.
- the thickened web end 16 has a tip 17 with a wedge on its part pointing towards the caudal end, the curved side walls 18 and 18 'of the wedge being designed like a snow plow.
- the opening beginning 23 shows a gate running obliquely to the device axis 15. The part of the opening opening facing the web points more cranially than the part pointing away from the web.
- the piston 3 has at its caudal end a piston holder 19 which is semicircular.
- the combination 100 is handled as follows.
- the doctor uses a probe to determine the distance between the upper cover of the uterus and the mother's mouth. This distance is held by a slide 21 which can be displaced on the insertion device 2.
- a corresponding length scale on the introducer 2 facilitates the setting.
- the doctor receives the combination that has not yet been merged.
- the plastic threads 9 and 9 ' are pushed into the cranial opening 12 of the insertion device 2 and pulled out of the caudal opening 11.
- the body 4 disappears in the interior of the insertion device 2, then the flexible arms 6 and 6 '.
- the arms are transferred from the spread shape to the folded one.
- the arms 6 and 6 ' are now parallel and in the direction of the device axis 15.
- the force for folding the arms 6 and 6 ' is exerted by the inner tube wall of the insertion device 2.
- the piston 3 is then pushed into the insertion device 1.
- the composite combination 100 is inserted through the vagina and cervix into the uterus.
- the slider 21 should prevent the thickened web end 16 from abutting the inner wall of the uterus. However, if this is the case, the stress on the tissue that occurs will be low.
- the thickened web end 16 distributes the pressure over a large area.
- the bridge -14 is designed to be resilient, especially the angling has a positive effect.
- the introducer 2 is pulled out of the uterus.
- the plunger 3 maintains its position about the uterus, ie it moves relative to the insertion device 2.
- the body 4 of the device 1 has left the introducer 2 through the cranial opening 12, the introducer 2 and the piston 3 are removed from the uterus. The insertion process is now complete.
