Tourniquet

The invention relates to a tourniquet, i.e. a device intended to be wrapped around a limb to be attached and cut off the flow of blood. The device is also suitable for being placed around a male reproductive limb and for blood circulation to restrict and thus to bring about the erection of the member, if the man or the male animal is impotent or only is weakly potent.

The main task on which the invention is based is seen in the fact that such a device is provided which is able to exert a pressure that is evenly distributed around the limb or organ, a device that can easily apply pressure and on

109818/1198

can be easily solved again, which engages determined and safely in the particular closed position and the is easy to set up and use.

Many tourniquets are already known. * For example, U.S. Patents 1,073,525 and 1,225 Tourniquets are described which are to be used on a male reproductive organ for the specified purpose, the but only exert the pressure in certain places on the organ and so an unsatisfactory control of the blood circulation through the organ, in addition to which they can still be uncomfortable or painful for the user.

A later described in US Pat. No. 2 6O4 O98

k written solution that should be used to stimulate the bloodstream By completely cutting off a limb, the pressure is applied somewhat more uniformly, but still predominantly the pressure acts on the limb on two opposite sides, creating imperfect blood circulation control occurs, The described in this patent, bene device works so that a strap around the limb is tightened around like a waist strap. Apart from the fact that there is tenacity, that the pressure is on

10981 8/1198

occurs in certain places, such a strap pulls the skin also in columns, which gives rise to pain for the user can be.

Furthermore, in U.S. Patents 2,04-5,750 and 2,468,133 similar devices using flexible tubing attached around the limb must be, whereupon air is then forced into this hose to bring it to the trigger itself. These Devices avoid the disadvantage of local pressures. However, they have the disadvantageous fact that they are a Need pressure medium source, including either a pump or a pressure medium container are required, which are separate from the tourniquet itself must be accommodated. aside from that malfunctions can occur more easily here than with the previous ones mentioned mechanical devices. They are also completely useless for use on impotent or weak people potent males.

With the invention are the aforementioned difficulties corrected by creating a fully self-retaining tourniquet in which the pressure is even around the member or the male reproductive organ means

mechanical pressure medium is exerted, the pressure can be controlled mechanically as desired, making a very reliable and an easy-to-use device is created.

More precisely, the tourniquet according to the invention has a ring which forms a torus-shaped chamber which contains an inner elastic, stretchable wall which is pushed over the limb or male organ mechanical, the pressure-exerting means are available, which on the resilient wall of the chamber exert a substantially uniform pressure and which is within the Chamber are located, whereby the elastic wall is expanded inwardly against its elastic restoring forces, so that the diameter of the inner ring opening is veslngerto Von ..., the outside of the ring is a mechanical control device attached to the ring itself, which with the mechanical, the pressure executive means is connected, so that on the way the The amount of pressure exerted on the resilient wall is exercised, is controllable and thus also the size of the ring opening.

In a preferred embodiment, the ring consists of a rigid annular support and the aforesaid elastic wall, the latter being an endless membrane

with side edges attached to the side edges of the support ring on the inside, thereby forming the toroidal chamber. The carrier ring has on its inner surface to guide grooves _r and the mechanical, pressure-feeding means is provided with a ring member inserted into the grooves and is rotatable relative to the carrier ring. Finally, there are several bands in the chamber, one end of which is attached to the ring element so that they can be rotated with it, while the other end of the band is fixed to the carrier ring. The ends of the bands are distributed around the circumference of the ring element and the carrier ring, whereby rotation of the carrier ring in a certain direction causes the bands to close tightly around the membrane and exert a force which causes the membrane to contract in the manner of an iris diaphragm.

From the following description of one in the drawing illustrated embodiment, the invention is again clear. Show it:

Means have a ring element 9 which is rotatable relative to the Carrier ring 3 is attached on the inside. How on Can best be seen from Fig. J5, the ring element 9 is along its outer edge provided with a toothing. Multiple bands 11 create for the inward expansion of the elastic wall 5 the required pressure. One end of this bond is on that

Ring element 9 attached in any way so that / together can be rotated with the ring. The other end of the ribbons 11 is connected to a fixed part, which can be regarded as part of the carrier ring 3, which will be discussed later will be discussed in more detail.

The bands 11 preferably consist of short steel wire · pieces that are covered with a nylon tube.

The support ring 3 has guide grooves on the inner surface provided, in which the rotatable ring element 9 is inserted .. This Guide grooves are made by a pair of outer rings 13 and 15 and a pair of inner rings 17 and 19 are formed. The outer ring 15 has a sloping edge 21, .with which he against a correspondingly inclined shoulder of the support ring 3 rests. The inner side wall of the outer ring I3 has a fial circular shape Groove 23 into which a correspondingly shaped bead 23 of

109810/1198

elastic wall 5 is inserted. One of the inner rings 17 lays itself against this bead 25 and holds it in the groove 25 fixed. The ends of every second band 11 are connected to this ring 17.

* A similar setup is on the opposite side of the support ring 5 is provided. There is therefore the second inner ring 19 * to which the ends of the remaining bands 11 are attached are, while the second outer ring I5 with a similar one semicircular groove 25 for receiving a bead 25 the second edge of the elastic inner wall 5 is provided.

Rings I3, 17, I9 and 15 have guide slots 27, 29, 51 and 35 (Figure 3), in which a wedge 57 (Figo 5) engages., which also lies in a keyway 55 on the inner surface of the support ring I3. In this way the rings 1-j5, I7, and 15 held against rotation relative to the support ring 5, so that they can be viewed as part of the support ring which they form the guide grooves «. On the other hand, it is ensured that the rotatable element 9 is in this guide · can rotate freely between the inner rings 17 and I9 »

The earlier mentioned mechanical control means with which the rotatable ring element 9 can be rotated, have a pinion 59, which with sdnen teeth into the teeth of the ring element 9 engages and is rotatably mounted on an axis 41 is, which is passed through eyes 45, which at a Point outwards from the carrier ring.

The arrangement that forms the guide grooves is by an elastic wire or the like 47, which in a Circumferential groove in the support ring 3 and in the outer ring $ 5, like the Pig. 2 shows prevented from slipping out of the support ring j5.

So that the pinion 39 act on the rotatable ring element 9 can be found in rings I3, I7, I9 and I5 corresponding locking recesses 49, 51, 53 and 55.

In the arrangement shown in Figs it can be seen that when the pinion 39 is rotated "counterclockwise." (i.e. in the direction of arrow a in Fig. 5) the ring element 9 is rotated clockwise, i.e. in the direction of arrow b, wherein the band ends attached to the ring element are rotated, while the other ends of the bands 11 at the fixed

Elements are attached, making them then on the ring-shaped elastic wall 5 press, and while the various bands enclose a circle, as shown in Fig. 4, is at as the pinion 39 is turned further, the circle becomes smaller and smaller. In this way the iris-like aperture is closed and works with a pressure evenly distributed around the circumference on all Place the ring opening.

Fig. 5 shows in detail a locking device which is used to fix the elastic wall 5 in a certain position against its own elastic force Length is such that it fits into the teeth of the pinion 39 in the Pig. Can / engage V shown 5 else "with a push button 13," ^de extends through the support ring 3 and is riveted on its inner side, so that it can not fall out of the support ring 3, the leaf spring pawl 57 can be pivoted out of engagement with the pinion 39 (position shown in dashed lines in Fig. 5).

In the case of vein presses of larger dimensions, the ends of the axle 60 can have polygonal depressions in which to rotate

of the pinion 45 then a corresponding polygonal key can be introduced.

With the arrangement described, an extremely simple, effective and safe tourniquet is created. By closing the central opening of the ring 1, the necessary pressure is exerted on the limb or organ, so that thereby the blood circulation can be controlled to the desired extent. If the pressure is made high enough, the blood circulation can completely to be interrupted. In addition, if there is sufficient pressure when using the tourniquet on a male reproductive organ is exercised near the urethra, it can also prevent the sperm from escaping, thereby blocking the tourniquet can then be viewed as a contraceptive tool.
