Abstract

compression apparatus to occlude a groin artery after angiography or intervention, characterized in that the supporting part is adjacent to the patient standing tripod is, whose bottom plate under a buttock half lies and is made of flexible material that suits the body shapes a little bit adjusting, but a vertical orientation of the tripod guaranteed.

Description

diagnostic and therapeutic interventions on the vasculature in the great majority with access via the groin arteries carried out. The closure of the opening in the Vascular wall is done conventionally by manual compression. Today one uses for the outer one Compression often simple mechanical apparatus, or you close the vessel wall immediately through a suture or similar measures on the vessel wall. The The latter measures require regular at least 2 mm wide opening in the vessel wall, why after surgery with smaller catheters or locks after as before the external compression for hemostasis is preferred.

State of the art

The older one of two known compression systems, possibly is no longer commercially available, consisted of a tripod with a rigid bottom plate under the buttocks of the patient, an arm of not variable length, by tilting in a rail was locked to the tripod, and a plastic disc at the end of the Arms using the tripod pressed to the puncture site has been.

The correct placement was difficult because always the whole apparatus had to be moved. And the pressure was only very roughly adjustable. Added to this was the harassment of the patient by rigid pressure plate and rigid bottom plate.

The second system, which is predominantly used today, becomes fixed to the patient by a cross over the body extending temple, held on both sides by a under the patient lying belt. In the hanger is over the puncture site an inflatable pad used by a Hand pump is filled, controlled by a pressure gauge. (Femostop II Plus, RADI Medical Systems, Palm Blagsgatan 10, Box 6350, 751 35 Uppsala, Sweden).

Also here the placement does not always succeed because of the location of the pad determined by the previously underlying belt. Main disadvantage of this But systems are the high running costs, because for everyone Patients a new pad and a new strap is needed.

A incorrect placement of the print is, if it occurs, on most likely due to the fact that the part of the system that controls the pressure transfers to the skin, not independently can be placed from the remaining parts of the apparatus.

In the invention for which protection is sought in the protection claims, in the first step, a compression pad (utility model application AZ 20 2008 016 500.8 ) are still optimally localized and fixed on the skin independent of the apparatus. Only then is the pressure generating apparatus set up above this cushion, without any spatial restrictions.

Of the Pressure can be achieved precisely by a simple screw mechanism and be set reliably.

The pressure is applied to the compression pad AZ 20 2008 016 500.8 transmitted by a slightly domed cap, which consists of Plexiglas or a similar transparent material. On the inside of this cap a pressure gauge is mounted in the vertex of the bulge, connected to a digital display on the tripod arm

Of the The patient lies on one buttock half on flexible finger-shaped strips of elastic steel or similar material, covered by a cloth, the one wear stand-up tripod next to the patient. On this tripod is an adjustable in height and length and direction Arm attached wearing the cap at its free end, which exerts the pressure on the compression pad.

The Elasticity, which is a gas-filled pressure pad has, is desired. When liquid-filled pressure pads should be used, the force of the screw, with which the Pressure is adjusted, be resiliently cushioned, z. B. by a coil spring.

• 1. Der entscheidende Vorteil ist, dass der Ort der Kompression ganz unabhängig von den anderen Teilen des Systems gewählt und festgelegt wird.
• 2. Exakte und zuverlässige Einstellung des Kompressionsdrucks (kein Druckverlust durch ein Leck in einem pneumatischen System).
• 3. Verbesserung des Patienten-Komforts durch Flexibilität der das Stativ tragenden Unterlage (Bodenplatte), auf welcher der Patient liegen muss.
• 4. Die Ausführung des Stativs in Teleskop-Form erspart ein hohes Stativ, das unter keine Bettdecke passt.
• 5. Nur wenig Einmal-Material (Gebrauchsmuster – Anmeldung AZ 20 2008 016 500.8 ), das preiswert herzustellen sein dürfte. Dadurch geringe laufende Kosten.

Compared to other systems on the market, the compression method described here has several advantages:

• 1. The key advantage is that the location of the compression is chosen and determined independently of the other parts of the system.
• 2. Accurate and reliable adjustment of compression pressure (no pressure loss from a leak in a pneumatic system).
• 3. Improvement of patient comfort through flexibility of the stand supporting base (base plate) on which the patient must lie.
• 4. The design of the tripod in telescopic form saves a high tripod, which does not fit under a duvet.
• 5. Only a small amount of disposable material (utility model - application AZ 20 2008 016 500.8 ), which should be inexpensive to produce. This low running costs.

Practical use

After completing the procedure, the patient will be in a recumbent lock (or catheter) Bed and placed on the bottom plate of the tripod. The patient must be able to lie comfortably for a few hours on the base plate of the tripod. The cloth with which the plate is covered with respect to the body (a cloth or the like.) Should, for. B. have no wrinkles. Then the sterile compression pad is placed on the puncture site, the surrounding foil spread, and the pad with the self-adhesive surfaces of the surrounding foil fixed on the skin (Utility Model Application AZ 20 2008 016 500.8 ).

Now First, the upper part of the tripod with the tripod arm in the lower Part of the tripod pushed and set up so that the transparent cap with the pressure gauge centrally on the compression pad lies. The arm is used with moderate force against the Compression pad pressed and then fixed to the tripod.

After that Using the screw mechanism, the pressure on the compression pad built up until the pressure gauge displays a value in the amount of indicates systolic pressure or until the signal at a peripheral leg-mounted pulse oximeter becomes weaker or completely disappears. All this is done carefully as long as the puncture site is still secured by lock or catheter.

Then sluice or catheter are pulled and if necessary the pressure so increased to a possibly still observed bleeding completely stands. After 2-3 minutes, the pressure is reduced so much that the pulse oximeter shows a normal signal again. simultaneously visual control of the puncture site on the skin for exclusion a bleeding. In the next 5-10 minutes two- up to three times further pressure reduction, up to - for Patients with average blood pressure - a value of about 80 mmHg is reached. If no bleeding is evident then and the peripheral control may show normal blood flow the patient is brought to the ward. There about half-hourly Controls. After 4-5 hours, the compression in the Usually be removed.
