Abstract

The Push-off dialysis serves to seal punctured blood vessels after dialysis. she is characterized in that a toothed spindle (4) with a loosely mounted Abdrückeller (10) presses on the punctured spot until the bleeding is breastfed is.

Description

In dialysis will make people alive through a dialysis procedure receive. The blood of the patients is cleaned in a machine and returned to the patient's bloodstream. There are two puncturing needles on a blood vessel of the patient stated. The thickness of the puncturing needles can be up to a diameter to 2 mm. At the end of this blood purification, the patient is removed from this machine disconnected again.

The Open puncture sites are usually taken by the patients themselves pulled the trigger. After about 10-15 Press minutes, the bleeding is generally breastfed. For some reason there it is patients who are unable to squeeze the blood vessel themselves. These Activity takes over the carer or the nurse.

at All these jobs are done with clean rubber gloves.

I am also a dialysis patient and have come up with the idea to construct a Abdrück-device. Maybe this device can use the nursing service.

Base:

The Base plate is curved and has a slot at each end to receive a fastening strap. At one end of the slot, the band is firmly connected, at the other end of the slot the tape runs over one Roll and is fixed with a velcro.

At The underside of the base plate has two cleats attached to it a pressure on the puncturing needle during the removal of the puncturing needle should prevent.

On the top of the base plate, the backstop is attached. she is soldered to the base plate with a solder hard

Spindle gear:

The Toothed spindle is part of the backstop. She is half-sided toothed and has the task of pressing the puncturing the returns to block. At the bottom of the spindle is a loose disc mounted to press on the sterile dressing of the puncture site. On the upper side of the spindle, a disc is firmly mounted, the to press and turning is used.

Of the bead breaker can be done when the teeth of the spindle are locked in the backstop.

By a rotation of the spindle by 180 degrees, the backstop is lifted. Now you can steplessly press and at the necessary pressure, the spindle turns 180 degrees in the backstop locked again.

BACKSTOP:

To the backstop belongs also the locking bar. He has the task, the toothed spindle only one Way to release and forward. The return is blocked.

At each side of the backstop is ever a tension spring mounted, which ensure that the locking bar always engages in the toothing of the spindle.

On the backstop a handle plate is screwed on. She gives the departure Fingers a stop. Furthermore the coil springs are attached to this plate.

Important: Before using this device Make sure that the locking latch is in the correct position is.

It can also spindles with a finer toothing can be used. The Practice would it shows what need is there. This ejection device has the Advantage that it is created quickly, the nurse both Hands to fire has free and at the same time remove the puncturing needle and can squeeze.

To When the puncturing time is over, the spindle is rotated 180 degrees and the blocking is canceled.

Should the puncture not yet tight, is pressed again and locked.

Of the Prototype of this device is made of the precious metal V2a. Sure you can Device too made of plastic, if the material is the temperature of the safely resists medical cleaning.

Between bead breaker and the sterile dressing of the puncture site, you can also get a sterile Insert gel cushion. With this use you can the Abdrückstelle round off the punctuation.

Claims (5)

The dialysis ejector serves to seal punctured blood vessels after dialysis. It is characterized in that a toothed spindle ( 4 ) with a loosely fitted Abdrückellenteller ( 10 ) press on the dotted spot until the bleeding is stopped. The backstop ( 2 ) according to protection claim 1 is characterized in that a locking bar ( 11 ) in the teeth of the spindle ( 4 ) and blocks the return of this spindle. A rotation of 180 degrees on the rigid turntable ( 5 ) of the spindle against the spring tension of the locking bolt, the spindle releases from the unilateral blocking. The pressure plate is pressed with the spindle onto the puncturing point. At the same time, the puncture needle can be removed from the blood vessel. Further rotation of the spindle through 180 degrees locks the spindle in the existing pressure. The hemostasis can be controlled by loosening and re-locking the spindle. The base plate ( 1 ) according to protection claim 1 and 2, characterized in that the plate consists of metal and has a slight curvature. The backstop and the distance lugs are mounted on this base plate. At the ends of the base plate slots are provided for the mounting of the fastening straps. A recess on the base plate provides a visual overview. The tunnels ( 7 ) for protection claim 1, 2 and 3, characterized in that there is no pressure on the puncturing needle during the Abklemmvorganges. The studs are made of plastic The suspension ( 9 ) for protection claim 1, 2, 3 and 4, characterized in that the spring tension constantly presses on the toothed spindles and holds the locking bar in its position.
