Device for fixing a bent arm

on an anesthesia bar

The invention relates to a device for fixing a bent arm to an anesthesia bar, which has a vertical leg that can be fastened to an operating table and a horizontal leg that projects away from the vertical leg, with a tubular forearm cuff that can be suspended from the horizontal leg for fastening the forearm to the horizontal leg and a means for fastening the upper arm to the vertical leg.

In devices known from practice for fixing a bent arm to an anesthesia bar, only the forearm can be gently attached to the horizontal leg of the anesthesia bar by placing the forearm cuff around the forearm and hanging it on the horizontal leg of the anesthesia bar. The upper arm, on the other hand, is attached to the vertical leg with aids such as elastic bandages.

of the anesthesia bar. The elastic bandage is wrapped around the vertical leg of the anesthesia bar and the upper arm at the same time. Since the bent arm should be held relatively immobile on the anesthesia bar, the upper arm is fastened quite tightly to the vertical leg of the anesthesia bar. Tightly fastening the upper arm to the vertical leg of the anesthesia bar is not advisable, however, because this places a great deal of strain on the upper arm. If the upper arm is only loosely fastened to the vertical leg of the anesthesia bar so that it can be moved relative to it, this means that the forearm can also be moved relative to the horizontal leg of the anesthesia bar, in particular by slipping along the horizontal leg of the anesthesia bar. Such a change in the position of the forearm relative to the anesthesia bar can impair the feeding of an intravenous access on the forearm. Attaching the upper arm to the vertical leg of the anesthesia bar using an elastic bandage is also time-consuming. It also does not save material because the elastic bandage can only be used once for hygiene reasons.

The object of the invention is to further develop a generic device for fixing a bent arm to an anesthesia bar in such a way that the arm can be held relatively immobile on the anesthesia bar, whereby the attachment of the upper arm to the anesthesia bar is also carried out in a way that protects the arm.

The object of the invention is achieved in that the means for fastening the upper arm has a tubular upper arm cuff that can be fastened to the vertical leg and the forearm cuff and the upper arm cuff are connected to one another in an articulated manner.

The inventive effect of this solution is that the forearm cuff, and thus the forearm, are not only attached to the horizontal leg of the anesthesia bar, but are also attached to the vertical leg of the anesthesia bar via the articulated connection and the upper arm cuff. Likewise, the upper arm cuff, and thus the upper arm, are not only attached to the vertical leg of the anesthesia bar, but are also attached to the horizontal leg of the anesthesia bar via the articulated connection and the forearm cuff. In this way, the bent arm is held almost immobile on the anesthesia bar, and neither the upper arm nor the forearm has to be attached tightly to the anesthesia bar. The device according to the invention enables the entire arm to be positioned very gently on the anesthesia bar, and the arm joint is not subjected to any strain.

Preferably, the forearm cuff and the upper arm cuff are detachably connected to one another and the upper arm cuff can be exchanged for an upper arm cuff of larger or smaller diameter. The device according to the invention is therefore suitable for use both with patients with very voluminous upper arms and with patients with relatively slim arms.

Preferably, the forearm cuff or the upper arm cuff or both cuffs are adjustable in diameter and/or padded, whereby the device can be adapted to the shape and size of the forearm and/or the upper arm in order to enable a very gentle positioning of the arm on the anesthesia bar.

Preferably, the forearm cuff and/or the upper arm cuff or both cuffs have a moisture-impermeable, dirt-repellent, flexible surface material made of plastic, whereby the device is easy to wipe down and disinfect. The

The surface material of the forearm cuff and/or the upper arm cuff preferably consists of a high-strength polyester fabric with a one-sided PVC coating with a dirt-repellent finish. Such a material is commercially available, for example, as a lightweight tarpaulin for watercraft.

In order to be able to easily attach and detach the forearm cuff and/or the upper arm cuff to the anesthesia hanger, it is expedient if the forearm cuff and/or the upper arm cuff can be attached to the anesthesia hanger by means of one or more loops made of tape material attached to the respective cuff, and if each loop can be opened and re-closed and is adjustable in length.

Preferably, each loop has Velcro fastener parts that interact with each other.

An embodiment of the invention is shown in the drawing and is described in more detail below. It shows

Fig. 1 shows a schematic representation of a device 1 for fixing a bent arm 2 of a patient (not shown in detail) lying on an operating table (not shown) to an anesthesia bar 3, which has a vertical leg 4 and a horizontal leg 5 that protrudes from one end of the vertical leg 4. The other end of the vertical leg 4 is attached to the operating table (not shown) in a height-adjustable and adjustable manner. The device is used to support the arm in the form shown during anesthesia of the patient. The device has a tubular forearm cuff 6 which encloses the forearm 7 of the patient and is suspended from the horizontal leg 5 of the anesthesia bar 3 by means of two loops 8a and 8b described in more detail below in order to hold the forearm 7 of the patient on the horizontal leg 5 of the anesthesia bar 3 substantially parallel to the horizontal leg 5 of the anesthesia bar 3.

As can be seen in particular from Fig. 2, the forearm cuff essentially consists of a flexible mat-like body 20, which is originally flat and rectangular and has then been made into a tube shape by moving its opposite shorter sides 21a, 21b towards each other. The body is held together in the tube shape in a way that is adjustable in diameter by two bands 22 fastened to the outside of the tubular body 20 of the forearm cuff 6, each of which has a free end 23 that can be passed through two eyelets 9a and 9b fastened adjacent to one short side 21b of the tubular body 20 of the forearm cuff 6. At one end of each band 22, which is attached to the outside at a distance from the other short side 21a of the body 20, there is a band-shaped Velcro fastener part 24 with hooks. The free ends of the bands, which are guided through the eyelets 9a and 9b, are made fluffy on their outside. Each free end of the respective band

22 is, after it has been passed through the respective eyelet 9a or 9b, folded over in the opposite direction by 180° and pressed onto the Velcro fastener part carrying the hooks, so that the fluffy side of the free end of the band 22 engages with the Velcro fastener part 24 carrying the hooks. Depending on how long the section of a band 22 is that is pulled through the respective eyelet 9a or 9b, and how far the Velcro fastener part carrying the hooks is overlapped by the free end 23 - viewed in the longitudinal direction of the band - a smaller or larger diameter of the tubular body 20 of the forearm cuff 6 results, the diameter of the tubular body 20 of the forearm cuff preferably being selected so that the forearm cuff 6 encloses the forearm largely without pressure. The two free ends of the straps 22 can be brought into engagement independently of one another with the Velcro fastener parts 24 carrying the hooks, which opens up the possibility of setting the diameter of the tubular body 20 to different sizes in the area of the straps and the respective eyelets 9a and 9b, so that the tubular body 20 of the forearm cuff 6 can be given a conical shape corresponding to the conical shape of the respective forearm 7.

As can be seen in particular from Fig. 3, each loop 8a or 8b, with which the forearm cuff 6 is suspended from the horizontal leg 5 of the anesthesia bar 3, has a band 30 running around the tubular body 20 of the forearm cuff 6, which is fluffy on its outside and is fastened to the outside of the tubular body 20. At a free end of each band of the respective loop 8a or 8b there is an eyelet 31, and at the other end of the corresponding band a band-shaped Velcro fastener part 32 carrying hooks is fastened. The loop 8a or 8b is closed by passing the Velcro fastener part 32 carrying the hooks through the respective eyelet 31 of the loop and into the

The loop 8a or 8b is folded over in the opposite direction by 180° so that the hooks come to rest on the fluffy surface of the band 30 of the loop 8a or 8b. The horizontal leg 5 of the anesthesia bar 3 is guided through the opening 33 of the loops 8a and 8b. Depending on the length of the band-shaped section that is guided through the eyelet 31 of the loop 8a or 8b and the distance from the eyelet 31 at which the Velcro fastener part 32 carrying the hooks engages with the fluffy side of the band 30, a larger or smaller opening 33 of the loop 8a or 8b is produced. The size of the opening of the loop 8a or 8b in turn determines the distance of the forearm cuff 6 from the horizontal leg 5 of the anesthesia bar 3. The two loops 8a and 8b can be adjusted independently of one another with regard to the size of their openings, which makes it possible to change the position of the forearm cuff 6 in relation to the horizontal leg 5 of the anesthesia bar 3b so that, deviating from the parallel position shown in Fig. 1, it can also run slightly inclined relative to the horizontal leg 5 of the anesthesia bar 3.

The device for fixing the bent arm 2 to the anesthesia bar 3 also has a tubular upper arm cuff 10 which surrounds the upper arm 11 and is attached to the vertical leg 4 of the anesthesia bar 3 by means of a loop 12. The upper arm cuff 10 is connected to the forearm cuff 6 in an articulated manner by a loop 13. The point where the forearm cuff and the upper arm cuff 10 are connected is in the crook of the arm, as shown in the drawing. The upper arm cuff 10 essentially consists of a flexible, mat-like body 40 which originally had a flat rectangular shape and was made into a tubular shape by moving its two short side edges 41a, 41b towards each other. The tubular body 4 0 of the upper arm cuff 10 is secured by a band 13 which is attached to the outside of the tubular

shaped body of the upper arm cuff 10 and having a free end 13a, and held in the tubular shape by an eyelet 14 which is fastened to a short side edge 41b of the tubular body of the upper arm cuff 10, in that the free end 13a of the band 13 is passed through the eyelet and folded back by 180° in order to reach, with a side formed from a fluffy surface, a band-shaped Velcro fastening part 13b which carries hooks and which is also fastened to the outside of the tubular body of the upper arm cuff 10. The upper arm cuff 10 is adjustable in diameter by changing the length of the section of the band 13 passed through the eyelet 14 and its fastening point on the Velcro fastening part 13b which carries hooks. By changing the diameter of the upper arm cuff, the upper arm cuff 10 can be adapted to the circumference of the patient's upper arm 11 so that the upper arm cuff encloses the upper arm with as little pressure as possible.

The loop 12 has a band 50 attached to the tubular body of the upper arm cuff 10, at one end of which there is an eyelet 15 and at the other, free end of which a band-shaped Velcro fastener part 51 with hooks is attached. Between the hook-bearing Velcro fastener part 51 and the eyelet 15, the band 50 has a fluffy surface. By passing the hook-bearing band-shaped Velcro fastener part 51 through the eyelet 15 and by folding the section passed through in the opposite direction by 180°, the side with the hooks of the band-shaped Velcro fastener part 51 comes onto the fluffy surface of the band 50 and forms a detachable connection with it. The loop formed by the band 50, the eyelet 15 and the hook 51 surrounds the vertical leg 4 of the anesthesia bar 3. The size of the opening of the loop can be adjusted by changing the length of the section passed through the eyelet 15 and the

Fastening point of the hook-bearing Velcro fastener part 51 on the band 50 is adjustable.

The loop 13, which connects the forearm cuff 6 and the upper arm cuff 10, consists of a band with a fluffy surface, which is attached to the upper arm cuff 10 and has a free end to which a band-shaped Velcro fastener part carrying a hook is attached. In addition, the loop 13 has an eyelet attached to the forearm cuff 6, through which the Velcro fastener part carrying a hook is passed and folded over in the opposite direction by 180°, so that the Velcro fastener part carrying a hook is releasably engaged with the fluffy surface of the band attached to the upper arm cuff.

Both the forearm cuff 6 and the upper arm cuff 10 consist of a padded mat-like body, the opposing walls of which consist of a PVC-coated polyester fabric, between which a padding material is enclosed. The surface of both cuffs is dirt-repellent, impermeable to liquids and disinfectable. The loop 13, which connects the forearm cuff and the upper arm cuff, is detachable, whereby the upper arm cuff 10 can be exchanged for another upper arm cuff of larger or smaller diameter.
