THE PATIENT'S SllRTUOLL

The invention relates to a patient transfer chair comprising a chair body, wheels for inserting a body frame and two substantially horizontal rods extending at the top of the body to position a seat member on said rods by threading tubular formations at the ends of the seat member.

A wheelchair transfer chair of the kind described above is known from U.S. Patent 10 3,914,808, wherein the transport chair shown comprises a frame with a single vertical mast mounted on a. height-adjustable, vertical mast support bars for a seat portion that can be detached from and retracted from the support bars, the seat portion comprising tubular formations at each end.

• * 15 The disadvantage of the known solution described above is the discomfort of the seat portion when seated, as the patient has to sit on an entirely oversized seat portion relative to the distance of the bars. While seated in a deep hanging position, despite the support devices shown in the publication, the seat unit presses down and causes the seat fabric to squeeze the seat. Sitting is uncomfortable and there is no leaning back support. On the other hand, if the seater is seated on 20 devices in a deep uncomfortable hanging position, the seat support bars may, according to the publication, act as armrests. Due to the constant distance between the bars lifting the seat unit, the lifting and lowering movement must be very large so that the patient sitting on the bed edge rises enough to leave the bed and, on the other hand, get back to the bed edge. The seating unit described in * · '25 and its support bar solution results in a relatively high body rack when it is practically possible for a patient sitting in a deeply suspended position to be lifted at least for each seating position due to various displacements, chair changes, toilet seat transfers. until.

,. The patient transfer chair of the invention provides a significant improvement in the usability of the seat portion, a reduction in the required lift heights and device body dimensions *, and an improvement in the attachment of the attachments. It is a characteristic of the invention that the t a f • · transfer chair includes rod moving devices, such as an eccentric mechanism, by which the * rods can be spaced relative to one another.

An advantage of the transfer chair according to the invention is that, with a relatively small movement of sliding the support bars, the seat fabric mounted on the bars tightens between the bars almost horizontally, raising the patient sufficiently from the base. With high-tensioned seat-5 cabbage, it is comfortable to sit. The patient can be seated in a seated position in both the front and rear, and the necessary recliners can be attached to the chair in all cases. When the lifting strut movement is combined with the lifting stroke of the struts, for example using an eccentric mechanism, a sufficient lifting of the seat part is ensured.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a bed and a removable seat portion disposed on its edge.

Figure 2 shows a transfer chair

Figure 2a shows the end bar as seen from the end.

Fig. 3 shows a transfer chair in one operating position.

Fig. 1 illustrates a seat part 2 according to the invention positioned on the edge of a bed 1, on which the patient lying on the bed can be easily rotated to a sitting position without raising the patient. The seat part 2 is a rectangular piece of strong fabric 20 having at both ends tubular parts 3, preferably sewn from the same fabric. In addition, at least one end of the tubular parts 3 has pulling loops 4, * · * 'which grip the seat part 2 more easily »« * Book. The spacing between the tubular channels 3 at the ends of the seat portion 2 is * adapted to the distance of the support bars 5.

25 n **. Fig. 2 illustrates a trolley chair frame comprising a lower frame 10 with wheels 11 and an upper frame 12 having support arms 5 · · '· There is a height adjustment between the lower and the upper frame by telescopically inserting frame members and adjusting pin 15 at a suitable position through the holes to lock the desired height position. t. The height adjustment can also be implemented mechanically using a long screw and nut part, using a rack and pinion, or by means of a hydraulic cylinder, for example.

At the upper end of the body 12 are sleeves 7, within which the # # * ··· _ axis leading to the support bars 5 can be rotated. Prior to the actual rods 5, an eccentric part 8 is disposed at the end of the aforesaid shaft, by means of which the center line of the rods 5 is deflected from the center line of said axis, as shown in Fig. 2a. The deflection distance can be, for example, 20 - 50 mm. At one end of the shaft passing through the sleeve 7, there are drive levers 9 which, by rotating the support rods 5, are brought in and out of each other. Suitable locking means are provided for the operating levers 9, whereby their rotation is prevented by locking at least in the position in which the rods are loosened. The transport chair will at least work with the solution described above, but a useful accessory is a push / backrest device 13 which can be connected via its lower bars 17 e.g. to the tubular shafts leading telescopically to the operating arms 9 (Fig. 2). , if the patient is sitting. directional and accessory armrests 16 are still available. A table top 14 can still be attached to the armrest bars 16.

If the push / back assembly 13 is secured to the other side of the seat portion 2, the protective plugs 6 are removed from the ends of the rods 15 and the lower rods 17 of the accessory 13 inserted into the rods 5.

Since the distance of the rods 5 may vary somewhat, an angle 18 of the fixture 13 is made a joint, which allows for a slight pivoting.

Figure 2a shows the eccentric rotation of the support bar 5 on the sleeve 7. If 20 rods 5 are rotated about half a turn counter-clockwise as shown in the example, the rod 5 will zoom out to distance a and at the same time rise to distance b. For example, distance 60-100 mm can be easily selected.

t ·· V Similarly, the ascent distance b easily becomes 60 - 100 mm. The solution provides a sufficient elevation ** '*' 25 of the seat unit 2, especially when the patient is sitting on its lowest part, allowing the patient to easily detach from the bed, chair, chairs of various heights or *. from platforms and not always having to adjust the height of the upper frame to different base heights. there.
