Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to arm bands, such as those used in hospitals to identify patients.

According to the invention, there is provided an armband comprising a band portion including a series of cam surfaces alternating with a series of stop surfaces, and a latching portion including a latching slot for receiving said band portion. , a boundary portion of the latching slot includes a displaceable latching element, and while the band-shaped portion passes through the slot in one direction, the latching element is bent to form a loop shape of the arm band. said cam surface forming said cam surface, and engagement of said latching element with any one of said stop surfaces prevents the strip from slipping out of the slot in the opposite direction. The strip can be channel-shaped and consist of a base and two side flanges.

The latching slot may be formed between an arched portion including a latching base and a leg perpendicular to the latching base and a transverse piece parallel to and spaced apart from the latching base. In the reference example, a ratchet-like protrusion is provided on the inner surface of each of the flanges, one surface of each protrusion serves as a cam surface, and the other surface serves as a stopper surface. In this configuration, the armband is provided with a latching element for cooperating with the series of projections, comprising two latching elements, and preferably this latching element comprises two latching elements. and spaced apart from the legs so that a gap is formed between each leg and the adjacent latching element for receiving one of the flanges. One or more wedge-shaped latching elements are preferred, the larger end of the wedge securing it to the rest of the armband, and the smaller end of the wedge being free to flex. It's becoming like that.

In an embodiment of the invention, the strip has holes, one side wall of each hole forming a cam surface, and the other side wall of each hole forming a stop surface.

In this configuration as well, the aperture is provided in the base, allowing the strip to be channel-shaped and consisting of a base and two side flanges. Preferably, the plane on which the lateral wall of the hole lies and the main plane of the strip-shaped portion intersect at an angle other than a right angle.

Furthermore, each latching element can fit into each hole in turn as the holes pass one way through the slot;
Each cam prevents engagement of the element-receiving hole during movement of the band in said one direction, and the stop surface prevents said element from being engaged with said element-receiving hole as the band moves in said opposite direction. It is designed to be pushed into one of the holes. Preferably, the armband is injection molded in a single piece and has a roughened surface, the roughened portion being between the strap portion and the catch portion; And that part is wider than other parts. For a better understanding of the invention and to show how it may be carried out, reference will be made, by way of example, to the accompanying drawings.

Figure 5, which is a cross-sectional view taken along the line - ■, has the same dimensions as Figure 4, but is a cross-sectional view taken along the line ■-■ of Figure 1, and Figure 6 is the same as that of Figure 3. Figure 7 is a cross-sectional view taken along the line ■-■ of Figure 3. Figure 8 is another drawing of the arm band. Figure 9 is a cross-sectional view taken along the line ■-■. FIG. 10 is a side view of the arm band in FIG. 8; FIG. 10 is a cross-sectional view taken along the line X-X in FIG. 8, showing larger dimensions; and FIG. - of Figures 9, 10 and 11 showing the formed arm band.
■It is also a large-sized cross-sectional view taken along the line.

The illustrated armband includes a band 10, a section 12 with information.
, and a latch 14 for holding the arm band in a closed loop around the wearer's arm.

The free end of the band 10 is, as explained more fully below,
The hook 14 has a conical shape 16 with a rounded end.
This makes it easy to engage the attached belt.

Between this conical part 16 and the part 12 the band 10 is connected to the base 18
and a channel section (see especially FIG. 4) having two upright side flanges 20. Each flange 2
A large number of latch teeth 24 are formed on the inner surface of 0. The gently sloping surface of each tooth faces toward the cone 16;
and the sharply sloping edge of each tooth faces towards the portion 12. This section 12 has a flat rectangular cross-section, as is clear from FIG.

This portion 12 lies between the strap 10 and the neck 26 that joins the catch 14 to the portion 12.

The hanging body 14 has a base portion 28 that is somewhat wider than the neck portion 26;
Along with this base 28 is a slot 32 for receiving the band 10.
It includes an arched portion 30 forming a .

This arched portion 30 has an upright portion 34 joined by a transverse piece 36.
It consists of

As is clear from FIG. 3, this horizontal piece 36 has a U-shape as a whole when viewed in plan, and this shape allows a horizontal bar 38 and two longitudinally extending limbs 40 to form a U-shape. It is formed. The inner surface of this rim 40 is indicated at 42 and the cross bar 38
It will be appreciated that the cross section 44 has an inclination relative to the transverse plane 44. A block 246 is provided on the lower side of the horizontal piece 36, and the end surface of this block is shown in FIG.
Indicated by line 48.

It will be appreciated that these planes are aligned with plane 42. Two latching elements 50 are integral to this block 46 and extend in front of the face 44 of the crossbar 38.

The outer surface of the latching element 50 forms an extension of the edge 48 of the block 46 and is thus vertically below the surface 42. The flat front face of block 46 is indicated at 52 in FIG. 6, and the front face of element 50 is indicated at 54.

This arm band is designed to tighten the arm band around the arm.
The smooth surface (upper surface in FIG. 7) is placed against the user's skin to form a loop. The conical portion 16 is pushed through a slot 32 surrounded by the base 28, the uprights 34 and the transverse pieces 36. As can be seen from Figures 4 and 6, the shape of this slot matches the cross-section of the strip.
When the band is pushed into the slot, the gently sloped surfaces of the teeth 24 cam the catch elements 50 inwardly and toward each other, allowing the band to pass through. Each time the tips of a pair of teeth 24 leave the locking element 50, this element snaps outwardly behind these teeth. Once the band has achieved the desired tightness around the arm, the slot 32
Cut the portion of the band 10 that protrudes from and over the neck 26 and section 12.

The engagement between the front surface of the latching element 50 and the steeply sloped surface of the tooth 24 makes it possible to prevent the band from being pulled out from the underside of the crosspiece 36. To remove the arm band, you must cut it. Information about the patient is in this part 1
It is attached to 2. The illustrated wristband is intended to be injection molded, and one side of portion 12, the outwardly facing side, is roughened to permit information to be written directly thereon. This can be obtained by sandblasting each side of the molded body. Next, the 8th ~
Referring to FIG. 11, these illustrate embodiments of the invention and are similarly numbered.

In this configuration, the base 18 is formed with a series of spaced holes 56, many of which are evenly spaced from each other, but three holes 56 adjacent to the portion 12.
are closer together than other parts.

Both ends of each side flange 20 terminate in a beveled portion 22 . Each hole 56 is surrounded by laterally spaced apart and longitudinally extending side walls 58 and lateral walls 60 and 62.

The walls 60 and 62 are sloped relative to the top and bottom surfaces of the base 18, as seen in FIG. The armband catch 1C shown in FIGS. 8-11 has a base 64 which is somewhat wider than the neck 26 and an arched portion 66 which together with this base 64 forms a slot 68 for receiving the band 10. Contains.

This arched portion 66 is formed by an upright portion 7 joined by a transverse piece 72.
0, and a block 74 molded on the lower surface of the horizontal piece 72. A centrally located rectangular hole 76 is located in the base 6.
4 and in the form of a bendable wedge 78 projects from the center of the rear transverse boundary wall of this hole 76 and slopes upwards to the block 74 .

The upper end of wedge 78 is located close to the underside of block 74. To attach the arm band around the arm, the band is formed into a loop with its smooth side (lower side in Figure 9) facing down against the user's skin.

This is illustrated diagrammatically in FIG. 10 by the dash-dotted line. The conical portion 16 includes a base 6, an upright portion 70, and a horizontal piece 72.
, and through the slot 68 surrounded by the block 74. As is clear from FIG. 11, the shape of the slot 68 matches the cross section of the strip 10. Obi 1
As the zero is forced through slot 68, wedge 78 moves away from block 74 and points downwardly, camming into aperture 76 to allow free passage of band 10.

When the hole 56 in the conical portion 16 is brought into close proximity to the wedge 78, the wedge springs into the hole.
The strip 10 is inserted into the slot 68 as shown by the arrow x in FIG.
When further pulled through, the wall 62 cams the wedge 78 downwardly out of the hole in which it resides.
Once the band has achieved the desired tightness around the arm, the portion of the band 10 that protrudes from the slot 38 and covers the neck 32 and portion 12 is cut. Attempting to loosen the band by pulling it in the direction of arrow X in FIG. 10 causes engagement between the surface 60 of the hole 56 in which the wedge 78 is seated and the underside of the wedge. Therefore, this wedge is block 7
4, this band cannot be removed without breaking this wedge 78 or tearing this band 10, as again apparent from FIG. 1st
The position shown in FIG. 0 shows the state in which the band 10 is about to be pulled back. In the reference example of the armband of FIGS. 1-7, the teeth 24 are replaced by teeth projecting upwardly from the base 18, and the elements 50 are replaced by unitary elements projecting downwardly from the crosspieces 36.

Additionally, in both illustrated embodiments, the stopper is 80 mm.
(See Figure 1). Once the protrusion of the band is cut, the cut end is pushed behind the stopper to prevent the band from becoming tighter. Instead of writing on section 12, a rectangular paper label, card, or cloth is adhered to section 12 and a clear plastic sleeve is placed over the card or paper to protect it.

The label can be backed and provided on a reel so that it can be peeled off and applied to the band.
Suitable materials for the arm band single piece described include:
There are polypropylene and polyethylene.

Nylon and rubber are also suitable materials.゜Although shown as an "arm band," there may be situations in which the item described above cannot be attached to the patient's arm.
It should be understood that these can also be attached to the patient's ankle.
