Description:

This invention relates to a sphygmomanometer cuff or band, and has for the primary object the provision of a device-of this character which may be easily and quickly applied and removed from a limb of a person and easily adjusted to fit limbs of different sizes and is so constructed as to permit the inflation pouch of the sphygmomanometer to be inspected or tobe removed for repair or to be substituted by another pouch should need occur therefor. With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully 1. described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a cuff or band constructed in accordance with my invention and showing the same applied to a limb of a person.

Figure 2 is a plan view, partly in section, showing the cuff or band prior to being applied.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a sectional view taken on the line 5-5 of Figure 2.

Referring in detail to the drawings, the numeral 5 indicates as an entirety the band or cuff, primarily consisting of elongated fabric layers 6 and 7 arranged in superimposed relation. The width and length of the layer 6 are greater than the width and length of the layer 7 and the longitudinal edges of the layer 6 are folded upon themselves and over the longitudinal edges of the layer 1, as clearly shown in Figure 5. The folded portions indicated by the character 8 of the layer 6 act as reinforcements for the cuff or band and are stitched to the layer 7, as shown at 9, 10, II, 12 and 13.

By referring to Figure 2 it will be seen that the stitching 9 extends longitudinally of the cuff or band while the stitching 10 extends transversely of the band or cuff for a limited distance. The stitching II extends between the stitches 10.

Eyelets 14 are secured in the outer layers of the folded portions 8 of the fabric layer 6 between the stitching 10 and 9. The opposing edges of the folded portions 8 where the eyelets are located are left free for the insertion of ends of an anchoring bar 15 into oppositely arranged eyelets 14. The anchoring bar is secured to one end of the cuff or band by a hem 16, the width of which is less than the overall width of the cuff or band, as clearly shown in Figure 2, so that the end portions of the anchoring rod may be easily inserted into and removed from opposite eyelets 14.

The stitching 13 is arranged in a substantially rectangular shaped pattern and is interrupted at one end of the cup or band to form a mouth to a compartment 17 formed between the layers 6 and 7 by said stitching 13. The layers 6 and I are also stitched transversely, as shown at 18. The purpose of the compartment 1, is to receive an inflatable pouch 19 of a sphygmomanometer of a conventional construction (not shown). The inflatable pouch 19 has the usual tubes 20 and 21 connected thereto. One of the folded portions of the layer 1 is arranged to provide passages for the tubes 20 and 21 to extend through.

3 One end of the layer 6 is folded over and stitched to form a hem 22. through which extends an elongated rigid loop shaped member 23 equipped with a finger piece 24.

A closure flap 25 is provided for the mouth of Sthe compartment 17 and is secured to the inner face of either the layer 6 or 7 and is adapted to have its free end tucked into the compartment after the insertion of the inflatable pouch to close the mouth, and to prevent the pouch from bulgio ing out of the compartment by way of the mouth when under inflation.

To apply the cuff or band to a limb of a person as shown in Figure 1, the end of the cuff or band carrying the anchoring rod 15 is passed through :;, the loop-shaped member 23 in such manner as to arrange the eyelets 14 outermost. By grasping the finger piece 24 in one hand and pulling upon the end of the band or cuff carrying the anchoring rod, said band or cuff may be drawn as tightly as desired about the limb. The ends of the anchoring rod 15 are then passed through opposite eyelets firmly securing the band or cuff in applied position. The pouch is then inflated as usual to stop the flow of the blood through arteries of the limb. This means of applying and securing the cuff or band in position on the limb will permit the cuff or band to be easily and quickly adjusted to a desired tautness on limbs of different sizes. As soon as the ends of the anchoring rod are removed from the eyelets, sufficient slack may be brought into the cuff or band so that it may be slipped off of the limb without passing the anchoring rod through the loop shaped member 23. However, when the anchoring rod is freed as specified, it canbe easily passed through the loop shaped member 23, allowing the device to assume a flattened out position, as shown in Figure 2.

Any time it is necessary to inspect, repair or replace the pouch 19, the pouch in use can be easily passed through the mouth of the compartment 17 when in a deflated condition. The closure flap 25 may be easily brought into a position of opening the mouth as suggested in dotted lines in Figure 3.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the inven- 1 tion as claimed.

Having thus described my invention, what I claim is: 1. In a sphygmomanometer cuff, an elongated flexible double wall strip having a compartment 2 in a portion thereof to receive an inflatable pouch, a loop shaped member at one end of said strip to permit the other end thereof to pass therethrough for wrapping the strip about a person's limb, eyelets arranged on the strip, and . an anchoring rod secured to the last-named end of the strip for insertion in the eyelets for anchoring said strip in wrapped position about the limb.

2. In a sphygmomanometer cuff, an elongated ;o double wall fabric strip having a compartment in a portion thereof, said compartment provided with a mouth to permit placing in the compartment an inflatable pouch, a closure flap for the mouth, a loop shaped member secured to one :;, end of said strip to permit the other end thereof to be passed therethrough for wrapping the strip about a person's limb, an anchoring rod secured to the other end of the strip, and eyelets arranged on the strip adjacent the edges there- 1o of and in opposed relation to each other for receiving the anchoring rod for adjustably securing the strip in a wrapped position on the limb.

3. In a sphygmomanometer cuff, an elongated double wall fabric strip having a compartment in a portion thereof, said compartment provided with a mouth to permit placing in the compartment an inflatable pouch, a closure flap for the mouth, a loop shaped member secured to one end of said strip to permit the other end thereL0 of to be passed therethrough for wrapping the strip about a person's limb, an anchoring rod secured to the other end of the strip, eyelets arranged on the strip adjacent the edges thereof and in opposed relation to each other for recelv5i ing the anchoring rod for adjustably securing the strip in a wrapped position on the limb, and a finger piece carried by the loop shaped member.

4. In a sphygmomanometer cuff, an elongated o double wall strip composed of layers of fabric arranged in superimposed relation and stitched together having edges of one layer folded upon itself and over edges of the other layer for reinforcing the strip throughout its length, eyelets ; secured in the folded portions of one of the layers of the strip, stitching securing the layers of fabric on the strip together to form a compartment having a mouth, a closure flap for the mouth, said compartment adapted to receive an inflatable pouch having tubes, one of the folded portions of one of the layers having openings to permit the tubes to extend therethrough, a loop shaped member secured to one end of the strip and provided with a finger piece, and an anchoring bar secured to the other end of the strip and adapted to be passed through the loop and inserted in the eyelets for adjustably securing the strip in wrapped form about a limb of a person.
