" Application September 16, 1944, Serial No. 554,346

relates to a sph-ygmomanometer cuff, air-inflated pressure tourniquet or the like, and to a method of forming and making the same.

The usual open-type sphygmomanometer fabric cuff, including an inflatable rubber bag disposed within the casing at one portion thereofiis se- This invention cured around the arm of the patient by a winding and wrapping operation and by tucking the end of the material under the wound portions of the cufi. Such cuffs are awkward to apply and require a considerable length of material for their construction. They do, however, have the advantage when applied, of conforming to the contour of the arm. Other known open type cuffs also require wrapping and are provided with latching means to hold the same in position for inflation of the bag. i

It is an object of the present invention to provide a flexible fabric cuff, including an inflatable rubber bag, tourniquet or the like, which can be applied with case without wrapping and winding. To that end a cuff, tourniquet or the like is provided in the form of a closed loop which has the advantage of being easily applied and removed and which when applied conforms readily to almost any shape and size of arm or limb within reasonable limits, as effectively as the open-type of cuff. n

A further object'of theinvention is to provide a method of forming and making the closed-loop cuff, tourniquet or the like from a single strip of fabric, so that the resulting cuff and casing is provided with a series of integrally formed cartridge-like pockets or loops providing means on the outer surface thereof for retaining the fastening hooks after being inserted therein.

According to the present invention, the cuff, tourniquet or the'likc is in the form of a closed loop of a sufiicientdiameter into which the patients arm or leg may be inserted readily. The cuff is thereupon closely applied about the arm or leg by gathering together the slack end portion of the loop and folding the same back upon itself over the portion closely contacting and enclosing the arm. One form of cuif is made from a single strip of material with its sides folded inwardly and the folded strip stitched crosswise along its length to provide two rows of cartridgelike pockets or loops atpopposite sides of the cuff into which'the fastening hooks can be inserted easily. The ends of the foided and stitched strip are stitched or otherwise connected together to provide a closed .or endless loop .of such size as to enclose, with some slack, arms or legs of a reasonable range of sizes. Two spaced flapssor fastens 7 ing projections, which can flex independently of each other, are located respectively at the sides of the cuff and in alignment with the pocket rows. U-shaped hooks, each of which has a leg portion adapted to fit the pockets, are respectively se- The hooks can be fastened cured to the flaps.

in staggered pockets can be adjusted to other edge of the cuff so that one edge of the can a greater length than the Fig. 1 shows a sphygmomanometer cuff attached to a patients arm with the hooks fitted in staggered pockets, thereby allowing the cuff to be adjusted to the arm shape;

Referring now to Figs. 1 to 4, one form of cuff I2 is shown. strip I3, Fig. material, 4!.

3, of fabri, twill or other flexible whereby the cuff can readily conform to dimensional variations of the pais made and illustrating how from a sup- This cuff is made from a single The strip has three ngtches I 4, i4 and j cut in each of its ends and is folded from opposite sides along lines extending from end to end and between outer notches, as illustrated at 15, and with its outer edge 16 folded under, as indicated at 11. Two-ply or tongue-shaped projections l8, 19 are thus formed of the folded strip ends, one at each side of inner'notch l4. Several spaced parallel stitchings 2B are made crosswise of the strip to provide two rows or series of cartridge-like pockets or loops 2|, one row at each side of the strip. The pockets or loops provide fastening-member receiving devices on the outer surface of the casing. The ends of the strip are brought together so that projections l8, 19 of one end are matched with projections I6, IQ of the other end, and the ends of the projections themselves are turned in and sewed together at 23 to retain U-shaped hooks or fastening members 24 by their legs 25. The projections ar again sewed at 26 parallel to sewing 23 to finally retain the hooks on the combined projections or flaps 21, Figs. 1, 2. A lug 28 on the hook leg 25 revents the hook from sliding out of the parallel sewings 23, 26. The strip ends are again stitched or otherwise secured along line 23 to provide closed-loop flexible casing 30 large enough to have any siZe limb inserted and still have slack portions or slack ends 3| which may be gathered and folded or drawn over an ungathered portion 32 to tighten the loop on the patients limb. ,By virtue of the end notches l4, the flaps 21 can flex independent ly of one another and along line 29. The hooks 24 on the flaps 21 each have an attaching leg 33 which extends outwardly and is adapted to be inserted in any of the pockets 2|.

On the inner side of the closed loop 30 an inflatable bag 34 is retained by a covering fabric 35 stitched to the fabric strip I3. This bag has hose connections 36 and 31 having, respectively, a pressure gauge 38 and a pumping bulb 39.

The patient merely inserts his arm 40 through the loop 36 to locate the cuff on the upper portion 4| thereof and adjacent the arm artery. The slack portions 3| are gathered together and folded over the ungathered portions 32 to tightly fit the cuff to the upper arm portion 4|. Since the arm may have a larger diameter at the upper edge of the cuff than at the lower edge, the hooks 24 are inserted in their in staggered relation with one another, as shown in Fig. 1. The upper hook thus lies rearwardly of the lower hook to provide an increased amount of cuff at the upper edge. Since the flaps can be separately flexed, the adjustment is made without the cuff being ruflled. Once the hooks are fitted'into the pockets, the blood pressure within the artery can'be taken. The air bulb 39 is operated to inflate the ba 34 until the fiow of blood in the artery is stopped. At this point, the pressure reading is taken from the gauge 38.

Referring now to Figs. 5, 6, a double cuff 45 is shown which is applied in the same manner that cuff I2 is applied but which is differently constructed. The cartridge-like pockets 46 are formed by stitching onto a main wide strip or web 41, as indicated at 48, separate parallel narrow strips 49 and 50. The main strip 41 is one piece throughout its entire length. An inflatable bag is retained by a covering fabric 5!" stitched to themain strip 41.

Both of the narrow strips and the main strip have sewed to their parallel edges, folded-over reinforcing tape 52.

One end of the main web has separately flexed flaps 53, 54 having hooks 55, 56 secured thereto by folding overthe flap ends and sewing them as to Figs. '7, 8, there is shown an formed from a half section of the folded strip l3 of Fig. 3. A strip I3 is cut in two after it has been folded, and the cut edge is folded over and forcing edge 65, when stitched, opposite to main pocket fold 65. Main pocket fold 66 is stitched to provide a series of cartridge-like pockets or respective rows of pockets,

. provided a method whereby loops 58 adapted to receive a U-shaped hook 69 secured to joined ends 10 of the folded strip.

This tourniquet is applied to an arm 15 in the same manner that the wide sphygmomanometer cuff is applied. The arm is inserted through closed loop 1| and slack portions 12, 13 are folded back firmly, over the remaining or ungathered portions 14 of the loop tightly about the arm, Fig. 8. Hook 59 is inserted into one of the cartridge-like pockets 58.

A narrow inflatable bag 16, having hose connections 11, 18 is secured to the inner side of the loop by covering fabric 19. The bag 16 is inflated in the usual manner to shut off the blood flow through the arm. When it is desired to reestablish circulation of the blood through the arm, air may bewithdrawn from the inflated bag 16, to the extent required. If it is desired to permit the free flow of blood, the hook 69 may be withdrawn from the pocket in which it is located and the complete release of the tourniquet effected. No unwrapping or untwisting is thus necessary to remove the tourniquet.

Referring to Figs. 9, 10, there is a tourniquet constructed similarly to the cuff 45 of Figs. 5, 6. Cartridge-like pockets 8| are formed by stitching a, narrow strip 82 upon main strip or web 83. Both of these strips have their edges reinforced with folded-over tapes 84 and 85. The stitching to provide the pockets BI is indicated at 85 and is made across the full width of the main strip83. The ends of the strip are joined at 81 with hook 88 secured thereto. Inflatable bag 89 is secured to theinner side of the main strip 83 by cloth covering 90 stitched thereto.

It should now be apparent that there has been provided a sphygmomanometer cufi, tourniquet or the like, which can be readily applied to the patients limb without having to perform a tedious wrapping or winding operation thereupon and yet fitting the limb with the exactness of the pped type of cuff.

It should also be apparent that there has been the fastening pockets are formed by a simple folding operation from a single strip.
