EUGENE mums/N W INVENTOR Patented May 4, 1937 UNITED STATEE PATENT OFFICE 2 Claims.
This invention relates to devices for taking the blood pressure of a person.
The principal object of this invention is to provide a device having a relatively short casing for containing an inflatable rubber bag and a securing means for adjusting and holding the casing when using the same for taking the blood pressure of a person.
A further object of the invention is to provide a locking means for holding the casing when under tension.
A still further object is to provide a device of this kind which is easily and quickly manipulated in applying it to its use.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:-
Figure 1 is a plan view of the basal part of the locking means.
Figure 2 is a plan view of the top portion of the locking device.
Figure 3 is an enlarged and partial plan View of the assembled locking parts of the device.
Figure 4 is an enlarged cross section taken on line L-d of Figure 3.
Figure 5 shows a cross section of the device showing the manner in which the free end of the casing is inserted in the locking means.
' Figure 6 is a cross section showing the locking means in a locked position.
Referring to the drawing, by characters of reference, the numeral It) designates the basal part of the locking means, which consists of two bars I l and I2 spaced apart and parallel to each other providing an opening l3 between them and provided with a flattened connecting portion l4 and i5 formed on both ends. These bars ll and i2 each have a flat lower surface. Both connecting portions have been provided with central openings l6 and I1 respectively, through which pass rivets l8 used in securing the top part I9 which consists of a bar having a concave portion on the lower side to fit a convex part of the bar I2. The bar 20 is provided with inturned ends 2| and 22, which are each provided with a central opening through which the rivets l8 function when the device is assembled as shown in Figure 3. The top part [9 is thereby hinged to the rivets l8 and may be opened as shown in Figure 5 or may be closed as shown in Figures 4: and 6.
By referring to Figure 5 it will be seen that an end 23 of a casing is permanently secured to the bar i i by sewing or other suitable means. In manipulating the device the free end 24 of the casing 25 is threaded through the opening l3 and carried over the opened top portion l9, then carried back through the opening i3 and under the bar I2, and above the looped portion -of the casing 25.
By referring to Figure 6 it will be seen that by pressing downwardly on the top portion I9, the
free end 24 of the casing 25 will be compressed between the concave part of the top portion l9 and the upper convex part of the bar l2 thereby tightening the loop portion of the casing 25 as well as holding the free end 24 gripped between the bar !2 and the looped portion of the casing 25, thereby providing a dual securing means.
In this position the locking means is positively locked as any tension in the casing 25 will tend to pull the casing 25 out of the locking means, thereby increasing the holding means by added friction between the upper portion l9 and the bar 12.
While the drawing does not show an inflatable bag within the casing 25 it is understood that an ordinary rubber inflatable bag is used. If desired to take the pressure without the use of a registering device an elastic band may be supplemented for the casing 25.
The ordinary apparatus for taking blood pressure provides a long casing carrying an inflatable bag without any locking means and in order to use the same the free end is wrapped many times around the persons arm to obtain the necessary friction which holds the casing in place.
What I claim is:-
1. In a device for taking blood pressure, a relatively short inflatable casing, in combination with a locking means comprising a basal part consisting of two parts spaced apart and parallel to each other and having flat lower surfaces, one of said parts having a convex upper surface, a top portion provided with inturned ends and said ends hinged to said basal part and said top portion provided with a concave portion on its under side in order to fit over said convex basal part, substantially as described for the purpose set forth.
2. In a device for taking blood pressure, a relatively short inflatable casing, in combination with under side in order to fit over said convex basal part thereby providing a dual means for securing the casing when in a locked position as well as shortening the looped portion of the casing in swinging the hinged top portion downwardly.
