SPHYGMOMANOMETER.

Specification of Letters Patent.

Patented nee. r7, 1918.

Application filed February 6, 1917. Serial No. 146,894.

To all whom it may concern:

Be it known that I, CLEMENS B. NAGEL- MAN, a. citizen of the United States of America, and resident of Carneyville, in the county of Sheridan and State of WVyoming, have invented certain new and useful Imin Sphygmomanometers, of which the following is a specification.

This invention relates to sphygmomanometers and has for its object the provision of novel means for increasing or diminishing pressure for controlling the circulation of blood in arteries, the said invention having for its further object, the provision of novel means whereby an instrument of the type mentioned may be produced having safe portability as one of its advantages and furthermore, having provision for permit ting such portability without necessarily dismantling or dismounting the parts of the apparatus employed.

A further object of this invention is to provide compression devices whereby the limb encircling band may be adjusted to increase or diminish the pressure, the said means being effective to allow a very gradual change in the tension, thus making it minutely susceptible to pressure of the blood.

A still further object of this invention is to provide means for rendering the instrument of utility in a wide range of pressure, as will presently appear.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in perspective of an apparatus embodying the invention;

Fig. 2 illustrates a top plan view of the compression member;

Fig. 3 illustrates a perspective view of a fragment of the means for providing compression; and

Fig. 4- illustrates a perspective View of a fragment of the limb encircling member.

In these drawings 6 denotes a flexible band adapted to encircle the limb and having a pocket 7 for containing an air bag 8 which air bag is to beinflated to a greater or less extent, according to the requirements in practice. The ends of the flexible band are connected to a buckle or coupling 9 of such construction, as to afford an adjustment whereby the said band can be made to fit different people and in order to increase or diininish the pressure of the band a flexible strip 9 has its ends 10 and 11 secured to the flexible band 6, and a turning key 12 has a slot 13 through which the said flexible strip projects, so that when the key is rotated, the flexible strip is wound or unwound to increase or diminish the said pressure. The inflatable bag 8 has a coupling 12 with a branch 13, the said branch having a tubular extension 1% through which air may be blown for inflating the bag, and the air may be retained by the clamp 15 engaging the said tubular extension.

The coupling 12 is in communication with the rubber tube 16 and the rubber tube is controlled by a clamp 17 when desired, as said clamp will permit the escape of air, but when the apparatus is to be used, the clamp 17 must of course be removed so that the air compressed in the bag will find its way to the tube to aflect mercury which is held by the tube and influenced by the pressure of the air as the compression member is manipulated. The tube 16 is U-shaped and its outer end is in communication with a glass tube 18, the said glass tube and rubber tube being supported by the clip 19 and chain 20 which latter is attached to the buckle or couplin 9. A nipple 21 is attached to the glass tube and it may be closed by the clamp 22. The glass tube has graduations 23 and the rubber tube has graduations 2%, and the v glass tube may be adjusted so that the graduations thereof have certain relation to those of the rubber tube, and preferably the glass tube is graduated from O to 150 mm. Very rarely, pressure over 150 has to be registered, but if it is desired to register pressure between 150 and 250, it can be accomplished by adjusting the zero mark on the rubber tube opposite the zero mark on the glass tube. It then, the glass tube is extended farther into the rubber tube, the mercury will stand at the zero mark in the glass tube 4 exactly opposite the zero mark on the rubber tube, after which the inner end of the rubber tube is lowered, so that its graduation numbered 100 is opposite the zero mark on the glass tube and the pressure required to obliterate pulsations is read otf the' glass tube and 100 is added to it. By re'asen of the adj ustabilityof this-deviee,erhereferegiits utility and range of reading are practically without limit Whereas its portability and durability will, it is thought, commend itself to users of these devices and thoseski'lledim the art.

I claim- In a sphyglnomanometer, a limb encircling member, an inflatable bag. secured thereto, a key carried by the limb encircling member for tightening the same, a gradu- .at1l '"tube suspended from the limbencircling member, a rubber tube c0mmun1cat- 15 CLEMENS NAGELMAN.

Copies of this patent'may be obtainedfor five cents each, by addressing the Commissioner'oif Yatents, Washington; DJG.
