ALFRED H. BRAECK'L EIN, 0F BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO MARGUERITE A. BRAECKLEIN, OF BALTIMORE, MARYLAND.

SURGICAL DEVICE.

Application filed May 1,

To all whom it may concern:

Be it known that I, ALFRED H. BRAEOK- LEIN, a citizen of the United States, residing at Baltimore, in the county of Baltimore City and State of Maryland, have invented new and useful Improvements in Surgical Devices, of which the following 15 a specification.

This invention relates to improvement in tourniquets.

An object of the present invention is to provide a tourniquet which is especially adapted for use in intravenous treatments in that it may be easily and instantly released without interference with the operation or'danger of the needle being accidentall withdrawn from the vein.

Anot er object of the invention is the provision of a tourniquet whereby an even pull may be made in adjusting the loop, so that an even pressure all around is exerted and folding or pinching of the flesh prevented, provision being made for taking care of such flesh as might be gathered, without inconvenience to the patient.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanyin drawings and pointed out in the appends claims.

In the drawings Figure 1 is a plan view of the invention.

Figure 2 is a central longitudinal sectional view of the same.

Figure 3 is a detail perspective view of the clamping member.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the reference character 10 indicates a flexible. member which may be formed of rubber or other suitable material. This member is arranged to provide a loop 11 and for this purpose there is utilized a clamp 12 through which the ends of the loop 11 pass.

The clamp 12 is of tubular construction being preferably rectangular in cross sec.- tion, being of suflicient transverse area to permit of the free passage of the ends of the loop. The side walls of one end of the tubular member are outwardly flared as indicated at 13 and this end of the said member is also provided with oppositely extending right angularly disposed flanges 14 1923. Serial No. 638,012.

which provide transversely aligned faces 15. The construction at this end of the tubular member permits of the formation of a substantially round loop without abruptly bending the flexible member 10, the faces 15 forming a portion of this loop as will be readily seen by reference to the dotted loop shown in Figure 1 of the drawings. Also, by this arrangement any tendency of the patients flesh to gather will be taken care of at this portion of the loop. It is to be observed however that this tendency is ractically entirely eliminated by reason 0 the fact that both ends of the loop may be simultaneously drawn through the tubular pressure is provided all around.

The side walls of the tubular member are provided with oppositely located inclined.

slots 16 and extending through these slots is a bar 17 which, as shown in Figure 2, is adapted to bite into and clam the flexible member 10 so as to resist en argement of the loop but will permit free relative movement of the flexible member and clam for the purpose of reducing the size of the cop.

To provide suflicient length for the slots 16, the tubular member is formed with an oflset 18 while the bar 17 at each end is provided with a knob or head 19. These knobs or heads act to hold the bar in place and provide means whereby the bar may be readily moved to released position and pen mit of free movement of the flexible memher in either direction.

It will be apparent from the foregoing description and accompanying drawings that the invention provides a tourniquet which may be used for any and all urposes for which such a device is adapte It is especially adapted however for intravenous treatments in that it is capable of being easily and instantly'released.

The invention is susceptible of various changes in its form, proportions and minor 100 details of construction and the right is herein reserved to make such changes as propeply fall within the scope of the appended c aims.

Having described the invention what is 105 prising a tubular member adapted to receive both ends of the loop a tiered mouth at one end of said t ubular' membei' for the passage of the flexible member, spaced flanges extending upon opposite sides of the mouth, means carried by the tubular member and engaging the flexible member to permit movement of the latter through the tubular member in one direction, but holding the flexible member against movement in an opposite direction and means whereby the holding means may be instantly released;

A tourniquetcomprising on elm" tubular member having an ontwardly fl e mouth at one end Czneeeot o, loaned member extending H ro n A member the loop emme .member extending from said mouth, outwardly disposed eurved flanges extending longitudinally upon opposite sides ofthe mouth and cooperating with the flexible member to provide a. substantially annular encircling loop and means carried by he tubular member and engaging the flexible member to permit movement of the latter through the tubular member in one direction but holding said flexible member' against movement in m opposite (in ection and means whereby the noicnng means may seleased.
