HEMOSTAT Filed June 5, 1943 INVENTOR.

ATTORNEY Patented Sept. 18, 1945 HEMOSTAT Oliver W. Hunn, New Philadelphia, Ohio, assignor of one-fourth to A. D. Morgan, New Philadelphia, Ohio Application June 3, 1943, Serial No. 489,526

1 Claim.

This invention aims to provide a simple means for stopping the loss of human blood by suction, especially in the case of wounds, and particularly in the case of wounds of the punctural variety.

The invention aims to supply a device of the class described in which the skin and adjoining tissue may be drawn into a circumferential groove, to effect a secure sealin by means of suction.

A further object of the invention is to offer novel means for assembling the bottom portion of the device with the body thereof.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above 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, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 shows a vertical section, a device constructed in accordance with the invention, parts remainingin elevation;

Fig. 2 is a bottom plan;

Fig. 3 is a fragmental transverse section on the line 3-3 of Fig. l.

The device forming the subject matter of this application may be of any desired shape, depending upon the place on the human body where it is to be applied, and depending upon the nature of the wound. The structure may be made of plastic, if preferred.

In carrying out the invention, there is provided a hollow, closed body I, hown as being of circular cross section, but not necessarily so. The body I has a top 2, below which islocated a suction chamber 3.

Mounted on the top 2, or elsewhere, is a means 4 whereby suction may be created in the chamber 3, the aforesaid means preferably comprising an inwardly closing check valve 5.

The bottom of the body is marked by the numeral 6, and is equipped with an upstanding, tapered flange I, which aids in promoting a secure connection between the bottom 6 and the body I.

The bottom 6 is provided with a thickened, depending marginal portion 50 carrying an outer annular flange 8 which aids in the connection of the body 6 to the bottom I. The marginal portion 50 has, also, an inner annular flange 9.

The outer annular flange 8 and the inner annular flange 9 define a circumferential groove l0 and communication is established between the chamber 3 and the groove ID by means of a plurality of apertures ll, located in the bottom 6, the material intervening between the apertures ll forming connectors l2 which aid in holding the parts in the assembled relation shown in Fig. 1. a

The adjacent or inner walls I4 of the flanges 8 and 9, which define the groove l0, converge away from the lower end of the body, to promote the drawing of skin and adjacent tissue into the groove l0 and into sealing relation to the openings or apertures ll.

The construction is such that should some of the apertures l I be sealed, as aforesaid, the other apertures will remain open until suction continues long enough to cause the skin and adjacent tissue to close them.

The bottom 6 has a thickened, depending, marginal portion, including the walls of the groove l9 and the apertures H. The apertures II, at their lower ends, terminate below the bottom 6 and, therefore, due to the relative shallowness of the groove I0, the skin and adjoining tissue will not be distorted unduly, as they are drawn into the groove.

The bottom 6 is spaced from the lower ends of the flanges 8 and 9, to form a compartment IS, in which is located a wound dressing [6, surrounded by an annular suction area represented by the lower, wider end of the groove I 0.

The construction of the device is such that the flow of blood will be stopped by a small amount of suction. Skin is drawn into the groove I0, and, at the same time, suction serves to impress the device strongly upon th body of the patient, about the wound.

Owing to the fact that the thickened marginal portion 50 is provided, the bottom 6 may be thin, and the compartment which receives the dressing It may have a maximum capacity: the part 50 reinforces the device, to receive the openings II, and those openings may be of considerable length.

What is claimed is:

In a hemostat, a hollow, closed body having a bottom and a top definin an internal suction chamber, the body being provided at its lower end with a thickened, depending marginal portion having inner and outer annular flanges defining a circumferential groove, and means carried by the body for exhausting air from the chamber, the

walls of the grooves converging away from the lower end of the body, to promote the drawing of skin and adjacent tissue into the groove, the thickened, depending marginal portion of the bottom being provided with a plurality of apertures spaced circumferentially of the body, and establishing communication between the suction chamber and the groove,,the apertures constituting means for drawing the skin and adjacent tissue into sealing relation to the apertures, and the 10
