Abstract
Abstract Hemostatic apparatus is disclosed for operations on the head of a human being, more particularly for scalp grafts. The apparatus includes a frame of plate form provided with a strap fastener for attachment on the head of a patient, the plate being rectangular with an opening therein. Mounted on the plate is a flexible tube of loop form encircling the opening and adapted for being pressurized to exert the necessary pressure on the patient''s head to render it free of blood in the region of the opening in the plate whereby scalp grafts or the like can be performed within the field of the opening in the plate without bleeding.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
96 words
Hemostatic apparatus for operations on the head of a human patient said frame having an opening, comprising an elongated frame with means for mounting the frame on the head of a patient, inflatable compression means supported on the frame and surrounding said opening for contacting the patient''s head to delimit a predetermined area on the patient''s head, and means for applying pressure to said inflatable means to pressurize the same and stop the flow of blood in said predetermined area, said opening in said frame providing access to the predetermined area and defining an operative field.
Claim 2
Dependent Claim
96 words
Hemostatic apparatus for operations on the head of a human patient said frame having an opening, comprising an elongated frame with means for mounting the frame on the head of a patient, inflatable compression means supported on the frame and surrounding said opening for contacting the patient''s head to delimit a predetermined area on the patient''s head, and means for applying pressure to said inflatable means to pressurize the same and stop the flow of blood in said predetermined area, said opening in said frame providing access to the predetermined area and defining an operative field.
Claim 3
Dependent Claim
38 words
Hemostatic apparatus as claimed in claim 1, wherein said frame comprises a plate with said opening defining the operative field, said inflatable compression means comprising a pneumatic closed circuit member surrounding said opening to exert the necessary pressure.
Claim 4
Dependent Claim
21 words
Hemostatic apparatus as claimed in claim 2, wherein said plate has a slightly concave surface in two directions facing the head.
Claim 5
Dependent Claim
21 words
Hemostatic apparatus as claimed in claim 3, wherein said pneumatic member comprises a flat, flexible tube mounted at said concave surface.
Claim 6
Dependent Claim
50 words
Hemostatic apparatus as claimed in claim 1, wherein said means for mounting the frame on the head of the patient comprises a semi-rigid strap in two parts, and means on one part engaging the other part to effect adjustment of tighTness of the frame on the head of the patient.
Claim 7
Dependent Claim
38 words
Hemostatic apparatus as claimed in claim 5, wherein said means for mounting the frame on the head of the patient further comprises a supple head band connected to said strap to partially encircle the head of the patient.
Claim 8
Dependent Claim
56 words
Hemostatic apparatus as claimed in claim 5, wherein said means to effect adjustment of the tightness of the frame on the head of the patient comprises a screw-jack mounted on the free end of said one part of the strap engageable in notches provided in the free end of the other part of the strap part.
Claim 9
Dependent Claim
17 words
Hemostatic apparatus as claimed in claim 2 comprising means coupled to said inner tube for inflation thereof.
Claim 10
Dependent Claim
18 words
Hemostatic apparatus as claimed in claim 8, wherein said means for inflation is a manual operation pumping bulb.
Claim 11
Dependent Claim
21 words
Hemostatic apparatus as claimed in claim 9, wherein said means for inflation further comprises a manometer coupled to said pumping bulb.
Claim 12
Dependent Claim
18 words
Hemostatic apparatus as claimed in claim 2, wherein said frame and said opening are of generally rectangular outline.
Claim 13
Independent Claim
47 words
A method of effecting hemostasia on the head of a human being to effect operation in a given area thereof without bleeding, said method comprising applying pressure in an annular region surrounding said given area greater than the arterial pressure to interrupt blood flow into said area.
Claim 14
Independent Claim
47 words
A method of effecting hemostasia on the head of a human being to effect operation in a given area thereof without bleeding, said method comprising applying pressure in an annular region surrounding said given area greater than the arterial pressure to interrupt blood flow into said area.
Claim 15
Dependent Claim
35 words
Hemostatic apparatus as claimed in claim 2 wherein said plate is constituted of a lightweight metal having elasticity in bending to enable the plate to conform to the shape of the head of the patient.
