Excerpt from Covenant Mutual: Life Insurance Co; Of Saint Louis, the Oldest Life Insurance Company in the West
The great number of instruments devised for transfusion is sufficient evidence of the difficulty experienced by those who have attempted this procedure in accomplishing it.
The instrument now presented meets many of the objections that may be urged against those in more common use.
It consists of a glass receiver (No. 1), capable of holding two or three ounces, having connected with its narrow funnel point, by means of a piece of india rubber tubing two inches long (2), a silver or block tin point (3), so constructed that the narrow end, being prolonged half an inch beyond the narrow opening of the tube, serves as a guide for passing the point into the vein of the patient.
The rubber bulb (4) is designed to fit the large upper opening of the glass receiver, and the tube (5) will transmit the air from the mouth of the surgeon through the rubber bulb (4) to the surface of the blood in the glass receiver (1), so that it may be forced into the veins of the patient.
