From 1834 to 1975, more than 60 breast pumps were patented, the majority in the period from 1860 to 1920.[168]

_The Decline of Cupping_

Cupping died out in America in the early twentieth century, but its disappearance was gradual and scarcely noticed. Some of the most complex of cupping devices were invented in a period when most physicians regarded cupping as ineffectual. Patents for cupping devices continued to be issued as late as 1916 when Joel A. Maxam of Idaho Springs, Colorado, patented a motorized pump, which by means of various sizes of cups, could subject a part of the patient's body to either a prolonged suction or a prolonged compression.[169] One of America's last advocates of bloodletting, Heinrich Stern, writing in 1915, also advocated the use of an electrical suction pump to evacuate cups. With an electric motor, he declared, one could prolong hyperemia for 15, 30, or more minutes.

Stern also invented a theory to account for the therapeutic effects of his inventions, namely, the theory of phlebostasis. Instead of pumping air out of a device, Stern pumped air into a device, for the same purpose of removing a portion of blood from the general circulation. His ”phlebostate,” manufactured by Kny-Scheerer of New York, was quite similar to a sphygmomanometer. It consisted of a set of cuffs that fit about the thighs, rubber tubes, a manometer, and a suction bulb or an electric force pump. For stubborn cases, such as migraine headaches, Stern recommended using the cuffs for 30 minutes or more. To facilitate the application of the cuffs, Stern invented a ”phlebostasis chair,” one of the most complex ”cupping” devices ever made. Like an electric chair, the phlebostasis chair was supplied with cuffs for both arms and legs. Air was pumped into the cuffs by means of an electric motor. According to Stern, compression of the upper segment of both arms withheld 300 cc of blood from circulation, while compression of the thighs withheld as much as 600 cc.[170]

In addition to these sophisticated devices, simple cupping, especially dry cupping, continued well into the 1930s. Although cupping was no longer generally recommended by physicians, most surgical companies advertised cups, scarificators, and cupping sets in the 1920s and even the 1930s. The last bastions of cupping in the United States were the immigrant sections of large cities. In the lower East Side of New York, in particular, cupping was still flouris.h.i.+ng in the 1920s. By then cupping was no longer performed by the physician, but had been relegated back to the lowly barber, who advertised in his shop window, ”Cups for Colds.”[171]

Leeching

_Leeches_

The word ”leech” derives from the Anglo-Saxon _loece_, ”to heal.” Thus, the Anglo-Saxon physician was called a ”leech” and his textbook of therapeutic methods a ”leechdom.” The animal itself was already known to the ancients under its Latin name _hirudino_. It appears, however, that the introduction of leeches into Western medicine came somewhat later than that of phlebotomy or cupping, for Hippocrates made no mention of them.

The earliest references to the use of leeches in medicine are found in Nicander of Colophon (2nd century B.C.) and in Themison (1st century B.C.). Thereafter they were mentioned by most Greek, Roman, and Arabic medical writers.[172]

The leech is a fresh-water parasitic invertebrate belonging to the Phylum Annelida. On one end of its worm-like body is a large sucker by which the animal fastens itself to the ground, and at the other end is a smaller sucker, in the middle of which is a chitinous mouth that makes a triangular puncture. As items of _materia medica_, leeches were described in dispensatories, or compilations of medicaments, and sold by apothecaries, both to physicians and directly to patients. The species most commonly used for bleeding was _Hirudo medicinalis_, indigenous to the streams and swamps of Central and Northern Europe, and known in commerce as the Swedish or German leech. It was 50-75 mm long, with a dull olive green back and four yellow longitudinal lines, the central two broken with black. Somewhat less popular was the Hungarian leech, indigenous to Southern Europe. In addition, there was an American species of leech, _Hirudo decora_, which was gathered princ.i.p.ally from the lower Delaware River, but, since it drew much less blood than the Swedish leech, it was regarded as greatly inferior.[173] Most American physicians imported their leeches. In the late nineteenth century, one could buy Swedish leeches for $5.00 per hundred.[174]

Leeches were gathered in the spring of the year either by means of a pole net, or, more primitively, by wading into the water and allowing the leeches to fasten themselves onto the legs. Sometimes horses and cattle were driven into the water to serve as bait for the leeches.[175] (Figure 19.)

Leeching, like other forms of bloodletting, enjoyed a revival in the early nineteenth century, particularly in France, where the doctrines of heroic medicine preached by Broussais[176] led to an increase of leech usage from about 3 million in 1824 to 41.5 million in 1833.[177] Leechers, although not as high in status as professional cuppers, practiced in many large cities, and numerous tracts were written on the care and breeding of leeches. ”Leech farms” were unable to increase the leech supply to meet the rising demand, and most leechers complained of the scarcity and great expense of the little animals.[178]

Leeching and cupping each had their advocates. The major advantage of the leech over the cup was that the leech could be employed on almost any part of the anatomy, including around the eyes, in the mouth, the a.n.u.s, and the v.a.g.i.n.a. In fact, leeching the internal membranes enjoyed quite a vogue in the early nineteenth century. Leeches were applied to the larynx and the trachea for bronchitis and laryngitis and for relieving the cough of phthisis. For inflammations of the conjunctiva (the membrane lining the eyelids) they were applied to the nasal membrances of the adjacent nostril, and for inflammations of the ear they were applied to the meatus of the ear and behind the ear. The French popularized the practice of leeching the a.n.u.s to treat inflammations of the mucous membranes of the bowel. To prevent leeches from getting lost in the body cavities, Jonathan Osborne, a British physician, recommended in 1833 that a thread should be pa.s.sed through the leech's tail. In addition, he invented a device, which he called a ”polytome,” specifically for introducing leeches into the r.e.c.t.u.m.[179] In the mid-nineteenth century, special leech tubes were widely sold for applying leeches to internal membranes.[180]

A second advantage of leeches over cupping was that leeches could extract blood more readily. Not only was dexterity not required in order to apply a leech, but also it was soon noticed that leech bites continued to bleed even after the leech let go, while scarificator incisions often coagulated before any blood was obtained. In 1884 it was shown by John Berry Haycroft, a Birmingham chemist, that this phenomenon was due to an anti-coagulant, now called ”hirudin,” that the leech injected into the blood.[181]

To apply a leech, the animal was first dried with a bit of linen, and the skin of the patient was prepared by was.h.i.+ng with warm water and then shaving. To direct it to the right spot, the leech was often placed in a small wine gla.s.s that was inverted over the area to be bitten. Since leeches were sometimes perversely unwilling to bite, they were enticed by the placement of a bit of milk or blood on the patient's skin. Small children were given one or two leeches, and adults 20 or more. Broussais employed up to 50 leeches at one time.[182] The leech was usually allowed to drop off of its own accord when it had satiated itself, which took about an hour. Sometimes the tail of the leech was cut off so that it would continue to suck. Once used, leeches could not be reused for several months unless they were made to disgorge their meal by dropping them in salt water or weak vinegar. A healthy leech drew one or two fluid drachms of blood, and as much would flow after the leech had dropped off. Thus a good Swedish leech could remove about an ounce of blood. This quant.i.ty could be increased by employing a cupping gla.s.s over the bite.[183]

Leeches were kept in a gla.s.s container of water covered with gauze or muslin and placed in a cool, dark room. The water had to be changed frequently, as much as every other day in summer. Pebbles or moss were placed in the bottom of the vessel to aid the leech in removing the slimy epidermis that it shed every four or five days. In the nineteenth century leeches were often sold in drug stores from large, elegant containers with perforated caps. Actually, only the day's supply of the pharmacist's leeches was kept in the attractive storefront jars; the rest were kept out of sight. While most leech jars were simple white crockery pieces with ”leeches” lettered in black on the front, some leech jars were over two feet tall and decorated with elegant floral and scroll work. Among the most ornate leech jars were those made in Staffords.h.i.+re, England.[184]

_Artificial Leeches_

One of the characteristics of nineteenth-century technology was the attempt to replace natural materials and processes by imitations and mechanisms. Considering the properties of the natural leech, it is no wonder that very early in the nineteenth century inventors began to seek a mechanical subst.i.tute. The disadvantages of the leech were many. Wrote one inventor of an artificial leech:

In the first place the appearance of the animal is repulsive and disgusting, and delicate and sensitive persons find it difficult to overcome their repugnance to contact with the cold and slimy reptile.

This is especially the case when it is a question of their application about or within the mouth. Then again, their disposition to crawl into cavities or pa.s.sages results sometimes in very annoying accidents. Another source of annoyance is that they are often unwilling to bite--the patience of all concerned being exhausted in fruitless efforts to induce them to take hold.

The expense, too, of a considerable number is by no means trifling.[185]
