Syringes history


Syringes history
Syringe is  "an instrument such as a hypodermic syringe,
or a rubber ball with a slender nozzle for use in drawing or injecting fluids, cleansing wounds,
etc." In Roman times,  nasal syringes had an other metal case with a tow or flax plunger. In the 17th, English syringes were made from pewter or silver. The barrel and head were 20 cm long. reccomment to rectal ro vaginal use.
John Moyle (1693) used wine in an ear syringe and Dominique Anel developed a suction syringe
to used for infected wounds. Larger syringes were used for irrigation. Almost all structures,
including the lachrymal duct, were cannulated. In the mid of 19th. century a small syringe was
developed. It had a screw arrangement, which permitted the release of a single drop.
The first syringe patents by John and Frederick Weiss were taken out in 1824 and 1851
respectively. A stomach pump was patented by John Read (1760–1847). Read’s enema syringe
was made of brass and had ivory attachments.


19th.century novels suggest that the enema was taking a place in the lives of the healthy as
well as the ill. There was an ingenious and wide variety of apparatus. Maw’s catalogue of
1868 offered 39 varieties of equipment for colonic irrigation, made of every material, and
some were extensively decorated. The smaller ones were made of brass, pewter, or glass,
with a rubber or twine bound plunger. A silk covered rubber tube was supplied with an ivory
plug for rectal irrigation or a rubber covered brass tube for the vagina. Larger varieties had
an independent reservoir and worked as a brass pump. One introduced in 1830 was sold as
“Maw’s Domestic Medical Machine”.
