Section I. TRAYS
4-1.
TREATMENT TRAYS AND SETS
a. General. The basic diagnostic and therapeutic trays that are commonly used
are illustrated in figures 4-4 through 4-19. The legends on these figures indicate how
the tray is used as well as list the items displayed. Each medical facility will vary the
setups to meet the needs and policies of the individual facility. Some of the common
items used on treatment trays and sets are described in the following paragraphs.
(1) Towels. In most procedures, towels are used as a drape. The number
of towels depends upon the procedure, so they are packaged separately and added as
needed.
(2)
Towel clips. Towel clips are necessary to keep the towels in place.
(3) Sponges. Sponges are a sterile surgical dressing of absorbent material
for wiping or absorbing blood or other fluids during an operation. Sponges are an
essential on almost every tray. The number of sponges is usually standardized in a
medical facility.
(4) Sponge forceps. Forceps are instruments, similar to pincers or tongs,
for seizing and holding objects, especially in surgical operations. Sponge forceps,
often called "sponge stick" are used to hold sponges and used as a swab.
(5) Solution cup. The container for the antiseptic is a solution cup and is
made of different material than a medicine glass.
(6) Medicine glass. A one ounce glass used for a number of fluids such as
liquid medication, germicides, saline, and so forth. It is included in most trays.
(7) Syringes. Whenever a local anesthetic (a drug used to "deaden" a
particular area) is necessary, a syringe is needed. Syringes are wrapped unassembled
to assure contact of all surfaces with steam or gas during the process of sterilization.
(8) Needles. When reusable needles are a component of a tray, three sizes
of needles are usually included in a tray. Needles are placed in a sponge. See figures
4-1, 4-2, and 4-3.
