Summary of Practice3.1 These specifications outline considerations when choosing equipment to be used in the medical-legal examination of sexualassaults. The types of equipment listed should be included in any examination facility. Consideration
8、s for choosing a variation oroptional equipment are also given.4. Instrumentation and Supplies4.1 The following instrumentation should be available at examining facilities where sexual assault cases are received:4.1.1 SpeculumThe speculum is used to view the vaginal walls and cervix. Clear plastic d
9、isposable specula are preferredbecause they allow the examiner to see through them and visualize the vaginal walls. Metal specula do not allow this visibilityand also may reflect light when taking photographs. Speculum illuminators which attach to the handle should be considered as anaid (as they as
10、sist) in visualizing the vaginal walls and cervical area.4.1.2 ColposcopeThe colposcope is used to magnify and provide increased visibility, especially in the vaginal area wherestructures include many folds and grooves of tissue. The examiner must deliberately examine each structure to determine the
11、presence or absence of injury or foreign material, or both. The use of colposcopy has been shown to be critical in both pediatricand adult sexual assault examinations.4.1.2.1 There are several varieties of colposcopes manufactured and each program should review numerous types to ascertainthe best in
12、strument for their facility in view of existing equipment and physical layout of the examination environment.1 This practice is under the jurisdiction of ASTM Committee E30 on Forensic Sciences and is the direct responsibility of Subcommittee E30.01 on Criminalistics.Current edition approved June 1,

16、r Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United States14.1.2.2 The colposcope should have photographic or video capability, as well as print capacity. The photographic or videocapability should be of sufficient resolution to adequately record and document the detail observed in
17、 the examination.(1) Appropriate film digital storage media, and other supplies necessary for the type of photographic instrument must also bemaintained.(2) Cameras incapable of close-up photography, disposable cameras, or cameras, or a combination thereof, that produce“instant” photographs are gene

The ultraviolet light (Woods lamp) is most often used and is considered basic e
19、quipmentin a sexual assault physical examination.4.1.3.1 Recently, alternate Alternate light sources specifically designed for use in criminal investigation activities have beendeveloped and have which have the capability of illuminating surfaces under variable wavelength settings which can help inl
20、ocating a greater variety of stains and are valuable in locating subclinical bruising and establishing patterns of injury.4.1.4 AnoscopeWhen the examiner needs more than an external examination of the anorectal area, a clear plastic disposableanoscope should be available.4.1.5 Otoscope and Opthalmos
21、copeOphthalmoscopeThese instruments are useful to determine whether injury to the ear(s)or eye(s), or both, have occurred.4.1.5.1 Disposable shields should be used to prevent cross-contamination.4.1.5.2 The otoscope may also be helpful in examining other cavities, such as the oropharynx.4.1.6 Micros
22、copeLocal evidentiary procedures may call for an examiner to observe wet mount slides prepared from a swabto determine and record the presence of motile spermatozoa. An appropriate light microscope can be used for this purpose by aqualified examiner.4.1.6.1 A variety of photographicimaging attachmen
23、ts are available for microscopes and should be considered when procuringthe instrumentation.4.1.7 Swab DryerTo reduce degradation of samples, the examination area should contain equipment necessary to allowadequate air drying of wet or moist evidence items prior to packaging. Swab dryers are availab
24、le commercially or can be built (noheating element should be present) to the specifications of an individual examination setting.4.1.8 Examination LightThe best quality examination light available should be obtained, preferably with a halogen lightsource.4.1.9 Overhead LightingOverhead lights such a
25、s “daylight” fluorescent bulbs that give good skin tone illumination should beused, for improved observation as well as accurate photography.4.1.10 ScaleA balance beam scale should be available to accurately measure the height and weight of the examinee.4.1.11 Trays and TablesCounter space, trays an
26、d tables should be adequate and at proper height to facilitate using equipmentduring examinations. These surfaces should meet hospital standards for cleanliness.4.1.12 Other InstrumentsStethoscope, sphygmomanometer, thermometer, and surface measuring devices should be easilyavailable.4.2 SuppliesIn
27、addition to those supplies included with the instrumentation described above in 4.1, disposable supplies listedin Table 1 should be available during sexual assault examinations.4.2.1 A list of medical equipment and supplies is provided in Table 1.TABLE 1 Medical Equipment and SuppliesMedical Equipme
