5、igations3E 2123 Practice for the Transmittal of Evidence in SexualAssault Investigation3. Summary of Practice3.1 These specifications outline considerations when choos-ing equipment to be used in the medical-legal examination ofsexual assaults. The types of equipment listed should beincluded in any

6、examination facility. Considerations for choos-ing a variation or optional equipment are also given.4. Instrumentation and Supplies4.1 The following instrumentation should be available atexamining facilities where sexual assault cases are received:4.1.1 SpeculumThe speculum is used to view the vagin

7、alwalls and cervix. Clear plastic disposable specula are preferredbecause they allow the examiner to see through them andvisualize the vaginal walls. Metal specula do not allow thisvisibility and also may reflect light when taking photographs.Speculum illuminators which attach to the handle should b

8、econsidered as an aid (as they assist) in visualizing the vaginalwalls and cervical area.4.1.2 ColposcopeThe colposcope is used to magnify andprovide increased visibility, especially in the vaginal areawhere structures include many folds and grooves of tissue. Theexaminer must deliberately examine e

9、ach structure to deter-mine the presence or absence of injury and/or foreign material.The use of colposcopy has been shown to be critical in bothpediatric and adult sexual assault examinations.4.1.2.1 There are several varieties of colposcopes manufac-tured and each program should review numerous ty

10、pes toascertain the best instrument for their facility in view ofexisting equipment and physical layout of the examinationenvironment.4.1.2.2 The colposcope should have photographic or videocapability, as well as print capacity. The photographic or videocapability should be of sufficient resolution

11、to adequatelyrecord and document the detail observed in the examination.4.1.2.2.1 Appropriate film digital storage media, and othersupplies necessary for the type of photographic instrumentmust also be maintained.4.1.2.2.2 Cameras incapable of close-up photography, dis-posable cameras, and/or camera

12、s that produce “instant” pho-tographs are generally not of sufficient quality to warrantconsideration.4.1.3 Alternate Light SourcesAlternate light sources as-sist in the location, documentation and collection of driedstains, foreign debris, and subclinical bruising. The ultravioletlight (Woods lamp)

13、 is most often used and is considered basicequipment in a sexual assault physical examination.4.1.3.1 Recently, alternate light sources specifically de-signed for use in criminal investigation activities have beendeveloped and have the capability of illuminating surfacesunder variable wavelength set

20、amination area should contain equipment necessary to allowadequate air drying of wet or moist evidence items prior topackaging. Swab dryers are available commercially or can bebuilt (no heating element should be present) to the specifi-cations of an individual examination setting.4.1.8 Examination L
