1、Designation: E 1104 98 (Reapproved 2009)Standard Specification forClinical Thermometer Probe Covers and Sheaths1This standard is issued under the fixed designation E 1104; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of

2、 last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers all single-use clinical ther-mometer probe covers and sheaths intended for use with anyclin

3、ical thermometer. Requirements are given for safety, tox-icity, handling, labeling, and physical integrity. Testing proce-dures for appropriate requirements and a glossary of terms usedwithin the standards are provided.1.2 The requirements contained herein are intended toensure adequate isolation of

4、 the patient from the temperature-measuring device. In addition, the safety and health of thepatient shall not be adversely affected. When used in accor-dance with the manufacturers instructions, the probe cover,sheath, and temperature measuring device shall remit correcttemperature readings as requ

Terminology3.1 DefinitionsThe definitions given in TerminologyE 344 shall apply to this Specification with the followingadditions:3.2 Definitions of Terms Specific to This Standard:3.2.1 measurement time, ntime required from time ofpatient contact to the time when the

7、 clinical thermometer maybe removed or read to within the stated accuracy of the clinicalthermometer.3.2.2 patient, nany human whose temperature is beingtaken.3.2.3 probe, nan assembly including the transducer that isused to position the transducer in the specific location fromwhich the temperature

8、is to be determined.3.2.4 probe covers and sheaths, ndevices provided for thepurpose of preventing biological contact between the patientand the probe or clinical thermometer.3.2.5 suitable packaging unit, nthe unit(s) of packagingfor which a specific requirement of marking and labeling islogically

9、applicable. It shall not be less than the smallest unitintended for sale by the manufacturer or distributor to the finaluser.4. Requirements4.1 GeneralClinical thermometer probe covers andsheaths represented as complying with this specification shallmeet all of the requirements specified herein.4.2

10、Product SafetySheaths and probe covers shall beconstructed to preclude sharp points and edges that could causepatient injury. Probe covers and sheaths shall be constructed insuch a way that the person using them can install and removethem without touching that portion of the probe cover or sheaththa

11、t comes in contact with the patient.4.3 Physical IntegrityThe clinical thermometer probecovers and sheaths shall be constructed and packaged so thatthe physical integrity of the probe covers and sheaths will bemaintained when applied to, used, and removed from atemperature-taking device as prescribe

12、d by the manufacturer(see 5.3).4.4 ToxicityWhen the probe covers or sheaths are used asspecified by the manufacturers, its parts intended for contactwith anatomical sites during patient use shall be nontoxic (see5.1).4.5 CompatibilityThe clinical thermometer probe coversand sheaths shall be compatib

13、le with the intended use of thetemperature-taking device (see 5.4.1).4.6 Labeling:4.6.1 Instructions shall be provided for proper usage ofclinical thermometer probe covers or sheaths.4.6.2 Suitable packaging units of the thermometer sheathsor probe covers shall bear in legible characters a designati

Susceptibility to failure of

19、probe covers or sheathsshall be determined by appropriate testing by each manufac-turer or distributor.4.6.6 Identification:4.6.6.1 In order that purchasers may identify products con-forming to all requirements of this specification, producers anddistributors may include a statement of compliance in

20、 conjunc-tion with their name and address on product labels, invoices,sales literature, etc. The following statement is suggested whensufficient space is available: “This thermometer conforms to allof the requirements established in ASTM Standard E 1104.Full responsibility for the conformance of thi

21、s product to thespecification is assumed by (name and address of producer ordistributor).”4.6.6.2 The following abbreviated statement is suggestedwhen available space on labels is insufficient: “Conforms toASTM Standard E 1104 (name and address of producer ordistributor).”4.7 Use, Operating, and Sto

Testing Procedur

23、es5.1 Significance and UseThis section describes the pro-cedures necessary to verify conformance to certain require-ments of Section 4. Procedures that can be verified byobservation are not included. The inspection and test proce-dures contained in this specification are used to determine theconform

24、ance of probe covers or sheaths to the requirements ofthis specification. Each producer or distributor representingproducts as conforming to this specification may use statisti-cally based sampling plans that are appropriate for eachparticular manufacturing process, but shall keep the essentialrecor

25、ds necessary to document the claim that all of therequirements of this specification are met.5.2 Toxicity TestTest materials intended for patient con-tact shall be in accordance with the current issue of USPBiological Test-Plastic Container, Table 1: Extract of sample insodium chloride and extract o

26、f sample in vegetable oil.35.3 Leakage TestAfter placement and removal of theclinical thermometer probe cover or sheath onto and from thetemperature taking device in accordance with the manufactur-ers instructions, apply air at a positive internal gage pressureof 8.4 kPa (1.2 psi) with the probe cov

27、er or sheath submergedin water within the operating temperature environment (See4.7) to the length that is intended for patient contact. Thereshall be no continuous bubble stream observed within 5 s.Thermometer probe covers and sheaths that are intended toinvert when the temperature-taking device is

28、 withdrawn maybe tested while inverted.5.4 Compatibility Test:5.4.1 The compatibility of the clinical thermometer probecover or sheath with any particular temperature-taking devicefor which it is recommended shall be tested to verify that itmeets the device manufacturers performance characteristics.

29、5.4.2 A probe cover or sheath shall not degrade the perfor-mance (such as measurement time or accuracy) of thetemperature-taking device so that it fails to meet the require-ments of the applicable ASTM standards for the particulartemperature-taking device (for example, Specifications E 667and E 1112
