In-Flight Urine Collection Absorber (IUCA)

Measurement Devices, Body; Measurement Devices, Physiologic; Sample Collection Devices, Urine/Feces; Waste Collection Devices

The IUCA consisted of a small, conical piece of high-absorbency filter paper that could be placed in urine collection funnels, which themselves were attached to the Shuttle waste collection system. The IUCA was a conical, 75 cm² filter that fit into the urine-collection funnel. The filter material could absorb 20.4 gm of water per 100 cm2, and weighed approximately 20 gm empty and 35 gm full. This assembly could be used by men and women, and could be used on the Shuttle middeck.

Theoretically, as the crew member voided, the vortex action created by the Shuttle's vacuum system would allow urine to saturate the IUCA. When the void was complete, the IUCA could be removed, placed in a double-ziplock bag, and stored in an absorber containment bag for return. This technology could be used only for experiments that did not require void volume to be measured.

By comparison, the urine-collection device (UCD) assembly, which could be used only by men, weighed 65 gm empty and 300-400 gm when full.

Operations Acquisition System In Situ

Computer Systems; Data Recorders

To maximize benefits from the data sent to the ground by the Lower Body Negative Pressure (LBNP) Controller and the Data Acquisition System, a new system was developed for data acquisition from the Shuttle downlink telemetry. The Operations Acquisition System In-situ (OASIS) is a portable, ground-based data processing system used to decode, display, and store information received from the Space Shuttle telemetry stream during LBNP operations in the middeck or the Spacelab. The OASIS can be used anywhere that access to telemetry data is available, such as the Science Monitoring Area (SMA) at JSC, the Payload Operations Control Centers (POCC) at MSFC and JSC, or during preflight testing in the Operations and Checkout Building at KSC.

The OASIS has a custom-designed Dual Serial Receiver board, together with special data acquisition cards in a personal computer (PC) system running customized software (developed under a LabViews platform). The OASIS system utilizes two PCs (laptops with expansion chassis or desktops) to perform all of the functions that have previously required two racks of electronic equipment, a MicroVAX computer and a network of Macintosh workstations. Virtual instrumentation displays on the PC monitors can be customized to perform data analysis in real or near-real time. Selected information can be displayed to investigators and medical personnel monitoring the experiment (blood pressure and heart rate trend analysis, pulse pressure monitoring, power spectral analysis of electrocardiograms, etc.). Alarms can be programmed to alert when heart rate or blood pressure approaches predetermined test termination criteria. The multitasking capabilities of the PC workstations are optimized to display data in multiple windows simultaneously.

Gas Delivery System (GDS)

Measurement Devices, Pulmonary

The Gas Delivery System is a sub-component of the Human Research Facility (HRF) respiratory physiology facility known as the Pulmonary Function System (PFS). The GDS provides calibration and respiratory gases for the calibration of the PFS compliment of gas analyzers used in the calculation of cardiovascular and cardiopulmonary parameters for metabolic physiology analysis. The development of the GDS is part of a collaborative effort between NASA and the European Space Agency (ESA) in the field of respiratory physiology instrumentation. The primary components of the PFS are the NASA-provided Gas Analyzer System for Metabolic Analysis of Physiology (GASMAP), the ESA-provided Pulmonary Function Module/Photo Acoustic Analyzer (PFM/PAM), and the Gas Delivery System (GDS). The GDS used in combination with the PFM may replace the function of the current GASMAP Calibration Module as well as enhance science capabilities and flexibility of on-orbit gas replacement.

The GDS is a 4 Panel Unit (PU) drawer with no power or data interfaces. The GDS can store any combination of five gas cylinders of calibration and respiratory gas mixtures for use with the PFM. The PFM then distribute the gas mixtures appropriately to support various science activities.

Functional Requirements - the Gas Delivery System (GDS) shall:

Accommodate five gas cylinders with associated plumbing

Provide a manual shutoff (isolation) for each cylinder

Provide an individual outlet for each cylinder

Provide quick disconnect fittings on all outlets

Provide external fill connections (although not necessarily in a location accessible during normal use) so that the cylinders may be filled without disassembly

Provide a pressure gauge for indication of gas volume- the pressure gauge reading will be visible in normal use, with the pressure reading port upstream of the manual valve, so that pressure may be read at all times without manipulation of valves

Provide a method of replacement of an individual gas cylinder assembly

Be 100% oxygen compatible

Be designed to 2400 psi (20685 kPa) working pressure

Provide capability to access up to 200 liters of gas [Standard Temperature and Pressure, Dry (STPD)] volume capability (dependent upon investigation protocol) in each cylinder

Produce a flow greater than 0.4 liters/sec with a flow stability of ± 10ml/sec at the outlet pressure of 50 psi (345 kPa)

Be two-fault tolerant with relief valves sized and set to insure that the outlet pressure for each cylinder will not exceed 70 psi.

Have a leak rate of not more than 1 psi (6.896 kPa) per day (manual valves closed) and not more than 10 psi (68.95 kPa) per day (manual valves open) when filled to maximum pressure.

Holter Electrocardiograph (ECG) Monitor

Measurement Devices, Cardiovascular

The Holter Monitor is an ambulatory data collection device. It consists of an analog cassette recorder, capable of recording the electrocardiogram (ECG) continuously in two separate channels for 24 to 48 hours. Five chest electrodes are connected by an electrode harness to the monitor. Channel 1 approximates a Modified Lead V1, and channel 2 approximates a Modified Lead V5.

The Holter Monitor used, Model 90205, is manufactured by Spacelabs Medical, Inc. It contains an ECG gain switch that can be set to x0.5 or x1.0, and it has a liquid crystal display (LCD) that provides a reference time to coordinate the recording with a diary kept by the subject. The monitor requires two types of batteries. A standard 9-V DC alkaline battery supplies power to the tape drive motor and the electronic circuitry. Power is supplied to the electronics whenever the battery is installed. Power is applied to the motor whenever the recorder cover is closed. Two 1.5-volt silver oxide batteries supply power to the clock circuits whenever the 9-volt battery is not installed.

While in use, the monitor is placed in a Nomex pouch with a strap, which is strapped around the subject's shoulder or waist. There is an event marker on the monitor which allows the subject to note any symptoms or specific activities taking place. When the event marker is pressed, a 32- Hz rectangular wave is superimposed on the ECG signals. The ECG input voltage is 5 mV (+2.5 mV from baseline) at x1.0 gain, and 10 mV(+5mV from baseline) at x0.5 gain).

There are 3 training units and 6 flight units currently available.

Phonocardiograph

Measurement Devices, Cardiovascular

Phonocardiography is the recording of heart sounds and murmurs using electromechanical apparatus. The phonocardiograph is used in the diagnosis and monitoring of heart disorders. This instrument produces phonocardiograms by using a system of microphones and associated recording equipment. One microphone is usually placed on the chest near the base of the heart; another is positioned on the chest over the apex of the heart. The microphone placed over the base of the heart records the timing of the aortic and pulmonary components of the second heart sound and the loudest murmurs. The microphone placed over the apex is connected to special filters that allow the recording of low frequency sounds, such as those associated with atrial and ventricular gallops, as well as higher frequency sounds, such as those associated with mitral regurgitation and ventricular septal defect. To ensure an accurate recording, the examiner also uses audiophones to monitor the sounds and an oscilloscope to monitor cardiac impulses.
