Product Overview
Figure 1: Welch Allyn 767 Wall Aneroid Blood Pressure Monitor.
This image displays the Welch Allyn 767 Wall Aneroid blood pressure monitor. It features a large, square black dial with white markings for blood pressure readings, housed in a light-colored square casing. Below the dial, a black inflation bulb and a long, black coiled tubing are visible, connecting the unit to a cuff (not shown). The entire unit is designed for wall mounting.
Components:
- Aneroid Gauge: The main display unit with a laser-engraved dial and high-contrast red pointer.
- Inflation Bulb: Used to inflate the blood pressure cuff.
- Coiled Tubing: Connects the gauge to the inflation bulb and the blood pressure cuff.
- Wall Mount Bracket: Secures the aneroid to the wall.
Setup Instructions
- Choose Location: Select a suitable wall location, preferably near the examination area, ensuring it is at eye level for easy reading.
- Mounting: Securely attach the wall mount bracket to a sturdy wall stud or use appropriate wall anchors. Ensure the bracket is level before tightening screws.
- Attach Aneroid: Carefully slide the Welch Allyn 767 Aneroid onto the mounted bracket until it clicks securely into place.
- Connect Tubing: Connect the coiled tubing from the aneroid to the blood pressure cuff. Ensure all connections are snug to prevent air leaks.
- Initial Check: Before first use, perform a quick visual inspection to ensure all components are intact and properly connected.
Operating Instructions
Follow these steps for accurate blood pressure measurement:
- Patient Positioning: Have the patient sit comfortably with their arm supported at heart level. Ensure they are relaxed and have not exercised or consumed caffeine/nicotine recently.
- Cuff Placement: Select the appropriate size blood pressure cuff. Wrap the cuff firmly around the patient's bare upper arm, ensuring the artery marker on the cuff aligns with the brachial artery.
- Inflation: Close the air release valve on the inflation bulb. Rapidly inflate the cuff by squeezing the bulb until the gauge reads approximately 20-30 mmHg above the patient's usual systolic pressure, or until the radial pulse is no longer palpable.
- Deflation and Reading: Slowly open the air release valve to deflate the cuff at a rate of 2-3 mmHg per second.
- Systolic Pressure: Note the reading on the aneroid gauge when you first hear the Korotkoff sounds (a tapping sound).
- Diastolic Pressure: Note the reading when the Korotkoff sounds disappear or become muffled.
- Release Air: Fully open the air release valve to deflate the cuff completely.
- Repeat Measurement: If necessary, wait at least 1-2 minutes before taking another reading on the same arm.
Maintenance
Proper maintenance ensures the longevity and accuracy of your Welch Allyn 767 Wall Aneroid.
- Cleaning: Wipe the aneroid gauge and tubing with a soft cloth dampened with a mild disinfectant solution. Do not immerse the unit in liquid.
- Storage: When not in use, ensure the cuff is neatly stored and the tubing is not kinked or stretched.
- Calibration: Regular calibration is crucial for maintaining accuracy. Consult a qualified service technician for annual calibration checks or if you suspect inaccurate readings.
- Inspection: Periodically inspect the tubing for cracks or leaks, and the inflation bulb for proper function.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Cuff size incorrect, improper cuff placement, air leak, device needs calibration. | Ensure correct cuff size and placement. Check for leaks in tubing/cuff. Schedule professional calibration. |
| Cuff Does Not Inflate | Air release valve open, leak in tubing/cuff, faulty inflation bulb. | Close valve. Check all connections for leaks. Replace faulty components if necessary. |
| Gauge Needle Jumps Erratically | Rapid cuff deflation, patient movement, internal gauge issue. | Deflate cuff slowly (2-3 mmHg/sec). Ensure patient stillness. Contact service if issue persists. |
