Assessment of the Abdomen III: Palpation

Assessment of the Abdomen III: Palpation

Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Physical Assessment of the Respiratory Tract II: Palpation

Physical Assessment of the Respiratory Tract II: Palpation

Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...

Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

Background:

Prostate cancer diagnosis and monitoring require accurate assessment of tissue mechanical properties.
Existing methods for in vivo mechanical property measurement are limited in precision and scope.
Micro-engineered devices offer potential for minimally invasive and high-resolution palpation.

Purpose of the Study:

To evaluate the operational functionality of a novel micro-engineered actuator assembly.
To validate the actuator's capability for measuring dynamic mechanical properties of the prostate gland in vivo.
To assess the performance of the micro-piston and associated components within the palpation device.

Main Methods:

Fabrication of a micro-actuator using deep reactive ion etching (DRIE) for a silicon piston.
Assembly of the micro-piston within a glass-Si-glass housing with a silicone membrane seal.
Integration of a micro-syringe pump and pressure sensor for controlled reciprocating motion and dynamic pressure measurement.
Utilizing powder blasting for micro-channel creation and capillary tubing for fluidic connection.

Main Results:

The micro-piston and actuator assembly were successfully fabricated and integrated.
The system demonstrated controlled reciprocating action via the programmable syringe pump.
The pressure sensor effectively measured dynamic pressure changes within the micro-channel.
Preliminary tests confirmed the micro-piston's capability to actuate and measure mechanical properties.

Conclusions:

The developed micro-engineered actuator assembly is functional for its intended purpose.
The device shows promise for in vivo measurement of prostate dynamic mechanical properties.
Further validation and clinical deployment are warranted for this micro-palpation technology.
