Summary
A new closed-container umbilical cord blood collection device enhances safety for healthcare workers by reducing infectious agent exposure risks. This simple-to-use instrument facilitates guarded-needle vacuum tube collection, minimizing needle-stick injuries.
Area of Science:
- Obstetrics and Gynecology
- Medical Device Development
- Infection Control
Background:
- Obstetric personnel face risks of infectious agent exposure during cord blood sampling.
- Existing methods may pose risks such as needle-stick injuries and direct blood contamination.
Purpose of the Study:
- To develop and evaluate a novel closed-container device for safe umbilical cord blood collection.
- To assess the efficacy and safety of the new device in reducing occupational hazards.
Main Methods:
- A modified closed-cup instrument was utilized for guarded-needle vacuum tube blood collection.
- Gravity drainage within the sealed device facilitated blood collection.
- Factors influencing collected volume, including heparin addition and cord characteristics, were examined.
Main Results:
- The mean volume of cord blood collected was 6.1 +/- 3.1 mL.
- Adding heparin increased the collected volume by approximately 2 mL.
- Only 1.6% of samples yielded less than 1 mL of blood; cord diameter and length correlated with volume.
Conclusions:
- The closed-container umbilical cord sampling device significantly reduces risks of needle-stick injuries and blood contamination for healthcare professionals.
- The device is simple to operate, allows for safe disposal, and is suitable for use by physicians and nurses.
- This innovation offers a safer approach to cord blood collection in clinical settings.

01:54The Spinal Cord
31.9K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

8.5K
Data collection gathers information needed to make accurate judgments about a patient's present condition. During a health history interview, subjective data is collected from the patient, their caregivers, or family members, and objective data is collected through observations and physical assessment. Patients are the primary source of subjective data. Thus information gathered from patients through interviews, observations, and physical examination is primary data. Secondary sources of...

In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
