Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
2. Healthcare Hazards
• Health hazards include chemical hazards (solvents, adhesives,
paints, toxic dusts, etc.), physical hazards (noise, radiation, heat,
etc.), biological hazards (infectious diseases), and ergonomic risk
factors (heavy lifting, repetitive motions, vibration).
3. Main Classes Of healthcare hazard
• There are four main classes of health hazard namely
1. Corrosive
2. toxic
3. harmful and
4. irritant.
4. 1.Corrosive
• Corrosive material which may cause skin
burns and permanent eye damage.
• Avoid contact with skin and eyes
• Do not breathe vapours or sprays
• Wear protective clothing
5. 2.Toxic
• Toxic material which may cause life
threatening effects even in small amounts and
with short exposure.
• Do not swallow the material, allow it to come
into contact with skin or breathe it
6. 3.Harmful
• May cause serious and prolonged health
effects on short or long term exposure.
• Do not swallow the material, allow it to come
into contact with skin or breathe it
7. 4.Irritation
• May cause irritation (redness, rash) or less
serious toxicity.
• Keep away from skin and eyes.
• Avoid release to the environment
8. Hazard Control Management
• Hazard control management focus on developing processes or
systems that can help prevent harm and loss.
• An uncorrected hazard or hazardous situation could contribute to
an event resulting in property damage, job interruption, personal
harm, or adverse health effects.
• The process of controlling hazards requires development of
written policies, plans, or procedures.
• The hazard control functions connect with organizational
structures and operational philosophies.
11. The main ways to control a hazard
• Elimination (including substitution): remove the hazard from the
workplace, or substitute (replace) hazardous materials or
machines with less hazardous ones.
• Engineering Controls: includes designs or modifications to plants,
equipment, ventilation systems, and processes that reduce the
source of exposure.
12. The main ways to control a hazard
• Administrative Controls : controls that alter the way the work is
done, including timing of work, policies and other rules, and work
practices such as standards and operating procedures (including
training, housekeeping, and equipment maintenance, and personal
hygiene practices).
• Personal Protective Equipment: equipment worn by individuals to
reduce exposure such as contact with chemicals or exposure to
noise
13. Seven Values of Hazard Control
Management
1. Never-ending process
2. People focused
3. Leadership driven
4. Operational priority
5. Benefits everyone
6. Reduces organizational losses
7. Prevents human harm
14. Hazard Analysis
• It collects the information regarding hazard surveys, inspections,
hazard reports and accident investigation.
• Hazard evaluations and accident trend analysis improve the
effectiveness of established hazard controls.
• Routine analysis enables an organization to develop and
implement appropriate controls forhazardous processes or unsafe
operations.
• This analysis process can provide a snapshot of hazard
information.
16. 1.Change analysis
• Change analysis is an proactive problem-solving technique.
• Change analysis helps hazard control, personally identify hazards related
to new processes and job- related tasks.
• Change analysis attempt to identify all anticipated hazards and concerns
generated by the change.
• Begin by defining a problem or concern.
• Identify distinctive features of any change and list all possible causes.
• Finally, select and validate all causes before continuing with corrections
or controls.
17. 2.Creative hazard analysis
• Creative hazard analysis combines innovation with human expertise to
identify, discover, and analyze hazards of a process, operation, or
system.
• The analysis team understands the problem statement.
• As the team works through each step of the hazard process, it should
collectively generate a list of what or why questions related to hazards.
• After completing this list of probing questions, the team must
systematically answer each question.
• The team works to achieve a consensus on each question and answer.
• The answers that achieve consensus form the foundation for developing
recommendations or dictating the requirement for additional action or
study.
18. 3.Risk analysis
• Risk analysis helps hazard control personnel assess the probability
that an uncontrolled hazard could contribute to an accident event
with resulting organizational losses.
• Risk assessments consider the potential severity associated with
an adverse event occurrence.
• Risk personnel consider hazards with acceptable risks as safe and
those with unacceptable risks as unsafe.
19. 4.Phase hazard analysis
• Phase hazard analysis processes work very well for construction
projects.
• Prior to transitioning to a new phase, conduct an analysis to
identify and evaluate new or potential hazardous.
• Use the information gained through analyses to develop action
plans that can ensure implementation of appropriate controls.
20. 5.Process Hazard Analysis
• Process hazard analysis recommend during the design and
development phases of any hazardous project or operation under
development.
• Process hazard analysis permits employers to accomplish detailed
studies to identify every potential hazard.
• The analysis must show that each element of the process poses no
hazard, poses an uncontrolled hazard, or poses a hazard
controllable in all circumstances.
21. 6.Job Hazard Analysis
• Job hazard analysis (JHA) permits the examination of job-related
tasks, operations, and process to discover and correct inherent
risks and hazards.
• Supervisors and other experienced personnel can perform the JHA
process for understanding potential job hazards by using an
effective teaching tool.
• Organizations should develop, conduct and update a JHA for all
tasks, processes with standardized procedures and formats.
22. • IBFCSM was founded in 1976.
• As a not-for-profit credentialing organization, operated for some
time as the Board of Certified Hazard Control Management
