Description
Technical field
The present invention relates to aseptic experiment room or the bottle opener of operating room, more particularly to a kind of specimen bottle cap-opening mechanism and right
The sample bottle cap answered.
Background technology
What the monitoring of hospital or aseptic experiment room for indoor bacteria content was strict, because slight misoperation
The infringement for causing sufferer infection is very big, such as inside-hospital infection, posts the bacterium or bedsore pathogen grown in intestines and stomach
After polluting urethral orifice, bladder can be invaded by catheter or bladder is reached by the thin layer liquid between catheter and mucous membrane of urethra, led to
The most common approach that urethral catheterization lumen is bacterial invasion is crossed, bacterium enters after pollution catheter, drainage tube and urine collector leads
Urinary catheter chamber, the retention catheterization guard system cross pollution as caused by the hand of staff play important work in bacterium infection is disseminated
With, in addition, bacterium still enters urinary tract by the flushing liquor and various drug solutions, the cystoscope of non-strict sterilization etc. of pollution,
The chance that bacteruria disease occurs after urethral catheterization is 1%~5%, places retention catheterization Guan Erwu encloseds sterilization collection device person, 48h
Bacteruria disease is found in 90% patient afterwards；There is enclosed to sterilize collection device person, bacteruria disease is detected in 20%~25% patient, feels
Dye incidence increases with catheter standing time, and it is 5%~10% often to place one day chance for bacteruria disease occur, is placed 2 weeks
More than 50% patient will infect afterwards,
Surgery wound infection for another example:S. aureus L-forms are the important pathogenic bacteria of wound infection, are infected typically in postoperative 3~8 days
Occur, contagion is important compared with air borne between average of operation periods, interpatient cross-infection or from staff in postoperative ward
Carrier, typically all may be from patient in itself by contact transmission, some S. aureus L-forms wound infections, coagulase-negative grape ball
Bacterium, streptococcus and enterococcus spp are also the encountered pathogenic bacteria of wound infection, and Gram-negative bacilli seldom obtains from operating room
, in ward, the wound infection caused by gram negative bacilli accounts for the 60% of whole wound infections, including green pus bar
Bacterium, Escherichia coli etc.；Posted in addition to external source venereal disease opportunistic pathogen and grow the bacterium of patient's Yu enteron aisle, respiratory tract etc. and can also be used as wound infection
Pathogenic bacteria, such as gastrointestinal surgery and abdomen puncture are hindered in pneumoretroperitoneum and wound infection i.e. predominantly endogenic bacteroides fragilis
Causing with aerobic gram negative bacilli, the anaerobic bacteria such as bacteroid is also the common pathogen of gynecological surgery postoperative infection,
Or ALRI:It is pharyngeal to post the pathogenic bacteria grown and may be from patient's intestines and stomach, also can be by intersecting between patient
Infection is obtained, respirator, sprayer by the propagation of corpsman,hospital's hand, and humidifier etc. can all turn into spread of germs
Medium, it can be that gram negative bacilli growth creates condition, tracheotomy disease that some therapeutic equipments, which have liquid storage device equipment person,
People loses pharyngeal defense function；Non-sterile over the course for the treatment of or traumatic suction sputum simultaneously, the flushing liquid of pollution, antibiotic
Treatment, the elderly's long-term bed, the secretion of suction is not removed and the intermittent pressurized respirator that pollutes etc. is all to promote
The factor that pulmonary infection occurs, clinical obvious infection occurs for about 20% patient after chest and upper abdominal surgery, up to half patient
There is x-ray evidence to show some postoperative pulmonary complications, smoking, original pulmonary lesion, operating time will increase art more than 2 hours etc.
The incidence of postoperative infection, pneumonia typically occurred in postoperative 2~4 days, and pathogen is the most common with gram-negative bacteria, account for 60~
80%, it is especially more common with Enterobacters such as the enterobacteriaceae lactobacteriaceaes such as Klebsiella and Pseudomonas aeruginosas, also can be Bacillus influenzae,
S. aureus L-forms, pneumococcus, legionella pneumophilia etc., easily causing when humoral immune function is low has capsular bacterium (Bacillus influenzae, pneumonia
Coccus) caused by pneumonia, the low patient Yi Yinqi aspergillus of cellular immune function, Mycotoruloides, Pneumocystis carinii, giant cell disease
The pulmonary infections such as poison, herpes zoster virus, chlamydia trachomatis, anonymous mycobacteria category, legionella pneumophilia, stupor, shock etc.
Patient Ke Yin suck oral secretion and occur anaerobic bacteria (peptococcus, peptostreptococcus, Fusobacterium etc.) or anaerobic bacteria with
Aerobic bacteria mixed infection, Respiratory Syncytial Virus(RSV) are the most important pathogen of infant's ALRI in 2 one full year of life, and it is fallen ill
Rate and case fatality rate are high.
So in some are sterile or patient's infection rate is high ward, laboratory, it is as far as possible most of using instrumentation
Back work, reduce manual intervention because manual intervention can not only improve the content of indoor bacteria, in addition, staff nor
Chang Rongyi in high germ room bacteria infection so as to cause a disease.
General hospital directly enters the sample of all kinds of rotary lid mechanisms in operating room to realize under state with cover, grasps
Work is that interior meeting be provided with rotating mechanism, but existing rotating mechanism entangles bottle cap by the cushion rubber of inside to be rotated, and this mode is non-
There is the phenomenon skidded in Chang Rongyi, and so as to cause corkage to fail, reduces operating efficiency.
