Description
Technical field
The present invention relates to technical field of medical equipment, and in particular to a kind of tourniquet.
Background technique
Existing tourniquet is refined using medical macromolecular materials natural rubber or specific rubber, milky, strip
Platypelloid type, point connect stack-type mounted box, and retractility is strong, can continuity extraction.It is defeated conventional therapy and treatment suitable for medical institutions
Liquid, blood drawing, blood transfusion, when hemostasis, are disposable；Or emergency hemostasis when extremity hemorrhage, field snakebite and bugbite bleeding.
It is generally needed before vein puncture using tourniquet, pricking the tourniquet time should not be too long, too long easily at local group
Hypoxic-ischemic is knitted, skin cyanosis, blood vessel traveling is unobvious or blood vessel is shriveled, and is unfavorable for puncturing successfully.After puncturing successfully, pine is stopped
Blood band.But the case where tourniquet is retained in patient after there is puncture, tourniquet is removed not in time, will cause disease
People four refer to anoxic necrosis, have been reported that display one old man be admitted to hospital after by nurse's first be its venous transfusion.First is 3 lis on patient's right arm elbow
Upper tourniquet is pricked at rice, after completion venipuncture fixed hour, is covered tourniquet since the coat-sleeve of patient slides, so
Forget to take off tourniquet.Subsequent first will go the child to oneself to breast-feed, and nursing staff's second is handed over to continue to complete doctor's advice.Second elder generation intravenous injection
Then medical fluid connects perfusion tube and carries out fluid infusion.In infusion process, patient repeatedly proposes " arm pain and drop speed are too slow " etc., second
Think that pain is caused by stimulating vein due to tetracycline, and to explain: " because of the reason of state of an illness, the speed of intravenous drip is not
It is preferably too fast ".By 6 hours, 500 milliliters of liquid have been finished, infusion niidl is removed by nurse third, have found local mild swelling,
It is thought due to a small amount of intravenous extravasation, does not give processing.After venipuncture 9 and a half hours, when doing hot compress because of patient's local pain,
Family members just have found that tourniquet is also pricked, and then solution is got off and reported and advises continuation hot compress after nursing staff's second, second are checked immediately, but not
Report doctor.4 hours after tourniquet is loosened, nursing staff's second discovery patient's right forearm palmar have 2 centimetres of 2 Х, two, bubble, accidentally
It is considered scald caused by hot compress, still unreported and processing.Spent 6 hours, right forearm height swelling again, bubble increase and
The back of the hand is blue, and nursing staff's second ability is reported Xiang doctor and president.President organizes the consultation of doctors to determine to turn higher level hospital, because not relating to rescue
The provisional anti symptom treatment of vehicle.Two days later, patient's right forearm distal end 2/3 is purple, have to multiply tractor and be sent to higher level hospital.For etc.
To family members' opinion, third day lower 1/3 amputation in right upper arm after transferring from one hospital to another.But draw because patient is old and frail plus poisoning infection
The heart, renal failure are played, in death in postoperative one week.It can be seen that tourniquet take will cause consequence very serious not in time,
Especially some senile dementias and coma patient are more, remove from a patient not in time, and consequence is hardly imaginable.Therefore it needs to grind
It sends out a kind of and reminds the tourniquet removed in time of medical staff after vein puncture success.
