Description
【Technical field】
The invention belongs to the field of medical instrument technology.A kind of more particularly it relates to self-sealing venous detaining needle.
【Background technology】
The dosage of the big infusion of China's vein in 2013 is 10,400,000,000 bottles, and intravenous infusion device usage amount is 3,000,000,000 sets, and vein stays
Put pin dosage more than 300,000,000.They are mainly high public by the joint venture of U.S. company BD, joint venture of Bei Lang companies and Shandong prestige
The product of the productions such as department, Suzhou Lin Hua companies.
Venous detaining needle is also known as venous catheter needle, it is made of stainless steel needle core, outer tube and plastics needle stand.During puncture
Stainless steel needle core is pierced into blood vessel together with outer tube, after intravasation extract out stainless steel needle core, allow softness inlying catheter
It is left to remain in blood vessels and infuses.It is hose due to being retained in intravenous, avoids damage of the draw point to blood vessel, patient can band
Pin gentle activity.Venous detaining needle suitable for any position puncture, one-time puncture can continuously or interval multiple, more days use,
The pain that patient punctures repeatedly is alleviated, alleviates the workload of nursing staff, it is clinically deep to be suffered from welcome by shield, save at the same time
Substantial amounts of medical treatment and nursing manpower and materials, have a Health Economics meaning, thus the Nurses Association of China advocate it is defeated using remaining needle
Liquid, advocates " draw point zero tolerance ", it is proposed that the infusion treatment of more than 2 times is all using remaining needle in demonstration hospital at present.
Venous detaining needle need not be pulled out after infusion-completed to be remained to use again during infusion next time, is stopped after infusing due to vein
Blood back causes remaining needle plugging, therefore indwelling time length has a dispute always, administrative department of public health, Quality Control department of hospital and stays
Zhi Zhen producers all advocate that indwelling time is no more than 3-4 days.
Venous detaining needle plugging is that the blood coagulation substance such as blood platelet in blood is in low stream because blood backflow is into catheter lumen
Conduit intravascular coagulation, thrombosis and then the plugging of speed, must use tube sealing technology to prevent plugging to ensure that conduit can be reused,
" tube sealing " has become a specific term in medical treatment and nursing.A series of apparatus, medicine, behaviour are developed for " tube sealing "
Make technology, formulated a series of《Specification》、《Standard》.The renewal in every 4 years of venous transfusion association of the U.S. is once《INS venous transfusions
Practice standard》, it is at present《Venous transfusion practice standard version in 2011》, China's national health and Family Planning Committee are in 2013
Issue on November 14, in《Intravenous therapy nursing technical operation specification》, there is defined remaining needle tube sealing, it is specified that its standard.
" tube sealing " method in standard method is carried out using in physiological saline or heparin in sealing liquid injection conduit at present
" tube sealing ", its principle are that physiological saline or other tube-sealing solutions occupy conduit cavity space as working solution matter, make blood and its coagulate
Blood component cannot enter in conduit；Secondly the blood coagulation substance that the physiological saline in conduit can be diluted into, delays blood coagulation and thrombus
Formed.
This " tube sealing " nursing items need to use the equipment such as " positive pressure connector ", " tube-sealing solution ", " rinsing tube sealing syringe ",
Operated and completed by fine techniques such as " positive pressure tube sealings " of " pulsed is injected three times " and " withdraw of the needle in propulsive liquid ".This method increases
Add workload of the nurse；Disposable tube sealing irrigating syringe forms resource and wastes, and adds Biohazard Waste and is processed into
This, is unfavorable for environmental protection.
When the effective time about 4 of physiological saline " tube sealing " is small, the tube sealing that " tube sealing " is only used for intermittence infusion is somebody's turn to do, is exceeded
4 it is small when " tube sealing " heparin in sealing liquid must be used.Heparin is anticoagulation prescription medicine, and nurse cannot determine to use, therefore add
The workload of doctor；In addition, a part of patient be because constitution and the state of an illness cannot use heparin liquid tube sealing, when this kind of patient every 4 is small
" tube sealing " once, increases nursing work load, influences sleep rest, influences patient comfort.
At present, a kind of method for being closed or being opened conduit at needle stand using mechanical piston at indwelling needle implements " tube sealing "
Remaining needle, it is necessary to operate piston on needle stand, this external force is transferred in intravenous inlying catheter, makes catheter displacement, de-
Fall and scratch endangium, cause infusion leakage, infusion failure, phlebitis, phlebothrombosis etc..In addition this operation must both hands
Carry out, it is necessary to open remaining needle plaster, increase opportunities for contamination, workload of the nurse is larger.
Another self-enclosed remaining needle is to be separated into plemum and transfusing chamber two parts in its needle stand inner cavity, stops infusion
When the indoor liquid energy automatic slowly of positive pressure flow into transfusing chamber and reach " tube sealing ".This method flows into the liquid of infusion channel from plemum
Cognition is lost to intravenously, and the liquid of plemum finite capacity has flowed quickly, does not have positive pressure after having flowed, tube sealing effect is passed with the time
Subtract,.
In addition, also there are the other methods for setting counterflow-preventing machinery flap valve, duck-beak type to be unidirectionally open in catheter tip, because
" tube sealing " effect is not known, and listing is for many years in the U.S. and China《Venous transfusion practice standard》In it is recommended use, these
Product is commercially without trace.
The characteristics of self-sealing venous detaining needle of the present invention is that an as received basis liquid is set in conventional needle seat of remaining needle
Capsule pipe, by injecting working solution matter to as received basis liquid capsule pipe, it fills rear enclosed infusion channel, and working solution matter is in liquid capsule
