Abstract
The invention relates to a vein remaining needle which mainly comprises a remaining rubber tube, a puncture needle guide disc, a sealing tube plug and a puncture needle, wherein the vein remaining needle is provided with at least one hirudin injection device capable of preventing blood from forming thrombi in the vein remaining needle; the liquid injection outlet at the bottom of the hirudin injection device can be selectively communicated with the inner cavity of the vein remaining needle; and the inner cavity of the hirudin injection device is filled with a hirudin biological anticoagulant, and the top is provided with a driving device capable of driving the hirudin biological anticoagulant in the inner cavity to be injected into the inner cavity of the vein remaining needle. Because the vein remaining needle adopts the hirudin as an anticoagulant and fully utilizes the super strong and super long anticoagulation properties of the hirudin biological anticoagulant, the vein remaining needle fully guarantees that the blood flowing back into the vein remaining needle because of a negative pressure can not generate thrombi, thereby ensuring the smoothness of each channel of the vein remaining needle, avoiding the adverse impact resulted from puncturing again and utilizing heparin sodium which should be used immediately after being prepared, and effectively reducing the pain of patients and the labor strength of medical personnel. Besides, the invention has the advantages of easy manufacturing process and simple implementation, and is beneficial to popularization.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments that is used for infusion liquid, a kind ofly specifically be used for behind the artery and vein puncture remaining needle of indwelling phase infusion liquid in blood vessel in blood vessel.
Background technology
Transfusion almost can be imported human body by blood vessel with all medicinal liquids, realizes treatment and prophylactic purpose.In clinical, usually can be because of periodic treatment plan, repeatedly puncture vessel carries out infusion treatment.In processes such as chemotherapy, cardiovascular and cerebrovascular diseases and children's, old people's blood vessel condition (sclerosis, fragility increase) to tumor differ from, patient's blood vessel is damaged because of repeatedly puncturing, or due to illness the people mismatches, can increase the painful and puncture procedure difficulty of patient, even can destroy that (the blood vessel injury portion after the puncture can form cicatrix because of the repeatedly puncture of showing shallow blood vessel, blood flow is logical more difficult in a short time), and the use of can not puncturing once more, influence infusion treatment, finally the deep vascular puncture need be realized the treatment transfusion.The damage that causes blood vessel for avoiding repeatedly puncturing and reduce patient's misery also for alleviating nurse operation intensity, has generally been used iv cannule (pipe) technology in clinical.It is by the technical scheme (apparatus) of a soft tube pin is set at metal puncture pin outer surface, in the vascular puncture process, the soft tube pin is brought into blood vessel, pull out the metal puncture pin again, and the soft tube pin is retained in endovascular liquid infusion apparatus-sound fat remaining needle.Thereby prolong the indwelling time of soft pin in vein blood vessel, reduce the misery and the loaded down with trivial details work of puncture once more.The iv cannule of present clinical use is made up of heparin (sealing) medicated cap, puncture needle, puncture needle positioning disk, indwelling soft tube pin, indwelling needle stand, remaining needle protective sleeve mostly.They can be finished the vascular puncture process substantially and keep somewhere the indwelling (bury stay) of soft tube pin in artery and vein vascular; But the iv cannule that uses has following many defectives and deficiency now: to accepting is that there was security risk in personnel around patient reached: because it is identical with common puncture needle positioning disk structure to keep somewhere needle stand, there are not the measure or the device that prevent blood (backflow), make after puncture needle is pulled out, blood can reflux, contaminated environment and (medical personnel and surrounding population) human body form security risk; Moreover, using remaining needle to repeat in the infusion process, the infusion connector after once transfusion finishes is pulled out action, must make the remaining needle inner chamber form certain negative pressure, can cause and keep somewhere in the needle tubing and blood refluxes to enter to keep somewhere in the needle tubing blood coagulation can take place, it is stifled to form bolt, has destroyed the remaining needle passage.When reusing,, can influence treatment and increase medical personnel's work because of the remaining needle passage stops up; Moreover the intravasation if the stifled blood clot of bolt comes off then can enter the tissue or the organ of human body different parts with blood flow, causes the thromboembolism of this tissue or organ blood vessel, the serious ischemia that causes this organ, necrosis, and consequence is very serious and dangerous.And increase medical care intensity, operate loaded down with trivial details, and take place bolt stifled after, need puncture again, can increase patient's misery and burden, its application is restricted.For this reason, the remaining needle of present clinical use, its protection rules are after pulling out joint, must use a kind of helmet, and the remaining needle interface is sealed, in order to prevent that blood from solidifying in keeping somewhere needle tubing, must use anticoagulant (heparin sodium aqua) again, be injected in the indwelling tube (so that this closing cover is also referred to as calparine cap), be specifically designed to remaining needle is carried out the anticoagulant tube sealing, per 4～8 hours once, the strict execution.This had both increased the operation of medical workers program, had also increased patient's financial burden, also because the patient of some blood coagulation mechanism obstacle can not use this class chemistry anticoagulant of heparin sodium because of the hemorrhage risk of haemolysis, its application was restricted; In addition, when being carried out the anticoagulant tube sealing, remaining needle, also increased medical personnel by the danger of pricking wound owing to be to adopt acupuncture manipulation.
Summary of the invention
