Description

The intravenous infusion needle needle cap of radionuclide drug allotment returns plug-in unit

Technical field

The utility model relates to field of radiation therapy more particularly to a kind of venous transfusions of radionuclide drug allotment Needle needle cap returns plug-in unit.

Background technique

Radio nuclide examination English name: radionuclide examination be using radionuclide and its A kind of method that labeled compound diagnoses disease and studies.The modern doctor developed rapidly after the 1950s Learn one of important diagnostic technology.

And the function of radio nuclide examination is very much, such as radiopharmaceutical is introduced human body, uses radioactivity prospecting Instrument measures radioactivity in internal organs in body surface and changes with time, and passes through computer reduced time-activity curve and carries out Analysis obtains quantitative parameter for assessing organ function and diagnosing the illness.This law simplicity is inexpensive, most common to have renal function measurement And cardiac determination；

And radiopharmaceutical is introduced into human body, it then measures in related internal organs or radioactive dynamic becomes in blood, urine, feces Change, to understand the function of internal organs.Most common nuclear instrument is various functional examination instrument, body surface measure radioactivity in internal organs with The change curve of time carries out semi-quantitative analysis to this curve by computer or hand computation or is calculated according to certain mathematical model Various quantitative parameters out.This method has wide and practical applied the functional examination of Thyreoidine, heart, kidney and lungs. The case where taking orally radiolabeled protein or fat, measuring radioactive growth in blood and be discharged through fecaluria, it will be appreciated that Digestion and absorption function.The speed that radiolabeled various haemocyte injection veins, measurement radioactivity are disappeared in blood, can count Calculate the service life of haemocyte；Radioactivity is measured the case where the positions such as liver, spleen are gathered, hematoclasis or intercepted can be observed Position；

And radio nuclide examination can also realize the purpose of imaging, by radiopharmaceutical introduce in vivo after, in internal organs, Based on the difference absorbed between outer or normal tissue and lesion to radiopharmaceutical, imaging instrument is utilized to obtain internal organs or lesion Image.Common imaging instrument is gammacamera and emission computerized tomography camera (ECT), and the latter is divided into positive electricity again The PECT of the subtype and SPECT of monochromatic light subtype.It is divided into static state and two kinds of dynamic imaging in the way of imaging.Due to lesion The amount and the close phase such as speed and their blood flow, functional status, metabolic rate or receptor density of position intake radiopharmaceutical It closes, therefore gained image can not only show their position and form, it is often more important that can reflect the above-mentioned various of them Situation (may be collectively referred to as function status), therefore a kind of actually functional imaging.It is well known that the early stage of most diseases, Before morphosis changes, above-mentioned functional status has change, therefore radionuclide image usually can be than to show shape XCT, MRI, ultrasonic examination etc. based on state structure have found earlier and diagnose many diseases.

And radionuclide drug is before the injection, and medical staff is needed to carry out modification of drug in draught cupboard in advance, and medicine When object is deployed, disposable venous infusion needle certainly will be used with regard to needs, and during intravenous infusion needle clinical use, it is necessary to it is stringent Implement medical care precess regulation, absolutely to prevent the generation polluted before, after.

However, intravenous infusion needle clinical use process briefly described above, however it remains problems.First is that by It is disposed in the not fixation for the needle cap taken from syringe needle, often will cause needle cap and do not return pin head and be dropped, and generated seriously Problem of environmental pollution；Second is that the aperture due to needle cap is fine, sharp syringe needle is inserted into needle cap by medical worker, this will not only have Basic training really up to the mark, and to have preferable clinical setting brightness, it operates very inconvenient；Third is that in the operation of syringe needle insertion needle cap In the process, since hand has pinched syringe needle, the other hand has pinched needle cap, under such dynamic condition, even senior medical worker, Extremely it is easy to produce the problem of stabbing finger.And finger is stabbed, it is just likely to generate pathology pollution, jeopardizes medical worker's Own health.

For this purpose, providing a kind of easy to operate, it can be used in draught cupboard, avoid the disposable vein for stabbing human body defeated Liquid needle needle cap returns slotting device and becomes the expectation for medicinal to overcome the shortcomings of prior art.
