Description

A kind of transfusion accessory that detects transfusion liquid parameter

Technical field

The utility model relates generally to a kind of transfusion accessory, and for example Infusion bottle lid, relates in particular to one and can detect transfusion liquidThe transfusion accessory of body parameter.

Background technology

The clinical use of result present stage is carried out dosing process before to(for) infusion products does not have test request, studies carefully that it is formerBecause being is more stranded in there is no conveniently detection means. Such as to the acid-base value that configures rear solution, osmotic pressure, drug concentrationEtc. the detection of index, each index is all the parameter for clinical treatment quality with material impact, but existing means are notReliable and means of testing efficiently can be provided. Given this,, by whole central aspects, can think in infusion process for liquidAnd the medium between human body only has infusion bottle system and infusion pipeline system (transfusion device, vein/arterial duct etc.). Infusion pipeline withoutThe meeting that method is avoided produces cross pollution, all can not ensure the measuring accuracy of every kind of medicine or solution. Know therefrom, realAddress the above problem and will in infusion bottle system, find breakthrough, varied due to production process, Infusion bottle lid is that have most canThe crucial accessory that can address the above problem. In view of crucial point, in sensor or detection components design and Infusion bottle lid, logicalCross while work and the contacting of liquid, testing result is drawn fast, thus guiding clinical treatment.

By the literature research to infusion treatment, in the process of transfusion, needing the key index of controlling is acid-base value, electrolysisDegree, osmotic pressure, active ingredient concentration, particulate matter etc. Detect for diverse one or several indexsRequirement, need to carry out specially designed sensor or checkout gear detects. Taking acid-base value as example, dosing process each timeIn acid-base value whether be in the interval as drug effect maximum. By sensor or checkout gear by the Data Detection after making up a prescriptionOut, thereby reach the sensing of adjustment, reach best result for the treatment of by adjustment.

By the detection to other data, can draw the index of different results for the treatment of. By the principle of evidence-based medicine EBMInvestigation infusion reaction and influence factor. Draw following table:

The routine infusion reaction medicining condition of table 1102

Tab1Medicineof102infusionreactions

As can be seen from the table, add a kind of case of medicine mostly to be 38.2% most, 45% the transfusion of simultaneously having an appointment is again controlledThe compatibility transfusion of multi-medicament has been carried out in treatment, and transfusion index and the parameter of compatibility transfusion are to draw by experience like this, andAnd also and find no the result of study of pertinent literature. So particularly necessary and there is clinical value by the detection before transfusion.Because transfusion large usage quantity, general consumption is at the extremely thousands of milliliters of 100mL, if a certain index generation great change will be produced curative effectRaw tremendous influence. Country has strengthened GMP (pharmaceutical producing enterprise's quality control procedure), GCP (medical institutions' preparation configuration in recent yearsQuality control procedure) management, but still the generation that can not at all stop injection quality event, it is serious that to be called as adverse drug anti-Answer (ADRs), by the following bad reaction distribution situation list of going out of the sample study to adverse events.

Table two:

Routine time of ADRs generation and drug type, kind quantity

From recording of bad reaction in form, anti-infectives is the multiple medicine of adverse drug reaction, analyzes and sends outParameter drift-out after when raw reason, all have that particulate exceeds standard, pyrogen, acid-base value exceed standard etc. made up a prescription, is all stranded in can not be before transfusionEffectively monitor.

During for the mensuration of osmotic pressure molar density, normal human's body fluid osmotic pressure molar density mean value is 298, normalScope is between 280-310. Venous transfusion directly enters blood, and mainly important on erythrocytic impact, venous transfusion isWhen the medicine of Hyposmolality, hydrone enters red blood cell through cell membrane, makes red blood cell spalling cause haemolysis, and vein is defeatedWhile entering the medicine of hyperosmosis, in red blood cell, moisture oozes out, thereby makes cellular atrophy. So the quality of venous transfusion reaches as far as possibleTo isosmoticity or higher osmotic pressure. Chinese pharmacopoeia is revised osmotic pressure molar density determination method from 2000 editions beginnings in annex,And clearly specify the preparations such as venous transfusion, nutrient solution, electrolyte or osmotic diuresis medicine (as formula mannitol injection liquid), should be in labelClearly regulation shows its osmotic pressure molar density, so that clinician's reference, state's Extra Pharmacopoeia Martindale is also included this project, and pharmacopoeia of each country is logicalThe normal method test molar concentration that adopts cryoscopic method indirectly testing is all the number of the detection that can not carry out during the courseValue by add electronics or nonelectronic sensor in transfusion system, is carried out data the easiest test before transfusion,It is clinical huge demand. Known by document, due to production environment difference, the product of the same kind that different enterprises produceProduct, osmotic pressure molar density all has very big difference, is distributed in different concentration intervals, and this gives the clinical potential treatment that broughtRisk. Glucose in transfusion, the Main Function of sodium chloride be regulate preparation etc. ooze, glucose, sodium chloride in enterprise prescriptionAddition determine by calculated value often, but due to the mutual work between solute molecule or between solvent molecule in solutionWith, the actual osmotic pressure of product often calculates lower than theory, so best test is, before medication, product is waited to infiltrationThe test of pressing, guarantees drug safety.
