Technical field
The present invention relates to a kind of contact maker that is used to help sample to be sent to the point-of-care test case from syringe.
Background technology
Many medical procedures need carry out diagnostic assay on the sample of patient's body fluid.Body fluid is normally by adopting a kind of needle holder assembly and one or morely smoking that pipe collects from patient on one's body.Also can be in syringe with humor collecting.Syringe can use to obtain body fluid samples on one's body from patient with metal needle.But syringe usually directly directly is connected to obtain fluid sample with artery of being set up or intravenous line.The body fluid that is collected in the syringe can be transferred in the pipe then.Carefully that these pipes are labelled and deliver to the laboratory so that analyze.Turn one's head then the result of lab analysis is reported to the health doctor.Certainly, in emergency condition, may press for these results, but the time of extracting sample from patient out to the time that lab analysis is reported to the health doctor, need more than one day usually on one's body.
Developed and be used at the scene that Division of Nursing carries out the device of some diagnostic assay at least on body fluid samples.This point of care diagnostics equipment comprise be used for from patient receive on one's body body fluid samples syringe, be used to receive from the small-sized disposable test case of the part body fluid of syringe and the portable clinical analysers that is used to analyze this body fluid and output result.Being combined on the American market of test case and portable clinical analysers sold by i-STAT, AVL scientific ﹠ technical corporation and Diametrics Medical company limited.These systems that produced by these and other companies have some common features.Specifically, the test case of each system have usually about 1 inch * 2 inches and thick be 0.25 inch rectangular enclosure.This shell comprises the internal container of volume between about 40 μ l and 125 μ l.Inlet extends through the outer wall of test case and communicates with internal container.This test case also comprises contact chip and the sensor that can be arranged to link to each other with portable clinical analysers.In U.S. Patent No. 5638828, demonstrate the embodiment of i-STAT point-of-care test case.
The point-of-care assay system of prior art has adopted and has been used for extracting out from patient the syringe of body fluid samples on one's body.This syringe can be used for a part of liquid is injected into the inlet of point-of-care test case then.But some test cases can automatically be extracted body fluid out from syringe.Then the inlet of test case is sealed and this test case is arranged to link to each other so that carry out special diagnostic assay on the body fluid samples in test case with portable clinical analysers.Analyser is exported result of laboratory test soon and body fluid samples need not be delivered to the laboratory then.
The point-of-care assay system has several being better than in fact need be in the effect of carrying out all diagnostic assay away from the on-the-spot position of nursing.The small size of test case helps depositing of test case and transports the portability that also helps system simultaneously.But for sample collected being transferred to test case, these little test cases are very difficult to use.For example the inlet of the end of syringe and test case aim at complicated and difficult.The misalignment of syringe and the inlet of test case or out of true cooperate can cause losing the collected body fluid samples of a part.In addition, be difficult to use the syringe of the body fluid that is used for accurately distributing correct volume.Volume very little can hinder test case to carry out correct chemical examination with relevant portability clinical analysers.Too many volume can cause and splashes or overflow.Overflow equally and can cause when closing the lid of point-of-care test case, splashing.The fluid that advances the inlet of test case from injector delivery effectively can not produce the potential danger of transmission.Equally, send to from syringe test case during the loss of body fluids leptochymia that causes being left to carry out desired diagnostic assay.The fluid volume that carries out needed chemical examination is not enough, then needs the healthcare worker to extract second fluid sample on one's body again out from patient.This has just wasted the time and has been subjected to wound again for patient for the healthcare worker.In addition, some test cases can need to throw away the box of fully not filling, and adopt the new box with new liq sample.Therefore, from syringe the poor efficiency that fluid sends test case to can be produced too much cost for extra test case.
Directly fluid being sent to test case from syringe can cause that the syringe top is closed entry port and prevented and discharge the air test case.Therefore produce bubble.Bubble can reduce the volume of fluid and can influence result of laboratory test.
Usually use the IV channel system of pipe and joint that liquid solution is flowed to patient.A kind of such joint is blunt nosed plastic tube, the tube chamber that it has relative near-end and far-end and extends between them.Partly be provided with big tapered opening near the tube chamber of adapter of plastic near-end, its size set for can realize with the tapered tip of Luer joint for example in the top fluid-tight engagement of the far-end of syringe.The near-end of adapter of plastic comprises a pair of lug relative on diameter, these flanges be configured to the Luer flange on internal thread engagement.Lug makes the top of Luer joint pack into tightly in the conical entrance of the tube chamber that leads to adapter of plastic with being threadedly engaged with of internal thread of Luer flange on adapter of plastic.Therefore, the adapter of plastic of prior art can realize that the fluid-tight of the far-end that connects with the firm mechanical connection of Luer flange and with Luer is connected.The distal-most end of this adapter of plastic terminates in the single axially aligned outlet, and it is similar to the diameter of tube chamber that this exports its diameter.
Adapter of plastic has been used on the multiple medical application, comprises medicine is injected in the joint of IV pipeline.But, adapter of plastic also be not used in bloodletting usually or any diagnostic procedure of after having collected blood sample, carrying out in.
