Abstract
The utility model relates to a hemospast which is composed of a needle, a needle tube, and a test tube. The utility model is characterized in that the needle tube is a straight rod which is provided with a center fine through-hole whose diameter is 1-3 mm, the head of the needle tube is tightly inlaying connected and communicated with the needle, a rubber piston which tightly matches with the internal diameter of the test tube is sheathed and fixed on the tail end of the needle tube, the test tube is sheathed on the needle tube, and the negative-pressure suction needle cylinder is formed by the test tube, the rubber piston, and the needle tube. The hemospast and the test tube are combined into integration. The utility model has the advantages of novel design, simple structure, and low cost, and is dual-purpose.
Description
This utility model relates to a kind of hemostix.
At present, scientific research, hospital laboratory need blood experiment or check, usually general syringe is adopted in blood drawing, blood is delivered to again and sent to experiment or check in the test tube, its complicated operation needs twice operation, and after using up at every turn, test tube also needs artificial cleaning and sterilizing, labor intensity is big, and even now still unavoidably has the phenomenon of cross-contamination to take place.
The purpose of this utility model is exactly in order to address the above problem, and a kind of disposable test tube hemospast easy to use, free of contamination is provided.
Technical solution of the present utility model:
A kind of disposable test tube hemospast, it is made up of syringe needle 1, needle tubing 2 and test tube 3, it is characterized in that needle tubing 2 be one have in the straight-bar of careful through hole 6, the aperture of thin through hole 6 is 1-3mm, the head of needle tubing 2 is closely pegged graft with syringe needle 1 and is communicated with, its tail end overlap intrinsic one with the friction tight rubber piston 4 of test tube 3 internal diameters, test tube 3 just is sleeved on the needle tubing 2, makes test tube 3 and rubber piston 4 and needle tubing 2 thereof constitute the negative pressure-pumping syringes.
This utility model is with hemostix and two one of test tube, design is unique novel, simple and reasonable for structure, a thing dual-purpose, save medical treatment cost, this utility model once-through operation simultaneously puts in place, is disposable product again, so need not the cleaning and sterilizing operation, greatly reduce labor intensity, workload reduces about 50%, operate more simply, can effectively avoid the phenomenon generation of cross-contamination.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the aperture of careful through hole 6 the best is 2mm in the needle tubing 2 of the present utility model, so both overcome thin through hole too hour blood coagulation stop up the problem of needle tubing, it is excessive and problem that test tube vacuum is descended guarantees that operation is reliable, safety to have solved thin through hole simultaneously again.On needle tubing 2 and further along position syringe needle 1 splicing position, be provided with the projection 5 of projection, they are an integral body, pinch usefulness for operator's finger, the length of the test tube 3 then length with projection 5 aft section of needle tubing 2 is identical, at the external rear face of test tube 3 mark the scale indication is arranged, with what of control blood sampling volume.When this utility model uses, finger on the other hand pinches the projection 5 of needle tubing 2, syringe needle 1 is inserted human vas, this moment, test tube 3 all was positioned on the straight-bar of projection 5 aft section of needle tubing 2, pull out test tube 3 backward with another hands, because the internal diameter and the rubber piston 4 of test tube 3 are tight fit, then test tube 3 is pulled out backward and is formed negative pressure in the Shi Qiguan, the blood of human body flows in the test tube 3 with regard to careful through hole 6 in cleansing pin head 1 and the needle tubing 2, when the blood of extracting out in the test tube 3 reaches desired scale, can extract syringe needle 1, pull up test tube 3, complete operation, this moment, syringe needle 1 and needle tubing 2 can be abandoned, blood in test tube 3 and the pipe thereof is directly sent to check or experiment, and test tube 3 is a disposable product also, uses up promptly and throws.
Claims (5)
1, a kind of disposable test tube hemospast, it is made up of syringe needle 1, needle tubing 2 and test tube 3, it is characterized in that needle tubing 2 be one have in the straight-bar of careful through hole 6, the aperture of thin through hole 6 is 1-3mm, the head of needle tubing 2 is closely pegged graft with syringe needle 1 and is communicated with, its tail end overlap intrinsic one with the friction tight rubber piston 4 of test tube 3 internal diameters, test tube 3 just is sleeved on the needle tubing 2, makes test tube 3 and rubber piston 4 and needle tubing 2 thereof constitute the negative pressure-pumping syringes.
2, disposable test tube hemospast according to claim 1, it is characterized in that needle tubing 2 in the aperture of careful through hole 6 is best is 2mm.
3, disposable test tube hemospast according to claim 1 is characterized in that the further along position with syringe needle 1 splicing position of needle tubing 2 is provided with projection 5, pinches usefulness for operator's finger.
4,, it is characterized in that the length of test tube 3 should be identical with the length of projection 5 aft section of needle tubing 2 according to claim 1 or 3 described disposable test tube hemospasts.
5, disposable test tube hemospast according to claim 1 is characterized in that at the external rear face mark of test tube 3 the scale indication being arranged.
