Abstract
The utility model relates to a hemostix, in particular to a disposable test tube hemostix. The utility model is to overcome the disadvantages of the disposable injector in the collection of the blood, and to provide a disposable test tube hemostix. The utility model comprises a rubber piston, a push rod, a baffle with two lugs, a test tube and a shield. The utility model is characterized in that the inner wall of the bottom of the test tube has lug boss, while the external wall has worm and the front end also has worm; the inner wall of the bottom of the shield has worm which is fitted with the worm at the front end of the test tube; the inner wall of the baffle with two lugs has worm to fitted with the worm at the rear end of the test tube; and the rubber piston is flexibly connected with the push rod through connecting element and worm. The advantages of the utility model are: the ratio of the blood splash is reduced, thus, the environment is protected and the operating staff is secure; when the blood is collected, the blood can be delivered to be tested without any test tubes, therefore, the cost of blood test is reduced.
Description
Technical field:
This utility model relates to a kind of hemostix, especially relates to a kind of disposable test tube hemostix.
Background technology:
The hemostix of prior art, what adopt usually is disposable syringe, and disposable syringe mainly uses aspect two in hospital; The one, the injection that injection for curing is used in human body, the 2nd, the venous blood samples sample is for chemical examination; Disposable syringe is made up of syringe 1, rubber piston 2, push rod 3 and ears baffle plate 4; Rubber piston 2 be contained in the syringe 1 and the inwall of syringe 1 slide and with the inner wall sealing of syringe 1, ears baffle plate 4 is installed in the bottom of syringe 1, push rod 3 is affixed with rubber piston 2, and passes ears baffle plate 4, referring to Fig. 1.There are two kinds of shortcomings in this kind structure, and the one, behind blood sample collection, must transfer in vitro can chemically examining of chemical examination usefulness to blood sample again to blood sample collection; The 2nd,, because of operator's carelessness, the accident that blood spatters outward takes place, thereby cause the pollution of environment and personnel's infection on every side easily when test tube shifts blood sample at syringe, directly have influence on medical personnel or other staff's healthy problem.
Summary of the invention:
The purpose of this utility model is, overcomes above-mentioned two kinds of shortcomings that disposable syringe exists when blood sample collection, promptly must be in test tube shifts blood sample and shifts blood spatter outside easily, a kind of disposable test blood sampling tube device is provided.
This utility model is achieved in that disposable test blood sampling tube device, is made up of rubber piston 2, push rod 3, ears baffle plate 4, test tube 5 and cover cap 6; It is characterized in that: described test tube 5 is cylindrical structural, and the inwall of its bottom is provided with boss 51, and outer wall is provided with screw thread 52, and the outside of front end also is provided with screw thread 53; The inwall of the bottom of cover cap 6 is provided with screw thread 61, and matching with the screw thread 53 of test tube 5 front ends is connected; The inwall of ears baffle plate 4 is provided with screw thread 41, and is connected with the screw thread 52 of test tube 5 rear ends; Rubber piston 2 is installed in the test tube 5, and cooperates with the inner wall sealing of test tube 5, and its trailing flank is provided with connector 21 and is threaded with the top of push rod 3.
The utility model has the advantages that, after blood sample collection is finished, do not need blood transfer is arrived in vitro, reduced the chance that blood spatters outward, both helped environmental conservation, help operator's health again; After carrying out blood sample collection, do not need to dispose again test tube, just can directly inspect by ready samples, saved the cost of blood testing; One time the test tube hemostix also has the function of syringe simultaneously, can substitute syringe and use.
Description of drawings:
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is a decomposing schematic representation of the present utility model.
Specific embodiments:
Below in conjunction with accompanying drawing, this utility model is specifically described, disposable test blood sampling tube device is made up of rubber piston 2, push rod 3, ears baffle plate 4, test tube 5 and cover cap 6; Described test tube 5 is a cylindrical structural, and the inwall of its bottom is provided with boss 51, outer wall is provided with screw thread 52, and the outside of front end also is provided with screw thread 53; The inwall of the bottom of cover cap 6 is provided with screw thread 61, be connected with the screw thread 53 of test tube 5 front ends, the inwall of ears baffle plate 4 is provided with screw thread 41, and be connected with the screw thread 52 of test tube 5 rear ends, rubber piston 2 is installed in the test tube 5, and cooperate with the inner wall sealing of test tube 5, and can slide in test tube 5, its trailing flank is provided with connector 21 and is threaded with the top of push rod 3.
Using method: can extract blood by the operational approach of syringe during use, after blood draw is finished, the rubber piston 2 in the disposable test blood sampling tube device, by pulling push rod 3, run to the bottom, disassemble push rod 3 and ears baffle plate 4 immediately, be provided with boss 51 in the bottom because of test tube 5, thereby rubber piston 2 and connector 21 can not come off, because the sealing function of rubber piston 2, blood can not leaked, then test tube 5 is erected, disassemble the cover cap 6 of test tube 5 heads.At this moment, disposable test blood sampling tube device just becomes a test tube that contains blood sample, can be used for chemical examination and uses.
