Embodiment 1

[0048] figure 1 It is a structural schematic diagram of the hirudin anticoagulant blood sealing kit of the intravenous indwelling needle according to the first embodiment of the present invention. Such as figure 1 As shown, the hirudin anticoagulant blood sealing tube kit of the venous indwelling needle of the first embodiment includes a sleeve 1 guided by a puncture needle and inserted into the vein, and a transparent three-piece sleeve connected to a built-in isolation sealing plug 3 at the rear end of the sleeve tube 1. 2 and the infusion connector 6 for connecting the infusion line or blood collection line.

[0049] One end of the transparent tee 2 is connected to the casing 1 , one end is sealed by an isolation sealing plug 3 , and the third end is connected to the infusion joint 6 through the extension tube 4 . The extension tube 4 is provided with a stopper 5 for stopping the flow of the liquid in the tube. The infusion connector 6 can adopt a single-lumen tube or a ...

Embodiment 2

[0055] figure 2 It is a schematic structural view of the intravenous indwelling needle according to the second embodiment of the present invention; image 3 It is a structural schematic diagram of the locking syringe of the second embodiment of the present invention. Such as figure 2 and image 3 As shown, the hirudin anticoagulant blood sealing tube kit of the intravenous indwelling needle in the second embodiment includes the sleeve tube 1 that is guided into the vein by the puncture needle 17, and the transparent three-piece of the built-in isolation sealing plug 3 that is connected to the sleeve tube 1 rear end. 2 and the infusion connector 6 for connecting the infusion line or blood collection line.

[0056] One end of the transparent tee 2 is connected to the casing 1 , one end is sealed by an isolation sealing plug 3 , and the third end is connected to the infusion joint 6 through the extension tube 4 . The extension tube 4 is provided with a stopper 5 for stoppin...

Embodiment 3

[0063] The hirudin anticoagulant blood sealing tube kit for intravenous indwelling needles according to the third embodiment of the present invention comprises a cannula inserted into the vein guided by a puncture needle, a transparent tee connected to a built-in isolation sealing plug at the rear end of the cannula and used for The infusion connector for connecting the infusion line or the blood collection line.

[0064] One end of the transparent tee is connected with the casing, one end is sealed by an isolation sealing plug, and the third end is connected with the infusion joint through an extension tube. The infusion joint can adopt a single-lumen tube or a double-lumen tube. If a single-lumen tube is used, the free end of the single-lumen tube is sealed by a sealing end cap; if a double-lumen tube is used, two different drugs can be infused simultaneously, and the two ends of the double-lumen tube are respectively sealed by the first sealing end cap and the second sealin...

Abstract

The invention discloses a hirudin anticoagulation seal tube kit for a vein detained needle. The hirudin anticoagulation seal tube kit for the vein detained needle comprises a casing, a transparent tee joint connected with the rear of the casing, and a transfusion joint connected with a transfusion pipe or a blood taking pipe; the seal tube kit for the vein detained needle also comprises a seal tube syringe of which one end of the transparent tee joint is immersed into the tube cavity of a detained needle; the seal tube syringe comprises a liquid storage tube in which a tube cavity is formed, a needle head part connected with the front end of a sealed tube, and a shell which is sleeved outside the liquid storage tube and of which the rear end is closed; a bulged clamping wire is arranged on the outer peripheral wall of the rear end of the liquid storage tube; a clamp groove is formed on the inner peripheral wall of the front end of the shell, and clamp steps at equal intervals are formed on the inner peripheral wall of the shell; and a seal plug connected with the rear wall of the shell is arranged in the liquid storage tube. The seal tube kit for the vein detained needle guarantees that the same doses of the seal tube liquid can be injected every time and the seal tube liquid is filled in the tube cavity of the detained needle. The seal tube liquid in the seal tube syringe is hirudin diluent, has good anticoagulation effect and cannot influence all indexes in the serum test in the blood.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a hirudin anticoagulant blood sealing tube kit for intravenous indwelling needles. Background technique [0002] In recent years, with the rapid development of medical science, intravenous indwelling needles that can reduce the pain of repeated punctures have been widely used in critically ill patients for rescue infusion, intravenous hypernutrition, and intermittent intravenous antibiotics or other drugs. Indwelling catheters include puncture needles and cannulas. After the puncture needle is inserted into the patient's vein with the cannula, the puncture needle is pulled out, the cannula remains in the body, and the outer end is connected to the infusion device or the blood collection device. The venous indwelling needle can not only be used for routine venous infusion, but also can be used for intermittent multiple blood collection, which not only avoids the pain caus...
