Embodiment 1

[0031] like Figure 1.1~Figure 1.3 As shown, the single-cylinder pre-filled flushing pipe sealer in Example 1 is mainly composed of a cylinder body, a core plug 4 and a core rod 6, the core plug 4 is installed at the front end of the core rod 6, and the core plug 4 and the core rod 6 are placed together in the barrel, the length direction of the core rod 6 is in the same direction as the length direction of the barrel, the front end of the core plug 4 is parallel to the bottom surface of the barrel, the barrel is used to store flushing liquid, and the core The front end of the plug 4 is provided with a liquid storage device 3 for storing the sealing fluid. When the core rod 6 and the core plug 4 are pushed forward, the liquid storage device 3 is pushed forward, and the liquid storage device 3 releases the sealing tube after touching the bottom surface of the cylinder. liquid.

[0032] like Figure 1.1~1.5 As shown, the liquid storage device 3 in Embodiment 1 is an elastic ca...

Embodiment 2

[0045] The difference between embodiment 2 and embodiment 1 is that the structure of the liquid storage device 3 is different, and the structure of the liquid storage device 3 in embodiment 2 is as follows Figure 2.1~Figure 2.5 As shown, it is mainly composed of a cylindrical cuff 3a, a front sealing plate 3b and a plug 3c, the rear end of the cylindrical cuff 3a is sealed and combined with the core plug 4, and the front end of the cylindrical cuff 3a is installed with a front sealing plate 3b , the center of the front sealing plate 3b is provided with a liquid outlet, and the liquid outlet is blocked by a plug 3c, and the plug 3c seals the liquid outlet under the pressure of the sealing liquid of the cylindrical cuff 3a; the plug 3c A hollow top plate 3d is connected to the top, and when the liquid storage device 3 advances until it touches the bottom surface of the cylinder, the hollow top plate 3d is held up, so that the plug 3c is separated from the liquid outlet hole on t...

Embodiment 3

[0047] The difference between embodiment 3 and embodiment 1 is that the structure of the liquid storage device 3 is different, and the structure of the liquid storage device 3 in embodiment 3 is as follows Figure 3.1~Figure 3.5 As shown, it is mainly composed of a cylindrical cuff 3a, a front sealing plate 3b and a plug 3c, the rear end of the cylindrical cuff 3a is sealed and combined with the core plug 4, and the front end of the cylindrical cuff 3a is installed with a front sealing plate 3b , the center of the front sealing plate 3b is provided with a liquid outlet, and the liquid outlet is blocked by a plug 3c, and the plug 3c seals the liquid outlet under the pressure of the sealing liquid of the cylindrical cuff 3a; the plug 3c A thimble 3e is connected to the top of the cylinder, and a jacking tube 10 is provided at the center of the bottom surface of the cylinder. The top of the jacking tube 10 is closed, and the peripheral wall of the jacking tube 10 is engraved with ...

Abstract

The invention relates to a single-tube prefilled washpipe tube sealing device, comprising a barrel, a core plug (4) and a core bar (6); the core plug (4) is installed at the front end of the core bar (6), the core plug (4) and the core bar (6) are set in the barrel together, the length direction of the core bar (6) is the same as that of the barrel, and the front end face of the core plug (4) is in parallel with the bottom surface of the barrel. The tube sealing device is characterized in that the barrel is used for storing pipe flushing liquid, a liquid storage device (3) for storing the tube sealing fluid is installed on the front end face of the core plug (4), the liquid storage device (3) is pushed forward when the core bar (6) and the core plug (4) are pushed ahead, the tube sealing liquid is released after the liquid storage device (3) is contacted with the bottom surface of the barrel. Each component part of the tube sealing device is mutually limited, fixed and stabilized after being assembled, so that the phenomenon of falling apart does not appear, further causing damage and waste when transporting and using; the tube sealing device has small volume, thereby being low in transportation and storage costs, and being convenient to use, the component parts are equipped with structures for limiting each other, so that the washpipe and the tube sealing are simple in operation and safe and reliable.

Description

technical field [0001] The invention relates to a single-tube pre-filled tube flushing and sealing device, which belongs to the technical field of medical devices. Background technique [0002] Vascular indwelling catheter is a medical device widely used in clinic. It is easy to operate, safe and convenient. It not only solves the pain of repeated puncture for patients, protects blood vessels, but also reduces the nursing workload of nurses. Patients without self-awareness who need multiple injections but are difficult to get needles, especially critically ill patients, can open the blood vessel channel at any time to improve the success rate of rescue. During the retention of the vascular indwelling tube, it is necessary to flush and lock the tube with quasi-physiological fluid and heparin saline after each infusion or medication, so as to avoid blood backflow and thrombus formation during locking the tube, which will cause blockage of the vascular indwelling tube. [0003...
