Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses when concrete implementation, a be applied to two-chamber syringe of single chamber CVC towards sealing tube, including medicine chamber 1 and normal saline chamber 2, medicine chamber 1 and normal saline chamber 2 link to each other, and the bottom is equipped with needle mouth 3, and medicine chamber 1 and 2 bottoms in normal saline chamber and needle mouth 3 link to each other, and the junction is equipped with one-way valve 4, and medicine chamber 1 and 2 inside push rods 5 that are equipped with in normal saline chamber, and one side that medicine chamber 1 was kept away from in normal saline chamber 2 is equipped with buckle 6, and 5 tip of push rods are equipped with and push away platform 7, push away platform 7 and the cooperation of buckle 6.

As a modification, the medicine cavity 1 and the physiological saline cavity 2 have the same volume and are both 10ml.

As an improvement, the top of the buckle 6 is provided with an inclined plane, so that the push table 7 can be pushed in conveniently.

As an improvement, the surfaces of the medicine cavity 1 and the physiological saline cavity 2 are both provided with obvious marks.

The utility model discloses a theory of operation: 1. both lumens of the double-lumen syringe were 10ml.

2. The physiological saline cavity and the medicine cavity are respectively marked with an obvious mark: heparin solution/0.9% sodium chloride, distinguished by color or marked visibly.

3. The end of the pintle is provided with a buckle, the injection of 0.9 percent of sodium chloride is less than 5ml, and the pintle can not be withdrawn after being fixed in the injection tube cavity.

4. The end of the injector can be provided with a single-cavity valve, and the physiological saline and the heparin solution can be prevented from being mixed evenly under the standing condition; when the normal saline is injected into the flushing pipe, the normal saline can be prevented from entering the heparin liquid end.

5. According to the CVC tube sealing double-cavity injector, a nurse can complete the work of flushing and sealing the tube through one injector in the clinical nursing work. Including an injector outward appearance, two syringe chambeies are equipped with 0.9% sodium chloride and 10U/ml's heparin liquid respectively, set up the buckle on the syringe pintle after having pushed 0.9% sodium chloride in the bolus, make the needle file that is equipped with 0.9% sodium chloride block when pushing the liquid and being less than 5ml in the bolus, prevent to push the palirrhea to another injection chamber of 10U/ml's heparin liquid in the bolus. The purpose that one injector can wash and seal the tube is achieved.
