Description
Technical Field
The utility model belongs to the technical field of the heparin cap, concretely relates to take disposable heparin cap of heparin sodium tube sealing liquid.
Background
Central Venous Catheters (CVCs), peripherally implanted central venous catheters (PICCs) and other Central Venous Access Devices (CVADs) are access routes for fluid management, nutrient infusion and blood sampling in clinical care, which need to be maintained for days or even weeks, and thus maintenance of vascular access is particularly important, especially to prevent catheter dysfunction due to thrombus formation within the catheter. The catheter lock of dilute heparin sodium solution is a routine step in central venous catheter maintenance. After the transfusion or treatment is finished, the pipeline is flushed and sealed by heparin again, and the heparin cap is replaced; or after the operation is finished (if the heparin cap is not removed), puncturing the heparin cap to wash and seal the tube. Regular maintenance of the catheter is required even if the catheter is not used for a long period of time.
In the prior art, the main operation steps are to use diluted heparin sodium solution to seal the tube after the tube is flushed by normal saline. The technology has the following defects: firstly, when the injector is pulled out, because a certain negative pressure is generated, the blood at the tip of the catheter is easy to flow back, and the probability of catheter blockage is increased; secondly, the syringe needs to be replaced twice (once the syringe is filled with normal saline, and once the syringe is filled with diluted heparin sodium solution), so that the infection risk caused by exposure of a catheter port and misoperation in the replacement and injection process is increased; finally, the diluted heparin sodium solution needs to be prepared additionally, and the problems of improper heparin concentration preparation, excessive or insufficient push of the tube sealing liquid, pollution in the preparation process and the like can occur.
In order to solve the above problems, those skilled in the art have developed various assemblies, including a needle-free positive pressure connector, and when the syringe is pulled out after the normal saline is flushed and sealed, due to a certain positive pressure generated in the connector, blood at the tip of the catheter is not easy to return, and the probability of blockage is reduced, for example, the needle-free positive pressure connector disclosed in chinese patent CN203169727U, the needle-free injection positive pressure connector disclosed in chinese patent CN203898862U, and the needle-free dosing positive pressure connector disclosed in chinese patent CN101879339B, the above-mentioned various needle-free connector parts are compact and complex, the production cost is higher than that of a common heparin cap, which can increase the medical cost and the hospitalization cost of the patient, and the positive pressure connector belongs to a semi-open connector, the exposed sterile surface can repeatedly enter and exit the infusion device, and the related infection of the catheter is easy to occur, and the heparin cap belongs to a fully. Secondly, in order to solve the problem of preparing a tube sealing solution separately, the cap lock solution comprising citrate and benzoate disclosed in U.S. Pat. No. 5, 8226971, 2 produces a finished tube sealing solution without the trouble of preparing separately, but does not reduce the number of syringe replacements and the problem of improper push-in dose of the tube sealing solution.
Therefore, the research on the disposable heparin cap with heparin sodium catheter-sealing liquid has become a technical problem to be solved in the field.
