Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the process of infusing vasoactive drugs to critical patients in clinic, in order to ensure the accuracy of drug administration, a micro pump is selected for injection, and an injector and a lengthened extension tube (1.5 meters) are selected as an infusion device. For patients with extreme hemodynamic instability, a dual pump replacement was chosen.
The start-up delay of the micro syringe pump occurs after the micro syringe pump is stopped and restarted. For patients with extreme hemodynamic instability, a dual pump sequential pump change is required to overcome the delay in priming the micro-syringe pump itself. Meanwhile, in the process of replacing the liquid medicine, the syringe and the extension tube need to be separated, so that the pressure of the liquid medicine in the extension tube is easily attenuated due to improper operation, the pumping speed of the liquid medicine is influenced when a new syringe and a new infusion pump are connected to pump the medicine, and the hemodynamics of a patient is influenced.
In order to solve the above problems, referring to fig. 1, there is shown a schematic structural diagram of a positive pressure infusion syringe according to an embodiment of the present invention, which includes a syringe body, a positive pressure connector 2, an extension tube 3, and a three-way connector 4;
the syringe body is used for sucking and storing liquid medicine; one end of the positive pressure joint 2 is connected with the injector nipple 1 at the front end of the injector body, and the other end of the positive pressure joint 2 is connected with one end of the extension tube 3; the other end of the extension tube 3 is connected with an intravenous catheter through the three-way joint 4, and the intravenous catheter 5 is used for medicine infusion.
During the process of replacing the liquid medicine, the syringe and the positive pressure joint 2 are directly separated and then directly connected to the opened standby syringe and the micro pump. The positive pressure joint 2 ensures that the pressure in the extension tube 3 is always at the positive pressure level, and pressure attenuation cannot occur, so that the problems of start delay of the micro-injection pump and pressure attenuation in the extension tube 3 are solved, and fluctuation of hemodynamics caused in the process of replacing vasoactive drugs is reduced to the maximum extent.
The direct connection between the syringe for storing the liquid medicine and the infusion extension tube 3 in the prior art is improved, and the positive pressure connector 2 ensures that the pressure in the infusion extension tube 3 is stable in the process of replacing the liquid medicine. In the prior art connection, the pressure in the extension tube 3 is easily attenuated due to improper operation during the process of replacing the liquid medicine.
