Problems solved by technology

[0002] Disposable intravenous infusion sets currently used in the market do not have an automatic cut-off function. During the intravenous infusion process, when the liquid medicine is infused, if the flow regulating valve is not closed in time to stop the infusion, or the bottle is renewed to change the medicine, it will cause downtime. Air intake, blood return, and coagulation of the infusion tube cause obstacles to the continuation of the infusion, add additional pain to the patient, and are also prone to thrombus formation, which brings potential harm to the patient; the existing disposable infusion set is not equipped with a three-way pressure detection port. It is impossible to use the most simple, economical and practical method to carry out real-time monitoring and management according to the pressure changes in the infusion tube during infusion, which consumes a lot of hidden labor for medical staff; family members take care of patients with infusion. A large number of public resources in the society; the time to replace the liquid medicine or stop the infusion cannot be accurately grasped, and the infusion work can not be guaranteed to be processed in time, which affects the service quality and work efficiency of the medical staff; the inventor has previously designed a variety of technical solutions to Solve the above-mentioned problems, obtain innovation and breakthrough on multiple problems, but the inventor is still exploring and trying to find and thoroughly solve the best way and the most effective way to solve the problems of automatic cut-off, reflux, negative pressure utilization and other problems in the intravenous infusion. Simple and practical method

Embodiment Construction

[0094] Now with regard to the structural schematic diagram, this patent is specifically explained: attached figure 1 As shown, in the actual infusion application, the liquid medicine flows from the medicine bottle into the lower section 1-1 of the Murphy's tube of the infusion set, and the liquid medicine in the pipe flows from the liquid inlet tank 1 of the two-way negative pressure stop valve 1-2 under the action of gravity. -2-1-1, into the liquid inlet hole 1-2-1-2, under the pressure of the liquid medicine, the liquid medicine in the liquid inlet 1-2-1-3 pushes the elastic stop-flow latex film covering it The sheet 1-2-2 expands, and the liquid medicine flows into the expansion space below it, and at the same time flows into the stop valve sealing the liquid outlet 1-2-1 in the center of the diversion surface 1-2-1-5 -4 and the valve body liquid outlet pipe 1-2-1-8, flow out from the valve body liquid outlet 1-2-1-10, and then flow into the latex guide 1-3- in the negativ...

Abstract

The invention relates to a novel disposable venous transfusion double-direction positive pressure and negative pressure cut-off negative pressure conducting device. A double-direction negative pressure flow stopping device, a negative pressure conducting tee joint and a one-way pressure check valve are arranged between the lower section of a Murphy's tube and a lower infusion duct of disposable infusion apparatus, so that the infusion apparatus can be cut off automatically after completion of infusion or in the process of infusion, and backflow blood return can be prevented in any state. Meanwhile, pressure change information is generated and conducted. The negative pressure conducting tee joint on the device is used for reserving a port for external acoustic alarm and outputting information. According to the negative pressure conducting device, original infusion apparatus is improved little, cost is low, industrial production can be realized easily, the working habits of medical workers are not changed, and popularization and application are convenient. Moreover, the negative pressure conducting device can effectively improve the working efficiency of nurses and reduce patient pain.

Description

technical field [0001] The invention relates to a new type of automatic cut-off device for disposable intravenous infusion, in particular to a device capable of using the positive and negative pressure generated by the gravity of the liquid medicine in the infusion set to realize automatic cut-off and prevent blood return during the infusion process. Automatic cut-off device for air negative pressure conduction structure. Background technique [0002] Disposable intravenous infusion sets currently used in the market do not have an automatic cut-off function. During the intravenous infusion process, when the liquid medicine is infused, if the flow regulating valve is not closed in time to stop the infusion, or the bottle is renewed to change the medicine, it will cause downtime. Air intake, blood return, and coagulation of the infusion tube cause obstacles to the continuation of the infusion, add additional pain to the patient, and are also prone to thrombus formation, which ...
