Problems solved by technology

[0002] The structure of the disposable infusion set currently used is relatively simple. Because there is no self-cutting function, during the intravenous infusion process, when the liquid medicine in the infusion set is nearly empty, if the infusion is not stopped in time or the liquid medicine is replaced, the lower infusion tube will enter. Qi, blood return, and coagulation will hinder the continued infusion, add extra pain to the patient, and easily form thrombus, which will bring potential harm to the patient; because the existing disposable infusion set is not equipped with a three-way pressure detection port, it cannot be used according to the infusion. Real-time monitoring and management of the pressure change information in the infusion tube consumes a lot of hidden labor for the medical staff. They cannot accurately grasp the time to replace the medicinal solution or stop the infusion, and cannot guarantee that these tasks can be handled in time, which affects the health of the medical staff. Service quality and work efficiency, solving these problems in intravenous infusion is the current top priority

Embodiment Construction

[0054] Below in conjunction with structural representation accompanying drawing, the present invention is described in detail, as figure 1As shown, the negative pressure transmission device 1-2 is combined with the lower part of the Murphy's tube 1-1, the O-ring 1-4, the lower infusion catheter connector 1-5, and the suspension sealing plug 1-6 to form an intravenous infusion set Self-blocking negative pressure conduction device 1. During the infusion process, the medicinal liquid flows from the lower liquid outlet 1-1-1 of the Murphy's tube 1-1, flows into the liquid inlet 1-2-1-2 of the diversion tube, and enters the left liquid chamber 1-2-1 -3, the medicinal liquid flows out from the outlet 1-2-1-4 of the left liquid chamber, and enters the diversion bag 1-2-2, and the medicinal liquid is inside the diversion bag 1-2-2, from bottom to top, After the air is exhausted, the liquid medicine inlet 1-2-1-7 of the right liquid chamber flows into the right liquid chamber 1-2-1-6,...

Abstract

The invention relates to a negative pressure conduction type self-cutoff device of a disposable venous infusion apparatus. The inside of a Murphy's tube is additionally provided with a suspension sealing plug, the lower part of the Murphy's tube is additionally provided with an O-shaped sealing ring, and the negative pressure conduction device is arranged between the lower liquid outlet of the Murphy's tube and a lower infusion guide tube. After the infusion is completed, the cutoff is automatically carried out, the pressure changing information is generated and conducted, and a negative pressure conduction three-way port arranged on the negative pressure conduction device is reserved with an interface for the outside acousto-optic alarming and outputs information. The negative pressure conduction type self-cutoff device has the advantages that the change of the structure of the original infusion apparatus is little, cost is low, and industrialized production is easily realized; and the working habit of medical staff is not changed, popularization and application are convenient, the working efficiency of nurses is effectively improved, and the pain of patients is reduced.

Description

technical field [0001] The invention relates to a self-cutting negative pressure conduction device of a disposable venous infusion set, in particular to a device capable of automatically shutting off, preventing blood return, and simultaneously generating and utilizing negative pressure conduction. Background technique [0002] The structure of the disposable infusion set currently used is relatively simple. Because there is no self-cutting function, during the intravenous infusion process, when the liquid medicine in the infusion set is nearly empty, if the infusion is not stopped in time or the liquid medicine is replaced, the lower infusion tube will enter. Qi, blood return, and coagulation will hinder the continued infusion, add extra pain to the patient, and easily form thrombus, which will bring potential harm to the patient; because the existing disposable infusion set is not equipped with a three-way pressure detection port, it cannot be used according to the infusion...
