Multifunctional air-check transfusion system

Abstract

The invention provides a multifunctional air-check transfusion system which comprises a bottle insertion needle, a hose, a drip chamber, a flow regulator, a transfusion needle and an air-check device, wherein the air-check device comprises a shell and an air check valve; the inner side wall of the shell is provided with a plurality of rails, the lower end of the shell is provided with a connection pipe, and a seal position is arranged between the lower end of the shell and the connection pipe; the air check valve is positioned in the inner cavity of the shell and comprises a floating ball and a sealing element; the interior of the floating ball is provided with a cavity, and the outer side wall of the floating ball is provided with a plurality of guide rings; clearances are reserved between the guide rings and the rails; the sealing element is positioned at the bottom of the floating ball and fixedly connected with the floating ball; the sealing element is made of a soft material. By virtue of optimally designing the air-check device and adopting the air check valve structure, the air check valve can float up and down freely in the shell; the sealing element structure and the sealing position structure are optimally designed, so that a favorable self-sealing effect is achieved, air is prevented from entering into the boy of a patient during a transfusion process, and the transfusion safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional gas-stop infusion set, which is suitable for intravenous infusion of patients. Background technique [0002] At present, disposable infusion sets are widely used for intravenous infusion of patients. However, the existing disposable infusion sets usually do not have the function of automatic sealing. If the medical staff or patients do not pay attention to the infusion, it is easy to cause air to be injected into the patient. Intravenous, thereby bringing great potential safety hazards to patients, and also causing unnecessary workload to medical staff. For this reason, it is necessary to add an automatic air stop device to complete automatic sealing and air stop. However, the existing air stop device usually adopts a sealed film structure, which leads to complicated production process, high manufacturing cost, difficulty in product acceptance, and qua...

[0002] At present, disposable infusion sets are widely used for intravenous infusion of patients. However, the existing disposable infusion sets usually do not have the function of automatic sealing. If the medical staff or patients do not pay attention to the infusion, it is easy to cause air to be injected into the patient. Intravenous, which brings great potential safety hazards to patients, but also causes unnecessary workload to medical staff

For this reason, it is necessary to add an automatic air stop device to complete automatic sealing and air stop. However, the existing air stop device usually adopts a sealed film structure, which leads to complicated production process, high manufacturing cost, difficulty in product acceptance, and qualified products. low rate defects
