Description

Technical Field

[0001] The utility model belongs to the technical field related to infusion pumps, and particularly relates to an infusion pump capable of preventing pollution. Background Art

[0002] An infusion pump is an instrument that can accurately control the number of infusion drops or the infusion flow rate, ensuring that the drug can enter the patient's body at a uniform speed, accurate dosage and safely. At the same time, the infusion pump can also improve the efficiency and flexibility of clinical drug administration operations and reduce the workload of nursing. The infusion pump is usually a mechanical or electronic control device, which controls the infusion speed by acting on the infusion catheter, but it still has the following disadvantages in actual use:

[0003] During the operation of the infusion pump, the liquid is directly delivered to the catheter and then to the external delivery pipeline. During the operation, when different drugs need to be delivered using the same infusion pump, the catheter needs to be cleaned before the delivered drug solution can be replaced. During the operation, other drug solutions are easily retained in the infusion pump, causing contamination of different delivered drug solutions;

[0004] The catheter and power components in the infusion pump are designed in an integrated manner. When the service life of the pipeline is reached, it is necessary to disassemble the infusion pump as a whole, remove the catheter in the infusion pump, and then install the new catheter before performing the overall installation operation. The catheter replacement operation is inconvenient. Utility Model Content

[0005] The utility model aims to provide an infusion pump that prevents contamination. By arranging a support frame, an active cavity and an infusion pipe fitting, the utility model solves the problem that the infusion pump is prone to drug contamination when the drug is transported, and the catheter replacement requires the inconvenience of overall disassembly.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is an infusion pump to prevent contamination, comprising a support frame, an active cavity and an infusion pipe fitting, an inner box body is fixed on one side of the support frame, an active bar is fixed on the bottom of the support frame on one side of the inner box body, an inner plate is fixed on the middle of the inner wall of the inner box body, a turntable is arranged above the inner plate, a rotating rod is fixed in a circular array at the top edge of the turntable, the top of each rotating rod is rotatably connected to a pressure plate, an active cavity is movably connected in the support frame outside the active bar, and the bottom of the active cavity is movably connected to the active bar. On the outside, an infusion tube is movably connected to one side of the upper part of the movable cavity close to the inner box body, and a movable hole is opened on the front side of the movable cavity. The infusion tube is movably connected in the movable hole. When working, the movable cavity and the infusion tube are connected therein through a support frame and supported on a working table. The inner box body supports the driving motor thereon through an inner plate, and the infusion tube is movably connected therein through the movable cavity. After the infusion tube is subjected to continuous counterclockwise rotation and rolling, negative pressure is generated at the front end to extract liquid to the rear end for output.

[0008] Furthermore, a lifting handle is fixed at the top center of the support frame, and a control panel is fixed at the front side of the inner box. The support frame provides an overall lifting function through the lifting handle, and the rotation of the driving motor is controlled by the control panel.

[0010] Furthermore, a driving motor is fixed on the top of the inner plate, the rotation track of the pressure plate passes through the opening, and the pressure plate partially extends out of the opening when passing through the opening, and the driving motor fixed on the inner plate drives the turntable to rotate.

[0011] Furthermore, a convex plate is fixed on the side of the movable cavity away from the inner box body, and a fixed groove is fixed through the movable cavity behind the movable hole. The fixed groove corresponds to the opening position, and the pressure plate extending out of the opening is movably connected in the fixed groove, and the movable cavity is driven to move by pushing the convex plate.

The rear end of the delivery hose extending out of the support frame is fixedly connected with an outer screw barrel, and the end of the outer screw barrel away from the delivery hose is movably connected with a second plug. After the infusion tube fitting is subjected to continuous rolling pressure through the delivery hose, negative pressure is generated at the front end of the delivery hose to suck in liquid.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the infusion pump is prone to drug contamination when changing the drug to be transported by the drug pump by arranging an active cavity and an infusion tube fitting.
