Drawing positive pressure type medical infusion device connected with extracorporeal indwelling catheter

Abstract

The drawing positive pressure type medical infusion device comprises a lower rod body, a rocker is arranged on the front face of the lower rod body, a base is fixedly installed in the lower rod body, an upper rod body is slidably connected to the top of the lower rod body, and a hook is fixedly connected to the top end of the upper rod body; and the lifting assembly is arranged in the lower rod body, the lifting assembly comprises a gearbox, limiting columns, a transmission lead screw and a fixing base, the bottom ends of the two limiting columns are fixedly connected with the top end of the base, sliding grooves are formed in the sides, close to each other, of the two limiting columns, and first sliding blocks are slidably connected into the two sliding grooves. The infusion support has the advantages that the height of the upper rod body can be adjusted when a patient moves, the situation that an extension tube is too long and then knocked off is avoided, the situation that an infusion bottle shakes and collides with the infusion support to be broken during moving is avoided, the safety of the patient is guaranteed, the infusion support is smoother during ascending or descending, and the patient can operate the infusion support more easily.

Description

technical field [0001] The invention relates to an infusion device, in particular to a pulling positive pressure medical infusion device connected with an indwelling catheter outside the body, and belongs to the field of medical technology. Background technique [0002] When the patient needs multiple infusions, indwelling catheters are usually used in vitro. The connections between the indwelling catheters and the infusion set are divided into needle connection and needleless connection, and then the infusion bottle during infusion is generally placed on the hook of the infusion stand. Above, the liquid flows out from the infusion bottle, passes through the positive pressure valve, and enters the extension tube, and the liquid in the extension tube enters the patient's body through the catheter. [0003] Most of the existing infusion stand heights are fixed. When the patient is lying on the bed, in order to facilitate the infusion, the extension tube will be set very long, ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing infusion stand heights are fixed. When the patient is lying on the bed, in order to facilitate the infusion, the extension tube will be set very long, but when the patient needs to get up and move or go to the toilet, the extension tube will be pulled The extension tube is too long, and sometimes it will touch the extension tube accidentally, or even knock it off. Because the extension tube is too long, it becomes a burden at this time. When the patient is walking, the infusion bottle will keep shaking, which may cause After colliding with the infusion stand, the infusion bottle is smashed, which will bring certain dangers to the patient and others. When lying down and resting, the hooks at both ends may block the walking of others and cause trouble to others.
