Medical screw propelling type enema device

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a medical screw propelling type enema device. The medical screw propelling type enema device comprises a discharging tube, a cleaning guide head, an infusion tube and a discharging tube fixing mechanism. A spiral positioning mechanism is mounted in the head end of the discharging tube, a spiral driving mechanism is mounted at the tail end of the discharging tube and comprises a support I and a driving wheel, the support I is mounted on the inner wall of the tail end of the discharging tube, and the driving wheel is rotationally mounted on the support I. One end of the infusion tube is coiled in the discharging tube and then penetrates the spiral positioning mechanism to be connected to the cleaning guide head, the inner wall of the discharging tube is provided with a notch for limiting the infusion tube, and the discharging tube fixing mechanism sleeves the discharging tube. The medical screw propelling type enema device has advantages that structural simplicity and convenience in operation are realized, injuries to human bodies are avoided, the whole large intestine can be cleaned, high efficiency and high speed in intestinal cleaning are realized, and the intestinal tract is protected in a cleaning process, and retention enema therapy of high-position colons can be realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical screw propulsion enema device. Background technique [0002] Due to the need for intestinal preparation before colonoscopy, and there are certain defects in intestinal preparation with drugs, it is necessary to use an enema tube; the currently used enema tube is basically inserted into the intestinal tract with manual assistance. Artificial assistance cannot effectively overcome the obstruction of the natural curvature of the intestinal tract to reach the high colon, so that the intestinal preparation is often insufficient. [0003] For example, a self-propelled enema pipe with authorization notification number CN102500008B includes a slag discharge pipe, and a water delivery hose is coiled inside the slag discharge pipe, and one end of the water delivery hose passes through the tail of the slag discharge pipe. The pipe wall at the end is connected to the water...

[0002] Due to the need for intestinal preparation before colonoscopy, and there are certain defects in intestinal preparation with drugs, it is necessary to use an enema tube; the currently used enema tube is basically inserted into the intestinal tract with manual assistance. Artificial assistance cannot effectively overcome the obstruction of the natural curvature of the intestinal tract to reach the high colon, so that the intestinal preparation is often insufficient. After the intestinal preparation, the field of view of the colonoscopy is not well exposed, and it is impossible to perform retention enema treatment for high colonic lesions

Although this solution can clean the intestinal tract to make the intestinal tract fully prepared, there are still the following problems: (1) Although the use of the reacti
