[0003] Based on the above description, the inventors found that the existing rectal drug delivery device for general internal medicine mainly has the following disadvantages, for example: when the injection head is inserted into the rectum of the body to inject the medicinal liquid, the gas inside the body will be discharged to the anus expansion part , the rectum expands with the extrusion of the gas, so that the medicinal liquid enters the rectum to cover the inflammation site and is not absorbed in time, part of the medicinal liquid mixed with the covering will flow back into the applicator under the extrusion of the gas, resulting in partial The medicine liquid remains in the storage tube of the applicator, resulting in insufficient medicine left in the rectum for injection, and the therapeutic effect cannot be achieved

Abstract
The invention discloses a rectal administration device for general internal medicine department. The device structurally comprises an injection head, a connecting pipe, a pressing block, a pushing pipe and a storage pipe, the right end of the injection head is fixedly connected to the left end of the connecting pipe; the right end of the connecting pipe is riveted to the left end of the storage pipe; a pressing block left-end stud is connected to the right end of the push pipe; the left end of the push tube is movably clamped at the right end of the storage tube; The injection head is inserted into the liquid medicine tank, and the pressing block is pulled to drive the push tube; the injection head is inserted into the rectum from the anus; the pressing block is pushed, the jacking column abuts against the abutting plate for supporting, the liquid medicine makes contact with the elastic block, the elastic block shrinks to abut against the clamping groove and the abutting groove for supporting, the abutting groove pushes the pressing strip, and the pressing strip abuts against the pushing column at the front end of the arc plate and the clamping ring for fixing. Then, the arc plate abuts against the abutting block and the pressing plate on the inner side of the abutting column, so that the liquid medicine is completely pushed out of the storage tube to enter the rectum. By means of the structure, the situation that due to the fact that liquid medicine is left in the storage tube, part of the liquid medicine is left in the storage tube of the dosing device, the injection medicine left in the rectum is insufficient, and the treatment effect cannot be achieved is avoided.
Description
technical field [0001] The invention belongs to the treatment field of general internal medicine, and in particular relates to a rectal drug delivery device for general internal medicine. Background technique [0002] The rectum is the end of the digestive canal, which can easily cause diseases such as urethral flaccidity, appendix rectal flaccidity, anorectal flaccidity, etc. It is necessary to insert the injection head of the applicator into the rectum for treatment to make the inflammation disappear slowly. [0003] Based on the above description, the inventors found that the existing rectal drug delivery device for general internal medicine mainly has the following disadvantages, for example: when the injection head is inserted into the rectum of the body to inject medicinal liquid, the gas inside the body will be discharged to the anus expansion part , the rectum expands with the extrusion of the gas, so that the medicinal liquid enters the rectum to cover the inflammat...
