DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] See also Figure 1-5As shown, in this embodiment, a cleaning drug delivery device for anorectal use is provided, comprising: a barrel 1, a barrel cover 2 and an extrusion plate 6, a drug delivery tube 3 is arranged on one side of the barrel 1, a drug delivery head 4 is rotatably matched on the drug delivery tube 3, an impeller 16 connected to the drug delivery head 4 is arranged in the drug delivery tube 3, and an automatic blocking component 13 matched with the drug delivery tube 3 is arranged in the side wall of the barrel 1;

[0032] A mounting member 8 is provided between the cylinder cover 2 and the cylinder body 1, and the cylinder cover 2 is assembled and disassembled on the cylinder body 1 through the mounting member 8;

[0033] The extrusion disk 6 is located on the inner side of the cylinder cover 2, a tension spring 7 is arranged between the extrusion disk 6 and the cylinder cover 2, a retractable assembly 10 connected to the extrusion disk 6 is arranged in the side wall of the cylinder cover 2, the cylinder cover 2 moves on the inner side of the cylinder body 1 through the retractable assembly 10, and a knob 5 that cooperates with the retractable assembly 10 for transmission is rotatably arranged on one side of the cylinder cover 2.

[0034] The application of one aspect of the present embodiment is as follows: when it is necessary to apply medicine to the anorectal affected area of ​​the patient for cleaning, the medicine is first placed in the cylinder 1, the cylinder cover 2 is installed on the cylinder 1 through the mounting member 8, and then the drug delivery head 4 is pushed into the patient's anorectal area, and then the knob 5 is turned. The rotation of the knob 5 drives the retractable assembly 10 to operate, and the operation of the retractable assembly 10 loosens the extrusion disk 6, and the extrusion disk 6 moves inside the cylinder 1 to extrude the medicine through the elastic force of the tension spring 7. The extruded medicine passes through the automatic blocking assembly 13 in the drug guide tube 3. The automatic blocking assembly 13 is squeezed to cancel the blocking of the drug guide tube 3, and the medicine in the drug guide tube 3 is squeezed out by the drug delivery head 4. When the medicine moves in the drug guide tube 3, the impeller 16 is driven to operate, and the drug delivery head 4 drives the drug delivery head 4 to rotate at the end of the drug guide tube 3, so that the drug delivery head 4 can rotate during the drug delivery process to evenly extrude the medicine on the affected area. After the drug application is completed, the cylinder 1 is taken out to the outside.

[0035] By means of the retractable assembly 10 provided on the barrel cover 2, when it is necessary to squeeze the medicine out of the barrel body 1, the knob 5 is turned to retract and release the extrusion disk 6 through the retractable assembly 10, and the extrusion disk 6 moves inside the barrel body 1 through the elastic force of the tension spring 7 to squeeze the medicine, and the squeezed medicine is squeezed out by the drug delivery head 4 through the drug guide tube 3, thereby reducing the situation where the direct extrusion force is difficult to control and causes the waste of medicine, thereby facilitating the control of the drug delivery amount; by means of the automatic blocking assembly 13 provided in the barrel body 1, when it is not necessary to squeeze the medicine out of the barrel body 1, the automatic blocking assembly 13 automatically blocks the drug guide tube 3, thereby reducing the situation where the external gas enters the barrel body 1 and causes bacterial contamination of the medicine; by means of the impeller member 16 provided in the drug guide tube 3, when the medicine moves in the drug guide tube 3, the impeller member 16 is driven to operate, so that the drug delivery head 4 can rotate at the end of the drug guide tube 3, thereby facilitating the uniform extrusion of the medicine into the affected area.

[0036] like Figure 2As shown, an inner cavity 9 is provided in the side wall of the cylinder cover 2 of this embodiment;

[0037] like Figure 2-3 As shown, specifically, the specific structure of the retractable assembly 10 includes the following: a rotating rod 1001 rotatably engaged in the inner cavity 9 and transmittingly engaged with the knob 5, a rope winding drum 1002 installed on the peripheral side of the rotating rod 1001, and a pull rope 1003 sleeved on the rope winding drum 1002 and fixedly connected to one side of the extrusion disk 6; a worm wheel 11 is installed on the peripheral side of the rotating rod 1001, and a worm 12 meshing with the worm wheel 11 is rotatably engaged on one side of the inner cavity 9, and the knob 5 is installed at the end of the worm 12 that passes through the cylinder cover 2, wherein the extrusion disk 6 can be stably moved in the cylinder body 1 through the self-locking property of the worm 12 and the worm wheel 11.

[0038] When it is necessary to squeeze the medicine out of the barrel 1, turn the knob 5. The rotation of the knob 5 drives the worm 12 to rotate. The rotation of the worm 12 drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 drives the rotating rod 1001 to rotate. The rotation of the rotating rod 1001 drives the rope reel 1002 to rotate. The rotation of the rope reel 1002 can loosen the pull rope 1003. The loose pull rope 1003 can make the extrusion disk 6 move inside the barrel 1 through the elastic force of the tension spring 7 to squeeze the medicine. The squeezed medicine is squeezed out by the drug delivery head 4 through the drug guiding tube 3, thereby reducing the situation where it is difficult to control the direct extrusion force and cause the waste of medicine, thereby facilitating the control of the amount of medicine administered.

[0039] like Figure 4 As shown, a through hole corresponding to the drug guiding tube 3 is opened on one side of the barrel 1 of this embodiment, and the automatic blocking component 13 is located in the through hole;

[0044] When the drug moves in the drug guiding tube 3, the flow of the drug in the drug guiding tube 3 drives the blade wheel 1602 to rotate, and the rotation of the blade wheel 1602 drives the connecting rod 1601 to rotate. The rotation of the connecting rod 1601 drives the dosing barrel 402 to rotate at the end of the drug guiding tube 3 through the bearing 15. The drug in the dosing barrel 402 is squeezed out from the multiple dosing holes 403, which can make the dosing head 4 rotate during the dosing process, so that the drug can be evenly squeezed onto the affected area.

[0045] like Figure 2 As shown, specifically, the specific structure of the mounting member 8 includes: an external thread 801 disposed on the outside of the cylinder body 1, and an internal thread 802 disposed on the inside of the cylinder cover 2 and meshing with the external thread 801;
