Problems solved by technology

[0004] 1) Due to the single point of washing, the effect of single washing is poor, and it usually needs to be washed more than 3 times repeatedly to produce obvious therapeutic effect;
[0005] 2) When flushing, the waste liquid flowing out from the vaginal opening will be sprinkled on the ground and hands, which brings great inconvenience;
[0006] 3) The medicinal liquid washed into the body cannot be retained, resulting in poor medicinal effect

Embodiment 1

[0040]A drug delivery device for the urinary system, comprising a catheter 1, the left end of the catheter 1 is externally threaded with an end cap 2, and a plurality of liquid outlet holes 201 are annularly arranged on the right end surface of the end cap 2, and the end cap The left side of 2 has a spherical introduction surface 202; the inside of the end cap 2 has an inner cavity 203 communicating with the conduit 1 and the outlet hole 201; a slide tube 3 is arranged outside the conduit 1, The slide tube 3 can slide along the axial direction of the guide tube 1, or can rotate coaxially along the guide tube 1; a stepped hole 301 is provided at the left end of the slide tube 3, and a stepped hole 301 is arranged in the stepped hole A sealing gasket 302 is embedded in the inner hole wall of 301, and the sealing gasket 302 forms a seal after contacting the outer wall of the conduit 1, and a tapered sealing cup 4 is assembled on the outside of the sliding tube 3, so that The diam...

Embodiment 2

[0042] A frustum-shaped splitter end 211 is provided at the axial end surface of the inner cavity 203, the diameter of the splitter end 211 gradually decreases toward the direction of the catheter 1, and the diverter end 211 and the left end of the catheter 1 A gap is formed between the openings, and after the piston rod 5 is fully pushed in to the left, a gap remains between the end 501 and the end surface of the splitter end 211 .

Embodiment 3

[0044] The thickness of the sealing gasket 302 gradually decreases from the outside to the center; so as to reduce the resistance when the sliding tube 3 slides along the axial direction of the guide tube 1 .

Abstract

The invention discloses a urinary system dosing device which comprises a catheter, an end cover is in external threaded connection with the left end of the catheter, a plurality of liquid outlet holes are annularly formed in the end face of the right side of the end cover, and a spherical leading-in surface is arranged on the left side of the end cover; an inner cavity communicated with the guide pipe and the liquid outlet hole is formed in the end cover; a sliding pipe is arranged outside the guide pipe, and the sliding pipe can slide in the axial direction of the guide pipe and can also coaxially rotate along the guide pipe. A stepped hole is formed in the left end of the sliding pipe; and the device can achieve comprehensive flushing, can effectively treat waste liquid, and can also realize retention and soaking.

Description

technical field [0001] The invention relates to a urinary system drug delivery device. Background technique [0002] Due to various reasons, some patients may develop diseases such as urinary tract infection or urinary system inflammation. When the patient is sick, he needs to be treated with medication in time, but the oral medicine needs to be absorbed by the body before acting on the affected area. The drug cannot reach the affected area directly. Therefore, the therapeutic effect is relatively slow and poor. In order to obtain fast and good therapeutic effect, when the patient develops diseases such as urinary tract infection or urinary system inflammation, the medicine can also be directly applied to the affected area. affected area. [0003] However, the above steps have the following disadvantages in operation: [0004] 1) Due to the single point of washing, the effect of single washing is poor, and it usually needs to be washed more than 3 times repeatedly to prod...
