Embodiment 1

[0056] refer to figure 1 and figure 2 , a urethral applicator for urology, mainly including the following parts:

[0057] Mixing cartridge 1, the mixing cartridge 1 is used to place medicinal liquid;

[0058] communicate with the first pipeline 11 fixed on the mixing cartridge 1;

[0059] The second pipeline 12 communicated with the first pipeline 11 and fixed through the first connection assembly 2;

[0060] a valve 121 installed on the second pipeline 12;

[0061] communicate with the drug delivery tube 13 fixed at the end of the second pipeline 12 through the second connection assembly 3;

[0062] The drug delivery assembly 4 arranged at the end of the drug delivery tube 13;

[0063] Disassemble the drug hopper 14 connected to the top of the mixing cartridge 1 through the third connection assembly 5;

[0064] The anti-foaming component 6 arranged in the mixing cartridge 1;

[0065] Micro air pump 15 for pressurization;

[0066] It is used to deliver the air pressur...

Embodiment 2

[0083] The difference from Example 1 is that the inner wall of the mixing cartridge 1 is also coated with an antifouling coating. Since the mixing cartridge 1 is used to store the medicinal solution, the medicinal solution is likely to remain in the mixing cartridge 1. It is convenient to clean the surface of the mixing cartridge 1, so a layer of antifouling coating is sprayed on the inner wall of the mixing cartridge 1, wherein the antifouling coating is prepared by the following method:

[0084] Take the following raw materials of each component by weight for later use: 50 parts of polytetrafluoroethylene, 50 parts of polypropylene, 40 parts of polyethylene, 30 parts of polycarbonate, 10 parts of polymethacrylate, 30 parts of dimethyl adipate , 20 parts of pentaerythritol, 20 parts of alkanolamide, 30 parts of diphenyl ethyl ketone, 10 parts of hydroxyethylated fatty amine, 10 parts of ethyl acetate;

[0085] S1. Prepare antifouling coating pre-preparation solution; mix and ...

Embodiment 3

[0090] The difference from Example 2 is the preparation of the antifouling coating on the inner wall of the mixing cartridge 1, wherein the antifouling coating is prepared by the following method:

[0091] Take the following components by weight for subsequent use: 55 parts of polytetrafluoroethylene, 55 parts of polypropylene, 45 parts of polyethylene, 35 parts of polycarbonate, 18 parts of polymethacrylate, 30 parts of dimethyl adipate , 20 parts of pentaerythritol, 20 parts of alkanolamide, 30 parts of diphenyl ethyl ketone, 10 parts of hydroxyethylated fatty amine, 10 parts of ethyl acetate;

[0092] S1. Prepare antifouling coating pre-preparation solution; mix and stir polytetrafluoroethylene, polypropylene, polyethylene, polycarbonate, and polymethacrylate evenly, then add it to the reaction kettle and heat it to 235°C, then keep it warm for 20min ;

[0093] S2. Preparation of antifouling coating solution: After cooling the antifouling coating pre-preparation solution o...

The key point of the technical scheme is as follows: the urethral drug delivery device comprises a drug mixing cylinder, afirst pipeline, a second pipeline, a valve, a drug delivery pipe, a drug delivery assembly, a drug hopper, an anti-foaming assembly, a miniature air pump, a pressure transmitting assembly, a locking assembly and a handheld assembly, wherein the first pipeline fixedly communicates with the drug mixing cylinder; the second pipeline fixedly communicates with the first connecting assembly through a first pipeline; the valve is mounted on the second pipeline; the drug delivery pipe fixedly communicates with the end part of the second pipeline through a second connecting assembly; the drug deliveryassembly is arranged at the end part of the drug delivery pipe; the drug hopper is detachably connected to the top end of the drug mixing cylinder through a third connecting assembly; the anti-foamingassembly is arranged in the drug mixing cylinder; the miniature air pump is used for realizing pressurization; the pressure transmitting assembly for transmitting pressure generated by the miniatureair pump into the drug mixing cylinder; the locking assembly is used for fixing the miniature air pump; and the handheld assembly can be conveniently handheld by an operator. The urethral drug delivery device has the advantages of convenience in use and high automation degree.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a urethral drug delivery device for urology. 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] You can refer to the existing Chinese patent with the publication number CN105498077A, which discloses a urethral drug delivery device for urology, including a sleeve. Injecti...
