Problems solved by technology

However, the cost of the operation is high, not to mention the pain, and it also affects the normal working time. The most fundamental thing is that it cannot solve the problem fundamentally, but only treats the symptoms and not the root cause.

Embodiment 1

[0037] See figure 1 , the prostate drug delivery device of this embodiment includes an elastic tubular body 1 .

[0038] The elastic tubular body 1 is made of silica gel or natural latex, the length is not less than 20cm, preferably 20-30cm, and the static diameter is 3-6mm. The front and rear ends of the elastic tubular body 1 are closed. Two thin-wall sections 12 are provided on the front wall of the elastic tubular body 1 , and at least one small hole 13 is provided on the tube wall between the two thin-wall sections 12 .

[0039] The length of the thin-walled section 12 at the front of the elastic tubular body 1 along the central axis of the elastic tubular body 1 is smaller than the length of the thin-walled section 12 at the rear along the central axis of the elastic tubular body 1 .

[0040] The method of using the prostate drug delivery device of this embodiment is: after lubricating the elastic tubular body 1, insert it from behind the urethra, and stop when the fro...

Embodiment 2

[0042] See figure 2 , This embodiment is basically the same as Embodiment 1, except that the rear end of the elastic tubular body 1 is an open structure.

[0043] The usage method of this embodiment is basically the same as the usage method of Embodiment 1, the difference is that the needle cylinder does not need to be provided with a needle, but directly fits with the opening of the rear end of the elastic tubular body 1 .

Embodiment 3

[0045] See image 3 , this embodiment is basically the same as Embodiment 1, except that: the rear end of the elastic tubular body 1 is an open structure, and a valve or a plug 14 is provided in the opening. The valve opens automatically when an object is inserted and closes automatically when the object is pulled out.

[0046] The usage method of this embodiment is basically the same as the usage method of Embodiment 1, the difference is that: when the plug is set in the opening, the syringe needs to be equipped with a needle, but when the needle is pulled out, it does not need to be clamped with a clip or squeezed by hand ;

[0047]When a valve is provided in the opening, the syringe does not need to be provided with a needle, but directly cooperates with the opening at the rear end of the elastic tubular body 1, and the syringe does not need to be clamped or squeezed by hand when the syringe is pulled out.

Abstract

The invention discloses a prostate administration apparatus, which comprises an elastic tubular main body, wherein the front end of the elastic tubular main body is closed; two thin-wall sections are arranged on the front tube wall of the elastic tubular main body; and at least one small hole is formed in a tube wall between the two thin-wall sections. When the prostate administration apparatus provided by the invention is used, two thin-wall sections of the elastic tubular main body get expanded and protruded firstly, and then medicine liquid is injected into the inner hole of the elastic tubular main body; and the medicine liquid, under pressure, is just permitted to flow from the small hole between the two thin-wall sections and then the medicine liquid enters a prostate and directly reaches a focus, so that a therapeutic effect can be achieved instantly.

Description

technical field [0001] The invention relates to a prostate drug delivery device. Background technique [0002] The special position and structure of the prostate determine that simple drug treatment is ineffective. Its outer layer has a lipid envelope, which is a barrier for drugs. It is difficult for general drugs to reach the local area, and the drug effect and curative effect cannot be achieved. Layers of barriers are required to reach the lesion, but the efficacy of the drug is running out, so the effect is extremely slow and inefficient, and clinical application of these methods can only improve the curative effect. Regarding the lipid envelope of prostatitis, many antibiotics are helpless against chronic prostatitis. Although antibiotics can quickly remove the urinary tract symptoms caused by prostatitis, they only treat the symptoms but not the root cause. The prostate has a unique anatomical location and physiological structure. The most important feature is that i...
