Description
技术领域technical field
本发明涉及医药器械领域，特别涉及一种新型泌尿外科用尿道给药器。The invention relates to the field of medical devices, in particular to a novel urethral drug delivery device for urology.
背景技术Background technique
由于种种原因，有的患者会发生尿路感染或泌尿系统炎症等疾病，当患者患病后，需要及时用药治疗，但口服的药物需要人身吸收后再作用于病患处，药物不能直达患处，因此治疗效果相对较慢较差。为了取得既快又好的治疗效果，当患者发生尿路感染或泌尿系统炎症等疾病时，也可对病患处直接用药，目前采用的方法是使用普通的冲洗器直接将液体药物喷洒到病患处，但是，在使用这种冲洗器治疗时，尿道内的污物很容易进入到冲洗器内，从而将药物污染，致使药物没有充分发挥药效，造成浪费，且喷洒的方式给药也不够均匀，另外，现有的给药器一般为了保持给药器在尿道压迫的情况下保持外形不变形而常采用较硬的材料，这样病人在治疗过程中由于紧张等因素会造成不适，会使给药过程变得较为麻烦。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. However, when using this irrigator for treatment, the dirt in the urethra is easy to enter into the irrigator, thereby contaminating the medicine, causing the medicine to not fully exert its efficacy, resulting in waste, and the way of spraying the drug is also unnecessary. In addition, the existing applicators generally use harder materials in order to keep the applicator from deforming under the condition of urethral compression, so that the patient will cause discomfort due to tension and other factors during the treatment process. Make the administration process more troublesome.
综上所述，现有技术中在对尿道给药时，存在尿道内污物会污染药液、给药器给病人造成不适感以及给药不均匀的问题。To sum up, in the prior art, when administering drugs to the urethra, there are problems that the dirt in the urethra will contaminate the liquid medicine, the drug delivery device will cause discomfort to the patient, and the drug administration will be uneven.
