技术领域Technical field
本发明属于医疗器械领域，特别涉及一种子宫宫腔内雾化给药装置。The invention belongs to the field of medical devices, and particularly relates to an intrauterine atomizing drug delivery device.
背景技术Background technique
子宫是胚胎着床发育的场所，孕育生命的重要器官。子宫内膜损伤致使子宫内膜容受性下降，可能造成胚胎着床失败、复发性流产导致妊娠失败，严重影响女性生殖健康，给家庭带来巨大负担和心理创伤。内膜损伤性疾病的常规治疗方法主要为通过宫腔镜手术恢复正常宫腔形态，配合雌激素药物治疗，促进内膜修复。但部分患者治疗效果不佳，研究表明宫腔灌注治疗内膜损伤性疾病，可能帮助此类患者促进内膜生长。但由于人子宫是位于骨盆腔中央的空腔器官，宫颈口较为狭小，而宫腔呈倒置三角形、较宫颈管宽大并且可能有位置、曲度的变化，目前尚没有适应子宫腔多种弧度和子宫内膜不同部位给药的器械组件，更没有宫腔内喷雾给药的雾化装置，对子宫内膜损伤性疾病的治疗具有局限性，影响局部给药的治疗效果。The uterus is the place where the embryo implants and develops, and is an important organ that nurtures life. Endometrial damage leads to decreased endometrial receptivity, which may cause embryo implantation failure and recurrent miscarriage, leading to pregnancy failure. It seriously affects female reproductive health and brings huge burden and psychological trauma to families. Conventional treatment methods for endometrial damage diseases mainly include restoring the normal uterine cavity shape through hysteroscopic surgery, combined with estrogen drug treatment to promote endometrial repair. However, some patients have poor treatment results. Studies have shown that intrauterine infusion to treat endometrial injury diseases may help such patients promote endometrial growth. However, because the human uterus is a hollow organ located in the center of the pelvic cavity, the cervical opening is relatively narrow, and the uterine cavity is in the shape of an inverted triangle, wider than the cervical canal, and may have changes in position and curvature. Currently, it has not been adapted to the various curvatures and curvatures of the uterine cavity. There are device components for drug delivery in different parts of the endometrium, and there is no atomization device for intrauterine spray drug delivery, which has limitations in the treatment of endometrial damage diseases and affects the therapeutic effect of local drug delivery.
因此，为了解决上述问题，本发明提供了一种能给子宫内膜不同部位雾化给药，以及多种弧度变化雾化给药的装置，本发明不仅打破了现有子宫内膜疾病治疗的局限性，还提高了治疗效果。Therefore, in order to solve the above problems, the present invention provides a device that can atomize drug administration to different parts of the endometrium and atomize drug administration with various arc changes.

图2示出了图1的剖面图。如图2所示，在一些实施例中，还包括清除结构5，所述清除结构5包括通气软管51、气囊52，所述通气软管51设在硬管21与形变软管22的内壁上，所述通气软管51穿过硬管21向外延伸的一端设有气囊52，所述通气软管51远离气囊52的一端与固定块41连通；清除结构5能清除子宫内膜上的粘液，有助于雾化药物粘附在子宫内膜上；其中，人为不断地捏气囊52，可使气流通过通气软管51进入宫腔内，不断喷出的气流可清除宫腔黏膜上的一些粘液，有助于药物粘在宫腔壁疾病处。FIG. 2 shows a cross-sectional view of FIG. 1 . As shown in Figure 2, in some embodiments, a cleaning structure 5 is also included. The cleaning structure 5 includes a ventilation hose 51 and an air bag 52. The ventilation hose 51 is provided on the inner walls of the hard tube 21 and the deformation hose 22. On the upper body, one end of the ventilation hose 51 extending outward through the hard tube 21 is provided with an air bag 52, and one end of the ventilation hose 51 away from the air bag 52 is connected to the fixed block 41; the cleaning structure 5 can clear the mucus on the endometrium. , which helps the atomized medicine to adhere to the endometrium; among them, manually pinching the air bag 52 continuously allows the airflow to enter the uterine cavity through the ventilation hose 51, and the continuous airflow can clear some of the uterine cavity mucosa. Mucus helps the medicine stick to the diseased uterine wall.
具体的，注射器1卡设在硬管21内，便于医护人员拆卸安装注射器1，提高治疗效率。Specifically, the syringe 1 is stuck in the hard tube 21, which facilitates the medical staff to disassemble and install the syringe 1 and improves the treatment efficiency.
在一些实施例中，所述固定块41上设有贯穿自身的通气块43，所述通气块43上设有若干个通气孔431，所述通气块43与通气软管51连通，所述通气块43延伸出固定块41的部位呈圆锥形；若干个通气孔431能对气流增压，以便快速清除子宫内膜处的粘液；圆锥形的通气块43所清除的范围较大，增加了清除效率。In some embodiments, the fixed block 41 is provided with a ventilation block 43 that runs through itself. The ventilation block 43 is provided with several ventilation holes 431 . The ventilation block 43 is connected to the ventilation hose 51 . The ventilation block 43 is connected with the ventilation hose 51 . The part of the block 43 extending out of the fixed block 41 is conical; several ventilation holes 431 can pressurize the air flow to quickly remove the mucus in the endometrium; the conical ventilation block 43 has a larger cleaning range, which increases the removal time. efficiency.
在一些实施例中，所述形变管2靠近注射器1的部位设有手持壳23；便于人为手持，提高了便捷性。In some embodiments, the deformation tube 2 is provided with a hand-held shell 23 near the syringe 1, which facilitates manual hand-holding and improves convenience.
子宫宫腔内雾化给药装置的工作原理如下：The working principle of the intrauterine aerosol drug delivery device is as follows:
通过弧度可多变的给药结构，满足多种弧度变化雾化给药的要求。其中，必要时，手持导管6的手柄61，并将导管6的支撑管62依次塞入硬管21与形变软管22内，并带着形变软管22进入子宫宫腔内，待形变软管22进入子宫宫腔内后，将导管6取出，此时，一只手握住手持壳23，另一只手向外扯转动盘333，使卡环3331脱离卡槽312，伸缩块34脱离复位槽338，限制块35卡在限制槽337内，再转动转动杆334收放收放线335，调整形变软管22的弧度变化，待调整好后，对转动盘333方向施力，使限制块35脱离限制槽337，同事卡环3331卡入卡槽312，伸缩块34远离转动盘333的一端卡入复位槽338内，再利用空余的手不断地捏气囊52，使气流从通气孔431喷出，以此快速清除子宫内膜处的粘液，再将注射器1卡在硬管21内，用空余的手推动注射器1，使注射器1中的药物流入到硬管21与形变软管22中，因药物具有压力，所以药物通过若干个雾化孔421时会再次增压，实现雾化，再者，雾化块42的端面为斜端面，与雾化块42端面对应的子宫内膜都会粘黏上药物，增加了药物的扩散面积，也使药物直达了不角度的疾病位置，实现了有效的药物递送。给药结构不仅现有子宫内膜疾病治疗的局限性，还提高了治疗效果。Through the drug delivery structure with variable curvature, it can meet the requirements of atomized drug delivery with various curvature changes. Wherein, if necessary, hold the handle 61 of the catheter 6, insert the support tube 62 of the catheter 6 into the hard tube 21 and the deformation hose 22 in sequence, and take the deformation hose 22 into the uterine cavity, and wait for the deformation hose to 22 enters the uterine cavity, take out the catheter 6. At this time, hold the handheld shell 23 with one hand, and pull the rotating disk 333 outward with the other hand, so that the snap ring 3331 is detached from the slot 312, and the telescopic block 34 is detached from the reset position. slot 338, the limiting block 35 is stuck in the limiting slot 337, and then rotate the rotating rod 334 to retract and release the retracting line 335, and adjust the curvature change of the deformation hose 22. After the adjustment is completed, apply force in the direction of the rotating disk 333, so that the limiting block 35 is out of the restriction slot 337, and the snap ring 3331 is stuck into the slot 312, and the end of the telescopic block 34 away from the rotating disk 333 is stuck into the reset slot 338, and then use your free hand to continuously pinch the airbag 52 to make the air flow spray from the ventilation hole 431. to quickly remove the mucus in the endometrium, then place the syringe 1 in the hard tube 21, push the syringe 1 with your free hand, so that the medicine in the syringe 1 flows into the hard tube 21 and the deformable flexible tube 22. Because the medicine has pressure, it will be pressurized again when it passes through several atomization holes 421 to achieve atomization. Furthermore, the end face of the atomization block 42 is a bevel end face, and the endometrium corresponding to the end face of the atomization block 42 will be sticky. Adhering to the drug increases the diffusion area of the drug and allows the drug to reach the disease location at any angle, achieving effective drug delivery. The drug delivery structure not only limits the existing treatment of endometrial diseases, but also improves the therapeutic effect.
具体的，在临床应用中，需要与腹部超声配合。Specifically, in clinical application, it needs to be coordinated with abdominal ultrasound.
具体的，需要放收放线335时，往反方向转动转动杆334即可。Specifically, when it is necessary to release the retracting and releasing line 335, just rotate the rotating rod 334 in the opposite direction.
