背景技术Background technique

产前诊断是指在出生前对胚胎或胎儿的发育状态、是否患有疾病等方面进行检测诊断，从而掌握先机，对可治性疾病，选择适当时机进行宫内治疗；对于不可治疗性疾病，能够做到知情选择，广义的产前诊断对象包括：反复早孕期自然流产；既往出生缺陷病史；家族分子遗传病史；神经管缺陷家族史；妊娠合并1型糖尿病、高血压、癫痫、哮喘；曾暴露于药物、病毒、环境危害；父母近亲等方面。Prenatal diagnosis refers to detecting and diagnosing the developmental status of embryos or fetuses and whether they suffer from diseases before birth, so as to grasp the opportunities and choose the appropriate time for intrauterine treatment for treatable diseases; for intractable diseases , able to make informed choices, the broad prenatal diagnosis objects include: recurrent spontaneous abortion during early pregnancy; previous history of birth defects; family history of molecular genetic disease; family history of neural tube defects; pregnancy complicated withtype 1 diabetes, hypertension, epilepsy, asthma; Have been exposed to drugs, viruses, environmental hazards; close relatives of parents, etc.

在众多产前诊断的种类中脐带血管穿刺是十分重要的一种，通过脐带血管穿刺可以提取胎儿的细胞，用于胎儿的细胞检测。Among the many types of prenatal diagnosis, umbilical cord puncture is a very important one. Fetal cells can be extracted through umbilical cord puncture for fetal cell detection.

在孕妇进行脐带血管穿刺时，为了孕妇腹部大幅度波动，医生会要求孕妇进行胸式呼吸，以免腹中胎儿出现起伏波动，导致插针插入到胎儿脐带出现异常，既插针脱离或穿过脐带，但在穿刺过程中，孕妇难免会出现紧张情绪，在无意识的条件下，孕妇便会大口喘气，进行腹式呼吸，对穿刺的进行造成影响。When a pregnant woman performs umbilical cord puncture, the doctor will ask the pregnant woman to perform thoracic breathing for the large fluctuation of the pregnant woman's abdomen, so as to avoid the fluctuation of the fetus in the abdomen, resulting in abnormal insertion of the needle into the umbilical cord of the fetus. However, during the puncture process, the pregnant woman will inevitably feel nervous. Under the condition of unconsciousness, the pregnant woman will gasp for breath and perform abdominal breathing, which will affect the puncture.

(三)有益效果(3) Beneficial effects

与现有技术相比，本发明提供了一种高效的产前诊断间期胎儿细胞检测装置，具备以下有益效果：Compared with the prior art, the present invention provides an efficient prenatal diagnosis interphase fetal cell detection device, which has the following beneficial effects:

1、该高效的产前诊断间期胎儿细胞检测装置，通过吸盘与承接杆的配合使用，在对孕妇进行脐带血管穿刺时，将现将插针穿过孕妇腹腔，随后穿过羊水膜，最后插入到胎儿的脐带内，为了防止抖动，将抽液管固定。在插针插入到脐带内后，调整移动杆使其在承接管内部挤压缓冲杆，并越过缓冲杆相对于承接管移动，使得移动杆底部的吸盘吸住孕妇的腹部且无挤压力作用。当孕妇未进行腹式呼吸时，腹部波动幅度较小，腹部内的胎儿不会出现移动，医生只需拉动抽液杆，通过抽液板将脐带内的血液抽入到抽液管内即可，当孕妇由于紧张无意识进行腹式呼吸时，腹部出现剧烈的波动，吸盘随着波动而起伏，进而通过移动杆带动承接管同步移动，导致承接管上方的承接管同步移动，当承接杆相对于抽液管向上移动时，其侧面设置的凹形块的斜面对顶杆产生挤压，使其相对于气管移动，将气管内气体挤压进空气弹簧内。空气弹簧由于内部气压力增大导致弹力增大，对连接杆进行挤压，使插针侧面设置用于固定插针的弹簧杆越过单向卡块，故连接杆带动插针相对于抽液管同步移动，导致插针随腹部向上波动而上移，由于腹部的胎儿会同样出现向上波动，因此插针不会脱离或穿过脐带。同理，当腹部向下剧烈波动时，插针同样会同步移动，从而达到了在孕妇进行腹式呼吸时，自动调整插针深度，防止插针脱离或穿过脐带的效果。1. This high-efficiency prenatal diagnosis interphase fetal cell detection device is used in conjunction with the suction cup and the receiving rod. When the umbilical cord blood vessel is punctured in the pregnant woman, the needle will be passed through the abdominal cavity of the pregnant woman, then through the amniotic membrane, and finally. Inserted into the umbilical cord of the fetus, in order to prevent shaking, the suction tube is fixed. After the insertion needle is inserted into the umbilical cord, adjust the moving rod to squeeze the buffer rod inside the receiving tube, and move relative to the receiving tube over the buffer rod, so that the suction cup at the bottom of the moving rod sucks the abdomen of the pregnant woman without pressing force . When the pregnant woman does not perform abdominal breathing, the fluctuation of the abdomen is small, and the fetus in the abdomen will not move. The doctor only needs to pull the suction rod and draw the blood in the umbilical cord into the suction tube through the suction plate. When pregnant women perform abdominal breathing unconsciously due to tension, the abdomen fluctuates violently, the suction cup rises and falls with the fluctuations, and then drives the receiving pipe to move synchronously through the moving rod, causing the receiving pipe above the receiving pipe to move synchronously. When the liquid pipe moves upward, the slope of the concave block arranged on the side thereof squeezes the ejector rod, so that it moves relative to the trachea and squeezes the gas in the trachea into the air spring. The elastic force of the air spring increases due to the increase of the internal air pressure, and the connecting rod is squeezed, so that the spring rod set on the side of the pin for fixing the pin crosses the one-way block, so the connecting rod drives the pin relative to the suction tube. The synchronized movements cause the pins to move up as the abdomen undulates, and since the fetus in the abdomen will also oscillate upwards, the pins will not come off or pass through the umbilical cord. Similarly, when the abdomen fluctuates violently downward, the needle will also move synchronously, thus achieving the effect of automatically adjusting the depth of the needle when pregnant women perform abdominal breathing, preventing the needle from falling off or passing through the umbilical cord.

2、该高效的产前诊断间期胎儿细胞检测装置，通过承接轮与连动杆的配合使用，在承接管相对于承接轮移动时，承接轮被带动，进而将连动杆带动，由于腹部出现剧烈波动，故连动杆的移动距离较大，在连动杆移动时，T形杆在侧面设置的支杆的作用下反向移动，通过其侧面设置的弧形凸起对卡杆造成挤压，使卡杆向靠近抽液杆方向移动，插入到抽液杆侧面开设的插孔内，将抽液杆卡死，防止在腹部波动时抽液管继续抽液，从而达到了避免插针在脐带移动时抽液，防止靠近脐带内壁对脐带产生较大液压力，进而损伤脐带的效果。2. The high-efficiency prenatal diagnosis interphase fetal cell detection device is used in conjunction with the receiving wheel and the connecting rod. When the receiving pipe moves relative to the receiving wheel, the receiving wheel is driven, and then the connecting rod is driven. Severe fluctuations occur, so the moving distance of the linkage rod is large. When the linkage rod moves, the T-shaped rod moves in the opposite direction under the action of the support rod set on the side, and the arc protrusion set on the side of the T-shaped rod causes the clamping rod. Squeeze, move the clamping rod toward the direction close to the suction rod, insert it into the hole opened on the side of the suction rod, and lock the suction rod to prevent the suction tube from continuing to pump liquid when the abdomen fluctuates, thus avoiding insertion. The needle draws fluid when the umbilical cord moves, preventing the effect of being close to the inner wall of the umbilical cord from generating a large hydraulic pressure on the umbilical cord, thereby damaging the umbilical cord.

3、该高效的产前诊断间期胎儿细胞检测装置，通过风箱与螺杆的配合使用，在承接杆相对于抽液管移动时，螺杆与承接杆发生啮合传动，使得螺杆转动，又螺杆与吹气杆啮合连接，故吹气杆转动，带动下方的吹气扇转动，吹气扇产生的气流通过风箱喷出，而风箱的出口设置在插针的边缘，故插针的表面会产生向下的气流。在插针自动调整深度时，会与孕妇腹腔产生相对位移，而孕妇腹腔的起伏波动是成椭圆状的，因此插针会与腹腔产生横向挤压力，极有可能在挤压力作用下插针与腹腔的连接处出现消毒液渗入到腹腔内的现象出现，而沿插针侧面的气流会将插针与腹腔连接处的消毒液吹散，从而达到了防止在孕妇腹式呼吸时，消毒液渗入到腹腔内部的效果。3. This high-efficiency prenatal diagnosis interphase fetal cell detection device is used in conjunction with the bellows and the screw. When the receiving rod moves relative to the suction tube, the screw and the receiving rod engage and drive, so that the screw rotates, and the screw and the blower are connected. The air rod is meshed and connected, so the air rod rotates, which drives the blowing fan below to rotate, and the airflow generated by the blowing fan is ejected through the bellows, and the outlet of the bellows is set at the edge of the pin, so the surface of the pin will produce downward pressure. air flow. When the depth of the insertion needle is automatically adjusted, it will have a relative displacement with the abdominal cavity of the pregnant woman, and the fluctuation of the abdominal cavity of the pregnant woman is elliptical, so the insertion needle will generate a lateral extrusion force with the abdominal cavity, and it is very likely that the insertion needle will be inserted under the action of the extrusion force. At the connection between the needle and the abdominal cavity, the disinfectant seeps into the abdominal cavity, and the airflow along the side of the needle will blow away the disinfectant at the connection between the needle and the abdominal cavity, thus preventing the sterilization during abdominal breathing of pregnant women. The effect of fluid infiltration into the abdominal cavity.

在对孕妇进行脐带血管穿刺时，将现将插针3穿过孕妇腹腔，随后穿过羊水膜，最后插入到胎儿的脐带内，为了防止抖动，将抽液管1固定。When puncturing the umbilical cord blood vessels of a pregnant woman, theneedle 3 is inserted through the abdominal cavity of the pregnant woman, then through the amniotic membrane, and finally inserted into the umbilical cord of the fetus. In order to prevent shaking, thesuction tube 1 is fixed.

在插针3插入到脐带内后，调整移动杆13使其在承接管6内部挤压缓冲杆12，并越过缓冲杆12相对于承接管6移动，使得移动杆13底部的吸盘14吸住孕妇的腹部且无挤压力作用。After theneedle 3 is inserted into the umbilical cord, the movingrod 13 is adjusted to squeeze thebuffer rod 12 inside the receivingtube 6, and move over thebuffer rod 12 relative to the receivingtube 6, so that thesuction cup 14 at the bottom of the movingrod 13 sucks the pregnant woman the abdomen without the effect of squeezing force.

当孕妇未进行腹式呼吸时，腹部波动幅度较小，腹部内的胎儿不会出现移动，医生只需拉动抽液杆4，通过抽液板2将脐带内的血液抽入到抽液管1内即可，当孕妇由于紧张无意识进行腹式呼吸时，腹部出现剧烈的波动，吸盘14随着波动而起伏，进而通过移动杆13带动承接管6同步移动，导致承接管6上方的承接管6同步移动，当承接杆5相对于抽液管1向上移动时，其侧面设置的凹形块的斜面对顶杆18产生挤压，使其相对于气管19移动，将气管19内气体挤压进空气弹簧20内。When the pregnant woman does not perform abdominal breathing, the fluctuation of the abdomen is small, and the fetus in the abdomen will not move. The doctor only needs to pull thesuction rod 4, and the blood in the umbilical cord is drawn into thesuction tube 1 through thesuction plate 2. When the pregnant woman performs abdominal breathing unconsciously due to tension, the abdomen will fluctuate violently, and thesuction cup 14 will rise and fall with the fluctuation, and then the movingrod 13 will drive the receivingpipe 6 to move synchronously, resulting in the receivingpipe 6 above the receivingpipe 6. Synchronous movement, when the receivingrod 5 moves upward relative to thesuction pipe 1, the slope of the concave block provided on the side thereof squeezes theejector rod 18, so that it moves relative to thetrachea 19, and the gas in thetrachea 19 is squeezed into the Inside theair spring 20.

空气弹簧20由于内部气压力增大导致弹力增大，对连接杆21进行挤压，使插针3侧面设置用于固定插针3的弹簧杆22越过单向卡块23，故连接杆21带动插针3相对于抽液管1同步移动，导致插针3随腹部向上波动而上移，由于腹部的胎儿会同样出现向上波动，因此插针3不会脱离或穿过脐带。The elastic force of theair spring 20 increases due to the increase of the internal air pressure, and squeezes the connecting rod 21, so that thespring rod 22 provided on the side of thepin 3 for fixing thepin 3 crosses the one-way block 23, so the connecting rod 21 drives the Theneedle 3 moves synchronously relative to thesuction tube 1, causing theneedle 3 to move upward with the upward fluctuation of the abdomen. Since the fetus in the abdomen will also fluctuate upward, theneedle 3 will not detach or pass through the umbilical cord.

同理，当腹部向下剧烈波动时，插针3同样会同步移动，从而达到了在孕妇进行腹式呼吸时，自动调整插针3深度，防止插针3脱离或穿过脐带的效果。Similarly, when the abdomen fluctuates violently downward, theneedle 3 will also move synchronously, thus achieving the effect of automatically adjusting the depth of theneedle 3 when the pregnant woman performs abdominal breathing, preventing theneedle 3 from falling off or passing through the umbilical cord.

在承接管6相对于承接轮7移动时，承接轮7被带动，进而将连动杆8带动，由于腹部出现剧烈波动，故连动杆8的移动距离较大，在连动杆8移动时，T形杆10在侧面设置的支杆的作用下反向移动，通过其侧面设置的弧形凸起对卡杆11造成挤压，使卡杆11向靠近抽液杆4方向移动，插入到抽液杆4侧面开设的插孔内，将抽液杆4卡死，防止在腹部波动时抽液管1继续抽液，从而达到了避免插针3在脐带移动时抽液，防止靠近脐带内壁对脐带产生较大液压力，进而损伤脐带的效果。When the receivingpipe 6 moves relative to thereceiving wheel 7, thereceiving wheel 7 is driven, and then the connectingrod 8 is driven. Due to the violent fluctuation of the abdomen, the moving distance of the connectingrod 8 is relatively large. When the connectingrod 8 moves , the T-shapedrod 10 moves in the reverse direction under the action of the support rod set on the side, and squeezes the clampingrod 11 through the arc-shaped protrusion set on the side, so that the clampingrod 11 moves toward the direction close to thesuction rod 4, and is inserted into the In the jack opened on the side of thesuction rod 4, thesuction rod 4 is stuck to prevent thesuction pipe 1 from continuing to pump liquid when the abdomen fluctuates, so as to avoid theneedle 3 to draw liquid when the umbilical cord moves, and prevent it from approaching the inner wall of the umbilical cord. The effect of producing a large hydraulic pressure on the umbilical cord, thereby damaging the umbilical cord.

在承接杆5相对于抽液管1移动时，螺杆15与承接杆5发生啮合传动，使得螺杆15转动，又螺杆15与吹气杆17啮合连接，故吹气杆17转动，带动下方的吹气扇转动，吹气扇产生的气流通过风箱16喷出，而风箱16的出口设置在插针3的边缘，故插针3的表面会产生向下的气流。When the receivingrod 5 moves relative to thesuction pipe 1, thescrew 15 and the receivingrod 5 are engaged and driven, so that thescrew 15 rotates, and thescrew 15 is meshed and connected with the blowingrod 17, so the blowingrod 17 rotates to drive the blower below. When the air fan rotates, the airflow generated by the blowing fan is ejected through thebellows 16, and the outlet of thebellows 16 is arranged on the edge of thepin 3, so the surface of thepin 3 will generate downward airflow.

在插针3自动调整深度时，会与孕妇腹腔产生相对位移，而孕妇腹腔的起伏波动是成椭圆状的，因此插针3会与腹腔产生横向挤压力，极有可能在挤压力作用下插针3与腹腔的连接处出现消毒液渗入到腹腔内的现象出现，而沿插针3侧面的气流会将插针3与腹腔连接处的消毒液吹散，从而达到了防止在孕妇腹式呼吸时，消毒液渗入到腹腔内部的效果。When the depth of theneedle 3 is automatically adjusted, it will have a relative displacement with the abdominal cavity of the pregnant woman, and the ups and downs of the pregnant woman's abdominal cavity are elliptical, so theneedle 3 will generate a lateral squeezing force with the abdominal cavity, which is very likely to act on the squeezing force. The phenomenon that the disinfectant seeps into the abdominal cavity occurs at the connection between thelower needle 3 and the abdominal cavity, and the airflow along the side of theneedle 3 will blow the disinfectant at the connection between theneedle 3 and the abdominal cavity, thereby preventing the pregnant woman's abdomen. The effect of the antiseptic solution infiltrating into the abdominal cavity during breathing.
