Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical liquid aspiration, and in particular relates to an electric integrated press-type liquid aspiration device. Background Art
[0002] Amniocentesis is a medical test or treatment commonly used for prenatal examinations. It is usually used to detect whether the fetus has genetic diseases or chromosomal or genetic abnormalities, intrauterine infection, or to reduce the amount of amniotic fluid in cases of polyhydramnios to improve the discomfort symptoms of pregnant women caused by polyhydramnios, such as chest tightness and shortness of breath. This procedure is usually performed after the 18th week of pregnancy. By inserting a thin needle into the pregnant woman's abdomen, the amniotic fluid is sucked out by external negative pressure to detect whether the fetus has genetic diseases, intrauterine infection, or to improve the discomfort symptoms of pregnant women caused by polyhydramnios, such as chest tightness and shortness of breath.
[0003] Liquid aspiration devices are devices used to quickly and safely extract liquids from containers. They are widely used in laboratories, healthcare, and industry. They typically operate based on a siphon or mechanical method, resulting in a simple structure and ease of operation. Modern liquid aspiration devices emphasize user-friendly design and intelligent functionality, featuring self-sealing and leak-proof features to enhance safety and convenience. With technological advancements, future liquid aspiration devices will become even more efficient and intelligent, meeting the liquid extraction needs of various industries.
[0004] Electric aspiration technology is widely used in the medical field, particularly for procedures requiring efficient, high-volume, and precise aspiration of fluids, such as amniocentesis during amniocentesis. Excessive amniotic fluid volume requires prolonged, constant-pressure aspiration. Electric aspiration systems offer significant advantages over traditional mechanical methods, including high efficiency, stable operation, and robust controllability. They can precisely adjust suction force and aspiration speed to meet specific needs, ensuring greater precision and safety. However, mechanical aspiration still has limitations in some procedures, particularly regarding patient sensory experience. While mechanical methods provide continuous power output, their operating mode and lack of adjustable force can cause significant discomfort or pain during the procedure. For example, during certain aspiration procedures, particularly when amniotic fluid volumes are low and fetal movements are frequent, precise positioning and constant adjustment of direction and depth are crucial. Mechanical devices, lacking precise control over force, direction, and speed, can lead to excessive suction or unstable operation, increasing patient discomfort and the risk of fetal injury. In contrast, traditional manual aspiration is still widely used in some settings. Therefore, how to combine the two has always been a problem that needs to be solved. Summary of the Invention
[0005] The purpose of the present invention is to provide an electric integrated press-type liquid suction device in order to solve the problem that the traditional liquid suction device mentioned above can only achieve the accuracy of mechanical operation and the incompatibility of manual operation accuracy.
[0006] The technical solution adopted by the present invention is as follows: an electric integrated press-type liquid suction device, including a receiving tube, the inner surface of the upper end of the receiving tube is fixedly connected with an internal thread, the inner surface of the receiving tube is provided with an isolation plate, the outer surface of the receiving tube corresponding to the isolation plate is fixedly connected with an electric suction connecting tube, the inner surface of the receiving tube is movably connected with an external thread, the upper surface of the external thread is fixedly connected with a suction cover, and the upper surface of the receiving tube is fixedly connected with a sealing ring.
[0007] By adopting the above technical solution, the receiving tube and the aspiration cover are screwed together through internal and external threads, and the sealing ring ensures the sealing between the receiving tube and the aspiration cover. After the liquid flows into the aspiration cover, it is blocked by the isolation plate and falls into the outlet pipe under the action of gravity and then collected and stored in the storage barrel. The electric suction connecting tube is convenient for connecting to the medical suction pump for electric liquid aspiration operation. The overall aspiration operation is stable, and the aspiration effect is better guaranteed.
[0008] In a preferred embodiment, a suction pipe is fixedly connected to the inner surface of the suction cover, and an oblique sealing sheet is provided on the lower surface of the suction pipe.
[0009] By adopting the above technical solution, when the suction pipe squeezes the oblique sealing piece to let the liquid flow out, the suction cover is opened to let the liquid flow in.

The infusion rate can be monitored in real time, allowing medical staff to understand the progress of treatment in a timely manner and make necessary adjustments. It simplifies the operating procedures of medical staff, reduces the complexity of manual adjustment, and makes the infusion process more efficient and convenient.
[0014] In a preferred embodiment, a first connecting pipe is fixedly connected to the outer surface of the electric suction connecting pipe, and an emergency storage barrel is fixedly connected to the outer surface of the first connecting pipe.
[0015] By adopting the above technical solution, the first connecting pipe provides a channel for the electric negative pressure. After the emergency storage tank is full of water, it flows in through the first connecting pipe for temporary collection.
[0016] In a preferred embodiment, a medical suction pump is provided on the outer surface of the emergency storage barrel, and a button is provided on the outer surface of the medical suction pump.
[0017] By adopting the above technical solution, the medical suction pump is the main component for providing electric negative pressure. Its operation is completed by pressing a button, providing continuous and uniform output power. The emergency storage barrel is inserted into the output end of the medical suction pump and mechanically adsorbed through the deformation seal at the interface end of the emergency storage barrel 15. The emergency storage barrel 15 is taken out upward for easy flushing and cleaning.

The scale is convenient for penetrating the sucked-out capacity, and the placement feet are convenient for fixing the storage barrel.
[0020] In a preferred embodiment, a handle is movably connected to the outer surface of the storage barrel, and a hanging ring is fixedly connected to the outer surface of the suction cover.
[0021] By adopting the above technical solution, the handle makes it easy to take out the storage barrel and facilitate displacement, and the hanging ring also makes it easy to hang the suction cover externally and fix it.
[0022] In a preferred embodiment, a switch valve is provided on the outer surface of the suction cover, and a second connecting pipe is fixedly connected to the outer surface of the switch valve.
[0023] By adopting the above technical solution, the opening and closing of the switch valve facilitates the connection of the manual suction channel, and the second connecting pipe provides an air flow channel for manual suction.
[0024] In a preferred embodiment, an airbag is fixedly connected to the outer surface of the second connecting tube, and an extrusion plate is provided on the outer surface of the second connecting tube corresponding to the periphery of the airbag.
[0025] By adopting the above technical solution, the squeezing plate is manually pressed to squeeze the airbag, and the airbag gas is discharged. When inhaling, negative pressure is provided to the inside of the second connecting tube to suck out the liquid.
