Abstract
Description
Technical Field
[0001] This utility model relates to the field of amniotic fluid decompression technology, and in particular to a decompression device for treating excessive amniotic fluid during prenatal diagnosis. Background Technology
[0002] Prenatal diagnosis refers to various tests and diagnoses performed during pregnancy to assess the health of the mother and fetus and predict potential risks. These diagnoses help doctors detect potential problems early and take appropriate measures to protect the safety of both mother and baby. Prenatal diagnosis includes techniques such as ultrasound examination, blood tests, amniocentesis, and chorionic villus sampling, which can detect chromosomal abnormalities, congenital malformations, and genetic diseases in the fetus. When polyhydramnios is diagnosed, a decompression device is used to aspirate the amniotic fluid to prevent excessive pressure in the mother's body. However, existing decompression devices have at least the following drawbacks: Most existing decompression devices require medical personnel to insert a suction syringe into the mother's body for aspiration and decompression. During the aspiration process, the lack of auxiliary positioning can easily lead to the syringe shifting and increasing the mother's pain. Therefore, we have introduced a decompression device for polyhydramnios in prenatal diagnosis. Utility Model Content
[0003] The main objective of this invention is to provide a decompression device for polyhydramnios during prenatal diagnosis, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A decompression device for polyhydramnios during prenatal diagnosis includes a connecting seat, a support frame fixedly connected to the upper end of the connecting seat, the support frame having an arc-shaped structure, an arc-shaped groove inside the support frame, a positioning device slidably connected inside the arc-shaped groove, and an aspiration syringe movably connected inside the positioning device.
[0006] Preferably, the positioning device includes a first sliding frame, which is a semi-circular structure. A limiting sleeve is movably connected to the right end of the first sliding frame. A second sliding frame is movably connected to the right side of the outer surface of the limiting sleeve. Both the first and second sliding frames have through sliding grooves. A circular seat is fixedly connected to the right side of the outer surface of the second sliding frame. A limiting bolt is threaded to the right end of the circular seat. The second sliding frame is a semi-circular structure.
[0007] Preferably, the limiting bolt passes through the circular seat and extends into the sliding groove on the second sliding frame.
[0008] Preferably, the left and right sides of the outer surface of the limiting sleeve are fixedly connected to a connecting shaft, and the upper end of the limiting sleeve has a limiting hole that passes through from top to bottom.
[0009] Preferably, both the first sliding frame and the second sliding frame have round holes at their ends that are close to each other.
[0010] Preferably, the two connecting shafts are respectively movably connected to the circular holes on the first sliding frame and the second sliding frame.
[0011] Preferably, both the first sliding frame and the second sliding frame are movably connected to the support frame, the limiting bolt contacts the right end of the support frame, and both sliding grooves are adapted to the shape of the support frame.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By setting up a support frame, the positioning device and the support frame are slidably connected, allowing the positioning device to be adjusted on the support frame. Since the support frame has an arc-shaped structure, the positioning device can be adjusted in an arc shape to adapt to the abdomen of the mother. Then, the aspiration syringe is inserted into the positioning device for puncture and aspiration, which improves the stability of the aspiration syringe during aspiration and avoids the aspiration syringe shaking and becoming unstable.
[0014] 2. By setting a positioning device, the first and second sliding frames are slidably connected to the support frame. By rotating the limiting bolt to compress the support frame, the position of the positioning device after adjustment can be limited, which improves the stability of the positioning device. Since the limiting sleeve is movably connected to the first and second sliding frames through two connecting shafts, the angle of the limiting sleeve can be adjusted, thereby adjusting the insertion angle of the suction syringe and improving the flexibility of use.

[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A decompression device for polyhydramnios during prenatal diagnosis includes a connecting seat 1, a support frame 2 fixedly connected to the upper end of the connecting seat 1, the support frame 2 having an arc-shaped structure, an arc-shaped groove 3 opened inside the support frame 2, a positioning device 4 slidably connected inside the arc-shaped groove 3, and an aspiration syringe 5 inserted and movably connected inside the positioning device 4.
[0025] In this embodiment, the positioning device 4 includes a first sliding frame 41, which has a semi-circular structure. A limiting sleeve 46 is movably connected to the right end of the first sliding frame 41. A second sliding frame 42 is movably connected to the right side of the outer surface of the limiting sleeve 46. Both the first sliding frame 41 and the second sliding frame 42 have through sliding grooves 45. A circular seat 43 is fixedly connected to the right side of the outer surface of the second sliding frame 42. A limiting bolt 44 is threaded to the right end of the circular seat 43. The second sliding frame 42 has a semi-circular structure. The limiting bolt 44 passes through the circular seat 43 and extends to the second sliding frame 42. Inside the sliding groove 45 on the support frame 2; the left and right sides of the outer surface of the limiting sleeve 46 are fixedly connected to the connecting shaft 462, and the upper end of the limiting sleeve 46 has a limiting hole 461 that passes through from top to bottom; the first sliding frame 41 and the second sliding frame 42 have round holes 411 at their close ends; the two connecting shafts 462 are respectively inserted and movably connected to the round holes 411 on the first sliding frame 41 and the second sliding frame 42; the first sliding frame 41 and the second sliding frame 42 are both inserted and movably connected to the support frame 2, the limiting bolt 44 contacts the right end of the support frame 2, and the two sliding grooves 45 are adapted to the shape of the support frame 2.
[0026] It should be noted that this utility model is a decompression device for polyhydramnios during prenatal diagnosis. During use, the connecting seat 1 is fixed to the bed to ensure stability and prevent wobbling, positioning the support frame 2 at the mother's abdomen. This effectively supports and stabilizes subsequent operating components. Because the positioning device 4 and the support frame 2 are slidably connected, medical staff can easily adjust the position of the positioning device 4 on the support frame 2 as needed, making it more conform to the mother's abdominal curve. Once the positioning device 4 is adjusted to the appropriate position, rotating the limiting bolt 44 moderately compresses the support frame 2, firmly locking the position of the positioning device 4 and greatly improving its stability. This design ensures that the positioning device 4 maintains a stable posture during suction, avoiding unnecessary movement. Since the limiting sleeve 46 is movably connected to the first sliding frame 41 and the second sliding frame 42 via two connecting shafts 462, medical staff can flexibly adjust the angle of the limiting sleeve 46 as needed. This design allows the insertion angle of the aspiration syringe 5 to be adjusted according to the actual situation of the parturient, further improving its flexibility and adaptability. When the aspiration syringe 5 is inserted into the positioning device 4 for puncture and aspiration, the stability of the positioning device 4 is greatly improved, allowing the aspiration syringe 5 to maintain a stable posture during aspiration, avoiding shaking and instability. This not only improves the efficiency and accuracy of aspiration but also reduces potential risks to the parturient.
