Description

Technical Field

[0001] The present invention relates to the field of amniotic fluid drainage, and in particular to an obstetric amniotic fluid drainage device. Background Art

[0002] In obstetric clinical practice, amniotic fluid drainage management is a critical and complex task. Amniotic fluid plays a vital role in fetal growth and development, providing a relatively stable fluid environment, buffering external pressure, and protecting the fetus from mechanical damage. However, in certain special circumstances, such as premature rupture of membranes or excessive amniotic fluid requiring decompression, amniotic fluid drainage is necessary to ensure the health and safety of both mother and baby.

[0003] Most existing amniotic fluid drainage devices in clinical practice have several shortcomings. Traditional drainage devices are relatively simple in structure, making it difficult to effectively control the drainage rate and flow rate of amniotic fluid during the drainage process. The flow of amniotic fluid in the vagina is often affected by various factors, such as changes in body position and uterine contractions. This can prevent amniotic fluid from fully and stably entering the drainage tube, resulting in poor drainage effectiveness and an inability to meet actual clinical needs.

[0004] Therefore, it is very necessary to provide an obstetric amniotic fluid drainage device to solve the above technical problems. Summary of the Invention

[0005] Based on the above description, the present invention provides an obstetric amniotic fluid drainage device to solve the problem in the prior art that amniotic fluid cannot fully and stably enter the drainage tube, resulting in poor drainage effect and failure to meet actual clinical needs.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an obstetric amniotic fluid drainage device, comprising an insertion tube body and a drainage part connected to the tube body, the drainage part comprising a drainage tube body connected to the upper end of the insertion tube body, and the drainage tube body is used to drain amniotic fluid; an airbag part is connected to the insertion tube body, and the airbag part comprises an annular inflatable bag connected to the upper end of the insertion tube body, and the annular airbag is used to block the vagina after inflation so that the amniotic fluid can fully enter the drainage tube body.

[0007] Furthermore, a baffle is connected to the insertion tube body, and the drainage tube body is connected to the lower side of the baffle. The baffle is used to seal and separate the upper and lower ends of the insertion tube body to introduce the amniotic fluid on the upper end of the baffle into the drainage tube body.

[0008] Furthermore, the drainage component includes a flow valve, and the flow valve is connected to the lower end of the drainage tube body.

[0009] Furthermore, the insertion tube body is connected to a guide sliding pipe and also includes a puncture member. The puncture member includes a sliding ring body slidably connected to the guide sliding pipe, and the sliding ring body is connected to a puncture needle.

[0010] Furthermore, the sliding ring body is connected to a sliding support rod, and the sliding support rod is connected to a support rod handle.

[0011] Furthermore, the piercing member includes a sliding guide cylinder connected to the baffle, and the sliding support rod is passed through the sliding guide cylinder.

[0012] Furthermore, the airbag component includes an air tube connected to the annular airbag, and the air tube is used to provide an inflation channel for the annular airbag.

[0013] Furthermore, the airbag component includes an air valve, which is connected to the lower end of the trachea and is used to control the on / off of the trachea.

[0014] Furthermore, a tube handle is connected to the insertion tube.

[0015] Furthermore, an auxiliary rod is connected between the insertion tube body and the tube body handle.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] The drainage part is specifically composed of a drainage tube body, one end of which is connected to the upper end of the insertion tube body, and its main function is to drain the amniotic fluid. The airbag part is connected to the insertion tube body, and it includes an annular inflatable bag, which is also connected to the upper end of the insertion tube body. When the annular airbag is inflated, it can block the vagina. In this way, it ensures that the amniotic fluid can fully enter the drainage tube body, thereby achieving effective amniotic fluid drainage. It solves the problem that the amniotic fluid in the existing technology cannot fully and stably enter the drainage tube, resulting in poor drainage effect and inability to meet actual clinical needs.

[0030] like Figures 1 to 5 As shown, an obstetric amniotic fluid drainage device includes an insertion tube body 1 and a drainage member 2 connected to the tube body 1, the drainage member 2 includes a drainage tube body 3 connected to the upper end of the insertion tube body 1, and the drainage tube body 3 is used to drain the amniotic fluid; the insertion tube body 1 is connected to an airbag member 4, and the airbag member 4 includes an annular inflation bag 5 connected to the upper end of the insertion tube body 1, and the annular airbag 5 is used to block the vagina after inflation so that the amniotic fluid can fully enter the drainage tube body 3.

[0031] In this embodiment, the drainage member 2 is specifically composed of a drainage tube body 3, one end of which is connected to the upper end of the insertion tube body 1, and its main function is to drain the amniotic fluid. The airbag member 4 is connected to the insertion tube body 1, and it includes an annular inflatable bag 5, which is also connected to the upper end of the insertion tube body 1. When the annular bag 5 is inflated, it can block the vagina. In this way, it ensures that the amniotic fluid can fully enter the drainage tube body 3, thereby achieving effective amniotic fluid drainage. This solves the problem in the prior art that amniotic fluid cannot fully and stably enter the drainage tube, resulting in poor drainage effect and inability to meet actual clinical needs.

[0032] In some embodiments, a baffle 6 is connected to the insertion tube body 1, and the drainage tube body 3 is connected to the lower side of the baffle 6. The baffle 6 is used to seal and separate the upper and lower ends of the insertion tube body 1 to introduce the amniotic fluid at the upper end of the baffle 6 into the drainage tube body 3.

[0033] In some embodiments, the drainage member 2 includes a flow valve 7 , and the flow valve 7 is connected to the lower end of the drainage tube body 3 .

[0034] In this embodiment, the baffle 6 is used to seal and separate the upper and lower ends of the insertion tube 1, so as to guide the amniotic fluid at the upper end of the baffle 6 into the drainage tube 3. The flow valve 7 is connected to the lower end of the drainage tube 3. In this way, the flow of amniotic fluid into the drainage tube 3 can be effectively and accurately controlled.

[0035] In some embodiments, the insertion tube body 1 is connected to a guide sliding pipe 10 and also includes a puncture member 11. The puncture member 11 includes a sliding ring body 12 slidably connected to the guide sliding pipe 10, and the sliding ring body 12 is connected to a puncture needle 13.

[0036] In some embodiments, a sliding support rod 14 is connected to the sliding ring body 12 , and a support rod handle 15 is connected to the sliding support rod 14 .

[0037] In some embodiments, the piercing member 11 includes a sliding guide cylinder 16 connected to the baffle 6 , and the sliding support rod 14 is inserted into the sliding guide cylinder 16 .

[0038] In this embodiment, the support rod handle 15 is used to push the sliding support rod 14 so that the puncture needle 13 punctures the amniotic fluid, thereby improving the convenience of puncturing the amniotic fluid.

[0039] In some embodiments, the airbag component 4 includes an air tube 8 connected to the annular airbag 5 , and the air tube 8 is used to provide an inflation channel for the annular airbag 5 .

[0040] In some embodiments, the airbag component 4 includes an air valve 9 , which is connected to the lower end of the air pipe 8 . The air valve 9 is used to control the on / off state of the air pipe 8 .

[0041] In this embodiment, the air valve 9 is used to control the on / off of the air pipe 8 . The air pipe 8 is used to provide an inflation channel for the annular air bag 5 . Gas can be filled into the annular air bag 5 through the air pipe 8 .

[0042] In some embodiments, a tube handle 17 is connected to the insertion tube 1 .

[0043] In some embodiments, an auxiliary rod 18 is connected between the insertion tube body 1 and the tube body handle 17 .

[0044] Example 1:

[0045] The medical staff holds the tube body handle 17, and the auxiliary rod 18 can increase the stability of the grip. Insert the insertion tube body 1 until it reaches the appropriate position. Open the air valve 9 and inflate the annular air bag 5 through the trachea 8. As the gas is injected, the annular air bag 5 gradually expands until it effectively blocks the vagina, allowing amniotic fluid to fully enter the drainage tube body 3. After inflation is completed, close the air valve 9 to prevent gas leakage and ensure that the annular air bag 5 remains inflated. Because the baffle 6 seals and separates the upper and lower ends of the insertion tube body 1, amniotic fluid will accumulate at the upper end of the baffle 6. Under the action of gravity and other factors, the amniotic fluid will flow downward through the drainage tube body 3. Medical staff can control the drainage speed of the amniotic fluid by adjusting the flow valve 7 according to actual conditions. For example, if the amniotic fluid flows out too quickly, the flow valve 7 can be appropriately closed; if the outflow speed is too slow, the flow valve 7 can be appropriately opened. When it is necessary to puncture the fetal membrane, the medical staff holds the support rod handle 15 and drives the sliding ring body 12 to slide on the guide sliding pipe 10 by sliding the sliding support rod 14 in the sliding guide cylinder 16. Push the support rod handle 15 to move the puncture needle 13 toward the fetal membrane until the fetal membrane is punctured. During the operation, pay attention to controlling the force and direction to avoid damage to the surrounding tissues. After the fetal membrane is punctured, the amniotic fluid will flow more smoothly into the drainage tube body 3, and the amniotic fluid drainage operation will continue. When the amniotic fluid drainage is completed, open the air valve 9 to release the gas in the annular inflatable bag 5 to restore it to its original state. The medical staff holds the tube body handle 17 to pull it out.
