On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0029] Embodiment 1
[0030] like Figure 1-Figure 4 As shown, a fetal head suction device for delivering a fetus in this embodiment includes a suction cup assembly 1 and an air guide assembly 2.
[0031] Specifically, the suction cup assembly 1 includes a first suction cup 11 and a second suction cup 12 in the shape of a bowl, wherein the first suction cup 11 and the second suction cup 12 are both in the shape of a bowl, and the depth of the first suction cup 11 is deeper than that of the second suction cup 12; the second suction cup 12 is installed inside the first suction cup 11 and the front end of the second suction cup 12 is connected to the inner wall of the first suction cup 11, and the tail end of the second suction cup 12 is spaced from the tail end of the first suction cup 11, which can respectively suction the head of the fetus to different degrees; the first suction cup 11 and the second suction cup 12 are symmetrically divided into four suction areas by the horizontal midline and the vertical midline of the first suction cup 11, and the first suction cup 11 is a sandwich structure composed of an inner wall and an outer wall, so that the first suction cup 11 has sufficient suction space, so that the first suction cup 11 is sucked on the head of the fetus, and the space enclosed by the inner wall of the first suction cup 11 and the side wall of the second suction cup 12 is used to accommodate the head of the fetus, so that the first suction cup 11 can be sucked on the head of the fetus. A suction cup 11 and a second suction cup 12 firmly hold the head of the fetus to prevent it from falling due to insufficient suction of the first suction cup 11 and the second suction cup 12 during the pulling process; a plurality of first through holes 111 are provided on the inner wall of the first suction cup 11, and a plurality of second through holes 121 are provided on the side wall of the second suction cup 12, and the plurality of first through holes 111 and the plurality of second through holes 121 are respectively and evenly located in four suction areas, thereby avoiding the anterior fontanelle and the posterior fontanelle of the fetus, avoiding sucking the anterior fontanelle and the posterior fontanelle of the fetus to too high a height, and thus avoiding permanent damage to the fetal skull; the air guide component 2 is connected to the tail end of the first suction cup 11, and the air guide component 2 can be evacuated through the air suction component 7, so that the first suction cup 11 and the second suction cup 12 can suck the head of the fetus, so that the air guide component 2 can increase the attraction of the first suction cup 11 to the fetal skull, and reduce the attraction of the anterior fontanelle and the posterior fontanelle at the fetal skull. This embodiment provides a first suction cup 11 and a second suction cup 12, and opens a plurality of first through holes 111 and second through holes 121 in four suction areas and on the first suction cup 11 and the second suction cup 12, which can strongly suck the surrounding of the anterior fontanelle and the posterior fontanelle of the fetus, respectively, and lightly suck the anterior fontanelle and the posterior fontanelle of the fetus, thereby avoiding damage to the fetal skull. Moreover, when the first suction cup 11 and the second suction cup 12 suck the fetal head, it is no longer necessary to use a marker to mark the anterior fontanelle and the posterior fontanelle of the fetus, making the operation simpler, saving operation time, reducing the pain of the mother during childbirth, and reducing the production time. Preferably, the first suction cup 11 and the second suction cup 12 are both made of a gel material, which has a good deformation ability and a better suction ability, so that the first suction cup 11 and the second suction cup 12 can be firmly sucked on the fetal head.
[0032] Furthermore, if Figure 2As shown, the first suction cup 11 includes a first shell 112 and a second shell 113; the second shell 113 is located inside the first shell 112 and the first shell 112 and the second shell 113 are made as one piece, and the two respectively constitute the inner wall and outer wall of the first suction cup 11; the front end of the first shell 112 is connected to the second shell 113 by bending, which is more convenient during production, and the manufacturing process is simple and convenient, thereby improving the manufacturing work efficiency; a plurality of first through holes 111 are located on the second shell 113; a first air guide channel 3 is provided between the first shell 112 and the second shell 113, and the first air guide channel 3 is connected to the air guide component 2, and the air guide component 2 can be evacuated through the plurality of first through holes 111, and the air is evacuated along the first air guide channel 3, so that the first suction cup 11 can be firmly sucked on the head of the fetus. Preferably, a second air guide channel 4 is formed between the inner wall of the first suction cup 11 and the side wall of the second suction cup 12, and the second air guide channel 4 is connected to the air guide component 2, so that when the vacuum component 7 is vacuuming, air enters the second air guide channel 4 from the multiple second through holes 121, and is sucked away by the vacuum component 7 through the air guide component 2, so that the second suction cup 12 is sucked around the anterior fontanelle and posterior fontanelle of the fetal skull, thereby avoiding the anterior fontanelle and posterior fontanelle of the baby's skull and avoiding damage to the fetal skull.
[0033] Furthermore, the multiple first through holes 111 are located in front of the multiple second through holes 121. The multiple first through holes 111 can suck air at a position away from the anterior fontanelle and the posterior fontanelle, so that the first suction cup 11 is firmly sucked on the fetus's head to prevent the first suction cup 11 from falling. The multiple second through holes 121 can enable the second suction cup 12 to attract the surrounding areas of the anterior fontanelle and the posterior fontanelle of the fetal skull, so that the suction cup assembly 1 is firmly sucked on the fetus's head through the mutual cooperation of the first suction cup 11 and the second suction cup 12.
[0034] Furthermore, the diameter of the first through hole 111 is greater than the diameter of the second through hole 121. When the first suction cup 11 sucks the fetus's head, it can increase the suction force so that the first suction cup 11 is firmly sucked on the fetus's head. The second suction cup 12 passes through the second through hole 121. When the second suction cup 12 sucks air on the fetus's head, due to the small diameter of the second through hole 121, the pressure during suction can be reduced, so that when the second suction cup 12 sucks the anterior fontanelle and posterior fontanelle of the fetus, the suction force of the second suction cup 12 can be smaller, so that when the second suction cup 12 sucks the anterior fontanelle and posterior fontanelle, the height of the scalp sucked up by the second suction cup 12 is reduced, thereby reducing damage to the anterior fontanelle and posterior fontanelle of the head.
[0035] Furthermore, if Figure 2 As shown, the air guide assembly 2 includes a first air guide pipe 21 and a second air guide pipe 22 .
[0036] Specifically, one end of the first air duct 21 is connected to the rear end of the first shell 112, and the other end is connected to the fixing ring 5. The second air duct 22 is sleeved in the first air duct 21, one end of the second air duct 22 is connected to the second shell 113 and communicates with the second air duct 4, and the other end is communicated with the fixing ring 5 (it should be noted here that the first air duct 21 and the second air duct 22 can be made integrally with the first suction cup 11. When the first suction cup 11 is manufactured and shipped from the factory, the middle position of the first suction cup 11 is spherical, and the first air duct 21 and the second air duct 22 are respectively located on both sides of the spherical shape, and the axis of the first air duct 21 is consistent with the axis of the second air duct 22. When in use, the second air duct 22 only needs to be moved along the The axis of the first airway tube 21 is inserted into the first airway tube 21, and the spherical shape connected to the second airway tube 22 is bent as the second airway tube 22 is inserted, so that the first suction cup 11 forms a sandwich structure, the second shell 113 is connected to the second airway tube 22, and the first shell 112 is connected to the first airway tube 21); the gap channel between the first airway tube 21 and the second airway tube 22 is connected to the first airway channel 3, which can guide the first suction cup 11 and the second suction cup 12 through the first airway channel 3 and the second airway channel 4 respectively, thereby realizing the division of labor of the first suction cup 11 and the second suction cup 12, and then making the first suction cup 11 and the second suction cup 12 sucked on the head of the fetus at the same time. The first airway tube 21 is screwed with the fixing ring 5, which can realize convenient installation and disassembly. Since the suction cup assembly 1 is a disposable medical device, the suction cup assembly 1 can be quickly replaced by screwing, thereby improving work efficiency.
[0037] Furthermore, if Figure 1 As shown, the fetal head suction device also includes a water collecting component 6; a nano-permeable membrane 8 is installed inside the fixing ring 5, which can block the amniotic fluid and other liquids adhering to the fetal head, preventing the amniotic fluid and other liquids from entering the suction component 7, thereby avoiding damage to the device; the water collecting component 6 is installed on the outer wall of the fixing ring 5 to guide and collect the amniotic fluid of the fetal head, thereby improving the hygiene of the operating room.
[0038] Specifically, the water collecting component 6 includes a water pipe 61 and a water collecting bin 62; one end of the water pipe 61 is installed on the outer wall of the fixing ring 5, and the other end is connected to the water collecting bin 62. The end of the water pipe 61 connected to the fixing ring 5 is located at the front end of the nano-permeable membrane 8. When liquids such as amniotic fluid flow through the fixing ring 5, since the nano-permeable membrane 8 is located at the tail end where the water pipe 61 is connected to the fixing ring 5, liquids such as amniotic fluid enter the water collecting bin 62 through the water pipe 61, thereby realizing the diversion and collection of liquids such as amniotic fluid, thereby improving the hygiene of the operating room.
[0039] Through the above structure, the working principle of a fetal head suction device for delivering a fetus in this embodiment is:
[0040] like Figure 1 As shown, first assemble the device and move it to the operating room where delivery is about to take place. When fetal head suction is required, disinfect the suction cup assembly 1 and buckle the front end of the first suction cup 11 on the head of the fetus. The four suction areas correspond to the surroundings of the anterior fontanelle or posterior fontanelle of the fetus, respectively, to avoid strong suction on the anterior fontanelle or posterior fontanelle. The suction assembly 7 is driven to perform suction, and the air between the fetal head and the first suction cup 11 enters the suction assembly 7 from the first air guide tube 21 along the first air guide channel 3 through the first through hole 111. At the same time, the second suction cup 12 draws the air from the second air guide tube 22 along the second air guide channel 4 into the suction assembly 7 through the second through hole 121, so that the first suction cup 11 and the second suction cup 12 firmly suck the fetal head, and due to the effect of the four suction areas and the diameter of the second through hole 121 being smaller than the diameter of the first through hole 111, the area around the anterior fontanelle or the posterior fontanelle of the fetus can be strongly sucked during suction, while the area at the anterior fontanelle or the posterior fontanelle only needs to be slightly sucked, that is, the scalp at the anterior fontanelle or the posterior fontanelle does not need to be sucked up too high, thereby avoiding causing greater damage to the fetal skull. When the first suction cup 11 and the second suction cup 12 suck the fetal head, the doctor puts the fetus in the correct position by hand and takes the fetus out of the mother's belly by pulling. When the first suction cup 11 and the second suction cup 12 suck the fetal head, since the fetal head will adhere to liquids such as amniotic fluid, the liquid will be released from the first air guide tube 21 and the second air guide tube 22 into the fixing ring 5 through the first through hole 111 and the second through hole 121 along the first air guide channel 3 and the second air guide channel 4. Since the nano-permeable membrane 8 is installed in the fixing ring 5, the liquid cannot seep out from the nano-permeable membrane 8. Therefore, the liquid can only enter the water collection tank 62 through the water guide tube 61, thereby collecting liquids such as amniotic fluid, so as to improve the hygiene of the device and the operating room, and also reduce the damage rate of the device.
