Description

Technical Field

[0001] The invention belongs to the technical field of medical appliances, and in particular relates to an obstetric fetal head suction and delivery device. Background Art

[0002] In the obstetrics department of a hospital, when a woman is giving birth, she may sometimes encounter fetal hypoxia or difficulty in delivery. In order to ensure the life and health of the fetus and the mother, the fetus needs to be delivered as soon as possible. Otherwise, the delivery will be long, which will endanger the lives of the fetus and the mother. It is necessary to use instruments such as fetal head suction devices to assist in delivery and assist in the delivery of the fetus as soon as possible.

[0003] Existing fetal head suction devices generally work by bringing the suction head into contact with the exposed part of the fetal head and then sucking the head. The doctor pulls the suction head and then pulls out the fetal head. It is currently widely used clinically with obvious effects, but there are also certain problems. It often requires experienced obstetricians to use it. General obstetricians cannot control the suction force when using it. Due to the low suction force, the fetal head may slip during the pulling process, which will interfere with the delivery process, increase the risk factors for the fetus and the mother, and increase the risk of fetal head injury. In addition, the flexibility and functionality are relatively simple. Therefore, in response to the above problems, we propose an obstetric fetal head suction delivery device. Summary of the invention

[0004] In view of the above problems, the object of the present invention is to provide an obstetric fetal head suction device, which can further reduce the slippage of the fetal head and the suction device during use and increase the flexibility and functionality of use.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an obstetric fetal head suction and delivery device, including an obstetric suction cup and a movable ring, one end of the obstetric suction cup is connected to a suction tube, a suction piece is provided in the suction tube, the suction piece is used to form negative pressure suction between the obstetric suction cup and the fetal head, the movable ring is movably connected to the circumferential outer wall of one end of the suction tube close to the obstetric suction cup, two clamping parts are symmetrically hinged on the movable ring, and the two clamping parts are used to clamp the fetal head.

[0006] The beneficial effects of the present invention are as follows: negative pressure is formed inside the obstetric suction cup through the vacuum piece, and the suction cup adsorbs the fetal head, and at the same time, the two clamping parts enter the birth canal to clamp the fetal head. When the fetal head is pulled outward, the clamping parts assist in the delivery of the fetal head, and at the same time can share the dragging force on the obstetric suction cup to avoid the obstetric suction cup and the fetal head from slipping off. In addition, the two hinged clamping parts can be used according to the needs of the doctor, and the obstetric suction cup or the clamping part can be used alone, or both can be used at the same time, thereby improving the flexibility and functionality of use.

[0007] In order to achieve suction fixation between the delivery suction cup and the fetal head; As a further improvement of the above technical solution: the vacuum part includes a piston and a spiral handle, the outer wall of the piston is sealed and slidably connected to the inner wall of the suction tube, the upper end of the piston is rotatably connected to the bottom of the spiral handle, and the end of the spiral handle away from the piston extends to the outside of the suction cylinder and is threadedly connected to the suction cylinder.

[0008] The beneficial effect of this improvement is: by rotating the spiral handle, the spiral handle can enter the suction tube or be rotated out from the inside of the suction tube. Due to the threaded connection between the spiral handle and the suction tube, the spiral handle can be rotated in and out, and at the same time drive the piston to slide inside the suction cylinder. When the spiral handle is rotated outward from the inside of the suction tube, the piston draws the air between the obstetric suction cup and the fetal head into the inside of the suction cylinder, forming a negative pressure environment inside it, thereby adsorbing the fetal head.

[0009] In order to limit the expansion size of the clamping part; As a further improvement of the above technical solution: a limiting sleeve is threadedly connected to the outer wall of the movable ring, and the limiting sleeve is used to limit the expansion size of the two clamping parts.

[0010] The beneficial effect of this improvement is that when the two clamping parts clamp the fetal head, the limiting sleeve contacts the two clamping parts, so that the clamping parts are fixed on the fetal head, which is convenient for assisting the delivery of the fetus.

[0011] In order to prevent the movable ring from moving randomly; As a further improvement of the above technical solution: a rotating sleeve is rotatably connected to the outer wall of the upper end of the movable ring, and the inner wall of the rotating sleeve is threadedly connected to the outer wall of the suction pipe.

[0012] The beneficial effect of this improvement is that the position of the movable ring can be limited by setting the rotating sleeve to prevent the movable ring from moving randomly.

[0013] In order to facilitate the disassembly of the midwifery suction cup and the suction tube; As a further improvement of the above technical solution: the obstetric suction cup is threadedly connected to the suction tube.

[0014] The beneficial effect of this improvement is that by threading the midwifery suction cup and the suction tube, it is easy to disassemble and install the two, and it is easy to disassemble, clean and disinfect after use.

[0015] In order to guide the motion trajectory of the movable ring; As a further improvement of the above technical solution: a slide groove is provided on the outer wall of the suction pipe, and the movable ring is slidably connected to the inside of the slide groove.

[0016] The beneficial effect of this improvement is that the setting of the slide groove can prevent the movable ring from rotating, and when the movable ring slides up and down, the movement trajectory of the movable ring can also be guided. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0020] like Figure 1-5 As shown, an obstetric fetal head suction device comprises a suction cup 1 and a movable ring 4, one end of the suction cup 1 is connected to a suction tube 2, a suction piece 3 is arranged in the suction tube 2, the suction piece 3 is used to form a negative pressure suction between the suction cup 1 and the fetal head, the movable ring 4 is movably connected to the outer wall of the circumference of one end of the suction tube 2 close to the suction cup 1, and two clamping parts 5 are symmetrically hinged on the movable ring 4, and the two clamping parts 5 are used to clamp the head of the fetus; Specifically, the obstetric suction cup 1 can be in various forms such as a hollow hemispherical shape or a hollow truncated cone shape, and the obstetric suction cup 1 can be made of rubber, silicone and other materials. The clamping portion 5 is in the shape of a smooth arc. When it is necessary to assist in the delivery of the fetus, the two clamping portions 5 are extended into the birth canal, and then the fetal head is clamped between the two clamping portions 5. After the clamping is completed, the obstetric suction cup 1 is brought into contact with the fetal head, and a negative pressure suction is formed between the obstetric suction cup 1 and the fetal head through the vacuum member 3, so that the obstetric suction cup 1 is fixed on the fetal head, and then the fetal head is pulled outward. In the process of pulling the fetal head, due to the clamping effect of the clamping portion 5, part of the pulling force of the obstetric suction cup 1 is shared, reducing the risk of the obstetric suction cup 1 slipping off, and the force for pulling out the fetal head is greater, making it easier to assist the delivery of the fetal head. At the same time, the doctor can also choose to use the obstetric suction cup 1 or the clamping portion 5 alone, or use both at the same time, according to needs, thereby improving the flexibility and functionality of use.

[0021] Preferably, the vacuum member 3 includes a piston 301 and a spiral handle 302. The outer wall of the piston 301 is sealingly and slidingly connected to the inner wall of the suction tube 2. The upper end of the piston 301 is rotatably connected to the bottom of the spiral handle 302. The spiral handle 302 extends to the outside of the suction cylinder away from the piston 301 and is threadedly connected to the suction cylinder. By rotating the spiral handle 302, the spiral handle 302 enters the suction tube 2 or is rotated out from the inside of the suction tube 2. Since the spiral handle 302 is threadedly connected to the suction tube 2, the spiral handle 302 can be rotated in and out, and at the same time drive the piston 301 to slide inside the suction cylinder. When the spiral handle 302 is rotated out from the inside of the suction tube 2, the piston 301 draws the air between the midwifery suction cup 1 and the fetal head into the inside of the suction cylinder, so that a negative pressure environment is formed inside the suction cylinder to adsorb the fetal head.

[0022] Preferably, a limiting sleeve 6 is threadedly connected to the outer wall of the movable ring 4, and the limiting sleeve 6 is used to limit the expansion size of the two clamping parts 5. When the two clamping parts 5 clamp the fetal head, the limiting sleeve 6 contacts the two clamping parts 5, so that the clamping parts 5 are fixed on the fetal head, which is convenient for assisting the delivery of the fetus.

[0023] Preferably, a rotating sleeve 7 is rotatably connected to the outer wall of the upper end of the movable ring 4, and the inner wall of the rotating sleeve 7 is threadedly connected to the outer wall of the suction tube 2. By setting the rotating sleeve 7, the position of the movable ring 4 can be limited to prevent the movable ring 4 from moving at will.

[0024] Preferably, the obstetric suction cup 1 and the suction tube 2 are threadedly connected, and the obstetric suction cup 1 and the suction tube 2 are threadedly connected to facilitate disassembly and installation between the two, and are easy to disassemble, clean and disinfect after use.

[0025] Preferably, a slide groove 8 is provided on the outer wall of the suction tube 2, and the movable ring 4 is slidably connected to the inside of the slide groove 8. The setting of the slide groove 8 can prevent the movable ring 4 from rotating, and can also guide the movement trajectory of the movable ring 4 when the movable ring 4 slides up and down.

[0026] The working principle and use process of the present invention are as follows: when using the device, first rotate the rotating sleeve 7 to make the movable ring 4 in a suitable position, then put the two clamping parts 5 into the birth canal, then make the two clamping parts 5 clamp the fetus's head, then contact the midwifery suction cup 1 with the fetal head, and by rotating the spiral handle 302, the spiral handle 302 drives the piston 301 to slide in the suction cylinder, and then the air inside the midwifery suction cup 1 is extracted to form a negative pressure environment inside it, and the midwifery suction cup 1 is adsorbed on the fetal head, and then the limiting sleeve 6 is rotated to make the bottom of the limiting sleeve 6 against the clamping part 5, so that the two clamping parts 5 are tightly attached to the fetal head, and then the suction tube 2 is pulled. At this time, due to the clamping effect of the clamping part 5, a part of the pulling force is shared, reducing the risk of the midwifery suction cup 1 slipping off. At the same time, the doctor can also choose to use the midwifery suction cup 1 or the clamping part 5 alone according to needs, or use both at the same time, thereby improving the flexibility and functionality of use.
