Description

Technical Field

[0001] The present invention belongs to the field of obstetrics and gynecology medical equipment, and specifically relates to an obstetric suction delivery device. Background Art

[0002] When obstetricians and gynecologists perform natural childbirth for parturients, they need doctors to assist in the delivery of the fetus. When the fetus's head is exposed, in order to prevent the fetus from suffocation, the doctor usually holds the fetus's head with both hands and cooperates with the parturient to pull the fetus out of the uterus to achieve the goal of mother and child safety. Usually, there are also midwifery instruments to help parturients deliver, using midwives to apply traction to the fetus from the outside to assist the fetus to pass through the birth canal;

[0003] However, in the fetal head suction-type delivery forceps with application number CN201220939920.0, a suction cup is set in the middle of the clamp, and the suction cup is pressed against the fetal head to pull the fetus outward for delivery. However, when the fetal position is that the buttocks leak out first, the fetal surface is uneven, which reduces the fit between the suction cup and the fetus and weakens the fixing effect of the suction cup. At the same time, in the breech delivery, the fetal neck leaks out before the head, and the diameter of the neck is smaller than the head, so that the birth canal that has just been expanded by the shoulders shrinks inward when it moves to the neck. The neck is short, and the head needs to expand outward suddenly during delivery. If the mother is not strong enough at this time, it is easy to have a dystocia. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] Please refer to Figures 1 to 9 , an obstetric suction delivery device, comprising a support frame 1, an adjustment component 6 and a restraint component 9;

[0039] A guide rod 2 is fixed to the inner side of the support frame 1, a first support rod 4 is slidably arranged on the outer side of the guide rod 2, a driving assembly 5 is arranged on the inner side of the first support rod 4, and an adjustment assembly 6 is slidably arranged on one end of the first support rod 4 away from the support frame 1;

[0040] The adjustment component 6 includes a first rack 61, a second rack 62 and a fixed block 63, and the first rack 61 is meshed on the outer side of the driving component 5, and the second rack 62 is meshed on the side of the driving component 5 away from the first rack 61. The outer sides of the first rack 61 and the second rack 62 are both fixed with a fixed block 63 that penetrates the first support rod 4, and the two fixed blocks 63 are respectively located on both sides of the first support rod 4. The end of the adjustment component 6 away from the support frame 1 is fixed with a restraint component 9;

[0041] The restraint assembly 9 includes an air cushion 91, a first air bag 92, a second air bag 93 and a negative pressure structure 94, and the fixed block 63 on the first rack 61 is fixedly connected to one end of the first air bag 92, the fixed block 63 on the second rack 62 is fixedly connected to one end of the second air bag 93, and the air cushion 91 is fixed between the first air bag 92 and the second air bag 93, and the negative pressure structure 94 is fixed to one end of the first air bag 92 away from the second air bag 93, and the second support rod 7 is fixed to the other end of the first air bag 92 and the second air bag 93.

[0042] When the fetus is in an abnormal position, as long as the fetal weight is within 2500-3000 grams and the mother's pelvic measurement is normal, breech delivery can be performed.

[0043] When in use, the first support rod 4, the second support rod 7 and the restraint assembly 9 are inserted into the body of the parturient through the birth canal. At this time, the restraint assembly 9 is in a compressed state to reduce the volume of the restraint assembly 9, thereby facilitating the insertion of the restraint assembly 9. At the same time, the material of the restraint assembly 9 is latex material, which can provide a comfortable touch compared to traditional hard forceps and reduce damage to the parturient. Then the medical staff moves the second support rod 7 along the guide rod 2 to the front end of the fetus's belly, and then adjusts the first support rod 4 along the guide rod 2 until the first support rod 4 surrounds the fetus's lower limbs and merges with the second support rod 7. At this time, the air cushion 91 surrounds the outside of the fetus. At the same time, because the restraint assembly 9 made of latex has good elasticity, the air cushion 91 is surrounded by the outside of the fetus. When restraining the fetus' legs, it can automatically adjust according to the shape and pressure of the skin, thereby reducing the pressure and discomfort caused to the fetus. At the same time, because the guide rod 2 is in the shape of a turbine, the side close to the shaft hole is gathered inward, so that the inner diameter of the air cushion 91 is gradually reduced during the sliding process of the first support rod 4 from the outside to the inside. If the fetus' legs are forked, the restraint of the air cushion 91 can make the legs of the fetus gather inward and reduce the volume occupied by the limbs to facilitate delivery. Then, the first support rod 4 and the second support rod 7 are respectively fixed to the rotating seat 3 on the support frame 1. At this time, the parturient can guide the force to move the restrained fetus toward the birth canal. If the parturient is not strong enough, the support frame 1 and the two support rods can be dragged outward to guide the fetus to move;

[0044] When the fetus's feet are about to be delivered, since the size of the fetus is larger than the distance between the first support rod 4 and the axis of the guide rod 2, the first support rod 4 and the second support rod 7 are inserted into the mother's body at an angle, and the end of the support rod away from the support frame 1 is inclined toward the side away from the axis of the guide rod 2. At this time, the support rods can be slightly adjusted to make the two support rods slightly expand outward, and the medical staff rotates the driving components 5 on the two support rods, and drives the first rack 61 to slide along the first support rod 4 to the side away from the support frame 1 through the driving component 5, and at the same time drives the second rack 62 to the side close to the support frame 1. One end slides, so that the first airbag 92 moves along the first support rod 4 and the second support rod 7 toward the fetus' head, and the fetus is slowly delivered outward until the negative pressure structure 94 on the first airbag 92 contacts the fetus' chin. In this process, there is no need to deliberately go deeper inward, thereby reducing the friction between the birth canal and the support rod, thereby reducing the risk of birth canal damage. At this time, the second airbag 93 is located below the umbilicus of the fetus. At this time, the negative pressure structure 94 is adjusted to inject air into the air cushion 91, so that the air cushion 91 expands outward to form a support, and at the same time forms a negative pressure adsorption at the fetus' chin, using the air cushion 93 to absorb the negative pressure. The support formed by the outward expansion of the air cushion 91 increases the hardness of the air cushion 91 and improves its support. At the same time, the negative pressure structure 94 provides a support point for the second air bag 93, which is conducive to further improving the stability of the restraint component 9 at the fetal neck, so that the birth canal forms a gradual expansion at the fetal neck during delivery, thereby reducing the burden on the parturient and providing protection for the umbilical cord. When the parturient is giving birth, the birth canal is gradually expanded outward by the trumpet-shaped air cushion 91. At this time, the umbilical cord is wrapped inside the air cushion 91, so that when the parturient is insufficient in strength and the birth canal shrinks inward, the air cushion 91 The support of the umbilical cord can reduce the direct flattening of the umbilical cord and the suffocation of the fetus. When the buttocks of the fetus are delivered first, in order to reduce the suffocation of the fetus, the head of the fetus must be delivered within 7 to 8 minutes after the umbilical cord of the fetus is delivered. Otherwise, it is easy to cause dystocia caused by fetal suffocation. By forming a trumpet-shaped air cushion 91 between the head of the fetus and the umbilical cord, the delivery time of the head of the fetus can be increased when the buttocks are delivered first, so as to reduce the dystocia. At the same time, during the movement of the head of the fetus, the birth canal can slowly expand outwards, thereby reducing the pain of delivery for the mother.

[0045] Please refer to Figures 1 to 3 , a limiting ring 41 is fixed to the middle of the first support rod 4 and the second support rod 7, and the first support rod 4 is rotatably connected to the guide rod 2 through the limiting ring 41;

[0046] When the medical staff adjusts the position of the first support rod 4 and the second support rod 7, since the first support rod 4 and the second support rod 7 are rotatably connected to the guide rod 2 through the limiting ring 41, when the position of the ends of the two support rods is adjusted, the first support rod 4 and the second support rod 7 can be rotated with the limiting ring 41 as the center by adjusting the end of the first support rod 4 and the second support rod 7 close to the support frame 1, and the guide rod 2 is used to provide support for the first support rod 4 and the second support rod 7, and the two support rods are slowly expanded outward at the limiting ring 41 to form a trumpet shape, so that the distance between the first support rod 4 and the second support rod 7 on the side close to the birth canal is smaller, thereby reducing damage to the opening of the birth canal.

[0047] Please refer to Figure 5 The first support rod 4 and the second support rod 7 are wrapped with sterile cotton 42, and the outer side of the sterile cotton 42 is wrapped with a latex sleeve 421, and the outer side of the latex sleeve 421 is coated with lubricating oil;

[0048] When in use, the hardness of the outer wall of the first support rod 4 and the second support rod 7 is weakened by the sterile cotton 42, so that when the first support rod 4 and the second support rod 7 are in contact with human skin, the skin at the contact point between the first support rod 4 and the second support rod 7 and the human body can be made softer and more comfortable, reducing the coldness and discomfort caused by direct contact of metal or hard materials with the skin;

[0049] Please refer to Figure 5 to Figure 6 The driving component 5 includes an adjusting wheel 51, a transmission belt 52, and a gear 53. The gear 53 is meshed between the first rack 61 and the second rack 62, and the end of the gear 53 away from the restraining component 9 is rotatably connected to the adjusting wheel 51, and a transmission belt 52 is arranged between the adjusting wheel 51 and the gear 53.

[0050] When in use, the adjusting wheel 51 is located on the outside of the birth canal. When adjusting the position of the first airbag 92 and the second airbag 93, the adjusting wheel 51 is rotated to drive the transmission belt 52 to rotate, and the friction between the transmission belt 52 and the gear 53 is used to drive the gear 53 to rotate. At this time, when the gear 53 rotates, it drives the first rack 61 and the second rack 62 engaged with the gear 53 to slide in both directions at the same time, so that the position of the first airbag 92 and the second airbag 93 can be adjusted on the outside of the birth canal, so that when the position of the restraint assembly 9 changes, the friction of the first support rod 4 and the second support rod 7 on the birth canal is reduced, which is beneficial to reduce damage to the parturient.

[0051] The side walls of the first support rod 4 and the second support rod 7 are penetrated with a slide groove 43, and the sliding path of the fixing block 63 is the same as the path of the slide groove 43;

[0052] By setting the slide groove 43 to limit the moving path of the fixed block 63, it is beneficial to improve the stability of the movement of the fixed block 63. At the same time, the fixed blocks 63 outside the first rack 61 and the second rack 62 are respectively located on both sides of the first support rod 4, so that when the restraint assembly 9 is in a flexible state, the first airbag 92 and the second airbag 93 are not in the same plane, so that the air cushion 91 fixed to the fixed block 63 and the first support rod 4 are not parallel to each other, so that when the first airbag 92 and the second airbag 93 slide toward each other, the additional resistance caused by collision and friction between the two is reduced, which is beneficial to the smoother movement of the fixed block 63, reducing energy loss and improving the smoothness of adjustment of the restraint assembly 9.

[0053] Please refer to Figure 1 , Figure 2 and Figure 7 The inner side of the air cushion 91 is provided with a plurality of air grooves 911, and one end of the plurality of air grooves 911 away from the first air bag 92 forms a communication structure with the second air bag 93. The plurality of transverse air grooves 911 can improve the transverse support of the air cushion 91. Compared with a whole rectangular air cushion 91, when the whole rectangular air cushion 91 is inflated, the air cushion 91 will expand laterally, resulting in a reduction in the restraint effect of the air cushion 91 after expansion. There is flexible latex between the plurality of air grooves 911, so that the edges of the air grooves 911 can be bent and deformed after inflation, so as to improve the restraint of the restraint component 9 after expansion.

[0054] Please refer to Figure 1 , Figure 4 and, Figure 7 The negative pressure structure 94 includes a sterile sponge 941, a sealing tube 942, a piston tube 943, a first hose 944 and a second hose 945. A plurality of sterile sponges 941 are fixed to the end of the first airbag 92 away from the air cushion 91. A sealing tube 942 is fixed at the axis of the guide rod 2, and the inner side of the sealing tube 942 is sealingly and slidably matched with the piston tube 943. A first hose 944 is penetrated through the bottom of the piston tube 943, and the end of the first hose 944 away from the sealing tube 942 is connected to the first airbag 92. A second hose 945 is fixed to the end of the sealing tube 942 away from the guide rod 2, and the end of the second hose 945 away from the sealing tube 942 is connected to the second airbag 93, and the ends of the first hose 944 and the second hose 945 connected to the sealing tube 942 are respectively located on both sides of the piston tube 943.

[0055] When in use, the sealing tube 942 and the first airbag 92 are connected through the first hose 944, and the sealing tube 942 and the second airbag 93 are connected through the second hose 945. If the air in the air cushion 91 is extracted to compress the air cushion 91, the piston tube 943 is pushed inward along the sealing tube 942, so that the volume of the piston tube 943 in the sealing tube 942 close to the rotating seat 3 increases, so that the air in the air groove 911 enters the sealing tube 942 through the second airbag 93, and the excess air in the sealing tube 942 flows out through the first hose 944 and the first airbag 92. At the same time, when it is necessary to expand the restraining assembly 9 outward, the sealing tube 942 is pulled out to activate the restraining assembly 9. The plug tube 943 slides toward the end close to the rotating seat 3, so that the air on the side of the piston tube 943 in the sealing tube 942 close to the rotating seat 3 enters the second air bag 93 through the second hose 945, and enters the air groove 911 through the second air bag 93, so that the air groove 911 expands outward, increasing the support of the air cushion 91. At the same time, the side of the sterile sponge 941 away from the air cushion 91 fits with the skin of the fetus, so that when the sealing tube 942 is pulled outward, the space on the side of the piston tube 943 away from the rotating seat 3 increases, so that the air in the first hose 944 and the first air bag 92 moves into the sealing tube 942, so that a negative pressure effect is formed at the sterile sponge 941, thereby fixing the restraint assembly 9. Since the materials of the sterile sponge 941 and the first air bag 92 are both flexible materials, the negative pressure structure 94 can be easily matched to the contour of the fetal head, thereby increasing the fit between the sterile sponge 941 and the fetus, which is beneficial to improving the fixation effect between the negative pressure structure 94 and the fetus. At the same time, the air cushion 91 is inflated through a sealing tube 942 at the same time, which can form a negative pressure state in the sterile sponge 941 area, which is convenient for medical staff to operate with one hand, thereby facilitating use.

[0056] Please refer to Figure 3 to Figure 4 One end of the piston tube 943 away from the support frame 1 is rotatably connected to the rotating seat 3, and a rotating ring 31 is rotatably connected between the rotating seat 3 and the piston tube 943, and the inner sides of the rotating seat 3 and the rotating ring 31 are penetrated by limiting holes 32.

[0057] Connecting rods 8 are slidably disposed inside the two limiting holes 32 , and ends of the two connecting rods 8 away from the rotating seat 3 are rotatably connected to the first supporting rod 4 and the second supporting rod 7 , respectively.

[0058] An adjusting screw 33 penetrating the rotating seat 3 is arranged on the inner side of the rotating seat 3 , and a bidirectional thread 331 is provided on the outer side of the adjusting screw 33 , and a nut seat 34 is rotatably connected to the outer side of the adjusting screw 33 .

[0059] When in use, when adjusting the position of the first support rod 4 and the second support rod 7, the first support rod 4 and the second support rod 7 are rotated along the guide rod 2. At this time, the ends of the first support rod 4 and the second support rod 7 away from the restraining assembly 9 are respectively connected to the two connecting rods 8 for rotation, thereby driving the connecting rod 8 to rotate with the rotating seat 3 as the center of the circle, thereby providing a fulcrum for the first support rod 4 and the second support rod 7. When the doctor's hands are shaking or physically exhausted, the doctor can support the connection between the support rod and the connecting rod 8 to take a rest, so as to relieve the doctor's fatigue during the delivery process. At the same time, when the doctor adjusts the angle of the end of the first support rod 4 and the second support rod 7, the doctor can drive the connecting rod 8 to slide along the limiting hole 32, thereby changing the distance between the end of the first support rod 4 and the second support rod 7 and the axis of the support frame 1, thereby facilitating angle adjustment. At the same time, the sliding length of the connecting rod 8 is used to facilitate fine-tuning the angle of the two support rods. At the same time, the rotating seat 3 and the rotating ring 31 can rotate relatively. The two connecting rods 8 correspond to the rotating seat 3 and the rotating ring 31 respectively, thereby reducing the mutual interference between the two support rods when adjusting. At the same time, when the positions of the first support rod 4 and the second support rod 7 are adjusted, the adjusting screw 33 is rotated, and the two-way thread 331 on the adjusting screw 33 is used to drive the two nut seats 34 to move toward each other along the adjusting screw 33, until the two nut seats 34 are respectively fitted with the two connecting rods 8, and the static friction between the nut seats 34 and the corresponding connecting rods 8 is increased, thereby fixing the connecting rod 8. At the same time, since the connection between the rotating seat 3 and the rotating ring 31 is located between the two connecting rods 8, when the distance between the two nut seats 34 is reduced, the two connecting rods 8 have a tendency to move toward each other, thereby increasing the static friction at the connection between the rotating ring 31 and the rotating seat 3, which is beneficial to limit the relative rotation between the rotating ring 31 and the rotating seat 3, thereby further limiting the first support rod 4 and the second support rod 7.

[0060] The following is a further description of an obstetric suction delivery device provided by the present invention in conjunction with the accompanying drawings and implementation modes.

[0061] When in use, the first support rod 4, the second support rod 7 and the restraint assembly 9 are put into the body of the parturient through the birth canal, and the piston tube 943 is pushed inward along the sealing tube 942, so that the volume of the piston tube 943 in the sealing tube 942 close to the rotating seat 3 increases, so that the air in the air groove 911 enters the sealing tube 942 through the second air bag 93, so that the restraint assembly 9 is in a compressed state;

[0062] Then, the connecting rod 8, the first supporting rod 4 and the second supporting rod 7 are rotated along the guide rod 2 with the rotating seat 3 as the center, until the first supporting rod 4 surrounds the lower limbs of the fetus and merges with the second supporting rod 7, and then the adjusting screw 33 is rotated, and the two-way thread 331 on the adjusting screw 33 is used to drive the two nut seats 34 to move toward each other along the adjusting screw 33, until the two nut seats 34 are respectively fitted with the two connecting rods 8, and the connecting rod 8, the rotating seat 3 and the rotating ring 31 are fixed;

[0063] When the fetus' feet are about to be delivered, the medical staff rotates the driving components 5 on the two support rods, and drives the first rack 61 to slide along the first support rod 4 to the side away from the support frame 1 through the driving component 5, and drives the second rack 62 to slide toward the end close to the support frame 1, so that the first airbag 92 moves along the first support rod 4 and the second support rod 7 toward the fetus' head, and the fetus is slowly delivered outward until the negative pressure structure 94 on the first airbag 92 contacts the fetus's chin. At this time, the sealing tube 942 is pulled out, and the piston tube 943 moves toward the rotating end. One end of the movable seat 3 slides, so that the air in the piston tube 943 in the sealing tube 942 near the rotating seat 3 side enters the second air bag 93 through the second hose 945, and enters the air groove 911 through the second air bag 93, so that the air groove 911 expands outward, and forms a trumpet-shaped air cushion 91 support on the outside of the fetus's neck, which can increase the time for the fetal head to be delivered when the buttocks are delivered first, so as to reduce the situation of dystocia. At the same time, during the movement of the fetal head during delivery, the birth canal can slowly expand outward, thereby reducing the pain of delivery for the mother.
