Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an amniotic membrane breaking device capable of hiding the piercing needle. BACKGROUND

[0002] Normal rupture of the amniotic membrane occurs when the cervix is almost fully dilated or fully dilated during the first stage of labor, at which time the contractions continue to strengthen and the pressure in the amniotic cavity continues to increase. When the pressure in the amniotic cavity increases to a certain extent, the amniotic membrane will naturally rupture. However, during normal childbirth, the amniotic membrane may not rupture as expected during labor. In order to ensure the normal birth of the fetus, artificial puncture of the amniotic membrane is required. Conventional membrane breakers generally use a needle to puncture the membrane. The puncture needle is inserted into the vagina, and then directly punctures the amniotic membrane to allow the amniotic fluid to be discharged normally. Although the above device can achieve the effect of artificial membrane rupture, on the one hand, the puncture needle lacks protection when it enters the vagina, which can easily cause scratches on the inner wall of the vagina. On the other hand, after artificial rupture of the amniotic membrane, the amniotic membrane remains in the vagina, causing an impact.

DETAILED DESCRIPTION

[0028] The present application will be described in detail below with reference to the accompanying drawings.

[0029] A kind of amniotic membrane breaking device that can hide lancet, as shown in Figure 1 And Figure 2 It includes base 1, fixed assembly 2, first fixed frame 3, bracket 4, spring 5, membrane breaking mechanism 6 and disinfection mechanism 7, the lower side of the front part of base 1 is connected with left and right two fixed assemblies 2, fixed assembly 2 includes guide rod, fixing piece and buffer, the lower side of the front part of base 1 is connected with two guide rods that are symmetrical left and right, the fixed piece is slidably connected between the guide rods, the fixed piece and base 1 are connected with two buffers, the upper side of the front part of base 1 is connected with the first fixed frame 3 that is symmetrical left and right by bolt, the first fixed frame 3 is slidably connected with bracket 4, bracket 4 and first fixed frame 3 are connected with spring 5, base 1 is equipped with membrane breaking mechanism 6, base 1 is equipped with disinfection mechanism 7.

[0030] Amniotic membrane will usually rupture normally when the fetus enters the birth canal, but there will be some amniotic membrane difficult to break spontaneously, in order to ensure the safety of the fetus and the smooth birth of the fetus, artificial puncture is needed to break the amniotic membrane, first, the base 1 is fixed and installed by the fixed assembly 2, the device is erected, then the membrane breaking mechanism 6 is supported and buffered by the cooperation between the bracket 4 and the spring 5, the stability is improved, and the membrane breaking mechanism 6 is disinfected by using the disinfection mechanism 7, then the membrane breaking mechanism 6 is used to enter the vagina of the puerpera, the amniotic membrane is broken, and the rupture of amniotic fluid is guided.

[0031] As Figure 1 , Figure 3 And Figure 4As shown, the membrane breaking mechanism 6 comprises a connecting frame 61, a roller 62, a sliding plate 63, an inner cylinder 64, an outer cylinder 65, a rotating rod 66, a knife holder 67, a knife 68 and a clamping block 69. The rear upper sides of the left and right parts of the base 1 are connected by bolts and have the connecting frame 61. The upper parts of the connecting frame 61 are rotatably connected with the roller 62. The outer cylinder 65 is placed between the top parts of the bracket 4. The outer cylinder 65 is slidably connected with the inner cylinder 64. The rear lower side of the inner cylinder 64 is connected with the sliding plate 63. The sliding plate 63 is slidably connected with the roller 62. The rotation of the roller 62 can drive the sliding plate 63 to move. The inner cylinder 64 is rotatably connected with the rotating rod 66. The front side of the rotating rod 66 is connected with the knife holder 67. The knife holder 67 is connected with the knife 68. The knife 68 can hook the amniotic membrane while breaking it, so as to take out the amniotic membrane. The inner cylinder 64 and the outer cylinder 65 are slidably connected with the clamping block 69.

[0032] It should be noted that when artificial puncture is needed to break the amniotic membrane, the outer cylinder 65 needs to be sent into the vagina of the puerpera first. At this time, due to the limited length of the vagina, part of the outer cylinder 65 will still be outside the body of the puerpera. With the movement of the outer cylinder 65 to the position, the clamping block 69 is slid upward, so that the clamping block 69 no longer locks the inner cylinder 64. Then press the outer cylinder 65 and rotate the roller 62, so that the roller 62 drives the sliding plate 63 to slide forward, the sliding plate 63 drives the inner cylinder 64 to slide forward, and then the knife holder 67 drives the knife 68 to slide forward. After the knife 68 contacts the amniotic membrane, it will puncture and break the amniotic membrane. It should be particularly noted that the rotating rod 66 needs to be continuously rotated while the amniotic membrane is broken, so that the knife 68 is continuously rotated and then hooks the amniotic membrane. Then, when the outer cylinder 65 and the inner cylinder 64 leave the body of the puerpera, the amniotic membrane is hooked and taken out. In summary, the outer cylinder 65 drives the inner cylinder 64 to approach the amniotic membrane, and at the same time the outer cylinder 65 shields the inner cylinder 64, so as to avoid the knife 68 scratching the inner wall of the vagina of the puerpera during the process of entering the body of the puerpera. During the process of puncturing and breaking the amniotic membrane, the rotating rod 66 is rotated to enable the knife 68 to hook the amniotic membrane, so as to take out the amniotic membrane after breaking, and avoid the amniotic membrane remaining in the body of the puerpera.

[0033] As shown in Figure 1 and Figure 5 The disinfection mechanism 7 comprises a first guide frame 71, a sliding frame 72, a mounting ring 73 and a disinfecting sponge 74. The front upper side of the base 1 is connected by bolts and has the first guide frame 71. The left and right parts of the first guide frame 71 are slidably connected with the sliding frame 72. The upper parts of the sliding frame 72 are connected with the mounting ring 73 on the side close to each other. The side close to each other of the mounting ring 73 is connected with the disinfecting sponge 74. The disinfecting sponge 74 is used for wiping and disinfecting the outer cylinder 65.

[0034] It should be noted that before the outer tube 65 enters the inside of the maternal vagina, in order to ensure the health and safety of the mother, the outer tube 65 needs to be disinfected. First, push the sliding frame 72 to the side close to each other, so that the mounting ring 73 drives the disinfection sponge sheet 74 to approach each other, and wipe the surface of the outer tube 65 for disinfection. After disinfection, slide the sliding frame 72 to the side away from each other and reset. As described above, by pushing the sliding frame 72, the mounting ring 73 drives the disinfection sponge sheet 74 to move, thereby wiping the surface of the outer tube 65 for disinfection, avoiding bacteria on the outer tube 65 entering the maternal vagina, causing bacterial infection.

[0035] As Figure 1 , Figure 6 and Figure 7 It also includes a fixing mechanism 8, which includes a square box 81, a wedge block 82 and a handle 83. The outer tube 65 is slidably connected to the rear of the square box 81. The square box 81 is connected to the front of the wedge block 82. The wedge block 82 is used to push the clamping block 69. The handle 83 is connected to the rear side of the square box 81. The handle 83 is convenient for pulling the square box 81.

[0036] It should be noted that in order to facilitate medical staff to pull up the clamping block 69 and unlock the inner tube 64, the handle 83 can be directly pulled back, so that the square box 81 drives the wedge block 82 to move backward, and then the wedge block 82 contacts the clamping block 69 and pushes the clamping block 69, so that the clamping block 69 slides upward, achieving the effect of quickly unlocking the inner tube 64. As described above, by pulling the handle 83 backward, the square box 81 drives the wedge block 82 to move backward, thereby quickly pulling out the clamping block 69 upward, and quickly unlocking the inner tube 64.

[0037] As Figure 1 and Figure 8 It also includes a trigger mechanism 9, which includes a fixed plate 91, a sliding rod 92, a second guide frame 93 and a second fixed frame 94. The fixed plate 91 is connected to the front lower side of the outer tube 65 by bolts. The fixed plate 91 is connected to the bottom of the two symmetrical sliding rods 92. The second fixed frame 94 is connected to the middle position of the sliding frame 72. The second guide frame 93 is connected to the side close to each other of the second fixed frame 94. The second guide frame 93 is slidably connected with the adjacent sliding rod 92.

[0038] With the forward movement of the outer cylinder 65, the fixed plate 91 is moved forward, so that the sliding rod 92 is moved forward, and at this time, since the second guide frame 93 is slidably connected with the adjacent sliding rod 92, with the forward movement of the sliding rod 92, the second guide frame 93 drives the second fixed frame 94 to approach each other, so that the sliding frame 72 slides to the side where the sliding frames 72 approach each other, thereby wiping and disinfecting the outer cylinder 65 as a whole, improving the disinfection efficiency and reducing manual contact. In summary, by moving the outer cylinder 65 forward to drive the fixed plate 91 to move forward, the second guide frame 93 is driven by the sliding rod 92 to slide to the side where the second guide frames 93 approach each other, and then the sliding frame 72 approaches each other, so that the disinfectant sponge block can automatically and comprehensively wipe the outer cylinder 65.

[0039] As shown in Figure 3 and Figure 9 , it also includes a discharge mechanism 10, the discharge mechanism 10 includes a fixed ring 101 and a scraper 102, the rotating rod 66 is connected with three fixed rings 101, the fixed ring 101 is connected with a scraper 102, and the scraper 102 is used to assist in discharging amniotic fluid.

[0040] It should be noted that after the device is used to puncture and rupture the amniotic membrane, the amniotic fluid flows out through the inner cylinder 64, and in this process, with the continuous rotation of the rotating rod 66, the fixed ring 101 drives the scraper 102 to rotate continuously, thereby guiding the amniotic fluid to flow out quickly through the inner cylinder 64, improving the efficiency of discharging amniotic fluid. In summary, by rotating the rotating rod 66 to drive the scraper 102 to rotate quickly, the amniotic fluid is discharged, and the efficiency of discharging the amniotic fluid is improved.

[0041] As shown in Figure 1 and Figure 10 , it also includes a feeding mechanism 11, the feeding mechanism 11 includes a third fixed frame 111, a rack 112, a gear 113 and a handle 114, the sliding plate 63 is connected with the third fixed frame 111 on the left and right sides through bolts, the third fixed frame 111 is connected with the rack 112 on the bottom through bolts, the roller 62 is connected with the gear 113 on the left and right sides, the gear 113 can be meshed with the adjacent rack 112, and the handle 114 is connected with the gear 113 on the side away from each other.

[0042] It should be noted that in order to ensure the accuracy of the travel of the outer cylinder 65 and the inner cylinder 64 to the vagina of the puerpera, the handle 114 can be directly rotated to rotate the gear 113, so that the rack 112 starts to drive the third fixed frame 111 to move forward, and then the sliding plate 63 moves forward. Through the cooperation between the gear 113 and the rack 112, the travel distance of the outer cylinder 65 and the inner cylinder 64 can be easily controlled, and the accuracy is improved. In summary, through the cooperation between the rack 112 and the gear 113, the distance of the inner cylinder 64 and the outer cylinder 65 during the travel process can be accurately controlled, and the fetus in the amniotic fluid is prevented from being hurt by the cutter 68.
