Description

Technical Field

[0001] The present invention relates to the technical field of painless delivery posture assistance, in particular to a painless delivery posture assistance device. Background Art

[0002] Painless childbirth, as an advanced method of childbirth, aims to use various scientific and effective methods to significantly reduce the pain during childbirth. Throughout the process, we always adhere to the vital principle of maintaining the safety of mothers and fetuses. Through the correct use of drugs by professional doctors, the transmission of pain nerves during childbirth can be cleverly blocked without affecting the regular contraction of the uterus. For mothers, childbirth is a challenging journey. Severe pain not only brings great physical pain to mothers, but may also cause psychological fear and tension. The emergence of painless childbirth has brought good news to mothers. On the basis of strictly following the safety principles, doctors will accurately select appropriate drugs and doses according to the specific situation of the mother. These drugs will not interfere with the normal regular contraction of the uterus, ensuring that the childbirth process can proceed naturally and smoothly. When the drugs work, the transmission of pain nerves is effectively blocked, and the pain felt by the mother is significantly reduced. This allows the mother to welcome the arrival of new life in a relatively comfortable state. At the same time, since there is no adverse effect on uterine contraction, the environment of the fetus in the mother remains stable. The regular contraction of the uterus continues to push the fetus through the birth canal, ensuring the normal progress of delivery. With its scientific methods and high attention to safety, painless delivery provides a more humane delivery option for mothers. It not only reduces the pain of mothers, but also ensures the safety of mothers and fetuses.

[0003] During the process of injecting the anesthetic needle for painless delivery, there are requirements for the body position of the parturient. At this time, the parturient is required to lie on her side and bend her body, presenting an arched posture like a shrimp. Such a body position can provide the best physical conditions for the accurate injection of the anesthetic needle, ensuring that the anesthetic can smoothly reach the predetermined position and exert the best analgesic effect. However, in the actual injection process, the parturient may shake her body or move unconsciously when she is nervous or in pain, and the injection position of the parturient cannot be kept stable, which will not only bring great difficulties to the injection operation, but also affect the injection effect, which may cause the anesthetic to not be accurately injected into the target area.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-10 The present invention provides a technical solution: a painless delivery posture auxiliary device, including a fixing rod 1, an adjusting rod 2, a locking ring 3, a splint 4, a fixing shell 5, a cylinder 6, a top plate 7, a telescopic rod 8, a connecting shell 9, a rotating cylinder 10, a bidirectional motor 11, a threaded rod 12, a connecting rod 13, a fixing plate 14, a limiting rod 15, a connecting piece 16, an arc plate 17, a pillow 18, a limiting rod 2 19, an arc groove plate 20, a supporting rod 21, a connecting sleeve 22, an elastic band 1 23, a tensioning rope 1 24, an elastic band 2 25, and a tensioning rope 26.

[0042] Embodiment 1: The painless delivery posture auxiliary device is provided with a clamping and fixing structure so that the device is clamped and installed on the edge of the bed board, specifically:

[0043] The fixed rod 1 is arranged in a C-shaped structure, and also includes a telescopic rod 8, which is rotatably mounted on the outer surface of the fixed rod 1, and the fixed rod 1 is connected with a clamping and fixing structure, which can be fixedly clamped at the bedside through a clamping plate 4 and a top plate 7, and the clamping and fixing structure includes an adjusting rod 2, both ends of the fixed rod 1 are fixedly connected with the adjusting rod 2, and a locking ring 3 is rotatably mounted on the outer surface of the adjusting rod 2, and a clamping plate 4 is fixedly mounted on the lower end of the adjusting rod 2, and a fixing shell 5 is fixedly connected to the lower surface of the clamping plate 4, and a cylinder 6 is fixedly mounted on the bottom surface of the inner wall of the fixing shell 5, and the upper end of the cylinder 6 is fixedly connected with the shaft of the lower surface of the top plate 7, and an opening is provided on the lower surface of the inner wall of the clamping plate 4, and the opening is slidably connected with the shaft of the lower surface of the top plate 7, and two telescopic rods 8 are symmetrically mounted;

[0044] When the painless delivery posture auxiliary device is used, it first needs to be fixed on the bed board of the parturient. The initial state is as follows: Figure 2As shown, the groove of the splint 4 clamps the edge of the bed board, and the parturient lies on her side with her back to the splint 4, and then Figure 4 As shown, a cylinder 6 is fixedly installed inside a fixed shell 5 fixedly connected to the lower surface of the splint 4. When the cylinder 6 is turned on, the push rod of the cylinder 6 will push the top plate 7 to move upward, so that the bed board is directly clamped more tightly between the bottom surface of the inner wall of the splint 4 and the upper surface of the top plate 7. Then an adjusting rod 2 is installed on the upper surface of the splint 4, which can be adjusted according to the height of the parturient when lying on her side. When adjusting, the locking ring 3 is rotated to loosen the locking ring 3, and the adjusting rod 2 can be extended and retracted. When the height is appropriate, the locking ring 3 is rotated to lock the adjusting rod 2. At this time, the parturient is facing away from the device, and since the telescopic rod 8 is rotatably installed on the outer surface of the fixed rod 1, the telescopic rod 8 is rotated. At this time, Figure 1 As shown, the part connected with the telescopic rod 8 will be in front of the parturient, so as to assist the parturient in body positioning when necessary.

[0045] Embodiment 2: The painless delivery posture auxiliary device is also provided with a posture auxiliary structure, so that the neck and legs of the parturient are relatively restrained to form a shrimp position to avoid shaking, specifically:

[0046] The telescopic rod 8 is also connected to a posture auxiliary structure, which can assist in restraining the neck and legs through the arc plate 17 and the arc groove plate 20. The auxiliary structure includes a connecting shell 9, the front surface of the connecting shell 9 is fixedly connected to the telescopic rod 8, and the inner wall surface of the connecting shell 9 is fixedly installed with a bidirectional motor 11. Both ends of the bidirectional motor 11 are fixedly installed with a rotating cylinder 10, and the rotating cylinder 10 is rotatably installed on the side surface of the connecting shell 9. The internal thread of the rotating cylinder 10 is connected to a threaded rod 12, and the other end of the threaded rod 12 is rotatably installed on the side surface of the fixed plate 14. The side surface of the fixed plate 14 is fixedly installed with a limit rod 15, and the other end of the limit rod 15 slides through the side surface of the connecting shell 9. The fixed plate 14 is symmetrically provided with two, one of which is fixed A limiting rod 19 is fixedly installed on the side surface of the fixed plate 14, and the limiting rod 19 slides through the other side surface of the connecting shell 9. The other side surfaces of the two fixed plates 14 are fixedly installed with a connecting rod 13, and a connecting piece 16 is slidably installed on the lower end of the connecting rod 13, and an arc plate 17 is fixedly installed on the lower end of the connecting piece 16. An arc slot plate 20 is fixedly installed on the lower end of another connecting piece 16, and a cushion 18 is fixedly installed on the inner side surface of the arc plate 17. The arc slot plate 20 is set to a 3-shaped structure, and the inner wall surface of the arc slot plate 20 is installed with anti-skid particles. The limiting rod 15 and the arc plate 17 are on the same side, the limiting rod 2 19 and the arc slot plate 20 are on the same side, and the limiting rod 15 and the limiting rod 2 19 penetrate the side positions of the connecting shell 9 and are staggered;

[0047] Furthermore, when assisting the parturient to maintain the posture, first, the telescopic rod 8 is extended and retracted to change the length, so that the arc plate 17 and the arc groove plate 20 correspond to the parturient's neck and legs respectively. When the arc groove surface of the arc plate 17 is sleeved on the rear surface of the parturient's neck, the parturient's head will be resting on the upper surface of the cushion 18, making the parturient's head more comfortable. Then, the arc groove plate 20 is set to a 3-shaped structure, and the grooves will correspond to the posterior bending parts of the knees of the two legs respectively. The elastic band 23 will be between the two legs. Then, the connecting shell 9 to which the telescopic rod 8 is fixedly connected is fixedly installed with a bidirectional motor 11, such as Figure 6 As shown, both ends of the bidirectional motor 11 are fixedly connected with the rotating cylinder 10, and the threaded rod 12 is threadedly connected inside the rotating cylinder 10, so when the bidirectional motor 11 is turned on, the rotating cylinder 10 will rotate, and the threaded rod 12 will rotate and move in the direction of the connecting shell 9. Since the other end of the threaded rod 12 is rotatably mounted on the side surface of the fixed plate 14, and the fixed plate 14 is symmetrically arranged with two corresponding to the fixed plate 14, the two fixed plates 14 are respectively connected with the limiting rod 2 19 and the limiting rod 1 15, and the limiting rod 2 19 and the limiting rod 1 15 are staggered through the side surface of the connecting shell 9, so the limiting rod 2 19 and the limiting rod 1 15 can prevent the threaded rod 12 from driving the fixed plate 14 when rotating, and the threaded rod 12 will drive The fixed plate 14 moves, so that the connecting rod 13 fixedly installed on the other side surface of the two fixed plates 14 respectively drives the arc plate 17 and the arc groove plate 20 to move relative to each other, and the connecting piece 16 fixedly connected on the upper surface of the arc plate 17 and the arc groove plate 20 slides through the lower end of the connecting rod 13, so that the position of the arc plate 17 and the arc groove plate 20 can be adjusted according to the different body shapes of the parturient. After the arc plate 17 and the arc groove plate 20 are driven to move, the parturient's back will be arched to form a shrimp-like position. The arc plate 17 and the arc groove plate 20 can limit the parturient's shaking, so that the parturient's body position is better maintained, stable support can be provided for the parturient, her physical burden is reduced, and comfort is improved. It can help the parturient reduce muscle fatigue and discomfort, and reduce the psychological pressure of the parturient.

[0048] Embodiment 3: The painless delivery posture auxiliary device is also provided with a tightening structure, so that the arc plate 17 and the arc groove plate 20 fit the parturient more closely, specifically:

[0049] The connecting shell 9 is also connected to a tightening structure, which can tighten the lower ends of the arc plate 17 and the arc slot plate 20 by rotating the support rod 21. The tightening structure includes an elastic band 25, one end of which is fixedly installed on the side surface of the cushion 18, and the other end of the elastic band 25 is fixedly connected to a tensioning rope 26, which is installed in a winding manner on the outer surface of the support rod 21. A connecting sleeve 22 is fixedly installed on the outer surface of the support rod 21, and two connecting sleeves 22 are vertically arranged. An elastic band 23 is connected to the side surface of the arc slot plate 20, and the elastic band 23 is fixedly connected to a tensioning rope 24, which is installed in a winding manner on the outer surface of the support rod 21. The side surface of the connecting sleeve 22 is provided with an opening, and the side surface openings of the two connecting sleeves 22 correspond to the corresponding tensioning rope 24 and the tensioning rope 26 respectively.

[0050] Further, the elastic band 25 connected to the side surface of the pillow 18 is connected to a tension rope 26, such as Figure 3 As shown, the elastic band 1 23 connected to the side surface of the arc groove plate 20 is connected with a tensioning rope 1 24, and the other ends of the tensioning rope 26 and the tensioning rope 1 24 are both wrapped around the outer surface of the support rod 21. When the telescopic rod 8 rotates, the support rod 21 will reach the front side of the belly of the parturient, and then the lower end of the support rod 21 will be on the bed surface to support the connecting shell 9. Then the support rod 21 rotates, and at the same time, the tensioning rope 1 24 and the tensioning rope 26 are wrapped around one end of the outer surface of the support rod 21 and pressed down, which will cause the tensioning rope 1 24 and the tensioning rope 26 to detach downward from the slots of the connecting sleeve 22, and then be wrapped in the corresponding support rod 21 inside the connecting sleeve 22, so that the tensioning rope 1 24 and the tensioning rope 26 tighten the arc plate 17 and the arc groove plate 20, which fits the parturient more closely, further assists in fixing the parturient's body position, ensures that the auxiliary restraint is more firm, and effectively prevents the parturient from breaking free from the restraint due to body movement during the injection process, thereby ensuring the stability of the injection position.

[0051] Working principle: When using the painless delivery position assisting device, a clamping and fixing structure is provided to fix the splint 4 on the edge of the bed board, which is simple to operate and convenient for assembly and disassembly. A position assisting structure is also provided to control the arc plate 17 and the arc groove plate 20 to restrain the parturient and reduce the shaking of the parturient. A tightening structure is also provided to strengthen the control of the arc plate 17 and the arc groove plate 20 on the parturient's position, thereby increasing the overall practicality.
