Description

Technical Field

[0001] The present invention relates to the technical field of fetal heart rate monitoring devices, and in particular to an intelligent fetal heart rate monitoring device for obstetrics and gynecology. Background Art

[0002] In the late pregnancy, it is necessary to regularly monitor the fetal heart rate of pregnant women in order to timely discover possible problems that may occur in the growth and development of the fetus. When using the existing fetal heart rate monitoring device, the fetal heart rate monitoring probe and the uterine contraction monitoring probe are usually fixed to the abdomen of the pregnant woman through two elastic bands wrapped around the waist of the pregnant woman. When placing the elastic bands, the pregnant woman is usually required to lie flat on the monitoring bed, and the pregnant woman needs to lift her waist to separate her body from the monitoring bed before the two elastic bands can be placed under the pregnant woman. For pregnant women in the late pregnancy, the abdomen is relatively heavy, so when lifting the waist, not only will the pregnant woman feel tired, but also increase the pressure on the spine and waist of the pregnant woman. At the same time, in the process of making this action, without proper support, the pregnant woman will also face the risk of falling and losing balance, causing unnecessary pressure on the abdomen of the pregnant woman, affecting the safety of the fetus. At the same time, the entire monitoring process needs to last for 10 to 20 minutes. In the case of improper operation by medical staff, the elastic band will also cause a sense of pressure on the abdomen and waist of the pregnant woman, causing discomfort to the pregnant woman.

DETAILED DESCRIPTION

[0053] 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.

[0054] The present invention proposes an intelligent fetal heart rate monitoring device for obstetrics and gynecology, such as Figure 1-Figure 5 As shown, it includes: a monitoring host 101, which is electrically connected to two monitoring probes 1 through wires; a mounting shell 2, which has two parts and is respectively fixed to adjacent monitoring probes 1, and the mounting shell 2 is provided with a moving shell 3, the moving shell 3 is fixed with a rubber ring 4, and a moving ring 5 is slidably connected inside the moving shell 3; a plurality of moving blocks 6, which are respectively fixed to adjacent moving rings 5, and the moving blocks 6 are slidably connected to the adjacent moving shells 3; a first driving ring 7, which has two parts and is respectively rotatably connected to adjacent moving shells 3, and an internal thread is provided inside the first driving ring 7, and the first driving ring 7 is threadably matched with the adjacent moving block 6 through the internal thread thereon.

[0055] In the above scheme, the two monitoring probes 1 are used to detect fetal heart rate and uterine contraction respectively. Figure 1 The monitoring probe 1 on the left side is used to detect the fetal heart rate, and the one on the right side is used to detect uterine contractions. The two mounting shells 2 are respectively installed on the upper sides of adjacent monitoring probes 1. The movable shell 3 is fixedly connected to the adjacent mounting shell 2, and the height of the lower side of the rubber ring 4 is lower than the height of the lower side of the adjacent monitoring probe 1, so as to fix the monitoring probe 1 on the abdomen of the pregnant woman. The specific number of movable blocks 6 can be selected when producing the device. The figure and the text both take the example of one movable block 6 being fixedly connected to each of the two movable rings 5. In actual production, the staff can appropriately increase the number. The first drive ring 7 is located on the upper side of the adjacent movable shell 3.

[0056] Considering that during fetal heart rate monitoring for pregnant women, the pregnant women need to lift their waists before the elastic band required for monitoring can be placed under their bodies. The abdomen of pregnant women in the late pregnancy is very heavy, which will make them feel tired and increase the pressure on their spine and waist. It may even cause unnecessary pressure on the abdomen, affecting the safety of the fetus. In this regard, the present invention solves this problem through the following measures:

[0057] The following description is made by taking the movement process of the part on the right monitoring probe 1 as an example:

[0058] After the staff adjusts the position of the monitoring probe 1 (that is, when the position of the right monitoring probe 1 is adjusted to the position where uterine contractions can be monitored), the lower side of the monitoring probe 1 and the lower side of the rubber ring 4 are tightly fitted to the skin of the pregnant woman. At the same time, the lower side of the rubber ring 4 is deformed by the shape of the skin on the pregnant woman's abdomen, so that the rubber ring 4 is tightly attached to the skin on the pregnant woman's abdomen. At this time, the movable shell 3, the rubber ring 4, the movable ring 5 and the skin on the pregnant woman's abdomen cooperate with each other to form a closed cavity (hereinafter referred to as a sealed cavity as an example). Then the staff rotates the first driving ring 7, and the first driving ring 7 drives the movable block 6 to move upward, and the movable block 6 drives the movable ring 5 to move upward in the movable shell 3, so that negative pressure is generated in the sealed cavity, and then the right monitoring probe 1 and other parts thereon are adsorbed on the pregnant woman's abdomen, completing the fixation of the right monitoring probe 1, making the entire fixing process faster and more convenient, and at the same time, the pregnant woman no longer needs to lift her waist or use elastic bands to fix, thereby improving the comfort of the pregnant woman during the monitoring process.

[0059] After the monitoring probe 1 on the right side is fixed, the staff fixes the monitoring probe 1 on the right side according to the above operation and monitors the fetal heart rate. After the monitoring is completed, the staff rotates the two first drive rings 7 in reverse in turn and resets the two movable rings 5 ​​to the initial position, that is, removes the two monitoring probes 1 for subsequent continued use.

[0060] Further, such as Figure 3-Figure 5 As shown, the rubber ring 4 is located outside the moving shell 3, and the rubber ring 4 is in a truncated cone shape. The distance between the circumference of the rubber ring 4 and its central axis gradually decreases from bottom to top. The specific working principle of the rubber ring 4 can refer to the working principle of the suction cup.

[0061] Furthermore, Figure 5-Figure 7As shown, it also includes: two unlocking components, the two unlocking components are respectively arranged on adjacent moving shells 3, the unlocking components are used to change the sealing state between the moving ring 5 and the moving shell 3, the unlocking components include: a rotating ring 8, which is rotatably connected to the adjacent moving ring 5, the rotating ring 8 is slidably and rotatably connected to the adjacent moving shell 3, the moving ring 5 and the rotating ring 8 are both provided with a plurality of exhaust holes 9, the exhaust holes 9 on the rotating ring 8 are communicated and matched with adjacent exhaust holes 9 on the adjacent moving ring 5; slide grooves 10, the number of which is consistent with the number of moving blocks 6 on the adjacent moving rings 5, are arranged on the rotating ring 8, and the moving blocks 6 are located in the adjacent slide grooves 10.

[0062] In the above scheme, the rotating ring 8 is located on the upper side of the adjacent moving ring 5. The specific number of the exhaust holes 9 can be specifically selected by the staff, but the number of the exhaust holes 9 on the moving ring 5 and the rotating ring 8 must be consistent; initially, the exhaust holes 9 on the moving ring 5 are not connected to the adjacent exhaust holes 9 on the adjacent rotating ring 8; the rotating ring 8 rotates counterclockwise (in Figure 1 Taking the top view as an example), the exhaust hole 9 on it can be connected with the adjacent exhaust hole 9 on the adjacent movable ring 5.

[0063] Further, such as Figure 6-Figure 8 As shown, the unlocking component also includes: a positioning block 11, which is fixed to the rotating ring 8 and is located in the slide groove 10; a first elastic member 12, which is fixed between the positioning block 11 and the adjacent movable ring 5; a limit block 13, which is slidably connected to the adjacent movable block 6, and the limit block 13 is limitedly matched with the positioning block 11; a trigger component, which is arranged on the mounting shell 2, and the trigger component is used to change the position of the adjacent limit block 13.

[0064] In the above scheme, the first elastic member 12 is a tension spring, and initially, the first elastic member 12 is in a stretched state, and the retractable length of the first elastic member 12 is less than the sum of the projection lengths of the inclined surface on the limit block 13 and the inclined surface on the adjacent positioning block 11 on the same horizontal plane. Even after the first elastic member 12 drives the adjacent positioning block 11 to move, the inclined surface on the positioning block 11 is still in contact with the inclined surface on the adjacent limit block 13; initially, the height of the highest point of the inclined surface on the limit block 13 is lower than the height of the lowest point of the inclined surface on the adjacent positioning block 11, that is, initially, the vertical surface of the limit block 13 is in contact with the vertical surface of the adjacent positioning block 11.

[0065] Further, such as Figure 6-Figure 8 As shown, the moving block 6, the slide groove 10, the positioning block 11 and the limit block 13 are all arc-shaped, and the centers of the circles where the four arcs are located are located on the same central axis as the center of the adjacent moving shell 3, and the arc length of the slide groove 10 is greater than the arc length of the moving block 6.

[0066] In the above scheme, the shapes of the moving block 6, the slide groove 10, the positioning block 11 and the limit block 13 are limited so that the four can rotate together with the adjacent rotating ring 8; ensuring that the rotating ring 8 can rotate normally and avoiding the moving block 6 from hindering the rotation of the rotating ring 8.

[0067] Further, such as Figure 5 and Fig. 9 As shown, the trigger assembly includes: a first guide wheel 14, which is rotatably connected to the adjacent mounting shell 2; a liquid storage shell 15, which is fixedly connected to the adjacent mounting shell 2; a piston rod 16, which is slidably connected in the liquid storage shell 15, and a second elastic member 161 is fixedly connected between the piston rod 16 and the liquid storage shell 15; a second guide wheel 17, which is rotatably connected to the piston rod 16, and the wire on the monitoring probe 1 passes around the second guide wheel 17 and the first guide wheel 14; a hydraulic push rod 18, which is fixedly connected to the adjacent moving block 6, and the telescopic end of the hydraulic push rod 18 is in contact with the adjacent limit block 13, and the fixed part of the hydraulic push rod 18 is connected to the adjacent liquid storage shell 15 through a hose.

[0068] In the above scheme, the second guide wheel 17 is located on one side of the adjacent first guide wheel 14, and the two are initially in a parallel state. The wire on the monitoring probe 1 first bypasses the upper side of the first guide wheel 14 and then bypasses the lower side of the second guide wheel 17 (such as Figure 5 As shown); the liquid storage shell 15 is filled with hydraulic oil, the second elastic member 161 is a spring, which is used to drive the piston rod 16 to reset after moving; the hydraulic push rod 18 is used to drive the limit block 13 to move upward.

[0069] Considering that after the two monitoring probes 1 are fixed on the abdomen of the pregnant woman, when the wires on the monitoring probes 1 are accidentally pulled, the wires will exert tension on the monitoring probes 1, which will not only cause the position of the monitoring probes 1 to shift, thereby affecting the accuracy of the monitoring data, but also seriously cause a sense of oppression on the abdomen of the pregnant woman, and also bring additional psychological pressure to the pregnant woman, worrying about whether it will have an adverse effect on the fetus. In this regard, the present invention solves this problem through the following measures:

[0070] The following description is based on the case where the wire on the right monitoring probe 1 is pulled as an example:

[0071] The wire is pulled to drive the second guide wheel 17 to move upward, and the second guide wheel 17 drives the piston rod 16 to move upward synchronously, and the piston rod 16 squeezes the hydraulic oil in the liquid storage shell 15, so that the hydraulic oil in the liquid storage shell 15 flows into the fixed part of the hydraulic push rod 18 through the hose, and then the telescopic part of the hydraulic push rod 18 drives the limit block 13 to move upward synchronously, until the vertical surface of the limit block 13 loses contact with the vertical surface of the positioning block 11, and the tension on the first elastic member 12 is reduced. At this time, the first elastic member 12 drives the positioning block 11 to move, and the positioning block 11 drives the rotating ring 8 to rotate counterclockwise (with Figure 1Taking the top view as an example), during the movement of the positioning block 11, the inclined surface of the positioning block 11 squeezes the inclined surface on the limiting block 13, so that the limiting block 13 moves upward due to the squeezing force.

[0072] During the counterclockwise rotation of the rotating ring 8, the exhaust holes 9 on the rotating ring 8 are connected with the adjacent exhaust holes 9 on the adjacent moving ring 5, so that the outside air can enter the sealed cavity along the exhaust holes 9 on the rotating ring 8 and the adjacent moving ring 5, so that the pressure in the sealed cavity gradually increases, and then gradually reduces the fixing effect of the rubber ring 4 on the monitoring probe 1, until the pressure in the sealed cavity is equal to the atmospheric pressure, the monitoring probe 1 on the right side is completely separated from the pregnant woman, that is, when the wire is pulled, the monitoring probe 1 can be quickly separated from the pregnant woman's body, avoiding the monitoring probe 1 from causing a sense of pressure on the pregnant woman's abdomen or causing pain to the pregnant woman's abdomen, and even causing adverse effects on the fetus in the pregnant woman's abdomen.

[0073] During the process of separating the monitoring probe 1 on the right side from the abdomen of the pregnant woman, the wire is pulled and drives the monitoring probe 1 on the right side to move synchronously. At this time, the pulling force generated by the wire on the second guide wheel 17 gradually decreases, so that the second elastic member 161 drives the adjacent piston rod 16 and the second guide wheel 17 to gradually return to the initial position, and the hydraulic oil delivered to the fixed part of the adjacent hydraulic push rod 18 is re-drawn into the adjacent liquid storage shell 15, so that the telescopic end of the adjacent hydraulic push rod 18 is reset downward to the initial state. When the telescopic end of the hydraulic push rod 18 is reset downward, the telescopic end of the hydraulic push rod 18 loses contact with the adjacent limit block 13. At this time, the limit block 13 will not be reset downward under the squeezing of the adjacent positioning block 11.

[0074] After the monitoring probe 1 on the right side is separated from the abdomen of the pregnant woman and stops moving, the staff inspects the parts connected to the monitoring probe 1 on the right side. If there are damaged parts, the staff will replace them in time. If there are no damaged parts, the staff will maintain the parts on the monitoring probe 1 and then press the limit block 13 downward to make the inclined surface of the limit block 13 squeeze the positioning block 11, so that the positioning block 11 drives the adjacent rotating ring 8 to rotate synchronously clockwise, and stretches the adjacent first elastic member 12 to store force. At the same time, during the clockwise rotation of the rotating ring 8, the exhaust hole 9 on the rotating ring 8 and the adjacent exhaust hole 9 on the moving ring 5 are gradually misaligned, that is, the rotating ring 8 gradually blocks the exhaust hole 9 on the adjacent moving ring 5, until the limit block 13 moves downward to the initial position (when the limit block 13 contacts the telescopic end of the adjacent hydraulic push rod 18), the staff releases the limit block 13, at this time, the positioning block 11 applies a lateral extrusion force to the adjacent limit block 13 under the action of the adjacent first elastic member 12, so that the limit block 13 cannot move upward.

[0075] Furthermore, Figure 2 and Figure 3As shown, it also includes: two U-shaped frames 19, which are respectively fixed to adjacent mounting shells 2; two fixed shells 20, which are respectively fixed to adjacent U-shaped frames 19, the fixed shells 20 are squeezed and matched with adjacent rubber rings 4, and the fixed shells 20 are slidingly connected to the adjacent movable shells 3; two threaded rods 21, which are respectively threadedly connected to adjacent U-shaped frames 19, and the threaded rods 21 are rotationally connected to the adjacent movable shells 3, and the movable shells 3 are slidingly connected to the adjacent mounting shells 2.

[0076] In the above scheme, the two U-shaped frames 19 are fixed to the adjacent mounting shells 2 by bolts; the fixed shell 20 and the adjacent U-shaped frames 19 are also fixed by bolts; by rotating the two threaded rods 21 in sequence, the two movable shells 3 can be moved upward, and the heights of the two movable shells 3 and the two rubber rings 4 can be changed, so that the lower side of the rubber ring 4 is higher than the height of the adjacent monitoring probe 1, so as to avoid the edges of the two rubber rings 4 being folded due to the friction of the pregnant woman's abdominal skin during the movement of the two monitoring probes 1, which affects the subsequent use of the two rubber rings 4. After adjusting the position of the monitoring probe 1, the staff rotates the threaded rod 21 in the opposite direction to reset the adjacent movable shells 3 downward, that is, the adjacent rubber rings 4 are moved downward to a position that fits the pregnant woman's abdominal skin, and the monitoring probe 1 is fixed to the pregnant woman's abdomen according to the above operation.

[0077] Further, such as Figure 2 , Figure 3 , Fig.10 and Fig.11 As shown, it also includes: a second drive ring 22, one of the fixed shells 20 is provided with an external thread, and the second drive ring 22 is threadedly connected to the fixed shell 20 provided with the external thread; a mounting ring 23, rotatably connected to the fixed shell 20 provided with the external thread; a first connecting rod 24, hinged to the second drive ring 22; a second connecting rod 25, rotatably connected to the mounting ring 23, and the second connecting rod 25 is limitedly matched with the fixed shell 20; a fixed plate 26, slidably connected to the second connecting rod 25, and the fixed plate 26 is hinged to the first connecting rod 24, a third elastic member 27 is fixedly connected between the fixed plate 26 and the second connecting rod 25, and the fixed plate 26 is provided with a cleaning block.

[0078] In the above scheme, an external thread is provided on the fixed shell 20 on the left; initially, the second drive ring 22 is located at the uppermost side of the fixed shell 20 on the left, the second connecting rod 25 is in a horizontal state, and the upper side of the second connecting rod 25 contacts the lower side of the fixed shell 20 on the left; the third elastic member 27 is a tension spring, and initially the third elastic member 27 is in a stretched state, and the cleaning block on the fixed plate 26 is made of a soft material, which can be a water-absorbing sponge or the like; the diameter of the fixed shell 20 is larger than the small diameter of the rubber ring 4 but smaller than the large diameter of the rubber ring 4, ensuring that the rubber ring 4 can be gathered by the squeezing force of the fixed shell 20, thereby avoiding the rubber ring 4 from affecting the movement of the fixed plate 26; during the rotation of the second drive ring 22, the mounting ring 23 is driven to rotate synchronously through the transmission of the parts thereon.

[0079] Further, such as Fig.11 As shown, the second drive ring 22 is coplanar with the upper side surface of the adjacent fixed shell 20, and the height of the outer side of the fixed shell 20 without external threads is not less than the height of the second drive ring 22, ensuring that the second drive ring 22 can drive the mounting ring 23 and other parts thereon to rotate freely when it moves downward to the extreme position.

[0080] Considering that when fetal heart rate monitoring is currently performed on pregnant women, in order to ensure the accuracy of the monitoring results, a coupling agent needs to be coated between the monitoring probe 1 and the pregnant woman's skin, and the presence of the coupling agent will affect the adhesion between the rubber ring 4 and the pregnant woman's skin, resulting in a gap between the rubber ring 4 and the pregnant woman's skin, affecting the stability of the monitoring probe 1. In this regard, the present invention solves this problem through the following measures:

[0081] After the position of the left monitoring probe 1 is adjusted, excess coupling agent will be distributed around the left monitoring probe 1. Then the staff rotates the second driving ring 22, and the second driving ring 22 drives the first connecting rod 24 to move downward synchronously. The first connecting rod 24 drives the fixing plate 26 to move downward synchronously. During the downward movement of the fixing plate 26, the tension on the third elastic member 27 gradually decreases, causing the third elastic member 27 to gradually shrink. At the same time, during the shrinkage of the third elastic member 27, the second connecting rod 25 remains in a horizontal state under the action of the third elastic member 27, and the fixing plate 26 gradually moves downward relative to the second connecting rod 25 until the third elastic member 27 shrinks to an unstretched state, and the fixing plate 26 moves downward to the extreme position relative to the second connecting rod 25.

[0082] When the fixing plate 26 moves downward to the limit position relative to the second connecting rod 25, the second driving ring 22 does not move downward to the limit position. During the continuous movement of the mounting ring 23, the second connecting rod 25 is squeezed by the fixing plate 26 and rotates around the connection with the mounting ring 23. At the same time, the second connecting rod 25 drives the fixing plate 26 to rotate synchronously, and the fixing plate 26 drives the first connecting rod 24 to rotate synchronously, reducing the angle between the first connecting rod 24 and the fixing shell 20, until the second driving ring 22 moves downward to the limit position, that is, the second driving ring 22 moves downward to the position adjacent to the fixing shell 20. When the thread loses the mating position, the second connecting rod 25 is in a vertical state and the fixed plate 26 is in a horizontal state. At this time, the height of the lower side of the cleaning block on the fixed plate 26 is lower than the height of the lower side of the adjacent monitoring probe 1. Therefore, during the rotation of the fixed plate 26, the cleaning block on the fixed plate 26 is squeezed by the pregnant woman's abdomen and deformed. After the fixed plate 26 stops moving, the cleaning block on the fixed plate 26 fits the shape of the pregnant woman's abdomen. Then the staff continues to rotate the second drive ring 22, and the second drive ring 22 drives the cleaning block on the fixed plate 26 to rotate synchronously to clean the excess coupling agent on the pregnant woman's abdomen.

[0083] After the coupling agent is cleaned, the staff will re-thread the second drive ring 22 and the external thread on the left fixed shell 20, and then rotate the second drive ring 22 in the opposite direction. The second drive ring 22 will drive the fixed plate 26 to reset upward to the initial position synchronously. Then the staff will fix the monitoring probe 1 on the left side to the abdomen of the pregnant woman according to the above operation to perform fetal heart rate detection. After the monitoring is completed, the staff will separate the two monitoring probes 1 from the abdomen of the pregnant woman according to the above operation, and clean the two monitoring probes 1 and other connections thereon for subsequent continued use.

[0084] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any modifications, uses or adaptations of the present disclosure, which follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
