Description

Technical Field

[0001] The present invention relates to the technical field of fetal heart monitoring, in particular to fetal heart monitoring auxiliary equipment. Background Art

[0002] Fetal heart rate monitoring is a very important part of pregnancy management. It is mainly used to monitor the health of the fetus in the uterus and evaluate the health of the fetus. Changes in fetal heart rate can reflect the fetus's adaptation to the intrauterine environment. Doctors usually formulate corresponding management and intervention measures based on the specific situation of the pregnant woman and the results of fetal heart rate monitoring to ensure the safety of mother and child.

[0003] Existing fetal heart monitoring equipment usually needs to use ultrasonic equipment to detect the position of the fetal heart on the surface of the pregnant woman's belly. However, before the ultrasonic detection, in order to improve the contact quality between the probe and the skin of the fetal heart point, it is usually necessary to apply electrogel on the pregnant woman's belly. However, the existing fetal heart monitoring equipment does not have electrogel application equipment, and usually needs to be applied manually. Manual application is time-consuming and labor-intensive, and manual application of electrogel usually does not clean the pregnant woman's belly. Once sweat or grease remains on the pregnant woman's belly, it will affect the conductive properties of the gel and the contact effect of the probe, thereby affecting the accuracy of monitoring. Usually, the probe of the existing fetal heart monitoring equipment does not have a disinfection mechanism. If the probe is not disinfected after monitoring a pregnant woman with skin disease, the skin virus may be transmitted to the next pregnant woman through the probe, affecting the safety of the entire equipment.

[0020] In this embodiment, when in use, the operator can adjust the entire mounting plate 4 to a position suitable for monitoring pregnant women through the frame 1. After the position adjustment is completed, the operator can control the telescopic rod 2 to extend so that the two scrapers 26 contact the belly of the pregnant woman. Then the operator can turn on the drive motor 6 to drive the threaded rod 8 to rotate. When the threaded rod 8 rotates, it will drive the entire trigger box 12 to move from left to right through the driving member 7 (refer to Figure 3 ), when the trigger box 12 moves from left to right, the operator can turn on the dual-axis motor 21, so that it drives the entire roller 28 to rotate through the rotating rod 22. When the roller 28 drives the outer cylinder 33 to rotate, under the action of centrifugal force, the outer ring 45 overcomes the pulling force of the tension spring 46 and moves to the outside of the bottom tube 44. When the outer ring 45 drives the push magnet block 47 to move to the bottom of the inner plate 41, under the repulsive magnetic force between the push magnet block 47 and the trigger magnet under the inner plate 41, The inner plate 41 will overcome the elastic force of the damping spring 43 and move upward, so that the inner hole 42 overlaps with the outer hole 40. When the inner hole 42 overlaps with the outer hole 40, a layer of detergent stored in the outer tube 33 near the liquid inlet 34, which was originally blocked by the unopened part of the inner plate 41, will be thrown into the infusion channel 38 under the action of centrifugal force, and then flow into the outside of the external throwing box 37 through the overlapping outer hole 40 and inner hole 42, and thrown to the outside of the trigger box 12 to clean the pregnant woman's belly.

[0021] Example 2: Please refer to Figure 1 - Fig.11, a plurality of retracted rods 25 are fixedly connected to both sides of the trigger box 12, and a scraper 26 is arranged at the ends of the plurality of retracted rods 25, a sliding groove 54 is provided inside the trigger box 12, a sliding plate 55 is slidably connected inside the sliding groove 54, a connecting rod 58 is arranged on the outer wall of the sliding plate 55, a massage roller 53 is rotatably arranged at the end of the connecting rod 58, a sliding magnetic block 32 is arranged on the outer side of the sliding plate 55, the magnetic poles of the reciprocating magnetic block 23 and the sliding magnetic block 32 are the same, a return spring 56 is arranged on the outer wall of the sliding plate 55, and the other end of the return spring 56 is fixedly connected to the inner wall of the trigger box 12, a disinfection box 14 is fixedly connected to the outer side of the trigger box 12, and a suction pipe 15 is arranged in communication with the inner wall of the disinfection box 14, the trigger box 12 is fixedly connected to the outer side, and the inner wall of the disinfection box 14 is connected to the trigger box 12. A disinfection mechanism is provided inside the trigger box 12, and the disinfection mechanism includes straight plates 17 arranged on both sides of the inside of the trigger box 12, a spray tube 16 is installed inside the straight plate 17, the other end of the suction tube 15 passes through the inside of the spray tube 16, and the inner side wall of the spray tube 16 is slidably connected with a push rod 19, and a pushing magnetic block 18 is provided at the end of the push rod 19. A pressing spring is sleeved on the outer side wall of the push rod 19, and a spray head is provided at the end of the spray tube 16. A one-way valve is provided inside the spray head and the inside of the suction tube 15, a probe push rod 24 is provided inside the mounting plate 4, and an ultrasonic probe 57 is provided at the end of the probe push rod 24. A side magnetic plate 13 is provided on the side of the ultrasonic probe 57, and the magnetic pole of the side magnetic plate 13 is the same as the magnetic pole of the pushing magnetic block 18.

[0022] In this embodiment, when there is detergent on the belly of a pregnant woman, the scraper 26 located on the left side of the trigger box 12 will smooth the detergent so that it can evenly clean the belly to avoid residual grease or sweat on the belly that affects the later monitoring effect. When the rotating rod 22 rotates, it will drive the reciprocating magnetic block 23 to rotate synchronously. Since the sliding plate 55 is located on the positive side of the rotating rod 22, when the rotating rod 22 drives the reciprocating magnetic block 23 to intermittently rotate to the positive side of the sliding magnetic block 32, the intermittent repulsive magnetic force and the elastic force of the reset spring 56 will work together. When the massage roller 53 is used, the sliding plate 55 drives the massage roller 53 to reciprocate in the sliding groove 54. When the massage roller 53 reciprocates, it rolls on the pregnant woman's belly. Since the massage roller 53 is provided with a large number of circular protrusions, when the massage roller 53 rolls, the pregnant woman's belly can be massaged, thereby improving the comfort of use. When the trigger box 12 cleans the pregnant woman's belly from left to right, the operator can drive the motor 6 to reverse the threaded rod 8. When the threaded rod 8 reverses, the trigger box 12 moves from right to left (refer to Figure 3), when the trigger box 12 moves from left to right, the operator can increase the rotation power of the dual-axis motor 21, so that it drives the roller 28 to rotate rapidly through the rotating rod 22. When the roller 28 rotates rapidly, the centrifugal force generated will cause the outer ring 45 to overcome the tension of the tension spring 46, and the outer ring 45 will move a greater distance to the outside of the bottom tube 44 until it approaches the plate magnet block 51. At this time, under the action of the repulsive magnetic force, the outer tube 48 will be pushed by the side push plate 50 and overcome the elastic force of the pressure spring 52, and the outer tube 48 will move to the outside of the throwing box 37. When the outer tube 48 is thrown outward When the outer side of the box 37 moves, the glue outlet hole 49 will be exposed to the outside of the external disposal box 37. When the glue outlet hole 49 is exposed to the outside of the external disposal box 37, a layer of electrogel stored near the glue inlet hole 35 of the outer tube 33 will be transported by the bottom tube 44, flow into the inner part of the outer tube 48 through the open end of the outer tube 48, and finally flow out of the external disposal box 37 through the leaking glue outlet hole 49, and the electrogel will be applied to the belly of the pregnant woman. When the electrogel is applied to the belly of the pregnant woman, the scraper 26 located on the right side of the trigger box 12 will smooth the electrogel so that the electrogel can be evenly spread on the belly of the pregnant woman to ensure the subsequent detection effect.

[0023] When the trigger box 12 moves left and right and just drives the spray barrel 16 to move to the right side of the ultrasonic probe 57, the pushing magnetic block 18 will be just located at the right side of the side magnetic plate 13. At this time, under the action of the repulsive magnetic force, the push rod 19 will be pushed into the spray barrel 16. At this time, the disinfectant in the spray barrel 16 will be sprayed out through the nozzle of the spray barrel 16 to disinfect the ultrasonic probe 57, ensuring the safety of the use of the ultrasonic probe 57. After the spray barrel 16 disinfects the ultrasonic probe 57, the trigger box 12 will drive the spray barrel 16 to continue moving. When the tube 16 moves to a position away from the direct side of the ultrasonic probe 57, the distance between the pushing magnet 18 and the side magnetic plate 13 will become farther, and the magnetic force will disappear. At this time, under the elastic force of the pressing spring, the push rod 19 will return to its original position. In the process of the push rod 19 moving outward and returning to its original position, the spray tube 16 will suck the disinfectant inside the disinfection box 14 into the spray tube 16 through the suction tube 15, which is convenient for next use. After cleaning and applying the electric gel to the pregnant woman's belly, the operator can extend the probe push rod 24 to allow the ultrasonic probe 57 to stick to the pregnant woman's belly for fetal heart monitoring.

[0024] It should be noted that the liquid storage box 20 is separated by a partition 27, with electrogel stored on one side and detergent stored on the other side. When the rotating rod 22 drives the liquid flow holes 31 on both sides to rotate to coincide with the corresponding opening ends of the liquid guide tube 30, the detergent and electrogel in the liquid storage box 20 will flow into the outer tube 33 through the liquid inlet hole 34 and the gel inlet hole 35 respectively, which is convenient for throwing and use.

[0025] It should be noted that when the detergent needs to be scraped off, the retracted rod 25 located on the right side of the trigger box 12 is retracted, so that the scraper 26 located on the right side of the trigger box 12 does not contact the pregnant woman's belly. On the contrary, when the gel needs to be scraped off, the scraper 26 located on the left side of the trigger box 12 also does not contact the pregnant woman's belly.

[0026] It should be noted that the cleaning agent of this solution is a soap-free cleaning product and will not leave residue on the skin of pregnant women to affect the conductive properties of the conductive gel.

[0027] It should be noted that when the outer ring 45 drives the push magnetic block 47 to move to the outside of the bottom tube 44, the push magnetic block 47 will move away from the bottom of the inner plate 41. At this time, the magnetic force between the trigger magnet and the push magnetic block 47 disappears. At this time, the inner plate 41 will return to its original position under the elastic force of the damping spring 43. The outer hole 40 and the inner hole 42 no longer overlap, and the unopened part of the inner plate 41 will block the detergent again. At this time, the infusion channel 38 will no longer throw out the detergent.

[0028] It should be noted that, although the pregnant woman's belly is close to a sphere, the ultrasonic probe 57 has a small area and only detects the fetal heart rate point on the pregnant woman's belly. The entire trigger box 12 is located on the side of the ultrasonic probe 57, so the vertically set trigger box 12 can completely cover the detection point of the ultrasonic probe 57 and perform corresponding processing.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
