DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] The defect of the fetal monitoring device in the prior art is that in special circumstances, such as an epidemic, or when pregnant women find it troublesome to go to the hospital frequently for fetal monitoring, they will choose to do fetal monitoring at home, and due to their own unskilled operation, the monitoring results will often be inaccurate;

[0043] To solve the above problems, the main concept adopted in this embodiment is: the motor drives the rotating shaft to rotate, tightens the strap through the storage disk, and at the same time drives the scraping device to evenly spread the coupling agent. When the motor stops rotating, the motor stops working, and the strap is tightened.

[0044] In order to better understand the above technical solution, Figure 1-7 And specific implementation methods are used to describe the above technical solutions in detail:

[0045] A fetal monitor provided by the present invention comprises a monitor body, a connecting line, a probe 1 and a strap 2, wherein the probe 1 is connected to the monitor body via the connecting line, a working groove 11 is provided on the side of the probe 1 that contacts the skin, the interior of the probe 1 is a cavity, a chip is provided in the cavity, and the probe 1 further comprises:

[0046] A motor 3, wherein the motor 3 is located in the cavity and is fixedly connected to the inner wall of the bottom of the probe 1;

[0047] A rotating shaft 31, the rotating shaft 31 cooperates with the motor 3, and a folding groove 311 is provided on the upper end of the surface of the rotating shaft 31;

[0048] A storage tray 32, the storage tray 32 is fixedly connected to the outer surface of the rotating shaft 31 and is located below the folding groove 311;

[0049] A tightening belt 33, one end of which cooperates with the storage tray 32, and the other end of which is fixedly connected to the binding belt 2, so as to tighten the binding belt 2;

[0050] A pressure sensor 34, wherein the pressure sensor 34 is located at the contact surface between the strap 2 and the skin, and the motor 3 is controlled by the pressure sensor 34;

[0051] The scraping device 4 cooperates with the folding groove 311 on the rotating shaft 31 to scrape the coupling agent in the working groove 11 on the surface of the probe 1 evenly.

[0052] After the pregnant woman has applied the coupling agent and put on the bandage 2, she only needs to hold the probe 1 in a suitable position with her hands, and then the motor 3 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the storage plate 32 to rotate, thereby tightening the tightening belt 33, so that the tightening belt 33 can tighten the bandage 2, and at the same time, the rotating shaft 31 drives the scraping device 4 to evenly scrape the coupling agent in the working groove 11, so as to prevent uneven coupling agent application area from causing uneven monitoring range or small coupling agent application area from causing small monitoring range, thereby improving detection accuracy;

[0053] As the strap 2 is tightened, the pressure sensor 34 is subjected to the pressure of the strap 2 and the skin. When the pressure on the pressure sensor 34 reaches a preset value, the motor 3 stops rotating to tighten the strap 2. Compared with the prior art in which the strap 2 is fixed by the buckle on the strap 2, the present invention only requires a person to hold the probe 1 in an appropriate position, and the motor 3 will automatically tighten the strap 2, thereby avoiding the situation in which the position of the probe 1 is offset when the pregnant woman is operating alone and the strap 2 is tied. It can prevent the monitoring result from being inaccurate due to the strap 2 being too loose, further improving the monitoring accuracy, and at the same time avoiding the discomfort caused to the pregnant woman when the strap 2 is too tight, causing the pregnant woman to feel nervous, and increasing the difficulty of monitoring.

[0054] An ultrasonic emitting element 7 is arranged on the inner wall of the probe 1 near the scraping device 4, so that the ultrasonic emitting element 7 can be closer to the human body and avoid the ultrasonic wave being blocked by the straps and other structures, causing the ultrasonic wave to be severely attenuated, thereby affecting the accuracy of the detection result.

[0055] As an embodiment of the present invention, the scraping device 4 includes:

[0056] An annular cylinder 41, which is sleeved on the outer surface of the rotating shaft 31 and corresponds to the position of the folding groove 311. A sliding column 42 is fixedly connected inside the annular cylinder 41, and the sliding column 42 slides in the folding groove 311;

[0057] The contact surface between the annular cylinder 41 and the probe 1 is provided with a limiting groove 411, and the corresponding position of the probe 1 is provided with a protrusion 412 which cooperates with the limiting groove 411 to limit the annular cylinder 41. As the rotating shaft 31 rotates, the annular cylinder 41 can move up and down;

[0058] A connecting column 43, wherein the connecting column 43 is fixedly connected to the upper surface of the rotating shaft 31, and a clamping groove 44 is formed on both sides of the connecting column 43;

[0059] A sleeve 45, the inner surface of which is slidably connected to the outer surface of the connecting column 43, and a clamping block 46 is provided on the inner surface of the sleeve 45, and the clamping block 46 slides in the clamping groove 44;

[0060] The lifting plate 47 is made of magnetic material, is placed on the upper end surface of the annular cylinder 41, is rotatably connected to the annular cylinder 41, and the lower surface of the lifting plate 47 is fixedly connected to the upper surface of the sleeve 45;

[0061] The scraper 48 is made of magnetic material and is located in the working groove 11. One end of the scraper 48 is slidably connected to the side wall of the working groove 11, and the other end is in contact with the side wall of the lifting plate 47 when it is raised.

[0062] When the rotating shaft 31 starts to rotate, the sliding column 42 slides along the broken line groove 311 on the rotating shaft 31. Since the connecting column 43 is fixedly connected to the annular cylinder 41, the annular cylinder 41 is driven to move linearly up and down. At the same time, since the contact surface between the annular cylinder 41 and the probe 1 is provided with a limiting groove 411, and the corresponding position of the probe 1 is provided with a protrusion 412 that cooperates with the limiting groove 412 to limit the annular cylinder 41, the annular cylinder 41 can only slide up and down, and will not rotate with the rotating shaft. Since the lifting plate 47 is placed on the upper end surface of the annular cylinder 41, the lifting plate 47 moves with the annular cylinder 41.

[0063] As the shaft 31 rotates, the sleeve 45 and the connecting column 43 rotate together with the shaft 31 because the connecting column 43 is fixedly connected to the upper surface of the shaft 31 and the block 46 in the sleeve 45 cooperates with the slot 44.

[0064] Because the lower surface of the lifting plate 47 is fixedly connected to the upper surface of the sleeve 45, the lifting plate 47 can rotate with the sleeve 45. As the annular tube 41 drives the lifting plate 47 to move up and down, the block 46 in the sleeve 45 slides up and down in the slot 44 of the connecting column 43. When the lifting plate 47 exceeds the surface of the sliding slot, the ultrasonic wave generated by the chip in the probe 1 is not affected by the magnetic force. Under the action of the magnetic force, without affecting the operation of the probe, the lifting plate 47 can drive the scraper 48 to rotate in the working slot 11, thereby evenly scraping the coupling agent in the working slot 11 to prevent uneven coupling agent coating area from causing uneven monitoring range or small coupling agent coating area from causing small monitoring range, thereby improving detection accuracy.

[0065] The motor 3 is a low-speed high-torque motor.

[0066] Since the motor 3 is a low-speed high-torque motor, the motor 3 can better tighten the strap 2 at a low speed, thereby avoiding the discomfort caused to the pregnant woman by the excessively fast tightening speed due to the excessively fast speed of the motor 3.

[0067] As an implementation mode of the present invention, the motor 3 is also controlled by a controller.

[0068] When the motor 3 stops working and the strap 2 is tightened, the pregnant woman can also control the motor 3 to rotate slightly through the controller, thereby adjusting the tightening degree of the strap 2 within a small range, further improving the monitoring accuracy and allowing the pregnant woman to adjust the strap 2 to a more comfortable state.

[0069] As an implementation mode of the present invention, the probe 1 further includes a warning light 5 , and the warning light 5 is connected to the motor 3 in an electrical circuit.

[0070] In order to prevent the motor 3 from malfunctioning and becoming uncontrolled, thereby causing risks, a warning light 5 is provided. When the motor 3 malfunctions, the warning light 5 lights up to serve as a warning.

[0071] As an embodiment of the present invention, the binding strap 2 is divided into a breathable layer 21 , an adsorption layer 22 and a dustproof layer 25 .

[0072] When the fetal monitor is used in hot weather, the pregnant woman will sweat because she is wearing the strap 2, and the skin covered by the strap 2 will be ventilated by the breathable layer 21. While having better breathability, the adsorption layer 22 can absorb sweat stains, thereby improving the comfort and use experience of the pregnant woman, while the dustproof layer can prevent dust from adhering to keep the surface of the strap 2 free of dust.

[0073] As an embodiment of the present invention, the binding strap 2 can be further divided into a heating layer 23 and a dustproof layer 25 , and a heating pad 24 is disposed in the heating layer 23 .

[0074] When using a fetal monitor in cold weather, the pregnant woman needs to expose her abdomen. To prevent the pregnant woman from getting cold and causing discomfort, please follow the instructions. Figure 7 As shown, heat is generated by the heating pad 24, and the heat is conducted to the skin through the heating layer 23, thereby keeping the waist and abdomen warm, improving the adaptability of the fetal monitor while also improving the comfort of the pregnant woman.

[0075] As an implementation mode of the present invention, the scraper 48 is in an L-shaped structure at one end close to the working groove 11 , and a sliding groove cooperating therewith is provided on the side wall of the working groove 11 .

[0076] The scraper 48 slides in the slide groove of the side wall of the working groove 11 by one end of the L-shaped structure, so that the scraper 48 can rotate in a stable state, preventing the scraper 48 from being misplaced and losing its effect.

[0077] As an embodiment of the present invention, the probe 1 is externally covered with a protective shell 6 .

[0078] In order to prevent the probe 1 from being hit and causing the chip inside the probe 1 to be damaged and affect the detection, a protective shell 6 is provided outside the probe 1 to play a protective role.

[0079] As an implementation mode of the present invention, the material of the protective shell 6 is a flexible material.

[0080] Since the protective shell 6 is made of a flexible material, such as silicone, the comfort of the pregnant woman can be further improved without affecting the operation of the probe 1. Compared with rubber, silicone is safer because it needs to contact the skin.

[0081] Working principle: After the pregnant woman applies the coupling agent and puts on the strap 2, the motor 3 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the storage plate 32 to rotate, thereby tightening the tightening belt 33, so that the tightening belt 33 can tighten the strap 2;

[0082] When the rotating shaft 31 starts to rotate, the sliding column 42 slides along the discount groove on the rotating shaft 31. Since the connecting column 43 is fixedly connected to the annular cylinder 41, the annular cylinder 41 is driven to move up and down in a straight line. Since the lifting plate 47 is placed on the upper end surface of the annular cylinder 41, the lifting plate 47 moves with the annular cylinder 41.

[0083] As the shaft 31 rotates, the sleeve 45 and the connecting column 43 rotate together with the shaft 31 because the connecting column 43 is fixedly connected to the upper surface of the shaft 31 and the block 46 in the sleeve 45 cooperates with the slot 44.

[0084] Because the lower surface of the lifting plate 47 is fixedly connected to the upper surface of the sleeve 45, the lifting plate 47 can rotate with the sleeve 45. As the annular cylinder 41 drives the lifting plate 47 to move up and down, the block 46 in the sleeve 45 slides up and down in the slot 44 of the connecting column 43. When the lifting plate 47 exceeds the surface of the sliding slot, the ultrasonic wave generated by the wafer in the probe 1 is not affected by the magnetic force. Under the action of the magnetic force, without affecting the work of the probe, the lifting plate 47 can drive the scraper 48 to rotate in the working slot 11, thereby evenly scraping the coupling agent in the working slot 11, preventing uneven coupling agent coating area from causing uneven monitoring range or small coupling agent coating area from causing small monitoring range, thereby improving detection accuracy.

[0085] As the strap 2 is tightened, the pressure sensor 34 is subjected to pressure from the strap 2 and the skin. When the pressure applied to the pressure sensor 34 reaches a preset value, the motor 3 stops rotating, thereby tightening the strap 2. Compared with the prior art in which the strap 2 is fixed by a buckle on the strap 2, the present invention automatically tightens the strap 2, thereby preventing the strap 2 from being too loose, causing inaccurate monitoring results, and further improving the monitoring accuracy.

[0086] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as the combination of these technical features does not exist, the above-mentioned embodiments only express several implementation methods of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
