[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] To this end, an embodiment of the present invention provides a storable fetal heart monitoring device, the purpose of which is at least to, when fetal heart monitoring is needed, directly apply the coupling agent to the surface of the fetal heart probe 4 inserted into the first fixing component 2 through the application component 6, so that the coupling agent can be easily and evenly applied to the fetal heart probe 4, and bubbles can be avoided between the fetal heart probe 4 and the skin, so that fetal heart monitoring data can be obtained more accurately.

[0021] Embodiment: A storable fetal heart rate monitoring device, such as Figure 1 - Figure 6 As shown, it comprises a fixing belt 1, comprising a first belt 11 and a second belt 12, and an elastic inner belt 13 is arranged on the inner side of the first belt 11 and the second belt 12; The first fixing assembly 2 and the second fixing assembly 3 are respectively used to connect the two ends of the first strap 11 and the second strap 12. The first fixing assembly 2 and the second fixing assembly 3 are both provided with mounting holes for fixing the fetal heart probe 4 and the uterine contraction probe 5. The first limiting sleeve 22 and the second limiting sleeve 31 are respectively coaxially fixedly installed inside the two mounting holes. The first limiting sleeve 22 and the second limiting sleeve 31 are respectively used to clamp the fetal heart probe 4 and the uterine contraction probe 5 (both the fetal heart probe 4 and the uterine contraction probe 5 are designed with protrusions for clamping inside the mounting holes, which are common structures in the prior art, such as Figure 2 As shown, the first fixing assembly 2 includes a housing 21; The smear component 6 is slidably installed inside the shell 21 (a guide rail is provided inside the shell 21 to guide the sliding of the smear component 6, which is a common sliding structure in the prior art, not shown in the figure, so it is not repeated), the smear component 6 includes a mounting frame 63, a smear plate 69 is rotatably installed in the middle of the mounting frame 63, a meshing gear 691 is fixedly installed on the back of the smear plate 69, and a driving motor 68 for driving the meshing gear 691 to rotate is fixedly installed on the mounting frame 63.

[0022] In the present invention, by setting the smear component 6 inside the first fixing component 2, before fetal heart monitoring, the smear component 6 is first moved to one side of the mounting hole of the first fixing component 2, and then the fetal heart probe 4 is inserted into the mounting hole of the first fixing component 2, so that the fetal heart probe 4 and the end surface that is about to be in contact with the skin are aligned with the smear plate 69, and then the driving motor 68 drives the meshing gear 691 to rotate, thereby driving the smear plate 69 to rotate on the mounting frame 63. During the rotation of the smear plate 69, the coupling agent attached to the surface of the smear plate 69 can be evenly smeared on the fetal heart probe 4 (in one embodiment, the coupling agent can be squeezed out and attached to the smear plate 69 in advance).

[0023] It should be noted that after the coupling agent is applied, the fetal heart probe 4 is first pulled out, and then the application component 6 is slid toward the side of the mounting hole so that the application component 6 is located on the side of the mounting hole. Then, the fetal heart probe 4 is inserted into the mounting hole of the first fixing component 2 again and the detection surface of the fetal heart probe 4 is in contact with the pregnant woman's skin. A data transmission wire is provided at the tail of the fetal heart probe 4, and the other end of the wire is connected to a data host (a mobile phone or other display storage body), and the host stores the detection data.

[0024] In addition, during use, the fixing belt 1 is first used to wrap around the waist of the pregnant woman so that the first fixing component 2 and the second fixing component 3 are firmly fixed on the waist of the pregnant woman. During this process, there is no need to hold the fetal heart probe 4 or the uterine contraction probe 5 (compared to the prior art), which can be more convenient to operate.

[0025] Furthermore, if Figure 6 and Figure 8 As shown, a mounting through hole 6901 is provided in the middle of the smear plate 69, and a plurality of supply grooves 6902 are provided in a circular distribution around the mounting through hole 6901. The plurality of supply grooves 6902 are all connected to the mounting through hole 6901, and a sealing plate 692 is provided at the openings of the mounting through hole 6901 and the supply grooves 6902, and a plurality of smear through holes 6903 are arranged on the sealing plate 692.

[0026] Furthermore, if Figure 6 , Figure 7 and Figure 8 As shown, a feeding assembly is provided at one end of the mounting through hole 6901 away from the feeding groove 6902 , and the feeding assembly is used to transport the coupling agent into the mounting through hole 6901 .

[0027] Among them, by setting the installation through hole 6901 and the supply groove 6902 on the smear plate 69, during use, the supply component can directly transport the coupling agent to the inside of the installation through hole 6901, and then the liquid coupling agent flows along the installation through hole 6901 and the supply groove 6902, and is squeezed out from different smearing through holes 6903 respectively. The coupling agent squeezed out from the smearing through holes 6903 is smeared to various positions of the fetal heart probe 4 as the smear plate 69 rotates, so that the coupling agent is more evenly distributed on the surface of the fetal heart probe 4.

[0028] Furthermore, if Figure 6 and Figure 7 As shown, the feeding assembly includes a liquid storage box 64 fixedly installed inside the mounting frame 63 for storing coupling agent, a connecting pipe 65 is installed below the liquid storage box 64, a rotating tube 66 is rotatably installed on the other end of the connecting rod 65, and the other end of the rotating tube 66 is fixedly docked with the mounting through hole 6901.

[0029] During use, the liquid storage box 64 is always kept above the connecting pipe 65 , so that the liquid inside the liquid storage box 64 always has a tendency to flow toward the connecting pipe 65 .

[0030] Furthermore, if Figure 6 and Figure 7 As shown, the middle portion of the rotating tube 66 is an elastic pipe, and the outer circumferential surface of the rotating tube 66 is circumferentially distributed with a plurality of semi-elliptical protrusions 661, and a support frame 67 is fixedly mounted on the mounting frame 63, and the upper end of the support frame 67 extends to the bottom of the rotating tube 66. When the rotating tube 66 rotates following the smear plate 69, the top of the support frame 67 squeezes the protrusions 661 to cause the elastic rotating tube 66 to produce intermittent deformation.

[0031] Among them, by setting the rotating tube 66 as an elastic pipe, when the rotating tube 66 rotates, the multiple protrusions 661 on the surface of the rotating tube 66 contact the top of the support frame 67 in turn, squeezing the coupling agent storage space inside the rotating tube 66. Since the end of the rotating tube 66 connected to the liquid storage tank 64 is located at the upper end and has a certain weight, when the rotating tube 66 is squeezed, the coupling agent will flow along the rotating tube 66 to the inside of the mounting through hole 6901 on the smear plate 69, and then be evenly smeared onto the fetal heart probe 4 from the smearing through hole 6903.

[0032] It should be noted that, since the coupling agent is viscous, it will not flow when no squeezing occurs (at the small hole (apply through hole 6903), the liquid (coupling agent) needs to overcome greater resistance to flow out, because the cross-sectional area of ​​the small hole is small, resulting in an increase in flow rate, which in turn generates greater shear force).

[0033] Furthermore, if Figure 5 and Figure 6 As shown, a push rod 61 is fixedly installed on the top of the liquid storage box 64, and the upper end of the push rod 61 extends out of the shell 21. The shell 21 is provided with a sliding through hole for the push rod 61 to move horizontally. A one-way valve 62 is also provided above the liquid storage box 64.

[0034] Among them, by setting a one-way valve 62 on the top of the liquid storage box 64, only air is allowed to enter the interior of the liquid storage box 64 in one direction, which can avoid the generation of negative pressure inside the liquid storage box 64 and avoid hindering the normal flow of the coupling agent; during use, the position of the push rod 61 can be adjusted to adjust the position of the entire application component 6, so that the application component 6 will not affect the insertion of the fetal heart probe 4 into the first fixing component 2 when not in use.

[0035] Furthermore, if Figure 3 and Figure 5 As shown, it also includes a sealing plate 23, which is fixedly installed inside the shell 21. The sealing plate 23 is located on one side of the first limiting sleeve 22, and the sealing plate 23 is used to seal the opening of the smear plate 69.

[0036] Among them, by arranging a sealing plate 23 inside the outer shell 21, when the smear plate 69 is pushed to the side of the first limiting sleeve 22, the sealing plate 23 can be sealed at the opening of the smear plate 69, thereby preventing the evaporation of water in the coupling agent remaining in the smear plate 69, and allowing the coupling agent to remain moist during the next use.

[0037] Furthermore, if Figure 4As shown, a guide sleeve 32 is fixedly installed inside the second fixing component 3, and the guide sleeve 32 is coaxially arranged with the second limiting sleeve 31. One end of the first fixing component 2 and the second fixing component 3 are fixedly installed with a length adjustment component, and the two groups of the length adjustment components are respectively used to adjust the connection position between the first strap 11 and the first fixing component 2 and the connection position between the second strap 12 and the second fixing component 3.

[0038] Furthermore, if Figure 4 As shown, the length adjustment assembly includes two spaced-apart limit rods 33 rotatably installed, a gap is left between the two limit rods 33 for the first strap 11 or the second strap 12 to pass through, the outer circumferential surface of the limit rod 33 is circumferentially provided with a plurality of limit protrusions 331, the upper and lower ends of the two limit rods 33 are provided with transmission gears, the transmission gears are used to drive the two limit rods 33 to rotate synchronously, and a knob 34 for driving the transmission gear to rotate is provided below the transmission gear.

[0039] Among them, by setting two limit rods 33 at intervals, when it is necessary to adjust the extension length of the first strap 11 or the second strap 12, one of the limit rods 33 can be rotated forward or reversely as needed (by turning the knob 34) to move the first strap 11 or the second strap 12 between the two limit rods 33.

[0040] Furthermore, if Figure 1 and Figure 2 As shown, the first strap 11 and the second strap 12 are formed by integral cutting, the width of the first strap 11 is not less than the width of the second strap 12, and the elastic force of the second strap 12 is smaller than that of the first strap 11, so that it can be pulled upwards and connected end to end more easily.

[0041] During use, the fixing belt 1 is first placed at the lower abdomen, and the two ends of the first strap 11 are tightened, and then the second strap 12 is pulled to the upper abdomen, and the second fixing component 3 is located at the upper abdomen of the pregnant woman.

[0042] Working principle: By rotating and installing the smear plate 69 inside the first fixing component 2, the coupling agent can be easily and evenly applied to the fetal heart probe 4. At the same time, the rotation of the smear plate 69 can also drive the rotating tube 66 to rotate, so that the coupling agent is squeezed onto the surface of the smear plate 69 as the smear plate 69 rotates, and the extrusion and coating operation is performed synchronously.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
