The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0025] See also Figure 1 An embodiment of the present application provides a fetal monitoring device, which includes a body and a fetal monitoring probe 1.

[0026] The fetal monitoring probe 1 can be connected to the body. The fetal monitoring probe 1 and the body can be connected by wire or wirelessly, so that the data detected by the fetal monitoring probe 1 can be transmitted to the body.

[0027] For example, the main body may be provided with a display screen so that the user can observe the data transmitted from the fetal monitoring probe 1 through the display screen.

[0028] In some embodiments, the fetal monitoring probe 1 includes a housing assembly 10 and electrical components. The electrical components can be installed in the housing assembly 10, and the housing assembly 10 can protect the electrical components.

[0029] See also Figure 1 to Figure 2 In some embodiments, the housing assembly 10 includes an upper housing 11 and a lower housing 13 , which are connected to form a device accommodating space 15 , and electrical components can be disposed in the device accommodating space 15 .

[0030] It should be noted that, in the upper shell 10 and the lower shell 11 , “upper” and “lower” are only used to distinguish the spatial positions of the shells, and cannot be understood as limitations on the shapes, structures, etc. of the upper shell 10 and the lower shell 11 .

[0031] In some embodiments, the upper shell 11 and the lower shell 13 may be sealed to improve the waterproof performance of the shell assembly 10 .

[0032] Please refer to 3 to Figure 4 In some embodiments, the upper shell 11 can be bonded to the lower shell 13 to seal the device accommodating space 15. The bonding and sealing method is relatively simple and easy to operate.

[0033] Specifically, one of the upper shell 11 and the lower shell 13 can be provided with a second annular groove 141, and the other can be provided with a second annular protrusion 113 that cooperates with the second annular groove 141. The second annular protrusion 113 is inserted into the second annular groove 141. The first bonding portion can bond the groove wall of the second annular groove 141 and the second annular protrusion 113, and seal the device accommodating space 15. In this way, arranging the first bonding portion in the groove helps to improve the overflow of glue, thereby reducing the subsequent process of handling the overflow of glue, and also facilitates gluing, reducing the difficulty of assembly.

[0034] That is, the upper shell 11 may be provided with a second annular groove 141, and the lower shell 13 may be provided with a second annular protrusion 113 that matches the second annular groove 141. Alternatively, the lower shell 13 may be provided with a second annular groove, and the upper shell 11 may be provided with a second annular protrusion that matches the second annular groove.

[0035] The first bonding part may be made of glue or a waterproof bonding member thereof.

[0036] In some embodiments, the housing assembly 10 may further include a connector 23 and a top bead 25, and the top bead 25 may be connected to the upper housing 11 through the connector 23. The top bead 25 may be used to fix a strap to facilitate fixing the fetal monitoring probe 1 to the abdomen of a pregnant woman.

[0037] Specifically, the connecting member 23 may be inserted into the upper shell 11 , the connecting member 23 is at least partially exposed from the upper shell 11 , and the top particle 25 is connected to a side of the connecting member 23 exposed from the upper shell 11 .

[0038] The connecting member 23 may be a screw, a threaded rod, a rivet or other fixing members, so that the connecting member 23 and the top particle 25 may be connected by a thread, which is not only convenient for assembly but also for disassembly and replacement of the top particle 25 .

[0039] In some embodiments, a sealed connection may be adopted between the connector 23 and the upper housing 11 to improve the waterproof performance of the housing assembly 10 .

[0040] In some embodiments, the shell assembly 10 may further include a second bonding portion, and the connecting member 23 and the upper shell 11 may be sealed and bonded via the second bonding portion. In this way, the connecting member 23 and the upper shell 11 are bonded and sealed via the second bonding portion, and the bonding and sealing method is relatively simple and easy to operate.

[0041] The second bonding part may be made of glue or a waterproof bonding member thereof.

[0042] See also Figure 2In some embodiments, the second bonding portion can bond the connector 23 and the upper shell 11 in a variety of ways. The upper shell 11 is provided with a through hole 111 or a threaded hole. The connector 23 uses a screw as an example. The screw can be inserted into the through hole 111, and the head of the screw can be located in the device accommodating space 15.

[0043] As an example, the second bonding portion may be located between the screw and the hole wall of the through hole 111 , so that the connecting member 23 and the upper shell 11 may be sealed and bonded via the second bonding portion.

[0044] As another example, the second bonding portion may be bonded between the head of the screw and the upper shell 11 , so that the connecting member 23 and the upper shell 11 may be sealed and bonded via the second bonding portion.

[0045] As another example, the second bonding portion covers the head of the screw and is bonded to the upper shell 11, so that the connecting piece 23 and the upper shell 11 can be sealed and bonded by the second bonding portion. This helps to avoid the second bonding portion overflowing outside the upper shell 11 and reduces the subsequent process of handling the overflowed glue.

[0046] See also Figures 4 to 5 In some embodiments, the shell assembly 10 further includes a waterproof breathable membrane 19, the lower shell 13 is provided with a fixing installation hole 131, the fixing installation hole 131 connects the device accommodating space 15 with the external environment space, and the waterproof breathable membrane 19 is arranged in the fixing installation hole 131, so that the gas in the device accommodating space 15 can flow to the external environment space through the waterproof breathable membrane 19 in the fixing installation hole 131, while the liquid in the external environment space is blocked by the waterproof breathable membrane 19 and is difficult to enter the device accommodating space 15, thereby improving the waterproof performance of the shell assembly 10.

[0047] In addition, since the present application sets the waterproof breathable membrane 19 in the fixing installation hole 131, the fixing installation hole 131 has waterproof and breathable properties, so there is no need to seal the fixing 17 and the lower shell 13 with glue, which improves production efficiency and does not need to consider the problem of glue overflow. Moreover, when the shell assembly 10 is used in the fetal monitoring probe 1 and the fetal monitoring device, the top grain 25 does not need to be provided with a vent hole, which helps to avoid the influence of the vent hole on the shape design and manufacturing process of the top grain 25, expands the shape design of the top grain 25, and reduces the production difficulty and production cost of the top grain 25.

[0048] The waterproof breathable membrane 19 may be a breathable membrane with high molecular microporous filtration, such as polytetrafluoroethylene (PTFE) resin, or the waterproof breathable membrane 19 may be made of other materials with waterproof and breathable properties, which is not limited in the present application.

[0049] The fixing member installation hole 131 can be used to install the fixing member 17, and the fixing member 17 can be inserted into the fixing member installation hole 131 and the upper shell 11 to connect and fix the upper shell 11 and the lower shell 13. The fixing member 17 can be a screw, a threaded rod, a rivet or other fixing members.

[0050] The number of the fixing member installation holes 131 may be one or more, which is not limited in the present application. When the number of the fixing member installation holes 131 is more than one, a waterproof breathable membrane 19 may be disposed in each fixing member installation hole 131, or a waterproof breathable membrane 19 may be disposed in a plurality of the fixing member installation holes 131.

[0051] It can be understood that one implementation of the fixing installation hole 131 connecting the device accommodating space 15 with the external environment space may be that the gas in the device accommodating space 15 can enter the fixing installation hole 131 through the gap between the fixing 17 and the lower shell 13, and then flow to the external environment space through the waterproof breathable membrane 19.

[0052] Another implementation manner in which the fixing member installation hole 131 connects the device accommodating space 15 with the external environment space may be to provide a through hole on the hole wall of the fixing member installation hole 131 to connect the device accommodating space 15 with the external environment space.

[0053] Alternatively, the fixing member installation hole 131 may connect the device accommodating space 15 with the external environment space in other embodiments.

[0054] In some embodiments, the waterproof breathable membrane 19 can separate the fixing component mounting hole 131 into a first mounting hole 1311 and a second mounting hole 1313, and the first mounting hole 1311 and the second mounting hole 1313 are distributed from the lower shell 13 to the upper shell 11; the second mounting hole 1313 is used to install the fixing component 17, and the first mounting hole 1311 is connected to the external environment space, so that the waterproof breathable membrane 19 can be located inside the fixing component mounting hole 131, which helps to reduce damage to the waterproof breathable membrane 19 due to exposure and prolongs the service life of the waterproof breathable membrane 19.

[0055] The direction from the lower shell 13 to the upper shell 11 may be the axial direction of the fixing member installation hole 131 .

[0056] In some embodiments, the waterproof breathable membrane 19 can be disposed in the fixing member installation hole 131 in a variety of ways.

[0057] As an example, the waterproof breathable membrane 19 and the hole wall of the fixing member mounting hole 131 can be interference connected, so as to improve the situation where the waterproof breathable membrane 19 falls off, and also help to improve the situation where external liquid flows into the device accommodating space 15 through the gap between the waterproof breathable membrane 19 and the hole wall of the fixing member mounting hole 131.

[0058] As another example, the waterproof breathable membrane 19 can be bonded to the hole wall of the fixing component mounting hole 131, so that the connection between the waterproof breathable membrane 19 and the hole wall of the fixing component mounting hole 131 is more firmly connected, further improving the situation where the waterproof breathable membrane 19 falls off and liquid enters the device accommodating space 15.

[0059] As another example, the waterproof breathable membrane 19 can be interference-connected and bonded to the hole wall of the fixing component mounting hole 131, so that the connection between the waterproof breathable membrane 19 and the hole wall of the fixing component mounting hole 131 is more secure, further improving the situation where the waterproof breathable membrane 19 falls off and liquid enters the device accommodating space 15.

[0060] In some embodiments, the lower shell 13 may include a mounting post 135, which may protrude from the device accommodating space 15, and the fixing member mounting hole 131 may pass through the mounting post 135, thereby extending the axial length of the fixing member mounting hole 131 without increasing the overall thickness of the lower shell 13, thereby increasing the volume of the device accommodating space 15.

[0061] In some embodiments, another embodiment in which the fixing member mounting hole 131 connects the device accommodating space 15 with the external environment space may be that the side wall of the mounting column 135 may be provided with a vent hole 1351, and the vent hole 1351 may connect the second mounting hole 1313 and the device accommodating space 15, so that the gas in the device accommodating space 15 can flow more smoothly through the vent hole 1351 to the external environment space, thereby improving the air permeability of the shell assembly 10.

[0062] The vent hole 1351 can be arranged at a position spaced apart from the fixing member 17 in the fixing member installation hole 131, which helps to avoid the situation where the fixing member 17 blocks the vent hole 1351, so that the gas flows more smoothly. Alternatively, the vent hole 1351 can be at least partially arranged at a position between the fixing member 17 and the waterproof breathable membrane 19, so that the gas flows more smoothly.

[0063] It can be understood that in this embodiment, the gas in the device accommodating space 15 can enter the second mounting hole 1313 through the vent hole 1351, and then flow to the external environment space after passing through the waterproof breathable membrane 19 and the second mounting hole 1313.

[0064] See also Figure 2 and Figure 4In some embodiments, the housing assembly 10 may further include a plug 21, which may be installed in the first mounting hole 1311. The plug 21 may be provided with a vent hole 211, which may connect the first mounting hole 1311 and the external environment space, so that the plug 21 may shield the waterproof breathable membrane 19, which helps to reduce damage to the waterproof breathable membrane 19 and prolong the service life of the waterproof breathable membrane 19. It can be understood that in this embodiment, after passing through the waterproof breathable membrane 19, the gas in the device accommodating space 15 may enter the external environment space through the first mounting hole 1311, the vent hole 211 in sequence.

[0065] In addition, since the plug 21 is installed in the first mounting hole 1311 and the air permeable hole 211 is provided in the plug 21, the diameter of the air permeable hole 211 is smaller than the diameter of the first mounting hole 1311, so that the liquid in the external environment space needs to pass through the air permeable hole 211 before contacting the waterproof breathable membrane 19, thereby reducing the amount of water entering, reducing the pressure generated by the liquid on the waterproof breathable membrane 19, and extending the service life of the waterproof breathable membrane 19.

[0066] The plug 21 may be made of a flexible material, so as to facilitate installation of the plug 21 in the first installation hole 1311. For example, the plug 21 may be made of silicone, rubber or other flexible materials.

[0067] It can be understood that in this embodiment, the gas in the device accommodating space 15 passes through the waterproof breathable membrane 19 and then flows to the external environment space through the breathable through hole 211 .

[0068] In some embodiments, a first annular protrusion 213 may be provided around the outer peripheral surface of the plug 21, and the first annular protrusion 213 may abut against the hole wall of the first mounting hole 1311, so that the plug 21 and the hole wall of the first mounting hole 1311 are interference connected, which helps to reduce the possibility of the plug 21 falling off.

[0069] In some embodiments, the hole wall of the first mounting hole 1311 may be provided with a first annular groove 137, and the first annular protrusion 213 may be clamped in the first annular groove 137, so that the plug 21 can be more stably placed in the first mounting hole 1311, which also helps to reduce the possibility of the plug 21 falling off.

[0070] In some embodiments, the lower housing 13 may have a mounting surface 139, which may be located in the fixing hole 131, and the waterproof breathable membrane 19 may be attached to the mounting surface 139, so that the waterproof breathable membrane 19 is easier to install and the assembly difficulty is reduced. For example, the waterproof breathable membrane 19 may adopt a single-sided adhesive structure to be attached to the mounting surface 139.

[0071] Specifically, the fixing member installation hole 131 may be a stepped hole, and a mounting surface 139 is formed in the fixing member installation hole 131 .

[0072] See also Figures 4 to 5 In some embodiments, the waterproof breathable membrane 19 can be adhered between the mounting surface 139 and the plug 21, thereby further improving the situation where the waterproof breathable membrane 19 falls off. In addition, the bonding force between the waterproof breathable membrane 19 and the plug 21 also helps to improve the situation where the plug 21 falls off. For example, the waterproof breathable membrane 19 can adopt a double-sided adhesive structure to be adhered between the mounting surface 139 and the plug 21.

[0073] In the shell assembly 10, fetal monitoring probe 1 and fetal monitoring equipment provided by the present application, the upper shell 11 and the lower shell 13 are connected to form a device accommodating space 15, the lower shell 13 is provided with a fixing installation hole 131, the fixing installation hole 131 connects the device accommodating space 15 with the external environment space, and the waterproof breathable membrane 19 is arranged in the fixing installation hole 131. In this way, the fixing installation hole 131 has waterproof and breathable properties under the action of the waterproof breathable membrane 19, so that there is no need to seal the fixing 17 in the fixing installation hole 131 and the lower shell 13 with glue, which improves production efficiency and does not need to consider the problem of glue overflow. In addition, when the shell assembly 10 is applied to the fetal monitoring probe 1 and the fetal monitoring equipment, the top grain 25 does not need to be provided with a vent hole, which helps to avoid the influence of the vent hole on the shape design and manufacturing process of the top grain 25, expands the shape design of the top grain 25, and reduces the production difficulty and production cost of the top grain 25.
