Description

Technical Field

[0001] The present invention particularly relates to a fixing device for fetal heart monitoring. Background Art

[0002] In obstetric clinical practice, the probe of fetal heart monitoring equipment is generally fixed with an elastic band. When in use, the elastic band is tied under the abdomen and the probe is pressed and fixed on the abdomen. This method has the following disadvantages: 1. Slippage of the fixing belt: As the outer dimensions of the lower abdomen gradually decrease, the traditional elastic straps gradually slip during the testing process, resulting in loose fixation or slippage; 2. The probe is not firmly fixed to the elastic strap: Most existing probes rely on elastic straps to press tightly against the abdomen. During slight movements or uterine contractions of pregnant women, the probe may easily move or even fall off. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a fixing device for fetal heart monitoring, which can prevent the fixing belt and the probe from slipping during use, thereby improving the monitoring reliability.

[0004] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solution: a fixation device for fetal heart monitoring, comprising: Probe clamping fixture, used to clamp and fix the monitoring probe; There are two belts, which are symmetrically arranged on both sides of the probe clamping and fixing to form an adjustable enclosing structure; The adsorption assembly includes a plurality of adsorption units distributed in an orthogonal array along the length direction of the belt body. Each of the adsorption units includes a mounting rod and a negative pressure suction cup. Each of the negative pressure suction cups is fixed to the side of the belt body facing the human body through the mounting rod.

[0005] Furthermore, it also includes a pressurizing linkage mechanism, which is arranged on the belt body and is used to press all the negative pressure suction cups onto the skin at the same time.

[0006] Furthermore, the pressurized linkage mechanism includes a pressure plate, a pushing airbag and a first inflation device. Each of the mounting rods is provided with a pressure plate and a pushing airbag, and the pressure plate is located on the side close to the negative pressure suction cup. All the pushing airbags are in a state of mutual series connection. The first inflation device is connected to one of the pushing airbags for inflating the pushing airbag.

[0007] Furthermore, the belt body includes a plurality of flexible plates that are hinged in sequence and can be bent and deformed.

[0008] Furthermore, a first magnetic component and a second magnetic component with opposite magnetic properties are respectively embedded in the flexible plate body at the two tail ends.

[0009] Furthermore, the mounting rod is a hollow rod, and the top ends of all the mounting rods are connected to each other through air pipes, and one of the hollow rods is connected to the second inflation device.

[0010] Furthermore, the probe clamping and fixing device includes an outer frame and a clamping member, and the clamping member is used to fix the monitoring probe in the outer frame.

[0011] Furthermore, the clamping member includes a rotating drive member, a driving disk and a clamping rod, and the outer frame is provided with a plurality of sliding grooves connected to its inner cavity along its axial radial direction, and each sliding groove is provided with a clamping rod that can slide along the sliding groove, and the driving disk is coaxially arranged with the outer frame, and a plurality of arc guide grooves are provided on the driving disk at axial intervals, and the arc guide grooves correspond to the sliding grooves one by one, and a pin is provided at the top of each clamping rod, and the pin can be slidably inserted in the arc guide groove, and the rotating driving source is connected to the driving disk for driving the driving disk to rotate.

The two ends of the auxiliary belt can be overlapped and fixed to each other. One end of the connecting belt is connected to the middle of the auxiliary belt, and the other end can be hung with the outer edge of the probe clamping fixture.

[0014] Beneficial effects of the present invention: When using the above-mentioned fetal heart monitoring fixing device, the monitoring probe is first fixed to the probe clamping fixture. Then, the belt is wrapped around the abdomen while applying pressure toward the abdomen so that the suction cup of the adsorption unit is adsorbed on the abdomen. This can fix the belt on the abdomen and then fix the monitoring probe.

[0015] By adopting this fixing device, since the monitoring probe is fixed by the clamping fixing piece, relative displacement between the monitoring probe and the belt body can be prevented.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See Figures 1 to 4 The present invention provides a fixing device for fetal heart monitoring, including a probe clamping fixture 100, a belt body 200 and an adsorption component 300.

[0020] Specifically, the probe clamping fixture 100 is used to clamp and secure the monitoring probe 1. Two straps 200 are symmetrically arranged on either side of the probe clamping fixture, forming an adjustable enclosure. The suction assembly 300 comprises a plurality of suction units arranged in an orthogonal array along the length of the strap 200. Each suction unit comprises a mounting rod 310 and a negative pressure suction cup 320. Each negative pressure suction cup 320 is secured to the side of the strap 200 facing the body via the mounting rod 310.

[0021] When in use, first fix the monitoring probe 1 on the probe clamping fixture 100, then wrap the belt 200 around the abdomen while applying pressure toward the abdomen so that the suction cup of the adsorption unit is adsorbed on the abdomen, and the belt 200 can be fixed on the abdomen, thereby fixing the monitoring probe 1.

[0022] By adopting this fixing device, since the monitoring probe 1 is fixed by the clamping fixing piece, relative displacement between the monitoring probe 1 and the belt body 200 can be prevented. At the same time, since the belt body 200 is fixed by multiple negative pressure suction cups 320, the belt body 200 can be conveniently fixed. In addition, the suction cups are independent of each other. During the fixing process, the suction cups act alone, which can prevent the entire belt body 200 from moving due to other situations such as uterine contractions during use, thereby greatly improving the stability of the fixation and further improving the accuracy of the monitoring data.

[0023] As an effective implementation, the device further includes a pressurizing linkage mechanism 400 , which is provided on the belt body 200 and is used to simultaneously press all the negative pressure suction cups 320 against the skin.

[0024] Specifically, the pressurizing linkage mechanism 400 includes a pressure plate 410, a pushing airbag 420 and a first inflation device. Each mounting rod 310 is provided with a pressure plate 410 and a pushing airbag 420, and the pressure plate 410 is located on the side close to the negative pressure suction cup 320. All the pushing airbags 420 are in a state of mutual series connection. The first inflation device is connected to one of the pushing airbags 420 for inflating the pushing airbag 420.

[0025] During use, when the negative pressure suction cup 320 is adsorbed on the abdomen, the first inflation device is activated to push the airbag 420 to expand while pushing the pressure plate 410 to press the negative pressure suction cup 320 against the abdomen, further improving the negative pressure adsorption effect.

[0026] In this embodiment, the belt 200 includes a plurality of sequentially hinged, bendable, and deformable flexible plates 210. The flexible plates 210 allow the curved shape of the abdomen to be utilized. Furthermore, the flexible plates 210 provide a reverse thrust to the push airbags 420, thereby increasing the pressing force of the push airbags 420 on the negative pressure cups 320.

[0027] In this embodiment, the tail ends of the two belt bodies 200 may be connected or not connected.

[0028] When the tail ends are connected, the flexible plates 210 at the two ends can be embedded with first and second magnetic members of opposite magnetic properties. When the ends need to be connected, the two flexible plates 210 at the tail ends are overlapped. The mutual attraction between the first and second magnetic members can quickly complete the connection of the tail ends of the belt body 200, further improving the fixing effect.

[0029] As another preferred embodiment, in a specific implementation, the mounting rods 310 are hollow rods, the top ends of all the mounting rods 310 are interconnected through air tubes, and one of the hollow rods is connected to the second inflation device.

[0030] When it is necessary to separate the negative pressure suction cup 320 from the abdomen, the second inflator can be used to inflate the mounting rod 310, thereby releasing the negative pressure between the negative pressure suction cup 320 and the abdomen, and thus smoothly separating the suction assembly 300 from the abdomen. In practice, the first and second inflator devices can be integrated into the same device, with switching valves controlling the inflation of the push airbag 420 or the mounting rod 310, respectively.

[0031] In this embodiment, the probe clamping and fixing device includes an outer frame 110 and a clamping member 120 . The clamping member 120 is used to fix the monitoring probe 1 in the outer frame 110 .

[0032] Specifically, the clamping member 120 includes a rotating driving member 121, a driving disk 122 and a clamping rod 123. The outer frame 110 is provided with a plurality of sliding grooves connected to its inner cavity along its axial radial direction. A clamping rod 123 that can slide along the sliding groove is provided in each sliding groove. The driving disk 122 is coaxially arranged with the outer frame 110. A plurality of arc guide grooves are provided axially at intervals on the driving disk 122, and the arc guide grooves correspond one-to-one to the sliding grooves. A pin is provided at the top of each clamping rod 123, which can be slidably inserted in the arc guide groove. The rotating driving source is connected to the driving disk 122 for driving the driving disk 122 to rotate.

[0033] Among them, the rotating driving component 121 includes a handle 1211 and a locking screw 1212. The handle 1211 is set on the driving disk 122. The driving disk 122 can be manually rotated through the handle 1211. The locking screw 1212 is connected to the driving disk 122. By rotating the locking screw 1212, the end of the locking screw 1212 can be tightened against the end of the outer frame 110.

[0034] In use, firstly, the locking screw 1212 is loosened, then the driving disc 122 is rotated clockwise through the handle 1211, under the action of the sliding groove and the arc-shaped guide groove, all the clamping rods 123 are driven to move towards the hollow direction until the monitoring probe 1 is clamped and fixed, then the locking screw 1212 is locked.

[0035] In this way, the monitoring probe 1 can be clamped and fixed at multiple points, thereby improving the installation stability.

[0036] As another more preferred embodiment, the device further comprises an auxiliary fixing belt 500, the auxiliary fixing belt 500 comprises an auxiliary belt 510 and a connecting belt 520, the auxiliary belt 510 is an elastic belt, the two ends of the auxiliary belt 510 can be mutually overlapped and fixed, one end of the connecting belt 520 is connected to the middle part of the auxiliary belt 510, and the other end can be hung with the outer edge of the probe clamping and fixing piece 100.

[0037] After the related components such as the probe and the belt body 200 are fixed, the auxiliary belt 510 can be wrapped around the chest part, then the connecting belt 520 is connected with the probe clamping and fixing piece 100, and the connection mode can be hanging, inserting or bonding, thereby further improving the stability of the monitoring probe 1.

[0038] The above-mentioned fixing device for fetal heart monitoring: since the monitoring probe 1 is fixed through the clamping and fixing piece, the relative displacement phenomenon between the monitoring probe 1 and the belt body 200 can be prevented, meanwhile, since the belt body 200 is fixed through the multiple negative pressure suction cups 320, the fixing of the belt body 200 can be conveniently performed, in addition, the suction cups are mutually independent, and the suction cups act independently during the fixing process, thereby preventing the movement of the entire belt body 200 due to uterine contraction and other conditions during use, thereby greatly improving the stability of the fixing and further improving the accuracy of the monitoring data.

[0039] In addition, the hollow setting of the mounting rod 310 can conveniently separate the negative pressure suction cup 320 from the skin; the auxiliary fixing of the auxiliary fixing belt 500 can further improve the overall fixing effect.

[0040] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same; although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application.
