Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and in particular to an anti-displacement fetal heart rate monitoring belt and its usage method. Background Technology

[0002] Fetal heart rate monitoring is a routine procedure in obstetrics used to continuously collect fetal heart rate and uterine contraction pressure signals. During the procedure, a fetal heart rate monitoring belt, a medical auxiliary device, is used to stably fix the fetal heart rate monitoring probe and uterine contraction probe to the pregnant woman's abdomen to ensure continuous and stable signal acquisition. The stability, anti-displacement performance, adjustable positioning flexibility, and ease of operation of the fetal heart rate monitoring belt determine the efficiency of the monitoring procedure and the effectiveness of signal acquisition.

[0003] Currently, the fetal heart rate monitoring belts and related existing technologies widely used in clinical practice have the following main defects: First, the overall anti-displacement performance is insufficient, and the belt is prone to overall slippage; second, the adjustment flexibility of the monitoring point is insufficient, and it is impossible to achieve accurate fitting of the entire abdominal surface; third, the reliability of the probe fixation is insufficient, and relative displacement and deflection are prone to occur; fourth, it is difficult to balance the reliability of the binding and fixing structure with the wearing comfort. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-displacement fetal heart rate monitoring belt and its method of use. Two anti-slip bottom bands, respectively fixed to the upper and lower abdomen of the pregnant woman, form a frame-like fixing structure with upper and lower limits, improving the overall anti-slip performance of the belt and effectively limiting its vertical sliding and lateral displacement. Through the sliding cooperation of the guide band and the first displacement component, the first elastic band can achieve a wide range of lateral position adjustment. Through the sliding cooperation of the second displacement component and the first elastic band, the fixing mechanism and the clamped probe can achieve a wide range of longitudinal position adjustment. Together, they form an XY-axis two-dimensional adjustment system, enabling precise adjustment of any monitoring point on the entire abdomen of the pregnant woman without repeatedly adjusting the overall fixing position of the belt, thus improving the efficiency of finding and adjusting monitoring points. A synchronously linked clamping structure is adopted. By simultaneously pressing the pressing plates of the first and second buttons, the two clamps open towards each other. After releasing the buttons, the first and second springs return to their original positions, causing the two clamps to clamp the probe synchronously. The operation is simple and improves clinical efficiency.

[0005] To achieve the above objectives, the present invention provides an anti-displacement fetal heart rate monitoring belt, including an anti-slip bottom belt, a guide belt on the top surface of the anti-slip bottom belt, a first displacement member on the guide belt, a first elastic belt between two first displacement members, a second displacement member on the first elastic belt, a fixing mechanism on the second displacement member, and a binding mechanism at both ends of the anti-slip bottom belt.

[0006] Preferably, the fixing mechanism includes a fixing frame disposed on the bottom surface of the second shifting member. A first moving plate and a second moving plate are disposed inside the fixing frame. A fixing clamp is disposed on the side of the first moving plate and the second moving plate that are close to each other. A first crossbar is disposed on the side wall of the first moving plate. The other end of the first crossbar passes through the second moving plate and is connected to a first button. The other end of the first button passes through the fixing frame. A second crossbar is disposed on the side wall of the second moving plate. The other end of the second crossbar passes through the first moving plate and is connected to a second button. The other end of the second button passes through the fixing frame.

[0007] Preferably, a first spring is provided at the end of the first crossbar away from the first movable plate, one end of the first spring is in contact with the side wall of the first button, and the other end of the first spring is in contact with the side wall of the second movable plate. A second spring is provided at the end of the second crossbar away from the second movable plate, one end of the second spring is in contact with the side wall of the second button, and the other end of the second spring is in contact with the side wall of the first movable plate.

[0008] Preferably, both the first button and the second button have a pressing plate at the end away from the fixed frame.

[0009] Preferably, the fastening mechanism includes a second elastic band and a positioning buckle. The second elastic band is disposed at one end of the anti-slip bottom band, and a connecting pad is connected to the other end of the anti-slip bottom band. The positioning buckle is disposed on the connecting pad, and a positioning hole is provided at the other end of the second elastic band, through which the positioning buckle passes.

[0010] Preferably, the side wall of the first shifting member is provided with a connecting rod, and the two ends of the first elastic band are respectively disposed on the two connecting rods.

[0011] Preferably, the bottom surface of the anti-slip bottom strip is provided with a silicone strip to increase the friction of the anti-slip bottom strip.

[0012] A method for using an anti-displacement fetal heart rate monitoring belt includes the following steps: S1: Attach the two anti-slip bottom bands to the upper and lower abdomen of the pregnant woman respectively, so that the silicone strips on the bottom of the two anti-slip bottom bands are in full contact with the abdominal skin to form anti-slip limits. After wrapping the second elastic band at one end of the anti-slip bottom band around the pregnant woman's waist and abdomen, put the positioning hole at the end of the second elastic band onto the positioning buckle of the connecting pad at the other end of the anti-slip bottom band. Complete the binding of the two anti-slip bottom bands at the upper and lower abdomen in sequence. S2: Press the pressing plates at the ends of the first and second buttons in the synchronous pressing and fixing mechanism. The first and second crossbars drive the first and second moving plates to move towards each other, and simultaneously compress the first and second springs. This causes the fixing clamps on the first and second moving plates to open towards each other, so that the detection surface of the fetal heart monitoring probe faces the abdomen and fits against it. The fixing head of the fetal heart monitoring probe is placed in the clamping area between the two fixing clamps. Release the first and second buttons, and the first and second springs return to their original positions, causing the first and second moving plates to move away from each other, so that the two fixing clamps clamp and limit the fixing head of the fetal heart monitoring probe. S3: Simultaneously fine-tune the lateral arrangement of the two sets of first shifting components along the guide belt on the top surface of the anti-slip bottom belt, drive the first elastic belt to move laterally, and then fine-tune the longitudinal arrangement of the second shifting component along the first elastic belt. Through the second shifting component, drive the fixing mechanism and the clamped and fixed monitoring probe to move synchronously until the probe detection surface is aligned with and closely fits the target monitoring point on the abdomen, and start fetal heart monitoring. S4: After the fetal heart rate monitoring operation is completed, press the first button and the second button simultaneously to open the two fixing clips facing each other, remove the fetal heart rate monitoring probe, and then release the positioning holes of the second elastic band of the two anti-slip bottom bands from the corresponding positioning buckles in turn, unwrap the monitoring belt around the pregnant woman, organize the monitoring belt and put it away.

[0013] Therefore, this invention employs the aforementioned anti-displacement fetal heart rate monitoring belt and its usage method. By fixing two anti-slip bottom bands to the upper and lower abdomen of the pregnant woman, a frame-like fixing structure with upper and lower limits is formed, improving the overall anti-slip performance of the belt and effectively limiting its vertical sliding and lateral displacement. Through the sliding cooperation between the guide band and the first displacement component, the first elastic band can achieve a wide range of lateral position adjustment. Through the sliding cooperation between the second displacement component and the first elastic band, the fixing mechanism and the clamped probe can achieve a wide range of longitudinal position adjustment. Together, they form an XY-axis two-dimensional adjustment system, enabling precise adjustment of any monitoring point on the entire abdomen of the pregnant woman without repeatedly adjusting the overall fixing position of the belt, thus improving the efficiency of finding and adjusting monitoring points. The synchronously linked clamping structure allows the two clamps to open in opposite directions simultaneously by pressing the pressing plates of the first and second buttons. Releasing the buttons causes the first and second springs to return, simultaneously clamping the probe. This simplifies the operation and improves clinical efficiency.

The first displacement component 3 moves along the guide belt 2. A first elastic belt 4 is installed between the two first displacement components 3 of the two anti-slip bottom belts 1. A second displacement component 5 is installed on the first elastic belt 4. The second displacement component 5 moves along the first elastic belt 4. A fixing mechanism is installed on the second displacement component 5. A binding mechanism is sewn onto both ends of the anti-slip bottom belt 1. The belt body of the monitoring belt is made of medical-grade breathable fabric.

[0020] The fixing mechanism includes a fixing frame 6 integrally formed with the second displacement member 5. A first moving plate 7 and a second moving plate 8 are inserted inside the fixing frame 6. The first moving plate 7 and the second moving plate 8 slide along the inside of the fixing frame 6 and move towards or away from each other. A fixing clip 9 is integrally formed at one end of the first moving plate 7 and the second moving plate 8 that are close to each other. A first crossbar 10 is installed on the side wall of the first moving plate 7. A through hole is opened on the second moving plate 8. The other end of the first crossbar 10 passes through the through hole of the second moving plate 8 and is equipped with a first button 11. The other end of the first button 11 protrudes out of the fixing frame 6. A second crossbar 12 is installed on the side wall of the second moving plate 8. A through hole is opened on the first moving plate 7. The other end of the first crossbar 10 passes through the through hole of the first moving plate 7 and is equipped with a second button 13. The other end of the second button 13 protrudes out of the fixing frame 6.

[0021] A first spring 14 is fitted onto the end of the first crossbar 10 away from the first moving plate 7. One end of the first spring 14 is in contact with the side wall of the first button 11, and the other end of the first spring 14 is in contact with the side wall of the second moving plate 8.

The fixing head of the fixing surface of the fetal heart monitoring probe is placed in the clamping area between the two fixing clips 9. Release the first button 11 and the second button 13. The first spring 14 and the second spring 15 return to their original position and drive the first moving plate 7 and the second moving plate 8 to move away from each other, so that the two fixing clips 9 clamp and limit the fixing head of the fetal heart monitoring probe. S3: Simultaneously fine-tune the lateral arrangement of the two sets of first shifting components 3 along the guide belt 2 on the top surface of the anti-slip bottom belt 1, drive the first elastic belt 4 to move laterally, and then fine-tune the longitudinal arrangement of the second shifting component 5 along the first elastic belt 4. Drive the fixing mechanism and the clamped and fixed monitoring probe to move synchronously through the second shifting component 5 until the probe detection surface is aligned with and closely attached to the target monitoring point on the abdomen, and start fetal heart monitoring.
