Description

Technical Field

[0001] The invention relates to the technical field of abdominal belts, and more specifically, to an abdominal belt with a pressure sensing alarm function. Background Art

[0002] A belly belt is a kind of belly belt that uses physical methods to help tighten the abdomen. It is divided into postpartum and non-postpartum ones. The postpartum one is designed to relieve the relaxation of abdominal muscles after childbirth and prevent sagging of internal organs. The non-postpartum one is also called a belly belt, which is for people who have undergone abdominal surgery or abdominal organ injuries. When it is for people who have undergone abdominal surgery or abdominal organ injuries, it can sense the incidental pressure on the human abdomen. When the pressure is too high, it will sense and alarm, which is convenient for medical staff to judge the changes in the patient's condition, so as to effectively adjust the tightness of the belly belt and ensure that the belly belt is in a certain pressure state to wrap the abdomen.

[0003] However, the principle of the change in resistance of a material after being compressed is used to convert the pressure into a change in resistance, which is then amplified and processed by a circuit and finally output as an electrical signal. When the pressure is too high, an alarm is triggered. This type of compression pressure sensing requires that the compressed position is fitted to the abdomen, and the abdominal fluctuations generated by human breathing are used to generate pressure. Human skin is relatively soft and is easily deformed when the sensor is squeezed. As a result, when the pressure sensor is subjected to force, part of the pressure is easily buffered by the elastic deformation of the skin, which can easily lead to inaccurate pressure detection and failure to perform a sensing alarm. In addition, after the sensing pressure alarm sounds, the abdominal belt needs to be adjusted for tightness, and the bonded abdominal belt needs to be re-torn, and the bonding position needs to be readjusted to re-wrap the abdomen. As a result, the tightness pressure is not fixed, and the re-bonded position is prone to being too loose or too tight. The adjusted position cannot be accurately adjusted according to the pressure of the human body, and its tightness adjustment is not flexible enough. Summary of the invention

The detection alarm 3 is provided with a rail 31, a force block 32, a limit rod 33, a plastic block 34, and a sensing mechanism 35. The plastic block 34 is embedded in the force block 32, and the limit rod 33 is installed at the lower end of the plastic block 34. The limit rod 33 is movably engaged with the inner side of the rail 31, and the sensing mechanism 35 is located at the same horizontal position as the rail 31. The sensing mechanism 35 is installed in the abdominal belt 1, the rail 31 is embedded in the abdominal belt 1, the force block 32 is installed on the side of the abdominal belt 1, and the limit rod 33 is installed on the lower end of the plastic block 34. It can move in the rail 31 and can be engaged after moving. The anti-slip layer 2 is made of rubber material, which has the characteristics of easy stretching and deformation and high friction, and the thickness of the anti-slip layer 2 is relatively thin. The gap between the force block 32 and the rail 31 is relatively small, so that after the abdominal belt 1 wraps the abdomen, the anti-slip layer 2 fits on the abdomen, and fits on the abdominal skin through the tight pressure to prevent sliding and detachment, and then the sensing mechanism 35 detects the tight pressure of the abdominal belt 1 on the abdomen, and releases the engagement of the limit rod 33 and the rail 31 by pressing the plastic block 34, thereby driving the limit rod 33 to move and engage on the rail 31, so that the force block 32 pulls the abdominal belt 1 to adjust the size of the abdomen it wraps, thereby achieving the effect of flexibly adjusting the wrapping tight pressure and avoiding the need for re-adhesion and inaccurate adjustment.

[0022] Among them, the limiting rod 33 is provided with a slider w1, a movable plate w2, a spring rod w3, and a ball w4, the ball w4 is engaged with the upper end of the slider w1, the movable plate w2 is embedded in the middle of the spring rod w3, the lower end of the spring rod w3 is installed at the bottom of the slider w1, the upper end of the spring rod w3 is embedded in the lower end of the plastic block 34, the ball w4 is slidably matched with the inner side of the rail 31, and the ball w4 is distributed at the upper and lower ends of the slider w1, which has the effect of guiding the sliding, so that the plastic block 34 presses the spring rod w3 downward, so that the movable plate w2 tilts downward and the outer end tilts upward. When tilting up, the movable plate w2 retracts inward and disengages from the engagement of the rail 31, thereby pushing the plastic block 34 to drive the ball w4 at the upper and lower ends of the slider w1 to slide in the abdominal belt 1, and then the plastic block 34 pulls the force-bearing block 32 to adjust the ring wrapped by the abdominal belt 1, so that the tightness of the abdominal belt 1 can be adjusted when wrapping the abdomen.

[0023] The movable plate w2 is provided with a circular plate w21, a block w22, a deformation plate w23, and an inclined plate w24.

The deformation plate w23 is made of rubber and has a deformation effect. The inclined plate w24 is in a state where the outer end is wide and the inner end is narrow. The block w2 2 is the same as the interval size on the inner side of the rail 31, so that the circular plate w21 is driven by the plastic block 34 to translate downward, and then the inclined plate w24 is blocked by the side of the slider w1, so that the deformable plate w23 drives the inclined plate w24 to tilt, and then the position of the block w22 is disengaged from the inner side of the rail 31, and after the plastic block 34 is released, the circular plate w21 translates upward under the elastic force of the spring rod w3, driving the inclined plate w24 to be horizontal, and then the block w22 re-engages with the inner side of the rail 31, achieving the effect of pressing to release the engagement.

The square rod t3 is arranged at intervals. The blocking plate t2 is located on the side of the inner side of the support plate t1 to form a notch. The size of the notch is the same as that of the limiting rod 33, which has the function of making the limiting rod 33 detach from the rail. The position 31 is loosened to form a strip effect on the abdominal belt 1, and then the abdominal belt 1 is wrapped around the abdomen and the limit rod 33 enters from the gap of the track 31, so that the force-bearing block 32 forms a ring-shaped constraint on the abdomen wrapped by the abdominal belt 1. After the movable plate w2 is disengaged from the engagement of the square rod t3, the upper end of the slider w1 slides and translates on the lower side of the blocking plate t2, and the movable plate w2 is re-engaged in the gap of the square rod t3 after moving, so as to achieve the effect of sliding to adjust the tightness, avoid the need to completely loosen the bonding again, and prevent the tightness adjustment pressure from being inflexible. The specific usage and function of this embodiment are as follows: In the present invention, after the abdominal belt 1 is wrapped around the abdomen, the anti-slip layer 2 is attached to the abdomen and attached to the abdominal skin through the tight pressure to prevent sliding and detachment. Then the sensing mechanism 35 detects the tight pressure of the abdominal belt 1 on the abdomen, and presses the spring rod w3 downward through the plastic block 34, so that the movable plate w2 tilts downward and the outer end tilts upward. When tilting up, the movable plate w2 retracts inward and disengages from the track 31, and then pushes the plastic block 34 to drive the balls w4 at the upper and lower ends of the slider w1 to slide in the abdominal belt 1, and then the plastic block 34 pulls the force-bearing block 32 to adjust the ring wrapped by the abdominal belt 1, so that the tightness of the abdominal belt 1 can be adjusted when wrapping the abdomen, thereby achieving the effect of flexibly adjusting the wrapping tightness pressure and avoiding the need for re-bonding and inaccurate adjustment.

[0025] In the present invention, after the abdominal belt 1 is wrapped around the abdomen, the limiting rod 33 enters from the notch of the rail 31, thereby driving the force block 32 to form an annular constraint on the abdomen wrapped by the abdominal belt 1, and then the circular plate w21 in the movable plate w2 is driven by the plastic block 34 to translate downward, and then the inclined plate w24 is blocked by the side of the slider w1, so that the deformable plate w23 drives the inclined plate w24 to tilt, and then the position of the block w22 is disengaged from the square rod t3, and after the plastic block 34 is released, the circular plate w21 translates upward under the elastic force of the spring rod w3, so that the block w22 is disengaged from the engagement of the square rod t3, and then the upper end of the slider w1 slides and translates on the lower side of the blocking plate t2, and after the position is moved, the movable plate w2 is re-engaged in the gap of the square rod t3, so as to achieve the effect of sliding to adjust the tightness, avoid the need to completely loosen the bonding again, and prevent the tightness adjustment pressure from being inflexible. Example

The resistor sensor s7 is connected to the power supply s5. s5 circuit connection, the elastic rod s2 is embedded in the inner side of the second terminal s6 and the first terminal s1, the power supply s5, the resistance sensor s7, the first terminal s1 and the second terminal s6 are respectively arranged and embedded in the inner side of the abdominal belt 1, the resistance sensor s7 is on the same plane as the track 31, the outer end surface of the resistance sensor s7 is provided with a display, and has an alarm ringing effect, the second terminal s6 and the first terminal s1 are provided with a plastic shell, the elastic rod s2 is embedded in the inner side of the plastic shell, the The outermost layer inside the first terminal s1 and the second terminal s6 is provided with a sponge material plate, which has a semi-sealing effect on the outside. The elastic rods s2 are provided with four, which are distributed in a square shape around the resistance rod s3 and the sliding sheet s4, and have the effect of stabilizing the resistance rod s3 and the sliding sheet s4. Therefore, the power supply s5 provides current to the resistance sensor s7, so that the second terminal s6 connected to the resistance sensor s7 forms a closed loop with the first terminal s1, and then the abdominal pressure after the abdominal belt 1 wraps the abdomen will make the abdominal belt 1 in a tight state, and then The tension of the abdominal band 1 drives the second terminal s6 and the first terminal s1 to stretch under the elastic force of the elastic rod s2, thereby driving the resistance rod s3 and the sliding sheet s4 to slide, so that the resistance sensor s7 senses the change in resistance in the closed loop, thereby converting the tension pressure between the abdominal band 1 into resistance force. The pressure of the resistance conversion is displayed on a display outside the resistance sensor s7. When the pressure exceeds the limit, an alarm rings to prevent the abdominal skin from having soft deformation when sensing pressure by contacting the skin, thereby avoiding affecting the accuracy of pressure sensing.

A ball is provided on the outer side of the circular rod s23, which has a guiding sliding effect. When the first terminal s1 and the second terminal s6 are stretched, the circular rod s23 and the sliding rod s22 are driven to slide. Under the elastic force of the spring s21, the first terminal s1 and the second terminal s6 are moved back and forth under the change of the tension force, and then the sliding of the sliding rod s22 and the circular rod s23 ensures that the first terminal s1 and the second terminal s6 are in a horizontal active state, preventing the sliding between the sliding sheet s4 and the resistance rod s3 from being affected. The specific usage and function of this embodiment are as follows: In the present invention, the power supply s5 provides current to the resistance sensor s7, so that the second terminal s6 connected to the resistance sensor s7 forms a closed loop with the first terminal s1, and then the abdominal pressure after the abdominal band 1 is wrapped around the abdomen will make the abdominal band 1 in a tight state, and then the tightness of the abdominal band 1 drives the second terminal s6 and the first terminal s1 to stretch under the elastic force of the elastic rod s2, and at the same time drives the circular rod s23 and the sliding rod s22 to slide, and under the elastic force of the spring s21, the first terminal s1 and the second terminal s6 move back and forth under the change of the tension, and then the sliding of the sliding rod s22 and the circular rod s23 ensures that the first terminal s1 The first terminal s1 and the second terminal s6 are in a horizontally active state to prevent affecting the sliding between the sliding piece s4 and the resistance rod s3, so that the first terminal s1 and the second terminal s6 are pulled outward by the tight pressure of the abdominal band 1, and then drive the resistance rod s3 and the sliding piece s4 to slide, so that the resistance sensor s7 senses the change of resistance in the closed loop, thereby converting the tight pressure between the abdominal band 1 into resistance force, and the pressure of the resistance conversion is displayed on the display outside the resistance sensor s7.
