Description

Technical Field

[0001] This invention relates to the field of medical monitoring device technology, specifically a portable gestational diabetes monitoring device for self-management. Background Technology

[0002] Gestational diabetes mellitus (GDM) refers to the onset of hyperglycemia in pregnant women during pregnancy, usually diagnosed in the second trimester (24-28 weeks) via an oral glucose tolerance test (OGTT). Its occurrence is related to increased insulin resistance due to hormonal changes during pregnancy. If the pregnant woman's pancreatic function is insufficient to compensate, blood sugar levels rise. Risk factors include obesity, advanced maternal age, and a family history of diabetes. GDM may increase the risk of gestational hypertension and premature birth in pregnant women, and may also lead to problems such as macrosomia and neonatal hypoglycemia. Through dietary control, appropriate exercise, and insulin therapy when necessary, most patients can effectively manage their blood sugar, ensuring the health of both mother and baby. Postpartum blood sugar usually returns to normal, but the risk of developing type 2 diabetes in the future is higher, requiring regular monitoring.

[0003] The working principle of existing gestational diabetes monitoring devices is mainly based on the measurement of blood glucose levels. A common method is the blood glucose test strip method. The principle is that the enzymes on the test strip (such as glucose oxidase) react with glucose in the blood to produce an electrical signal or color change. By collecting blood from the fingertip, the blood is dropped onto the test strip, and the blood glucose meter measures the reaction result of the test strip and displays the blood glucose value.

[0004] Existing blood glucose meters, such as the one described in application number 202021925676.9, have the following technical solution: the main body is equipped with a touch screen, a power button, indicator lights, a blood glucose monitoring port, a quick-release switch for blood glucose test strips, a scanning module assembly, a scanning module flip switch, and a speaker. The blood glucose meter provided by this utility model obtains patient information through barcode scanning, automatically records the test time and measurement value, and prompts the user to take further measurements using indicator lights of different colors based on the degree to which the measurement value deviates from the normal range.

[0005] However, pregnant women need to perform multiple glucose tolerance tests on their own when monitoring gestational diabetes. They need to have their blood drawn multiple times, both on an empty stomach and after consuming the glucose solution. Blood tests need to be done before and after meals. The blood collection process is quite troublesome, and the process of collecting and testing blood glucose is quite complicated, making it impossible to carry out unified monitoring.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing blood glucose meter. Summary of the Invention

[0008] The purpose of this invention is to provide a portable gestational diabetes monitoring device for self-management, in order to solve the problem that the blood collection process and test strip testing process mentioned in the background art are relatively cumbersome.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A portable gestational diabetes monitoring device for self-management includes a device housing. A display screen is located on the right side of the front of the housing, and a monitoring unit is connected and mounted behind the display screen, with the monitoring unit fixedly mounted inside the right side of the housing. A charging port is located on the rear side of the housing, with a switch below the charging port and an alarm below the switch. A sliding door is located on the left side of the front of the housing, to the left of the display screen. A drawer is located at the bottom of the housing. A first mounting frame is mounted on the upper left side inside the housing, with a moving rod located at the lower inside of the first mounting frame, and a blood collection needle mounted at the bottom of the moving rod. Two clamping plates are located on the lower left side inside the housing, and a second mounting frame is mounted on the upper inside the housing. A test strip box is mounted on the lower left side of the second mounting frame, and a mechanical gripper is mounted on the lower right side of the second mounting frame. A test port is located on the left side of the monitoring unit.

[0011] Preferably, a handle is provided on the right side of the front of the sliding door, and a blood collection port is provided through the bottom of the sliding door, which provides positioning for collecting fingertip blood.

[0012] By adopting the above technical solution, the sliding door is equipped with a handle for easy opening, and the blood collection port facilitates finger positioning for collecting fingertip blood, making the blood collection operation more convenient and accurate, and improving the user's blood collection experience.

[0013] Preferably, the drawer box has a first sliding groove on both the front and back sides, and the drawer box has several partitions inside, with the partitions engaging with the first sliding grooves on the front and back sides to form a left-right adjustment structure.

[0014] Using the above technical solution, the dividers inside the drawer box can be adjusted left and right, allowing users to flexibly divide the drawer space according to actual needs, making it easier to classify and store items that need to be monitored for gestational diabetes, and improving the flexibility and practicality of the device's storage.

[0015] Preferably, a drive motor is installed on the top left side inside the device housing, and a worm gear is connected and installed at the output end below the drive motor, with the bottom of the worm gear rotatably connected to the top of the base inside the device housing.

[0016] Using the above technical solution, starting the drive motor can drive the worm gear to rotate, providing a power source for the movement of other components inside the device, which is the power basis for realizing functions such as blood collection and test strip grabbing.

[0017] Preferably, a first worm wheel is connected and installed on the front side above the worm, and a rotating rod is connected and installed on the first worm wheel, and a limit wheel is connected and installed on the right end of the rotating rod to form a rotating structure.

[0018] Using the above technical solution, when the worm rotates, it can drive the first worm wheel to rotate, which in turn drives the rotating rod to rotate, and at the same time drives the limit wheel to rotate. In conjunction with other components, it can effectively transmit and convert the power of the drive motor, providing power support for the movement of the blood collection needle.

[0019] Preferably, the first mounting frame has a second sliding groove on both the left and right sides, and a sliding block is provided inside the first mounting frame. The left and right ends of the sliding block are connected to a transmission rod, and the transmission rod contacts the limiting wheel to form an intermittent pop-up structure.

[0020] By adopting the above technical solution, the intermittent spring-loaded structure formed by the transmission rod and the limiting wheel causes the transmission rod to stretch to its highest position when the vortex shape of the limiting wheel rotates to its maximum distance. When the limiting wheel rotates to the turning angle position, it contacts the transmission rod and causes the blood collection needle to spring back. Under the action of power, the blood collection needle can achieve regular movement, ensuring that the blood collection action is carried out according to the set program, thereby improving the stability and reliability of the blood collection process.

[0021] Preferably, a bracket is fixedly installed on the lower front side of the first mounting frame, and a crossbar is fixedly installed in the middle of the bracket. Springs are connected to both ends of the crossbar, and the rear ends of the springs are connected to the left and right sides of the transmission rod.

[0022] By adopting the above technical solution, the spring works in conjunction with the bracket, crossbar and other components to buffer and reset the blood collection needle during its movement, thereby avoiding excessive impact on the blood collection needle, protecting the blood collection components and ensuring the accuracy of the blood collection action.

[0023] Preferably, a second worm gear is connected and installed on the front side below the worm, and a reciprocating screw is connected and installed on the right side of the second worm gear, and the threads on the left and right sides of the reciprocating screw are symmetrical to each other.

[0024] Using the above technical solution, the worm gear rotates simultaneously with the second worm wheel. The arrangement of the second worm wheel and the reciprocating lead screw converts the rotation of the worm gear into the rotation of the reciprocating lead screw, providing power for the movement of the clamping plate and achieving stable clamping of the fingers.

[0025] Preferably, each of the reciprocating lead screws is threaded with a clamping plate, and the bottom of the clamping plate is located inside the third slide groove to form a sliding structure. The third slide groove is opened above the bottom platform inside the device housing, and the clamping plate forms a clamping structure for the fingers.

[0026] By adopting the above technical solution, the clamping plate and the third sliding groove form a sliding structure, which can clamp the finger, ensure the stability of the finger position during blood collection, improve the success rate of blood collection, and at the same time ensure that the finger will not shake during the measurement process, thus affecting the test results.

[0027] Preferably, a cylinder is provided inside the bottom surface of the second mounting frame, and a connecting rod is connected and installed below the cylinder. A mechanical gripper is installed at the bottom of the connecting rod, and the mechanical gripper forms a gripping structure for moving the test paper in the test paper box left and right.

[0028] By employing the above technical solution, the cylinder, connecting rod, and mechanical gripper work together to automatically grab the test strips in the test strip box and move them left and right, thereby automating the test strip retrieval process, simplifying the testing procedure, and reducing user operation steps.

[0029] Compared with the prior art, the beneficial effects of the present invention are: this portable gestational diabetes monitoring device for self-management,

[0030] 1. This invention integrates blood collection, test strip grabbing, and blood glucose testing functions into a portable device.

A blood collection needle is installed at the bottom of the moving rod. Two clamping plates are provided on the lower left side inside the device shell, and a second mounting frame is installed on the upper inside the device shell. A test strip box is installed on the lower left side of the second mounting frame. This simplifies the process of gestational diabetes monitoring, reduces the user's operation steps, and improves the ease of use.

[0031] 2. It is equipped with an automated blood collection system. Through mechanical structures such as a drive motor, worm gear, and worm wheel, and an intermittent spring-loaded structure formed by the transmission rod and the limit wheel, when the vortex shape of the limit wheel rotates to its maximum distance, it drives the transmission rod to extend to its highest position. When the limit wheel rotates to the turning angle position, it contacts the transmission rod, causing the blood collection needle to spring back. The blood collection needle can achieve regular movement under the action of power, ensuring that the blood collection action is carried out according to the set program, improving the stability and reliability of the blood collection process, realizing the automatic blood collection function, reducing the user's operating difficulty and discomfort, and is especially suitable for pregnant women.

[0032] 3. The device has a built-in alarm. When pregnant women are performing a self-managed glucose tolerance test, the alarm will remind them of the time before and after meals to conduct the next blood draw. At the same time, it can promptly remind users when blood sugar levels are abnormal, helping pregnant women to better manage their blood sugar levels and reduce the risk of gestational diabetes.

When the worm 15 rotates, it can drive the first worm gear 16 to rotate, thereby driving the rotating rod 17 to rotate, and at the same time driving the limit wheel 18 to rotate. The rotating wheel 18, in conjunction with other components, effectively transmits and converts the power of the drive motor 14, providing power support for the movement of the blood collection needle 27. The intermittent spring-loaded structure formed by the transmission rod 22 and the limiting wheel 18 causes the transmission rod 22 to stretch to its highest position when the vortex shape of the limiting wheel 18 rotates to its maximum distance. When the limiting wheel 18 rotates to the turning angle position and contacts the transmission rod 22, it causes the blood collection needle 27 to spring back. Under the action of power, the blood collection needle 27 can achieve regular movement, ensuring that the blood collection action is carried out according to the set program, improving the stability and reliability of the blood collection process. The spring 25, in conjunction with the bracket 23, crossbar 24 and other components, plays a buffering and resetting role during the movement of the blood collection needle 27, avoiding excessive impact on the blood collection needle 27, protecting the blood collection components and ensuring the accuracy of the blood collection action.

[0051] A second worm gear 28 is connected and installed on the front side below the worm 15, and a reciprocating screw 29 is connected and installed on the right side of the second worm gear 28. The threads on the left and right sides of the reciprocating screw 29 are symmetrical. A clamping plate 30 is threaded to the outer side of the reciprocating screw 29, and the bottom of the clamping plate 30 is located inside the third slide groove 31 to form a sliding structure. The third slide groove 31 is opened above the bottom platform inside the device housing 1, and the clamping plate 30 forms a clamping structure for the finger. When the worm 15 rotates, it drives the second worm gear 28 to rotate at the same time. The arrangement of the second worm gear 28 and the reciprocating screw 29 converts the rotation of the worm 15 into the rotation of the reciprocating screw 29, providing power for the movement of the clamping plate 30, and realizing stable clamping of the finger. The clamping plate 30 and the third slide groove 31 form a sliding structure and can clamp the finger, ensuring the stability of the finger position during blood collection, improving the success rate of blood collection, and ensuring that the finger does not shake during the measurement process, thus affecting the test results.

[0052] A cylinder 33 is installed inside the bottom surface of the second mounting frame 32, and a connecting rod 34 is connected and installed below the cylinder 33. A mechanical gripper 35 is installed at the bottom of the connecting rod 34, and the mechanical gripper 35 forms a gripping structure for moving the test paper in the test paper box 36 left and right. The cooperation of the cylinder 33, the connecting rod 34 and the mechanical gripper 35 can automatically grip the test paper in the test paper box 36 and move it left and right, realizing the automation of test paper retrieval, simplifying the testing process and reducing user operation steps.

[0053] Working principle:

[0054] In use, the user places their finger inside the blood collection port 5, activates the switch 8, and the drive motor 14 starts working, driving the worm gear 15 to rotate. The worm gear 15 drives the limit wheel 18 to rotate through the first worm wheel 16 and the rotating rod 17. This, in turn, through the linkage of the transmission rod 22 and the sliding block 21, causes the moving rod 26 to move downward, pushing the blood collection needle 27 to collect blood. After blood collection, the spring 25 returns the moving rod 26 to its original position, completing one blood collection operation. After blood collection, the cylinder 33 starts, driving the connecting rod 34 and the mechanical gripper 35 to move downward, grabbing the test strip in the test strip box 36. The mechanical gripper 35 moves the test strip to the test port 13, where the user drips the collected blood. On the test strip, the monitor host 12 reacts with the glucose in the blood through the enzymes on the test strip to generate an electrical signal, thereby calculating the blood glucose value and displaying the result on the display screen 2. When the monitored blood glucose value exceeds the preset range, the alarm 9 will sound an alarm to remind the user to pay attention to the blood glucose level. The user can add test strips to the test strip box 36 by opening the handle 4 on the sliding door 3, and at the same time disinfect or replace the blood collection needle 27. The charging port 7 on the rear side of the device housing 1 is used to charge the device to ensure long-term use of the device. The drawer box 6 is equipped with several partitions 11. The user can adjust the position of the partitions 11 as needed to store consumables such as test strips and blood collection needles 27.
