[0049] This solution has the following working process: when recording the patient's blood sugar test data, by manually pressing the pressing block 201 corresponding to the test data, the pressing block 201 moves to drive the movable column 203 to move, so that the first spring 202 is compressed, the movable column 203 moves to push the pushing block 200 to move, the pushing block 200 moves to move the bottom rod 104, the bottom rod 104 moves to compress the second spring 300, at this time the pushing block 200 is engaged with the positioning block 102, the pressure on the pressing block 201 is released, at this time the second spring 300 releases the elastic force to push the bottom rod 104, so that the pushing block 200 and the positioning block 102 are more stably engaged, at this time the blood sugar test data is recorded, and the following steps are performed. During a blood sugar test, medical staff can obtain the last blood sugar data by observing the data on the pressing block 201 after the last press. When recording the next blood sugar test data, press the pressing block 201 on the corresponding data to move the bottom rod 104, compress the second spring 300, separate the last engaged push block 200 from the positioning block 102, and contract the first spring 202 to pull the last push block 200 back to its original position. At this time, the push block 200 is engaged with the positioning block 102, and the pressure on the pressing block 201 is released. At this time, the second spring 300 releases the elastic force to push the bottom rod 104, so that the push block 200 and the positioning block 102 are more stably engaged, and the blood sugar test data of this time is recorded.

[0050] When resetting the pressing block 201 on the device, the pressing block 201 opposite to the smoothing block 103 is manually pressed to move the bottom rod 104. At this time, the pushing block 200 engaged with the positioning block 102 is reset, so that all the pressing blocks 201 are restored to their original positions.

[0051] When prompting the medical staff, after a blood sugar test and data recording are completed, the medical staff operates the PLC controller 800 to set the rotation time of the servo motor 604. When the preset time is reached, the PLC controller 800 controls the servo motor 604 to rotate back and forth. The reciprocating rotation of the servo motor 604 drives the rack 602 to move back and forth, and then drives the rotating rod 502 to rotate back and forth, continuously knocking the copper bell 700. After hearing the sound, the medical staff can come over to test the patient's blood sugar again.

[0052] According to the above working process, it can be known that: by setting the positioning block 102 and the pushing block 200, the position of the pressing block 201 after being pressed can be fixed, by setting the second spring 300, the engagement of the positioning block 102 and the pushing block 200 is more stable, by setting the first spring 202, after the positioning block 102 is separated from the pushing block 200, the pressing block 201 can be pushed back to the original position by the first spring 202, and by setting the smoothing block 103, the position of the pressing block 201 can be restored to its original position, so that the patient's blood sugar test data can be effectively recorded, avoiding the situation where errors in manual data recording are avoided.

[0053] By means of the servo motor 604, the toothed column 603 and the rack 602, the connecting disk 507 can make reciprocating motion, by means of the connecting rod 505, the rotating rod 502 can make reciprocating rotation, and by means of the striking ball 503, the copper bell 700 can be struck back and forth to emit a prompt sound, thereby being able to regularly remind medical staff and reducing their workload.

[0054] Further as Figure 2 As shown, a support frame 605 is fixed to the other side of the bottom surface of the inner wall of the housing 100 , a servo motor 604 is fixed to the top surface of the support frame 605 , a toothed column 603 is fixed to the output end of the servo motor 604 , and the toothed column 603 is meshed with the rack 602 .

[0055] The servo motor 604 is provided to make the toothed column 603 rotate back and forth, thereby making the rack 602 reciprocate, thereby achieving continuous striking of the copper bell 700.

[0056] Further as Figure 1 As shown, a PLC controller 800 is fixed on one side of the top surface of the housing 100 , and the servo motor 604 is electrically connected to the PLC controller 800 .

[0057] By setting up the PLC controller 800, medical staff can set the rotation time of the servo motor 604 by operating the PLC controller 800, so as to serve as a reminder to the medical staff.

[0058] Further as Figure 3 As shown, the outer side wall of the sleeve column 500 is provided with a plurality of side openings 508 distributed in a circumference, and there are eight side openings 508 , and the connecting rod 505 movably passes through the corresponding side openings 508 .

[0059] The side opening 508 is provided so that the connecting rod 505 can pass through the sleeve 500 , thereby facilitating the rotation of the connecting rod 505 .

[0060] Further as Figure 5As shown, two limiting grooves 400 are provided on the bottom surface of the inner side wall of the outer frame 101 , and two clamping strips 401 are fixed on the bottom surface of the bottom rod 104 , and the clamping strips 401 are movably engaged in the corresponding limiting grooves 400 .

[0061] By providing the clamping strip 401 and the limiting groove 400 , the position of the bottom bar 104 can be further limited, thereby enabling the bottom bar 104 to move stably.

[0062] Further as Figure 1 As shown, two mounting blocks 900 are respectively fixed to two opposite side surfaces of the outer wall of the housing 100, and screws 901 are movably connected to the top surfaces of the mounting blocks 900.

[0063] The housing 100 can be fixed on the wall by means of the provided mounting block 900 and the screws 901 .

[0064] In summary: when recording the patient's blood sugar test data, the pressing block 201 corresponding to the test data is manually pressed, and the pressing block 201 moves to drive the movable column 203 to move, so that the first spring 202 is compressed, and the movable column 203 moves to push the pushing block 200 to move, and the pushing block 200 moves to move the bottom rod 104, and the bottom rod 104 moves to compress the second spring 300. At this time, the pushing block 200 is engaged with the positioning block 102, and the pressure on the pressing block 201 is released. At this time, the second spring 300 releases the elastic force to push the bottom rod 104, so that the pushing block 200 and the positioning block 102 are more stably engaged. At this time, the blood sugar test data is recorded, and the next blood sugar test is performed. During the test, the medical staff can observe the data on the pressing block 201 after the last press to obtain the last blood sugar data. When recording the next blood sugar test data, press the pressing block 201 on the corresponding data to move the bottom rod 104, and the second spring 300 is compressed. The last engaged push block 200 is separated from the positioning block 102, and the first spring 202 contracts to pull the last push block 200 to reset. At this time, the push block 200 is engaged with the positioning block 102, and the pressure on the pressing block 201 is released. At this time, the second spring 300 releases the elastic force to push the bottom rod 104, so that the push block 200 and the positioning block 102 are more stably engaged, and the blood sugar test data this time is recorded.

[0065] When resetting the pressing block 201 on the device, the pressing block 201 opposite to the smoothing block 103 is manually pressed to move the bottom rod 104. At this time, the pushing block 200 engaged with the positioning block 102 is reset, so that all the pressing blocks 201 are restored to their original positions.

[0066] When prompting the medical staff, after a blood sugar test and data recording are completed, the medical staff operates the PLC controller 800 to set the rotation time of the servo motor 604. When the preset time is reached, the PLC controller 800 controls the servo motor 604 to rotate back and forth. The reciprocating rotation of the servo motor 604 drives the rack 602 to move back and forth, and then drives the rotating rod 502 to rotate back and forth, continuously knocking the copper bell 700. After hearing the sound, the medical staff can come over to test the patient's blood sugar again.

[0067] The servo motor 604, the copper bell 700 and the PLC controller 800 can be purchased on the market, and are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
