Description

Technical Field

[0001] The utility model belongs to the technical field of blood glucose meters, and in particular relates to a test paper returning device for a blood glucose meter. Background Art

[0002] Diabetes is an incurable chronic disease. Long-term existence can lead to chronic damage and dysfunction of various tissues. Severe patients are more likely to have long-term complications, such as cardiovascular disease, stroke, chronic kidney disease, diabetes and retinopathy, which bring pain to the lives of diabetic patients. At present, there are more than 100 million diabetic patients in my country, who need to undergo regular blood sugar testing.

[0003] Blood glucose meter, also known as glucometer, is an electronic instrument that measures blood glucose level. Blood glucose meter is divided into photoelectric type and electrode type based on working principle. The test principle of electrode type blood glucose meter is more scientific, and the electrode can be hidden inside. Blood glucose meter has two kinds of working principles, one is photoelectric type and the other is electrode type. Photoelectric blood glucose meter is similar to CD player, with a photoelectric head. Its advantage is that it is relatively cheap, and its disadvantage is that the detection head is exposed to the air, which is easily contaminated, affecting the test results. The error range is about plus or minus 0.8, and the service life is relatively short. Generally, it is more accurate within two years. After two years, it is recommended that patients who are using photoelectric type machine go to the maintenance station for calibration. Generally, hospital representatives will perform regular maintenance, while home blood glucose meter needs to go to the after-sales service department for head maintenance. The test principle of electrode type is more scientific, and the electrode port is hidden inside to avoid contamination. The error range is generally about plus or minus 0.5. It has high accuracy, does not require calibration under normal use, and has a long service life. There are two types of blood collection methods for blood glucose meter, one is blood smearing type and the other is blood sucking type. Blood smearing machine generally collects a large amount of blood, which is painful for patients. If too much blood is collected, the test results will be affected. If the blood volume is insufficient, the operation will fail and the test strip will be wasted. Most of these blood glucose meters are photoelectric. In blood-sucking blood glucose meters, the test strip controls the blood sample measurement by itself, and the result will not be biased due to the blood volume problem. It is easy to operate and only requires a drop of blood to be touched with the test strip.

[0004] After the test is completed, the existing blood glucose meter usually needs to manually pull out the test strip with blood, which causes the user's hand to directly contact the test strip. If the user's hand has scratches or wounds, it is easy to get wound infection after contact with the test strip. If the user uses other tools such as clips or tweezers to pull out the test strip, the use of the blood glucose meter will be cumbersome, thereby increasing the burden on the user.

[0005] Therefore, a blood glucose meter test strip removal device is needed to solve the problems in the prior art of manually removing the test strip, which easily causes the blood on the test strip to come into contact with the wound on the user's hand, thereby causing wound infection, and using auxiliary tools to pull out the test strip, which is cumbersome and increases the burden on the user. Utility Model Content

[0006] The purpose of the utility model is to provide a blood glucose meter test strip removal device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blood glucose meter test strip ejection device, comprising a blood glucose meter body, a side opening being opened on one side of the blood glucose meter body, side rods being fixed on both sides of the bottom surface of the inner wall of the side opening, two side rods being rotatably connected with a rotating shaft between the two side rods close to the top of one side, symmetrically distributed paper ejection wheels being fixed on the outer wall of the rotating shaft, a gear being fixed on one side of the outer wall of the rotating shaft, a limiter being fixed on one side of the inner wall of the side opening, a toothed ring being rotatably connected in the limiter, the gear being meshed with the toothed ring, two top openings being opened on one side of the top surface of the blood glucose meter body, and the toothed ring passing through the two top openings.

[0008] It should be noted in the solution that a guide plate is fixed to the bottom surface of the inner side wall of the side opening, and guide grooves are respectively provided on the inner side walls of the guide plate near the bottom of one side surface.

[0009] It is further worth noting that a plurality of rubber strips distributed in a circumference are fixed to the outer side wall of the paper ejection wheel.

[0010] It should be further explained that a plurality of anti-slip strips distributed in a circumference are fixed to the outer side wall of the toothed ring, and the anti-slip strips are rectangular structures.

[0012] As a preferred implementation, a detection head is fixed to one side of the top surface of the inner side wall of the side opening.

[0013] Compared with the prior art, the blood glucose meter test strip removal device provided by the utility model has at least the following beneficial effects:

[0014] By means of the toothed ring and gear, the rotation of the toothed ring can drive the gear to rotate, thereby driving the rotating shaft to rotate, so that the two paper-returning wheels can rotate; by means of the paper-returning wheel and rubber strip, the test paper can be stably driven by the paper-returning wheel and the rubber strip, thereby facilitating the taking out and putting in of the test paper; by means of the guide plate and guide groove, the position of both sides of the test paper can be limited, thereby making the taking out of the test paper more convenient, reducing the burden on the user, and avoiding the manual taking out of the test paper, which may cause the blood on the test paper to come into contact with the wound on the user's hand, thereby causing wound infection.

[0034] Further as Figure 2 As shown, a guide plate 400 is fixed to the bottom surface of the inner wall of the side opening 102 , and guide grooves 401 are respectively formed at the bottom of the inner walls of the guide plate 400 close to one side.

[0035] The guide plate 400 is provided so that the test paper can be placed on the bottom surface of the inner wall of the guide plate 400, and the guide groove 401 is provided so that the positions of both sides of the test paper can be limited, thereby facilitating the test paper to move into the side opening 102 along a straight line.

[0036] This solution has the following working process: when testing the test paper, the test paper is clamped in the guide groove 401 and pushed so that the top surface of the test paper close to the side of the detection head 800 contacts the rubber strip 201 at the bottom of the paper-returning wheel 200, and then the toothed ring 501 is manually rotated, the toothed ring 501 rotates to drive the gear 502 to rotate, the gear 502 rotates to drive the rotating shaft 300 to rotate, the rotating shaft 300 rotates to drive the two paper-returning wheels 200 to rotate, the paper-returning wheels 200 rotate to drive the test paper, and finally the test paper is moved to the position below the detection head 800, the blood glucose meter body 100 is operated, and the detection head 800 detects the blood on the test paper.

[0037] When the test paper is taken out, the toothed ring 501 is manually rotated in the reverse direction to make the paper-retracting wheel 200 rotate in the reverse direction, and the test paper is driven out from the side opening 102 .

[0038] According to the above working process, it can be known that: by means of the toothed ring 501 and the gear 502, when the toothed ring 501 rotates, it can drive the gear 502 to rotate, and then drive the rotating shaft 300 to rotate, so that the two paper-returning wheels 200 rotate; by means of the paper-returning wheels 200 and the rubber strip 201, the test paper can be stably driven by the paper-returning wheels 200 and the rubber strip 201, so that it is convenient to take out and put in the test paper; by means of the guide plate 400 and the guide groove 401, the positions of both sides of the test paper can be limited, so that the removal of the test paper is more convenient, the burden on the user is reduced, and the manual removal of the test paper is avoided, which may cause the blood on the test paper to contact the wound on the user's hand, thereby causing wound infection.

[0039] Further as Figure 2 As shown, a plurality of rubber strips 201 distributed in a circumference are fixed to the outer side wall of the paper ejection wheel 200 .

[0040] The rubber strip 201 is provided to increase the friction between the paper-returning wheel 200 and the test paper, thereby facilitating the paper-returning wheel 200 to drive the test paper to move to a position below the detection head 800 in the side opening 102 .

[0041] Further as Figure 4 As shown, a plurality of anti-slip strips 600 distributed in a circumference are fixed to the outer side wall of the toothed ring 501, and the anti-slip strips 600 are rectangular structures.

[0044] The side opening 102 can be closed by the set block 101 .

[0045] Further as Figure 2 As shown, a detection head 800 is fixed to one side of the top surface of the inner wall of the side opening 102 .

[0046] By setting the detection head 800, the detection head 800 can detect the test paper.

[0047] In summary: when testing the test paper, the test paper is engaged in the guide groove 401 and pushed so that the top surface of the test paper is close to the side of the testing head 800 and contacts the rubber strip 201 at the bottom of the paper-returning wheel 200. Then, the toothed ring 501 is manually rotated, and the rotation of the toothed ring 501 drives the gear 502 to rotate. The rotation of the gear 502 drives the rotating shaft 300 to rotate. The rotation of the rotating shaft 300 drives the two paper-returning wheels 200 to rotate.
