Description

Technical Field

[0001] The utility model relates to the technical field of blood glucose detection consumables, and more specifically, to a blood glucose test strip and a storage box for blood glucose test strips. Background Art

[0002] Hypoglycemia refers to too low a level of glucose in the plasma. The inducements of hypoglycemia include organic lesions, such as liver diseases, endocrine diseases or congenital enzyme deficiencies, or some exogenous factors such as improper diet or taking hypoglycemic drugs. Diabetes is a chronic disease mainly caused by insufficient insulin secretion or impaired insulin utilization, marked by hyperglycemia. Whether it is hypoglycemia or diabetes, both require exogenous intervention treatment. In addition, in addition to routine intervention treatment, regular blood glucose detection of patients is also an essential medical examination item, which can enable patients to better master the blood glucose changes of diabetic patients or hypoglycemic patients.

[0003] The blood glucose test strip is used in conjunction with a blood glucose meter. Through the chemical reaction between the bio-enzyme coated on the surface of the blood glucose test strip and glucose in human blood, a weak current is generated. The magnitude of the current is proportional to the glucose concentration of the blood sample. The electronic instrument built into the blood glucose meter measures the current change generated on the surface of the blood glucose test strip and converts the current change into a digital signal, and displays the current blood glucose level of the patient through a display screen.

[0004] Metal electrodes are provided on the surface of the blood glucose test strip, and bio-enzyme is coated on the surface of the metal electrodes. The blood glucose test strip needs to be placed in a dry, clean and relatively enclosed environment to ensure the accuracy of blood glucose detection. When the blood glucose test strip is exposed to a humid environment for a long time, the activity of the bio-enzyme on its surface will gradually decrease or even completely disappear, resulting in deviation of the blood glucose detection result.

[0005] Currently, the electrode connection ends of common blood glucose test strips can be inserted into the blood glucose meter on both the front and back sides; however, only one side of the conventional blood glucose test strip is provided with electrodes. If the blood glucose test strip is inserted incorrectly on the front and back sides, no blood glucose detection result can be obtained.

[0006] Currently, blood glucose test strips on the market are generally packaged in paper boxes or placed in bottles. When taking them, the blood glucose test strips need to be poured out, which is not convenient for taking. In addition, in order to improve the dry environment of the bottle, desiccants are often placed in the bottle. However, when taking the blood glucose test strips, the desiccants will also be poured out, and the desiccants need to be put back into the box body many times, which is rather troublesome to use.

[0007] Lancing pens often appear as separate accessories. When using a lancing pen, generally, the pen cap is first disinfected, and then the lancing needle is installed. After use, the lancing pen is not convenient for storage. Some patients measure their blood glucose at home and need to collect fingertip blood for blood glucose testing. After use, the lancing pen may be placed randomly and is easy to lose. In addition, a spring rod is placed at the rear end of the existing lancing pen. Before blood collection, the spring rod needs to be pulled backward first, which is not conducive to integrating the lancing pen with the blood glucose test strip storage box for convenient use and storage. Therefore, the technical problem that those skilled in the art need to solve is to provide a blood glucose test strip with good sealing performance to avoid inserting the positive and negative sides of the electrode wrongly, and a blood glucose test strip storage box with good sealing performance, which integrates the lancing pen with the blood glucose test strip storage box for convenient storage and is not easy to lose.

[0047] The present application provides a blood glucose test strip and a blood glucose test strip storage box to solve the technical problems that the existing blood glucose test strips are exposed to a humid environment for a long time, the sealing of the blood glucose test strips is not tight, the activity of biological enzymes is reduced, resulting in deviation of blood glucose test results, the blood glucose test strips are prone to being inserted incorrectly on the front and back, the existing blood glucose test strips are not easy to take out in the blood glucose test strip storage box, the blood glucose test strip storage box is not tightly sealed, and the existing blood lancet is easily lost when placed separately, and the structure of the existing blood lancet is not convenient for integrated setting with the blood glucose test strip storage box. For this reason, the present application provides the following specific embodiments.

[0048] Embodiment 1

[0049] This embodiment provides a blood glucose test strip. Refer to Figures 1 to 3 , including a substrate 1-1, and the substrate 1-1 is set as a strip-shaped substrate. Refer toFigure 2 The substrate 1-1 is cut from a polyethylene terephthalate plate, a polyvinyl chloride plate, or a polypropylene plate. In this specific embodiment, the substrate 1-1 is cut from a polyethylene terephthalate plate, which has excellent mechanical strength and good mechanical cutting performance.

[0050] An electrode layer 1-2 is laid above the substrate 1-1. Refer to Figure 3 , the length of the electrode layer 1-2 is slightly shorter than that of the substrate 1-1. An anti-misalignment slot 1-1-1 is provided below the substrate 1-1. The anti-misalignment slot 1-1-1 is provided on the back of the electrode end. The electrode end refers to the end of the exposed electrode of the blood glucose test strip, and the electrode end is electrically connected to the metal electrode inside the socket of the blood glucose meter. The anti-misalignment slot 1-1-1 is set as a through slot with a regular shape. The through slot can be a rectangular slot, a semi-circular slot, or a waist-shaped slot. In this specific embodiment, the anti-misalignment slot 1-1-1 is set as a waist-shaped slot, which has good adaptability and insertion convenience. The anti-misalignment slot 1-1-1 can effectively prevent the front and back of the electrode end from being inserted wrongly and improve the insertion convenience of the blood glucose test strip.

[0051] The electrode layer 1-2 is usually made of metal electrodes such as platinum or gold, carbon-silver composite electrodes, and carbon core electrodes. The noble metal electrode has a high sensitivity to detect current changes, but the blood glucose test strip is used as a consumable, and the use cost is relatively high. Although the carbon core electrode has a low price, it is greatly affected by environmental interference, and the measurement result is prone to deviation. In this specific embodiment, the electrode layer 1-2 is made of a carbon-silver composite electrode, which has a low use cost on the premise of ensuring sufficient sensitivity.

[0052] An insulating layer 1-3 is provided above the electrode layer 1-2. The insulating layer 1-3 can be printed with insulating ink above the electrode layer 1-2, or polyethylene plastic coated with pressure-sensitive adhesive is bonded to the upper surface of the electrode layer 1-2. A sampling window is provided on the insulating layer 1-3. When performing blood glucose detection, the blood to be detected is dropped on the sampling window area so that the blood to be detected can undergo an electrochemical reaction with the glucose oxidase provided in the sampling window.

[0053] The length of the insulating layer 1-3 is shorter than that of the electrode layer 1-2, so that the blood glucose test strip has an exposed electrode. When the blood glucose test strip is inserted into the socket of the blood glucose meter, the exposed electrode can be electrically connected to the metal electrode inside the socket of the blood glucose meter and transmit the detected weak current to the blood glucose meter in real time.

[0054] An enzyme layer 1-4 and a hydrophilic layer 1-5 are provided inside the sampling window. The enzyme layer 1-4 adheres to the upper surface of the electrode layer 1-2. The enzyme layer 1-4 includes glucose oxidase, a binder, etc. The reagent enzyme is coated on the upper surface of the electrode layer 1-2, so that the reagent enzyme adheres to the surface of the electrode layer 1-2 to form the enzyme layer 1-4. The enzyme layer 1-4 adheres to the upper surface of the electrode layer 1-2, and a hydrophilic layer 1-5 is provided above the electrode layer 1-2.

[0055] The hydrophilic layer 1-5 is set as the hydrophilic membrane described in the published literature. It is a hydrophilic membrane formed by dissolving fatty alcohol polyoxyethylene ether in an ethylene solution and then drying through a coating drying tunnel. The hydrophilic membrane is coated on the surface of the enzyme layer to siphon the blood to be detected and cause a chemical reaction between the blood to be detected and the glucose oxidase in the enzyme layer to generate a weak current.

[0056] A release film 1-6 is laid on the insulating layer 1-3. Refer to Figure 1 and Figure 3 , the release film 1-6 is divided into a sampling end, a main body, and an electrode end by an easy tear line. The easy tear line is set as a dotted-line easy tear line. The divided release film covers the sampling window, the main body of the insulating layer, and the electrode end respectively, improving the sealing performance of the blood glucose test strip. The release film 1-6 covering the sampling window and the electrode end can effectively prevent the surface bio-enzyme activity of the blood glucose test strip from decreasing due to long-term exposure to a humid environment, resulting in deviation of the blood glucose test result; the release film 1-6 is bonded to the surface of the insulating layer 1-3 through a pressure-sensitive adhesive to improve the bonding performance of the release film 1-6.

[0057] A first easy tear line is provided between the sampling end and the main body. Refer to Figure 1 , a second easy tear line is provided between the electrode end and the main body. The first easy tear line is provided below the sampling window. The first easy tear line is set as a straight easy tear line. The first easy tear line divides the sampling end and the main body. When in use, the sampling end can be separated from the main body along the first easy tear line; it has good sealing performance and is convenient for separating the release film of the sampling end.

[0058] The second easy tear line is provided in the lower space of the release film 1-6. The second easy tear line is opened above the insulating layer 1-3. After tearing the second easy tear line, the release film of the electrode end can be torn off, which is beneficial to improving the sealing performance of the electrode end and is convenient for tearing off the release film above the electrode end, reducing the deviation of the blood glucose test result caused by environmental factors.

[0059] Preferably, the pressure-sensitive adhesive coated on the release film does not include the sampling window area and the area in direct contact with the electrode. Refer to Figure 3When the release film 1-6 is covered above the insulating layer 1-3, the release film above the sampling window opened on the insulating layer 1-3 is not coated with pressure-sensitive adhesive to avoid the influence of the pressure-sensitive adhesive on the water absorption performance of the hydrophilic layer. The release film 1-6 extends downward to cover the electrode end and the lower space of the substrate 1-1. The area covering the electrode end is not coated with pressure-sensitive adhesive, and the pressure-sensitive adhesive is coated on the area where the release film covers the substrate, improving the sealing performance of the electrode end and the tearability of the release film covering the electrode end, and reducing the influence of electrode dampness caused by high environmental humidity on the accuracy of blood glucose detection results.

[0060] Example 2

[0061] This embodiment provides a storage box for blood glucose test strips. Referring to Figures 4 to 13 , it includes a blood glucose test strip as described in Example 1; it further includes a box body 2. Referring to Figures 4 to 7 , a plurality of partitions 2-2 are evenly distributed in the box body 2. Referring to Figure 6 , the plurality of partitions 2-2 intersect horizontally and vertically to form partition spaces, and the blood glucose test strips 1 are distributed in the partition spaces. Referring to Figure 5 .

[0062] The partition 2-2 is set as a corrugated cardboard. Referring to Figure 6 , the corrugated cardboard has high mechanical strength and excellent moisture absorption performance, can adsorb the water vapor in the partition space into the corrugated cardboard space, keep the partition space dry, extend the storage time of the blood glucose test strips placed inside the partition space, and extend the shelf life of the blood glucose test strips.

[0063] A plurality of moisture-absorbing carbon packets 2-3 are distributed on the inner wall of the box body 2. Referring to Figure 7 , activated carbon particles are placed in the moisture-absorbing carbon packets 2-3 to adsorb the humid air in the inner space of the box body 2. The activated carbon particles have a strong dehumidification and moisture-proof effect in the box body space and are adhered to the inner wall of the box body through an adhesive, which can effectively remove the moisture in the air of the inner space of the box body 2, keep the inner space of the box body 2 dry, extend the shelf life of the blood glucose test strips, and reduce the possibility of the enzyme activity of the blood glucose test strips decreasing.

[0064] A box cover 3 is buckled above the box body 2. Referring to Figure 4 , a limiting protrusion 3-1 is provided on the box cover 3. Referring to Figure 8 , the limiting protrusion 3-1 is annularly distributed on the inner wall of the box cover 3, the cross-section of the limiting protrusion 3-1 is set as a semi-circle, and the limiting protrusion 3-1 is set as a convex structure made of soft rubber with a semi-circular cross-section; a limiting groove 2-1 is provided at the corresponding position of the box body 2. Referring to Figure 7, the limiting protrusion 3-1 is adapted to the limiting groove 2-1. The limiting groove 2-1 is set as a semi-circular groove structure adapted to the shape of the limiting protrusion. The distance from the axis of the semi-circular groove to the top surface of the box body is the same as the distance from the limiting protrusion to the inner wall of the top surface of the box cover. The limiting protrusion 3-1 is clamped in the limiting groove 2-1 to improve the tightness and sealing performance of the box cover 3 when it is covered.

[0065] A blood collection pen 4 is integrally connected above the box cover 3. Refer to Figure 8 , the blood collection pen 4 is set as a pressing type blood collection pen. Refer to Figure 9 ; Specifically, the tail end of the blood collection pen 4 is bonded above the box cover 3. The front end of the blood collection pen 4 has a circular plane. Place the finger to be blood collected flat on the blood collection platform. The medical staff holds the box cover 3, aligns the circular plane at the front end of the blood collection pen with the finger to be blood collected, and presses downwards, so that the blood collection needle arranged inside the blood collection pen pierces the capillary vessel of the finger to be blood collected, and the blood drips onto the sampling window to complete blood collection. Compared with the existing mechanical blood collection pen that may be placed randomly and is not easy to store after use, the blood collection pen integrated with the blood glucose test strip storage box in this application can be stored by covering the box cover 3 on the box body 2 after use, and is not easy to lose.

[0066] The blood collection pen 4 includes a pen barrel 4-1. Refer to Figures 10 to 12 , a push rod 4-10 is inserted into the pen barrel 4-1. A push rod sleeve 4-11 is sleeved on the push rod 4-10. The end of the push rod sleeve 4-11 is bonded to the upper surface of the box cover 3. Refer to Figure 4 ; A plurality of first springs 4-4 are evenly distributed on the end surface of the pen barrel 4-1. The two ends of the first spring 4-4 are respectively fixedly connected to the pen barrel 4-1 and the upper surface of the box cover 3. Refer to Figure 8 , the first spring 4-4 is arranged around the push rod 4-10. After blood collection, the first spring 4-4 provides a resilience force to make the pen barrel 4-1 return to its original position and provides stable support for the blood collection pen 4.

[0067] A upper gear 4-9 is arranged below the push rod 4-10. A second limiting ring 4-9-1 is arranged on the inner wall of the upper gear 4-9. A limiting piece is arranged below the push rod 4-10. There are two second limiting rings 4-9-1, and there is a distance between the two second limiting rings 4-9-1. The wall thickness of the limiting piece is adapted to the distance between the two second limiting rings 4-9-1. The limiting piece is clamped between the two second limiting rings 4-9-1, so that the upper gear 4-9 and the push rod 4-10 move reciprocally synchronously.

[0068] A limiting chute 4-1-1 is arranged inside the pen barrel 4-1. Refer to Figure 13, a plurality of the limiting sliding grooves 4-1-1 are provided and are evenly distributed in the circumferential direction on the inner wall of the pen barrel 4-1. A plurality of tooth-shaped notches are formed in the circumferential direction of the upper gear 4-9; the upper gear 4-9 is in contact with the lower gear 4-8. Fins are arranged in the circumferential direction of the lower gear 4-8, and the fins are in contact with the tooth-shaped notches, and the tooth-shaped notches push the lower gear to slide longitudinally.

[0069] The length of the limiting sliding groove 4-1-1 is greater than the total length of the upper gear 4-9. When performing fingertip blood collection, after the fin slides a predetermined distance along the limiting sliding groove 4-1-1, the blood collection needle 4-5 pierces the capillary of the finger to be blood collected. The upper gear 4-9 continues to move forward, the fin disengages from the limiting sliding groove, and relative sliding occurs with the tooth-shaped notch. The fin slides to the bottom end of the tooth-shaped notch, and the blood collection needle withdraws from the capillary of the finger; when the pressing force at the front end of the finger is withdrawn, under the resilience of the second spring 4-7, both the lower gear 4-8 and the upper gear 4-9 slide upward. When the upper gear 4-9 slides in place, relative rotation occurs between the lower gear 4-8 and the upper gear 4-9, and the fin slides along the limiting sliding groove 4-1-1 and makes the fin slide into the upper space of the tooth-shaped notch; the blood collection pen of the present application rebounds immediately after piercing the capillary, reducing the contact time between the metal blood collection needle and the capillary, reducing the trauma to the capillary, and being beneficial to the physical health of the patient.

[0070] Preferably, a slider is arranged in the circumferential direction of the upper gear 4-9. Refer to Figure 12 and Figure 13 , the transverse dimension of the slider is adapted to the groove width of the limiting sliding groove 4-1-1, and the upper gear 4-9 reciprocally slides along the limiting sliding groove 4-1-1 so that the blood collection needle 4-5 penetrates out of the pen cap 4-3 or the blood collection needle 4-5 is received in the pen cap 4-3.

[0071] The lower gear 4-8 has a first limiting ring 4-8-1, and the first limiting ring 4-8-1 is arranged on the inner wall of the lower gear 4-8. A connecting rod 4-6 abuts against the first limiting ring 4-8-1, and a blood collection needle 4-5 is arranged below the connecting rod 4-6; when the finger to be blood collected presses the plane at the front end of the pen cap 4-3, both the upper gear 4-9 and the lower gear 4-8 reciprocally slide along the limiting sliding groove 4-1-1, thereby synchronously reciprocating the connecting rod 4-6 and making the blood collection needle 4-5 penetrate out of the pen cap 4-3 or the blood collection needle 4-5 be received in the pen cap 4-3.

[0072] A socket notch is provided below the connecting rod 4-6, and the cross-sectional shape of the socket notch is adapted to the shape of the tail end of the blood collection needle 4-5; preferably, an opening is longitudinally formed in the socket notch, and the arrangement of the opening enables the socket notch to slightly open and close, facilitating the installation and removal of the blood collection needle.

[0073] The first limiting ring 4-8-1 abuts against the connecting rod 4-6, and a plurality of strip-shaped baffles are evenly distributed on the connecting rod 4-6. Refer to Figure 12 , and the strip-shaped baffles are fixed on the connecting rod 4-6; a second spring 4-7 is arranged on the connecting rod 4-6, the second spring 4-7 is arranged through the connecting rod 4-6, the upper part of the second spring 4-7 is connected to the strip-shaped baffle, and the lower space of the second spring 4-7 abuts against the adjusting cylinder 4-2.
