Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a connector for a blood glucose meter and a uric acid meter. Background Technology

[0002] Blood glucose meters and uric acid meters use electrochemical methods to detect blood glucose and uric acid, reflecting their concentration through current signals. During testing, blood is drawn using test strips, which are then inserted into the machine to read the value. After testing, the test strip is removed and discarded.

[0003] The existing Chinese patent document with patent publication number CN214478056U discloses a novel connector for blood glucose meters.

[0004] However, when addressing the technical problem it raised—that "most blood glucose meter connectors are 4-pin to 6-pin connectors, and the terminals are mostly assembled with the same length, which can lead to terminal deformation, scratches, or even breakage during assembly, resulting in limited data transmission and easy detachment with ordinary assembly methods"—the patent document proposes the following technical solution: A novel blood glucose meter connector includes a terminal assembly, a molded part, a core, push rods, and a housing. The terminal assembly consists of ten terminals: five long terminals and five short terminals, staggered in sequence. The terminal assembly and the molded part are integrally cast using a pre-embedded method. The molded part with terminals is assembled to the rear end of the core using a snap-fit ​​method. The front end of the core has an insertion port for inserting a blood glucose test strip and making electrical contact with the terminal. The upper end of the core has two push rods for pushing the blood glucose test strip out of the insertion port. The upper end of the core is covered with a housing.

[0005] Based on the technical means employed in the aforementioned patent documents, and in conjunction with the accompanying drawings of the patent document, it can be seen that the structure of the connector for the blood glucose meter disclosed in the patent document is as follows: the ten terminals are arranged in a straight line, the circuit board surface area is large, the terminal spacing is too dense, the test strip is in contact on one side only, and the contact points of the test strip are too dense, resulting in a small contact area, leading to unstable contact or short circuits and other defects; at the same time, the layout of the circuit board in the finished product needs to be optimized.

[0006] In summary, its structure still needs further optimization;

[0007] Therefore, a novel connector for blood glucose meters and uric acid meters is proposed. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology, effectively avoid problems such as interference from inserting and removing test strips and large-area scratches, and provide more contact points at the insertion end terminals, resulting in better contact and more comprehensive positioning, which helps to distinguish and transmit data, and can automatically push the test strip out from the insertion port.

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

[0010] A connector for a blood glucose meter and a uric acid meter includes a terminal assembly, a molded part, a core, push rods, and a housing. The terminal assembly consists of ten terminals, namely five long terminals and five short terminals. The terminal assembly is inserted into the molded part, which is assembled at the rear end of the core. Push rods for pushing out blood glucose test strips are provided on both sides of the upper end of the core. The housing is fitted onto the upper end of the core. The ten terminals are inserted into the molded part by an automatic insertion machine, with the long and short terminals arranged correspondingly to form five sets of contact terminals.

[0011] Furthermore, the front end of the core is provided with an insertion port for inserting a blood glucose test strip and contacting the terminal assembly, and the insertion port corresponds centered to the gap between the long terminal and the short terminal.

[0012] Furthermore, the terminal assembly includes five long terminals and five short terminals with welding pins that are staggered on the same plane and the same line to form ten contact welding pins corresponding to ten welding points on the circuit board.

[0013] Furthermore, the molded part and the core are made of LCP special engineering fireproof plastic raw material.

[0014] Furthermore, a push rod slider is installed on the inner side of the push rod near the insertion port. The push rod slider has a test paper pushing protrusion on its side, which extends into the insertion port. By pushing the push rod, the test paper pushing protrusion is pushed out to push out the test paper, thus avoiding direct contact between personnel and the tested test paper.

[0015] Furthermore, the upper end of the rubber core is provided with sliding grooves on both sides for installing push rods. The sliding grooves are provided with slider grooves near the insertion port. The slider grooves are connected to the insertion port. The slider grooves are provided with rectangular protrusions at the bottom, and the lower end of the push rod sliders is provided with rectangular grooves that cooperate with the rectangular protrusions to slide.

[0016] Furthermore, the housing is made of stainless steel, and a fixing groove is provided corresponding to the slider groove, and the push rod slider is slidably connected in the fixing groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Long and short terminals are arranged in a corresponding manner to form five sets of contact terminals (existing connectors on the market have ten terminals arranged in a straight line). This results in a smaller proportion of the circuit board surface area, better optimization of the finished product appearance and circuit board layout, better flexibility, and effectively reduced friction of the insertion and removal test paper. This makes insertion and removal smoother, avoids large-area scratches on the test paper, helps with data differentiation and transmission, and effectively avoids poor contact on one side of the test paper, which may lead to test data errors.

[0019] 2. The upper end of the core is equipped with two push rods for pushing blood glucose test strips or uric acid test strips out of the insertion port, which can automatically push the test strip out of the insertion port and discard it, avoiding direct contact between personnel and test strips.

[0020] 3. The stainless steel cover has a fixed groove. The fixed groove presses the push rod slider tightly to prevent excessive shaking. The push rod slider is slidably connected to the fixed groove to ensure smooth sliding without dryness or jamming. Attached Figure Description

[0034] Example 1

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a connection for a blood glucose meter and a uric acid meter, including a terminal assembly 1, a molded part 2, a core 3, a push rod 4, and a housing 5. The terminal assembly 1 consists of ten terminals, namely five long terminals and five short terminals. The terminal assembly 1 is inserted into the molded part 2, and the molded part 2 is assembled at the rear end of the core 3. Push rods 4 for pushing out blood glucose test strips are provided on both sides of the upper end of the core 3. The housing 5 is installed on the upper end of the core 3. The ten terminals are inserted into the molded part 2 by an automatic insertion machine, with the long terminals and short terminals arranged correspondingly to form five sets of contact terminals.

[0036] Among them, the terminal assembly 1 includes five long terminals and five short terminals with welding feet that are staggered on the same plane and the same line to form ten contact welding feet that correspond to ten welding points on the circuit board, effectively saving the planar space of the circuit board and making the structure more compact.

[0037] Example 2

[0038] like Figure 1-4 As shown, the front end of the core 3 is provided with an insertion port 31 for inserting the blood glucose test strip and contacting the terminal assembly 1. The insertion port 31 is centered and corresponds to the gap between the long terminal and the short terminal. The test strip is elastically inserted into the test port to ensure smooth and good contact.

[0039] The molded part 2 and the core 3 are made of LCP special engineering fireproof plastic raw material.

[0040] A push rod slider 41 is installed on the inner side of the push rod 4 near the insertion port 31. The push rod slider 41 has a test paper push protrusion 42 on its side. The test paper push protrusion 42 extends into the insertion port 31. By pushing the push rod 4, the test paper push protrusion 42 is driven to push out the test paper, thus avoiding direct contact between personnel and the tested test paper.

[0041] The upper end of the core 3 is provided with sliding grooves 32 on both sides for installing push rod 4. The sliding groove 32 is provided with a slider groove 33 near the insertion port 31. The slider groove 33 is connected to the insertion port 31. The slider groove 33 is provided with a rectangular protrusion at the bottom, and the lower end of the push rod slider 41 is provided with a rectangular groove that slides in cooperation with the rectangular protrusion.

[0042] The housing 5 is made of stainless steel, which increases the overall rigidity, avoids product cracking and other defects, improves the surface flatness of the product, and helps the pick and place machine to adsorb. The corresponding slider groove 33 is provided with a fixing groove 51. The fixing groove 51 presses the push rod slider 41 to prevent excessive shaking, and the push rod slider 41 is slidably connected in the fixing groove 51. At the same time, the push rod slider 41 is slidably connected in the fixing groove 51 to ensure that the push rod slider 41 slides smoothly without dryness or jamming.

[0043] The working process of this utility model is as follows: The user inserts the blood glucose test strip into the insertion port 31 at the front end of the core 3. The blood glucose test strip contacts the long terminal and short terminal of the terminal assembly 1 to establish an electrical connection. After the blood glucose test strip contacts the terminal assembly 1, the blood glucose meter or uric acid meter starts to perform the test. During the test, current passes through the blood glucose test strip, and the blood glucose or uric acid level is measured according to the change in current. After the test is completed, the user pushes the push rod 4, and the push rod slider 41 and the test strip protrusion 42 on the inner side of the push rod 4 move accordingly. The test strip protrusion 42 extends into the insertion port 31, pushing out the used blood glucose test strip. This process avoids direct contact between personnel and the tested test strip, reducing the risk of cross-infection.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
