Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical testing instruments, in particular to a test paper connector used in a blood glucose meter. Background Art
[0002] A blood glucose meter is an instrument that detects blood glucose in human blood. It uses an electrochemical method and the principle of detecting the current signal generated during the reaction process to react to the blood glucose value. The electrons generated by the reaction of enzymes and glucose pass through the current counting facility, read the number of electrons, and then convert them into glucose concentration readings. Generally, when testing blood glucose concentration, blood is first drawn through a blood glucose test strip. After blood collection, the blood glucose test strip is sent to a blood glucose testing machine. After the test is completed, the blood glucose value is read. After the test is completed, the blood glucose test strip is pulled out and discarded.
[0003] Generally, most blood glucose meter connectors are 4-pin to 6-pin connectors, and most of the terminals are assembled. The terminals are the same length, and the terminals may be deformed, scratched or even broken during the assembly process. The data transmission is relatively simple, and the ordinary assembly method is easy to fall off. Moreover, in the existing technology, most blood glucose testers do not have a card return mechanism, and the test piece is clamped manually, which makes it easy for medical staff or users to come into contact with medical waste, increasing the chance of infection. Utility Model Content
[0004] In view of this, an object of the present invention is to provide a test strip connector for a blood glucose meter, which is convenient and quick to insert and remove the test strip.
[0005] To achieve the above purpose, the utility model adopts the following contents:
[0006] The utility model provides a test strip connector for a blood glucose meter, which is installed on an integrated circuit board of the blood glucose meter and includes:
[0007] A socket installed at the front end of the integrated circuit board, the front end of the socket is provided with an opening for inserting the test paper, the interior of the socket is provided with a plurality of parallel and spaced elastic signal terminals, the ends of the signal terminals pass through the rear end of the socket and are then fixed to the integrated circuit board by welding;
[0008] A sliding body located below the socket, and the sliding body can slide relatively in the socket;
[0009] A pusher body installed below the front end of the integrated circuit board, the pusher body is connected to both sides of the sliding body, and is used to push the sliding body to move forward and backward;
[0010] The signal terminal comprises a fixing portion which abuts against but is not connected to the inner upper wall of the socket, and an arc-shaped contact portion whose lower edge slightly protrudes from the surface of the sliding body. When the sliding body moves forward and backward, the contact portion will be slightly lifted upward.
[0011] According to the utility model, a test strip connector for a blood glucose meter also includes a card ejection body disposed below the push body, the card ejection body is connected to the push body, a reset spring consistent with the extension direction of the card ejection body is disposed between the end of the card ejection body and the integrated circuit board, and the reset spring is always in a stretched state.
[0012] By adopting the above technical solution, the card ejection body is initially in a static posture and is in the initial position. When the user manually pushes the card ejection body forward, it will drive the pushing body forward together, thereby controlling the forward movement of the sliding body to achieve the purpose of automatically ejecting the test paper from the socket. When the test paper ejection action is successfully completed, the user releases his fingers, and under the action of the reset spring, the card ejection body automatically drives the pushing body and the sliding body back to the initial position. Due to the automatic reset function of the card ejection body, no additional operation is required to reset the sliding body.
[0013] Based on the above solution, the card ejection body is provided with a groove, and a card body capable of being inserted into the groove is correspondingly arranged at the bottom end of the push body.
[0014] By adopting the above technical solution, the card body can be inserted into the groove to achieve a fixed connection between the card ejection body and the push body, which is an uncommon integrated connection method, so as to facilitate subsequent assembly and disassembly.
[0015] Furthermore, the bottom end surface of the card ejection body is provided with a plurality of anti-skid convex grooves, which can increase the friction force when the user's finger contacts the surface of the card ejection body, thereby improving the traction and anti-skid performance.
[0016] According to the test strip connector for a blood glucose meter provided by the utility model, a stopper is provided at the bottom front end of the integrated circuit board to block the sliding body. The limiting effect of the stopper at the front end can prevent the sliding body from excessively moving forward and stop it in time.
[0017] According to the test strip connector for a blood glucose meter provided by the utility model, six parallel and spaced elastic signal terminals are arranged inside the socket, which are three long terminals and three short terminals, and the long terminals and the short terminals are arranged alternately in sequence. In this way, the signal terminals have more contact points with the test strip and the orientation is more comprehensive, which is conducive to the distinction and conduction of data.
[0018] Based on the above solution, the inner upper wall of the socket is recessed inward to form six limiting grooves, which are arranged along the length direction of the socket, and the six limiting grooves correspond to the six signal terminals one by one, and are used to limit the fixing part of the signal terminal. In other words, the signal terminal is assembled into the socket in a pre-embedded molding form, which effectively avoids the problem of terminal deformation or even breakage caused by traditional riveting and welding ends, and improves assembly efficiency.
[0019] Furthermore, the rear of the socket is provided with six through slots, which correspond to the six signal terminals one by one, so that the ends of the signal terminals can pass through. The signal terminals are not fixedly connected to the socket, but are movably plugged, which improves the flexibility of assembling the terminals and the socket.
[0020] According to a test strip connector for a blood glucose meter provided by the utility model, guide rails extending along the length direction of the socket are formed on both sides of the socket, and guide grooves capable of accommodating the guide rails are recessed on both sides of the sliding body, and anti-jump ribs are formed on the upper part of the guide grooves. The consistency of the forward and backward movements of the sliding body is ensured by the relative sliding of the guide rails and the guide grooves, and the anti-jump ribs ensure that the sliding body does not jump or shake during movement.
[0021] According to the test strip connector for a blood glucose meter provided by the utility model, a mounting slot is recessed on the outer wall of the sliding body, and an insert body capable of being inserted into the mounting slot is correspondingly arranged on the upper part of the push body. The push body and the sliding body are also connected in a movable snap connection manner to improve assembly efficiency.
[0022] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure and is easy to use. The test strip can be inserted or removed smoothly and conveniently, effectively reducing the risk of infection caused by manually clamping the test strip, and the connection and fixing effect during the test strip test is better, ensuring the detection stability; the signal terminal occupies less space, thereby effectively reducing the volume of the connector, saving costs, and being suitable for use in smaller-sized blood glucose meters.

DETAILED DESCRIPTION
[0029] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.
[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0031] like Figures 1 to 4 The utility model embodiment provides a test strip connector for a blood glucose meter. The test strip connector is mainly installed on an integrated circuit board 1 inside the blood glucose meter. The test strip connector mainly includes:
[0032] The socket 2 is installed at the front end of the integrated circuit board 1. An open end 21 for inserting a test paper is provided at the front end of the socket 2. The open end 21 extends toward the inside of the socket 2. A plurality of parallel and spaced elastic signal terminals 4 are arranged inside the socket 2. The ends of the signal terminals 4 pass through the rear end of the socket 2 and are then welded and fixed to the integrated circuit board 1.
[0033] The sliding body 3 is located below the socket 2 and can slide relatively inside the socket 2. After the test paper is inserted into the socket 2 through the opening end 21, the test paper will contact the middle surface of the sliding body. The sliding body plays the role of supporting the test paper.
[0034] The pusher 5 is installed below the front end of the integrated circuit board 1 and is connected to both sides of the sliding body 3 to push the sliding body 3 to move forward and backward.
[0035] The signal terminal 4 includes a fixed portion 41 that abuts against but is not connected to the inner upper wall of the socket 2, and a contact portion 42 with an arc-shaped lower edge that slightly protrudes from the surface of the sliding body 3. There is a certain elasticity at the connection between the contact portion 42 and the fixed portion 41. When the sliding body moves back and forth, the contact portion will be slightly pushed upward, that is, as long as the contact portion contacts the surface of the sliding body, the contact portion will slightly deform and rise upward, and the two will always maintain contact.
[0036] The working principle of the test paper connector is as follows: first, the push body 5 drives the sliding body 3 to move forward to approach the open end position of the socket 2, at which time the contact portion 42 of the signal terminal 4 does not contact the surface of the sliding body 3; then, the test paper is inserted into the socket 2 from the open end 21 of the socket 2, and the front end of the test paper will contact the surface of the sliding body 3; the inward insertion action is maintained, and at the same time, the sliding body 3 is driven by the push body 5 to move backward, and the test paper will also move inward with the sliding body 3 until it approaches the contact portion 42 of the signal terminal 4, and finally the contact portion 42 is slightly lifted upward, and the test paper is also smoothly clamped between the contact portion 42 and the sliding body 3, completing the insertion and fixing of the test paper; when the test paper is to be pulled out, it is only necessary to drive the sliding body 3 forward by the push body 5 so that the sliding body 3 does not contact the contact portion 42, and the test paper can be smoothly pulled out.
[0037] In other embodiments, it also includes a card ejection body 6 arranged below the pushing body 5, the card ejection body 6 is connected to the pushing body 5, and a reset spring consistent with the extension direction of the card ejection body 6 is arranged between the end of the card ejection body 6 and the integrated circuit board 1 (not specifically shown in the figure, it is actually located above and behind the end of the card ejection body), and the reset spring is always in a stretched state.
[0038] Initially, due to the stretching effect of the reset spring, the card ejection body is in the initial position, that is, the sliding body is at the inner rear part of the socket. When the user manually pushes the card ejection body forward, it will drive the pushing body forward together, thereby controlling the forward movement of the sliding body to achieve the purpose of automatically ejecting the test paper from the socket. When the test paper ejection action is successfully completed, the user releases his fingers, and under the action of the reset spring, the card ejection body automatically drives the pushing body and the sliding body back to the initial position. Due to the automatic reset function of the card ejection body, no additional operation is required to reset the sliding body.
[0039] Among them, the card ejection body 6 and the pushing body 5 are not fixedly connected, but are movably connected. Specifically, a groove 61 is provided on the card ejection body 6, and a card body 52 that can be inserted into the groove 61 is correspondingly provided at the bottom end of the pushing body 51. By inserting the card body 52 into the groove 61, the assembly connection between the card ejection body 6 and the pushing body 5 can be realized, so as to facilitate subsequent assembly and disassembly.
[0040] In addition, the bottom end surface of the card ejection body 6 is provided with a plurality of anti-skid convex grooves 62. This can increase the friction force when the user's finger contacts the surface of the card ejection body, thereby improving the traction and anti-skid performance.
[0041] In other embodiments, a stopper 11 is provided at the front end of the bottom of the integrated circuit board 1 to block the sliding body 3. The limiting effect of the stopper at the front end can prevent the sliding body from excessively moving forward and stop it in time.
[0042] In this embodiment, six parallel and spaced elastic signal terminals 4 are arranged inside the socket 2, including three long terminals and three short terminals, and the long terminals and the short terminals are arranged alternately in sequence. In this way, the signal terminals have more contact points with the test paper, and compared with traditional terminals of the same length, the orientation is more comprehensive, which is conducive to the distinction and conduction of data.
[0043] The inner upper wall of the socket 2 is inwardly recessed to form six limiting grooves 22, which are arranged along the length direction of the socket 2, and the six limiting grooves 22 correspond to the six signal terminals 4 one by one, and are used to limit the fixing parts 41 of the signal terminals 4. In other words, the signal terminals are assembled into the socket in a pre-embedded molding form, which effectively avoids the problem of terminal deformation or even breakage caused by traditional riveting and welding terminals, and improves assembly efficiency.
[0044] The rear of the socket 2 is provided with six through slots 23, which correspond to the six signal terminals 4 one by one, for the ends of the signal terminals to pass through. The signal terminals are not fixedly connected to the socket, but are movably plugged, which improves the flexibility of the terminal and the socket when assembled.
[0045] In this embodiment, guide rails 24 extending along the length direction of the socket 2 are formed on both sides, and guide grooves 31 capable of accommodating the guide rails 24 are recessed on both sides of the sliding body 3, and anti-jump ribs 32 are formed on the upper part of the guide grooves 31. The relative sliding of the guide rails and the guide grooves ensures the consistency of the forward and backward movements of the sliding body, and the anti-jump ribs ensure that the sliding body does not jump or shake during movement.
[0046] In this embodiment, a mounting slot 33 is recessed on the outer wall of the sliding body 3, and an inserting body 51 that can be inserted into the mounting slot 33 is correspondingly provided on the upper part of the pushing body 5. In actual design, a slot for the inserting body to move smoothly is also provided on the integrated circuit board. The pushing body and the sliding body are also connected in a movable clamping manner to improve assembly efficiency.
[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
