Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical testing technology, specifically to a test strip ejection device and a urine analyzer. Background Technology
[0002] Urine analysis is an important routine test in clinical medicine. Through the chemical reaction between test strips and urine samples, it can quickly detect multiple physiological indicators such as pH, protein, and glucose. Traditional urine analysis requires manually holding one end of the test strip and bringing the other end into contact with the urine to initiate the chemical reaction. The reacted test strip is then inserted into the detection slot of the urine analyzer, where the instrument automatically analyzes and tests the sample. After the test is complete, the test strip is manually removed.
[0003] However, during the testing process, urine may spread throughout the test strip. Therefore, when manually handling the test strip, the operator's hands may come into contact with residual urine on the strip. Since urine samples may contain various pathogens and harmful substances, this increases the risk of infection for the operator. Furthermore, when testing a large number of samples, the operator needs to repeatedly insert and remove the test strip, which is not only time-consuming but also prone to errors due to fatigue, reducing work efficiency. Utility Model Content

[0031] Please refer to Figure 1 In one aspect of this application, a test strip ejection device 100 is provided, which is mounted on a mounting surface and includes a push rod 110, a clamping member 120, and a first return spring 130. The push rod 110 has a locking part 111, a connecting rod 112, and a pushing end 113 arranged sequentially, and the pushing end 113 is used to abut against the test strip 300. The clamping member 120 includes a fixing frame 121, and the inner wall of the fixing frame 121 has a first elastic arm 122 and a second elastic arm 123 extending along the length direction of the push rod 110, the first elastic arm 122 and the second elastic arm 123 being arranged opposite to each other and spaced apart. The locking part 111 of the push rod 110 is detachably engaged between the first elastic arm 122 and the second elastic arm 123. The first return spring 130 is sleeved on the outer periphery of the connecting rod 112, with one end abutting against the outer wall of the fixing frame 121 and the other end abutting against the pushing end 113.
[0032] When the test strip 300 abuts against the push end 113 to drive the push rod 110 to move toward the clamping member 120, the locking part 111 engages between the first elastic arm 122 and the second elastic arm 123, and the first return spring 130 is compressed and stores energy; the first elastic arm 122 and the second elastic arm 123 are driven to move in opposite directions, the first return spring 130 releases energy and drives the push rod 110 to move away from the clamping member 120, so as to eject the test strip 300.
[0033] Specifically, the test strip ejection device 100 is used to quickly eject 300 test strips or 300 test strip sticks after urine analysis is completed. The entire process eliminates the need for operator hand contact with the test strips 300, reducing the possibility of infection due to hand contact with the test strips, as is common in existing technologies. The test strip ejection device 100 is mounted on a flat mounting surface, which both supports the device and ensures the accuracy of the test strip ejection. This mounting surface can be a plane within the urine analyzer 200.
[0034] like Figure 1 As shown, the test strip ejection device 100 includes a push rod 110. The push rod 110 is provided with a locking part 111 for locking with the clamping member 120 along the straight direction in which the test strip 300 is ejected, a pushing end 113 for directly contacting the test strip 300 and transmitting the ejection force, and a connecting rod 112 for connecting the locking part 111 and the pushing end 113.
[0035] In order to improve the reliability of ejection, the push end 113 has a rectangular block structure, and the side that contacts the test paper 300 has a planar structure to increase the contact area with the test paper 300, ensure that the test paper 300 is subjected to uniform force, and can be ejected in a straight line to avoid deviation in the direction of force transmission.
[0036] like Figure 1 As shown, the test strip ejection device 100 also includes a clamping member 120, which includes a fixing frame 121. The fixing frame 121 has a hollow portion for accommodating a first elastic arm 122 and a second elastic arm 123. The same-side ends of the first elastic arm 122 and the second elastic arm 123 are respectively connected to the fixing frame 121, and the other ends of the first elastic arm 122 and the second elastic arm 123 are free ends. Since the first elastic arm 122 and the second elastic arm 123 are opposite to each other and spaced apart, the force can drive them to move in opposite directions, thereby increasing the distance between the free ends of the first elastic arm 122 and the second elastic arm 123.
[0037] like Figure 1As shown, a through hole is provided on one side of the fixed frame 121 near the free ends of the first elastic arm 122 and the second elastic arm 123. The through hole is used to pass through the connecting rod 112 of the push rod 110, so that the locking part 111 is located in the hollow part of the fixed frame 121 and can move within the fixed frame 121 along the ejection direction of the test paper 300. In order to ensure that the locking part 111 can be stably locked between the first elastic arm 122 and the second elastic arm 123, preferably, the through hole is located at the midpoint of the line connecting the first elastic arm 122 and the second elastic arm 123 in the fixed frame 121.
[0038] like Figure 1 As shown, a first return spring 130 is sleeved on the outer wall of the connecting rod 112. One end of the first return spring 130 abuts against the fixed frame 121, and the other end abuts against the push end 113. When the test strip 300 abuts against the end of the push end 113, it can push the push rod 110 to move towards the fixed frame 121. At this time, the first return spring 130 is compressed and stores energy. Until the locking part 111 of the push rod 110 is locked between the first elastic arm 122 and the second elastic arm 123, the assembly of the test strip 300 is completed. At this time, the test strip 300 can come into contact with urine, and the urine analyzer 200 can perform analysis and detection. After the test is completed, the first elastic arm 122 and the second elastic arm 123 are driven to move in opposite directions. At this time, the first elastic arm 122 and the second elastic arm 123 are no longer engaged with the locking part 111. At this time, the first return spring 130 releases energy and drives the push rod 110 to return to its original position. The push rod 110 converts the return force of the first return spring 130 into an ejection force on the test paper 300, ejecting the tested test paper 300 along the return direction of the push rod 110.
[0039] With the aforementioned test strip ejection device 100, the operator does not need to touch the test strip 300 after the test is completed, reducing the risk of infection caused by contact with urine; at the same time, the test strip ejection device 100 reduces the number of times the operator manually picks up and puts the test strip, improving the testing efficiency of a large number of samples.
[0040] For example, such as Figure 2 As shown, the free end of the first elastic arm 122 is provided with a first hook lock portion 124 extending inward, and the free end of the second elastic arm 123 is provided with a second hook lock portion 125 extending inward. The first hook lock portion 124 and the second hook lock portion 125 are opposite to each other and spaced apart. The first hook lock portion 124 has a first limiting surface 1241 on the side away from the pushing end 113, and the second hook lock portion 125 has a second limiting surface 1251 on the side away from the pushing end 113. When the locking portion 111 is engaged between the first elastic arm 122 and the second elastic arm 123, the first limiting surface 1241 and the second limiting surface 1251 can respectively abut against the end face of the locking portion 111 facing the connecting rod 112.
[0041] Specifically, such as Figure 2 As shown, the free ends of the first elastic arm 122 and the second elastic arm 123 extend inward between the two arms, respectively, to form a first hook-lock portion 124 and a second hook-lock portion 125, forming a hook-like shape. The first hook-lock portion 124 and the second hook-lock portion 125 are opposite to each other and spaced apart, together forming a clamping slot for the locking portion 111 of the push rod 110. When the locking portion 111 moves to this position, the hook-lock portions can lock the locking portion 111 from both sides, preventing it from moving away from the clamping member 120.
[0042] Among them, such as Figure 2 As shown, the hook-locking part has a first limiting surface 1241 on the side opposite to the pushing end 113, and the second hook-locking part 125 has a second limiting surface 1251 on the side opposite to the pushing end 113. When the test strip 300 pushes the push rod 110 toward the clamping member 120, the locking part 111 enters between the first elastic arm 122 and the second elastic arm 123 and is engaged by the first hook-locking part 124 and the second hook-locking part 125. The limiting surface and the corresponding end face of the locking part 111 are tightly fitted. At this time, even if the operator stops pushing the test strip 300 toward the push rod 110, the push rod 110 will not immediately return to its original position. Through the setting of the first and second locking hooks, the locking state of the push rod 110 can be maintained, ensuring the reliability of subsequent urine testing.
[0043] Furthermore, such as Figure 2 As shown, the first hook lock portion 124 has a first guide slope 1242 on the side facing the second hook lock portion 125, and the second hook lock portion 125 has a second guide slope 1252 on the side facing the first hook lock portion 124; the locking portion 111 has a first embedding slope 1111 corresponding to the first guide slope 1242, and a second embedding slope 1112 corresponding to the second guide slope 1252.
[0044] Specifically, such as Figure 2 As shown, the inner sides of the first hook lock portion 124 and the second hook lock portion 125 are inclined surfaces. The side of the first hook lock portion 124 facing the second hook lock portion 125 has a first guide slope 1242, and the side of the second hook lock portion 125 facing the first hook lock portion 124 has a second guide slope 1252. In one specific embodiment of this application, the relative distance between the first guide slope 1242 and the second guide slope 1252 gradually increases along the ejection direction of the push rod 110. Correspondingly, the relative distance between the first embedding slope 1111 and the second embedding slope 1112 of the locking portion 111 gradually increases along the ejection direction of the push rod 110, so as to ensure that the inclination angles of the first guide slope 1242 and the first embedding slope 1111 correspond, and the angles of the second guide slope 1252 and the second embedding slope 1112 correspond.
[0045] This configuration guides the movement path of the locking part 111. Simultaneously, as the locking part 111 moves towards the clamping member 120 to create relative movement with the first hook lock part 124 and the second hook lock part 125, the relative distance between the first embedding inclined surface 1111 and the second embedding inclined surface 1112 gradually increases along their insertion direction, while the relative distance between the first guide inclined surface 1242 and the second guide inclined surface 1252 gradually decreases along the insertion direction of the locking part 111. This allows the first elastic arm 122 and the second elastic arm 123 to move in opposite directions under the force of the locking part 111, enabling the locking part to engage more quickly between the first elastic arm 122 and the second elastic arm 123. Until the locking part is fully engaged between the first elastic arm 122 and the second elastic arm 123, its ends can abut against the first limiting surface 1241 and the second limiting surface 1251 respectively, improving the reliability of the engagement between the push rod 110 and the clamping member 120.
[0046] In one possible implementation of this application, such as Figure 3 As shown, the test strip ejection device 100 also includes a pressing part 140 disposed between the first elastic arm 122 and the second elastic arm 123; driving the pressing part 140 to move toward the mounting surface can drive the first elastic arm 122 and the second elastic arm 123 to move in opposite directions, and the first reset spring 130 releases energy and drives the push rod 110 to move away from the clamping member 120.
[0047] Specifically, in order to quickly move the first elastic arm 122 and the second elastic arm 123 in a mutually opposing manner, thereby achieving the ejection of the test paper 300, as follows: Figure 3 As shown, a push-button 140 is also provided between the first elastic arm 122 and the second elastic arm 123. The push-button 140 is installed in the middle region of the first elastic arm 122 and the second elastic arm 123, and can directly contact the inner walls of the first elastic arm 122 and the second elastic arm 123. When it is necessary to unlock the locking part 111 to eject the test paper 300, the push-button 140 is driven towards the mounting plane by the operator pressing or other external force, thereby causing the first elastic arm 122 and the second elastic arm 123 to be subjected to an outward driving force.
[0048] Furthermore, such as Figure 2 As shown, optionally, the inner side of the first elastic arm 122 is provided with a first pressing slope 1221 corresponding to the pressing part 140, and the inner side of the second elastic arm 123 is provided with a second pressing slope 1231 corresponding to the pressing part 140. The pressing part 140 is driven to move toward the mounting surface, and the side wall of the pressing part 140 can abut against the first pressing slope 1221 and the second pressing slope 1231 respectively.
[0049] Specifically, such as Figure 2As shown, the relative distance between the first pressing slope 1221 and the second pressing slope 1231 gradually decreases along the movement direction of the pressing part 140 toward the mounting plane. That is, as the pressing part 140 moves toward the mounting plane, its sidewalls gradually come into contact with the first pressing slope 1221 and the second pressing slope 1231. With the inclination of the first pressing slope 1221 and the second pressing slope 1231, the downward force is converted into a driving force that causes the first elastic arm 122 and the second elastic arm 123 to move in opposite directions, allowing the clamping member 120 to quickly unlock the locking part 111 and reset the push rod 110. This design allows the operator to eject the test strip 300 with only a small pressing force, reducing operator fatigue and improving detection efficiency.
[0050] Optionally, such as Figure 3 As shown, a second return spring 141 is provided between the push part 140 and the mounting surface. One end of the second return spring 141 abuts against the push part 140 and the other end abuts against the mounting surface. The second return spring 141 is used to provide a return force to the push part 140.
[0051] Specifically, when the push button 140 is not pressed, the second return spring 141 is in a free state. When the operator presses down the push button 140, the second return spring 141 is driven and stores energy; when the pressure disappears, the second return spring 141 releases energy and drives the push button 140 to reset. At this time, the first elastic arm 122 and the second elastic arm 123 are no longer driven by outward force and reset together, preparing for the next locking of the locking part 111 of the locking push rod 110.
[0052] In another aspect of the embodiments of this application, a urine analyzer 200 is provided, such as... Figure 4 and Figure 5 As shown, the device includes a housing 210 and a test strip ejection device 100. The housing 210 has a cavity for housing the test strip ejection device 100 and the test strip 300. An opening 213 is provided at the end of the housing 210 along the ejection direction of the test strip 300. The test strip 300 extends into the cavity through the opening 213 and abuts against the pushing end 113 of the test strip ejection device 100. The housing 210 also has a detection part for detecting data in the area where the test strip 300 comes into contact with urine. After data detection, the test strip 300 is ejected by the test strip ejection device 100 through the opening 213.
[0053] Specifically, such as Figure 4 and Figure 5As shown, the housing 210 includes a first housing 211 and a second housing 212 that are detachably connected. The first housing 211 has a first cavity for setting the test strip ejection device 100, and the second housing 212 has a second cavity for setting the test strip 300. The first cavity and the second cavity are connected so that the push rod 110 of the test strip ejection device 100 can abut against the end of the test strip 300.
[0054] like Figure 5 As shown, the second housing 212 has an opening 213 at its end furthest from the first housing 211. This opening 213 serves as the inlet and outlet for the test strip 300, ensuring that the test strip 300 is inserted into the cavity along the ejection direction and preventing tilting. After insertion, the test strip 300 abuts against the pushing end 113 of the test strip ejection device 100. To further improve detection safety and convenience, such as... Figure 4 and Figure 5 As shown, the length of the test strip 300 is greater than the length of the second housing 212. That is, when the test strip 300 comes into contact with the pushing end 113 of the test strip ejection device 100, the end of the test strip 300 that is away from the test strip ejection device 100 extends out from the opening 213 to facilitate contact with urine.
[0055] In this way, the test strip 300 can come into contact with urine only after being placed in the urine analyzer 200, further reducing the possibility of the operator coming into contact with urine during the installation or removal of the test strip 300, and improving the convenience and safety of operation.
[0056] The second housing 212 also houses a detection unit. In one embodiment of this application, the detection unit includes a light source, such as an LED, capable of emitting detection light of a specific wavelength. The detection light illuminates the reaction reagent coating of the test strip 300, and the reaction reagent coating undergoes a color change reaction upon contact with urine. The detection light is reflected by the test strip 300 to form reflected light containing shoelace color information. This reflected light is received by a color sensor, which converts the light information into spectral data and transmits it to a data processing unit. The data processing unit analyzes the spectral data, such as color depth and wavelength changes, using algorithms to calculate the values of various physiological indicators. The values of these physiological indicators can be output through a display screen or printer connected to the urine analyzer 200.
[0057] In existing technologies, operator errors may cause the test strip to fail to be placed in the preset position of the detection slot, resulting in insufficient contact with the detection instrument and reduced reliability of the test results. However, this application only requires the test strip 300 to abut against the push end 113 through the opening 213 of the housing 210, locking the push rod 110 with the clamping member 120. This ensures that the optical detection unit within the second housing 212 can detect the test strip 300, improving operational convenience and detection efficiency.
[0058] like Figure 5As shown, the top surface of the first housing 211 has a through hole corresponding to the clamping member 120 of the test strip ejection device 100. The through hole is used to pass through the button 216, which is located between the first elastic arm 122 and the second elastic arm 123 of the clamping member 120. The operator can drive the button 216 to move towards the bottom surface of the first cavity, thereby driving the first elastic arm 122 and the second elastic arm 123 to move in opposite directions. At this time, the clamping member 120 and the locking part 111 of the push rod 110 are unlocked, and the push rod 110 can eject the test strip 300. After the urine test is completed, the operator can press the button 216 to make the test strip ejection device 100 eject the test strip 300 from the opening 213. The specific structure and beneficial effects of the paper ejection device have been described in detail above and will not be repeated here.
[0059] The urine analyzer 200 described above, through the setting of the test strip ejection device 100, can effectively reduce the possibility of operators coming into contact with urine and improve operational safety; at the same time, it is easy to operate and improves work efficiency.
[0060] Optionally, such as Figure 6 As shown, to improve the accuracy of the ejection direction of the test strip 300, a guide groove 214 is provided between the second cavity and the first cavity along the ejection direction of the test strip 300, and the first cavity and the second cavity are connected through the guide groove 214; the pushing end 113 of the test strip ejection device 100 passes through the guide groove 214. In a specific embodiment of this application, a 2.0 mm gap is left between the inner wall of the guide groove 214 and the outer wall of the pushing end 113 to limit the movement of the pushing end 113, ensuring that the pushing end 113 can move in a straight line, thereby improving the stability and accuracy of the ejection of the test strip 300.
[0061] Optionally, such as Figure 4 As shown, a limiting plate 215 is provided in the first cavity, and the limiting plate 215 is perpendicular to the ejection direction of the test paper 300; the clamping member 120 of the test paper ejection device 100 abuts against the limiting plate 215 on the side facing the push end 113. It should be noted that this application does not impose any limitation on the specific number of limiting plates 215, as long as they can fix the position of the clamping member 120 and prevent the clamping member 120 from moving due to the movement of the push rod 110, while not interfering with the movement of the push rod 110.
[0062] In a preferred embodiment of this application, such as Figure 4 As shown, there are two limiting plates 215. The two limiting plates 215 are spaced apart on the opposite inner walls of the first cavity and are perpendicularly connected to the inner walls respectively, so as to simultaneously limit the left and right sides of the clamping member 120, further improving the setting stability of the clamping member 120.
[0063] The specific steps for using the urine analyzer 200 provided in this application are as follows:
[0064] First, the operator inserts the dry test strip 300 into the cavity inside the housing 210 through the opening 213, so that the end of the test strip 300 abuts against the pushing end 113 of the paper ejection device. As the test strip 300 is inserted, the push rod 110 of the paper ejection device is driven to move toward the clamping member 120 until the locking part 111 of the push rod 110 is clamped between the first elastic arm 122 and the second elastic arm 123, thus completing the installation of the test strip 300.
[0065] After the test strip 300 is installed, the end of the test strip 300 facing away from the paper ejector extends from the opening 213 to the outside of the urine analyzer 200, facilitating contact with urine. The urine can gradually spread from one end of the test strip 300 to the reaction reagent coating of the test strip 300, and a color change reaction occurs.
[0066] The optical detection unit inside the housing 210 can detect the values of various physiological indicators in the urine based on the color change reaction between the test strip 300 and the urine. The values of the physiological indicators can be output through a display screen or printer connected to the urine analyzer 200.
[0067] After the test is completed, the operator presses button 216 on the housing 210 to move the first elastic arm 122 and the second elastic arm 123 in opposite directions, thereby unlocking the locking part 111 of the push rod 110. The push rod 110 quickly resets under the drive of the first reset spring 130 and converts the reset force provided by the first reset spring 130 into an ejection force on the test strip 300, ejecting the test strip 300 from the opening 213 into the urine analyzer 200.
[0068] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0069] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
