[0041] See also Figure 1 and Figure 2 , a specimen retention box provided by an embodiment of the present invention includes a box body 100 and a release component 200. The box body 100 can contain a liquid to be tested, such as urine. The release component 200 is arranged inside the box body 100, and the release component 200 can release a reagent into the box body 100. The reagent can be a preservative or other reagents.

[0042] During the process of retaining the liquid to be tested, the liquid to be tested is located in the box body 100, and the release assembly 200 releases the reagent into the box body 100. Compared with the method of opening the box body 100 to place the reagent, the solution shown in this application is more convenient and reduces the time and number of times the liquid to be tested is exposed to the air.

[0043] In a possible embodiment of the present invention, the box body 100 may be a columnar box body 100, such as a quasi-cylindrical box body, a quasi-cuboid box body, etc. The box body 100 has a top surface 101 and a bottom surface 102, and the direction from the top surface 101 to the bottom surface 102 of the box body 100 is the height direction of the box body 100.

[0044] The box body 100 has a liquid inlet 103 and a liquid outlet 104. The liquid inlet 103 of the box body 100 is located on the top surface 101 of the box body 100, and the liquid outlet 104 of the box body 100 is located on the bottom surface 102 of the box body 100 or close to the bottom surface 102 of the box body 100. In some embodiments, the liquid outlet 104 is located on the side wall close to the bottom surface 102 of the box body 100.

[0045] A flow guide 300 is provided at the liquid inlet 103 of the box body 100. The flow guide 300 and the box body 100 can be integrally formed, or they can be assembled into one piece after being formed separately, or they can be connected in other ways. The flow guide 300 has a flow guide slope 301, and the flow guide slope 301 gradually approaches the middle of the liquid inlet 103 along the direction from the bottom surface 102 to the top surface 101 of the box body 100. In some embodiments, the flow guide slope 301 is a conical surface, and the conical cross section gradually increases along the direction from the bottom surface 102 to the top surface 101 of the box body 100. When the liquid to be tested is injected, the liquid can flow to the liquid inlet 103 through the flow guide slope 301 of the flow guide 300, and flow into the box body 100.

[0046] A cover plate 400 is provided at the liquid inlet 103 of the box body 100, and the cover plate 400 can be opened and closed relative to the liquid inlet 103. In some embodiments, one side of the cover plate 400 is hinged to the inner wall of the box body 100. When the cover plate 400 is located in the first position, the cover plate 400 contacts the box body 100, and the cover plate 400 isolates the box body 100 from the outside. When the cover plate 400 is located in the second position, the cover plate 400 is separated from the liquid inlet 103, and the cover plate 400 is located inside the box body 100, and the box body 100 is connected to the outside, and the liquid to be tested can be injected into the box body 100 at this time.

[0047] In this embodiment, the box body 100 is provided with an elastic member 500. The elastic member 500 can be a spring or other elastic structure. One end of the elastic member 500 is connected to the box body 100, and the other end of the elastic member 500 is connected to the cover plate 400. When the elastic member 500 is in the original position, the cover plate 400 is in the first position, and the cover plate 400 is in conflict with the liquid inlet 103. When the elastic member 500 is in the deformed position, the cover plate 400 is in the second position, and the cover plate 400 is separated from the liquid inlet 103.

[0048] Specifically, the box body 100 is provided with a connecting strip 110. The length of the connecting strip 110 is greater than or equal to the original length of the elastic member 500. For example, in some embodiments, the length of the connecting strip is equal to the original length of the elastic member 500. One end of the connecting strip 110 is connected to the inner wall of the box body 100. The other end of the connecting strip 110 is hinged to the end of the cover plate 400. The cover plate 400 can rotate along the hinge 401 to open and close relative to the liquid inlet 103. The aforementioned one end of the elastic member 500 connected to the cover plate 400 is located between the contact point between the cover plate 400 and the liquid inlet 103 and the hinge 401. The aforementioned other end of the elastic member 500 connected to the box body 100 is located between the connecting strip 110 and the liquid inlet 103. The above arrangement can pull the cover plate 400 when the elastic member 500 returns to its original length, and can also form a receiving space for the elastic member 500 with the connecting strip 110, the inner wall of the box body 100 and the cover plate 400 to reduce direct contact between the elastic member 500 and the liquid to be tested in the box body 100.

[0049] When the liquid to be tested is retained, the cover plate 400 can be opened by external force, that is, a tool is used to push the cover plate 400. The tool can be a rod-like object, and the diameter of the rod-like object is smaller than the liquid inlet 103. The cover plate 400 can rotate along the hinge 401, and the elastic member 500 has elastic deformation, and the elastic deformation increases. When the cover plate 400 is opened, the cover plate 400 is located in the second position, and the elastic member 500 is in the deformed position. At this time, the liquid to be tested can be injected into the box body 100 from the liquid inlet 103. After the injection is completed, the external force is removed, and the elastic member 500 returns to its original length. The elastic member 500 changes from the deformed position to the original position, and drives the cover plate 400 to rotate along the hinge 401 until the cover plate is located in the first position. At this time, the elastic member 500 is in the original position. When the cover plate 400 is in the first position, the cover plate 400 conflicts with the liquid inlet 103 and covers the liquid inlet 103.

[0050] In some other embodiments, the cover plate 400 may also be openably disposed on the outer wall of the box body 100, so that when the cover plate 400 is in the first position, the cover plate 400 abuts against the liquid inlet 103. Or in some other embodiments, when the cover plate 400 is in the first position, the cover plate 400 abuts against the side of the flow guide 300 away from the box body 100.

[0051] The liquid outlet 104 of the box body 100 is provided with a closure member 600. When the closure member 600 is in the open position, the box body 100 is communicated with the outside world. When the closure member 600 is in the closed position, the box body 100 is sealed with the outside world. In some embodiments, the closure member 600 can select a faucet, in other embodiments, the closure member 600 can select other valves, and in other embodiments, the closure member 600 can be a lid, and can be detachably connected with the liquid outlet 104, such as a threaded connection can be selected. In the present embodiment, the liquid outlet 104 of the box body 100 is located at the bottom of the side wall of the box body 100, and the closure member 600 selects a faucet, so as to release the liquid to be measured in the box body 100.

[0052] In one embodiment, the box body 100 is a transparent box body 100. In another embodiment, the box body 100 may be an opaque box body 100 with a transparent area. The above embodiments can facilitate observation of the liquid to be tested inside the box body 100. Figure 1 The outer wall of the box body 100 may be provided with scale lines 140. The scale lines 140 may be printed scale lines 140, raised scale lines 140, or grooved scale lines 140, and may be adjusted according to actual conditions. The scale lines 140 may facilitate the operator to quantitatively retain the liquid to be tested inside the box body 100.

[0053] In one embodiment, if Figure 2 As shown, the release assembly 200 includes a container 210 and a release member 220. The container 210 can contain a reagent. The release member 220 can move relative to the box body 100 to release the reagent in the container 210 into the box body 100.

[0054] The container 210 has a penetration area 211, and the penetration area 211 can be penetrated by the release member 220 to release the reagent in the container 210 to the outside of the container 210. In one embodiment, the penetration area 211 can be a plastic penetration area 211, and in other embodiments, the penetration area 211 can be a penetration area 211 of other easily penetrable materials. In this embodiment, the outer wall of the container 210 is the penetration area 211, that is, the container 210 can be a container capsule, and any part of its outer wall can be pierced by the release member 220 to release the reagent in the container 210.

[0055] The release member 220 includes a tip portion 221 and a suspension portion 222. The tip portion 221 can pass through the penetration area 211. The suspension portion 222 is connected to the tip portion 221, and the suspension portion 222 can move toward the receiving member 210 under the action of buoyancy, so that the tip portion 221 passes through the penetration area 211.

[0056] In one embodiment, the accommodating member 210 is located near the top surface 101 of the box body 100. Specifically, the box body 100 is provided with a supporting member 120, and the supporting member 120 is connected to the inside of the box body 100. The accommodating member 210 is located above the supporting member 120 away from the bottom surface 102 of the box body 100. The supporting member 120 provides a supporting force for the accommodating member 210. The supporting member 120 has a release port 123, and the release port 123 is aligned with the penetration area 211.

[0057] In one embodiment, the support member 120 includes a first plate 121 and a second plate 122. One end of the first plate 121 is connected to the top surface 101 of the box body 100, and the other end of the first plate 121 is connected to the second plate 122. The first plate 121 can be arranged along the height direction of the box body 100. The second plate 122 is used to provide a supporting force for the accommodating member 210, that is, the accommodating member 210 is located above the second plate 122. The second plate 122 can be arranged vertically with the first plate 121. A side of the second plate 122 away from the first plate 121 has a gap with the inner wall of the box body 100 to form a release port 123. In another embodiment, a side of the second plate 122 away from the first plate 121 is connected to the inner wall of the box body 100. The second plate 122 is provided with a release port 123.

[0058] In addition, in one embodiment, the box body 100 is further provided with a limiting member 130. The limiting member 130 is connected to the supporting member 120. The limiting member 130 has a limiting channel 131. The limiting member 130 has a connecting port 132. One end of the limiting channel 131 is connected to the release port 123, and the other end of the limiting channel 131 is connected to the box body 100 through the connecting port 132. The tip portion 221 of the release member 220 is located in the limiting channel 131.

[0059] After the liquid to be tested is injected into the box body 100, as the volume of the liquid to be tested increases, the water level of the liquid to be tested in the limiting channel 131 rises because the limiting channel 131 is connected to the box body 100. In this process, the release member 220 moves toward the receiving member 210 under the action of buoyancy. When the water level of the liquid to be tested reaches a certain height, the release member 220 penetrates the penetration area 211 of the receiving member 210 to release the solvent in the receiving member 210 to the limiting channel 131, and then releases it into the box body 100.

[0060] Specifically, in one embodiment, one end of the limiting member 130 is connected to the release port 123 of the second plate 122. The other end of the limiting member 130 is a free end 133, and the limiting member 130 is arranged along the height direction of the box body 100. There is a gap between the limiting member 130 and the side wall of the box body 100, and the gap is the aforementioned limiting channel 131. There is a gap between the free end 133 of the limiting member 130 and the bottom surface 102 of the box body 100, and the gap is the aforementioned connecting port 132. The tip 221 of the release member 220 is located in the limiting channel 131. In another embodiment, the limiting member 130 has a through hole arranged along the height direction of the box body 100. The through hole is the aforementioned limiting channel 131. The free end 133 of the limiting member 130 close to the bottom surface 102 of the box body 100 has a gap with the bottom surface 102 of the box body 100. The through hole of the free end 133 of the limiting member 130 is the aforementioned communication port 132 . Similarly, the tip portion 221 of the release member 220 is located in the limiting channel 131 .

[0061] In some embodiments, the suspension portion 222 includes a connecting section 223 and a conflicting section 224. The connecting end is connected to the tip portion 221, and the connection method can be one-piece molding or other connection methods. The connecting section 223 is entirely or partially located in the limiting channel 131. The connecting end of the conflicting section 224 is arranged on a side away from the tip portion 221, and the conflicting section 224 has a conflicting end face 225, and the conflicting end face 225 can conflict with the side of the limiting member 130 away from the support member 120. When the conflicting section 224 conflicts with the limiting member 130, the tip portion 221 passes through the penetration area 211.

[0062] The setting of the conflicting section 224 has at least the following functions: first, preventing the release member 220 from being completely located in the limiting channel 131, which is inconvenient for the next use. Second, quantitative release of reagents. That is, by setting the height between the limiting member 130 and the bottom surface 102 of the box body 100, the reagent in the container 210 can be released only when the liquid in the box body 100 is located at a certain specific volume. For example, in some embodiments, when the liquid to be tested in the box body 100 is 250ml, the reagent in the container 210 is released. At this time, the height between the limiting member 130 and the bottom surface 102 of the box body 100 can be set to be equal to the height of the liquid level when the liquid to be tested in the box body 100 is 250ml. When the liquid to be tested in the box body 100 is greater than or equal to 250ml, the conflicting end face 225 conflicts with the limiting member 130, and the tip 221 passes through the penetration area 211 to release the reagent.

[0063] In some embodiments, the area of ​​the conflicting end face 225 is larger than the cross-sectional area of ​​the limiting channel 131, the cross-sectional area of ​​the limiting channel 131 is larger than the cross-sectional area of ​​the connecting section 223, and when the conflicting end face 225 conflicts with the limiting member 130, there is a gap between the limiting member and the limiting channel 131. That is, the height of the communication port 132 along the height direction of the box body 100 is larger than the height of the conflicting section 224. So that the conflicting end face 225 can conflict with the limiting member 130, and the reagent is released more smoothly.

[0064] The top surface 101 of the box body 100 is also provided with a receiving opening 105, and the receiving opening 105 is used to connect the area where the receiving component 210 is stored with the outside, so as to facilitate the replacement of the receiving component 210. A cover 700 is also provided at the receiving opening 105, and the cover 700 can be closed relative to the receiving opening 105. In one embodiment, the cover 700 is threadedly connected to the receiving opening 105 to achieve a detachable connection. In other embodiments, the cover 700 can be hinged, snap-fitted, or other detachably connected to the receiving opening 105.

[0065] In addition, in this embodiment, the box body 100 may also be provided with a handle 800. The handle 800 may be provided on the top surface 101 of the box body 100 to facilitate the movement of the box body 100. The handle 800 may be fixedly connected to the box body 100, or may be rotatably connected to the box body 100. It can be provided as needed. The two ends of the handle 800 are respectively connected to the box body 100, and the middle part of the handle 800 and the box body 100 have a certain gap for the user to grab the handle 800. In some other embodiments, the handle 800 may be connected to the box body 100 at only one end, and the other end may be provided with a ring structure or a rod structure, so that the user can move the box body 100 through the handle 800. In some other embodiments, the handle 800 may also be other structures.

[0066] In the present invention, the liquid to be tested is injected into the liquid inlet 103 along the guiding slope 301 of the guiding member 300 to enter the box body 100. As the amount of the liquid to be tested in the box body 100 increases, the water level in the box body 100 rises to drive the suspension portion 222 of the release member 220 to move. During the movement, the suspension portion 222 gradually approaches the container 210. When the water level in the box body 100 rises to a suitable position where the reagent needs to be released, the contact end face 225 of the contact section 224 of the release member 220 contacts the limiting member 130, and at the same time, the tip portion 221 pierces the penetration area 211 of the container 210. The reagent in the container 210 flows along the limiting channel 131 to the connecting port 132 and flows into the box body 100 to mix with the liquid to be tested in the box body 100.

[0067] By adopting the above solution, when the liquid to be tested is contained in the box body 100, the reagent can be added at the stage of injecting the liquid to be tested, without opening the box body 100 for injecting the reagent by opening the cover twice, which is more convenient to use. In addition, the present application solution can reduce the contact between the liquid to be tested and the air, reduce the oxidation of the substances in the liquid to be tested by the air, and reduce the release of the liquid to be tested into the air.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
