[0002] In the pre-test processing stage of medical test samples, due to the characteristics of the samples, one or more diluents or reagents basically need to be added and mixed to facilitate the test. A sample adding and diluting device is an automated laboratory device used to accurately dispense and dilute liquid samples. This device is especially used in occasions where precise control of sample concentration is required in experiments. The operator only needs to input the required sample concentration and total amount, and the sample adding and diluting device will automatically calculate the amount of the original sample and diluent required and complete the entire dilution process.
[0003] When the existing sample adding and diluting device is used for medical test sample adding, the reagent liquid in the sample storage box is sucked into the sample tray through a sampling needle. Since a single sampling needle is shared, when sampling and preparing standards for multiple liquids in batches, after the sampling needle penetrates into the sample tray, the liquid remaining on the outer wall is likely to be mixed with the reagent in the box, resulting in contamination of the reagent in the sample storage box and affecting the detection accuracy. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a medical testing sample adding and diluting device, which controls the leakage of the sample storage box by the movement of the sampling needle, and at the same time allows the reagent liquid to flow into the sampling pool for the sampling needle to suck, so as to prevent the sampling needle from directly penetrating into the sample storage box, avoid the mixing of the liquid remaining on the sampling needle and the reagent in the sample storage box, keep the reagent in the sample storage box pure, and reduce the influence on the detection accuracy.
[0005] The technical solution adopted by the utility model is specifically as follows:

One end of the support rod is elastically connected with the liquid storage pool through a bending spring.
[0007] A sampling needle is slidably assembled on one side of the sliding arm. A sleeve is fixedly sleeved on the outer wall of the sampling needle.
[0008] The outer wall of the casing is fixedly connected with side plates, and one side of the side plates is fixedly connected with pressing rods.
[0009] Clamping plates are symmetrically arranged at the top of one end of the sampling pool protruding from the liquid storage pool.
[0010] The outer wall of the sampling pool is fixedly connected with snap buttons, and the clamping plates are movably fitted with the snap buttons through the inlaid plates at both ends.

[0022] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.
[0023] As Figures 1-6 shown, a medical test sampling diluter includes a slide arm 101 slidably assembled on the top of the sampling diluter 1. A sampling needle 108 is slidably assembled on one side of the slide arm 101. A sheath 102 is fixedly sleeved on the outer wall of the sampling needle 108. A side plate 109 is fixedly connected to the outer wall of the sheath 102. A pressing rod 110 is fixedly connected to one side of the side plate 109. A sample storage box 103 is fixedly assembled on one side of the sampling diluter 1. A liquid storage pool 104 is fixedly connected to the bottom of the sample storage box 103. A sampling pool 111 is fixedly connected to the bottom of the liquid storage pool 104. The sampling pool 111 is set as an L-shaped with one end protruding from the liquid storage pool 104. The liquid storage pool 104 is set as circular. A leakage port 118 is penetratingly opened at one end of the interior of the liquid storage pool 104 intersecting with the sample storage box 103. A liquid outlet 121 is fixedly connected to the bottom of the liquid storage pool 104 and at the top of the sampling pool 111. A rotating rod 105 is rotatably connected to the middle of the liquid storage pool 104. A rotating plate 119 is fixedly connected to the outer wall of the rotating rod 105 and inside the liquid storage pool 104. A sealing plate 120 for opening and closing the leakage port 118 is fixedly connected to one end of the rotating plate 119. A support rod 106 is fixedly connected to one end of the rotating rod 105 and outside the liquid storage pool 104. One end of the support rod 106 is elastically connected to the liquid storage pool 104 through a bending spring 107.
[0024] According to the above structure, the sliding arm 101 drives the sleeve 102 and the sampling needle 108 to move. When the sampling needle 108 slides downward and penetrates into the sampling pool 111 for sampling, it drives the sleeve 102 to move. The sleeve 102 drives the side plate 109 and the pressure rod 110 to move downward. The pressure rod 110 presses down the support rod 106 to make it rotate. The support rod 106 drives the rotating rod 105 to rotate. In the initial state, the rotating plate 119 is in an inclined position, and the sealing plate 120 does not close the liquid leakage port 118. One end of the rotating plate 119 is located on one side of the liquid outlet 121, so that the liquid inside the sample storage box 103 can flow through the liquid leakage port 118 and be temporarily stored in the liquid storage pool 104. When the rotating rod 105 rotates to drive the rotating plate 119 to rotate, the sealing plate 120 closes the liquid leakage port 118 to prevent the liquid in the sample storage box 103 from leaking downward. At the same time, one end of the rotating plate 119 rotates to the side of the liquid outlet 121 and leaks out of the liquid outlet 121. The liquid previously stored in the liquid storage pool 104 can then flow into the sampling pool 111 through the liquid outlet 121. Since the sampling pool 111 is set in an L shape, the sampling needle 108 can penetrate into the sampling pool 111 from one side of the liquid storage pool 104. When the sampling needle 108 completes sampling and moves upward, the pressure rod 110 no longer presses the support rod 106, and the bending spring 107 contracts to reset the structures such as the support rod 106, the rotating rod 105, the rotating plate 119, and the sealing plate 120.
[0025] Refer to the attached Figures 3-5 At one end of the sampling pool 111 protruding from the top of the liquid storage pool 104, clamping plates 114 are symmetrically arranged. The outer wall of the sampling pool 111 is fixedly connected with snap buttons 117. The clamping plates 114 are movably fitted with the snap buttons 117 through the embedded plates 116 at both ends. The inner wall of the clamping plates 114 is movably fitted with sponge blocks 113. On one side of the clamping plates 114 and symmetrically on both sides of the sponge blocks 113, convex blocks 112 are fixedly connected. A perforation 115 for the sampling needle 108 to slide and embed is opened on one side of the sponge block 113.
[0026] According to the above structure, when the sampling needle 108 penetrates into the sampling pool 111 for sampling, the perforation 115 provides an opening for it. The sponge block 113 wipes the residual liquid on its outer wall. The convex blocks 112 provide support for the sponge block 113. By sliding the clamping plate 114 to disengage the embedded plate 116 from the snap button 117, the sponge block 113 can be slid out of the clamping plate 114 for replacement. The present utility model controls the liquid leakage of the sample storage box 103 through the movement of the sampling needle 108, and at the same time, the reagent liquid flows into the sampling pool 111 for the sampling needle 108 to suck, thereby preventing the sampling needle 108 from directly penetrating into the sample storage box 103, avoiding the mixing of the liquid remaining on the sampling needle 108 with the reagent in the sample storage box 103, keeping the reagent in the sample storage box 103 pure, and reducing the impact on the detection accuracy.
[0027] The working principle of the present utility model is as follows: The sliding arm 101 drives the sleeve 102 and the sampling needle 108 to move. When the sampling needle 108 slides downward and probes into the sampling pool 111 for sampling, it drives the sleeve 102 to move. The sleeve 102 drives the side plate 109 and the pressing rod 110 to move downward. The pressing rod 110 presses down the support rod 106 to make it rotate. The support rod 106 drives the rotating rod 105 to rotate. In the initial state, the rotating plate 119 is in an inclined position, and the sealing plate 120 does not close the liquid leakage port 118. One end of the rotating plate 119 is located on one side of the liquid outlet 121, so that the liquid inside the sample storage box 103 can flow through the liquid leakage port 118 and be temporarily stored in the liquid storage pool 104. When the rotating rod 105 rotates to drive the rotating plate 119 to rotate, the sealing plate 120 closes the liquid leakage port 118 to prevent the liquid in the sample storage box 103 from leaking downward. At the same time, one end of the rotating plate 119 rotates to the side of the liquid outlet 121 and leaks out of the liquid outlet 121. The liquid previously stored in the liquid storage pool 104 can then flow into the sampling pool 111 through the liquid outlet 121. Since the sampling pool 111 is arranged in an L shape, the sampling needle 108 can probe into the sampling pool 111 from one side of the liquid storage pool 104. When the sampling needle 108 finishes sampling and moves upward, the pressing rod 110 no longer presses the support rod 106, and the bending spring 107 contracts to reset the structures such as the support rod 106, the rotating rod 105, the rotating plate 119, and the sealing plate 120. When the sampling needle 108 probes into the sampling pool 111 for sampling, the perforation 115 provides an opening for it. The sponge block 113 wipes the residual liquid on its outer wall, and the convex block 112 provides support for the sponge block 113. By sliding the clamping plate 114, the embedded plate 116 is disengaged from the buckle 117, and the sponge block 113 can be slid out of the clamping plate 114 and removed for replacement.
[0028] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
