Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sample feeding tray for a plasma electrolyte detector. Background Technology

[0002] A plasma electrolyte analyzer is an important clinical testing instrument primarily used to measure the concentration of electrolytes such as potassium, sodium, chloride, calcium, and lithium ions in blood plasma. These electrolytes play a crucial role in maintaining normal physiological functions, and changes in their concentrations can reflect a person's health status. In practice, blood samples are typically collected in test tubes and then transferred to the analyzer for testing. Proper placement of the test tubes is essential to ensure the samples are not contaminated or affected by external interference; they must be clean, sealed, and placed securely on a stable platform for subsequent operations.

[0003] Typically, these devices are equipped with multiple tube slots to secure the tubes and prevent them from tipping over or rolling. However, these slots may not fit when the tube size changes slightly, leading to unstable placement. A major drawback of existing plasma electrolyte analyzers and related sample trays is the issue of tube compatibility and size consistency. Because different brands and specifications of tubes vary in diameter, length, and capacity, existing sample trays cannot fully accommodate all types of tubes, causing them to easily loosen or slip during placement and removal.

[0004] Another significant drawback is that existing detectors typically require a certain level of liquid in the test tube during the detection process. This is because different detection methods require different sample volumes, and the liquid level in the test tube directly affects the contact area between the ion-selective electrode and the sample, as well as the reaction time. Furthermore, when data detection errors occur, the equipment error needs to be avoided through multiple tests, necessitating the division of the sample into multiple portions. Maintaining the correct liquid level in the test tubes also requires smaller diameter tubes. Utility Model Content

[0005] To overcome the drawback of low compatibility, this invention provides a high-compatibility sample tray for a plasma electrolyte analyzer.

[0006] A sample tray for a plasma electrolyte analyzer includes a base, a plasma electrolyte analyzer, and a sample tray. The plasma electrolyte analyzer is placed on the base, and the sample tray is placed on the base. A drive disk is installed inside the sample tray, and a clamping assembly for placing test tubes is provided on the drive disk. A first rack is slidably connected inside the sample tray, and a top rod is connected to the top of the first rack. The top rod passes through the drive disk and contacts the clamping assembly. A gear is rotatably connected inside the sample tray. A pressure plate is slidably connected to the outer ring of the sample tray. A second rack is connected to the inner portion of the pressure plate inside the sample tray. The first rack and the second rack are located on both sides of the gear and mesh with the gear. A second return spring is provided between the second rack and the sample tray.

[0007] As an improvement to the above solution, the clamping assembly includes a base plate, with multiple base plates connected to the outer ring of the drive disk, and multiple fixing plates connected around the base plate. A guide rod is slidably connected to the fixing plate, and a clamping plate is connected to the guide rod in the direction toward the center of the base plate. A first return spring is sleeved on the guide rod, with one end of the first return spring connected to the fixing plate and the other end connected to the clamping plate.

[0008] As an improvement to the above solution, a sponge pad is connected to the side of the clamping plate facing the center of the base plate.

[0009] As an improvement to the above solution, a collection box is placed on the base.

[0010] As an improvement to the above solution, a dustproof bag is provided at the sliding connection between the pressure plate and the material tray.

[0011] As an improvement to the above solution, multiple guide rods are connected to the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The clamping assembly uses the clamping plate, guide rod and first reset spring to stably clamp the plasma sample tube. The spring's elastic force automatically adapts to tubes of different sizes, improving the compatibility and flexibility of the clamping.

[0014] 2. Through gears, a first rack, a push rod, and a second rack, the second rack descends and, after passing through the gear transmission, the first rack rises and pushes the push rod to lift the test tube from the bottom, thus enabling easy removal of the test tube, optimizing the testing process, and improving testing efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: A sample feeding tray for a plasma electrolyte analyzer, such as... Figures 1-3 As shown, the device includes a base 1, a plasma electrolyte analyzer 101, a tray 102, a drive plate 103, a clamping assembly 2, a gear 3, a first rack 4, a push rod 5, a second rack 6, a pressure plate 7, and a second return spring 8. The plasma electrolyte analyzer 101 is placed on the base 1, and the tray 102 is also placed on the base 1. The drive plate 103 is installed inside the tray 102, and the drive plate 103 is equipped with a clamping assembly 2 for placing test tubes. The first rack 4 is slidably connected inside the tray 102, and the top of the first rack 4 is fixed. A push rod 5 is connected, which passes through the drive plate 103 and contacts the clamping assembly 2. A gear 3 is rotatably connected inside the material tray 102. A pressure plate 7 is slidably connected to the outer ring of the material tray 102. A second rack 6 is fixedly connected to the part of the pressure plate 7 located inside the material tray 102. The first rack 4 and the second rack 6 are located on both sides of the gear 3 and are both meshed with the gear 3. A second return spring 8 is provided between the second rack 6 and the material tray 102. The top of the second return spring 8 is fixedly connected to the second rack 6, and the bottom is fixedly connected to the material tray 102.

[0021] like Figure 2 and Figure 3As shown, the clamping assembly 2 includes a base plate 201, a fixing plate 202, a guide rod 203, a first reset spring 204, and a clamping plate 205. Multiple base plates 201 are fixedly connected to the outer ring of the drive disk 103. Multiple fixing plates 202 are connected around the base plate 201. A guide rod 203 is slidably connected to the fixing plate 202. A clamping plate 205 is fixedly connected to the guide rod 203 in the direction of the center of the base plate 201. A first reset spring 204 is sleeved on the guide rod 203. One end of the first reset spring 204 is fixedly connected to the fixing plate 202, and the other end is fixedly connected to the clamping plate 205.

[0022] At the start of the testing process, the operator inserts the plasma sample tube to be tested into the clamping assembly 2 on the tray 102. During this process, the tube is guided into the space formed by four clamping plates 205. As the tube is inserted, the guide rod 203 and the connected clamping plates 205 are pushed, causing the first return spring 204 to be compressed. The compression force of the spring causes the clamping plates 205 to press tightly against and hold the tube, ensuring its stability during the testing process and avoiding testing errors caused by shaking or falling off. At this time, the tube has been securely placed in the designated position on the drive plate 103, ready for subsequent automated testing steps. When the plasma electrolyte analyzer 101 is ready and begins to test the sample, the drive plate 103 starts and rotates, driving the base plate 201 and the tubes mounted on the base plate 201 to move sequentially to the testing area of ​​the analyzer. During this process, each tube is stably clamped by the clamping assembly 2, ensuring safety and accuracy during rotation.

[0023] After the test is completed, for smaller test tubes, manual removal may be difficult. In this case, the test tube can be lifted by operating the pressure plate 7. Specifically, pushing the pressure plate 7 downwards will cause the connected second rack 6 to descend, compressing the second return spring 8. The gear 3, which meshes with the second rack 6, will rotate. Since gear 3 is simultaneously meshed with the first rack 4, and the first rack 4 and the second rack 6 are located on opposite sides of gear 3, the rotation of gear 3 will cause the first rack 4 and the second rack 6 to move in opposite directions. The lifting mechanism drives the push rod 5 upward until it passes through the opening of the drive plate 103, contacts the bottom of the test tube, and applies an upward force. This force applied from the bottom effectively pushes the test tube out of the clamping assembly 2, optimizing the test tube removal process. After the test tube is removed, the pressure on the pressure plate 7 is released. The second return spring 8, relying on its rebound force, pushes the second rack 6 and the pressure plate 7 back to the initial position. At the same time, the gear 3 also automatically resets under the action of the second rack 6, and the first rack 4 and the push rod 5 also reset accordingly, preparing for the next test tube release operation.

[0024] like Figure 2 and Figure 3As shown, it also includes a sponge pad 9, and the sponge pad 9 is connected to the side of the clamping plate 205 facing the center of the base plate 201.

[0025] The addition of the sponge pad 9 not only increases the friction between the test tube and the clamp 205, improving the stability of the clamping, but also reduces scratches or damage to the test tube caused by direct friction.

[0026] like Figure 1 As shown, it also includes a collection box 10, which is placed on the base 1.

[0027] The inclusion of collection box 10 provides a convenient storage space for waste that may be generated during the testing process, keeping the working environment clean.

[0028] like Figure 1 As shown, it also includes a dust bag 11, which is provided at the sliding connection between the pressure plate 7 and the material tray 102.

[0029] The dust bag 11 effectively prevents dust or foreign objects from entering the interior of the tray 102 through the connection between the pressure plate 7 and the tray 102, protecting the cleanliness of the internal components and ensuring their normal function.

[0030] like Figure 1 As shown, it also includes guide rods 12. Multiple guide rods 12 are connected to the base plate 201, and the distance between the guide rods 12 is greater than the distance between the clamping plates 205.

[0031] The guide rod 12 further simplifies the operation of the test tube insertion clamp assembly 2, making the entire testing process smoother and more efficient.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
