Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a sample feeding device for a plasma analyzer. Background Technology

[0002] Plasma testing is a common procedure in medical laboratories. Through quantitative analysis of various chemical components in plasma, it provides important diagnostic information for clinicians. Plasma testing can be applied to determine the physiological and pathological chemical components of plasma, rapid biochemical tests, blood glucose tests, especially endocrine baseline determination, and examinations for thrombosis and hemostasis.

[0003] A plasma analyzer is a medical device used to detect coagulation function and related components in plasma. When it is working, test tubes containing plasma samples are first placed on the analyzer's platform. Then, a moving arm drives the pipette to move and draw the sample from the test tube. The sample is then dripped onto the detection position for testing, achieving an automatic feeding and detection function. However, after the pipette draws the plasma sample, plasma will also adhere to the outer wall of the pipette. During the pipette's movement, the plasma adhering to the outer wall may drip onto the platform or into other test tubes, causing mixed testing problems. Utility Model Content

[0004] To overcome the drawback that plasma adhering to the outer wall of the pipette may drip onto the table or into other test tubes during pipette movement, causing mixed testing, the technical problem is to provide a sample loading device for a plasma analyzer that can prevent plasma from dripping onto the table or into other test tubes.

[0005] The technical solution is as follows: A sample loading device for a plasma analyzer includes a plasma analyzer, a moving arm, a pipette, an electric slide rail, a movable plate, an L-shaped plate, and a collection box. The plasma analyzer is equipped with a moving arm, on which a pipette is mounted. The moving arm can drive the pipette to move up and down, left and right, and forward and backward. The pipette can draw up the plasma sample from the test tube and drip it onto the detection position. An electric slide rail is installed at the bottom of the moving arm and is electrically connected to the controller of the plasma analyzer. A movable plate is connected to the moving part of the electric slide rail and is slidably connected to the moving arm. The movable plate is located below the pipette and has an opening at the front. L-shaped plates are symmetrically connected to the left and right sides of the bottom front of the movable plate. A collection box is engaged between the two L-shaped plates and is located below the opening. The collection box can collect the plasma dripping from the pipette.

[0006] Preferably, the collection box also includes a tray, a baffle, and an operating plate. A groove is provided on the right side of the collection box, and a tray is slidably connected in the groove. A baffle is connected to the tray and slides through the collection box. The baffle can block the upper part of the collection box. An operating plate is connected to the left side of the baffle and slides through the left side of the collection box.

[0007] Preferably, the collection box also includes an observation window. The observation window is embedded in the front of the collection box and is made of transparent material. The observation window is used to observe the collection situation inside the collection box.

[0008] Preferably, it also includes magnets, with magnets provided on both the tray and the back of the collection box, and the two magnets adsorbing and engaging.

[0009] Preferably, it also includes a flow guide groove, which is provided in the opening of the movable plate and is connected to the movable plate.

[0010] Preferably, the collection box also includes a handle, with a handle attached to the front side of the collection box, making it easy to take out the collection box.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a moving arm to move the pipette. When the pipette needs to draw or drip plasma samples, the electric slide rail can move the movable plate and collection box away from below the pipette without affecting the vertical movement of the pipette. After the pipette moves upward and resets, the electric slide rail will move the movable plate and collection box forward again, so that the collection box is located below the pipette, thereby preventing plasma samples adhering to the outer wall of the pipette from dripping onto the table or other test tubes, which would lead to mixed testing and affect the accuracy of the test data.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example: A sample loading device for a plasma analyzer, such as... Figure 1-4 As shown, the system includes a plasma analyzer 1, a moving arm 101, a pipette 102, an electric slide rail 2, a movable plate 3, an L-shaped plate 4, and a collection box 5. The plasma analyzer 1 is equipped with a moving arm 101, on which the pipette 102 is mounted. The moving arm 101 can move the pipette 102 up and down, left and right, and forward and backward. The pipette 102 can draw plasma samples from the test tube and drip them onto the detection position. An electric slide rail 2 is installed at the bottom of the moving arm 101, and the electric slide rail 2 is electrically connected to the controller of the plasma analyzer 1. A movable plate 3 is connected to the movable part of the track 2. The movable plate 3 is slidably connected to the movable arm 101. The movable plate 3 is located below the straw 102. An opening is provided at the front of the movable plate 3. L-shaped plates 4 are symmetrically connected to the left and right sides of the bottom front of the movable plate 3. A collection box 5 is snapped between the two L-shaped plates 4. The collection box 5 is located below the opening. The collection box 5 can collect the plasma dripping from the straw 102. The electric slide rail 2 drives the collection box 5 to move back and forth through the movable plate 3, so that the collection box 5 is moved directly below the straw 102 or moved away from directly below the straw 102.

[0020] like Figure 2 and Figure 5 As shown, it also includes a tray 7, a baffle 8, an operating plate 9, and a magnet 11. A groove 6 is provided on the right side of the collection box 5, and the tray 7 is slidably connected in the groove 6. The baffle 8 is connected to the tray 7 and slides through the collection box 5. The baffle 8 can block the upper part of the collection box 5. The operating plate 9 is connected to the left side of the baffle 8 and slides through the left side of the collection box 5. Magnets 11 are provided on the tray 7 and the rear side of the collection box 5, and the two magnets 11 are attracted to each other.

[0021] like Figure 2 and Figure 3 As shown, it also includes an observation window 10. The observation window 10 is embedded in the front of the collection box 5. The observation window 10 is made of transparent material and is used to observe the collection situation inside the collection box 5.

[0022] like Figure 1 and Figure 2 As shown, it also includes a flow guide 12. The flow guide 12 is provided in the opening of the movable plate 3 and is connected to the movable plate 3.

[0023] like Figure 1 and Figure 2 As shown, it also includes a handle 13. The front side of the collection box 5 is connected to the handle 13, which makes it convenient to take the collection box 5.

[0024] In use, test tubes containing plasma samples are placed on the platform of the plasma analyzer 1. The baffle 8 is moved backward by the control panel 9, separating the two magnets 11 so that the baffle 8 does not obstruct the upper part of the collection box 5. After starting the plasma analyzer 1, the moving arm 101 moves the pipette 102 and collection box 5 synchronously. When the pipette 102 moves above the test tube from which the sample needs to be drawn, the moving arm 101 stops moving. Simultaneously, the electric slide rail 2 moves the movable plate 3 backward, thereby moving the collection box 5 backward. At this point, the movable plate 3 and collection box 5 move away from directly below the pipette 102. Then, the moving arm 101 moves the pipette 102 downward, allowing it to enter the test tube. The pipette 102 then draws the plasma sample from the test tube. Finally, the moving arm 101 moves the pipette 102 upward. The electric slide rail 2 drives the movable plate 3 to move forward and reset, so that the collection box 5 is located directly below the pipette 102. If the plasma sample attached to the outer wall of the pipette 102 drips down, the collection box 5 can collect the dripping plasma sample, while the guide groove 12 can collect the dripping plasma sample in a concentrated manner and prevent the plasma sample from splashing out when dripping. In this way, the dripping plasma sample can be prevented from dripping onto the table or into other test tubes, which would cause mixed testing and affect the accuracy of the test data. Then, after the moving arm 101 drives the pipette 102 to move to the test position, the electric slide rail 2 drives the movable plate 3 and the collection box 5 to move backward again. The pipette 102 drips the drawn plasma sample onto the inspection position, which can realize automatic feeding and inspection of plasma samples and prevent the plasma sample from dripping and affecting the test data.

[0025] When the pipette 102 moves horizontally, the collection box 5 is located below the pipette 102 and can collect the dripping plasma sample. When the pipette 102 moves vertically, the movable plate 3 moves the collection box 5 away from directly below the pipette 102, so as not to affect the pipette 102's absorption and dripping of the plasma sample.

[0026] When it is necessary to clean the collection box 5, push the baffle 8 forward using the control panel 9. The two magnets 11 attract each other, so that the baffle 8 is stably blocked on the upper part of the collection box 5. Then, use the handle 13 to remove the collection box 5 from between the two L-shaped plates 4. The baffle 8 can prevent the plasma sample inside from dripping out when the collection box 5 is removed. Then clean the collection box 5. After cleaning, the collection box 5 can be locked onto the two L-shaped plates 4.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
