Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sample box for an electrolyte analyzer. Background Technology

[0002] The sample chamber of an electrolyte analyzer is used to hold serum samples. Traditional sample chambers are typically static, with the serum sample remaining stationary within the sample tube. Fibrinogen in the serum sample, upon contact with the tube wall or air, rapidly initiates a coagulation cascade reaction, converting into fibrin and forming a network structure. When the sample is drawn into the detection path through the pump tube, the coagulated fibrin fibers easily adhere to the inner wall of the tube or clog the electrode inlets, leading to poor sample aspiration, detection interruptions, or even instrument malfunction.

[0003] To alleviate sample coagulation issues, some instruments employ pre-added anticoagulants (such as lithium heparin) or use procoagulant tubes to separate serum. However, anticoagulants may interfere with certain electrolyte detections (e.g., lithium ions interfere with sodium ion assays), and serum separated by procoagulant tubes still needs to be tested within a short time, otherwise the risk of coagulation remains. Furthermore, while manually shaking the sample tube can temporarily delay coagulation, it relies on operator experience and cannot guarantee the stability of the shaking frequency and amplitude, making it difficult to meet the needs of automated testing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a sample box for an electrolyte analyzer.

[0005] To address the aforementioned issue of sample coagulation, some instruments employ methods such as pre-adding anticoagulants or using procoagulant tubes to separate serum. However, anticoagulants may interfere with the detection of certain electrolytes, and serum separated using procoagulant tubes still needs to be tested within a short time; otherwise, the risk of coagulation remains. Furthermore, while manually shaking the sample tube can temporarily delay coagulation, it relies on the operator's experience and cannot guarantee the stability of the shaking frequency and amplitude, failing to meet the technical requirements of automated detection. The technical solution adopted in this invention is: An electrolyte analyzer sample box includes a sample box and a sample rack; A heating component is used to heat the internal environment of the sample box; The heating component includes: A heating chamber and an electric heating wire disposed inside the heating chamber, the heating chamber being located inside the sample box; An oscillation component is used to drive the sample holder to oscillate; The oscillation component includes: The mounting platform is fixedly connected to the sample rack and is used to drive the sample rack to oscillate back and forth. A slide rail and a slide block are slidably connected to the upper end of the slide rail. The slide rail is located at the bottom of the sample box and is used to limit the sliding movement of the installation platform. The transmission mechanism is connected to the mounting platform and is used to drive the mounting platform to move back and forth.

[0006] Preferably, the sample box includes a cover hinged to the upper part of the sample box, wherein an observation window is fixed through the middle of the cover and the observation window is made of transparent material.

[0007] Preferably, the heating chamber is located on the lower inner wall of the sample box, the electric heating wire is supported and fixed inside the heating chamber, and a temperature sensor for temperature control in conjunction with the electric heating wire is fixedly installed inside the sample box.

[0008] Preferably, there are two slide rails, which are horizontally supported and fixed at the bottom of the sample box, the mounting platform is fixed at the upper end of the slide, and the sample rack is fixed at the upper end of the mounting platform.

[0009] Preferably, the transmission mechanism includes a motor, a connecting rod, and a transmission rod. A transmission disk is fixedly mounted on the upper transmission shaft of the motor. The connecting rod is rotatably connected to the upper end of the transmission disk via a pin. The transmission rod is rotatably connected to the end of the connecting rod away from the transmission disk via a pin.

[0010] Preferably, the outer side of the transmission rod is slidably connected to a sliding groove, the sliding groove is horizontally supported and fixedly installed at the bottom of the sample box, and the side of the transmission rod away from the connecting rod is supported and fixedly installed at the lower end of the installation platform.

[0011] Preferably, the sample box has an installation groove at its inner bottom side, the motor is fixedly installed inside the installation groove, and the bottom of the installation groove has heat dissipation holes for heat dissipation of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention controls the activation of the electric heating wire, which, in conjunction with a temperature sensor, precisely heats the interior of the sample chamber, simulating the human body temperature environment, effectively inhibiting coagulation reactions and maintaining ion activity. This invention also controls the start-up motor, which drives the transmission disc to rotate, thereby causing the connecting rod to rotate along the upper end of the transmission disc. This rotational motion then drives the transmission rod to reciprocate linearly along the slide groove, ultimately driving the sample holder to reciprocate linearly via the mounting platform. In this way, the sample tubes inside the sample holder undergo reciprocating oscillation. This continuous shaking of the sample tubes disrupts the polymerization process of blood fibrin monomers, further delaying clotting time and providing more accurate and reliable data support for electrolyte analysis.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] Please see Figure 1 - Figure 4 This embodiment proposes a sample box for an electrolyte analyzer, including a sample box 1, a sample rack 9, and a cover 2. The cover 2 is hinged to the upper end of the sample box 1, providing effective shielding and protection for the sample box 1. An observation window 3, made of transparent material, is glued through the middle of the cover 2, allowing the user to clearly observe the internal condition of the sample box 1, facilitating real-time monitoring and operation.

[0018] A heating chamber 4 is formed in the lower inner wall of the sample chamber 1. Heating wires 5 are supported and fixedly installed on the inner side of the heating chamber 4, providing necessary heating for the interior of the sample chamber 1. Simultaneously, a temperature sensor is also fixedly installed inside the sample chamber 1. Through the close cooperation between the heating wires 5 and the temperature sensor, the temperature inside the sample chamber 1 can be precisely controlled, thereby simulating the human body temperature environment, effectively inhibiting coagulation reactions, and maintaining ion activity.

[0019] Two slide rails 6 are fixedly installed at the bottom inner side of the sample box 1, and these two slide rails 6 are horizontally symmetrically distributed at the bottom inner side of the sample box 1. The upper end of the slide rail 6 is slidably connected to the slide base 7, and the upper end of the slide base 7 is fixedly installed to the mounting platform 8. The sample rack 9 is fixedly installed on the upper end of the mounting platform 8. In addition, a mounting groove 10 is opened at the inner bottom side of the sample box 1. The motor 11 is fixedly installed inside the mounting groove 10. In order to ensure the normal operation of the motor 11, heat dissipation holes are also opened at the bottom of the mounting groove 10 to dissipate heat from the motor 11 in a timely manner. The upper drive shaft of the motor 11 is fixedly installed to the transmission disk 12. The upper end of the transmission disk 12 is rotatably connected to the connecting rod 13 through a pin. The side of the connecting rod 13 away from the transmission disk 12 is rotatably connected to the transmission rod 14 through a pin. The outer side of the transmission rod 14 is slidably connected to the slide groove 15. The slide groove 15 is horizontally supported and fixedly installed at the bottom inner side of the sample box 1, providing effective limit for the horizontal movement of the transmission rod 14. The end of the transmission rod 14 away from the connecting rod 13 is supported and fixed to the lower end of the mounting platform 8, thus achieving a stable connection of the entire transmission system.

[0020] Please continue reading. Figure 1 - Figure 4 In practical use, the sample tube is placed on the sample holder 9 by opening the cover 2. Then, by controlling the activation of the heating wire 5, the heating wire 5, in conjunction with the temperature sensor, precisely heats the inside of the sample chamber 1, simulating the human body temperature environment, effectively inhibiting coagulation and maintaining ion activity. Simultaneously, by controlling the activation of the motor 11, the motor 11 drives the transmission disk 12 to rotate, which in turn drives the connecting rod 13 to rotate along the upper end of the transmission disk 12. This rotational movement drives the transmission rod 14 to reciprocate linearly along the slide groove 15, ultimately driving the sample holder 9 to reciprocate linearly via the mounting platform 8. In this way, the sample tube inside the sample holder 9 undergoes reciprocating oscillation. The continuous shaking of the sample tube disrupts the polymerization process of blood fibrin monomers, thereby further delaying coagulation time and providing more accurate and reliable data support for electrolyte analysis.
