Description

Technical Field

[0001] This invention relates to the field of lactate analyzer technology, and specifically discloses a lactate analyzer for assessing athletic ability. Background Technology

[0002] In modern testing, lactate analyzers are instruments specifically designed to determine the lactate content in samples. Their core value lies in providing the necessary lactate concentration information for subsequent analysis and applications, helping users understand the specific composition of this substance in the sample. These instruments have practical applications in multiple fields, particularly in sports and medicine. In sports, they are often used to assist in sports-related assessments. For example, understanding an athlete's lactate levels helps determine if training intensity is meeting expectations, and also provides insights into the athlete's physical condition, allowing for adjustments to training plans and making training more targeted. In medicine, they can be used to monitor patients' conditions, especially critically ill patients, helping medical staff promptly grasp key metabolic information. Furthermore, in the diagnosis of certain diseases, the lactate-related information they provide can offer valuable reference points for diagnosis. From a developmental perspective, since its inception, lactate analyzers have gradually improved their adaptability and practicality in practical applications as people's needs for lactate detection have changed and the requirements for testing work in related fields have increased. Today, they have become an important testing tool in the fields of sports monitoring and medical testing, providing effective support for users and playing an important role in meeting daily testing needs and assisting in related work.

[0003] Traditional lactate analyzers require manual replacement of the puncture needle during blood collection or multiple people sharing a pillow. This can lead to bacterial infections or infections in subsequent users if one person has a genetic disease, thus affecting the health of the person being tested. Therefore, a lactate analyzer for assessing athletic ability was invented to address this deficiency. Summary of the Invention

[0040] The working principle of this device is as follows.

[0041] (a) During operation, the person to be tested places their hand between the first slider 105 and the second slider 106, then extends their index finger and presses it on the puncture needle 111, then removes their index finger from the puncture needle 111, then squeezes their index finger and drips the blood through the discharge cylinder 202 into the test box 201. Then the oxygen pump 204 starts and blows oxygen into the test box 201. Then the lactic acid in the blood reacts with the lactate oxidase coating on the working electrode and oxygen to generate H2O2, which in turn generates an oxidation current. The current intensity is proportional to the concentration of H2O2 generated. The higher the content of lactic acid in the blood, the more H2O2 is generated. Then the concentration of H2O2 is converted into an electrical signal by the signal conversion circuit and then displayed on the display screen 3.

[0042] (II) After a person performs an inspection, the first electric cylinder 112 is activated. The first electric cylinder 112 drives the third slider 114 to slide along the inner wall of the second slide groove 113, and then drives the third connecting shaft 412 to slide sequentially along the vertical groove, inclined groove and horizontal groove of the irregular groove 402 through the first connecting rod 103. During this process, the second connecting rod 404 drives the receiving seat 411 to slide sequentially along the outer surface of the vertical axis and inclined axis of the crank shaft 413. When the third connecting shaft 412 enters the horizontal groove of the irregular groove 402, the receiving seat 411 disengages from the crank shaft 413 and the gear 409 meshes with the rack 414. The third connecting shaft 412... As 12 continues to slide along the horizontal groove of the irregular groove 402, the gear 409 gradually rotates under the action of the rack 414, and then drives the puncture needle 111 to rotate through the receiving seat 411. When the gear 409 moves to the farthest point of the rack 414, the first contact shaft 417 contacts the contact switch. At this time, the end face of the receiving seat 411 is perpendicular to the intermediate plate 405. At this time, the puncture needle 111 and the adsorption block 419 are located directly above the needle drop groove 420. At this time, the first electric cylinder 112 and the electromagnet stop working. After the electromagnet loses its elasticity, the puncture needle 111 and the adsorption block 419 fall into the collection box 421 through the needle drop groove 420.

[0043] (III) The third electric cylinder 504 is started. The third electric cylinder 504 pushes the puncture needle 111 into the drive ring 427 through the push block 507. When the puncture needle 111 and the adsorption block 419 are completely inside the intermediate box 422, the second electric cylinder 425 is started and drives the drive ring 427 to descend through the intermediate rod 428. When the second electric cylinder 425 extends to its maximum extension, the adsorption block 419 is coaxial with the receiving seat 411. At this time, the electromagnet restarts and adsorbs the adsorption block 419 through the electromagnet, thereby completing the replacement of the new puncture needle 111. Then the first electric cylinder 112 moves in the opposite direction and brings the puncture needle 111 back to its original position. When the photoelectric switch detects the receiving seat 411, the pressure pump is started. The pressure pump sprays the disinfectant alcohol in the water tank 407 onto the puncture needle 111 through the nozzle 408, thereby completing the disinfection of the puncture needle 111. Then the new testing process continues.
