Description

Technical Field

[0001] This utility model relates to the technical field of high-altitude acclimatization testing equipment, and in particular to a high-efficiency portable high-altitude acclimatization index testing equipment. Background Technology

[0002] With socio-economic development and improved living standards, tourism, exploration, resource development, and military activities in plateau regions are becoming increasingly frequent. However, the unique low-oxygen and low-pressure environments of plateau regions significantly impact human physiological functions, easily triggering altitude sickness and altitude-related illnesses, seriously threatening people's health and safety.

[0003] Altitude acclimatization is the process by which the human body gradually adapts to the special environment of low oxygen after entering a high-altitude region. Blood indicators are the most accurate and direct way to detect this adaptation process, mainly including red blood cell count (RBC), hematocrit (hct), and blood oxygen saturation (SpO2).

[0004] Currently, hematocrit analyzers are complex to operate, have long testing times, require frequent cleaning, and are bulky and inconvenient to carry, making them unsuitable for frequent relocation and use at high altitudes. Furthermore, using a hematocrit analyzer requires professional personnel for venous blood collection and instrument operation, placing high demands on both the testing environment and the operator's technical skills, making it unsuitable for non-professionals to conduct tests at high altitudes.

[0005] Blood oxygen saturation meters are easy to operate, mostly with a finger clip design, and can quickly detect blood oxygen saturation values. However, external factors can affect the accuracy of the test results, and they can only detect blood oxygen saturation as an indicator, which cannot fully reflect the overall adaptation of the human body in a high-altitude environment.

[0006] Therefore, developing a set of efficient and accurate equipment for detecting high-altitude acclimatization and adaptation is of great practical significance. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a highly efficient and portable high-altitude acclimatization index detection device, which enables hematocrit detection to be performed without location restrictions, whether in daily home health monitoring or in medical rescue in outdoor or remote areas. It can also easily perform hematocrit and blood oxygen saturation detection, so as to quickly and accurately formulate response measures.

[0008] To solve the above-mentioned technical problems, the high-efficiency portable high-altitude acclimatization index detection device provided by this utility model adopts the following technical solution: A highly efficient and portable high-altitude acclimatization indicator detection device includes a microfluidic chip, a blood collection device, and a portable detector. The microfluidic chip is equipped with a three-electrode system for collecting sample detection signals. The portable detector contains an integrated hematocrit detection module, a blood oxygen saturation detection module, a control and processing module, and a display and interaction module. The three-electrode system is connected to the receiving end of the hematocrit detection module via electrical signals. The blood collection device includes a housing, a blood collection microneedle fitted inside the housing, and a blood reservoir inserted and slidably connected inside the housing. The blood collection end of the blood collection microneedle is located outside the housing, and the bleeding end is located inside the housing. The blood reservoir is connected to the bleeding end of the blood collection microneedle.

[0009] By adopting the above technical solution, hematocrit and blood oxygen saturation are important indicators for assessing the body's acclimatization and adaptation to high altitudes. Integrating the hematocrit and blood oxygen saturation detection modules into a single device, the system processes the signals after detection through a control and processing module before transmitting them to a display and interaction module for presentation. This device can quickly and simultaneously provide both data points, helping doctors and users to more comprehensively and accurately understand the body's adaptation to the high-altitude environment, comprehensively assess the presence of altitude sickness or other problems, and thus formulate more precise response measures, such as whether oxygen therapy is needed, whether travel plans should be adjusted, or whether further treatment is required. Simultaneously, the integrated device can quickly and sequentially complete hematocrit and blood oxygen saturation measurements without switching between different devices, significantly saving testing time and obtaining comprehensive health data in a short time. This is particularly beneficial in emergency situations or large-scale personnel testing, significantly improving testing efficiency. Furthermore, the integrated design avoids the inconvenience of carrying multiple independent testing devices. For people in high-altitude areas, whether travelers, researchers, or long-term residents, this reduces the burden of carrying equipment, allowing for easy testing of these two key indicators in high-altitude environments, thus improving usability.

[0010] Simultaneously, fingertip blood can be collected via a microneedle. The collected blood enters a reservoir, which transfers it to the sample application port of a microfluidic chip. The chip is then inserted into the hematocrit detection module to complete the hematocrit test. This invention innovatively miniaturizes the hematocrit analyzer and upgrades traditional venous blood collection to a portable fingertip blood test, reducing patient discomfort and the complexity of blood collection. Venous blood collection typically requires professional operation and a specific environment, while fingertip blood testing can be performed by patients at home or in other locations, offering convenience and speed, especially suitable for those requiring frequent testing. Furthermore, the microfluidic chip accurately detects hematocrit, is compact, portable, and easy to operate. Its precise results help doctors accurately assess the patient's condition, providing a reliable basis for diagnosis and treatment.

[0011] Optionally, the blood collection microneedle includes a pad body, a needle, and several microneedles. The needle and several microneedles are respectively fixed to both ends of the pad body. The pad body is fitted inside the outer cylinder, the needle is located inside the outer shell, and the microneedles are located outside the outer shell. The pad body has a pad cavity, the needle has a first inner hole, and the microneedles have a second inner hole. The first inner hole, the pad cavity, and the second inner hole are connected in sequence. The blood collection device is under negative pressure. The blood collection device has an opening at the end facing the needle, and the opening is covered with a silicone cap. The silicone cap can abut against the needle.

[0012] By employing the above-described technical solution, during blood collection, the outer shell is placed on the skin surface and pressed down, causing the microneedle to puncture the subcutaneous capillaries. Simultaneously, the blood reservoir is pressed down, causing it to slide downwards and press down on the needle, which then penetrates the silicone cap. Under the suction of negative pressure within the blood reservoir, blood sequentially flows through the first inner hole, the pad cavity, and the second inner hole into the reservoir. After blood collection, the blood reservoir is removed, the silicone cap is removed, and the blood is added to the sample application port of the microfluidic chip, thus completing the fingertip blood collection. Through the ingenious combination of the outer shell, blood reservoir, silicone cap, needle, and microneedle, the operation of blood collection, transfer, and administration can be completed conveniently and at low cost, reducing the complexity of blood collection. Patients can perform this procedure themselves at home or in other locations, making it convenient and quick. Furthermore, the blood collection microneedles and blood reservoir are low-cost and can be used as disposable consumables, achieving low-cost, clean, and safe blood collection.

[0013] Optionally, the length of the microneedle is 0.3-0.5 mm, and the diameter of the second inner hole is 0.1-0.2 mm.

[0020] By adopting the above technical solution, through the setting of the blood reservoir cavity and the blood collection microneedle cavity, the microneedle can be stably inserted into the skin when the outer shell is pressed down, and at the same time, the blood reservoir can be stably slid downward and press down the needle and be penetrated by the needle.

[0021] Optionally, an adsorption membrane is fixedly connected to the opening of the blood collection microneedle cavity. The adsorption membrane is arranged around the central axis of the outer shell, and several microneedles are located inside the adsorption membrane.

[0022] By adopting the above technical solution, the outer shell is placed on the skin surface, the outer shell is pressed down, and the air gap between the outer shell and the skin is eliminated through the adsorption membrane, so that the microneedle can be stably inserted into the skin for blood collection.
