Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and more specifically, relates to a device for processing blood samples from liver diseases. Background Technology

[0002] Blood samples from patients with liver disease are the core basis for assessing liver function and disease status. By testing liver function indicators such as transaminases, bilirubin, albumin, virological markers, liver fibrosis-related indicators, and complete blood count, the presence of liver damage, inflammation, metabolic abnormalities, or fibrosis can be directly reflected, providing key references for disease diagnosis, disease monitoring, and treatment plan adjustments.

[0003] Current blood sample processing equipment has been found to have at least the following problems:

[0004] First, in clinical liver disease blood sample testing scenarios such as hospital laboratories and health check-up centers, a large number of blood samples from different patients need to be processed daily. Due to the differences in the stage of liver disease and the body's metabolic status, the viscosity of their blood samples shows significant individual differences. In the blood sample processing, the mixing of blood and anticoagulant is a critical step, and it is necessary to ensure that the two are fully mixed to ensure the stability of the blood sample. When dealing with blood samples with high or low viscosity, the mixing rhythm is prone to mismatch with the characteristics of the blood sample, which may cause the anticoagulant to not be evenly dispersed in the blood, thus causing local coagulation of the blood sample. This will not only interfere with the normal conduct of subsequent tests, but may also lead to deviations in test data, affecting the doctor's accurate assessment of the patient's condition and the formulation of treatment plans.

[0005] Secondly, in blood sample processing environments such as clinical blood collection points and hospital laboratories, blood samples need to be quickly packaged and preserved, and the equipment needs to be cleaned and disinfected after collection to connect with subsequent testing processes and prepare for the next use. In the current blood sample processing flow, the packaging operation and equipment disinfection are mostly relatively independent steps. The packaging process requires manual assistance to complete the positioning and sealing, and the disinfection process also requires additional time and manpower to clean the pipelines and cavities. Under this separate operation mode, the efficiency of blood sample packaging is easily affected, and the blood sample may leak or deteriorate during transportation and storage due to untimely packaging or inadequate sealing. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a liver disease blood sample processing device.

[0007] A liver disease blood sample processing device includes a processing device housing, a blood collection channel fixedly installed on the processing device housing, a blood collection device housing a blood collection pump, a mixing chamber housing a mixing chamber housing a fixed mixing blade, a waste liquid storage tank below the mixing chamber a mixing and disinfection mechanism housing a mixing and disinfection mechanism that can mix blood with an anticoagulant after collecting patient blood, seal the mixed blood sample, and disinfect the pipes inside the device after each collection.

[0008] Preferably, the mixing disinfection mechanism includes a blood sample transport tube connected to a blood collection pump within the blood collection equipment. A mixing pipe is fixedly connected to the blood sample transport tube. One end of the mixing pipe is fixedly connected to a mixing chamber, and a disinfectant storage chamber is fixedly installed at the other end of the mixing pipe. A one-way valve is provided inside the mixing pipe. An anticoagulant pipe is fixedly installed through the lower end of the mixing chamber, and an outlet is provided on the anticoagulant pipe. An anticoagulant storage chamber is fixedly installed at the lower end of the anticoagulant pipe, and a hydraulic pump is provided inside the anticoagulant storage chamber. A stirring shaft is rotatably mounted on the anticoagulant pipe, connected to a motor, and fixedly mounted on the stirring shaft to a fixed stirring blade. An adaptive stirring blade is installed, which is connected to the fixed stirring blade via a torsion spring. Two openings are formed at the lower end of the mixing chamber. A sealing pipeline is fixedly installed at the lower end of the mixing chamber. Two electrically controlled valves are located below the mixing chamber, one of which is fixedly installed on the sealing pipeline. This valve controls the opening and closing of the lower opening of the mixing chamber. A blood sample sealer is located at the lower end of the sealing pipeline, and a blood sample storage tube is located below the sealer. A disinfection pipeline is fixedly installed at the lower end of the mixing chamber, and the other electrically controlled valve is fixedly installed on the disinfection pipeline. A waste liquid storage tank is fixedly connected below the disinfection pipeline, and an observation window is fixedly installed on the waste liquid storage tank.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this invention, a flexible and efficient stirring structure is constructed by using a motor-driven stirring shaft, combined with a fixed stirring blade and an adaptive stirring blade connected by a torsion spring. During stirring, the fixed stirring blade provides basic stirring power, while the adaptive stirring blade can dynamically adjust its unfolding angle according to the viscosity of the blood sample. When the blood sample viscosity is high, the stirring resistance will push it to flip and unfold, increasing the stirring cross-section and thus enhancing the stirring effect. When the viscosity is low, the adaptive stirring blade will naturally retract, maintaining a high stirring rate. This design does not require manual adjustment and can adapt to the viscosity differences of blood samples from different patients, allowing blood and anticoagulants to be quickly and uniformly mixed. It completely avoids the problems of blood sample coagulation and distorted test data caused by uneven mixing in traditional stirring methods, significantly improving the professionalism of blood sample processing and the reliability of test results.

[0011] In this invention, by providing a packaging and delivery channel, a blood sample packaging component, and a replaceable blood sample storage component, the mixed blood sample can be quickly filled and sealed, effectively preventing leakage and deterioration of the blood sample during subsequent transportation and storage, thus ensuring the integrity of the blood sample. At the same time, with the help of the integrated mixing and disinfection structure, the disinfection process can be automatically started after each blood sample collection. The disinfection liquid enters the mixing chamber through the delivery channel to thoroughly disinfect the internal pipes and chamber, greatly reducing the risk of secondary contamination and providing a clean environment for the next use.

[0012] In this invention, a waste liquid storage structure with a visual observation component allows medical staff to monitor the waste liquid level in real time, facilitating timely and standardized centralized treatment and improving the ease of use of the equipment. The entire device integrates functions such as blood collection, mixing, packaging, disinfection, and waste liquid collection. Through dual control valves, different workflows can be precisely switched, ensuring smooth and efficient operation without requiring complex manual operations by medical staff. This effectively reduces the workload of medical staff, meets the efficient and convenient operational needs in clinical medical scenarios, and improves the overall efficiency of blood sample processing.

[0013] This invention, by incorporating disposable blood collection components, a three-way transport structure for blood sample transportation and mixing, and a one-way control component near the disinfectant storage area, cuts off the path to cross-infection at the source of blood collection. It also effectively prevents blood backflow and cross-contamination between the disinfectant and blood, ensuring that the hygiene, safety, and purity of the blood sample remain unaffected throughout the entire collection and transportation process. This lays a solid foundation for the accuracy of subsequent blood sample processing and testing results, successfully solving the potential contamination hazards of traditional blood collection devices and meeting the stringent hygiene and safety requirements of clinical medicine.

[0023] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0024] Please see Figures 1-8This invention provides a blood sample processing device for liver disease, including a processing device housing 1. A blood collection channel 2 is fixedly installed on the processing device housing 1, and a blood collection device 3 is installed inside the blood collection channel 2. A blood collection pump is installed inside the blood collection device 3. The blood collection tubing inside the blood collection device 3 is changed after each use to prevent cross-infection. The blood collection device 3 can collect blood from the patient through an indwelling needle connected to the patient's vein. The blood collection device 3 is equipped with a pressure sensor and an adjustment mechanism. The adjustment mechanism can adjust the working power of the blood pump. Because liver disease patients may experience compensatory thickening of the blood vessel wall, reduction of elastic fibers, and narrowing of the lumen due to the disease, eventually leading to venous sclerosis, blood collection is prone to problems such as poor venous elasticity, which can easily cause tearing and bleeding of the vessel wall due to excessive suction force, or interruption of blood collection due to vascular collapse. The pressure sensor can effectively address these issues. The system continuously monitors the pressure within the blood collection tubing and presets a safety pressure threshold specific to patients with cirrhosis. When the pressure exceeds the limit, it immediately sends feedback to the regulating mechanism, which then dynamically reduces the suction force of the blood pump based on the sensor signal. This prevents continuous pressure from acting on fragile veins. The blood pump can also preset the volume of blood to be drawn (usually 5-10 ml) to ensure sufficient blood volume and prevent insufficient blood volume due to reduced blood flow caused by venous sclerosis in patients with liver disease, thus avoiding the need for a second blood draw. The processing device housing 1 has a mixing chamber 7, which contains a fixed stirring blade 10. The fixed stirring blade 10 is used to evenly mix the patient's blood with the anticoagulant. Below the mixing chamber 7 is a waste liquid storage tank 19, which is used to temporarily store the waste liquid generated during the operation of this device.

[0025] The processing device housing 1 is equipped with a mixing and disinfection mechanism. This mechanism can mix the blood with an anticoagulant after the patient's blood is collected through an indwelling venous needle, and then seal the mixed blood sample. It can also disinfect the pipes inside the device after each collection.

[0026] like Figures 1-8As shown, the mixed disinfection mechanism includes a blood sample transport tube 4, which is connected to the blood collection pump inside the blood collection device 3. A mixing pipe 6 is fixedly connected to the blood sample transport tube 4, forming a three-way structure. One end of the mixing pipe 6 is fixedly connected to the mixing chamber 7, which is used to transport freshly collected patient blood into the mixing chamber 7. The other end of the mixing pipe 6 is fixedly installed with a disinfectant storage chamber 5, which is used to hold the disinfectant. A one-way valve is provided at the end of the mixing pipe 6 near the disinfectant storage chamber 5. The patient inserts the indwelling needle on their arm into the blood collection channel 2 and connects it to the blood collection device 3. Then, the blood collection pump inside the blood collection device 3 operates, drawing a certain amount of blood from the patient's vein through the indwelling needle. During the blood sample collection process, a pressure sensor detects the pressure inside the blood collection tube and provides real-time feedback to the regulating mechanism to adjust the suction force of the blood pump, preventing damage to the patient's veins. After a sufficient amount of blood (5-10ml) is drawn, the blood pump automatically stops working. The blood is then transported through the blood sample transport tube 4 and the mixing tube 6 to the mixing chamber 7. Because a one-way valve is installed at the end of the mixing tube 6 near the disinfectant storage chamber 5, the blood only flows into the mixing chamber 7. An anticoagulant tube 8 is fixedly installed through the lower end of the mixing chamber 7, and an outlet is provided on the anticoagulant tube 8. An anticoagulant storage chamber 12 is fixedly installed at the lower end of the anticoagulant tube 8. The anticoagulant storage chamber 12 is used to store the anticoagulant and contains... A hydraulic pump is installed. When the patient's blood enters the mixing chamber 7, the hydraulic valve in the anticoagulant storage chamber 12 releases a certain amount of anticoagulant from the outlet at the top of the anticoagulant pipeline 8. A stirring shaft 9 is rotatably mounted on the anticoagulant pipeline 8. The stirring shaft 9 is connected to a motor and is fixedly mounted to a fixed stirring blade 10. An adaptive stirring blade 11 is rotatably mounted on the stirring shaft 9 and is connected to the fixed stirring blade 10 via a torsion spring. When the anticoagulant enters the blood sample, the stirring shaft 9 begins to rotate. The fixed stirring blade 10 and the adaptive stirring blade 11 on the stirring shaft 9 rotate synchronously. When the patient's blood viscosity is too high, the adaptive stirring blade 11, rotatably mounted on the stirring shaft 9 and connected to the fixed stirring blade 10 via a torsion spring, encounters resistance during rotation. The adaptive stirring blades 11 are rotated and expanded to increase the cross-section of the mixing. This design allows for adjustment of the expansion angle of the adaptive stirring blades 11 based on the varying viscosity of the patient's blood sample. Two openings are located at the lower end of the mixing chamber 7, and a sealing tube 13 is fixedly installed thereon. Two electrically controlled valves 14 are located below the mixing chamber 7, one of which is fixedly mounted on the sealing tube 13. The electrically controlled valve 14 controls the opening and closing of the lower opening of the mixing chamber 7. A blood sample sealer 16 is located at the lower end of the sealing tube 13, and a replaceable blood sample storage tube 17 is located below the blood sample sealer 16. The blood sample sealer 16 is used to fill and seal the blood sample within the blood sample storage tube 17. After the anticoagulant and blood sample are mixed...The electrically controlled valve 14 controls the opening of the corresponding sealing pipeline 13, allowing the blood sample to flow from the sealing pipeline 13 into the blood sample sealer 16, and then through the blood sample sealer 16 into the blood sample storage tube 17, where it is sealed. Medical personnel then remove the blood sample storage tube 17, label it, and place it in a low-temperature storage box. A disinfection pipeline 18 is fixedly installed at the lower end of the mixing chamber 7, and another electrically controlled valve 14 is fixedly installed with the disinfection pipeline 18. The electrically controlled valve 14 on the disinfection pipeline 18 controls the opening and closing of the corresponding opening on the disinfection pipeline 18 in the mixing chamber 7. Waste liquid... The storage tank 19 is fixedly connected below the disinfection pipeline 18. An observation window 20 is fixedly installed on the waste liquid storage tank 19, reflecting the liquid level inside. After medical personnel remove the blood sample storage tube 17, the device is self-cleaning. The water pump in the disinfection liquid storage chamber 5 controls the disinfection liquid to pass through the one-way valve in the mixing pipeline 6, entering the mixing chamber 7 for disinfection. The disinfection liquid is then discharged through the channel under the blood sample storage tube 17 into the waste liquid storage tank 19 for collection, awaiting further processing by medical personnel.

[0027] Processing device housing 1: As the basic support structure of the device, it is used to fix and install core components such as blood collection channel 2, mixing and disinfection mechanism, and waste liquid storage tank 19, providing a stable installation carrier and protection for internal components and ensuring the integrity of the overall structure.

[0028] Blood collection channel 2: A dedicated channel on the outer shell 1 of the processing device, through which the indwelling needle interface on the patient's arm is inserted and connected to the blood collection equipment 3, providing precise positioning and safety protection for the blood collection process, and ensuring the accuracy and standardization of the blood collection operation.

[0029] Blood collection device 3: Located in blood collection channel 2, it has a built-in blood collection pump, disposable blood collection tubing, pressure sensor and adjustment mechanism. It can collect blood through the patient's indwelling venous needle. During the blood collection process, the pressure sensor monitors the pressure in the blood collection tubing in real time. If it exceeds the safety threshold for patients with cirrhosis, it will feed back to the adjustment mechanism to dynamically reduce the power of the blood pump to avoid venous tearing or collapse. The blood pump can be preset to collect 5-10ml of blood. After the sufficient amount is collected, the pump will automatically stop to prevent secondary blood collection.

[0030] Blood sample transport tube 4: One end is connected to the blood collection pump in the blood collection equipment 3, and the other end is fixedly connected to the mixing pipe 6, forming a dedicated blood sample transport channel, responsible for stably transporting the collected blood sample to the mixing chamber 7.

[0034] Anticoagulant pipeline 8: The lower end is connected to the anticoagulant storage chamber 12, and the upper end is provided with a liquid outlet. It is responsible for accurately delivering the quantitative anticoagulant in the anticoagulant storage chamber 12 to the mixing chamber 7, providing a dedicated channel for blood sample anticoagulation processing.

[0035] Stirring shaft 9: Connected to the motor, with fixed stirring blade 10 and adaptive stirring blade 11 fixedly installed at the upper end. Its core function is to rotate at high speed under the drive of the motor, driving the two types of stirring blades to move synchronously, so as to achieve efficient mixing of blood sample and anticoagulant.

[0036] Fixed stirring blade 10: It is fixedly installed on the stirring shaft 9 and rotates synchronously with the stirring shaft 9. It is the basic structure for mixing blood samples and anticoagulants, and provides a stable and uniform stirring force for the mixing process.

[0037] Adaptive stirring blade 11: It is connected to the fixed stirring blade 10 by a torsion spring and is rotatably mounted on the stirring shaft 9. It can adaptively adjust the spreading angle according to the viscosity of the blood sample. The higher the viscosity, the greater the spreading range, effectively increasing the stirring cross-section and ensuring that blood samples of different viscosities can be mixed evenly.

[0038] Anticoagulant storage chamber 12: Used to store anticoagulants. It has a built-in hydraulic pump that can accurately release a quantitative amount of anticoagulant to the anticoagulant pipeline 8 according to the blood sample volume, providing dual protection for material storage and quantitative delivery for blood sample anticoagulation processing.

[0039] Encapsulation pipe 13: Connects the lower opening of the mixing chamber 7 to the blood sample encapsulator 16. It is a dedicated transport channel for the mixed blood sample, responsible for smoothly transferring the uniformly mixed blood sample to the encapsulation component for sealing.

[0040] Electrically controlled valves 14: There are two in total, which are installed on the sealing pipeline 13 and the disinfection pipeline 18 respectively. They control the opening and closing status of the corresponding pipelines through electrical control, so as to realize the orderly switching of blood sample sealing and waste liquid discharge processes.

[0041] Blood sample sealer 16: Located at the lower end of the sealing tube 13 and above the blood sample storage tube 17, its core function is to quickly fill the mixed blood sample into the blood sample storage tube 17 and seal the blood sample storage tube 17 to ensure the airtightness and integrity of the blood sample.

[0042] Blood sample storage tube 17: It adopts a replaceable design and is used to store sealed blood samples. It is convenient for medical staff to take the tube, label it and then store it at low temperature. It is the final storage carrier of blood samples and ensures the safety of blood sample transportation and storage process.

[0043] Disinfection pipeline 18: connects to another opening at the lower end of the mixing chamber 7 and the waste liquid storage tank 19, and is responsible for the directional transfer of the disinfected waste liquid to the waste liquid storage tank 19, providing a dedicated discharge channel for the disinfection waste liquid and avoiding waste liquid pollution.

[0044] Waste liquid storage tank 19: Fixed below the disinfection pipeline 18, it is used to temporarily store the disinfection waste liquid generated during the self-cleaning process of the device, providing a safe temporary storage space for centralized waste liquid treatment and ensuring the cleanliness of the operating environment.

[0045] Observation window 20: Installed on the waste liquid storage tank 19, it can intuitively reflect the liquid level of the waste liquid in the tank, making it convenient for medical staff to judge the amount of waste liquid in real time, carry out centralized treatment in a timely manner, and improve the ease of use of the equipment.

[0046] Working principle:

[0047] The first step involves the patient inserting the indwelling venous catheter connector on their arm into the blood collection channel 2, engaging it with the blood collection device 3. The device then begins operation; the built-in disposable blood collection tubing connects to the indwelling interface, and the blood collection pump provides stable negative pressure to draw venous blood. A pressure sensor within the device 3 monitors the pressure within the tubing in real time. If the pressure exceeds the safety threshold specific to cirrhotic patients, it immediately sends feedback to the adjustment mechanism, dynamically reducing the suction force of the blood collection pump. This process is tailored to the fragile nature of the patient's cirrhotic veins. The blood sample continues to be driven and smoothly transported to the mixing chamber 7 along the blood sample transport tube 4 and the mixing tube 6. Because the mixing tube 6 is equipped with a one-way valve at the end near the disinfectant storage chamber 5, it can completely avoid blood sample backflow and contamination, and prevent disinfectant from seeping back into the blood sample pipeline. The disposable blood collection tube of the blood collection equipment 3 strictly follows the principle of one person, one use, and one replacement, cutting off the cross-infection path from the source of blood collection, ensuring the purity of blood samples and the hygiene and safety of operation throughout the process, and providing a qualified original blood sample basis for subsequent processes such as mixing blood samples with anticoagulants and packaging.

[0048] In the second step, after the blood enters the mixing chamber 7, the hydraulic pump in the anticoagulant storage chamber 12 is activated, releasing a quantitative amount of anticoagulant into the chamber through the outlet of the anticoagulant pipeline 8. The motor drives the stirring shaft 9 to rotate, and the fixed stirring blade 10 and the adaptive stirring blade 11 rotate synchronously. The adaptive stirring blade 11 is connected to the fixed stirring blade 10 through a torsion spring, and can adaptively adjust the unfolding angle according to the viscosity of the blood sample to achieve uniform mixing. After mixing is completed, the electrically controlled valve 14 on the sealing pipeline 13 is opened, and the blood sample flows into the blood sample sealer 16 through the sealing pipeline 13, where it is filled and sealed into the replaceable blood sample storage tube 17 below. Medical staff will then take the tube, label it, and store it at low temperature.

[0049] Third, after the medical staff removes the blood sample storage tube 17, the device starts the self-cleaning program. The water pump in the disinfectant storage chamber 5 sends the disinfectant through the one-way valve of the mixing pipe 6 into the mixing chamber 7 to thoroughly disinfect the pipe and the inner wall of the chamber. The disinfected waste liquid flows through another opening at the lower end of the mixing chamber 7 and into the waste liquid storage tank 19 via the disinfection pipe 18 for temporary storage. The medical staff can check the liquid level through the observation window 20 on the waste liquid storage tank 19. The waste liquid will then be centrally and properly treated to ensure the cleanliness of the device for the next use.
