Description

Blood sample storage device and method

Technical Field

The invention belongs to the technical field of medical treatment, and particularly relates to a blood sample storage device and a blood sample storage method.

Background

Blood samples contain rich biological information including various biological indicators in blood cells, plasma and serum. Such information is critical for diagnosing and monitoring a variety of diseases, such as cancer, heart disease, infection, and immune diseases. In clinical practice, doctors can determine the blood type, blood glucose level, kidney function, liver function, and white blood cell count, etc. of patients through blood samples, which is critical for making treatment plans and monitoring disease progression.

Although modern hospitals use many advanced storage technologies, refrigerators remain a simple and effective way to store blood samples that need to be processed for a short period of time. This helps to ensure the quality and usability of the sample for timely clinical analysis and diagnosis.

Refrigerators are typically used for short-term storage of blood samples, typically over days or weeks, as they are capable of providing a constant and suitably low temperature environment. This helps to slow down cell breakdown, maintain stability of biomolecules in the sample, and reduce bacterial and microbial growth. Generally, these refrigerators may be set in different temperature ranges to meet the storage requirements of different types of samples.

However, the blood sample has a short period of validity, and requires periodic manual inspection and cleaning during storage in the refrigerator, which creates problems.

Manual cleaning of samples requires manual intervention and is subject to negligence by medical staff or laboratory technicians, resulting in expired samples being forgotten or not being handled in time. This may affect the diagnosis and treatment of the patient.

In addition, manually cleaning the sample is a time consuming and labor intensive task. Hospital and laboratory staff are required to periodically check the samples in the refrigerator for and clear expired samples. This consumes a lot of time and human resources. Sometimes, due to a busy work environment or other factors, the cleaning of the sample may be delayed, resulting in an excessive residence time of the sample in the refrigerator, thereby affecting its quality and usability.

Manually cleaning the sample may introduce risks, particularly when handling samples that may be contaminated. Handling expired biological samples may require additional precautions to be taken to reduce potential risks.

During manual cleaning, there is a possibility that erroneous samples are cleared or valid samples are mistaken for expired. This may result in loss of important data.

In view of the foregoing, it is an urgent need to provide a blood sample storage device for determining the validity period of a blood sample and transferring and storing the blood sample beyond the validity period.

Detailed Description

The technical scheme disclosed in the invention is described in detail in the following with reference to specific embodiments.

Techniques, methods known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate. In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.

The invention provides a blood sample storage device 100, as shown in fig. 1, comprising a refrigerator body 200, wherein the refrigerator body 200 comprises a refrigerator door, and a sample storage position 210 is arranged in the refrigerator body 200.

Wherein the sample storage bit 210 is configured to hold a blood sample. As one of the exemplary embodiments, the sample storage location 210 includes a sample well for holding a waste sample, as shown. The sample groove comprises a first clamping groove 211 and a second clamping groove 212 which are symmetrically arranged oppositely, and a cavity matched with the rear end part of the blood sample is formed on one side, opposite to the first clamping groove 211 and the second clamping groove 212, of the sample groove, so that the rear end part of the blood sample can be clamped after the blood sample is inserted, and the blood sample is fixed.

The sample tank is provided with an induction component, and the induction component comprises a timer and a validity period judging device.

Whether the sample groove is occupied by a blood sample or not can be judged by arranging a corresponding sensing component in the sample groove.

By way of example and not limitation, as shown in fig. 2, pressure sensors (not shown) are disposed on the contact surfaces of the first clamping groove 211 and the second clamping groove 212 with the blood sample, and when the blood sample is present in the sample groove, the blood sample will exert pressure on the contact surfaces of the first clamping groove 211 and the second clamping groove 212, and when the pressure sensors detect the pressure, it can be determined that the blood sample is occupied in the sample groove.

Alternatively, an infrared emitter (not shown) is provided below the sample well, and infrared light can pass through the hollow of the sample well without being blocked in the event that no blood sample is placed in the sample well. Under the condition that the blood sample is not placed in the sample groove, the infrared rays can be shielded by the bottom of the blood sample, and the situation that the blood sample occupies a place in the sample groove can be judged.

The timer counts a storage time of the blood sample placed in the sample tank while the blood sample is placed in the sample tank. A timer is associated with each sample slot to ensure that the storage time of each sample is tracked.

A preset standard storage time range, i.e. the expiration date of the blood sample, is set in the system. This time frame is set according to the needs and regulations of the hospital or laboratory, and the user can set according to his own needs. The determiner is configured to receive the data from the timer and compare the data with a predetermined threshold, i.e., a predetermined standard storage time range for the blood sample, to determine whether the blood sample is within a valid period.

If it is determined that the blood sample is not within the expiration date, the expiration date determination component triggers the aforementioned sample transfer apparatus to transfer the blood sample.

As one of the exemplary embodiments, the sample transfer apparatus 400 includes a manipulator. The manipulator is an automated device for grasping, moving and placing samples. It typically has multiple joints that enable movement in multiple directions, e.g., up and down, back and forth, side to side, rotation, etc. These motion capabilities allow the manipulator to operate precisely in three dimensions.

The manipulator is movably mounted on the manipulator track so that the manipulator can move in the refrigerator body during sample processing, so as to be able to approach each sample slot, thereby performing a grabbing operation on the blood sample.

The manipulator rail includes a vertical axis rail 430 and a horizontal axis rail.

Wherein the vertical axis track is arranged perpendicular to the ground, allowing the manipulator to move in an up-down direction. The robot can slide up and down along the vertical axis rail to achieve the grabbing and placing operations of the refrigerator body 200 in the vertical direction.

As shown in fig. 3, the cross-axis tracks include a first cross-axis track 410 and a second cross-axis track 420; the first transverse shaft rail 410 is movably mounted on the vertical shaft rail to be movable up and down along the vertical shaft rail. The robot arm may move on the vertical axis track to a first horizontal axis track 410 connected to the vertical axis track. By moving the first transverse shaft rail 410 up and down, the height of the manipulator in the refrigerator body 200 is changed, so that the manipulator can grasp and place blood samples in sample tanks with different heights.

The manipulator performs the operation of gripping and placing the blood samples in the same row of sample cells at the same height by moving left and right on the first lateral axis rail 410.

The vertical axis rail is movably mounted on the second horizontal axis rail 420 to be movable left and right along the second horizontal axis rail 420, allowing the robot to move left and right in the horizontal direction.

After the manipulator grips the blood sample, an operation of transferring it to the waste sample bin 300 is performed.

The refrigerator body 200 is provided with a waste sample bin 300 as shown; the waste sample bin 300 can be selectively communicated with the inside of the refrigerator body 200.

When the manipulator performs the transfer operation, the waste sample bin 300 is communicated with the inside of the refrigerator body 200, and the manipulator directly places the blood sample in the waste sample bin 300, thereby completing the transfer operation.

Preferably, the waste sample bin 300 is provided on a handle 500 on a refrigerator door. With this arrangement, the user can notice the waste sample chamber 300 during the process of opening the refrigerator door using the handle 500, thereby discarding the blood sample in the waste sample chamber 300.

In one embodiment, as shown in FIG. 1, the waste sample compartment 300 is disposed between a handle 500 and a refrigerator door.

The waste sample bin 300 is connected to a refrigerator door through a liftable bin door 330. When the bin gate 330 is opened, the waste sample bin 300 is communicated with the inside of the refrigerator body 200, the mechanical arm is close to the waste sample bin 300 through the mechanical track, the grabbed blood sample is placed in the waste sample bin 300, then the bin gate 330 is closed, and the waste sample bin 300 is not communicated with the inside of the refrigerator body 200.

In another embodiment, as shown in fig. 4, the handle 500 is disposed between the waste sample compartment 300 and the refrigerator door. The waste sample bin 300 includes a liftable back wall 340, typically located at the back of the waste sample bin 300. The rear wall 340 is fixedly connected to the handle 500 such that the handle 500 moves in synchronization with the rear wall 340 of the waste sample cartridge 300. The handle 500 is installed on the refrigerator door in a liftable manner, and the movement of the handle 500 on the refrigerator door is realized by providing sliding rails and corresponding sliding blocks on the refrigerator door and the handle 500 by way of example and not limitation.

The rear wall 340 and the handle 500 move upward synchronously, the waste sample bin 300 is communicated with the inside of the refrigerator body 200, and after the blood sample is placed in the waste sample bin 300, the rear wall 340 drives the handle 500 to move downward synchronously, and the waste sample bin 300 is not communicated with the inside of the refrigerator body 200.

Handling expired biological samples may require additional precautions to reduce potential risks, particularly when handling blood samples that may be contaminated.

Alternatively, a sample slot capable of receiving a fixed blood sample may also be provided within the waste sample cartridge 300, with a robotic arm placing the blood sample into the sample slot.

The waste sample bin 300 is provided with at least one side to be openable and closable.

For example, the upwardly facing side is configured to be openable and closable, and a user can access the interior of the waste sample compartment 300 by opening the upper cover.

Other sides may be configured to be openable and closable.

In another embodiment, as shown in fig. 5, the waste sample compartment 300 has a double-layered structure, and includes an inner housing 320 for separately storing the blood sample, and an outer housing 310 sleeved on the inner housing 320, wherein a sterilizing assembly is disposed in the inner housing. The provision of a double layer structure helps to ensure that expired blood samples remain isolated from the external environment and other samples, which reduces the risk of cross-contamination and infection.

The movement and storage of the sample is accomplished within the enclosed inner and outer housing 320, which helps to prevent contamination of the sample from the outside. Meanwhile, the operation of the manipulator reduces the chance of contact between operators and the waste liquid sample, and reduces the risk of infection and pollution.

In this embodiment, the back portions of the inner and outer cases facing the refrigerator door are both provided to be liftable. In the specific implementation, the following manner can be adopted: the manipulator is close to useless sample storehouse 300, and the back of shell body and inner casing is synchronous to be opened, and the manipulator stretches into in the inner casing, puts into the inner casing with the blood sample, and the manipulator is kept away from useless sample storehouse afterwards, and the back same part of shell body and inner casing moves down to close, or the back of shell body moves down earlier and closes, and with useless sample storehouse and refrigerator body isolation, then closes the back of inner casing again.

By first isolating the spent sample compartment 300 from the refrigerator body 200 and then closing the inner housing, a double isolation is achieved. This means that even if the inner housing is not completely sealed or a problem arises, the blood sample will not come into contact with the refrigerator environment, reducing the potential risk of contamination.

In the case of insulation between the inner and outer cases of the waste sample bin 300 and the inside of the refrigerator, the possibility of contamination and infection of the blood sample is reduced by sterilizing the blood sample in the inner case by providing a sterilizing assembly (not shown in the drawing) in the inner case.

Optionally, the inner housing of the waste sample cartridge is provided with a transparent window (not shown) in the outer housing through which the condition of the inner housing can be seen without punching the waste sample cartridge.

The present invention also provides a blood sample storage method by a blood sample storage device 100 according to any one of the above, comprising the steps of: a blood sample is placed on the sample storage location 210.

Timing the storage time of the waste liquid sample on the sample storage position 210 and judging whether the blood sample is still in the valid period; if not, triggering a waste liquid transferring operation, and transferring the blood sample exceeding the effective period into the waste sample bin 300.
