Description

Technical Field

[0001] This utility model relates to sampling equipment, specifically to a multi-sample tube cutting and sampling device. Background Technology

[0002] After plasma collection, it is necessary to retain the plasma for testing. Therefore, a sample retention tube was designed to store the plasma sample. The sample retention tube is supported by plastic material and heat-sealed at both ends to facilitate transfer and transportation between the sampling and testing processes.

[0003] In the existing technology, when testing plasma in a sample collection tube, the operator's operating steps are as follows: First, prepare scissors and a receiving tube; second, cut the sample collection tube with scissors, and the plasma drips into the receiving tube, while the end of the sample collection tube also falls into the receiving tube; third, use tweezers to hold the end of the sample collection tube in the receiving tube.

[0004] Although the above steps can extract samples from the sample tube, they still have the following drawbacks: because one hand holds the sample tube and the other holds the scissors, it is not possible to hold multiple sample tubes at once when cutting the end of the sample tube. This is because it is impossible to maintain the spacing between multiple sample tubes when holding them, which can cause different plasmas to mix and result in inaccurate test results. Utility Model Content

[0005] This utility model aims to provide a multi-sample tube cutting and sampling device to solve the problem of low detection efficiency caused by the inability to cut multiple sample tubes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a multi-sample tube cutting and sampling device, comprising: a sampling frame, a lifting clamping seat, a test tube positioning frame, a guiding filter device, a punching execution device, and a lifting drive device; a lifting clamping seat is installed on the sampling frame, the lifting clamping seat is used to clamp at least two sample tubes to be sampled in the vertical direction, and the lifting clamping seat can be raised and lowered relative to the sampling frame; a test tube positioning frame is installed on the sampling frame, the test tube positioning frame is used to store and receive test tubes, and the test tube positioning frame is located below the receiving test tubes; a guiding filter device is installed between the test tube positioning frame and the lifting clamping seat, and the guiding filter device is aligned with the test tube positioning frame; a punching execution device is installed on the sampling frame, the punching execution device is used to punch the sample tubes on the lifting clamping seat; the lifting clamping seat is connected to the output end of the lifting drive device, and the lifting drive device is installed on the top of the sampling frame.

[0007] Preferably, the guiding filter device includes: a support positioning seat and a guiding filter seat. The top surface of the support positioning seat is recessed to form an installation groove for the guiding filter seat to be inserted. The bottom wall of the installation groove has an opening that penetrates the support positioning seat. The guiding filter seat has at least two guiding holes located above the opening. The guiding holes have a funnel-shaped structure. A filter screen is installed at the bottom of the guiding holes for the plasma flowing out of the sample retention tube to pass through.

[0008] Preferably, the lifting clamping seat includes a sliding seat and a rotating cover. The sliding seat can be lifted and lowered relative to the sampling frame. The sliding seat is connected to the output end of the lifting drive device. The sliding seat has at least two insertion slots for inserting the sample tube to be sampled. The top of the sliding seat is hinged to the top of the rotating cover. The rotating cover is used to cooperate with the sliding seat to clamp the sample tube to be sampled in the insertion slot.

[0009] Preferably, a fixed blade is fixed at the bottom of the sliding seat, and the output end of the punching actuator is used to cooperate with the fixed blade to cut the sample tube to be sampled.

[0010] Preferably, a rotary blocking mechanism is installed at the support positioning seat. The rotary blocking mechanism can be rotated to a position that presses the rotating cover tightly onto the sliding seat, or it can be rotated to a position that deviates from the rotating cover.

[0011] Preferably, an elastic part is connected between the rotary blocking mechanism and the support positioning seat. The elastic force of the elastic part is used to make the rotary blocking mechanism deviate from the position of the rotary cover. The rotary blocking mechanism is provided with an action part, which is used to press the rotary cover onto the sliding seat by acting on the guide filter seat located in the mounting groove.

[0012] Preferably, the rotary blocking mechanism includes a rotary shaft and a clamping arm. The rotary shaft is rotatably mounted on the support positioning seat, and the clamping arm is fixed to the rotary shaft. The clamping arm is used to press the rotary cover against the sliding seat.

[0013] Preferably, the actuating part is an extension arm, one end of which is fixed to the rotating shaft, and the other end of which is used to press against the guide filter seat located in the mounting groove.

[0014] Preferably, the elastic part is a spring sheet, and the edge of the support positioning seat is provided with a rotating groove for the extension arm to rotate. The inner wall of the rotating groove is fixed to one end of the spring sheet, and the other end of the spring sheet is fixed to the extension arm.

[0015] Compared with the prior art, this utility model has the following beneficial effects: In this application, firstly, a lifting clamping seat is set to clamp the sample retention tube located in the vertical direction; then, a test tube positioning frame is designed to position the receiving test tube located below the sample retention tube, ensuring that the receiving test tube on the test tube positioning frame can be aligned with the sample retention tube located on the lifting clamping seat; next, a lifting drive device is designed to lower the sample retention tube clamped by the lifting clamping seat, so that the sample retention tube is close to the receiving test tube located on the test tube positioning frame; finally, a punching execution device is designed to punch the sample retention tube clamped by the lifting clamping seat, so that the bottom end of the sample retention tube is cut off, and the plasma flows into the receiving test tube under its own gravity, thereby realizing the transfer of plasma from at least two sample retention tubes to the receiving test tube. In the above process, it is not necessary to hold at least two sample collection tubes tightly by hand, avoiding the inability to maintain the gap between adjacent sample collection tubes due to holding them by hand, thus preventing the mixing of different plasmas and ensuring the quality of the sampled plasma. Furthermore, since the end of the sample collection tube may fall off when it is cut off, a guiding filter device is designed. The guiding filter device guides the plasma in the sample collection tube to the receiving tube and also prevents the end from falling into the receiving tube. The guiding filter device only needs to be cleaned before each sampling, avoiding the need to use tweezers to remove the end, which would reduce the operation efficiency.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, this utility model discloses a multi-sample tube cutting and sampling device, including: a sampling frame 1, a lifting clamping seat 2, a test tube positioning frame 3, a guiding filter device 4, a punching execution device 5, and a lifting drive device 6; the lifting clamping seat 2 is installed on the sampling frame 1, and the lifting clamping seat 2 is used to clamp at least two sample tubes 7 to be sampled in the vertical direction, and the lifting clamping seat 2 can be raised and lowered relative to the sampling frame 1; the test tube positioning frame 3 is installed on the sampling frame 1, and the test tube positioning frame 3 is used to store and receive test tubes 8, and the test tube positioning frame 3 is located below the receiving test tubes 8; the guiding filter device 4 is installed between the test tube positioning frame 3 and the lifting clamping seat 2, and the guiding filter device 4 is aligned with the test tube positioning frame 3; the punching execution device 5 is installed on the sampling frame 1, and the punching execution device 5 is used to punch the sample tubes on the lifting clamping seat 2; the lifting clamping seat 2 is connected to the output end of the lifting drive device 6, and the lifting drive device 6 is installed on the top of the sampling frame 1.

[0023] The lifting drive device 6 can be a pneumatic cylinder, a hydraulic cylinder, or other linear drive devices.

[0024] The punching execution device 5 includes a punching blade 51, a punching base 52, and a punching cylinder 53. The piston rod of the punching cylinder 53 is fixed to the punching base 52, and the punching base 52 is fixed with the punching blade 51. The punching blade 51 is the output end of the punching execution device 5. The punching cylinder 53 drives the punching base 52 and the punching blade 51 to move in the horizontal direction. The punching blade 51 cooperates with the fixed blade 23 to cut off the middle end of the sample retention tube 7 to be sampled.

[0025] In this application, the guiding filter device 4 includes a support positioning seat 41 and a guiding filter seat 42. The top surface of the support positioning seat 41 is recessed to form an installation groove for the guiding filter seat 42 to be inserted. An opening penetrating the support positioning seat 41 is provided in the bottom wall of the installation groove. The guiding filter seat 42 has at least two guiding holes 420 located above the opening. The guiding holes 420 have a funnel-shaped structure, and a filter screen is installed at the bottom of the guiding holes 420, allowing plasma flowing from the sample collection tube 7 to pass through. The guiding filter seat 42 does not allow the end of the sample collection tube 7 to pass through. The funnel-shaped structure of the guiding holes 420 in the guiding filter seat 42 guides the plasma into the receiving tube 8. The guiding filter seat 42 is made of a high-density material. When the guiding filter seat 42 is placed in the installation groove, it cannot move relative to the support positioning seat 41 due to its own weight, facilitating cleaning of the guiding filter seat 42 after each use.

[0026] In this application, the lifting clamping seat 2 includes a sliding seat 21 and a rotating cover 22. The sliding seat 21 can be lifted and lowered relative to the sampling frame 1. The sliding seat 21 is connected to the output end of the lifting drive device 6. The sliding seat 21 has at least two insertion slots for inserting the sample tube 7 to be sampled. The top of the sliding seat 21 is hinged to the top of the rotating cover 22. The rotating cover 22 is used to cooperate with the sliding seat 21 to clamp the sample tube 7 located in the insertion slot. The top of the sliding seat 21 is hinged to the top of the rotating cover 22, so that under the weight of the rotating cover 22 itself, the rotating cover 22 can be kept in a snap-fit ​​state with the sliding seat 21 and the sample tube 7 to be sampled can be clamped.

[0027] In order to cut off the middle end of the sample retention tube 7, a fixed blade 23 is fixed at the bottom of the sliding seat 21, and the output end of the punching execution device 5 is used to cooperate with the fixed blade 23 to cut the sample retention tube 7.

[0028] In this application, a rotary blocking mechanism 9 is installed at the support positioning seat 41. The rotary blocking mechanism 9 can rotate to a position that presses the rotating cover 22 tightly onto the sliding seat 21, or it can rotate to a position that deviates from the rotating cover 22. Since the rotating cover 22 inevitably wobbles relative to the sliding seat 21 when the lifting drive device 6 drives the sliding seat 21 to rise and fall, the rotary blocking mechanism 9 is designed to prevent the rotating cover 22 from wobbling relative to the sliding seat 21 when the sliding seat 21 is lowered, thus releasing the sample retention tube 7 to be sampled.

[0029] In this application, an elastic part 91 is connected between the rotary blocking mechanism 9 and the support positioning seat 41. The elastic part 91 has a spring force that causes the rotary blocking mechanism 9 to deviate from the position of the rotating cover 22. The rotary blocking mechanism 9 is provided with an action part 92, which acts on the guide filter seat 42 located in the mounting groove to press the rotating cover 22 onto the sliding seat 21. The spring force of the elastic part 91 achieves the following: when the guide filter seat 42 is not placed in the mounting groove, the elastic part 91 keeps the rotary blocking mechanism 9 deviating from the position of the rotating cover 22. At this time, the rotating cover 22 can be rotated to replace the new sample retention tube 7. When the sample tube 7 to be sampled is clamped in the lifting clamping seat 2, the cleaned guide filter seat 42 is placed in the mounting groove. The guide filter device 4 pushes the action part 92, so that the rotary blocking mechanism 9 rotates to the position of pressing the rotary cover 22 on the sliding seat 21. When the lifting drive device 6 drives the lifting clamping seat 2 to lower, the rotary blocking mechanism 9 always presses the rotary cover 22, thereby maintaining the state of the rotary cover 22 pressing the sliding seat 21.

[0030] In this application, the rotary blocking mechanism 9 includes a rotating shaft 93 and a clamping arm 94. The rotating shaft 93 is rotatably mounted on the support positioning seat 41, and the clamping arm 94 is fixed to the rotating shaft 93. The clamping arm 94 is used to press the rotating cover 22 against the sliding seat 21. The design of the rotating shaft 93 allows the entire rotary blocking mechanism 9 to rotate relative to the support positioning seat 41, and the clamping arm 94 can also rotate with the rotating shaft 93.

[0031] Preferably, the actuating part 92 is an extension arm, one end of which is fixed to the rotating shaft 93, and the other end of which is used to press against the guide filter seat 42 located in the mounting groove. The design of the extension arm allows the guide filter seat 42 to push the extension arm to rotate, and the extension arm drives the rotating shaft 93 and the pressing arm 94 to rotate together, so that the pressing arm 94 on the rotating shaft 93 and the rotating cover 22 are pressed against the sliding seat 21.

[0032] In this application, the elastic part 91 is a spring sheet, and the edge of the support positioning seat 41 has a rotating groove for the extension arm to rotate. The inner wall of the rotating groove is fixed to one end of the spring sheet, and the other end of the spring sheet is fixed to the extension arm. The rotating groove allows the extension arm to rotate and provides space for the installation of the spring sheet.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
