Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a novel blood sampling shaking device. Background Art

[0002] When using a blood sampling device to collect blood, sampling is required, and the sampled sample tube needs to be shaken so that the blood sample and anticoagulant in the sample tube are mixed evenly, avoiding blood sample sedimentation and coagulation, and facilitating subsequent testing of various physiological indicators. In the prior art, the shaking device for the sample tube is generally installed outside the housing of the blood sampling device. During the automatic shaking process, the shaking device swings from side to side outside the housing of the blood sampling device. Therefore, the device needs to occupy a large space for normal operation. In addition, a blood sampling scale for weighing the weight of the blood collection bag is generally installed on the blood sampling device. When the shaking device swings, the sample tube placed in the shaking device is likely to collide with the blood sampling scale. To avoid collisions, the distance between the shaking device and the blood sampling scale needs to be increased, resulting in an overly large device volume. Summary of the Utility Model

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, such as the terms "installation", "provided in", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] Refer to Figures 1 to 4As shown, the novel blood sampling and shaking device in this embodiment is used to collect blood and transport it to an external blood storage bag and a sample tube. It includes a housing 10, a frame 20 inside the housing 10, and a sample tube rack 30, a shielding device 40, and a driving module 50 installed on the frame 20. The sample tube rack 30, the shielding device 40, and the driving module 50 can be directly or indirectly installed on the frame 20. Here, the frame 20 is understood in a broad sense, and the mounting racks for installing components inside and outside the device are all part of the frame 20. There is a receiving cavity 60 inside the blood sampling and shaking device that communicates with the outside of the housing 10. The sample tube rack 30 is located outside the housing 10 and is used to place the sample tubes. The driving module 50 is drivingly connected to the sample tube rack 30 to drive the sample tube rack 30 to reciprocally and vertically flip and move between outside the housing 10 and inside the receiving cavity 60. The process of reciprocal vertical flipping makes the blood sample and anticoagulant in the sample tubes on the sample tube rack 30 mix evenly. The driving module 50 is also drivingly connected to the shielding device 40 to drive the shielding device 40 to open and close. The shielding device 40 is used to shield the receiving cavity 60. In the initial state, as Figure 1 and Figure 3 , the sample tube rack 30 is installed outside the housing 10 and is generally in a vertical state (including a vertical state or a slightly inclined state), which is convenient for the staff to place the sample tubes on the sample tube rack 30. The sample tubes are also generally in a vertical state with the sample tube openings facing upward. When the sampling of the sample tubes is completed and the shaking process is entered, as Figure 2 and Figure 4 , during the process of the sample tube rack 30 flipping and moving into the receiving cavity 60, the driving module 50 drives the shielding device 40 to open for the sample tube rack 30 to pass through. The sample tube rack 30 gradually flips to a generally horizontal state (including a horizontal state or a slightly upward or downward inclined state) inside the receiving cavity 60 and then flips out of the housing 10. When the sample tube rack 30 flips out of the housing 10, the driving module 50 drives the shielding device 40 to close to shield the receiving cavity 60. There is also a rear baffle 70 inside the receiving cavity 60. The rear baffle 70 is installed on the frame 20. Even when the shielding device 40 is open, the rear baffle 70 can protect the wires and components inside the device. This application uses the method of the sample tube rack 30 flipping and swaying into the device to make the blood sample and anticoagulant in the sample tubes mix evenly, and uses the shielding device 40 to automatically shield the receiving cavity 60 inside the device when the sample tube rack 30 moves to the outside of the housing 10, meeting the requirements of saving space and protecting the inside of the device.

[0040] In other embodiments (not shown in the figures), in the initial state, the sample storage tube rack 30 is installed outside the housing 10 in a substantially vertical state. The sample storage tubes are placed on the sample storage tube rack 30 and are also in a substantially vertical state with the mouths of the sample storage tubes facing upward. During the shaking operation, the sample storage tube rack 30 continuously rotates, and the driving module 50 drives the shielding device 40 to continuously open to allow the sample storage tube rack 30 to pass through. When the shaking operation ends and the sample storage tube rack 30 rotates to the outside of the housing 10, the driving module 50 drives the shielding device 40 to close to shield the receiving cavity 60. In this embodiment, the sample storage tube rack 30 can rotate to a substantially horizontal state within the receiving cavity 60 or can rotate to a substantially vertically downward state, that is, the sample storage tube rack 30 rotates 180°, and the mouths of the sample storage tubes face downward.

[0048] exist Figures 12 to 13 In the illustrated embodiment, the sample tube rack 30 is cylindrical and includes a plurality of racks 31, a transmission mechanism, an upper loading platform 32, a first motor 33, a lower loading platform 34, a second motor 35 and a base 36. The transmission mechanism includes a plurality of driven gears 37, a main gear 38 and a boss 39. The plurality of racks 31 are fixedly mounted on the plurality of driven gears 37 one by one, and the plurality of driven gears 37 are evenly mounted on the upper loading platform 32 through bearings along the circumferential direction of the upper loading platform 32. The main gear 38 is mounted on the upper loading platform 32 and meshes with the plurality of driven gears 37 one by one. The first motor 33 is mounted between the upper loading platform 32 and the lower loading platform 34. The rotating shaft of the first motor 33 is fixedly connected to the boss 39, and the boss 39 passes through the upper loading platform 32 and is fixedly connected to the main gear 38.

The upper loading platform 32 is fixedly connected to the lower loading platform 34, and the second motor 35 is fixedly installed on the base 36. The rotating shaft of the second motor 35 is fixedly connected to the lower loading platform 34 through the motor plate 310 to drive the multiple racks 31 on the upper loading platform 32 to revolve. Through the revolution, the multiple sample tubes are rotated to the preset position in turn to dock with the blood transfusion needle for puncture to complete the sampling. At the same time, the revolution method can also be used to shake evenly the reagents in the sample tubes.

[0049] The side of the storage rack 31 is provided with a slotted opening 311, and a tightening spring 312 is installed on the periphery of the storage rack 31. Under the action of the tightening spring 312, the inner diameter of the storage rack 31 shrinks to be smaller than the outer diameter of the sample retention tube. When the sample retention tube is inserted into the storage rack 31, the storage rack 31 expands, and its inner wall and the outer wall of the sample retention tube are closely attached to generate damping, so that the sample retention tube is not easily detached during the flipping process of the sample retention tube rack 30.

[0050] The bottom of the storage rack 31 is provided with an opening. The sample retention tube rack 30 is provided with a sample retention tube thimble 313 and a thimble detector 314.

The diameter of the return spring 315 is larger than the diameter of the opening and smaller than the diameter of the needle cap. The thimble detector 314 is located directly below the needle body. When the needle body of the sample retention tube thimble 313 approaches the thimble detector 314, it can be inductively detected. When the sample retention tube is placed in the storage rack 31, it is required to be inserted downward to the bottom. At this time, the sample retention tube thimble 313 slides to the lowest position, and the thimble detector 314 is triggered, and the indicator light is on, indicating that the sample retention tube is inserted normally. When there is no sample retention tube, under the action of the return spring 315, the sample retention tube thimble 313 resets to the highest position, and the thimble detector 314 is not triggered.

[0051] In the illustrated embodiment, it further includes a barcode scanner 80 for scanning the label on the sample retention tube. A barcode label for identifying the sample is pasted on the outer wall of the sample retention tube. When the sample retention tube rotates to a preset position opposite to the barcode scanner 80, the sample retention tube rotates, and the barcode scanner 80 can automatically identify the barcode. This function allows the user to insert the sample retention tube at any angle, reducing the usage requirements.
