[0027] Currently, when nurses draw blood from a vein, they need to manually invert the disposable vacuum tube 180°, 4 to 10 times (citrate blood collection tubes are inverted 4 to 5 times, and other test tubes are inverted at least 5 to 10 times). The tube must not be shaken violently to avoid hemolysis.

[0028] However, if nurses operate with inconsistent force, non-standard angles, and irregular times, it will result in poor specimen quality and hemolysis, which will affect the quality of the test. Sometimes blood needs to be re-drawn for testing, causing unnecessary pain to the patient and waste of blood.

[0029] To this end, the present invention provides a disposable vacuum tube shaker.

[0030] Reference Figure 1In one embodiment of the present invention, the shaker includes at least one mixing device 100, and the mixing device 100 includes a main unit 10, a rocker arm 20 and a test tube rack 30; the main unit 10 is provided with a controller and a driving mechanism electrically connected to the controller; the rocker arm 20 is drivingly connected to the driving mechanism, and the rocker arm 20 is provided with a supporting surface, and the driving mechanism is used to drive the rocker arm 20 to rotate under the control of the controller and make the supporting surface rotate from a first plane to a second plane, and the angle between the first plane and the second plane is less than or equal to 180°; the test tube rack 30 is installed on the supporting surface and is provided with at least one test tube fixing position 301 for fixing the test tube.

[0031] In this embodiment, the controller may be a single chip microcomputer, a DSP, an FPGA, etc. The driving mechanism may be a servo motor, etc., which is not limited here.

[0032] In this embodiment, the rocker arm 20 and the driving mechanism may be connected via a connecting shaft or other transmission mechanisms, which is not specifically limited here.

[0033] It should be noted that the test tube rack 30 is in a first plane in the initial position. The first plane may be a plane parallel to the table or the ground where the shaker is located, and the second plane may be a plane less than or equal to 180° with the first plane, which is not limited here.

[0034] To ensure the quality of blood samples, different types of blood samples should be inverted and mixed according to the requirements (citrate blood collection tubes should be inverted 4 to 5 times, and other test tubes should be inverted at least 5 to 10 times). Violent shaking is not allowed to prevent hemolysis. Therefore, it is necessary to ensure that the strength of the specimen inversion is uniform, the specimen inversion angle is standard, and the number of specimen inversions is accurate to the required number of times.

[0035] It can be understood that the present invention realizes automatic shaking of test tubes by adopting the shaker of the above-mentioned structure. The controller of the main unit 10 can control the inversion angle, speed and number of test tubes, thereby ensuring the quality of the specimens, saving time, improving operating efficiency, and effectively solving the problems of inconsistent operating force, non-standard angles, and non-standard times of medical staff.

[0036] In this embodiment, the shaker may further include a mounting platform 60. When there are multiple mixing devices 100, the multiple mixing devices 100 are detachably arranged at intervals on the mounting platform 60. In this way, the shaker can be disassembled into several independent devices, so that medical staff can carry them to the bedside for use, which improves the convenience of operation and is beneficial to improving work efficiency.

[0037] It is worth mentioning that the rotary mixers and blood mixers on the market are usually mixers used in laboratories and other institutions, and their rotation angle is 360°, which cannot meet the operation requirements of nurses to invert the test tubes 180° after blood collection and to invert various test tubes at different times. The shaker of the present invention is provided with multiple independently working mixing devices 100, which can not only meet the operation requirements of inverting the test tubes 180°, but also meet the requirements of inverting various test tubes at different times, greatly improving the convenience of operation and the efficiency of test tube inversion.

[0038] Reference Figure 1 In one embodiment, the test tube fixing position 301 may be a receiving hole opened on the test tube rack 30. In this embodiment, the number of receiving holes may be multiple, and the multiple receiving holes are evenly distributed on the test tube fixing position 301. In this way, multiple test tubes can be shaken at the same time, further improving work efficiency.

[0039] In this embodiment, the diameter of the receiving hole can be larger than the outer diameter of the test tube, and the hole wall of the receiving hole is provided with at least one limiting protrusion 302 along the radial direction of the receiving hole to clamp the test tube. In this way, the test tube can be fixed in the receiving hole more stably to avoid being separated from the test tube fixing position 301 due to vibration.

[0040] The limiting protrusion 302 may be a structure integrally formed with the test tube rack 30 , or may be a separate component, such as the flexible ball described below, etc., which is not limited here.

[0041] In order to meet the fixing requirements of test tubes of different specifications, based on the above embodiment, the limiting protrusion 302 can be retractably arranged on the hole wall of the receiving hole through an elastic member. Among them, the elastic member can be an elastic component such as a spring, and the matching limiting protrusion 302 can be composed of a flexible ball connected to the end of the spring, etc., which is not limited here.

[0042] To further ensure proper shaking of the test tube, turn it upside down 180°, refer to Figure 1 In one embodiment, the rocker arm 20 may be provided with a support plate forming a support surface, and the test tube rack 30 is installed against the support plate so that the test tube in the accommodating hole is perpendicular to the support plate.

[0043] Reference Figure 1 In one embodiment, the host 10 may be provided with a display screen 40, and the display screen 40 is electrically connected to the controller. Thus, the display screen 40 may display information such as the set rotation angle and number of times.

[0044] In this embodiment, the display screen 40 can be an LED display screen, an LCD display screen, etc., which is not limited here.

[0045] In addition, a button 50 may be provided on the host 10, and the button 50 is electrically connected to the controller to facilitate the user to control the operation of the shaker, thereby further improving the convenience of use.

[0046] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
