Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular to an inversion and mixing device for blood collection tubes. Background Art
[0002] A blood collection tube is a collection tube for blood specimens and also a test tube. The quantitative vacuum in the blood collection tube provides power for the blood collection process and realizes quantitative collection. The blood collection tube contains no additives and is suitable for routine biochemical serum tests. In medical units such as hospitals or disease control centers, for the purpose of detection or diagnosis and treatment, it is often necessary to analyze human blood. Before blood test analysis, it is usually necessary to fully mix the blood specimens.
[0003] Currently, the commonly used method is for medical staff to hold the test tube and shake it to achieve manual mixing. This is not only time-consuming and laborious, but also due to the different proficiency levels of medical staff, the mixing effect may not be ideal, and blood coagulation or hemolysis may occur, ultimately resulting in deviations in the test results. At the same time, in new drug clinical trials, subjects often undergo intensive blood collection after drug administration, and researchers need to be accurate to the second at the PK collection time point. To ensure the smooth progress of the research, usually two people are required to cooperate to complete the above operations, which is time-consuming and laborious. When a large number of blood collection tubes need to be mixed, the labor intensity and physical consumption of medical staff are increased. Utility Model Content

[0033] Please refer to Figure 1 and Figure 2, in one or more embodiments, a device for inverting and mixing a blood collection tube is provided, which includes a housing 100. A cavity 101 is formed inside the housing 100. An expansion motor 102 and a controller 103 are arranged inside the housing 100. The output end of the expansion motor 102 extends into the cavity 101 and is connected to a lifting plate 104. A rotation motor 105 is arranged inside the lifting plate 104. The output end of the rotation motor 105 extends into the cavity 101 and is provided with a rotating plate 106. A clamping assembly is arranged inside the rotating plate 106. Both the expansion motor 102 and the rotation motor 105 are electrically connected to the controller 103; a test tube rack 200 is placed inside the cavity 101. A placement groove 201 is formed inside the test tube rack 200. A blood collection tube 300 is placed inside the placement groove 201. A sealing door 120 is hinged to the front of the housing 100. A placement window is formed inside the housing 100. The placement window is communicated with the cavity 101. The sealing door 120 can block the placement window.
[0034] In this embodiment, the blood collection tube 300 is placed in the placement groove 201 of the test tube rack 200 and pushed into the cavity 101. The expansion motor 102 changes the height through the lifting plate 104 and the rotating plate 106, and the clamping assembly clamps the blood collection tube 300. Subsequently, the expansion motor 102 restores to the starting height through the lifting plate 104, the rotating plate 106 and the blood collection tube 300. Subsequently, the rotation motor 105 drives the rotating plate and the fixed blood collection tube 300 to rotate, so as to achieve the effect of inverting and mixing. When the inverting and mixing is completed, the expansion motor 102 is started again to displace through the lifting plate 104, the rotating plate 106 and the blood collection tube 300, insert the blood collection tube 300 into the placement groove 201, and the clamping assembly stops clamping the blood collection tube 300. Subsequently, the expansion motor 102 drives the lifting plate 104 and the rotating plate 106 to restore to the starting height; the center line of the rotation motor 105 and the center line of the rotating plate 106 are on the same horizontal line; it should be noted that the rotation times of the blood collection tube 300 in the new drug clinical trial are 6-8 times, and the specific actual rotation times are adjusted according to the actual situation.
[0035] Please refer to Figure 1 , Figure 2 and Figure 6 , in some embodiments, the clamping assembly includes a return spring 107, an electromagnet 108, a pressing plate 109 and a magnetic block 110. A through hole 111 and a groove 112 are formed inside the rotating plate 106. The return spring 107 is arranged inside the groove 112. A pressing plate 109 is connected to the surface of the return spring 107 and is located inside the groove 112. The magnetic block 110 is arranged inside the pressing plate 109. The electromagnet 108 is arranged inside the rotating plate 106. The electromagnet 108 is electrically connected to the controller 103. The pressing plate 109 is made of an elastic material. The center of the placement groove 201 and the center of the through hole 111 are on the same axis.
[0036] In this embodiment, the starting state electromagnet 108 is in the energized state, and thus will attract the magnetic block 110, causing the pressing plate 109 to displace in the direction of the electromagnet 108. At this time, the return spring 107 is in a compressed state, and the pressing plate 109 is located in the groove 112. When the blood collection tube 300 passes through the through hole 111, the power supply to the electromagnet 108 is stopped. At this time, there is no attraction to the magnetic block 110, and under the action of the return force of the return spring 107, the pressing plate 109 contacts the blood collection tube 300, thereby achieving the clamping and fixing effect on the blood collection tube 300. The firmness of the fixation depends on the return force of the return spring 107, and the selection of the elastic material of the pressing plate 109 can protect the blood collection tube 300. The centers of the placement groove 201 and the through hole 111 are on the same axis, which can effectively ensure the fixation of the blood collection tube 300 by the clamping assembly. The number of the clamping assemblies matches the number, position and size of the placement groove 201, and the size of the inner cavity 101 in the housing 100 and the size of the rotating plate 106 are adjusted according to the sizes of the clamping assemblies and the test tube rack 200 to ensure that the rotating plate 106 will not contact the inner wall of the cavity 101 when rotating at an appropriate height.
[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, an encoder 113 is provided on the surface of the rotation motor 105. The encoder 113 is electrically connected to the controller 103. A distance sensor 114 is provided inside the housing 100. The distance sensor 114 is electrically connected to the controller 103. A timer 115 is provided inside the housing 100. The timer 115 is electrically connected to the controller 103. A display screen 116 and a warning lamp 117 are provided on the front surface of the housing 100. Both the display screen 116 and the warning lamp 117 are electrically connected to the controller 103. A battery 118 is provided inside the housing 100. The battery 118 is used to supply power to the telescopic motor 102, the rotation motor 105, the electromagnet 108, the encoder 113, the distance sensor 114 and the timer 115. A charging hole 119 is provided on the back surface of the housing 100.
[0038] In this embodiment, the rotary motor 105 is a speed-adjustable motor. The encoder 113 can monitor the speed of the rotary motor 105. The timer 115 mainly controls the rotation time of the rotary motor 105. The cooperation of the encoder 113 and the timer 115 can adjust the rotation speed and shaking duration of the blood collection tube 300 according to the actual situation. The distance sensor 114 monitors the lifting height of the telescopic plate. By presetting the height, when the lifting plate 104 reaches the set height, the telescopic motor 102 stops working to avoid height errors affecting the inversion and mixing effect. At the same time, during a single inversion and mixing process, the telescopic motor 102 needs to drive the lifting plate 104 to change height twice, and the distance sensor 114 can monitor the height change of the lifting plate 104. Therefore, when the height of the lifting plate 104 returns to the set height every two times, the indicator light 117 emits light to prompt the medical staff to pick up the blood collection tube 300. The display screen 116 can display the inversion and mixing duration of the blood collection tube 300. The battery 118 can supply power to the telescopic motor 102, the rotary motor 105, the electromagnet 108, the encoder 113, the distance sensor 114, and the timer 115. The charging hole 119 can charge the battery 118.
[0039] It should be noted that the specific model specifications of the battery 118, the telescopic motor 102, the rotary motor 105, the electromagnet 108, the encoder 113, the distance sensor 114, and the timer 115 in this disclosure need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here. Their power supply and principles are clear to those skilled in the art and will not be described in detail here. The connection and installation of each part and the signal transmission principle belong to the well-known technology in the field.
[0040] Specifically, the working principle of a blood collection tube inversion and mixing device provided by this application is as follows:
[0041] Place the blood collection tube 300 in the placement groove 201 of the test tube rack 200 and push it into the cavity 101. The telescopic motor 102 changes the height through the lifting plate 104 and the rotating plate 106. When the blood collection tube 300 passes through the through hole 111, power supply to the electromagnet 108 is stopped at this time. At this time, there is no attraction to the magnetic block 110. Under the resilience of the return spring 107, the pressing plate 109 contacts the blood collection tube 300, thereby achieving the clamping and fixing effect on the blood collection tube 300. Subsequently, the telescopic motor 102 drives the lifting plate 104, the rotating plate 106, and the blood collection tube 300 to return to the starting height through the lifting plate 104. Subsequently, the rotary motor 105 drives the rotating plate and the fixed blood collection tube 300 to rotate, thereby achieving the inversion and mixing effect.
[0042] After inversion and mixing, start the telescopic motor 102 here to displace through the lifting plate 104, the rotating plate 106 and the blood collection tube 300, and insert the blood collection tube 300 into the placement groove 201. At this time, energize the electromagnet 108. After being energized, the electromagnet 108 has magnetism and will attract the magnetic block 110, causing the pressing plate 109 to displace towards the electromagnet 108. At this time, the return spring 107 is in a compressed state, and the pressing plate 109 is located in the groove 112, so that the clamping of the blood collection tube 300 cannot be realized. Subsequently, the telescopic motor 102 drives the lifting plate 104 and the rotating plate 106 to return to the starting height;
[0043] Among them, the rotation motor 105 uses a motor with adjustable speed. The encoder 113 can monitor the speed of the rotation motor 105. The timer 115 mainly controls the rotation time of the rotation motor 105. The cooperation of the encoder 113 and the timer 115 can adjust the rotation speed and mixing duration of the blood collection tube 300 according to the actual situation. The distance sensor 114 monitors the lifting height of the telescopic plate. Through the preset height, the telescopic motor 102 can be stopped after the lifting plate 104 reaches the set height to avoid height errors affecting the inversion and mixing effect. At the same time, during a single inversion and mixing process, the telescopic motor 102 needs to drive the lifting plate 104 to change its height twice, and the distance sensor 114 can monitor the height change of the lifting plate 104. Therefore, when the height of the lifting plate 104 returns to the set height every two times, the indicator light 117 can emit light to prompt the medical staff to pick up the blood collection tube 300.
