[0028] Embodiment 1: on the basis of the technical problem that the existing blood and anticoagulant are prone to uneven mixing and affect the anticoagulation effect, the present embodiment provides a blood collection anti-coagulation device, as shown in Figures 1 to 5 The outer frame body 1 is internally slidably installed with the inner frame body 2, the inner frame body 2 is internally slidably installed with the work frame body 3 accommodating blood collection test tubes, the anti-coagulation structure 4 includes a driving body 41, a horizontal anti-coagulation assembly 42 and a longitudinal anti-coagulation assembly 43, the driving body 41 is installed on the inner bottom of the outer frame body 1, the horizontal anti-coagulation assembly 42 and the longitudinal anti-coagulation assembly 43 are sequentially fixedly installed on the surface of the driving body 41, the driving body 41 synchronously drives the horizontal anti-coagulation assembly 42 and the longitudinal anti-coagulation assembly 43 to work, thereby respectively driving the inner frame body 2 to horizontally reciprocate and the work frame body 3 to longitudinally reciprocate, so that the work frame body 3 is driven to horizontally reciprocate when the inner frame body 2 horizontally reciprocates, and the work frame body 3 can also longitudinally reciprocate by itself, thereby the work frame body 3 in the horizontal and longitudinal slight shaking and oscillation of the test tube for collecting blood, thereby avoiding the blood in the test tube to be deposited and coagulated for a long time.
[0029] It needs to be particularly and importantly explained that the test tube in the present embodiment should adopt the test tube with anticoagulant or add anticoagulant into the test tube, the horizontal and longitudinal slight shaking and oscillation of the work frame body 3 in the present embodiment can make the anticoagulant and blood fully mix and uniformly distribute, thereby avoiding the blood and anticoagulant to be deposited, thereby better preventing the blood from coagulating and improving the anticoagulation effect.
[0030] As shown in Figures 1 to 5 , especially Figure 2 The driving body 41 includes a driving motor 411 and a rotating shaft 412, the driving motor 411 is fixedly installed on the inner bottom of the outer frame body 1, the rotating shaft 412 is fixedly installed on the output shaft of the driving motor 411, and the rotating shaft 412 is rotatably installed in the outer frame body 1. The driving motor 411 drives the rotating shaft 412 to rotate, thereby driving the horizontal anti-coagulation assembly 42 and the longitudinal anti-coagulation assembly 43 to work through the rotation of the rotating shaft 412.
[0031] As Figures 1 to 5 shown, the horizontal anti-coagulation assembly 42 comprises a gear 421 and a rack 422, the gear 421 is fixedly installed on the surface of the rotating shaft 412, and the rack 422 is fixedly installed on the bottom of the inner frame 2.
[0032] During the rotation of the rotating shaft 412, the gear 421 synchronously rotates with the rotating shaft 412 to engage the rack 422, so that the horizontal movement of the inner frame 2 is driven by the rotation of the gear 421, and then the horizontal movement of the inner frame 2 can drive the workbench 3 and the test tube contained in the workbench 3 to move horizontally, thereby preventing the blood and the anticoagulant from being deposited and coagulated for a long time, and at the same time, the anticoagulant can be uniformly distributed, and the mixing effect of the anticoagulant and the blood is improved, thereby facilitating the improvement of the anticoagulation performance of the blood.
[0033] It should be noted that in the embodiment of the present disclosure, the driving motor 411 adopts a bidirectional motor capable of forward and reverse rotation, the bidirectional motor reversely rotates 180° after rotating 180°, that is, the bidirectional motor rotates half a circle forward and then reverses half a circle, and such cyclic rotation drives the rotating shaft 412 and the gear 421 to synchronously rotate forward and reversely, thereby interfering with the horizontal reciprocating movement of the inner frame 2, the workbench 3 and the test tube inside, thereby on the one hand, avoiding the deposition of the blood and the anticoagulant for a long time, and on the other hand, improving the mixing effect of the blood and the anticoagulant, and facilitating the uniform distribution of the anticoagulant to improve the anticoagulation effect.
[0034] As Figures 1 to 5 shown, the longitudinal anti-coagulation assembly 43 comprises a cam 431 and a lug 432, the cam 431 is fixedly installed on the surface of the rotating shaft 412, and the lug 432 is fixedly installed on the bottom of the workbench 3 and penetrates the bottom of the inner frame 2.
[0035] When the rotating shaft 412 rotates, the rotating shaft 412 drives the cam 431 to synchronously rotate, so that the lug 432 is intermittently contacted by the cam 431 during the rotation of the cam 431, and the lug 432 is lifted by the cam 431 when the cam 431 contacts the lug 432, thereby driving the workbench 3 to move longitudinally when the lug 432 is lifted by the cam 431.
[0036] When the rotating shaft 412 rotates forward and reversely by 180°, the gear 421 and the cam 431 are synchronously driven to rotate forward and reversely by 180°, thereby driving the inner frame 2 to move horizontally reciprocatingly and the workbench 3 to move longitudinally reciprocatingly.
[0037] As Figures 1 to 5As shown in the disclosure, the first flexible member 5 is fixedly installed at the bottom of the working frame body 3. The first flexible member 5 is an air bag, and the structure principle of the air bag is prior art, which will not be described here. The first flexible member 5 is used to avoid the violent rigid impact between the working frame body 3 and the inner frame body 2 when the working frame body 3 moves longitudinally, thereby protecting the working frame body 3. The first flexible member 5 can also be a spring, but it should be noted that when a spring is used, the working frame body 3 has a stronger longitudinal shaking effect than the air bag, and a person skilled in the art can select according to the actual situation.
[0038] It should be noted that the first flexible member 5 can also be fixedly installed on the inner wall surface of the bottom of the inner frame body 2.
[0039] As shown in the disclosure, Figure 1 and 3 The outer frame body 1 is horizontally provided with a first sliding groove 11, the inner frame body 2 is fixedly provided with a first sliding body 21 which slides in the first sliding groove 11, the inner wall of the inner frame body 2 is longitudinally provided with a second sliding groove 22, and the outer wall of the working frame body 3 is longitudinally fixedly provided with a second sliding body 31.
[0040] The inner frame body 2 horizontally slides in the outer frame body 1 through the first sliding body 21, and the working frame body 3 longitudinally slides in the inner frame body 2 through the second sliding body 31. Through the cooperation of the first sliding groove 11 and the first sliding body 21, and the second sliding groove 22 and the second sliding body 31, the smooth and stable movement of the inner frame body 2 and the working frame body 3 can be ensured.
[0041] Embodiment 2: Based on the above embodiment 1, only the differences between embodiment 1 and embodiment 2 will be described below, and the same parts will not be described.
[0042] As shown in the disclosure, Figure 3 The outer frame body 1 and the inner frame body 2 are fixedly provided with an elastic member 6 on the horizontal opposite surfaces. The elastic member 6 is a spring, and the second elastic member 6 can reset the inner frame body 2 after horizontal movement. It should be noted that the elastic force of the second elastic member 6 on the inner frame body 2 should be opposite to the movement direction of the gear 421 driving the rack 422, so that after the gear 421 drives the rack 422 to move, the second elastic member 6 can reset the inner frame body 2 through its own elastic potential energy.
[0043] It needs to be particularly pointed out that the gear 421 is provided with gear teeth in a fan-shaped structure on the surface. Thus, the driving member can adopt a common motor that cannot rotate bidirectionally, and the gear 421 intermittently engages the rack 422 through the gear teeth in a fan-shaped structure by the continuous rotation of the driving member in one direction, so that the rack 422 is driven to move horizontally when the gear 421 engages the rack 422, and the rack 422 is reset by the second elastic member 6 when the gear 421 disengages the rack 422. In this way, the gear 421 can ensure the rack 422 and the inner frame body 2 to move reciprocatingly and horizontally by the intermittent engagement of the gear teeth and the reset of the second elastic member 6 6, thereby preventing the blood and the anticoagulant from being deposited or coagulated for a long time, and being conducive to improving the mixing effect and the anticoagulation effect of the blood and the anticoagulant.
[0044] As shown in Figure 3 , Figure 4 and Figure 5 , the first damping member 7 is fixedly installed on the horizontally opposite surface of the outer frame body 1 and the inner frame body 2, and the second damping member 71 is fixedly installed on the longitudinally opposite surface of the inner frame body 2 and the working frame body 3. The first damping member 7 and the second damping member 71 both adopt a hydraulic damping rod, and the structure and principle of the hydraulic damping rod are prior art, which will not be described in detail here.
[0045] The first damping rod can prevent the inner frame body 2 and the working frame body 3 from moving horizontally, especially from resetting too violently, thereby avoiding the damage of the test tube caused by the violent movement of the test tube, facilitating the slow horizontal movement of the inner frame body 2, the working frame body 3 and the test tube, and being conducive to keeping the test tube stable and safe during the horizontal movement.
[0046] The second damping rod can prevent the working frame body 3 from moving longitudinally, especially from resetting too violently, thereby facilitating the slow movement of the working frame body 3 and the test tube in the longitudinal direction, avoiding the damage of the working frame body 3 and the test tube caused by the too rapid movement of the working frame body 3 and the test tube in the longitudinal direction, and being conducive to keeping the working frame body 3 and the test tube moving stably and safely.
[0047] The second flexible member 51 is fixedly installed on the side wall of the inner frame body 2 in the horizontal reset movement direction, and the kinetic energy of the inner frame body 2 during the reset can be slowed down through the second flexible member 51, thereby avoiding the damage of the inner frame body 2 caused by the too rapid movement of the inner frame body 2 during the horizontal movement, and being conducive to protecting the inner frame body 2, the working frame body 3 and the test tube rack.
[0048] It needs to be pointed out that the driving motor 411 in the embodiment 1 adopts a bidirectional motor that can rotate forward and backward, which can stably and accurately control the rotation of the gear 421 and the horizontal movement path and speed of the inner frame body 2, thereby avoiding the rigid contact between the inner frame body 2 and the outer frame body 1 during the movement of the inner frame body 2. Therefore, the structure for slowing down the movement kinetic energy is not needed to be installed on both sides of the movement direction of the inner frame body 2.
[0049] The working process in the embodiment 2 of the present disclosure:
[0050] The driving motor 411 is started to drive the rotating shaft 412 to rotate synchronously, the rotating shaft 412 drives the gear 421 and the cam 431 to rotate synchronously, the gear 421 intermittently engages the rack 422 through the gear teeth distributed in the sector structure, so that the rack 422 is driven to move horizontally when the gear 421 engages the rack 422, and the rack 422 is reset through the second elastic member 6 when the gear 421 disengages the rack 422, so as to drive the inner frame body 2 to move reciprocatingly horizontally, thereby preventing the blood and the anticoagulant from being deposited or coagulated for a long time, and being conducive to improving the mixing effect and the anticoagulation effect of the blood and the anticoagulant.
[0051] The rotating shaft 412 drives the gear 421 to rotate and drives the cam 431 to rotate, the cam 431 rotates intermittently to contact the lug plate 432, and the lug plate 432 is lifted up by the cam 431 when the cam 431 contacts the lug plate 432, so as to drive the working frame body 3 to move longitudinally when the lug plate 432 is lifted up by the cam 431, thereby enabling the test tube to move longitudinally reciprocatingly while moving horizontally reciprocatingly, so as to further prevent the blood and the anticoagulant from being deposited or coagulated for a long time, and being conducive to improving the mixing effect and the anticoagulation effect of the blood and the anticoagulant.
[0052] When the inner frame body 2 moves horizontally and the working frame body 3 moves longitudinally, the elastic member 6 can reset the inner frame body 2, the working frame body 3 can be automatically reset by gravity, and the first flexible member 5 can protect the working frame body 3 and the test tube from being subjected to a violent rigid impact. The first damping member 7 and the second damping member 71 can limit the inner frame body 2 and the working frame body 3 from being reset too rapidly and being damaged, thereby being conducive to improving the safety during use.
[0053] It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
