Description

Technical Field

[0001] The invention relates to the technical field of blood testing, and in particular to a shaking device for testing venous blood samples in a hematology department. Background Art

[0002] At present, in current medical work, it is sometimes necessary to fully shake the collected human blood and anticoagulant to ensure the anticoagulant effect. This requires shaking the test tube for a long time to fully mix the blood and anticoagulant. Blood shaking is widely used in hematology. After the venous blood specimen of the hematology department is collected, the test tube needs to be gently rotated and shaken immediately to fully mix the blood and anticoagulant. This can prevent the blood from coagulating during transportation or storage, thereby avoiding affecting the test results.

[0003] At present, there are some existing technologies that can automatically shake multiple test tubes. For example, the patent publication number is CN114432954B. Its main technical means is to fully shake the blood in the container through the cooperation between the flat gear and the rack, and the flat gear and the rack are repeatedly engaged and separated. A downward pressure mechanism is provided, and the wedge block presses the connecting rod outward, so that the connecting rod drives the clamping block to open, so as to reduce the tediousness of manual operation. The disadvantage of this technical solution is that the blood sample should be sent for inspection as soon as possible after shaking to avoid long-term retention and causing the blood sample to become However, the above scheme cannot automatically withdraw the test tube after shaking, and the blood sample cannot be sent for inspection in time, which will cause long-term retention and induce changes in the blood sample. It is also very easy to cause long-term shaking of the blood sample, resulting in violent shaking of it, and violent shaking may cause hemolysis, that is, red blood cells rupture and release hemoglobin, which will affect the results of certain blood test items. Based on this, the present invention provides a shaking device for venous blood sample testing in the hematology department, which has a simple and ingenious structure and can automatically withdraw the test tube after the blood sample is shaken to remind medical staff to take out the test tube for inspection. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a shaking device for testing venous blood samples in hematology to solve the technical problem that the blood samples cannot be sent for testing in time due to the inability to automatically withdraw the test tube after shaking.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A shaking device for venous blood specimen detection in hematology comprises: a base, on which a plurality of test tube racks are arranged in a circle, the base is provided with a plurality of rotating wheels, the plurality of test tube racks are respectively fixed on the plurality of rotating wheels, and the base is provided with a rotating assembly for driving the plurality of rotating wheels to rotate and rotate on its own; a supporting cylinder, in which a supporting cylinder for carrying the top of a test tube is movably installed in each test tube rack, and a middle cylinder is installed at the bottom of each supporting cylinder, and a bottom cylinder for carrying the bottom of the test tube is installed at the bottom of each middle cylinder, when the test tube is placed in the supporting cylinder, the test tube slides down along the middle cylinder until its bottom abuts against the bottom cylinder, at which time the bottom cylinder abuts against a transmission disk fixed at the central axis of the rotating wheel; and a withdrawal assembly, which is installed on the rotating wheel, and when the number of self-rotation of the rotating wheel reaches a threshold value, the withdrawal assembly drives the middle cylinder to rise, and then the supporting cylinder and the bottom cylinder rise synchronously, and the bottom cylinder separates from the transmission disk and stops rotating.

[0006] As a further solution of the present invention: the top of the support tube is bucket-shaped.

[0007] As a further solution of the present invention: an anti-skid pad is arranged on the contact surface between the transmission disc and the bottom cylinder.

[0008] As a further solution of the present invention: the withdrawal assembly includes: a rotation sensor, which is installed on the rotating wheel and is used to monitor the number of rotations of the rotating wheel; and an electromagnetic module, which is fixed in the test tube rack, a magnetic block is fixed on the middle cylinder, and the magnetic block is slidably installed on the inner wall of the test tube rack, the magnetic block is located above the electromagnetic module, and the two repel each other magnetically.

[0009] As a further solution of the present invention: an elastic member is connected between the middle tube and the bottom tube, and the middle tube is connected to the bottom tube via a connecting rod, and the connecting rod is a telescopic structure.

[0010] As a further solution of the present invention: the range of action of the magnetic repulsion force between the electromagnetic module and the magnetic block is greater than the maximum deformation of the elastic member.

[0011] As a further solution of the present invention: the rotating assembly includes: a rotating disk, which is rotatably mounted on the base, and whose central axis is driven to rotate by an external driving source, a plurality of gears are rotatably mounted on the rotating disk, and the plurality of gears are coaxially fixed on a plurality of rotating wheels respectively; and a ring gear, which is fixed on the base and coaxially mounted with the rotating disk, the plurality of gears are all located inside the ring gear, and the plurality of gears are all meshed with the ring gear.

[0012] Beneficial effects of the present invention: (1) In the present invention, a plurality of rotating wheels are driven by a rotating assembly to rotate about the axis of the central axis of the base and to rotate on their own at the same time, so that the test tubes rotate synchronously and rotate on their own, so that the blood and anticoagulant in the test tubes can be fully shaken and mixed; when the number of self-rotation of the rotating wheels reaches a threshold, it indicates that the test tubes have been shaken sufficiently, and at this time the withdrawal assembly is started and drives the middle cylinder to rise, so that the support cylinder rises synchronously and slides relative to the test tube rack, and at the same time the bottom cylinder rises and separates from the transmission disk, so that the bottom cylinder stops rotating, so that the test tubes stop rotating; after the support cylinder is raised, the medical staff is reminded to take out the test tubes in the support cylinder and send them for inspection in time, and during this process, the test tubes stop rotating on their own, so that the test tubes can be prevented from rotating for a long time after being shaken, resulting in failure to send them for inspection in time, or from being violently shaken and causing red blood cells to rupture, thereby affecting the blood test results.

[0013] (2) In the present invention, after the test tube is placed in the support tube, the test tube slides down along the middle tube until its bottom abuts against the bottom tube. Then, under the action of the gravity of the test tube, the test tube pushes the bottom tube to continue to descend, and the elastic member gradually stretches until the bottom tube abuts against the transmission disk. Then, the transmission disk drives the test tube to rotate through the bottom tube. This method can ensure that the test tube enters the test tube rack in a slow manner and is gradually driven to start rotating. It can reduce the damage to the test tube caused by collision when the test tube is placed, and can also minimize the violent shaking caused by the test tube starting to rotate.

[0014] (3) After the blood and anticoagulant in the test tube are evenly shaken, the magnetic repulsion between the electromagnetic module and the magnetic block drives the magnetic block to rise, and the elastic part stretches slightly to its maximum deformation state. Then the magnetic block continues to rise and drives the middle tube, the support tube and the bottom tube to rise synchronously, so as to achieve the lifting of the support tube and the stopping of the rotation of the bottom tube.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 As shown, the present invention is a shaking device for venous blood specimen detection in hematology, comprising: a base 1, on which a plurality of test tube racks 2 are arranged in a circumference, a plurality of rotating wheels 3 are arranged on the base 1, the plurality of test tube racks 2 are respectively fixed on the plurality of rotating wheels 3, and a rotating assembly 9 for driving the plurality of rotating wheels 3 to rotate and rotate is arranged on the base 1; a supporting cylinder 4, in which a supporting cylinder 4 for carrying the top of the test tube is movably installed, and a middle cylinder 5 is installed at the bottom of each supporting cylinder 4, and a bottom cylinder 6 for carrying the bottom of the test tube is installed at the bottom of each middle cylinder 5. When the test tube is placed in the supporting cylinder 4, the test tube slides down along the middle cylinder 5 until its bottom abuts against the bottom cylinder 6, and at this time, the bottom cylinder 6 abuts against the transmission disk 8 fixed at the central axis of the rotating wheel 3; and a withdrawal assembly 7, which is installed on the rotating wheel 3. When the number of self-rotation of the rotating wheel 3 reaches a threshold, the withdrawal assembly 7 drives the middle cylinder 5 to rise, and the supporting cylinder 4 and the bottom cylinder 6 rise synchronously, and the bottom cylinder 6 is separated from the transmission disk 8 and stops rotating.

[0020] In one case of this embodiment, the support tube 4 and the test tube rack 2 are slidably matched and rotationally matched, and the support tube 4 and the middle tube 5 are rotationally matched.

[0021] When the embodiment is actually used, the medical staff puts the test tube into the support tube 4, and the test tube slides down along the middle tube 5 until its bottom abuts against the bottom tube 6. At this time, the bottom tube 6 abuts against the transmission disk 8, and the rotating assembly 9 drives the plurality of rotating wheels 3 to rotate about the axis of the central axis of the base 1, and rotates at the same time. In this process, the test tube rotates synchronously and rotates by itself, so that the blood and anticoagulant in the test tube can be fully shaken and mixed; when the number of self-rotation circles of the rotating wheel 3 reaches the threshold, it means that the test tube is shaken enough, and at this time the withdrawal assembly 7 is started and drives the middle tube 5 to rise, then the support tube 4 rises synchronously and slides relative to the test tube rack 2, and at the same time the bottom tube 6 rises and separates from the transmission disk 8, then the bottom tube 6 stops rotating, so that the test tube stops rotating; after the support tube 4 is raised, the medical staff is reminded to take out the test tube in the support tube 4 and send it for inspection in time, and the test tube stops rotating in this process, which can avoid the test tube still rotating for a long time after being shaken, resulting in failure to send it for inspection in time, or causing violent shaking to cause red blood cells to rupture, thereby affecting the blood test results.

[0022] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the top of the support tube 4 is bucket-shaped; in actual application, the bucket-shaped design can facilitate medical staff to put in the test tube.

[0023] like Figure 3-Figure 6 As shown, as a preferred embodiment of the present invention, an anti-skid pad 12 is provided on the contact surface between the transmission disk 8 and the bottom cylinder 6; in actual application, the anti-skid pad 12 can increase the friction between the test tube and the transmission disk 8, thereby ensuring that when the rotating wheel 3 rotates, the test tube can be driven to rotate synchronously through the transmission disk 8.

[0024] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the withdrawal component 7 includes: a rotation sensor 701, which is installed on the rotating wheel 3 and is used to monitor the number of rotations of the rotating wheel 3; and an electromagnetic module 702, which is fixed in the test tube rack 2, and a magnetic block 703 is fixed on the middle cylinder 5, and the magnetic block 703 is slidably installed on the inner wall of the test tube rack 2, and the magnetic block 703 is located above the electromagnetic module 702, and the two repel each other magnetically.

[0025] In one case of this embodiment, the rotation sensor 701 utilizes the principles of electromagnetic induction, photoelectric effect or magnetoresistance effect to detect rotational motion and converts it into an electrical signal, so as to monitor the number of rotations of the rotating wheel 3; the rotation sensor 701 and the electromagnetic module 702 are both connected to an external controller, and the rotation sensor 701, the electromagnetic module 702 and the external controller are all prior arts, and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0026] In actual application of this embodiment, in the initial state, the electromagnetic module 702 is in the closed state, at which time the electromagnetic module 702 is in contact with the magnetic block 703, and the support tube 4 is located at the lowest point of its moving path; while the rotating component 9 drives the rotating wheel 3 to rotate and rotate, the rotating sensor 701 monitors the number of rotations of the rotating wheel 3. When the number of rotations reaches a threshold, the rotating sensor 701 sends a signal to the external controller, and the external controller drives the electromagnetic module 702 to start. The magnetic repulsion between the electromagnetic module 702 and the magnetic block 703 drives the magnetic block 703 to rise, and drives the middle tube 5, the support tube 4 and the bottom tube 6 to rise synchronously.

[0027] It should be noted that a stopper is provided on the top of the test tube rack 2, and the stopper interferes with the moving path of the magnetic block 703, which can prevent the support tube 4 from sliding off the test tube rack 2; the distance between the stopper and the electromagnetic module 702 is the moving distance of the magnetic block 703, and is the maximum distance of the magnetic repulsion between the electromagnetic module 702 and the magnetic block 703.

[0028] like Figure 3-Figure 5 As shown, as a preferred embodiment of the present invention, an elastic member 10 is connected between the middle tube 5 and the bottom tube 6, and the middle tube 5 is connected to the bottom tube 6 through a connecting rod 11, and the connecting rod 11 is a telescopic structure.

[0029] In one case of this embodiment, the elastic limit of the elastic member 10 is less than the weight of the test tube; the elastic member 10 can be selected from Figure 3 The rubber ring shown may also be selected from other elastic structures, which will not be described in detail here; the telescopic structure is a structure formed by nesting multiple stages of pipe fittings, and in actual application, a gear rack or electric telescopic rod structure may also be used, which is not specifically limited in this embodiment.

[0030] When this embodiment is actually used, in the initial state, the distance between the middle tube 5 and the bottom tube 6 is at the minimum state, at which time the elastic member 10 is in a contracted state, and there is a gap between the bottom tube 6 and the transmission disk 8, and the electromagnetic module 702 is in a closed state; after the test tube is placed in the support tube 4, the test tube slides down along the middle tube 5 until its bottom abuts against the bottom tube 6, and then under the action of the gravity of the test tube, the test tube pushes the bottom tube 6 to continue to descend, and the elastic member 10 gradually stretches until the bottom tube 6 abuts against the transmission disk 8, and then the transmission disk 8 drives the test tube to rotate through the bottom tube 6. This method can ensure that the test tube enters the test tube rack 2 in a slow manner and is gradually driven to start rotating, which can reduce the damage to the test tube caused by collision when the test tube is placed, and can also minimize the violent shaking caused by the moment the test tube starts to rotate; the connecting rod 11 can ensure that the bottom tube 6 will not deviate from its moving path, and can accurately abut against the transmission disk 8 after the elastic member 10 is stretched.

[0031] like Figure 3-Figure 5As shown, as a preferred embodiment of the present invention, the range of the magnetic repulsion force between the electromagnetic module 702 and the magnetic block 703 is greater than the maximum deformation of the elastic member 10.

[0032] In one case of the present embodiment, the distance between the stop block and the electromagnetic module 702 is the range of action of the magnetic repulsion force between the magnetic block 703; in actual application, after the blood and anticoagulant in the test tube are shaken evenly, the magnetic repulsion force between the electromagnetic module 702 and the magnetic block 703 drives the magnetic block 703 to rise, and the elastic member 10 stretches slightly to its maximum deformation state, and then the magnetic block 703 continues to rise and drives the middle tube 5, the support tube 4 and the bottom tube 6 to rise synchronously, so as to realize the lifting of the support tube 4 and the stopping of the rotation of the bottom tube 6.

[0033] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the rotating component 9 includes: a rotating disk 901, which is rotatably mounted on the base 1, and its central axis is driven to rotate by an external driving source, and a plurality of gears 903 are rotatably mounted on the rotating disk 901, and the plurality of gears 903 are coaxially fixed on a plurality of rotating wheels 3 respectively; and a ring gear 902, which is fixed on the base 1 and is coaxially mounted with the rotating disk 901, and the plurality of gears 903 are all located inside the ring gear 902, and the plurality of gears 903 are all meshed with the ring gear 902.

[0034] In one case of this embodiment, the external driving source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can cause the rotating disk 901 to rotate. This embodiment does not make any specific limitations here.

[0035] In actual application of this embodiment, an external driving source drives the rotating disk 901 to rotate, driving the several gears 903 thereon to rotate around the central axis of the rotating disk 901. At the same time, the meshing transmission between the gear 903 and the ring gear 902 drives the gear 903 to rotate synchronously. Then, the several rotating wheels 3 can rotate while rotating, and synchronously drive the test tube to rotate while rotating, so as to achieve the shaking of blood and anticoagulant.

[0036] Working principle of the present invention: The above embodiment of the present invention provides a shaking device for venous blood specimen detection in the hematology department. When the medical staff puts the test tube into the support tube 4, the test tube slides down along the middle tube 5 until its bottom abuts against the bottom tube 6. At this time, the bottom tube 6 abuts against the transmission disk 8, and the rotating component 9 drives a plurality of rotating wheels 3 to rotate about the central axis of the base 1 and rotate at the same time. During this process, the test tube rotates synchronously and rotates by itself, so that the blood and anticoagulant in the test tube can be fully shaken and mixed; when the number of rotations of the rotating wheel 3 reaches a threshold value, it indicates that the test tube is shaken to a certain extent. It is enough. At this time, the withdrawal component 7 is started and drives the middle tube 5 to rise, then the support tube 4 rises synchronously and slides relative to the test tube rack 2, and at the same time the bottom tube 6 rises and separates from the transmission disk 8, then the bottom tube 6 stops rotating, so that the test tube stops rotating; after the support tube 4 is raised, the medical staff is reminded to take out the test tube in the support tube 4 and send it for inspection in time, and the test tube stops rotating during this process, which can avoid the test tube still rotating for a long time after being shaken, resulting in failure to send it for inspection in time, or causing violent shaking to cause red blood cells to rupture, thereby affecting the blood test results.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
