Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood sample shaking device. Background Art

[0002] At present, after blood collection, blood stations need to test the collected blood in accordance with the "Technical Operating Procedures for Blood Stations" to prevent blood carrying infectious viruses from entering the medical sector and causing harm to blood transfusion patients. When testing, testers usually mix the blood and anticoagulant thoroughly in the blood collection tube before testing. This places certain requirements on the operator's skills and physical strength. Especially when there are a large number of blood samples that need to be shaken, there is a risk that some blood samples cannot be fully mixed and shaken. Uneven mixing can cause coagulation or hemolysis of the blood samples, resulting in a double waste of time and materials, especially waste of blood samples.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described clearly and completely below in conjunction with specific embodiments.

[0025] like Figures 1 to 8The blood sample shaking device shown in the figure includes a housing 1, a vibration frame 2 and a driving mechanism 3. The vibration frame 2 and the driving mechanism 3 are arranged in the cavity of the housing 1. The driving mechanism 3 is fixed to the housing 1 and is movably connected to the vibration frame 2 through a driving wheel 3-2 fixed to the motor 3-1. The driving wheel 3-2 is an eccentric cam, and a first shift block 3-2-1 is provided at its distal end. One side of the first shift block 3-2-1 is a pressing portion 3-2-2. The first shift block 3-2-1 rotates upward to shift the vibration frame 2 to rotate, and the pressing portion 3-2-2 When the vibrating frame 2 is rotated downward, it can press the vibrating frame 2 downward. The vibrating frame 2 is provided with a return spring 2-5. After the first shift block 3-2-1 shifts the vibrating frame 2 to rotate horizontally, the return spring 2-5 resets the vibrating frame 2 horizontally. After the pressing part 3-2-2 presses the vibrating frame 2 downward to slide, the return spring 2-5 resets the vibrating frame 2 longitudinally. That is, the vibrating frame 2 can realize longitudinal reciprocating sliding and horizontal reciprocating swinging through the driving wheel 3-2 and the return spring 2-5. The blood sample and anticoagulant in the blood collection tube can be mixed and collided in the two-way reciprocating motion and can be quickly shaken.

[0026] The vibration frame 2 includes a bracket 2-1, a clamping airbag 2-2 and a fixing seat 2-3. The clamping airbag 2-2 is arranged on the bracket 2-1 and is provided with a plurality of test tube holes corresponding to the bracket 2-1. The bracket 2-1 includes a first clamping plate 2-1-1, a second clamping plate 2-1-2 and a lower supporting plate 2-1-3 arranged in parallel. The first clamping plate 2-1-1, the second clamping plate 2-1-2 and the lower supporting plate 2-1-3 are provided with corresponding test tube holes. The clamping airbag 2-2 is arranged between the first clamping plate 2-1-1 and the second clamping plate 2-1-2. The test tube holes thereof correspond to the test tube holes of the first clamping plate 2-1-1 and the second clamping plate 2-1-2. After the clamping airbag 2-2 is inflated, the blood collection tubes placed in the test tube holes are squeezed and clamped to prevent the blood collection tubes from being squeezed when the vibration frame 2 vibrates. The lower support plate 2-1-3 is fixed with a rotary plate 2-1-4 at the bottom, and the rotary plate 2-1-4 is provided with an integrally formed center hole 2-1-5, a second shift block 2-1-6 and a second fixing hole 2-1-7; the bracket 2-1 is arranged on the fixing seat 2-3 through the connecting shaft 2-4 and the lower pressure plate 2-6, and the return spring 2-5 is sleeved on the connecting shaft 2-4, and one end of the return spring 2-5 is clamped in the second fixing hole 2-1-7 on the bracket 2-1, and the other end is clamped on the fixing seat 2-3. After the first shift block 3-2-1 drives the bracket 2-1 to swing, the circumferential elastic force of the return spring 2-5 resets it. When the bracket 2-1 is squeezed and moved downward, the axial compression force of the return spring 2-5 resets it axially. The clamping airbag 2-2 is made of elastic material and is connected to the inflation and deflation device. When inflated, the clamping airbag 2-2 can squeeze and clamp the blood collection tubes placed on the vibration frame 2 one-on-one, preventing the blood collection tubes from colliding or shifting during shaking, ensuring safe and controllable shaking of the blood sample. The fixing base 2-3 includes a fixing plate 2-3-1, a column 2-3-2, and a connecting base 2-3-3. The column 2-3-2 is arranged between the fixing plate 2-3-1 and the connecting base 2-3-3. The fixing plate 2-3-1 is fixed to the housing 1, and the connecting base 2-3-3 is connected to the bracket 2-1 via a connecting shaft 2-4.

[0027] The driving mechanism 3 includes an electrically connected motor 3-1 and a power supply 3-3. The motor 3-1 and the power supply 3-3 are fixed on the counterweight block 1-3 in the housing 1. The driving wheel 3-2 is fixed on the shaft of the motor 3-1. The motor 3-1 can drive the installed driving wheel 3-2 to rotate.

[0028] The shell 1 includes an upper shell 1-1 and a lower shell 1-2. The upper shell 1-1 is mounted on the lower shell 1-2. The upper shell 1-1 is used to ensure that the interior of the shell 1 is clean. The upper shell 1-1 needs to be removed when in use. A counterweight 1-3 is provided in the lower shell 1-2 to ensure that the shell 1 is stable when shaken and does not move due to external force. An adsorption seat 1-4 is provided at the bottom of the shell 1. The adsorption seat 1-4 is made of rubber material and can absorb and absorb shock. A start-stop button 1-5 is provided on the outer surface of the shell 1. The start-stop button 1-5 is electrically connected to the drive mechanism 3 and the vibration frame 2. The start-stop button 1-5 is used to control the start and stop of the drive mechanism 3.
