Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a mixing device of a platelet oscillator. Background Art

[0002] In hematology research, the aggregation and coagulation ability of platelets is an important indicator for evaluating platelet function. The platelet oscillator simulates the blood flow state in the human body and oscillates the platelet sample to evaluate its aggregation and coagulation ability. As one of the core components of the platelet oscillator, the main function of the mixing device is to ensure the uniform distribution of platelet samples during the oscillation process to avoid measurement errors caused by uneven sample distribution.

[0003] However, the mixing device of the existing platelet oscillator has limited vibration amplitude and frequency due to the limitations of the device itself, making it difficult to mix platelets, thereby greatly increasing the oscillation mixing time, resulting in low work efficiency and insufficient practicality.

[0004] In view of the above problems, the utility model proposes a mixing device for a platelet oscillator. Utility Model Content

[0005] The purpose of the utility model is to provide a mixing device for a platelet oscillator, wherein one end of a side block away from the inner wall of an oscillation disk is fixedly connected to a clamping block, the inner wall axis of the clamping block is connected to a first inclined plate and a second inclined plate, one end of the first inclined plate is axially connected to a first slider, one end of the second inclined plate is axially connected to a second slider, and a return spring is fixedly connected between the first slider and the second slider, thereby solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mixing device for a platelet oscillator, comprising a body and a support member installed at the lower end of the body, a vibration mechanism installed in the cavity of the body, an oscillation disk installed at the output end of the vibration mechanism, a protective cover provided at the upper end of the oscillation disk, a clamping assembly installed on the inner wall of the oscillation disk, a plurality of clamping assemblies provided, and arranged around the inner wall of the oscillation disk;

[0007] The clamping assembly includes a side block with one end fixedly connected to the inner wall of the oscillation plate, and the end of the side block away from the inner wall of the oscillation plate is fixedly connected to the clamping block, the inner wall axis of the clamping block is connected to the first inclined plate and the second inclined plate, one end of the first inclined plate is axially connected to the first slider, one end of the second inclined plate is axially connected to the second slider, and a return spring is fixedly connected between the first slider and the second slider.

[0008] Preferably, the clamping block is semi-cylindrical in shape and is a component made of rubber material.

[0010] Preferably, the first sliding block and the second sliding block are symmetrically distributed about the center of the clamping block, and the first sliding block and the second sliding block are both slidably connected to the inner wall of the side connecting block.

[0011] Preferably, when the return spring is in a tensioned state, the outer wall of the clamping block is recessed inward.

[0012] Preferably, the oscillation plate comprises a cover frame matching the opening of the oscillation plate, and a transverse elastic band and a longitudinal elastic band are installed on the inner wall of the cover frame.

[0013] Preferably, the transverse elastic bands and the longitudinal elastic bands are provided in multiple groups, and are staggered with each other.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model proposes a mixing device for a platelet oscillator. When the container vibrates, a force is applied to a clamping block. The outer wall of the clamping block is forced to be concave inward, driving the first inclined plate and the second inclined plate to tilt at an angle, driving the first sliding block and the second sliding block to move away from each other, thereby tightening a reset spring. Through the reaction force of the reset spring and the elasticity of the clamping block itself, the outer wall of the clamping block will reciprocately be concave and recover, thereby increasing the frequency of vibration from the side end and improving the efficiency of vibration mixing. The mixing device of the existing platelet oscillator solves the problems that, due to the limitations of the device itself, its vibration amplitude and frequency are limited, making it difficult to mix platelets, thereby greatly increasing the time for vibration mixing, low working efficiency and insufficient practicality.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 In order to solve the problems of the existing platelet oscillator mixing device, due to the limitations of the device itself, its vibration amplitude and frequency are limited, it is difficult to mix platelets, thereby greatly increasing the oscillation mixing time, low work efficiency, and insufficient practicality, the following preferred technical solutions are provided:

[0023] A mixing device for a platelet oscillator comprises a body 1 and a support member 2 installed at the lower end of the body 1, a vibration mechanism 3 is installed in the cavity of the body 1, an oscillation disk 4 is installed at the output end of the vibration mechanism 3, a protective cover 5 is arranged at the upper end of the oscillation disk 4, a clamping assembly 6 is installed on the inner wall of the oscillation disk 4, the clamping assembly 6 is provided with multiple groups, and is arranged around the inner wall of the oscillation disk 4, the clamping assembly 6 comprises a side block 61 fixedly connected to the inner wall of the oscillation disk 4 at one end, a clamping block 62 is fixedly connected to the end of the side block 61 away from the inner wall of the oscillation disk 4, the inner wall axis of the clamping block 62 is connected to a first inclined plate 63 and a second inclined plate 64, one end of the first inclined plate 63 is axially connected to a first slider 65, one end of the second inclined plate 64 is axially connected to a second slider 66, and a reset spring 67 is fixedly connected between the first slider 65 and the second slider 66.

[0024] The clamping block 62 is semi-cylindrical in shape and is a component made of rubber material. The first inclined plate 63 and the second inclined plate 64 are symmetrically distributed about the center of the clamping block 62. The first slider 65 and the second slider 66 are symmetrically distributed about the center of the clamping block 62. The first slider 65 and the second slider 66 are both slidably connected to the inner wall of the side block 61. When the return spring 67 is in a tensioned state, the outer wall of the clamping block 62 is recessed inward.

[0025] The oscillation plate 4 includes a cover frame 41 that matches the opening of the oscillation plate 4. The inner wall of the cover frame 41 is installed with transverse elastic bands 42 and longitudinal elastic bands 43. There are multiple groups of transverse elastic bands 42 and longitudinal elastic bands 43, which are staggered with each other.

[0026] Specifically, when the platelets are shaken and mixed, the container loaded with platelets is first placed in the shaking disk 4, and the vibration mechanism 3 is driven, so that the electric motor converts electrical energy into rotational kinetic energy, and then converts it into vibration of the shaking platform through the transmission structure. This is the prior art. When the container vibrates, a force will be applied to the clamping block 62, and the outer wall of the clamping block 62 is forced to be concave inward, driving the first inclined plate 63 and the second inclined plate 64 to tilt at an angle, driving the first slider 65 and the second slider 66 to move away from each other, thereby tightening the reset spring 67. Through the reaction force of the reset spring 67 and the elasticity of the clamping block 62 itself, the outer wall of the clamping block 62 will reciprocate and recover, thereby increasing the frequency of vibration from the side end, improving the efficiency of shaking and mixing, and solving the problem of the mixing device of the existing platelet oscillator. Due to the limitations of the device itself, its vibration amplitude and frequency are limited, and it is difficult to mix platelets, thereby greatly increasing the shaking and mixing time, low working efficiency, and insufficient practicality.

[0027] The transverse elastic band 42 and the longitudinal elastic band 43 on the inner wall of the cover frame 41 can buffer the upward force of the container. The force of the transverse elastic band 42 and the longitudinal elastic band 43 can not only increase the vibration frequency of the container, but also prevent the container from escaping from the clamping block 62.

[0028] To sum up: when the platelets are shaken and mixed, first place the container loaded with platelets in the shaking disk 4, drive the vibration mechanism 3 to vibrate the shaking disk 4, and when the container vibrates, it will act on the clamping block 62, and the outer wall of the clamping block 62 will be forced to be concave inward, driving the first inclined plate 63 and the second inclined plate 64 to tilt at an angle, driving the first slider 65 and the second slider 66 to move away from each other, thereby tightening the reset spring 67. Through the reaction force of the reset spring 67 and the elasticity of the clamping block 62 itself, the outer wall of the clamping block 62 will reciprocate and recover, thereby increasing the frequency of vibration from the side end and improving the efficiency of shaking and mixing. The force of the transverse elastic band 42 and the longitudinal elastic band 43 will not only increase the vibration frequency of the container, but also prevent the container from detaching from the clamping block 62.
