Abstract
A bracket a thrombelastography device, and a support system are disclosed. The bracket comprises: a fixed support part (101), a movable support part (102), and a connection part (103). The connection part comprises a first fixing connection member (1031) and a second fixing connection member (1032). The first fixing connection member is fixedly connected to the fixed support part; the second fixing connection member is fixedly connected to the movable support part; the first fixing connection member is connected to the second fixing connection member in point contact fashion, such that the first fixing connection member and the second fixing connection member can rotate relative to each other; the movable support part is fixedly connected to a supported object; when driven by the supported object, the movable support part rotates relative to the fixed support part by means of the point contact between the first fixing connection member and the second fixing connection member. The thrombelastography device comprises a rotational shaft and a bracket. The rotational resistance to the supported object when it rotates can be reduced.
Core Innovation
The invention provides a bracket with a fixed support part, a movable support part, and a connection part. The connection part comprises a first fixing connection member and a second fixing connection member, wherein the first fixing connection member is fixedly connected to the fixed support part and the second fixing connection member is fixedly connected to the movable support part.
The first fixing connection member is connected to the second fixing connection member in a downward point contact fashion, so the first fixing connection member and the second fixing connection member can rotate relative to each other. The movable support part is fixedly connected to a supported object, and when driven by the supported object, the movable support part rotates relative to the fixed support part by means of the downward point contact. The downward point contact is the only point contact between the fixed support part and the movable support part, so only one friction source is generated during rotation.
The disclosure further specifies point-contact implementations, including a tapered structure with a bearing and a tapered groove, and a jewel bearing with a top cone. In addition, the fixed support part can be implemented as U-shaped and “A”-shaped frames, and the movable support part can be a regular quadrangular frame structure with a central through hole. Optional magnet arrangements are described to reduce point-contact pressure and friction, and a rotational shaft and support system operation are described in connection with generating a thrombelastogram from a rotation angle.
Claims Coverage
The independent claims cover three related inventive concepts: a bracket architecture that achieves rotation using a single downward point-contact connection between a fixed support part and a movable support part; the same bracket concept with a specific quadrangular frame movable support and a through-hole arrangement; and integration of the bracket into a thrombelastography device using a rotational shaft that drives rotation under measured blood force. Across the independent claims, the core inventive element is the downward point contact as the only point contact to constrain frictional force and enable relative rotation between the support parts.
Downward point contact as the only point contact for relative rotation
A bracket comprising a fixed support part, a movable support part, and a connection part, wherein the connection part comprises a first fixing connection member and a second fixing connection member; the first fixing connection member is fixedly connected to the fixed support part; the second fixing connection member is fixedly connected to the movable support part; the first fixing connection member is connected to the second fixing connection member downward point contact fashion such that the first fixing connection member and the second fixing connection member can rotate relative to each other; the movable support part is fixedly connected to a supported object; and when driven by the supported object, the movable support part rotates relative to the fixed support part by means of the downward point contact, the downward point contact being the only point contact between the fixed support part and the movable support part.
Regular quadrangular frame movable support with central through hole and beam connections
A bracket comprising a fixed support part, a movable support part, and a connection part, wherein the connection part comprises a first fixing connection member and a second fixing connection member; the first fixing connection member is fixedly connected to the fixed support part; the second fixing connection member is fixedly connected to the movable support part; the first fixing connection member is connected to the second fixing connection member in a downward point contact fashion such that the first fixing connection member and the second fixing connection member can rotate relative to each other; the movable support part is fixedly connected to a supported object; and when driven by the supported object, the movable support part rotates relative to the fixed support part by means of the downward point contact, the downward point contact being the only point contact between the fixed support part and the movable support part, wherein the movable support part is of a regular quadrangular frame structure having a through hole in the middle, and comprises a first crossbeam, a second crossbeam, a first longitudinal beam and a second longitudinal beam, wherein the first crossbeam is fixedly connected to the second fixing connection member; the fixed support part passes through the through hole in the movable support part, and is connected to the first crossbeam of the movable support part by means of the connection part; and the second crossbeam of the movable support part is fixedly connected to the supported object.
Thrombelastography device with rotational shaft driving point-contact bracket rotation
A thrombelastography device, comprising a rotational shaft and a bracket, wherein the bracket comprises a fixed support part, a movable support part, and a connection part, wherein the connection part comprises a first fixing connection member and a second fixing connection member; the first fixing connection member is fixedly connected to the fixed support part; the second fixing connection member is fixedly connected to the movable support part; the first fixing connection member is connected to the second fixing connection member in a downward point contact fashion such that the first fixing connection member and the second fixing connection member can rotate relative to each other; the movable support part is fixedly connected to a supported object; and when driven by the supported object, the movable support part rotates relative to the fixed support part by means of the downward point contact, the downward point contact being the only point contact between the fixed support part and the movable support part, wherein the rotational shaft which serves as the supported object is fixedly connected to the movable support part in the bracket; the rotational shaft can drive the movable support part to rotate under the driving force of the measured blood; and a fixed platform; and two longitudinal beams forming part the fixed support part, wherein the fixed platform is fixedly connected to the two longitudinal beams.
Together, the independent claims define a rotation mechanism in which a movable support part rotates relative to a fixed support part using a single downward point-contact connection that is the only point contact and thereby limits frictional contact conditions. Dependent refinements within the independent-claim scope add a regular quadrangular frame movable support with a central through hole and crossbeam/longitudinal-beam structure, and further integrate the bracket into a thrombelastography device where a rotational shaft drives rotation under the driving force of measured blood.
Stated Advantages
Reduces rotational resistance by generating only one friction source through the downward point contact being the only point contact between the fixed support part and the movable support part.
Reduces point-contact pressure and friction using optional magnet arrangements.
Documented Applications
A bracket used in a thrombelastography device to generate thrombelastogram based on a rotation angle of a movable support part relative to a fixed support part.
A support system where a supported object is driven externally to rotate the movable support part via the point contact mechanism.
