Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a simple mechanism for moving a test cup cover up and down. Background Art

[0002] In a traditional thromboelastogram instrument, a test cup cover is often sleeved on a probe, and together with an angle detection module, is suspended above a test cup; the test cup cover and the cup body do not directly contact each other, but indirectly contact through a sample to be tested, and the movement of the probe is driven by the test sample and then the movement amplitude and time are detected by the angle detection module. In this structure, due to the setting of the angle detection mechanism and the torsion wire protection mechanism additionally provided to protect the torsion wire from being damaged by the pressing and pulling forces during cup-on and cup-off operations, the probe assembly is often large in size and complex in structure.

[0003] In addition, since the probe is suspended, it is required that the instrument must be placed horizontally during installation and use, otherwise the axis of the probe and the axis of the test cup deviate and do not coincide, resulting in the inability to perform the detection or inaccurate detection results.

[0004] Especially in the aspect of a fully automatic thromboelastogram instrument, all automatic cup cover up-and-down operations are completed by motors and structures, and each test component requires several more sets of motors and structures. With a large number of channels, the structure is quite complex. Therefore, a simple mechanism for moving a test cup cover up and down is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a simple mechanism for moving a test cup cover up and down to solve the problem that the current automatic cup cover up-and-down operations are all completed by motors and structures, and the structure is quite complex.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A simple mechanism for moving a test cup cover up and down includes a detachment component, and a limiting component capable of limiting and constraining is arranged on the side of the detachment component; the detachment component includes a base, a triggerable cap is arranged on the upper side of the base, and a movable probe and a sliding sleeve are arranged inside the base; the limiting component includes a mating groove, a movable limiting sliding pin is arranged inside the mating groove, and a limiting screw capable of limiting is also arranged on the side of the sliding pin.

[0008] Further, the detachment component includes a base, the cap is arranged on the upper side of the base, the probe is arranged under the cap, the sliding sleeve is movably sleeved on the side of the probe, a first spring is fixedly connected between the side of the sliding sleeve and the inner wall of the base, and a second spring is fixedly connected between the inner wall of the sliding sleeve and the side of the probe.

[0009] Further, the probe is movably installed inside the base, the sliding sleeve is movably attached to the inner wall of the base, the first spring is also movably sleeved on the side of the sliding sleeve, and the second spring is also movably sleeved on the side of the probe.

[0010] Further, the base is a cylindrical base with a "T"-shaped cross-section and an I-shaped cylindrical groove penetrating through it, the probe is a cylindrical needle body with a cross-shaped cross-section and a tapered lower side, the cap is fixedly installed with the probe by screws, and the sliding sleeve is a cross-shaped cylindrical sleeve with a convex-shaped cylindrical groove penetrating through it.

[0011] Further, the limiting component includes a mating groove, the mating groove is opened on the side of the sliding sleeve, a sliding groove is opened on the side of the base corresponding to the mating groove, a sliding pin is movably installed inside the mating groove and the sliding groove, and a limiting screw is arranged on the side of the base.

[0012] Further, the sliding pin is a "T"-shaped threaded cylindrical pin, a circular threaded groove is opened on the side of the probe, the sliding pin is threadedly installed inside the threaded groove on the side of the probe, the limiting screw is a countersunk head cylindrical screw, and circular threaded grooves penetrating through it are symmetrically opened on the base corresponding to the sliding sleeve, and the limiting screw is threadedly installed inside the threaded groove on the side of the base.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. When the upper cup cover operation is required in the present utility model, by pressing the cap downward inside the provided detachment component, the probe and the sliding sleeve can slide downward inside the base, so that the probe is inserted into the cup cover. Loosening the cap can complete the reset under the elastic supporting force of the first spring and the second spring, and the cup cover moves upward integrally with the probe to complete the upper cup cover action; when the lower cup cover operation is required, the cap moves upward under force and the base remains stationary under force, and the probe and the sliding sleeve slide upward inside the base. At this time, the cup cover is restricted by the base and will not continue to move upward, so the cup cover will be separated from the probe to complete the lower cup cover action; when the cap moves upward under force and the base is not under force, the cup cover and the probe are not separated and are lifted integrally; in this way, all actions only need to be driven by a set of motors on the robotic arm, which can reduce a set of motors for each test body component, greatly saving costs. In addition, the sliding pin and the limiting screw inside the provided limiting component can play a limiting and constraining role during the upper and lower cup cover operations to avoid relative rotational movement of the probe. At the same time, the limiting component can be quickly disassembled during later maintenance, which greatly simplifies the structure of the probe, makes the volume of the entire device much smaller and more compact, has a lower cost, and has no special requirements for the horizontal conditions of installation and use, making it more convenient for use and maintenance and more accurate for detection.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] As Figures 1 to 6 shown, a simple mechanism for moving the cup lid up and down includes a detachment component 2, and a limiting component 3 for limit constraint is arranged on the side of the detachment component 2; specifically, through the arranged detachment component 2, simple operations can be carried out when the cup lid moves up and down, greatly simplifying the structure and making the volume of the device much smaller and more compact. More specifically, through the arranged limiting component 3, it can play a role in constraint and guidance when the detachment component 2 operates to move the cup lid up and down, and can provide limits. It is also convenient for later disassembly and maintenance after disassembly.

[0027] As Figures 2 - 4 shown, the detachment component 2 includes a base 201, a cap 202 is arranged on the upper side of the base 201. The cap 202 is a convex-shaped circular block. A probe 203 is arranged on the lower side of the cap 202, and the probe 203 is movably installed inside the base 201. A sliding sleeve 204 is movably sleeved on the side of the probe 203, and the sliding sleeve 204 is movably attached to the inner wall of the base 201. A first spring 205 is fixedly connected between the side of the sliding sleeve 204 and the inner wall of the base 201, and the first spring 205 is movably sleeved on the side of the sliding sleeve 204. A second spring 206 is fixedly connected between the inner wall of the sliding sleeve 204 and the side of the probe 203, and the second spring 206 is movably sleeved on the side of the probe 203;

[0028] Specifically, as Figure 5 shown, when the arranged cap 202 is pressed downward by force, the sliding sleeve 204 and the probe 203 will slide downward along the inside of the base 201, and the probe 203 will insert into the cup lid. When the force disappears, through the arranged first spring 205 and second spring 206, the probe 203 and the sliding sleeve 204 slide along the inside of the base 201 to restore to the initial position, completing the operation of putting on the cup lid;

[0029] As Figure 6 shown, when the arranged cap 202 is lifted upward by force and the base 201 is not affected by force, the probe 203 moves upward along the inside of the sliding sleeve 204 and the base 201. At this time, the cup lid is restricted and constrained by the base 201 and will not move upward. The cup lid disengages from the side of the probe 203, completing the operation of taking off the cup lid. And when the cap 202 is lifted upward and the base 201 is not affected by force, the cup lid and the probe 203 are not disengaged and are lifted as a whole;

[0030] For the convenience of later disassembly and the constraint of the sliding of internal components, the base 201 is a cylindrical base with a "T"-shaped cross-section, and an I-shaped cylindrical groove is provided inside it and runs through it. The probe 203 is a cylindrical needle body with a cross-shaped cross-section, and the lower side is conical. The cap 202 is fixedly installed with the probe 203 through a screw. The sliding sleeve 204 is a cross-shaped cylindrical sleeve with a convex-shaped cylindrical groove running through it. The cap 202 can be disassembled from the probe 203. The structures of the sliding sleeve 204 and the probe 203 can cooperate with the first spring 205 and the second spring 206 and be supported by them.

[0031] As Figures 2 - 4 shown, the limiting component 3 includes a mating groove 301. A mating groove 301 running through it is provided on the side surface of the sliding sleeve 204. The mating groove 301 is an oval groove. A sliding groove 302 running through it is provided on the side surface of the base 201 corresponding to the position of the mating groove 301. The sliding groove 302 is an oval groove. A sliding pin 303 is movably installed inside the mating groove 301 and the sliding groove 302. A limit screw 304 is provided on the side surface of the base 201 corresponding to the position above the sliding sleeve 204. Specifically, by arranging the sliding pin 303, when operating the upper cup cover and the lower cup cover, the sliding pin 303 slides inside the mating groove 301 and the sliding groove 302 to constrain and limit the internal components of the detachment component 2. At the same time, by arranging the limit screw 304, an upper limit operation can be performed on the sliding sleeve 204.

[0032] For the convenience of subsequent disassembly and the constraint of the sliding of internal components, the sliding pin 303 is a "T"-shaped threaded cylindrical pin. A circular threaded groove is provided on the side surface of the probe 203. The sliding pin 303 is threadedly installed inside the threaded groove on the side surface of the probe 203. The limit screw 304 is a countersunk head cylindrical screw. Circular threaded grooves running through it are symmetrically provided on the base 201 corresponding to the position of the sliding sleeve 204. The limit screw 304 is threadedly installed inside the threaded groove on the side surface of the base 201. Through threaded installation, direct disassembly can be carried out during subsequent disassembly, which is convenient for subsequent maintenance operations.

[0033] In summary, when the upper cup cover operation is required, the inner cap 202 of the disengaging component 2 is pressed downward, so that the probe 203 and the sliding sleeve 204 can slide downward inside the base 201, causing the probe 203 to insert into the cup cover. Releasing the cap 202 can complete the reset under the elastic supporting force of the first spring 205 and the second spring 206, and the cup cover moves upward integrally with the probe 203 to complete the upper cup cover action; when the lower cup cover operation is required, the cap 202 moves upward under force and the base 201 remains stationary under force. The probe 203 and the sliding sleeve 204 slide upward inside the base 201. At this time, the cup cover is restricted by the base 201 and will not continue to move upward. Therefore, the cup cover will disengage from the probe 203 to complete the lower cup cover action; when the cap 202 moves upward under force and the base 201 is not under force, the cup cover and the probe 203 are not disengaged and are lifted as a whole; all these actions only need to be driven by a set of motors on the robotic arm, which can reduce a set of motors for each test body component, greatly saving costs. In addition, the sliding pin 303 and the limit screw 304 inside the limit component 3 can play a limiting and restraining role during the upper and lower cup cover operations, avoiding relative rotational movement of the probe 203. At the same time, the limit component 3 can be quickly disassembled during later maintenance, which greatly simplifies the structure of the probe 203, makes the volume of the entire device much smaller and more compact, has a lower cost, and has no special requirements for the horizontal conditions of installation and use, making it more convenient for use and maintenance and more accurate for detection.
