Description

Technical Field

[0001] The present application relates to the technical field of blood testing, and in particular to a coagulation testing component and a coagulation testing instrument. Background Art

[0002] Thromboelastograph (TEG) is an analyzer that monitors the coagulation process from the entire dynamic process of platelet aggregation, coagulation, fibrinolysis, etc., and is used to monitor and analyze the coagulation state of blood samples. The current monitoring methods of thromboelastographs mainly include a method of driving the cup cover with a test column to rotate and a method of driving the cup body containing the blood sample to move. As for the method of driving the cup body containing the blood sample to move, it drives the container containing the blood sample to rotate, and uses the different resistances generated by the adhesion of fibrin in the blood sample, so that the power transmitted to the hanging wire through the test column of the cup cover immersed in the blood is different, reflecting different data changes on the sensor, thereby achieving the purpose of detecting the blood coagulation process. As for the method of driving the cup cover with a test column to rotate, it uses magnetic force to pull the cup cover with a test column to rotate to stir the blood sample in the cup body, and then converts the complex biological changes that occur microscopically in the blood coagulation process into pulse signals through the code disk and signal transceiver for collection and processing into thromboelastograms, thereby achieving the purpose of detecting the blood coagulation process.

[0003] No matter which monitoring mode is designed in the current thromboelastograph, the blood sample is tested in an open state.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0054] The embodiment of the present application discloses a coagulation detection component.

[0055] See also Figure 1 as well as Figure 5 , an embodiment of a coagulation detection component provided in the embodiments of the present application includes:

[0056] A constant temperature vessel 1, a cup body 2 and a cup cover 3. The constant temperature vessel 1 is provided with a positioning groove 11 for the cup body 2 to be placed. The constant temperature vessel 1 is installed on the thermostat 100 of the coagulation detection instrument, and is used to position and install the cup body 2. At the same time, it can keep the cup body 2 at a constant temperature under the action of the heating control module of the thermostat 100. The cup body 2 is a container with an opening at one end, which is used to hold a blood sample, that is, a blood sample to be tested. The cup cover 3 is connected to the detector 200, and is provided with a test column 31 for immersing the blood sample in the cup body 2. The constant temperature vessel 1, the cup body 2 and the cup cover 3 can be designed or used based on the corresponding components in the existing coagulation detection instrument, and are not the focus of improvement in this case, so they will not be described in detail.

[0057] The present application scheme also focuses on the cup cover 4. The cup cover 4 can be arranged on the thermostatic vessel 1 to form a cover for the cup body 2, and the cup cover 4 is provided with an avoidance cavity 41 for avoiding the cup cover 3. The cup cover 4 can be connected to the detector 200, and then move together with the detector 200. When the detector 200 is controlled by the corresponding driving mechanism 400 on the coagulation detection instrument and moves until the test column 31 of the cup cover 3 is immersed in the blood sample of the cup body 2, the cup cover 4 is in a position arranged on the thermostatic vessel 1 and forms a cover for the cup body 2. In addition to the above-mentioned situations, those skilled in the art can also make appropriate changes to the layout of the cup cover 4 based on this, without limitation.

[0058] The aforementioned formation of a cover on the cup body 2 refers to the cup cover 4 at least forming a certain cover-type seal on the opening of the cup body 2, so as to achieve the purpose of reducing the evaporation of water and temperature loss of the blood sample inside the cup body 2. The structure of the cup cover 4 can be designed with reference to the conventional cover structure, for example, at least including a side circumference and a top circumference, the side circumference can be inserted into one end of the cup body with an opening, the top circumference is connected to the top of the side circumference, and is provided with a bypass opening that can avoid the cup cover 3, and the bypass opening and the inner cavity of the side circumference together constitute a bypass cavity to avoid interference with the relative movement between the cup body 2 and the cup cover 3. The way to seal the opening of the cup cover 4 and the cup body 2 can be that the top circumference of the cup cover 4 is arranged above the cup cover 3, that is, the cup cover 3 and the cup body 2 form a cover together, thereby achieving the sealing of the opening of the cup body 2, then the bypass opening of the top circumference is used to avoid the connection between the cup cover 3 and the detector 200, and the art can make appropriate changes and designs based on this, without limitation. Furthermore, the cup cover 4 of the present application can be integrally formed, that is, the top perimeter and the side perimeter are integrally connected, or the top perimeter and the side perimeter are detachably connected, or the cup cover 4 is divided into multiple assembleable modules along its own vertical center line, and multiple modules can be assembled to form the cup cover 4 when used, etc., without specific limitation.

[0059] It can be seen from the above technical solutions that the present application designs a cup cover 4 so that the cup cover 4 has an avoidance cavity 41 for avoiding the cup cover 3, so as to avoid interference with the cup cover 3. At the same time, the cup cover 4 may not be arranged on the constant temperature vessel 1, and forms a cover for the cup body 2. By designing such a cup cover 4, it can play a role in blocking the external environment during the test process, reduce the effect of water evaporation and temperature loss of the blood sample during the test process, thereby ensuring the accuracy of the test results. It solves the technical problem that water evaporation is easy to occur in the existing blood sample detection, causing the blood sample to coagulate faster and causing inaccurate test results.

[0060] The above is an embodiment of a blood coagulation detection component provided in the embodiment of the present application. The following is an embodiment of a blood coagulation detection component provided in the embodiment of the present application. For details, please refer to Figures 1 to 5 .

[0061] Based on the solution of the above embodiment 1:

[0062] Furthermore, in order to facilitate the taking and placing of the cup body 2, the cup body 2 is provided with a cup handle 21. In order to avoid the design of the cup handle 21, a notch 42 for avoiding the cup handle 21 can be provided at the bottom of the cup cover 4. Taking the composition structure of the cup cover 4 in the first embodiment as an example, the notch 42 is specifically provided at the bottom of the side wall. The shape of the notch 42 can be set to match the shape and size of the cup handle 21, such as a rectangle, etc., without limitation.

[0063] Furthermore, in order to better adapt to the structure of the cup cover 3 with the test column 31, the avoidance cavity 41 is designed to include a first cavity section 411 and a second cavity section 412. Among them, the diameter of the first cavity section 411 is greater than the diameter of the second cavity section 412, so that a step surface partially overlaps with the top surface of the cup cover 3 in the vertical direction is formed between the first cavity section 411 and the second cavity section 412. And the formed step surface is designed to have a partial overlap with the top surface of the cup cover 3, so that it can cooperate with the cup cover 3 to achieve a better covering of the cup body 2. The first cavity section 411 and the second cavity section 412 can be distributed in sequence from bottom to top or from top to bottom, and the corresponding step surface can be located above the top surface of the cup cover 3 or below the bottom surface of the cup cover 3. Taking the example that the first through cavity section 411 and the second through cavity section 412 are distributed sequentially from bottom to top, that is, the first through cavity section 411 is used to avoid the cup cover 3 and the test column 31 carried by the cup cover 3, and the second through cavity section 412 can be used to avoid the connection between the cup cover 3 and the detector 200. Taking the example of the distribution from top to bottom, the first through cavity section 411 is used to avoid the test column 31, and the second through cavity section 412 is used to avoid the cup cover 3 and the connection between the cup cover 3 and the detector 200. The width of the overlapping part can be changed and designed according to actual needs, and it will not interfere with the cup cover 3 and the test column 31. Those skilled in the art can make appropriate changes based on this without limitation.

[0064] Furthermore, on the basis of the step surface being provided in the avoidance cavity 41, the present application solution may also include the following Figure 5 Specifically, the cup cover 3 is detachably connected to the detector 200 in the vertical direction, so that the cup cover 3 can be separated from the detector 200 by force in the vertical direction, as shown in FIG. Figure 2 as well as Figure 3 As shown, the cup cover 3 is detachably connected to the corresponding connecting piece 202 on the detector 200 in the vertical direction.

[0065] In order to make better use of the step surface, the part of the step surface that overlaps with the cup cover 3 is located above the cup cover 3, so that after driving the cup cover 3 to move, the design of the overlapping part between the step surface and the cup cover 3 can be used to apply force to the cup cover 3, so as to detach the cup cover 3 from the detector 200 and complete the disassembly of the cup cover 3. The driving end of the driver 5 is connected to the cup cover 4, and is used to drive the cup cover 4 to move in the vertical direction, and drive the cup cover 4 and the connecting piece 202 to move relative to each other, so as to drive the cup cover 3 to detach from the detector 200. The cup cover 4 can be designed as a T-shape as a whole, that is, the side surround of the top surround extends out of the top of the side surround, which can provide a larger connection surface and is more convenient to connect with the driver 5.

[0066] Furthermore, the driver 5 is a linear motor module, such as a motor push rod, a screw 52 slide mechanism, etc., and of course it can also be a pneumatic push rod, a hydraulic push rod and other mechanisms without limitation.

[0067] Further, taking the linear motor module of the driver 5 as an example, it can specifically include a rotating motor 51, a movable part, a screw nut 53 and a screw 52. Among them, the output shaft of the rotating motor 51 is connected to the screw 52 for synchronous rotation, and is used to drive the screw 52 to rotate. The movable part is restricted to move in the vertical direction, the screw nut 53 is embedded in the movable part, and the screw 52 is allowed to move through, the screw nut 53 is threadedly matched with the screw 52, ​​and the cup cover 4 is connected to the movable part. The movable part is restricted to move in the vertical direction, that is, it cannot rotate, so that the rotation of the screw 52 can be converted into the linear motion of the movable part through the screw nut 53, thereby driving the cup cover 4 to move in the vertical direction.

[0068] Furthermore, the structure of the movable part includes a transmission block 54, a connection block 56 and a plurality of connection rods 55. The rotating motor 51 is vertically inverted on the detector 200, the transmission block 54 is arranged between the rotating motor 51 and the detector 200, the screw nut 53 is embedded in the transmission block 54, the connection block 56 is arranged below the transmission block 54 and connected to the transmission block 54 through a plurality of connection rods 55, an installation gap for avoiding the detector 200 is formed between the connection block 56 and the transmission block 54, and the cup cover 4 is connected to the connection block 56. Such a structural design of the movable part can be better integrated with the detector 200, such as Figure 5 The embodiment shown is integrated in the same vertical straight line direction, so that the overall structure is more compact. As for the fixing of the rotating motor 51, it can be fixed on the detector 200, for example Figure 5As shown, the rotating motor 51 is fixed on the bearing structure of the detector 200 through the motor mounting frame, or fixed on other corresponding support structures, without limitation. The bearing structure is the supporting and fixing structure used to install and fix the detection components in the detector 200, which can be appropriately changed and designed according to the actual installation and fixing needs, and the specific details are not repeated. As for the vertical movement restriction of the movable part, it can be achieved by limiting the vertical movement of the transmission block 54, or limiting the vertical movement of the connecting rod 55, or limiting the vertical movement of the connecting block 56, without specific limitation.

[0069] Further, taking the restriction of the vertical movement of the connecting rod 55 as an example, there are at least two connecting rods 55, and the detector 200 can be as follows: Figure 5 As shown, guide holes 201 for connecting rods 55 to pass through are provided on the bearing structure thereof, so that the movable part is restricted to move in the vertical direction through the cooperation between the connecting rods 55 and the guide holes 201 .

[0070] In the present application, taking the example that the driver 5 is specifically an electric push rod or a hydraulic push rod, the driver 5 can be installed vertically and inverted on the side of the detector 200, for example, it is installed and fixed on the side of the bearing structure of the detector 200, and the end of the telescopic rod of the driver 5 is connected to the cup cover 4. Of course, in order to be able to drive the cup cover 4 to move more smoothly, the driver 5 can be designed to be multiple, and relatively distributed around the vertical center line of the cup cover 4, so that multiple drivers 5 can drive the cup cover 4 to move at the same time, increase the connection points, and improve the stability of the drive. Of course, the cup cover 4 can be movably installed through a guide structure such as a guide rod, that is, the cup cover 4 itself has better movement stability after being restricted by the movement of the guide structure, so the number of drivers 5 can be designed to be one. Those skilled in the art can make adaptive modifications and changes based on these means proposed in this application without limitation.

[0071] Further, taking the present application scheme with a driver 5 as an example, in order to accurately control the movement position of the cup cover 4, a first induction switch and a second induction switch are also configured. The first induction switch is used to locate the initial position of the cup cover 4, and the second induction switch is used to locate the position of the cup cover 4 when driving the cup cover 3 to completely leave the detector 200. The first induction switch and the second induction switch can select induction switches of different induction types according to actual needs. For example, the first induction switch and the second induction switch may include a transmitter and a receiver, the transmitter transmits a light signal to the receiver, and a barrier is installed on the cup cover 4 to block the light signal. When the receiver does not receive the light signal, it means that the barrier on the cup cover 4 has moved between the transmitter and the receiver. The first induction switch and the second induction switch can output a signal to prompt the cup cover 4 to move to a predetermined position. The installation and fixation of the first induction switch and the second induction switch can be fixed on the bearing structure of the detector 200 through the corresponding switch mounting frame, or fixed at other positions on the coagulation detection instrument, without limitation.

[0072] The present application also discloses a coagulation detection instrument, including a coagulation detection component. The main structure of the coagulation detection instrument can be designed or used based on the existing coagulation detection instrument structure. The main structure can include: Figure 6 as well as Figure 7 The base 300, the driving mechanism 400 and the control module are shown. The driving mechanism 400 is a linear module, which is vertically mounted on the top of the base 300 to drive the detector 200 to move in the vertical direction. The thermostat 100 is mounted on the base 300 and is located directly below the detector 200. The structure of the detector 200 can be designed according to the detection method. If the method is to drive the cup body 2 containing the blood sample to move, the detector 200 structure can be an existing hanging wire design. At the same time, the base 300 is also equipped with a rotating mechanism for the driver 5 to rotate, so that the cup body 2 in the thermostatic vessel 1 can rotate. If the method is to drive the cup cover 3 with the test column 31 to rotate, then the detector 200 can be an existing magnetic mechanism design, using magnetic force to pull the cup cover 3 with the test column 31 to rotate to stir the blood sample in the cup body 2, and then convert the complex biological changes in the blood coagulation process into pulse signals through the code disk and the signal transceiver for collection and processing into thromboelastograms, thereby achieving the purpose of detecting the blood coagulation process. When the improved coagulation detection assembly of the present application is used in a coagulation detection instrument, the corresponding installation positions of its various components can be appropriately changed according to the actual structure of the coagulation detection instrument without limitation.

[0073] The above is a detailed introduction to a coagulation detection component and a coagulation detection instrument provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
