Description
Technical Field
[0001] This application relates to the field of coagulation testing, and more particularly to a coagulation testing device for medical samples. Background Technology
[0002] As people pay more attention to their health, more and more people regularly assess their physical condition through blood tests or store their blood for other uses.
[0003] With the storage of large quantities of blood samples, their condition needs constant monitoring, and abnormal samples must be screened out. In existing technologies, waste blood samples require personnel to sequentially assess their quality and filter out the unusable ones. However, the optimal placement angle for each blood sample varies, necessitating individual adjustments that are extremely labor-intensive and inefficient.
[0004] In existing technologies, coagulation analysis equipment is used to automatically test blood samples. Unlike conventional coagulation tests, which involve adding a coagulant to the blood sample and then using optical or magnetic bead detection, the testing of waste blood samples from toiletries requires careful consideration to prevent contamination. Magnetic bead detection is not feasible, necessitating optical detection. However, the emitted light beams used in optical detection are often insufficient for blood testing. Therefore, different types of emission light sources need to be prepared in advance to overcome the limitation of a small detection range. However, currently, preparing different types of emission light sources requires the involvement of multiple devices, increasing the size and cost of the detection apparatus and significantly increasing the difficulty of coagulation testing of blood samples.

[0037] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:
[0038] This application discloses a coagulation detection device for medical samples, comprising the following components: at least two light source emitting modules, a beam integration module, a blood sample tube, and a coagulation detection module. The connection method of each component of the coagulation detection device is as follows: The light source emitting module includes a beam emitter and a prism. The beam emitter is placed perpendicular to the prism's prism facet. The prism includes at least three prism faces; the prism facet perpendicular to the beam emitter is the incident prism facet, and the beam exiting prism facet is the exiting prism facet. The beam integration module has at least two incident areas and one exit port. The prisms of at least two light source emitting modules are placed behind the beam integration module, such that the exiting prism facet corresponds to one of the incident areas of the beam integration module. The number of incident areas is greater than or equal to the number of light source emitting modules. The beam integration module integrates the beams emitted from the exiting prism facest. The blood sample tube is positioned in front of the exit port of the beam integration module. The coagulation detection module is located to one side of the blood sample tube.
[0039] A beam is emitted by a beam emitter, and upon reaching the incident surface of a prism, it is refracted and split into beams of different wavelengths. These beams exit through the exit surface and enter a beam integration module. The beam integration module receives beams emitted from at least two prisms, integrates them, and superimposes them to form a unified beam. This unified beam is then projected into a blood sample tube through an exit port. Finally, the coagulation detection module analyzes the light parameters passing through the blood sample tube by either photographing the tube or receiving the data to determine if coagulation has occurred. Because the prism can split the beam and integrate specific regions of the split beam, the requirements for the beam emitter are reduced, and the variety of integrated beams is increased. Compared to traditional methods of creating different types of beams, this is simpler, requires less equipment, significantly reduces the size of the detection device, and simplifies coagulation detection in blood samples.

[0050] In existing technologies, with the storage of large quantities of blood samples, the condition of these samples needs to be constantly monitored, and abnormal samples need to be screened out. Currently, waste blood samples require personnel to sequentially assess their quality and filter them out. However, the optimal placement angle for each blood sample varies, necessitating individual adjustments that are extremely labor-intensive and inefficient.
[0051] In existing technologies, coagulation analysis equipment is used for automated testing of blood samples. Unlike conventional coagulation testing, which involves adding a coagulant to the blood sample and then using optical or magnetic bead detection, the testing of waste blood samples from toiletries necessitates optical detection to prevent contamination. However, optical detection typically uses a single light source with a limited spectral wavelength range, insufficient for diverse blood testing requirements. Therefore, different wavelengths of light sources need to be prepared in advance to overcome the limited detection range. However, currently, preparing different wavelengths of light sources requires the integration of multiple devices, significantly increasing the difficulty of coagulation testing of blood samples.
[0052] Based on this, this application discloses a coagulation detection device for medical samples, which reduces the difficulty of coagulation detection in blood samples.
[0053] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0054] Please see Figure 1 , Figure 2 and Figure 3 This application provides an embodiment of a coagulation detection device for medical samples, comprising:
[0055] At least two light source emission modules 1, a beam integration module 2, a blood sample tube 3, and a coagulation detection module 4;
[0056] The light source emitting module 1 includes a beam emitter 5 and a prism 6. The beam emitter 5 is placed perpendicular to the prism 6. The prism 6 includes at least 3 prisms. The prism 6 with the beam emitter 5 perpendicular to it is the incident prism, and the beam exits from it is the exit prism.
[0057] The beam integration module is provided with at least two incident areas and one exit port. At least two prisms 6 of the light source emitting modules 1 are placed on the rear side of the beam integration module so that the exit cylindrical surface of each prism 6 corresponds to one of the incident areas of the beam integration module. The number of incident areas is greater than or equal to that of the light source emitting modules 1. The beam integration module is used to integrate the beams emitted from the exit cylindrical surface of the prism 6.
[0058] The blood sample tube 3 is positioned in front of the exit port of the beam integration module;
[0059] The coagulation detection module 4 is located on one side of the blood sample tube 3.
[0060] In this embodiment, the light source emitting module 1 includes a beam emitter 5 and a prism 6. The beam emitter 5 can emit beam sets of their own wavelengths, while the prism 6 is used to split the beam sets of different wavelengths.
[0061] Furthermore, the beam emitters 5 in at least two light source emission modules 1 are different models, meaning that the types of beams are different, thus creating a wider variety of integrated beams.
[0062] In this embodiment, the beam integration module 2 is used to integrate multiple split beams into a unified beam.
[0063] In this embodiment, the coagulation detection module 4 is divided into a traditional optical detection device and an image analysis device. Since the traditional optical detection device cannot detect some special blood types, it needs to be used in conjunction with the image analysis device for image analysis detection.
[0064] In this embodiment, a light beam is emitted by the beam emitter 5. Upon reaching the incident surface of the prism 6, the beam is refracted and split into beams of different wavelengths, which then exit through the exit surface. These beams of different wavelengths enter the beam integration module. The beam integration module receives beams emitted from at least two prisms 6. These beams are integrated and superimposed to form an integrated beam, which is then projected into the blood sample tube 3 through the exit port. Finally, the coagulation detection module 4 analyzes the light parameters passed through the blood sample tube 3 by either photographing it or receiving the light parameters to determine whether coagulation has occurred. Because the prism 6 can split the light beam and integrate a specific region of the split beam, the requirements for the beam emitter 5 are reduced, and the variety of integrated beams is increased. This method is simpler than traditional methods of creating different types of beams, eliminating the need for multiple devices and significantly reducing the size of the detection device, thus simplifying the coagulation detection in blood samples.
[0065] Optionally, the light source emitting module 1 may also include a beam filtering plate 7;
[0066] The beam filtering plate 7 is placed in front of the beam exit column of the prism 6;
[0067] The beam filtering plate 7 is provided with a beam transmission area;
[0068] The beam filtering plate 7 is equipped with a displacement component.
[0069] In this embodiment, a beam filtering plate 7 is set on the exit surface of the prism 6, and the movement of the beam filtering plate 7 can accurately pass the required beam through the beam transmission area. This design can block excess beams, so that only the selected beams enter the beam integration module.
[0070] Optionally, the beam integration module includes a pyramid with at least three conical faces;
[0071] The incident region is a cone-shaped surface;
[0072] The exit points are the corresponding vertices of the three cones.
[0073] In this embodiment, the beam integration module includes a pyramid. The filtered beam enters the interior of the pyramid through the cone surface (incident area) and finally converges at the apex before exiting.
[0074] Optionally, the beam integration module also includes a first rotary motor 8;
[0075] The first rotary motor 8 is located on the bottom surface of the pyramid.
[0076] In this embodiment, the first rotary motor 8 is installed at the bottom of the pyramid, enabling the pyramid to rotate and allowing the light beam passing through the incident area to be better integrated through the adjustment of the pyramid.
[0077] Optionally, the light source emitting module 1 may also include a first focusing lens 9;
[0078] The first focusing lens 9 is located between the beam emitter 5 and the prism 6.
[0079] Optionally, the light source emitting module 1 may also include a second rotary motor 10;
[0080] The second rotary motor 10 is located on the top surface or the ground surface of the prism 6.
[0081] In this embodiment, the light source emitting module 1 further includes a first focusing lens 9, which is used to focus the light beam and project it onto the prism surface 6 more effectively, making the splitting of the prism 6 more uniform and preventing light beams of different wavelengths from mixing. Furthermore, a second rotary motor 10 is provided on the top or bottom surface of the prism 6, which allows for precise control of the beam splitting.
[0082] Optionally, the coagulation detection device also includes a light-transmitting plate 11, a beam splitter 12, and at least two second focusing lenses 13;
[0083] The optical splitter 12 includes one input fiber and at least two output fibers;
[0084] The input optical fiber is positioned in front of the light-transmitting hole of the light-transmitting plate 11, and the light-transmitting hole of the light-transmitting plate 11 corresponds to the position of the output port of the beam integration module.
[0085] The second focusing lens 13 is positioned in front of the output optical fiber.
[0086] In this embodiment, in order to increase the rate of coagulation detection, the light beam integrated by the pyramid is first selected through the light-transmitting hole on the light-transmitting plate 11 to prevent additional light beams from mixing in. At this time, the integrated light beam enters the input optical fiber and is split into at least two beams that are emitted from the output beam. Then, the beam is focused by the second focusing lens 13, which can better project the light onto the blood sample tube 3.
[0087] Optionally, the coagulation detection module 4 includes a filter lens 14 and an optical image analyzer 15;
[0088] The filter lens 14 is positioned between the blood sample tube 3 and the optical image analyzer 15.
[0089] In this embodiment, in order to prevent interference from other light beams, a filter lens 14 is provided between the blood sample tube 3 and the optical image analyzer 15. The optical image analyzer 15 can analyze the light beam passing through the blood sample tube 3 and the image of the blood sample tube 3 to obtain an analysis of whether coagulation exists.
[0090] Optionally, the coagulation testing device also includes an assembler 16;
[0091] The assembler 16 is provided with a front light incident area, a test tube area and a rear light detection area in sequence;
[0092] Blood sample tube 3 is placed in the test tube area;
[0093] The second focusing lens 13 is disposed in the front light incident area;
[0094] The filter lens 14 and the optical image analyzer 15 are located in the rear optical detection area.
[0095] In this embodiment, the main function of the assembler 16 is to prevent external light beams from affecting the detection. Therefore, the second focusing lens 13, the blood sample tube 3, the filter lens 14 and the optical image analyzer 15 are all installed inside the assembler 16, which greatly reduces the influence of external light.
[0096] Optionally, the blood sample tube 3 has a planar light-transmitting area 17 in the middle.
[0097] Traditional test tubes have cylindrical sides, which refracts light and affects its transmission. In this embodiment, the side of the blood sample test tube 3 is modified by changing a small section of the side to a flat surface, thus creating a planar light-transmitting area 17, which allows the tubing to pass through more effectively during the testing process.

They are only used to describe the relative positional relationship between the components or parts and do not specifically limit the specific installation orientation of each component or part.
[0099] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0100] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.
