Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to an arteriovenous coagulation observation device. Background Art

[0002] Hemodialysis is a key treatment method for maintaining the lives of patients with renal failure. It removes metabolic waste, toxins and excess water from the blood through the extracorporeal circulation system. In this process, a blood pump drives blood out of the patient's body, which flows through an arterial cannula, a dialyzer, and a venous cannula in sequence before being returned to the body. As key components of the extracorporeal circulation system, the arteriovenous cannula is responsible for important functions such as bubble removal, pressure regulation, and coagulation monitoring. Because the venous cannula is in the blood concentration section, coupled with factors such as slowed blood flow and insufficient anticoagulants, the risk of coagulation is very high. Coagulation can cause a partial blockage of the pipeline at the mildest level, or a complete blockage at the worst, forcing the interruption of treatment and even endangering the patient's life.

[0003] Currently, clinical practice mainly relies on manual visual observation of arteriovenous coagulation status, but there are the following technical defects: In the prior art, coagulation monitoring of arteriovenous cuvettes during hemodialysis treatment has long relied on manual visual observation. Medical staff need to use a handheld light source to illuminate the cuvette body. The angle of illumination depends on operational experience, which can easily lead to misjudgment due to light refraction. Furthermore, there are problems with inconvenient operation and inaccurate light source positioning. Furthermore, the flashlight is inconvenient to use and easy to lose. The disordered state of the hemodialysis tubing further increases the difficulty of observation, affecting the timeliness and accuracy of coagulation judgment.

[0004] These issues severely restrict the real-time and reliability of coagulation monitoring, and there is an urgent need to develop an observation device with integrated cable management, multi-angle adjustment, and strong adaptability to improve the safety of hemodialysis treatment. To address these issues, existing technologies urgently need to be improved. Summary of the Invention

[0009] Furthermore, there are several observation ports, one of which is equipped with an observation mirror. The observation mirror includes a mirror frame and a mirror body. The mirror frame is rotatably connected to the observation frame, and the mirror body is embedded in the mirror frame. The mirror body is composed of a reflector.

[0010] Furthermore, the mounting seat is in a polygonal tubular shape, and a plurality of anti-slip rings are provided on the outer wall of the mounting seat, and the anti-slip rings are made of rubber, foam or sponge.

[0011] Furthermore, an external thread is provided on the outer wall of the adjusting column, the cross-section of the accommodating hole is circular, the inner wall of the accommodating hole is provided with an internal thread, a magnet is embedded on one end of the adjusting column, and double-sided tape is adhered to the other end of the adjusting column. A cross slot or a straight slot is provided on both ends of the adjusting column.

[0012] Furthermore, the fixing frame includes a fixing rod and two fixing plates, the two fixing plates are fixed on the observation frame, the fixing rod is fixed between the two fixing plates, and the fixing rod can be connected with the C-shaped hook.

[0013] Furthermore, the observation frame includes a top plate, a bottom plate and an intermediate body, the intermediate body is fixed between the top plate and the bottom plate, the top plate and the bottom plate are provided with corresponding placement notches, the searchlight is embedded in the intermediate body, the illumination cavity and the observation port are opened on the intermediate body, and the installation cavity is formed by the top plate, the bottom plate and the intermediate body.

[0014] Furthermore, the searchlight is provided with a plurality of evenly arranged ones, and a push switch electrically connected to the searchlight is embedded in the middle body.

[0015] Furthermore, the fixing rod is covered with a spiral strip, and the spiral strip is made of rubber or silicone.

[0016] By adopting the above technical invention, the beneficial effects of the present invention are: 1. The cable management component fixes the dialysis tubing through a C-shaped hook. Together with the adjustment column and elastic parts, it can effectively restrain and organize the tubing, avoiding the disordered state of the hemodialysis tubing, providing convenience for medical staff's operation, and improving the safety and efficiency of the treatment process.

[0017] 2. The arteriovenous kettle can be movably installed in the installation cavity. Medical staff can rotate or translate the kettle body and observe through multiple observation ports.

[0021] 6. The fixing rod of the fixing bracket is covered with a spiral strip. When it is connected with the C-shaped hook, the elastic deformation of the spiral strip and the surface friction work together to form a stable connection, which can prevent the observation angle from being offset due to external forces and collisions, ensuring that the observation component remains stably fixed at different installation angles, improving the stability and reliability of the device and extending its service life.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings to clearly and completely describe the technical inventions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0033] like Figure 1As shown, the arteriovenous coagulation observation device includes a wire management component 1 and an observation component 2. The wire management component 1 has several parts and can be installed on an object, which can be a body of a hemodialysis machine, a placement rack, etc. The observation component 2 can be installed and fixed on the wire management component 1.

[0034] like Figure 2 As shown, the cable management assembly 1 includes a mounting base 11, an adjustment column 12, an elastic member 13, and a cable management head 14. The mounting base 11 defines a receiving hole 101, and the adjustment column 12 is positioned within the receiving hole 101. The cable management head 14 includes a clamping base 14a and a C-shaped hook 14b that are interconnected. The cable management head 14 is positioned within the receiving hole 101 and engages with the adjustment column 12, while the C-shaped hook 14b extends out of the receiving hole 101. The elastic member 13 is a rubber strip, a silicone strip, or a spring. The elastic member 13 is positioned within the receiving hole 101, and its two ends respectively contact the clamping base 14a and the adjustment column 12.

[0035] like Figure 3 As shown, the observation assembly 2 includes a fixing frame 21, an observation frame 22 and a searchlight 23. The fixing frame 21 is connected to the observation frame 22. The fixing frame 21 can be connected to at least one C-shaped hook 14b. The observation frame 22 is provided with a mounting cavity 201, an irradiation cavity 202 and at least one observation port 203. The irradiation cavity 202 and the observation port 203 are both connected to the mounting cavity 201. The searchlight 23 is embedded in the irradiation cavity 202. The arteriovenous pot can be movably installed in the mounting cavity 201. The light emitted by the searchlight 23 can pass through the arteriovenous pot filled with blood.

[0036] The cable management assembly 1 is a modular structure for securing and organizing hemodialysis tubing. Specifically, it utilizes a mounting base 11 with a rotatable C-shaped hook 14b, whose opening is sized to constrain the hemodialysis tubing. An adjustment column 12, a columnar component supporting the cable management head 14, is assembled to the mounting base 11 using a threaded fit.

[0037] The observation component 2 is an integrated module for carrying the arteriovenous pot and realizing optical detection. Specifically, a cavity structure with multiple light-transmitting ports can be used to realize multi-angle observation. The mounting cavity 201 is used to accommodate the chamber structure of the arteriovenous pot. Specifically, a semi-open design can be used to realize the stable placement of the pot body. The elastic member 13 is a flexible structural member with elastic deformation ability. Specifically, it can be realized by a rubber strip, a silicone strip or a spring, and generates a reverse force through its own compression. The holder 14a is a supporting structure in the cable management head 14 that contacts the elastic member 13. Specifically, it can be made of hard plastic or metal, and is used to transmit the reaction force of the elastic member 13 to the adjustment column 12.

[0038] The cable management component 1 fixes the dialysis tubing through the C-shaped hook 14b, and the threaded structure of the adjustment column 12 realizes assembly with the mounting seat 11. The elastic member 13 generates elastic force due to deformation to support the cable management head 14. The observation component 2 is connected to the C-shaped hook 14b through the fixing frame 21, which can fix the observation component 2 and facilitate the placement of the arteriovenous pot. After the arteriovenous pot is placed in the installation cavity 201, the searchlight 23 is turned on, and the light of the searchlight 23 enters the installation cavity 201 through the irradiation cavity 202, and forms a transmission light path after penetrating the arteriovenous pot. Medical staff can observe the light transmittance state of the blood in the pot body through the observation port 203. The setting of multiple observation ports 203 allows light to penetrate the pot body from different angles. The semi-open structure of the installation cavity 201 allows medical staff to rotate or translate the pot body, and cooperate with the observation ports 203 in different positions to achieve full-angle coverage observation.

[0039] The fixed frame 21 comprises a fixed rod 21a and two fixed plates 21b. The two fixed plates 21b are fixed to the observation frame 22. The fixed rod 21a is fixed between the two fixed plates 21b. The fixed rod 21a is coated with a spiral strip 21c made of rubber or silicone. The fixed rod 21a can be engaged with the C-shaped hook 14b. The fixed rod 21a is a rod-shaped component connected between the two fixed plates 21b. Specifically, it can be implemented as a metal rod or a plastic rod, which is used to form a multi-point contact connection with the C-shaped hook 14b. The fixed plates 21b are plate-shaped support components installed on both sides of the observation frame 22. Specifically, they can be implemented as stamped metal plates or injection-molded plastic plates, providing a bilateral fixing base for the fixed rod 21a. The C-shaped hook 14b has an open, arc-shaped engaging component. Specifically, it can be made of elastic metal sheet or engineering plastic, which is used to form a removable connection with the fixed rod 21a through elastic deformation. The spiral strip 21c is a strip-like structure spirally wound around the outer surface of the fixing rod 21a. Specifically, it can be made of rubber or silicone material through injection molding or coating processes. The pitch of the spiral strip 21c can be uniform or uneven. The surface texture of the spiral strip 21c contacts the C-shaped hook 14b, increasing the contact area and friction, preventing relative slip between the fixing rod 21a and the C-shaped hook 14b.

[0040] Specifically, two fixed plates 21b are fixed parallel to both sides of the observation frame 22, and the fixed rod 21a spans horizontally between the two fixed plates 21b to form a rigid support frame. When the open end of the C-shaped hook 14b contacts the fixed rod 21a, the elastic deformation of the C-shaped hook 14b enables it to be quickly inserted into or removed from the fixed rod 21a, thereby achieving rapid assembly and disassembly between the observation component 2 and the cable management component 1. When the fixed rod 21a is inserted into the C-shaped hook 14b, the raised portion of the spiral strip 21c comes into contact with the inner wall of the C-shaped hook 14b. Due to the pitch design of the spiral strip 21c, it forms multiple points of contact in the axial direction and a continuous friction surface in the circumferential direction. When an external force attempts to separate the fixed rod 21a from the C-shaped hook 14b, the rubber or silicone material of the spiral strip 21c generates a reverse force due to elastic compression, and the friction coefficient increases with increasing pressure, thereby forming a self-locking effect. In addition, the elastic recovery properties of the spiral strip 21c can compensate for the material wear gap caused by long-term use.

[0041] Through the above-mentioned arrangement, a stable connection between the observation component 2 and the wire management component 1 is achieved, preventing the observation angle from being offset due to factors such as external force collision. The contact interface between the fixed rod 21a and the C-shaped hook 14b forms an adaptively adjustable friction locking mechanism to ensure that the observation component 2 remains stably fixed at different installation angles. The clamping method of the C-shaped hook 14b and the fixed rod 21a allows medical staff to complete position fine-tuning with one hand, avoiding the risk of misjudgment of coagulation due to delayed tool operation. The present invention uses the dual effects of the structure and material of the spiral strip 21c to achieve stable clamping by utilizing the synergistic effect of elastic deformation and surface friction without changing the opening size of the hook 14b. Its structure is simpler, the cost is lower, and it is also more convenient to assemble.

[0042] like Figure 4 and Figure 5 As shown, the cable management assembly 1 includes a mounting rail 3 or mounting plate 4, both of which can be secured to the hemodialysis instrument or other support via adhesive or fasteners. The mounting rail 3 or mounting plate 4 is used to mount and secure the cable management assembly 1, allowing for flexible adjustment of its position while maintaining stable stability. The mounting rail 3 or mounting plate 4 is made of rubber, silicone, plastic, or metal.

[0043] like Figure 4 As shown, the mounting rail 3 is wavy and has a mounting groove 301 that cooperates with the mounting seat 11. The mounting rail 3 can be made of elastic material molded or metal stamped. The wavy structure forms multiple peaks and troughs to form a vertical height difference. Therefore, when multiple cable management assemblies 1 are fixed to the mounting rail 3, two adjacent cable management assemblies 1 can be kept at the same height or at different heights.

[0044] like Figure 5 As shown, the mounting plate 4 is provided with a plurality of mounting holes 401 arranged horizontally and vertically. The mounting plate 4 can be manufactured using an injection molding process or mechanical drilling. The horizontal and vertical mounting holes 401 form a matrix of positioning points, which can be used to achieve discrete position adjustment of the cable management assembly 1 by selecting different hole positions. The mounting base 11 is inserted into different hole positions to achieve vertical or horizontal positioning of the cable management assembly 1.

[0045] like Figure 6 As shown, three observation ports 203 are provided. One observation port 203 houses an observation mirror 24. The observation mirror 24 comprises a frame 24a and a body 24b. The frame 24a is rotatably connected to the observation frame 22, and the body 24b is embedded in the frame 24a. The body 24b is composed of a reflector. The term "several observation ports 203" refers to the arrangement of multiple observation channels along the circumference of the observation frame 22. Specifically, this can be achieved by adopting a circular array arrangement, with each observation port 203 corresponding to an observation path at a different angle. The observation mirror 24 can be implemented by combining a hinged metal bracket and a plane mirror, with the frame 24a providing freedom of angle adjustment. The body 24b being composed of a reflector refers to the use of a high-reflectivity optical material, specifically silver-coated glass or a polished metal mirror, to ensure efficient light reflection.

[0046] Specifically, three observation ports 203 form a circular observation channel, with a rotatable reflector assembly within each channel. When the searchlight 23 beam enters the illumination chamber 202, it is reflected directionally by observation mirrors 24 at different locations. The reflection angle is adjusted by the rotating mechanism of the mirror holder 24a. During operation, the mirror holder 24a is rotated to align the reflector with the observation area of ​​the arteriovenous chamber. The reflectors of the observation ports 203 can be adjusted independently, eliminating blind spots caused by a single observation angle.

[0047] The observation assembly 2 includes a fixed frame 21, an observation frame 22, and a searchlight 23. The observation frame 22 comprises a top plate 22a, a bottom plate 22c, and an intermediate body 22b. The intermediate body 22b is fixed between the top and bottom plates 22a and 22c. The top and bottom plates 22a and 22c are provided with corresponding placement notches 204. The searchlight 23 is embedded in the intermediate body 22b. An illumination cavity 202 and an observation port 203 are defined in the intermediate body 22b. The installation cavity 201 is formed by the top and bottom plates 22a and 22c, respectively. The top and bottom plates 22a and 22c are plate-like structures located at the top and bottom of the observation frame 22, respectively, and cooperate with the intermediate body 22b to define the installation position of the arteriovenous pot. The intermediate body 22b is a supporting structure connecting the top and bottom plates 22a and 22c. It internally defines the illumination cavity 202 and the observation port 203 to enable directional light penetration. The placement notch 204 is an arc-shaped groove opened on the edge of the top plate 22a and the bottom plate 22c, which is used to accommodate the arteriovenous pot and allow it to rotate circumferentially to adjust the observation angle.

[0048] Specifically, the placement notches 204 of the top plate 22a and the bottom plate 22c are symmetrically designed to form corresponding upper and lower clamping surfaces. When the arteriovenous pot is inserted into the installation cavity 201 along the notch, its outer wall contacts the inner edge of the notch and is fixed in place, allowing medical staff to manually rotate the pot body to adjust the observation angle. The middle body 22b focuses the light of the searchlight 23 through the irradiation cavity 202 that penetrates and projects it onto the arteriovenous pot area, avoiding light scattering caused by light source offset. The observation port 203 is opened on the side of the middle body 22b and is connected to the irradiation cavity 202 through the cavity, forming an observation path with a fixed angle; and there are multiple observation ports 203, which facilitate medical staff to observe from multiple angles; and medical staff can also directly observe the light transmittance of the blood through the observation mirror 24.

[0049] The arc-shaped design of the notch 204 allows the body of the bottle to be adaptively clamped within a certain diameter range, and rotational adjustment enables multi-angle observation. The searchlight 23 integrated into the intermediate body 22b is directly aimed at the center of the mounting cavity 201, allowing light to penetrate the cross-section of the body and illuminate the blood inside the body. The semi-open structure of the notch 204 and the mounting cavity 201 allows medical personnel to manually rotate the body to the optimal observation angle, eliminating blind spots caused by the curvature of the body surface or the location of the internal blood clot. The searchlight 23 integrated into the intermediate body 22b and the illumination cavity 202 form a directional light path, ensuring that light penetrates the blood layer of the body, improving the accuracy of the coagulation status judgment.

[0050] Several searchlights 23 are evenly spaced, and a push-button switch electrically connected to the searchlights 23 is embedded in the middle body 22b. Multiple searchlights 23 are evenly spaced or symmetrically distributed within the observation assembly 2, and can be arranged in a circular array or matrix configuration. Light sources at different locations create multi-angle projections. The push-button switch can be implemented as a microswitch or membrane switch, with its contacts forming a series control relationship with the circuitry of the searchlights 23.

[0051] Specifically, when the arteriovenous kettle is placed in the installation cavity 201, the medical staff can choose to turn on the searchlight 23 by pressing the switch. Multiple evenly distributed light sources project light onto the kettle body. The searchlight 23 located on the top of the observation frame 22 can penetrate the upper area of ​​the kettle body, and the side light source can illuminate the blood flow path in the middle of the kettle body. The spatial coverage of the light path is achieved by the distribution of multiple light sources. At the same time, the integrated press switch replaces the traditional continuous hand-held operation, avoiding the problem of difficulty in finding the light source. The present application can effectively eliminate the visual blind spots caused by the limited angle of the light source during the coagulation observation of the arteriovenous kettle, so that the kettle body can obtain multi-directional light penetration. Medical staff can achieve comprehensive observation of the coagulation status without adjusting the structure of the device.

[0052] like Figure 7As shown, the mounting base 11 is a polygonal tubular shape. Several anti-slip rings 15 can be added to the outer wall of the mounting base 11. These anti-slip rings 15 are made of rubber, foam, or sponge. Specifically, the polygonal tubular shape can be realized as a regular hexagon or square structure. The symmetry and regularity of the geometric shape increase the contact area with the mounting rail 3 or mounting plate 4. The anti-slip rings 15 are annular protrusions surrounding the outer wall of the mounting base 11. They can be made of a rubber ring with a concave-convex surface. They generate increased friction with the contact surface through elastic deformation.

[0053] Specifically, the polygonal tubular structure of mounting base 11 allows multiple flat surfaces to form multi-point contact with the curved surface of mounting groove 301 when inserted into mounting groove 301 of wavy mounting rail 3. This, combined with the anti-slip ring 15, limits circumferential displacement of mounting base 11. When mounting base 11 is inserted into mounting hole 401 of mounting plate 4, the polygonal tubular edge forms surface contact with the inner wall of mounting hole 401, preventing mounting base 11 from rotating within the hole. When anti-slip ring 15 on the outer wall of mounting base 11 contacts an object's surface, the elastic deformation of the rubber material fills microscopic gaps on the surface, generating static friction and thus creating a stable contact state.

[0054] like Figure 2 and Figure 8 As shown, the outer wall of the adjusting column 12 is provided with an external thread, the cross section of the receiving hole 101 is circular, the inner wall of the receiving hole 101 is provided with an internal thread, a magnet 16 is embedded on one end of the adjusting column 12, and a double-sided tape 17 is bonded to the other end of the adjusting column 12. A cross slot or a straight slot is provided on both ends of the adjusting column 12. The external thread and the internal thread are engaged with each other to realize the movable and detachable connection between the adjusting column 12 and the mounting seat 11. The magnet 16 can be specifically implemented by a neodymium iron boron magnet 16 or a ferrite magnet 16, which generates an adsorption force by contact with the metal surface to achieve rapid fixation. The double-sided tape 17 is a layer of sticky material covering the other end of the adjusting column 12, which can be implemented by using double-sided tape 17 and is adapted to non-metallic surface objects by bonding. The cross slot or the straight slot is provided at the tool matching slots at both ends of the adjusting column 12, and the rotation operation is realized by matching the screwdriver tool, so that the adjusting column 12 can be screwed in and out.

[0055] Specifically, when mounting base 11 is to be secured to an object with a metal surface, adjustment post 12 is first rotated with a tool to unscrew the end of magnet 16 along the internal threads of receiving hole 101, and then magnet 16 is attracted to a predetermined position on the object. If the target surface is a non-metallic material, adjustment post 12 is unscrewed from mounting base 11 with a tool, and then its end is adjusted so that the end of double-sided tape 17 faces outward and extends partially out of receiving hole 101. Finally, double-sided tape 17 is adhered to the surface of the object to achieve a fixed installation of mounting base 11.

[0056] This arrangement ensures stable and secure installation of the cable management assembly 1 in a variety of installation scenarios. Its dual-mode magnetic and adhesive fixing mechanism covers a variety of surfaces, including metal, plastic, and glass. The threaded connection between the adjustment column 12 and the mounting base 11 allows for both replacement and adjustment of the adjustment column 12, while also ensuring stable installation. The differentiated fixing design at each end of the adjustment column 12 significantly expands the device's application scenarios, making it suitable for installation in a variety of environments, including medical equipment, walls, and metal brackets.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the present invention should be included in the protection scope of the present invention.
