Description

Technical Field

[0001] This utility model relates to the field of medical testing device technology, specifically a multifunctional cardiovascular internal medicine testing instrument. Background Technology

[0002] With the increasing incidence of cardiovascular diseases, accurate and rapid heart rate detection is particularly important in clinical diagnosis and daily health monitoring. Currently, most finger-clip pulse oximeters or heart rate monitors commonly used in cardiology have a single-finger clamping structure, relying on the elastic deformation of a spring plate to provide clamping force.

[0003] However, existing single-finger clamping structures can only detect single-point data. For some patients with arrhythmia or weak peripheral circulation, single-finger detection data may have errors. Doctors often need to change fingers and take multiple measurements to obtain an average value, which is cumbersome and can easily cause patient anxiety. Secondly, existing finger clamping detectors lack a structure that adapts to desktops or fixed surfaces. When medical staff operate with both hands (such as recording data or comforting patients), the detector is prone to rolling or falling on the table, causing damage. Furthermore, the inner sensor area of ​​the finger clamping detector is in constant contact with skin sweat and dirt, which can easily breed bacteria. The current cleaning method is mostly to manually wipe the inside of the sensor groove. Due to the narrow groove, wiping is inconvenient and difficult to clean thoroughly, posing a risk of cross-infection. In addition, existing detectors do not apply uniform clamping force to fingers of different thicknesses. Too tight a grip causes patient discomfort, while too loose a grip affects the accuracy of photoplethysmography signal acquisition.

[0004] Therefore, how to design a detector that can perform simultaneous or comparative detection of two fingers, has multi-scenario support functions, facilitates deep cleaning, and can adaptively fit the finger has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional cardiovascular medicine testing instrument, which has the advantages of high detection accuracy, applicability to different finger sizes, dual-mode support for both portable and desktop use, and easy cleaning and maintenance of the sensor, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional cardiovascular medicine testing instrument includes a U-shaped block, a controller and a battery disposed on the side wall of the U-shaped block, a first fixing block fixed to the inner wall of the recess of the U-shaped block, a drive component disposed on the first fixing block, a detection component transmittedly connected to the drive component, a support mechanism disposed at the lower end of the U-shaped block, a cleaning mechanism disposed at the upper end of the U-shaped block, and a horizontal plate fixed to the side wall of the first fixing block. The detection component includes a test block connected to the drive component, and a heart rate detection mechanism is installed on the test block; The horizontal plate is used to support the finger to be tested; The battery is electrically connected to the controller and drive assembly respectively, and the controller is controlled by the drive assembly.

[0007] Preferably, the drive assembly includes hinge seats fixed to the upper and lower ends of the first fixed block, and electric cylinders hinged to the hinge seats. The two electric cylinders are symmetrically arranged about the first fixed block, and the electric cylinders are electrically connected to the controller. The drive assembly also includes a second movable block fixed to the output shaft of the electric cylinder, a connecting block hinged to the second movable block, and an arc-shaped block fixed to the side wall of the connecting block. The inner wall of the arc-shaped block is fixedly connected to the test block.

[0008] It is worth noting that using electric cylinders as the power source instead of traditional torsion springs or springs allows for precise adjustment of the clamping force and displacement of the test block on the horizontal plate via a controller. This ensures the appropriate pressure required for photoplethysmography signal acquisition while avoiding injury to the patient's fingers. The two electric cylinders are symmetrically arranged and drive the upper and lower test blocks respectively, enabling simultaneous clamping on both sides, ensuring uniform force on the fingers, and improving the stability and repeatability of the detection signal.

[0009] Preferably, the drive assembly further includes a second fixed block fixed to the side wall of the first fixed block and a first movable block rotatably mounted on the second fixed block, wherein the side wall of the first movable block is fixed to the outer side wall of the arc-shaped block.

[0010] It is worth noting that by adding a second fixed block that hinges to the first movable block, a stable pivot point is provided for the swing of the arc-shaped block. This structure restricts the movement trajectory of the test block to always be an arc swing around the hinge point of the first movable block, ensuring that the heart rate detection mechanism on the inner wall of the test block can fit against the finger skin at a preset optimal angle, preventing optical path leakage or signal loss due to movement deviation.

[0011] Preferably, there are two test blocks, which are symmetrical about the first fixed block.

[0012] It is worth noting that the two symmetrically arranged test blocks correspond to the upper and lower sides of the finger, respectively. In actual testing, the controller can simultaneously collect heart rate sensor data from both sides and perform comparative analysis. If the signal from one side is weak due to finger hair, excessive keratin, or misalignment, the system can automatically switch to the side with the stronger signal for reading, improving the success rate of the test and the reliability of the data.

[0013] Preferably, the heart rate detection mechanism includes a first heart rate sensor, a second heart rate sensor, and a third heart rate sensor fixed to the recess of the test block, and the first heart rate sensor, the second heart rate sensor, and the third heart rate sensor are all electrically connected to the controller.

[0014] It is worth noting that three heart rate sensors are arranged at different positions within the recessed area of ​​a single test block, forming a miniature array detection area. When a finger is placed on the horizontal plate, regardless of whether the finger is slightly to the left or right, at least two sensors are located at the optimal sensing position of the digital artery, achieving adaptive alignment. This reduces the requirement for precise finger placement by the patient and improves the user experience.

[0015] Preferably, the support mechanism includes a first fixed cylinder fixed to the middle of the lower end of the U-shaped block, two support blocks fixed to the lower end of the U-shaped block, and a base assembly detachably fitted below the U-shaped block; the base assembly includes a bottom block and a first fixed post fixed to the upper end of the bottom block, the outer peripheral wall of the first fixed post fitting snugly against the inner wall of the first fixed cylinder; the two support blocks are symmetrical about the first fixed cylinder, the lower end face of the support block is above the upper end face of the bottom block, and the lower end face of the first fixed cylinder is above the lower end face of the support block; the lower end faces of the two support blocks are in the same horizontal plane, and when the base assembly is removed from below the U-shaped block, the two support blocks jointly support the bearing plane and restrict the circumferential rotation of the entire machine.

[0016] It is worth noting that the support mechanism achieves the switching between two usage modes through a height difference design. When the first fixing post of the base assembly is inserted into the first fixing cylinder, the support mechanism can rotate relative to the base assembly; when fixed use is required, simply pull out the base assembly, at which point the two elongated support blocks directly contact the tabletop, forming a two-point line support.

[0017] Preferably, the cleaning mechanism includes a second fixed column fixed to the upper end of the U-shaped block, a rotating cylinder rotatably mounted on the second fixed column, a first groove opened at the upper end of the rotating cylinder, a first cleaning sponge tube fixed to the inner wall of the first groove, a second fixed cylinder through-connected to the side wall of the rotating cylinder, a second groove opened at one end of the second fixed cylinder, and a second cleaning sponge tube fixed to the inner wall of the second groove.

[0018] It is worth noting that the cleaning mechanism is integrated into the top of the device, eliminating the need for additional storage of cleaning tools. The first cleaning sponge can be filled with alcohol for wiping and disinfecting the patient's fingers; the second cleaning sponge is located on the side wall, its size matching the sensor area in the recessed part of the test block. Medical staff simply insert the test block into the second cleaning sponge and rotate it to efficiently clean the first, second, and third heart rate sensors, solving the problem of cleaning sensors in narrow recesses.

[0019] Preferably, grooves are provided on both sides of the horizontal plate, and a fourth heart rate sensor is fixedly connected to the inner wall of the groove. The fourth heart rate sensor is electrically connected to the controller. Rubber blocks are fixedly connected to both the upper and lower ends of the horizontal plate. Two sets of symmetrically arranged limiting strips are fixedly connected to both the upper and lower ends of the horizontal plate. A wiping frame is slidably fitted on the outer peripheral wall of the horizontal plate. Multiple third grooves are provided through the wiping frame. The two end faces of the wiping frame are respectively abutted against the two adjacent ends of the two limiting strips at the same height. When the wiping frame slides along the outer peripheral wall of the horizontal plate, the inner wall of the wiping frame forms a wiping fit with the surface of the fourth heart rate sensor.

[0020] It is worth noting that a fourth heart rate sensor is added to the side of the horizontal plate, enabling the device to support not only finger-clamp transmission detection (held from above and below) but also side-mounted reflection detection. When patients cannot perform transmission detection due to nail polish or thick calluses, they can place the side of their finger against the groove on the side of the horizontal plate, and data will be obtained through the fourth heart rate sensor. In addition, the wiping frame is constrained by a limiting strip, and the flexible material of its inner wall can be used to scrape and clean stains on the surface of the horizontal plate and the window of the fourth heart rate sensor simply by pushing and pulling the wiping frame, making operation extremely convenient.

[0021] Preferably, rubber cylinders are fixed to both the upper and lower ends of the horizontal plate; when the output shaft of the electric cylinder extends and drives the test block to move towards the horizontal plate, the first movable block presses against the rubber cylinder to form a contact buffer.

[0022] It is worth noting that the rubber cylinder serves a dual purpose: mechanical limiting and buffering / noise reduction. When the controller outputs an excessively large extension command due to an unexpected malfunction, the first moving block will preferentially impact the rubber cylinder rather than rigidly impact the horizontal plate, protecting the electric cylinder lead screw and internal precision sensors, extending the equipment's lifespan, and reducing mechanical noise during operation, thus providing patients with a quieter medical experience.

[0023] Preferably, the two grooves are symmetrical about the rubber cylinder.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model replaces the traditional spring clamping by setting a symmetrical arc-shaped block structure driven by an electric cylinder, which solves the problems of uncontrollable clamping force, finger discomfort or unstable signal of traditional detectors, realizes precise adaptive adjustment of the clamping force, and improves detection comfort and data accuracy. 2. This utility model adds a fourth heart rate sensor in the groove on the side of the horizontal plate and works with the heart rate detection mechanism on the upper and lower sides of the horizontal plate to realize a dual detection mode of transmission and reflection, which solves the problem that some special finger conditions (such as onychomycosis and thick calluses) cannot be detected, and expands the range of people to whom the device is applicable. 3. By setting up a support mechanism with a first fixed cylinder and a support block, this utility model solves the problems of inconvenience in switching between handheld and desktop placement scenarios and easy rolling, and realizes the quick switching between two modes of base fixing and anti-roll support, thereby improving the environmental adaptability of the equipment. 4. This utility model solves the problems of difficult cleaning of narrow areas of sensors and inconvenient finger disinfection by integrating a cleaning mechanism on the top and a sliding wiping frame on the horizontal plate. It can complete finger skin disinfection and deep cleaning of sensors without the need for external tools, effectively preventing cross-infection. Attached Figure Description

[0028] To address the issues of limited heart rate detection modes, uncontrollable clamping force, poor stability on desktops, and inconvenient sensor cleaning in existing technologies, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1 to 8 .

The two electric cylinders 11 are symmetrically arranged about the first fixed block 9, and the electric cylinders 11 are electrically connected to the controller 2. The driving assembly also includes a second movable block 17 fixed to the output shaft of the electric cylinder 11, a connecting block 16 hinged to the second movable block 17, and an arc-shaped block 14 fixed to the side wall of the connecting block 16.

[0031] In this embodiment, specifically, the driving component further includes a second fixed block 12 fixed to the side wall of the first fixed block 9 and a first movable block 13 rotatably mounted on the second fixed block 12, wherein the side wall of the first movable block 13 is fixed to the outer side wall of the arc-shaped block 14.

[0032] In this embodiment, specifically, two test blocks 15 are provided, and the two test blocks 15 are symmetrical about the first fixed block 9.

[0033] In this embodiment, specifically, the heart rate detection mechanism includes a first heart rate sensor 20, a second heart rate sensor 21, and a third heart rate sensor 22 fixed to the recess of the test block 15.

[0034] In this embodiment, specifically, the support mechanism includes a first fixed cylinder 4 fixed to the middle of the lower end of the U-shaped block 1, two support blocks 7 fixed to the lower end of the U-shaped block 1, and a base assembly detachably fitted below the U-shaped block 1; the base assembly includes a bottom block 5 and a first fixed post 6 fixed to the upper end of the bottom block 5, the outer peripheral wall of the first fixed post 6 fitting against the inner wall of the first fixed cylinder 4; the two support blocks 7 are symmetrical about the first fixed cylinder 4, the lower end face of the support block 7 is above the upper end face of the bottom block 5, and the lower end face of the first fixed cylinder 4 is above the lower end face of the support block 7; the lower end faces of the two support blocks 7 are in the same horizontal plane, and when the base assembly is removed from below the U-shaped block 1, the two support blocks 7 jointly support the bearing plane and restrict the circumferential rotation of the whole machine.

[0035] In this embodiment, specifically, the cleaning mechanism 8 includes a second fixed post 801 fixed to the upper end of the U-shaped block 1, a rotating cylinder 802 rotatably mounted on the second fixed post 801, a first groove 803 opened at the upper end of the rotating cylinder 802, a first cleaning sponge cylinder 804 fixed to the inner wall of the first groove 803, a second fixed cylinder 805 through-fixed to the side wall of the rotating cylinder 802, a second groove 806 opened at one end of the second fixed cylinder 805, and a second cleaning sponge cylinder 807 fixed to the inner wall of the second groove 806.

[0036] In this embodiment, specifically, grooves 23 are provided on both sides of the horizontal plate 18, and a fourth heart rate sensor 24 is fixedly connected to the inner wall of the groove 23. The fourth heart rate sensor 24 is electrically connected to the controller 2. Rubber blocks 19 are fixedly connected to both the upper and lower ends of the horizontal plate 18. Two sets of symmetrically arranged limiting strips 25 are fixedly connected to both the upper and lower ends of the horizontal plate 18. A wiping frame 26 is slidably fitted on the outer peripheral wall of the horizontal plate 18. Multiple third grooves 27 are provided through the wiping frame 26. The two end faces of the wiping frame 26 are respectively attached to the ends of the two limiting strips 25 at the same height that are close to each other. When the wiping frame 26 slides along the outer peripheral wall of the horizontal plate 18, the inner wall of the wiping frame 26 forms a wiping fit with the surface of the fourth heart rate sensor 24.

[0037] In this embodiment, specifically, rubber cylinders 28 are fixed to both the upper and lower ends of the horizontal plate 18; when the output shaft of the electric cylinder 11 extends and drives the test block 15 to move toward the horizontal plate 18, the first movable block 13 presses against the rubber cylinder 28 to form a contact buffer.

[0038] In this embodiment, specifically, the two grooves 23 are symmetrical about the rubber cylinder 28.

[0039] Working principle: During use, medical staff select the support mode according to the usage scenario. If frequent adjustments to the device orientation are required, the first fixing post 6 of the base assembly is inserted into the first fixing cylinder 4. At this time, the first fixing cylinder 4 and the first fixing post 6 form a rotating pair, allowing the entire machine to rotate flexibly around the base assembly, facilitating operation by medical staff at different angles. If the device needs to be fixedly placed on the nurse station desktop or tabletop, the bottom block 5 is pulled out. At this time, the two elongated support blocks 7 directly contact the desktop, forming a stable anti-roll fixing structure using the mechanical properties of two-point support, preventing the U-shaped block 1 from accidentally rolling or slipping on the flat surface. Before testing, medical staff can rotate the rotating cylinder 802 in the cleaning mechanism 8 and insert the patient's fingers into the first cleaning sponge cylinder 804 for disinfection pretreatment. This invention features the following two parallel heart rate detection modes: Mode 1: Support-type transmission detection mode (for normal finger conditions). Medical staff guide the patient to naturally straighten the finger to be tested (such as the index finger) and place it on the horizontal plate 18. The rubber blocks 19 on the upper and lower ends of the horizontal plate 18 provide a non-slip and soft support surface for the finger, and perform initial positioning of the finger. Subsequently, medical staff started the detection program through controller 2. Controller 2 controlled the output shafts of the upper and lower electric cylinders 11 to slowly and synchronously extend. The electric cylinders 11 pushed the connecting block 16 through the second movable block 17, thereby driving the arc block 14 to rotate around the hinge point of the first movable block 13, so that the upper and lower test blocks 15 moved towards each other. During this process, the first heart rate sensor 20, the second heart rate sensor 21 and the third heart rate sensor 22 located in the recess of the test block 15 gradually approached and finally adhered to the skin on the upper and lower sides of the finger with a preset pressure. Controller 2 synchronously collected the photoplethysmography signals of the three sensors and compared and analyzed them, and automatically selected the signal output with the best signal-to-noise ratio as the final heart rate value. During this clamping process, the first movable block 13 on the outer wall of the arc block 14 pressed against the rubber cylinder 28 to form a flexible mechanical limit to prevent over-travel compression caused by electrical faults. Mode 2: Side-wall Reflective Detection Mode (for special patients with nail polish covering, excessively thick stratum corneum, or extremely weak peripheral circulation). When the transmissive detection signal is weak or the patient's fingers are inconvenient to lay flat, medical staff can switch to the side-attachment detection mode. The patient does not need to fully insert their fingers between the test blocks 15, but actively inserts the side of the finger (ulnar or radial side) and adheres it to the inner wall of the groove 23 opened on the side wall of the horizontal plate 18. The groove 23 is an arc-shaped depression that matches the physiological curvature of the side of the human finger. The patient's finger skin is directly and tightly pressed against the surface of the fourth heart rate sensor 24 fixed to the inner wall of the groove 23. The fourth heart rate sensor 24 adopts the principle of reflective photoelectric detection, emitting a specific wavelength light beam to the skin surface and receiving the reflected light signal. The controller 2 collects the data of the fourth heart rate sensor 24 and performs filtering and amplification processing to obtain an accurate heart rate value. This mode does not require clamping action, and the electric cylinder 11 remains in a reset and stationary state during the detection process. After the test is completed, the electric cylinder 11 resets and the finger is removed. Medical staff can periodically push the wiping frame 26 on the horizontal plate 18. The inner wall of the wiping frame 26 slides along the limiting strip 25, and the flexible material of its inner wall is used to scrape and clean the surface of the horizontal plate 18 and the window of the fourth heart rate sensor 24.
