Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a pulse detection device for cardiovascular clinical nursing. Background Technology

[0002] Currently, pulse detection is a routine and important monitoring method in the clinical nursing work of cardiovascular medicine. Traditional pulse detection methods mostly involve medical staff manually counting and sensing pulses by touching the patient's wrist, neck, and other areas where arterial pulsation is obvious.

[0003] However, many existing detection devices have limited functionality, typically only capable of detecting a specific area such as the fingers or wrist. They cannot flexibly collect pulse signals from multiple areas (such as the fingertips or the radial artery in the wrist) simultaneously or separately, depending on the patient's condition or testing needs. This limits their ease of use and comprehensiveness of detection. Secondly, when performing pulse detection, especially for the fingers, a challenge in existing designs is how to comfortably and effectively fix the patient's fingers to prevent displacement or poor contact of the detection head due to the patient's unconscious movements, which could affect the accuracy and stability of the test results. Some devices lack effective limiting structures, or the limiting structures are too rigid to accommodate fingers of different sizes, resulting in a poor patient experience and increasing the likelihood of detection errors. Utility Model Content

[0004] The purpose of this invention is to provide a pulse detection device for cardiovascular clinical nursing, which has the advantages of enabling pulse detection at multiple sites on the patient, improving detection comfort and accuracy, and enhancing detection sensitivity for patients with poor peripheral circulation through auxiliary pressurization function, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pulse detection device for cardiovascular clinical nursing includes a base plate, two first support blocks fixed to the upper part of the base plate, a fixed plate fixed to the upper part of the two first support blocks, a U-shaped cylinder fixed to the upper part of the fixed plate, a fixed cylinder through-and fixed to one end of the fixed plate, a first detection mechanism disposed in the fixed cylinder, an air pump disposed in one of the first support blocks, a second detection mechanism disposed on the upper part of the base plate, and a third detection head fixed to the concave surface of the U-shaped cylinder.

[0007] The inner wall of the U-shaped cylinder is equipped with a limiting mechanism for restricting finger movement.

[0008] Preferably, the first detection mechanism includes an inner cylinder fixed to the inner wall of the fixed cylinder, an air bladder slidably disposed on the inner wall of the inner cylinder, a third rubber cylinder slidably disposed on the inner wall of the air bladder, a first detection head fixed to the bottom surface of the inner wall of the third rubber cylinder, and an air inlet pipe fixed to one end of the air bladder, wherein the air outlet end of the air pump is connected to the air inlet end of the air inlet pipe through a pipe.

[0009] It is worth noting that when the air pump inflates or deflates the airbag through the air inlet tube, the airbag deforms and compresses the inner cylinder, allowing the position of the first detection head relative to the finger to be precisely and flexibly adjusted. This ensures that the detection head fits the patient's fingertip with appropriate pressure, improving detection accuracy. At the same time, the airbag, as a buffer medium, can effectively absorb the patient's involuntary slight tremors, providing a relatively stable detection environment for the first detection head. This significantly improves the accuracy and stability of pulse signal acquisition, making it particularly suitable for people with cardiovascular diseases who require precise monitoring.

[0010] Preferably, the second detection mechanism includes a second support block fixed to the upper end of the base plate, a bearing block fixed to the upper end of the second support block, two limiting blocks fixed to the upper end of the bearing block, a movable plate slidably disposed between the two limiting blocks, and a second detection head fixed to the upper end of the movable plate.

[0011] It is worth noting that the movable plate is slidably positioned between the two limiting blocks, allowing the second detection head, which is fixed to the upper end of the movable plate, to be adjusted in position along the track defined by the limiting blocks in the horizontal direction. This movable detection mechanism design brings great convenience and adaptability to clinical nursing operations, allowing users to place their fingertips on the second detection head for testing.

[0012] Preferably, multiple reinforcing blocks are fixed to both ends of the fixed plate, and the side wall of each reinforcing block is fixed to the outer peripheral wall of the U-shaped cylinder.

[0013] It is worth noting that the reinforcing block is simultaneously fixed to the end face of the fixed plate and the outer peripheral wall of the U-shaped cylinder, forming a stable triangular or trapezoidal support structure between the two. In actual clinical operation, when the patient puts their finger into the U-shaped cylinder, or when the nursing staff performs the test, the U-shaped cylinder will inevitably be subjected to accidental bumps or pressure from various directions. The presence of the reinforcing block can effectively disperse and transfer these external forces to the fixed base structure, effectively preventing the U-shaped cylinder from loosening relative to the fixed plate, thereby ensuring the structural stability and reliability of the entire testing device for long-term use and extending the service life of the device.

[0014] Preferably, the limiting mechanism is a silicone tube fixed to the inner wall of the U-shaped tube.

[0015] It is worth noting that the silicone tube, as a limiting mechanism, is directly fixed to the inner wall of the U-shaped tube, providing a soft, hygienic, and elastic space for the patient's finger. The silicone material itself has good biocompatibility and skin-friendly properties, which can effectively reduce the cold feeling and discomfort that patients may experience when in contact with hard materials, thus improving the comfort of the testing process. At the same time, the silicone tube has a certain degree of elastic deformation capability, which can adaptively wrap around fingers of different thicknesses to achieve flexible physical limiting, preventing the finger from shifting laterally or lifting up during the testing process, and ensuring that the fingertip can stably cover the testing area at the bottom of the U-shaped tube.

[0016] Preferably, the limiting mechanism includes a U-shaped first rubber cylinder fixed to the inner wall of the U-shaped cylinder and a first vertical plate fixed to the upper ends of the two ends of the first rubber cylinder.

[0017] It is worth noting that the limiting mechanism adopts a structure combining a first rubber cylinder and a first upright plate, which is a further optimization of the finger limiting function. The first rubber cylinder provides basic flexible wrapping and limiting functions, while the first upright plate at both ends plays a key auxiliary positioning function. When the patient inserts their finger into the U-shaped cylinder, the first upright plate can naturally fit against the upper side of the first and second joints of the finger, forming a clear blocking structure. This effectively prevents the finger from sliding back and forth during the test due to muscle relaxation or external contact, ensuring that the finger is always in the preset standard test position. This dual limiting design retains the comfort of the rubber material and enhances the positioning accuracy through rigid (or semi-rigid) upright plates, enabling the first detection mechanism to more stably and consistently align with the accurate part of the fingertip, improving the repeatability of the test and the reliability of the results.

[0018] Preferably, the limiting mechanism further includes a plurality of rubber columns fixed to one end of the two first upright plates that are close to each other, and the plurality of rubber columns are equidistantly distributed in the vertical direction.

[0019] It is worth noting that multiple equidistant rubber pillars are added at the ends of the first upright plate that are close to each other. These pillars can form multi-point contact with the side contours of the fingers. When a finger is inserted, fingers of different diameters will have different degrees of contact and compression with the rubber pillars of corresponding heights. The elastic deformation of the rubber pillars can adaptively fill the gap between the finger and the upright plate, achieving a close fit and flexible fixation for fingers of different thicknesses. This avoids the defect that a single flat upright plate may not be able to effectively fix thinner fingers. In addition, the equidistantly distributed rubber pillars can also provide a slight massage effect, promote local blood circulation, further reduce the numbness that may be caused by prolonged testing, and greatly improve the patient's comfort.

[0020] Preferably, the limiting mechanism includes a U-shaped second rubber cylinder fixed to the inner wall of the U-shaped cylinder, a second vertical plate fixed to the upper ends of the two ends of the second rubber cylinder, a groove formed at the lower part of one end of the two second vertical plates, a plurality of springs fixed to the inner wall of the groove, a movable block fixed to one end of the spring, and a rubber ball fixed to the movable block. The movable block is located inside the groove, and the upper and lower end faces of the movable block are in contact with the upper and lower end faces of the inner wall of the groove. The rubber ball is located outside the groove.

[0021] It is worth noting that this limiting mechanism adopts a spring-preloaded floating rubber ball structure, achieving flexible adaptive fixation and pressure buffering for the finger. When the finger is placed in the second rubber cylinder, the side of the finger will contact the protruding rubber ball. Under the action of the spring, the rubber ball slides within the groove guided by the movable block, always maintaining a gentle and appropriate force against the side of the finger. Because the movable block fits against the inner wall of the groove, the stability of the rubber ball's movement is ensured, allowing it to extend and retract only in a predetermined direction, thus accurately clamping the finger from both sides. This design not only adapts to fingers of different thicknesses, providing stable lateral positioning and preventing finger displacement, but also the point-like contact of the rubber ball and the elastic cooperation of the spring can buffer when the finger vibrates slightly, isolating interference outside the detection area. This ensures that the detection head located below the fingertip can collect a pure and stable pulse signal, demonstrating an organic combination of human-centered design and high-precision detection.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model effectively solves the problem of traditional detection devices having a single function and being unable to flexibly switch detection sites by setting up multiple detection mechanisms. Specifically, by integrating the first detection mechanism for finger detection into the fixed cylinder and independently setting the second detection mechanism for fingertip detection on the base plate, it is even possible to monitor multiple sites at the same time. This structural design makes the device highly clinically adaptable, not only meeting the individualized detection needs of patients with different conditions, but also significantly improving the convenience of nursing operations and the comprehensiveness of detection data.

[0024] 2. This device incorporates a limiting mechanism with elastic elements within the U-shaped cylinder. Taking one embodiment as an example, when a patient's finger is inserted into the limiting space formed by the second rubber cylinder and the second upright plate with spring-loaded pre-tightened rubber balls on both sides, the rubber balls, under the action of the springs, always maintain a flexible force against both sides of the finger. On one hand, the guiding cooperation between the movable block and the groove ensures the stability of the clamping force direction, achieving adaptive fixation for fingers of different thicknesses and effectively preventing displacement of the detection head caused by the patient's unconscious movements. On the other hand, the elastic cooperation between the rubber balls and the springs can absorb minor finger vibrations, providing a stable detection environment for the first detection head located below the fingertip. This improves the patient's wearing comfort while ensuring the accuracy and reliability of pulse signal acquisition.

[0025] 3. This device solves the problem of traditional detection heads being unable to flexibly adjust according to the shape of the fingertip through the coordinated design of the air bladder and inner cylinder in the first detection mechanism. When the air pump inflates the air bladder through the air inlet pipe, the air bladder expands evenly and pushes the third rubber cylinder and the first detection head closer to the fingertip, so that the detection head can fit against the detection site with appropriate and adjustable pressure. This flexible pressure mechanism not only avoids patient discomfort or local blood circulation obstruction due to excessive pressure, but also eliminates signal distortion caused by poor contact due to insufficient pressure. Especially for patients with poor peripheral circulation, moderate pressure can improve local blood perfusion, thereby significantly improving the detection sensitivity and waveform clarity of the pulse signal.

[0033] The technical solutions of the present utility model 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To address the shortcomings of existing technologies, such as limited functionality, inability to flexibly detect multiple body sites, poor finger fixation adaptability to fingers of varying sizes, and insufficient sensitivity for patients with weak pulses, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-6 ;

[0035] A pulse detection device for cardiovascular clinical nursing includes a base plate 1, two first support blocks 2 fixed to the upper end of the base plate 1, a fixed plate 3 fixed to the upper end of the two first support blocks 2, a U-shaped cylinder 4 fixed to the upper end of the fixed plate 3, a fixed cylinder 5 fixed through a section of the fixed plate 3, a first detection mechanism disposed in the fixed cylinder 5, an air pump 6 disposed in one of the first support blocks 2, a second detection mechanism 7 disposed on the upper end of the base plate 1, and a third detection head 8 fixed to the concave surface of the U-shaped cylinder 4.

[0036] The inner wall of the U-shaped cylinder 4 is provided with a limiting mechanism for limiting the finger position.

[0037] It should be noted that a controller (not shown) is provided on the upper end of the base plate 1. The third detection head 8 is fixed to the concave surface of the U-shaped cylinder 4 and can be used to detect the pulse on the side of the finger. Its signal output terminal is connected to the controller. In addition, all electrical devices are electrically connected to the controller.

[0038] In this embodiment, specifically: the first detection mechanism includes an inner cylinder 501 fixed to the inner wall of the fixed cylinder 5, an airbag 502 slidably disposed on the inner wall of the inner cylinder 501, a third rubber cylinder 503 slidably disposed on the inner wall of the airbag 502, a first detection head 504 fixed to the bottom surface of the inner wall of the third rubber cylinder 503, and an air inlet pipe 505 fixed to one end of the airbag 502. The air outlet end of the air pump 6 is connected to the air inlet end of the air inlet pipe 505 through a pipe.

[0039] In this embodiment, specifically: the second detection mechanism 7 includes a second support block 701 fixed to the upper end of the base plate 1, a bearing block 702 fixed to the upper end of the second support block 701, two limiting blocks 703 fixed to the upper end of the bearing block 702, a movable plate 704 slidably disposed between the two limiting blocks 703, and a second detection head 705 fixed to the upper end of the movable plate 704.

[0040] In this embodiment, specifically: multiple reinforcing blocks 301 are fixedly connected to both ends of the fixed disk 3, and the side wall of each reinforcing block 301 is fixedly connected to the outer peripheral wall of the U-shaped cylinder 4.

[0041] Example 1: In this example, the specific limiting mechanism is a silicone tube 401 fixed to the inner wall of the U-shaped tube 4. By using the silicone tube 401 as the limiting structure, the good biocompatibility and skin-friendly properties of silicone material itself significantly improve the comfort of the patient's fingers when in contact, avoiding the cold feeling and pressure discomfort caused by hard materials. At the same time, the silicone tube 401 has a certain elastic deformation capability, which can adaptively wrap around fingers of different thicknesses to achieve flexible physical limiting, effectively preventing the fingers from shifting laterally or lifting up during the detection process, ensuring that the fingertip can stably cover the detection area, and providing a basic guarantee for the accurate acquisition of pulse signals.

[0042] Example 2: In this example, the limiting mechanism specifically includes a U-shaped first rubber cylinder 402 fixed to the inner wall of the U-shaped cylinder 4 and a first upright plate 403 fixed to the upper ends of the two ends of the first rubber cylinder 402. This design, based on the flexible wrapping and limiting provided by the first rubber cylinder 402, adds the first upright plate 403 structure. When the patient's finger is inserted, the first upright plate 403 can conform to the upper side of the finger joint, forming a clear axial block, effectively preventing the finger from sliding back and forth due to muscle relaxation or external contact, ensuring that the finger is always in the preset standard detection position. This dual limiting design retains the comfort of the rubber material while enhancing the positioning accuracy through the upright plate, allowing the first detection mechanism to more stably align with the fingertip detection area, improving the repeatability of the detection and the reliability of the results.

[0043] In this embodiment, specifically, the limiting mechanism further includes multiple rubber pillars 404 fixed to one end of the two first upright plates 403 that are close to each other. The multiple rubber pillars 404 are equidistantly distributed in the vertical direction. By setting vertically distributed rubber pillars 404 on opposite sides of the two first upright plates 403, multi-point flexible contact with the side contour of the finger is achieved. When fingers of different thicknesses are inserted, the rubber pillars 404 can adaptively fill the gap between the finger and the upright plate through elastic deformation, achieving close fit and stable fixation for various types of fingers, avoiding the defect of insufficient fixation for thinner fingers by a single planar upright plate. At the same time, the multi-point distributed rubber pillars 404 can also play a slight massage role, promote local blood circulation, further reduce the discomfort that may be caused by long-term testing, and improve the patient experience.

[0044] Example 3: In this example, the limiting mechanism specifically includes a U-shaped second rubber cylinder 405 fixed to the inner wall of the U-shaped cylinder 4, a second vertical plate 406 fixed to the upper ends of the two ends of the second rubber cylinder 405, a groove 407 formed at the lower part of one end of the two second vertical plates 406, a plurality of springs 408 fixed to the inner wall of the groove 407, a movable block 409 fixed to one end of the spring 408, and a rubber ball 410 fixed to the movable block 409. The movable block 409 is located inside the groove 407, and the upper and lower end faces of the movable block 409 are in contact with the upper and lower end faces of the inner wall of the groove 407. The rubber ball 410 is located outside the groove 407. This embodiment achieves high-precision adaptive fixation of the finger. When the finger is inserted, the rubber ball 410 slides along the groove 407 guided by the movable block 409 under the elastic force of the spring 408, always keeping it close to the side of the finger with a gentle and appropriate force. The fit between the movable block 409 and the inner wall of the groove 407 ensures the stability of the movement and makes the direction of the clamping force precise and controllable.

[0045] Working principle: When performing pulse detection in cardiovascular clinical nursing, medical staff first select the appropriate detection mode according to the patient's specific detection needs. When it is necessary to collect pulse signals from the fingertip of the patient, the patient inserts the finger into the U-shaped tube 4 fixed to the upper end of the fixed plate 3. At this time, the limiting mechanism set on the inner wall of the U-shaped tube 4 starts to work, which flexibly wraps and laterally limits the finger, adaptively conforms to the contour of the finger of different thicknesses, effectively prevents the finger from unconsciously sliding back and forth or laterally displacing during the detection process, and ensures that the fingertip stably covers the detection area.

[0046] In Example 1, the limiting mechanism is a silicone tube 401 fixed to the inner wall of the U-shaped tube 4. When the patient's finger is inserted, the silicone tube 401 uses its own elastic deformation ability to adaptively wrap around the outer periphery of the finger, forming a flexible circumferential limiting for the entire finger. This avoids the pressure discomfort caused by hard materials and effectively prevents the finger from shifting laterally or lifting up during the detection process, ensuring that the fingertip stably covers the detection area.

[0047] In Embodiment 2, the limiting mechanism includes a first rubber cylinder 402 fixed to the inner wall of the U-shaped cylinder 4 and first upright plates 403 fixed to the upper ends of the two ends of the first rubber cylinder 402. When a patient's finger is inserted, the first rubber cylinder 402 provides basic flexible wrapping and radial limiting. At the same time, the two first upright plates 403 located above the finger joint side form an axial barrier, effectively preventing the finger from sliding back and forth due to muscle relaxation or external contact. On this basis, multiple rubber pillars 404 fixed to the two first upright plates 403 close to each other at one end form multi-point flexible contact with the side contour of the finger through equidistant distribution in the vertical direction. When fingers of different thicknesses are inserted, the rubber pillars 404 can adaptively fill the gap between the finger and the upright plates through elastic deformation, achieving close fit and stable fixation for various types of fingers, further enhancing the reliability and comfort of the limiting mechanism.

[0048] In embodiment 3, the limiting mechanism includes a second rubber cylinder 405 fixed to the inner wall of the U-shaped cylinder 4, second vertical plates 406 fixed to the upper ends of the two ends of the second rubber cylinder 405, grooves 407 formed at the lower part of the two second vertical plates 406 near each other, multiple springs 408 fixed to the inner wall of the grooves 407, a movable block 409 fixed to one end of the springs 408, and a rubber ball 410 fixed to the movable block 409. When the patient's finger is inserted into the second rubber cylinder 405, the side of the finger contacts the rubber ball 410 protruding from the outside of the grooves 407; under the elastic force of the springs 408, the rubber ball 410 slides along the inner wall of the grooves 407 guided by the movable block 409, always keeping a gentle and appropriate force against the side of the finger. Since the upper and lower end faces of the movable block 409 are in contact with the upper and lower end faces of the inner wall of the grooves 407, the stability of the movement of the rubber ball 410 is ensured, so that it can only extend and retract in a predetermined direction, thereby accurately clamping the finger from both sides;

[0049] After the finger is stably fixed by the limiting mechanism, the air pump 6 set in the first support block 2 is started by the controller (not shown). The controller precisely controls the working state of the air pump 6 according to the preset program or the operation instructions of the medical staff. The air pump 6 is connected to the air inlet end of the air inlet pipe 505 through the pipe to control the inflation of the air bag 502 in the first detection mechanism in the fixed cylinder 5. After the air bag 502 is inflated, it deforms and pushes the third rubber cylinder 503 slidably set on its inner wall and the first detection head 504 fixed to the bottom surface of the inner wall of the third rubber cylinder 503, so that it gradually approaches the fingertip along the inner wall of the inner cylinder 501 and fits with appropriate and adjustable pressure. After fitting, the first detection head 504 can start to stably collect the pulse signal of the fingertip and transmit the collected data to the controller for processing and display in real time.

[0050] When it is necessary to detect the pulse at the fingertip of a patient, the patient can place their finger on the support block 702 in the second detection mechanism 7, aligning the fingertip with the second detection head 705 fixed to the upper end of the movable plate 704. By pushing the movable plate 704 which is slidably disposed between the two limit blocks 703, the second detection head 705 is adjusted in position in the horizontal direction along the track defined by the limit blocks 703, precisely adapting to fingers of different lengths, ensuring good contact between the fingertip and the second detection head 705. Subsequently, the second detection head 705 begins to collect the pulse signal of the fingertip and transmits the data to the controller in real time.

[0051] Furthermore, the third detection head 8, fixed to the concave surface of the U-shaped cylinder 4, can serve as an auxiliary detection unit, providing supplementary monitoring of other parts of the patient's fingers while detecting the finger, or it can be used independently under specific nursing needs. Its detection data is also aggregated to the controller for comprehensive analysis. During operation, multiple reinforcing blocks 301 fixed to both ends of the fixed plate 3 are interconnected with the outer peripheral wall of the U-shaped cylinder 4, forming a stable support structure that effectively disperses external impacts, ensuring the positional accuracy and structural stability of the U-shaped cylinder 4, its internal limiting mechanism, and the first detection mechanism during long-term use. Through the unified coordination of the controller and the collaborative work of each detection mechanism, flexible, comfortable, and accurate pulse detection of multiple parts of the patient's fingers is achieved.
