Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a non-invasive arterial blood pressure and blood flow monitoring device that can be quickly positioned and installed. Background Technology

[0002] In the field of modern medical diagnosis and monitoring, non-invasive arterial blood pressure and blood flow monitoring devices are widely used in clinical diagnosis and treatment, home health monitoring, and other scenarios as key equipment for assessing patients' cardiovascular health. These devices acquire key physiological parameters such as arterial blood pressure and blood flow in real time through non-invasive measurement methods, providing important information for disease diagnosis, treatment planning, and disease monitoring. With the development of medical technology and the improvement of people's health awareness, higher demands are being placed on the accuracy, convenience, and patient comfort of non-invasive arterial blood pressure and blood flow monitoring devices. Current non-invasive arterial blood pressure and blood flow monitoring devices typically employ a traditional strap fixation method. Their mechanical structure generally uses ordinary buckles or Velcro to adjust the tightness of the strap, utilizing pressure sensors to detect arterial pulsation signals. During blood pressure and blood flow monitoring, medical staff must manually and repeatedly adjust the tightness of the strap to ensure a close fit to the patient's arm. The pressure sensor collects the pressure changes generated by arterial pulsation, which are then converted into physiological data such as blood pressure and blood flow. However, the manual adjustment required for existing monitoring devices is not only time-consuming and labor-intensive, increasing the workload of medical staff, but also makes it difficult to accurately adapt to the different arm sizes and shapes of patients. If too loose, the strap is prone to slipping or falling off, leading to inaccurate measurements; if too tight, it can cause patient discomfort, even affecting blood circulation, reducing patient cooperation and the monitoring experience. Therefore, how to achieve rapid installation and removal of the strap, and how to make it adaptable to different patient body shapes, has become a pressing technical challenge. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a non-invasive arterial blood pressure and blood flow monitoring device that can be quickly positioned and installed. It aims to improve the existing monitoring devices, which require manual adjustment of tightness, which is not only time-consuming and laborious, increasing the workload of medical staff, but also difficult to accurately adapt to the thickness and shape of different patients' arms.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a non-invasive arterial blood pressure and blood flow monitoring device that can be quickly positioned and installed, comprising a fixed support plate, with a restraint strap and a toothed sliding strap fixedly connected to the outer walls of both ends of the fixed support plate, a fixed block fixedly connected to one side of the outer wall of the restraint strap, a telescopic rod fixedly connected inside the fixed block, a spring sleeved on the outer wall of the telescopic rod, a barb fixedly connected to the other end of the spring, a baffle fixedly connected to the upper surface of the barb, both the barb and the baffle being slidably connected inside the fixed block, a rotating rod rotatably connected inside the fixed block, an elliptical turntable fixedly connected to the outer wall of the rotating rod, a limit block fixedly connected to the outer wall of the elliptical turntable, and a sliding rod slidably connected to the outer wall of the elliptical turntable.

[0005] Furthermore, an adhesive tape is attached to the middle of the outer wall of the fixed support plate, and one end of the adhesive tape is attached to the support frame.

[0006] Furthermore, a support frame is slidably connected to the middle of the outer wall of the fixed support plate, and a monitor body is fixedly connected to one end of the support frame. A disassembly and assembly assembly is provided inside the fixed support plate.

[0007] Furthermore, the disassembly and assembly assembly includes a slot and a block. The slot is formed at one end of the support frame. The block is slidably connected to the interior of a pre-set groove inside the fixed support plate. A limit plate is fixedly connected to the outer wall of the block. A telescopic slide rod is fixedly connected to one side of the outer wall of the block. A telescopic spring is sleeved on the outer wall of the telescopic slide rod. One side of the outer wall of the block is set as an inclined surface.

[0008] Furthermore, the outer wall of the limiting plate is slidably connected to the interior of a pre-set groove inside the fixed support plate.

[0009] Furthermore, one end of the telescopic spring is fixedly connected to the inside of the fixed support plate, and the other end of the telescopic spring is fixedly connected to the outer wall of the card block.

[0010] Furthermore, one end of the spring is fixedly connected to the inside of the fixed block, and the outer wall of the toothed sliding band is slidably connected to the inside of the fixed block.

[0011] Furthermore, the outer wall of the slide rod is slidably connected to the inside of the fixed block, and the outer wall of the limiting block is slidably connected to the inside of the fixed block.

[0012] This utility model has the following beneficial effects: 1. In this utility model, through the ingenious cooperation of the toothed sliding belt, the barb inside the fixing block, and the spring, the restraint belt can be quickly and tightly wrapped comfortably around the patient's arm. When the appropriate size is reached, it can be automatically fixed to prevent loosening and slippage. When disassembling, the restraint can be easily released by rotating the rotating rod to move the relevant parts. This not only realizes the quick installation and removal of the restraint belt, greatly saving the operation time of medical staff, but also allows for flexible adjustment of the restraint belt size to ensure that it can perfectly adapt to the arms of patients with different body types, significantly improving the convenience of the device and the comfort of the patient.

[0013] 2. In this utility model, after placing the fixed support plate under the patient's arm, the fixed bracket protruding from the radius bone is first installed so that the fingers can palpate the pulse to find the strongest point of the radial artery pulsation and draw a line. Then, the support frame is installed so that the arterial pulsation trend line is fixed between the red lines of the locator and aligned with the first wrist crease. Subsequently, the monitor body is successfully installed. This not only ensures the accurate positioning of the measurement position and improves the accuracy of blood pressure and blood flow monitoring data, but also makes the operation steps clear and easy to understand, greatly reducing the difficulty of operation for medical staff. It helps to quickly and efficiently complete the non-invasive arterial blood pressure and blood flow monitoring of patients in clinical practice. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1 - Figure 6 This utility model provides an embodiment of a non-invasive arterial blood pressure and blood flow monitoring device that can be quickly positioned and installed. It includes a fixed support plate 1. Two binding straps 13 and toothed sliding straps 14 are fixedly connected to the outer walls of both ends of the fixed support plate 1. A fixing block 15 is fixedly connected to one side of the outer wall of the binding straps 13. A telescopic rod 16 is fixedly connected inside the fixing block 15. A spring 17 is sleeved on the outer wall of the telescopic rod 16. A barb 18 is fixedly connected to the other end of the spring 17. A baffle 19 is fixedly connected to the upper surface of the barb 18. The barb 18 and the baffle 19... All 9 are slidably connected inside the fixed block 15. A rotating rod 21 is rotatably connected inside the fixed block 15. An elliptical turntable 22 is fixedly connected to the outer wall of the rotating rod 21. A limit block 23 is fixedly connected to the outer wall of the elliptical turntable 22. A sliding rod 20 is slidably connected to the outer wall of the elliptical turntable 22. One end of the spring 17 is fixedly connected to the inside of the fixed block 15. The outer wall of the toothed sliding belt 14 is slidably connected to the inside of the fixed block 15. The outer wall of the sliding rod 20 is slidably connected to the inside of the fixed block 15. The outer wall of the limit block 23 is slidably connected to the inside of the fixed block 15.

[0018] Specifically, the first step is to install the restraint strap 13: insert the toothed sliding strap 14 into the fixing block 15. The teeth on both sides slide smoothly along the smooth surface of the barbs 18. Under the push of the spring 17, the barbs 18 move flexibly on the outer wall of the teeth, allowing the restraint strap 13 to tightly and comfortably wrap around the patient's arm. When the restraint strap 13 shrinks to the ideal size, the spring 17 pushes the barbs 18 between the teeth, and the grooved surface of the barbs 18 fits tightly against the toothed sliding strap 14, thus fixing the restraint strap 13 and preventing it from loosening or slipping. For disassembly, rotate the rotating rod 21, causing the elliptical turntable 22 and the limiting block 23 to move smoothly within the fixing block 15. While the elliptical turntable 22 rotates, the sliding rod 20 slides within the fixing block 15 and applies pressure to the baffle 19, pushing the barbs 18 to move and release the restraint on the toothed sliding strap 14. This allows for quick installation and removal of the restraint strap 13 and can accommodate different patients.

[0019] Reference Figure 1 - Figure 6 A tape 2 is attached to the middle of the outer wall of the fixed support plate 1. One end of the tape 2 is attached to the support frame 3. A support frame 4 is slidably connected to the middle of the outer wall of the fixed support plate 1. One end of the support frame 4 is fixedly connected to the monitor body 5. The fixed support plate 1 is equipped with a disassembly assembly, which includes a slot 6 and a block 7. The slot 6 is opened at one end of the support frame 4. The block 7 is slidably connected to the inside of a pre-set slide groove 8 inside the fixed support plate 1. A limit plate 9 is fixedly connected to the outer wall of the block 7. A telescopic slide rod 10 is fixedly connected to one side of the outer wall of the block 7. A telescopic spring 11 is sleeved on the outer wall of the telescopic slide rod 10. One side of the outer wall of the block 7 is set as an inclined surface 12. The outer wall of the limit plate 9 is slidably connected to the inside of the pre-set slide groove 8 inside the fixed support plate 1. One end of the telescopic spring 11 is fixedly connected to the inside of the fixed support plate 1, and the other end of the telescopic spring 11 is fixedly connected to the outer wall of the block 7.

[0020] Specifically, first, place the fixed support plate 1 under the patient's arm, install the fixed bracket to protrude the radius, locate the strongest radial artery pulsation point by palpating the pulse with your fingers, and draw the arterial pulsation trend line; then install the support frame 3, fix the drawn line between the two red lines of the locator and align it with the first wrist crease, then push the locking block 7 into the fixed support plate 1, while the telescopic spring 11 retracts; next, align the monitor body 5 with the support frame 3 and fasten it, at which point the support frame 4 under the monitor body 5 slides on both sides of the outer wall of the fixed support plate 1, and finally, the return of the telescopic spring 11 pushes the locking block 7 back into the support frame 4 for fixation, completing the device installation.

[0021] Working principle: When using the non-invasive arterial blood pressure and blood flow monitoring device, firstly, when installing the restraint band 13 onto the patient's arm, simply insert the toothed sliding band 14 into the fixing block 15. The teeth on both sides of the toothed sliding band 14 will slide smoothly along the smooth surface of the barbs 18. Due to the pushing action of the spring 17, the barbs 18 can move flexibly on the outer wall of the teeth, ensuring that the restraint band 13 can be tightly and comfortably wrapped around the patient's arm. As the restraint band 13 gradually contracts, when it reaches the ideal size, the spring 17 will push the barbs 18 between the teeth. At this time, the grooved surface of the barbs 18 will... The toothed sliding band 14 fits tightly to effectively fix the restraint band 13, preventing it from loosening or slipping. When the restraint band 13 needs to be removed, simply rotate the rotating rod 21, which will drive the elliptical turntable 22 and the limiting block 23 to move smoothly inside the fixing block 15. As the elliptical turntable 22 rotates, the sliding rod 20 will also slide accordingly inside the fixing block 15, thereby applying pressure to the baffle 19 and further pushing the barb 18 to move, so that the toothed sliding band 14 is no longer restrained. This not only achieves quick installation and removal of the restraint band 13, but also ensures that the restraint band 13 can adapt to different patients. In addition, when using it, first place the fixed support plate 1 under the patient's arm, install the fixed bracket, protrude the radius, use your fingers to feel the pulse, find the point where the radial artery pulsation is strongest, draw a line of arterial pulsation trend, install the support frame 3, fix the drawn line between the two red lines on the locator, align it with the first wrist crease, then push the locking block 7 into the inside of the fixed support plate 1, at the same time the telescopic spring 11 retracts, then install the monitor body 5, align the monitor body 5 with the support frame 3, and snap it on directly. At this time, the support frame 4 under the monitor body 5 will slide on both sides of the outer wall of the fixed support plate 1, and then the rebound of the telescopic spring 11 pushes the locking block 7 back into the inside of the support frame 4 to fix it and complete the installation.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
