Description

Technical Field

[0001] This utility model relates to the field of zeroing technology for pressure sensors, specifically a novel zeroing and fixing device for medical pressure sensors. Background Technology

[0002] In clinical practice, invasive hemodynamic monitoring is a crucial tool for assessing patients' circulatory function and guiding treatment decisions in scenarios such as intensive care and surgical procedures. This monitoring method requires inserting a catheter through the patient's skin into the heart chambers or blood vessels. Using a monitor and pressure sensors, key physiological parameters such as direct arterial pressure, central venous pressure, pulmonary artery pressure, and cardiac output are directly measured. The accuracy of these parameters directly determines the precision of medical personnel's assessment of the patient's condition, thus affecting the formulation and implementation of treatment plans.

[0003] However, current methods for fixing and zeroing pressure sensors used in clinical practice have significant drawbacks: existing fixing tools are mostly simple brackets or adhesive tape. Brackets cannot flexibly adapt to different models of pressure sensors, and their height adjustment accuracy is low, making it difficult to accurately locate the zero point. Adhesive tape is easily affected by factors such as sweat and impacts during operation, causing the sensor to shift. Furthermore, frequent tape replacements increase the consumption of medical consumables and operation time. In the zeroing process, medical staff often rely on visual observation and experience, lacking standardized positioning tools. This makes it difficult to ensure precise alignment of the zero point with the midpoint of the right atrium. Especially in scenarios with frequent surgical procedures or when patient positioning needs to be temporarily adjusted, the zeroing error further increases, seriously affecting the reliability of monitoring data. This could lead to misjudgments of the patient's condition, delays in treatment, or an increased risk of overtreatment.

[0004] Therefore, developing a fixation device that enables convenient fixation and precise zeroing of pressure sensors, while also being highly adaptable and easy to operate, has become a key requirement for addressing current clinical pain points and improving the quality of invasive hemodynamic monitoring. Utility Model Content

[0005] The purpose of this invention is to provide a novel zeroing and fixing device for a medical pressure sensor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel medical pressure sensor zeroing and fixing device, comprising a movable panel, a connecting device, a fixing device, and a zeroing device, wherein the connecting device is connected to the movable panel and an external upright, the fixing device is disposed on the front of the movable panel, and the zeroing device is disposed on the back of the movable panel.

[0007] Preferably, the movable panel is equipped with a horizontal adjustment component, which is linked to the zeroing device. The horizontal adjustment component can be used to adjust the horizontal state of the movable panel to ensure that the movable panel is flush with the operating room floor. This avoids deviation in zeroing of the pressure sensor due to tilting of the movable panel, provides a stable and horizontal installation reference for the pressure sensor, and ensures zeroing accuracy.

[0008] Preferably, the horizontal adjustment component includes a ball head fixed to one side of the movable panel and a ball sleeve fixed to one side of the connecting device. The surface of the ball sleeve is provided with a locking bolt, wherein the threaded end of the locking bolt abuts against the surface of the ball head. This enables flexible angle adjustment of the movable panel in multiple directions. After adjustment, the ball head can be tightened by the locking bolt to quickly fix the position of the movable panel. This balances the flexibility of adjustment with the stability of fixation. The operation is convenient and the structure is stable after adjustment, making it less prone to loosening.

[0009] Preferably, the connecting device adopts a sliding connecting structure. One end of the connecting device is connected to the movable panel, and the other end is sleeved on the external upright. The connecting device is equipped with a locking component. The height of the movable panel can be adjusted up and down along the upright by sliding the connecting device. After adjustment, the relative position of the connecting device and the upright is fixed by the locking component. This facilitates adaptation to the installation height requirements of pressure sensors in different operating room scenarios. After adjustment, the locking component can stably maintain the adjusted height position, preventing the movable panel from accidentally sliding during use and improving the adaptability and safety of the device.

[0010] Preferably, the fixing device includes two pressure sensor bayonets, which are symmetrically arranged on the front of the movable panel. Each pressure sensor bayonet has an adjusting screw at one end. The inner diameter of the bayonet can be changed by rotating the adjusting screw to accommodate pressure sensors of different sizes. This allows for detachable fixing of the pressure sensors. By changing the inner diameter of the bayonet by rotating the screw, different sizes of pressure sensors can be accommodated without the need for separate fixing devices for different sensors, thus reducing operating costs. At the same time, the detachable fixing of the pressure sensors facilitates the installation, removal, and maintenance of the sensors, improving operational convenience.

[0011] Preferably, the zeroing device includes a leveling instrument and an infrared emitter, which can monitor the levelness of the movable panel in real time. The infrared emitter is fixed to the back of the movable panel, and the emission direction of the infrared emitter is perpendicular to the mounting plane of the pressure sensor. The zero point position of the pressure sensor can be located by the infrared light emitted by the infrared emitter, which can accurately locate the zero point position of the sensor, reduce the error of manual positioning, make the zeroing operation more intuitive and accurate, improve the zeroing efficiency and accuracy, and ensure the reliability of the pressure sensor measurement data.

[0012] Preferably, the movable panel is made of ABS engineering plastic, and the edges of the movable panel have rounded corners. A silicone anti-slip pad is attached to the inner wall of the pressure sensor slot of the fixing device. The surface of the silicone anti-slip pad has anti-slip texture, which can prevent the pressure sensor from sliding or wearing during the fixing process. The silicone anti-slip pad and the surface anti-slip texture on the inner wall of the fixing device slot can increase the friction with the pressure sensor, prevent the sensor from sliding after fixing. At the same time, the silicone material can buffer collisions, avoid wear on the sensor surface, protect the integrity of the sensor, and extend its service life.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This new medical pressure sensor zeroing and fixing device can be flexibly adjusted in terms of installation height and level to adapt to the needs of different operating room scenarios. At the same time, it can be adapted to various models of pressure sensors through adjustable structure, eliminating the need to equip different devices with separate fixing devices and reducing the cost of use.

[0014] This new medical pressure sensor zeroing and fixing device relies on real-time level monitoring and precise positioning guidance during the zeroing process, which greatly reduces human operation errors, ensures the reliability of pressure sensor measurement data, provides accurate data support for monitoring patients' vital signs during surgery, and reduces medical risks caused by equipment problems.

[0017] 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.

[0018] Please see Figure 1-4The present invention provides the following technical solution: a novel medical pressure sensor zeroing and fixing device, comprising four major components: a movable panel 1, a connecting device 2, a fixing device 3, and a zeroing device 4. The components work together to achieve precise fixing and efficient zeroing of the pressure sensor, adapting to the strict requirements of medical scenarios such as operating rooms.

[0019] The connecting device 2 serves as the connection component between the device and the external support structure. One end is stably connected to the movable panel 1 through an adapter structure, ensuring that there is no loose gap after the connection. The other end adopts a sleeve-type design with an inner diameter that matches the external upright, allowing it to be tightly fitted onto the external upright, thus assembling the entire device with the upright. The fixing device 3 is integrated on the front of the movable panel 1, directly contacting the pressure sensor and undertaking the responsibility of fixing the sensor, ensuring the stability of the sensor's position during use. The zeroing device 4 is installed on the back of the movable panel 1, avoiding the sensor fixing area on the front. This does not affect the sensor installation and allows for close monitoring of the status of the movable panel 1, providing data support and positioning guidance for the zeroing operation.

[0020] The movable panel 1 is made of ABS engineering plastic in one piece. This material not only has excellent impact resistance and can withstand minor collisions during daily operations in the operating room, but also has a smooth surface that is easy to clean and can be wiped and disinfected with medical disinfectant, meeting medical hygiene standards. The edges of the movable panel 1 are finely polished to form a rounded corner structure, which effectively avoids the risk of sharp edges causing scratches to medical staff and improves the safety of use. The horizontal adjustment component 11 is a key component for adjusting the horizontal state of the active panel 1. It forms a linkage mechanism with the zeroing device 4. The zeroing device 4 provides real-time feedback on the horizontal data of the active panel 1, and medical staff make precise adjustments through the horizontal adjustment component 11 based on the data. The component specifically includes a metal ball head fixed to one edge of the movable panel 1. The ball head is made of stainless steel and its surface is polished to ensure smooth rotation. Correspondingly, a metal ball sleeve adapted to the ball head is fixed to the side of the connecting device 2 near the movable panel 1. The inner wall of the ball sleeve fits tightly with the ball head, ensuring that the ball head can rotate flexibly within the ball sleeve while preventing excessive shaking. A threaded hole is opened on the side of the ball sleeve. After the locking bolt passes through the threaded hole, its threaded end can directly abut against the surface of the ball head. When the movable panel 1 is adjusted to a horizontal position, the locking bolt is tightened clockwise. The pressure between the bolt and the ball head fixes the position of the ball head, thereby locking the horizontal position of the movable panel 1. No parts need to be disassembled during the adjustment process. The operation can be completed by a single person, taking into account both flexibility and stability. The structure is stable after adjustment, and even in the environment of frequent instrument movement in the operating room, it is not easy to loosen and cause the movable panel 1 to tilt.

[0021] The connecting device 2 adopts a sliding connection structure. The inner wall of the sleeve that mates with the external upright has anti-slip textures, which increases the friction with the surface of the upright and prevents accidental slippage during adjustment. The side of the connecting device 2 has a locking component for fixing. This locking component is a knob-type design, with a rubber pressure block connected to the inside of the knob. When it is necessary to adjust the height of the movable panel 1, the knob is rotated counterclockwise, and the rubber pressure block separates from the surface of the upright. At this time, the connecting device 2 can be pushed up and down along the upright. During the sliding process, the height of the movable panel 1 can be flexibly adjusted according to the actual needs of the operating room to meet the usage requirements of most operating room scenarios. When the height is adjusted to the correct position, the knob is rotated clockwise, and the rubber pressure block is tightly pressed against the surface of the upright under the pressure of the knob. The relative position of the connecting device 2 and the upright is fixed by friction. After fixing, the connecting device 2 has no vertical displacement, ensuring the height of the movable panel 1 is stable. This prevents the device from slipping during use and affecting the normal operation of the pressure sensor, further improving the adaptability and safety of the device.

[0022] The fixing device 3 includes two pressure sensor bayonets symmetrically arranged on the front of the movable panel 1. The spacing between the bayonets is designed according to the size of common pressure sensors to ensure that both bayonets can stably clamp the sensor simultaneously. Each pressure sensor bayonet adopts a semi-open structure, with the opening facing the edge of the movable panel 1 for easy insertion and removal of the sensor. One end of the bayonet is equipped with an adjusting screw made of plastic to avoid wear caused by contact with the metal sensor. One end of the screw extends into the bayonet and is connected to an arc-shaped clamping block. The inner wall of the clamping block is lined with a silicone pad. The other end is equipped with a knob for easy rotation. When installing the pressure sensor, the sensor... Insert the device between the two bayonets and rotate the adjusting screw knob clockwise. The arc-shaped clamping block moves towards the sensor under the push of the screw until it makes tight contact with the sensor surface. The sensor is then fixed in place by the clamping force of the two bayonets. If different sensor models are used, simply rotate the adjusting screw to change the inner diameter of the bayonets to accommodate different pressure sensor models. This eliminates the need for separate fixing devices for different sensors, reducing the procurement and maintenance costs of medical equipment. At the same time, the detachable fixing method allows for quick installation and removal of the sensor, facilitating routine maintenance, calibration, or replacement by medical personnel and significantly improving operational convenience.

[0023] The zeroing device 4 consists of a level adjuster 41 and an infrared emitter 42. Both are connected to a miniature power supply module inside the movable panel 1 via wires. The power supply module is rechargeable. The level adjuster 41 features a digital display screen located prominently on the reverse side of the movable panel 1, displaying real-time level data. Medical personnel can intuitively understand the level status of the movable panel 1 through the display screen for timely adjustments. The infrared emitter 42 is fixed at the center of the reverse side of the movable panel 1, with its emission direction strictly perpendicular to the mounting plane of the pressure sensor. The emitted infrared... The infrared light is visible red with a wavelength between 620-660nm, providing moderate brightness that is easy for medical staff to observe without interfering with surgical procedures. The infrared emitter 42 has its infrared emission port flush with the three-way valve of the pressure sensor. When zeroing the pressure sensor, the infrared light is simply projected horizontally onto the center of the patient's right atrium, at the intersection of the mid-axillary line and the fourth intercostal space, to complete the zero-point positioning. This makes the zeroing operation more intuitive and precise, improving zeroing efficiency and accuracy, and ensuring the reliability of the pressure sensor's measurement data, thus providing accurate data support for monitoring vital signs during surgery.

[0024] The silicone anti-slip pad attached to the inner wall of the pressure sensor bayonet of the fixing device 3 is made of medical-grade silicone, which has good elasticity and wear resistance and meets medical non-toxic standards. The anti-slip texture on the surface of the silicone pad is a cross-grid pattern, which can further increase the friction with the surface of the pressure sensor. Even if the sensor surface is smooth, it can effectively prevent it from sliding during the fixing process. At the same time, the elasticity of the silicone material can buffer the pressure between the bayonet and the sensor, avoiding scratches or squeezing damage to the sensor surface caused by metal or hard plastic bayonet, protecting the appearance and internal structure of the sensor, extending the service life of the sensor, and reducing the replacement frequency and cost of medical equipment.

[0025] In use, first assemble the entire device with the external upright using the connecting device 2. After sliding the connecting device 2 along the upright to a suitable height, rotate the knob-type locking piece on its side to make the rubber pressure block tightly fit the surface of the upright and fix its position. Then, according to the real-time level data displayed by the level adjuster 41 in the zeroing device 4, the medical staff adjust the level adjustment component 11 on the movable panel 1. By rotating the locking bolt on the ball sleeve surface on one side of the connecting device 2, the metal ball head on one side of the movable panel 1 can rotate flexibly inside the ball sleeve until the movable panel 1 is level with the operating room floor. Then tighten the locking bolt to fix the movable panel 1 in a level state. Then, the pressure is transmitted... The sensor is placed between the two symmetrical bayonets of the front fixing device 3 of the movable panel 1. The adjusting screw at one end of the bayonet is rotated clockwise to push the arc-shaped clamping block towards the sensor and clamp it tightly. The anti-slip texture of the silicone anti-slip pad on the inner wall of the bayonet prevents the sensor from sliding. When zeroing, the height of the pressure sensor is adjusted so that the three-way valve of the pressure sensor is level with the infrared emission port. The infrared emitter 42 of the zeroing device 4 is opened, and the emitted visible red light is horizontally projected onto the center of the patient's right atrium, that is, the intersection of the mid-axillary line and the fourth intercostal space. The zeroing operation is then completed. Throughout the process, all components work together to achieve stable fixation and accurate zeroing of the pressure sensor.
