Description

Technical Field

[0001] The utility model belongs to the technical field of medical care and relates to a movable sensor fixing device. Background Art

[0002] In the modern intensive care medical field, patients with unstable hemodynamics or who need to undergo refined circulatory function monitoring, such as patients after cardiac surgery, often need to be implanted with precision monitoring devices such as the Pulse Indicator Continuous Cardiac Output (PICCO) system or floating catheter. These devices are equipped with a series of pressure sensors, which are used to measure the patient's arterial blood pressure (ABP), central venous pressure (CVP), pulmonary artery pressure (PAP) and other key vital sign parameters in real time.

[0003] However, the current sensor fixing method has obvious shortcomings. The traditional method is to attach each sensor and its connecting wires one by one to the periphery of the bed with simple medical tape. This method not only easily leads to disordered wire arrangement and visual untidiness, but also due to the lack of standard fixed position and structural design, it is difficult to ensure that the sensor is always accurately aligned with the fourth intercostal space of the patient's mid-axillary line, which directly affects the accuracy of monitoring data and the effectiveness of clinical decision-making.

[0004] In addition, due to the differences in individual heights of patients and their possible changes in their own positions in bed, existing solutions, such as using straps to tie sensors to bed rails or temporary brackets, often cannot adapt to different clinical scenarios and cannot achieve flexible, accurate and stable sensor positioning, thus failing to effectively solve the problem of easy displacement of sensor positions and complex wire management. Therefore, it is urgent to develop a special device for intensive care units that can standardize the fixed positions of multiple sensors, simplify bedside cable management, and adapt to changes in different heights and positions, so as to improve the quality of care and monitoring accuracy.

[0005] Patent CN212748124U discloses a temperature sensor processing detection device that is easy to position, including a device body and a limit rod, a clamping seat fixedly connected to the device body, and a lower clamping block fixedly connected to the upper side of the clamping seat, and a sensor body is placed on the lower clamping block, and a guide seat is installed on the upper left side of the clamping seat, a clamping plate is installed on the upper side of the clamping seat, and the bottom of the clamping plate is fixedly connected to the fixed column, and the bottom of the fixed column is fixedly connected to the guide tube, and the bottom of the clamping plate is fixedly connected to the upper clamping block, and a mounting plate is installed on the right side of the clamping seat, and the lower end of the mounting plate is fixedly connected to the limit block, and a constant temperature electric heating plate is installed on the upper side of the mounting plate. However, this patent can only be simply attached to the periphery of the bed, and cannot keep the device vertical in some non-horizontal parts, and cannot adapt to different clinical situations.

[0006] Patent CN215229788U discloses a multi-angle adjustable arm suspension device for surgery, including a support vertical plate, a long strip through hole is provided on the side of the support vertical plate, a connecting screw is rotated in the long strip through hole, a cross bar is arranged in the long strip through hole, a first through hole is provided on the bottom of the cross bar, a guide device is arranged between the cross bar and the long strip through hole, a plurality of arm straps are connected to the bottom of the cross bar, and a flexible belt is connected to the movable end of the arm strap, and the flexible belt can be used to suspend the arm, a clamping device is arranged at the bottom of the support vertical plate, and an adjustment device is arranged between the support vertical plate and the clamping device. Although the patent discloses bolts and U-shaped plates, the U-shaped plates are connected to the support vertical plates through vertical blocks, and the angle change of the support vertical plates is limited to the horizontal plane, and the number of blind holes for the pin to be inserted is limited, so the support vertical plates can only be stopped at specific positions in the horizontal plane. Utility Model Content

[0007] The purpose of the present utility model is to provide a movable sensor fixing device in order to overcome at least one defect of the above-mentioned prior art. The present utility model can be firmly clamped on any rod-shaped structure of the hospital bed, and the device can be adjusted to a vertical state according to the actual inclination angle of the bed armrest, thereby effectively preventing the device from rotating accidentally and realizing accurate positioning of patients of different body shapes.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0009] One of the technical solutions of the utility model is to provide a movable sensor fixing device, which includes a fixing seat, in which a clamping seat is slidably installed, and the fixing seat and the clamping seat clamp the installation position of the bed;

[0010] A fixed shaft is installed on one side of the fixed seat, and a rotating guide plate is rotatably installed on the fixed shaft;

[0011] A stop rod is slidably inserted on one side of the rotating guide plate near the fixed shaft, and a tension spring is sleeved on the stop rod. The tension spring pulls the stop rod to be squeezed with the fixed shaft to prevent the rotating guide plate from continuing to rotate;

[0012] The rotating guide plate is slidably sleeved with a sliding seat;

[0013] A plurality of sensor clamping blocks for clamping sensors are mounted on the sliding seat.

[0014] Furthermore, a clamping screw is inserted into one end of the fixing seat, and the end of the clamping screw is rotatably connected to the clamping seat.

[0015] Furthermore, the fixing seat and the clamping seat are both provided with arc-shaped grooves on their contact surfaces, and the arc-shaped grooves clamp the rod-shaped structure of the installation position of the hospital bed.

[0016] Furthermore, a fixing plate is provided on one side of the rotating guide plate near the fixing shaft, and a stop rod is slidably inserted on the fixing plate.

[0017] Furthermore, one end of the tension spring is connected to the pulling end of the stop rod, and the other end is connected to the fixing plate.

[0018] Furthermore, a locking screw is inserted into one side of the sliding seat, and the end of the locking screw is pressed against the rotating guide plate to prevent the sliding seat from continuing to slide.

[0019] Furthermore, a guide rail is provided on one side of the rotating guide plate, and a slider is provided on one side of the sliding seat. The slider slides in the guide rail, so that the sliding seat slides on the rotating guide plate.

[0020] Further, the sensor includes a pressure sensor for measuring the patient's arterial blood pressure (ABP), central venous pressure (CVP) and pulmonary artery pressure (PAP) in real time.

[0021] Furthermore, the sensor clamping block is a pair of inverted L-shaped plate structures, which are used to clamp the ear-shaped structures on both sides of the sensor to achieve clamping and fixing.

[0022] Furthermore, a label is installed on one side of each set of sensor clamping blocks on the sliding seat, and the corresponding category of the sensor is marked on the label.

[0023] One of the technical solutions of the utility model is to provide a method for fixing a movable sensor, which is implemented using the device and includes the following steps:

[0024] During operation, the clamping screw is screwed to drive the clamping seat to clamp the device on the bed. Since the angle of the rod-shaped structure at the installation position of the clamping bed may not be in a horizontal state, the clamping seat and the fixed seat slide on the rod-shaped structure to make the rotating guide plate in the vertical plane. After the clamping screw is screwed again, the stop rod and the tension spring are pulled to make the rotating guide plate rotate in the vertical plane through the fixed axis. The rotating guide plate is rotated to adjust the rotating guide plate to a vertical angle. The tension spring pulls the stop rod to rub against the fixed axis, increasing the resistance to the rotation of the rotating guide plate. After the position is adjusted, the position of the rotating guide plate remains unchanged.

[0025] Then adjust the height of the sliding seat according to the patient's body position and height and lock it with the locking screw, mark the content with the label, and install the corresponding sensor on the sensor clamping block to complete the installation.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] (1) Flexible clamping and stable fixation: The utility model can be firmly clamped on any rod-shaped structure of the bed, such as the armrest, by screwing the clamping screw. It can effectively adapt even if the part is not in a horizontal state, thus ensuring a stable connection between the device and the bed;

[0028] (2) Three-dimensional spatial adjustment capability: Taking into account the diversity and uncertainty in actual application scenarios, the utility model is designed with a rotating guide plate, which can be adjusted according to the actual inclination angle of the bed armrest. The clamping seat and the fixed seat are first clamped so that the rotating guide plate is in a vertical plane, and then the rotating guide plate is rotated by the fixed axis to make the rotating guide plate reach a vertical state, thereby enhancing stability. At the same time, the friction force generated by the tension spring and the stop rod on the fixed axis increases the resistance of the rotating guide plate during rotation. After adjusting to the appropriate position, it can effectively prevent the device from rotating accidentally, thereby ensuring that the position of the device is permanently stable.

[0029] (3) Personalized adaptation: The sliding seat can be flexibly adjusted up and down according to the different heights and body positions of patients, and can be locked by locking screws, so as to achieve accurate positioning of patients of different body types and improve the accuracy of monitoring data;

The corresponding cables of the pressure sensor are not easy to get tangled together, which greatly improves work efficiency and reduces the possibility of operation errors;

[0031] (5) In summary, the design and working process of the device of the utility model fully consider the actual needs in the intensive care unit, integrating flexibility, stability and humanization, and effectively solving the problems of difficult sensor fixation, inaccurate positioning, chaotic cable management, etc. in the current clinical environment, greatly optimizing the workflow of the intensive care unit and the quality of patient monitoring.

[0039] Example:

[0040] A movable sensor fixture, such as Figure 1 and Figure 2 As shown, it includes a fixing seat 1, a clamping seat 2 is slidably installed in the fixing seat 1, and the fixing seat 1 and the clamping seat 2 clamp the installation position of the bed;

[0041] A clamping screw 3 is inserted into the upper part of the fixing seat 1, and the lower end of the clamping screw 3 is rotatably connected to the clamping seat 2;

[0042] The fixing seat 1 and the clamping seat 2 are both provided with arc-shaped grooves on their contact surfaces, and the arc-shaped grooves clamp the rod-shaped structure of the installation position of the bed;

[0043] A fixed shaft 4 is installed on the right side of the fixed seat 1, and a rotating guide plate 5 is rotatably installed on the fixed shaft 4;

[0044] A stop rod 6 is slidably inserted on the left upper part of the rotating guide plate 5, and a tension spring 7 is sleeved on the stop rod 6. The tension spring 7 pulls the stop rod 6 to squeeze the fixed shaft 4 to prevent the rotating guide plate 5 from continuing to rotate;

[0045] A fixed plate is provided on the left upper part of the rotating guide plate 5, and a stop rod 6 is slidably inserted on the fixed plate;

[0046] The upper end of the tension spring 7 is connected to the upper end of the stop rod 6, and the lower end is connected to the fixed plate;

[0047] The rotating guide plate 5 is slidably sleeved with a sliding seat 8;

[0048] A locking screw 9 is inserted into one side of the sliding seat 8, and the inner end of the locking screw 9 is pressed against the rotating guide plate 5 to prevent the sliding seat 8 from continuing to slide;

[0049] A guide rail is provided on one side of the rotating guide plate 5, and a slider is provided on one side of the sliding seat 8. The slider slides in the guide rail, so that the sliding seat 8 slides on the rotating guide plate 5;

[0050] A plurality of sensor clamping blocks 10 for clamping sensors are mounted on the sliding seat 8. In this embodiment, three groups are preferred, which respectively clamp pressure sensors for measuring the patient's arterial blood pressure (ABP), central venous pressure (CVP) and pulmonary artery pressure (PAP) in real time.

[0051] The sensor clamping block 10 is a pair of inverted L-shaped plate structures, which are used to clamp the ear-shaped structures on both sides of the sensor to achieve clamping and fixing;

[0052] A label 11 is installed on the sliding seat 8 at one side above each set of sensor clamping blocks 10 , and the label 11 is marked with the corresponding category of the sensor.

[0053] A method for fixing a movable sensor is implemented using the above device, and the specific steps are as follows:

[0054] During operation, the device is clamped on the bed by screwing the clamping screw 3 to drive the clamping seat 2. Since the rod-shaped structure of the installation position of the clamping bed, such as the angle of the armrest, may not be in a horizontal state, the clamping seat 2 and the fixed seat 1 slide on the armrest so that the rotating guide plate 5 is in a vertical plane. After the clamping screw 3 is screwed again, the stop rod 6 and the tension spring 7 are pulled so that the rotating guide plate 5 can rotate in the vertical plane through the fixed shaft 4. The rotating guide plate 5 is rotated to adjust the rotating guide plate 5 to a vertical angle. The tension spring 7 pulls the stop rod 6 to rub the fixed shaft 4, thereby increasing the resistance to the rotation of the rotating guide plate 5. After the position is adjusted, the position of the rotating guide plate 5 remains stationary.

[0055] Then, according to the patient's body position and height, adjust the height of the sliding seat 8 and lock it through the locking screw 9, mark the content through the label 11, and install the corresponding sensor on the sensor clamping block 10 to complete the installation.

[0056] The principle and effect of the above device are as follows:

[0057] Flexible clamping and adaptive adjustment: The device of this embodiment firstly uses the driving principle of the clamping screw 3, and by screwing the clamping screw 3, the clamping seat 2 is tightly attached and fixed to the rod-shaped structure of the bed, such as the armrest, so that a firm clamping can be achieved even if the armrest is not in a horizontal state, which reflects the good adaptability of the device to different environmental conditions;

[0058] Three-dimensional directional stabilization mechanism: A rotating guide plate 5 is arranged inside the device of this embodiment. When clamped on a non-horizontal rod-shaped structure, the clamping seat 2 and the fixed seat 1 first ensure that the rotating guide plate 5 is in a vertical plane after clamping, and then the stop rod 6 is manually pulled and the tension spring 7 is pulled to allow the rotating guide plate 5 to rotate through the fixed shaft 4. The rotating guide plate 5 can be manually rotated to a vertical angle, and the mechanical mechanics principle is cleverly used to cooperate with the tension spring 7 to pull the stop rod 6 and the fixed shaft 4 to generate friction, thereby increasing the rotation resistance of the rotating guide plate 5, ensuring that the device can remain stable and motionless after the position adjustment is completed, and avoiding malfunction caused by external force or patient movement;

[0059] Height adjustment and locking mechanism: In order to adapt to patients of different heights and body positions, the device of this embodiment is equipped with a sliding seat 8, allowing medical staff to freely adjust the height of the sliding seat 8 according to actual conditions; after the height is adjusted to the right position, the position of the sliding seat 8 can be fixed by the locking screw 9 to ensure that the sensor always remains in the ideal monitoring position of the fourth intercostal space at the mid-axillary line;

[0060] Label guidance and precise installation: The device of this embodiment is provided with clear labels 11 corresponding to the installation positions of different pressure sensors (such as ABP, CVP, PAP). Medical staff only need to refer to the instructions of the labels 11 and install the corresponding sensors on the preset sensor clamping block 10. Due to the standardized fixation of the sensors, the cables of the sensors can be clearly identified from the connection end, so that the installation task can be completed quickly and accurately, which greatly improves the installation efficiency and monitoring accuracy.

[0061] In summary, the device of this embodiment uses a series of sophisticated mechanical transmission and adjustment components to achieve flexible, accurate and stable installation of various sensors in the intensive care unit, effectively solving the problems of messy cables and difficult sensor positioning in the original technology, and improving the management and treatment effects of the intensive care unit.

[0062] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
