Description

Technical Field

[0001] The present invention relates to a ventilator pipe bracket, and in particular to a support bracket for a ventilator pipe applied in the field of ventilator pipe brackets. Background Art

[0002] Existing ventilator tube support bracket technology mainly focuses on providing a stable and orderly tube layout for ventilators used in hospitals and home care environments. These brackets are designed to reduce bending and twisting of the tubes, ensuring that the ventilator can smoothly deliver air or oxygen to the patient. Traditional brackets are mostly made of metal or plastic materials, and use adjustable clips, hooks and ring structures to adapt to tubes of different lengths and diameters. They are usually installed next to the bed or on the bracket of the ventilator to keep the tubes tidy and reduce restrictions on patient activities. In recent years, with the advancement of technology, some brackets have begun to use lighter and more durable materials, and incorporate modular designs for easy installation and adjustment. Existing brackets still face some challenges, such as the need for further optimization to adapt to more complex medical environments and to improve adaptability to the needs of different patients.

[0003] The specification of Chinese invention patent CN115654253B discloses a pressure-proof ventilator pipe bracket, including a ventilator pipe, with connecting valves at both ends of the ventilator pipe, and also includes an anti-tube-off device and an anti-pressure device. The invention can not only prevent the pipe from falling off due to pulling through the anti-tube-off device, but also offset part of the pulling force to avoid damage to the ventilator pipe. The anti-pressure device can also protect the ventilator pipe to avoid deformation due to pressure.

[0004] The specification of Chinese invention patent CN116036429B discloses a clamping bracket for ventilator pipes. The invention rotates the adjustment cylinder to control the position of the plastic rod through the threaded groove, thereby increasing the overall length of the device and making it easier to support the ventilator pipe. At the same time, by bending two sets of plastic rods, the plastic rods are bent accordingly, thereby facilitating the adjustment of the support angle of the ventilator pipe.

[0005] Traditional stents often lack the ability to regulate the clamping force when clamping ventilator tubes, which can easily cause the tubes to be clamped too tightly or loosely due to external forces. In addition, most of the current traditional stents lack the function of real-time monitoring of the tube status and cannot dynamically adjust the clamping force to cope with the situation where the tube is subjected to external forces. This may cause the tube to be fixed too tightly or too loosely, thereby affecting normal use and posing a threat to patient safety. Summary of the Invention

[0006] In response to the above-mentioned existing technologies, the technical problem to be solved by the present invention is that traditional stents often lack the ability to regulate the clamping force when clamping the ventilator tube, which can easily cause the tube to be clamped too tightly or loosely due to external force. In addition, most of the current traditional stents lack the function of real-time monitoring of the tube status and cannot dynamically adjust the clamping force to cope with the situation where the tube is subjected to external force. This may cause the tube to be fixed too tightly or too loosely, thereby affecting normal use and posing a threat to patient safety.

[0013] As a further improvement of the present application, a protective cover is connected to one end of the support structure close to the stepper motor, and a docking groove matching the stepper motor is provided on the protective cover. When the stepper motor is engaged with the docking groove, the pressure sensor is not under pressure. When the stepper motor is docked with the fixed chuck, the pressure sensor is under pressure.

The pressure sensors on the electromagnet and the rotary chuck are electrically connected to the docking sockets, and the power output end of the stepper motor is installed with a rotary connector that matches the docking joint.

At the same time, it can monitor the tube status in real time and automatically adjust the clamping force, so as to automatically adapt to the situation where the tube is clamped too tightly or too loosely after being subjected to external force.

[0034] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-6 Figure 1 shows a support bracket for a ventilator pipe, comprising a base 1, a fixing bracket optionally mounted on the bottom of the base 1, and the base 1 being fixed to a position such as a bedside, a railing, or a table by a fixing clamp; a support structure 2 being detachably connected to the base 1, and a fixing chuck 3 being detachably connected to the support structure 2; a rotating chuck 4 being connected to the fixing chuck 3; and the cross-sectional dimensions of the fixing chuck 3 and the rotating chuck 4 being the same;

[0037] The support structure 2 is connected to a fixing frame 21 and at least one universal metal hose 22. The top ends of the fixing frame 21 and the universal metal hose 22 are both connected to a stepper motor 5 that matches the fixing chuck 3. The fixing chuck 3 can be connected to the stepper motor 5 on the fixing frame 21 or the universal metal hose 22. The universal metal hose is provided with a bendable integral metal material, and a suitable metal hose in the prior art can be selected by a person skilled in the art for configuration.

[0038] When the fixed chuck 3 is connected to the stepping motor 5 on the fixed frame 21, the fixed chuck 3 is rigidly fixed. When the fixed chuck 3 is connected to the stepping motor 5 on the universal metal hose 22, the fixed chuck 3 is convenient for bending and adjustment.

[0039] The fixed chuck 3 includes a petal main plate 31, and a plurality of pairs of clamping holes are provided on the petal main plate 31; the clamping holes can be used to fix the pipe or place tools;

[0040] The rotating chuck 4 includes a petal sub-disc 41 rotatably connected to the petal main disc 31. The petal sub-disc 41 is provided with an auxiliary hole matching the chuck hole. Pressure sensors are mounted on the inner walls of both the auxiliary hole and the chuck hole. The pressure sensors include thin film pressure sensors, which are laid along the inner walls of the auxiliary hole and the chuck hole. A person skilled in the art can select a suitable thin film pressure sensor from the prior art for installation.

[0041] The petal sub-disc 41 is rotationally connected to the petal main disc 31 via a telescopic shaft 42 , and the telescopic shaft 42 is engaged with the power output end of the stepping motor 5 .

[0042] When the stepper motor 5 is working, it drives the telescopic shaft 42 to rotate, thereby rotating the rotary chuck 4. At this time, the auxiliary hole and the clamping hole on the rotary chuck 4 are staggered, so that the pipe passing through the auxiliary hole and the clamping hole is clamped;

[0043] When the pipe is fixed on the fixed chuck 3 and the rotating chuck 4, when the pressure sensors on the auxiliary hole and the inner wall of the chuck hole detect a pressure change, it means that the pipe fixed in the chuck is subjected to an external force. According to the increase or decrease in pressure, the rotation angle of the rotating chuck 4 is adjusted accordingly to further tighten or loosen the pipe.

[0044] The stepper motor 5 is clamped to one end of the petal main disk 31, and the power output end of the stepper motor 5 passes through the fixed chuck 3 and is clamped to the rotating chuck 4. A docking joint 51 is installed at the top of the power output end of the stepper motor 5, and a pressure sensor is installed on the docking joint 51. The pressure sensor is used to detect whether the docking joint 51 is under pressure.

[0045] A protective cover 6 is connected to one end of the support structure 2 close to the stepper motor 5. The protective cover 6 is provided with a docking groove that matches the stepper motor 5. When the stepper motor 5 is engaged with the docking groove, the pressure sensor is not under pressure. When the stepper motor 5 is docked with the fixed chuck 3, the pressure sensor is under pressure. Only when the pressure sensor detects pressure can the stepper motor 5 be turned on and work.

[0046] During use, the ventilator tube is passed through the clamping hole of the fixed chuck 3, and then the rotating chuck 4 is rotated so that the auxiliary hole and the clamping hole are staggered to clamp the tube; when the tube is subjected to external force, the pressure sensor will detect the pressure change and adjust the rotation angle of the stepper motor 5 according to the pressure change to further clamp or loosen the tube. It is easy to adapt to ventilator tubes of different shapes and sizes.

[0047] At the same time, the fixed chuck 3 of this solution can be optionally docked with the stepper motor 5 on the fixed frame 21 or the universal metal hose 22, so that the fixed chuck 3 can be supported by the rigid fixed frame 21 or the bendable and adjustable universal metal hose 22, which is easy to adapt to different usage environments.

[0048] Second implementation method:

[0049] The same or corresponding components as those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0050] An air cushion layer 32 is laid on the petal main disc 31, and an inflation and discharge hole matching the air cushion layer 32 is installed on the petal main disc 31; a silicone cushion layer is laid on the end of the petal sub-disc 41 close to the fixed chuck 3; the air cushion layer 32 expands after being inflated, which easily increases the surface curvature of the petal main disc 31, making it easier for a single pipe to be wrapped around the petal main disc 31 without being folded at the edge of the hole; and the air cushion layer 32 also plays a certain buffering role, preventing the pipe from being flattened when the rotating chuck 4 and the fixed chuck 3 clamp the pipe.

[0051] The telescopic shaft 42 includes a base column 421 rotatably connected to the petal main disk 31. The outer end of the base column 421 is provided with an isolation ring 422 fixedly connected to the petal main disk 31 and the air cushion layer 32. The base column 421 is provided with a docking hole that matches the power output end of the stepper motor 5. The base column 421 is plugged with a movable column 423 fixedly connected to the petal sub-disk 41.

[0052] An electromagnet is installed in the base column 421 , a permanent magnet matching the electromagnet is installed in the movable column 423 , and a damping layer is laid on the outer wall of the movable column 423 .

[0053] When the movable column 423 of the telescopic shaft 42 is extended, the gap between the fixed chuck 3 and the rotating chuck 4 is widened. At this time, a pipe can be passed through the gap between the fixed chuck 3 and the rotating chuck 4 and engaged with the two engaging holes on the fixed chuck 3. Then, by controlling the operation of the electromagnet, the electromagnet attracts the permanent magnet, and the rotating chuck 4 is moved closer to the fixed chuck 3. At this time, the pipe is clamped and fixed by the rotating chuck 4 and the fixed chuck 3.

[0054] This embodiment achieves convenient and stable clamping of a single ventilator tube.

[0055] The third implementation method:

[0056] The same or corresponding components as those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The third embodiment differs from the first embodiment in that:

[0057] An elastic wire is passed through the telescopic shaft 42, and matching docking sockets and docking plugs are installed on the base column 421 and the docking joint 51 respectively. The pressure sensors on the electromagnet and the rotary chuck 4 are electrically connected to the docking sockets, and the power output end of the stepper motor 5 is installed with a rotary connector that matches the docking joint 51.

[0058] It also includes an adaptive pipe fixing system, which includes a single chip microcomputer installed in the base 1, and the single chip microcomputer is connected to a control module, a monitoring module and a data processing module;

[0059] The monitoring module is used to collect monitoring data from the pressure sensor and the pressure detector; the pressure sensor and the pressure inductor are both connected to the monitoring module signal;

[0060] The data processing module is used to process monitoring data and issue pre-trial control instructions based on the monitoring data;

[0061] The control module is used to control the corresponding device to execute the control instruction, and the multiple stepper motors 5 are all electrically connected to the control module.

[0062] Control switches matching the fixing frame 21 and the universal metal hoses 22 are mounted on the base 1 , and each control switch is used to control the power on and off of the fixing frame 21 and each universal metal hose 22 .

[0063] This embodiment enables the monitoring module in the adaptive pipe-fixing system to continuously collect data from pressure sensors and pressure detectors. This data is then fed into the data processing module for analysis. Based on the analysis results, the data processing module generates corresponding control instructions, which are sent through the control module to the corresponding stepper motor or electromagnet to precisely adjust the pipe clamping force. For example, if the system detects an increase in clamping force due to external force acting on the pipe, the stepper motor's rotation angle will automatically adjust to reduce the clamping force and prevent damage to the pipe.

[0064] Furthermore, this embodiment also enables independent control of the mounting bracket and the universal metal hose via a control switch on the base. Users can selectively turn the power to the mounting bracket and the universal metal hose on or off as needed, allowing them to quickly and easily select whether to activate the automatic control program for the corresponding stepper motor 5.

[0065] In summary, this solution facilitates the firm clamping of the ventilator tube and facilitates the quick switching of flexible support mode or rigid support mode to adapt to the use environment. At the same time, it can monitor the tube status in real time and automatically adjust the clamping force, so as to automatically adapt to the situation where the tube is clamped too tightly or too loosely after being subjected to external force.

[0066] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
