Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a connecting tube fixing mechanism for a critical care ventilator. Background Art

[0002] In the intensive care unit (ICU) setting, many patients need to rely on a ventilator to maintain their life due to impaired or lost respiratory function. These conditions may include acute respiratory distress syndrome (ARDS), acute exacerbation of chronic obstructive pulmonary disease (COPD), pneumonia, etc. A ventilator helps the patient breathe by providing mechanical ventilation support until their ability to breathe on their own is restored.

[0003] The pipe structure connecting the patient and the ventilator lacks a limiting structure, resulting in the risk of the pipe falling off under its own gravity and external forces. Currently, simple fixing methods such as tapes and cable clamps are used to fix the ventilator connecting tube. This type of structure also has insufficient stability and low functionality when in use.

[0004] To this end, we provide a critical care ventilator connecting tube fixing mechanism to solve the above-mentioned problems. Summary of the invention

[0011] The present invention is further configured such that a limiting sleeve is fixed on the inner side of the support plate, wherein the limiting sleeve is an integrally formed structure and is provided with a plurality of circle holes, and the ventilator connecting tubes are correspondingly inserted into the circle holes.

[0012] The present invention is further configured such that the circle hole of the limiting sleeve corresponds to the elastic clamp, and the initial positions of the plurality of elastic clamps are different from the corresponding positions of the circle hole.

[0034] The base 100 includes a base 101, a power connection terminal 102 and a signal terminal 103 symmetrically embedded on the periphery of the base 101, a cover 104 fixed to the end of the base 101, a bottom plate 105 sealed and installed at the bottom of the base 101, and a magnetic block 106 fixed to the lower side of the bottom plate 105, and the magnetic block 106 allows the device to be firmly attached to a metal surface, such as a bed frame;

[0035] The connecting pipe limiting mechanism 200 includes a support plate 201, a transmission plate 202 rotatably arranged in the central area of ​​the support plate 201, a connecting rod 207 matched with the hole position at the end of the transmission plate 202, a traction rod 203 movably connected to the end of the connecting rod 207, an elastic clamp 204 fixed to the end of the traction rod 203, and a protective pad 205 fixed to the concave area of ​​the edge of the support plate 201 through a fastener, a balancing sleeve 208 is arranged on the outside of the end of the traction rod 203, and the balancing sleeve 208 is fixed to the branch end of the support plate 201, and the arc-shaped inner wall of the protective pad 205 is embedded with a pressure sensing patch, and the pressure sensing patch is located between the pipe wall of the ventilator connecting pipe and the protective pad 205, and a plurality of the pressure sensing patches are connected to the signal end 103;

[0036] The support plate 201 supports other components and serves as the basis of the connecting tube limiting mechanism 200. The transmission plate 202, the connecting rod 207, the traction rod 203 and the elastic clamp 204 are driven by the motor 209 to form a linkage system for adjusting and fixing the position of the ventilator connecting tube; the balance sleeve 208 ensures the stability of the traction rod 203 when moving; the motor 209 drives the eccentric piece 210 to rotate, thereby driving the transmission plate 202 to move to achieve precise position adjustment, and the limiting sleeve 206 is provided with a plurality of loop holes for passing and fixing ventilator connecting tubes of different diameters. The loop holes correspond to the elastic clamp 204, and different initial positions of the elastic clamp 204 can be adjusted to meet different usage requirements; the protective pad 205 has an embedded pressure sensing patch to monitor the degree of compression of the connecting tube on the patient and transmit the data to the signal terminal 103;

[0037] The elastic clamp 204 is provided with a soft pad inside, and the surface of the soft pad is provided with an anti-slip texture to ensure that the connecting pipe is firmly and gently clamped.

[0038] Specifically, the connecting pipe limiting mechanism 200 also includes a motor 209, which is located inside the hood 104 and fixed to the inner center of the support plate 201. The end of the output shaft of the motor 209 is connected to one end of an eccentric member 210, and the other end of the eccentric member 210 is connected to the transmission plate 202.

[0039] Furthermore, the signal end 103 is integrated with an audible and visual alarm, and the signal end 103 has a built-in execution module connected to the motor 209, the base 101 has a built-in power module, the power module is connected to the power connection end 102 and the signal end 103, and the signal end 103 has a built-in wireless communication module, and the signal end 103 establishes a two-way communication link with the external monitoring end via the wireless communication module;

The built-in execution module is connected to the motor 209, and the working state of the motor 209 is automatically adjusted according to the sensor data. The built-in wireless communication module establishes a two-way communication link with the external monitoring equipment to achieve real-time data transmission.

[0042] The ventilator connecting tube fixing mechanism proposed in this technical solution for use in an intensive care environment is intended to improve the safety and comfort of patients through automated and intelligent design, while reducing the workload of medical staff; the specific use steps of the ventilator connecting tube fixing mechanism are:

[0043] 1. Preparation and installation: Place the base 100 at a suitable location, use the magnetic block 106 to firmly adsorb it on the bedside or other metal surface, and turn on the device.

[0044] 2. Connect the ventilator pipeline: Pass the ventilator connecting tube through the circle hole on the limiting sleeve 206, select the appropriate circle hole according to the needs, and ensure that the connecting tube is in the best position.

[0045] 3. Adjustment and positioning: Start the motor 209 through the control system or manually. The motor 209 drives the transmission plate 202 to rotate through the eccentric piece 210, thereby driving the connecting rod 207 and the traction rod 203 to move, and finally the elastic clamp 204 applies appropriate pressure to the connecting pipe. Observe the information fed back by the pressure sensor patch in the protective pad 205 to ensure that the pressure is moderate and evenly distributed.

[0046] 4. Monitoring and maintenance: The wireless communication module built into the signal terminal 103 is used to monitor the status of the connecting tube in real time. When an abnormal situation is detected (such as being too tight or loose), the sound and light alarm will automatically activate to remind medical staff. Regularly check the working conditions of all components to ensure their normal operation. The signal terminal 103 is also used to feedback the power of the built-in power module in the base. When the power is low, feedback will be given immediately to charge it through the power connection terminal 102.

[0047] 5. End of use: When the device is no longer needed, turn off the power first, then carefully remove the connecting tube, clean and disinfect all contact parts, and prepare for the next use.

[0048] During the above operation steps, the pressure sensing patch monitors the pressure of the connecting tube in real time to avoid skin damage caused by excessive pressure; the automated pressure adjustment mechanism reduces the risk of human operating errors; the soft padding and anti-slip texture design reduce the pressure on the patient's skin and improve wearing comfort; the wireless communication module allows remote monitoring, reducing the need for medical staff to frequently check the equipment; automated adjustment reduces manual intervention, allowing medical staff to focus on more important care tasks.
