Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a thermal insulation heater for transporting ECMO pipelines. Background Art

[0002] ECMO is a process that uses a centrifugal pump to pump out the patient's low-oxygen blood, oxygenates it through an artificial membrane lung, and then delivers oxygen-rich blood to the patient's body. During ECMO treatment, blood needs to be transported through an extracorporeal circulation circuit. Since the circuit is exposed to the ambient temperature, heat will continue to dissipate. Especially when ECMO patients are transferred between hospitals, the transfer time may be as long as more than 4 hours. If the circuit is not effectively heated and insulated, the patient's body temperature will drop, seriously affecting the treatment effect and safety.

[0003] The ECMO tube insulation devices currently used in clinical practice have shortcomings. Traditional insulation devices lack a reliable tube fixing structure. When the vehicle encounters bumps or sudden stops during transportation, it is easy to cause the tube to twist, fold or deform under pressure, which not only affects blood flow, but may also cause local overheating or abnormal pressure.

[0004] Although existing technologies such as CN215194295U disclose an insulation device for ECMO transfer, it only uses a simple insulation pad winding method, which cannot solve core problems such as unstable pipeline fixation, inconvenient length adjustment, and poor heating uniformity. Especially during long-term transportation, the lack of an effective pipeline winding mechanism can easily cause the pipeline to shift, entangle or be compressed, seriously affecting the safety and stability of ECMO treatment. Summary of the Invention

[0005] The purpose of the present invention is to provide an insulation heater for transporting ECMO pipelines in response to the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: a heat preservation heater for transporting ECMO pipelines, comprising:

[0007] Two circular substrates, the two circular substrates are coaxially symmetrically arranged and fixedly connected by a fixed shaft;

[0008] A soft silicone sleeve, wherein the cross-section of the soft silicone sleeve is concave-shaped and the clamping sleeve is arranged on the ECMO tube;

[0009] Two winding discs, the two winding discs are symmetrically arranged and rotatably connected to the two circular base plates, and the soft silicone sleeve passes through the two circular base plates and passes around the two winding discs in an S shape;

[0010] A heating assembly, the output portion of which is embedded in a soft silicone sleeve and is used to heat the ECMO circuit;

[0011] An adjusting component is used to control the rotation of the circular substrate and to wind up the ECMO tube through the winding disk.

[0012] Furthermore, an annular groove matching the soft silicone sleeve is provided on the peripheral side wall of the winding disc, and balls are embedded in the annular groove at equal distances.

[0013] Furthermore, it also includes a positioning component, which includes a positioning plate, two positioning clamps are fixed on the positioning plate, and the fixed shaft is rotatably connected to the positioning plate through a damping bearing.

[0014] Furthermore, the heating component includes an electric heater, a temperature controller, a temperature probe and a thermal wire, the thermal wire is connected to the output end of the electric heater, the thermal wire is embedded in a soft silicone sleeve, the temperature probe is embedded in the soft silicone sleeve, the temperature probe is connected to the temperature controller, and the temperature controller is connected to the electric heater.

[0015] Furthermore, a rectangular slot is provided on the circular base plate, two distance-adjusting moving blocks are slidably connected in the rectangular slot, and the two winding discs are rotatably connected to the two distance-adjusting moving blocks respectively.

[0016] Furthermore, it also includes an adjustment component, which also includes a rotating seat fixedly connected to the circular base plate, a threaded rod rotatably connected in the rotating seat, a motor is installed on the circular base plate, the output end of the motor is interference fit with the threaded rod through a coupling, a linear guide is provided on the circular base plate, a sliding base is slidably connected to the linear guide rail, a threaded sleeve is fixedly connected to the sliding base, the threaded rod and the threaded sleeve are threadedly fitted, and transmission rods are rotatably connected on both sides of the threaded sleeve, and the two transmission rods are rotatably connected to the two distance-adjusting moving blocks respectively away from the threaded sleeve.

[0017] Furthermore, a clamping seat is fixedly connected to the sliding base, and a counterweight block is fixedly connected inside the clamping seat.

[0018] Compared with existing technologies, the advantages of this ECMO pipeline insulation heater are:

[0019] 1. The present invention can quickly fix and connect the ECMO tube through the soft silicone sleeve with a concave cross-section, which is easy to install and disassemble. The soft silicone sleeve has better deformation and wrapping effects, and the ECMO tube can be effectively insulated and heated through the electric heater and thermal wire.

[0020] 2. The present invention provides a circular base plate and a winding disk to coil and store redundant ECMO tubing, preventing the tubing from being folded, twisted, or compressed due to vehicle bumps or sudden stops, which could affect blood flow and cause local overheating or abnormal pressure.

[0021] By setting a counterweight block, the circular base plate always tends to rotate in the direction of reeling in the ECMO tube. Since the rotation of the circular base plate is not locked, when the ECMO tube is pulled, the circular base plate will rotate in the opposite direction to release the ECMO tube, preventing the tube connection from falling due to unstable pulling.

[0022] 3. The present invention provides an adjustment component. When the vehicle is bumpy or stops suddenly, the motor is turned on to move the counterweight away from the center of the circular base. At this time, the center of gravity of the circular base and the counterweight shifts away from the center of the circular base, promoting the rotation of the circular base, further winding the ECMO tube. At the same time, the two transmission rods drive the two distance-adjusting moving blocks to move away from each other, increasing the winding length of the ECMO tube and further preventing the tube from folding, twisting or compression.

[0023] On the contrary, when the vehicle moves normally, the counterweight moves toward the center of the circular base plate. At this time, the rotation tendency and force of the circular base plate are reduced, releasing the soft silicone sleeve to prevent the ECMO tube from being continuously tightened and generating pulling force on its joints. In addition, the two adjustable moving blocks are close to each other, reducing the degree of bending of the ECMO tube when it is entangled, and achieving the effect of dynamically adjusting the curvature of the tube according to the transportation environment.

DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] like Figure 1-7 As shown, a thermal insulation heater for transporting ECMO pipelines includes: two circular substrates 1, a soft silicone sleeve 2, two winding discs 3, a heating component, a positioning component and an adjustment component. The two circular substrates 1 are coaxially symmetrically arranged and fixedly connected by a fixed shaft 10. The positioning component includes a positioning plate 8, on which two positioning clamps 9 are fixed. The fixed shaft 10 is rotatably connected to the positioning plate 8 through a damping bearing. When working, the positioning clamp 9 is clamped and fixed to the side guardrail of the vehicle bed to position the entire device.

[0034] The cross-section of the soft silicone sleeve 2 is a concave structure, and the clamping sleeve is arranged on the ECMO tube. The soft silicone sleeve 2 is made of medical-grade silicone material to form an elastic wrapping layer with a groove cross-section. The groove structure forms a clamping connection with the outer wall of the ECMO tube. The soft silicone sleeve 2 with a concave cross-section can be quickly fixed and clamped with the ECMO tube, which is easy to install and disassemble, and the deformation and wrapping effect of the soft silicone sleeve 2 is better.

[0035] The two winding discs 3 are symmetrically arranged and rotatably connected to the two circular substrates 1. The soft silicone sleeve 2 passes through the two circular substrates 1 and passes around the two winding discs 3 in an S shape. A counterweight 4 is provided on the circular substrate 1, so that the circular substrate 1 is always in a trend of rotating in the direction of ECMO tube winding (direction as shown in FIG. Figure 1 and Figure 3 The redundant ECMO tubes are coiled and stored to prevent the tubes from being folded, twisted or compressed due to vehicle bumps or sudden stops, which may affect blood flow and cause local overheating or abnormal pressure.

[0036] An annular groove 6 matching the soft silicone sleeve 2 is provided on the circumferential side wall of the winding disk 3, and balls 7 are embedded in the annular groove 6 at equal intervals. When the vehicle is bumpy or the pipeline is under stress, the annular groove 6 forms a guiding constraint on the soft silicone sleeve 2 to prevent it from deviating in the radial direction. The array of balls 7 forms rolling friction on the contact surface between the soft silicone sleeve 2 and the winding disk 3. When the pipeline needs to be wound or released, the soft silicone sleeve 2 can rotate with the winding disk 3 to achieve a smooth transition, avoiding local tensile deformation caused by the traditional fixed winding structure.

[0037] The output part of the heating component is embedded in the soft silicone sleeve 2 and is used to heat the ECMO pipeline. The heating component includes an electric heater 11, a thermostat 12, a temperature probe 13 and a thermal wire 14. The thermal wire 14 is connected to the output end of the electric heater 11. The thermal wire 14 is embedded in the soft silicone sleeve 2. The temperature probe 13 is embedded in the soft silicone sleeve 2. The temperature probe 13 is connected to the thermostat 12. The thermostat 12 is connected to the electric heater 11. The electric heater 11 and the thermal wire 14 are used to effectively keep the ECMO pipeline warm and heat it. The temperature probe 13 is used to monitor the real-time temperature of the ECMO pipeline and adjust the heating power of the electric heater 11 through the thermostat 12.

[0038] A rectangular slot 15 is provided on the circular substrate 1, and two distance-adjustable moving blocks 16 are slidably connected in the rectangular slot 15. The two winding disks 3 are rotatably connected to the two distance-adjustable moving blocks 16 respectively. When the distance-adjustable moving blocks 16 slide, the axial distance between the two winding disks 3 changes accordingly. Therefore, when the ECMO pipeline is wound around the winding disks 3, the distance between the winding disks can be changed by adjusting the position of the distance-adjustable moving blocks, thereby changing the length of the pipeline wound between the two winding disks 3.

[0039] The adjustment component is used to control the rotation of the circular base plate 1 and reel in the ECMO tube through the winding disk 3. The adjustment component includes a rotating seat 17 fixedly connected to the circular base plate 1, and a threaded rod 18 is rotatably connected in the rotating seat 17. A motor 19 is installed on the circular base plate 1, and the output end of the motor 19 is interference fit with the threaded rod 18 through a coupling. A linear guide rail 20 is provided on the circular base plate 1, and a sliding base 21 is slidably connected to the linear guide rail 20. A threaded sleeve 22 is fixedly connected to the sliding base 21. The threaded rod 18 and the threaded sleeve 22 are threadedly matched. Transmission rods 23 are rotatably connected on both sides of the threaded sleeve 22. The two transmission rods 23 are rotatably connected to the two distance-adjusting moving blocks 16 away from the threaded sleeve 22.

[0040] When the motor 19 is started, the output shaft drives the threaded rod 18 to rotate through the coupling. Because the threaded sleeve 22 is fixedly connected to the sliding base 21 and the threaded sleeve 22 and the threaded rod 18 form a threaded pair, the rotational motion of the threaded rod 18 is converted into horizontal displacement of the sliding base 21 along the linear guide. During the movement of the sliding base 21, the threaded sleeve 22 fixed thereto drives the transmission rods 23 on both sides to change their angles. The transmission rods 23 transmit horizontal thrust to the two adjustable distance moving blocks 16. The adjustable distance moving blocks 16, under the thrust of the transmission rods, produce synchronous movement in opposite directions along the rectangular slots 15 on the circular base 1, thereby precisely adjusting the spacing between the two winding drums. Compared with the existing technology, traditional ECMO tube insulation devices lack an active adjustment mechanism and cannot dynamically adjust the tube winding state when the vehicle is bumpy. This solution uses a motor-driven threaded transmission mechanism in conjunction with a linear guide and a connecting rod mechanism to achieve automated and precise control of the winding drum spacing. Compared with manual adjustment devices, this structure can respond to changes in the tube state in real time, avoiding tube distortion caused by manual adjustment lag.

[0041] A clamping seat 5 is fixedly connected to the sliding base 21, and the counterweight 4 is fixed in the clamping seat 5. The clamping seat 5 serves as an installation carrier for the counterweight 4. Its rigid structure ensures the connection stability between the counterweight and the sliding base 21, and prevents the counterweight 4 from falling off. The counterweight 4 can be removed and replaced from the clamping seat 5. The counterweight 4 makes the circular base plate 1 always rotate in the direction of ECMO pipeline winding. Since the rotation of the circular base plate 1 is not locked, when the ECMO pipeline is pulled, the circular base plate 1 will rotate in the opposite direction to release the ECMO pipeline, so as to prevent the pipeline connection from falling due to unstable pulling.

[0042] like Figure 4 As shown, when the vehicle is bumpy or stops suddenly, the motor 19 is operated to move the counterweight 4 away from the center of the circular base plate 1. At this time, the center of gravity of the circular base plate 1 and the counterweight 4 is offset in the direction away from the center of the circle, promoting the rotation of the circular base plate 1, further winding the ECMO tube, and at the same time, the two distance-adjusting moving blocks 16 are driven to move away from each other through the two transmission rods 23, thereby increasing the winding length of the ECMO tube and further preventing the tube from being folded, twisted or compressed.

[0043] like Figure 5 As shown, on the contrary, when the vehicle moves normally, the counterweight block 4 moves toward the center of the circular substrate 1. At this time, the rotation tendency and force of the circular substrate 1 are reduced, and the soft silicone sleeve 2 is released to avoid the ECMO tube from being continuously tightened and generating a pulling force at its joints. In addition, the two adjustable moving blocks 16 are close to each other, reducing the degree of bending of the ECMO tube when it is wound, and achieving the effect of dynamically adjusting the curvature of the tube according to the transportation environment.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
