Description

Technical Field

[0001] This utility model relates to the field of infusion tube heating technology, and in particular to an infusion stand with temperature control function. Background Technology

[0002] In clinical intravenous infusion, the temperature of the medication has a significant impact on patient comfort and therapeutic efficacy. Traditional infusion stands only suspend the infusion bottle and cannot effectively regulate the temperature during the infusion process. Especially in cold seasons or special departments, direct injection of cold medication can easily cause discomfort such as vasoconstriction and chills, and may even affect the efficacy of the drug. Therefore, there is an urgent need in clinical practice for a device that can heat the infusion tubing or infusion fluid to achieve constant-temperature infusion.

[0003] Currently, some heated infusion devices exist, typically using heating bags, thermostats, or electronic heating elements. While these can raise the liquid temperature to some extent, they suffer from drawbacks such as bulky structure, inconvenient use, inaccurate temperature control, and inability to adjust the temperature in real time. Furthermore, some devices employ inappropriate heating methods for the tubing, easily leading to uneven heating and overheating that can damage the infusion tubing, thus reducing the device's practicality and safety.

[0004] In addition, existing IV stands are generally fixed structures with inflexible height adjustment methods, which cannot flexibly adjust the height of the IV bag according to the patient's position or medical environment, affecting the convenience of use and medical efficiency, especially in the case of multiple IV bags or bunk beds, making the operation cumbersome.

[0005] For example, patent number CN205307500U describes an infusion stand with temperature control function, including a base and a support. The base has casters at its lower end, and the support has a hook at its top. The support is mounted on the base. It also includes a heating clip and a temperature control device. The heating clip includes a fixing clip, a heating unit, and a temperature transmitter. The temperature control device includes a housing, a temperature adjustment unit, an alarm unit, and a manual alarm button. The housing contains a circuit board with a signal conditioning circuit, a microcontroller, a power module, a communication interface, and a wireless communication module. This invention, through its temperature control device, allows medical staff to adjust the heating temperature according to the patient's different physical conditions. Furthermore, because the temperature control device has a wireless communication module, medical staff can remotely monitor the heating temperature using a handheld device or a monitoring computer. If an abnormal temperature is detected, rapid action can be taken to ensure the patient's safety. While the above-mentioned technical solutions can achieve heating of the infusion pipeline, the size limitation of a single heater restricts the heating time of the liquid inside the pipeline. Directly raising the heater temperature to a high level can easily cause the infusion pipeline to soften or deform due to heat. Therefore, the heating effect of the above-mentioned technical solutions cannot meet the requirements for raising the temperature of the liquid inside the infusion pipeline; furthermore, the above-mentioned technical solutions cannot quickly and conveniently suspend and remove the infusion bottle.

[0006] To address the aforementioned issues, this invention provides an infusion stand that integrates height adjustment and temperature control, and features a temperature control function. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an infusion stand with temperature control function.

[0008] The purpose of this utility model is achieved as follows: an infusion stand with temperature control function includes a support frame. Multiple placement racks are movably mounted on the upper end of the support frame. Multiple heaters are detachably mounted on the upper part of the support frame. Each heater includes a fixed base. A strap is provided on the rear side of the fixed base and is detachably fixed to the support frame. A rotating groove is provided on the right side of the front part of the fixed base. A clamping plate is rotatably mounted in the rotating groove. An arc-shaped groove is provided on the left side of the clamping plate and the right side of the rotating groove. A heating plate is provided in the lower part of the arc-shaped groove, and a temperature sensor is provided in the upper part of the arc-shaped groove.

[0009] Furthermore, both the clamping plate and the upper front side of the fixing base are provided with transverse slots, which separate the heating plate and the temperature sensor.

[0010] In use, the support frame is placed near the location where infusion is needed. Holding the limiting block, the pull rope is pulled downwards, causing the lifting rod to move downwards, thus moving the placement frame downwards. This downward movement of the placement frame facilitates the hanging of infusion bottles. After the placement frame has moved to the appropriate position, the limiting block is placed in the limiting groove. The magnet in the limiting groove attracts the limiting block, preventing it from moving up or down and thus limiting its position. The limiting groove, combined with the upper surface of the limiting groove, provides secondary limiting of the limiting block, preventing it from moving upwards and escaping the magnet's limit under the spring force below the lifting rod. After the infusion bottle is hung, the limiting block is removed from the limiting groove. Releasing the limiting block allows the placement frame to move upwards along the moving groove under the spring force, thereby moving the infusion bottle upwards as well.

[0011] The infusion tubing is then clamped between the fixed base and the clamping plate. The fixed base and clamping plate are rotatably connected and equipped with a torsion spring. Under no external force, the inner side of the clamping plate fits against the fixed base; under external force, the clamping plate rotates relative to the fixed base, facilitating the placement of the infusion tubing between the fixed base and the clamping plate. When placing the infusion tubing, due to the inclined structure between the fixed base and the front side of the clamping plate, slightly pressing inwards towards the area between the clamping plate and the fixed base will rotate the clamping plate, thus placing the infusion tubing into the arc-shaped groove between them.

[0012] The temperature of the infusion pipeline is detected by a temperature sensor. When the temperature of the infusion pipeline is transmitted to the controller, if the temperature is lower than the set range, the controller controls the heating plate to heat the side wall of the infusion pipeline, thereby raising the temperature of the liquid in the infusion pipeline.

[0013] After the liquid is heated for the first time, a similar heater is installed below. The temperature sensor on the heater detects the temperature of the infusion pipeline after heating. When the temperature of the infusion pipeline continues to be lower than the set range value, the controller still controls the heating plate to heat the infusion pipeline.

[0014] Multiple heaters can be installed on the support frame as needed. However, due to the size limitations of a single heater, the heating time for the liquid in the infusion pipeline is limited. If the heating temperature of the heater is directly raised to a high level, the infusion pipeline may soften or deform due to heat. To solve the above problems, this application installs multiple heaters at a heating temperature that does not affect the deformation or softening of the heating pipeline, and simultaneously monitors the temperature of the infusion pipeline to heat it to a specified temperature range, thereby increasing the temperature of the liquid inside the infusion pipeline.

[0015] Beneficial effects: This utility model has the following technical effects when used:

[0016] 1. Achieve precise temperature control and improve infusion comfort: By installing a heating plate and temperature sensor between the clamp and the fixing seat, the temperature of the infusion tubing can be monitored in real time, and heating can be activated in time when the temperature is lower than the set range, ensuring that the infusion fluid is maintained within a suitable temperature range and avoiding patient discomfort caused by excessively cold fluid.

[0017] 2. Multi-point heating design to avoid local overheating: Multiple heaters can be installed on the support frame, and multiple heating positions can be monitored in real time to avoid softening and deformation of the infusion pipeline due to single-point overheating, thereby improving the safety and reliability of the system.

[0018] 3. The clamp structure is reasonably designed, making pipeline installation more convenient: The clamp plate and the fixed seat are connected by a torsion spring and have an inclined structure, which allows the infusion pipeline to automatically enter the arc-shaped clamping groove under slight pressure. The operation is simple and the clamping is stable, improving the efficiency of clinical application.

[0019] 4. Flexible height adjustment and stable positioning of the infusion stand: The magnetic attraction limiting mechanism and spring return structure work together to achieve free adjustment and stable positioning of the height of the infusion stand, meet the infusion height requirements of different patients or clinical scenarios, and are easy to operate and highly stable.

[0020] In summary, this invention improves infusion comfort, safety, and ease of use, and has promising prospects for clinical application. Attached Figure Description

[0027] Example 1, such as Figure 1-4As shown, the purpose of this utility model is achieved as follows: an infusion stand with temperature control function includes a support frame 1; multiple placement racks 3 are movably mounted on the upper end of the support frame 1; multiple heaters 2 are detachably mounted on the upper part of the support frame 1; the heaters 2 heat the infusion pipeline; each heater 2 includes a fixing seat 202; a strap 201 is provided on the rear side of the fixing seat 202; the strap 201 is detachably fixed to the support frame 1; a rotating groove is provided on the right side of the front part of the fixing seat 202; a clamping plate 203 is rotatably mounted in the rotating groove; an arc-shaped groove is provided on the left side of the clamping plate 203 and the right side of the rotating groove; a heating plate 205 is provided in the lower part of the arc-shaped groove; and a temperature sensor 204 is provided in the upper part of the arc-shaped groove.

[0028] Both the clamping plate 203 and the fixing seat 202 have horizontally opened strip grooves on the upper front side. The strip grooves separate the heating plate 205 and the temperature sensor 204, so as to avoid the heating temperature of the heating plate 205 being transmitted to the temperature sensor 204 through the clamping plate 203, the fixing seat 202, etc., which would affect the temperature detection value of the infusion pipeline by the temperature sensor 204.

[0029] The clamping plate 203 and the fixed base 202 are rotatably connected, and a torsion spring is provided between the clamping plate 203 and the fixed base 202. The way the torsion spring is set between the clamping plate 203 and the fixed base 202 is the prior art, which is a simple clamping connection relationship and is not technically limited. Other connection methods can also be adopted as needed to realize the clamping connection structure between the clamping plate 203 and the fixed base 202.

[0030] The support frame 1 has a lifting groove in its upper part. Multiple movable grooves are formed on the support frame 1 above the lifting groove. The placement rack 3 is located within these movable grooves and can move vertically. A lifting rod 8 is also movable vertically within the lifting groove and is fixedly connected to the upper end of the placement rack 3. A spring 9 is installed within the lifting groove, with its two ends connected to the lower end of the lifting rod 8 and the bottom of the lifting groove, respectively. A fixing plate 4 is fixedly installed at the upper end of the lifting rod 8 and is located vertically within the movable groove. A pull rope 5 is connected to the lower end of the fixing plate 4. A limit block 6 is connected to the lower end of the pull rope 5. Multiple magnets 7 are provided on the upper side of the support frame 1. The limit block 6 is made of magnetic material, and the limit block 6 and magnets 7 can attract each other. The magnets 7 are arranged vertically. Multiple limit grooves are formed on the upper side of the support frame 1, and the magnets 7 are located within these limit grooves. A placement groove is formed on the upper surface of the placement rack 3, allowing for easy hanging of infusion bottles, etc.

[0031] In use, the support frame 1 is placed near the location where infusion is needed. Holding the limiting block 6, the pull rope 5 is pulled downwards, causing the lifting rod 8 to move downwards, thus moving the placement frame 3 downwards. This downward movement of the placement frame 3 facilitates the hanging of infusion bottles, etc. After the placement frame 3 has moved to the appropriate position, the limiting block 6 is placed in the limiting groove. The magnet 7 in the limiting groove attracts the limiting block 6, preventing it from moving up or down and thus limiting its position. The limiting groove, combined with the upper surface of the limiting groove, provides secondary limiting of the limiting block 6, preventing it from moving upwards and escaping the magnet 7's limitation under the spring force of the spring 9 below the lifting rod 8. After the infusion bottle is hung, the limiting block 6 is removed from the limiting groove. Releasing the limiting block 6 allows the placement frame 3 to move upwards along the moving groove under the spring force of the spring 9, thereby moving the infusion bottle upwards.

[0032] The infusion tubing is then clamped between the fixing base 202 and the clamping plate 203. The fixing base 202 and the clamping plate 203 are rotatably connected and equipped with a torsion spring. Under no external force, the inner side of the clamping plate 203 fits against the fixing base 202. Under external force, the clamping plate 203 rotates relative to the fixing base 202, which facilitates the placement of the infusion tubing between the fixing base 202 and the clamping plate 203. When placing the infusion tubing, because there is an inclined structure between the front sides of the fixing base 202 and the clamping plate 203, slightly pressing inwards towards the position between the clamping plate 203 and the fixing base 202 will rotate the clamping plate 203, thereby placing the infusion tubing in the arc-shaped groove between them.

[0033] The temperature of the infusion pipeline is detected by the temperature sensor 204. When the temperature of the infusion pipeline is transmitted to the controller, if the temperature is lower than the set range, the controller controls the heating plate 205 to heat the side wall of the infusion pipeline, thereby raising the temperature of the liquid in the infusion pipeline.

[0034] After the initial heating of the liquid, a heater 2 is installed below. A temperature sensor 204 on heater 2 detects the temperature of the infusion pipeline after heating. When the temperature of the infusion pipeline continues to fall below a set range, the controller still controls the heating plate 205 to heat the infusion pipeline. The heating plate 205, temperature sensor 204, and the controller's control of the heating plate 205 and temperature sensor 204 are existing technologies and will not be described in detail. As long as they achieve the functions required by this application, they are not within the scope of protection of this application. Furthermore, the electrical connection method of the aforementioned electrical components is not technically limited and is existing technology.

[0035] Multiple heaters 2 can be installed on the support frame 1 as needed. Due to the size limitation of a single heater 2, the heating time of the liquid in the infusion pipeline is limited. If the heating temperature of the heater 2 is directly raised to a high level, the infusion pipeline may soften or deform due to heat. To solve the above problems, this application installs multiple heaters 2 at a heating temperature that does not affect the deformation or softening of the heating pipeline, and simultaneously monitors the temperature of the infusion pipeline to heat the pipeline to a specified temperature range, thereby increasing the temperature of the liquid in the infusion pipeline.
