Description

Technical Field

[0001] This utility model relates to the medical field, specifically to an emulsion heating device that can enclose the outlet pipe of an enteral nutrition pump. Background Technology

[0002] Enteral nutrition support is an important way to provide nutrition to patients who are unable to eat orally or whose food intake is insufficient. It uses a nutrient pump to deliver nutrient solution through tubing to the patient's gastrointestinal tract. However, the nutrient solution is easily affected by the ambient temperature during delivery. If the temperature is too low (below 35°C), it may irritate the gastrointestinal tract and cause spasms, bloating, or diarrhea. If uneven heating leads to local overheating (above 40°C), it may destroy the active ingredients such as proteins and vitamins in the nutrient solution, or even burn the intestinal mucosa.

[0003] Existing enteral nutrition heating devices mostly employ localized clamp heating or heating wires wrapped around pipes, resulting in poor heating uniformity. Traditional heating wires, in direct contact with the pipes, easily create localized hot spots, leading to large temperature fluctuations in the nutrient solution. Furthermore, traditional heating components have fixed dimensions, making them incompatible with nutrient tubing of different diameters. Direct contact between the heating wire and the nutrient solution tubing poses a risk of electrical leakage due to wear over long-term use, and the lack of a temperature buffering mechanism makes it difficult to cope with instantaneous overheating caused by power fluctuations. Therefore, inventing an emulsion heating device that can wrap around the enteral nutrition pump's outlet tubing to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an emulsion heating device that can wrap around the outlet pipe of an enteral nutrition pump, aiming to improve the problems of traditional heating wires directly contacting the pipe, which easily leads to large temperature fluctuations in the nutrient solution and difficulty in compatibility with nutrient pipes of different diameters.

[0005] This invention is achieved as follows: an emulsion heating device that can enclose the outlet pipe of an enteral nutrition pump, comprising...

[0014] In a preferred embodiment of this utility model, a reinforcing ball is fixedly connected to the tail of the wrapping strip. The reinforcing ball is hemispherical, and the inner wall of the reinforcing ball is correspondingly arranged with the outer wall of the inner bonding plate.

[0015] In a preferred embodiment of this utility model, the heating wire is arranged in a spiral shape within the wrapping strip.

[0016] The beneficial effects of this utility model are: the emulsion heating device that can wrap the enteral nutrition pump outlet pipe obtained by the above design has excellent heating uniformity when in use: the cavity of the buffer wrapping component is filled with a temperature buffer medium, the heat generated by the heating wire is first transferred to the buffer medium, and then evenly conducted to the nutrient pump outlet pipe through the inner bonding plate, avoiding local overheating and ensuring that the temperature of the nutrient solution is stable at about 37°C (close to the human body temperature).

[0017] High adaptability: The wrapping strip has a spiral elastic structure, which can adapt to different diameter feeding tubes (such as 8Fr-14Fr) through its own elasticity.

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an emulsion heating device that can wrap the outlet pipe of an enteral nutrition pump, comprising...

[0029] Heating mechanism 100 includes a control power supply component 110, the end of which is electrically connected to heating component 120; wrapping mechanism 200 includes a buffer wrapping component 210, the heating component 120 is embedded in the interior of the buffer wrapping component 210, the control power supply component 110 is sealed and fixedly connected to one end of the buffer wrapping component 210, the buffer wrapping component 210 wraps around the outer wall of the nutrient pump outlet pipe, the cavity of the buffer wrapping component 210 is filled with a temperature buffer medium, the heat generated by the heating wire 121 is first transferred to the buffer medium, and then evenly conducted to the nutrient pump outlet pipe through the inner bonding plate 213 to avoid local overheating and ensure that the temperature of the nutrient solution is stable at about 37°C (close to human body temperature).

[0030] Please see Figure 3 and Figure 4 The control power supply component 110 includes an input line 111, one end of which is connected to a plug, and the other end of which is electrically connected to a control box 112. The other end of the control box 112 is connected to a power supply line 113. The input line 111 uses a medical-grade anti-pull cable, which can withstand a 5kg pull force without deformation. The plug is a three-pronged medical plug with grounding to avoid the risk of leakage. The outer shell of the control box 112 is made of ABS flame-retardant material and has a built-in overload protection module that automatically cuts off power when the current exceeds 0.5A. The outer side of the end of the power supply line 113 is sealed with a connecting joint 114. The other end of the connecting joint 114 is fixedly connected to a sealing block 115. The connecting joint 114 is made of medical-grade silicone material and can rotate 360° to prevent the power supply line 113 from breaking due to bending. The sealing block 115 is filled with epoxy resin sealant, which forms a waterproof insulation layer after curing, ensuring that the connection between the heating wire 121 and the power supply line 113 does not come into contact with air or liquid.

[0031] The heating assembly 120 includes a heating wire 121, the end of which is fixedly connected to the inside of the sealing block 115. The end of the heating wire 121 is electrically connected to the power supply line 113. The heating wire 121 is made of 7 strands of 0.05mm nickel-plated copper alloy wire, which increases the flexibility by 300%. After repeated bending 10,000 times, the resistance change rate is ≤5%. The surface is covered with a polytetrafluoroethylene insulation layer, which can withstand temperatures up to 260℃, avoiding the risk of short circuit. At the same time, a built-in temperature sensor is embedded next to the heating wire 121, which monitors the heating temperature in real time and feeds it back to the control box 112.

[0032] The cushioning and wrapping assembly 210 includes a wrapping strip 211. The inner wall of the wrapping strip 211 has an arc-shaped groove. One side of the heating wire 121 is embedded in the inner wall of the wrapping strip 211. The depth of the arc-shaped groove matches the diameter of the heating wire 121. An interference fit design is adopted so that the heating wire 121 does not loosen after being embedded. The inner wall of the groove is provided with silicone protrusions of 0.2mm in height, one every 1cm, to further fix the heating wire 121 and prevent displacement during stretching. The wrapping strip 211 is made of platinum-cured medical silicone with a Shore hardness of 50A, which has both flexibility and support, and can be bonded or integrally molded.

[0033] The wrapping strip 211 is spirally designed and elastically wraps around the outer wall of the output tube of the nutrition pump. The spiral pitch is designed to be 1.5-2cm, which can be adjusted by stretching to fit nutrition tubes with a diameter of 3-8mm. The spiral direction is consistent with the winding direction of the nutrition tube to reduce friction when the patient moves. The stretching rate of the wrapping strip 211 is ≤20%, ensuring that it can still spring back to its original shape after stretching without affecting the heating wire 121 and the cavity structure.

[0034] The inner wall of the wrapping strip 211 is provided with an inner bonding plate 213. The cross-section of the wrapping strip 211 and the inner bonding plate 213 is semi-circular. The inner bonding plate 213 is flat and is attached to the outer wall of the nutrient pump outlet pipe. The inner bonding plate 213 is made of 0.3mm thick medical silicone and coated with a nano silver antibacterial coating with an antibacterial rate of ≥99%. The flat design increases the contact area with the nutrient tube by 40%, improving heat transfer efficiency. It is recommended that the side of the inner bonding plate 213 that contacts the nutrient tube be micro-textured to increase friction and prevent slippage.

[0035] There is a cavity between the wrapping strip 211 and the inner bonding plate 213. The cavity is spirally arranged to fit the wrapping strip 211 and the inner bonding plate 213. The cavity is filled with a temperature buffer medium, and the cross-sectional area of ​​the cavity is 5-8 mm². 2The packaging strip 211, with a capacity adaptable to lengths of 10-30cm, uses medical sterile saline solution containing 0.01% benzalkonium chloride as an antibacterial agent, extending its shelf life to 2 weeks. Both ends of the cavity are sealed and connected to a sealing block 115 and a reinforcing ball 212, forming a closed space to prevent leakage. A reinforcing ball 212, hemispherical in shape, is fixedly connected to the tail of the packaging strip 211. The inner wall of the reinforcing ball 212 corresponds to the outer wall of the inner bonding plate 213. The reinforcing ball 212 is made of the same silicone material as the packaging strip 211, with a 0.5mm thick stainless steel sheet embedded inside to enhance structural strength and prevent deformation at the tail due to repeated stretching. A heating wire 121 is spirally integrated within the packaging strip 211, with its spiral direction aligned with that of the packaging strip 211. The central axis of the heating wire 121 coincides with that of the packaging strip 211, ensuring consistent distance from all points in the cavity and further improving the uniformity of heating of the buffer medium.

[0036] Working principle: Power supply and control: Input line 111 is connected to an external power source. The current is regulated by the control box 112 (which has a built-in temperature control module, switch and protection circuit) and then transmitted to the heating wire 121 through the power supply line 113. The control box 112 can adjust the output power according to the preset temperature or real-time monitoring data to ensure that the heating wire 121 generates heat stably.

[0037] Heat transfer: The heating wire 121 is embedded inside the wrapping strip 211 and distributed in a spiral shape. The heat generated is first transferred to the wrapping strip 211 and then diffused to the temperature buffer medium in the cavity between the wrapping strip 211 and the inner bonding plate 213. The buffer medium diffuses the heat evenly through convection, so that the temperature in the cavity tends to be uniform.

[0038] Uniform heating: The inner bonding plate 213 is tightly attached to the outer wall of the nutrient pump outlet pipe. The heat of the buffer medium is conducted to the nutrient solution in the pipe through the inner bonding plate 213, so as to achieve uniform heating throughout the entire section. The spiral wrapping strip 211 and the inner bonding plate 213 ensure that all parts of the outer wall of the pipe are heated evenly, avoiding local temperature differences.

[0039] Sealing and fixing: The sealing and fixing block 115 and the reinforcing ball 212 respectively seal the two ends of the wrapping strip 211 and the inner bonding plate 213 to prevent leakage of the buffer medium; the spiral elastic structure of the wrapping strip 211 makes it tightly wrap around the outer wall of the pipe, preventing the device from shifting due to patient movement and ensuring heating stability.

[0040] It should be noted that the specific model and specifications in this solution need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0041] The power supply and its principle in this solution are clear to those skilled in the art, and will not be described in detail here.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
