Description

Technical Field

[0001] This utility model relates to a heating and heat preservation device for an arm used in intravenous infusion. Background Technology

[0002] Intravenous infusion is a common treatment method in medical care. However, in cold weather, the direct administration of cold medication into the patient's body can cause discomfort and coldness in the arm, pain at the puncture site due to cold stimulation, and even shivering and numbness in weak patients. This not only increases patient suffering but may also affect treatment effectiveness and recovery. Currently, the common solution is to heat the infusion bottle or tubing, but these methods cannot directly warm the patient's arm and do not fundamentally solve the problem of cold medication irritating the arm. Therefore, there is an urgent need for a device that can directly heat and warm the patient's arm to improve the infusion experience and reduce the impact of cold weather on the infusion process. Utility Model Content

[0003] The purpose of this invention is to provide an arm heating and insulation device for intravenous infusion, which addresses the cold stimulation and discomfort caused to the patient's arm by icy intravenous medication in cold weather, and the problem that existing heating methods cannot directly protect the patient's arm.

[0004] To solve the above problems, the technical solution of this utility model is as follows: An infusion arm heating and insulation device includes a water tank and a heating tube. The heating tube has a tubular air bladder inside, and a serpentine hose is attached to the inner wall of the air bladder. The two ends of the serpentine hose are connected to the upper and lower ends of the water tank through an inlet pipe and a drain pipe, respectively. A water pump is installed on the inlet pipe. An electric heater and a temperature sensor are installed inside the water tank. The electric heater and the temperature sensor are connected to a controller.

[0005] Furthermore, it also includes a tray, on which an arc-shaped support piece is fixedly connected, and multiple strap holes are provided on both sides of the tray.

[0006] Furthermore, a baffle is fixedly connected to the front end of the support plate, and a flocked soft pad is glued to the baffle, with a hemispherical protrusion on the soft pad.

[0007] Furthermore, the two ends of the serpentine hose are connected to the inlet pipe and the outlet pipe respectively via valved Luer connectors.

[0008] Furthermore, the water tank is wrapped with insulating cotton.

[0009] Furthermore, a one-way air intake valve is installed at one end of the airbag.

[0010] Furthermore, the water pump is connected to the output of the controller and also includes multiple control buttons connected to the input of the controller.

[0011] The beneficial effects of this invention are as follows: By incorporating a tubular airbag and a serpentine flexible tube within the heating element, and utilizing a water pump to deliver hot water from the tank to the flexible tube, continuous heating of the patient's arm is achieved. Simultaneously, the airbag provides insulation and size adjustment, ensuring a close fit between the device and the arm, effectively alleviating the irritation of cold medication on the patient's arm and significantly improving patient comfort. Furthermore, the device is equipped with a temperature sensor and controller, enabling precise control of the water temperature and ensuring the safety and stability of the heating process. The transparent PVC water tank and level markers allow medical staff and patients to easily monitor the water level and prevent dry burning. The one-way air inlet valve and Luer connector with valve make the device more convenient to use; patients can easily detach the device when needing to use the restroom without affecting normal use. This invention features a simple structure, ease of use, and reliable safety, effectively improving the infusion experience for patients in cold weather, and possesses high practical value and promotional significance.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 5As shown, an infusion arm heating and insulation device includes a water tank 12 and a heating tube 1. A tubular air bladder 3 is installed inside the heating tube 1. The air bladder 3 serves to insulate and adjust its size. A flexible snake 2 is adhered to the inner wall of the air bladder 3. The two ends of the flexible snake 2 are connected to the upper and lower ends of the water tank 12 via an inlet pipe and a drain pipe, respectively. A water pump 17 is installed on the inlet pipe. An electric heater 14 and a temperature sensor 15 are installed inside the water tank 12, and the electric heater 14 and temperature sensor 15 are connected to a controller 16. The water pump 17 is connected to the output of the controller 16. The device also includes multiple control buttons 18, which are connected to the input of the controller 16.

[0016] The controller 16 is a "Keward intelligent temperature control digital display thermostat". The heating temperature is set through the controller 16. The water pump is a miniature DC magnetic water pump of model MP650, the electric heater is a product of model H100, and the temperature sensor 15 is a "DS18B20" sensor. The operating voltage of these electrical components is a safe voltage of 12V. The controller 16 adjusts the water temperature. For example, when the temperature sensor 15 detects that the water temperature is below 40℃, the controller 16 controls the electric heater 14 to start. When the detected temperature is above 45℃, the controller 16 controls the electric heater 14 to stop, so that the water temperature is maintained between 40℃ and 45℃. The multiple control buttons 18 include a heating button, a cooling button, a water pump 17 start / stop button, a heater start / stop button, and a power button.

[0017] During use, the patient passes their arm through the airbag 3, then connects the airbag 3 to the hand-squeezing balloon, inflates the airbag 3, and wraps the serpentine tube around the patient's arm. When the arm feels the serpentine tube touching the skin, inflation stops to avoid affecting blood circulation due to excessive tightness. Then, the water pump 17 is activated, continuously sending hot water into the serpentine tube to heat the patient's arm. Next, medical staff administer intravenous fluids to the back of the patient's hand. Because the arm is wrapped in flowing hot water, it greatly counteracts the discomfort caused by cold medication and prevents numbness.

[0018] At the beginning of the infusion, the system automatically maintains the water temperature at 40-45℃. As the infusion progresses, considering that the patient may gradually adapt or feel discomfort, the patient is allowed to manually adjust the temperature during the infusion process, for example, adjusting it to 41-46℃ to better suit the patient's needs.

[0019] Furthermore, it also includes a tray 7, on which an arc-shaped support plate 9 is fixedly connected, and multiple strap holes 8 are provided on both sides of the tray 7. When the patient is sitting in the seat receiving intravenous infusion, the tray 7 can be fixed to the armrest of the seat through the strap holes 8 using hook and loop fasteners to facilitate the placement of the heating tube 1 by the patient.

[0020] Furthermore, a baffle 6 is fixedly connected to the front end of the support plate 9, and a flocked soft pad 5 is adhered to the baffle 6. The soft pad 5 has a hemispherical protrusion 4. The support plate 9 can limit the heating tube 1, and the soft pad 5 and the hemispherical protrusion 4 help the patient prevent their palm from touching the heating tube.

[0021] Furthermore, the two ends of the serpentine hose 2 are connected to the inlet pipe and the drain pipe respectively via the valved Luer connector 10. When the patient needs to use the toilet, the water pump 17 can be turned off first, and then the two ends of the serpentine hose can be closed through the valved Luer connector 10 to prevent water from flowing out of the serpentine hose. Then the inlet pipe and the drain pipe can be separated from the serpentine hose, allowing the patient to use the heated tube 1 with them.

[0022] Furthermore, the water tank 12 is wrapped with insulation cotton 13. The insulation cotton 13 wraps around the outer walls of the water tank 12 to reduce heat loss.

[0023] Furthermore, a one-way air intake valve 11 is installed at one end of the airbag 3. For example... Figure 4 As shown, Figure 4 This is a cross-sectional view of the one-way air intake valve 11. The one-way air intake valve 11 of this structure consists of an air intake nozzle, a spring and a sealing ball. The one-way air intake valve 11 can be directly connected to the hand-squeezed balloon for inflation. When deflation is required, the sealing ball can be pressed to expel the gas from the balloon 3, making it convenient for the patient to pull out their arm.

[0024] Furthermore, the water tank 12 is made of transparent PVC material. Because the water tank 12 is transparent, patients or medical staff can easily observe the liquid level in the water tank 12, preventing the heater from burning dry.

[0025] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
