Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a temperature-controllable infusion auxiliary device. Background Art

[0002] During clinical infusions, especially during field rescue and treatment, some medications or special circumstances require maintaining the temperature of the solution to ensure efficacy and patient safety. For example: 1. Blood products (red blood cell suspensions, platelets, plasma, cryoprecipitate, etc.) must be rewarmed to near body temperature (approximately 37°C) before infusion. When large-volume blood transfusions are required for field emergency care, hypothermia and vasoconstriction must be avoided, as direct infusion of refrigerated blood products may induce shivering or arrhythmias. 2. Biologics (monoclonal antibodies (such as rituximab), interferons, certain vaccines, intravenous immunoglobulin (IVIG), etc.) must be maintained at room temperature (20-25°C) or near body temperature during infusion. This is because high or low temperatures can disrupt protein structure and affect efficacy. 3. Intravenous nutrition solutions (such as lipid emulsions) must be maintained at near body temperature (approximately 30-37°C) during infusion. This is to minimize phlebitis and patient discomfort caused by cold stimulation, and lipid emulsions tend to coagulate at low temperatures, potentially affecting stability. 4. Enzyme drugs (such as asparaginase and trypsin) must be infused at room temperature, avoiding excessive cooling or heating. This is because extreme temperature fluctuations may cause enzyme loss. 5. Heated infusions are required in special circumstances, such as: large-volume infusions in surgical or trauma patients, which require warming to approximately 37°C to prevent hypothermia; controlled infusion temperature in pediatric and neonatal patients, whose body temperature regulation is poor; and rewarming treatment for patients in shock or hypothermia.

[0003] After searching, the Chinese patent with publication number CN112843393A discloses a medical infusion heating auxiliary device, and the disclosed content is: the auxiliary device includes a liquid-filled thermal conductive bag and an electric control box installed in the middle of the front end surface of the liquid-filled thermal conductive bag, a heat conductive plate is installed in the middle of the inner side of the liquid-filled thermal conductive bag, and a heating resistance wire with a wavy structure is provided on the inner side of the heat conductive plate.

This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0021] Reference Figures 1-6 The figure shows a preferred embodiment of the present invention.

[0022] Example 1: The solution of Example 1 of the present invention provides a temperature-controllable infusion auxiliary device, see Figure 1-Figure 3 As shown, it includes a deformable wrapping body, which is used to wrap the four sides and bottom of the infusion bag or infusion bottle, so as to facilitate the insulation of the liquid medicine in the infusion bag or infusion bottle; the inner wall of the deformable wrapping body is connected to a long strip near its top, and the long strip is wrapped around the outer wall of the infusion bag or infusion bottle, so as to facilitate the attachment of the wall surface of the outer wall of the infusion bag or infusion bottle. There are multiple flexible sheet-like heating sheets installed at intervals, which are in close contact with the outer wall of the infusion bag or infusion bottle, so as to facilitate the effect of heating the infusion bag or infusion bottle. The maximum temperature rise of the multiple flexible sheet-like heating sheets is stable and does not exceed 40°C, and the maximum temperature of the insulation work will not affect the outer wall of the infusion bag or infusion bottle; The inner wall of the deformable wrapping body is also connected to a long strip 2 near its bottom. The long strip 2 is used to wrap around the outer wall of the infusion bag or infusion bottle to facilitate its adhesion to the outer wall of the infusion bag or infusion bottle. A plurality of flexible sheet-like temperature sensors are installed at intervals on the wall surface to monitor the temperature of the infusion bottle or infusion bag in real time, and the real-time monitored temperature data signal is fed back to the main control chip.

[0023] A semiconductor cooling fin (TEC1-12706) is installed on the inner top surface of the bottom of the deformable package body. The main control chip controls the semiconductor cooling fin to cool down the temperature if the temperature is too high based on the temperature monitoring feedback information, so that the temperature reaches a balance. The design of the semiconductor cooling fin forms a temperature safety guarantee mechanism for the heat preservation work of the device of this application. A display operation control screen is installed on the outer wall of the deformable package body. The display operation control screen integrates the main control chip. The flexible sheet heating sheet, the flexible sheet temperature sensor sheet, the semiconductor cooling fin and the display operation control screen are electrically connected to the main control chip. Through the display operation control screen, on the one hand, real-time heat preservation temperature information can be displayed, and on the other hand, temperature control operations can be performed. After adjusting to the appropriate temperature, a constant heat preservation effect is achieved throughout the entire infusion process.

[0024] At least two fastening straps are connected to the outer wall of the deformable wrapping body at intervals (the material of the fastening straps is similar to the soft packaging material of the current clinical infusion bags, or is a grid-shaped strip). The fastening straps can facilitate the firm binding and fitting between the deformable wrapping body and the infusion bottle or infusion bag.

[0025] In this embodiment, the above-mentioned deformable wrapping body includes a memory alloy frame (made of nickel-titanium alloy NT-SM100) and an elastic memory transparent sleeve (made of transparent rubber, etc.) fixedly sleeved on the outer wall of the memory alloy frame. The memory alloy frame is composed of a plurality of double-ring memory metal frames arranged at longitudinal intervals. Through this design, the deformation of the deformable wrapping body is conveniently realized, so that it can be expanded or reduced in size, which is convenient for accommodating infusion containers of different sizes or forms.

[0026] Among them, the fastening strap adopts Velcro strap, which makes the operation of firm binding more convenient.

[0027] In addition, the aforementioned display and operation control panel is integrated with an audible and visual alarm system. This system consists of a flashing temperature alarm light and a buzzer (≥85dB buzzer + LED warning), which can easily alert patients or medical staff when the temperature is too high or the device malfunctions. The display and operation control panel also integrates a wireless transmission module, which can use a Bluetooth communication module, allowing medical staff to achieve remote monitoring through wireless connection.

[0028] In the solution of this embodiment, an ambient temperature compensation algorithm based on BP neural network is embedded in the main control chip to implement the ambient temperature compensation mechanism and ensure the stability of the device when used outdoors. The architecture of the ambient temperature compensation algorithm based on BP neural network is designed as follows: 1. Input layer design (5 neurons) (1) Ambient temperature (real-time acquisition by DS18B20); (2) Historical temperature change rate (Δt / ΔT, 10s window); (3) Material coefficient of infusion container (glass = 0.8 / PVC = 0.6 / PE = 0.5); (4) Remaining liquid volume (calculated by pressure sensor); (5) Device operating mode (continuous / intermittent, Boolean encoding).

[0029] 2. Hidden layer structure Double hidden layer design, using ReLU activation function: First hidden layer: 8 neurons (empirical formula: √(5×3)+2); Second hidden layer: 6 neurons (to reduce overfitting); 3. Output layer (3 neurons) Linear activation function output: Heating power compensation coefficient (0.5-1.5 times the benchmark); Cooling start threshold offset (±2°C); Sampling frequency adjustment parameters (1-10Hz); The above algorithm training is implemented as follows: 1. Training dataset construction Collect 10,000 sets of clinical environment data: Temperature range: -5℃~45℃ (covering extreme environments); Infusion rate: 10-200 drops / minute; Container type: 12 medical grade materials; Data preprocessing: normalization processing: Min-Max Scaling; Time series feature extraction: sliding window (60s); Outlier elimination: 3σ principle.

[0030] 2. Network training parameters Learning rate: 0.001 (Adam optimizer); Loss function: MSE + L2 regularization (λ=0.01); Batch size: 32; Iterations: 2000 epochs Early stopping mechanism: validation loss does not improve for 5 consecutive times.

[0031] 3. Online learning mechanism Continuous learning after deployment: Incremental update cycle: every 24 hours; New data cache: circular buffer (500 groups); Model update strategy: fine-tune the weights of the last two layers.

[0032] Example 2: The difference between Example 2 of the present invention and Example 1 is that: See also Figure 4-Figure 6 As shown, the deformable wrapping body consists of an elastic memory transparent roll cover and a bottom cover. The bottom of the bottom cover has a through hole for the infusion tube to pass through; the top of the bottom cover is installed with an elastic tie rope. When in use, the elastic memory transparent roll cover is first wrapped around the infusion bottle or infusion bag, and then the bottom cover is put on the bottom and tied with the elastic tie rope.

[0033] Example 3: The solution of Example 3 is based on the solution of Example 1 or Example 2. The difference from Example 1 or Example 2 is that the elastic memory transparent sleeve 11 in Example 1 or the elastic memory transparent roll sleeve 12 in Example 2 is designed to be translucent brown, and a transparent strip is designed longitudinally on the wall to facilitate the infusion and heat preservation of drugs that need to be shielded from light in special scenarios, and the transparent strip can be used to easily penetrate the liquid medicine in the infusion bottle or infusion bag.

[0034] Through the above-mentioned embodiments of the present invention, the infusion auxiliary device is portable and can be deformed and adapted according to the infusion scenario and the situation of the infusion container, so as to be conveniently adapted to the wrapping and insulation of different infusion containers (infusion bags or infusion bottles, etc.), meet the precise temperature control requirements of special drug infusion, and ensure the efficacy of the drugs.

[0035] In addition, the infusion auxiliary device is particularly suitable for the infusion of special clinical drugs and special infusion scenarios. For example, the infusion of certain antibiotics needs to be maintained at a certain temperature range for infusion to achieve the best drug effect. It is also suitable for use in blood transfusion scenarios for wounded soldiers during field operations, because the plasma to be infused is temporarily stored in a blood storage refrigeration for transportation. Before the blood transfusion, the blood bag cannot be immediately infused into the wounded after it is taken out. It needs to be warmed up first. At this time, the blood bag can be wrapped and warmed up by the infusion auxiliary device invented in this application, which can achieve its warming effect. Therefore, the infusion auxiliary device of the present invention can not only assist in achieving constant temperature maintenance of infusion, but also realize the rewarming operation of special infusion supplies in clinical practice.

[0036] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
