1、 Product Overview and Technical Principles

3M Disposable Blood Liquid WarmerThe use of disposable instruments as an important component of modern medical infusion systems is a sterile disposable consumable specifically designed for use with blood liquid thermometers. This product adopts excellent dry heating conduction technology, which tightly adheres the infusion tube or heating bag to the heating plate to achieve safe and rapid heating of blood, plasma, crystalloid fluid, and colloid fluid.

The core working principle of the disposable blood liquid warmer is based on an efficient heat conduction mechanism. When refrigerated blood (usually stored at 2-6 ℃) or room temperature liquid flows through the dedicated tubing inside the device, the dry heating device evenly transfers heat to the liquid through a disposable heating bag or tubing, causing its temperature to rise to near normal body temperature (35-37 ℃) in a short period of time, effectively avoiding the patient's temperature drop and related complications caused by the input of low-temperature liquid.

This product adopts a unique three chamber tube design or low resistance flow channel design to ensure uniform temperature distribution of the liquid during the heating process, avoiding local overheating or insufficient heating. At the same time, the temperature monitoring component built into the instrument can provide real-time feedback on the liquid temperature, and with the intelligent microcomputer control system of the temperature controller, precise temperature control can be achieved, with a temperature control accuracy of ± 0.5 ℃ or even higher. This precise temperature control is crucial for preventing blood hemolysis, maintaining blood component activity, and ensuring patient safety.

From the perspective of technological development, blood heating technology has gradually evolved from early water bath heating to modern dry heating technology. Dry heating technology not only avoids the potential risk of cross infection caused by water bath systems, but also has significant advantages such as fast response speed, precise temperature control, and easy maintenance. The disposable blood liquid warmer is a professional consumable developed based on this technology platform, representing the excellent technical level in the current field of blood warming.

2、 Product structure composition and specifications

The disposable device is composed of multiple precision components, and the overall design fully considers the convenience and safety of clinical use. The main structure includes: heating bag (or heating pipeline), intravenous infusion end interface, exhaust valve (or automatic exhaust defoamer), infusion pipeline, filter (equipped on some models), needle free infusion interface, and temperature sensing component.

According to different clinical flow requirements, disposable blood liquid thermometers are usually divided into two series: standard flow type and high flow type:

Standard flow series (such as 24200, 24240, 24250 models):

Flow range: KVO (maintaining venous patency) to 9000ml/hr (150ml/min)

Infusion volume: 39-44ml

Maximum working pressure: 300mmHg (40kPa)

Configuration features: The 24200 model is equipped with a 30 inch infusion tube; The 24240 model is equipped with a 60 inch infusion tube and exhaust valve; The 24250 model is equipped with an extended infusion tube and a needle free standard intravenous infusion interface

High traffic series (such as 24355 type):

Flow range: KVO to 30000ml/hr (500ml/min)

Infusion volume: 150ml

Maximum working pressure: 300mmHg (40kPa)

Configuration features: equipped with dual infusion pins, 150 micron filter drip chamber, needle free and standard intravenous infusion interfaces, automatic exhaust valve, and 60 inch infusion tube, suitable for high-capacity rapid infusion scenarios

All models are made of materials that do not contain DEHP or latex, ensuring patient safety and reducing the risk of allergic reactions. The product is sterilized with ethylene oxide, and the sterile shelf life is usually two years. Each set of instruments is individually packaged, with a packaging specification of 10 sets/box, which facilitates inventory management and traceability of use in clinical departments.

3、 Clinical application and usage scenarios

Disposable blood liquid warmer devices have a wide range of application scenarios in modern medical practice, and their core value lies in preventing hypothermia and related complications, and improving patient prognosis.

In operating room applications, this instrument is an important tool for maintaining patient temperature. Research has shown that inputting 1 liter of room temperature liquid (21 ℃) or 1 unit of refrigerated blood (4 ℃) can cause a decrease in the average body temperature of patients by 0.25 ℃, and this effect is additive. In cases of prolonged surgery or significant blood loss requiring rapid fluid replacement, using a blood liquid warmer and disposable instruments to warm the input fluid can effectively reduce heat loss and maintain normal body temperature in conjunction with other insulation measures.

The role of this device is particularly critical in emergency departments and trauma treatment scenarios. Severe trauma patients often suffer from massive blood loss and hypothermia, known as the 'deadly triad'. At this time, a large amount of warm blood and fluids need to be rapidly infused to stabilize vital signs. The disposable blood liquid warmer can continuously provide warmed blood under high flow conditions (up to 500ml/min), meeting the urgent needs of trauma resuscitation.

In the intensive care unit (ICU), for patients who require long-term intravenous nutrition support or continuous infusion of blood products, this device ensures that the temperature of the infusion fluid is appropriate and reduces stimulation to the patient's circulatory system. In neonatology and pediatrics, due to the weaker ability of children to regulate body temperature, they are more sensitive to the temperature of input fluids. The use of standard flow disposable instruments can accurately control the heating process and ensure the safety of children.

In addition, disposable blood temperature devices also play an irreplaceable role in dialysis rooms, transfusion departments, oncology departments, and pre hospital emergency situations (including ambulance and helicopter medical rescue). The portable design makes it suitable for various medical environments, including outdoor rescue scenarios with limited power supply.

4、 Product advantages and security guarantee

Compared with traditional infusion methods and other heating schemes, disposable devices for blood liquid warming devices have significant product advantages:

Preventing cross infection: As a disposable product, this device fundamentally eliminates the risk of cross contamination caused by repeated use. Each patient uses independently packaged new equipment that meets the high standards of modern hospital infection control requirements.

Accurate temperature control guarantee: With the combination of instruments and temperature controllers, precise temperature setting can be achieved within the range of 28 ℃ to 41 ℃, with a typical temperature control accuracy of ± 0.5 ℃. The triple temperature protection mechanism (including high temperature alarm, over temperature alarm, and sensor fault alarm) ensures the safety and reliability of the heating process.

Convenient and efficient operation: Disposable instruments adopt a detachable and ready to use design, without the need for cleaning, disinfection, or pretreatment, significantly saving medical staff operation time. The instrument is easy to install and can usually be set up within 30 seconds. It can only be inserted into the thermometer in the correct direction, avoiding operational errors.

Material safety and reliability: The product is made of medical grade polymer materials and does not contain DEHP (phthalates) or latex, avoiding potential harmful substance precipitation and allergic reactions. All materials have passed biocompatibility testing to ensure safe contact with blood and medication.

Strong flow adaptability: From pediatric low-speed infusion to trauma emergency high flow infusion, this device series can cover a wide flow range from KVO to 30000ml/hr, meeting the needs of different clinical scenarios. The low resistance flow channel design ensures stable heating performance even under high flow conditions.

Maintenance cost optimization: Adopting dry heating technology, there is no need to replace the water bath or treat wastewater. The main unit of the temperature controller is easy to maintain, requiring only one cleaning and maintenance per year. Compared with traditional water bath heating equipment, it significantly reduces maintenance costs and workload.
