Product Introduction

Braun B. Pump Blood Transfusion DeviceIt is a precision medical device designed specifically for use with infusion pumps or transfusion pumps, mainly used to achieve safe and precise infusion of blood and blood products during clinical transfusion therapy. This product is made of medical grade polymer materials, with good biocompatibility and mechanical strength. It can seamlessly integrate with various infusion pump equipment, ensuring stable flow rate and accurate measurement during blood transfusion, effectively reducing transfusion risks, and improving treatment effectiveness. Pump blood transfusion equipment is widely used in medical settings such as operating rooms, intensive care units, emergency departments, and hematology departments, and is an important auxiliary tool for modern precision blood transfusion therapy.

Product Structure and Composition

The pump blood transfusion device is composed of multiple precision components, and the overall design conforms to ergonomic principles, making it easy for medical staff to operate and use.

The main components include:

Puncture device: made of high-quality stainless steel or hard plastic, used to puncture the sealing port of the blood bag to ensure sterile connection

Drip bucket (dropper): Built in filter that can filter out small clots and impurities in blood, usually equipped with filters of 15 μ m or 170 μ m-260 μ m specifications

Infusion tubing: medical PVC or TPE material hose, with good flexibility and anti twisting performance, suitable for various infusion pumps in terms of pipe diameter specifications

Flow regulator: used to manually adjust the infusion speed as a backup adjustment method for electronic pump control

Pump adaptation section: a hard pipe section designed specifically for infusion pumps, ensuring that the pump body roller or finger shaped compression mechanism can stably clamp and drive the pipeline

Ruhr interface: standard 6:100 cone design, can be reliably connected to intravenous catheters, central venous catheters, etc

Protective cap and packaging: sterile sealed packaging to ensure that the product remains sterile before use

The pipeline design of the pump blood transfusion device fully considers compatibility with the infusion pump. The wall thickness, outer diameter size, and material hardness of the pump adaptation section have been precisely calculated to ensure that the pump body can effectively drive liquid flow and avoid excessive compression that may cause pipeline deformation or damage to blood components.

Working principle and core functions

The core working principle of the pump blood transfusion device is to use the mechanical power of the infusion pump to achieve automated and precise blood transfusion treatment by accurately controlling the flow rate and volume of blood in the pipeline.

The workflow is as follows:

Connection preparation: Insert the puncture device of the pump blood transfusion device into the blood bag, exhaust the air in the pipeline, and correctly install the pump adapter into the slot of the infusion pump

Parameter setting: Medical staff set the target flow rate (usually 5-250ml/h), total infusion volume, and infusion time on the infusion pump based on the patient's condition, blood volume requirements, and blood product type

Pump body drive: The driving mechanism of the infusion pump (finger pump, roller pump, or peristaltic pump) periodically squeezes the adapter section of the pump according to the set parameters, generating stable negative and positive pressures, and pushing blood to flow towards the patient end

Real time monitoring: Modern intelligent infusion pumps are equipped with functions such as bubble detection, pressure monitoring, and blockage alarm, which can be used in conjunction with pump blood transfusion equipment to achieve full process safety monitoring

Complete alarm: When the set infusion volume is completed or the blood bag is emptied, the system automatically alarms and prompts medical staff to replace the blood bag or end the transfusion in a timely manner

Core functional features:

Accurate flow rate control: The error range is usually less than ± 5% to avoid flow rate fluctuations caused by manual adjustment

Uniform infusion: eliminates the problem of uneven flow rate during gravity transfusion, especially suitable for patients who require strict control of transfusion speed

Safety protection: With the various safety monitoring functions of the infusion pump, it effectively prevents risks such as air embolism and pipeline blockage

Reduce hemolysis: Optimized pipeline materials and pump body compression methods to minimize mechanical damage to red blood cells to the greatest extent possible

Fresh frozen plasma, regular frozen plasma, cryoprecipitate

Machine collected platelets, manually separated platelets

Whole blood (rare in modern clinical practice)

Autologous blood recovery (processed by a blood recovery machine)

Special application scenarios:

In procedures such as neonatal blood exchange therapy, extracorporeal circulation pre filling for cardiac surgery, and plasma exchange therapy that require high infusion accuracy, the use of a pump transfusion device in conjunction with a dedicated infusion pump can achieve precise control at the milliliter or even microliter level, which cannot be achieved by traditional gravity transfusion methods.

Product advantages and technical features

Compared to traditional gravity based blood transfusion devices, pump based blood transfusion devices have significant advantages in technical performance and clinical safety.

Core competitive advantages:

1. Precise infusion control

By using a pump blood transfusion device combined with an electronic infusion pump, the blood transfusion speed can be accurately controlled within a wide range of 1-999ml/h, with a minimum set increment of up to 0.1ml/h, meeting various clinical needs from rapid large-scale blood transfusion to slow micro infusion. For patients with heart failure, elderly patients, or infants, precise control can effectively prevent circulatory overload.

2. Full process safety monitoring

Modern infusion pumps are equipped with multiple safety mechanisms: the air bubble detection sensor can recognize bubbles as small as 15 μ L and automatically sound an alarm; Real time monitoring of pipeline patency by pressure sensors, and immediate shutdown in case of blockage; Open door inspection to ensure that the pump door is tightly closed; The KVO (keep veins open) function automatically switches to maintain flow rate after blood transfusion is completed.

3. Reduce damage to blood components

The pump adaptation section of the pump transfusion device uses a special formula of high elasticity material, combined with the optimized extrusion curve of the infusion pump, which can significantly reduce the mechanical damage of red blood cells during infusion. Research has shown that when using pump blood transfusion equipment in a standardized manner, the increase in free hemoglobin in the blood is significantly lower than that of traditional methods.

4. Improve work efficiency

Automated infusion frees up the time of medical staff and eliminates the need for frequent manual adjustment of drip rate; The high-capacity memory function can store commonly used blood transfusion plans; The data recording function facilitates the writing of medical documents and quality traceability.

5. Standardization and compatibility

The product complies with the ISO 8536 series standard, and the Ruhr interface complies with the ISO 594/80369 standard. It can be used in conjunction with mainstream infusion pump brands at home and abroad, such as BD, B. Braun, Fresenius, Smiths Medical, etc.
