Description
Technical Parameters
Sanitary peristaltic pump is a device designed for situations requiring high hygiene standards. It is a pumping device with constant flow pump and hose pump characteristics, which is characterized by the ability to isolate the fluid in the pump tube, enabling rapid tube replacement, allowing the fluid to reverse and dry operation. Since the fluid only comes into contact with the hose and is not contaminated by moving parts, it is ideal for use where high hygiene standards are required.
The working principle of this peristaltic pump is based on the cycle of "extrusion - rebound". The motor drives the rotor to rotate, and the rollers successively press the hose, forming a locally closed liquid cavity inside the hose. When the roller moves forward, the liquid in the liquid chamber is pushed forward, achieving the transportation of the liquid. When the hose bounces back, the negative pressure generated will continuously draw in new liquid, eliminating the risk of liquid backflow. This working mode ensures that the liquid only comes into contact with the inner wall of the hose, avoiding contact with other components, thereby guaranteeing the purity and pollution-free nature of the liquid.
Specifications
Regional anesthesia
Regional anesthesia, also known as local anesthesia, refers to the injection of anesthetic drugs into an area of the body, so that the sensory nerve conduction in the area is blocked, so as to achieve the effect of anesthesia. Regional anesthesia has the advantages of limited scope of anesthesia, little impact on the overall patient, and quick recovery after surgery. In the process of regional anesthesia, it is important to precisely control the delivery speed and dosage of anesthetic drugs to ensure the anesthetic effect and patient safety.
advantages
Precise control
The peristaltic pump can accurately control the delivery speed and dosage of anesthetic drugs through the precise extrusion and release of the hose by the roller. This precise control helps to ensure the uniform distribution of the anesthetic drug within the target area, improving the anesthetic effect.
Stability
The peristaltic pump can maintain a stable conveying speed and pressure during the conveying process, avoiding the instability of the anesthetic effect caused by fluctuations in drug delivery. This is important for maintaining the comfort and safety of patients during surgery.
Aseptic operation
Sanitary peristaltic pumps are designed to meet the sterile requirements of medical devices, and their hoses and pump heads are usually made of materials that are easy to clean and sterilize. This ensures that the anesthetic is not contaminated during delivery, reducing the risk of infection.
Easy to maintain
The structure of the peristaltic pump is relatively simple and easy to disassemble and clean. This reduces maintenance costs and also reduces the risk of surgical disruption due to equipment failure.
Specific applications
Nerve block anesthesia
In nerve block anesthesia, peristaltic pumps can be used to deliver local anesthetic drugs to the nerve stem or near the nerve plexus to block nerve conduction. By precisely controlling the delivery speed and dose of the drug, the effective concentration of the anesthetic drug in the target area can be ensured and the success rate of anesthesia can be improved.
Intraspinal anesthesia
Intraspinal anesthesia is the injection of anesthetic drugs into the spinal canal to block the conduction of the spinal nerves. Peristaltic pump can be used to transport narcotic drugs into the spinal canal, through the precise control of drug delivery speed and dose, can ensure the uniform distribution of narcotic drugs in the spinal canal, improve the anesthetic effect.
Surface anesthesia
Topical anesthesia is the application or spraying of narcotic drugs on the mucous membrane or skin surface to block the conduction of the superficial nerve. Although surface anesthesia usually does not require precise control of the delivery speed and dosage of the drug, peristaltic pumps can still be used to deliver anesthetic drugs to ensure an even distribution of the drug and reduce waste.
Precautions for use
Select the right pump type and hose
According to the characteristics of anesthetic drugs and delivery needs, choose the appropriate peristaltic pump type and hose material. Ensure that pump type and hose can meet anesthetic delivery speed, pressure and sterility requirements.

Optimize flow rate and pressure
Adjusting the design of the chromatographic column to optimize the flow rate and pressure can be done by:
- Increase column diameter
At the same pressure, the thicker column can provide a larger channel area, which reduces the flow resistance and increases the flow rate.
It should be noted that increasing the diameter will cause the elution volume to increase and the sample dilution to increase, which may affect the separation degree. Therefore, the appropriate diameter should be selected according to the specific experimental requirements.
- Ratio of column diameter to column height
When designing chromatographic columns, the proper ratio of column diameter to column height should be maintained to ensure the uniform distribution of fluid in the column and good separation effect.
- Effects of column bed height
The higher the height of the column bed, the more resistance the fluid needs to overcome in the column, resulting in an increase in pressure.
On the other hand, the column bed height also affects the separation degree, and the separation degree is related to the square root of the column height. Therefore, it is necessary to find a balance between pressure and separation.
- Optimized column bed height
According to the experimental requirements and column performance, select the appropriate column bed height. On the premise of ensuring the separation effect, reduce the height of the column bed as much as possible to reduce the pressure.
- Packing type
Different fillers have different pore size, specific surface area and adsorption properties, which will affect the flow and pressure range of the fluid in the chromatographic column.
Select the right filler type to meet the experimental requirements and optimize the flow rate and pressure.
- Packing particle size and uniformity
The particle size and uniformity of the fillers have a great influence on the smoothness of fluid flow in the chromatographic column. Packing with moderate particle size and good uniformity can reduce the resistance of fluid passing and increase the flow rate.
- Reduction of dead volume
The dead volume under the filter plate of the chromatographic column should be as small as possible to avoid remixing between the separated components, affecting the elution peak shape and resolution.
- Material and sealing of the column
Select the appropriate column material, such as glass or plexiglass, to ensure its pressure resistance and corrosion resistance.
Ensure that the column is tightly connected to avoid leakage to maintain a stable flow rate and pressure.
In summary, the flow rate and pressure of sanitary peristaltic pump can be optimized by adjusting the design parameters such as column diameter, column bed height, packing type and particle size, and the separation efficiency of chromatographic column and the accuracy of experimental results can be improved. In actual operation, it is necessary to comprehensively consider and adjust according to specific experimental requirements and column performance.
