Description
Technical Parameters
A hand crank peristaltic pump is a special type of peristaltic pump that is powered by manual (i.e., hand crank) actuation, rather than by electric or other automatic means.
The working principle of the peristaltic pump is based on the peristaltic effect, that is, through a series of sequential squeeze and release action to drive the fluid moving in the pipeline. Hand-operated peristaltic pumps built-in soft, made of elastic materials, when manually rotating the crank, it will drive the internal roller or compression mechanism sequentially squeeze the pipeline, thus driving the fluid inside the pipeline to flow forward. This squeezing and releasing action is continuous and cyclical, allowing for a constant and steady flow of fluid.

in emergency medical application
In a polar expedition organized by a professional expedition team, the expedition team encountered a sudden snowstorm, resulting in a team member accidentally fell and was seriously injured. Due to the bad weather, it was impossible to carry out air rescue immediately, the expedition team had to rely on their own medical equipment and medicines to carry out emergency treatment for the injured player. At this point, the hand-operated peristaltic pumps carried by the team played a key role in the precise distribution of medicines.
► Emergency Medical Situation
The injured team member's injuries were serious and required immediate treatment to stop bleeding and fight infection. The expedition's medical kits were stocked with the necessary medicines, including hemostatic agents and antibiotic solutions, but these needed to be delivered in precise doses. In extremely cold conditions, where conventional syringes or infusion equipment may fail due to hypothermia, hand-operated peristaltic pumps are ideal due to their stability and precision.
Steps for hand-operated peristaltic pumps
Preparing medicines and hoses:
The expedition's medical staff quickly removes the hemostatic and antibiotic solutions from the medical kit, as well as the hoses adapted for the hand-cranked peristaltic pump.
Attach one end of the hose to the container of medication and the other end to the injured team member's infusion set.
Set the parameters of the pump:
Based on the instructions for the medication and the weight and age of the injured team member, the medical staff calculates the dose of medication needed.
By adjusting the roller spacing and cranking speed of the hand-operated peristaltic pump, it ensures that the medication is delivered at a precise flow rate.
Starting to deliver the medication:
The medical staff begins to crank the hand-crank peristaltic pump, and as the rollers squeeze and release, the medication is steadily delivered into the injured team member's body.
During the delivery process, the medical staff closely monitors the injured team member's response and vital signs to ensure that the medication is delivered safely and effectively.
Monitoring and adjustment:
According to the injured team member's reaction and changes in vital signs, the medical staff adjusts the delivery speed and dosage of the drug at the right time.
By observing the flow rate of the hose and the remaining amount of medication, it was ensured that the delivery of medication was completed within the scheduled time.
► Results and Summary
In the emergency medical treatment of the expedition, the hand-operated peristaltic pump played an important role with its precise, stable and easy-to-operate characteristics. It not only ensured the precise delivery of medicines, but also improved the efficiency and safety of medical treatment. Through this experience, the expedition team deeply appreciated the value of hand-operated peristaltic pumps in the wild adventure and emergency medical treatment, and plans to continue to carry this equipment in future adventures in case of emergency.
Hand-operated Peristaltic Pumps in Wilderness Expeditions
In a professional expedition organized by the expedition team in the wild adventure activities, the expedition team plans to travel through a sparsely populated primitive forest, a week-long investigation and exploration. The forest is located in a remote area, where water is scarce and unstable, while the expedition members may face various medical emergencies. In order to ensure the smooth running of the expedition, the team decided to carry a hand-operated peristaltic pump as one of the key equipment.
Prior to departure, the team inspected and tested the hand-operated peristaltic pumps to ensure that they performed well and were easy to operate. They prepared enough hoses and adapters to allow flexible connections between different water sources and containers. In addition, the expedition team also prepared a sufficient stock of drinking water and necessary medicines in case of emergency.
On the third day of the expedition, the expedition team found a clear stream, but the stream is located under steep rocks, making it difficult to get water directly. At this point, the hand-operated peristaltic pump played a key role. The explorers connected one end of the pump to the creek and the other end to a large water bag, and by rotating the hand crank, they successfully extracted water from the creek into the water bag. This not only solved the drinking water problem of the expedition team, but also provided them with enough clean water for cooking and washing.
On the fifth day of the expedition, one of the expedition members was accidentally injured and needed urgent treatment. As the medicines carried by the team were in liquid form and needed to be dispensed accurately, the hand-operated peristaltic pump came in handy once again. The expedition team connected one end of the pump to the medicine container and the other end to a precise dispenser, and by adjusting the rotational speed of the hand crank, successfully delivered the required dose of medicine to the injured team member's wound. This not only improved the utilization of the medication but also ensured precise dispensing of the medication.
Throughout the expedition, the hand-cranked peristaltic pump became one of the indispensable equipment for the expedition team. It not only solved the expedition's drinking water problem, but also provided them with the ability to deliver medicines and other necessary fluids in emergency situations. The expedition members have expressed that the hand-operated peristaltic pump is easy to operate and reliable, which is one of the important guarantees for them to be able to successfully complete the expedition.
Through this expedition, the expedition team deeply appreciated the hand-operated peristaltic pump in the field operations in the important role. They plan to continue to carry this equipment in future expeditions and explore more possible application scenarios to further improve the safety and efficiency of the expedition.
