Since the introduction of progressive cavity (PC) pumps (see Figure 1) many years ago, stator maintenance has been a concern of plant operators and maintenance personnel. ... but this often requires chemical testing of elastomers prior to the pump's purchase. Consider cost, wear resistance, chemical resistance and …
A sheet of VHB-4910 tape is rolled into the pump module with the seam self-bonded. The initial length, radius, and thickness of the pump module are L 0 = 40 mm, R 0 = 20 mm, and H 0 = 1 mm. The pump module experiences a prestretch of λ pre = 2 and is enforced at two ends by two rigid tubes. The working length l is defined as the length of …
In a bid to support the switchover to electric vehicles, Hutchinson has pioneered a new elastomer compound for Volkswagen that is capable of withstanding the operating constraints of R744, a refrigerant that holds plenty of promise for the thermal management of electric and hybrid vehicles, but which requires all the circuit …
An elastomeric pump, also known as a balloon pump or ball pump, is a medical device used for infusing medication. Depending on the therapy needed, these medications …
Elastomeric pumps offer a safe alternative to electronic pump systems for various therapeutic areas and applications. They are intended for single use and, in contrast to electric infusion pumps, work without external energy …
Using voltage-controlled elastomer actuation 35, we also open up a path towards a plug-in-ready all-soft heat pump. Fig. 1: Illustration of the geCC effect in elastomers, heat pump design ...
Because of its long infusion time over 46–48 hours, 5-fluorouracil (5-FU) is usually administered with an ambulatory infusion pump in the outpatient setting. However, two …
The active-cooling elastomer concept, originating from vascular thermoregulation for soft biological tissue, is expected to develop an effective heat dissipation method for human skin, flexible ...
The stretchable fiber pump developed in this study (Fig. 1a) is highly flexible owing to its main material, silicone elastomer. As depicted in Fig. 1b, our pumps consist of a pair of heroical ...
How Elastomeric Pumps Work. Elastomeric pumps use pressure to infuse medication. This pressure is created by an elastomeric layer which is molded into the inside of the pump. When the elastomeric pump gets filled, the elastomeric layer becomes stretched. The elastic constriction then drives the liquid that is present through the tubing.
The progressive cavity pump is an excellent choice as the fluid viscosity increases beyond the efficient range of centrifugal pumps. ... (usually made of an elastomer) that has a double helix cavity. The concept seems complex, but once you visualize how it works the simplicity and the beauty of the design is clear.
Polymeric elastomers are extensively employed to fabricate implantable medical devices. However, implantation of the elastomers can induce a strong immune rejection known as the foreign body ...
To describe the avoided costs and to analyze the effectiveness of intravenous antibiotic treatment in continuous perfusion in patients at Hospital at Home …
The energy generated during shock loads is essentially absorbed by the elastomer in a twisting action. One of the biggest benefits of tire-type and sleeve-type elastomeric shear couplings is that they are designed to fail under excessive shock loads and disconnect the pump from the motor to protect the pump in the event of a lockup or …

Elastomeric infusion pumps are designed for continuous drug delivery, on-demand delivery or a combination of continuous and on-demand drug delivery (patient-controlled analgesia, PCA).. Elastomeric pumps offer a safe alternative to electronic pump systems for various therapeutic areas and applications. They are intended for single use and, in contrast to …
Air operated diaphragm pumps are used in many applications requiring abrasive and chemical resistance. When both are needed, an elastomer with some chemical resistance, or a polytetrafluoroethylene (PTFE) diaphragm with an elastomer backing, is typically used.
14 rowsEasypump ® ST/LT elastomeric infusion pumps are designed to give clinicians and nurses the option to deliver pre-determined amounts of medication to the patient in a continuous and accurate manner, either in …
Abstract: Dielectrophoretic elastomers actuators are a new class of actuator capable of achieving out-of-plane deformation by the stimulation of external electric fields, providing an alternative approach for soft electric actuators. Pneumatic pumps based on dielectrophoretic elastomer actuators have been presented with a simple structure, …
This information describes your elastomeric pump (SMARTeZ ® pump or Easypump ®) and explains what to do during your continuous infusion with your pump. …
SMARTeZ® disposable elastomeric pumps are intended for intermittent and continuous antibiotic infusion, chemotherapy, pain management and general infusion therapies. …
SMARTeZ® Elastomeric Infusion Pumps. The SMARTeZ® Pump allows medication to be delivered to the patient by positive pressure applied by the elastomeric membrane. The flow rate is determined by the combination …
