Intended Use
The enteral feeding pump accurately controls the flow of liquid feeding solution to patients who are unable or unwilling to consume adequate nutrients. Liquid feedings may consist of commercially prepared formulas or blenderized foods and are most often delivered by means of nasogastric, nasoduodenal of nasojenjunal feeding tubes. In some cases a surgically placed esophagostomy, gastrostomy or enterostomy tube may be used. The pump is not intended for use with blood or blood products. The pump is not for intravenous delivery.
Device Description
The SENTINEL / LH2001 is a peristaltic pump intended for controlled delivery of liquid nutrients. The pump requires cleared disposable delivery tube sets approved by ENTRACON CORPORATION. The pump is used to feed hospital or long term care patients. The microprocessor controlled pump operates while normally connected to a 120 VAC outlet. In the event of AC power loss, or when moving patients, the pump operates on an internal backup battery. The battery is always being charged by during AC power use. With a fully charged battery, the pump can operate for 12 hours at a set delivery rate of 125 ml/hr. The pumping mechanism is a rotor, driven by a stepper motor. The stepper motor runs at a constant speed with delivery rate dependent on on/off timing. The pump includes an integral pole clamp for securing it, typically to an IV pole. Visual and auditory alarms warn of flow-related problem conditions; either occluded flow or excessive flow. Flow detection is accomplished by optically sensing falling drops of nutrient in the pump-mounted drip chamber. Additionally, other warning actions occur when liguid nutrient container is empty, when the pump has completed delivery of a preprogrammed dose, when the pump has been idle for more than 2½ minutes, or when, during battery operation, the battery requires recharging.
More Information

No
The device description details a microprocessor-controlled peristaltic pump with a stepper motor and optical flow sensing. There is no mention of AI, ML, or any learning or adaptive capabilities. The control logic appears to be based on pre-programmed parameters and sensor inputs.

No
This device is an enteral feeding pump that delivers liquid nutrients, which is a supportive function rather than directly treating a medical condition or disease.

No
The device is an enteral feeding pump designed to deliver liquid feeding solutions to patients; its function is therapeutic, not diagnostic.

No

The device description clearly outlines hardware components such as a peristaltic pump mechanism, stepper motor, internal backup battery, pole clamp, and optical sensors for flow detection. It is a physical device with embedded software controlling its operation, not a standalone software application.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device "accurately controls the flow of liquid feeding solution to patients". This is a therapeutic function, delivering nutrients directly to the patient's body.
  • Device Description: The description details a "peristaltic pump intended for controlled delivery of liquid nutrients". This further reinforces its role in administering substances to the patient.
  • Lack of Diagnostic Function: There is no mention of the device being used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. IVDs are used to test things like blood, urine, tissue, etc., to help diagnose or monitor a medical condition.

This device is an enteral feeding pump, which is a medical device used for delivering nutrition directly into the gastrointestinal tract. This is a form of medical treatment, not a diagnostic test.

(a)
Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)
