Yes
The device is described as an infusion pump intended for controlled delivery of parenteral fluids and Patient Controlled Analgesia (PCA), which are therapeutic administrations.
No
Explanation: The device is described as an infusion pump for controlled delivery of parenteral fluids and various infusion therapies (e.g., PCA, TPN), not for diagnosing conditions.
No
The device description clearly describes a "small, battery-operated peristaltic infusion pump" which is a hardware device. While it utilizes software for programming and control, the primary medical device is the physical pump itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "controlled delivery of parenteral fluids," which means delivering substances directly into the body (e.g., through veins). This is a therapeutic function, not a diagnostic one.
- Device Description: The description focuses on the pump's ability to deliver fluids in various ways (continuous, variable, PCA, TPN, intermittent). It's about administering treatment, not analyzing samples from the body to diagnose a condition.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, urine, tissue, etc.) to provide information about a patient's health status.
IVD devices are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device operates in vivo (within the body) to deliver substances.

Device Description
The Disetronic Multifuse pump is a small, battery-operated peristaltic infusion pump that is suited for ambulatory hospital and home use. The pump is extremely versatile. It has been designed to allow the health provider program the pump to provide one of several types of infusion therapies. The pump can be configured as a continuous rate infusion pump with demand bolus capability, a variable rate infusion pump with demand bolus capability, a Patient Controlled Analgesia (PCA) pump, a Total Parenteral Nutrition (TPN) pump or an intermittent infusion pump. The health provider can further customize the pump for a specific patient by allowing or excluding optional programming steps, limiting allowable ranges, adjusting the rate at which boluses are infused and adjusting alarm and display features. These control functions can only be performed by using the Multifuse Computer Software. This proprietary control software runs on IBM compatible personal computers in the Windows environment and communicates with the pump through an optical interface. The pump can be re-programmed as required for different patients. This versatility enables the health care provider minimize the different types of pumps and still provide for almost all infusion therapies.
The base housing holds the pumping mechanism, electronics, and batteries. This housing is sealed against water to help prevent internal damage. The front panel on this housing has a dotmatrix LCD display, four input buttons, and two LED status indicator lights. Specific infusion parameters can be programmed using the input buttons on the front panel. There is also an optical interface on the panel for two way communication with a computer or modem. The Multifuse pump uses four AA-size main batteries. It also accepts rechargeable batteries or can be powered with an available AC adapter. The pump has a separate back-up battery to maintain the pump's memory while the main batteries are being changed or if they become depleted. The pump infuses fluid by means of a sterile disposable tubing cassette that snaps into the pump. The cassette has a short section of pumping tube which is squeezed by the pump mechanism to cause the pumping action. The cassettes are available with several different diameters of pumping tubing which offer different flow rate ranges. The cassette has an optical code corresponding to the tube's diameter which is read by the pump's electronics to safely and automatically adjust the flow rate range. The cassette has an air detection chamber, a pressure detection chamber, and an antifreeflow valve. The air and pressure detection chambers work together with detectors in the pump housing. The cassettes are available in a number of different configurations including different lengths, connectors, filters, injection ports, etc. A cover for the cassette snaps in place to protect the cassette and sensors during use. This cover also provides a back-up plate against which the pumping mechanism squeezes the flexible tubing. The tubing cassette connects to a bag-type reservoir which holds the liquid medication. This reservoir may be any suitable standard W bag or Disetronic Multifuse Reservoirs. The Multifuse reservoirs are made to fit into one of the pump's reservoir holders. These holders slide into a dovetail on the housing and can be changed to the appropriate size. The reservoir holders help protect the reservoir, improve the portability, and may also be locked for security. Other accessories available for use with the Multifuse include an AC adapter, a belt carrying clip, various carrying pouches, a remote bolus button, and a modem.
The basic pumping method used in the Disetronic Multifuse Pump is an elastic tube acted upon by three squeezing fingers. The first and third of these fingers, together with the tube, act as valves. The middle finger, together with the tube, is a volume displacement chamber. The tube is positioned between the fingers and a platen. This platen acts as a back-up plate against which the tubing is squeezed. The fingers are moved by a camshaft and motor in a specific sequence so that the tube passively fills from the upstream side and is actively emptied into the downstream side. This is done repetitively to effect an accurate, relatively constant flow. The Disetronic Multifuse Pump delivers a small, accurate volume each cycle of the pumping mechanism. Different flow rate ranges are obtained with different diameters of elastic tubing. The low range cassette dispenses 100 µ-liters and the high range cassette 250 µ-liters per cycle, respectively. Each complete output cycle is further resolved into approximately 25% segments by the position sensing electronics. By doing so, the size of, and thus time between, incremental infusion volumes is one-fourth as small as with complete cycles. Thus, the actual incremental volumes are 25 u-liters and 62.5 u-liters for the low and high range cassettes, respectively. This is particularly valuable at low flow rates and helps to improve the continuity of flow. Although the 25% segments are approximated, the overall flow accuracy is not affected due to the accuracy of each complete cycle. For low flow rates, the pump delivers the one-fourth cycle volume each incremental output and calculates the time, in multiples of one minute, necessary to achieve the correct flow rate. For higher flow rates, the pump delivers an incremental volume every one minute. The volume of these increments is calculated to achieve the correct flow rate. Bolus volumes are calculated and delivered directly based on the necessary number of cycles or parts of cycles. Therefore, the bolus volume accuracy is independent of its flow rate.
The Disetronic Multifuse Pump has five different basic modes of infusion profiles, or types that can be selected. These are called the C-type (Continuous), V-type (Variable), PCA-type (Patient Controlled Analgesia), INT-type (Intermittent), and TPN-type (Total Parenteral Nutrition), Each of these profiles can modified by adding or eliminating certain characteristics to meet the specific needs of the patient. The basic parameters of these types are:
Continuous Infusion - constant rate output
Infusion Rate - rate at which drug is infused
Infusion Volume - volume to be infused
Infusion Time - time duration of therapy
KVO Rate - rate of infusion to maintain an open vein between infusions or boluses
Start Delay - time delay before therapy begins
Cycle Time - time for each therapy for repetitive therapies
Demand Bolus - amount of a patient demand bolus
Physician Bolus - amount of a bolus programmed by the physician to be automatically delivered
