Tubing connector

Fluid delivery set

A pumping system for infusing fluids into a patient. The pumping system includes a pump and a controller constructed to control operation of the pump. The controller has a hold condition in which it deactivates the pump. The controller also has a timer subsystem having a variable duration. A magnitude control operable by a human is connected to the controller, the magnitude control being constructed to alter the variable duration of the timer subsystem of the controller. The pumping system further includes an alarm connected to the controller, the controller constructed to activate the alarm upon expiration of the variable duration of the timer subsystem.

Pump with programmable hold

An apparatus for supplying an enteral or parenteral fluid to a patient is a cooperative assembly of a rotary peristaltic pump and a fluid delivery set. The peristaltic pump has (a) a housing and (b) a peristaltic rotor projecting from the housing on a rotatable drive shaft. The housing has first and second receptacles for retaining and supporting the fluid delivery set. The fluid delivery set has (a) a drip chamber, or sight chamber, (b) a plurality of lengths or segments of flexible tubing, and (c) fluid connection elements therefor. The fluid delivery set defines a fluid pathway from a supply container of the enteral or parenteral fluid to a connector element adapted to be connected to a device for introducing the fluid into the patient. Preferably the fluid delivery set has a tension responsive pinch valve to prevent bolus feeding in the event that the fluid delivery set becomes displaced from the pump housing.

Peristaltic pump and fluid delivery set

Fluid delivery unit

A tubing connector has first and second tubular legs joined together to provide a continuous fluid pathway therethrough with the fluid pathway having a bend of about 78 to 102 degrees therein. A foreshortened retention tab extends laterally from the tubing connector at about the bend in a direction opposed to the second leg of the tubing connector. A handle extends from the tubing connector at about a right angle to both the first and second legs and the retention tab. The tubing connector may be employed as a component of a fluid delivery set used with a pump for enteral or parenteral feeding of a patient.

An apparatus and method for controlling a flow parameter of a pump. The pump includes a pumping device for pumping fluid, the pumping device having at least one flow parameter. The pump further includes a control coupled to the pumping device and a control panel having a plurality of controls operable by a human. The control is programmable by operation of the plurality of controls, thereby allowing a human to program the at least one flow parameter of said pumping device by operation of the plurality of controls. The control has a lock that can be activated by operation of at least two of the plurality of controls. Upon activation, the lock prevents the alteration of the at least one flow parameter. The method includes the step of providing the pump of the present invention, programming the at least one flow parameter by operating the plurality of controls, and activating the lock by operating at least two of the plurality of controls.

Pump with lock-out feature

A fluid delivery set has three lengths of flexible tubing. The first length of flexible tubing at one end is connectable to or integral with a supply container for enteral or parenteral fluid, and at the other end is connected to the inlet of a drip chamber. The second length of flexible tubing is connected at one end to the outlet of the drip chamber, and at the other end to the inlet of a retention/connector device that has about a 90.degree. bend therein. The third length of flexible tubing is connected at one end to outlet of the retention/connector device, and at the other end is connectable to or integral with a means for introducing an enteral or parenteral fluid into the body of a patient. Preferably, a tension responsive pinch valve is operatively associated with the second length of flexible tubing.

Rotary peristaltic pump

A stoma creator is provided comprising a flexible tube having a first opening, a tapered dilator portion, having a second opening, the diameter of the first opening being greater than the diameter of the second opening, and a connecting portion. The stoma creator has a tapered dilator having a side wall which gently tapers from approximately 5 French to 14 French. The method for using the device of this invention comprises the step of securing the stomach to the abdominal wall through the use of T-fasteners, inserting a needle percutaneously into the gastric lumen, passing a guidewire through the needle, grasping the guidewire with the endoscope and bringing it out through the mouth, threading the tapered dilator over the guidewire and passing the stoma creator down the throat into the stomach then out through the abdominal wall the stoma creator cutting of the tapered dilator and connecting portion, passing a gastrostomy tube through the flexible tube, with the gastrotomy tube having a balloon adjacent its tip, removing the flexible tube while leaving the guidewire in place, filling the balloon, and withdrawing the guidewire. A similar alternative method is also disclosed.
