摘要： A safety needle is provided. The safety needle includes a substantially hollow body and a needle assembly that includes a needle supported on a needle hub. The needle hub is movable in relation to the hollow body from an advanced position wherein a sharp tip of the needle extends from the hollow body to a retracted position wherein the sharp tip of the needle is positioned within the hollow body. The safety needle also includes a spring biased retraction mechanism that includes a constant force spring operatively connected to the needle hub. The constant force spring is a generally flat strip of prestressed material that is formed into constant coils around itself. The constant force spring is configured to bias the needle hub towards the retracted position wherein the spring provides a substantially constant force to the needle assembly while the needle assembly moves from the advanced position to the retracted position.

摘要： A relatively flexible, dual-lumen enteral feeding tube for delivery of fluid through a patient's esophagus to the patient's digestive system, the enteral feeding tube having proximal and distal ends. The tube comprises an enteral feeding lumen having a feeding lumen inlet opening adjacent the proximal end of the tube and a feeding lumen outlet opening adjacent the distal end of the tube. Additionally, a relatively small stylet lumen is provided separate from said enteral feeding lumen, the stylet lumen having a stylet lumen inlet opening adjacent the proximal end of the tube and being longitudinally co-extensive with a substantial length of the enteral feeding lumen. A relatively stiff stylet having a tapered annealed distal portion is removably positioned in the stylet lumen and extends from the stylet inlet lumen opening to adjacent to the feeding lumen outlet opening. A Y-site adaptor is fixed on the proximal end of the tube and the stylet is shorter in length than the distance from either of the Y-site openings to the tube outlet opening. To facilitate insertion or removal of the stylet, which is constructed of metal, into or from the stylet lumen, a portion of the stylet is provided with a first coating of polytetrafluorethylene having a second coating of silicone over the first coating.

摘要： A modular drainage apparatus has a plurality of preformed plastic bodies supported by a header. One of the bodies includes a collection chamber connected to the pleural cavity of a patient and connected to a first passage formed in the header. A second body includes a U-shaped liquid seal chamber having one end connected to the first passage and its other end connected to a second passage formed in the header. The second passage is connected to a vacuum pump, which creates a suction within the collection chamber through the liquid seal chamber. A third body includes a U-shaped chamber to regulate the negative pressure produced by the vacuum pump to a desired negative pressure. The second body also includes a second U-shaped chamber having one end connected to the atmosphere and its other end connected to the liquid seal chamber adjacent its connection to the first passage. By filling each leg of the second U-shaped chamber of the second body to a selected level with a liquid, the negative pressure in the collection chamber is maintained at a selected maximum above the pressure maintained in the collection chamber by the vacuum pump and regulated by the U-shaped chamber of the third body.

摘要： An access port for the introduction of a needle cannula tip into an IV tube set includes a rigid tubular housing and a resilient member disposed adjacent an inlet of the housing. The resilient member includes an axial perforation extending through the resilient member, and is normally closed by the resilient character of the resilient member. A depression is defined in a proximal face of the resilient member, and includes sidewalls extending between the proximal face and the axial perforation to guide the tip of the cannulated needle toward the perforation as the cannulated needle is introduced into the access port.

摘要： Featured is a vascular access device such as an IV catheter device including a housing, a tubular member, a seal member, a compression member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal housings. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also forms a septum, which is compressed by the compression member to prevent seepage upon removal of a stylet.

摘要： A gross filter in a drainage device for filtering fluids drained from the pleural cavity of a patient comprising a filter body having a first side panel, second side panel, back panel and bottom panel that assemble to form a generally box-shape filter with open front and top portions. The gross filter is located in the first of two subchambers that comprise the collection chamber. The filter body further comprises a filter screen sized for filtering gross particulates, such as blood clots, that may become entrained in fluid drained from a patient. The gross body is configured so as to permit the further filtering of fluids when blood clots have formed and blocked the filter screen of the filter's bottom panel from fluid flow therethrough, thereby allowing uninterrupted filtering of blood into the collection chamber through the first and second side panels instead. To further facilitate the filtering of blood through the filter body when a blocked state exists at the bottom panel portion thereof, the first and second side panels are angled toward each other at their bottom ends and gradually spaced apart from the collection chamber walls in order to permit unimpeded filtering of fluid through the side panels. The open front portion of the gross filter permits clear viewing by medical personnel of the amount of blood clots being retained inside the filter body so that measuring indicia may be provided on the drainage unit's front panel as an indication of the amount and rate of blood clot retention inside the filter. An overflow filter portion is also provided at the top portion of one of the side panels for filtering fluid when the rest of the filter body is clogged and blocked by blood clots or when the first subchamber is filled to capacity.

摘要： A CDU hanger mount assembly and hanger is provided. The mount assembly and hanger allows the CDU to be supported by an object for supporting the CDU while the connecting point between the hanger mount and the pivot end of the hanger may be selectively moved from a point midway between the front and back of the CDU top toward the back of the CDU. This allows the CDU to be less displaced from the vertical upon displacing contact with an object such as a bedframe piece. The hanger and hanger mount assembly allows the alignment of the indicia on the CDU with the top surface of the material collected in the CDU to be a more accurate representation of the actual volume of material collected in the CDU. The mount assembly and hanger may also be used with medical devices other than CDUs.

摘要： A syringe assembly including a plunger rod and a plunger tip which are designed to provide a low frictional resistance against the interior surface of the syringe barrel while the plunger rod is at rest but which will increase the sealing pressure between the plunger tip and the interior surface of the syringe barrel in proportion to the amount of force applied to the plunger rod. Additionally, the plunger rod may be moved in the syringe barrel in a laterally offset manner with respect to the longitudinal axis of the syringe barrel without significantly affecting the seal between the plunger tip and the syringe barrel.
