摘要： Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. 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 is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.

摘要： A safety shield apparatus including a safety shield and mounting structure for mounting the safety shield to a medical needle. The safety shield includes a distal segment, a proximal segment and a retention member. The distal segment is pivotally secured to the proximal segment and the proximal segment is pivotally secured to the retention member. The retention member includes an opening for receiving a nose of a medical needle device, e.g., a blood collection device. In one embodiment, a retaining collar is provided which is dimensioned to be press-fit about the nose of the medical needle device to secure the safety shield to the medical needle device. Alternatively, mounting structure is formed directly on the retention member to secure the safety shield to the medical needle device.

摘要： A fluid collection apparatus is provided that includes a housing configured for receipt of fluid and/or tissue for collecting fluid therefrom. A holder is configured with the housing to receive an evacuated tube. The holder can include a needle hub supporting a needle cannula in fluid communication with a port extending into a fluid well of the housing. A sloped bottom surface of the housing directs fluid to the fluid well. A sidewall extension or support component extends downward beyond the sloped bottom surface to allow the housing to be stood upright on a flat surface. In certain embodiments, the apparatus includes a tubular cavity to provide a recessed location of the needle cannula for preventing accidental needle injuries. An optional cap provides further shielding from needle cannula and safely maintains fluid in housing after use.

摘要： A needle cannula apparatus is provided which includes a needle hub that is mountable to an instrument and has a cantilevered portion extending therefrom. The cantilevered portion has a button member and a hub stop disposed at a distal end thereof. The needle hub defines at least one tab slot having a tab slot end. A shield is movably disposed about the needle hub and defines a shield slot configured for relative slidable movement of the button member therein. The shield slot includes a proximal enlarged slot section configured to engage the hub stop such that proximal movement of the shield is prevented. The shield further includes at least one tab stop that is configured for movement within the at least one tab slot of the needle hub and engagement with the tab slot end such that distal movement of the shield is prevented. The needle cannula hub may include at least one hub slot and the shield includes at least one shield rail. The at least one shield rail sidably engages the at least one hub slot facilitating axial movement of the shield relative to the needle hub. The shield slot may further define a transport enlarged slot section disposed between a distal portion of the shield slot and the proximal enlarged slot section. A method for transport and use of the needle cannula apparatus is disclosed.

摘要： A valve for relieving an excess negative pressure condition inside a medical device comprising a diaphragm with an inner periphery and an outer periphery and an actuator having a piston extending axially therefrom which is inserted through the inner periphery of the diaphragm. The piston comprises a plurality of legs that form a void therebetween at the free end thereof. The outer periphery of the diaphragm is sandwiched between the upper and lower housings so as to create a hermetic seal that separates the valve into a venting side and a suction side. To relieve an excess negative pressure condition the diaphragm is operable in one of two positions. In the first position, a biasing members forces the inner periphery of the diaphragm in sealing engagement around the circumference of the piston so that a hermetic seal is maintained between the suction side and the venting side. When negative pressure inside the medical device begins to rise, the inner periphery of the diaphragm moves in sealing engagement along the piston so that a constant sealing force is applied around the circumference of the piston until it reaches the plurality of legs at the free end thereof. As the inner periphery moves over the plurality of legs, the void establishes communication with both the suction side and the venting side, thereby permitting ambient air to vent into the suction side and lower the negative pressure therein.
摘要翻译：一种用于缓解医疗装置内的过量的负压状态的阀，包括具有内周和外周的隔膜和具有从其延伸的活塞的致动器，该活塞通过隔膜的内周插入。活塞包括在其自由端处在其间形成空隙的多个腿。隔膜的外周被夹在上壳体和下壳体之间，以便产生将阀门分离成通气侧和吸入侧的气密密封。为了减轻过量的负压条件，隔膜可在两个位置之一中操作。在第一位置，偏置构件迫使隔膜的内周缘围绕活塞的周边密封接合，从而在吸入侧和通气侧之间保持气密密封。当医疗装置内部的负压开始上升时，隔膜的内周沿着活塞密封接合，从而在活塞周围施加恒定的密封力，直到其自由端到达多个腿部。当内周在多个腿部移动时，空隙与吸气侧和通气侧两者形成连通，从而允许环境空气排出到吸入侧并降低其中的负压。

摘要： A footstand for stabilizing a body of a medical device against being overturned. The body may especially be a chest drainage unit (CDU) designed and configured to receive and collect fluids from a medical patient. The invention comprises at least one stand coupled to the body and adapted for deployment to a position for stabilizing the body against upset. The CDU body is a generally upstanding rectangular box having a pair of depending feet, one foot on each side of the body. The stand, is rotatably connected to the bottom of the CDU body and is provided with a height adjustment feature which allows the stand to be rotated between a first undeployed position wherein the stand covers or encloses the depending fee of the CDU body while providing a relatively smooth and continuous bottom stand surface to a second deployed position wherein the bottom stand surface is at the same height or in the same horizontal plane as the bottom of the depending feet of the CDU body to provide a solid and secure footstand for the CDU body. It is desirable to provide a footstand for a CDU which provides a smooth contoured surface for the CDU bottom when the footstand is in its first undeployed position so that the CDU bottom will not puncture the sterile package during transportation of the CDU to an end user or during storage of the CDU prior to use or during disposal of the CDU after use in a hazardous disposal bag.

摘要： A syringe needle thimble cap and its method of use is shown such that the thimble cap has a porous plastic, hydrophilic core captured within a cylindrical cap member for use with an arterial blood gas syringe barrel and needle assembly. The syringe needle thimble cap has a generally thimble-shaped cap with a proximal opening. The porous plastic core material is positioned within the thimble cap distally to the proximal opening, and the core material is held in place by an inwardly extending ring to prevent its removal. An open or hollow space is created distally to the porous material which is otherwise bounded by the interior surfaces of the thimble cap.
