  • Patent number: 11446110
    Abstract: Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

  • Patent number: 11426519
    Abstract: An autoinjector includes: an insertion spring between a housing and plunger assembly; a syringe driver; a second release mechanism releasing the plunger assembly from the housing, causing the insertion spring to move the plunger assembly through the housing with a syringe driver; a stop limiting movement of the syringe driver in the housing; and a third release mechanism releasing the plunger assembly from the syringe driver upon engagement with the stop, allowing the plunger assembly to continue through the housing. The first release mechanism releases the plunger from the delivery spring housing upon contact between the plunger assembly and a bung, causing the delivery spring to separate the delivery spring housing and the plunger, applying a delivery force to a bung. A latch mechanism latches the delivery spring housing at a forward position, preventing rearward movement of the delivery spring housing following release of the plunger.

  • Patent number: 11337894
    Abstract: Improved apparatus for use with animal medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel (noting that the syringe adapter will be replaced with a needle prior to injecting the medication).

  • Patent number: 11291801
    Abstract: A patient access site securement system includes a housing with an inlet, an outlet and an internal fluid path between the inlet and the outlet. The housing also has a connecting portion that connects to a catheter and/or a fluid line attached to the catheter. A contact surface is located on an underside of the housing and positions the patient access site securement system on the patient. A first reservoir with an interior holds a liquid and transitions from a first state to a second state. The interior is in fluid communication with the inlet when the reservoir is in the second state to allow the liquid to flow from the inlet, through the internal fluid path and exit the outlet. The liquid interacts with the contact surface and/or the patient to alter a level of securement between the catheter and the patient.
