An auto-occlusion safety device is provided for use in preventing rupture of infusion components during rapid infusion procedures. An occlusion valve is disclosed having a threshold pressure that is less than a rupture tolerance of the infusion system components. As the fluid pressure of the infusion system increases beyond the threshold pressure of the occlusion valve, the occlusion valve is automatically activated thereby occluding fluid flow upstream from a vulnerable infusion component. An accumulator is further disclosed for use in combination with the safety device to compensate for time delays in full activation of the occlusion valve.

The rapid infusion attachment may comprise a spring that, when compressed, provides a spring force to the plunger of the syringe. The device comprising the syringe and the rapid infusion attachment may be shipped and stored such that the syringe is pre-filled and the spring is pre-loaded, or compressed. The device may also be shipped and stored with the spring uncompressed, and a clinician or other user may compress the spring prior to attaching the device to an IV set or other fluid pathway. The device may further comprise a mechanism that allow the clinician to control the fluid flow. The device may also further comprise a locking mechanism that can be released when the fluid in the syringe is to be injected.

An apparatus and method for direct drug infusion from a vial to a patient are provided. A movable hanger label is provided to adhere to and support the vial to facilitate direct infusion of a drug, such as one or more pharmaceuticals, biopharmaceuticals, and / or biologics, from the vial to the patient. Additionally, a process is provided in which the drug, contained in the vial with the movable hanger label, may be directly infused through a primed infusion line with a rapid infusion rate. A saline flush is incorporated at the end of the administration to flush the infusion line, resulting in a reduced amount of the drug remaining in the line.

An apparatus and method are provided for direct infusion of a medication from a vial to a patient. Also provided is a mobile hanger label to be adhered to and supported by the vial to facilitate direct infusion of a medication, such as one or more pharmaceuticals, biotechnology drugs, and / or biological agents, from the vial to the patient. Further, a method is provided in which the medication contained in the vial with the mobile hanger label can be directly infused through a primed infusion line at a rapid infusion rate. At the end of administration, a saline flush is added to flush the infusion line, thereby reducing the amount of medication remaining in the line.

A first operation opening and a second operation opening are formed in the top face and the side face of an infusion bin respectively, a baffle is vertically arranged in the second operation opening, rotating shafts are arranged on the inner side of the baffle at intervals, and clamping plates are rotationally arranged on the rotating shafts; the movement module can drive the clamping plate to rotate around the rotating shaft and close and clamp towards the baffle, a positioning hole is formed in the bottom of the baffle, the monitoring module is used for monitoring the flow of the infusion tube, and the tail end of the infusion tube is communicated with a puncture needle of the bone marrow puncture infusion apparatus. The bone marrow puncture infusion apparatus quickly establishes an infusion passage and is communicated with a puncture needle, an infusion bag is placed on a clamping plate, an infusion bag connector extends out of a positioning hole, an infusion tube is communicated with the infusion bag connector, a movement module drives the clamping plate to extrude the infusion bag, liquid medicine flows out of the infusion bag connector in a pressurized mode, and a monitoring module monitors the flow of the liquid medicine in the infusion tube in real time. Rapid pressurizing infusion and liquid medicine flow monitoring can be achieved, and infusion medication safety of a patient is guaranteed.

The utility model relates to a pressure maintaining alarm mechanism of an artery compression bag and the artery compression bag, and belongs to the technical field of medical instruments. The pressure maintaining alarm mechanism comprises a barrel, a piston, a sliding rod, balancing weights and a connector, the piston is arranged in the barrel, the sliding rod is arranged in the center of the end face of the top of the piston, and the multiple balancing weights are arranged on the sliding rod in a stacked and sleeved mode. The center of the bottom of the cylinder is connected with a connector through a communicating hose. According to the pressure-maintaining alarm mechanism and the artery pressurizing bag, the pressure in the bag body can be continuously maintained, an alarm can be given out, regular observation and pressure supplement are not needed, and the labor intensity of a plurality of pressurizing bags can be greatly reduced. The pressure in the pressurizing bag can be adjusted, so that the conveying speed can be adjusted according to personal physique, and the pain of a patient during rapid infusion can be reduced. The infusion amount can be adjusted through the scales, alarm reminding can be conducted after infusion is completed, and the labor intensity is further reduced. The problem that the labor intensity is high due to the fact that an existing pressurizing bag needs to be continuous is solved.
