Provided are .sup.82Sr/.sup.82Rb elution systems that accept patient weight as a input function in order to determine an optimal quantity of radioactive rubidium-82 for delivery to a patient pursuant to an imaging scan. Also disclosed are systems that deliver a saline flush to remove residual .sup.82Rb from the system downstream of the generator, and preferably deliver the removed residual .sup.82Rb to the patient. Other disclosed systems measure the total volume of saline that flows through a .sup.82Sr/.sup.82Rb generator, a total volume of saline that flows through the generator and through a bypass line, or a total volume of saline received by a waste reservoir, in order to monitor system components so that optimal system functioning is assured.

The present disclosure provides methods of preparing a medical solution. In some aspects, the medical solution can be prepared from mixing a first liquid with a second liquid or mixing a solid component with a liquid in an autoinjector. In some aspects, the heat released from the mixing can promote solubility of a dry medicament in the solution.

A device for conveying a biological material includes a body including an aperture configured to enable connection with an outside of the body and a chamber configured to store a biological material, a plurality of conveyors accommodated in the body and configured to convey the material, and a driver configured to select one of the plurality of conveyors, align the selected conveyor with the aperture, and move the selected conveyor to the outside of the body through the aperture.

A device includes an inflatable balloon, a reservoir disposed within the inflatable balloon, a needle compartment attached to the balloon and to the reservoir, an injection needle disposed within the needle compartment, and an inflation mechanism. The reservoir contains a therapeutic preparation. The inflation mechanism is structured to inflate the balloon, and upon inflation, the injection needle is structured to enter the reservoir. A method includes making an autoinjector available to a subject with instructions to ingest the autoinjector. The autoinjector is structured to inject a therapeutic preparation into a wall of a gastrointestinal tract of the subject responsive to ingestion of the autoinjector. The autoinjector includes an injection needle disposed in a needle compartment attached to a reservoir. The injection needle is initially separated from the reservoir, and is structured to enter the reservoir for delivery of the fluid therapeutic preparation through the needle into the wall.

Provided herein are the safety features for radiopharmaceutical infusion system for treatment or diagnostic purpose, wherein infusion system comprises a controller, a source of radiopharmaceutical including other components. The controller is configured to perform automated quality control steps at the start of the system during daily quality control and ensure that system complies to desired technical attributes prior to administration to patients. The quality control steps comprise calibration, breakthrough testing, checking for unauthorized connection and/or malware in the system, network or other connected devices.

Disclosed are a pharmaceutical preparation with a tracing function, and a delivery system therefor. The pharmaceutical preparation comprises a first drug and a second drug in a liquid or gaseous state, wherein the first drug and the second drug are each divided into multiple sections, which are arranged in series at intervals in a conduit. One of the first drug and the second drug is a tracer drug that can be developed in a medical imaging device in the human body. The first drug and the second drug are immiscible and satisfy compatibility requirements. The pharmaceutical preparation can comprise an aerobic contrast agent, an aerobic embolic agent and an aerobic perfusion agent. Same can be applied to a variety of contrast techniques by means of a one-step simple operation, saving the dosage of a drug while maintaining a high concentration of the drug.

A device for administering needle-free subcutaneous treatment to a patient comprises an actuator configured to deliver a plurality of volumes of a treatment at a plurality of locations on a body of the patient; at least one imaging device configured to detect a movement of the needle-free device from a first location on the body of the patient to a second location on the body of the patient; and a processor configured to determine the second location on the body of the device relative to the first location from the movement of the needle-free device relative to the first location on the body, the processor further configured to determine a volume of the plurality of volumes of the treatment to deliver to the body of the patient at the second location.

A syringe includes a syringe body, a first plunger, a second plunger, and an inner tube. The syringe body defines a syringe port in fluid communication with a syringe cavity. The first plunger is disposed within the syringe cavity and defines a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The second plunger is disposed within the syringe cavity, the first plunger and the second plunger cooperatively defining a second chamber in the syringe cavity. The inner tube comprises an inner tube lumen, wherein the inner tube and a first plunger shaft lumen of a first plunger shaft define an annulus therebetween, the annulus in fluid communication with a first plunger channel of the first plunger and the annulus permits fluid communication between the syringe port and the first plunger channel.

A surgical instrument for delivering fluids or other agents or materials to an injection site, such as a surgical, treatment or tissue site. The surgical instrument comprises a multiple dispensing unit housing needle configured to house a plurality of fluid or materials dispensing units, or sub-needles, a needle cover sleeve, and an outer cannula. The surgical instrument is configured to provide fluid or materials to multiple areas of a surgical or treatment site during a single injection period, without having to remove the needle and re-insert to position it to inject fluid to another area of the surgical or treatment site.
