Abstract: A particle storage tube (100) used for implanting microparticles into a body in cooperation with a puncture needle (500), and comprising an accommodation portion (1) and a drug delivery portion (2). The accommodation portion (1) is an elongated hollow tube having a channel (10) used to accommodate microparticles (4). One end of the accommodation portion (1) is connected to the drug delivery portion (2), and the other end of the accommodation portion (1) is an open part (11) used to discharge the microparticles out of the particle storage tube (100). The inner diameter of the channel (10) is 1.0-1.8 times the inner diameter of a lumen (502) of the puncture needle (500). An inner chamber (20) of the drug delivery portion (2) is in communication with the channel (10), and is used for delivering liquid medicine (200) to the channel (10).

Abstract: A gas-liquid delivery connector, a gas-liquid delivery connector pair, and a gas-liquid delivery device. The gas-liquid delivery connector comprises: a male connector (1) for connecting a catheter, wherein the male connector (1) is provided with a first connecting channel (11) in the axial direction thereof; and a female connector (2) for connecting a microcatheter, wherein the female connector (2) is provided with a second connecting channel (21) in the axial direction thereof. The female connector (2) is connected to the male connector (1) such that the second connecting channel (21) is in butt joint with and in communication with the first connecting channel (11), and the inner diameter of the second connecting channel (21) is the same as the inner diameter of the first connecting channel (11).

Abstract: Disclosed are oxygen-containing particles, a manufacturing method therefor, and a use thereof. The oxygen-containing particles comprise a carrier that is safe for the human body and has a large number of micropores or pores distributed on the surface. The oxygen-containing particles further comprise a peroxide crystal attached to the surface of the micropores or pores of the carrier. The oxygen-containing particles in the present invention have the advantage of having microparticles in addition to a slow and controllable release of oxygen. The oxygen-containing particles can achieve local or systemic oxygen supply during embolization, implantation, perfusion and other operations. Furthermore, the oxygen-containing particles can also be used alone to supply oxygen for patients with pulmonary dysfunction.

Abstract: 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.

Abstract: A microparticle for drug loading, a drug loading microparticle, a particle containing tube, and an implantation system for the microparticle. The microparticle for drug loading includes a housing (31) and a drug loading part (34) located inside the housing and is used for being implanted into body tissues by means of a puncture needle (5); the housing (31) is provided with at least one micro-hole (33) running through the wall thickness of the housing (31); and the drug loading part (34) is located inside the housing (31) and is used for loading drugs. The microparticle for drug loading/drug loading microparticle can achieve different types of drug loading and different release speeds, can be directly implanted into tissues, and have the technical advantages of both microspheres and radioactive particles.
