The invention belongs to the technical field of radiopharmaceutical injection, and particularly relates to a radiopharmaceutical injection device which comprises a hollow protective barrel, a protective cover is in threaded connection with the top wall of the protective barrel, and the inner circumferential wall of the protective cover and the inner circumferential wall of the protective barrel are in smooth transition. A partition plate is fixedly connected to the inner circumferential wall of the protective barrel, a movable plate is longitudinally connected to the inner circumferential wall of the protective barrel in a sliding mode, the partition plate divides the space of the inner wall of the protective barrel into an air pressure cavity and an injection cavity, and an injection hole is formed in the bottom wall of the protective barrel and communicates with the injection cavity; before radioactive medicine is injected, blood vessels are guaranteed to be unobstructed, after injection is completed, residual medicine is removed and injected into the body of a patient, vasospasm can be monitored in real time when the radioactive medicine is injected, and when spasm is caused by the medicine, injection of the radioactive medicine is stopped, and medical staff can conveniently intervene in time.

The present invention relates to an interventional surgical puncture robot, comprising a base device, the bottom of which has a walking device for moving to a target area, a host mounted thereon for receiving information, storing information, processing information, and sending instruction information; the top of the base device supports a head and arm device for completing information recognition and finger positioning, and the robot comprises two robotic arms; one robotic arm end is connected to a first finger device for locating the puncture point of the puncture surgery; the other robotic arm end is connected to a second finger device for puncture; wherein the first finger device and the second finger device are both capable of grasping, replacing, and installing surgical instruments, and the two cooperate to complete the puncture surgery. The present invention realizes robotic puncture surgery, improves the accuracy of puncture, thereby reducing the occurrence of repeated operations due to inaccurate puncture positions, which may cause vascular spasms, and improves the safety of puncture surgery.

This invention discloses a traditional Chinese medicine composition for improving diarrhea, belonging to the field of traditional Chinese medicine technology. Addressing the shortcomings of existing antidiarrheal techniques, which only treat the symptoms and not the root cause, have significant side effects, high recurrence rates, and easily cause damage to the intestinal microcirculation, this invention is based on the original microscopic pathogenesis of small intestinal microvascular spasm and ischemia, and abnormal intestinal fluid metabolism. It is prepared by combining peppermint, angelica dahurica, nutmeg, cinnamon, platycodon grandiflorus, and angelica sinensis. The synergistic effect of each herb can target and relax spasmodic small intestinal microvessels, restore normal intestinal blood perfusion, regulate intestinal peristalsis rhythm, bidirectionally regulate intestinal fluid secretion and reabsorption, and simultaneously block abnormal stress signals in the brain-gut axis, repairing intestinal microcirculatory damage. This invention has a scientifically formulated composition, mild medicinal properties, and no side effects. It addresses the root causes of various acute, chronic, and functional diarrheas caused by cold stimulation, emotional stress, and spleen deficiency with cold stagnation, exhibiting strong curative effect and an extremely low recurrence rate, possessing high clinical promotion and application value.

The therapeutic device for use in blood vessels includes a catheter and a microvalve. A flexible, low-friction, reconfigurable cover is attached to or near the distal end of the microvalve. The cover is deployed between the occluder and the vessel wall and intervenes between the occluder and the vessel wall as the occluder moves relative to the vessel wall, reducing the occurrence of vascular spasm.

Muscle, tendon, and vessel spasm, cramping, inflammation and related symptoms are treated with high doses of magnesium without ingestions, injection, or topical application. A therapeutic patty is formed with a desired load of magnesium (for example magnesium powder) combined with an emulsifier, such as microcrystalline cellulose, and plant oil. The combination is mechanically stirred to form a firm patty and then shaped into a desired form. The patty may be wrapped in various fabric. In use, the patty is placed near a patient's skin, though not necessarily in physical contact, to provide the therapeutic effect.

This invention relates to the field of interventional tumor therapy technology and discloses a real-time optimization method for interventional radiotherapy planning. The method includes: dimensionality reduction processing of preoperative three-dimensional angiography images to generate an initial three-dimensional spatial radiation dose distribution matrix; acquisition of in-situ physical and electrophysiological physical quantities corresponding to the injection phase, outputting multimodal synchronous temporal features; analysis of the multimodal synchronous temporal features based on feature decoupling and cross-tissue dielectric cross-validation logic to exclude vasospasm and arteriovenous shunt states, and calculation of dynamic flow resistance increments; reconstruction of blood flow distribution ratios based on dynamic flow resistance increments, accumulating to generate a real-time cumulative radiation dose distribution matrix; monitoring the real-time cumulative radiation dose distribution matrix and catheter reflux pressure gradient, sending a low-level command when a threshold is reached to stop the operation of the radiation-proof high-pressure injection pump. This invention solves the problem of deviation between actual radiation dose distribution and static plan, preventing excessive radiation in non-target areas and microsphere reflux.
