The invention discloses a coronary intervention postoperative radial artery compression device and a using method thereof, and relates to the technical field of medical instruments.The coronary intervention postoperative radial artery compression device comprises a supporting frame, side supports are fixedly connected to the two sides of the supporting frame correspondingly, and hook-and-loop fasteners used for adhesion are fixedly connected to one sides of the two side supports correspondingly; supporting columns are fixedly connected to the periphery of the bottom of the supporting frame, then the supporting frame is attached to the wrist through two hook-and-loop fasteners, so that the supporting frame is pre-positioned, then a cotton swab is pulled out of a clamping piece, a pressing frame is moved to the position over a puncture position by pushing a connecting piece, and finally a fixing ring descends by rotating an inner threaded ring. And then the pressing piece on the pressing frame is driven to press the puncture position, the situation that the position needs to be repeatedly adjusted after the needle is pulled out is avoided, and it is guaranteed that the puncture point is accurately pressed.

This invention discloses an electrode implantation tool. The distal end of the electrode is provided with a fixing component. The implantation tool includes an outer sheath and an inner sheath. The inner sheath includes an inner sheath tube and a first handle. The outer sheath includes an outer sheath tube and a second handle. The inner sheath tube can be inserted into the outer sheath tube. The first handle can be locked within the second handle. The second handle has at least a first locking position and a second locking position in the axial direction, allowing the first handle to move from the first locking position to the second locking position. The inner diameter of the inner sheath tube is smaller than the outer diameter of the fixing component, and the inner diameter of the outer sheath tube is larger than the outer diameter of the fixing component. Other parts of the electrode, excluding the fixing component, can be inserted into the inner sheath tube. This invention allows for a single puncture of the electrode and implantation tool near the target nerve tissue. After successful testing, the electrode is directly released and fixed, ensuring consistency between the test point and the implantation point.

The invention discloses a biological bacteriostatic agent, a preparation method and application in prevention and control of postharvest diseases of fruits and vegetables, the bacteriostatic agent is bacillus coagulans metabolite VOCs, the preservation number of the bacillus coagulans is CGMCC NO.9951, bacteriostatic substances in the metabolite VOCs include but are not limited to benzaldehyde, acetic acid, isobutyric acid and isovaleric acid, and the bacteriostatic substances in the metabolite VOCs include benzaldehyde, acetic acid, isobutyric acid and isovaleric acid. The preparation method of the biological bacteriostatic agent comprises the following steps: diluting activated bacillus coagulans, coating the surface of an LB culture medium with the diluted bacillus coagulans, and culturing at 37 DEG C for 48 hours. The application method of the biological bacteriostatic agent in germ control in fruit and vegetable storage comprises the following steps: putting sweet potatoes and a bacillus coagulans agent in a packaging carton together, and storing in a 28 DEG C environment. The bacillus coagulans CGMCC 9951 is a generally considered safe (GRAS) strain, metabolites are safe and non-toxic, and the bacillus coagulans CGMCC 9951 is environment-friendly, convenient to produce and capable of being applied on a large scale. Chemical agents can be partially replaced for application, pesticide residues are reduced, and the storage quality of sweet potatoes is improved.
