This utility model discloses a tilted, convenient medicine bottle holder for surgery. The main body of the medicine bottle holder is tilted at 45°. After the medicine bottle is placed, the bottom of the bottle contacts the anti-slip pad to avoid collision with the main body of the medicine bottle holder and thus prevent the bottom of the bottle from breaking. It can be arranged according to different sizes of medicine bottles, improving the applicability of the equipment. The labels on the information card slots on the main body of the medicine bottle holder are replaceable, which is convenient for marking and replacement. This avoids the problem of circulating nurses holding medicine bottles to medical staff on the operating table to draw liquids, which may cause injury, occupational exposure, or contamination and loss due to needles hitting the bottle wall, resulting in unnecessary waste. The main body of the medicine bottle holder 1 has a 6-compartment structure. After the medicine bottle is opened, it is placed in the compartment, and then the liquid is drawn through a syringe. This effectively avoids accidental injury to the operator and makes the liquid draw more complete, which is in line with the types and quantities of commonly used drugs in surgery (such as anesthetics, antibiotics, and emergency drugs), and avoids mixing.

This invention discloses a non-contact induction anesthesia device for mouse modeling, belonging to the field of veterinary instrument technology. The anesthesia device includes a cage with a wire mesh structure, inside which a movable partition divides the cage into a rearing area and an anesthesia area. A sealing plate is fixed to one side of the cage, with an opening on the sealing plate leading to an anesthesia chamber. The anesthesia chamber is equipped with a sealing gate and a push-pull compartment. The push-pull compartment has a support compartment and an end cap, the end cap of which can close the opening of the anesthesia chamber. The anesthesia chamber has an air inlet and an air outlet. In use, the operator pushes the partition outside the cage to drive the mouse into the anesthesia chamber, closes the sealing gate, and introduces anesthetic gas through the air inlet. After the mouse is anesthetized, the push-pull compartment is pulled out to remove the mouse. This invention avoids handling mice by hand, reducing stress and occupational exposure risks. Simultaneously, the sealing structure effectively controls the escape of anesthetic gas, improving the safety and efficiency of experimental operations.

This application provides a novel tabletop ventilation device, relating to the field of reproductive toxicity testing technology for non-clinical safety evaluation. It includes a hood and an exhaust duct. The hood is generally polyhedral, with an openable and closable door on at least one side. One end of the exhaust duct is connected to at least one hood, and the other end is connected to an exhaust system for discharging air from inside the hood to the outside of the laboratory. The hood is placed on a tabletop within the laboratory. The internal space of the hood is used to accommodate a microscope and specimens. The hood has an observation window, and the eyepiece of the microscope can be aligned with the observation window. By covering the microscope with the hood, the internal space of the hood is relatively sealed, which can confine the formaldehyde gas volatilized from formalin to a controllable area. When specimens are placed inside the hood for operation, the external exhaust system can provide power to promptly expel the air containing formaldehyde and other pollutants from the hood, effectively reducing the occupational exposure risks of respiratory damage and skin allergies for laboratory personnel.

This invention discloses a puncture needle for flying needle blood collection, comprising a puncture needle tube, a needle hub, and a needle handle. The opening direction of the beveled tip of the puncture needle tube is consistent with the extension direction of the needle handle, and the angle between the central normal of the beveled tip and the gripping plane of the needle handle is ≤15°. The needle handle and needle hub are integrally injection molded, and the tail end of the puncture needle tube is fixedly connected to the needle hub. This invention locks the beveled tip and the gripping direction of the needle handle in the same direction, ensuring that the nurse's force direction during flying needle blood collection is consistent with the cutting direction of the needle tip, achieving a cutting-type puncture, reducing puncture resistance by more than 60%, and significantly alleviating patient pain. This invention also provides a needlestick injury prevention blood collection connector with a retractable needle tip; the needle tip automatically retracts after blood collection, eliminating occupational exposure risks. This puncture needle is predictable in operation, highly standardized, safe, and reliable, suitable for mass production and clinical application.

The present application relates to the technical field of medical devices, and discloses a head dressing change pad, which comprises at least three substrates, namely a first substrate, a second substrate and a third substrate; the first end of the first substrate, the second substrate and the third substrate is connected to the same base shaft, and the first substrate, the second substrate and the third substrate have a rotation degree of freedom around the base shaft; the first substrate, the second substrate and the third substrate are respectively provided with a first semicircular hole, a second semicircular hole and a third semicircular hole, and any two semicircular holes constitute a through hole for wearing on the neck. The present application integrates the skin preparation, dressing change and tube removal operation on the same dressing change pad by adopting a three-fold structure and a composite design of the water absorption layer and the waterproof layer, and wraps the medical waste in the garbage disposal protective pad surface after the operation is completed, thereby preventing blood and disinfectant leakage and hair scattering, and reducing the risk of cross infection and occupational exposure of medical staff.

This invention discloses a perioperative remote multi-channel drug delivery system, belonging to the field of multi-channel drug delivery technology. Key technical features include: hardware comprising disposable sterile infusion tubing, a main unit integrating a three-way control and peristaltic pump module, a controller equipped with an UNO control board, and a power supply. The system supports independent and precise drug delivery through three channels, capable of single-dose administration of 1mL, 3mL, and 5mL. It communicates with a mobile app via Bluetooth, enabling remote execution of commands such as drug delivery, flushing, emergency stop, and automated anesthesia induction. It incorporates a 100ms-level non-blocking emergency stop safety logic and a full-process voice feedback mechanism, and presets multiple automated anesthesia induction schemes. This system can reduce the risk of occupational exposure and cross-infection for medical staff, and is suitable for various scenarios such as routine surgery, radiation operating rooms, and infectious disease wards, significantly improving perioperative drug delivery efficiency and safety.
