[0002] Pre-hospital emergency care refers to emergency care for critically ill patients outside the hospital. In a broad sense, pre-hospital emergency care refers to emergency rescue performed on the spot by medical staff or witnesses when a patient becomes ill, while in a narrow sense, pre-hospital emergency care refers to medical activities such as on-site rescue and on-the-way monitoring performed by professional emergency care institutions that are composed of communication equipment, transportation tools, and basic medical elements before the patient arrives at the hospital. Pre-hospital emergency care can rescue patients as soon as possible. For critical situations such as cardiac and respiratory arrest and severe trauma, timely pre-hospital emergency care can save the patient's life. After receiving a call for help, go to the scene immediately for rescue or transportation, first rescue and then transportation. Emergency care environment conditions are affected by the scene. On-site emergency care includes first aid in the wild, on the roadside, in a deformed car, and during transportation. Light, noise, and vibration will bring difficulties to nursing operations such as auscultation, measurement of vital signs, and injection. In summary, the current pre-hospital emergency treatment process has the following technical problems: arriving at the emergency site and transporting the patient to the hospital requires an emergency vehicle, on which emergency equipment and medicines must be prepared, and existing emergency medicines are fixed by simple means, such as rubber bands, which are inconvenient to operate during emergency treatment and difficult to organize, resulting in a chaotic placement of medicines. After the emergency treatment, the medicines need to be replenished, and the standard for the order of use of medicines in drug use management is that the first-placed medicine should be used first, and the last-placed medicine should be used last. The existing organization method cannot distinguish the order of medicine placement time; at the same time, bumps are inevitable on the emergency vehicle, and the placed medicines may tip over, leading to other problems.

After the medicine is placed, the cover plate (131) is buckled, and the ball (133) on the cover plate (131) is locked in the buckle groove (105). At the same time, the cover plate (131) presses and pushes the pressure rod (313). The pressure rod (313) pulls the inclined block (311), so that the tension spring (303) pulls the limit block (304) to reset, and the rack (302) and the gear (301) are meshed. At the same time, the ratchet (214) and the ratchet wheel (203) are engaged. The rotating column (202) rotates to drive the conveyor belt (2) to drive the driving frame (201) close to the outer frame (1) to move toward the buckle groove (102). The movable frame (201) drives the medicine to move to the buckle groove (102), and the medicine is limited by the limit plate (110) and will not fall out from the empty space between the cover plate (131) and the inner frame. When it is needed, the medicine is pushed by the finger through the buckle groove (102), the limit plate (110) is pushed open and the medicine is taken out. Under the action of the tension spring (303), the driving frame (201) pushes the next medicine to fill the position; it is suitable for working in a bumpy emergency vehicle, is not affected by inversion, rollover and other actions, keeps the medicine in the taking operation position, and at the same time limits the medicine placement structure, cooperates with the pushing part so that the use order meets the use standard of first put first use, and last put last use.
