Compared with the prior art, the transit transport vehicle has the beneficial effects that the work environment of sanitation workers is improved, the work efficiency is improved, and safety and reliability are achieved.

The invention relates to a system for conveying therapeutic drugs. The system comprises an injection catheter, an injection needle and an operating handle. The injection needle is communicated with the injection catheter via fluid, the operating handle is fixedly connected to the near end of the injection catheter, a buffer device is arranged at the far end of the injection catheter, and the injection needle is partially or completely arranged in the buffer device. When the far end of the buffer device is pressed, the axial length of the buffer device is reduced, and the needle tube of the injection needle stretches out of the buffer device. By means of the system, the risk of leakage of injection drugs is significantly lowered, the fit adaptability in the cardiac contraction and relaxation process is improved, and the probability of breakage of the injection needle is reduced; the system is simple in overall design, safe and convenient to operate and easy to use.

The invention discloses a protector for preventing joints from moving quickly, and belongs to the field of medical instruments for the orthopedics department. The protector comprises a near-end fixing part (4), a far-end fixing part (3), a myoelectricity control device and a connecting device, wherein the near-end fixing part (4) is fixed on a joint near-center end limb (1), the far-end fixing part (3) is fixed on a joint far-center end limb (2), and the connecting device is respectively connected with the near-end fixing part (4) and the far-end fixing part (3). The myoelectricity control device is used for sensing muscle signals corresponding to the joints and controlling the connecting device. When the joint is slowly bent and stretched, the near-end fixing part (4) and the far-end fixing part (3) do free relative movement; when the joint is suddenly and rapidly bent and stretched, the connecting device prevents relative movement between the near-end fixing part (4) and the far-end fixing part (3), and therefore the joint is prevented from being damaged.

The invention provides a blue-light external subtitle display applied to PS4 electronic equipment.
