After the needle is used, the blood of the patient remains, when the blood of the patient contains infectious substances such as viruses, bacteria and the like, the substances can be the infection sources of infectious diseases, such as AIDS, hepatitis, syphilis and the like, and once the needle is infected, the treatment difficulty is extremely high, and huge physical and psychological damage can be caused to the infected person. Therefore, there is a need to safely dispose of the needle, usually by placing the used needle in a special sharps collection box, and to avoid direct manual access to the needle during disposal. Some needle unloading devices are also available in the prior art, but most of the needle unloading devices are in a clamping and pulling mode, namely, a needle head is clamped into the device and pulled out of a needle cylinder, so that the needle head is separated from the needle cylinder. The needle unloading device needs to be fixed at a certain position by adopting a clamping and pulling mode, or the needle unloading device is pressed by the other hand, so that the needle unloading device is inconvenient to move and operate. There are also devices using electric needle-removing device, but the electric driving device and the transmission structure and control device are introduced, resulting in complicated structure of the needle-removing device, relatively high manufacturing cost, and relatively complicated and simple operation because each evidence-obtaining still needs to connect the power supply and turn on the switch. Therefore, it is necessary to design a needle unloading device which is simple in operation, safe and convenient in needle taking process, free in movement of the needle unloading device and convenient to move to a proper position for use.
Chinese patent application publication No. CN204543146U, published as 2015, 08 and 12, entitled "a needle removing device", discloses a needle removing device, which consists of a motor, two meshed identical gears, two clamping jaws, two eccentric axles, two sliding axle sleeves and a support; the two clamping jaws, the two eccentric wheel shafts and the two sliding shaft sleeves are arranged in a mirror symmetry manner, and the motor drives the two eccentric wheel shafts through two meshed same gears; when the needle head extends into the space between the teeth of the clamping jaws of the needle head removing device, the sensor triggers the micro switch to start the motor, power is transmitted to the eccentric wheel through two meshed same gears, the eccentric wheel shaft drives the eccentric wheel sleeve to generate repeated action of forward, downward, backward and upward, and therefore the sliding shaft fixed on the eccentric wheel sleeve drives the clamping jaws to generate repeated action of clamping jaws tightly and releasing upward. However, the electric needle removing device provided by the patent is relatively complex in structure, can be used only by connecting a power supply and turning on a switch, and is inconvenient to use.
