The invention discloses an automatic needle unloading structure. The automatic needle unloading structure comprises a support and a pushing and unloading part; the support is used for being fixed to the outer side of a needle base and located below a needle head; the pushing and unloading part is movably connected to the support; the support is provided with a guide structure for supporting and guiding the pushing and unloading part to do reciprocating motion; the pushing and unloading part is provided with a needle unloading inclined shovel; and the upper surface of the needle unloading inclined shovel is used for making contact with the lower end of the needle head, and the upper surface of the needle unloading inclined shovel is obliquely arranged relative to the moving direction of the pushing and unloading part. The purpose of automatic needle unloading can be achieved after operations such as infusion or blood sampling and the like are completed, operation is easy, clinical use is not affected, and therefore the probability that medical workers are punctured is greatly reduced, and safe and effective protection is achieved. The invention further discloses an infusion device comprising the automatic needle unloading structure.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic needle unloading structure and an infusion device. Background technique [0002] According to statistics, 80% to 90% of the causes of blood-borne infectious diseases among healthy medical staff are caused by needle-point stab wounds, and nurses account for 80% of the stabbed medical staff. The hospital attaches great importance to promoting the prevention of infectious diseases, effectively avoiding the injury and cross-infection caused by venous needle sticks to medical staff, and providing a safe and healthy medical environment for patients and medical staff, which is the goal that the medical care industry is committed to achieving. [0003] In order to prevent medical staff from being stabbed by the needle tip, the common solution in the prior art is to set a device on the needle seat for covering or wrapping the needle. The structure is that a needle pr...
