Description

Medical pedal sharp machine box

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to medical foot-operated sharp machine box.

Background

Sharp ware is wounded to be the main occupational hazard that clinical medical personnel face, in the clinical care work, nursing staff will accomplish a large amount of injections every day, blood sampling and infusion work, the chance of contact syringe, transfusion system and syringe needle etc. is more, the probability that takes place sharp ware and injures is also bigger, the effect of medical sharp ware collection box is the effective measure that prevents and reduce operator sharp ware and injure, medical personnel cut sharp-pointed medical supplies such as syringe needle down with the scissors, then throw into in the sharp ware box of disposable, fill up the whole waste product dustbin of throwing into of back seal processing, the people that can avoid waste product processing is injured by the mistake once more like this. However, because scissors and sharp machine box are separately, during the use, need look for the scissors to because the scissors sets up when the outside of sharp machine box is used, sharp machines such as syringe needle collapse easily, fall outside sharp machine box, medical personnel often have increased unsafe hidden danger because of not accomodating the sharp machine in the sharp machine box.

The sharp instrument box adopted in the clinical work at the present stage is a PP medical yellow sharp instrument box which is divided into a round shape and a square shape.

Further, the first connector 301 and the second connector 302 have the same structure, and the first connector 301 includes: the ring 303 is connected with the support rod 304, and the ring 303 is sleeved on the fifth connecting rod 206.

The first connecting piece 301 is the same as the second connecting piece 302 in structure, and can ensure the moving direction of the fifth connecting rod 206 through the two connecting pieces, and can also ensure that the fifth connecting rod 206 still can better complete the work of cutting a sharp instrument after a certain connecting piece is damaged, thereby avoiding the problem that the scissors cannot cut due to the damage of one connecting piece.

Further, the scissors assembly comprises: scissors, connecting shaft 403 and spring 404; the scissors include: the knife comprises a first knife 401 and a second knife 402, one end of the first knife 401 and one end of the second knife 402 are connected with a spring 404, the other end of the first knife 401 and the other end of the second knife 402 are connected with a connecting shaft 403, and the two sides of the first knife 401 and the second knife 402 are connected with a fifth connecting rod 206.

The scissors are divided into two parts which are similar to scissors used in manual operation and are divided into a first knife 401 and a second knife 402, and the first knife 401 and the second knife 402 have the same structure and opposite directions.

The first knife 401 and the second knife 402 are positioned on the upper surface and the lower surface, and the cutting edges of the first knife 401 and the second knife 402 are tangent to cut off sharp instruments.

The connecting shaft 403 can connect one ends of the first and

second blades

401 and 402 together so that the first and

second blades

401 and 402 both rotate about the connecting shaft 403.

One end of the connecting shaft 403 is fixed on the top end surface of the second cavity 105, thereby fixing the position of the scissors.

The scissors are arranged below the inlet 103 on the top end face of the sharp instrument box main body 1, and when medical staff throw the abandoned sharp instrument into the sharp instrument box 106 in the sharp instrument box main body 1 through the inlet 103, the scissors can cut off the sharp instrument.
