The piston composed of the first push head and the second push head is used. Since the first push head includes a retracted waist-shaped part, An isolation area is formed in the syringe, which greatly strengthens the sealing of the push head, effectively prevents air from entering, and improves the safety of the syringe. The needle device can be replaced, which saves the raw materials of the syringe and improves the environmental protection performance.

Description

Anesthesia syringe

technical field

The utility model relates to the technical field of medical equipment, in particular to an anesthesiology syringe.

Background technique

At present, the clinically used syringes are mainly composed of needles, needle tubes, pistons and needle cores. The needle tubes of this type of syringes have smooth surfaces, and it is difficult to hold them firmly when injecting patients, and it is easy to cause cross-infection; the existing syringes The front end of the push rod generally uses a disc-shaped rubber as the push head. The function of the push head is to allow the user to push the liquid in the syringe into the skin by pushing. The sealing of the disc-shaped rubber It is poor, and it is easy to bring a small amount of air into the syringe, which brings hidden dangers to users, increases the difficulty of work for nurses, and cannot meet the needs of nurses.

Utility model content

The purpose of this utility model is to provide a kind of anesthesiology department syringe in order to overcome above-mentioned technical shortcoming.

The technical solution adopted by the utility model to solve the technical problem is: an anesthesiology syringe, including a needle device and a syringe, the bottom of the syringe is provided with a needle device, the outer end of the needle device is provided with a protective cover, the needle The barrel is provided with a scale line, the top of the syringe is provided with a fixed finger rest, the inside of the syringe is provided with a piston rod, and the top of the piston rod is provided with a finger ring.

The bottom end of the syringe is provided with an external thread.

The top end of the needle device is provided with an internal thread matched with the external thread at the bottom end of the syringe.

A piston is arranged at the bottom of the piston rod, and elastic rubber is arranged on the piston.

The piston is provided with a first pusher head and a second pusher head, and the diameter of the second pusher head is larger than that of the first pusher head.

The bottom end of the needle device is provided with a needle.

The beneficial effects that the utility model has are:

The utility model has a simple structure, can be firmly held when injecting a patient, and can avoid cross-infection, thereby reducing the work difficulty of the nursing staff. The pusher head contains a retracted waist-shaped part, which forms an isolation area in the syringe, which greatly strengthens the seal of the pusher head, effectively prevents air from entering, and provides safe use of the syringe. The needle device can be replaced. , saving the raw materials of the syringe and improving the environmental protection performance.
