A syringe is a common medical device. The gas or liquid is withdrawn or injected mainly with a needle. The emergence of syringes is an epoch-making revolution in the field of medical appliances. The process of withdrawing and injecting gas or liquid with a needle is called injection. The syringe consists of a syringe with a small hole at the head end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out, the liquid Or the gas is inhaled from the small hole at the head end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in.

Medical syringes can be used for injecting, outputting and aspirating various liquids. Generally, various medicaments are injected into the subcutaneous, muscle, blood vessels or other tissues and organs of the human body or animals, or from the tissues and organs of the human body or animals. Suction of various liquids.

Syringes are also commonly used in ophthalmic treatments. Syringes used in the treatment of ophthalmic diseases are usually slender and long, and have various specifications. The commonly used ones are 1mL syringes. The injection principle is the same as that of existing conventional syringes. The tail end of the piston push rod in the syringe barrel realizes suction and injection operation). When injecting and withdrawing, it is necessary to push the piston push rod to the bottom or pull it out completely. For medical staff, it is particularly difficult to operate with one hand.

Push the push seat to the farthest from the head end of the barrel, and the dose of medicine drawn is 1mL. When pushing out the medicine, push the push seat to the closest to the head end of the barrel, and the rubber piston connected to the other end of the push rod just reaches the end of the barrel.

The utility model is further configured as follows: the top of the rubber piston is conical.

By adopting the above technical solution, the conical shape can be fitted to the head end of the barrel to ensure that the medicament is completely pushed out.

The utility model is further configured as follows: the push seat includes a cylindrical plug, a connecting rod and a thumb buckle, the cylindrical plug fits with the inner wall of the cylinder, and the connecting rod extends through the chute to the cylinder and is connected with the thumb buckle.

By adopting the above technical solution, the cylindrical plug fits closely with the inner wall of the cylinder, and the stability of the device is higher when pushing, and it is not easy to shake. The design of the thumb buckle allows the medical staff to push in and suck the medicine according to their own operation conditions. Put your thumb through the ring-shaped thumb buckle and hook the thumb buckle, making it easier to apply force for pushing and sucking.

In summary, the utility model has the following beneficial effects:

In the side push syringe of the utility model, the movement of the push rod in the cylinder is realized by pushing the push seat on the side wall of the cylinder body. Compared with conventional syringes, the pushing distance of the push rod of the syringe in this solution is shorter, and the operator can use one hand The action of extracting the medicinal solution and injecting the medicinal solution is completed, making the operation of extracting the medicinal solution and injecting the medicinal solution more convenient.
