The syringe for soft ointment can deliver the soft ointment smoothly and painlessly by using the flexible contact of the arc-shaped head. Injecting into the anus not only ensures that the amount of soft ointment sent into the anus reaches the required index, but also effectively overcomes the waste of medicine.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A syringe for soft ointment, comprising an injection tube, a connecting cap, a push rod, a piston and a pressing block, one end of the injection tube is set as an arc-shaped head with a bullet structure, and a cavity is provided in the middle of the injection tube. The cavity is connected to the end of the arc-shaped head through a conduit, and an external thread B is provided on the outer edge of the other end of the injection tube; side wings are respectively provided on both sides of the connecting cover, and a perforation is provided in the middle of the connecting cover , the inner side of the lower part of the connecting cover is provided with an internal thread corresponding to the external thread B of the injection tube; the external thread A provided at one end of the push rod is connected with the briquetting block, and the other end of the push rod is provided with a piston, and the outer edge of the piston There is a rubber ring on the surface, and the rubber ring set on the outer edge of the piston slides closely with the cavity in the middle of the injection tube. B wire connection.

In the syringe for soft ointment, a connecting seat is provided at the lower part of the pressing block, and the external thread A of the push rod is connected with the connecting seat.

In the syringe for soft ointment, the arc-shaped head has a circular arc-shaped transition.

Due to the above-mentioned technical scheme, the utility model has the following beneficial effects:

The syringe for soft ointment described in the utility model utilizes the flexible contact of the arc-shaped head to overcome the discomfort of delivering medicine in the anus, and the utility model can make the soft ointment be smoothly and painlessly sent into the anus; Simple and easy to operate.
