Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical devices, and particularly relates to a medicine ointment extruder. BACKGROUND

[0002] There are non-surgical methods such as medicine, injection and physical therapy for hemorrhoids. Regular medicines such as hemorrhoid ointment can reduce edema, relieve symptoms and reduce pain. The currently marketed hemorrhoid ointment is 4g per small branch. Generally, one branch can be used for 3-4 times. Patients generally use it continuously for 7 days. If there is no effect, further examination or other medicines are used. However, after the medicine is squeezed out from the ointment tube, it is difficult to squeeze out all the residual ointment in the ointment tube. The less the residual ointment is, the more difficult it is to control the amount of extrusion. Since the site of applying the ointment is special, patients only want to operate by themselves. When the ointment in the ointment tube is less and more difficult to squeeze out, on the one hand, patients have difficulty in verifying that enough amount has been squeezed out, which affects the effect when the amount is insufficient. On the other hand, due to the difficulty in operation, patients often discard the ointment tube with a certain amount of ointment remaining, causing a large amount of waste and polluting the environment. Thirdly, one ointment can only be used for 2-3 times, and 3-4 ointments are needed for continuous use for 7 days. Therefore, a simple ointment extruder is needed for patients to operate without visual conditions, so that the ointment in the ointment tube can be squeezed out as much as possible without residual, and the amount of extrusion is accurate each time, so that the maximum number of uses of the ointment is achieved.
