Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical apparatus and instruments, concretely relates to a corrugated pipe extrusion type ointment extruder. BACKGROUND

[0002] There are non-surgical methods such as drugs, injection and physical therapy for hemorrhoids. Regular drugs 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 use of other drugs is needed. However, after the medicine is squeezed out from the ointment tube, it is difficult to squeeze out all the ointment remaining in the ointment tube. The less the residual ointment is, the more difficult it is to control the squeezing amount. Since the ointment application site is special, patients only want to operate by themselves. When the ointment in the ointment tube is less and more difficult to squeeze out, patients have difficulty in verifying that enough amount has been squeezed out. This affects the curative effect when the amount is insufficient. On the other hand, due to the difficulty of operation, patients often discard the ointment tube with a certain amount of ointment remaining, causing a lot 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. The last ointment has more remaining. Therefore, a simple ointment extruder that can be operated by patients themselves without visual conditions is needed in the care of hemorrhoids. It is convenient for patients to squeeze out as much ointment as possible from the ointment tube without residual, and at the same time, the amount of extrusion is accurate, and the maximum number of ointment use is achieved.
