Description

Quantitative ointment smearing device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a quantitative ointment smearing device.

Background

For patients with skin disease, ointment is generally applied to the affected part for treatment. The ointment is commonly in the form of a flexible tube squeeze, i.e., the ointment is transferred from the tube to the affected area by a squeezing operation. However, this procedure has drawbacks, such as the "proper" application of the ointment to the affected area is generally described in the physician's order or instructions. However, this amount is not precisely defined for different conditions. In the extrusion process, the problems of insufficient ointment, excessive ointment and the like are easy to occur. Under the condition of insufficient ointment, the treatment efficiency is easy to be reduced and the treatment time is prolonged; in case of excessive ointment, side effects are easy to occur.

In addition, the hose extrusion mode has the problems that ointment cannot be completely extruded, and the ointment is wasted. For example, in the case where the remaining amount of ointment is not large, it is necessary for the patient to repeatedly fold and bend the tail of the hose so as to squeeze the remaining ointment toward the head of the hose. However, this procedure is laborious and does not allow the entire ointment to be squeezed onto the hose head.

When the ointment is applied to the affected part by a patient, the ointment is applied by the finger of the patient generally without auxiliary tools, so that part of the ointment is easy to remain on the finger, the dosage of the ointment is further inaccurate, and the normal finger skin is affected by the medicine residue.

At present, no effective solution is proposed for solving the problems that the ointment cannot be quantitatively extruded, the extrusion process is time-consuming and labor-consuming, the ointment is easy to waste, the ointment is not easy to uniformly spread, the dosage of the ointment is inaccurate and the like in the related technology.
