Description

Anti-pollution ointment applicator

Technical Field

The invention relates to the technical field of medical tools in dermatology, in particular to an anti-pollution ointment applicator.

Background

In the process of treating skin diseases, the external drug therapy can directly apply the drug to the focus of a patient, so that the treatment effect is very obvious and is a main means for treating the skin diseases; however, most of the external medicines are generally in the form of paste or liquid packaged by a flexible pipe, and need to be squeezed out from the package for coating when in use, so that in the coating process, after the medicine outlet is contacted with fingers of an operator or directly contacted with a focus part of a patient, the medicine outlet of the medicine and the medicine package can be secondarily polluted, and cross infection is easily generated with other patients when the external medicines are reused in the later period, which is not beneficial to treatment and thorough rehabilitation of diseases.

Meanwhile, as the dosage of the medicines depends on the state of illness, the medicines are generally not used up at one time, and the rest medicines need to be stored in a sealed way for later use; in the process of storage, on one hand, the problem of secondary pollution exists, and on the other hand, after the medicine is stored, the medicine can be extruded out due to the influence of various external factors such as heavy pressure, temperature and the like, so that the serious waste of medical resources is caused.

In addition, the ointment is extremely convenient to apply for treatment, so that the common skin diseases do not need hospitalization, and the patients can apply the ointment according to the advice; but different from professional medical environments, the medicine is randomly stored when the medicine is used at home, and any person can contact with the medicine, so that disease infection is easily caused; in addition, the external medicine is usually prohibited for oral administration, and once a person swallows the medicine by mistake, unexpected safety accidents are caused.

In conclusion, the existing application mode of the external medicine not only is easy to cause disease transmission and cross infection among patients, medical care personnel and family members, but also has the danger of easy swallowing, and has larger medical potential safety hazard.

Disclosure of Invention

Aiming at the situation, in order to make up for the technical defects in the prior art, the invention provides an anti-pollution ointment applicator to solve the problems of secondary pollution and potential medical safety hazards in the existing external application mode.

The technical scheme for solving the problem is as follows: including the piston cylinder that the level set up, arrange the piston of the horizontal slip in the piston cylinder in, arrange the piston right side in and with piston connection's piston push rod and arrange the left daubing head of piston cylinder in, the left end of piston cylinder have the level set up extrude the hole, the last stop valve that has the control to extrude the hole circulation direction of piston cylinder, the stop valve makes the medicine in the extrusion hole can only circulate along the direction from the right side to the left side, there are a plurality of connecting rods of arranging in the stop valve periphery and along the axis circumference distribution who extrudes the hole on the piston cylinder, the one end of keeping away from the stop valve of connecting rod is connected with piston cylinder through the torsional spring rotation about, the right half of the rotation circumference of connecting rod is arranged in to the other end of connecting rod, there is the rotation spacing groove that matches with the connecting rod on the piston cylinder, rotate the spacing groove and extrude the hole and be linked together, when the connecting rod, the position of a valve core of the stop valve is locked or unlocked, and a contact surface, corresponding to the other end of the connecting rod, on the valve core is arranged in a tangent mode with the maximum rotation circumference of the connecting rod; the left end face of the piston cylinder is provided with a plurality of horizontal jacks which are communicated with the rotation limiting grooves in a one-to-one correspondence manner, the smearing head is provided with a plurality of ejector rods which are arranged on the right side of the smearing head and matched with the horizontal jacks in a one-to-one correspondence manner, and when the right end face of the smearing head is attached to the left end face of the piston cylinder, the ejector rods are completely inserted into the jacks and push the connecting rod to rotate in the rotation limiting grooves, so that the other end of the connecting rod is separated from the valve core of the stop; the smearing head is provided with a medicine outlet corresponding to the extrusion hole.

The invention has simple operation, can realize the extrusion and the smearing of the medicine by connecting the smearing head and the piston cylinder together, can be used for different patients by replacing the smearing head, and greatly facilitates the external medicine treatment operation of skin diseases; meanwhile, the medicine in the piston cylinder can be extruded only when the smearing head is installed, so that the medicine can be effectively prevented from being extruded or swallowed accidentally, and the use safety is improved.
