Description

A skin applicator

technical field

The invention belongs to the field of medical devices, in particular to a skin drug applicator.

Background technique

In daily life, skin allergies, injuries and skin diseases are very common in daily life. When the skin is allergic or injured, it is generally necessary to apply disinfectants or therapeutic drugs to the affected area. For patients with skin diseases, it is necessary to apply drugs regularly . At present, the most common method of applying medicine is to dip a cotton swab or cotton wool into the affected area to apply the medicine. This method is slow in efficiency and difficult to spread evenly. The liquid is easy to pollute. In the prior art, it is usually directly applied with a cotton swab or ointment. Direct application with a cotton swab will cause the medical surface on the cotton swab to fall off, which will cause a small amount of cotton to be mixed with the ointment, which will affect the use of the ointment, and the cotton swab will stick. After taking the ointment and applying it, most of the ointment will remain on the cotton swab, which will cause a waste of ointment, and using the ointment bag to apply it directly and apply it with a cotton swab will cause a certain pulling force on the skin, which is not good for the healing of the affected area.

Although there are also some devices based on the principle of rolling-ball drug discharge, these devices use the surface of the ball to dip the drug solution and apply it on the patient's skin during the rolling process. waste.

Contents of the invention

In view of this, the object of the present invention is to provide a skin drug applicator to solve the waste of ointment caused by the uncontrollable drug delivery speed of the skin drug applicator in the prior art.

In order to achieve the above object, the technical scheme adopted by a kind of skin drug applicator of the present invention is:

A skin applicator comprising:

case;

Drug storage cavity: set in the shell, the drug storage cavity is cylindrical;

Connecting port: set on the shell, the connecting port communicates with the medicine storage chamber, and the connecting port is used for fixed connection with the ointment bag;

Drug outlet: opened on the shell, the drug outlet is connected with the drug storage chamber, and the drug outlet is fixedly connected with the drug applicator;

The first connecting column: vertically fixed on the housing, the first connecting column is sleeved with a first spring;

The second connecting column: vertically fixed on the housing, the second connecting column is sleeved with a second spring;

Handle: one end is sleeved on the first connecting column, the other end is sleeved on the second connecting column, the first spring and the second spring are both located between the handle and the housing;

Lifting structure: the height is adjustable and set on the top of the first connecting column, and the lifting structure is set correspondingly to the connecting port, so as to facilitate the lifting and positioning of the tail of the ointment bag;

Extrusion structure: arranged between the lifting structure and the connection port, the extrusion structure is relatively arranged on the handle to squeeze the ointment bag with the movement of the handle to squeeze the ointment to the medicine storage chamber;

Airbag: fixed on the housing, the airbag is arranged between the first connecting rod and the second connecting rod, the handle is fixed with an extrusion plate, and the extrusion plate is fixedly connected with the airbag;

Regulating chamber: set in the housing, the regulating chamber is connected to the airbag, and the regulating chamber is provided with regulating components;

Regulating plate: it is rotated and arranged in the medicine storage cavity, and the regulating plate is connected with the regulating assembly, so that when the ointment is squeezed out more, the regulating plate rotates to adjust the amount of ointment discharged from the medicine outlet.

Beneficial effects: when the skin drug applicator of the present invention is in use, the ointment bag is directly fixed on the drug applicator through the connection port and the lifting structure, and the ointment is squeezed from the ointment bag to the drug storage chamber through the extrusion structure, Apply the ointment to the affected area of the skin through the applicator head fixed at the drug outlet, avoid directly applying the cotton swab or ointment bag on the affected area of the skin, and minimize the pulling of the skin on the affected area by the cotton swab or ointment bag during application, so as to avoid damage to the affected area Secondary damage to the skin; in addition, when the skin drug applicator of the present invention is used for drug application, through the setting of the adjustment chamber, the adjustment assembly, and the adjustment plate, when there are more ointments extruded at one time, it can be adjusted by the inclination angle of the adjustment plate. The speed of dispensing the ointment avoids excessive extrusion of the ointment at one time, which not only causes waste of the ointment, but also tends to spread unevenly, which affects the efficacy of the medicine.

Further, the adjustment chamber is arranged directly below the drug storage chamber, and the adjustment assembly includes a piston plate that is slidingly sealed in the adjustment chamber, and the side of the piston plate facing the air inlet is connected to the front of the adjustment chamber with a spring, and the piston plate A U-shaped connecting rod is fixed on the side of the plate facing away from the air inlet, and the other end of the U-shaped connecting rod extends into the medicine storage chamber and is hingedly connected with the regulating plate; The rod is in sliding and sealing cooperation with the medicine storage cavity.
