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 the anti-reflux applicator for dermatology, which aims to solve the problems of secondary pollution and potential medical safety hazards in the existing external medicine application mode.
The technical scheme for solving the problem is as follows: the ball valve comprises a piston cylinder, a piston push rod and a coating head, wherein the piston cylinder is horizontally arranged, the piston slides horizontally in the piston cylinder, the piston push rod is arranged on the right side of the piston and connected with the piston, the coating head is arranged on the left side of the piston cylinder, an extrusion hole is horizontally arranged at the left end of the piston cylinder, a ball valve for controlling the extrusion hole to open and close is arranged on the piston cylinder, a gear which coaxially rotates with a valve rod of the ball valve is arranged on the piston cylinder, a volute spiral spring is wound on the valve rod, one end of the volute spiral spring is connected with the valve rod, the other end of the volute spiral spring is connected with the piston cylinder, and the valve rod rotates under the torsion action of the volute spiral spring to enable the ball valve to be in a closed state; the smearing head is provided with a horizontally arranged rack arranged on the right side of the smearing head, the left end face of the piston cylinder is provided with a jack matched with the rack, a part of gear teeth of the gear are arranged in the jack, and the smearing head is provided with a horizontally arranged medicine outlet corresponding to the extrusion hole; when the smearing head moves rightwards, the rack enters the jack and is in meshing transmission with the gear, the ball valve gradually opens the extrusion hole along with the rotation of the gear, and meanwhile, the medicine outlet hole is gradually close to the extrusion hole.
The invention has simple operation, can realize the extrusion and the smearing of the medicine only by connecting the smearing head with the piston cylinder, and does not need to worry about the mutual infection or the cross infection among patients, medical care personnel and family members; meanwhile, the medicine in the piston cylinder can be extruded only when the smearing head is installed, so that the medicine can be prevented from being extruded in the process of storing or transporting the medicine, and the situation that the medicine is extruded and swallowed can not occur.
