Description

Medicine applying device for affected parts of skin

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medicine applying device for a skin affected part.

Background

In various hospitals, skin cleaners are often needed for patients with skin diseases or patients with skin abrasion and burn, such as cleaning cotton swabs and the like to clean the skin injury positions of the patients, then skin medicine applying devices are used, such as medical cotton sticks or medicine liquid squeezing balloons and the like to apply medicine to the skin injury positions of the patients, however, the cotton on the cotton balls is subjected to cotton removal in the using process, so that part of cotton threads are easily embedded into the skin injury parts of the patients, and further infection is caused, and when medicine is applied for the second time, the corresponding medical cotton sticks infected with residual liquid at the skin injury parts of the patients are inserted into the corresponding medical medicine bottles again to pick up the medicine, the medicine in the whole medical medicine bottles is easily infected, and the patients cannot be given to other people for subsequent use; when the medicine liquid is directly smeared in a mode of extruding the medicine liquid, the dosage of the medicine liquid is difficult to control, the situation of back suction of the medicine liquid is possibly caused, the infection of the medicine is caused, and the use cost of the medicine is increased; when the medicine applying device is not used, part of patients can also directly pour the solution medicine on the hands and directly apply the solution medicine on affected parts by fingers, so that the risk of bacterial infection is increased, and the common external medicine such as glucocorticoid solution can cause the conditions of finger skin atrophy, hirsutism, telangiectasia and the like after long-term use.

Some medicine applicators are hair disease medicine applicators, are designed in a tooth comb form, cannot be applied to alopecia areata, alopecia totalis and rare hair type scalp hair diseases, are not sufficiently dispersed in medicine feeding density, need to clearly comb the teeth after each use, are inconvenient and easy to pollute.

Chinese patent application CN206659726U discloses an improved skin cleaning applicator; comprises a liquid storage handle, a skin cleaning head and a skin medicine applying head; the skin cleaning head is arranged on the outer wall of the lower end of the liquid storage handle; the skin medicine applying head is arranged below the liquid storage handle; the bottom of the liquid storage handle is provided with a liquid medicine outflow hole, an elastic control piece for opening/blocking the liquid medicine outflow hole is arranged in the liquid medicine outflow hole, and the connecting end of the skin medicine applying head is inserted into the liquid medicine outflow hole and connected with the elastic control piece; in a natural state, the elastic control piece blocks the liquid medicine outflow hole; when pressing skin medicine applying head end to make skin medicine applying head connecting end push up the elastic control piece to open the liquid medicine outflow hole, the liquid medicine in the liquid storage handle flows out from the liquid medicine outflow hole. The effect is as follows: stock solution handle is used for saving the quantitative liquid medicine that needs to use, make avoid causing the waste of liquid medicine and the infection of bottled medicine, skin cleaning head and skin medicine loading head are made integratively, also make and to enable the greatly reduced cost and save resources, but its outflow through elastic control piece control liquid medicine, and need press skin medicine loading head end during the use, need apply certain pressure to medicine loading department promptly, just can realize paining of liquid medicine, this can bring secondary damage for the wound undoubtedly, especially to the new wound, it is bigger to cause the possibility of secondary damage.

Chinese patent application CN206239884U discloses a scalp care device, which comprises an applying device, a medicine containing device and an extruding device, wherein a cavity for containing liquid medicine is formed in the medicine containing device; the smearing device is arranged at the front part of the medicine containing device and is communicated with the cavity; the extrusion device is arranged at the rear part of the medicine containing device and is used for extruding the liquid medicine in the cavity. The beneficial effects are as follows: by arranging the smearing device, the liquid medicine can be contacted with the scalp to the maximum extent, so that the liquid medicine is prevented from being wiped off by the hair in the process of smearing the liquid medicine on the scalp, and the treatment effect is greatly improved; by arranging the extruding device, the control of the amount of the liquid medicine applied to the scalp can be realized, and the device is convenient and practical. In the technical solution described in this patent document, the drug containing device can be loaded with solid and liquid drugs, and the drugs are extruded out by the extrusion device through the application device. However, the smearing device adopts a design of a liquid medicine delivery pipe, the medicine applying mode is equivalent to injecting medicine on the surface of a wound through a syringe, and the effect of uniform control cannot be realized for liquid medicine.

In summary, there is a need for a device for applying a drug to skin affected parts, which can achieve uniform application, flexible use, controllable dosage, and convenient precise application of liquid drug to the scalp, and avoids adverse drug reactions caused by bacterial infection and drug application to fingers.
