Description

Medical spraying device for scald treatment

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical spraying device for scald treatment.

Background

Low-heat scalds are common in scalds and can be called low-temperature scalds. Is a scald caused by the skin being in contact with a low-heat object higher than the body temperature for a long time. Skin may be scalded by exposure to a temperature of 70 ℃ for one minute; when the skin is exposed to a temperature of approximately 60 ℃ for more than five minutes, scald may also occur, which is called low temperature scald. Generally, the skin is contacted with a low-temperature heat source for a short time, which causes only blister-type scald of the superficial dermis, but if the low-temperature heat source is continuously applied, the scald gradually progresses to scald of tissues of the deep dermis and subcutaneous layers.

If chinese patent application No. CN201420580602.4, discloses a scald treatment medical flush coater of 2015-01-07, including the storing shell of making by silica gel material, the inside of storing shell is three-layer structure, the outmost is the infusion chamber, the inlayer is for leading to whitewashed chamber, the intermediate level is for ventilating the chamber, the front portion of storing shell is equipped with a plurality of fumaroles, every fumarole all communicates with the inside chamber of ventilating of storing shell, the front rear portion of storing shell is equipped with a plurality of holes of dusting, every hole of dusting all communicates with the inside chamber of leading to whitewashed of storing shell, the front intermediate position of storing shell is equipped with the aseptic cotton layer, the aseptic cotton layer communicates with the inside infusion chamber of storing shell, the storing shell is external to have the breather pipe, liquid pipe and the powder pipe of leading to of being made by plastic materials. The air injection hole of the utility model aims at the affected part scalded by the patient, so that the pain of the patient can be effectively reduced; the liquid through pipe is externally connected with liquid medicine, the liquid medicine permeates into the disinfection cotton layer, and the liquid medicine can be coated on the affected part of a patient through the disinfection cotton layer; the powder tube is externally connected with a medicine water source, and the powder spraying hole can spray medicine powder to the affected part of a patient, so that the treatment is convenient.

The above document still has the following disadvantages: 1. when the existing medicine applying device is used, the liquid medicine can fly when the liquid medicine is discharged from the spray head, so that the situation that the liquid medicine is intensively applied to the affected part of the skin is not facilitated, and the waste of resources is caused; 2. scribble the medicine device and lack the structure that the ration goes out the medicine, can not be accurate quantitative spout the medicine processing to the affected part promptly, because the condition that drips can appear in too much liquid medicine, not only cause the wasting of resources but also can be infected with the surrounding environment, still can not be even scribble on patient's burn epidermis.

To this end, we propose a medical spray device for scald treatment to solve the above problems.
