Description
Technical Field
The invention relates to the field of medical auxiliary instruments, in particular to a special adjusting pad for a dental chair.
Background
The patient generally lies and goes on in the dental chair when carrying out oral treatment, and current dental chair usually includes support, back and cushion, and wherein the cushion sets up on the support, and the back is connected with the cushion through connection structure, and connection structure's width is far less than the width of back and cushion.
In order to facilitate the operation of the doctor, the patient needs to keep the posture of lying on the back during the treatment, and in order to avoid the patient from sliding down when lying on the back, the current chair is usually provided with a groove to be opposite to the hip of the patient for limiting the position of the patient. When general anesthesia treatment is carried out, intubation is needed before treatment, a patient needs to lie down and the head needs to lean back when intubation is carried out, the backrest and the cushion of the existing dental chair can only be adjusted to be V-shaped but cannot be adjusted to be horizontal completely, and the patient cannot lie down. Secondly, when the patient is a child, the groove on the cushion also prevents the child from lying down, and because of the limited space and other reasons in the treatment room of the department of stomatology, a sickbed is not usually arranged, so that general anesthesia treatment can be carried out on the dental chair.
At present, the common practice is to fill articles such as bed sheets in the grooves of the seat cushion and the gaps between the backrest and the seat cushion, so that the buttocks and the back waist of the child lie on the filled articles. However, in actual operation, the thickness of the bed sheet is limited, and more bed sheets are needed to achieve the leveling effect; the bed sheet has no elasticity, the flatness of the upper surface and the same hardness of each part cannot be guaranteed, the longest time required by general anesthesia treatment can reach 3 hours, and the comfort level of the bed sheet is lower after the bed sheet is laid on the packed bed sheet for a long time; and the bed sheet can be reused after being cleaned and disinfected after being used, and the bed sheet is more in quantity, so that the workload of cleaning and disinfecting is greater, and the use is inconvenient.
Disclosure of Invention
The invention aims to provide a special adjusting cushion for a dental chair, which is used for filling up the space between the backrest and the chair of the existing dental chair, so that a child can lie on the dental chair flatly.
In order to achieve the purpose, the invention adopts the following technical scheme: a special adjusting cushion for a dental chair comprises a lower supporting unit, a positioning unit and a flexible supporting unit, wherein the lower supporting unit comprises a first base plate and a second base plate, and the first base plate is hinged with the second base plate; the positioning unit is arranged on the first base plate or the second base plate and comprises two positioning assemblies, each positioning assembly comprises a fixing block, a U-shaped block and a locking piece, the fixing blocks are arranged on the first base plate or the second base plate, and the locking pieces are used for pushing the U-shaped blocks to one side far away from the fixing blocks; the flexible supporting unit comprises a flexible layer and a winding roller, one end of a flexible net is installed on the first base plate, the other end of the flexible net is fixed on the winding roller, the winding roller is rotatably connected with the second base plate, and a positioning block used for positioning the winding roller is arranged on the second base plate.
