Abstract
Description
Technical Field
[0001] The invention relates to the field of medical auxiliary equipment, and in particular to a special adjustment pad for a dental chair. Background Art
[0002] Patients generally lie on a dental chair during oral treatment. Current dental chairs usually include a bracket, a backrest and a cushion, wherein the cushion is arranged on the bracket, and the backrest is connected to the cushion through a connecting structure, and the width of the connecting structure is much smaller than the width of the backrest and the cushion.
[0003] In order to facilitate the doctor's operation, the patient needs to maintain a reclining posture during treatment. In order to prevent the patient from sliding down when lying back, the current seats are usually provided with grooves to oppose the patient's buttocks to limit the patient's position. During general anesthesia treatment, intubation is required before treatment, and during intubation, the patient needs to lie flat with the head tilted back. The backrest and seat cushion of the current dental chair can usually only be adjusted into a V shape, and cannot be completely adjusted to a horizontal shape, so the patient cannot lie flat. Secondly, when the patient is a child, the grooves on the seat cushion also make it impossible for the child to lie flat. Due to limited space and other reasons, beds are usually not set up in the dental treatment room, so general anesthesia treatment can only be performed on the dental chair.
[0004] At present, the common practice is to stuff bed sheets and other items in the grooves of the seat cushion and the gap between the backrest and the seat cushion, so that the child's buttocks and lower back area lie on the stuffed items. However, in actual operation, the thickness of the bed sheet is limited, and more bed sheets are needed to achieve the filling effect; moreover, the bed sheet has no elasticity, and it is impossible to ensure that the upper surface is flat and the hardness of each part is the same. The time required for general anesthesia treatment can be up to 3 hours, and lying on the stuffed bed sheet for a long time is not comfortable; moreover, the bed sheet needs to be cleaned and disinfected before it can be used again. Due to the large number of bed sheets, the workload of cleaning and disinfection is large, and it is inconvenient to use. Summary of the invention
[0005] The present invention is intended to provide a special adjustment pad for a dental chair, so as to fill the space between the backrest and the seat of the current dental chair, so that a child can lie flat on the dental chair.
[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a special adjustment pad for a dental chair, comprising a lower support unit, a positioning unit and a flexible support unit, the lower support unit comprising a first pad and a second pad, the first pad being hinged to the second pad; the positioning unit is arranged on the first pad or the second pad, the positioning unit comprises two positioning components, the two positioning components both comprise a fixed block, a U-shaped block and a locking piece, the fixed block is mounted on the first pad or the second pad, the locking piece is used to push the U-shaped block to a side away from the fixed block; the flexible support unit comprises a flexible layer and a winding roller, one end of the flexible net is mounted on the first pad and the other end is fixed on the winding roller, the winding roller is rotatably connected to the second pad, and a positioning block for positioning the winding roller is provided on the second pad.
[0007] The beneficial effects of this program are:
[0008] 1. The adjustment pad in this solution is placed on the current dental chair for use. When in use, the first pad and the second pad are respectively against the backrest and the seat cushion of the dental chair. The adjustment pad can be connected to the dental chair by clamping the U-shaped block on both sides of the connection structure between the backrest and the seat cushion, and the adjustment pad is positioned to prevent the adjustment pad from sliding left and right relative to the dental chair. At this time, the flexible layer is stretched between the first pad and the second pad, and the flexible layer is higher than the position of the seat cushion close to the backrest. The flexible layer can support the child's buttocks and lower back, and can increase the height of the child's buttocks and lower back, so that the child can maintain a lying or nearly lying posture, which is convenient for general anesthesia treatment.
[0009] 2. The flexible layer in this solution is relatively soft and more comfortable when used for a long time. In actual use, the adjustable angles between the backrest and the seat cushion of different dental chairs are different. In this solution, the first pad and the second pad can be adjusted according to the angle between the backrest and the seat cushion, and the flexible layer can be rolled up by the winding roller, and the length of the flexible layer between the first pad and the second pad can be adjusted to ensure that the flexible layer can support the child.
[0010] 3. The angles of the first pad and the second pad can be adjusted: the angle between the first pad and the second pad can be adjusted to an obtuse angle or an acute angle. When the angle is an obtuse angle, the first pad and the second pad are in a V-shape with the opening facing upward, and the child is supported by the flexible net; when the second pad is rotated until the positioning unit is located between the first pad and the second pad, and the angle is an acute angle, the first pad and the second pad can be placed on the seat cushion with the opening facing the backrest, and the child is supported by the first pad or the second pad. Compared with the flexible net, the adjustment pad is suitable for dental chairs with a small gap between the backrest and the seat cushion or even no gap.
[0011] 4. When the gap between the backrest and the seat cushion of the dental chair is small and an armrest is provided on the seat cushion, the first pad or the second pad on which the fixing block is installed can be placed on the seat cushion with the side provided with the fixing block facing upward, and the U-shaped block is clamped on the inverted U-shaped armrest to position the adjustment pad. Therefore, the adjustment pad in this scheme is suitable for dental chairs of different shapes.
[0012] Furthermore, through slots are provided on the first pad and the second pad, and the two ends of the flexible layer pass through the two through slots respectively.
[0013] The beneficial effect of this solution is that the through groove in this solution can limit the flexible layer to prevent the flexible layer from sliding laterally relative to the first pad and the second pad.
[0014] Furthermore, the cross section of the through groove is in the shape of an arc.
[0015] The beneficial effects of this solution are as follows: the contact area between the through groove and the flexible layer is larger, which can better support the flexible layer; and the arc-shaped through groove has no side ridges, which can prevent the flexible layer from being damaged.
[0016] Further, the ends of the flexible net are mounted on the first pad by bolts.
[0017] The beneficial effect of this solution is that the end of the flexible net in this solution that is connected to the first pad can be removed, so that the flexible net can be easily cleaned.
[0018] Furthermore, a plurality of fixing holes are provided on the first pad or the second pad along the width direction, and a fixing rod which can be aligned with any one of the fixing holes is rotatably connected to the fixing block.
[0019] The beneficial effect of this solution is that the fixing block can be installed at different positions on the first pad or the second pad through different fixing holes, thereby ensuring that the U-shaped block can be stuck on the connection structure between the backrest and the seat cushion.
[0020] Furthermore, the fixing hole is a threaded hole, and the fixing rod is threadedly matched with the fixing hole.
[0021] The beneficial effect of this solution is that the fixing block can be quickly fixed by screwing the fixing rod into the threaded hole, and the installation is convenient.
[0022] Furthermore, a plurality of positioning holes are sequentially provided on the first pad or the second pad along the length direction, and the fixing rod can be aligned with any of the positioning holes.
[0023] The beneficial effect of this solution is that when the adjustment pad is adjusted to a state where the angle between the first pad and the second pad is an acute angle and the fixing block is located between the first pad and the second pad, the angle between the first pad and the second pad is determined by the fixing block and the U-shaped block, and the installation position of the fixing block can be adjusted along the length direction through the positioning hole to adjust the angle between the first pad and the second pad, thereby changing the supporting effect of the adjustment pad on children, and being suitable for use with dental chairs of different body shapes and sizes.
[0024] Furthermore, the flexible layer is a flexible mesh.
[0025] The beneficial effect of this solution is that compared with the common sheet-like flexible layer, the flexible net in this solution is more breathable and more comfortable to use in summer.
[0026] Furthermore, a buffer layer is fixed on the flexible layer.
[0027] The beneficial effect of this solution is that the buffer layer can further improve the comfort of the flexible net.
[0028] Furthermore, a handle is slidably fitted on the winding roller in the axial direction, and a receiving groove for receiving the handle is provided on the positioning block.
[0029] The beneficial effect of this solution is that the winding roller can be rotated more conveniently by the handle to wind up the flexible layer, and after the handle is slid into the receiving groove, the handle can be positioned by the positioning block to prevent the flexible layer from automatically loosening.

[0033] The following is further described in detail through specific implementation methods:
[0034] The reference numerals in the drawings of the specification include: a first pad 1 , a fixing hole 11 , a second pad 2 , a flexible layer 3 , a positioning block 4 , a receiving groove 41 , a fixing block 5 , a locking member 51 , a U-shaped block 6 , a guide rod 61 , and a handle 7 .
[0035] Example
[0036] A special adjustment pad for a dental chair, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a lower support unit, a positioning unit and a flexible support unit. The lower support unit includes a first pad 1 and a second pad 2. The right end of the first pad 1 is hinged to the left end of the second pad 2. The front and rear ends of the second pad 2 are both provided with fixing plates, and the two fixing plates are opposite to the right end of the first pad 1. In actual implementation, the fixing plates can be installed by welding or screws, or can be integrally formed with the second pad 2. Taking the fixing plate on the front side as an example, a plurality of through holes are provided on the first pad 1 along the circumference, and a plurality of locking holes aligned with the through holes are provided on the first pad 1. The locking holes in this embodiment are threaded holes. After rotating the first pad 1, the bolts are passed through the through holes and screwed into the aligned locking holes to position the first pad 1 and the second pad 2.
[0037] The positioning unit is arranged at the bottom of the first pad 1. The positioning unit includes two symmetrical positioning components. Each positioning component includes a fixed block 5, a U-shaped block 6 and a locking member 51. The first pad 1 is provided with a plurality of fixing holes 11. Specifically, the plurality of fixing holes 11 are distributed along the length and width of the first pad 1. The fixing holes 11 in this embodiment are also threaded holes. The fixing block 5 is provided with a fixing rod. The fixing rod in this embodiment is a screw. After the screw passes through the fixing block 5 and is screwed into the fixing hole 11, the fixing block 5 is installed on the first pad 1. In actual implementation, the fixing hole 11 can also be a smooth inner wall. In this case, the fixing rod passes through the fixing hole 11 and is fixed by bolts. The two U-shaped blocks 6 are both located between the two fixing blocks 5, and the openings of the two U-shaped blocks 6 are opposite. The U-shaped block 6 is welded with two guide rods 61 toward the side wall of the fixing block 5. The guide rod 61 passes through the fixing block 5 horizontally and cooperates with the fixing block 5 with a small gap, so that the U-shaped block 6 can slide relative to the fixing block 5. The locking member 51 passes through the fixing block 5 transversely and is threadedly connected to the fixing block 5 . The end of the locking rod abuts against the U-shaped block 6 and is used to push the U-shaped block 6 toward a side close to the other U-shaped block 6 .
[0038] The flexible support unit includes a flexible layer 3 and a winding roller. Specifically, the flexible layer 3 is a flexible net. The flexible layer 3 in this embodiment is a mesh structure formed by criss-crossing steel strands, so that the flexible layer 3 is relatively soft and has greater strength. In actual implementation, a buffer layer is glued or fixed on the upper surface of the flexible layer 3 by needle and thread. Specifically, the buffer layer can be any material such as sponge, latex, cotton, cotton cloth, etc.; the buffer layer can also be formed by coating any material such as sponge, latex, cotton, cotton cloth, etc. on the steel strands forming the flexible net.
[0039] The left end of the first pad 1 and the left and right ends of the second pad 2 are all provided with through grooves, and the cross-sections of the through grooves in this embodiment are all arc-shaped. The left end of the flexible layer 3 passes through the through groove on the first pad 1 and is installed on the first pad 1 by screws; the right end of the flexible layer 3 passes through the through grooves on the right and left ends of the second pad 2 in turn, and extends to the space between the first pad 1 and the second pad 2. The winding roller is located in the space between the first pad 1 and the second pad 2, and the right part of the buffer layer is welded to the winding roller.
[0040] Two positioning blocks 4 are provided on the upper surface of the second pad 2. The two positioning blocks 4 are detachably connected to the left and right ends of the second pad 2. Specifically, the positioning blocks 4 in this embodiment are connected to the second pad 2 by screws. The two positioning blocks 4 are respectively located on the front and rear sides of the first pad 1. The two ends of the winding roller respectively penetrate the two positioning blocks 4 and rotate with the positioning blocks 4. A rectangular groove is provided at the front end of the winding roller, and a connecting block is slidably fitted in the rectangular groove. The cross-sections of the connecting block and the rectangular groove are both rectangular. A handle 7 is welded to the front end of the connecting block; the front side wall of the positioning block 4 is provided with a receiving groove 41 for receiving the handle 7.
[0041] The specific implementation process is as follows:
[0042] When used on a dental chair with a gap between the backrest and the seat cushion, the first pad 1 is attached to the backrest, the second pad 2 is attached to the second pad 2, and then the fixing plate is fixed to the first pad 1 by bolts to position the first pad 1 and the second pad 2. Then install the positioning unit. During installation, determine the installation position according to the connection structure between the backrest and the seat cushion, so that the two U-shaped blocks 6 are respectively located on both sides of the connection structure, and the opening of the U-shaped block 6 is facing the connection structure. Then push the two U-shaped blocks 6 to the side close to the connection structure through the locking member 51 until the two U-shaped blocks 6 are respectively stuck on both sides of the connection structure, and position the first pad 1 and the second pad 2 through the cooperation between the connection structure and the U-shaped block 6. Then slide the handle 7 forward out of the receiving groove 41, and turn the handle 7 to roll up the flexible layer 3. After rolling up, slide the handle 7 into the receiving groove 41 to prevent the flexible layer 3 from loosening. During treatment, the buttocks and lower back of the child fall on the flexible layer 3, and the buttocks and lower back of the child are lifted by the flexible layer 3, so that the child can maintain a lying position or a nearly lying position.
[0043] When used on a dental chair with a small gap between the backrest and the seat cushion, the fixing block 5 is installed on the upper surface of the first pad 1, and then the first pad 1 is rotated clockwise until the angle between the first pad 1 and the second pad 2 is an acute angle, at which time the fixing block 5 and the U-shaped block 6 are against the second pad 2. The flexible net is then rolled up by the winding roller so that the flexible net is stretched between the ends of the first pad 1 and the second pad 2. If the diameter of the flexible net after the winding roller rolls up the flexible net is small due to the length of the flexible net being too long, the positioning block 4 can be installed on the right end of the second pad 2 to prevent the positioning block 4 and the winding roller from obstructing the first pad 1.
[0044] When the first pad 1 and the second pad 2 are in use, the second pad 2 is placed on the seat cushion with the tensioned flexible net facing the backrest. At this time, the fixed block 5 and the U-shaped block 6 support the first pad 1. The child's buttocks are lifted by the first pad 1, and a small amount of bed sheet is placed under the child's lower back to support the child's lower back. At this time, the flexible layer 3 can block the inserted bed sheet to prevent the bed sheet from falling between the first pad 1 and the second pad 2. Therefore, even if a bed sheet is used at this time, the amount used is far less than that of complete support with a bed sheet.
[0045] In actual implementation, a plurality of positioning holes can be further provided at the left end of the first pad 1 along the length direction. At this time, the installation position of the fixing block 5 can be adjusted along the length direction of the first pad 1. By changing the distance between the fixing block 5 and the hinge position between the right end of the first pad 1 and the second pad 2, the supporting effect of the fixing block 5 on the first pad 1 can be changed. Finally, the angle between the first pad 1 and the second pad 2 can be changed, thereby changing the lifting effect of the first pad 1 on the child's buttocks.
[0046] When using a dental chair with inverted U-shaped armrests at the front and rear ends of the seat cushion, the bottom of the first pad 1 is placed on the seat cushion, the bottom of the second pad 2 is placed against the backrest, and the opening of the U-shaped block 6 is facing the armrest. When fixing the first pad 1, the locking member 51 pushes the U-shaped block 6 toward the vertical portion of the armrest, so that the U-shaped block 6 is stuck on the vertical portion of the armrest, and the first pad 1 can also be positioned through the armrest.
[0047] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
