Description

Technical Field

[0001] The invention relates to the technical field of medical facilities, in particular to a chair used in a pediatric consulting room. Background Art

[0002] There are usually chairs for patients in the hospital's consulting room, so that patients can sit on the chairs during the consultation, communicate with the doctor about their condition more easily and comfortably, and complete some relatively simple routine examinations in a sitting position. Generally speaking, the chairs for patients in most departments are ordinary chairs, and the same is true for pediatric consulting rooms. When pediatric patients are young, they usually cannot sit steadily on their own. During the consultation, parents are required to sit on the chairs and hold their children to communicate with the doctor, and cooperate with the doctor to perform corresponding examinations on the pediatric patients. This reality has two shortcomings. On the one hand, the burden on the parents of pediatric patients is heavy during the consultation, and they are prone to physical fatigue. If the diagnosis time is long, it may even cause upper limb pain. This discomfort makes it impossible for the parents of pediatric patients to communicate with the doctor wholeheartedly, affecting the efficiency of diagnosis. On the other hand, pediatric patients usually stick close to their parents and keep a fixed posture while being held, which makes it difficult to adjust the patient's posture, which is not conducive to the doctor's corresponding examination operations on pediatric patients. Summary of the invention

[0003] The technical purpose of the present invention is to provide a pediatric chair with reasonable structural design, convenient and quick use, which can effectively improve the comfort of pediatric patients and their parents during medical treatment, so as to improve the efficiency of disease communication and facilitate examination operations.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0005] A pediatric chair, which comprises a chair body, the chair body comprising a seat board, a plurality of chair legs providing support for the seat board, and a backrest board fixed to the rear end of the seat board, characterized in that a supporting mechanism is arranged on the chair body, and the supporting mechanism comprises a support shaft, a corner shaft sleeve and a cantilever; the support shaft is fixed to the upper side of a corner of the front end of the seat board, extends in the vertical direction and has a locking hole on the rear side wall of the upper end; the corner shaft sleeve is composed of a vertical shaft sleeve and a horizontal shaft sleeve fixedly connected, the vertical shaft sleeve is communicated with the inner cavity of the horizontal shaft sleeve, the vertical shaft sleeve is sleeved on the outside of the support shaft and the two are rotatably matched so that the horizontal shaft sleeve can rotate around the support shaft in a horizontal plane, and the side wall of the horizontal shaft sleeve is provided with a guide groove extending in a spiral shape; a support plate is fixed to one side of the cantilever, and a plug-in shaft is provided at one end The plug-in shaft is inserted into the horizontal sleeve to provide support for the cantilever, and a guide pin extending into the guide groove is fixed on the plug-in shaft; the guide pin and the guide groove cooperate to limit the rotation angle of the plug-in shaft in the horizontal sleeve and cause the plug-in shaft to produce axial displacement during rotation; when the cantilever extends in the front-to-back direction and the guide pin is located at the beginning of the guide groove, the front end of the plug-in shaft is inserted into the locking hole so that the vertical sleeve and the support shaft cannot rotate relative to each other, and the support plate is upright and located at the lower side of the cantilever. At this time, the supporting mechanism is in a hand-held state, and the cantilever can be used as an armrest; when the guide pin is located at the terminal end of the guide groove, the support plate is in a horizontal state and cannot rotate downward, and the plug-in shaft retracts into the horizontal sleeve without hindering the relative rotation of the vertical sleeve and the support shaft. At this time, the supporting mechanism is in a supporting state, and the cantilever and the support plate can be used for pediatric patients to sit on them.

[0006] The usage and working principle of this pediatric chair are as follows:

[0007] In clinical applications, when the pediatric patient is too young to sit alone, the supporting mechanism is adjusted to the supporting state. At this time, the parent can sit on the chair body and make the pediatric patient sit on the cantilever and the horizontal tray. During the examination, the parent only needs to support or hug the pediatric patient without bearing the weight of the pediatric patient. In this state, the vertical shaft sleeve and the support shaft can rotate relative to each other. During the consultation, the parent can rotate and adjust the position of the tray and the cantilever by pushing and pulling, so as to adjust the body position and position of the pediatric patient, thereby improving comfort and enabling the doctor to perform necessary physical examinations on the pediatric patient more conveniently and quickly according to clinical needs; when the pediatric patient does not need to sit on the tray, the cantilever is rotated to a position extending forward and backward, and the cantilever is rotated to adjust the supporting mechanism to the hand-holding state. At this time, the tray is upright and located on the lower side of the cantilever, does not take up extra space, and can prevent the pediatric patient from sliding off one side of the seat board. The cantilever is located on the upper side of the seat board and cannot be rotated and moved, so it can be used as an armrest.

[0008] Furthermore, in the above-mentioned pediatric chair, the backrest and the seat are provided with cushions.

[0009] Furthermore, in the above-mentioned pediatric chair, the plug-in shaft and the cantilever are an integrated structure and are made of the same metal material.

[0010] Furthermore, in the above-mentioned pediatric chair, the vertical shaft sleeve and the horizontal shaft sleeve in the corner shaft sleeve are connected by welding.

[0011] Furthermore, in the above-mentioned pediatric chair, the corner sleeve is made by bending a metal tube sleeve, and the two sections formed by bending are respectively a vertical sleeve and a horizontal sleeve.

[0012] Furthermore, in the above-mentioned pediatric chair, the cantilever and the support plate are covered with a soft material layer.

[0013] Furthermore, in the above-mentioned pediatric chair, the support plate is made of a low-density composite material, and its main body adopts a hollow structure.

[0014] Furthermore, in the above-mentioned pediatric chair, the seat board and the backrest board are an integrated structure.

[0015] Furthermore, in the above-mentioned pediatric chair, the edge of the support plate is provided with a retaining edge to prevent the pediatric patient from slipping off.

[0016] Furthermore, in the above-mentioned pediatric chair, when the guide pin moves from the starting end to the end end of the guide groove, the plug-in shaft rotates 270°.

[0017] Compared with the prior art, the pediatric chair disclosed in the present invention has the following technical effects:

[0018] The pediatric chair is based on an ingenious structural design, so that the supporting mechanism has two different working states, supporting and hand-holding, to meet different actual clinical needs. The two working states can be switched by simple operation, which is convenient and quick to use. In the supporting state, the cantilever and the support plate can provide stable support for the pediatric patient, which greatly reduces the burden on the parents of the pediatric patient during the medical treatment, so that both the parents and the pediatric patient can maintain a comfortable state during the medical treatment, especially the parents of the pediatric patient can communicate with the doctor about the condition wholeheartedly, which improves the efficiency and effect of diagnosis. In the supporting state, the position of the cantilever and the support plate can be rotated and adjusted, that is, the position of the pediatric patient can be adjusted to meet the different comfort requirements of different users, and enable the doctor to examine the specific body parts of the pediatric patient more conveniently and quickly. In the hand-holding state, the support plate does not take up extra space and can prevent the pediatric patient from sliding off one side of the seat board, while the cantilever cannot be rotated and moved but is in a stable state, and can be used as an armrest, so that the pediatric chair is still more comfortable than an ordinary chair in this state.

DETAILED DESCRIPTION

[0034] See also Figure 1-8 As shown, the present invention discloses a pediatric chair, which includes a chair body and a supporting mechanism; the chair body includes a seat plate 5, a plurality of chair legs 8 that provide support for the seat plate 5, and a backrest plate 6 fixed to the rear end of the seat plate 5. The chair body can be specifically implemented with reference to the relevant chair structure in the prior art; the supporting mechanism includes a support shaft 14, a corner shaft sleeve and a cantilever 3; the support shaft 14 is fixed to the upper side of a corner of the front end of the seat plate 5 and extends in the vertical direction. The rear side wall of the upper end of the support shaft 14 is provided with a blind hole shaped locking hole 10; the corner sleeve is composed of a vertical sleeve 1 and a horizontal sleeve 2 fixedly connected, forming a right angle, the vertical sleeve 1 is connected to the inner cavity of the horizontal sleeve 2, the vertical sleeve 1 is sleeved on the outside of the support shaft 14 and the two are rotated together, so that the horizontal sleeve 2 can rotate around the support shaft 14 in the horizontal plane, and the side wall of the horizontal sleeve 2 is provided with a guide groove 9, and the guide groove 9 extends in a spiral shape; a support plate 4 is fixed to one side of the cantilever 3, and a plug-in shaft 1 is provided at one end of the cantilever 3 3, the plug-in shaft 13 is inserted into the horizontal sleeve 2 to provide support for the cantilever 3, and a guide pin 12 extending into the guide slot 9 and cooperating with the guide slot 9 is fixed on the plug-in shaft 13; the guide pin 12 cooperates with the guide slot 9 to limit the rotation angle of the plug-in shaft 13 in the horizontal sleeve 2 and cause the plug-in shaft 13 to generate axial displacement during the rotation process; when the cantilever 3 extends in the front-to-back direction and the guide pin 12 is located at the beginning of the guide slot 9, the front end of the plug-in shaft 13 is inserted into the locking hole 10 so that The vertical sleeve 1 and the support shaft 14 cannot rotate relative to each other, and the support plate 4 is in an upright state and is located at the lower side of the cantilever 3. At this time, the supporting mechanism is in a hand-held state, and the cantilever 3 can be used as an armrest; the cantilever 3 drives the plug-in shaft 13 to rotate, and when the guide pin 12 is located at the terminal end of the guide groove 9, the support plate 4 is in a horizontal state and cannot rotate downward, and the plug-in shaft 13 retracts into the horizontal sleeve 2 without hindering the relative rotation of the vertical sleeve 1 and the support shaft 14. At this time, the supporting mechanism is in a supporting state, and the cantilever 3 and the support plate 4 can be used for pediatric patients to sit on them.

[0035] The usage and working principle of this pediatric chair are as follows:

[0036] See also Figure 3 , 4As shown in Figure 8, in clinical applications, when the pediatric patient is too young to sit alone, the cantilever 3 is used to drive the plug-in shaft 13 to rotate. When the guide pin 12 is located at the terminal end of the guide groove 9, the plug-in shaft 13 cannot continue to rotate, that is, the supporting mechanism is adjusted to the supporting state. At this time, the support plate 4 is horizontal and cannot rotate downward. In addition, the support plate 4 is located on one side of the cantilever 3, and the support plate 4 can stably maintain the above state. At this time, the parent can sit on the chair body and let the pediatric patient sit on the support plate 4 and the cantilever 3. During the examination, the parent only needs to support or hug the pediatric patient without bearing the weight of the pediatric patient, which greatly reduces the burden on the parents of the pediatric patient during the medical examination and makes the pediatric patient and their parents feel comfortable during the medical examination. It can maintain a relatively comfortable state, especially the parents of pediatric patients can communicate with the doctor about the condition attentively, which improves the efficiency and effect of diagnosis; because in the supported state, the vertical shaft sleeve 1 and the support shaft 14 can rotate relative to each other, during the consultation process, the parents can rotate and adjust the position of the support plate 4 and the cantilever 3 by pushing and pulling, that is, adjust the position of the pediatric patient to meet the comfort requirements of different users, and enable the doctor to examine the specific body parts of the pediatric patient more conveniently and quickly; in actual application, if there is no need to use the supporting mechanism to provide support for the pediatric patient, the support plate 4 and the cantilever 3 can be rotated to one side of the chair body, and the supporting mechanism will not constitute a significant obstacle to the normal use of the chair body; in addition, refer to Figure 1 , 2 As shown in , 7, when there is no need to use a supporting mechanism to provide support for pediatric patients, the cantilever 3 can also be rotated to a position extending forward and backward, and the cantilever 3 is rotated to adjust the supporting mechanism to a hand-held state. In this state, the support plate 4 is upright and located at the lower side of the cantilever 3, does not occupy additional space, and can prevent pediatric patients from sliding off one side of the seat plate 5. One end of the plug-in shaft 13 is inserted into the locking hole 10 so that the cantilever 3 cannot rotate horizontally, and the support plate 4 will rely on its own gravity to prevent the plug-in shaft 13 from rotating. At this time, the position of the cantilever 3 is relatively stable and can be used as an armrest, so that the pediatric chair is still more comfortable than an ordinary chair in the hand-held state.

[0037] See also Figure 1 , 4 As shown, in the above-mentioned pediatric chair, the backrest board 6 and the seat board 5 are provided with cushions 7, thereby further improving the comfort of the user during the medical consultation.

[0038] See also Figure 5 , 6 As shown, in the above-mentioned pediatric chair, the plug-in shaft 13 and the cantilever 3 are an integrated structure, and are made of the same metal material to ensure that both have sufficient strength to provide support for pediatric patients.

[0039] In the above-mentioned pediatric chair, the vertical sleeve 1 and the horizontal sleeve 2 in the corner sleeve can be connected by welding. A more preferred implementation is that the corner sleeve is made by bending a metal pipe sleeve, and the two sections formed by bending are the vertical sleeve 1 and the horizontal sleeve 2, respectively, thereby further ensuring the overall strength of the corner sleeve.

[0040] In the above-mentioned pediatric chair, the cantilever 3 and the support plate 4 are covered with a soft material layer (not shown) to improve the comfort of the pediatric patient.

[0041] See also Fig. 9 As shown, in the above-mentioned pediatric chair, the support plate 4 is made of a low-density composite material, and its main body adopts a hollow structure to reduce its own gravity while ensuring sufficient strength to provide support for pediatric patients, so as to reduce the load on components such as the cantilever 3, corner sleeves and support shaft 14.

[0042] See also Figure 1 , 2 As shown, in the above-mentioned pediatric chair, the seat board 5 and the backrest board 6 are an integrated structure.

[0043] See also Figure 3 , 4 As shown, in the above-mentioned pediatric chair, the edge of the support plate 4 is provided with a retaining edge 11 to prevent the pediatric patient from slipping.

[0044] See also Figure 7 , 8 As shown, in the above-mentioned pediatric chair, during the process of the guide pin 12 moving from the starting end to the end end of the guide groove 9, the plug-in shaft 13 rotates 270°; as a result, when the supporting mechanism is adjusted from the hand-held state to the supporting state, the support plate 4 just rotates 270° and is in a horizontal state. At this time, the support plate 4 cannot rotate downward, and the gravity of the support plate 4 can keep it in a horizontal state.

[0045] See also Fig.10 As shown, in the above-mentioned pediatric chair, a thrust bearing 15 is sleeved on the lower end of the support shaft 14, and the thrust bearing 15 abuts against the lower end of the vertical shaft sleeve 1 to bear the axial load (vertical load) generated by the vertical shaft sleeve 1.

[0046] See also Fig.11As shown, in the above-mentioned pediatric chair, the guide pin 12 and the plug-in shaft 13 can be connected in a variety of ways. In order to improve the connection strength of the above-mentioned two, the preferred method is that a mounting hole 16 is opened on the plug-in shaft 13, and the inner end of the guide pin 12 is arranged in the mounting hole 16 by threaded fit or interference fit. In the specific implementation, the plug-in shaft 13 is inserted into the horizontal shaft sleeve 2 in advance, and then the guide pin 12 and the mounting hole 16 are fixedly connected through the guide groove 9.

[0047] See also Figure 4 As shown, in the above-mentioned pediatric chair, when the supporting mechanism is in the supporting state and the cantilever 3 is located above the seat plate 5, the cantilever 3 is located in front of the support plate 4. Based on the above-mentioned positional relationship between the cantilever 3 and the support plate 4, the cantilever 3 can share more of the load generated by the pediatric patient and reduce the force on the support plate 4.

[0048] In the above-mentioned pediatric chair, the support shaft 14 is subjected to a large load, especially when supporting a pediatric patient. Therefore, the fixing firmness thereof has a high technical requirement. The present invention provides two preferred implementations, specifically:

[0049] First, see Fig.12 As shown, the lower end of the support shaft 14 is fixedly connected to a chair leg 8, and the upper end of the chair leg 8 is provided with a flange 18, which is fixedly connected to the seat plate 5 via a fixing bolt 17. The seat plate 5 is provided with a through hole 19, and the support shaft 14 extends to the top of the seat plate 5 through the through hole 19. By implementing in this way, it can be ensured that the support shaft 14 is fixedly fixed more firmly, and it is avoided to install a fixing component on the upper side of the seat plate 5, thereby ensuring that the upper side of the seat plate 5 is indirectly flat.

[0050] Second, see Fig.13 , 14As shown, the supporting mechanism includes a clamping seat, and the clamping seat is provided with an upper plate 21 and a lower plate 20 which are distributed up and down and parallel to each other. The upper plate 21 and the lower plate 20 are fixedly connected via the side plate 22. The gaps between the upper plate 21, the lower plate 20 and the side plate 22 can accommodate the corners of the seat plate 5. The support shaft 14 is fixed to the upper side of the upper plate 21. The lower plate 20 is provided with a U-shaped hole 24 which can accommodate the chair leg 8. The lower plate 20 is provided with a plurality of fastening bolts 23 for tightening the lower side of the seat plate 5. Based on the above structure, the clamping seat is placed on At the corner of the seat 5, tighten the fastening bolts 23 to tighten the lower side of the seat 5, and then the clamping seat is firmly connected to the seat 5, which can provide stable support for the support shaft 14; since the structure adopted by the clamping seat can be applicable to the seat 5 of most chairs, when the present invention is implemented, the chair body can adopt an existing ready-made chair without the need for special processing and manufacturing. It only needs to use the clamping seat to install the supporting mechanism on the existing chair, that is, to make the pediatric chair disclosed in the present invention, which makes the implementation of the present invention easier and the implementation cost lower.
