Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and particularly relates to a control device for a physician's seat. Background Art

[0002] As is well known, when physicians perform examination or treatment operations for a long time, they are prone to physical fatigue. If the fatigue of the limbs cannot be relieved, the operation will become unstable, directly affecting the results of treatment or examination.

[0003] Currently, for a physician's seat, it includes a seat, armrests, and a walking wheel assembly. In order to meet the needs of physicians of different body types for work or rest, generally, the seat and armrests of a physician's seat can be adjusted in terms of lifting or / and flipping. However, due to the adjustment of multiple parts, the existing control devices separately set the corresponding control modules, and the physician's hand needs to move repeatedly between the control modules for adjustment, resulting in cumbersome operation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved control device for a physician's seat.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A control device for a physician's seat, which is used for the adjustment of the seat and armrests of a physician's seat. The control device includes a control seat having a plurality of contact points, and an adjustment component movably connected to the control seat. A trigger portion matching the contact points is formed on the adjustment component. The plurality of contact points are distributed on the movement path of the trigger portion and are respectively connected to the seat and the armrests. During adjustment, the control component is moved to drive the trigger portion to trigger the corresponding contact points.

[0007] Preferably, the plurality of contact points are divided into a seat contact point group for adjusting the seat and an armrest contact point group for adjusting the armrests. The control component includes a seat adjustment module cooperating with the seat contact point group and an armrest adjustment module cooperating with the armrest adjustment contact point group. The trigger portion includes a seat trigger portion located on the seat adjustment module and an armrest trigger portion located on the armrest adjustment module. With this setting, the adjustment functions of the armrests and the seat are separated, facilitating the operation of the physician and avoiding confusion.

[0008] Specifically, the seat adjustment module is rotatably connected to the control seat through a first pivot, and the contact points in the seat contact point group are distributed on the rotation path of the seat trigger portion; the armrest adjustment module is rotatably connected to the control seat through a second pivot, and the contact points in the armrest contact point group are distributed on the rotation path of the armrest trigger portion. With this setting, the adjustment is performed by rotation, and the operation is simple and labor-saving.

[0009] Further, a seat control surface and an armrest control surface are formed on the control base. The seat contact group is disposed within the seat control surface, and the armrest contact group is disposed within the armrest control surface. The centerlines of the first pivot shaft and the second pivot shaft are respectively parallel or coincident with the seat control surface and the armrest control surface. Moreover, multiple contacts within the seat contact group are distributed on the seat control surface on both sides of the first pivot shaft; multiple contacts within the armrest contact group are distributed on the armrest control surface on both sides of the second pivot shaft. With such a setting, the two adjustment modules can be more closely attached to the control base, thus effectively reducing the volume of the control device; at the same time, two-way adjustment can be achieved, that is, by adjusting the adjustment module to the left or right, the lifting and / or flipping adjustment of the seat and the armrest can be realized.

[0010] Preferably, the control base includes a first base body and a second base body distributed from bottom to top. The seat control surface is formed on the side surface of the first base body, and the armrest control surface is formed on the top surface of the second base body. Moreover, the centerlines of the side surface of the first base body, the top surface of the second base body, the first pivot shaft, and the second pivot shaft in the horizontal plane are coincident. With such a setting, the two control surfaces are not on the same horizontal plane, further ensuring the avoidance of confusion in the adjustment functions of the seat and the armrest; at the same time, the symmetric structure is more stable, facilitating operations such as assembly and subsequent disassembly and maintenance.

[0011] Specifically, the centerline of the seat trigger portion coincides with the centerline of the first pivot shaft. The seat trigger portion respectively forms a first contact surface for triggering the corresponding contacts on both sides of its own centerline; the centerline of the armrest trigger portion coincides with the centerline of the second pivot shaft. The armrest trigger portion respectively forms a second contact surface for triggering the corresponding contacts on both sides of its own centerline.

[0012] Preferably, the seat adjustment module includes a first module body. The seat trigger portion is sleeved and fixedly connected to the outer periphery of the first pivot shaft, and the first module body is fixedly connected to the top of the seat trigger portion. With such a setting, it is convenient for the doctor to toggle and adjust.

[0013] Preferably, the armrest adjustment module includes a second module body and pedals. The second module body is sleeved and fixedly connected to the outer periphery of the second pivot shaft. The armrest trigger portion is fixedly connected to the top of the second module body. There are two pedals and they are integrally formed on the opposite sides of the armrest trigger portion. With such a setting, the doctor can use his feet to step on for adjusting the armrest, thus freeing both hands and facilitating the doctor to rest or focus on the operation.

[0014] Specifically, a U-shape with an opening facing the first module body is formed between the two pedals and the armrest trigger portion. The first module body extends obliquely upward from the top of the seat trigger portion and passes through the opening of the U-shape. With such a setting, it can remind the doctor to toggle and adjust the seat adjustment module within the range of the opening of the U-shape, avoiding damage to components caused by excessive adjustment.

[0015] In addition, the control device further includes elastic members disposed on the movement paths of the seat trigger portion and the armrest trigger portion, wherein the elastic members include two first elastic members respectively disposed on the seat control surfaces on both sides of the first pivot, and two second elastic members respectively disposed on the armrest control surfaces on both sides of the second pivot. With this arrangement, after each adjustment is completed, the movement of the seat and the armrest can be stopped simply by releasing, and the two adjustment modules can automatically reset, facilitating the next adjustment.

[0016] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0017] In the present invention, the contacts for controlling the seat and the armrest are integrated on the control seat. By simply moving the adjustment member, the adjustment of the seat and the armrest can be achieved. The operation is simple, facilitating the physician to quickly adjust the seat posture during rest or work. At the same time, the structure is simple and the implementation is convenient.

[0032] As Figures 1 to 4 shown, the control device of the doctor's seat in this embodiment is used for adjusting the seat and armrest of the doctor's seat, and the control device includes a control seat 1 and an adjustment component 2.

[0033] Specifically, the control seat 1 is provided with a seat contact group composed of a seat rising contact 1a and a seat descending contact 1b for connecting the seat, and an armrest contact group composed of an armrest rising contact 2a and a seat descending contact 1b for connecting the armrest.

[0034] The adjustment component 2 includes a seat adjustment module 21 rotatably connected to the control seat 1 through a first pivot s1 and cooperating with the seat contact group, and an armrest adjustment module 22 rotatably connected to the control seat 1 through a second pivot s2 and cooperating with the armrest adjustment contact group. With such a setting, the adjustment is carried out by rotation, which is simple and labor-saving; at the same time, the adjustment functions of the armrest and the seat are separated, which is convenient for the doctor to operate and avoids confusion.

[0035] At the same time, the seat adjustment module 21 is provided with a seat trigger part a, and the seat rising contact 1a and the seat descending contact 1b are respectively located on the movement path of the seat trigger part a and match the seat trigger part a; the armrest adjustment module 22 is provided with an armrest trigger part b, and the armrest rising contact 2a and the armrest descending contact 2b are respectively located on the movement path of the armrest trigger part b and match the armrest trigger part b.

[0036] In this example, the control seat 1 includes a first seat body 11 and a second seat body 12. The front side surface of the first seat body 11 extends vertically and forms a seat control surface m1, and the top surface of the second seat body 12 extends obliquely backward and upward from the front side edge and forms an armrest control surface m2. The seat rising contact 1a and the seat descending contact 1b are arranged side by side at intervals on the seat control surface m1, and the armrest rising contact 2a and the seat descending contact 1b are arranged side by side at intervals on the armrest control surface m2. With such a setting, the two control surfaces are not on the same horizontal plane, further ensuring that the adjustment functions of the seat and the armrest are not confused.

[0037] For convenience of implementation, the centerlines of the first pivot s1 and the second pivot s2 are respectively arranged parallel to the seat control surface m1 and the armrest control surface m2. The first pivot s1 protrudes upward from the top of the first seat body 11. The seat rising contact 1a and the seat descending contact 1b are respectively located on the seat control surface m1 on both sides of the first pivot s1. The armrest rising contact 2a and the armrest descending contact 2b are respectively located on the armrest control surface m2 on both sides of the second pivot s2. With such an arrangement, the two adjustment modules can fit the control seat better, thus effectively reducing the volume of the control device. At the same time, two-way adjustment can be achieved, that is, by adjusting the adjustment module to the left or right, the lifting and / or flipping adjustment of the seat and the armrest can be realized.

[0038] Combined Figure 4 As shown, the centerlines of the orthographic projections of the side surface of the first seat body 11, the top surface of the second seat body 12, the first pivot s1, and the second pivot s2 on the horizontal plane coincide. With such an arrangement, the symmetrical structure is more stable, which is convenient for operations such as assembly and later disassembly and maintenance.

The seat trigger part a is sleeved and fixedly connected to the outer periphery of the first pivot s1, and the centerline of the seat trigger part a coincides with the centerline of the first pivot s1. The seat trigger part a respectively forms a first contact surface a1 for triggering the corresponding contacts on both sides of its own centerline. The first module body 211 is fixedly connected to the top of the seat trigger part a. With such an arrangement, it is convenient for the doctor to toggle and adjust.

[0040] At the same time, a guide bushing s10 is also provided on the outer periphery of the first pivot s1. A rotating part a2 sleeved on the first pivot s1 and having a notch matching the guide bushing s1 is formed on the seat trigger part a.

[0041] In this example, the armrest adjustment module 22 includes a second module body 222 and a pedal 223.

[0042] Specifically, two grooves c1 are arranged side by side at intervals along the inclined direction on the armrest control surface m2. The second pivot s2 passes through the two grooves c1. Two parts of the second module body 222 are respectively inserted into the two grooves c1 and fixedly connected to the second pivot s2. The armrest trigger part b is fixedly connected to the top of the second module body 222. The centerline of the armrest trigger part b coincides with the centerline of the second pivot s2. The armrest trigger part b respectively forms a second contact surface (not shown in the figure but easy to imagine) for triggering the corresponding contacts on the bottom surfaces on both sides of its own centerline. There are two pedals 223 and they are integrally formed on the opposite sides of the armrest trigger part b. With such an arrangement, the doctor can use his feet to step on for the adjustment of the armrest, thus liberating both hands and facilitating the doctor to rest or concentrate on the operation.

[0043] At the same time, the two pedals 223 and the armrest trigger part b form a U-shape with an opening toward the first module body 211, wherein the first module body 211 extends obliquely upward from the top of the seat trigger part a and passes through the U-shaped opening, and a slide groove c2 matching the armrest trigger part b is formed on the bottom surface of the end of the first module body 211 away from the seat trigger part a. This arrangement can remind the doctor to adjust the seat adjustment module within the U-shaped opening range to avoid damage to parts caused by excessive adjustment.

[0044] In addition, the control device of this embodiment also includes an elastic component 3 arranged on the movement path of the seat trigger part a and the armrest trigger part b, wherein the elastic component 3 includes two first elastic members 31 respectively arranged on the seat control surface m1 on both sides of the first pivot s1, and two second elastic members 32 respectively arranged on the armrest control surface m2 on both sides of the second pivot s2. With this arrangement, after each adjustment is completed, the movement of the seat and the armrest can be stopped by simply releasing them, and the two adjustment modules can be automatically reset, which is convenient for the next adjustment.

[0045] In summary, the advantages of this embodiment are as follows:

[0046] 1. The contacts for controlling the seat and armrests are integrated on the control seat. The seat and armrests can be adjusted by simply moving the adjustment components. The operation is simple, which is convenient for doctors to quickly adjust the seat posture when resting or working. At the same time, the structure is simple and easy to implement;

[0047] 2. Adjustment is done by rotation, which is simple and labor-saving. At the same time, the adjustment functions of the armrest and the seat are separated to facilitate the doctor's operation and avoid confusion.

[0048] 3. The two adjustment modules can be made to fit the control seat more closely, thereby effectively reducing the volume of the control device. At the same time, two-way adjustment can be achieved, that is, by adjusting the adjustment module to the left or right, the seat and armrests can be raised or lowered or / and flipped.
