Description

Technical Field

[0001] The invention relates to a patient chair, in particular to a patient chair for back puncture surgery. Background Art

[0002] Back puncture surgery (thoracic puncture surgery, lumbar puncture surgery, spinal puncture surgery, etc.) lacks a special operating chair, and different doctors have different surgical methods. There are three main surgical methods: The first surgical method is that the patient sits on the chair with the back of an ordinary chair. The second surgical method is that the patient sits on the bedside, and the patient's relatives hold the patient in front of the patient or act as a support for the patient to hold or support. The third method is to let the patient lie on the table with a sheet or pillow on the table.

[0003] The first surgical method is that the patient sits on the chair backwards while holding the back of an ordinary chair. In this form, the patient needs to communicate with the doctor constantly to adjust the sitting posture and the arch angle of the waist and back, which takes a lot of energy and time for the doctor and the patient. At the same time, because the patient's hands, chest and abdomen are not supported, the sitting posture during the operation will be uncomfortable and painful. The second surgical method is that the patient sits on the bedside of the hospital bed, and the patient's relatives hold the patient in front of the patient or act as a support for the patient to hold or hold. This method also requires a lot of communication between the patient and the doctor to adjust the posture and the arch angle of the waist and back, and if the relatives do not hold it firmly, it will cause the patient to be injured. This method has a greater safety hazard and risk of medical accidents. The third method is to let the patient lie on the table with a mat or pillow on the table. This method has the same problem as the first method. The doctor and the patient need a lot of time to adjust the posture. And because there is an extra table, it is more troublesome to adjust the position.

[0004] The three main surgical methods currently have disadvantages. The first surgical method is that the patient sits on the chair backwards while holding the back of an ordinary chair. In this form, the patient needs to communicate with the doctor constantly to adjust the sitting posture and the arch angle of the waist and back, which takes a lot of energy and time for the doctor and the patient. In addition, the chair has no casters, which makes it inconvenient for the doctor to move the patient. At the same time, the patient's sitting posture during the operation will be uncomfortable and painful because the hands, chest and abdomen are not supported.

[0005] The second surgical method is that the patient sits on the bedside, and the patient's relatives hold the patient in front of the patient or act as a support for the patient to hold or hold. This method also requires a lot of communication between the patient and the doctor to adjust the posture and the arch angle of the waist and back. If the relatives do not hold the patient firmly, the patient may fall and get injured. This method has greater safety hazards and medical malpractice risks.

[0006] The third method is to let the patient lie prone on a table with a sheet or pillow on it. This method has the same problem as the first method, and the doctor and the patient need a lot of time to adjust their posture.

[0052] Specifically, Figure 6 and Figure 7 As shown, the chair back comprises a mounting shell 18, a soft outer layer 7 and a support frame 21, the chair back lifting assembly is fixedly mounted on the support frame 21, the mounting shell 18 is sleeved outside the chair back lifting assembly, and the mounting shell 18 and the soft outer layer 7 are driven to move up and down by the chair back lifting assembly, the soft outer layer 7 is mounted outside the mounting shell 18, and the soft outer layer 7 can be a wrapping layer filled with soft material, which is sleeved outside the mounting shell 18 and moves up and down with the mounting shell 18, while the frame is in a fixed mounting state and will not move up and down;

[0053] Among them, the bottom of the support frame 21 is hinged to the seat back inclination adjustment component, and the two sides of the support frame 21 are hinged to the two sides of the mounting frame 6. After the seat back inclination adjustment component is pushed out, the seat back can be retracted so that the angle between the seat back and the horizontal plane gradually decreases. When the seat back inclination adjustment component is retracted, the seat back can be continuously opened and the angle between it and the horizontal plane becomes larger.

[0054] like Figure 6 and Figure 7 As shown, the seat back lifting assembly includes:

[0055] The seat back lifting drive member 24 is fixedly mounted on the support frame 21 . In this embodiment, the seat back lifting drive member 24 is a motor push rod.

[0056] A movable lifting plate 20, wherein a guide slider 19 is disposed on one side of the movable lifting plate 20 facing the support frame 21, and the guide slider 19 is slidably assembled with the support frame 21;

[0057] A connecting cross bar 23, both sides of which are fixedly connected to the movable lifting plate 20, and an output end of the chair back lifting drive 24 is fixedly connected to the connecting cross bar 23;

[0058] A first hinged ear 22 is installed on the connecting cross bar 23, and the output end of the chair back lifting drive member 24 is hingedly connected to the first hinged ear 22. When the chair back needs to be raised, the chair back lifting drive member 24 is controlled to be lifted up, and the connecting cross bar 23 is used to drive the movable lifting plates 20 on both sides to slide upward relative to the supporting frame 21. When the movable lifting plates 20 rise, they can rise with the entire installation shell 18 and the soft outer layer 7, and the descent can be achieved by retracting the chair back lifting drive member 24.

[0059] like Figure 2 As shown, a second articulated ear 13 is provided at the bottom of the support frame 21, and the driving shaft 14 of the seat back inclination adjustment component is hinged to the second articulated ear 13. Third articulated ears 12 are provided on both sides of the support frame 21, and fourth articulated ears 11 are provided on both sides of the mounting frame 6. The third articulated ear 12 is articulated to the fourth articulated ear 11. When the seat back inclination adjustment component is actuated, the above-mentioned articulated structure can be used to control the inclination of the seat back relative to the seat cushion 5.

[0060] In this embodiment, if Figure 3 As shown, the seat back tilt adjustment component includes a seat back tilt driving member 15, the driving shaft 14 is arranged at the output end of the seat back tilt driving member 15, and the seat back tilt driving member 15 is hingedly connected to the seat cushion 5 at one end away from the driving shaft 14. When the seat back tilt driving member 15 is actuated, the second hinge ear 13 can be pushed to adjust the seat back tilt. In this embodiment, the seat back tilt driving member can be a cylinder or an electric push rod.

[0061] In order to better stabilize the patient, when the patient sits on the cushion 5, the patient can stretch both hands toward the back. A gripping portion 10 is fixedly installed at the bottom of the movable lifting plate 20, and the gripping portion 10 can be grasped by both hands for convenient support.

[0062] In this embodiment, the seat cushion lifting assembly adopts a seat cushion 5 lifting motor, and armrests 16 are respectively provided on both sides of the chair back. During surgery, the patient can lean his hands on the armrests 16. A control panel 17 is provided on one of the armrests 16, and the patient can use one of his hands to make various posture adjustments. The top of the chair back has an arc-shaped drag portion 9, and the patient's chin can be dragged by the arc-shaped drag portion 9. The bottom of the chassis 1 is also provided with a walking roller 3 with a brake.

[0063] In addition, the present invention can not only control the inflation of the airbags manually, by voice or gestures, but also has an automatic adjustment function. The three airbags or motors on the chair back are respectively equipped with pressure sensors, which can automatically adjust the puncture position according to the patient's weight, stature and body shape information. The pressure sensor will monitor the contact pressure between the patient's body and the chair back in real time. When the appropriate pressure value is reached, the system will determine whether the patient's chest cavity has expanded to a suitable surgical posture. At the same time, through the feedback function of the pressure sensor, it can prevent excessive pressure from causing discomfort or injury to the patient, ensuring the safety of the patient during the operation. The automatic adjustment function greatly improves the efficiency of the operation and reduces the time for repeated communication between doctors and patients.

[0064] Specifically, airbags or motors are installed at the top, middle and bottom of the chair back, and multiple sensors (such as pressure sensors) are used to sense the status of the airbags and the contact between the patient and the chair back. The signal from the pressure sensor is transmitted to the control unit, which adjusts the inflation or contraction of each airbag accordingly to ensure automatic adjustment of the patient's posture. This function can feedback the current status through the display screen to show whether the appropriate body position has been achieved.

[0065] The present invention can also add a metering function for the degree of airbag inflation. The gas flow rate in the airbag is monitored and recorded in real time through a gas flow sensor to determine the degree of airbag inflation. The data is transmitted to a display device or indicator light, and the doctor is prompted with lights or numerical values ​​to know the current inflation status of the airbag, thereby helping the doctor to better understand the airbag adjustment status, which not only improves the doctor's control accuracy of the device, but also can further optimize the patient's posture adjustment.

[0066] Specifically, a gas flow sensor is installed in the airbag inflation assembly, and the sensor is connected to the control panel 17 or the display device through a line to monitor and feedback the inflation of the airbag in real time. The doctor can accurately control the inflation degree of the airbag according to the prompts of the display or indicator light to ensure that the patient's posture is in the best state.

[0067] In addition to button and rocker control, the present invention can also be controlled by foot switch, remote control, voice control and other methods. Doctors can choose a more convenient control method to adjust various functions of the patient chair, such as adjusting the height of the chair back, the tilt angle, the inflation degree of the airbag, etc. This diversified control method not only improves the usability of the device, but also allows doctors to operate the device more flexibly in different surgical environments.

[0068] In addition to conventional buttons and joysticks, the control panel 17 also integrates a foot switch, an infrared receiving module and a voice control module. The infrared receiving module matches the remote control and remotely controls the various functions of the device by transmitting and receiving signals. The voice control module can recognize specific voice commands to control the device to meet different needs during the operation.

[0069] The present invention can also add a "common position" memory function, which can record the doctor's commonly used surgical postures, including parameters such as chair back angle, chair back height, and seat cushion height. During the surgical preparation process, the doctor can long press the "common position" button to memorize and save the current chair back height, tilt angle and other parameters. After that, just press the "common position" button lightly, and the system will automatically adjust the device to the parameters in memory, reducing the debugging time before the operation and further improving the operating efficiency.

[0070] Specifically, a "common position" button is provided on the control panel 17, which is connected to the control system to record the current relevant posture parameters of the chair back and seat cushion. The system has a built-in memory that can store multiple common position parameters and call them through one-button operation when the doctor needs them, automatically adjusting the device to a predetermined position. The memory settings can be set and called through the control panel 17 or remote control.

[0071] like Figure 8 As shown, a bearing can be set at the connection position between the seat cushion lifting assembly and the seat cushion, so that the seat cushion can complete a circular rotation relative to the seat cushion lifting assembly and be adjusted to any position. A hand screw can be set at the rotating connection position to complete the locking positioning.

[0072] The beneficial effects of the present invention are as follows: the present invention can accurately adjust the patient's posture angle, especially the degree of chest arching, according to different surgical requirements (such as thoracocentesis, lumbar puncture, etc.) through the posture adjustment component arranged on the chair back, thereby ensuring that the patient can maintain a suitable posture during the operation and reducing the discomfort caused by long-term surgery. At the same time, the adjustment function of the seat cushion and the chair back inclination enables patients of different body shapes to be effectively supported, further improving comfort;

[0073] The invention uses the electric lifting and tilting adjustment functions to keep the patient's body position stably at the optimal puncture angle set by the doctor, avoiding surgical errors caused by improper or unstable patient postures. In addition, the armrests and hand rests on the chair back provide additional support for the patient, reducing the risk of posture changes during surgery, and further improving the safety of surgery.

[0074] The electric adjustment components of the chair back and the seat cushion of the present invention are controlled by a control panel, so that the doctor can quickly adjust the patient's posture without frequent manual intervention, which reduces the time for adjusting the patient's position and improves the efficiency of surgical preparation and operation. At the same time, the up and down lifting and tilt adjustment functions of the chair back can help the doctor flexibly adjust the patient's position during the operation to find the best surgical angle, and the control mode can be controlled by the patient or the doctor, which is more flexible.

[0075] The present invention is not only suitable for back puncture surgery, but can also be widely used in various surgical operations such as epidural anesthesia and spinal puncture. It has multifunctional adaptability, further expanding its clinical application scope.

[0076] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
