Abstract

The invention discloses a rotary chair for radiation medical treatment, which comprises a chair back and a chair surface with a fixing device, and is characterized in that: the included angle between the chair back and the chair seat is larger than 90 degrees. One form is: the chair surface is provided with a cushion block with an inclined plane. In another form: the angle between the chair back and the chair seat is adjusted through the chair seat lifting mechanism. According to the invention, through the chair surface arranged obliquely, the two legs of a patient keep a downward inclined state when the patient is subjected to radiotherapy, so that the interference between the two legs and a ray head when the pelvic cavity and other position focus radiotherapy is carried out is avoided. In addition, the chair surface lifting device is arranged to drive the chair surface to lift, so that the sitting posture of the patient can be switched between flat sitting and inclined sitting. In order to ensure the stability of the patient in the inclined sitting state, a fixing device or a fixing hole can be arranged on the chair surface to position the body of the patient.

Description

swivel chair for radiology

technical field

The invention belongs to the technical field of medical equipment, in particular to a rotating chair for radiation medicine.

Background technique

In the equipment for particle radiation therapy of cancer, the prone position is now commonly used. The lying position is to lie on the bed, and the patient is fixed on the bed. In such a position, it is difficult for the patient to do a 360 ^o turn. In order to achieve 360 ^o multi-angle beam therapy, only by changing the incident angle of the beam. In order to realize 360 ^o multi-angle radiation beam therapy in the treatment equipment with fixed angle radiation beams, there are also sitting postures now. The patient is fixed on the chair, and the chair is installed on the rotating motor, which can rotate at a 360 ^° angle. So as to realize the treatment of the patient's body in ^360o multi-angle. However, because the legs in the sitting posture interfere with the radiation beam therapy head, it is difficult for the radiation beam to irradiate the pelvic lesion. In order to solve this problem, the present invention is a new device that enables the patient to utilize the existing chair to realize the treatment of pelvic lesions.

Contents of the invention

The purpose of the present invention is to provide a rotary chair for radiology which can avoid interference of legs during treatment, in view of the defects of conventional rotary chairs for radiology.

In order to achieve the above object, the present invention adopts the following technical solutions:

A swivel chair for radiation medicine, comprising a chair back and a chair surface with a fixing device, characterized in that the angle between the chair back and the chair surface is greater than 90 degrees.

One form: the chair surface is provided with cushion blocks with slopes.

Another form: the angles of the chair back and the seat surface are adjustable.

It is further characterized in that: a chair lifting mechanism is provided under the chair surface.

The chair lifting mechanism is arranged at the front or rear edge of the chair.

Further: the chair lifting mechanism is a hydraulic lifting mechanism, or a screw lifting mechanism.

Preferably: a long hole or a round hole for positioning the legs is provided in the middle of the chair surface.

The swivel chair is arranged on a combination of a swivel mechanism, a pitch control mechanism and a lifting mechanism.

The rotating mechanism is driven by a rotating motor, and the lifting mechanism is driven by an electric cylinder.

In the present invention, the inclined chair surface enables the patient to keep his legs tilted downward during radiotherapy, thereby avoiding the interference between the legs and the ray head during radiotherapy of pelvic and other lesions. In addition, by setting the chair surface lifting device to drive the chair surface lifting, the patient's sitting posture can be switched between flat sitting and oblique sitting. In order to ensure the stability of the patient in the reclining state, a fixing device or a fixing hole can be provided on the chair surface to position the patient's body.

detailed description

A swivel chair for radiation medicine, comprising a chair back 1 and a chair surface 2 with a fixing device, the angle between the chair back 1 and the chair surface 2 is greater than 90 degrees, so that the patient's legs keep tilting downward during radiotherapy state.

As shown in Figure 1, a kind of form: by being provided with cushion block 3 with inclined-plane above the chair surface of chair surface 2 levels, this inclined-plane has just become the chair surface of new and chair back angle greater than 90 °.

As shown in Fig. 2, another form: adjust the angle between the chair back 1 and the chair surface 2 through the chair surface lifting mechanism 4, so that the patient's sitting posture can be switched between flat sitting and oblique sitting.

The chair surface elevating mechanism 4 drives the rear edge of the chair surface 2 to move upward, so that the patient's legs are tilted downward to prevent the interference of the leg radiation head. The chair surface lifting mechanism 4 can also be arranged at the front position of the chair surface 2 . During use, the chair surface lifting mechanism 4 descends to make the patient's legs tilt downward.

As shown in FIG. 2 , the chair surface lifting mechanism 4 is arranged at the front edge and the rear edge of the seat surface 2 at the same time. The inclination of the chair surface is formed by the fact that the rear edge of the chair surface 2 rises higher than the front edge, so that the patient's legs are tilted downward.

The above-mentioned chair surface lifting mechanism 4 is a hydraulic lifting mechanism, or a screw rod lifting mechanism.

Preferably: in order to keep the patient in a stable position when the chair surface 2 is tilted, a long hole 21 for positioning the legs is provided in the middle of the chair surface 2, or fixed holes 22 are provided on both sides of the long hole 21, through the long hole 21 Or the fixing hole 22 can be equipped with a fixing device to fix the patient's legs.

In order to realize the treatment of the patient body at multiple angles of 360 ^° , the rotating chair is set on a combination of a rotating mechanism 5 , a pitch control mechanism 7 and a lifting mechanism 6 . Through the rotation mechanism 5, the pitch control mechanism 7 and the lifting mechanism 6, the rotary chair is driven to rotate, lift and pitch to adapt to the position of the radiation beam treatment head. The rotating mechanism 6 is driven by a rotating motor, and the lifting mechanism 6 is driven by an electric cylinder.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description are only the principles of the present invention.
