The preferred embodiments in the following description are only examples, and other obvious modifications may occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the invention.

Please refer to Figures 1-2. The present utility model provides a technical solution: a side support seat, including:

The chair base 100 is provided with adjacent operating sides 101 and the human body's back-facing sides 102;

The bottom of the elastic support member 200 is connected to the operating side 101 . The top surface of the elastic support member 200 is provided with an arm bypass portion 203 . The elastic support member 200 is inclined toward the outside of the seat 100 .

In this lateral support seat, a user sits and stands above the seat 100. The user can lean on the inclined elastic support member 200 when the user is leaning sideways. The inclined elastic support member 200 can provide a better position for the elbow of the user when the user is leaning sideways. The range of movement is large, and the user's body can move within the elastic range of the elastic support 200, thereby reducing the load on the user's waist muscles.

Specifically, the reason for the heavy load on the waist muscles of users of existing seats is that users of existing seats can only support their elbows above the fixed armrests and have limited movement, causing the user's waist to remain in the same position for a long time. Fixed position.

In this new type of seat, when the user is supporting sideways with the elastic support 200, the elastic support 200 can match the user's tilted arm, and the user's arms and elbows can move on the contact surface of the elastic support 200, and the elastic support The member 200 is elastically deformed by the user's leaning action, so that the user's waist can maintain a relatively comfortable range of motion when leaning sideways, thus reducing the load on the user's waist muscles.

It should be noted that the side support seat can be used in the examination work of sonographers. Ultrasound examination is a common and highly used examination in clinical practice. The workload of sonographers is relatively large, and the work of sonographers is very difficult. Because it is often necessary to maintain a sideways posture to the right and forward when operating instruments and examination content, and the chairs used in daily work cannot provide corresponding waist support for the sonographer, causing the sonographer's waist to be damaged by maintaining the same posture for a long time. Muscle and bone injuries, the application of the side support seat can avoid the above problems, and the examiner can bypass the top surface of the elastic support 200 to operate the ultrasound probe to operate the patient.

In order to facilitate the elastic support member 200 to support the examiner's arm when operating the ultrasonic probe, and to prevent the elastic support member 200 from partially compressing the examiner's arm and causing discomfort, further, the center of the arm bypass portion 203 is concave downward in an arc shape.

The traditional seat armrest 600 is only suitable for elbow support, and its set height is low, which cannot meet the support needs of the user when working sideways.
