Description

Technical Field

[0001] The invention relates to the field of medical examination chairs, and in particular to an examination chair suitable for puncture treatment of pleural effusion. Background Art

[0002] Examination chairs, especially in medical environments such as hospitals and clinics, play an important role. They are designed to provide comfort and ensure that patients can remain relaxed while undergoing examinations or treatments, thereby helping medical staff to make more accurate diagnoses or treatments. Examination chairs usually have adjustable heights, angles and other features to accommodate the needs of different patients, while also better protecting the privacy of patients and reducing unnecessary exposure, thereby alleviating the psychological burden and embarrassment of patients. In addition, such chairs may also be equipped with cushions or other supports to increase comfort and relieve the discomfort caused by long periods of sitting.

[0003] When patients are examined in the hospital, they usually sit on an examination chair while medical staff perform acupuncture operations on the chest. During the acupuncture, the patient's head and arms lie on the pillow on one side of the examination chair to remain stable. Some patients have sensitive body parts and are at risk of toppling left or right or falling backwards due to stimulation during the acupuncture operation. At the same time, during the acupuncture operation, it is impossible to keep the body from shaking to avoid affecting the puncture effect. Therefore, an examination chair suitable for pleural effusion puncture treatment is needed. Summary of the invention

[0037] In this embodiment, a pair of protective plates 32 and a plastic clip 31 are fixedly connected to the lower surface of the storage box 13 .

[0038] A pair of protective plates 32 are provided to protect the sides of the patient's body. A plastic clip 31 is provided. The plastic clip 31 has toughness and can be bent and deformed. The punctured pipe is clamped and positioned by the pair of plastic clips 31.

[0039] As a preferred implementation scheme in this embodiment, a fixed plate 17 and an electric telescopic rod 18 are fixedly connected to the surface of the support frame 1, a ratchet 21 is fixedly connected to the surface of the second connecting shaft 16, a pawl 19 is fixedly connected to the output end of the electric telescopic rod 18, and a spring 20 is fixedly connected to the opposite surface of the pawl 19 and the fixed plate 17.

By providing the buffer pad 12, the armrest 5 can contact the surface of the buffer pad 12 when it is rotated, stored and reset, thereby achieving a buffering and protective effect.

[0043] The working principle of the present invention is: an examination chair suitable for puncture treatment of pleural effusion, after the patient sits on the seat 3, the arm is placed in the groove 10, and the head rests on the surface of the head pad 9. At this time, the pressure sensor 15 detects the gravity of the surface of the seat 3, and the first reduction motor 28 is started through the programming control of the PLC of the controller 7. The output end of the first reduction motor 28 drives the first bevel gear 24 to rotate, and the rotation of the first bevel gear 24 drives the second bevel gear 25 to rotate, and the rotation of the second bevel gear 25 drives the first connecting shaft 23 to rotate, and the rotation of the first connecting shaft 23 drives the chair 5 to rotate. During this process, the pawl 19 will not interfere with the rotation of the ratchet 21. When the backrest 5 rotates as a whole, it separates from the original contact state with the cushion 12 until it is in a vertical state. At this time, when the patient leans against the backrest 5, the pawl 19 prevents the ratchet 21, the second connecting shaft 16 and the backrest 5 from turning over as a whole. The storage box 13 ensures the stability of both sides of the patient so that the body will not tip over. This has the advantage of allowing the patient to sit on the seat 3 more comfortably and quickly. At this time, the first electric synchronous wheel 26 and the second electric synchronous wheel 30 are started to drive the synchronous belt 29 to rotate, so that the synchronous The belt 29 and the C-shaped plate 27 slide together on the inner wall of the backrest 5 to adjust its height. When the C-shaped plate 27 moves, it drives a pair of storage boxes 13 to move together. At this time, the second reduction motor 34 is started, and the output end of the second reduction motor 34 drives the third bevel gear 33 and the lower clamping plate 40 to rotate. The rotation of the third bevel gear 33 drives the fourth bevel gear 37 to rotate. The rotation of the fourth bevel gear 37 drives the fifth bevel gear 39 to rotate. The rotation of the fifth bevel gear 39 drives the rotating shaft 38 and the upper clamping plate 35 to rotate together. The upper clamping plate 35 and the lower clamping plate 40 are in contact with the patient's skin together to keep clamping Positioning can prevent the patient's body from moving, which is convenient for puncture operation. The drainage tube after puncture can be fixedly clamped in a pair of plastic clips 31 to keep it stable. When it is necessary to reset the recliner 5, the electric telescopic rod 18 is started to drive the pawl 19 and the ratchet 21 to be misaligned, and the spring 20 is stretched. At this time, the first reduction motor 28 is started to drive the recliner 5 to rotate and reset. The patient can get off the seat 3 quickly. With the above structure, the risk of the patient's body being stimulated during the acupuncture operation and tilting to the left or right or falling backward can be avoided. During the acupuncture operation, the body can be kept from shaking to avoid affecting the puncture effect.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
