Description

Inverted chair with armrest

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a handstand chair with handrail.

Background

The incidence rate of urinary calculus in China is 8.4%, namely 12000 million patients exist in the whole country. The incidence rate of biliary nodules is 5.6 percent, namely 8000 ten thousand patients exist in the whole country. There are 2 billion lithiasis patients in total, with 25% of patients requiring hospitalization. Since lithiasis is associated with constitution, living environment, living habits, working properties and dietary preferences, which are difficult to change, the recurrence rate of lithiasis is high and gradually increases with the passage of time after treatment. In the United states, the 5-10 year recurrence rate of urinary stones is about 50%; and China exceeds 80 percent. The recurrence of urinary calculus in China is mostly caused 2-3 years after calculus removal and other treatments, the cumulative total recurrence rate in 5 years is 50%, and the recurrence rate in 9 years is more than 70%. How to treat calculus and prevent recurrence is a serious problem.

The stones of the human body gradually grow from small to large, and for example, kidney stones can be microscopically small crystals in urine examination. These small crystals converge into small stones. The small stones can be discharged out of the body by running and jumping. However, the kidney has three groups of approximately ten netbag-shaped renal calyxes from the upper part to the middle part, and the renal calyxes share one renal pelvis outlet, wherein 3-4 renal calyx outlets of the lower group face upwards, like a bottle with an upward opening, and stones are attracted to the bottom of the bottle by gravity and are difficult to move upwards by themselves. If the small calculus can not be discharged for a long time, the small calculus further grows into a large calculus which is difficult to discharge, renal colic and hydronephrosis can be caused, and even renal function is lost.

For the treatment of the kidney stones, inverted movement or operation is generally adopted, and the operation has great harm to the human body; the hand-held handstand exercise is difficult to be held for a long time for most people, and the position of the handstand exercise cannot be the best angle for discharging the calculus out of the renal pelvis. Stones may also be difficult to detach from the infrarenal calyx due to binding or adhesions, requiring the application of external forces to assist in removing stones through vibration.

The external shock wave lithotripsy is preferably adopted when clinical stones are treated in hospitals, and after the external shock wave lithotripsy, the crushed stones are automatically discharged out of the body through urine of patients. However, many crushed stones are not easy to be discharged due to the above reasons, and often need weeks or even three months to be discharged completely, so that not only is the psychological burden or possible pain of a patient increased, but also the residual stones are easy to relapse. In order to accelerate the calculus removing process, doctors often recommend that patients drink more water after surgery and take calculus removing measures such as jumping, flapping, running or handstand. In order to solve the problem of accelerating the discharge of the crushed stone from the urinary tract, a lithotripter is manufactured, the structure and the principle of the lithotripter are mainly that a patient lies on a bed with a changeable plane angle, a doctor holds a mechanical device with a vibration function to vibrate the body position of the patient so as to help the lithotripter to be discharged, and a special B-ultrasonic machine is matched to observe the lithotripter to be discharged. However, such devices are extremely expensive and are only affordable to hospitals, and patients must regularly express a specific amount of time to go to the hospital for treatment, which is time consuming and expensive. Therefore, the utility model of the handstand chair with the armrests is urgently needed to facilitate the treatment and prevention of the calculus of the patient and reduce the cost.
