Description

Bedside elevation angle alarm device

Technical Field

The utility model relates to a sickbed, in particular to a bedside elevation angle alarm device.

Background

In order to facilitate the recovery of patients or various treatments during the period of lying in bed, the head of the sickbed in the hospital ward can be lifted. Raising the bed head can be beneficial to the respiration of patients and improve dyspnea; relieving abdominal wound tension and pain; can also reduce bleeding after head and neck surgery.

In clinical practice, the angular requirements for elevation of the bed are different due to the different actual conditions of different patients. For example, for patients with dyspnea caused by cardiopulmonary diseases, the patient needs to be lifted by 30 degrees to 45 degrees, so that the volume of the chest cavity can be enlarged, and the dyspnea can be improved; for patients lying in bed for a long time, the patient needs to be lifted by 15 degrees to 30 degrees, so that the shearing force of the patient can be reduced, and pressure sores are prevented from being generated.

When the head of a bed is actually lifted, because the naked eyes are difficult to directly judge whether the angle is in place, the angle is required to be measured through an angle measuring device, and accurate adjustment is achieved. The Chinese patent of CN217040561U announced by month 07 and 26 of 2022 discloses a medical bedside elevation angle monitoring and alarming device which is used for being fixed on the side wall of a medical sickbed and comprises a shell, a hanging body, a circuit board, a conducting strip, an alarming component and a power switch; the front surface of the shell is transparent or semitransparent, and angle scale marks distributed along the circumferential direction are arranged on the front surface of the shell; the suspension body is of a semicircular structure and is rotationally connected to the inside of the shell through a rotating shaft; two ends of the top of the suspension body are respectively provided with a metal ball, and the two metal balls are connected through a wire; the circuit board and the alarm assembly are both arranged on the inner side of the shell, the power switch is arranged on the outer side of the shell, and the power switch and the alarm assembly are both in circuit connection with the circuit board; the conducting strip and the circuit board are connected to the circuit board according to a preset circuit principle and circuit. The instrument has the advantages of simple working principle, simple fixing method, convenient disassembly, accurate measurement angle, easy observation and good stability.

In the above patent, the suspension body is used to rotate in the shell, and the angle is displayed by the weight of the suspension body, which belongs to the mechanical structure. However, the structure of the mechanical design is likely to be jammed during daily use, so that the device cannot be used, and therefore, a bedside angle prompting device which is not jammed, is easier to read angle values and better to control is needed.
