Description

Technical Field

[0001] This utility model relates to an upright bed, and more particularly to an upright bed with protection, belonging to the field of rehabilitation training equipment technology. Background Technology

[0002] Upright beds are commonly used in rehabilitation medicine. For patients who have lost the ability to walk due to stroke, spinal cord injury, or traumatic brain injury, upright beds can be used for rehabilitation training to help them overcome postural hypocalcemia, muscle atrophy, and other conditions, thus aiding in the recovery of walking ability. Several technical solutions for upright beds have been disclosed in Chinese patent applications, such as CN201920395388.8 (an adjustable upper section upright bed), CN202022774997.X (an upright bed that can be quickly lowered), and CN 202323161219.3 (a base frame device that can be used with existing upright beds). For ease of movement, existing upright bed equipment typically includes braked casters or uses a caster lifting mechanism to achieve both moving and fixed states. For example, CN... The base frame device disclosed in 202323161219.3 can be used for both vertical fixation and movement of existing upright beds; it has two states. CN202022774997.X discloses an upright bed that can be quickly lowered, which uses this device. Of course, there are other mechanisms that can also perform the above functions. In actual use, when the patient is in the upright position, they may not be visible from behind. Medical staff may assume that there is no one on the upright bed and move the bed using casters. Because the overall center of gravity of the bed with the patient is high in this position, the possibility of tipping over during movement is greatly increased. Tipping over can cause unpredictable injuries to the patient, which must be strictly avoided in rehabilitation training machinery. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in existing upright training beds and to provide an upright bed with protection.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A protective upright bed includes a base frame device, which includes a second bent rod, a long connecting rod, and a third straight rod. A vertical frame is fixedly connected to the base frame device. The upright bed body is hinged to the vertical frame near its lower part via a horizontal hinge shaft. The actuating end of an electric push rod is hinged to the upright bed body, and the body is hinged to the base frame device. Two foot pedals and a chest circumference limiting plate are installed on the upright bed body. The electric push rod is connected to a controller. A bed board is fixedly installed on the upright bed body. A limit switch is fixedly installed on the base frame device near the long connecting rod. The trigger rod of the limit switch faces upward. During the process of driving the third straight rod to lift the base frame device, the long connecting rod presses against the trigger rod, triggering the limit switch to conduct. A pressure switch is installed on the foot pedal. When the patient's foot is in the upright training state, it presses against the pressure switch to conduct. The pressure switch and the limit switch are connected in series and then connected to the reverse power control circuit of the electric push rod.

[0005] Furthermore, pressure switches are installed on both foot pedals, and the pressure switches on the two foot pedals are connected in parallel and then in series with limit switches.

[0006] Furthermore, a pressure-type power switch is fixedly installed on the upright bed board. The pressure-type power switch is connected in series in the power circuit of the warning light. When the pressure-type power switch is pressed, the warning light is powered on and illuminates.

[0007] The positive and beneficial technical effects of this utility model are as follows: When a patient is training in an upright position on this upright bed, two pressure switches will be activated. If someone steps on the third crossbar, the limit switch will be activated, thus activating the reversing power circuit of the electric push rod motor. This drives the electric push rod motor to reverse, causing the push rod to retract and turning the upright bed into a horizontal position. The rotation of the electric push rod motor to turn the bed into a horizontal position also serves as a reminder that a patient is undergoing upright training, prompting personnel to operate in a timely manner. Staff can use the controller to level the upright bed before moving it, avoiding the risk of tipping over caused by moving the bed while the patient is training in an upright position, thus protecting the patient from injury. When the pressure switch is pressed when a patient is using the bed, the warning light will illuminate, alerting relevant personnel that a patient is on the bed, thus serving as a warning and protection function. The protective components on this upright bed are very simple and readily available, making it particularly suitable for modifying existing upright beds to enhance protection.

[0011] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0012] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: upright bed frame; 2: base frame device; 23: long connecting rod; 24: second curved rod; 25: third straight rod; 3: vertical frame; 4: electric push rod; 5: foot pedal; 6: chest circumference limiting plate; 7: limit switch; 8: pressure switch; 9: pressure power switch;

[0013] In this application, the base frame device adopts the base frame device disclosed in CN 202323161219.3. For ease of comparison, the long connecting rod shown in 23, the second bent rod shown in 24, and the third straight rod shown in 25 are all the same as the component names corresponding to the reference numerals in the drawings of CN 202323161219.3.

[0014] A protective upright bed includes a base frame device 2, which comprises a second bent rod 24, a long connecting rod 23, and a third straight rod 24. A vertical frame 30 is fixedly connected to the base frame device. The upright bed body 1 is hinged to the vertical frame near its lower part via a horizontal hinge shaft. The actuating end of an electric push rod 4 is hinged to the upright bed body, and the machine body is hinged to the base frame device. Two foot pedals 6 and a chest-limiting plate 6 are installed on the upright bed body. The electric push rod is connected to a controller for control. A bed board 10 is fixedly installed on the upright bed body. All of the above are current... Some upright beds are equipped with a limit switch 7 fixedly installed on the base frame near the long connecting rod. The trigger rod of the limit switch faces upward. When the third straight rod 24 is driven to lift the base frame, the long connecting rod 3 presses against the trigger rod, triggering the limit switch to conduct. A pressure switch 8 is installed on the foot pedal. When the patient's foot is in the upright training state, it presses against the pressure switch to conduct. The pressure switch and the limit switch are connected in series and then connected to the reverse power control circuit of the electric push rod. This circuit is very simple and can be easily implemented by relevant technicians. More specifically, pressure switches are installed on both foot pedals. The pressure switches on the two foot pedals are connected in parallel and then in series with the limit switch. In this way, as long as one pressure switch has a signal, single-path conduction is guaranteed, preventing situations where a patient's foot is weak and cannot trigger the pressure switch.

[0015] A pressure-type power switch is fixedly installed on the upright bed board. This switch is connected in series with the power circuit of the warning light. When the pressure switch is pressed, the warning light illuminates. Pressure-type power switches are existing and very common. In this invention, the pressure switch is located on the back of the bed board, ensuring reliable pressure response. Alternatively, it can be preferably installed at the corresponding position on the buttocks. The warning light alerts relevant personnel that a patient is performing upright training on the bed.

[0016] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
