Description

Technical Field

[0001] This invention belongs to the field of medical devices, and specifically relates to a stretcher-type weighing bed and its usage method. Background Technology

[0002] Critically ill patients require numerous life-sustaining tubes and should not be moved extensively, or at least not moved at all. Current weighing techniques involve significant movement (CN204219245U); they are also unstable during weighing, and the presence of these tubes makes movement or turning during transport inconvenient, causing considerable inconvenience for medical staff. Furthermore, some critically ill patients require a semi-sitting or semi-recumbent position during transport. For example, some critically ill patients are not fully conscious and require the front half of the bed to be raised for feeding, as gravity helps them eat. For such patients, current technology makes folding the bed for feeding inconvenient, especially when considering weighing (CN 216365586 U). Therefore, given these technical problems, there is an urgent need for a weighing bed or method that allows for minimal movement during weighing and is easily raised. Summary of the Invention

[0003] To address the technical problems encountered in medical weighing mentioned above, this invention designs a stretcher-type weighing bed, the specific details of which are as follows:

[0018] Four electronic scales (9.4) can be displayed simultaneously on a single monitor (not shown in the diagram), similar to a weighbridge.

[0019] The bed has guardrails at both the front and back ends, which are not shown in the diagram.

[0020] The lifting bed section is self-powered, allowing the patient to control the raising of the front section themselves.

[0021] Protective sleeves or similar devices are installed on the outside of the hydraulic cylinder to protect people outside from being trapped.

[0022] The specific operating method of the weighing bed is as follows: Shake the rocker arm 11 so that its front end enters the support hole 8.3; control the four hydraulic cylinders 9 to simultaneously raise the hydraulic rod 9.3; the hydraulic rod 9.3 drives the support rod 8 upward, and the support rod 8 causes the pull pieces 7 connected at both ends to tilt, and the two pull pieces 7 respectively drive the connected pull plug 5 and pull block 6 to slide inward within the insertion tube 3.2; when the pull plug 5 and pull block 6 slide to one end of the pull rail 3.5 and can no longer move, the pull rod 5.1 inserts into the opposite end. Insert the tube 3.2; at this time, the two half stretchers 3 can no longer be folded in half; as the hydraulic rod 9.3 continues to rise, the two half stretchers 3 are removed from the fixed bed 1; the electronic scale 9.4 displays the weighing data; when not weighing, shake the rocker arm 11 so that its front end is removed from the support hole 8.3, and then raise the hydraulic cylinder 9 as a guardrail for the weighing bed; the lifting bed 2 has its own lifting power, and when one end of it rises, the half stretcher 3 on the same side of its support rises upward. At this time, the connection between the pull member 7 and the support member 8 on the same side rotates.

[0023] The beneficial technical effects of this invention are as follows:

[0024] The innovative aspects of this application will now be further elaborated in conjunction with its technical features and effects:

[0025] 1. This application includes a pull rod, a support rod, a pull insert, and a pull block. The pull insert and pull block slide within a pull rail. Two half-stretchers are connected by hinges. After the lifting hydraulic cylinder is activated, it moves the support rod upwards. The pull rod pulls the pull insert within the pull rail, causing the pull rod to insert into the intubation tube of the other half-stretcher, preventing the two half-stretchers from bending further by the hinges. This allows the stretchers to support the patient's weight. When the pull rod can no longer slide, the stretcher is lifted off the fixed bed by four hydraulic cylinders. An electronic scale displays the weighing data.

[0026] 2. The handrail designed in this application is connected to the support hole of the hydraulic cylinder via a rocker arm. Rotating the rocker arm causes its front portion to extend out of the support hole of the handrail. The hydraulic cylinder then lifts the handrail. The connection between the hydraulic cylinder and the handrail can function as a standalone bed rail when not in use.

[0027] 3. The lifting bed is connected to the fixed bed via a fixed shaft, allowing one end of the lifting bed to be raised. A stretcher cloth is installed on the stretcher. The lifting bed is supported by power; the two half-stretchers are connected by hinges. The lifting bed causes the mattress on the bed and one side of the half-stretcher to tilt. Based on the technical effect described in technical effect 2, patients can more easily feed themselves. Based on technical effect 1, when weighing the stretcher, the stretcher can rise straight up; when feeding or when the upper body needs to be lifted, the middle of the stretcher can be bent, i.e., the two half-stretchers can be bent via hinges. During this process, the patient's movement or activity is minimized, ensuring a stable medical condition. Attached Figure Description
