Description

Technical Field

[0001] The utility model relates to the technical field of wheelchairs, in particular to a wheelchair type weight measuring instrument. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes through a dialyzer composed of hollow fibers. The blood and electrolyte solutions with similar concentrations to the body are exchanged through diffusion, ultrafiltration, adsorption and convection inside and outside the hollow fibers to remove metabolic wastes, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] At present, the human scales and health scales seen on the market only allow people to stand on them to weigh themselves when they need to. For this special group of patients, they need to measure their body weight every morning during the dialysis treatment interval to understand the body water growth, and they need to accurately measure their body weight before and after the dialysis treatment to understand the body water growth, so as to provide a reference for the setting of dialysis dehydration dose. Generally, patients can measure directly by standing on the electronic scale, but for some patients in wheelchairs, they need to get off the wheelchair to measure, and then transfer back to the wheelchair after completing the weighing; this transfer process inevitably has safety hazards, and some patients cannot even leave the wheelchair at all. Therefore, how to measure the weight of these patients in wheelchairs is very critical to their recovery.

[0004] Hemodialysis patients need to measure their weight before and after treatment. However, after long-term hemodialysis treatment, their physical tolerance decreases significantly, and some patients may not be able to complete standing measurements. In order to avoid secondary injuries to patients, a wheelchair weight measuring instrument is required.

[0005] The existing technology has the following problems:

[0006] In actual use of existing wheelchair-type measuring instruments, the foot pedals of existing wheelchairs are usually fixed structures and the height cannot be adjusted. When a patient sits in the wheelchair and places his feet on the foot pedals, if the foot pedals are too high, the patient's hip flexion angle is too large, and more weight is added to the ischial tuberosity, which can easily cause pressure sores in this area, causing discomfort to the patient and inconvenience in use.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1-4 As shown, the utility model provides a wheelchair-type weight measuring instrument, including a frame 1, handrail frames 2 are symmetrically fixedly installed on both sides of the front end of the frame 1, moving wheels 3 are symmetrically fixedly installed on both sides of the front and rear ends of the lower end of the frame 1, a back plate 4 is fixedly installed on the inner side of the rear end of the frame 1, an adjustment mechanism 5 is installed on the lower side of the front end of the frame 1, a weighing assembly 6 is installed above the adjustment mechanism 5, and a display screen 7 is fixedly installed on the rear end of the back plate 4.

[0026] The display screen 7 is electrically connected to the weighing sensor 63 .

[0027] Through the adjustment mechanism 5, the knob 53 can drive the mounting seat 54 to rotate through the damping fixed shaft 52, and when the footrest 59 is in a tilted state, the leg rest 56 can support the patient's legs, and the telescopic rod 58 can adjust the height of the footrest 59, which can improve the patient's comfort and prevent the patient from bending his hip too much, which causes more weight to be added to the ischial tuberosity, thereby avoiding pressure sores at the ischial tuberosity. It is easy to use, and the patient's weight can be weighed by a weighing assembly 6 using a plurality of weighing sensors 63, and the measured data can be transmitted to the display screen 7 for easy observation, so that the patient's weight can be weighed without leaving the wheelchair.

[0028] like Figure 3 As shown, the adjustment mechanism 5 includes a fixed seat 51, the outer side of the fixed seat 51 is fixedly connected to the connection between the frame 1 and the armrest frame 2, the middle of the fixed seat 51 is rotatably connected with a damping fixed shaft 52, the top of the damping fixed shaft 52 is fixedly installed with a knob 53, the bottom end of the damping fixed shaft 52 is fixedly installed with a mounting seat 54, the inner middle of the mounting seat 54 is fixedly installed with a connecting plate 55, the top of the connecting plate 55 is fixedly installed with a leg rest 56, the front side of the leg rest 56 is fixedly installed with a latex pad 57, the lower end of the mounting seat 54 is fixedly installed with a telescopic rod 58, and the lower end of the telescopic rod 58 is fixedly connected with a foot pedal 59.

[0029] The fixing seat 51 and the mounting seat 54 are both circular.

[0030] The lower end of the telescopic rod 58 is fixedly connected to the rear side of the upper end of the footrest 59 .

[0031] The latex pad 57 can improve the comfort of the patient's legs.

[0032] like Figure 4 As shown, the weighing assembly 6 includes a seat plate 61, the outer end surface of the seat plate 61 is fixedly connected to the lower side of the frame 1, a mounting groove 62 is opened on the upper side of the seat plate 61, a plurality of groups of weighing sensors 63 are fixedly installed inside the mounting groove 62, and a cushion 64 is installed on the upper end of the seat plate 61.

[0033] The upper end of the seat plate 61 is fixedly connected to the lower end of the seat cushion 64 .

[0036] The working principle of this wheelchair-type weight measuring instrument is described in detail below.

[0037] like Figure 1-4 As shown, when the wheelchair-type weight measuring instrument is in use, when the patient sits on the wheelchair, the patient's feet are placed on the footrest 59, and the knob 53 can be rotated at the same time, so that the knob 53 drives the damping fixed shaft 52 to rotate in the fixing seat 51, and at the same time, the damping fixed shaft 52 drives the mounting seat 54 to rotate, so that the mounting plate drives the footrest 59 to rotate through the telescopic rod 58, so that the footrest 59 can be in an inclined state, and at the same time, when the mounting seat 54 rotates, it will drive the leg support 56 to move synchronously through the connecting plate 55, so that the angle of the leg support 56 can be adjusted, so that the leg support 56 can fit the patient's legs, so that the patient's legs can be adjusted. The footrest 59 can be used for support to prevent the patient's feet from slipping off the footrest 59, and is easy to use. The length of the telescopic rod 58 can also be adjusted, and then the height of the footrest 59 can be adjusted, thereby improving the patient's comfort. It can also prevent the patient from bending his hip too much, which causes more weight to be added to the ischial tuberosity, thereby avoiding pressure sores at the ischial tuberosity, and is convenient for patients to use. When the patient needs to be weighed, the weighing sensor 63 can be started, so that multiple groups of weighing sensors 63 can measure the patient's weight, and the measured data can be transmitted to the display screen 7 for easy viewing, and the patient does not need to stand on the scale for weighing.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
