Description

Technical Field

[0001] The utility model relates to a dialysis bed, in particular to a hemodialysis bed with weight measurement function. Background Art

[0002] Dialysis is a separation and purification technology that separates small molecules from biomacromolecules by the principle that small molecules diffuse into water (or buffer) through a semipermeable membrane. Dialysis therapy is a treatment method that allows components (solutes or water) in body fluids to be excreted from the body through a semipermeable membrane. It can generally be divided into hemodialysis and peritoneal dialysis.

[0003] The weight of dialysis patients will decrease during the dialysis process. To prevent unexpected situations during the dialysis process, medical staff need to carefully compare the weight change before and after dialysis to adjust the dialysis rate. Medical staff usually judge the weight change of patients based on the dehydration amount on the dialysis machine.

[0004] When judging the patient's weight change based on the amount of dehydration, it is inaccurate to judge solely based on the amount of dehydration because some solutes are also excreted from the body during the dialysis process. When too much solute is excreted from the patient's body and it is not displayed on the dialyzer, the patient will suffer from malnutrition or even shock. Utility Model Content

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0041] Please refer to Figures 1 to 8 , as an embodiment of the present invention, the hemodialysis bed with weight measurement includes a bed frame 1 and a first bed board 2 provided on the bed frame 1; a second bed board 201 is rotatably installed on the first bed board 2;

[0042] A plurality of induction mechanisms are provided on the bed frame 1. When the weight on the first bed board 2 changes, the induction mechanism can drive the first bed board 2 to approach or move away from the bed frame 1;

[0043] A reaction mechanism is provided on the bed frame 1, and the reaction mechanism can feedback the weight change amount when the induction mechanism acts;

[0044] A rotation mechanism is further provided on the bed frame 1, and the rotation mechanism can drive the second bed board 201 to rotate.

[0045] In this embodiment, the patient lies on the first bed board 2 and the second bed board 201 during dialysis.

[0046] When the patient lies completely on the first bed board 2, the induction mechanism will drive the first bed board 2 to approach the bed frame 1. At this time, the reaction mechanism will make a reaction to record the patient's weight before dialysis.

[0047] Since the patient's weight will decrease during dialysis, and the dialysis machine will display the dehydrated amount, which is the vague weight loss amount.

[0048] As the patient's weight decreases, the induction mechanism will drive the first bed board 2 to gradually move away from the bed frame 1, and the reaction mechanism will follow and make a feedback change. By comparing with the weight before dialysis, an accurate weight change value can be obtained and compared with the data on the dialysis machine.

[0049] Medical staff can drive the second bed board 201 to rotate through the rotation mechanism, so as to adjust the angle between the second bed board 201 and the first bed board 2, so that the patient is in the best dialysis lying position, making dialysis more smooth and increasing the patient's comfort.

[0050] Through the mutual cooperation of the induction mechanism and the reaction mechanism, the weight change value of the patient can be timely feedback to the medical staff to facilitate the medical staff to provide the best medical care for the patient.

[0051] As a further solution of the present utility model, the sensing mechanism includes a telescopic sleeve 101 fixedly installed on the bed frame 1, and a telescopic column 202 fixedly connected to the first bed board 2 is slidably fitted in the telescopic sleeve 101; a telescopic spring 203 fixedly connected to the telescopic column 202 is fixedly installed in the telescopic sleeve 101.

[0052] In this embodiment, when the patient lies completely on the first bed board 2, the first bed board 2 will be squeezed under the action of the patient's own weight, causing the first bed board 2 to move downward, thereby driving the telescopic column 202 to slide inward in the telescopic sleeve 101 and compressing the telescopic spring 203. Therefore, the compression amount of the telescopic spring 203 is determined by the patient's weight.

[0053] When the patient's weight decreases, the force transmitted to the telescopic spring 203 will also decrease accordingly, so the compression amount will become smaller, thereby driving the telescopic column 202 to slide outward in the telescopic sleeve 101, so that the first bed board 2 moves away from the bed frame 1.

[0054] Since the compression amount of the telescopic spring 203 changes in time with the weight, the sensing mechanism can sense the change in the patient's weight in time without any lag, so as to facilitate the medical staff to judge the patient's health status.

[0055] As a further solution of the present utility model, the reaction mechanism includes a hydraulic rod 3 fixedly installed on the first bed board 2, and a piston 301 is fixedly installed on the hydraulic rod 3; a hydraulic sleeve 4 slidably fitted with the hydraulic rod 3 and the piston 301 is fixedly installed on the bed frame 1; an observation sleeve 5 is fixedly installed on the bed frame 1; the observation sleeve 5 is fixedly connected to the hydraulic sleeve 4 through a conduit 6.

[0056] In this embodiment, there is hydraulic fluid in the hydraulic sleeve 4, the conduit 6 and the observation sleeve 5. When the first bed board 2 approaches the bed frame 1, it will drive the hydraulic rod 3 to slide inward in the hydraulic sleeve 4, thereby driving the piston 301 to slide inward in the hydraulic sleeve 4. The hydraulic fluid in the hydraulic sleeve 4 will be squeezed by the piston 301 and flow into the observation sleeve 5 along the conduit 6, thereby increasing the content of the hydraulic fluid in the observation sleeve 5 and raising the hydraulic fluid level in the observation sleeve 5.

[0057] When the first bed board 2 moves away from the bed frame 1, the first bed board 2 will drive the hydraulic rod 3 to slide outward in the hydraulic sleeve 4, thereby driving the piston 301 to slide outward in the hydraulic sleeve 4. At this time, the piston 301 will suck the hydraulic fluid in the observation sleeve 5 into the hydraulic sleeve 4 along the conduit 6, thereby lowering the hydraulic fluid level in the observation sleeve 5.

[0058] By comparing the height difference of the hydraulic fluid level in the observation sleeve 5, the change in the patient's weight can be obtained. Moreover, since the height of the hydraulic fluid level changes with the position of the first bed board 2, the height of the hydraulic fluid level in the observation sleeve 5 can promptly feedback the change value of the patient's weight.

[0059] As a further solution of the present utility model, the rotation mechanism includes a lead screw 7 rotatably installed on the first bed board 2; an internally threaded sleeve 8 is threadedly connected to the lead screw 7; a connecting rod 9 is rotatably installed on the internally threaded sleeve 8, and one end of the connecting rod 9 away from the internally threaded sleeve 8 is rotatably installed on the second bed board 201.

[0060] In this embodiment, when the lead screw 7 rotates, the internally threaded sleeve 8 will slide on the lead screw 7 due to the threaded fit with the lead screw 7, thereby driving the connecting rod 9 to rotate on the internally threaded sleeve 8, thus changing the included angle between the two. When the included angle between the connecting rod 9 and the internally threaded sleeve 8 increases, the included angle between the connecting rod 9 and the second bed board 201 also increases, thereby pushing the second bed board 201 to rotate towards the first bed board 2, making the included angle between the two smaller.

[0061] When the included angle between the connecting rod 9 and the internally threaded sleeve 8 decreases, the included angle between the connecting rod 9 and the second bed board 201 also decreases, thereby pushing the second bed board 201 to rotate away from the first bed board 2, making the included angle between the two larger.

[0062] Medical staff can drive the second bed board 201 to rotate through the rotation mechanism, thereby adjusting the included angle between the second bed board 201 and the first bed board 2, so that the patient is in the best dialysis lying position, making dialysis smoother and increasing the patient's comfort. And since it is driven by rotating the lead screw 7, when the lead screw 7 stops rotating, the included angle between the first bed board 2 and the second bed board 201 will remain unchanged.

[0063] As a further solution of the present utility model, a plurality of guardrails 11 are rotatably installed on the bed frame 1, and the plurality of guardrails 11 are all rotatably installed on the armrest 10, and a self-locking mechanism is connected to one of the guardrails 11.

[0064] In this embodiment, by applying an upward force to the armrest 10, the armrest 10 can be driven to move upward, thereby increasing the included angle between the guardrail 11 and the armrest 10 and increasing the included angle between the guardrail 11 and the bed frame 1. And the armrest 10 always remains horizontal with the bed frame 1 during the movement process.

[0065] When the guardrail 11 is perpendicular to the bed frame 1, the guardrail 11 will cooperate with the self-locking mechanism, so that the included angle between the guardrail 11 and the bed frame 1 remains unchanged.

[0066] As a further solution of the present utility model, the self-locking mechanism includes a rotating block 13 rotatably mounted on the bed frame 1. A chute 1301 is formed in the rotating block 13, and a wedge block 1302 is slidably fitted in the chute 1301. A limiting spring 1303 fixedly connected to the wedge block 1302 is fixedly installed in the chute 1301. A reset spring 12 fixedly connected to the bed frame 1 is fixedly installed on the rotating block 13.

[0067] The self-locking mechanism further includes a fitting groove 1101 formed in the guardrail 11 connected to the self-locking mechanism.

[0068] In this embodiment, when the guardrail 11 tends to be perpendicular to the bed frame 1, the guardrail 11 will contact the wedge block 1302 and continuously squeeze the wedge block 1302 to slide inward in the chute 1301, and the limiting spring 1303 will be compressed. When the wedge block 1302 enters the fitting groove 1101, the guardrail 11 will be disengaged from the wedge block 1302, and under the elastic force of the limiting spring 1303, the wedge block 1302 will completely enter the fitting groove 1101.

[0069] One side of the wedge block 1302 facing the bed frame 1 is a flat surface, and its back surface is an inclined surface. When the wedge block 1302 completely enters the fitting groove 1101, the flat surface of the wedge block 1302 will cooperate with the fitting groove 1101 to limit the position of the guardrail 11 so as to keep the included angle between the guardrail 11 and the bed frame 1 unchanged.

[0070] When it is necessary to fold the guardrail 11 and the armrest 10, by applying a downward force to the rotating block 13, the rotating block 13 rotates on the bed frame 1, so that the chute 1301 is away from the guardrail 11. At this time, the inclined surface of the wedge block 1302 will cooperate with the fitting groove 1101, so that the wedge block 1302 slides in the chute 1301, so that the wedge block 1302 is disengaged from the contact and cooperation with the fitting groove 1101 to release the restriction on the guardrail 11, thereby facilitating the folding of the guardrail 11.

[0071] When the rotating block 13 rotates, the reset spring 12 will be compressed. After the restriction on the guardrail 11 is released, the force applied to the rotating block 13 is released, and the elastic force of the reset spring 12 will reset the rotating block 13.

[0072] As a further solution of the present utility model, a sleeve cover is threadedly connected to the observation sleeve 5, and a plurality of pressure relief holes are formed in the sleeve cover; and a plurality of groups of protrusions are fixedly installed on the edge of the sleeve cover.

[0073] In this embodiment, the pressure relief holes can release the pressure in the observation sleeve 5 when the height of the hydraulic fluid level in the observation sleeve 5 changes. The setting of the protrusions facilitates the installation of the sleeve cover.

[0074] The above embodiments are illustrative rather than restrictive. Therefore, all technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are encompassed within the present invention.
