Technical Field

[0001] The invention relates to the technical field of foot care, in particular to a height-adjustable foot care device. Background Art

[0002] Diabetes can cause many complications, affecting multiple organs, as well as blood vessels, nervous system and other aspects. Diabetic nephropathy is a very common cause of lower limb edema in diabetic patients. Diabetic foot swelling is caused by long-term high blood sugar in diabetic patients, which increases the viscosity of the blood. When the viscosity of the blood increases, it is easy to cause some vascular inflammation, which can easily cause blood vessel occlusion and edema in the feet.

[0003] Among the diabetes care devices, Chinese Patent Publication No.: CN111407636A discloses a foot care device for diabetic patients. The device adopts a swinging massage structure, which can drive the patient's feet to reciprocate while massaging the patient's feet, effectively promoting blood circulation in the patient's feet, thereby improving the effect of foot care treatment.

[0004] That is to say, the existing technology has solved the problem of foot edema by massage, so that the foot can absorb the care solution and promote blood circulation. However, the position of the foot may need to be adjusted during use. At this time, it is urgent to propose a foot care device that can be adjusted in height, and it is also necessary to solve the problem of squeezing the edematous part during the height adjustment process, which causes pain beyond massage. Summary of the invention

[0005] The object of the present invention is to provide a height-adjustable foot care device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, a height-adjustable foot care device is provided, which includes a basin with an opening at the top, through which the feet of diabetic patients enter the basin, and a height-adjusting plate group is provided in the basin. The basin is divided into a height-adjusting chamber, an intermediate chamber and a care chamber from bottom to top by the height-adjusting plate group, and the care chamber is height-adjusted by the downward flow of medicine filled between the three chambers.

[0007] As a further improvement of the technical solution, the height adjustment plate group includes a first plate body and a second plate body arranged at the bottom of the first plate body, and the first plate body and the second plate body both slide in the basin body, wherein:

[0008] A protruding column passing through the first plate body is arranged on the top of the second plate body, and a portion of the protruding column passing through the first plate body forms a protrusion for foot massage.

[0009] As a further improvement of the present technical solution, the first plate body and the second plate body are tightly fitted to the inner wall of the basin body, and after fitting, a care chamber is formed on the top of the first plate body, an intermediate chamber is formed between the first plate body and the second plate body, and a height adjustment chamber is formed at the bottom of the second plate body.

[0010] As a further improvement of the present technical solution, a valve for controlling the connection between the nursing chamber and the middle chamber is provided on the first plate body, and two first negative pressure pumps are provided on the second plate body, one of the first negative pressure pumps is used to output the medicine in the middle chamber to the height adjustment chamber, and the other first negative pressure pump outputs the medicine in the height adjustment chamber to the middle chamber.

[0011] As a further improvement of the technical solution, the initial water level in the nursing chamber is 10-15 cm.

[0012] As a further improvement of the present technical solution, a cover body is provided on the top of the basin body, and the outer contours of a set of opposite sides of the basin body and the cover body are recessed inward in a "V" shape to separate two independent cavities for placing the feet. The two cavities are connected to form a care chamber, and two foot entry grooves are provided on the cover body corresponding to the two cavities.

[0013] As a further improvement of the technical solution, a slot adapted to the contour of the top edge of the basin body is provided at the bottom of the cover body, and the cover body is plugged into the top edge of the basin body through the slot.

[0014] As a further improvement of the present technical solution, a fixing rod is arranged on the top edge of the basin body, and a limiting head is arranged on the top of the fixing rod. After the fixing rod passes through the through hole opened on the cover body, the limiting head expands outward to block the top surface of the cover body.

[0015] As a further improvement of the technical solution, an accommodating groove is provided on the outer side wall of the fixing rod close to the limiting head.

[0016] As a further improvement of the technical solution, the distance between the centers of the two foot entry grooves is 40-60 cm.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the height-adjustable foot care device for diabetes, the height-adjusting plate group is used to separate the basin body from bottom to top into a height-adjusting chamber, an intermediate chamber and a care chamber, and the care chamber is adjusted in height by the downward flow of medicine filled in the three chambers to adapt to the adjustment of the foot position.

[0019] 2. In the height-adjustable foot care device for diabetes, the protrusion passes through the part of the first plate body to form a protrusion for foot massage, so the top surface of the first plate body forms the surface where the protrusion is located, and in the process of raising the care chamber, a large distance difference is generated between the top surface of the first plate body and the protrusion, so as to prevent the top surface of the first plate body from squeezing the edema accumulated on the periphery during the process of raising the protrusion.

[0020] 3. In the height-adjustable foot care device for diabetes, when the medicine in the care chamber flows into the middle chamber, the flowing medicine will have a certain impact on the foot, thereby improving the comfort of the foot and relieving the pain caused by the protrusion to the foot in the initial stage.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present invention provides a height-adjustable foot care device, comprising a basin body 100 that is common in general care devices. The top of the basin body 100 has an opening, and the foot of a diabetic patient enters the basin body 100 through the opening. At this time, boiled water containing medicine (hereinafter referred to as medicine) can be added into the basin body 100. In order to facilitate the foot to absorb the medicine, a protrusion is usually provided in the basin body 100. At this time, the foot needs to fit on the surface where the protrusion is located, and then the foot is massaged by the protrusion. Sometimes, it is necessary to adjust the height of the surface where the protrusion is located to adapt to the position of the foot or to raise the entire basin body 100. However, if the diabetic patient is in a state of high blood sugar for a long time, the viscosity of the blood will increase. When the viscosity of the blood increases, it is easy to cause blood vessel occlusion, causing edema in the foot. When the edematous foot contacts the protrusion, it will accumulate around the protrusion. At this time, the surface where the protrusion is located is raised, and it is difficult for the foot to grasp the rising speed of the surface where the protrusion is located. In this way, the surface where the protrusion is located will squeeze the edematous part accumulated around the periphery, which undoubtedly brings pain to the patient beyond the pain caused by the protrusion massage.

[0039] First embodiment,

[0040] like Figure 3 As shown, a height adjustment plate group 300 is arranged in the basin body 100, and the height adjustment plate group 300 includes a first plate body 310 and a second plate body 320 arranged at the bottom of the first plate body 310. The first plate body 310 and the second plate body 320 both slide in the basin body 100. In addition, a protrusion 321 passing through the first plate body 310 is arranged on the top of the second plate body 320. The protrusion 321 passes through the part of the first plate body 310 to form a protrusion, and then the top surface of the first plate body 310 forms the surface where the protrusion is located. The difference between this embodiment and the ordinary height adjustment device is:

[0041] The height adjustment operation is completed by using the first plate 310 and the second plate 320 that form the protrusions. Figure 6 As shown, the first plate 310 and the second plate 320 are closely attached to the inner wall of the basin 100, and then a care chamber 100C is formed on the top of the first plate 310, an intermediate chamber 100B is formed between the first plate 310 and the second plate 320, and a height adjustment chamber 100A is formed at the bottom of the second plate 320, and there is no air in the height adjustment chamber 100A and the intermediate chamber 100B due to the filled medicine. Figure 3 A valve 311 for controlling the connection between the nursing chamber 100C and the intermediate chamber 100B is provided on the first plate body 310, and two first negative pressure pumps 322 are provided on the second plate body 320. One first negative pressure pump 322 is used to output the medicine in the intermediate chamber 100B to the height adjustment chamber 100A, and the other first negative pressure pump 322 is used to output the medicine in the height adjustment chamber 100A to the intermediate chamber 100B.

[0042] Working principle: The height-adjusting plate group 300 is used to separate the basin body 100 from bottom to top into a height-adjusting chamber 100A, an intermediate chamber 100B and a care chamber 100C, and the care chamber 100C is height-adjusted by the downward flow of medicine filled in the three chambers.

[0043] Figure 7-Figure 9 The embodiment of the height adjustment plate set 300 is disclosed. Figure 7 The first implementation mode of the present embodiment is disclosed, because the massage effect produced by the protrusion in the present embodiment is obtained by the active force exerted by the foot, that is, under normal use, the protrusion 321 will not protrude too much on the first plate 310, so as to use the top surface of the first plate 310 to limit the active downward pressure of the foot, and avoid excessive downward pressure of the foot to cause pain; when the protrusion needs to be raised, the first negative pressure pump 322 outputting to the height adjustment chamber 100A works, and during the output process, the second plate 320 will move up in the direction indicated by the arrow a, and the upwardly moved second plate 320 drives the protrusion 321 to move up synchronously, and the foot will also be raised with the upward movement of the protrusion 321 to adjust to a comfortable position for the patient, and at the same time, the first plate 310 will move down in the direction indicated by the arrow b, and at this time, a large distance difference will be generated between the top surface of the first plate 310 and the protrusion, so as to prevent the top surface of the first plate 310 from squeezing the edema accumulated on the periphery during the process of raising the protrusion;

[0044] Then, in order to return to normal use, Figure 8 In the embodiment of FIG. 1 , the valve 311 is opened. At this time, the medicine in the nursing chamber 100C flows to the middle chamber 100B through the valve 311, and then the medicine in the middle chamber 100B pushes the first plate 310 upward until the first plate 310 is restricted by the protrusion 321. At this time, the condition of normal use is restored, and the height of the entire protrusion is also increased. The liquid level in the nursing chamber 100C is adaptively decreased (because the medicine in the nursing chamber 100C enters the middle chamber 100B). The purpose is to prevent the medicine in the nursing chamber 100C from overflowing due to the increased height of the first plate 310.

[0045] In addition, when the medicine in the care chamber 100C flows into the middle chamber 100B, the flowing medicine will have a certain impact on the foot, thereby improving the comfort of the foot and alleviating the pain caused by the protrusion to the foot in the initial stage.

[0046] It should be noted that if the protrusion needs to be lowered, the first negative pressure pump 322 outputting to the middle chamber 100B will work and the valve 311 will be opened. Because the protrusion is in a descending state, there is no need to consider the impact on the foot, so the valve 311 is opened to allow the first plate 310 to move downward synchronously with the protrusion 321.

[0047] Fig. 9FIG. 2 shows a second implementation of the present embodiment. On the basis of the first implementation, it can be known that as the second plate 320 is raised, the medicine in the nursing chamber 100C will gradually decrease. It happens that diabetic patients cannot soak in water for a long time due to foot edema, so the process of the medicine in the nursing chamber 100C gradually decreasing can be utilized. When used specifically, after the foot enters the nursing chamber 100C, the first negative pressure pump 322 output to the height adjustment chamber 100A starts to work, and then the medicine volume in the middle chamber 100B is increased. That is, after all the medicine in the middle chamber 100B is output to the height adjustment chamber 100A, the operation stops for 5-10 seconds. During this process, the valve 311 is opened, and the middle chamber 100B is filled with medicine again for the next cycle. The foot can absorb the medicine within 5-10 seconds of stopping the operation. After 5-10 seconds, the first negative pressure pump 322 continues to work in the downward cycle. As the number of cycles increases, the medicine in the nursing chamber 100C will also decrease, thus solving the problem of long-term immersion of the foot.

[0048] Finally, when there is no medicine in the nursing chamber 100C, no medicine will be filled into the middle chamber 100B. At this time, the valve 311 is closed, and the first negative pressure pump 322 also stops working. The first plate 310 cannot move up because there is no medicine filled in the middle chamber 100B. At this time, the foot is supported by the protruding column 321 to perform the drainage operation.

[0049] It is further explained that if Figure 6 As shown, the initial water level height h in the care chamber 100C is controlled at 10-15cm, that is, it is just above the ankle, so as to reduce the depth of the feet soaked in the medicine as much as possible, while also ensuring the adjustable distance (from the above principle, it can be seen that the care device of the present invention uses the medicine in the care chamber 100C to achieve height adjustment).

[0050] Figure 1 , Figure 2 , Figure 4 and Figure 5 A second embodiment is disclosed,

[0051] like Figure 1 As shown, a cover body 200 is disposed on the top of the basin body 100, and the outer contours of a set of opposite sides of the basin body 100 and the cover body 200 are inwardly concave in a "V" shape to independently form two cavities for placing the feet, and the two cavities are connected to form the care chamber 100C in the first embodiment. Figure 4In addition, two foot entry grooves 200A are provided on the cover body 200 corresponding to the two cavities. The patient's foot enters the corresponding cavity through the foot entry grooves 200A, so that during the foot care process, the foot cannot be moved at will due to the restriction of the foot entry grooves 200A, and the foot entry grooves 200A are also the best foot entry position. Considering that different patients have different foot placement habits, after passing through the foot entry grooves 200A, the foot can move within the range restricted by the independent cavity, that is to say, the use of independent cavities can also prevent the feet from touching each other.

[0052] In addition, the cover 200 and the basin body 100 are detachable. Figure 4 As shown, a slot 200B adapted to the top edge contour of the basin body 100 is provided at the bottom of the cover body 200, and the disassembly between the slot 200B and the top edge of the basin body 100 is achieved by plugging the two together. After the cover body 200 is disassembled, it is convenient to inject medicine into the care chamber 100C, and the cover body 200 can also be removed for manual massage.

[0053] besides, Figure 2 In order to improve the plugging stability between the cover body 200 and the basin body 100, a fixing rod 210 is provided on the top edge of the basin body 100. Figure 5 As shown, after the cover body 200 is covered on the basin body 100, the fixing rod 210 will pass through the through hole opened on the cover body 200, and then the limiting head 211 extended outward from the top of the fixing rod 210 will block the top surface of the cover body 200 to improve the stability of the cover body 200 when inserted into the basin body 100.

[0054] It is worth mentioning that the limiting head 211 is a flexible structure. When the cover body 200 is removed, it is only necessary to lift the cover body 200 with force, and then the outer edge of the expanded limiting head 211 will shrink toward the top, so that the cover body 200 is separated from the contact restriction of the fixing rod 210. In addition, in order to facilitate the limiting head 211 to enter the through hole, a accommodating groove 210A is opened on the outer wall side wall of the fixing rod 210 close to the limiting head 211. After the through hole contacts the limiting head 211, the outer edge of the limiting head 211 will be squeezed by the inner wall of the through hole and will be received in the accommodating groove 210A, so as to facilitate the fixing rod 210 to pass through the through hole. After passing through, the outer edge of the limiting head 211 will expand to block the top surface of the cover body 200.

[0055] It is further explained that Figure 6 It is shown that the distance d between the centers of the two foot entry grooves 200A is controlled at 40-60 cm to accommodate the distance of the patient's feet when sitting down, thereby improving the comfort during nursing.

[0056] Fig.10 A third embodiment is disclosed,

[0057] This embodiment improves the protruding column 321 on the basis of the first embodiment. The difference from the first embodiment is that the interior of the solid protruding column 321 is hollowed out to form a hollow structure with an opening at the top, and a first negative pressure pump 3211 is arranged at the bottom of the protruding column 321. During foot care, the first negative pressure pump 3211 works to give the medicine in the middle chamber 100B a negative pressure to impact the sole of the foot, so as to utilize the impact force of the medicine to improve the massage effect of the protrusion, and the valve 311 is in an open state at this time, so that the medicine entering the care chamber 100C flows back to the middle chamber 100B through the valve 311. In this process, due to the time difference of the reflux or the difference in the reflux amount, the first plate body 310 will float up and down. The floating first plate body 310 will drive the medicine in the care chamber 100C to surge, and the surging water will hit the foot again, thereby improving the comfort of the foot during massage to relieve the pain caused by the massage.

[0058] In addition, a flange 3212 is provided on the top outer wall of the protruding column 321 . The protruding column 321 uses the flange 3212 to restrict the upward movement of the first plate 310 during the whole process.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
