[0029] The beneficial effects of the utility model are:

[0030] First, in the specific implementation, the leg support described in the present application is made of memory foam material, which has good flexibility and can automatically deform according to the thickness of the patient's legs to adapt to and support the patient's legs, so that the part of the patient's legs in contact with it has good force uniformity and good support comfort. At the same time, the patient's legs are placed in the leg clamping groove and are fastened by the calf fastener and the thigh fastener, so that it is not easy to tip over and fall, so that the present application has good reliability and safety in use. The patient's heel falls into the heel clamping groove and is fixed, so that the patient's foot is not easy to tip over, so that the placement is stable and it is not easy to pull the meridians of the knee joint surgery site due to tipping, so that the patient's knee joint surgery site is not easy to cause complications.

[0031] The second point is that different patients have different calf lengths, which makes the front and back positions of their knee joint surgical sites different. Therefore, in the present application, when the hollow groove is formed into a long groove shape arranged along the front and back direction, it can be adapted to the suspended support of different patients' knee joint surgical sites with different front and back positions, making the present application highly adaptable.

[0032] Third, by setting up a plurality of the left pipe grooves, it is easy to select one of them to lead out to the left and fasten the drainage line that may be led out from the patient's knee joint surgery site, making the present application convenient to use. By setting up a plurality of the right pipe grooves, it is easy to select one of them to lead out to the right and fasten the drainage line that may be led out from the patient's knee joint surgery site, making the present application more convenient to use.

[0033] Fourthly, when applying the present application, for a patient who has undergone knee replacement surgery, after he lies flat on the bed, the present application is placed on the bed to lift the patient's legs after the knee replacement surgery, so that the heel of the patient after the knee replacement surgery falls into the heel clamping groove, and the surgical part of the knee joint of the patient after the knee replacement surgery falls on the hollow groove and is suspended in the air. After that, the male Velcro A can be pulled to make its appropriate position stick to the appropriate position of the female Velcro A, and the male Velcro B can be pulled to make its appropriate position stick to the appropriate position of the female Velcro B. In this way, the patient's legs can be easily fastened to quickly fix them.

[0034] Fifth, since the calf tightening piece includes the elastic band A with a certain elasticity, and the thigh tightening piece includes the elastic band B with a certain elasticity, the elastic band A and the elastic band B work together so that the patient's legs will not be rigidly tightened, but can move slightly within a certain range, so that it is not easy to tighten the patient's legs and cause the skin of the legs to be damaged and ulcerated. In other words, through this optimized design, the calf tightening piece and the thigh tightening piece described in the present application are both comfortable to use and reliable in use.

[0035] Sixth, when the patient lies down to sleep at night, the quilt is supported by the inverted U-shaped leg shield, so that the patient's knee joint surgery site will not be compressed, making the application more reliable. The inverted U-shaped leg shield is made of transparent material, so that medical staff can observe the patient's knee joint surgery site through it, so as to find abnormalities such as bleeding and provide timely care.

[0036] Seventh point, when the lower left edge of the inverted U-shaped leg guard is inserted downward into the left insertion groove, the left magnetic strip will magnetically fix the left metal strip, so that the lower left edge of the inverted U-shaped leg guard can be quickly fixed to the left insertion groove. Similarly, when the lower right edge of the inverted U-shaped leg guard is inserted downward into the right insertion groove, the right magnetic strip will magnetically fix the right metal strip, so that the lower right edge of the inverted U-shaped leg guard can be quickly fixed to the right insertion groove, so as to achieve good fixing stability of the inverted U-shaped leg guard and prevent circumferential displacement.

[0037] Eighth point, when the surgical site of the patient's knee joint is suspended on the hollow groove, since the bottom of the hollow groove is connected with the through groove, the invisible part of the surgical site of the patient's knee joint falling on the hollow groove can be connected with the outside through the through groove, so that the invisible part of the surgical site of the patient's knee joint falling on the hollow groove has good sweat and ventilation effect, which is conducive to the rapid recovery of related parts.

[0038] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] First, let’s briefly introduce the invention process of this patent.

[0081] The existing leg support for postoperative care of knee replacement mainly includes a leg support body made of memory foam material, and a hollow groove adapted to face the surgical site of the patient's knee joint is opened on the leg support body.

[0082] Although the above-mentioned existing leg support for post-operative care of knee replacement is widely used, the inventor of this patent found that it still has certain defects and shortcomings when using it on patients.

[0083] Specifically, on the one hand, when the patient's legs are placed on it, it is easy to fall sideways, making it unreliable for use; on the other hand, the stability of the patient's heels is not very good, making it easy for their feet to fall sideways, which can easily pull the meridians of the surgical site of the knee joint, making the surgical site of the patient's knee joint prone to complications, and the leg rest body is not convenient for fixing the drainage pipeline that may be led out from the surgical site of the patient's knee joint, and when the patient lies down to sleep at night, the quilt he covers is easy to compress the surgical site of the knee joint.

[0084] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and conducted searches and novelties to gradually conceive and design this application to solve related technical problems.

[0085] The following describes in detail the nursing foot pad 1000 after knee replacement surgery according to an embodiment of the utility model with reference to the accompanying drawings.

[0086] Reference Figures 1 to 4 As shown, a postoperative nursing foot pad 1000 for knee replacement according to an embodiment of the utility model comprises a leg support 10, a calf fastening member 20 and a thigh fastening member 30;

[0087] The leg support 10 is made of memory foam, and a leg clamping slot 101 is opened downwardly along the front-to-back direction through the front and rear end surfaces of the middle portion of the upper end surface of the leg support 10, a heel clamping slot 102 is opened downwardly near the front end of the inner bottom surface of the leg clamping slot 101, and a hollow slot 103 facing the surgical site of the patient's knee joint is opened downwardly near the middle portion of the inner bottom surface of the leg clamping slot 101;

[0088] In addition, the calf fastening member 20 is fixed to the front middle portion of the leg support 10 , and the thigh fastening member 30 is fixed to the rear middle portion of the leg support 10 .

[0089] Based on the above, it is clear that when the present application is implemented, it is mainly used as a postoperative care foot pad 1000 for knee replacement surgery.

[0090] Specifically, when applying the present application, for a patient who has undergone knee replacement surgery, after the patient lies flat on the bed, the present application is placed on the bed to raise the patient's legs after the knee replacement surgery, so that the heel of the patient after the knee replacement surgery falls into the heel clamping groove 102, and the knee joint surgery site of the patient after the knee replacement surgery falls on the hollow groove 103 and is suspended in the air, and the legs of the patient after the knee replacement surgery are slightly tightened by the calf tightening piece 20 and the thigh tightening piece 30. In this way, the present application can be easily used.

[0091] The use of the above-mentioned application will obviously have the following technical effects:

[0092] On the one hand, the leg support 10 described in the present application is made of memory foam material, which makes it flexible and can automatically deform according to the thickness of the patient's legs to adapt to and support the patient's legs, so that the part of the patient's legs in contact with it is evenly stressed and the support is comfortable. At the same time, the patient's legs are placed in the leg clamping groove 101 and are fastened by the calf fastener 20 and the thigh fastener 30, so that it is not easy to tip over and fall, so that the present application has good reliability and safety in use.

[0093] On the other hand, the patient's heel falls into the heel clamping groove 102 and is fixed therein, so that the patient's foot is not likely to tip over, thereby ensuring good stability in placement and not causing traction on the meridians of the knee joint surgery site due to tipping over, thereby preventing complications from occurring at the knee joint surgery site.

[0094] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0095] Furthermore, in a specific implementation, according to an embodiment of the present utility model, the heel clamping groove 102 is formed into a circle or a nearly circle; the hollow groove 103 is formed into a long groove shape arranged along the front-back direction.

[0096] Therefore, it is clear that based on the human body structure, the heel will be formed into a circle or a nearly circle when it is placed downward, so that when it falls into the heel clamping groove 102 formed into a circle or a nearly circle, the patient's heel will be placed more firmly.

[0097] Moreover, different patients have calves of different lengths, so that the front-to-back positions of their knee joint surgical sites will be different. Therefore, in the present application, when the hollow groove 103 is formed into a long groove shape arranged along the front-to-back direction, it can be adapted to suspend and support the knee joint surgical sites of different patients with different front-to-back positions, making the present application highly adaptable.

[0098] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0099] Furthermore, in a specific implementation, according to an embodiment of the utility model, a plurality of left pipe grooves 104 for adapting drainage pipes to pass through are evenly opened on the upper left edge of the leg clamping groove 101 from front to back downward, and the plurality of left pipe grooves 104 are all located on the left side of the hollow groove 103.

[0100] Therefore, by providing a plurality of the left pipe grooves 104, it is easy to select one of them to lead out to the left and fix the drainage line that may be led out from the patient's knee joint surgery site, making the present application convenient to use.

[0101] Moreover, in a specific implementation, according to an embodiment of the utility model, a plurality of right pipe grooves 105 for adapting drainage pipes to pass through are evenly opened from front to back downward on the upper right edge of the leg clamping groove 101, and the plurality of right pipe grooves 105 are all located on the right side of the hollow groove 103.

[0102] Therefore, by providing a plurality of the right tube grooves 105, it is easy to select one of them to lead out to the right and fix the drainage line that may be led out from the patient's knee joint surgery site, making the present application more convenient to use.

[0103] In addition, in the technical solution, according to an embodiment of the utility model, the calf fastening member 20 includes an elastic elastic band A201, a connecting band A202, a male Velcro band A203 and a female Velcro band A204 for adhering the male Velcro band A203;

[0104] Among them, the elastic band A201, the connecting band A202 and the male Velcro band A203 are connected in sequence from bottom to top, and the lower end of the elastic band A201 is fixed to the middle part of the front face of the left end of the leg rest 10; the female Velcro band A204 is vertically fixed to the middle part of the front face of the right end of the leg rest 10.

[0105] Furthermore, in a specific implementation, according to an embodiment of the present invention, the thigh fastening member 30 includes an elastic elastic band B301, a connecting band B302, a male Velcro band B303, and a female Velcro band B304 for adhering the male Velcro band B303;

[0106] Among them, the elastic band B301, the connecting band B302 and the male Velcro band B303 are connected in sequence from bottom to top, and the lower end of the elastic band B301 is fixed to the rear middle part of the left end surface of the leg support 10; the female Velcro band B304 is vertically fixed to the rear middle part of the right end surface of the leg support 10.

[0107] Therefore, when applying the present application, for a patient who has undergone knee replacement surgery, after he lies flat on the bed, the present application is placed on the bed to lift the patient's legs after the knee replacement surgery, so that the heel of the patient after the knee replacement surgery falls into the heel clamping groove 102, and the surgical part of the knee joint of the patient after the knee replacement surgery falls on the hollow groove 103 and is suspended in the air. After that, the male Velcro A can be pulled to make its appropriate position stick to the appropriate position of the female Velcro A, and the male Velcro B can be pulled to make its appropriate position stick to the appropriate position of the female Velcro B. In this way, the patient's legs can be easily fastened to be quickly fixed.

[0108] As for the use of the above-mentioned present application, since the calf tightening member 20 includes the elastic band A201 with a certain elasticity, and the thigh tightening member 30 includes the elastic band B301 with a certain elasticity, the elastic band A201 and the elastic band B301 work together to prevent the patient's legs from being rigidly tightened but can move slightly within a certain range, so that it is not easy to tighten the patient's legs and cause the skin of the legs to be damaged and ulcerated.

[0109] That is to say, through this optimized design, the calf fastener 20 and the thigh fastener 30 described in the present application are both comfortable to use and reliable to use.

[0110] Again, in this technical solution, according to an embodiment of the utility model, the present application also includes an inverted U-shaped leg shield 40;

[0111] Among them, the front-to-back length of the inverted U-shaped leg shield 40 is equal to or slightly smaller than the front-to-back length of the leg support 10; the left-right width of the lower inner part of the inverted U-shaped leg shield 40 is slightly larger than the left-right width of the leg support 10; the upper and lower heights of the inverted U-shaped leg shield 40 are larger than the upper and lower heights of the leg support 10, so as to fit the outer part of the upper part of the leg support 10, and the inverted U-shaped leg shield 40 is made of transparent material, and a tube notch groove 401 is vertically opened in the middle of the left end face and / or the middle of the right end face, and the front-to-back length of the tube notch groove 401 is equal to or slightly larger than the front-to-back length of the hollow groove 103.

[0112] In this regard, it is clear that:

[0113] On the one hand, when the patient lies down to sleep at night, the quilt he / she covers is supported by the inverted U-shaped leg shield 40, so that the surgical site of the patient's knee joint will not be compressed, making the application more reliable.

[0114] On the other hand, the inverted U-shaped leg shield 40 is made of a transparent material, so that medical staff can observe the patient's knee joint surgery site through it, so as to find abnormalities such as bleeding and provide timely care.

[0115] Furthermore, since a pipe-passing notch groove 401 is vertically opened in the middle of the left end surface and / or the middle of the right end surface of the inverted U-shaped leg shield 40, the pipe-passing notch groove 401 is opened to facilitate the drainage pipeline that may be led out from the surgical site of the patient's knee joint, so that no obstruction is formed, thereby making the inverted U-shaped leg shield 40 described in the present application reliable in use.

[0116] At the same time, as a preferred solution, according to an embodiment of the utility model, the present application also includes a support plate 50 for supporting and fixing the inverted U-shaped shield;

[0117] The front-to-back length of the support plate 50 is equal to the front-to-back length of the leg support 10, and the left-right width of the support plate 50 is greater than the left-right width of the leg support 10; the leg support 10 is fixedly arranged in the middle of the support plate 50, so that the left side of the upper end surface of the support plate 50 defines a left support surface 501, and the right side of the upper end surface of the support plate 50 defines a right support surface 502;

[0118] In addition, a left insertion groove 5011 is opened downward along the front-to-back direction on the left support surface 501 for inserting the lower left edge of the inverted U-shaped leg shield 40 downward, and a right insertion groove 5021 is opened downward along the front-to-back direction on the right support surface 502 for inserting the lower right edge of the inverted U-shaped leg shield 40 downward.

[0119] Therefore, by setting the support plate 50, the lower left edge of the inverted U-shaped leg shield 40 is inserted downward into the left insertion groove 5011 opened on its left support surface 501, and the lower right edge of the inverted U-shaped leg shield 40 is inserted downward into the right insertion groove 5021 opened on its right support surface 502, so that the inverted U-shaped leg shield 40 is firmly fixed and not easy to shift circumferentially.

[0120] On this basis, according to an embodiment of the present utility model, a left metal strip 402 is fixedly disposed on the lower left edge of the inverted U-shaped leg shield 40, and a right metal strip 403 is fixedly disposed on the lower right edge of the inverted U-shaped leg shield 40;

[0121] The bottom of the left fixing slot 5011 is fixed with a left magnetic strip 5012 adapted to magnetically fix the left metal strip 402 ; the bottom of the right fixing slot 5021 is fixed with a right magnetic strip 5022 adapted to magnetically fix the right metal strip 403 .

[0122] Therefore, when the lower left edge of the inverted U-shaped leg shield 40 is inserted downward into the left insertion groove 5011, the left magnetic strip 5012 will magnetically fix the left metal strip 402, so that the lower left edge of the inverted U-shaped leg shield 40 can be quickly fixed to the left insertion groove 5011. Similarly, when the lower right edge of the inverted U-shaped leg shield 40 is inserted downward into the right insertion groove 5021, the right magnetic strip 5022 will magnetically fix the right metal strip 403, so that the lower right edge of the inverted U-shaped leg shield 40 can be quickly fixed to the right insertion groove 5021, so as to achieve better fixing stability of the inverted U-shaped leg shield 40 and make it less prone to circumferential displacement.

[0123] The left metal strip 402, the left magnetic strip 5012, the right metal strip 403 and the right magnetic strip 5022 are all made very small so that the magnetic fixing area is very small. At this time, when the front end or the rear end of the inverted U-shaped leg shield 40 is lifted up with a little force, the left metal strip 402 can be slowly separated from the left magnetic strip 5012, and the right metal strip 403 can be slowly separated from the right magnetic strip 5022, so that the inverted U-shaped leg shield 40 is easy to take away when not in use.

[0124] Furthermore, through this optimized design, the inverted U-shaped leg shield 40 is more firmly fixed and less likely to shift circumferentially, making it extremely reliable in use.

[0125] As a preferred solution, according to an embodiment of the present invention, a through slot 503 penetrating the front and rear end surfaces of the support plate 50 is opened in the middle portion thereof; the bottom of the hollow slot 103 is connected to the through slot 503 .

[0126] In this regard, it is clear that when the surgical site of the patient's knee joint is suspended on the hollow groove 103, since the bottom of the hollow groove 103 is connected with the through groove 503, the invisible part of the surgical site of the patient's knee joint falling on the hollow groove 103 can be connected to the outside through the through groove 503, so that the invisible part of the surgical site of the patient's knee joint falling on the hollow groove 103 has good sweat and ventilation effects, which is conducive to the rapid recovery of related parts.

[0127] It should be added that, in a specific implementation, according to the knee replacement postoperative care foot pad 1000 provided in an embodiment of the utility model, the inner diameter of the heel clamping groove 102 is set at about 5.0 cm, the front-to-back length of the hollow groove 103 is set at about 20.0 cm, the front-to-back length of the leg rest 10 and the front-to-back length of the support plate 50 are both set at about 60.0 cm, the outer surface of the leg rest 10 is covered with a dirt-resistant sheath, and the lower bottom surface of the support plate 50 is formed into a serrated structure to form a non-slip surface.

[0128] Other embodiments and the like are not described here by way of example.

[0129] To sum up, in the specific implementation, the leg support 10 described in the present application is made of memory foam material, which has good flexibility and can automatically deform according to the thickness of the patient's legs to adapt to and support the patient's legs, so that the part of the patient's legs in contact with it has good force uniformity and good support comfort. At the same time, the patient's legs are placed in the leg clamping groove 101 and are fastened by the calf tightening piece 20 and the thigh tightening piece 30, so that it is not easy to tip over and fall, so that the present application has good reliability and safety in use. The patient's heel falls into the heel clamping groove 102 and is clamped and fixed, so that the patient's foot is not easy to tip over, so that the placement is stable and it is not easy to pull the meridians of the knee joint surgery site due to tipping, so that the patient's knee joint surgery site is not easy to cause complications.

[0130] Moreover, different patients have calves of different lengths, so that the front-to-back positions of their knee joint surgical sites will be different. Therefore, in the present application, when the hollow groove 103 is formed into a long groove shape arranged along the front-to-back direction, it can be adapted to suspend and support the knee joint surgical sites of different patients with different front-to-back positions, making the present application highly adaptable.

[0131] In addition, by setting up a plurality of the left tube grooves 104, it is easy to select one of them to lead out to the left and fasten the drainage line that may be led out from the patient's knee joint surgery site, making the present application convenient to use. By setting up a plurality of the right tube grooves 105, it is easy to select one of them to lead out to the right and fasten the drainage line that may be led out from the patient's knee joint surgery site, making the present application more convenient to use.

[0132] Furthermore, when applying the present application, for a patient who has undergone knee replacement surgery, after he lies flat on the bed, the present application is placed on the bed to lift the patient's legs after the knee replacement surgery, so that the heel of the patient after the knee replacement surgery falls into the heel clamping groove 102, and the surgical part of the knee joint of the patient after the knee replacement surgery falls on the hollow groove 103 and is suspended in the air. After that, the male Velcro A can be pulled to make its appropriate position stick to the appropriate position of the female Velcro A, and the male Velcro B can be pulled to make its appropriate position stick to the appropriate position of the female Velcro B. In this way, the patient's legs can be easily fastened to be quickly fixed.

[0133] Since the calf fastener 20 includes the elastic band A201 with a certain elasticity, and since the thigh fastener 30 includes the elastic band B301 with a certain elasticity, the elastic band A201 and the elastic band B301 work together so that the patient's legs will not be rigidly fastened, but can move slightly within a certain range, so that it is not easy to tighten the patient's legs and cause the skin of the legs to be damaged and ulcerated. In other words, through this optimized design, the calf fastener 20 and the thigh fastener 30 described in the present application are both comfortable to use and reliable.

[0134] Furthermore, when the patient lies down to sleep at night, the quilt is supported by the inverted U-shaped leg shield 40, so that the patient's knee joint surgery site will not be compressed, making the application more reliable. The inverted U-shaped leg shield 40 is made of transparent material, so that medical staff can observe the patient's knee joint surgery site through it, so as to find abnormalities such as bleeding and provide timely care.

[0135] Again, when the lower left edge of the inverted U-shaped leg shield 40 is inserted downward into the left insertion groove 5011, the left magnetic strip 5012 will magnetically fix the left metal strip 402, so that the lower left edge of the inverted U-shaped leg shield 40 can be quickly fixed to the left insertion groove 5011. Similarly, when the lower right edge of the inverted U-shaped leg shield 40 is inserted downward into the right insertion groove 5021, the right magnetic strip 5022 will magnetically fix the right metal strip 403, so that the lower right edge of the inverted U-shaped leg shield 40 can be quickly fixed to the right insertion groove 5021, so as to achieve the inverted U-shaped leg shield 40 with good fixing stability and not easy to shift circumferentially.

[0136] When the surgical site of the patient's knee joint is suspended on the hollow groove 103, since the bottom of the hollow groove 103 is connected with the through groove 503, the invisible part of the surgical site of the patient's knee joint falling on the hollow groove 103 can be connected to the outside through the through groove 503, so that the invisible part of the surgical site of the patient's knee joint falling on the hollow groove 103 has good sweat and ventilation effects, which is conducive to the rapid recovery of related parts.

[0137] Furthermore, the postoperative care foot pad 1000 for knee replacement provided by the present application is indeed extremely practical and has an excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
