DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-Figure 6, is the first embodiment of the present invention, which provides a drainage bag hanging device with good stability. The drainage bag hanging device with good stability includes a fixing assembly 100, including a fixing frame 101 and a clamping member 102. The clamping member 102 is arranged on the fixing frame 101, and includes a movable sleeve 102a. The movable sleeve 102a is sleeved on the outside of the fixing frame 101, a support frame 102b is fixed to one side of the movable sleeve 102a, a movable block 102c is movably connected in the support frame 102b, a splint 102d is hinged to one side of the movable block 102c through a hinge plate, a first spring 102e is fixed to one side of the movable block 102c, a support plate 102f is fixed in the support frame 102b, and one end of the first spring 102e is fixed to the support plate 102f.

[0031] The fixing frame 101 is rectangular, and there are four groups of clamping members 102, which are respectively located above and below the two sides of the fixing frame 101. The four groups of clamping members 102 are used to clamp and fix the four corners of the drainage bag, thereby improving the stability of the drainage bag itself and preventing the drainage bag from shaking at will.

[0032] There are two clamping plates 102d in a set of clamping members 102, which are respectively located on both sides of one end of the movable block 102c. When fixing the drainage bag, the movable block 102c is pulled out of the support frame 102b, and then the corners of the drainage bag are placed between the two clamping plates 102d. At this time, a pulling force is applied to the movable block 102c by the first spring 102e to move the movable block 102c into the support frame 102b. When the clamping plate 102d contacts the inner wall of the support frame 102b, it will be squeezed by the inner wall of the support frame 102b and move toward the position of the drainage bag. In this way, the corners of the drainage bag can be clamped and fixed by the two clamping plates 102d. When the four corners of the drainage bag are fixed, the drainage bag can be effectively prevented from shaking drastically when the patient moves, thereby reducing interference with the patient's walking.

[0033] During the fixing process, the first spring 102e can continuously apply tension to the movable block 102c, and the movable block 102c can drive the splint 102d to continuously apply tension to the drainage bag, thereby further improving the stability of the drainage bag when it is fixed, and avoiding the drainage bag from becoming loose. The tension applied by the first spring 102e can only tighten the drainage bag, and will not tear the drainage bag.

[0034] The limiting component 200 is arranged on the fixed frame 101, including a positioning member 201, which is arranged on the inner side of the fixed frame 101 and includes a positioning rod 201a. The positioning rod 201a is located on the inner side of the fixed frame 101. A slot 201a-1 is opened in the positioning rod 201a. A protective strip 201b is fixed to the inner wall of the slot 201a-1. A connecting block 201c is fixed to the bottom of the support frame 102b. A support plate 201d is fixed to the bottom of the connecting block 201c. A strap 201e is fixed to the top of the support plate 201d. The top of the strap 201e is fixed to the positioning rod 201a. A card block 201f is fixed to one side of the positioning rod 201a. A card slot 101-1 is opened in the fixed frame 101, and the card block 201f slides in the card slot 101-1.

[0035] There are two groups of positioning members 201, which are located on both sides of the fixed frame 101. When the drainage bag is fixed, the drainage bag is first inserted into the slot 201a-1. The width of the slot is small, so when liquid is injected into the drainage bag, the liquid will flow into the drainage bag and be located below the positioning rod 201a. At this time, the positioning rod 201a will limit the shaking of the liquid inside the drainage bag, so that the liquid inside the drainage bag is confined to a fixed space, thereby effectively reducing the shaking amplitude of the liquid. When the patient walks or performs other activities, the liquid in the drainage bag will not fluctuate greatly, reducing interference with the patient's movements.

[0036] The connecting block 201c is used to support and fix the support plate 201d, and the bottom of the drainage bag is supported by the support plate 201d. The strap 201e is set to tighten and fix the position of the drainage bag for storing liquid, thereby further improving the stability of the drainage bag and preventing the drainage bag from shaking.

[0037] The positioning rod 201a is connected to the fixed frame 101 through the cooperation of the card block 201f and the card slot 101-1. When the liquid stored in the drainage bag increases, the positioning rod 201a will adaptively move upward to increase the space for storing liquid in the drainage bag. The side of the protective strip 201b that contacts the drainage bag is smooth and has low friction, which is used to protect the drainage bag and prevent the positioning rod 201a from scratching the drainage bag when moving.

[0038] The limiting assembly 200 also includes a rotating member 202, which is arranged in the fixed frame 101, including a rotating column 202a, the rotating column 202a is rotatably connected to the fixed frame 101, a first fixed shaft 202b is fixed in the block 201f, a first spiral groove 202a-1 is opened on the rotating column 202a, the first fixed shaft 202b slides in the first spiral groove 202a-1, a mounting plate 202c is fixed to the bottom of the movable sleeve 102a, a second spring 202d is fixed to the bottom of the mounting plate 202c, the bottom end of the second spring 202d is fixed to the inner wall of the fixed frame 101, a fixed sleeve 202e is fixed to the bottom of the mounting plate 202c, a second fixed shaft 202f is fixed in the fixed sleeve 202e, a second spiral groove 202a-2 is opened on the rotating column 202a, and the second fixed shaft 202f slides in the second spiral groove 202a-2.

[0039] There are two groups of rotating parts 202, corresponding to the two blocks 201f respectively. A movable groove is opened on the fixed frame 101. The rotating column 202a is rotatably connected with the movable groove through a bearing. The mounting plate 202c is fixed to the movable sleeve 102a below. The second spring 202d is used to support the movable sleeve 102a and the support plate 201d.

[0040] As the amount of liquid inside the drainage bag increases, the weight of the drainage bag will increase. At this time, the weight of the drainage bag itself applies downward pressure to the support plate 201d. When the support plate 201d moves downward, it will drive the support frame 102b and the movable sleeve 102a to move downward through the connecting block 201c, and drive the mounting plate 202c and the fixed sleeve 202e to move downward through the movable sleeve 102a. At this time, the second fixed shaft 202f is driven to slide in the second spiral groove 202a-2 through the fixed sleeve 202e, and the rotating column 202a is driven to rotate through the cooperation of the two. When the rotating column 202a rotates, the first fixed shaft 202b will rotate in the first spiral groove 202a-1, and the block 201f will be driven to move upward through the cooperation of the two. The positioning rod 201a can be driven to move upward through the block 201f, so that when the liquid inside the drainage bag increases, the positioning rod 201a can move upward adaptively and increase the space for storing liquid inside the drainage bag.

[0041] The pitch of the first spiral groove 202a-1 is greater than that of the second spiral groove 202a-2, so the drainage bag moves downward for a shorter distance, that is, the rotating column 202a rotates a fewer number of times, which can make the positioning rod 201a move upward for a longer distance, thereby allowing the space for storing liquid inside the drainage bag to be increased sufficiently.

[0042] When the patient makes strenuous movements during movement, such as jumping, the drainage bag will generate a large impact force downward. The second spring 202d can buffer the impact of the drainage bag to prevent the drainage bag from rupturing under the impact force.

[0043] Example 2

[0044] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, the fixing assembly 100 further includes an adjusting member 103, which is disposed on one side of the movable sleeve 102a and includes a connecting plate 103a, one side of the connecting plate 103a is fixed to the movable sleeve 102a, and a threaded column 103b is disposed in the connecting plate 103a.

[0046] There are two groups of adjusting parts 103, which correspond to the two groups of clamping parts 102 on both sides respectively. The threaded column 103b is rotatably connected to the lower connecting plate 103a through a bearing, and is connected to the upper connecting plate 103a through an internal thread. By rotating the threaded column 103b, the upper connecting plate 103a can be driven to move upward, thereby driving the upper movable sleeve 102a to move upward through the connecting plate 103a, and then the distance between the two movable sleeves 102a can be adjusted, so that drainage bags of different specifications can be clamped and fixed.

[0047] Specifically, the fixing assembly 100 also includes a pushing member 104, which is arranged in the supporting frame 102b, including a push rod 104a, the push rod 104a is inserted in the supporting plate 102f, and cooperates with the movable block 102c, the pushing plate 104b is inserted in the supporting frame 102b, and a rotating rod 104c is fixed in the pushing plate 104b, the top end of the rotating rod 104c extends to the top of the fixed frame 101, and is rotatably connected to the fixed frame 101 through a bearing.

[0048] The number of pushing members 104 corresponds to the clamping member 102, the number of push plates 104b corresponds to the support frame 102b, the push plates 104b are of sufficient length so that the support frame 102b can always be in contact with the push rod 104a after moving up and down, the support frame 102b has enough grooves for the push plates 104b to rotate, and the rotating rod 104c is used to connect and fix the two push plates 104b so that the upper and lower push plates 104b can rotate simultaneously.

[0049] When the drainage bag needs to be removed, the rotating rod 104c drives the push plate 104b to rotate, and the push plate 104b pushes the push rod 104a to move, so that the end of the push rod 104a pushes the movable block 102c to move, and pushes the movable block 102c out of the support frame 102b, thereby releasing the fixation of the drainage bag and allowing the drainage bag to be removed.

[0050] Specifically, a rotating block 104d is fixed to the top of the rotating rod 104c, and a connecting rod 104e is rotatably connected to the bottom of the rotating block 104d via a rotating shaft.

[0051] The two rotating rods 104c on both sides are connected by the cooperation of the connecting rod 104e and the rotating block 104d, so that the rotating rods 104c on both sides can rotate simultaneously, so that when the drainage bag is disassembled, the four corners of the drainage bag can be released at the same time.

[0052] Specifically, a protective pad 102d-1 is fixed to one side of the splint 102d. The provision of the protective pad 102d-1 can prevent the splint 102d from causing damage to the drainage bag when the splint 102d is clamping and fixing the drainage bag.

[0053] Specifically, a guide block 102d-2 is fixed on one side of the splint 102d, and one side of the guide block 102d-2 is inclined. When the splint 102d moves toward the inside of the support frame 102b, the inclined surface of the guide block 102d-2 will contact the inner wall of the support frame 102b. Through the cooperation of the two splints 102d, the drainage bag can be clamped more tightly, thereby preventing the drainage bag from loosening.

[0054] Example 3

[0055] Reference Figure 1-Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0056] Specifically, the positioning rod 201a is inclined, and the upper part of the end is in a pointed cone shape.

[0057] When the liquid enters the drainage bag, due to the restriction of the positioning rod 201a, the liquid will accumulate above the positioning rod 201a and flow downward along the inclined direction of the positioning rod 201a, so that the liquid can flow under the positioning rod 201a and be stored in a fixed space inside the drainage bag, thereby preventing the liquid inside the drainage bag from shaking greatly when the patient moves;

[0058] By setting the end of the positioning rod 201a to a pointed cone shape, the liquid inside the drainage bag can have enough flow space when flowing downward, thereby avoiding blockage of the liquid inside the drainage bag. If the liquid at the bottom of the drainage bag flows upward, it will be restricted to a certain extent, making its flow extremely slow, thereby avoiding the situation where the shaking of the drainage bag causes the liquid to flow upward, and when the patient falls, it can also avoid the situation where the liquid inside the drainage bag will flow back into the drainage tube.

[0059] Specifically, the strap 201e is elastic.

[0060] When the positioning rod 201a moves upward, the strap 201e is tightened, so that the strap 201e and the drainage bag fit more closely, and the drainage bag can be fixed more tightly when the liquid inside the drainage bag increases.

[0061] Specifically, it also includes a connecting belt 301 and a waist belt 302 . The connecting belt 301 is fixed to the top of the fixing frame 101 , and the waist belt 302 is fixed to the top of the connecting belt 301 .

[0062] The connecting belt 301 is made of a hard material and will not swing at will. It is used to support the fixing frame 101. By fixing the waist belt 302 to the patient's waist, the drainage bag can be suspended and fixed.

[0063] Specifically, the block 201f is T-shaped.

[0064] In summary, the drainage bag suspension device with good stability has the following advantages:

[0065] 1. The four corners of the drainage bag can be fixed at the same time, and a pulling force can be applied to the drainage bag during the fixing process, so that the fixation of the drainage bag itself can be more stable;

[0066] Second, the liquid inside the drainage bag can be confined to a fixed space, which can effectively reduce the shaking amplitude of the liquid and reduce the interference with the patient's actions. As the liquid inside the drainage bag increases, the storage space will also increase adaptively;

[0067] 3. When the patient falls, it can prevent the liquid inside the drainage bag from flowing back into the drainage tube;

[0068] 4. As the amount of liquid inside the drainage bag increases, the fastening force for fixing the drainage bag can be continuously increased;

[0069] Fifth, the second spring 202d can buffer the impact on the drainage bag caused by the patient's strenuous exercise, thereby preventing the drainage bag from rupturing under the impact force.

[0070] During use, when the drainage bag is fixed, first insert the drainage bag into the slot 201a-1, then pull the movable block 102c out of the support frame 102b, and then place the corners of the drainage bag between the two clamps 102d. At this time, the first spring 102e applies a pulling force to the movable block 102c to move the movable block 102c into the support frame 102b. When the clamp 102d contacts the inner wall of the support frame 102b, it will be squeezed by the inner wall of the support frame 102b and move toward the position of the drainage bag. In this way, the corners of the drainage bag can be clamped and fixed by the two clamps 102d. When the four corners of the drainage bag are fixed, the drainage bag can be effectively prevented from shaking drastically when the patient moves, thereby reducing interference with the patient's walking.

[0071] During the fixing process, the first spring 102e can continuously apply tension to the movable block 102c, and the movable block 102c can drive the splint 102d to continuously apply tension to the drainage bag, thereby further improving the stability of the drainage bag when fixed and preventing the drainage bag from loosening.

[0072] When liquid is injected into the drainage bag, the liquid will flow into the drainage bag and be located below the positioning rod 201a. At this time, the positioning rod 201a will limit the shaking of the liquid inside the drainage bag, so that the liquid inside the drainage bag is confined to a fixed space, thereby effectively reducing the shaking amplitude of the liquid. When the patient walks or performs other activities, the liquid in the drainage bag will not fluctuate significantly, reducing interference with the patient's movements.

[0073] As the amount of liquid inside the drainage bag increases, the weight of the drainage bag will increase. At this time, the weight of the drainage bag itself applies downward pressure to the support plate 201d. When the support plate 201d moves downward, it will drive the support frame 102b and the movable sleeve 102a to move downward through the connecting block 201c, and drive the mounting plate 202c and the fixed sleeve 202e to move downward through the movable sleeve 102a. At this time, the second fixed shaft 202f is driven to slide in the second spiral groove 202a-2 through the fixed sleeve 202e, and the rotating column 202a is driven to rotate through the cooperation of the two. When the rotating column 202a rotates, the first fixed shaft 202b will rotate in the first spiral groove 202a-1, and the block 201f will be driven to move upward through the cooperation of the two. The positioning rod 201a can be driven to move upward through the block 201f, so that when the liquid inside the drainage bag increases, the positioning rod 201a can move upward adaptively and increase the space for storing liquid inside the drainage bag.

[0074] When the positioning rod 201a moves upward, the strap 201e is tightened, so that the strap 201e and the drainage bag fit more closely, and the drainage bag can be fixed more tightly when the liquid inside the drainage bag increases.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
