Technical Field

[0001] The invention relates to the field of drainage bag belts, in particular to an adjustable belt for fixing a drainage bag. Background Art

[0002] A drainage bag is a medical device used to drain and collect bleeding and fluid deep inside the body or during local surgery after surgery. It is generally composed of a drainage tube and a transparent plastic bag, both of which are disposable items.

[0003] For patients who use drainage bags, in order to facilitate their normal activities, they will use a drainage bag belt to carry and fix the drainage bag. The existing drainage bag belt generally includes a belt body and a drainage bag storage bag. The drainage bag storage bag is connected to the belt body by a connecting rope. When in use, the belt body is first fixed to the patient's waist, and then the drainage bag storage bag is fixed to the thigh, and finally the drainage bag is placed in the drainage bag storage bag, so that the patient can carry it with him conveniently.

[0004] However, when using the above-mentioned drainage bag belt, the patient is likely to squat while ignoring the drainage bag. The shape of the thigh will change to a certain extent after squatting, which will cause the drainage bag to be in a tilted state with the liquid inlet facing downward. At the same time, the inside of the drainage bag is also squeezed by the thigh, causing the liquid inside the drainage bag to concentrate on the liquid inlet position of the drainage bag, which can easily cause the drainage bag to rupture. Therefore, the existing drainage bag belt is difficult to adapt to the use of patients during squatting. Summary of the invention

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

[0018] (1) Two binding mechanisms are arranged on both sides of the drainage bag storage bag to fix the drainage bag storage bag to the thigh. At the same time, when the patient squats, the deformation of the legs is used to drive the locking components to be unlocked synchronously, so that the tightening belt can adapt to the extension, thereby slowing down the pulling force of the entire binding mechanism on the drainage bag storage bag, reducing the deformation of the drainage bag storage bag, and ultimately reducing the squeezing effect on the drainage bag inside, avoiding the accumulation of liquid inside the drainage bag at the liquid inlet position and causing it to rupture, thereby playing a good protective role for the drainage bag and being able to adapt well to the patient's squatting action;

[0019] (2) By placing a placement bag inside the drainage bag storage bag and fixing the placement bag to the drainage bag storage bag with an elastic band, the placement bag is in a nearly suspended state. When the patient squats, the placement bag in the suspended state remains relatively independent from the drainage bag storage bag, which can reduce the impact of the drainage bag storage bag on the placement bag when it is deformed, thereby reducing the degree of deformation of the placement bag and further alleviating the squeezing effect on the drainage bag;

[0020] (3) By arranging a clamping body and an air bag on the placement bag for use together, when the drainage bag storage bag and the placement bag are found to be deformed, the clamping body can simultaneously clamp and fix the sealed edges on the left and right sides of the drainage bag. On the one hand, the liquid inside the drainage bag will not be too concentrated and accumulated at the liquid inlet position, thereby reducing the squeezing effect on the liquid inlet position of the drainage bag and avoiding the problem of squeezing and rupture of the drainage bag; on the other hand, it can ensure that the drainage bag will not have a large degree of positional displacement, so that it remains in a relatively stable state and will not detach from the placement bag.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] Please refer to Figure 1 and Figure 3, an adjustable belt for fixing a drainage bag, comprising: a belt body 1 for tying around the waist of a human body, the belt body 1 can be made of nylon, a connecting piece 2 is movably installed on the outer side of the belt body 1, the connecting piece 2 is a rope loop structure made of nylon material, and the position of the connecting piece 2 can be manually adjusted according to actual use requirements, and the lower end of the connecting piece 2 is vertically and side by side detachably connected with two length-adjustable hook pieces 3, the hook piece 3 is composed of a rope belt and a metal hook, and a length-adjusting rope buckle is provided on the rope belt, and the length of the rope belt can be manually controlled and adjusted; a drainage bag storage bag 4 is jointly hung at the lower ends of the two hook pieces 3, and the upper end of the drainage bag storage bag 4 is open, and is preferably made of nylon; the drainage bag storage bag 4 is movably connected to two binding mechanisms 5 on both sides along its length direction, and the binding mechanism 5 can be The drainage bag storage bag 4 is tied to the thigh position to fix the drainage bag storage bag 4. The binding mechanism 5 includes a fixing piece 51 vertically sewn to one side of the drainage bag storage bag 4. The fixing piece 51 is made of metal material, such as stainless steel. A fixing belt 52 with adjustable length is sleeved on the outer side of the fixing piece 51. A rope buckle for controlling its length is also provided on the fixing belt 52. The end of the fixing belt 52 away from the fixing piece 51 is sewn with a tightening belt 54 through an extensible elastic belt 53. The elastic belt 53 has a certain elasticity and can be an elastic belt commonly used in clothing. A locking component 55 for controlling the extension and retraction of the tightening belt 54 is fixedly connected to the end of the fixing belt 52 close to the tightening belt 54, and the elastic belt 53 is located in the locking component 55. The fixing belt 52 and the tightening belt 54 are both set to non-elastic materials.

[0031] When the adjustable belt is in use, the belt body 1 is first tied at the waist position, and then the connecting piece 2 is pulled to manually adjust it to the position corresponding to the thigh, so that the drainage bag storage bag 4 is moved to the front position of the thigh, and then the two binding mechanisms 5 are tied and connected around the human legs, so that the locking component 55 is just in contact with the legs, and when the patient squats, the legs are deformed, and the locking component 55 can be squeezed to be in an unlocked state, so that the tightening belt 54 can be stretched, reducing the pulling force of the binding mechanism 5 on the drainage bag storage bag 4, preventing the drainage bag storage bag 4 from changing to a large extent, and causing a large degree of squeezing pressure on the drainage bag, so that the drainage bag storage bag 4 can adapt well to changes in leg shape.

[0032] As another embodiment of the present invention, the number of drainage bag storage bags 4 is not limited to Figure 1As shown in the figure, it can also be adjusted according to actual usage needs. At the same time, the drainage bag storage bag 4 can also be fixed on the thigh without the binding mechanism 5. When the number of drainage bag storage bags 4 exceeds two, the length between the drainage bag storage bag 4 and the belt body 1 can be shortened, and multiple drainage bag storage bags 4 can be evenly hung on the belt body 1, so that multiple drainage bag storage bags 4 can be placed around the patient's waist to meet the usage needs of more than two drainage bags.

[0033] As an embodiment of the present invention, please refer to Figure 3 The locking component 55 includes a protective sleeve 551, the inner side wall of the protective sleeve 551 is fixedly connected to one end of the fixing belt 52, the protective sleeve 551 is movably connected to the tightening belt 54, and a U-shaped locking piece 552 inclined at ninety degrees is movably installed inside the protective sleeve 551, and the locking piece 552 is sleeved on the outer side of the tightening belt 54. The protective sleeve 551 and the locking piece 552 can both be made of hard materials, such as hard plastic and stainless steel. The vertical section of the locking piece 552 is evenly arranged with a plurality of serrations 553 along its height direction. When the locking piece 552 is not subjected to the extrusion force, the plurality of serrations 553 are tightly fitted with the outer side of the tightening belt 54, thereby locking the tightening belt 54 so that the tightening belt 54 cannot extend outward. The two horizontal sections of the locking piece 552 slide through one side of the protective sleeve 551 and are fixedly connected with a contact push piece 554 together, and the contact push piece 554 is configured to be aligned with the human leg The arc shape adapted to the part enables the contact pusher 554 to fit closely with the leg to avoid discomfort to the leg. The side of the contact pusher 554 away from the protective sleeve 551 is fixedly connected with an elastic protective pad, which can be made of silicone material to improve the softness of the side of the contact pusher 554 in contact with the leg and the comfort of the leg when in contact with the contact pusher 554. After the two binding mechanisms 5 are fixed to the leg, the two contact pushers 554 are in contact with the left and right sides of the leg, and when the left and right sides of the leg are deformed, the contact pusher 554 can be squeezed to move. Two support springs 555 are fixedly connected between the vertical section of the locking member 552 and the inner side wall of the protective sleeve 551. The elastic force of the support spring 555 should be greater than the gravity of the locking member 552 itself and the friction between the locking member 552 and the protective sleeve 551, so that the support spring 555 can drive the locking member 552 to reset.

[0034] After the patient puts on the adjustable belt and squats, the overall shape of the leg becomes flat, and the skin on the left and right sides of the leg begins to squeeze the two contact pushers 554 respectively, so that the contact pushers 554 can drive the locking member 552 to slide on the protective sleeve 551, and the sawtooth 553 gradually separates from the tightening belt 54. At the same time, the supporting spring 555 is squeezed by the locking member 552 and gradually shrinks until the sawtooth 553 is completely separated from the tightening belt 54, so that the tightening belt 54 is no longer locked and can extend outward. The retractable belt 53 is lengthened to adapt to the change in leg shape by changing the length of the tightening belt 54. When the patient adjusts from a squatting state to a standing state, the leg gradually returns to its original shape and no longer generates squeezing force on the contact pusher 554. Under the elastic force of the support spring 555, the locking member 552 is gradually reset, and the retractable belt 53 is also shortened and reset synchronously, so that the tightening belt 54 moves to the position of the serration 553 again, and finally the serration 553 is engaged with the tightening belt 54 again, thereby locking the position of the tightening belt 54.

[0035] As an embodiment of the present invention, please refer to Figure 3 , a rotating member 556 is movably penetrated on one side of the protective sleeve 551 away from the contact pushing member 554, and a resisting member 557 is fixedly connected to one end of the rotating member 556 that penetrates the inner side of the protective sleeve 551, and one side of the resisting member 557 is in contact with the vertical section of the locking member 552. The resisting member 557 and the rotating member 556 are set in the same direction, so that the rotating angles of the resisting member 557 and the rotating member 556 can be kept consistent. A through groove 558 adapted to the resisting member 557 is provided in the vertical section of the locking member 552. The contacting member 557 contacts the locking member 552, and the position of the locking member 552 can be locked, so that it will not slide when subjected to the extrusion force, thereby preventing the tightening belt 54 from stretching when the binding mechanism 5 is bound;

[0036] When the binding mechanism 5 is not bound to the leg, the resistance member 557 and the rotating member 556 are both in a horizontal state. At this time, the resistance member 557 and the through slot 558 are distributed in a cross shape, so that the resistance member 557 cannot directly pass through the through slot 558, and can lock the locking member 552 in position, so that the locking member 552 cannot slide. After the binding mechanism 5 has been fixed to the leg, the rotating member 556 can be manually rotated to drive the resistance member 557 to rotate synchronously. When the rotating member 556 rotates ninety degrees, the resistance member 557 is aligned with the through slot 558. At this time, the locking member 552 is no longer locked and can move normally.

[0037] As an embodiment of the present invention, please refer to Figure 3 and Figure 4A limiting groove 559 is provided on one side of the protective sleeve 551 close to the rotating member 556. A limiting block 5510 movably arranged inside the limiting groove 559 is fixedly connected to the outer side of the rotating member 556. The limiting block 5510 is adapted to the limiting groove 559. The rotation range inside the limiting groove 559 is set to ninety degrees. The limiting groove 559 is used to limit the limiting block 5510 to rotate ninety degrees in one direction. When the rotating member 556 is rotated, the limiting block 5510 can be driven to rotate inside the limiting groove 559. When the limiting block 5510 rotates from one side of the inner surface of the limiting groove 559 to the other side, the rotating member 556 rotates exactly ninety degrees, which plays a one-way rotation angle quick positioning function for the rotating member 556, so that the abutment 557 and the through groove 558 can be quickly aligned, which is convenient for locking and unlocking the locking member 552.

[0038] As an embodiment of the present invention, please refer to Figure 2 and Figure 6 The drainage bag storage bag 4 is provided with a stabilizing mechanism 6, which includes a placement bag 61 suspended inside the drainage bag storage bag 4, and the four corner positions of the placement bag 61 are sewn and fixed to the inner side wall of the drainage bag storage bag 4 by elastic bands 62. The placement bag 61 can be made of nylon material and is used to place the drainage bag. After the placement bag 61 is connected to the drainage bag storage bag 4 by four elastic bands 62, it is in a state of being approximately suspended inside the drainage bag storage bag 4. By utilizing the elastic effect of the elastic band 62, when the patient walks normally, the drainage bag has a certain buffering effect, so as to prevent the drainage bag from swinging too much due to the influence of the leg walking. At the same time, the placement bag 61 in the suspended state is relatively independent from the drainage bag storage bag 4, and will not be immediately affected when the drainage bag storage bag 4 is deformed, thereby reducing the deformation degree of the placement bag 61. A groove 63 for the drainage bag bottom discharge pipe to pass through is provided at the bottom of the inner side wall of the elastic band 62, and the elastic band 62 can adopt the elastic band structure commonly used in clothing;

[0039] When placing the drainage bag into the placement bag 61, the liquid inlet end of the drainage bag is facing upwards, and then the bag is placed vertically downwards in the placement bag 61. When the drainage bag moves to the lower end of the placement bag 61, the liquid outlet at the lower end of the drainage bag passes through the groove 63 until the lower end sealing edge of the tightening belt 54 contacts the bottom of the inner wall of the placement bag 61, so that the drainage bag can finally be vertically and stably placed in the placement bag 61.

[0040] As an embodiment of the present invention, please refer to Figure 5 , Figure 6 and Figure 7The two inner side walls of the placement bag 61 in the width direction are symmetrically fixedly connected with an elastic clamping body 64 for clamping and fixing the sealing position of the side edge of the drainage bag. The clamping body 64 is preferably made of rubber, and can also be other elastic materials. The two outer sides of the placement bag 61 in the length direction are symmetrically fixedly connected with two air bags 65. The air bags 65 are located between the outer side of the placement bag 61 and the inner side wall of the drainage bag storage bag 4. The side of the air bags 65 close to the drainage bag storage bag 4 is set to an arc shape. The arc-shaped air bags 65 can easily contact with the inner side wall of the drainage bag storage bag 4, and are more likely to be deformed when squeezed by the drainage bag storage bag 4. The air bags 65 are made of existing rubber materials. The airbag structure has a good quality; a cavity is arranged inside the clamping body 64, and the airbag 65 is connected with the cavity inside the clamping body 64. When the airbag 65 is squeezed, the gas inside the airbag 65 can enter the cavity of the clamping body 64, so that the clamping body 64 can expand. The clamping body 64 is provided with a clamping groove 66 in the middle position along its height direction. The clamping groove 66 is used to clamp and fix the sealing edges on the left and right sides of the drainage bag, so that the drainage bag can maintain a stable vertical state inside the placement bag 61, and the width of the clamping groove 66 is greater than the thickness of the sealing edge of the drainage bag, so as to ensure that the sealing edges on the left and right sides of the drainage bag can smoothly enter the clamping groove 66 from top to bottom;

[0041] When the drainage bag is placed in the placement bag 61, the sealed edges on the left and right sides of the drainage bag are aligned with the two clamping grooves 66 respectively, and then the bag is gradually placed downward from the upper end of the clamping groove 66, so that the sealed edges on the left and right sides of the drainage bag can enter the inside of the clamping groove 66. After the bottom of the drainage bag contacts the lower end of the inner wall of the placement bag 61, the sealed edges on the left and right sides of the drainage bag are just all in the clamping groove 66. When the patient squats, the drainage bag storage bag 4 and the placement bag 61 are deformed. At this time, the inner wall of the drainage bag storage bag 4 can generate an extrusion force on the airbag 65, so that the gas inside the airbag 65 enters the internal cavity of the clamping body 64, causing the clamping body 64 to expand. At the same time, the placement bag After the bag 61 is deformed, the clamping body 64 will be deformed as well, and the width of the clamping groove 66 will gradually decrease, and finally the clamping groove 66 will be in close contact with the sealed edges on the left and right sides of the drainage bag, so that the left and right sides of the drainage bag can be clamped and fixed to prevent the drainage bag from shifting in position during the patient's squatting process. After the patient changes from squatting to standing, the drainage bag storage bag 4 and the placement bag 61 are no longer squeezed and gradually return to their original state, and the gas inside the airbag 65 flows back into the airbag 65 again, so that the airbag 65 returns to its original state, and the clamping body 64 also returns to its original state synchronously, and the clamping groove 66 is no longer in close contact with the sealed edges on the left and right sides of the drainage bag, so that the patient can directly take out the drainage bag upwards.

[0042] As an embodiment of the present invention, please refer to Figure 1, the two tightening belts 54 are respectively provided with an adhesive structure (not marked in the figure) at one end away from the drainage bag storage bag 4, and the adhesive structure is composed of the fur surface 7 and the hook surface 8 of the Velcro, and the fur surface 7 and the hook surface 8 are respectively sewn to the ends of the two tightening belts 54 away from the fixing belt 52. Of course, the adhesive structure is not limited to the above form, and can also be other equivalent forms of structures. The two ends of the belt body 1 are respectively provided with a buckling mechanism, and the buckling mechanism adopts a male buckle 9 and a female buckle 10 structure. When the belt body 1 is tied to the waist position, the male buckle 9 and the female buckle 10 are directly aligned and snapped, so that the belt body 1 can be stably tied to the waist position.

[0043] Working principle of the present invention:

[0044] Step 1: first tie the belt body 1 to the waist and fix it through the buckle mechanism on the belt body 1 so that the belt body 1 can be stably fixed at the waist;

[0045] Step 2: After that, start to manually adjust the position of the drainage bag storage bag 4, directly pull the connecting piece 2, so that the connecting piece 2, the hook piece 3 and the drainage bag storage bag 4 move together, until the drainage bag storage bag 4 moves to the front side of the thigh position;

[0046] Step 3: Next, fix the two binding mechanisms 5 to the thighs, and keep the two binding mechanisms 5 and the thighs tightly connected by the adhesive mechanisms on the binding mechanisms 5;

[0047] Step 4: Place the drainage bag into the placement bag 61 again, with the drainage bag outlet facing downward, and align the sealed edges on the left and right sides with the two clamping grooves 66, and slowly place the drainage bag into the placement bag 61 from top to bottom, then manually rotate the rotating member 556 to release the locking effect of the locking member 552;

[0048] Step 5: During normal walking of the patient, the drainage bag storage bag 4 will move synchronously due to the continuous movement of the thigh. At this time, since the placement bag 61 is in a relatively suspended state inside the drainage bag storage bag 4, and under the elastic force of the four elastic bands 62, the placement bag 61 remains in a relatively stable state without a large degree of shaking, thereby ensuring the stability of the drainage bag;

[0049] When the patient changes from a standing position to a squatting position, the legs are deformed, triggering the two binding mechanisms 5 to adapt and extend synchronously, thereby reducing the pulling force of the binding mechanism 5 on the drainage bag storage bag 4 and reducing the degree of deformation of the drainage bag storage bag 4. At the same time, through the coordinated use of the clamping body 64 and the airbag 65, the drainage bag sealing edge can be clamped and fixed synchronously, so that the drainage bag maintains a relatively stable state inside the placement bag 61, providing sufficient space. When squeezed, the liquid can flow to other spaces, avoiding the situation where the liquid is concentrated and squeezed and ruptured due to shrinkage toward the end, so that the drainage bag will not be affected by a large degree of squeezing, and will not have a large degree of position displacement.

[0050] 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 to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention to be protected, and the scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
