Description

Technical Field

[0001] The utility model relates to the technical field of liquid collection bags, in particular to a disposable liquid collection bag. Background Art

[0002] When patients undergo wound dressing changes, wound irrigation is an important treatment method. Compared with wiping with cotton swabs, wound irrigation can better clean the wound, but a large amount of waste liquid will be generated during wound irrigation. This waste liquid will not only splash onto the operator but also pollute the environment. This waste liquid needs to be collected to avoid contamination to the environment and the operator. Generally, the waste liquid is collected in a disposable liquid collection bag.

[0003] The existing Chinese patent with announcement number CN215584809U discloses a disposable liquid collection bag, including a guide plate, an arc-shaped groove is provided in the middle of the guide plate, a pressure-sensitive adhesive layer is provided on the outside of the guide plate, a release paper layer is provided on the outside of the pressure-sensitive adhesive layer, a drainage port is provided at the upper end of the guide plate, and the drainage port is a semi-funnel-shaped structure. A connecting pipe is provided at the lower end of the guide plate, and the guide plate is connected to a wastewater collection bag through the connecting pipe. The connecting pipe includes a tube body, and several bag opening clamps are provided on the outside of the tube body, and a bag opening clamp is provided between the bag opening clamps.

[0004] Although the above solution connects the wastewater collection bag through a connecting tube, ensuring the stability of the bag during the collection process and preventing the bag from falling off, the locking bolt needs to be rotated when assembling the liquid collection bag, and medical staff need to use external tools to operate, which makes the assembly process of the liquid collection bag relatively inconvenient. At the same time, the liquid collection bag lacks the function of preventing liquid backflow. If the patient or medical staff accidentally overturns the liquid collection bag during use, the process of medical staff picking up the liquid collection bag will cause a large amount of collected waste liquid to flow out, which is difficult to clean. Therefore, it does not meet the existing needs. In this regard, we have proposed a disposable liquid collection bag. Utility Model Content

[0005] The purpose of the present invention is to provide a disposable liquid collection bag to solve the problems in the above-mentioned background art that the liquid collection bag is difficult to assemble and use and lacks a backflow prevention function, which makes it easy for waste liquid to flow out and difficult to clean after being overturned.

[0006] To achieve the above object, the present invention provides the following technical solution: a disposable liquid collection bag, comprising a first collection bag body, a guide tube is provided above the first collection bag body, and the lower end of the guide tube extends into the interior of the first collection bag body;

[0011] Preferably, a pressing plate is adhered and fixed to one end of the connecting block located inside the receiving cavity, and an arc-shaped extrusion plate is adhered and fixed to one end of the connecting block located inside the annular docking groove.

[0012] Preferably, the inner upper ends of the rotating skeletons are connected by a waterproof folding cloth, and the lower end of the waterproof folding cloth is sealed and fixed to the upper end of the guide pipe.

[0013] Preferably, a return spring is provided above the rotating seat, one end of the return spring is connected to the outside of the guide tube, and the other end of the return spring is connected to the rotating skeleton.

[0014] Preferably, a guide cone is provided at the lower end of the guide tube.

[0015] Preferably, the upper end of the fixing tube is adhered and fixed to the limiting tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model has a diversion hole at the lower end of the inside of the diversion tube, and a second collection bag is provided on both sides of the front and rear sides above the first collection bag. When the first collection bag is accidentally overturned after collecting waste liquid, the curved structure of the diversion hole can prevent the waste liquid from being discharged in a straight line through the diversion tube, thereby delaying the outflow of the waste liquid. The waste liquid will accumulate on the side or upper end of the inside of the first collection bag. At this time, the waste liquid can be diverted into the second collection bag through the hose, thereby further delaying the time for the waste liquid to enter the diversion tube. When the medical staff picks up the first collection bag, a large amount of waste liquid can be avoided from flowing out, avoiding the trouble of subsequent cleaning and facilitating use.

[0018] 2. The utility model adheres and fixes the limiting block on the outer wall of the guide, so that when the first collection bag body is assembled, the upper end of the first collection bag body is stuck into the inside of the annular docking groove, and the pressing plate is pressed. The pressing plate will squeeze the outer wall of the first collection bag body through the connecting block. At this time, the medical staff only needs to rotate the fixing tube through the external thread of the outer wall of the limiting block to move the fixing tube downward to the outside of the storage cavity, so that the pressing plate can be limited so that the arc extrusion plate can firmly squeeze and fit the first collection bag body to complete the assembly. No external tools are required during the entire assembly process. Only the fixing tube needs to be simply rotated. The first collection bag body can be quickly replaced and disposable use can be quickly completed. The operation is simple and fast, and it is easy to use.

[0019] 3. The utility model provides a rotating seat on the upper side of the outer wall of the guide tube. When the first collection bag body is assembled, the fixed tube will move downward, and the downward movement of the fixed tube will drive the limiting tube to move downward synchronously. After the fixed tube moves to the outside of the storage cavity, the rotating skeleton can be rotated outward under the elastic recovery action of the reset spring, thereby stretching the waterproof folding cloth to form a funnel shape, thereby preventing waste liquid from leaking when entering. At the same time, just by observing the degree of opening of the waterproof folding cloth, it is possible to intuitively judge whether the first collection bag body is firmly fixed, thereby preventing the first collection bag body from falling due to not being firmly fixed during use, and having good practicality.

The interiors of the receiving cavities 9 are all penetrated by connecting blocks 8, and one end of the connecting block 8 extends to the interior of the annular docking groove 6. The connecting blocks 8 are slidably engaged with the receiving cavities 9 and the annular docking groove 6.

[0033] It also includes a rotating seat 14, which is arranged on the upper side of the outer wall of the guide tube 2, and four rotating seats 14 are evenly distributed in a ring. A rotating skeleton 16 is provided inside the rotating seat 14, and the rotating skeleton 16 and the rotating seat 14 are rotatably connected through a rotating shaft 15.

[0034] During use, after the upper end of the first collecting bag body 1 is inserted into the annular docking groove 6, the pressing plate 10 is moved into the interior of the storage cavity 9, and the fixing tube 11 is rotated downward to move the fixing tube 11 to the outside of the storage cavity 9, so that the pressing plate 10 can be limited. The pressing plate 10 is connected through the connecting block 8 so that the arc-shaped extrusion plate 7 can firmly squeeze the first collecting bag body 1, thereby completing the rapid assembly of the first collecting bag body 1. No external tools are required during the entire assembly process, and only the fixing tube 11 needs to be simply rotated, which is easy to use.

[0035] See also Figure 1 、 Figure 2 and Figure 7 , an external thread 12 is provided on the upper side of the outer wall of the limit block 20, a fixing tube 11 is provided on the outside of the limit block 20, and the fixing tube 11 is threadedly connected to the external thread 12, and the threaded connection between the fixing tube 11 and the external thread 12 is easy to disassemble and easy to operate;

[0036] See also Figure 2 、 Figure 4 and Figure 7 , one end of the connecting block 8 located inside the storage cavity 9 is adhered and fixed with a pressing plate 10, and one end of the connecting block 8 located inside the annular docking groove 6 is adhered and fixed with an arc-shaped extrusion plate 7. After the pressing plate 10 moves into the interior of the storage cavity 9, it can drive the connecting block 8 to make the arc-shaped extrusion plate 7 squeeze the first collection bag body 1, so that the inner wall of the upper end of the first collection bag body 1 is firmly attached to the outer wall of the guide tube 2;

[0037] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The upper ends of the inner sides of the rotating skeleton 16 are connected by a waterproof folding cloth 18, and the lower end of the waterproof folding cloth 18 is sealed and fixed to the upper end of the guide tube 2. When the waterproof folding cloth 18 is opened, it is funnel-shaped, which can prevent leakage when the waste liquid enters;

One end of the return spring 17 is connected to the outside of the guide tube 2, and the other end of the return spring 17 is connected to the rotating skeleton 16. The elastic action of the return spring 17 can rotate the rotating skeleton 16, thereby expanding the waterproof folding cloth 18.

[0039] See also Figure 5 and Figure 8 The lower end of the guide pipe 2 is provided with a guide cone 3. The setting of the guide cone 3 allows the waste liquid to smoothly enter the inside of the guide hole 4, thereby preventing the waste liquid from accumulating at the lower end of the guide pipe 2;

[0040] See also Figure 1 、 Figure 3 and Figure 6 The upper end of the fixed tube 11 is adhered and fixed with a limiting tube 13. After the limiting tube 13 moves downward, the limiting of the rotating skeleton 16 can be released, and the opening of the waterproof folding cloth 18 can be completed.

[0041] Working principle: When in use, the upper end of the first collection bag body 1 is inserted into the inside of the annular docking groove 6, and the pressing plate 10 is pressed to move the pressing plate 10 into the inside of the storage chamber 9. At this time, the pressing plate 10 will drive the arc-shaped extrusion plate 7 to squeeze the outer wall of the first collection bag body 1 through the connecting block 8, so that the inner wall of the first collection bag body 1 fits the outer wall of the guide tube 2. At this time, after grasping the fixing tube 11, it is rotated downward through the external thread 12 to rotate the fixing tube 11 to the outside of the storage chamber 9, thereby limiting the internal pressing plate 10 to prevent the pressing plate 10 from moving out The storage cavity 9 can make the arc-shaped extrusion plate 7 firmly squeeze and fit the first collection bag body 1, and quickly complete the assembly of the first collection bag body 1 without the use of additional tools. The operation is simple and convenient. When the fixed tube 11 moves down, it will be linked with the rotating skeleton 16. When the fixed tube 11 moves down, it will synchronously drive the limiting tube 13 to move down. The downward movement of the limiting tube 13 will release the limit of the four rotating skeletons 16. Under the elastic recovery action of the reset spring 17, the rotating skeleton 16 can be rotated outward through the rotating shaft 15, and the rotation of the four rotating skeletons 16 will fold the waterproof The cloth 18 is stretched out to make the waterproof folding cloth 18 into a funnel shape, thereby preventing waste liquid from leaking when entering, and the user can judge the downward movement degree of the fixing tube 11 by the degree of opening of the waterproof folding cloth 18, and then can intuitively judge whether the first collection bag body 1 is firmly fixed, thereby preventing the first collection bag body 1 from falling due to not being firmly fixed during use, and having good practicality. When collecting waste liquid, the waste liquid will enter the interior of the diversion tube 2, and then enter the diversion hole 4 through the diversion cone 3, and finally gather in the interior of the first collection bag body 1 for collection. When it is overturned, since the opening of the diversion hole 4 is located on the side of the diversion tube 2 and the curved structure of the diversion hole 4, the waste liquid can be prevented from being discharged in a straight line through the diversion tube 2, thereby delaying the time for the waste liquid to flow out. After the first collection bag body 1 falls, the waste liquid will accumulate on the side or upper end inside the first collection bag body 1. At this time, the waste liquid can be diverted to the inside of the second collection bag body 5 through the hose 19, which can further delay the time for the waste liquid to enter the diversion tube 2, so that when the medical staff picks up the first collection bag body 1, a large amount of waste liquid can be avoided from flowing out, avoiding the trouble of subsequent cleaning.
