DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] According to the following Figure 1-Figure 9 The anti-reflux drainage bag provided by the embodiment of the utility model is described.
[0025] Embodiment 1
[0026] The utility model discloses an anti-backflow drainage bag, comprising a bag body 100, wherein the bag body 100 is formed by connecting one end of a hard part 110 with one end of a flexible part 120, wherein one end of the hard part 110 is a sealed end and the other end is an open end, and one end of the flexible part 120 is a sealed end and the other end is an open end, and the opening sections of the two are connected to each other to form a complete bag-like structure.
[0027] A liquid inlet nozzle 300 is provided at one end of the hard part 110 away from the flexible part 120, and a liquid guide tube 400 is inserted into the liquid inlet nozzle 300, so that the body fluid can enter the hard part 110 through the liquid guide tube 400 and the liquid inlet nozzle 300. A guide plate 130 is installed in the hard part 110, and the guide plate 130 is raised at a position vertically opposite to the liquid inlet nozzle 300, and is inclined outwardly and downward, so that the body fluid can first reach the raised position, and then flow along the guide plate 130 due to its own weight, thereby realizing the diversion of the body fluid.
[0028] A through hole 132 is opened at the outer edge of the guide plate 130 along the axial direction of the bag body 100, and a one-way film tube 500 is provided below the through hole 132, so that body fluid can enter the through hole 132 along the guide plate 130, and the body fluid in the through hole 132 can pass through the one-way film tube 500 and enter the flexible part 120 for storage, and the one-way film tube 500 can prevent the internal body fluid from flowing back.
[0029] In order to prevent the one-way membrane tube 500 from being blocked by blood clots or pus, a large particle removal structure is provided between the guide plate 130 and the through hole 132 to remove large particle tissue in the body fluid, so that the body fluid entering the through hole 132 and the one-way membrane tube 500 does not contain large particle tissue, thus avoiding blockage.
[0030] Therefore, the anti-backflow drainage bag provided in this embodiment can not only resist backflow, but also prevent the one-way membrane tube 500 from being blocked by blood clots or pus, thereby ensuring the continuous operation of the one-way membrane tube 500.
[0031] After the anti-reflux drainage bag provided by the embodiment of the utility model has been used for a period of time, a new anti-reflux drainage bag is replaced, and the old anti-reflux drainage bag and the blood clots and pus stored therein are thrown into medical waste.
[0032] Optionally, the hard part 110 is polyvinyl chloride, polyethylene or polypropylene.
[0033] Preferably, the flexible portion 120 is made of soft polyvinyl chloride. In addition, scale lines may be provided on the outer surface of the flexible portion 120 to facilitate observation of the amount of body fluid.
[0034] The above-mentioned large particle removal structure is the ridge 131, which is staggeredly arranged on the upper surface of the guide plate 130, so that blood clots and pus can be blocked by the ridge 131 when passing through the ridge 131, thereby preventing blood clots and pus from entering the through hole 132, thereby ensuring the smoothness of the one-way membrane tube 500.
[0035] The hard portion 110 may be a flat cubic structure or a conical structure. When the hard portion 110 is a flat cubic structure, the entire drainage bag is a flat square drainage bag. When the hard portion 110 is a conical structure, the entire drainage bag is a round drainage bag.
[0036] like Figure 1-Figure 4 As shown, the hard portion 110 is a flat cubic structure, the guide plate 130 is a V-shaped structure, and the ridges 131 are arranged on both sides of the upper surface of the guide plate 130. In order to make the ridges 131 on one side staggered, the blood clots and pus in the body fluid entering from the liquid inlet 300 can be blocked by the ridges 131, and the body fluid can flow through the gap between the two adjacent ridges 131. Preferably, the sum of the lengths of the two adjacent ridges 131 is at least equal to the width of the guide plate 130, so that the blood clots and pus can be completely blocked in the width direction (on the body fluid flow path).
[0037] In this structure, when the product is packaged, the flexible portion 120 can be rolled up and pushed into the cavity below the V-shaped structure (such as Figure 4 ), so it takes up less space and is easy to pack.
[0038] Combination Figure 5-Figure 7As shown, the hard portion 110 is a conical structure. In this case, the guide plate 130 is a conical structure. The ridges 131 are provided with at least two layers along the circumference of the guide plate 130, and the gap length between two adjacent layers of ridges 131 is smaller than the length of the upper layer relative to the ridge 131, thereby completely blocking blood clots and pus in the circumference of the guide plate 130 (on the body fluid flow path).
[0039] In this structure, when the product is packaged, the flexible portion 120 can be rolled up and pushed into the cavity below the conical structure (such as Figure 8 ), so it takes up less space and is easy to pack.
[0040] Combination Figure 3 and Figure 7 As shown, the one-way membrane tube 500 includes a mounting ring 510 fixedly arranged on the side of the through hole 132 close to the flexible portion 120, a tube body 520 arranged on the side of the mounting ring 510 away from the guide plate 130, and a gathering portion 530 arranged at the other end of the tube body 520. The mounting ring 510 can be fixed to the lower end of the through hole 132 by bonding, and body fluid can enter the flexible portion 120 through the tube body 520 and the gathering portion 530. On the contrary, due to the gathering effect of the gathering portion 530, the body fluid in the flexible portion 120 cannot flow back.
[0041] Preferably, the one-way membrane tube 500 is made of silicone or rubber, and may also be a polyethylene film.
[0042] In order to facilitate the scraping of the device on the bedside, a hanging ring 210 is fixedly provided on one side of the hard part 110 close to the liquid inlet nozzle 300, and a hanging rope 200 is fixedly provided on the hanging ring 210, and the device can be hung on the bedside by the hanging rope 200.
[0043] Preferably, a drain pipe 600 is provided at one end of the flexible portion 120 away from the hard portion 110 , and a stop valve (not shown) is installed on the drain pipe 600 . The body fluid in the flexible portion 120 can be discharged from the drain pipe 600 by opening the stop valve.
[0044] The stop valve mentioned here can be any valve that can open or close the drain pipe 600.
[0045] Embodiment 2
[0046] The large particle removal structure is a filter 133, which is used to filter large particles in body fluids. When the hard part 110 is a flat cubic structure, two filters 133 are provided, distributed on both sides of the V-shaped structure. When the hard part 110 is a conical structure, the filter 133 is a ring structure (such as Fig. 9 ).
[0047] The working principle and use process of the utility model are as follows: when in use, body fluid enters the hard part 110 through the liquid inlet nozzle 300 and flows along the guide plate 130. During the flow, pus and blood clots are removed by the large particle removal structure, and the body fluid enters the one-way membrane tube 500 through the through hole 132 and finally flows to the flexible part 120 for storage.
[0048] In summary, the anti-backflow drainage bag can remove large particles such as blood clots and pus due to the provision of the guide plate 130 and the large particle removal structure, thereby avoiding the blockage of the one-way membrane tube 500 caused by these large particles.
