Description

Technical Field

[0001] The utility model relates to the field of hemodialysis devices, in particular to a filtrate bag used in a dialysis machine and an assembly structure of the filtrate bag and the dialysis machine. Background Art

[0002] At present, during hemodialysis, waste liquid is mostly collected by plastic filtrate bags. In order to facilitate the placement of the plastic filtrate bag, a hanging hole is usually provided at the upper end of the plastic filtrate bag, and a supporting hook is provided on the weighing device of the dialysis machine, so that the plastic filtrate bag can be placed on the dialysis machine by hanging the supporting hook through the hanging hole (for example: the document of Chinese patent application publication number CN114828908A discloses a set of waste liquid bag and adapter). Due to the limited structural strength of the plastic filtrate bag and the heavy weight of the waste liquid collected at one time, after a period of use (most of the current plastic filtrate bags are not disposable products, and the plastic filtrate bags are respectively provided with an inlet pipe and a discharge pipe with a switch, the inlet pipe is used to guide the waste liquid in the dialysis process into the plastic filtrate bag; after the dialysis is completed, the switch on the discharge pipe is turned on to discharge the waste liquid into the centralized collector; then the switch on the discharge pipe is turned off to wait for the next input of dialysis waste liquid; so the plastic filtrate bag is hung on the supporting hook for a long time), the hanging hole of the plastic filtrate bag is prone to deformation and breakage, and the service life of the existing plastic filtrate bag is relatively short.

[0003] Although there are now filtrate bags that have two plastic plates clamping the hanging holes of the plastic filtrate bag to enhance the structural strength (for example: a CRRT-specific waste liquid collection device disclosed in the patent document with Chinese authorization announcement number CN204543034U), on such plastic filtrate bags, the two plastic plates are mostly installed by interlocking with each other through the plastic filtrate bag. In this way, the plastic filtrate bag can easily affect the stability of the interlocking of the two plastic plates, which will lead to limited stability in the installation and positioning of the two plastic plates, and further easily lead to limited reinforcement effect of the two plastic plates on the hanging holes, which is still prone to the problem of short life.

[0004] Therefore, it is necessary to redesign the structure of the filtrate bag. Utility Model Content

[0028] like Figures 1 to 3 , Figures 6 to 9 As shown, a filtrate bag used in a dialysis machine described in the utility model comprises a filtrate bag body 1 and at least one reinforcing clamp body 2, wherein the filtrate bag body 1 is a bag body with an upper end opening, and the upper end of the filtrate bag body 1 is fixedly bonded together to form a hanging portion 11; the reinforcing clamp body 2 comprises a front reinforcing plate 23 and a rear reinforcing plate 24, and the front reinforcing plate 23 is provided with a plurality of first elastic hooks 231, and the front reinforcing plate 23 and the rear reinforcing plate 24 are jointly clamped with the hanging portion 11, and each first elastic hook 231 passes through the hanging portion 11 and then is hooked on the rear reinforcing plate 24, and the front reinforcing plate 23 is respectively provided with at least one hanging hole 21 and at least one carrying hole 22, and the hanging hole 21 and the carrying hole 22 are longitudinally penetrated through the front reinforcing plate 23, the hanging portion 11, and the rear reinforcing plate 24 in sequence.

[0029] On the filtrate bag, the upper end of the filtrate bag body 1 is fixedly bonded together to form a hanging portion 11, which can ensure that the hanging portion has high structural strength. A reinforcing clamp 2 is used on the filtrate bag, and the reinforcing clamp 2 includes a front reinforcing plate 23 and a rear reinforcing plate 24; a plurality of first elastic hooks 231 are arranged on the front reinforcing plate 23, and each first elastic hook 231 passes through the hanging portion 11 and then hooks on the rear reinforcing plate 24; and at least one hanging hole 21 and at least one hand-carrying hole 22 are respectively opened on the front reinforcing plate 23, and the hanging hole 21 and the hand-carrying hole 22 are longitudinally penetrated through the front reinforcing plate 23, the hanging portion 11, and the rear reinforcing plate 24 in sequence. In this way, the front reinforcing plate 23 and the rear reinforcing plate 24 can be clamped on the hanging part 11 very stably and reliably, which can make the front reinforcing plate 23 and the rear reinforcing plate 24 play a reinforcing role more stably, which can effectively enhance the structural strength of the hanging and carrying parts, so that the filtrate bag is not prone to deformation and breakage under long-term hanging, thereby greatly extending the service life. The structural design of the filtrate bag is very reasonable and can easily meet the needs of hanging and carrying.

[0030] The upper end of the filtrate bag body 1 is fixedly bonded together by an adhesive layer to form a hanging portion 11, so that a stable and reliable hanging portion 11 can be obtained, thereby ensuring that the filtrate bag has a very high reliability.

[0031] like Figure 2 and Figure 3As shown, the front reinforcing plate 23 and the rear reinforcing plate 24 are respectively arranged at the front and rear of the hanging portion 11 , and such clamping can play a stable clamping role for the hanging portion 11 .

[0032] like Figure 3 , Figure 7 and Fig. 9 As shown, each first elastic hook 231 is located on the rear wall of the front reinforcing plate 23, and each first elastic hook 231 is arranged around the hanging hole 21, and each first elastic hook 231 passes through the hanging portion 11 and is hooked on the hanging hole 21 on the rear reinforcing plate 24. This can not only conveniently and stably connect the front reinforcing plate 23 and the rear reinforcing plate 24 together, but also ensure that the hanging place has a high structural strength and can be easily assembled, thereby helping to further improve the convenience and stability of assembly, and can make the filtrate bag have higher reliability.

[0033] like Figure 2 , Figure 7 and Fig. 9 As shown, a plurality of second elastic hooks 232 are provided on the rear wall of the front reinforcing plate 23, and the second elastic hooks 232 are arranged around the hand-carrying hole 22, and the second elastic hooks 232 pass through the hanging portion 11 and are hooked on the hand-carrying hole 22 on the rear reinforcing plate 24. This not only allows the front reinforcing plate 23 and the rear reinforcing plate 24 to be conveniently and stably connected together, but also ensures that the hand-carrying part has a high structural strength, thereby helping to further improve the convenience and stability of assembly, and can make the filtrate bag have a higher reliability.

[0034] The first elastic hook 231, the second elastic hook 232 and the front reinforcing plate 23 are integrally formed plastic or metal structures, and the rear reinforcing plate 24 is a plastic plate or a metal plate. This is not only convenient for manufacturing, but also ensures that the reinforcing clip 2 has a high structural strength.

[0035] like Figure 3 , Figure 8 and Fig. 9 As shown, a front wave surface 233 is provided on the rear wall of the front reinforcing plate 23, and the crests and troughs of the front wave surface 233 are extended transversely, and a rear wave surface 241 matching the front wave surface 233 is provided on the front wall of the rear reinforcing plate 24, and the front wave surface 233 and the rear wave surface 241 are engaged with the hanging portion 11 together. In this way, the clamping effect of the front reinforcing plate 23 and the rear reinforcing plate 24 on the hanging portion 11 can be made more stable and reliable, so that the reinforcing clamp body 2 has a stronger reinforcing effect, which helps to further improve the reliability and applicability of the filtrate bag.

[0036] like Figures 6 to 9As shown, there are two hanging holes 21, which are respectively located at the left and right ends of the reinforcing clamp body 2, and there is one carrying hole 22, which is opened in the middle of the reinforcing clamp body 2. This not only facilitates very stable hanging, but also ensures that the carrying is relatively stable, thereby helping to improve the applicability of the filtrate bag.

[0037] like Figures 6 to 9 As shown, the hand-carrying hole 22 and the two hanging holes 21 are both located in the middle of the height direction of the reinforced clamp body 2. This can provide higher structural strength and durability, thereby helping to further extend the service life of the filtrate bag.

[0038] like Figure 1 As shown, there are two reinforcing clips 2, which are arranged side by side on the hanging portion 11. In this way, when the filtrate bag body 1 is made wider, the reinforcing clips 2 do not need to be made longer, which can help control the amount of raw materials used, thereby helping to control the manufacturing cost; and this can ensure that the hanging and carrying are more stable, thereby helping to further improve the reliability and applicability of the filtrate bag.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the filtrate bag used in the dialysis machine also includes a liquid inlet tube body 3, the liquid inlet tube body 3 includes a first clamping tube 31, a first nut 32, a first hose 33, and a first Luer lock connector 34. The first clamping tube 31 is provided with a first convex ring 311 and a first external thread 312 at both ends of the outer surface, the first clamping tube 31 is arranged in the filtrate bag body 1, and the end of the first clamping tube 31 with the first external thread 312 is passed out of the filtrate bag body 1, the first nut 32 is screwed on the first external thread 312, and the first nut 32 and the first convex ring 311 are clamped together to clamp the filtrate bag body 1, one end of the first hose 33 is connected to the end of the first clamping tube 31 that passes through the filtrate bag body 1, and the first Luer lock connector 34 is connected to the other end of the first hose 33. This can not only ensure that the installation and positioning of the liquid inlet tube body 3 is very stable and reliable, but also facilitate the connection of other tube bodies, thereby helping to further improve the reliability and applicability of the filtrate bag.

[0040] like Figure 1 , Figure 2 and Figure 5As shown, the filtrate bag used in the dialysis machine also includes a liquid outlet tube body 4, which includes a second clamping tube 41, a second nut 42, a second hose 43, a second Luer lock connector 44, and a switch clip 45. The second clamping tube 41 is provided with a second convex ring 411 and a second external thread 412 at both ends of the outer surface thereof, respectively. The second clamping tube 41 is arranged in the filtrate bag body 1, and the end of the second clamping tube 41 with the second external thread 412 is passed out to the outside of the filtrate bag body 1. The second nut 42 is screwed on the second external thread 412, and the second nut 42 and the second convex ring 411 are used to clamp the filtrate bag body 1 together. One end of the second hose 43 is connected to and connected with the end of the second clamping tube 41 passing through the filtrate bag body 1. The second Luer lock connector 44 is connected to the other end of the second hose 43. The switch clip 45 is clamped on the second hose 43. This not only ensures that the installation and positioning of the liquid outlet tube body 4 is very stable and reliable, but also facilitates the docking of other tube bodies, thereby helping to further improve the reliability and applicability of the filtrate bag. Embodiment 2:

[0041] like Fig.10 As shown, the assembly structure of the filtrate bag and the dialysis machine described in Example 1 includes a filtrate bag 10 and a dialysis machine 20, and the dialysis machine 20 is provided with supporting hooks 201, the number of which is equal to the hanging holes 21 on the filtrate bag 10; the middle part of the supporting hook 201 is bent downward to form a supporting groove 202, the width K of the supporting groove 202 is greater than 2-3 times the thickness X of the reinforcing clamp 2, and the depth H of the supporting groove 202 is greater than half the height Y of the reinforcing clamp 2; each hanging hole 21 is respectively hung on the supporting groove 202 of each supporting hook 201.

[0042] In this assembly structure, the use of such a supporting groove 202 can facilitate the rapid and extremely stable limiting effect on the reinforced clamp 2. Even if the filtrate bag is severely scratched, it will not fall off, thereby greatly reducing the probability of accidents during the dialysis process, and thus allowing the dialysis to be carried out more stably.

[0043] like Fig.10 As shown, the two ends of the support hook 201 extend forward and backward respectively, the rear half of the rear end of the support hook 201 is bent upward and connected to the weighing device (not shown in the figure) of the dialysis machine 20, and the front end of the support hook 201 is extended forward longitudinally and then bent upward to form an inclined guide rod 203. This not only makes it convenient for medical staff to hang the filtrate bag, but also reduces the probability of accidental falling off during the hanging process, thereby helping to further improve the applicability of the assembly structure.
