Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a blood concentration dialysate filling anti-splashing device. Background Art

[0002] Hemodialysis fluid, the liquid that exchanges solutes with blood through diffusion across the dialysis membrane during hemodialysis, has numerous medical applications. During production, hemodialysis fluid is typically concentrated, filled into containers for sale and transportation, and then dispensed by medical staff at the point of use.

[0003] At present, filling equipment is required in the production and filling process of hemoconcentrated dialysate. For example, Chinese utility model patent No. CN218810280U discloses a dialysate filling device, which includes a liquid storage barrel, which is supported on the ground by a support rod. A conveying mechanism is provided directly below the liquid storage barrel, and the conveying mechanism is used to transport the dialysate barrel. A liquid outlet pipe and an electric telescopic rod are installed at the bottom of the liquid storage barrel, and a solenoid valve is provided on the liquid outlet pipe. A lifting pipe is provided on the outer surface of the lower end of the liquid outlet pipe, and a lifting plate is installed on the outer surface of the lifting pipe. The telescopic end of the electric telescopic rod is fixedly connected to the upper surface of the lifting plate.

[0004] The above patent has at least the following problems: the dialysate is directly filled into the liquid storage barrel through the liquid outlet pipe and the lifting pipe, which is a straight-through filling. Even if the lifting pipe is extended into the liquid storage barrel, the dialysate will still impact the bottom of the barrel and splash, causing the outside of the lifting pipe to be contaminated with dialysate. When changing the barrel, the dialysate on the outside of the lifting pipe will drip onto the transmission mechanism, causing pollution and corrosion to the equipment, reducing the service life of the equipment, affecting the workshop environment, not only increasing the maintenance cost of the equipment, but also causing waste of dialysate. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model develops a blood concentrated dialysate filling splash-proof device, which can prevent the blood concentrated dialysate from directly impacting the bottom of the barrel and causing splashing, and avoid waste, thereby effectively improving the filling effect of the blood concentrated dialysate.

[0006] The technical solution to the technical problem solved by the utility model is: a blood concentrated dialysate filling splash-proof device, comprising a first shell, a trachea is provided on one side of the first shell, a second shell is detachably provided on the bottom of the first shell, a filter screen and a bubbling device are sequentially provided in the second shell from top to bottom, the top of the side wall of the bubbling device is connected to the second shell, a plurality of groups of liquid outlets and guide strips are evenly provided on the side wall of the bubbling device, the liquid outlets and the guide strips are staggered at intervals, and a plurality of groups of first liquid outlet holes are provided on the bottom of the bubbling device.

[0007] As an optimization, the bubbler device includes a first bubbler and a second bubbler. The first bubbler has a first mounting groove on its inner sidewall, and a first baffle corresponding to the first mounting groove on its outer sidewall. The second bubbler is disposed within the first bubbler. The first and second bubblers provide dual bubble generation, enhancing the bubble effect and further preventing splashing. The first mounting groove and first baffle facilitate installation and removal of the second bubbler, facilitating maintenance.

[0008] As an optimization, a second mounting groove is provided on the inner side wall of the second housing, and a second baffle corresponding to the second mounting groove is provided on the outer side wall of the first bubbler. The second mounting groove and the second baffle facilitate installation or removal of the first bubbler and facilitate maintenance.

[0009] As an optimization, the filter is spherical, with the bottom of the filter edge abutting the tops of the first and second bubblers, and the top of the filter edge abutting the bottom of the first housing. By setting the filter to a spherical surface, the filtration area is increased, improving the filtration effect, and impurities are flushed and moved to the edges of the filter, preventing them from completely clogging the filter.

[0010] As an optimization, the bottom of the second bubbler is evenly provided with several groups of circular second liquid outlet holes, and the first liquid outlet holes are fan-shaped. The second liquid outlet holes can be provided to achieve initial bubbling; the fan-shaped first liquid outlet holes can be provided to facilitate secondary bubbling.

[0011] As an optimization, the liquid outlet is arranged between the first liquid outlet hole and the second liquid outlet hole, so that the initially foamed hemodialysis fluid can flow out from the foaming liquid outlet channel, thereby foaming again and surrounding the hemodialysis fluid flowing out of the first liquid outlet hole to prevent splashing.

[0012] As an optimization, the bottoms of the trachea, the second housing, and the bubbling device are flush, which can prevent the hemoconcentrated dialysate from splashing onto the trachea and prevent the trachea from protruding into the hemoconcentrated dialysate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The first and second shells are provided to accommodate and install a filter and a bubbling device. The air pipe is provided to allow carbon dioxide gas to be filled into the filling container to replace the air inside the filling container. The filter is provided to filter the hemoconcentrated dialysate. The bubbling device, the liquid outlet, and the guide strip form a bubbling outlet channel between the second shell, allowing the outflowing hemoconcentrated dialysate and carbon dioxide gas to fully mix and foam, reducing the flow rate, thereby preventing splashing of the hemoconcentrated dialysate when entering the filling container. The first liquid outlet is provided so that the outflowing liquid is surrounded by the bubbling outlet channel. The utility model can prevent the hemoconcentrated dialysate from directly impacting the bottom of the barrel and causing splashing, and can also avoid waste, effectively improving the filling effect of the hemoconcentrated dialysate.

DETAILED DESCRIPTION

[0020] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] Example 1

[0022] Figures 1 to 4 An embodiment of the present invention is as follows: Figures 1 to 4As shown, a blood concentration dialysate filling splash-proof device comprises a first shell 1, a trachea 2 is provided on one side of the first shell 1, a second shell 3 is detachably provided on the bottom of the first shell 1, a filter 4 and a bubbling device are provided in the second shell 3 from top to bottom, the top of the side wall of the bubbling device is connected to the second shell 3, a plurality of groups of liquid outlets 5 and guide strips 6 are evenly provided on the side wall of the bubbling device, the liquid outlets 5 and the guide strips 6 are staggered at intervals, the two side walls of the guide strip 6 are arc surfaces, the bottom of the guide strip 6 is provided with an inclined surface, the length of the guide strip 6 is less than the height of the bubbling device, so as to facilitate gas-liquid mixing, and a plurality of groups of first liquid outlets 7 are provided at the bottom of the bubbling device.

[0023] By providing a first shell 1 and a second shell 3, a filter 4 and a bubbling device can be installed; by providing an air pipe 2, carbon dioxide gas can be filled into the filling container to replace the air inside the filling container; by providing a filter 4, the blood concentrated dialysate can be filtered; by providing a bubbling device, a liquid outlet 5 and a guide strip 6, a bubbling liquid outlet channel can be formed between the second shell 3, so that the outflowing blood concentrated dialysate and carbon dioxide gas can be fully mixed to foam, thereby reducing the flow rate, thereby preventing the blood concentrated dialysate from splashing when entering the filling container, and by providing a first liquid outlet hole 7, the liquid outlet can be surrounded by the bubbling liquid outlet channel.

[0024] like Figures 2 to 4 As shown, the bubbler device includes a first bubbler 8 and a second bubbler 9. A first mounting groove 10 is provided on the inner sidewall of the first bubbler 8, and a first baffle 11 corresponding to the first mounting groove 10 is provided on the outer sidewall of the second bubbler 9. The second bubbler 9 is disposed inside the first bubbler 8. The provision of the first bubbler 8 and the second bubbler 9 enables dual bubble generation, improves the bubble effect, and further prevents splashing. The provision of the first mounting groove 10 and the first baffle 11 facilitates installation and removal of the second bubbler 9, facilitating maintenance.

[0025] like Figures 2 to 4 As shown, a second mounting groove 12 is provided on the inner side wall of the second housing 3, and a second baffle 13 is provided on the top of the outer side wall of the first bubbler 8, corresponding to the second mounting groove 12. The second mounting groove 12 and the second baffle 13 facilitate installation or removal of the first bubbler 8 and facilitate maintenance.

[0026] like Figures 2 to 4As shown, the filter screen 4 is spherical, with the center of the filter screen 4 being higher and the edges being lower. The bottom of the edge of the filter screen 4 abuts the tops of the first bubbler 8 and the second bubbler 9, and the top of the edge of the filter screen 4 abuts the bottom of the first housing 1. This facilitates installation or removal and can compress the first bubbler 8 and the second bubbler 9, improving the overall airtightness and stability. By setting the filter screen 4 as a spherical surface, the filtration area can be increased, the filtration effect can be improved, and impurities can be washed away and moved to the edges of the filter screen 4, preventing them from completely clogging the filter screen 4.

[0027] like Figures 2 to 4 As shown, the bottom of the second bubbler 9 is evenly provided with a plurality of groups of circular second liquid outlet holes 14, and the first liquid outlet hole 7 is fan-shaped. The second liquid outlet holes 14 are provided to enable initial bubbling; the fan-shaped first liquid outlet holes 7 are provided to enable secondary bubbling.

[0028] like Figures 2 to 4 As shown, the liquid outlet 5 is arranged between the first liquid outlet 7 and the second liquid outlet 14. The initially foamed hemodialysis fluid can flow out from the foaming liquid outlet channel, thereby foaming again, and can surround the hemodialysis fluid flowing out of the first liquid outlet 7 to prevent splashing.

[0029] like Figure 1 、 Figure 2 and Figure 4 As shown, the trachea 2, the second housing 3 and the bottom of the bubbling device are flush, which can prevent the hemoconcentrated dialysate from splashing onto the trachea 2 and prevent the trachea 2 from probing into the hemoconcentrated dialysate.

[0030] When in use, the top of the first shell 1 is installed to the bottom of the filling tube. During filling, the bottom of the filling tube is extended into the dialysate barrel, and the air pipe 2 fills carbon dioxide into the dialysate barrel to replace the air in the dialysate barrel. At the same time, the valve on the filling tube is opened, and the hemoconcentrated dialysate enters the first shell 1 from the filling tube, is filtered through the filter 4, enters the second bubbler 9, enters the first bubbler 8 through the second liquid outlet 14, and is initially bubbled. The hemoconcentrated dialysate in the first bubbler 8 is divided into two parts. The first part of the hemoconcentrated dialysate flows out through the first liquid outlet 7. The second part of the blood concentrated dialysate enters the bubble outlet channel between the first bubbler 8 and the second shell 3 through the liquid outlet 5 for secondary bubbling, and then flows out downward, and the second part of the blood concentrated dialysate surrounds the first part of the blood concentrated dialysate to avoid splashing. The blood concentrated dialysis after bubbling will greatly reduce the impact on the bottom of the barrel to avoid splashing. The utility model can prevent the blood concentrated dialysate from directly impacting the bottom of the barrel to cause splashing, and can also avoid waste, thereby effectively improving the filling effect of the blood concentrated dialysate.
