Problems solved by technology

[0003] At present, in the production of water for hemodialysis, one of the important links is to use quartz sand and activated carbon to filter the water. The existing filter cartridges are generally connected to the water inlet pipe at the top and the water outlet pipe at the bottom, and the quartz sand and activated carbon are saturated inside. When it needs to be replaced, it is usually necessary to stop using the device, and then the personnel directly disassemble the entire filter cartridge for replacement, which requires a period of downtime, which affects the treatment of patients. Therefore, we propose a filter device for dialysis equipment used in nephrology

Embodiment 1

[0026] see Figure 1-Figure 4 , a filter device for dialysis equipment for nephrology in the figure, including a filter box 1, the top and bottom of the filter box 1 are fixed with an isolation plate 2, and the top of the filter box 1 is installed with a Z-type plate 3, Z-type plate 3 A partition plate 4 is fixed between the isolation plate 2 at the bottom end, the top and bottom ends of the filter box 1 are respectively connected with a liquid inlet pipe 5 and a liquid outlet pipe 6, and the outer side of the filter box 1 corresponds to the two isolation plates 2. There is a closing door 37 , two filters 7 are installed between the two isolation plates 2 , and a docking mechanism 8 is installed on the Z-shaped plate 3 to connect with the two filters 7 in sequence.

[0027] It should be noted that: in this solution, the filter box 1 is installed in the dialysate supply system in the dialysis equipment through existing parts such as screw mounting plates.

Embodiment 2

[0040] see Figure 4 , This embodiment further describes Example 1. The liquid outlet in the figure is slidably inserted with an I-shaped pipe 33, and the I-shaped pipe 33 is slidably sleeved with the liquid outlet column 28, and the outer side of the I-shaped pipe 33 is sleeved with a push-tight Spring 34.

[0041] It is worth noting that when personnel disassemble the filter 7 , by pressing downward, the liquid inlet column 27 can be easily moved down, so as to be easily separated from the docking sliding sleeve 18 and the docking fixed sleeve 24 .

[0042] In addition, in this solution, in order to make disassembly more convenient, the bottom end of the liquid outlet column 28 is rounded, and the top of the I-shaped pipe 33 is fixed with a plurality of contact protrusions 36 .

Embodiment 3

[0044] see image 3 In this embodiment, other embodiments are further described. The top end of the partition plate 4 in the figure is correspondingly fixed with an abutment plate 35 that is clamped to the liquid inlet column 27 .

[0045] It should be noted that: the abutting plate 35 can be stuck at the position of the liquid inlet column 27, and can offset the filter cartridge 26, so that when the bottom push spring 34 is pushed, it can be stably limited, making the installation more stable.

Abstract

The invention discloses a filter device of dialysis equipment for the nephrology department, relates to the technical field of permeation equipment, solves the problem that shutdown operation is needed when a filter in the permeation equipment is replaced, and comprises a filter box, isolation plates are fixed to the top and the bottom of the filter box, and a Z-shaped plate is installed at the top end of the filter box; a partition plate is fixed between the Z-shaped plate and the partition plate at the bottom end, the top and the bottom end of the filter box are communicated with a liquid inlet pipe and a liquid outlet pipe respectively, a closing door is rotationally installed on the outer side of the filter box and corresponds to the position between the two partition plates, two filters are installed between the two partition plates, and a butt joint mechanism which is in butt joint with the two filters in sequence is installed on the Z-shaped plate; according to the dialysis machine, the two filters are installed in the filter box, and butt joint of one filter is controlled through the butt joint mechanism, so that shutdown operation is not needed when one filter is replaced, and the dialysis machine can work without shutdown.

Description

technical field [0001] The invention relates to the technical field of osmotic equipment, in particular to a filtering device for dialysis equipment used in nephrology. Background technique [0002] The hemodialysis device uses the principle of semi-permeable membrane to exchange or discharge various harmful and excess metabolic wastes and excess electrolytes in the patient's blood through diffusion, convection and filtration. The semi-permeable dialysis membrane (dialyzer) exchanges substances with the solutes in the dialysate through the principle of dispersion. The excessive accumulation of toxic and harmful substances in the blood diffuses to the dialysate side due to the high concentration and is discharged from the body. Electrolytes and bases that are necessary for the body in the liquid also enter the body through diffusion to correct the imbalance of electrolyte and acid-base balance. Excessive accumulation of water in the body can be removed by using the difference...
