Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a waste liquid dumping and recycling device for a blood filtration machine. Background Technology

[0002] Blood filtration machines generate a large amount of waste fluid during operation, which is typically collected in specialized waste fluid bags. The waste fluid in these bags has a complex composition, potentially containing blood residue, drug residue, high-viscosity liquids, and other solid particles. Therefore, the treatment and recycling of this waste fluid is a crucial and indispensable part of the blood filtration treatment process.

[0003] Currently, the common method for treating waste liquid from blood filtration machines is to empty the waste liquid from the waste bag using a hoisting method. However, this traditional hoisting method suffers from significant inefficiency. In practice, due to the high viscosity of the waste liquid from blood filtration machines, the flow rate is extremely slow when the waste liquid is poured out through the waste bag outlet. Moreover, the waste liquid easily accumulates at the outlet, and over time, the accumulated waste liquid gradually dries up, leading to outlet blockage. Once blockage occurs, additional time and effort are required to clean the blocked outlet, increasing the difficulty and cost of subsequent treatment. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the above-mentioned waste liquid dumping and recycling device for blood filtration machines, this utility model is proposed.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a waste liquid dumping and recycling device for a blood filtration machine, comprising a dumping box with a placement opening on one side, at least two vertical sliding rods fixed on the top surface of the dumping box, and a support plate elastically connected to each sliding rod by a spring, the support plate maintaining an upward trend under the action of the spring force;

[0007] The top inner surface of the tilting box is fixed with a pressure block having an arc-shaped pressure layer on the bottom surface. Extrusion plates are hinged to both sides of the pressure block on the support plate. The pressure block, the two extrusion plates, and the support plate form a placement area for placing waste liquid bags. Each extrusion plate and the support plate are elastically connected by at least three springs. The support plate is driven to approach the arc-shaped pressure layer by the decreasing weight of the waste liquid bag and the elastic force of the springs, forming a squeezing effect on the placement area. The extrusion plates are also driven to deflect towards the arc-shaped pressure layer with the hinge axis as the center by the decreasing weight of the waste liquid bag and the elastic force of the springs, forming a closing effect on the placement area.

[0008] In a preferred embodiment of the waste liquid dumping and recycling device for a blood filtration machine described in this utility model, the tray and the pressure block are both inclined, and the inclination direction and angle are the same.

[0009] As a preferred embodiment of the waste liquid dumping and recycling device for a blood filtration machine described in this utility model, the end of the tray is provided with a bent portion, and a notch is provided in the center of the bent portion.

[0010] As a preferred embodiment of the waste liquid dumping and recycling device for a blood filtration machine described in this utility model, the extrusion plate has a plurality of grooves on its inclined surface facing the pressure block, and the outer walls of both sides of the pressure block are provided with a plurality of protrusions that cooperate with the grooves.

[0011] As a preferred embodiment of the waste liquid dumping and recycling device for a blood filtration machine described in this utility model, the bottom surface of the dumping box is provided with a slope, and the side of the dumping box located at the lowest end of the slope is connected to a drain pipe with a valve.

[0012] The beneficial effects of this invention are as follows: The spring and support plate work together to gradually rise as the amount of waste liquid in the bag decreases after it is placed inside. This, combined with the pressure block above, creates a squeezing effect on the waste liquid bag, improving the waste liquid discharge efficiency. Simultaneously, the two extrusion plates on the support plate move closer together as the amount of waste liquid in the bag decreases, working with the pressure block above to bend the waste liquid bag, effectively preventing the accumulation and blockage of waste liquid inside the bag and improving the efficiency of waste liquid disposal.

[0023] Reference Figures 1-4 This invention provides a waste liquid dumping and recycling device for a blood filtration machine, comprising a dumping box 1 with a placement opening on one side, a slope 11 on the bottom surface of the dumping box 1, and a drain pipe 12 with a valve connected to the side of the dumping box 1 at the lowest end of the slope 11. Through the cooperation of the slope 11 on the bottom surface of the dumping box 1 and the drain pipe 12, the waste liquid can be quickly collected along the slope 11 and discharged into the drain pipe 12 after dumping, effectively reducing the liquid residue inside the box and avoiding the risk of secondary pollution.

[0024] At least two vertical sliding rods 2 are fixed on the top surface of the pouring box 1. Each sliding rod 2 is elastically connected to a support plate 3 by a spring 21. The end of the support plate 3 is provided with a bend, which can support the bottom of the waste liquid bag and improve its placement stability. A notch is provided in the center of the bend, and the tube of the waste liquid bag extends down from the notch into the interior of the pouring box 1 to facilitate drainage.

[0025] like Figures 2-4 As shown, a pressure block 6 with an arc-shaped pressure layer 61 on the bottom surface is fixed to the inner top surface of the pouring box 1. Both the support plate 3 and the pressure block 6 are inclined, and the inclination direction and angle are the same. The inclined support plate 3 can keep the placed waste liquid bag inclined, which is convenient for the discharge of waste liquid. When the support plate 3 drives the pressure block 6 to rise, the pressure block 6 can squeeze the inclined waste liquid bag evenly. Extrusion plates 4 are hinged to the support plate 3 on both sides of the pressure block 6. Several grooves 41 are opened on the inclined surface of the extrusion plate 4 facing the pressure block 6. Several protrusions 62 that cooperate with the grooves 41 are correspondingly provided on the outer walls of both sides of the pressure block 6. The cooperation between the protrusions 62 and the grooves 41 can improve the squeezing effect on the waste liquid bag, making the discharge of waste liquid smoother and avoiding the accumulation and blockage of waste liquid. Each extrusion plate 4 and the support plate 3 are elastically connected by at least three springs 5.

[0026] The pressure block 6, the two extrusion plates 4, and the tray 3 form a placement area for the waste liquid bag. Before pouring the waste liquid, the medical staff pulls down the tray 3 and then places the waste liquid bag on the tray 3, between the two extrusion plates 4. The tubing of the waste liquid bag extends down to the bottom of the tray 3 through the notch of the bend. As the waste liquid in the waste liquid bag flows into the pouring box 1 through the tubing, the weight of the waste liquid bag gradually becomes lighter.

[0027] As the weight of the waste liquid bag gradually decreases and the elastic force of spring 21 is combined, the tray 3 is driven to approach the arc-shaped pressure layer 61, forming a squeezing effect on the placement area. With the continuous upward force of spring 21, the tray 3 can automatically adjust its height as the overall weight of the waste liquid bag gradually decreases after the waste liquid inside is poured out, so that the waste liquid bag is always in close contact with the arc-shaped pressure layer 61, realizing the gradual squeezing and drainage of the bag from bottom to top.

[0028] Furthermore, as the weight of the waste liquid bag gradually decreases and the elastic force of the spring 5 is combined, the extrusion plate 4 is driven to deflect towards the arc-shaped pressing layer 61 with the hinge axis as the center, forming a gathering effect on the placement area. At this time, the center position of the top surface of the waste liquid bag remains stationary under the pressure of the pressing block 6, and its two sides will bend towards the pressing block 6, making the waste liquid bag as a whole "V" shape, thus accelerating its waste liquid discharge efficiency.

[0029] When the waste liquid bag is discharged, resulting in a weight reduction, it triggers a double deformation due to the synergistic effect of spring 21 and spring 5:

[0030] Vertical direction: The upward movement of the tray 3 forces the waste liquid bag to contact the arc-shaped pressure layer 61, completing the extrusion of the residual liquid in the bag;

[0031] In the horizontal direction: the inward deflection of the extrusion plate 4 around the hinge axis forms a progressive clamping, causing the side wall of the waste liquid bag to wrinkle and deform, further increasing the extrusion pressure on the waste liquid and effectively preventing the accumulation and blockage of waste liquid.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
