Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-reflux large-capacity drainage bag used for bladder flushing. Background Art

[0002] The bladder is a muscular sac-like organ that stores urine. Its shape, size, position and wall thickness vary with the degree of urine filling. Bladder irrigation is a commonly used operation technique in clinical urology. It is often used to flush out residual tissue fragments in the bladder after prostate and bladder surgery, or to clean up mucus and bleeding in the bladder. It has the effect of keeping the bladder clean, preventing obstruction and infection, and facilitating the recovery of bladder function. The waste liquid flushed out is collected in a drainage bag to avoid waste liquid discharge pollution.

[0003] For example, the public document with application number 202221981110.7 discloses a drainage bag with a negative pressure aspirator. The utility model has a negative pressure suction function and a negative pressure attraction force, which can make the liquid blood clots in the bladder flow quickly into the anti-reflux drainage bag. It is quick and convenient, and solves the problem of blood clots blocking the three-lumen catheter during bladder flushing. It realizes semi-automatic suction, saves time and effort, and is relatively easy to operate. It can effectively reduce the workload of medical staff. However, the medical silicone hose used in the drainage bag will bend and occlude under the strong pressure of negative pressure, affecting the normal and stable drainage and flushing operation. After the negative pressure suction and flushing waste liquid, due to the change in pressure difference, the pressure in the drainage bag is greater than the pressure in the pipeline, which will cause waste liquid reflux, causing urinary tract infection in patients and affecting the safety and health of patients.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-reflux large-capacity drainage bag for bladder flushing is proposed. Utility Model Content

[0005] The utility model aims to provide an anti-reflux large-capacity drainage bag for bladder flushing to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-capacity anti-reflux drainage bag for bladder flushing, comprising a drainage bag body, a connecting plug is fixedly provided through the inner wall in the middle of the upper end of the drainage bag body, an anti-reflux diaphragm is fixedly provided on the bottom end of the inner surface of the connecting plug, a drainage tube is fixedly installed on the upper end of the connecting plug, and a threaded joint is fixedly provided on the upper end of the drainage tube.

[0007] Preferably, the anti-reflux diaphragm is composed of a plurality of downwardly convexly fitted colloid elastic sealing sheets, the elastic sealing sheets are triangular in shape, and the length of the elastic sealing sheets is slightly larger than the inner radius of the connecting plug.

[0008] Preferably, the drainage tube is made of a stiff silicone material, and the shape of the threaded joint is set to be conical.

[0009] Preferably, scale lines are provided on both left and right sides of the surface of the drainage bag body, and the bag capacity of the drainage bag body is L.

[0010] Preferably, a drainage port is provided at the lower front side of the outer surface of the drainage bag body, and a guide tube is provided in the drainage port.

[0011] Preferably, a sealing cover is provided on the front side of the guide tube in the liquid discharge port, and the sealing cover is fixedly connected to one side of the front end of the guide tube via a soft rubber connecting belt.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses the anti-reflux diaphragm, drainage tube and threaded joint to set up a hard drainage tube, so that the whole pipeline is not easy to bend and block, and the flowability and anti-reflux effect are improved. The conical shape of the threaded joint gradually expands the bottom end of the catheter when it is connected with various catheter threads, making the connection tighter and more firm and not easy to fall off. When the drainage is flushed, the water flows downward through the drainage tube to push each sealing piece in the anti-reflux diaphragm to open downward, so that the waste liquid can smoothly enter the drainage bag body. Since the length of each sealing piece is slightly larger than the internal radius of the connecting plug, the sealing pieces cannot squeeze each other and then bulge upward through the center point to open, thereby achieving the anti-reflux effect, effectively preventing the waste liquid in the drainage bag body from flowing back and causing urinary tract infection.

[0014] 2. The utility model can accurately measure and count the urine volume through the arrangement of scale lines, drainage ports and sealing covers, and can seal the drainage ports through the sealing covers to form a sealed state for the entire drainage bag body, thereby reducing air pollution and avoiding frequent urine emptying.

[0019] 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.

[0020] like Figure 1-Figure 3 As shown, an anti-reflux large-capacity drainage bag for bladder flushing includes a drainage bag main body 1, a connecting plug 2 is fixedly provided through the inner wall of the middle part of the upper end of the drainage bag main body 1, an anti-reflux diaphragm 3 is fixedly provided on the bottom end of the inner surface of the connecting plug 2, a drainage tube 4 is fixedly installed on the upper end of the connecting plug 2, a threaded joint 5 is fixedly provided on the upper end of the drainage tube 4, the anti-reflux diaphragm 3 is composed of a plurality of downward convex elastic sealing sheets, and the length of each elastic sealing sheet in the anti-reflux diaphragm 3 is slightly larger than the inner radius of the connecting plug 2, the drainage tube 4 is made of stiff silicone material, and the shape of the threaded joint 5 is set to be conical, scale lines 6 are set on the left and right sides of the surface of the drainage bag main body 1, and the bag capacity of the drainage bag main body 1 is 10L, a drainage port 7 is opened at the lower front side of the outer surface of the drainage bag main body 1, and a guide tube is set in the drainage port 7, a sealing cover 8 is set on the front side of the guide tube in the drainage port 7, and the sealing cover 8 is fixedly connected to the front end side of the guide tube through a soft rubber connecting belt.

[0021] Furthermore, the anti-backflow diaphragm 3 is composed of a plurality of downwardly convex and fitted colloid elastic sealing sheets, the shape of the elastic sealing sheet is triangular, and the length of the elastic sealing sheet is slightly larger than the inner radius of the connecting plug 2, so that the elastic sealing sheet can move downward and open under the pressure from the upper side, while the elastic sealing sheet cannot flip upward and open due to the mutual deflection restriction of its own length under the pressure from the lower side, thereby preventing the backflow of dirty liquid.

[0022] Furthermore, the entire drainage tube 4 is made of hard silicone material to prevent the tube from being bent or blocked.

[0023] Furthermore, the threaded joint 5 is in a conical shape and is connected to each conduit by means of threads, and can slightly expand the lower end of the conduit to improve the sealing and firmness of the connection.

[0024] Furthermore, the scale line 6 can accurately count the urine volume.

[0025] Furthermore, the sealing cover 8 is connected to the front end of the pipe of the liquid discharge port 7 by means of a connecting belt, so that the sealing cover 8 can be opened and closed with the pipe of the liquid discharge port 7 to control the closed and open states of the liquid discharge port 7 .

[0026] Working principle: When using the anti-reflux large-capacity drainage bag for bladder flushing, first, connect the catheter to the threaded joint 5, and then seal the drainage port 7 through the sealing cover 8 to make the drainage bag body 1 form a sealed state, and then flush, the flushing waste liquid flows through the hard drainage tube 4 through the connecting plug 2, the hydraulic pressure in the drainage tube 4 continuously pushes the anti-reflux diaphragm 3, so that the tip of each elastic sealing piece moves downward in an arc shape, and the bottom end of the connecting plug 2 is opened, and the waste liquid enters the drainage bag body 1 for storage, and the urine volume entering the drainage bag body 1 is counted by the scale line 6. After the waste liquid is collected, the elastic sealing pieces in the anti-reflux diaphragm 3 are reset and sealed, so that the waste liquid is stably collected and stored inside the drainage bag body 1. If there is too much waste liquid accumulated in the drainage bag body 1, the sealing cover 8 can be pulled out to open the drainage port 7 to discharge the waste liquid. This is the working principle of the anti-reflux large-capacity drainage bag for bladder flushing.
