Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a peritoneal dialysis fluid exchange device. Background Art

[0002] In the prior art, for example, a peritoneal dialysis fluid exchange device with publication number CN216934242U includes a peritoneal dialysis new fluid bag, a peritoneal dialysis waste fluid bag, a new fluid infusion tube, a waste fluid drainage tube and a dialysis connector; the peritoneal dialysis new fluid bag is provided with a fluid outlet, one end of the new fluid infusion tube is connected to the fluid outlet of the peritoneal dialysis new fluid bag, and the other end is connected to the first interface of the dialysis connector; the peritoneal dialysis waste fluid bag is provided with a fluid inlet, one end of the new fluid infusion tube is connected to the fluid inlet of the peritoneal dialysis waste fluid bag, and the other end is connected to the first interface of the dialysis connector; the second interface of the dialysis connector is connected to the external tube interface of the indwelling tube in the patient's body, and a waste fluid acid-base testing device is arranged in the peritoneal dialysis waste fluid bag.

[0003] In the above scheme, by setting scale marks on the peritoneal dialysis waste bag, the patient can directly read the ultrafiltration volume on the waste bag after peritoneal dialysis. However, even if the scale is marked on the peritoneal dialysis waste bag, there is a large error between the measurement scale of the peritoneal dialysis waste bag and the actual liquid volume, and it is related to the filling degree of the peritoneal dialysis waste bag. When the peritoneal dialysis waste bag has less liquid and low filling degree, the peritoneal dialysis waste bag has more wrinkles, which makes the visual measurement value deviate greatly from the actual liquid volume. In addition, after the external short tube and the Y-type connecting tube are connected, it is difficult to fix them. The gravity of the drainage fluid or other external factors often cause the skin at the outlet to be painful, red, swollen, and bleeding, and even the polyester sheath catheter is exposed, causing tunnel inflammation, peritonitis, etc. Utility Model Content

[0023] A peritoneal dialysis fluid exchange device, such as Figure 1-2 As shown, it includes: a Y-shaped connecting tube 100, an external short tube 110, a peritoneal dialysis new fluid bag 120, a peritoneal dialysis waste fluid bag 130, a support member 140 and a fixing mechanism 200; the Y-shaped connecting tube 100 has three ports, namely a first port, a second port and a third port; the external short tube 110 is movably connected to the first port of the Y-shaped connecting tube 100; the peritoneal dialysis new fluid bag 120 is connected to the second port of the Y-shaped connecting tube 100; the peritoneal dialysis waste fluid bag 130 is connected to the third port of the Y-shaped connecting tube 100; the peritoneal dialysis new fluid bag 120 and the peritoneal dialysis waste fluid bag 130 are respectively connected to the second port and the third port of the Y-shaped connecting tube 100 in a fixed connection or a detachable connection; the support member 140 is arranged inside the peritoneal dialysis waste fluid bag 130; the fixing mechanism 200 is arranged on the external short tube 110 and the Y-shaped connecting tube 100.

[0024] By hanging the peritoneal dialysis new fluid bag 120 at a high place and placing the peritoneal dialysis waste fluid bag 130 at the lowest place, the patient then connects the external short tube 110 to the Y-type connecting tube 100 to perform fluid exchange. By setting the fixing mechanism 200, the patient can well fix the connection between the external short tube 110 and the Y-type connecting tube 100 during fluid exchange to avoid the connection between the external short tube 110 and the Y-type connecting tube 100 being pulled by the gravity of the drainage fluid or other external factors. The risk of falling off can be avoided; the external short tube 110 can be avoided from being pulled to cause skin damage and swelling at the exit, and the infection at the exit and tunnel can be prevented, thereby reducing the hospitalization rate; by arranging a support 140 in the peritoneal dialysis waste bag 130, when the fluid exchange is completed and the ultrafiltration amount of the peritoneal dialysis fluid needs to be recorded, the peritoneal dialysis waste bag 130 can be placed on a plane and pressed downward, so that the peritoneal dialysis waste bag 130 is equivalent to a rectangular transparent closed container, and the ultrafiltration amount can be accurately read.

[0025] In the embodiments of the present invention, Figure 1-2 As shown, the shape of the peritoneal dialysis waste liquid bag 130 is consistent with the shape of the square bottom valve bag; this design makes the peritoneal dialysis waste liquid bag 130 equivalent to a rectangular parallelepiped when supported by the support 140, because even if there are measuring scales engraved on the surface of the peritoneal dialysis waste liquid bag 130, there is a large error between the measuring scales of the peritoneal dialysis waste liquid bag 130 and the actual liquid volume, which is related to the filling degree of the peritoneal dialysis waste liquid bag 130, but the rectangular shape of the peritoneal dialysis waste liquid bag 130 is not affected by the filling degree of the bag body liquid, so the read ultrafiltration amount is more accurate.

[0026] In the embodiments of the present invention, Figure 1-2 As shown, the peritoneal dialysis waste bag 130 is provided with scale marks; this design facilitates reading of the ultrafiltration volume.

[0027] In the embodiments of the present invention, Figure 1-2 As shown, the support member 140 includes: a support plate 141 and a folding plate 142; the two support plates 141 are symmetrically attached to the inner wall of the peritoneal dialysis waste liquid bag 130; the two pairs of folding plates 142 are symmetrically attached to the inner wall of the peritoneal dialysis waste liquid bag 130, and the two support plates 141 and the two pairs of folding plates 142 form a rectangular support frame, and the connection points between the two support plates 141 and the two pairs of folding plates 142 are rotatably connected to each other through a rotating shaft; by forming a rectangular support frame with the two support plates 141 and the two pairs of folding plates 142, the soft peritoneal dialysis waste liquid bag 130 can be turned into a three-dimensional rectangular parallelepiped, so that the ultrafiltration amount can be directly read after the patient's fluid exchange is completed, and the ultrafiltration amount of the peritoneal dialysis fluid can be recorded, and the step of weighing the peritoneal dialysis fluid for the patient is omitted.

[0028] In the embodiments of the present invention, Figure 1-2 As shown, the two pairs of folding plates 142 are each composed of two fixed plates, and the two fixed plates are rotatably connected via a rotating shaft. This design facilitates the peritoneal dialysis waste liquid bag 130 to be folded, easy to carry, and saves storage space.

[0029] In the embodiment of the present utility model, Figure 1-2 As shown, the two support plates 141 and the two pairs of folding plates 142 are both made of hard transparent silicone material. By designing them as transparent silicone material, it does not affect the observation of the liquid in the peritoneal dialysis waste liquid bag 130 after the fluid exchange, and the hard silicone material is designed to facilitate the support of the peritoneal dialysis waste liquid bag 130.

[0030] In the embodiment of the present utility model, Figure 1-2 As shown, the fixing mechanism 200 includes: a connecting block 210, a nail button 220, a connecting strip 230, a lock buckle 240 and a belt 250; the two connecting blocks 210 are respectively fixedly connected to the Y-shaped connecting tube 100; the two nail buttons 220 are respectively arranged on the two connecting blocks 210; the connecting strip 230 is slidably sleeved on the external short tube 110, and the length of the connecting strip 230 is shorter than the length of the external short tube 110; the two lock buckles 240 are arranged on the connecting strip 230; the belt 250 is connected to the connecting strip 230; the connecting strip 230 can be directly fixedly connected to the belt 250, or the connecting strip 230 can be connected to the belt 250 by the cooperation of the nail button 220 and the lock buckle 240 or other detachable methods.

[0031] Normally, peritoneal dialysis patients will wear a belt 250 around their waists to facilitate the placement of the external short tube 110. When peritoneal dialysis is required, the external short tube 110 is first connected to the Y-shaped connecting tube 100, and then one end of the connecting strip 230 is fixedly connected to the belt 250, and then the other end of the connecting strip 230 is connected to the connecting block 210 on the Y-shaped connecting tube 100 through the cooperation of the nail buckle 220 and the lock buckle 240, and then the connection between the external short tube 110 and the Y-shaped connecting tube 100 is fixed, so as to avoid the risk of the connection between the external short tube 110 and the Y-shaped connecting tube 100 falling off when the external short tube 110 is pulled by the gravity of the drainage fluid or other external factors, and to avoid skin damage and redness and swelling at the exit when the external short tube 110 is pulled, so as to prevent the occurrence of infection at the exit and tunnel, and reduce the hospitalization rate.

[0032] In the embodiment of the present utility model, Figure 1-2 As shown, the clamp bodies 150 , two clamp bodies 150 are respectively disposed on the Y-shaped connecting tube 100 .

By setting the fixing mechanism 200, the patient can fix the connection between the external short tube 110 and the Y-type connecting tube 100 well when changing the fluid, and then the external short tube 110 and the Y-type connecting tube 100 are connected. The connection of the Y-type connecting tube 100 is fixed well to avoid the risk of the connection between the external short tube 110 and the Y-type connecting tube 100 falling off when the external short tube 110 is pulled by the gravity of the drainage fluid or other external factors, and to avoid skin damage and swelling at the outlet when the external short tube 110 is pulled, so as to prevent the occurrence of infection at the outlet and the tunnel. When the fluid exchange is completed and the ultrafiltration amount of the peritoneal dialysis fluid needs to be recorded, the peritoneal dialysis waste liquid bag 130 can be placed on a plane and pressed down, so that the peritoneal dialysis waste liquid bag 130 is equivalent to a rectangular transparent sealed container, and the ultrafiltration amount can be accurately read with the scale mark on the peritoneal dialysis waste liquid bag 130.

[0034] It should be noted that the specific models and specifications of the nail button 220 and the lock button 240 need to be selected and determined according to the actual specifications of the device, so they will not be described in detail.
