Description

Technical Field

[0001] The present invention relates to the technical field of peritoneal dialysis, and in particular to a peritoneal dialysis device. Background Art

[0002] Peritoneal dialysis uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a catheter by gravity. Due to the concentration gradient difference of solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); and water moves from the hypotonic side to the hypertonic side (osmotic effect). The dialysate is continuously replaced through the peritoneal cavity to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance. Peritoneal dialysis discharges waste fluid through the peritoneal dialysis tube, and then introduces the dialysate into the peritoneal cavity through the peritoneal dialysis tube.

[0003] At present, single-tube peritoneal dialysis requires multiple assembly of drainage and inlet pipe joints, which makes the peritoneal dialysis operation complicated. After the peritoneal waste fluid is discharged through the peritoneal dialysis tube, the dialysate is introduced into the peritoneal cavity through the peritoneal dialysis tube, and the operation needs to be repeated many times. The waste fluid remaining in the peritoneal dialysis tube will return to the peritoneal cavity with the dialysate. Due to the single-tube and single-lumen design of the peritoneal dialysis tube, the cleaning fluid for cleaning the peritoneal dialysis tube also directly enters the peritoneal cavity and still needs to be discharged through the peritoneal dialysis tube. The inner cavity of the peritoneal dialysis tube cannot be cleaned independently, which affects the peritoneal dialysis effect. Summary of the invention

The micro air pump 63 and the inflation catheter 62 are used to inflate the blocking airbag 61, and the blocking airbag 61 is inflated to block the peritoneal dialysis port 32 of the peritoneal dialysis tube 3. In this embodiment, the liquid inlet catheter 11, the waste liquid catheter 21, the peritoneal dialysis tube 3, the Y-shaped tube 31, the partition interlayer 33, the connecting tube 36 and the external tube port 37 are all made of medical silicone tube material.

[0037] The cleaning mechanism includes a cleaning tank 4, a cleaning pipe 41 and a cleaning pump 42. Figure 1 and Figure 2 As shown, the external pipe port 37 is connected to the output end of the cleaning pump 42 through the cleaning pipe 41, and the input end of the cleaning pump 42 is connected to the inside of the cleaning tank 4 through the cleaning pipe 41. The external pipe port 37 and the cleaning pipe 41 are detachably sealed, and a flow meter is provided on the cleaning pipe 41. Under the action of the cleaning pump 42, the cleaning liquid in the cleaning tank 4 is transported from the external pipe port 37 to the No. 2 peritoneal dialysis circulation cavity 35, and the cleaning liquid flows from the No. 2 peritoneal dialysis circulation cavity 35 through the No. 1 peritoneal dialysis circulation cavity 34 and is collected in the waste liquid collection bag 2, thereby achieving the purpose of cleaning the peritoneal dialysis tube 3 cavity.

[0038] The peritoneal dialysis tube 3 is provided with a fixing mechanism 5 for fixing the peritoneal dialysis tube 3 outside the patient's abdominal cavity. The fixing mechanism 5 includes an adsorption plate 51, a restraining tube sleeve 53, a tube hole 54 and a spiral electric heating wire 55. Figure 5As shown. The restraining tube sleeve 53 is arranged on one side of the adsorption disk 51, and one or more annular adsorption grooves 56 are arranged on the other side of the adsorption disk 51 along the circumferential direction. The tube hole 54 passes through the middle of the restraining tube sleeve 53 and the adsorption disk 51 and is tightly matched with the restraining tube sleeve 53 and the adsorption disk 51. A spiral electric heating wire 55 is wound on the tube hole 54 and located inside the restraining tube sleeve 53. Two annular airbags 57 are arranged on the inner wall of the tube hole 54 along the circumferential direction, one of which is arranged on one side close to the restraining tube sleeve 53, and the other is arranged on the other side close to the restraining tube sleeve 53. The micro air pump 63 is installed in the restraining tube sleeve 53 and is located outside the tube hole 54. The peritoneal dialysis tube 3 passes through the tube hole 54 and the two annular air bags 57. The restraining tube sleeve 53 is close to the external pipe port 37. The two annular air bags 57 are connected to the solenoid valve II through the pipeline. The solenoid valve II is connected to the air outlet of the micro air pump 63 through the pipeline. The annular adsorption groove 56 is connected to the solenoid valve III through the pipeline. The solenoid valve III is connected to the air inlet of the micro air pump 63 through the pipeline.

[0039] In this embodiment, the two opposite sides of the adsorption disk 51 are provided with restraint belts 52, and the restraint belts 52 on the two opposite sides of the adsorption disk 51 can be connected by Velcro. For fixing the peritoneal dialysis tube 3, in addition to using a micro air pump 63 to extract the gas in the annular adsorption groove 56 on the adsorption disk 51, and then adsorbing the adsorption disk 51 outside the patient's abdominal cavity, the restraint belts 52 on the two opposite sides of the adsorption disk 51 can also be connected to the outside of the patient's abdominal cavity by Velcro. The opening of the tube hole 54 away from the side of the restraint tube sleeve 53 is a trumpet-shaped structure. After the peritoneal dialysis tube 3 is inserted into the abdominal cavity, a part of the peritoneal dialysis tube 3 remains outside the abdominal cavity. In order to avoid the part inside the abdominal cavity and the part outside the abdominal cavity bending at the abdominal cavity opening to block the passage inside the peritoneal dialysis tube 3, the trumpet-shaped structure can make the part of the peritoneal dialysis tube 3 outside the abdominal cavity and the part of the peritoneal dialysis tube 3 inside the abdominal cavity form an arc transition greater than 90 degrees at the abdominal cavity opening, which is conducive to the flow of liquid through the peritoneal dialysis tube 3.

[0040] The peritoneal dialysis device is used to perform peritoneal dialysis, and the operation includes the following steps:

[0041] 1) The part of the peritoneal dialysis tube 3 leading out of the patient's abdominal cavity is fixed by the fixing mechanism 5, the micro air pump 63 and the electromagnetic valve III are turned on, the micro air pump 63 extracts the gas in the annular adsorption groove 56 on the adsorption disk 51, and adsorbs the adsorption disk 51 outside the patient's abdominal cavity; the electromagnetic valve III is closed, the electromagnetic valve II is turned on, and the micro air pump 63 inflates the two annular air bags 57, and the two annular air bags 57 are inflated and expanded, thereby squeezing the outer wall of the peritoneal dialysis tube 3, and fixing the position of the peritoneal dialysis tube 3. The fixing mechanism 5 protects the part of the peritoneal dialysis tube 3 leading out of the patient's abdominal cavity, and the peritoneal dialysis tube 3 is easy to fix and can be reused.

[0042] 2) When discharging waste liquid, close the flow regulator 8 on the liquid inlet catheter 11, clamp the tube clamp 7 on the external pipe port 37 and close it, remove the tube clamp 7 on the connecting pipe 36, open the flow regulator 8 on the waste liquid catheter 21, and the waste liquid enters the peritoneal dialysis tube 3 from the peritoneal dialysis port 32, and the waste liquid passes through the peritoneal dialysis tube 3, the No. 1 peritoneal dialysis circulation cavity 34, the No. 2 peritoneal dialysis circulation cavity 35, the connecting pipe 36, the Y-tube 31 and the waste liquid catheter 21 and enters the waste liquid collection bag 2.

[0043] 3) After the waste liquid is discharged, the cleaning tube 41 is connected to the external pipe port 37, the tube closing clamp 7 on the external pipe port 37 is removed, the micro air pump 63 and the solenoid valve I are turned on, and air is inflated into the blocking airbag 61 through the inflation catheter 62. The blocking airbag 61 is inflated and expanded to block the peritoneal dialysis port 32 of the peritoneal dialysis tube 3. Under the action of the cleaning pump 42, the cleaning liquid in the cleaning storage tank 4 is transported from the external pipe port 37 to the No. 2 peritoneal dialysis circulation cavity 35. The cleaning liquid flows from the No. 2 peritoneal dialysis circulation cavity 35 through the No. 1 peritoneal dialysis circulation cavity 34 and is collected in the waste liquid collection bag 2, thereby achieving the purpose of cleaning the peritoneal dialysis tube 3 cavity, so that the peritoneal dialysis tube 3 that is repeated for peritoneal dialysis can reduce the contact between the dialysate and the waste liquid.

[0044] 4) When the dialysate is introduced into the peritoneal cavity, the flow rate regulator 8 on the waste liquid catheter 21 is closed, the flow rate regulator 8 on the inlet catheter 11 is opened, the tube closing clamp 7 on the connecting tube 36 is removed, and the tube closing clamp 7 is clamped on the external pipe port 37 to close; the dialysate in the dialysate bag 1 enters the No. 1 peritoneal dialysis flow cavity 34 and the No. 2 peritoneal dialysis flow cavity 35 of the peritoneal dialysis tube 3 through the inlet catheter 11 and the Y-shaped tube 31, and then flows out from the peritoneal dialysis port 32 at the end of the peritoneal dialysis tube 3 into the patient's peritoneal cavity.

[0045] 5) When two different liquids need to be infused, clamp the tube clamp 7 on the connecting tube 36, and remove the tube clamp 7 on the external tube port 37 at the same time, connect the external tube port 37 to the infusion bag through the catheter, and the liquid in the infusion bag enters the No. 2 peritoneal dialysis circulation cavity 35 from the external tube port 37, enters the end of the peritoneal dialysis tube 3 from the opening at the end of the No. 2 peritoneal dialysis circulation cavity 35, and flows out from the peritoneal dialysis port 32 into the patient's abdominal cavity, that is, through the partition interlayer 33 provided inside the peritoneal dialysis tube 3. The partition interlayer 33 divides the interior of the peritoneal dialysis tube 3 into two parts, the No. 1 peritoneal dialysis circulation cavity 34 and the No. 2 peritoneal dialysis circulation cavity 35. During peritoneal dialysis, the dual peritoneal dialysis circulation function of the peritoneal dialysis tube 3 is utilized, so that the peritoneal dialysis has the functions of dual-cavity introduction of dialysis fluid, collection of waste liquid outlet, peritoneal dialysis blocking, and cleaning of the peritoneal dialysis tube 3, and the peritoneal dialysis functionality is stronger.

[0046] 6) When the temperature of the dialysate entering the patient's abdomen is low, the spiral electric heating wire 55 in the restraining tube sleeve 53 is turned on to heat the dialysate entering the abdomen, so that the temperature of the dialysate entering the abdomen is closer to the temperature of the human peritoneal cavity, making the patient feel more comfortable.

[0047] In the prior art, when peritoneal dialysis is performed, the dialysate bag is either hung on a hook of a three-dimensional hanger, a hook set on a wall, or a hook set on a table. When in use, the dialysate bag is often caused to fall off the hook due to external factors (such as movement of the three-dimensional hanger, the operator accidentally touching the dialysate bag, or other objects touching the dialysate bag), thereby affecting peritoneal dialysis.
