Description
Technical Field
The present invention relates to a medical connector and a peritoneal dialysis system, and more particularly to a tube connector with a break plug and a peritoneal dialysis system with the connector.
Background
PVC and non-PVC materials are currently used medical packaging materials on the market. However, the PVC material contains the plasticizer, so that the PVC material can be separated out and enter the liquid medicine when the liquid medicine is packaged, and the PVC material causes toxicity to human bodies. The non-PVC material comprises polypropylene (PP), Polycarbonate (PC) and the like, and the material does not contain a plasticizer, has good biocompatibility and is applied to the fields of medical packaging materials and medical devices. But the price of non-PVC materials is significantly higher than PVC materials.
The properties of the non-PVC material and the PVC material are very different, so that the non-PVC material and the PVC material cannot be connected by welding and are difficult to glue. Mechanical sleeving is a relatively reliable and secure way. This requires a connector, usually with an annular flange stop in the middle of the connector, with a non-PVC pipe and PVC pipe sleeved on either side of the stop, and a break-off plug placed in the PVC pipe. Fig. 5 is a schematic structural diagram of a known break-off plug. The middle part of the breaking plug is provided with a breaking point, and the material of the breaking plug can be polycarbonate or hard PVC material, wherein the polycarbonate breaking plug is connected with the PVC pipe in a sleeved mode, and the breaking plug made of the hard PVC material is connected with the PVC pipe in a sleeved mode and then welded in a high-frequency mode. The existing break plug and the connection mode of the break plug and the PVC pipe can lead the liquid medicine to be contacted with the PVC material in the storage process, and the plasticizer in the PVC material can be separated out into the liquid medicine to damage the peritoneum of a patient; in addition, since two parts need to be processed, the production cost is greatly increased.
On the other hand, dialysis is a major method for treating uremia, and is generally classified into peritoneal dialysis and hemodialysis. Peritoneal dialysis has many advantages over hemodialysis, such as convenience of dialysis at home, low treatment costs, etc., and is gradually accepted by doctors and patients. The main complication of peritoneal dialysis is peritonitis, which can be reduced by the type design and material selection of the dialysis system, thereby improving the quality of life of peritoneal dialysis patients. However, the most PVC duplex bag dialysis systems are adopted at present, when a PVC bag is used for packaging dialysate, a plasticizer in a PVC material can be separated out, the biocompatibility of liquid medicine is reduced, and the peritoneum of a patient can be damaged after the liquid medicine enters the body of the patient.

In addition, scales can be printed on the waste liquid bag, so that a patient can conveniently read the volume number of the waste liquid bag after dialysis.
In this embodiment, the volume of the drug solution bag 1 is 2000ml, and the time for flowing the dialysate from the drug solution bag to the patient is controlled to be about 10 minutes.
As shown in fig. 4, in another embodiment of the peritoneal dialysis system of the present invention, a sampling plug 9 is disposed on the waste liquid bag 2, so that the nurse can sample and test the waste liquid, the material of the sampling plug 9 and the connecting pipe thereof are similar to the medicine adding plug 5, and the description thereof is omitted.
As can be seen from the above description, the non-PVC membrane does not contain substances harmful to human body such as plasticizer, and has good biocompatibility, therefore, the utility model discloses use non-PVC material can improve the biocompatibility of dialysate, can not harm patient's peritoneum.
In addition, in order to reduce the cost of the whole system, external connecting pipelines and waste liquid bags made of PVC materials are adopted. When the PVC connecting pipeline is connected with the non-PVC liquid medicine bag, a pipeline connector with a breaking plug is adopted to connect the PVC connecting pipeline and the non-PVC liquid medicine bag. Before the liquid medicine is used, the liquid medicine is stored in a non-PVC liquid medicine bag, and the non-PVC material does not contain a plasticizer, so that the biological safety of the liquid medicine can be ensured even if the liquid medicine is contacted with the liquid medicine for a long time. When in use, the breakable part of the connector is broken off, and the liquid medicine enters the body of a patient through the pipeline. Since the time for the liquid medicine to flow from the liquid medicine bag into the patient is about 10 minutes, the precipitation amount of the plasticizer is extremely small in such a short time and the influence on the peritoneum of the patient is negligible, although the liquid medicine passes through the PVC pipe of the external connecting pipeline in the process of flowing into the body.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
