Embodiment approach 1

[0078] The medical fluid communication device according to Embodiment 1 of the present invention is applied to a medical connector device for tube connection in peritoneal dialysis as an example. First, refer to Figure 1A ~ Figure 2B , the outline of the medical connector device according to this embodiment will be described. Figure 1A It is a perspective view showing the male connector 1 and the protective cap 2 constituting the medical connector device in a disassembled state. Figure 1B yes means Figure 1A The perspective view of the state where the male connector 1 and the protective cap 2 are connected together. Figure 2A It is a perspective view showing the female connector 3 constituting the medical connector device. Figure 2B yes means Figure 1A Male connector 1 shown with Figure 2A The shown perspective view of the state where the female connectors 3 are connected together.

[0079] In the present embodiment, the male connector 1 is used as the patient-si...

Embodiment approach 2

[0151] The medical liquid communication device according to Embodiment 2 of the present invention is an example of an application example of a connector device used in enteral nutrition. refer to Figure 10A ~ Figure 10B The structure of the connector device for enteral nutrition of this embodiment is demonstrated.

[0152] In enteral nutrition, liquid substances such as nutrition, liquid food, or medicine are administered through a tube leading from the patient's nasal cavity to the stomach or duodenum. When dispensing the nutrient and the like, first, the nutrient and the like are poured into the medical container. Next, the connector attached to one end of the injection line kit including the tube is connected to the port (liquid connection portion) of the medical container. Furthermore, the medical container is hung on the hook so that the port connected to the injection line kit is on the lower side. In the state where the medical container is hung on the hook, connect t...

Embodiment approach 3

[0159] The medical fluid communication device according to Embodiment 3 is an example of an application example of a medical mixed injection port device. refer to Figure 11A ~ Figure 11B , the configuration of the mixed injection port device according to this embodiment will be described.

[0160] Mixed injection port for medical treatment When administering liquid medicine to a patient, it is used to mix a liquid medicine different from the main medicine liquid into the liquid supply path for the liquid medicine supply, or to sample the liquid flowing in the liquid supply line. case and so on. Therefore, the mixed injection port is configured so that the above-mentioned operation can be performed by inserting an insertion body with a blunt tip into the insertion hole formed in the valve.

[0161] Figure 11A The illustrated mixed injection port 30 is installed in the middle of a pipe 31 to be communicated. In addition, the connected objects are not limited to pipes, and ...

Abstract

A medical device for forming a liquid communication path, comprising: joining members (1, 3) for forming the communication flow path between objects to be communicated with each other; and a protective cap (2) having a tubular shape with a closed end, holding a germicide-impregnated member (18) at the deepest end of the protective cap, and capable of being mounted to at least one of the joining members which are being separated from each other. The inner peripheral surface of the protective cap forms a space (19) for surrounding the tip of the joining member, and the dimensional relationship between the joining member and the protective cap is set so that the germicide-impregnated member (18) faces the tip of the joining member with a spacing between the members. A sealing member (8) is mounted to the inner peripheral surface of the opening end of the protective cap or to the outer peripheral surface of that portion of the joining member which corresponds to the opening end of the protective cap, and when the protective cap is in a mounted state, the sealing member is pressed between the outer peripheral surface of the joining member and the inner peripheral surface of the protective cap to form an airtight structure for the space. The mounting of the cap on the joining member effectively sterilizes the tip of the joining member and, in addition, avoids leakage of the germicide due to the contact of the joining member with the germicide-impregnated member.

Description

technical field [0001] The present invention relates to a medical liquid communication device for forming a communication flow path by coupling coupling members respectively attached to units to be connected, such as a connector device for connecting medical tubes. In particular, it relates to a liquid communication device having a structure including a protective cap capable of being attached to at least one of joint members that are separated from each other and having a sterilizing function. Background technique [0002] As a medical connector as an example of a medical liquid communication device, for example, a connector used to connect a patient-side delivery tube (extension tube) to a bag containing a dialysate when replacing the dialysate for peritoneal dialysis is known. . Peritoneal dialysis (PD) therapy is a therapy in which the dialysate is stored in the peritoneal cavity through a peritoneal catheter implanted in the peritoneal cavity of the patient in advance,...
