Abstract
The present invention relates to a closed bactericidal connector called a CB type joint for short. The present invention relates to a medical transfusion pipe connector, particularly to a transfusion pipe connector used for continuous ambulatory peritoneal dialysis (CAPD) for a patient who has uremia. The present invention is characterized in that a rotary switch provided with a conical jogged type joint is arranged in a main body of the connector; the conical jogged type joint is sealed by bactericidal solution filled in the main body of the connector; therefore, the connector can be connected in the state that air is isolated.
Description
Closed bactericidal connector of the present invention (Closed Bactericidal Connector) is called for short CB type joint, relate to a kind of medical infusion pipeline adapter, especially for the liquid-transport pipe-line adapter of the patient of uremia continuous ambulatory peritoneal dialysis (CAPD).
What be used for peritoneal dialysis has sterilization and is connected tube for transfusion and film and manages the liquid-transport pipe-line adapter of dual-use function thoroughly, existing international be the price of the U.S. advocated usefulness in 1980 bactericidal connector (Bacteric-idal Connector) abbreviation Type B joint.One end of Type B joint is fixedly connected on the exit of the saturating pipe of abdomen., manage thoroughly when going into the liquid duty non-, in the Type B joint, fill with sterilized solution, and put on a hat with the clamp abdomen.When going into liquid, uncap, connect tube for transfusion, unclamp clip, promptly commutative peritoneal dialysis liquid, when the weak point of this Type B joint was to connect tube for transfusion, the junction was in open state, still can produce certain contact stain and air pollution.And sterilized solution can sneak into and flow into human body in the peritoneal dialysis liquid, causes sclerosing peritonitis.
Task of the present invention be to make a kind of can be under the state of secluding air, connect the closed bactericidal connector of tube for transfusion and the saturating pipe of abdomen, this adapter has and does not make sterilized solution sneak into the character that flows into human body in the peritoneal dialysis liquid simultaneously.
Feature of the present invention is the rotary switch that has cone-type built-in connector, is arranged in the connector body, and the sterilized solution of filling with in the connector body has sealed cone-type built-in connector.
CB type joint is when connecting tube for transfusion and abdomen and manage thoroughly, be will be connected on the tube for transfusion, in the siphunculus abrim the rotating handle of peritoneal dialysis liquid insert in the sterilized solution in the connector body, making on the embedding shape joint and rotary switch of rotating handle front end, in the passage abrim, the taper joint of peritoneal dialysis liquid can realize the saturating pipe of tube for transfusion and abdomen being connected under the secluding air state to connecting.Another advantage of the present invention is the outside, junction that the CB type connects the saturating pipe of H/A, assembled a separation nuts, in order to the contact stain that prevents this junction and the slippage of the saturating pipe of abdomen, the present invention compares with the Type B joint, not only eliminate tube for transfusion and abdomen and managed contact stain and air pollution when being connected thoroughly, and have easy to operate, the advantage of long service life.Sterilized solution can not sneaked into yet and be flowed into human body in the peritoneal dialysis liquid.
Accompanying drawing has been described one embodiment of the present of invention.
Accompanying drawing 1, the longitudinal section of CB type joint when going into liquid status.
Accompanying drawing 2, CB type joint are at non-longitudinal section when going into liquid status.
Fig. 1 has described the CB type joint when one is in into liquid status.It has a connector body (4) and a rotary rotating handle (1).One end of rotating handle (1) links to each other with tube for transfusion (19), peritoneal dialysis liquid abrim in the passage of rotating handle (1).In the connector body (4), fixed positioning key (12), packing ring (7) are housed, be provided with Cam plate (9) and (10) of eccentric channel (15), the collar (6), jump ring (5) and the rotary rotary switch (8) that has taper joint (18) and eccentric channel (16), also peritoneal dialysis liquid abrim in the eccentric channel (15) on the passage in the taper joint (18), eccentric channel (16) and Cam plate (9) and (10).Connector body (4) is managed (11) link thoroughly with abdomen and is provided with a separation nuts (13) that prevents joint slippage and contact stain.The other end of connector body (4) connects main body (4) and rotating handle (1) by a porose nut (2), also is with gasket seal (3) on the rotating handle (1).Connector body has been filled with sterilized solution in (4).
Fig. 2 has described one and has been in non-CB type joint when going into liquid status, and the difference of it and CB type joint shown in Figure 1 is to take off porose nut (2) and rotating handle (1), has screwed on atresia nut (17).At this moment, peritoneal dialysis liquid in taper joint (18) passage and the sterilized solution in the connector body (4), in the exit of taper joint (18), liquid level is in contact with one another.
When going into liquid once more, CB type joint shown in Figure 2 is holded up, taken off atresia nut (17), sterilized solution inclines.At this moment, peritoneal dialysis liquid in taper joint (18) passage can not inclined to because of siphonage, change new sterilized solution then, with in the passage abrim the rotating handle of peritoneal dialysis liquid (1) insert in the sterilized solution of connector body (4), stop 3-5 second, make the embedding shape joint (14) of rotating handle (1) front end and the taper joint (18) on the rotary switch (8) to connecting, screw porose nut (2), rotate rotating handle (1), eccentric channel (16) on the rotary switch (8) and the eccentric channel (15) on Cam plate (9) and (10) are communicated, CB type joint just transfers Fig. 1 state to, can carry out the exchange of peritoneal dialysis liquid.
After going into liquid, close rotary switch (8), take off rotating handle (1) and porose nut (2), change atresia nut (17), be returned to state shown in Figure 2, CB type joint just becomes a sterilization cell, abdomen is managed thoroughly the outlet sealing of (11).
Claims (4)
1, closed bactericidal connector of forming by connector body (4), rotating handle (1), rotary switch (8), porose nut (2), separation nuts (13) and atresia nut (17), be called for short CB type joint, it is characterized in that having the rotary switch (8) of cone-type built-in connector (18), be arranged in the connector body (4), the sterilized solution of filling with in connector body (4) has sealed cone-type built-in connector (18).
2,, it is characterized in that rotary switch (8) is provided with orthogonal eccentric channel (16) according to the CB type joint of claim 1.
3,, it is characterized in that connecting connector body (4) and rotating handle (1) by porose nut (2) according to the CB type joint of claim 2.
4,, it is characterized in that connector body (4) and abdomen manage the link of (11) thoroughly and be equipped with a separation nuts (13) according to the CB type joint of claim 1 or 2.
