Abstract
Closed bactericidal connector of the present invention (Closed BacteridalConnector) is called for short CB type joint, relates 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).The invention is characterized in the rotary switch that has cone-type built-in connector, be arranged in the connector body that the sterilized solution of filling with in the connector body has sealed cone-type built-in connector, adapter can be connected under the state of secluding air.
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 carbamide disease patient continuous ambulatory peritoneal dialysis (CACP).
What be used for peritoneal dialysis has sterilization and is connected tube for transfusion and abdomen and manages the liquid-transport pipe-line adapter of dual-use function thoroughly, and having now international is the Price of the U.S. advocated usefulness in 1980 Type B joint (Bactericidal Connector).One end of Type B joint is fixedly attached to 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 peritoneal dialysis liquid and flow into human body, causes sclerosing peritonitis.
Task of the present invention is to make and a kind ofly can connects the adapter of tube for transfusion and the saturating pipe of abdomen under the state of secluding air.
Feature of the present invention is the rotary switch that has cone-type built-in connector, is arranged in the connector body.The sterilized solution of filling with in the connector body has sealed cone-type built-in connector.
CB type joint when connecting tube for transfusion and abdomen and manage thoroughly, be will be connected on rotating handle on the tube for transfusion insert in the sterilized solution in the CB type adapter body and the cone-type built-in connector on the rotary switch to connecting, can realize the connection of joint under the secluding air state.Another advantage of the present invention is the outside, junction that the CB type connects the saturating pipe of H/A, has 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, has not only eliminated contact and air pollution when connecting, and easy to operate, 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.
Accompanying drawing 1 has been 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), in the connector body (4), fixed positioning key (12) is housed, packing ring (7), 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 cone-type built-in connector (18) and eccentric channel (16), 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.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, the difference of it and CB type joint shown in Figure 1.Be to take off porose nut (2) and rotating handle (1), screwed on atresia nut (17).
When going into liquid, CB type joint shown in Figure 2 is holded up, take off atresia nut (17), sterilized solution inclines, change new sterilized solution, rotating handle (1) is inserted in the sterilized solution of main body (4), stopped for 3～5 seconds, 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), the eccentric channel (16) on the rotary switch (8) and the eccentric channel (15) of 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 Fig. 2 state, CB type joint just becomes a sterilization cell, abdomen is managed thoroughly (11) outlet sealing.
Claims (4)
1, closed bactericidal connector of being made up of connector body (4), rotating handle (1), rotary switch (8), porose nut (2), separation nuts (13) and atresia nut (17) is called for short CB type joint.The invention is characterized in the rotary switch (8) that has cone-type built-in connector (18), be arranged in the connector body (4) that the sterilized solution of filling with has sealed cone-type built-in connector (18) in connector body (4).
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.
