Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
In order to illustrate technical scheme described in the utility model, illustrated below by specific embodiment.
Fig. 1 shows the structure of the extracorporeal circulation blood circuit for the replaceable venous chambers that the utility model embodiment is provided, in order to
It is easy to illustrate to illustrate only the part related to the utility model embodiment.
Led as shown in figure 1, the extracorporeal circulation blood circuit for the replaceable venous chambers that the present embodiment is provided includes venous chambers 1, entrance
Pipe 2 and delivery channel 3, the arrival end of the venous chambers 1 and the grafting of entry conductor 2, the port of export of the venous chambers 1 and institute
State and clip 4 is provided with the grafting of delivery channel 3, the entry conductor 2 and delivery channel 3, the clip 4 is located at close to vein
Kettle side.
In use, by entry conductor and delivery channel with after venous chambers grafting, delivery channel tail end is connected with dialyzer,
Entry conductor head end is connected with dialysis puncture pin, after the completion of connection, open two clips, blood flow through entry conductor, venous chambers,
Delivery channel is to dialyzer.If in use, find venous chambers filter net jam, entry conductor and outlet guide can be closed
Clip on pipe, directly removes the venous chambers that venous chambers more renew, and whole operation process is very simple, without changing whole bloody path
Conduit, it is to avoid air enters dialyzer, reduces the blood loss of patient.
Venous chambers are with entry conductor and delivery channel to be detachably connected, and its sealing is critically important.Specifically connect as one kind
Mode is connect, as shown in Fig. 2 the arrival end of the venous chambers 1 is identical with outlet end structure, its head end is trapezium structure 11, center
For fluid passage 12, neck is provided with some circle grooves 13, and the entry conductor is identical with delivery channel structure, including a depression
Portion, the depressed part inwall is provided with some circle silica gel ridges 14, and the depressed part bottom sets one piece of rubber ring 15, the rubber
Cushion rubber is provided with lower counterbore 16, and the lower counterbore is identical with the trapezium structure shape, and the lower section of lower counterbore 16 is circular hole 17,
After entry conductor and delivery channel are with venous chambers grafting, the silica gel ridge 14 is just snapped onto in corresponding groove 13, institute
State trapezium structure 11 to be placed exactly in the lower counterbore 16, the fluid passage 12 is connected with the circular hole 17.
Using this attachment structure, connection installs very convenient, is completely embedded, due to the clamping of ridge and groove, simultaneously
Trapezium structure has chamfering so that conduit is difficult for drop-off, and increase rubber ring, and leak preventing effect is very good.In addition, ridge is silicon
Glue material matter, when changing venous chambers, entry conductor and delivery channel can be pulled straight out by putting forth one's strength, and Renewal process is also fairly simple.
As a kind of concrete structure of the clip 4, as shown in figure 3, including left support arm 41, middle support arm 42 and right support arm
43, the end of the left support arm 41 and right support arm 43 is a kink, and the middle leg extremities exceed the kink, and
Gap between two kinks is less than the width of the middle support arm 42.Conduit is located under left and right support arm top, middle support arm
Side, if the end of middle support arm is located at the lower section of two kinks, two kinks can block middle leg extremities, make
Obtain central conduit cut-off.When needing to open clip, directly middle leg extremities are plucked out between two kinks, this
When conduit turn on.Because in the present embodiment, the clip is metal structure, with certain degree of hardness and with certain toughness, by
Between leg extremities bend into below two kinks, and middle leg extremities are all compared from operation is plucked out between two kinks
It is more convenient.
As another structure of the clip 4, the clip 4 is plastics clip, and centre is provided with neck 44, the neck
44 one end are wide end, and the other end is narrow end, and gradually necking transits to said narrow end from the wide end, and the wide end width is not
Less than conduit diameter, said narrow end width is not more than twice of duct wall thickness.Before use, by entry conductor and delivery channel
The wide end of insertion correspondence clip neck, during use, conduit path does not influence blood circulation.When needing to change venous chambers,
Conduit is pushed into the narrow end of neck so that catheter clip is in neck narrow end, and conduit bloody path is blocked, and now takes conduit and vein apart
The junction of kettle, the venous chambers more renewed are easy to operate.This structure is compared with structure shown in Fig. 3, using plastics material
Matter, cost is lower, and the switching manipulation of clip is also more simple.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
