Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in figure 1, a dialysis pipeline connecting structure comprises a first pipeline 1, a second pipeline 2 for transfusion into the first pipeline 1 and a limiting component, wherein the end part of the first pipeline 1 is connected with the end part of the second pipeline 2 in a clamping way, the limiting component comprises two connecting discs 3, a plurality of connecting rods 4 which have elasticity and can be bent and a plurality of limiting blocks 5, the two connecting discs 3 are respectively fixedly sleeved on the first pipeline 1 and the second pipeline 2 in a one-to-one correspondence way, one end of each connecting rod 4 is fixed on the same side of one connecting disc 3, the other end of each connecting rod 4 is fixedly connected with a plurality of limiting blocks 5 in a one-to-one correspondence way, a plurality of clamping grooves 6 are arranged on the other connecting disc 3, a plurality of connecting rods 4 are correspondingly clamped in the plurality of clamping grooves 6, and the plurality of limiting blocks 5 are respectively abutted against the connecting discs 3 with the clamping grooves 6, a plurality of joint groove 6 is along the circumference evenly distributed of connection pad 3, many connecting rod 4 is along the circumference evenly distributed of this connection pad 3 on another connection pad 3, and many connecting rods 4 and a plurality of 6 one-to-one in joint groove.

As shown in fig. 1, the inside joint hole 7 coaxial with first pipeline 1 that has opened of 1 tip of first pipeline, the outside protrusion of 2 tip of second pipeline is fixed with the joint pipe 8 coaxial with second pipeline 2, joint pipe 8 with 2 integrative taking shape of second pipeline, this joint pipe 8 switches on with second pipeline 2, and this joint pipe 8 joint is in joint hole 7, joint hole 7 is the tubaeform structure of outer end flaring, inner throat, joint pipe 8 is the tubaeform structure with joint hole 7 adaptation.

According to the arrangement mode, on one hand, the shape of the clamping hole 7 can play a good guiding role, so that medical personnel can rapidly clamp the clamping pipe 8 in the clamping hole 7 through the clamping hole 7, and rapid connection between the first pipeline 1 and the second pipeline 2 is realized;

on the other hand, when the liquid is conveyed into the first pipeline 1 through the second pipeline 2 and the clamping pipe 8, when the liquid flows through the clamping pipe 8, the liquid generates a certain lateral pressure on the circumferential inner wall of the clamping pipe 8, and the lateral pressure enables the clamping pipe 8 to be tightly abutted with the clamping hole 7 continuously, so that the liquid leakage phenomenon caused by a gap generated between the clamping pipe 8 and the clamping hole 7 is further prevented.

As shown in fig. 1, the device further comprises a first cover protection pipe 9 with an opening at one end and a second cover protection pipe 10 with an opening at one end, wherein external threads are arranged on the outer walls of the first pipeline 1 and the second pipeline 2 close to the end, the first cover protection pipe 9 is sleeved on the first pipeline 1 and is in threaded connection with the first pipeline 1, the second cover protection pipe 10 is sleeved on the second pipeline 2 and is in threaded connection with the second pipeline 2, and the first cover protection pipe 9 is abutted to the second cover protection pipe 10 to cover the limiting assembly.

Set up first cover guard tube 9 and second cover guard tube 10 can prevent effectively the junction of first pipeline 1 and second pipeline 2 receives external disturbance, prevents the junction of first pipeline 1 and second pipeline 2 receives the direct touching of external object, thereby it is further right the junction of first pipeline 1 and second pipeline 2 is protected. Be equipped with the external screw thread on the first cover pillar 9 outer wall, be equipped with the internal thread on the second cover pillar 10 inner wall, first cover pillar 9 tip is worn to establish in second cover pillar 10 and both threaded connection, will first cover pillar 9 and second cover pillar 10 carry out threaded connection, and this kind of mode can further prevent that first cover pillar 9 and second cover pillar 10 from breaking connection when receiving external disturbance to further protect the junction of first cover pillar 9 and second cover pillar 10.

As shown in fig. 1, the first and second protective tubes 9 and 10 are both transparent plastic structures, and the connection state of the joint of the first and second pipelines 1 and 2 can be conveniently observed by medical personnel, so as to further ensure the stable connection between the first and second pipelines 1 and 2.

The working principle is as follows: before dialysis treatment, medical personnel carry out the joint with the tip of first pipeline 1 tip and second pipeline 2 at first and connect, and specific process is exactly will joint pipe 8 joint is in the joint hole 7, at this moment first pipeline 1 switches on with second pipeline 2.

Afterwards, medical personnel bend each connecting rod 4 so as to enable the connecting rods 4 to be correspondingly clamped in the clamping grooves 6, and at the moment, the limiting blocks 5 at the end parts of the connecting rods 4 can be abutted to the connecting discs 3 with the clamping grooves 6.

When first pipeline 1 or second pipeline 2 receive exogenic action to first pipeline 1 produces when keeping away from the removal trend that second pipeline 2 direction removed, perhaps second pipeline 2 produces when keeping away from the removal trend that first pipeline 1 direction removed, this moment stopper 5 can both with connection pad 3 firmly butt, thereby can prevent effectively that first pipeline 1 and second pipeline 2 from deviating from and the bad phenomenon of disconnect-connection in the junction, thereby guaranteed the firm connection between first pipeline 1 and the second pipeline 2, thereby do benefit to going on smoothly of dialysis treatment.

In order to further prevent the first pipeline 1 and the second pipeline 2 from being disconnected when being subjected to external force, medical staff can respectively screw in the first cover protection pipe 9 and the second cover protection pipe 10 and enable the first cover protection pipe 9 to be in threaded connection with the second cover protection pipe 10, at the moment, the first cover protection pipe 9 and the second cover protection pipe 10 are matched to form a cover protection space, the joint of the first pipeline 1 and the second pipeline 2 can be effectively protected, and then the stable connection between the first pipeline 1 and the second pipeline 2 is thoroughly ensured.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
