Description

Non-dismantling irrigator connecting pipe

Technical Field

The utility model relates to an exempt from to tear open and remove perfusion ware connecting pipe belongs to hemodialysis medical equipment field.

Background

Hemoperfusion is a blood purification treatment means for adsorbing and removing toxic metabolites by an adsorbent in an perfusion device. The resin hemoperfusion apparatus is usually connected with a hemodialyzer in series for use in clinic, so as to remove the medium-macromolecule toxin in the body of a renal failure hemodialysis patient. Hemodialysis is generally four hours, and the dialysis time through the hemoperfusion apparatus is two hours, so that the hemoperfusion series hemodialysis is performed in the first two hours of blood purification, and the dialysis access needs to be replaced after two hours.

Currently, during clinical treatment, access changes are achieved by manually removing the hemoperfusion cartridge. Therefore, in the process of removing the perfusion apparatus, the tightness of the blood path tube cannot be ensured, the operation is complicated, blood and body fluid overflow can occur, even large-area splashing can cause pollution, and the risks of blood coagulation, air embolism and blood pollution are increased. In addition, the blood in the perfusion device is flushed back to the body of the patient, the pipeline connected with the tube flushing liquid is far away from the perfusion device, the liquid filling amount is required to be large, about 200ml, and the liquid capacity in the body of the patient is increased.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: how to ensure the tightness of the blood path tube under the condition of changing the path of the blood perfusion device.

In order to solve the technical problem, the technical scheme of the utility model is to provide a non-dismantling perfusion device connecting pipe, which comprises a perfusion device, wherein two ends of the perfusion device are respectively connected with one end of a first connecting pipe and one end of a conduit, and the other end of the first connecting pipe is connected with one end of an arterial blood external connecting pipe; switches are respectively arranged on the second connecting pipe, the first connecting pipe and the guide pipe; the switch on the catheter is positioned between the connection part of the second connecting pipe and the catheter and the perfusion apparatus; the first connecting pipe is communicated with the three-way connector, and the connecting position of the three-way connector and the three-way connector is positioned between the switch on the first connecting pipe and the perfusion apparatus.

Preferably, a switch is respectively arranged at the port positions of two ends of the second connecting pipe.

Preferably, the switch is a clip; the first connecting pipe, the second connecting pipe and the conduit are hoses.

Compared with the prior art, the utility model has the advantages that:

the utility model discloses an exempt from to tear open and remove perfusion ware connecting pipe realizes the change of pipeline through opening and closing that sets up connecting pipe, three way connection ware, first clip, second clip, third clip, fourth clip, need not to demolish the perfusion ware, can solve clinical hemodialysis process's actual problem. The three-way connector is arranged at the inlet section of the perfusion apparatus, so that the liquid amount required by blood return is reduced, and the volume load of a hemodialysis patient is reduced.

The utility model discloses can alleviate the hemodialysis in-process medical personnel operation degree of difficulty, security height, simplify the operation flow, reduce the risk of infecting, get into the risk emergence of adverse events such as the internal liquid volume of patient, air embolism when reducing the flushing pipe.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model provides an exempt from to demolish perfusion ware connecting pipe, as shown in fig. 1, it includes perfusion ware 1, the entrance point of perfusion ware 1 bottom links to each other with 2 one ends of first connecting pipe, accompany first clip 4 on the first connecting pipe 2, first clip 4 is used for controlling the intercommunication state of first connecting pipe 2, first connecting pipe 2 is located position and three way connection ware 3 switch-on between first clip 4 and the perfusion ware 1, the other end and the arterial blood outer tube 5 of first connecting pipe 2 are linked together, lie in position and the entry end switch-on of second connecting pipe 7 between arterial blood outer tube 5 and the first clip 4 on the first connecting pipe 2, the position that is close to its entry end on the second connecting pipe 7 accompanies second clip 6, the position that is close to its exit end on the second connecting pipe 7 accompanies third clip 8. The second clip 6 and the third clip 8 are used to control the passage of the second connection pipe 7. The outlet end of the top of the perfusion device 1 is connected with one end of a conduit 9, the other end of the conduit 9 is the outlet end of a vascular access, the outlet end of a second connecting pipe 7 is communicated with the middle position of the conduit 9, and a fourth clamp 10 is clamped between the outlet end of the second connecting pipe 7 and the perfusion device 1 on the conduit 9. The first clip 4 and the fourth clip 10 are used to control the passage between the infuser 1 and the first connecting tube 2 and between the infuser 1 and the conduit 9, respectively.
