Description

Hemodialysis pipeline flow maintaining clamp

Technical Field

The utility model relates to a hemodialysis equipment technical field specifically is hemodialysis pipeline flow maintenance clamp.

Background

Hemodialysis is a commonly used blood purification technology, which utilizes the principle of semipermeable membrane to achieve the purposes of purifying blood and correcting water electrolyte and acid-base balance by diffusing and removing various harmful and redundant metabolic wastes and excessive electrolytes in the body.

Before hemodialysis operation, a punctured pipeline needs to be sealed, generally operated by a clamp, but when the clamp needs to be opened by releasing the seal, the pipeline is in a clamped state due to long-time clamping of the clamp, blood flow is influenced after the machine is operated, and the machine frequently gives an alarm. Based on this, the utility model designs a hemodialysis way flow volume maintains and presss from both sides to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hemodialysis way flow maintains and presss from both sides to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above purpose, the utility model provides a following technical scheme: the blood permeation pipeline flow maintaining clamp comprises a clamping sleeve, wherein the clamping sleeve is respectively arranged on an A pipe and a V pipe of the blood permeation pipeline, the pipeline blocks flow during clamping, the clamping sleeve comprises a flexible sleeve body, a hollow cavity is formed in the sleeve body, an inlet communicated with the hollow cavity is formed in one side of the sleeve body, arc-shaped walls which are gradually arched towards the center are arranged on two sides of the inner wall of the hollow cavity in the clamping sleeve, the outer portion of the clamping sleeve is pressurized through a clamp, and the clamping sleeve deforms and extrudes the A pipe and/or the V pipe through the arc-shaped walls, so that the arc-shaped walls block flow of the pipeline.

Preferably, the hollow cavity is eccentrically arranged on the sleeve body.

Preferably, the jacket is made of flexible PVC medical material.

Preferably, the arc of the arcuate wall extends from an upper end to a lower end of the jacket.

Preferably, a circle of positioning groove is formed in the middle of the surface of the sleeve body, and the clamping position of the clamp is located in the positioning groove.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up and press from both sides the cover, and the inner wall both sides in the hollow chamber in inside that presss from both sides the cover are equipped with the arc wall that arches gradually to the inner center, carry out the centre gripping through the clip to pressing from both sides the cover, the arc wall is because it has great radian, make the clip when the application of force of pipeline centre gripping, have great contact surface with the pipeline, and lifting surface area increases, the sealing effect when one of which increases and seals, its two, can not persist the indentation when removing and seal, the pipeline can not have the shrivelled state, can not arouse because the machine that the blood flow is obstructed reports to the police that causes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: hemodialysis pipeline flow maintains and presss from both sides, including pressing from both sides cover 3, press from both sides cover 3 to set up respectively on hemodialysis pipeline's A pipe 1 and V pipe 2, and A pipe 1 and V pipe 2 are used for doing internal fistula hemodialysis pipe, and on its end still inserted the dialysis machine, need seal A pipe 1 and V pipe 2 before operating the computer after the puncture, so carry out the pipeline choked flow when the centre gripping through pressing from both sides cover 3.

The jacket 3 comprises a flexible jacket body 31, and the jacket 3 is made of flexible PVC medical material and can deform under the action of clamping force. A hollow cavity 32 is arranged in the jacket body 31, an inlet 33 communicated with the hollow cavity 32 is formed in one side of the jacket body 31, arc-shaped walls 34 which are gradually arched towards the inner center are arranged on two sides of the inner wall of the hollow cavity 32 in the jacket 3, and the radian of the arc-shaped walls 34 extends from the upper end to the lower end of the jacket 3; press from both sides cover 3 outside through clip 4 and pressurize, press from both sides cover 3 deformation and extrude A pipe 1 and/or V pipe 2 through arc wall 34, make arc wall 34 carry out the choked flow to the pipeline, when clip 4 pressurizes, the most inboard of arc wall 34 is at first extrudees the pipeline at first, along with the pressurized going on, the area of contact of pipeline and arc wall 34 increases thereupon, it is closed until the pipeline is extruded completely to arc wall 34, when needs contact pipeline choked flow, loosen clip 4, it resets to press from both sides cover 3 deformation, the pipeline also resets to deform, it is great to pipeline outer wall extrusion area when pressing from both sides cover 3's arc wall 34 choked flow, make can not leave the indentation when the pipeline resets, do not influence its normal circulation.

The hollow cavity 32 is eccentrically arranged on the sleeve body 31, and the eccentric arrangement has the effect that when the clip 4 is taken off, the wall thickness of one side of the sleeve body 31 is larger, so that the sleeve body 31 has better resetting capability.

Wherein, the surperficial intermediate position of the cover body 31 has seted up round constant head tank 35, and the clamping position of clip 4 is in constant head tank 35 for to the location of clip 4, keep clip 4 can accurately carry out the centre gripping in the assigned position.
