Problems solved by technology

[0003] An infusion device is required during hemodialysis. The flow rate regulator in the existing infusion device for hemodialysis is mainly realized by squeezing the infusion hose and changing the cross-sectional area of ​​the infusion hose, such as using a clamp stopper to squeeze However, when this method is used to adjust the infusion speed, because the hose is easy to deform and stick together, it is easy to stick together after being squeezed flat, so it cannot be adjusted quickly and accurately; at the same time, the existing flow rate regulator mainly relies on human eyes Judging and grasping by observation, there is a big error, because in the process of hemodialysis, patients are more sensitive to the flow requirements of the infusion, and the traditional flow rate adjustment method cannot well meet the needs of patients

Embodiment 1

[0025] See Figure 1-3 , An infusion device for hemodialysis, comprising an infusion bag 1, an infusion tube 2 and a pillow 3, the infusion tube 2 is connected to a flow adjustment device 4 through a connector 5, the flow adjustment device 4 includes an upper cylinder 401 and The lower cylinder 402, the upper cylinder 401 and the lower cylinder 402 are rotatably connected around the central axis, the upper cylinder 401 is provided with an upper through groove 403, and the lower cylinder 402 is provided with a lower through groove. 404, the shape of the upper through groove 403 and the lower through groove 404 and the position relative to the central axis of the upper cylinder 401 and the lower cylinder 402 are the same; a groove sleeve communicating with the lower through groove 404 is connected below the lower through groove 404 405. The lower port of the groove sleeve 405 communicates with a liquid collection chamber 406; the outer circular surfaces of the upper cylinder 401 a...

Embodiment 2

[0035] In order to make the rotation between the upper cylinder 401 and the lower cylinder 402 more flexible, this embodiment is further improved on the basis of Embodiment 1. The improvement is: the lower end surface of the upper cylinder 401 is equipped with a damping slide. The upper end surface of the lower cylinder 402 is provided with a sliding groove 409 for accommodating the damping slip ring 408; when the upper cylinder 401 is rotated relative to the lower cylinder 402, the damping slip ring 408 rotates along the sliding groove 409, thereby greatly The friction in the rotation process is reduced, the rotation is more flexible, and the abrasion between the upper cylinder 401 and the lower cylinder 402 is avoided, thereby affecting the normal flow adjustment function.

[0036] The flow regulating device in the infusion device for hemodialysis is simple in structure and easy to operate. By relatively rotating the angle between the upper cylinder 401 and the lower cylinder 40...

Abstract

The invention discloses an infusion device for hemodialysis. The infusion device comprises an infusion bag, an infusion tube and a pillow; the infusion tube is connected with a flow regulating devicethrough a connector; the flow regulating device comprises an upper cylinder body and a lower cylinder body; the lower end surface of the upper cylinder body is provided with an upper through groove; the upper end surface of the lower cylinder body is provided with a lower through groove; a groove sleeve is connected under the lower part of the lower through groove; a liquid collection chamber communicates with a lower port of the groove sleeve; and scale lines and a pointer are respectively arranged on the outer circle surface of the upper cylinder body and the outer circle surface of the lower cylinder body. The flow regulating device in the transfusion device for hemodialysis is simple in structure and is convenient to operate, and through relative rotation for changing the angle betweenthe upper cylinder body and the lower cylinder body, the size of a flow channel formed by the upper through groove and inner lower through groove in the upper cylinder body and the lower cylinder body can be changed to realize regulation of the transfusion flow. Regulation precision is high, and the response speed is high. An accurate transfusion flow can be regulated according to requirements ofdifferent patients, physiological pain of the patients caused by inappropriate transfusion flow is avoided, and infusion experience of the patients is improved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion device for hemodialysis. Background technique [0002] Hemodialysis is one of the renal replacement treatments for patients with acute and chronic renal failure. It drains the blood from the body to the body through a dialyzer composed of countless hollow fibers. The blood and the dialysate containing the body's concentration are in and out of the hollow fibers. The substance exchanges through diffusion and convection to clear the body. Metabolize waste, maintain electrolyte and acid-base balance; at the same time, remove excess water in the body and return the purified blood. [0003] An infusion device is needed during hemodialysis. The flow rate regulator in the existing infusion device for hemodialysis is mainly achieved by squeezing the infusion hose and changing the cross-sectional area of ​​the infusion hose, such as using a clamp stopper. However, when th...
