Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention.

The utility model provides a hemodialysis machine structure with improve feed tube is as shown in fig. 3, its most structure is the same with the dialysis machine in the past, namely, be provided with warning light 1 at equipment main part top equally, the front portion is provided with preceding control panel 2, heparin pump 3, blood pump 4, room 9 is listened to the air, return circuit presss from both sides 10, be provided with the bracing piece at equipment main part side, the bracing piece middle part is equipped with artifical kidney support 8, the top is equipped with gallows 7, lower part position left side is provided with artifical kidney connection entry 11 in equipment main part, export 12 is connected to artifical kidney, the right side is provided with washing connector A5, wash connector B6. The specific arrangement of these components and their connections are disclosed in the prior art and are not described in the present application.

The difference is that the support 13 and the central feed port A, B no longer need to be provided on the machine side. The liquid supply tube a18 and the liquid supply tube B19 both adopt a three-way structure, taking the liquid supply tube a as an example, as shown in fig. 4, the liquid supply tube a includes a flushing insertion tube a01, an internal connection tube a02 and a central liquid supply tube a03, the three pipelines are communicated through a three-way connector a04, the flushing insertion tube a01 is inserted into the flushing connector a5, the internal connection tube a02 is connected into the machine, and the central liquid supply tube a03 is directly connected to the liquid supply center. Control elements are arranged on the flushing cannula A01 and the central liquid supply tube A03 respectively. The control element can adopt an element which is easy to operate, such as a clamp or a valve, and can respectively control the opening and the closing of two passages of the flushing intubation tube A01 and the connecting tube A02 in the machine. The liquid supply pipe B has the same structure as the liquid supply pipe A.

In this example, the control element is a clip 17 as shown in fig. 5, and includes a fixed portion 1701 and a movable portion 1702 which are oppositely arranged, the fixed portion and the movable portion are connected by an arc-shaped connecting section 1703, a first protrusion 1704 is arranged in the middle of the fixed portion 1701, a second protrusion 1705 is arranged in the middle of the movable portion, the first protrusion 1704 and the second protrusion 1705 are oppositely arranged, and a hook 1706 is arranged at the tail of the fixed portion. The arc connecting section is arranged to enable the clamp to keep good elasticity, and operation is convenient. When the clip is operated, the thumb and forefinger respectively pinch the fixed part 1701 and the movable part 1702, and force is applied to the tail of the movable part to press the tail of the movable part into the hook, so that the first projection 1704 and the second projection 1705 are adjacent to each other, as shown in fig. 6, and only a small gap is formed in the middle, and in this state, the passage of the flushing cannula A01 or the passage of the connecting tube A02 in the gap is closed. When the passage needs to be opened, the tail part of the fixed part of the clamp is pushed away in the direction away from the movable part, and the tail part of the movable part is pulled out from the clamping hook. As shown in fig. 7, the top (arc-shaped connecting section) and the bottom (fixing portion tail) of the clip are provided with through holes 1707 through which the liquid supply tube can pass, so that the clip does not fall off even when it is not necessary to clamp the tube.

The liquid supply pipes A and B in the hemodialysis machine with the improved liquid supply pipes do not need to be opened at the middle threaded port and then connected with a central liquid supply pipeline. When the dialysis machine is in a standby and disinfection state, the clamp arranged on the central liquid supply pipe A03 is closed, the clamp arranged on the flushing insertion pipe A01 is opened, at the moment, the passage from the dialysis machine to the two flushing connecting ports is unblocked, a disinfection flushing loop is formed on the dialysis machine, and no passage exists between the disinfection flushing loop and the central liquid supply end. When dialysis is needed, the clamp arranged on the flushing cannula A01 is closed, the clamp arranged on the central liquid supply pipe A03 is opened, and at the moment, dialysate enters the dialyzer through a passage formed by the central liquid supply pipe A03 and the machine connecting pipe A02 and does not flow into the two flushing connecting ports.

In this example, the dongli hemodialysis machine is taken as an example, and the above-described modified structure can be applied to another hemodialysis machine of the same type having the flushing connection port a and the flushing connection port B.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
