Has the characteristics of reasonable structure, dual purposes, flexible and convenient clinical use, relatively low treatment cost of patients and the like. However, the above solution also has the following disadvantages: above-mentioned scheme is used the clip to press from both sides tight pipeline, prevents that the waste liquid in the collection bag from flowing out, but at the in-process of transportation and depositing, if the collection bag receives the extrusion, the waste liquid can strut the clip and flow out from the pipeline, causes the pollution.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hemodialysis's waste liquid collection bag to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bag is collected to waste liquid of hemodialysis, includes the waste liquid bag, the lower extreme of waste liquid bag is connected with the pipe, the lower extreme of pipe is connected with plug-in connection, plug-in connection includes the casing, the middle part of casing is equipped with annular arch, bellied middle part sliding connection has the pipe that runs through, the right-hand member fixed mounting of pipe has the valve plug, be equipped with rectangular hole on the lateral wall of pipe, the left end fixed mounting of pipe has the plectane, be connected with the spring between plectane and the arch, the inner chamber left end fixed mounting of casing has the plug bush.

Preferably, the upper side of the waste liquid bag is provided with a hanging lug, and the hanging lug is provided with a waist circular hole.

Preferably, the circular plate is connected with the inner cavity of the shell in a sliding mode, a round hole communicated with the inner cavity of the guide pipe is formed in the middle of the circular plate, and the spring is sleeved on the guide pipe.

Preferably, the plug bush is formed by injection molding of PP plastic, and the inner end of the plug bush is provided with a necking down.

Preferably, the inner cavity of the shell is fixedly connected with an annular sealing ring, and the sealing ring is positioned between the plug bush and the circular plate.

Compared with the prior art, the beneficial effects of the utility model are that: this collection bag is when the switch-on, and the pipeline inserts and pushes up the plectane inwards from the plug bush, and the pipe removes and makes the rectangular hole on it cross the arch, and bellied both sides are switched on to the waste liquid can get into the waste liquid bag through the pipe, and after extracting the pipeline, the spring drives the valve plug and resets and carries out the shutoff with protruding contact, prevents that the waste liquid from flowing. This collection bag can be quick by the switch-on and can be quick sealed, convenient to use, the waste liquid can't be crowded to open the valve plug and flows to safe firm.
