The jet flow no-dead-space water supply module comprises a jet flow pipe (1), the upper end and the lower end of the jet flow pipe (1) are of the same diameter, the diameter of the jet flow pipe narrows down from both ends to the middle, the narrowest middle of jet flow pipe is provided with a jet flow nozzle (11), both ends of the jet flow pipe (1) are provided with connector (2), and the upper portion and the lower portion of the jet flow pipe (1) are symmetrically provided with a first branch pipe port (12) and a second branch pipe port (13) which are perpendicular to the jet flow pipe, wherein the first branch pipe port (12) and the second branch pipe port (13) are connected with hoses (4) through connecting plug (3), the remote ends of the hoses (4) are connected with the first inlet (51) and the second inlet (53) of a three-way plug (5), and the outlet (52) of the three-way plug (5) is connected with a quick plug (6). The jet flow no-dead-space water supply module generates negative pressure in pipes according to the jet flow principles to enable water supply pipes to generate branch circulation, thereby having no dead space during the whole process, avoiding bacteria breeding and being high sanitary standard.

Description

Jet supplies water assembly without dead space

Technical field

This utility model belongs to medical apparatus and instruments articles for use field, especially refers to supply water assembly for what supply water to Hemodialysis instrument without dead space.

Background technology

At present, hemodialysis is as a kind of the most frequently used acute or chronic renal failure kidneys of patients Replacement Therapy, its required water system is also most important, but existing Hemodialysis supplies water, design concept is simple, only have systemic circulation, part is that dead angle, sterilization are not thorough everywhere, the sterilization of dead angle part less than, disinfect weak effect, bacteria breed is serious.

Utility model content

For addressing the above problem, this utility model provides a kind of jet to supply water assembly without dead space, produces negative pressure by jet current principle in pipeline, makes supply channel produce shunting circulation, omnidistance without dead space, not breed bacteria, and sanitary index is high.

For achieving the above object, this utility model adopts following technical scheme:

A kind of jet supplies water assembly without dead space, comprise jet pipe 1, described jet pipe Shang Xia 1 two ends caliber identical, described jet pipe caliber is narrowed to middle part gradually by pipe ends, the narrowest place, middle part is jet orifice 11, jet pipe 1 two ends have union joint 2, at described jet pipe 1 upper semisection and the first shunting mouth of pipe 12 that is symmetrical arranged vertical described jet pipe on lower semisection, the second shunting mouth of pipe 13, the described first shunting mouth of pipe 12, the second shunting mouth of pipe 13 is by connecting pin 3 connecting hose 4 respectively, the first import 51 of connecting tee plug 5 respectively of described flexible pipe 4 far-ends, the second import 53, the outlet 52 of described three-way plug 5 connects fast patch plug 6.

Wherein, be symmetrical arranged the first shunting mouth of pipe 12, the second shunting mouth of pipe 13 of vertical described jet pipe in described jet pipe 1 upper semisection central authorities and lower semisection central authorities.

The beneficial effects of the utility model are: the object of the invention is to provide a kind of brand-new way of supplying water, design concept is from the past completely different, hemodialysis water system increases again partial circulating in systemic circulation, effect stability, use simple, safety, reliable, can effectively use dead space part not exist, real circulation is got up, and life cycle reaches more than 10 years, and effect reaches and prevents that bacteria breed from arriving the best.

Brief description of the drawings

Fig. 2 is the embodiment of the present utility model great circulation system structure chart that supplies water.

Number in the figure: 1-jet pipe 11-jet orifice 2-union joint 12-first shunts mouth of pipe 13-second and shunts the quick plug of mouth of pipe 3-connecting pin 4-flexible pipe 5-three-way plug 51-first import 53-the second import 52-outlet 6-.

Detailed description of the invention

Following examples are only for this utility model example is clearly described, and the not restriction to embodiment of the present utility model.For those of ordinary skill in the field; on the basis of following explanation, can also make other multi-form variation or variations, and these belong to apparent variation that this utility model spirit draws or variation still among protection domain of the present utility model.

As Fig. 1, shown in 2, in figure, arrow is depicted as water (flow) direction, a kind of jet of the present utility model supplies water assembly without dead space, comprise jet pipe 1, described jet pipe Shang Xia 1 two ends caliber identical, caliber is narrowed to middle part gradually by pipe ends, the narrowest place, middle part is jet orifice 11, jet pipe 1 two ends have union joint 2, two union joints 2 are connected this assembly with main-supply, be symmetrical arranged the first shunting mouth of pipe 12 of vertical described jet pipe in described jet pipe 1 upper semisection central authorities and lower semisection central authorities, the second shunting mouth of pipe 13, the described first shunting mouth of pipe 12, the second shunting mouth of pipe 13 is by connecting pin 3 connecting hose 4 respectively, two imports 51 of connecting tee plug 5 respectively of described flexible pipe 4 far-ends, the outlet 52 of described three-way plug 5 connects fast patch plug 6, described quick plug 6 connects haemodialysis control unit, described quick plug 6 has function of self closing.Other position away from jet orifice both sides also can be selected in the position of the described first shunting mouth of pipe 12, the second shunting mouth of pipe 13, as long as this assembly can produce water circulation.

Operation principle of the present utility model is as follows, the water of main-supply is entered in jet pipe 1 by the upper end of jet pipe 1, first during through the first shunting mouth of pipe 12, water is divided into two circuits, article one, enter haemodialysis control unit through the first import 51, outlet 52, the quick plug 6 of the first shunting mouth of pipe 12, flexible pipe 4, three-way plug 5, water, through the second import 53 of three-way plug 5, is led to the second shunting mouth of pipe 13 through connected flexible pipe 4 simultaneously, another of water circuit is through jet orifice 11, because the two ends caliber of jet pipe 1 is wider, and the first shunting mouth of pipe 12, the second shunting mouth of pipe 13 is all arranged on the wider place of caliber of jet pipe 1, in the time that water is passed through the jet orifice 11 of jet pipe 1 caliber minimum, because the caliber of jet orifice 11 is narrow, form the tiny water column of spurting through the water of jet orifice 11, tiny water column forms negative pressure when through the second shunting mouth of pipe 13 with from the second shunting mouth of pipe 13 water out, between the first shunting mouth of pipe 12 and the second shunting mouth of pipe 13, also form negative pressure, the water column being penetrated by jet orifice 11 is not refluxed from the second shunting mouth of pipe 13, but converge from jet pipe 1 lower end and flow away with the second shunting mouth of pipe 13 water out, thereby the water that makes the first shunting mouth of pipe 12 flow to the second shunting mouth of pipe 13 can form lasting one-way flow, when carrying out systemic circulation, whole water system carries out partial circulating in distribution pipeline simultaneously, local without dead space, not breed bacteria.

As shown in Figure 2, jet of the present utility model replaces point water distribution manifold assembly in Hospitals at Present hemodialysis water system without dead space for water assembly, the jet pipe of multiple assemblies is connected in the systemic circulation pipeline of whole system, supply water respectively to the haemodialysis control unit of each sick bed, this assembly material can be UPVC, CPVC, PPH, the materials such as SUS304 rustless steel, the modular constructions such as above-mentioned connecting pin 3, three-way plug 5 and connected mode are prior art, therefore repeat no more.
