Waterproof case can be made up and energy waterproof of soft material, and when pump sheet is wriggled, waterproof case is along with distortion, realThe now extruding to woven hose. Waterproof case can be membranous body.
Described waterproof case is located at the outer surface of described fore shell. Described waterproof case injection moulding in described outer surface orBonding with described outer surface.
Waterproof case also can be located at the inner surface of fore shell, if injection moulding is in inner surface or be adhered to inner surface.
When pump sheet is divided into many groups, convex closure can be multiple to having. When pump sheet does not divide into groups, convex closure can only have oneIndividual. The shape size of convex closure can design according to pump sheet. In wriggling process, pump sheet can be outwardly and energyEnough push woven hose by convex closure.
The inner surface of described fore shell is provided with around a circle of described window and compresses border, described in described matrix pressesCompress border. Matrix is pressed on and compresses on border, realizes waterproof sealing between the two, and then realizes windowThe waterproof sealing of mouth.
Described matrix is provided with locating hole, and described compression border correspondence is provided with locating dowel, and described locating hole is right with itThe locating dowel of answering coordinates.
A waterproof case for infusion pump, is made up of soft material, comprises matrix and outside from described matrix middle partThe convex closure protruding. Convex closure mates with pump sheet. Described matrix is provided with locating hole. Described matrix and convex closure one body heatMolded.
The beneficial effects of the utility model are:
1) at fore shell window place, waterproof case is set, can effectively prevents that liquid from passing through between woven hose inflow pump sheetGap, realizes the integral waterproofing of the pump housing, and can effectively reduce or avoid short circuit to cause equipment fault.
2) pump sheet when motion, the suffered amount of involving when convex closure setting can be reduced the motion of pump sheet, waterproof case simultaneouslyThe movement travel of inside and outside distortion also can reduce.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail below by detailed description of the invention.
As shown in Figures 1 to 4, a kind of infusion pump, comprise fore shell 1, the pump housing 7 and relatively fore shell openThe door 2 of closing, the pump housing 7 comprises pump sheet 11, pump sheet 11, can undulate under the driving of creeping mechanismWriggle and push woven hose 3, thereby can release gently the liquid in woven hose.
Fore shell 1 has towards the outer surface 15 of complete machine outside with towards the inner surface 16 of complete machine inside, runs through thisInner surface and outer surface are formed with window 17, and woven hose 3 is vertically located at fore shell outer surface 15, and the pump housing 7 is located atFore shell inner surface 16, and the pump sheet 11 of the pump housing can be in the time wriggling protruding this window 17 and extruding transfusionPipe 3.
Infusion pump also comprises the waterproof case 4 of being made up of soft material, and this waterproof case 4 can seal the window of fore shell17, thus can prevent that liquid from flowing to the gap between pump sheet by woven hose. Before waterproof case 4 can be located atThe inner surface of shell and between fore shell and pump sheet, waterproof case also can be located at the outer surface of fore shell.
The inner surface of fore shell can convex with around a circle of window 17 and compress border 14, and waterproof case 4 closelyBe pressed on this compression border 14, and then the window 17 of sealing fore shell.
Waterproof case 4 can comprise matrix 9 and outwardly multiple convex closures 10 in this matrix middle part certainly, convex closure 10Mate with pump sheet 11, thereby can be coated the top of pump sheet. Matrix and convex closure can integrated hot pressing formeds. ShouldThe matrix 9 of waterproof case 4 can comprise the peripheral part for locating waterproof case 4, and also comprise be positioned at multiple protrudingTransition part between two convex closures 4 of bag 4. This transition part, peripheral part and convex closure can be integral structure.Matrix 9 is pressed on fore shell 1, and transition part is posted by fore shell 1, makes coordinating of waterproof case 4 and fore shell 1Du Genggao.
As shown in Figure 1 to Figure 3, in one embodiment, infusion pump comprises fore shell 1, the pump housing 7 and waterproofPart 4. Fore shell 1 has outer surface 15 outwardly and inner surface 16 inwardly, runs through inner surface and outer surface shapeBecome window 17, fore shell is also provided with multiple erection columns 12. The pump housing 7 comprises the spaced pump sheet 11 of at least one row.Waterproof case comprises matrix 9 and multiple convex closure 10 of integrated hot pressing formed, and convex closure is positioned at the middle part of matrix outwardsProtrude, the shape size of convex closure and pump sheet is similar. Fore shell inner surface is provided with around a circle of window and compresses border14, compress border and be provided with multiple locating dowels 6, the matrix correspondence of waterproof case is provided with multiple locating holes 5.
When installation, by the cooperation of locating hole and locating dowel, waterproof case is arranged on the compression border of fore shell;Then, put into the pump housing along the direction of vertical fore shell, waterproof case is sandwiched between fore shell 1 and the pump housing 7, passes throughPump housing trip bolt 8, through pump housing installing hole 13, is locked at the pump housing on the erection column 12 of fore shell, make fore shell,The fastening one of waterproof case and the pump housing. Each convex closure of waterproof case is coated the top of the one or more pump sheets corresponding with itPortion, makes the gap of liquid between cannot inflow pump sheet 11, thereby effectively prevents that liquid from entering into equipment from the pump housing,And then avoid causing fault.
The pump housing 7 by pump housing trip bolt 8 by the compression border that is pressed on the fore shell 1 tight matrix of waterproof case 9On 14, the pump housing 7 just successfully completely cuts off water in pump housing outside by waterproof case 4 like this, and liquid cannot penetrate intoBetween pump sheet 11, thereby avoid causing the equipment faults such as short circuit.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, noCan assert that concrete enforcement of the present utility model is confined to these explanations. For technology neck under the utility modelThe those of ordinary skill in territory, without departing from the concept of the premise utility, can also make someSimple deduction or replace.
