Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings, this utility model is introduced in detail, it will be appreciated that simply introduce this reality below
By novel detailed description of the invention, and do not lie in restriction protection domain of the present utility model.
As Figure 1-4, a kind of can the drainage bag of accurate flow adjustment, including drainage bag body 1 and drainage bag body 1
First discharging tube 2 of lower section connection, delicate flow actuator the 3, second discharging tube 4 and the intermediate plate 5 being set on discharging tube, drain
Bag body 1 has scale, and described delicate flow actuator 3 has the liquid-inlet 31 being arranged on above delicate flow actuator 3
With the liquid outlet 35 being arranged on below delicate flow actuator 3, described first discharging tube 2 connects with liquid-inlet 31, described
Liquid outlet 32 connects with the second discharging tube 4, and described second discharging tube 4 liquid outlet has protection set 6.Discharging tube increases essence
Close flow regulator, and also it is provided with intermediate plate, intermediate plate and the flow velocity of delicate flow actuator equal scalable liquid, more just
Just, protection set and it is provided with on the liquid outlet of discharging tube, it is ensured that drainage bag is not contaminated.
Described delicate flow actuator 3 includes that upper cover 32, lower cover 33 and rubber cushion 34, described liquid-inlet 31 are arranged on upper cover
On 32, described liquid outlet 35 is arranged on lower cover 33, and described upper cover 32 and lower cover 33 are circular lid coaxially connected, described
Rubber cushion 34 is for annular and has micropore 341, and is fixed on lower cover 33, and described micropore 341 is arranged on directly over liquid outlet 35
Connecting with liquid outlet 35, the bottom surface of described upper cover 32 has inner sealing annular protrusion 321, outer closure annular protrusion 322, arranges
Between inner sealing annular protrusion 321 and outer closure annular protrusion 322 semiclosed protruding 323, described semiclosed protruding 323
Starting point is liquid-inlet end, and the terminal of semiclosed annular protrusion 323 exists certain distance, upper cover 32 and lower cover away from liquid-inlet end
During 33 connection, above-mentioned protruding 321 and 322 and 323 withstand rubber cushion 34.The flow velocity of liquid is relevant with damping, damps the biggest, liquid
Flow velocity is the least, and, the flow distance that liquid flow damping coefficient in small gap is generally large, the most small, flow value
Will have greatly changed, inner sealing annular protrusion and outer closure annular protrusion prop up rubber cushion, and inner sealing annular protrusion is with outer
The passage that liquid flows through it is formed between closed ring projection, when liquid-inlet alignment liquid exports, the maximum flow of liquid,
When rotating relative to lower cover along with upper cover, liquid-inlet is slowly away from liquid outlet, and the distance that flows through of liquid slowly becomes big, therefore
Flow can be more and more less, and arranges semiclosed projection, and runner is layered two small flow channels, and the damping of medicinal liquid can be bigger, effect
Become apparent from.
The lateral surface on described lower cover 33 top has first annular protruding 331, and the medial surface of described upper cover 32 is provided with
Second ring projection 324, the second annular protrusion 324 and upper cover 32 bottom surface are formed with the first annular cannelure of protruding 331 of receiving
325, when upper cover 32 is connected with lower cover 33, first annular protruding 331 are placed in cannelure 325, in order to first annular projection exists
Rotate in cannelure.First annular projection is stuck in cannelure, thereby ensure that upper cover can only rotate relative to lower cover, and can not make
Upper cover departs from lower cover.
Described upper cover 32 has flow scale 326 and for limiting upper cover 32 and lower cover 33 limited block in relative rotation
327, described lower cover 33 is correspondingly arranged on flow pointer 332.Nurse can carry out, according to flow scale, the stream that accurate observation is per minute
Speed is how many, and the setting of limited block, can limit the angle that upper cover rotates relative to lower cover, in case spin-ended degree of turning over and lead
Cause flow suddenlys change, and time during rotation to certain angle, limited block withstands flow pointer, upper cover and lower cover and the most further rotates.
Described upper cover 32 and lower cover 33 are provided with some accordion projections 10.Accordion projection is possible to prevent allowing upper cover
Skidding when rotating against with lower cover.
Described lower cover 33 has the circular trough 328 accommodating described rubber cushion, has some alignment pins in described circular trough 328
329, described rubber cushion 34 is fixed in circular trough 328 by alignment pin 329, to prevent the outlet displacement of micropore relative liquid.
Described liquid-inlet 31 and liquid outlet 35 are circular port.
Embodiment of the present utility model simply introduces its detailed description of the invention, does not lies in and limits its protection domain.The industry
Technical staff under the inspiration of the present embodiment, may be made that some is revised, therefore all done according to this utility model the scope of the claims
Equivalence change or modification, belong in this utility model scope of the patent claims.
