Abstract

The utility model relates to a one-way fluid pressurizing sac which can press one-way fluid under the condition of requirements and causes the accelerative flow of the one-way fluid. A pipe inlet and a pipe outlet are arranged on an elastic saccule 1, and one-way valves 2 are arranged in the pipe inlet and the pipe outlet. The orientations of the two one-way valves are same. Each one-way valve 2 is composed of a hollow valve seat 21 and a valve ball 22 arranged in an inner cavity of the hollow valve seat, wherein both ends of the inner cavity of each valve seat are respectively provided with an inlet and an outlet. The inlet end of each inner cavity is provided with a concave spherical surface 23, and the center of each concave spherical surface is provided with an inlet hole. The outlet end of each inner cavity is provided with stop blocks 24 which are protruded from the outlet pipe wall and are evenly distributed. Because the utility model has the advantages of simple structure and convenient operation, the utility model is connected in series to a pipeline, the elastic saccule only needs to be pinched by a hand and pressure is generated in the sac to accelerate fluid flow rate. The utility model can satisfy special requirements, such as transfusion, drainage, etc., in clinical therapies.

Description

A kind of one-way fluid pressurized capsule

Technical field

This utility model relates to a kind of can exerting pressure to one-way fluid when needed so that it quickens mobile one-way fluid pressurized capsule.

Background technology

In routine work life, sometimes need be under the prerequisite that guarantees gas or liquid one-way flow, be interrupted or constantly according to actual needs to gas or liquid pressurization to accelerate flowing velocity, promptly to the one-way fluid pressurization to quicken.Especially in clinical medicine treatment, as treatments such as transfusion, drains, usually need according to the variation of patient and to transfusion, drain flexibly pressurization infuse or drain accelerating.Existing method has with hands extruding transfusion sebific duct or with the prelum of overcoat pushes etc. packed fluid infusion, but that the former pushes difficult effect is imprecise, and the latter can't use bottling liquid, and structure is complicated.

The utility model content

The purpose of this utility model, just provide a kind ofly be serially connected on the fluid circuit, one-way fluid pressurized capsule simple in structure, scalable, easy to use.

For achieving the above object, one-way fluid pressurized capsule of the present utility model, be one have into and out of the mouth of pipe, can restorable voluntarily resilient bladder, into and out of the mouth of pipe check valve is being housed all, two check valves towards identical.

Described check valve is made of valve seat and the valve ball that is loaded on its inner chamber, and the valve base cavity two ends have import and export, and the entrance point of inner chamber is a concave spherical surface, and import is opened in concave spherical surface, the port of export of valve base cavity be four blocks protruding from tube wall at interval.

On the basis of the above, concrete structure of the present utility model can also have other form:

Described exit end face is the interval of uniform through hole.

The beneficial effects of the utility model are: because this one-way fluid pressurized capsule is simple in structure, easy to use, wide accommodation, be serially connected in only to need behind the fluid circuit pinch and grab resilient bladder with hands, can make and produce pressure quickening rate of flow of fluid in the capsule, more can satisfy the needs in market, especially more show its superiority at aspects such as the transfusion of 15 clinical treatments, drains.

Description of drawings:

Fig. 1 is the cross-sectional schematic of one-way fluid pressurized capsule embodiment 1 structure.

Fig. 2 is the A-A line profile along Fig. 1.

Fig. 3 is the B-B line profile along Fig. 1.

Fig. 4 is a through hole enlarged diagram at interval.

Among the figure: 1 resilient bladder, 2 check valves, 21 valve seats, 22 valve balls, 23 valve seat import concave spherical surfaces, 24 blocks interval, 25 through holes are at interval.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail:

From Fig. 1 to Fig. 3, can see, one-way fluid pressurized capsule embodiment 1 of the present utility model, be one have into and out of the mouth of pipe, can restorable voluntarily resilient bladder 1, all be equipped with into and out of the mouth of pipe check valve 2, two check valves towards identical; Check valve 2 is made up of the valve seat 21 of hollow and the valve ball 22 that is loaded on its inner chamber, the valve base cavity two ends have import and export, the entrance point of valve base cavity is a concave spherical surface 23, import is opened at concave spherical surface and is hit exactly, the port of export 24 is four blocks intervals 24 of protruding from tube wall, and is simple and convenient when this can make the assembling valve ball.Present embodiment is being made of one into and out of the mouth of pipe check valve and sacculus.

After so will originally novelly being serially connected on the fluid circuit, when normal operation in normal, the fluid folk prescription flows into to the valve seat import concave spherical surface end import department from check valve, the valve ball of the check valve of import department is shifted onto on the block of the valve seat port of export by fluid, fluid flows out between the exit end face of the one-way valve seat in the same way block in exit equally from flowing between block in the capsule again; When needs one-way fluid pressurization can hands when quickening be pinched and to grab resilient bladder, make capsule inner fluid pressurized, to make the valve ball of import department's check valve be pulled to valve seat import concave spherical surface end this moment, stopped up import, fluid can not flow backwards, meanwhile the state of check valve in the same way in exit is constant, and the fluid pressurized has been accelerated flow velocity; And after sacculus was sent out, elastic sacculus restored to the original state voluntarily, produced negative pressure in capsule, exit check valve valve ball is pulled to valve seat import concave spherical surface end, stopped up the sacculus outlet, the valve ball of sacculus import department check valve recovers open state, makes the sacculus inner fluid full fast from import department.Push sacculus so repeatedly, just can reach under the prerequisite that guarantees gas or liquid one-way flow, be interrupted or constantly convection cell pressurization according to actual needs to accelerate the goal of the invention of flow velocity.

Embodiment 2 is that with the difference of example 1 port of export of check valve inner chamber is uniform communication with cavity and the interval 25 that exports through hole, sees shown in Figure 4.
