Abstract
The utility model relates to a medical simple one-way valve and comprises an inflow tube, a male casing, a rubber diaphragm, a female casing and an outlet tube. An end of the male casing is provided with an opening and the other end is sealed with an the inflow tube; an end of the female casing is provided with an opening and the other end is sealed with the outlet tube; the opening end of the male casing is connected with the opening end of the female casing, between which is formed with a cavity; the rubber diaphragm is arranged in the cavity between the male casing and the female casing. The utility model has simple structure, and can ensure that the fluid flows along the same direction and cannot flow back.
Description
Technical field
This utility model is a kind of medical simple and easy fluid one-way cock.
Background technology
In clinical position, often run into the situation that needs to extract intravital liquid of people or gas.During extraction, enter in the body, in clinical manipulation, generally adopt a fluid one-way cock, guarantee that fluid can only and then can not backflow before a direction in order not allow the liquid extracted out or gas reflux again.The present commercially available many complex structures of fluid one-way cock, price is more expensive, so we have designed this medical simple and easy fluid one-way cock.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, allow the fluid can only be before a direction and then the easy device that can not backflow.
This utility model comprises valve body, inflow pipe, effuser and places the intravital rubber membrane of valve that valve body is made up of public shell and female shell, public shell one end opening, end sealing and the middle inflow pipe that is provided with; Female shell is long slightly, an end opening, end sealing and the middle effuser that is provided with, female shell shell wall is thicker near the sealed end place, and thinner near open end, the opening internal diameter is consistent with public shell external diameter, public shell aperture end is connected with female shell aperture end, between formation one cavity.Inflow pipe is longer, with public shell close adhesion be one, an end exposes outside the public shell, the other end stretches in the public shell and is concordant with public shell aperture plane; Effuser is short slightly, and being positioned at the outer also end of female shell and female body seal end close adhesion is one; The nearly periphery of rubber membrane has aperture, places between public shell and the female shell.Public shell and female shell can be drums, also can be other shapes; Rubber membrane can be the disk shape, also can be and corresponding other shapes of male and female shell, and the edge on the diaphragm circumferentially is provided with aperture, and little number of perforations is not limit, generally can be uniform six.
This utility model can guarantee effectively that liquid or gas can only be entered by inflow pipe, flows out by effuser then, and can reverse flow.This utility model is not only simple in structure, and low price, and except that rubber membrane, other parts all can adopt transparent plastic to do material.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the installation diagram of this utility model embodiment.
Among the figure, the 1st, inflow pipe, the 2nd, public shell, the 3rd, rubber membrane, the 4th, female shell, the 5th, effuser.
The specific embodiment
As shown in Figure 1, present embodiment comprises valve body, inflow pipe 1, effuser 5 and rubber membrane, and wherein valve body is formed by being public shell 2 cylindraceous and female shell 4, and rubber membrane 3 is the disk shape, and nearly periphery has six apertures.Earlier rubber membrane 3 is placed on the opening and the perimeter alignment of public shell 2, then female shell 4 openings are enclosed within outside the public shell 2, rubber membrane 3 is tightly squeezed between the male and female shell, and the tight connection of male and female shell can be adopted the bonding or spiral of binding agent, after finishing as shown in Figure 2.
