Abstract

The utility model discloses a medical liquid shunting apparatus for sucking and injecting, being composed of a main body and an injector nipple connecting port. Two parallel tube cavities are arranged in the main body, an air valve type one-way movable valve is fixed in each tube cavity, the directions of the two valves are opposite, two tube cavities are united at the injector nipple connecting port at one end of the main body, and the other end respectively connects and communicates with two drainage hoses, and the free ends of the two drainage hoses are connected with injection needle nipples. The shunting apparatus which has the advantages of simple structure and convenient usage connects the two medical processes of sucking and injecting as a whole.

Description

Medical liquid shunting apparatus for aspiration and injection

This utility model relates to a kind of manual sowing, fertilising instrument, especially a kind of portable sowing, fertilizer applicator.

At present rural area, farm sow the seed in spring, the fertilising instrument has multiplely, a kind of on the large tracts of land soil, is to operate with machine tool mostly as farm or contract entered into by an individual soil upper seeding wheel, fertilising, efficient height like this, saving of labor, laborsaving; Another kind is in the mountain region or when splat sowing, fertilising, carry out with hand sowing kind, fertilization mode mostly, but operating efficiency is low by hand, takes a lot of work, requires great effort, and particularly sows, applies fertilizer and can not carry out simultaneously.

The purpose of this utility model provides a kind of portable sowing, fertilizer applicator.

The utility model is achieved like this: on funnel bottom, have roller, has the roller fixed axis in the middle part of the right of roller end face and roller is connected as a single entity, middle part at the left side of roller end face has the roller movable axis, the roller fixed axis, the middle part through hole of the axle ear that the roller movable axis is connected with funnel the right and left bottom respectively connects, at inboard middle respectively have the draw spring of roller the right and left end face with the axle ear, draw an end of spring to be connected with roller, the other end is connected with the axle ear, it is corresponding with the funnel bottom that middle part the right and left on the roll surface of the top of roller has half garden connected in star respectively, having draw ring on roll surface behind the roller middle part is connected with draw ring cover lower end, the upper end of draw ring cover is connected with the stay cord lower end, the upper end of stay cord is connected with the depression bar left end, has pressure shaft and handle left end on the depression bar left side and flexibly connects.

During use, seed, fertilizer are respectively charged into about dividing plate in two casings, the funnel, because being up/down perforations, casing and funnel be connected as a single entity, with the hand depression bar once, roller 180 degree that roll forward, seed, fertilizer in the groove of the half garden shape of packing into are sowed simultaneously, when depression bar unclamps, draw spring action on the roller rest, roller is returned turnback in the other direction

Advantage of the present utility model: simple in structure, easy to use, will aspirate, inject two processes and become one, simplified the medical care precess process, alleviated patient's misery.

Accompanying drawing is medical use liquid suction, injection turn of tidal stream device structure chart:

Among the figure: (1) syringe nipple interface; (2) turn of tidal stream device main body; (3) air gate type one-way movable valve; (4) main body tube chamber; (5) drain flexible pipe; (6) entry needle joint.

Below in conjunction with drawings and Examples this utility model is described.

Syringe nipple interface (1) is connected with syringe, and during syringe pump, liquid enters in the syringe by the air gate type check valve (3) that a side drain flexible pipe (5) is attached thereto, and aspiration can intuitively show by syringe graduation; When injecting operation, the liquid in the syringe is discharged by coupled logical homonymy drainage tube by another air gate type one-way movable valve, so far finishes liquid turn of tidal stream process.

Claims

A kind of medical use liquid suction, injection turn of tidal stream device, form by turn of tidal stream device main body and syringe nipple interface, it is characterized in that: have in the main body two consistent with its major axis and be the parallel tube chamber of axis of symmetry with the major axis, each fixes an air gate type one-way movable valve in each tube chamber, two valve directions alive are opposite, and at an end of main body, two tube chambers meet at the syringe nipple interface, the other end is connected with two drain flexible pipes respectively, and two flexible pipe free-ends are connected with the entry needle nipple.
