Abstract
An ophthalmic synchronous isodose infusion-suction device belonging to the medical apparatus technical field consists of an elastic plastic bottle, a transition bottle, a one-way liquid outlet valve, a one-way air inlet valve and a double tube infusion-suction syringe needle. The infusion-suction device is characterized in that: a sealed cap which is positioned at the upper end of the elastic plastic bottle is provided with the one-way liquid outlet valve and the one-way air inlet valve respectively; the lower end of the one-way liquid outlet valve is connected with a guide tube, while the upper end is connected with the back end of the infusion tube of the double tube infusion-suction syringe needle through a hose; a sealed cap of the transition bottle is provided with two guide tubes which are respectively connected with the one-way air inlet valve arranged on the elastic plastic bottle and the back end of the infusion tube of the double tube infusion-suction syringe needle through hoses. The infusion-suction device has the advantages that: the device has a simple structure and convenient use; the liquid inside the elastic plastic bottle can be squeezed out through extruding the elastic plastic bottle, while the liquid inside an anterior chamber can be sucked into the transition bottle in the same dose through loosening the elastic plastic bottle; therefore, infusion and suction of liquid in the same dose can be carried out synchronously, which fully ensures the stability of the anterior chamber and reduces the occurrence of a complicating disease.
Description
Technical field
This utility model belongs to technical field of medical instruments, and the synchronous equivalent of specifically a kind of ophthalmic is annotated and inhaled device.
Background technology
At present, clinically in cataract operation or the anterior chamber's flush operation, usually use injection aspirator, injection aspirator relies on the height of regulating the infusion liquid transfusion bottle to regulate the amount that infusion liquid enters ophthalmic, come the negative pressure of suction Controlled needle tubing to regulate aspiration by the doctor with hands, both are asynchronous, are difficult to accomplish the synchronous equivalent of groundwater increment and aspiration, cause that easily the anterior chamber fluctuates.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of making to pour into and aspirate synchronous equivalent and finish, and guarantees that fully the anterior chamber is stable, reduces the synchronous equivalent notes of the ophthalmic suction device that complication takes place.
The purpose of this utility model is achieved in that the synchronous equivalent notes of this ophthalmic suction device is made of elastoplast bottle, transition bottle, unidirectional liquid valve, breather cheek valve, two-tube notes suction spindle head, be respectively equipped with unidirectional liquid valve and breather cheek valve on the seal cover of elastoplast bottle upper end, unidirectional liquid valve lower end is connected with conduit, and the upper end is by hose connection ascending pipe rear end at two-tube notes suction spindle head; The seal cover of transition bottle is provided with two conduits, two conduits respectively by hose connection on the elastoplast bottle breather cheek valve and the suction tube rear end of two-tube notes suction spindle head.
During use, the infusion liquid of at first in the elastoplast bottle, packing into, extruding elastoplast bottle can be expressed to infusion liquid two-tube notes suction spindle head, loosening elastoplast bottle, the elastoplast bottle produces negative pressure when restoring to the original state, by suction tube and flexible pipe above the two-tube notes suction spindle head liquid aliquot in the anterior chamber is drawn in the transition bottle, the amount of liquid that pours in the anterior chamber and discharge is equated, stablize thereby keep the anterior chamber.
Advantage of the present utility model: simple in structure, easy to use, extruding elastoplast bottle can be extruded the liquid in the elastoplast bottle, loosening elastoplast bottle can be drawn into liquid aliquot in the anterior chamber in the transition bottle, the synchronous equivalent of amount of liquid of perfusion and suction is carried out, guarantee that fully the anterior chamber is stable, reduce complication and take place.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: the synchronous equivalent of this ophthalmic is annotated the suction device and is made of elastoplast bottle 1, transition bottle 2, unidirectional liquid valve 3, breather cheek valve 4, two-tube notes suction spindle head 5, be respectively equipped with unidirectional liquid valve 3 and breather cheek valve 4 on the seal cover of elastoplast bottle 1 upper end, unidirectional liquid valve 3 lower ends are connected with conduit 6, and the upper end is by hose connection ascending pipe rear end at two-tube notes suction spindle head 5; The seal cover of transition bottle 2 is provided with two conduits, two conduits respectively by hose connection on elastoplast bottle 1 breather cheek valve 4 and the suction tube rear end of two-tube notes suction spindle head 5.
Claims (1)
1, the synchronous equivalent of a kind of ophthalmic is annotated and is inhaled device, constitute by elastoplast bottle (1), transition bottle (2), unidirectional liquid valve (3), breather cheek valve (4), two-tube notes suction spindle head (5), it is characterized in that being respectively equipped with unidirectional liquid valve (3) and breather cheek valve (4) on the seal cover of elastoplast bottle (1) upper end, unidirectional liquid valve (3) lower end is connected with conduit (6), and the upper end is by hose connection ascending pipe rear end at two-tube notes suction spindle head (5); The seal cover of transition bottle (2) is provided with two conduits, two conduits respectively by hose connection on elastoplast bottle (1) breather cheek valve (4) and the suction tube rear end of two-tube notes suction spindle head (5).
