Abstract
The utility model relates to a disposable transfusion pressure device which consists of a gasbag, single valves, a tee valve, an air filtering valve and a tube. The gasbag has elasticity, one single valve is provided with a valve while the other single valve is provided with an underlying lacuna, the middle of the tube is provided with the tee valve, and the inside of the tube cavity is provided with the air filtering valve. The utility model makes the pressing transfusion operation simple, convenient and highly effective, reduces the exogenetic infection on the basis of not influence the gravity transfusion. The utility model has simple structure and is easy for proceeding and producing.
Description
The disposable infusion prelum belongs to medical apparatus and instruments.
At present, the vein pressure transfusion does not have special apparatus, is used alternatingly mosquito forceps by two nurses usually and clamps the exhaustor of transfusion device and use syringe gas injection repeatedly.The pressure transfusion complicated operation, workload is big, and increases exogenous infection.
The purpose of this utility model provides a kind of disposable infusion prelum, on the basis that does not influence the gravity transfusion, makes pressure transfusion easy and simple to handle, and high efficiency reduces exogenous infection.
The purpose of this utility model is achieved in that elastic bag made by polyethylene, and respectively there is a check valve at two ends, and wherein an end is connected with flexible pipe, and the exhaustor by flexible pipe and transfusion device links to each other.Owing to take such scheme, make the pressure transfusion simple and effective, reduce the exogenous infection chance.The disposable infusion prelum is simple in structure, is easy to processing.
Description of drawings:
Fig. 1 is a disposable infusion prelum sketch map
Fig. 2 is a check valve A sketch map
Fig. 3 is a check valve B sketch map
The potential lacuna 5. air bag 6.1. flap valves of 1. flexible pipes, 2. air filtration valves, 3. three-way valve, 4. check valve B 4.1. among the figure
Form with embodiment is illustrated below: in the drawings, air bag (5) has elasticity, and an end has a flap valve (6.1), and flap valve is closed during extruding gasbag, and air bag makes flap valve open by elastical retraction.The other end of air bag has check valve B (4), is the column flexible plastic, and there is a potential lacuna (4.1) at the center, usually be in closure state, gas is washed open and by potential lacuna, check valve B is connected with flexible pipe (1) during extruding gasbag, there is three-way valve (3) in the flexible pipe stage casing, and the flexible pipe intracavity has air strainer valve (2).Because the effect of two check valves and a three-way valve, check valve A closes when extruding gasbag, and check valve B is open, and the air in the air bag enters in the infusion bottle by check valve B, three-way valve and air filtration valve.When air bag was not extruded, by the elastic return shape, this moment, check valve A was open, and check valve B closes, the air admission air bag.When gravity was infused, air entered in the infusion bottle through three-way valve and air filtration valve.
The disposable infusion prelum is all made by the no-toxicity medical macromolecular material.
