Abstract

The invention discloses a medical drainage device, which comprises: bottle plug pjncture needle, air inlet device, flowing back hose, on-off regulator, screw thread mouth, the bottle plug pjncture needle pierce through the rubber bottle plug of infusion bottle or infusion bag when using, air inlet device upper end and bottle plug pjncture needle end-to-end connection, flowing back hose one end be connected with air inlet device lower extreme, on-off regulator cup joint on flowing back hose, and on-off regulator's regulating wheel extrusion flowing back hose, the screw thread mouth connect at the flowing back hose other end, the bottle plug pjncture needle adopt pjncture needle protective sheath to seal the protection when not using, the screw thread mouth adopt the screw thread mouth protective cap to seal the protection when not using. The device is not limited to an infusion bottle, can be used for an infusion bag, and can be used for puncturing once, so that the liquid medicine is prevented from being polluted by manual operation, the discharged dosage is accurately measured, and the condition of liquid leakage cannot be caused by puncturing once.

Description

Medical liquid drainage device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical drainage device.

Background

At present, an infusion bottle or an infusion bag used in a hospital is generally packaged by adopting a fixed volume, but in the actual medication process, the dosage used is often determined according to the actual condition of a patient, so related medical personnel often need to discharge redundant liquid medicine in the infusion bottle or the infusion bag, generally speaking, for the operation, a syringe is often used for pumping liquid for the infusion bottle, due to the small volume of the syringe, the operation needs to be carried out for many times, due to the operation of the personnel, the needle head is easy to cause pollution, the measurement of the discharged liquid is inaccurate, and the situation of liquid leakage can be caused by repeated puncture of a bottle stopper; and the liquid discharge needle can only be limited in bagged liquid, and the limitation is large.

Disclosure of Invention

The present invention is directed to a medical drainage device to solve the above problems.

In order to achieve the purpose, the invention provides the following technical scheme: a medical fluid drainage device comprising: bottle plug pjncture needle, air inlet device, drain hose, on-off regulator, screw thread mouth, the bottle plug pjncture needle pierce through the rubber bottle plug of infusion bottle or infusion bag when using, air inlet device upper end and bottle plug pjncture needle end-to-end connection, drain hose one end be connected with air inlet device lower extreme, on-off regulator cup joint on the drain hose, and on-off regulator's regulating wheel extrusion drain hose, the screw thread mouth connect at the drain hose other end.

Furthermore, the bottle stopper puncture needle adopts puncture needle protective sheath to seal and protect when not using.

Further, when the threaded opening is not used, the threaded opening is sealed and protected by a threaded opening protective cap.

Compared with the prior art, the invention has the beneficial effects that: when the medical liquid drainage switching device is used, when the capacity of an infusion bottle or an infusion bag is larger than the required dosage, a bottle stopper puncture needle is used for puncturing a rubber bottle stopper of the infusion bottle or the infusion bag, then a threaded opening protective cap at the tail end is opened, redundant liquid medicine is discharged, the discharged liquid medicine adopts a measuring cup to measure the dosage once, when the residual dosage is the injection dosage, a liquid drainage hose is extruded through a switch regulator, liquid drainage is stopped, the liquid drainage device is a disposable article, and after the liquid drainage device is used, the infusion device is used for normal infusion; the mode is not limited to an infusion bottle, the infusion bag can be used as well, meanwhile, only one puncture is needed, the pollution to liquid medicine caused by manual operation is avoided, the discharged dosage is accurately measured, and the condition of liquid leakage cannot be caused by one puncture.

The invention has the advantages of simple structure, convenient use, good use effect and the like.
