Description

Disposable multifunction transfusion system

This utility model relates to a kind of medical Transfusion device, especially a kind of disposable multifunction transfusion system.

In clinical and open-air rescue, transfusion fast usually needs to pressurize, normally with the large syringe gas injection of directly pressurizeing in the infusion bottle, the shortcoming of this pressure transfusion mode is: inject gas in the infusion bottle through filtration, liquid easily is not suspended in airborne pathogenic bacteria or particle contamination, in addition because the air cavity of infusion bottle is very little, storage to pressure is limited, so that the pressure in the infusion bottle is difficult to constantly and lasting, usually needs the repetition gas injection, not only very bother, but also can increase opportunities for contamination.Gaoqing medical devices head factory (No. 13, Qinghe road, Gaoqing county town, Shandong Province in recent years, fax: 0533-9663808, phone: 0533-9662670) produced a kind of disposable transfusion device, because the gas outlet of vertical that Infusion bottle lid perforator inlet channel of its dropper is positioned in the liquid of infusion bottle bottleneck, therefore the liquid in the infusion bottle can outwards trickle from the air inlet of Infusion bottle lid perforator inlet channel when pressure transfusion.On July 13rd, 2000, Yangcheng Evening News the 11 edition was a headline with " air has been imported in transfusion ", with " Hong Kong one old woman dies from operating-table because of malpractice danger " be that subhead has reported that of Hong Kong public hospital generation causes air embolism with the transfusion bag pressure transfusion, cause the case of patient's left hand paralysis binocular half-blindness, Hong Kong is a modern international metropolis, and the transfusion device that manifested of this case structurally has defective.Author Xu Yuhua likes that with me caprice serves as to inscribe in invention and change to have delivered one piece of short essay on the new magazine, call can have a kind of transfusion safety shutoff come out early (see invention and change the 28th page of new 2000 the 2nd phase) to the greatest extent, delivering of this article shows that there is above-mentioned defective equally in present homemade transfusion device.In addition, some patient (as the child) or some disease (as heart failure) or some drugs (as pituitrin) have strict demand to drip velocity, and the drop of general infusion set big (20/ml), its accurate adjustment transfusion is difficulty comparatively, China's nursing magazine has been delivered one piece of paper that exercise question is " development of disposable velocity modulation control multipurpose transfusion device " for the 74th page in 2000 the 35th volumes, in fact this transfusion device be common water dropper intracavity increase adorned a draw point micro drop head (100/ml), its scope of application is still wide inadequately, still can not satisfy the needs of multiple transfusion.

The purpose of this utility model provides a kind of quick transfusion of pressurization, meticulous adjusting transfusion and microdroplet not only can stablized and infuses, and the disposable multifunction transfusion system that the transfusion device passage can be closed automatically when terminal phase of intravenous injection.

For reaching above-mentioned purpose, the technical solution of the utility model is: described dropper is the fowl claw type, there is an elastic force storage pressure bag type transfusion pressue device on described dropper top, have two mutually different water droppers of specification on the roof of described Murphy's burette at least, the intracavity of described Murphy's burette has a terminal phase of intravenous injection self closing device.

As further improvement of the utility model, described elastic force storage pressure bag type transfusion pressue device is interconnected to constitute by a four-way connecting pipe and flow-stop valve thereof, double-layer elastic reservoir pressure capsule, the pneumatic whistle of level pressure formula relief valve and switch, an inflatable ball (or gas tube) and an Infusion bottle lid perforator.

As further improvement of the utility model, an air filter is arranged on the air inlet of described Infusion bottle lid perforator inlet channel, the air cavity of the gas outlet of this inlet channel and infusion bottle bottom directly connects, and the inlet of described Infusion bottle lid perforator liquid outlet channel is positioned at the bottleneck of infusion bottle.

As further improvement of the utility model, a common water dropper, a meticulous adjusting water dropper and a microdroplet water dropper are arranged on the roof of described Murphy's burette, the diameter of the cross section of wherein meticulous adjusting water dropper inner chamber is shorter than the diameter of the cross section of common water dropper inner chamber, the diameter of the cross section of its microdroplet water dropper inner chamber is shorter than the diameter of the cross section of meticulous adjusting water dropper inner chamber, and respectively there is a flow-stopping clip top of these three water droppers.

As further improvement of the utility model, described Murphy's burette is cone-shaped, and that terminal phase of intravenous injection self closing device of described Murphy's burette intracavity is interconnected to constitute by the membranaceous shutoff of ball float, floating ball rod and Murphy's burette liquid outlet.

Further improve as of the present utility model, described membranaceous shutoff is made by flexible material, the shape of described membranaceous shutoff bottom surface and the shape of Murphy's burette inner chamber diapire are suitable, and respectively there is a belt tank top of overlooking membranaceous shutoff and Murphy's burette inner chamber diapire.

This utility model is compared with the disposable transfusion device of prior art has following advantage: because an elastic force storage pressure bag type transfusion pressue device and air filter are arranged on the transfusion device, when pressurization is infused fast, not only the trouble that can avoid the repeated puncture gas injection to be brought can also prevent repeated puncture and directly bring potential microgranule or pathogen contamination toward the interior gas injection of infusion bottle; Owing on the Murphy's burette roof water dropper of three different sizes is arranged again, thereby can more conveniently regulate drip velocity exactly; Because the Murphy's burette intracavity has a terminal phase of intravenous injection self closing device, fundamentally eliminated the danger of air embolism in addition; Also pressue device has comparatively stable pressurization usefulness because elastic force storage pressure bag type is infused, and not only is fit to clinical pressurization and infuses fast, the especially suitable open-air rescue and the middle transfusion use of advancing.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
