Abstract

The utility model relates to an automatic pressurizing device for first-aid infusion, which is composed of a transparent air duct, an elastic clip and an automatic pressurization device, wherein the front part of the transparent air duct is a steel needle and the rear part is provided with an air filter net and a tail joint; the elastic clip closes an air inlet duct of a disposable infusion unit; the automatic pressurization device is composed of a cylindrical rigid container, a piston, a spring, a pull rod, a front cover and a back cover. The automatic pressurization device can quantitatively carry out timing and quantitative pressurization and exhaust in different levels, which infuses the quantified physic liquor quickly within the timing range, obtaining the purpose of clinical emergency treatment. The utility model can automatically stop pressurizing after the physic liquor transfusion is finished, and thus no redundant air is infused.

Description

The first aid automatic prelum of infusing

This utility model " first aid infuse automatic prelum " belongs to medical apparatus and instruments, relates generally to clinical critical patient when rescuing medication, needs transfusion fast and a kind of medical apparatus and instruments of invention.

At present clinical in to critical patient's rescue process, will infuse fast the time (as the application of cerebral hemorrhage patient mannitol, shock patient need be injected normal saline, the low right side etc.), generally all be two kinds of medications, a kind of is intravenous injection again after with the 50-100ML syringe medicinal liquid being extracted out; Another kind is the air inlet pipe of clamping disposable transfusion device with mosquito forceps, and reuse 20-30ML syringe injects air in medicine bottle, to increase the pressure in the medicine bottle medicinal liquid is imported fast.These two kinds of methods are covered end: (1) is time-consuming, has increased medical personnel's working strength.(2) medicinal liquid pollutes easily, and the infusion reaction chance is increased.(3) medicine liquid leakage is serious.It is clinical to also have a kind of infusion pump can be used at present, but the expense costliness increases the weight of patient's financial burden.

The purpose of this utility model is to provide a kind of first aid of being convenient to operate automatic prelum of infusing, and it is low, simple to operate that it has a cost, and can be at regular time and quantity, the disposable use of airway, no repeated contamination, the characteristics that can match with all types of disposable liquid devices and use.

In order to finish above-mentioned purpose, concrete technical scheme is as follows:

First aid infuse automatic prelum by the transparent airway of belt lacing, elastic force folder and automatically pressue device form, transparent airway front portion is a hollow draw point, its end has an airstrainer and an afterbody joint, and it is connected with the papillary joint of automatic pressue device front end.The elastic force folder can clamp and cut out the air inlet pipe of disposable transfusion device.

Automatically pressue device is a molten device of garden tubbiness hard, and its inner wall smooth is neat, and the container front end stretches out and dwindles as the bottleneck shape, there is the helical form screw thread of projection its outside, have a lid can swivelling cover on, there is a papillary joint in lid central authorities, it can link to each other with the afterbody joint of airway and press.The rear portion of container is a big opening such as grade, and there is the helical form screw thread of projection its outside, has again on the lid swivelling cover, and there is an oblong openings in lid central authorities.Be used to pass pitch brace, there is a piston rigid container inside, and piston is connected with rotating pull bar.Three pairs of concave indentation are arranged on the pull bar, so that be stuck in the position of fixed piston on the bonnet, the end of pull bar has a handle for nurse operation, on pull bar, be with a spring, one a crown is on bonnet regularly on the piston, and the elastic force of spring promotes piston forward automatically and moves, play liquid pressurization by emptying gas, and reach the purpose of quick transfusion.Automatically the deflated volume of pressue device is 125ML, 250ML, three class of 500ML, the scale sign is arranged on container, the tensile strength of spring has certain regulation, having arranged 125ML air required time is 10-15 minute, promptly having arranged the time of 250ML air will finish in 20-30 minute, and having arranged 500ML air required time is 30-40 minute.

This first aid is infused automatic prelum compared with prior art, and it is low, simple to operate to have a cost, and no medicine liquid leakage at regular time and quantity, is imported in the body medicine fast, and do not have air admission behind the medicine of being totally lost, thereby reaches the characteristics of first aid purpose.

Below in conjunction with the embodiment accompanying drawing, this application is described in further detail:

As shown in Figure 1,1-3 is the transparent airway of belt lacing among the embodiment, and 1 is hollow steel needle.2 is airstrainer.3 is the afterbody joint.Transparent airway ethane via epoxyethane or the disposable use of cobalt 60 sterilization back sealings.As shown in Figure 2,4 are the elastic force folder, can clamp and close the air inlet pipe of one-time infusion tube.As shown in Figure 3, Figure 4,5-17 is automatic pressue device among the embodiment, 7 is a garden tubbiness rigid container that transparent inner wall smooth is neat, its front end dwindles as the bottleneck shape, there is the helical form screw thread of projection the outside, lid 6 rotatable the covering of a band papillary joint 5 are arranged, and joint 5 can be connected with the airway end.The afterbody of container is an opening that grade is big, and there is thread button of spiral of projection the outside, and a lid 16 rotatable covering are arranged, and there is a rectangular opening 15 in the central authorities of lid 16, and the pull bar 11 of cuboid passes from this opening.It (is that exhaust volume is decided to be 125ML that container is marked with volume scale 8,250ML, three class of 500ML), internal tank has a piston 9 to contact closely with container inner wall, a cuboid pull bar 11 and handle 17 are arranged behind the piston, pull bar 11 can make piston 9 front and back activities, and when pull bar 11 rotates and piston 9 does not rotate, concave indentation 12 is arranged on the pull bar 11,13,14, when pull bar is moved piston to the 125ML position, breach 14 promptly arrives the position of back cover gab 15, when pull bar is moved piston to the 250ML position, breach 12 promptly arrives the position of back cover gab 15, when pull bar is moved piston to the 500ML position, breach 13 promptly arrives the position of back cover gab 15, but rotating rod fixed piston position.10 1 on spring is fixed on the piston rear, and a crown is on bonnet 16, and pull bar 11 passes in the middle of spring 10.The tensile strength of spring 10 has certain requirement, promptly automatically elastic force arranged the required time separate provision of 125ML, 250ML, 500ML gas 10-15 minute, 20-30 minute, 30-40 minute.After transparent airway connects, rotating tension bar handle once more, spring promotes the piston automatic vent, gas pressurized is injected the medicinal liquid bottle, medicinal liquid is imported in the body fast, and i.e. pressurization stops automatically behind be totally lost automatically 125ML, 250ML, the 500ML liquid, does not have in the air input body.

This first aid automatic prelum material therefor of infusing all meets national medical standard.
