Abstract

The utility model discloses a pressure type transfusion device, and belongs to the field of medical appliances. A transfusion bottle with an upward bottle mouth of the pressure type transfusion device is placed in a bottle sleeve, and the tip of an air outlet pipe of an air pressing capsule is inserted into the upper part of the inner cavity of a medicine bottle from the bottle cap; the other end of a transfusion tube with a syringe needle is connected with a segment of rigid tube with a tip, and the rigid tube is inserted into the bottom of the medicine bottle from the bottle cap; the diameter of the bottom of the inner cavity of the transfusion bottle is gradually decreased from top to bottom; the bottom outside of the transfusion bottle is provided with a tail-fin-shaped supporting foot; and the bottle sleeve of the transfusion bottle comprises three layers of bottle sleeves, namely a large bottle sleeve, a medium bottle sleeve and a small bottle sleeve, for respectively holding large, medium and small medicine bottles, and large and small annular slings are arranged on each bottle sleeve. The pressure type transfusion device realizes transfusion by air pressure; a patient does not need to lift the medicine bottle while going to the toilet, so that the hands can be released to make certain action; the pressure type transfusion device can be hung on a hanger after air pressure in the medicine bottle is cleared so as to realize transfusion by gravity; and the pressure type transfusion device is suitable for various transfusion states.

Description

The vapour-pressure type infusion set

Technical field: this utility model belongs to medical instruments field, particularly a kind of infusion set.

Background technology: existing infusion set is that infusion bottle is hung on drip stand, leans on the deadweight of medicinal liquid to flow downward, and through syringe needle medicinal liquid is imported in the patient's blood vessel.Patient during the transfusion needs other people and helps to lift high medicine bottle if will go to toilet, and patient activity is inconvenient, does not note slightly also blood back taking place.Patent " the self-service infusion set of wear-type " provides a kind of infusion bottle to be placed on the transfusion apparatus in the headgear, can make the patient not rely on other people, and safe ready infuses whenever and wherever possible.But weak point is also arranged, increased load on the head, cause discomfort, particularly headache, dizzy patient is more inapplicable.Simultaneously also limited patient activity, caused medicine bottle to drop easily and have an accident.

Summary of the invention: the purpose of this utility model is a kind of vapour-pressure type infusion set of design, through the air pressure that increases in the medicine bottle medicinal liquid is imported human body, need not medicine bottle be placed eminence, and it is movable not limit the person, does not have the significant discomfort sensation.For realizing this goal, adopted following technical scheme: the vapour-pressure type infusion set, form by transfusion medicine bottle, tube for transfusion and bottle cover.Bottleneck transfusion bottle up is placed in the bottle cover, and the tip of the capsular escape pipe of calming the anger inserts medicine bottle inner chamber top from bottle cap; The other end that has the tube for transfusion of injection needle has connector, and this connector connects one section acuminous hard tube, and this hard tube inserts the medicine bottle bottom from bottle cap.The diameter of infusion bottle intracavity bottom dwindles from the top down gradually; The bottom of infusion bottle outside has tail-like feet.The bottle of infusion bottle overlaps and comprises that the big bottle cover that can put large, medium and small three kinds of medicine bottles respectively, middle bottle cover, bottle overlap three layers, and bottle has put two ring-type suspender belts of size.

The vapour-pressure type infusion set is infused by gas pressure, need not when patient goes to toilet to hold medicine bottle high, can free hand to do some actions.Also can hang over medicine bottle on the suspension bracket, be applicable to various transfusion states, convenience is provided to patient and nurse.

Description of drawings: Fig. 1 is the structural representation of vapour-pressure type infusion set.Fig. 2 is the structural representation of bottle cover in the vapour-pressure type infusion set.Fig. 3 is the structural representation when tube for transfusion is reduced into the supporting state of existing conventional infusion bottle in the vapour-pressure type infusion set.

Specific embodiments: be further described below in conjunction with accompanying drawing.

As shown in Figure 1, bottleneck infusion bottle 4 up is placed in the bottle cover 3, and escape pipe 1 tip of the capsule 2 of calming the anger inserts bottle inner chamber top from bottle cap.Have the tube for transfusion 7 of injection needle, its other end has connector 8, and this connector connects one section acuminous hard tube 5, and this hard tube inserts the bottle bottom from bottle cap, can select the hard tube of different length for use to the large, medium and small various medicine bottle that different amount of liquid medicine are housed.The diameter of infusion bottle intracavity bottom dwindles gradually from the top down and is point end shape, so that medicinal liquid is concentrated in the bottom.The bottom of infusion bottle outside has tail-like feet 6, is convenient to the stable placement of medicine bottle.Infusion set in use can be given medicine bottle air pressure slightly with pressurised airbag by patient or nurse, through observing the liquid droping speed of tube for transfusion, regulates the transfusion speed with flow valve again.When medicine bottle hangs over when infusing on the suspension bracket, just passable through the pressure that the valve of pressurised airbag is removed in the medicine bottle.As shown in Figure 2, the bottle cover of infusion bottle comprises that big bottle cover 3, middle bottle cover 9, the bottle that can put large, medium and small three kinds of medicine bottles respectively overlap 10 3 layers: and large, medium and small three kinds of medicine bottles are selected a ground and are contained in and are fit in own bottle overlaps.Bottle has put two ring-type suspender belts of size, with little ring suspender belt medicine bottle is hung on the suspension bracket when patient infuses in bed; When going to toilet, patient medicine bottle is hung over the front with the macro ring suspender belt.As shown in Figure 3, down the time, the connector 8 on the tube for transfusion also can connect existing tube for transfusion plug 11 at routine transfusion Chinese medicine bottleneck.
