Description
Technical field
This utility model relates to a kind of transfusion pressurizer.
Background technology
Quick-pressing input when transfusion supercharging refers to infuse, to help the liquid such as blood, blood plasma, cardioplegia to enter as early as possible human body.At present, be directly in infusion bottle, to blow with the form of air pump to accelerating the common mode adopting of transfusion speed in infusion process, or directly transfusion bag pushed.Adopt the mode of air pump can make cannot complete transfusion in the situation that some does not possess gas source condition.In addition, the mode of directly transfusion bag being pushed is too original, and can this operation while being confined to use transfusion bag to infuse, and labor intensity is large, and through repeatedly pushing the damage that easily causes transfusion bag.Therefore, the application is devoted to solve this class problem.
Summary of the invention
The purpose of this utility model is to provide a kind of transfusion pressurizer, is simple and easy to use, and supercharging safely and effectively in infusion process, without pressure trapping, does not exist pollution.
The technical scheme that realizes above-mentioned purpose is:
A kind of transfusion pressurizer, comprises pressurized bottle, check valve, screwed union, air inlet needle conduit and air inlet needle, wherein:
Described pressurized bottle comprises the pure compressed-air actuated bottle of contain, the seal gasket that covers the bottle cap of described bottle and seal between described bottle and bottle cap; Described bottle cap center has a centre bore, and the formation one that stretches out along this centre bore edge is spigot joint; The corresponding described central hole of described seal gasket has a pore;
The entrance point of described check valve and described spigot joint connection, port of export one end by described screwed union and described air inlet needle conduit is connected, air inlet needle described in another termination of this air inlet needle conduit.
Above-mentioned transfusion pressurizer, wherein, described transfusion pressurizer also comprises that one for sealing the flow-stopping clip intermediate plate of described air inlet needle conduit.
Above-mentioned transfusion pressurizer, wherein, described pure compressed-air actuated pressure is 1.6mpa--2mpa.
Above-mentioned transfusion pressurizer, wherein, the volume of described pressurized bottle is 200ml--250ml.
The beneficial effects of the utility model are: this utility model by storing pure compressed air in pressurized bottle, utilize the pressure of gas to carrying out supercharging in infusion bottle, safe and effective, do not exist other to pollute, can completely cut off flow of infusate by the pollution of the pollutant such as airborne pathogenic bacteria.Simultaneously, this utility model is by forming a closed environment by pressurized bottle and infusion bottle, in whole process, gas pressure is stable, and air pressure minimizing meeting along with liquid in infusion bottle in infusion process is lowered gradually, and air pressure has also reduced the risk of infusion bottle bottle explosion when reduction.Meanwhile, without manually carrying out supercharging, the lifting of the efficiency that is conducive to infuse.
Brief description of the drawings
Fig. 1 is the structure chart of transfusion pressurizer of the present utility model;
Fig. 2 be in Fig. 1 A-A to position cutaway view;
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, Fig. 2 and Fig. 3, transfusion pressurizer of the present utility model, comprises pressurized bottle, check valve, screwed union 9, air inlet needle conduit 10, air inlet needle 11 and flow-stopping clip intermediate plate 12, wherein:
Pressurized bottle comprises bottle 1, bottle cap 2 and seal gasket 3, and bottle 1 storage has the pure compressed air after purification, and the volume of pressurized bottle is 200ml--250ml, and pure compressed-air actuated pressure is 1.6mpa--2mpa; Cover bottle 1 to bottle cap 2 sealings, seal gasket 3 is arranged between bottle 1 and bottle cap 2, seals; The center of bottle cap 2 has a centre bore, outwards vertically extends and to restrain one of formation spigot joint along the edge of this centre bore; The centre bore part of corresponding bottle cap 2, seal gasket 3 has a pore, to ensure compressed air circulation;
Check valve is common and is easy to the standard component product of buying.As shown in Figure 2, in the present embodiment, check valve is made up of assembly 4,5,6,7,8; The entrance point of check valve and spigot joint connection, the port of export of check valve is connected by screwed union 9 and one end of air inlet needle conduit 10, and the other end of air inlet needle conduit 10 taps into air tube 11; Certainly, above-mentioned " connection " is sealing and connects, and do not have the situation of gas leakage, air inlet.
This utility model principle:
In the time of transfusion supercharging, first by flow-stopping clip intermediate plate 12 in blind end, air inlet needle conduit 10 is sealed, then utilize air inlet needle 11 to insert in infusion bottle, open check valve, open flow-stopping clip intermediate plate 12 and make air inlet needle conduit 10 in unimpeded state, pure compressed air is continual to be passed in infusion bottle, pressure by gas is to carrying out supercharging in infusion bottle, to reach the object that increases transfusion device flow velocity.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
