Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, a kind of specifically portable aerogenesis pressue device that power is provided for transfusion device
Background technology
At present, the transfusion device that adopts of intravenous drip has 2 kinds clinically: a kind of is the gravity suspension type, and a kind of is adding pressure type.Gravity suspension type transfusion device mainly limits to and is used for hospital, and high to the diagnosis and treatment conditional request, mobility is poor; Spatial altitude requires high, needs entourage's nurse in the clinical use, and the air of importing pollutes medicinal liquid easily or brings pathogenic bacteria into through medicinal liquid; In the use; Various patients often accumulate in the narrow and small consulting room, especially at infectious disease epidemic periods such as respiratory tracts, more are prone to cause cross infection; Be prone to when the infusion bottle suspension height is not enough simultaneously cause that serious blood refluxes; Be difficult to satisfy the fully condition of transfusion under open-air rescue and the field condition.
The adding pressure type transfusion device that uses clinically at present adopts hands squish capsule pressure transfusion more, but wastes time and energy, and needs special messenger's nurse, can't use the critical patient, pressurizes for many bottle liquid medicines continuously, and labor intensity is big, and safety is low, and inconvenience is not carried in thoroughly discharge opeing; Also the someone designs and adopts the pressurization of mechanical spring device extruding medical liquid container, complex equipments, and member is bigger, and cost is high, also is difficult for regulating and control operability and poor stability; Also the someone designs electricity consumption and accomplishes transfusion as the driven by energy motor in addition, but is having a power failure or do not having the open-air of power supply or can't use during the journey, and cost is high, and mobility is poor, poor stability, and feasibility is low, carries also inconvenient; Implement transfusion with battery driven motor, cost is high, the limited needs that can not satisfy continuous transfusion of battery capacity, and waste battery has pollution, infusion pipeline sterilization difficulty.
In present pressure transfusion process, existing transfusion pressue device often exists expense high, pressurize for medicinal liquid continuously, uses and limits to, and needs the entourage in addition, carries inconvenience, and operation sequence is complicated, can not drain situation such as medicinal liquid fully.The present invention provides a kind of have small and exquisite, safety, convenience, inexpensive, the portable heating pressure device that characteristics such as can use repeatedly; Accomplish transfusion through adjustable lasting aerogenesis pressue device for transfusion provides power, be applicable to the various requirement of infusing in the clinical treatment, as giving first aid in the field; In transit; Minimizing is accompanied and attended to, and reduces the cross infection of infectious disease epidemic period, desires out-of-bed activity or situation such as defecation and various patient body position change during transfusion; Also be a kind of instrument that prevents the respiratory tract cross infection of diagnosis and treatment place, also can be used for clinical oxygen uptake and experiment oxygen supply.
Summary of the invention
In order to solve the dynamical problem of pressure transfusion, overcome existing medical Transfusion device and carry inconvenience, pressure can not be provided continuously; Thoroughly discharge opeing, volume are bigger, and operation sequence is complicated, and costing an arm and a leg, it is difficult to wait; The present invention provides a kind of portable adjustable aerating device that supplies pressure transfusion, and it is simple in structure, and is easy to use; Power is provided can continuously and for many bottles of infusion pipelines, cheap.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of aerogenesis pressue device, it comprises: adjustable speed-changing gearcase (4), interior case (5), thorn axle A (6); Thorn axle B (7), column medicine bag (8), medicine bag band (film) (9), interior airway (10); Outer airway (11), gear shaft (12), fixed axis (13); Baffle-box (14), inner vent (12), outer vent (13) is formed.
Outer container in the device (17) is rectangular container, and chamber wall is processed by hard material, interior cogged box (4), interior case (5), baffle-box (14) and interior airway (10), the retainer ring (28) of external outer airway (11) and both sides.
Adjustable speed-changing gearcase (4) in the device links to each other with gear shaft (12); Gear shaft (12) extends forward into interior case (5); Link to each other with medicine bag band (9) through link slot; Clockwork spring (15) provides power drive gear shaft (12) rotation, causes that medicine bag band (9) is wrapped on the gear shaft (12), and through arrangements for speed regulation regulating tooth wheel shaft (12) velocity of rotation.
The relative position of gearcase (4) and interior case (5) and baffle-box (14) can be because of the material of column medicine bag (8) giving drugs into nose grain (30) and different can the change of reaction medium thing (20) in the interior case (5).
The relative position of gearcase (4) and interior case (5) and baffle-box (14) can be through following two kinds of preferred implementations:
1) Fig. 1 representes a kind of vertical optimization embodiment of apparatus of the present invention; It is characterized in that gearcase (4) is positioned at a side of outer container (17) bottom, interior case (5) is positioned at the opposite side of gearcase (4), the bottom surface of fixed axis (13), the parallel interior case (5) with gear shaft (12) of thorn axle; Outer airway (11) is perpendicular to gear shaft (12); Baffle-box (14) is positioned at the top of outer container (17), and baffle-box (14) is adjacent with gearcase (4) down, and the thorn axle is fixed on interior case (5) two side.
2) Fig. 9 representes the another kind of horizontal optimization embodiment of apparatus of the present invention; It is characterized in that baffle-box (14) and gearcase (4) are on interior case (5) top; Baffle-box (14) is adjacent with gearcase (4) left and right sides, and gear shaft (12) is perpendicular to the bottom surface of interior case (5), and outer airway (11) is parallel to gear shaft (12); Baffle-box (14) is positioned at the top of outer container (17), and the thorn axle is fixed on interior case (5) upper wall.
Medicine bag band (9) in the device can be rolled and make cylindricly, is enclosed within on the slick fixed axis (13), is made up of column medicine bag (8) and waterproofing membrane.Said column medicine bag (8) space certain distance, the rule uniform distribution is full of medicine grain (30) in the capsule, and medicine grain (30) can be made up of a certain amount of solid or liquid substance, can be solid acid (citric acid, citric acid, malic acid etc.) or solid alkali (NaHCO
3) or the mixture of solid acid and bicarbonate or the solid chemical compound (Na that other chance water can produce gas
2O
2) etc., also can be catalyst.Medicine grain (30) weight packaging in column medicine bag (8), is rolled medicine bag band (9) and processed cylindricly, can change arbitrarily or install.
Under the normal temperature and pressure, medicine bag giving drugs into nose grain (30) (like appropriate liquid environment or catalyst) under the reaction condition that interior case reaction medium thing (20) provides produces gas through chemical reaction or physical reactions.
Reaction equation: A+B====C+E ↑
A: medicine bag giving drugs into nose grain (30); B: interior case reaction medium thing (20); C: newly-generated product; E: the gas of generation is given an example:
Chemical reaction generation carbon dioxide through the puncture exposure of axle thorn, takes place and overflows column medicine bag (8) in interior case aqueous solution in the medicine grain (30) that solid acid and dry sodium bicarbonate are processed in solution.
Reaction equation is: H
++ NaHCO
3====Na
++ H
2O+CO
