Abstract
A constant-force extrusion transfusion apparatus belongs to a medical apparatus and comprises a box cover 1, a box body 2, an upper gasket 8, a lower gasket 9 and a safety locking device. It is characterized by that it has a constant-force extruding device, and is formed from elastic plate 15, spring 5, end shaft 6, roller 7 and pressure plate 4. The utility model has the most outstanding advantages of convenient operation, low price and light weight; the transfusion and blood transfusion device can be used for transfusion and blood transfusion for wounded persons in any environment, particularly indoors and outdoors in battlefields and disaster areas without hanging racks, patients can be used for transfusion and blood transfusion in standing positions, sitting positions and lying positions, particularly, the extrusion force is balanced in the initial stage, the middle stage and the ending stage in the transfusion process, the transfusion flow is stable, and the transfusion speed does not need to be adjusted.
Description
Technical field
This utility model belongs to a kind of medical apparatus, particularly a kind of fluid and blood transfusion apparatus.
Background technology
Medical treatment both at home and abroad at present still is extensive use of the suspension type infusion model, utilizes high-order pressure reduction principle transfusion and blood transfusion, and it is not too convenient to use.The report of exempting from the hanging transfusion device is also arranged, but extensively do not promoted the use of yet so far, its reason is these new techniques, and what have is too complicated, the use inconvenience that has, the weight that has is big, carry inconvenience, the expensive patient of the price that has is difficult for accepting, and particularly starting stage, interstage, the ending phase of compressive force in infusion process has difference, flow there is certain influence, needs the frequent transfusion speed of regulating.
Summary of the invention
The purpose of this utility model, it is stable remaining of infusion process just to provide a kind of compressive force, portable constant force extrusion fluid and blood transfusion apparatus.
This utility model is achieved in that it is made up of lid 1, box body 2, Upper gasket 8, lower gasket 9, safe locking device.It is characterized in that it perseveringly defeats crowded device, it is made up of elastic plate 15, spring 5, end axle 6, roller 7, increased pressure board 4.Elastic plate 15 two ends link with end axle 6, and roller 7 is sleeved on the end axle 6, can freely rotate, and the two ends of spring 5 are fixed on the end spools 6, and increased pressure board 4 and elastic plate 15 are connected at the middle part.Limiting block 20 is arranged in the box body 2, spacing to increased pressure board 4.
The most outstanding advantage of the present utility model is easy to operate, low price, do not need the energy, in light weight, the indoor and outdoor in battlefield, disaster area does not need suspension bracket to wounded's transfusion (or blood transfusion), the particularly starting stage in infusion process, interstage, the equilibrium of ending phase compressive force, infusion flow is stable, need not to regulate transfusion speed.But patient's erect-position, seat, clinostatism carry out blood transfusion and infusion, even can infuse in walking (or blood transfusion).

The specific embodiment
Box body of the present utility model is a rectangular parallelepiped, and overall dimensions can be long 26 centimetres, and wide 15 centimetres, high 8 centimetres, lid 1, box body 2 can be made with the rigid material modification of nylon.Right-hand end is hinged with hinge 11 between lid 1 and the box body 2.Upper gasket 8, lower gasket 9 can be made with elastic flexible material.The constant force extrusion unit places in the box body 2.Increased pressure board 4 and elastic plate 15 link together in the middle part.Roller 7 is enclosed within on the end axle 6, can rotate freely.Elastic plate 15 two ends are fixed on the end axle 6.The two ends of spring 5 are fixed on the end axle 6.Box body 2 has four limiting blocks, and is spacing to increased pressure board 4.Elastic plate 15 usefulness spring steel are made, and three spring 5 usefulness spring steel wires are made, two butt axles, 6 usefulness round steel are made, four rolling 7 can be made with modification of nylon.Locking device by lockhole 18, drive box button 14 and latch hook 19, safety set screw 13 and jam nut 3 are formed; Drive box button 14 and be positioned at lid left end middle part, and fuse with latch hook 19, there is spring at its rear; Nut 3 is embedded in and covers in 1, is positioned at out box button 14 rears, after safety set screw 13 screws off box button 14 can not be advanced, and has avoided collision button 14 that lid is opened, and is safer during use.When this utility model uses, will open box button 14 inwardly by, box can be opened automatically, during as transfusion, with medicinal fluid bag 12, place between elastic Upper gasket 8, the lower gasket 9, with hand lid 1 two ends, latch hook 19 inserts in the lockhole 18, and lid 1 and box body 2 are closed, and safety set screw 13 is screwed off; Tube for transfusion inserts medicinal fluid bag neck 10.The constant force extrusion is in energy accumulating state, medicinal fluid bag (or blood bag) is produced compressive force, increased pressure board 4 is in minimum point with elastic plate 15, elastic plate 15 is approximate straightened condition, and along with medicinal liquid (or blood) reduces gradually, increased pressure board 4 rises gradually with elastic plate 15, transfusion (or blood transfusion) is when finishing, increased pressure board 4 is at the highest notch with elastic plate 15, and elastic plate 15 is case of bending, as shown in Figure 1.
