Description
This utility model relates to a kind of medical apparatus and instruments, especially a kind of liquid suction device.
In present clinical use, to the most general drawing liquid apparatus of Celom liquid loading by puncture needle, how to form with rubber tube, empty needle and mosquito forceps, puncture needle links to each other with empty needle by rubber tube, puncture needle inserts the position that needs drawing liquid, the negative pressure that the pin utilization produces of finding time charges in the needle tubing liquid, uses mosquito forceps that rubber tube is clamped when needs stop drawing liquid.In use there are many shortcomings in this device: at first open connection between each one, sealing is not enough between the position, secondly it can only observe the drawing liquid amount with the empty needle high scale merely, degree of accuracy is low, the empty needle repetitive operation is wasted time and energy in addition, the tapping function also can only be operated and measure with empty needle, and operation contacts with air and is easy to influence the quality that extracts liquid.
The purpose of this utility model provides a kind of convenient and reliable, pumping device that degree of accuracy is high.
The technical scheme of taking for this utility model that achieves the above object is as follows:
A kind of quantitative pumping device, it comprises puncture needle and flexible pipe, be characterized in: it also comprises medical control valve, three way cock and the negative pressure ball of volumetric flask, restriction tapping speed, volumetric flask is made of bottle stopper and the transparent graduated bottle that has, bottle stopper sealing bottleneck, the bottom of bottle side wall have one with the bottle chamber communicate and into a single integrated structure pipe joint, be plugged with the flexible pipe of emitting liquid on the pipe joint, be with medical control valve on the flexible pipe; Have two vertical feedings in the volumetric flask and with bottle stopper to constitute integrally-built feed tube and exhaust tube on the bottle stopper, the end that feed tube stretches out outside bottle connects the flexible pipe that has puncture needle, is with medical control valve on the flexible pipe; The end that exhaust tube stretches out to bottle top is connected with flexible pipe, and the other end of flexible pipe is connected with negative pressure ball, is serially connected with the three way cock on flexible pipe, and three way cock's side connector upper joint sleeve has the flexible pipe of medical control valve, and the connecting portion in this device is airtight connection.
External part also should be long than exhaust tube external part in bottle in bottle for above-mentioned quantitative pumping device, feed tube, but feed tube external part port position in bottle answers the maximum scale line position on the specific volume measuring bottle to exceed.
Because taked the structure of negative pressure ball and threeway to make suction time saving and energy saving, also very convenient to liquid measure control, in addition, the use of volumetric flask has improved the precision of adopting liquid measure.
Below in conjunction with embodiment and accompanying drawing this utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of bottle stopper 6 among Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Among the figure: 1, puncture needle 2, flexible pipe 3, medical control valve 4, feed tube 5, volumetric flask 6, bottle stopper 7, flexible pipe 8, three way cock 9, flexible pipe 10, negative pressure ball 11, medical control valve 12, exhaust tube 13, pipe joint 14, flexible pipe 15, medical control valve
Embodiment shown in Figure 1 is made of puncture needle 1, transparent flexible pipe 2,7,9,14 and volumetric flask 5, medical control valve 3,11,15 and three way cock 8 and negative pressure ball 10, volumetric flask 5 is made of bottle stopper 6 and the graduated transparent bottle of band 200ml, the base position at the close bottle of the bottle side wall end has the pipe joint 13 with the sidewall one, and pipe joint 13 connects and composes the tapping passage with the flexible pipe 14 that is with medical control valve 15; Bottle stopper 6 and bottle good seal, have on the bottle stopper 6 two ends stretch out bottle stopper and and the feed tube 4 of the circle of bottle stopper 6 one and exhaust tube 12 (as Fig. 2, shown in 3), wherein feed tube 4 external part in bottle is longer, exhaust tube 12 external part in bottle is shorter, even but feed tube 4 external part port in bottle can not be lower than the position of the maximum scale line on the bottle, this is because when two-port position that feed tube 4 and exhaust tube 12 stretch out in bottle too closely the time, can produce Extract directly is inhaled into exhaust tube 12 from feed tube 4 situation, if and feed tube 4 ports are lower than maximum scale line on the bottle, will finish the collection of maximum scale capacity so; One end on 4 bottles of tops of drain pipe is connected with the flexible pipe 2 of band puncture needle 1, is with medical control valve 3 on the flexible pipe 2.One end on 12 bottles of tops of exhaust tube is by flexible pipe 7 and 10 airtight connections of negative pressure ball, be serially connected with Y shape three way cock 8 on the flexible pipe 7, Y shape three way cock 8 main termination links to each other with exhaust tube 12, a pipe port of three way cock 8 links to each other with a flexible pipe 9 with medical control valve 11, flexible pipe 9 emptyings, make it become relief passage, another pipe end of three way cock 8 links to each other with negative pressure ball 10.
During use the drawing liquid position is desired in puncture needle 1 insertion, medical control valve 3 is opened, medical control valve 11, medical control valve 15 are closed, thereby pinching negative pressure ball 10 is extracted liquid out and is entered volumetric flask 5 then, when desiring to stop liquid collecting, medical control valve 3 can be closed, or medical control valve 11 opened the elimination negative pressure, or both are used.When desiring tapping, medical control valve 3 must be closed, medical control valve 11, medical control valve 15 are opened simultaneously and are got final product.Above-described medical control valve is the control valve that is enclosed within on the transfusion device flexible pipe.
This utility model is easy to operate, the high advantage of meter liquid degree of accuracy with more embodying if the part of this utility model except that negative pressure ball made disposable product, and can also prevent that the liquid that this covering device extracts from being polluted, and can also prevent cross infection.
