Abstract
The utility model discloses a disposable continuous lumbar cistern drainage device. The disposable continuous lumbar cistern drainage device comprises a drainage tube body. The disposable continuous lumbar cistern drainage device is characterized in that the head end of a connecting tube enters the subarachnoid space through a puncture needle, the puncture needle is withdrawn, the tail end of the connecting tube is closely connected with a transparent drainage tube through a screw connector, the drainage tube is connected with a tee joint through a catheter by means of the screw connector, the tee joint is connected with a flow regulator through the catheter, a dripping bucket is installed between the tee joint and the flow regulator, and the flow regulator is connected with a drainage bottle through the catheter. According to the disposable continuous lumbar cistern drainage device, a tube can be dredged upwards or downwards or medicine can be injected without the need to divide the drainage tube, the probability of inflection is reduced, the drainage speed can be adjusted accurately, manual counting and conversion are not needed, and time and energy of medical staff are saved.
Description
Technical field
The utility model relates to medical instruments, especially disposable Lumbar continous drainage device.
Background technology
Lumbar continous drainage art is in the primary treatment process of a lot of diseases of neurosurgery, and its utilization is very extensive.At present, the Lumbar continous drainage device adopting is clinically formed by article transformations such as disposable anesthetic puncture bag, disposable transfusion device and drainage bottle or drainage bags mostly.Through drainage tube intrathecal injection medicine or dredging drainage tube, when it is kept clear, need breakout to connect drainage tube, repeatedly expose drainage tube joint, increased the probability infecting; General infusion set control valve does not have exact scale, can not accurately control drainage speed, and artificial counting drips the fast work that is converted into again flow and also expended a large amount of time and the energy of medical worker simultaneously.
Summary of the invention
The problem existing for above-mentioned prior art, this utility model provides a kind of disposable lumbar cistern drainage device, and this device does not need that separately drainage tube just can make progress, downward dredging pipeline or injectable drug, has reduced the probability of infection; All right fine adjustment drainage speed, does not need artificial counting and conversion, has saved medical personnel's time and energy.
To achieve these goals, the technical solution adopted in the utility model is: disposable Lumbar continous drainage device, is comprised of puncture needle, connection tube and drainage tube.Feature of the present utility model is that connection tube 2 head ends enter subarachnoid space through puncture needle, returns puncture needle 1, and connection tube 2 ends are closely connected with transparent drainage tube through screw joint 3; Described drainage tube is to pass through catheter connecting tee device 4 by screw joint 3, and three-way device 4 is by catheter connection traffic actuator 6; Separately between three-way device 4 and flow regulator 6, dropping funnel 5 is housed; Flow regulator 6 connects drainage bottle 7 by catheter.
This programme by three-way device realize upwards, dredging pipeline, infused drug and leave and take cerebrospinal fluid cultivation etc. downwards, and needn't separate drainage tube, avoided the direct exposure of drainage tube interface, reduced the probability that alien bacteria infects.
This programme is realized accurate flow adjustment by flow regulator, needn't artificial counting drain drips speed and is converted into flow again, has guaranteed the accuracy of drainage speed, has saved medical personnel's energy and the time.
In this programme, drainage tube interface all adopts screw joint, connects more firmly, and airtight performance is better, there will not be de-pipe and leakage.
In this programme, drainage bottle adopts and is inverted triangle, guarantees that metering drainage liquid total amount is more accurate; Drainage bottle is designed with anti-anti-backflow device, can reduce drainage-fluid retrograde infection probability; Drainage bottle lower end is designed with the liquid joint of releasing, and facilitates medical personnel to topple over drainage-fluid.
The beneficial effects of the utility model are: the disposable lumbar cistern drainage device of design realized upwards, dredging pipeline, infused drug and leave and take cerebrospinal fluid cultivation etc. downwards, can fine adjustment drainage speed and accurate measurement drain total amount, and be provided with anti-reflux device, reduced the probability infecting, saved medical personnel's energy and time, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structure chart that this utility model is implemented;
In figure: 1 puncture needle, 2 connection tubes, 3 screw joints, 4 three-way devices, 5 dropping funnels, 6 flow regulators, 7 drainage bottles.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.This utility model is that puncture needle 1, connection tube 2 and transparent drainage tube main body form.Drainage tube main body consists of jointly screw joint 3, three-way device 4, dropping funnel 5, flow regulator 6 and drainage bottle 7.Connection tube 2 head ends enter subarachnoid space through puncture needle, return puncture needle 1, and connection tube 2 ends are closely connected with transparent drainage tube through screw joint 3, and screw socket connects more firmly more airtight; Screw joint 3 is by catheter connecting tee device 4, and three-way device 4 is used for upwards, dredging pipeline, infused drug and leave and take cerebrospinal fluid cultivation etc. downwards; Three-way device 4 connects dropping funnel 5 by catheter, and whether dropping funnel 5 is unobstructed for observing drain; Dropping funnel 5 is by catheter connection traffic actuator 6, and flow regulator 6 is used for fine adjustment drain flow, thereby accurately controls drainage speed; Flow regulator 6 connects drainage bottle 7 by catheter, and drainage bottle 7 is designed to be inverted triangle and is provided with anti-anti-backflow device, guarantees that metering drainage liquid total amount is more accurate on the one hand, can reduce on the other hand drainage-fluid retrograde infection probability.
