Abstract
The utility model relates to alumbar drainage device with fluid reflux prevention capacity. The drainage device comprises a drainage bag onto which a tube body is connected, a water stop piece and a Luer taper arranged on the drainage bag tube body, a drainage tube as well as a connecting piece connected with one end of the drainage tube. The drainage device is characterized in that the connecting piece comprises a body and a connecting pipe with one end inserted into the body, the end, inserted into the body, of the connecting pipe is sleeved with a medical plastic drum membrane, one end of the medical plastic drum membrane is fixedly connected with the connecting pipe, and the other end adopts a closed duck bill shape. The lumbar drainage device with the fluid reflux prevention capacity has the advantages as follows: when the drainage device is adopted for cerebrospinal fluid puncture drainage, cerebrospinal fluid reflux can be prevented, infection brought by the cerebrospinal fluid reflux is avoided, and the surgical risk is reduced; and further, use of a drainage bottle device can be avoided, surgical operation of a medical worker is facilitated, and the manufacturing cost of the drainage device is reduced.
Description
Technical field
This utility model belongs to clinical medicine apparatus, particularly relates to a kind of lumbar cistern drainage device that prevents liquid countercurrent.
Background technology
Lumbar cistern drainage is neurosurgery treatment blood contained cerebrospinal fluid or a kind of conventional treatment operation of infecting the diseases such as cerebrospinal fluid, can be used for dredging ventricular system, the generation of prevention hydrocephalus, reduces intracranial pressure, alleviates headache and treatment intracranial infection.At present, the Lumbar continous drainage device that clinical medicine is used comprises the puncture drainage assembly that consists of puncture needle, guide wire, drainage catheter, liner conduit and female Luer, conduit, liquid-collection bag etc., during use, by guide wire, insert drainage catheter, liner conduit is arranged in drainage catheter tube chamber, female Luer one end is connected with drainage catheter end, and the other end is connected with supravasal joint, and liquid-collection bag is communicated with drainage catheter by conduit.But if any careless manipulation, the situation that there will be cerebrospinal fluid to reflux, and then the hidden danger of generation intracranial infection.In order to prevent that cerebrospinal fluid from refluxing, all use the drainage system with drainage bottle, add drainage bottle not only increased product cost, to cause Yao great Chi to hold stream apparatus structure complicated; And bring inconvenience to medical personnel's operation.
Summary of the invention
This utility model provides a kind of simple in structure, lumbar cistern drainage device of reducing manufacturing cost and easy and simple to handle prevented liquid countercurrent for solving the technical problem existing in known technology.
The technical scheme that this utility model is taked for the technical problem existing in solution known technology is:
Can prevent the lumbar cistern drainage device of liquid countercurrent, comprise the drainage bag that is connected with body on it, be arranged on water on drainage bag body only with female Luer, drainage tube and the connector that is connected with drainage tube one end, it is characterized in that: described connector comprises that body and one end insert intrinsic connection tube, described connection tube inserts intrinsic one end outer cover medical plastic bucket film is housed, described medical plastic bucket film one end and connection tube are affixed, and the other end is duckbilled closed form.
This utility model can also adopt following technical scheme:
Described connector body shaft is upwards shaped with symmetrically and the wing being connected as a single entity with it.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, during use, when cerebrospinal fluid forward passes through medical plastic bucket film, cerebrospinal fluid normally flows out; During cerebrospinal fluid reverse flow, the pressure that is subject to cerebrospinal fluid due to medical plastic bucket film, in closure state, cannot reflux liquid, and then realizes the function of cerebrospinal fluid one direction stream.While adopting drainage system to carry out cerebrospinal fluid puncturing drainage, not only can prevent cerebrospinal fluid reverse flow, the infection of avoiding cerebrospinal fluid reverse flow to bring, reduces operation risk; But also can avoid using drainage bottle device, facilitate medical personnel's operation technique, reduced the manufacturing cost of drainage system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the internal structure schematic diagram of this utility model connector.
In figure: 1, drainage tube; 2, connector; 2-1, body; 2-2, connection tube; 2-3, medical plastic bucket film; 2-4, wing; 3, female Luer; 4, water only; 5, drainage bag; .
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, can prevent the lumbar cistern drainage device of liquid countercurrent, comprise drainage bag 5, the drainage tube 1 that is connected with body on it and the connector 2 being connected with drainage tube one end, on described drainage bag body, be provided with water only 4 and female Luer 3.Described connector 2 comprises that body 2-1 and one end insert intrinsic connection tube 2-2, and described connection tube inserts intrinsic one end outer cover medical plastic bucket film 2-3 is housed, and described medical plastic bucket film one end and connection tube are affixed, and the other end is duckbilled closed form.When liquid forward passes through medical plastic bucket film, liquid normally flows out; During liquid reverse flow, the pressure that is subject to liquid due to medical plastic bucket film, in closure state, cannot reflux liquid, and then realizes the effect of liquid one direction stream.
In the present embodiment, described connector body shaft be upwards shaped be convenient to medical personnel hand-held symmetrically and the wing 2-4 being connected as a single entity with it.
The embodiment that this utility model accompanying drawing is described is exemplary, only for explaining this utility model, and can not be interpreted as restriction of the present utility model.
During use, patient's waist great Chi place is inserted in drainage tube 1 one end with holes, the other end is connected with the tapering point of connector 2 after having cerebrospinal fluid to flow out, cerebrospinal fluid is from connector flows out, again the other end of connector 2 is connected with female Luer, by female Luer, cerebrospinal fluid is flowed into for collecting in the drainage bag 5 of cerebrospinal fluid.When liquid forward passes through medical plastic bucket film, liquid normally flows out; During liquid reverse flow, the pressure that is subject to liquid due to medical plastic bucket film, in closure state, cannot reflux liquid, and then realizes the effect of liquid one direction stream.
Claims (2)
1. the lumbar cistern drainage device that can prevent liquid countercurrent, comprise the drainage bag that is connected with body on it, be arranged on water on drainage bag body only with female Luer, drainage tube and the connector that is connected with drainage tube one end, it is characterized in that: described connector comprises that body and one end insert intrinsic connection tube, described connection tube inserts intrinsic one end outer cover medical plastic bucket film is housed, described medical plastic bucket film one end and connection tube are affixed, and the other end is duckbilled closed form.
