Abstract
The utility model discloses a sustainable medical negative pressure drainage device which comprises a liquid storage bag and a drainage catheter. The liquid storage bag is provided with a liquid outlet. The sustainable medical negative pressure drainage device is characterized in that the sustainable medical negative pressure drainage device further comprises a negative pressure bottle, the upper end of the negative pressure bottle is provided with a liquid filling port and an exhaust port, the lower end of the negative pressure bottle is provided with a discharge port, and the liquid filling port and the exhaust port are both provided with plugs which can be opened. One end of the drainage catheter is inserted into the negative pressure bottle, and the insertion end of the drainage catheter is lower than the discharge port of the negative pressure bottle; the discharge port of the negative pressure bottle is communicated with the liquid storage bag through a discharge tube, and an opening and closing valve is arranged on the discharge tube or the discharge port; an anti-reflux valve is arranged at the position, located at a connector of the discharge port, in the liquid storage bag so as to prevent liquid from flowing back and entering the discharge tube. The sustainable medical negative pressure drainage device has the advantages of being small in size, convenient to carry and capable of generating certain negative pressure without a power source, after the negative pressure is generated, sustainable drainage can be achieved due to the siphonage phenomenon, and the sustainable medical negative pressure drainage device is very convenient to use and relieves burden of patients and carers.
Description
Technical field
This utility model relates to the improvement of clinical drainage way, specifically refers to a kind of continuable medical negative pressure drainage device, belongs to technical field of medical instruments.
Background technology
Clinically, often need patient to implement drainage, so that drain is discharged.Drainage bag be Hospitals at Present as postoperative drainage use at most, one of medical drainage apparatus the most widely.Drainage bag is normally formed by the heat seal of double-deck PVC thin film, and heated double-deck PVC thin film, as storing bag, stores on bag and has PVC flexible pipe to be connected with drain position as drainage catheter.Using common drainage bag to carry out drain, is mainly by drain self gravitation or draining hole exudate pressure-acting, flows out toward lower from eminence, and drainage bag itself can not produce negative pressure, belongs to passive drain.Therefore current medical drainage bag, just possesses simple fluid storage function.
Summary of the invention
For prior art above shortcomings, the purpose of this utility model is to provide a kind of easy to use, the medical negative pressure drainage device that can realize constant drainage by siphonage.
The purpose of this utility model is achieved in that
A kind of continuable medical negative pressure drainage device, comprises liquid storing bag and drainage catheter, is provided with leakage fluid dram on liquid storing bag.It is characterized in that: also comprise negative pressure bottle, negative pressure bottle upper end is provided with filling opening and air vent, and lower end is provided with floss hole, on filling opening and air vent, be equipped with openable plug.Drainage catheter one end insert in negative pressure bottle and insertion end lower than negative pressure bottle floss hole height; The floss hole of negative pressure bottle communicates with liquid storing bag by delivery pipe, on delivery pipe or floss hole, is provided with switch valve; In liquid storing bag, being positioned at delivery pipe seam is provided with valve for preventing reverse-flow and enters delivery pipe to prevent liquid return.
Described filling opening and air vent also can share an opening and plug.
Between described negative pressure bottle and liquid storing bag, connect by fixture.
This utility model using method and principle are described below:
First in negative pressure bottle, inject a certain amount of liquid by filling opening, liquid level is higher than floss hole, then respectively with plug sealing filling opening and air vent.Then drainage catheter is connected with needs drain position, finally open the switch valve under negative pressure bottle, liquid in negative pressure bottle flow to liquid storing bag naturally because of gravity reason, negative pressure bottle is interior because air space increases in confined conditions, cause the certain negative pressure of generation in bottle, thereby reach the object of clinical negative pressure drainage.Drain liquid is out introduced negative pressure bottle by drainage catheter, then enters liquid storing bag by negative pressure bottle and delivery pipe, utilizes siphonage to realize drain endlessly.
The utlity model has volume little, be convenient for carrying and also can produce the advantages such as certain negative pressure without power supply, negative pressure produce after due to just sustainable drain of siphonage, very convenient, alleviated patient and caretaker's burden.
Accompanying drawing explanation
Fig. 1-this utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, from scheming, can find out this utility model medical negative pressure drainage device, comprise liquid storing bag 7, negative pressure bottle 11 and drainage catheter 1, negative pressure bottle 11 upper ends are provided with filling opening 2 and air vent 3, and lower end is provided with floss hole 4, are equipped with openable plug 12 on filling opening 2 and air vent 3.Drainage catheter 1 one end insert in negative pressure bottle 11 and insertion end lower than negative pressure bottle floss hole 4 height; The other end carries out drain in insertosome.The floss hole 4 of negative pressure bottle communicates with liquid storing bag 7 by delivery pipe 13, on delivery pipe 13 or floss hole 4, is provided with switch valve 5, is positioned at delivery pipe seam and is provided with valve for preventing reverse-flow 6 and enters delivery pipe 13 to prevent liquid return in liquid storing bag 7.On liquid storing bag 7, be provided with leakage fluid dram 8, just can discharge by leakage fluid dram when reaching after a certain amount of.
Described filling opening and air vent also can share an opening and plug, and only otherwise aerofluxus while affecting liquid feeding, both unite two into one, with simplified structure and processing.
Between described negative pressure bottle 11 and liquid storing bag 7, connect the actual use of being more convenient for by fixture 9.
This utility model using method and principle are described below:
First in negative pressure bottle 11, inject a certain amount of liquid 10 by filling opening 2, liquid level is higher than floss hole, therefore drainage catheter is embedded in liquid; Then seal filling opening 2 and air vent 3 with plug 12 respectively.Then drainage catheter is connected with needs drain position, finally open the switch valve 5 under negative pressure bottle, liquid 10 in negative pressure bottle flow to liquid storing bag 7 naturally because of gravity reason, negative pressure bottle is interior because air space increases in confined conditions, cause the certain negative pressure of generation in bottle, thereby reach the object of clinical negative pressure drainage.Drain liquid is out introduced negative pressure bottle 11 by drainage catheter 1, then enters liquid storing bag 7 by negative pressure bottle 11 and delivery pipe 13, utilizes siphonage to realize drain endlessly.
The utlity model has volume little, be convenient for carrying and also can produce the advantages such as certain negative pressure without power supply, negative pressure produce after due to just sustainable drain of siphonage, very convenient, alleviated patient and caretaker's burden.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
