Abstract
The utility model relates to a negative pressure drainage device which comprises an upper circular end cover and a lower circular end cover; the two end covers are respectively sealed on both ends of a soft transparent cylinder; a compression spring is arranged between the two end covers; both ends of the compression spring are inlaid in positioning bulge loops on the inner surfaces of the end covers; the upper end cover is provided with a suction port and an exhaust port; the suction inlet is connected with a suction tube with a switch; and the exhaust port is provided with a sealing plug. The negative pressure drainage device is used for the pressure reduction of intestines and stomach and the negative pressure drainage after an internal drainage tube surgery, is disposable, prevents cross infection, has simple structure and low cost, is not easy to be damaged and carried, is convenient for the patients to move, is convenient to be operated, and can improve the working efficiency of medical staff.
Description
Technical field:
This utility model relates to a kind of medical depression drainage device, is mainly used in gastrointestinal decompression, the built-in drainage tube postoperative negative pressure drainage of operation.
Background technology:
Former depression drainage device is made of negative pressure suction device and two water-sealed drainage bottles, surge pipe, drainage tubes, and device is complicated, the cost height, and easily cross infection is difficult for moving in case of necessity.In clinical course, be unfavorable for patient activity, and complicated operation increases the weight of nurse's burden of working.
Summary of the invention:
The purpose of this utility model provides a kind of depression drainage device, and disposable use solves the technological deficiency that former depression drainage device carries inconvenience, cost height, complicated operation.
The purpose of this utility model realizes as follows: it has the end cap of two circles up and down, two end cap difference seal buckle is at the cylindrical shell two ends of soft transparent, the compression spring is set between the two end cap, the two ends of compression spring are embedded in the positioning convex ring of end cap inner face, on the top end cap suction inlet and outlet are set, the suction tube of suction inlet connecting band switch installs sealing-plug on the outlet.
The compression spring be the two ends diameter big, to the Spring capable of diameter varying that the middle part diameter diminishes gradually, reduce greatly than the height after the cylindrical spring compression.
On the top end cap suspender belt is set, suspender belt can be convenient to the fixing of drainage device.
Be connected with connecting rope between sealing-plug and the top end cap, avoid sealing-plug to lose.
During use, the suction tube of belt switch is docked with gastrointestinal decompression, the built-in drainage tube of operation, and close switch, open sealing-plug, press end cap downwards according to required pressure, thereby make the compression spring be compressed certain altitude, then the sealing-plug plug is sealed on outlet, the switch of opening on the suction tube is sustainable attraction.After the drain of liquid gas, open sealing-plug, drain liquid is outwelled by outlet.
The beneficial effects of the utility model are: disposable use, prevent cross infection, and cost simple in structure is low, and cracky is not easy to carry about with one, and makes things convenient for patient activity, and is easy and simple to handle, can improve medical personnel's work efficiency.
Description of drawings:
Accompanying drawing is the structural representation of this utility model depression drainage device.
The specific embodiment:
With reference to accompanying drawing, it has the end cap 1 of two circles up and down, two end caps 1 are sealed in cylindrical shell 2 two ends of soft transparent respectively, cylindrical shell 2 can be made with flexible plastic, compression spring 4 is set between the two end cap 1, compression spring 4 is that the two ends diameter is big, the Spring capable of diameter varying that diminishes gradually to the middle part diameter, the two ends of compression spring 4 are embedded in and prevent skew in the positioning convex ring 3 of end cap inner face, on the top end cap 1 suction inlet 5 and outlet 7 are set, the suction tube 6 of suction inlet 5 connecting band switches, device sealing-plug 8 is connected with connecting rope between sealing-plug 8 and the top end cap 1 on the outlet 7, on the top end cap 1 two hangers are set, are connected with suspender belt 9 between two hangers.For convenient metering, scale 10 is set on the outer surface of cylindrical shell 2, be used to measure the drain liquid measure.
