Abstract
A negative pressure drain device comprises a coating material (1) and drain pipes (2); the drain pipes (2) are inserted into a hollow chamber (4) in the coating material (1); the drain pipes (2) are connected with a negative pressure source (7); the negative pressure drain device is characterized in that side holes (3) are uniformly distributed on the drain pipe (2) inserted in the coating material (1); and the utility model is provided with two drain pipes (2) that are arranged at 1/3 position at two sides of the coating material (1) respectively. The negative pressure drain device overcomes the shortages that the existing negative pressure drain device has unreasonable arrangement of drain pipes and pipe holes, does not have a developing structure, and the like. The negative pressure drain device has reasonable layout, simple structure and convenient usage.
Description
Technical field
This utility model relates to a kind of negative pressure drainage device, and it is mainly used in surgical drainage, belongs to medical instruments field.
Background technology
Negative pressure drainage is meant that the drainage tube that will have lapping places human body to need in the wound surface and lacuna of drain, with the intravital clot of people, downright bad fragment of tissue and pus etc., utilizes negative pressure to pass through outside the drainage tube lead body.Lapping quality softness wherein contacts cmpletely with wound surface that needs drain and lacuna.Drainage tube places in the lapping, and the wound surface and the lacuna of direct contact need drain at first are not inhaled in the lapping by drain, is introduced in the drainage tube after plastotype decomposes again, and is siphoned away by high negative pressure immediately.It is unreasonable that but the pore that has drainage tube in the existing negative pressure drainage device is arranged, the location arrangements of drainage tube is unreasonable, shortcomings such as Nonvisualization structure, and these shortcomings have all influenced drainage effect.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing negative pressure drainage device drainage effect difference, and a kind of drainage effect is good, the negative pressure drainage device of accurate positioning and provide.
The purpose of this utility model reaches by following measure: negative pressure drainage device, it comprises lapping, drainage tube, drainage tube inserts in the interior cavity of lapping, drainage tube is connected with negative pressure source, it is characterized in that being evenly distributed with side opening on the drainage tube in the described insertion lapping, described drainage tube has two, and is arranged in 1/3 place of lapping both sides.
In technique scheme, on the described drainage tube that is positioned at lapping iodine radiography line 5 is arranged.
In technique scheme, after connecting by a tee T, described two drainage tubes that are positioned at lapping incorporate a drainage tube again into.
The negative-pressure drainage tube arrangement of this utility model band side opening has following advantage: 1.. and the side arrangement circular hole of drainage tube helps improving drainage effect.Arrange two drainage tubes simultaneously, and two drainage tubes are arranged in 1/3 place of lapping both sides.Drainage tube is identical to captivation all around like this, has improved the effect of drain.2.. the iodine radiography line in the drainage tube can show the position of drainage tube by X-ray, therefore the particular location of lapping fully can be shown, is convenient to lapping accurately is positioned drainage lumens.3.. two drainage tubes in the lapping are incorporated a drainage tube into after connecting by a tee T again, and are simple in structure, easy to use.

The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult accompanying drawing as can be known: this utility model negative pressure drainage device, it comprises lapping 1, drainage tube 2, in the cavity 4 that drainage tube 2 inserts in the lapping 1, drainage tube 2 is connected with negative pressure source 7, insert on the drainage tube 2 in the lapping 1 and be evenly distributed with side opening 3, described drainage tube 2 has two, and is arranged in 1/3 place of lapping 1 both sides.Drainage tube is identical to captivation all around like this, has improved the effect (as Fig. 1, Fig. 2, shown in Figure 3) of drain.
Be positioned on the drainage tube 2 of lapping 1 iodine radiography line 5 is arranged.The particular location of lapping fully can be shown, be convenient to lapping accurately is positioned (as shown in Figure 3) in the drain lacuna.
Two drainage tubes 2 that are positioned at lapping 1 are incorporated a drainage tube 2 into after connecting by a tee T 6 again.(as shown in Figure 1) simple in structure, easy to use.
Claims (3)
