Description

A simple negative pressure drainage device

technical field

The utility model relates to a simple negative pressure drainage device.

Background technique

Nowadays, the efficacy of using negative pressure technology to treat complex wounds has been affirmed, especially VSD technology can be applied to the wound treatment of trauma, burns, osteomyelitis, pressure sores, long-term wounds and diabetic feet. But the cost of VSD is expensive, only the material cost, about 2,000 yuan for a single-tube VSD material (15cm×15cm), and about 3,000 yuan for a double-tube VSD material (15cm×10cm). Moreover, the negative pressure drainage devices on the market are bulky and inconvenient to operate. For patients, it is very inconvenient to go to a hospital to obtain effective treatment.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the existing negative pressure drainage device, the utility model provides a simple negative pressure drainage device with low cost, simple operation and portability.

The technical solution of the utility model to solve the technical problem is: a simple negative pressure drainage device, including a dressing, a drainage tube and a disposable negative pressure drainage bag, the front end of the drainage tube is provided with a side hole, and the dressing completely covers the The top and side holes of the drainage tube, the end of the drainage tube is sealed and connected with the disposable negative pressure drainage bag;

It also includes a transparent film, the transparent film completely covers the dressing;

The disposable negative pressure drainage bag is provided with an elastic support, and the disposable negative pressure drainage bag is also provided with a closable discharge port.

Further, the elastic support member is hollow inside, and the front end of the elastic support member communicates with the drainage tube.

Further, it also includes a syringe, the nipple of the syringe is provided with a disposable scalp needle, and the disposable scalp needle is inserted into the discharge port.

Further, a limit rod is also included. When the piston handle of the syringe is pulled out, the limit rod is stuck between the mouth of the syringe and the piston handle.

Further, the outer surface of the disposable negative pressure drainage bag is provided with measurement scale marks.

Further, the transparent film is a PVA transparent film.

Further, the drainage tube is a disposable sputum suction tube.

The beneficial effects of the utility model are: the equipment used in the utility model is taken from common medical equipment, the whole device is small in size, easy to operate, the patient can use it at home, and the cost is reduced to more than 100 yuan, and the price is easier for the patient Accept; the hollow support not only plays a supporting role, but also draws out the fluid to the bottom of the disposable negative pressure drainage bag regularly, and prevents the phenomenon of sucking back; the transparent film plays a sealing role, and can also be observed intuitively According to whether the transparent membrane is collapsed or not, the effect of negative pressure can be judged; in addition, the negative pressure intensity of the whole device can be adjusted by the syringe.

detailed description

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

Referring to Figure 1 and Figure 2, a simple negative pressure drainage device includes a dressing 1, a drainage tube 2 and a disposable negative pressure drainage bag 3, the front end of the drainage tube 2 is provided with a side hole 4, and the dressing 1 is completely Cover the top of the drainage tube 2 and the side hole 4, the end of the drainage tube 2 is sealed and connected with the disposable negative pressure drainage bag 3, in this embodiment, also includes a transparent film 5, the transparent film 5 is a transparent film made of PVA, and the transparent film 5 completely covers the dressing 1 . When in use, the transparent film 5 is in close contact with the patient's body surface, because the transparent film 5 provides a sealed environment, and the side hole 4 on the drainage tube 2 can make the drainage effect better.

The disposable negative pressure drainage bag 3 is provided with an elastic support member 6, and the disposable negative pressure drainage bag 3 is also provided with a discharge port 7 which can be closed. In this embodiment, the elastic support member 6 is hollow inside, and the front end of the elastic support member 6 communicates with the drainage tube 2, which can effectively prevent fluid from splashing and prevent back suction from occurring.

When in use, first open the discharge port 7, squeeze the elastic support 6, discharge the gas in the disposable negative pressure drainage bag 3, and then close the discharge port 7, Make the device form a negative pressure environment. When drawing more fluid, the discharge port 7 can be opened to discharge the fluid.

In this embodiment, a syringe 8 is also included, and the nipple 9 of the syringe 8 is provided with a disposable scalp needle 10 , and the disposable scalp needle 10 is inserted into the discharge port 7 .

It also includes a limit rod. When the piston handle 11 of the syringe 8 is pulled out, the limit rod is stuck between the barrel mouth 12 of the syringe 8 and the piston handle 11 to prevent the piston from resetting. In this embodiment, the stop bar adopts the needle cover 13 on the syringe, which saves cost and is convenient for obtaining materials.

In this embodiment, the outer surface of the disposable negative pressure drainage bag 3 is provided with a measurement scale mark 14, which is convenient for observing the condition of the fluid.
