Disposable high negative pressure drainage device

Abstract

The invention discloses a disposable high negative pressure drainage device. The disposable high negative pressure drainage device comprises a high negative pressure drainage bottle and a drainage needle; the high negative pressure drainage bottle contains a transparent bottle body; by a partition plate, the interior of the bottle body is divided into two or more high negative pressure spaces which are not communicated inside the bottle body; a drainage catheter with a switch device is correspondingly arranged on the bottle body above each high negative pressure space and connected with the drainage needle; through puncturing the position to be drained, the drainage needle conducts drainage under the negative pressure action in the high negative pressure drainage bottle. According to the scheme, the disposable high negative pressure drainage device can correspond to two wounds, thereby reducing the quantity of the high negative pressure drainage bottles used on a patient body, facilitating the movement of the patients, and saving the medical cost; and the drainage needle can reduce the wound to the patients through pulling out a needle core and utilizing a needle tube for drainage, facilitates the drainage of an indwelling catheter, and the drainage efficiency can be improved.

Description

technical field [0001] The invention relates to a drainage device, in particular to a practical, portable and more suitable disposable high negative pressure drainage device for treating closed wounds, which belongs to the technical field of medical appliances. Background technique [0002] When a person undergoes an operation or receives a closed injury, the wound is usually accompanied by symptoms such as congestion, edema, and joint cavity effusion, and these fluids need to be excreted by artificial means; The congestion and gas between the muscles are discharged, so that the skin is reset and attached to the muscles to gradually heal; at this time, a negative pressure drainage device for the treatment of these closed injuries is needed; the drainage device generally includes a drainage bottle and a drainage needle, and the general drainage When the bottle is in use, one bottle can only correspond to one drainage site. Therefore, when there are multiple injuries on the pa...

[0002] When a person undergoes an operation or receives a closed injury, the wound is usually accompanied by symptoms such as congestion, edema, and joint cavity effusion, and these fluids need to be excreted by artificial means; The congestion and gas between the muscles are discharged, so that the skin is reset and attached to the muscles to gradually heal; at this time, a negative pressure drainage device for the treatment of these closed injuries is needed; the drainage device generally includes a drainage bottle and a drainage needle, and the general drainage When the bottle is in use, one bottle can only correspond to one drainage site. Therefore, when there are multiple injuries on the patient's body that need drainage, multiple drainage bottles are often hung on the body, which brings a lot of inconvenience to the patient's actions; When the drainage needle is used to deal with closed wounds, the needle is inserted into the position that needs drainage for drainage, and the drainage takes a certain amount of time. At this time, if people need to move, the sharp needle will cause harm to the human body, especially for children. This kind of active group is very dangerous; if you use needles to extract tube by tube, it will be too cumbersome, and multiple needles will cause unnecessary trauma to the human body
