AI Technical Summary
Existing VSD drainage devices are expensive and only applicable to one wound, which cannot meet the needs of multiple wounds and increases the medical costs for patients.
Using low-cost, common hospital components such as three-way connectors, suction tubes, drainage tubes, and transparent dressings, multiple negative pressure closed drainage units are connected in series through the central drainage tube to form a self-made VSD drainage device, which is then connected to a negative pressure source to achieve negative pressure closed drainage.
A low-cost VSD drainage device has been developed, which can meet the needs of patients with multiple wounds and reduce medical costs.

[0007] Self -made VSD drainage device, including at least one negative pressure closed drainage unit, a plurality of negative pressure closed drainage units are connected in series through intermediate drainage pipe, the negative pressure closed drainage unit includes three -way pipe joint, sputum suction tube, drainage pipe and transparent application, one of three -way pipe joint is inserted with sputum suction tube, the sputum suction tube front end is placed in patient's wound, and the wound is covered and closed with transparent application, and the remaining two interfaces are used for inserting drainage pipe, and the other is used for inserting intermediate drainage pipe, the drainage pipe and intermediate drainage pipe are equipped with water stop clamp respectively, the drainage pipe in the negative pressure closed drainage unit located in the most front end is connected with drainage bottle, and the drainage bottle is connected with negative pressure source through connecting pipe.
[0008] The three -way pipe joint, drainage pipe and intermediate drainage pipe are made of double plug infusion apparatus.
[0009] The utility model adopts the above structure, and the following beneficial effects can be brought:
[0010] The application can be quickly assembled into a negative pressure closed drainage structure by using the three-way pipe joint, the sputum suction tube, the drainage tube and the transparent dressing which are easily obtained and low in cost in the hospital, not only has the advantage of low cost, but also can realize multiple series drainage through the intermediate drainage tube, and meets the use of patients with many wound surfaces. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 It is a structure schematic view of the VSD drainage device of the utility model;
[0012] In the figure, 1 is a negative pressure drainage unit, 101 is a three-way pipe joint, 102 is a sputum suction tube, 103 is a drainage tube, 104 is a transparent dressing, 105 is a water stop clamp, 106 is a joint, 2 is an intermediate drainage tube, 3 is a drainage bottle, 4 is a connecting pipe, 5 is a negative pressure source, and 6 is a wound. DETAILED DESCRIPTION
[0013] In order to more clearly illustrate the overall concept of the application, the following will be described in detail in an exemplary manner with reference to the accompanying drawings.
[0014] In the following description, many specific details are set forth in order to provide a thorough understanding of the application, but the application can also be implemented in other ways different from those described herein, therefore, the protection scope of the application is not limited by the specific embodiments disclosed below.
[0015] Each embodiment in the specification is described in a progressive manner, and the same and similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.
[0016] In addition, the terms "transverse", "longitudinal", "vertical" and the like are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the position of the indicated technical features.
