Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

As shown in figure 1, the special gauge for the disposable negative pressure drainage device comprises a spherical liquid containing cavity and a cylindrical conduit, wherein the liquid containing cavity is arranged at the top of the conduit, and the liquid containing cavity and the conduit can be integrally manufactured. The liquid holding cavity and the catheter are made of transparent low-density polyethylene (LDPE), and scales are marked on the outer surface.

In this example, the diameter D1 of the liquid-containing chamber was 7.5cm, and the total volume was 220 ml. When the special gauge is used, the liquid containing cavity part needs to be squeezed, but the single squeezing cannot completely exhaust the air, the conduit part cannot be completely placed in the liquid, and a certain degree of air leakage exists. When the liquid containing cavity is extruded once, in order to ensure that the air in the cavities 1/2-2/3 has the liquid absorbing capacity of 100ml once after being exhausted, the diameter of the liquid containing cavity is preferably 7.5cm, and the volume of the position where the maximum scale value of 100ml is located accounts for half of the total volume of the liquid containing cavity. As shown in FIG. 2, the outer surface of the liquid containing chamber is marked with scales of 25ml, 40ml, 60ml, 80ml and 100ml from bottom to top in sequence. The distance H1 between the 25ml scale values and the top of the catheter was 1.5cm, and the height differences H2 to H4 between the 25ml, 40ml, 60ml, 80ml and 100ml scale values were 0.5cm, respectively.

The outer surface of the catheter is marked with scales of 0.5ml, 1ml and 1.5ml from bottom to top in sequence. As shown in figure 3, in order to be used with the disposable negative pressure drainage device, the diameter of the conduit of the special gauge is consistent with the inner diameter of the top opening of the disposable negative pressure drainage device, and the height of the conduit is consistent with that of the disposable negative pressure drainage device. In this example, the diameter D2 of the catheter was 0.5cm, the height H6 was 10cm, and the volume of the catheter was 2 ml.

The volume of the liquid drainage quantity of the negative pressure drainage device measured by the special gauge is the sum of the volume of the liquid in the liquid containing cavity and the volume of the liquid in the catheter. For example, if the liquid to be aspirated is located at the position of the liquid holding chamber, 1.5cm from the top of the catheter, i.e., at a scale value of 25ml, the total volume of the liquid should be the volume of the interior of the catheter plus the volume of the liquid in the liquid holding chamber. The volume of the catheter is 2ml, and the liquid volume in the liquid accommodating cavity can be calculated according to the sphere segment volume formula pi H1²(1/2D1-H1/3), namely 23 ml. D1 is the diameter of the liquid containing cavity of 7.5cm, and H1 is the distance of the liquid from the top of the catheter of 1.5 cm. Thus, the total volume of liquid at this time was 2ml plus 23ml, which was 25 ml.

The utility model discloses the theory of use of the special counter of disposable negative pressure drainage ware as follows: an operator holds the special meter by hand, and squeezes the liquid containing cavity by fingers to discharge air in the liquid containing cavity, so that the interior of the liquid containing cavity is in a negative pressure state. Then the catheter of the special gauge is inserted into the top opening of the disposable negative pressure drainage device, the fingers are released, and the liquid in the disposable negative pressure drainage device is sucked into the liquid containing cavity. The accurate volume of the liquid can be read according to the scale value on the outer surface of the liquid containing cavity.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
