Description

A drainage bag with adjustable volume

technical field

The invention relates to the technical field of drainage bags, in particular to a drainage bag with adjustable volume.

Background technique

External drainage of effusion is a drainage method commonly used in medicine. It surgically inserts a catheter connected to a drainage bag into the wound cavity or body cavity, and automatically drains the effusion in the cavity through negative pressure. Therefore, it has the advantages of high drainage quality and is beneficial to prevent infection. It can relieve the compression of nearby organs and blood vessels, improve symptoms, and promote wound healing, so it is widely used clinically. However, different surgical operations have different drainage characteristics, such as: massive and rapid pleural drainage can lead to reexpansion pulmonary edema and mediastinal swing; excessive drainage of cerebrospinal fluid can lead to intracranial hemorrhage and chronic subdural hematoma; excessive drainage of the abdominal cavity can lead to Lead to a sudden drop in abdominal pressure and induce hepatic encephalopathy. Therefore, in order to prevent medical risks caused by inappropriate drainage methods, different drainage schemes such as intermittent drainage and quantitative drainage should be adopted accordingly.

At present, the existing drainage bags are drainage bags with fixed volume, and Fig. 1 is a drainage bag in the prior art. As shown in Figure 1, the drainage bag includes: a transparent bag body 101 with an inner cavity, a drainage tube 102 communicated with the top of the inner cavity, a drain tube 103 communicated with the bottom of the inner cavity, and a transparent bag body 101 top. Suspension strap 104. The transparent bag body 101 is longitudinally provided with a scale line 105 for displaying the liquid volume in the inner cavity, and the scale value corresponding to the scale line 105 increases from bottom to top, that is, medical staff and patients correspond to the liquid level in the drainage bag. to observe the drainage volume.

In order to achieve intermittent drainage or quantitative drainage, a Chinese utility model patent (CN203886010U) discloses an electronic drainage tube clamp suitable for drainage bags, including a body, a lower hook, a pressure sensor, a display module, a control module and a clamping device; The above-mentioned body includes a panel, and the panel is provided with a display screen, and the display screen is electrically connected to the above-mentioned display module; the above-mentioned lower hook is arranged at the lower end of the above-mentioned body, and is connected with the above-mentioned pressure sensor; the pressure sensor is arranged inside the body, It is electrically connected with the above-mentioned display module; the display module receives the data uploaded from the pressure sensor and displays the data on the display screen; the above-mentioned control module is electrically connected with the above-mentioned clamping device and controls the opening and closing of the clamping device, and the clamping device accommodates The drainage tube goes through.

Based on the electronic drainage tube clamper with the above structure, the drainage bag or drainage bottle is hung on the lower hook, and the pressure sensor receives the gravity value change from the lower hook and displays it on the display screen, without the need for medical staff and patients. You can easily lean over to observe the scale of the drainage bag or drainage bottle, and you can easily know the drainage volume just by observing the display screen, and you can open the switch of the clamping device according to the needs of the disease, so as to clamp the drainage tube in time.

Although the electronic drainage tube clamp with the above structure can monitor the drainage volume and clamp the drainage tube in time, it can realize interval drainage or quantitative drainage. However, due to its complex structure and high manufacturing cost, it is difficult to popularize and use it on a large scale.
