Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a negative pressure drainage device. Background Art

[0002] In medical practice, negative pressure drainage devices are common medical equipment and are widely used for drainage of fluid accumulation after surgical operations, such as in the chest cavity, abdominal cavity, surgical wounds, etc. For example, drainage after breast cancer surgery plays an important role in recovery. Fluid often accumulates in the area where the breast is removed. If the fluid is not emptied, it may cause discomfort and delay healing. In order to avoid cross infection, disposable negative pressure drainage devices are usually used.

[0003] In order to keep the drainage bottle in a negative pressure state, the disposable negative pressure drainage device is usually made of soft materials. However, the existing device does not have measures to protect the drainage bottle, which causes the drainage liquid to reflux when the drainage bottle is touched or squeezed, increasing the risk of infection. In addition, when replacing the drainage bottle, the drainage bottle is not sealed, which easily causes the liquid in the drainage bottle to spill. Therefore, we propose a negative pressure drainage device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that the drainage bottle is not protected, resulting in reflux of liquid in the drainage bottle when it is hit or squeezed, increasing the risk of infection, and the drainage bottle is not sealed, which easily causes the liquid in the drainage bottle to spill when the liquid in the drainage bottle is replaced or handled, and to propose a negative pressure drainage device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A negative pressure drainage device, comprising:

[0007] Drainage bottle, which is made of soft polyvinyl chloride plastic and is used to store the drained liquid;

[0008] A drainage hose, which is connected to the drainage bottle and is used to drain the liquid into the drainage bottle;

[0009] Infusion regulator: The infusion regulator is mounted on the drainage hose and is used to adjust the speed of drainage;

[0010] The device also includes:

[0011] A protection component, which is arranged on the outside of the drainage bottle and is used to protect the drainage bottle;

[0012] The fixing component is arranged between the drainage bottle and the drainage hose and is used to fix the drainage bottle and the drainage hose.

[0013] In one possible design, the protective assembly includes two protective shells, which are hingedly connected to form an elliptical protective cover. The drainage bottle is located in the two protective shells for protecting the drainage bottle. Guide openings are provided on the tops of the two protective shells to facilitate the hose connected to the drainage bottle to extend out of the two protective shells.

[0014] In one possible design, a fixing block made of soft rubber material is fixedly connected to the outer side of one protective shell, and a clamping ring is fixedly connected to the outer side of the other protective shell. The clamping ring is sleeved on the fixing block and is used to fix the two protective shells when they form an elliptical protective cover.

[0015] In a possible design, a hanging opening is fixedly connected to the outer side of one of the protective shells for easy carrying or hanging.

[0016] In one possible design, the fixed assembly includes a stop valve, the bottom end of the stop valve is fixedly connected to the top of the drainage bottle, one end of the drainage hose is fixedly connected to a drainage hard tube, a fixed tube is slidably connected to the drainage hard tube, the inner wall of the fixed tube is provided with an internal thread, a fixing ring is provided on the drainage hard tube located inside the fixed tube, the outer wall of the liquid inlet end of the stop valve is provided with a threaded section, and the fixed tube is threadedly connected to the liquid inlet end of the stop valve.

[0017] In a possible design, the top and the bottom of the fixing ring are fixedly connected to soft rubber rings for sealing when the fixing pipe is connected to the stop valve.

[0018] In the present application, firstly, it is detected whether the stop valve is in a closed state, and at the same time, it is detected whether the drainage bottle is leaking. Then, the drainage bottle is placed inside one of the protective shells, and then the other protective shell is rotated to completely wrap the drainage bottle inside, and then the clamp ring is bent to make the clamp ring fit on the fixed block to fix the two protective shells to prevent the two protective shells from opening and the drainage bottle from falling therefrom. Then, the drainage hose is connected to the stop valve on the drainage bottle through the drainage hard tube, and the fixed tube on the drainage hard tube is threadedly connected to the stop valve, and then the fixed ring is used to limit the position of the fixed tube, and at the same time, the rubber ring on the fixed ring is used to seal the fixed tube, so that the drainage hose and the stop valve are fixed to prevent leakage, and finally, the other end of the drainage hose is connected to the drainage tube in the patient's body, and then the stop valve is rotated to connect the drainage bottle with the drainage hose, and the liquid is introduced into the drainage bottle through the drainage hose through the negative pressure in the drainage bottle, and then the infusion regulator is adjusted to make the drainage liquid speed reach the speed adapted to the patient, and at the same time, the drainage bottle is conveniently hung or carried through the hanging port on the protective shell.

[0019] During the drainage process, if the drainage bottle needs to be replaced or the liquid in the drainage bottle needs to be poured out due to excessive liquid in the drainage bottle, first adjust the infusion regulator to prevent the liquid in the drainage hose from flowing, then turn the stop valve to close the drainage bottle, then turn the fixed tube to disengage the fixed tube from the threaded connection of the stop valve. At this time, since the stop valve is closed, the liquid in the drainage bottle is effectively prevented from flowing out. After pouring out the liquid, squeeze the drainage bottle to discharge the air in the drainage bottle, then close the stop valve to put the drainage bottle in a negative pressure state, then connect it to the drainage hose, and finally open the stop valve and adjust the infusion regulator to connect the drainage bottle to the drainage hose to continue drainage. If replaced, directly connect it to the drainage hose, open the stop valve and adjust the infusion regulator to continue drainage.

[0020] Beneficial effects:

[0021] In the utility model, the negative pressure drainage device adopts two hinged protective shells to form an elliptical protective cover, which has a simple structure and is easy to operate, and can effectively protect the drainage bottle. At the same time, the guide port provided on the protective shell facilitates the extension of the drainage hose without affecting the drainage operation.

[0022] In the utility model, the negative pressure drainage device can conveniently fix the two protective shells through the cooperation of the fixing block and the clamp ring, thereby ensuring the stability of the protective cover. At the same time, the setting of the hanging opening makes it convenient for medical staff to carry or hang the device, thereby improving the convenience of use.

[0023] In the utility model, the negative pressure drainage device adopts a combination of a stop valve, a drainage hard tube, a fixing tube and a fixing ring through a fixing component, has a compact structure and is firmly fixed. It can effectively prevent the connection between the drainage hose and the drainage bottle from loosening or falling off, and at the same time, effectively prevent the liquid in the drainage bottle from spilling when replacing.

[0024] In the utility model, the elliptical protective cover formed by the protective shells connected by two hinges can effectively protect the drainage bottle, and the two protective shells can be conveniently fixed by the fixing block and the clamping ring. By adopting the combination of the stop valve, the drainage hard tube, the fixing tube and the fixing ring, the connection between the drainage hose and the drainage bottle can be effectively prevented from loosening or falling off, and at the same time, the liquid in the drainage bottle can be effectively prevented from spilling when replacing.
